W I T N E S S E T H : WHEREAS, the Borrower is a wholly-owned direct subsidiary of Quest Diagnostics; WHEREAS, Quest Diagnostics and certain of its Subsidiaries as Originators and the Borrower have entered into the Sale Agreement pursuant to which each of the Originators has sold and/or contributed, and hereafter will sell to the Borrower, Participation Interests in all of such Originator’s right title and interest in and to its Specified Government Receivables, all of such Originator’s right, title and interest in and to its Private Receivables and certain related rights; WHEREAS, pursuant to the Existing Agreement, the Groups committed to make Loans to the Borrower from time to time secured by the Collateral, and Quest Diagnostics agreed to act as Servicer; WHEREAS, in addition to the Loans, the Borrower may from time to time hereafter request the LC Issuer to issue Letters of Credit, and the LC Issuer has agreed, subject to the terms and conditions contained in this Agreement, to issue such Letters of Credit; and WHEREAS, the parties 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. 1.1.1. Advances. 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 prior to the Commitment Expiry Date request Advances by delivering a Borrowing Request to the Co-Agents in accordance with Section 2.1. Upon receipt of a copy of each Borrowing Request from the Borrower or Servicer, 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) PNC severally agrees to make a Loan to the Borrower in an amount equal to its Group’s Commitment Percentage of the requested Advance on the terms and subject to the conditions hereof, provided that at no time may the aggregate Principal amount of PNC’s Credit Exposure at any one time outstanding exceed the amount of PNC’s Commitment, and (ii) the PNC Group’s Commitment Percentage of the Borrowing Base (such lesser amount, the “PNC Allocation Limit”); (b) in the event that Gotham elects not to make a Loan to the Borrower in an amount equal to its Group’s Commitment Percentage of the requested Advance, the Gotham Agent shall promptly notify the Borrower and, unless the Borrower cancels its Borrowing Request, each of the Liquidity Banks in the Gotham Group severally agrees to make its Pro Rata 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’ Credit Exposure 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 Commitment Percentage of the Borrowing Base (such lesser amount, the “Gotham Allocation Limit”); and (c) in the event that Atlantic elects not to make a Loan to the Borrower in an amount equal to its Group’s Commitment Percentage of the requested Advance, the Atlantic Agent shall promptly notify the Borrower and, unless the Borrower cancels its Borrowing Request, each of the Liquidity Banks in the Atlantic Group severally agrees to make its Pro Rata 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 Atlantic’s and its Liquidity Banks’ Credit Exposure at any one time outstanding exceed the lesser of (i) the aggregate amount of the Atlantic Liquidity Banks’ Commitments, and (ii) the Atlantic Group’s Commitment Percentage of the Borrowing Base (such lesser amount, the “Atlantic Allocation Limit”); Each Loan (other than an LC Loan) shall be in the minimum amount of $1,000,000 or a larger integral multiple of $500,000. 1.1.2. Letters of Credit. 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 prior to the Commitment Expiry Date request that the LC Issuer issue Letters of Credit for the account of the Borrower, and from time to time upon receipt of a duly executed and completed LC Application, the LC Issuer hereby agrees to issue Letters of Credit and to renew, extend, increase, decrease or otherwise modify each Letter of Credit (“Modify,” and each such action a “Modification”); provided that no Letter of Credit shall be issued or Modified by the LC Issuer if, after giving effect thereto, (a) the LC Obligations would exceed the LC Sublimit, or (b) the Aggregate Credit Exposure would exceed the lesser of (i) the Aggregate Commitment and (ii) the Borrowing Base; and provided, further, that each Letter of Credit issued pursuant to this Section 1.1.2 shall have a face amount of not less than $5,000. On any date of determination, the LC Obligations, whether still contingent or due and payable but unpaid, will constitute usage of the LC Sublimit and, accordingly, the Aggregate Commitment. 1.1.3. Aggregate Credit Exposure; Termination of Commitments; Uncommitted Accordion; Collateral. (a) In no event may the Aggregate Credit Exposure hereunder exceed the lesser of (i) the Aggregate Commitment, or (ii) the Borrowing Base. (b) Each Commitment shall terminate on the earlier to occur of (i) the Commitment Expiry Date and (ii) the Termination Date. (c) Not more than twice during the period from and after November 20, 20242025 and prior to the earlier to occur of the Commitment Expiry Date and the Termination Date, provided that no Event of Default or Unmatured Default exists and is continuing, the Borrower (or the Servicer, on the Borrower’s behalf) may request an increase in the Aggregate Commitment in an aggregate amount during such period not to exceed $200,000,000 across all Groups by delivering not less than three (3) weeks’ prior written notice to the Co-Agents specifying (i) the aggregate amount of the requested increase (the “Aggregate Requested Increase”), (ii) each Group’s Commitment Percentage of the Aggregate Requested Increase (each, a “Group’s

Requested Increase”), and (iii) each Committed Lender’s Pro Rata Share of its Group’s Requested Increase (each, a “Committed Lender’s Increase Amount”). Upon receipt of a written request complying with the preceding sentence, each of the Co-Agents will promptly deliver a copy of such request to the Committed Lender(s) in its Group, and each such Committed Lender will promptly seek credit approval to increase its Commitment in an amount equal to such Committed Lender’s Increase Amount; provided, however, that nothing herein shall be deemed to constitute a commitment by any Lender to provide, or to obtain credit approval to provide, all or any portion of the Aggregate Requested Increase. If any Co-Agent notifies the Loan Parties and the Administrative Agent that any Committed Lender in its Group has obtained credit approval to increase its Commitment by an amount equal to such Committed Lender’s Increase Amount, such Committed Lender’s Commitment and the Aggregate Commitment will automatically increase by such Committed Lender’s Increase Amount on the Business Day at least five (5) Business Days but in any event no more than three (3) weeks after delivery of the request for such increase (unless otherwise approved by the Co-Agents) and at least 30 days prior to the Scheduled Termination Date. In no event will any increase in the Aggregate Commitment pursuant to this Section 1.1.3(c) result in any change to the LC Sublimit. If any Committed Lender declines to agree to increase its Commitment by its Committed Lender’s Increase Amount: (i) the Borrower may ask the Committed Lenders in the other Groups if they would like to increase their respective Committed Lender’s Increase Amounts by all or any portion of the declined amount; or (ii) the Borrower, upon notice to and consent of the Administrative Agent and the LC Issuer (which consent shall not be unreasonably withheld or delayed), may add a new Group that consists of at least one new Committed Lender willing to provide the declining Committed Lender’s Group Requested Increase, and/or replace the declining Committed Lender’s Group in its entirety with a new Group that consists of at least one new Committed Lender willing to provide a replacement Commitment equal to the sum of the replaced Group’s existing Commitment plus its Group Requested Amount. Any change in the Commitments or Groups pursuant to clause (i) or (ii) above will become effective on the first day of the calendar month following confirmation by the Administrative Agent that all documentation necessary to evidence such changes has been executed and delivered. (d) Each of the Loans, the LC Obligations 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) Each Advance hereunder shall consist of Loans made by (i) Gotham and/or its Liquidity Bank(s), (ii) Atlantic and/or its Liquidity Bank(s), and (iii) PNC, and (except for any Advance which does not increase Aggregate Principal) 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.

(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 (i) in the case of the proceeds of an LC Loan, to the account specified by the LC Issuer, and (ii) in the case of the proceeds of a Loan, to the account specified by the Borrower in its Borrowing Request, in each of the foregoing cases, 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 any Conduit 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 Term SOFR 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. (a) Prior to the occurrence of an Event of Default and during the continuance thereof, each Loan shall bear interest at the applicable Interest Rate, payable in arrears on each Settlement Date. Notwithstanding the foregoing, 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; provided that no Interest at the Default Rate shall accrue or be payable to a Defaulting Lender so long as such Lender shall be a Defaulting Lender. (b) Each Term SOFR 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 rate per annum equal to the applicable Adjusted Term SOFR rate for such Interest Period. (c) 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. (d) Each Alternate Base Rate Loan and each Daily Term SOFR Loan, respectively, 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 rate per annum equal to the Alternate Base Rate or the applicable Daily Term SOFR rate, respectively, for such day. Changes in the rate of Interest on Alternate Base Rate Loans and Daily Term SOFR Loans will take effect simultaneously with each change in the Alternate Base Rate or the applicable Daily Term SOFR rate, respectively. (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 Repayment of the Advances. (a) [Reserved]. (b) Unless the Termination Date has earlier occurred, on the Commitment Expiry Date, the Advances and LC Advances shall become due and will be payable on Settlement Dates to the extent of Collections received on the Commitment Expiry Date and each Business Day thereafter until paid in full, together with all accrued and unpaid Interest thereon. In addition to the foregoing, unless the Termination Date has earlier occurred, on the Commitment Expiry Date and on each Settlement Date thereafter, the LC Obligations shall be required to be Cash Collateralized to the extent of Collections received on the Commitment Expiry Date and each Business Day thereafter until paid or Cash Collateralized in full, together with all Expected LC Fees. (c) All payments and Cash Collateral Payments required under Section 1.4(b) shall be made on Settlement Dates occurring on or after the Commitment Expiry Date in the order of priority specified in Section 3.2(d).

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 applicable Commitment Expiry Date.

(e) Unless the Co-Agents shall have received written notice by 12:00 noon2:00 p.m. (New York City time) on the first (1st) Business Day prior to the last day of an Interest Period that the Borrower intends to reduce the aggregate Principal amount of the Term SOFR Loans outstanding from the Liquidity Banks, each of the Liquidity Banks shall be entitled to assume that the Borrower desires to refinance its maturing Term SOFR Loans on the last day of such Interest Period with Alternate Base Rate Loans.

Requirements of Law, and (iv) within 30 days after the date of such payment, such Loan Party shall furnish to the Administrative Agent (which shall forward the same to such Agent or such Lender) the original or a certified copy of a receipt evidencing payment thereof, to the extent such receipt is issued therefor, or other written proof of payment thereof that is reasonably satisfactory to the Administrative Agent.

If the Borrower so requests in any LC Application, the terms of the related Letter of Credit may include customary “evergreen” provisions providing that such Letter of Credit’s expiry date shall automatically be extended for additional periods not to exceed twelve (12) months unless, not less than thirty (30) days (or such longer period as may be specified in such Letter of Credit) (the “Notice Date”) prior to the applicable expiry date, the LC Issuer delivers written notice to the Borrower and the beneficiary thereof declining such extension; provided, however, that if (1) any such extension would cause the expiry date of such Letter of Credit to occur after the date that is twelve (12) months after the Commitment Expiry Date (or such longer period of time as may be approved in an Email or other writing by each of the LC Issuer and the Co-Agents) or (2) the LC Issuer

determines that any condition precedent (including, without limitation, those referenced in Section 2.7 (a) hereof) to issuing such Letter of Credit hereunder (as if such Letter of Credit were then being first issued) are not satisfied (other than any such condition requiring the Borrower to submit an LC Application in respect thereof), then the LC Issuer, in the case of clause (1) above, may (or, at the written direction of any Committed Lender, shall) or, in the case of clause (2) above, shall, use reasonable efforts in accordance with (and to the extent permitted by) the terms of such Letter of Credit to prevent the extension of such expiry date (including notifying the Borrower and the beneficiary of such Letter of Credit in writing prior to the Notice Date that such expiry date will not be so extended). (ii) Unless the LC Issuer and the Borrower otherwise agree, when a Letter of Credit is issued, it shall be subject to the version of the Uniform Customs and Practice for Documentary Credits in effect at the time of issuance (UCP), or International Standby Practices 1998 (ISP98), at the LC Issuer’s discretion. If such Letter of Credit includes any provision that does not conform to standard Letter of Credit practice, all provisions of this Agreement, including without limitation those relating to reimbursement and indemnification, shall apply to such Letter of Credit. (iii) Notwithstanding anything to the contrary set forth in this Agreement, at the request of the Borrower, a Letter of Credit issued hereunder may contain a statement to the effect that such Letter of Credit is issued for the account of the Servicer or an Affiliate of the Servicer; provided that notwithstanding such statement, the Borrower shall be the actual account party for all purposes of this Agreement for such Letter of Credit, and such statement shall not affect the Borrower’s reimbursement obligations hereunder with respect to such Letter of Credit. (c) Notice of Letter of Credit Request. The Administrative Agent shall promptly notify the LC Issuer and each Committed Lender of the request by the Borrower for a Letter of Credit hereunder. (d) Participations. Immediately upon the issuance by the LC Issuer of any Letter of Credit (or any Modification of a Letter of Credit increasing the amount thereof), the LC Issuer shall be deemed to have sold and transferred to each Committed Lender, and each Committed Lender shall be deemed irrevocably and unconditionally to have purchased and received from the LC Issuer, without recourse or warranty, an undivided interest and participation, to the extent of such Committed Lender’s Ratable Share, in such Letter of Credit, each drawing made thereunder and the obligations of the Borrower hereunder with respect thereto, and any security therefor or guaranty pertaining thereto. Upon any change in the Commitments or Ratable Shares of the Committed Lenders pursuant to this Agreement, it is hereby agreed that, with respect to all outstanding Letters of Credit and unreimbursed drawings thereunder, there shall be an automatic adjustment to the participations pursuant to this Section 2.7(d) to reflect the new Ratable Shares of the assignor and assignee Committed Lender or of all Committed Lenders with Commitments, as the case may be. The Committed Lenders or their Groups will satisfy their funding obligations under this Section 2.7(d) by funding LC Loans pursuant to Section 2.8(a). Section 2.8 Disbursements, Reimbursements and LC Advances. (a) Notice of Drawings; Reimbursement by the Borrower; LC Advances. In the event of any drawing under a Letter of Credit by the beneficiary or transferee thereof that the LC Issuer determines it is legally obligated to honor, the LC Issuer will promptly notify the Borrower and each Co-Agent of such drawing by written notice in the form of Exhibit 2.8(a)-1 (each, a “Draw Notice”). The Borrower

shall reimburse the LC Issuer not later than 10:00 a.m. (New York City time) on the Business Day following its receipt of a Draw Notice (such next Business Day, the “Reimbursement Date”) in an amount equal to the amount so paid by the LC Issuer. In the event the Borrower fails to reimburse the LC Issuer for the full amount of any drawing under a Letter of Credit by 10:00 a.m. (New York City time) on the Reimbursement Date, the Borrower will be deemed to have requested that an Advance be made on the Business Day following the applicable Reimbursement Date in a Principal amount equal to such LC Reimbursement Obligation (each such Advance, an “LC Advance”) regardless of whether the Commitment Expiry Date or Termination Date has previously occurred, and the LC Issuer will promptly notify each Co-Agent of such deemed request in writing in the form of Exhibit 2.8(a)-2 hereto (each, an “LC Advance Notice”). (b) LC Advances. Upon receipt of an LC Advance Notice, each applicable Co-Agent shall determine whether its Conduit will fund an LC Loan in an amount equal to the portion of the LC Advance specified in such LC Advance Notice, andPNC severally agrees to make an LC Loan in an amount equal to its Group’s Commitment Percentage of the specified the LC Reimbursement Obligation, on the terms and subject to the conditions hereof, provided that at no time may the aggregate Principal amount of PNC’s Credit Exposure at any one time outstanding exceed the PNC Allocation Limit; (ii) in the event that Gotham elects not to make an LC Loan in an amount equal to its Group’s Commitment Percentage of the specified the LC Reimbursement Obligation, the Gotham Agent shall promptly notify the Borrower and each of the Liquidity Banks in the Gotham Group, and each of such Liquidity Banks severally agrees to make its Pro Rata Share of such LC 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’ Credit Exposure at any one time outstanding exceed the Gotham Allocation Limit; and (iii) in the event that Atlantic elects not to make an LC Loan in an amount equal to its Group’s Commitment Percentage of the specified the LC Reimbursement Obligation, the Atlantic Agent shall promptly notify the Borrower and each of the Liquidity Banks in the Atlantic Group, and each of such Liquidity Banks severally agrees to make its Pro Rata Share of such LC 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’ Credit Exposure at any one time outstanding exceed the Atlantic Allocation Limit. Notwithstanding the fact that LC Loans are being made to the Borrower, all LC Loans shall be disbursed directly to the LC Issuer for application to the specified LC Reimbursement Obligation on the Borrower’s behalf. If any Group fails to make available to the LC Issuer its LC Loan(s) by 10:00am (NY time) on the Business Day after the Reimbursement Date, then Interest shall accrue on the deficient amount from the Reimbursement Date to the date on which such Group fully-funds its LC Loan(s) (i) at a rate per annum equal to the Federal Funds Rate during the first three days following the Reimbursement Date and (ii) at a rate per annum equal to the rate applicable to PNC’s Loans on and after the fourth day following the Reimbursement Date. Each Committed ▇▇▇▇▇▇’s obligation to reimburse the LC Issuer for such Committed ▇▇▇▇▇▇’s Ratable Share of any drawing under a Letter of Credit issued in accordance with this Agreement shall continue until the last to occur of any of the following events: (A) the occurrence of the Commitment Expiry Date or the LC Issuer otherwise ceases to be obligated to issue or cause to be issued Letters of Credit hereunder; (B) no Letter of Credit issued hereunder remains

outstanding and effective; or (C) all Persons (other than the Borrower) have been fully reimbursed for all payments made under or relating to Letters of Credit.

(a) The Borrower promises to pay the LC Obligations, together with all LC Fees, LC Fronting Fees and, if applicable, Interest thereon, in accordance with the terms of the Fee Letter and this Section 2.9. (b) Upon receipt by the LC Issuer for its account of immediately available funds from or for the account of the Borrower in excess of PNC’s LC Sublimit Percentage thereof, the LC Issuer shall promptly distribute any excess to the other Co-Agents. (c) If the LC Issuer is required at any time to return to the Borrower, or to a trustee, receiver, liquidator, custodian, or any official in any insolvency proceeding, any portion of the payments made by the Borrower to the LC Issuer pursuant to this Agreement in reimbursement of a payment made under the Letter of Credit or Interest or fee thereon, each Committed Lender shall, on demand of the LC Issuer, forthwith return to the LC Issuer the amount of its Ratable Share of any amounts so returned by the LC Issuer plus Interest at the Federal Funds Rate, from the date the payment was first made to such Committed Lender through, but not including, the date the payment is returned by such Committed Lender. (d) If any Letters of Credit are outstanding and undrawn on the Termination Date, the LC Collateral Account shall be funded from Collections (or by other funds available to the Borrower) in an amount equal to the sum of the Outstanding Face Amount of such Letters of Credit plus Expected LC Fees. (e) Funds in the LC Collateral Account will be used to reimburse the LC Issuer and (to the extent they have unreimbursed LC Advances) the applicable Lenders for due and payable fees related to the Letters of Credit and for any draws on the Letters of Credit and LC Advances which have not reimbursed by the Borrower or repaid from Collections. Any funds on deposit in the ▇▇ ▇▇▇▇ Collateral Account after all Letters of Credit have expired or have been terminated in accordance with their respective terms, all draws on the Letters of Credit have been reimbursed, all LC Advances have been repaid, all fees due and payable with respect to the Letters of Credit have been paid in full, and the Aggregate Commitment has been terminated, shall be remitted to the Borrower.

Section 2.10 Documentation and LC Processing Fees. The Borrower agrees to be bound by the terms of the LC Application, by the LC Issuer’s commercially reasonable interpretation of any Letter of Credit issued for the Borrower and by the LC Issuer’s customary practices relating to Letters of Credit, though the LC Issuer’s interpretation of such practices may be different from the Borrower’s own. In the event of a conflict between the LC Application and this Agreement, this Agreement shall govern. It is understood and agreed that, except in the case of gross negligence or willful misconduct by the LC Issuer, the LC Issuer shall not be liable for any error, negligence and/or mistakes, whether of omission or commission, in following the Borrower’s instructions or those contained in the Letters of Credit or any modifications, amendments or supplements thereto. In addition to any other fees or expenses owing under the Fee Letter or any other Transaction Documents or otherwise pursuant to any LC Application, the Borrower shall pay to the LC Issuer for its own account any LC Processing Fees. LC Processing Fees shall be due and payable upon demand and shall be nonrefundable. Section 2.11 Determination to Honor Drawing Request. In determining whether to honor any request for drawing under any Letter of Credit by the beneficiary thereof, the LC Issuer shall be responsible only to determine that the documents and certificates required to be delivered under such Letter of Credit have been delivered and that they comply on their face with the requirements of such Letter of Credit and that any other drawing condition appearing on the face of such Letter of Credit has been satisfied in the manner so set forth. Section 2.12 Nature of Participation and LC Reimbursement Obligations. Each Committed Lender’s obligation in accordance with this Agreement to make LC Loans as a result of an unreimbursed drawing under a Letter of Credit, and the obligations of the Borrower to reimburse the LC Issuer upon a draw under a Letter of Credit, shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Article II under all circumstances, including the following circumstances: (i) any set-off, counterclaim, recoupment, defense or other right which such Committed Lender may have against the LC Issuer, the Administrative Agent, the Co-Agents, the Lenders, the Borrower or any other Person for any reason whatsoever; (ii) the failure of the Borrower or any other Person to comply with the conditions set forth in this Agreement for the making of a purchase, reinvestments, requests for Letters of Credit or otherwise, it being acknowledged that such conditions are not required for the making of LC Advances hereunder; (iii) any lack of validity or enforceability of any Letter of Credit or any set-off, counterclaim, recoupment, defense or other right which Borrower, an Originator or any Affiliate thereof on behalf of which a Letter of Credit has been issued may have against the LC Issuer, the Administrative Agent, any Lender, any Co-Agent or any other Person for any reason whatsoever; (iv) any claim of breach of warranty that might be made by the Borrower, the LC Issuer or any Committed Lender against the beneficiary of a Letter of Credit, or the existence of any claim, set-off, defense or other right which the Borrower, the LC Issuer or any Committed Lender may have at any time against a beneficiary, any successor beneficiary or any transferee of any Letter of Credit or the proceeds thereof (or any Persons for whom any such transferee may be acting), the LC Issuer, any Committed Lender, the Administrative Agent, any Lender or any Co-Agent or any other Person, whether in connection with this Agreement, the transactions contemplated herein or any

unrelated transaction (including any underlying transaction between the Borrower or any Subsidiaries of the Borrower or any Affiliates of the Borrower and the beneficiary for which any Letter of Credit was procured); (v) except if the LC Issuer shall have actual knowledge to the contrary: (A) the lack of power or authority of any signer of, or lack of validity, sufficiency, accuracy, enforceability or genuineness of, any draft, demand, instrument, certificate or other document presented under any Letter of Credit, or (B) any such draft, demand, instrument, certificate or other document proving to be forged, fraudulent, invalid, defective or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; (vi) payment by the LC Issuer under any Letter of Credit against presentation of a demand, draft or certificate or other document which does not strictly comply with the terms of such Letter of Credit other than as a result of the gross negligence or willful misconduct of the LC Issuer; (vii) the solvency of, or any acts or omissions by, any beneficiary of any Letter of Credit, or any other Person having a role in any transaction or obligation relating to a Letter of Credit, or the existence, nature, quality, quantity, condition, value or other characteristic of any property or services relating to a Letter of Credit; (viii) any failure by the LC Issuer or any of the LC Issuer’s Affiliates to issue any Letter of Credit in the form requested by the Borrower, unless the LC Issuer has received written notice from the Borrower of such failure within five (5) Business Days after the LC Issuer shall have furnished the Borrower a copy of such Letter of Credit and such error is material and no drawing has been made thereon prior to receipt of such notice; (ix) any Material Adverse Effect; (x) any breach of this Agreement or any Transaction Document by any party thereto; (xi) the occurrence or continuance of an Event of Bankruptcy with respect to the Borrower, any Originator or the Servicer; (xii) the fact that an Event of Default or an Unmatured Default shall have occurred and be continuing; (xiii) the fact that this Agreement or the obligations of the Borrower or Servicer hereunder shall have been terminated; and (xiv) any other circumstances or happening whatsoever, whether or not similar to any of the foregoing, that might otherwise constitute a suretyship defense. Nothing contained in this Section 2.12 shall be deemed to relieve the LC Issuer or the Administrative Agent from any claim by the Borrower for the gross negligence or willful misconduct of the LC Issuer in respect of honoring or failing to honor any drawing under any Letter of Credit or otherwise in respect of any Letter of Credit, but any such claim may not be used as a defense to the Borrower’s obligation to reimburse the LC Issuer for such drawing.

Section 2.13 Liability for Acts and Omissions. As between the Borrower, on the one hand, and the Administrative Agent, the LC Issuer, the Co-Agents and the Lenders, on the other, the Borrower assumes all risks of the acts and omissions of, or misuse of any Letter of Credit by, the respective beneficiaries of such Letter of Credit. In furtherance and not in limitation of the foregoing, none of the Administrative Agent, the LC Issuer, the Co-Agents or the Lenders shall be responsible for: (i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for an issuance of any such Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged (even if the LC Issuer or any Committed Lender shall have been notified thereof); (ii) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any such Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) the failure of the beneficiary of any such Letter of Credit, or any other party to which such Letter of Credit may be transferred, to comply fully with any conditions required in order to draw upon such Letter of Credit or any other claim of the Borrower against any beneficiary of such Letter of Credit, or any such transferee, or any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any such transferee; (iv) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, electronic mail, cable, telegraph, telex, facsimile or otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under any such Letter of Credit or of the proceeds thereof; (vii) the misapplication by the beneficiary of any such Letter of Credit of the proceeds of any drawing under such Letter of Credit; or (viii) any consequences arising from causes beyond the control of the Administrative Agent, the LC Issuer, the Committed Lenders, the Co-Agents and the Lenders, including any Governmental Acts, and none of the above shall affect or impair, or prevent the vesting of, any of the LC Issuer’s rights or powers hereunder. Nothing contained in the preceding sentence shall relieve the LC Issuer, the Administrative Agent, the Co-Agents or any Lender for such party’s gross negligence, willful misconduct or bad faith (as determined by a court of competent jurisdiction in a final non-appealable judgment) in connection with the actions or omissions described in clauses (i) through (viii) of such sentence, but in no event shall the Administrative Agent, the LC Issuer, the Committed Lenders, the Co-Agents or the Lenders or their respective Affiliates, be liable to the Borrower or any other Person for any indirect, consequential, incidental, punitive, exemplary or special damages or expenses (including without limitation attorneys’ fees), or for any damages resulting from any change in the value of any property relating to a Letter of Credit. Without limiting the generality of the foregoing, the Administrative Agent, the LC Issuer, the Committed Lenders, the Co-Agents and the Lenders and each of its Affiliates (i) may rely on any written communication believed in good faith by such Person to have been authorized or given by or on behalf of the applicant for a Letter of Credit; (ii) may honor any presentation if the documents presented appear on their face to comply with the terms and conditions of the relevant Letter of Credit; (iii) may honor a previously dishonored presentation under a Letter of Credit, whether such dishonor was pursuant to a court order, to settle or compromise any claim of wrongful dishonor, or otherwise, and shall be entitled to reimbursement to the same extent as if such presentation had initially been honored, together with any Interest paid by the LC Issuer or its Affiliates; (iv) may honor any drawing that is payable upon presentation of a statement advising negotiation or payment, upon receipt of such statement (even if such statement indicates that a draft or other document is being delivered separately), and shall not be liable for any failure of any such draft or other document to arrive, or to conform in any way with the relevant Letter of Credit; (v) may pay any paying or negotiating bank

claiming that it rightfully honored under the laws or practices of the place where such bank is located; and (vi) may settle or adjust any claim or demand made on the Administrative Agent, the LC Issuer, the Committed Lenders, the Co-Agents or the Lenders or their respective Affiliates, in any way related to any order issued at the applicant’s request to an air carrier, a letter of guarantee or of indemnity issued to a carrier or any similar document (each, an “Order”) and may honor any drawing in connection with any Letter of Credit that is the subject of such Order, notwithstanding that any drafts or other documents presented in connection with such Letter of Credit fail to conform in any way with such Letter of Credit. In furtherance and extension and not in limitation of the specific provisions set forth above, any action taken or omitted by the LC Issuer under or in connection with any Letter of Credit issued by it or any documents and certificates delivered thereunder, if taken or omitted in good faith and without gross negligence or willful misconduct, as determined by a final non-appealable judgment of a court of competent jurisdiction, shall not put the LC Issuer under any resulting liability to the Borrower, any Committed Lender or any other Person. Section 2.14 Intended Tax Treatment. All parties to this Agreement covenant and agree to treat any Advance and any drawing on a Letter of Credit under this Agreement as debt for all U.S. federal income tax purposes and to not take any position on any tax return inconsistent with the foregoing, except as otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Code (or any comparable provision of any state, local or foreign law). ARTICLE III. SETTLEMENTS Section 3.1 Reporting. (a) Monthly Reports. Not later than the Monthly Reporting Date in each calendar month hereafter, the Servicer shall deliver to each of the Co-Agents, a Monthly Report accompanied by an electronic file in a form reasonably satisfactory to each of the Co-Agents; provided, however, that if an Unmatured Default or an Event of Default shall exist and be continuing, each of the Co-Agents may request that a computation of the Borrowing Base also be made on a date that is not a Monthly Reporting Date and, so long as such request is not made on or within 5 Business Days prior to the last day of any calendar month, the Servicer agrees to provide such computation within 3 Business Days after such request. (b) Weekly Reports; Right to Request Cash Collateral Payment[Reserved]. Upon written request of the Administrative Agent, not later than each Weekly Reporting Date occurring at least 14 days after the Servicer’s receipt of such request and continuing until the Administrative Agent gives written notice that it no longer desires Weekly Reports, the Servicer shall deliver to each of the Co-Agents, a Weekly Report of the dollar amount of cash collections and the number of requisitions, in each case, for the second preceding week (the “Report Week”). If the dollar amount of cash Collections or the number of requisitions for the Report Week is less than 50% of the arithmetic average of the corresponding figures for the four immediately preceding Report Weeks, upon request of any of the Co-Agents, the Servicer shall provide a written computation of the Cash Collateral Payment within 3 Business Days after such request.

. (c) Interest; Other Amounts Due.

Section 3.2 Turnover of Collections; Pre-Termination Waterfall. Without limiting any Agent’s or ▇▇▇▇▇▇’s recourse to the Borrower for payment of any and all Obligations: (a) If any Monthly Report reveals that a mandatory prepayment or Cash Collateral Payment is required under Section 1.5(b), (c), (d) or (e), not later than the 1:00 p.m. (New York City time) on the next succeeding Settlement Date, the Servicer shall turn over to each applicable Co-Agent, for distribution to its Constituents, a portion of the Collections equal to the amount of such required mandatory prepayment and shall turn over to the LC Issuer for deposit into the LC Collateral Account a portion of the Collections equal to the amount of such required Cash Collateral. (b) If, on any Settlement Date, any Loans are to be voluntarily prepaid in accordance with Section 1.5(a), or if the aggregate Principal amount of the Advances outstanding is to be reduced, the Servicer shall turn over to each of the Co-Agents, for distribution to its Constituents, a portion of the Collections equal to the Groups’ respective Percentages of the aggregate amount of such voluntary prepayment or reduction. (c) In addition to, but without duplication of, the foregoing, on (i) each Settlement Date and (ii) each other date on which any Principal of or Interest on any of the Obligations becomes due (whether by acceleration or otherwise) and, in the case of Principal, has not been reborrowed pursuant to Section 1.1 (if permitted), the Servicer shall turn over to each of the Co-Agents, for distribution to their respective Constituents, the Groups’ respective Percentages of a portion of the Collections equal to the aggregate amount of all other Obligations that are due and owing on such date.

(d) If the aggregate amount of Collections and payments on Demand Advances received by the Co-Agents on any Settlement Date are insufficient to pay all Required Amounts, the aggregate amount received shall be applied to the items specified in the subclauses below, in the order of priority of such subclauses:

(i) to any accrued and unpaid Interest on the Loans that is then due and owing, including any previously accrued Interest which was not paid on its applicable due date; (ii) if the Servicer is not the Borrower or an Affiliate thereof, to any accrued and unpaid Servicer’s Fee that is then due and owing to such Servicer, together with any invoiced expenses of the Servicer due and owing pursuant to Section 8.1(d); (iii) to the Unused Fee and the Usage Fee accrued during such Accrual Period, plus any previously accrued Unused Fee and Usage Fee not paid on a prior Settlement Date; (iv) ratably to the payment of the Principal of any Loans that are then due and owing and to the Cash Collateralization of any Non-Renewing Lender’s Share of the LC Obligations; (v) to the payment of LC Processing Fees that are then due and owing. (vi) to other Obligations that are then due and owing; (vii) if the Servicer is the Borrower, Quest Diagnostics or one of their respective Affiliates, to the accrued and unpaid Servicer’s Fee; and (viii) the balance, if any, to the Borrower. (e) If the Servicer is ever required to deliver a computation of the Cash Collateral Payment pursuant to Section 3.1(b), not later than one (1) Business Day after delivery of such computation, the Borrower shall pay to the applicable Co-Agent an amount equal to its Group’s Percentage of the Cash Collateral Payment to be invested in Permitted Investments selected by such Co-Agent but held as Collateral for the Obligations until the next Settlement Date pending distribution in accordance with Section 3.2(d). If the Borrower lacks sufficient funds to make any such Cash Collateral Payment, in whole or in part, the Borrower shall make immediate demand upon Quest Diagnostics for payment of any Demand Advances that are then outstanding, and, upon receipt of any such shortfall amount, the Borrower shall pay each Group’s Percentage of such shortfall amount to the applicable Co-Agent for deposit into a cash collateral account to be invested in Permitted Investments selected by the applicable Co-Agent but held as Collateral for the Obligations until the next Settlement Date pending distribution in accordance with Section 3.2(d). All payments of Principal and Interest made to the Atlantic Group Agent for the account of any Tranched Loan Lender shall be allocated by such Tranched Loan Lender in accordance with Annex C to this Agreement. (f) In addition to, but without duplication of, the foregoing, on (i) each Settlement Date and (ii) each other date on which any Principal of or Interest on any of the Loans becomes due (whether by acceleration pursuant to Section 10.2(a) or 10.2(b) or otherwise), the Servicer shall turn over to each of the Co-Agents, for distribution to the Lenders, a portion of the Collections equal to the aggregate amount of all Obligations that are due and owing on such date.

Section 3.3 Non-Distribution of Servicer’s Fee. Each of the Agents and the other Secured Parties hereby consents to the retention by the Servicer of a portion of the Collections equal to the Servicer’s Fee (and, if applicable, any invoiced expenses of such Servicer that are due and owing pursuant to Section 8.1(d)) so long as the Collections received by the Servicer are sufficient to pay all amounts pursuant to Section 3.2 of a higher priority as specified in such Section. Section 3.4 Deemed Collections. If as of the last day of any Accrual Period: (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: (i) as a result of any rejected services, any cash discount or any other adjustment by the applicable Originator or any Affiliate thereof (regardless of whether the same is treated by such Originator or Affiliate as a write-off), or as a result of any surcharge or other governmental or regulatory action, or (ii) as a result of any setoff or breach of the underlying agreement in respect of any claim by the Obligor thereof (whether such claim arises out of the same or a related or an unrelated transaction), or (iii) on account of the obligation of the applicable Originator or any Affiliate thereof to pay to the related Obligor any rebate or refund, or (iv) the Unpaid Net Balance of any Receivable is less than the amount included in calculating the Net Pool Balance for purposes of any Monthly Report (for any reason other than such Receivable becoming a Defaulted Receivable), or (b) any of the representations or warranties of the Borrower set forth in Section 6.1(j), (l) or (p) was not true when made with respect to any Receivable, or any of the representations or warranties of the Borrower set forth in Section 6.1(l) is no longer true with respect to any Receivable, then, in such event, the Borrower shall be deemed to have received a Collection in an amount equal to (A) the amount of such reduction, cancellation or overstatement, in the case of the preceding clauses (a)(i), (a)(ii), (a)(iii) and (a)(iv), and (B) in the full amount of the Unpaid Net Balance of such Receivable in the case of the preceding clause (b).

Section 3.5 Release of Excess Cash Collateral. If on any Settlement Date, the balance in the LC Collateral Account exceeds the amount required, unless an Event of Default or an Unmatured Default Event shall exist and be continuing, the LC Issuer shall release the excess cash collateral to the Borrower.

Quest Diagnostics or the Borrower, as applicable, shall pay to each of the Agents, the LC Issuer and the Lenders certain fees from time to time in amounts and payable on such dates as are set forth in the Fee Letter. Section 4.2 Yield Protection. (a) If any Regulatory Change occurring after the date hereof: (i) shall subject an Affected Party to any Tax, duty or other charge with respect to its Obligations or, as applicable, its Commitment or its Liquidity Commitment, payments to the Affected Party of any Obligations, owed to or funded in whole or in part by it or any other amounts due under this Agreement in respect of its Obligations or, as applicable, its Commitment or its Liquidity Commitment except, in each case, for Taxes other than capital taxes imposed on such Affected Party’s loans, loan principal, Letters of Credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or (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 (iii) shall affect the amount of capital required or expected to be maintained by any Affected Party; or (iv) shall impose any other condition affecting any Obligation owned or funded in whole or in part by any Affected Party, or its rights or obligations, if any, to make Loans or Liquidity Fundings or to issue or participate in Letters of Credit; or (v) shall change the rate for, or the manner in which the Federal Deposit Insurance Corporation (or a successor thereto) assesses deposit insurance premiums or similar charges; or (vi) shall require any Conduit to be consolidated for financial accounting purposes with any other Person; and the result of any of the foregoing is or would be: (x) to increase the cost to or to impose a cost on (I) an Affected Party funding or making or maintaining any Loan, any Liquidity Funding, any Letter of Credit or participation therein, or any commitment of such Affected Party with respect to any of the foregoing, or (II) the LC Issuer, any of

the Agents for continuing its or the Borrower’s relationship with any Affected Party, in each case, in an amount deemed to be material by such Affected Party, (y) to reduce the amount of any sum received or receivable by an Affected Party under this Agreement or under the Liquidity Agreement, or (z) to reduce the rate of return on such Affected Party’s capital as a consequence of its Commitment, its Liquidity Commitment, the Letters of Credit or such Affected Party’s participation therein, or the Loans made by it to a level below that which such Affected Party could have achieved but for the occurrence of such circumstances, then, within thirty days after demand by such Affected Party (which demand shall be made not more than 90 days after the date on which the Affected Party obtains actual knowledge of such Regulatory Change and shall be accompanied by a certificate setting forth, in reasonable detail, the basis of such demand and the methodology for calculating, and the calculation of, the amounts claimed by the Affected Party), the Borrower shall pay directly to such Affected Party such additional amount or amounts as will compensate such Affected Party for such actual additional cost, actual increased cost or actual reduction. (b) Each Affected Party will promptly notify the Borrower, the Administrative Agent, the LC Issuer 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. Any Affected Party when making a claim under this Section 4.2 shall submit to the Borrower the above-referenced certificate as to such actual increased cost or actual reduced return (including calculation thereof in reasonable detail), which statement shall, in the absence of demonstrable error, be conclusive and binding upon the Borrower. (d) Each of the Lenders agrees, and shall require each Affected Party to agree that, with reasonable promptness after an officer of such Lender or such Affected Party responsible for administering the Transaction Documents becomes aware that it (x) has become an Affected Party under this Section 4.2, (y) is entitled to receive payments under this Section 4.2, or (z) is or has become subject to U.S. withholding Taxes payable by any Loan Party in respect of its investment hereunder, it will, to the extent not inconsistent with any internal policy of such Person or any applicable legal or regulatory restriction, (i) use all reasonable efforts to make, fund or maintain its commitment or investment hereunder through another branch or office of such Affected Party, or (ii) take such other reasonable measures, if, as a result thereof, the circumstances which would cause such Person to be an Affected Party under this Section 4.2 would cease to exist, or the additional amounts which would otherwise be required to be paid to such Person pursuant to this Section 4.2 would be reduced, or such withholding Taxes would be reduced, and if the making, funding or maintaining of such commitment or investment through such other office or in accordance with such

other measures, as the case may be, would not otherwise adversely affect such commitment or investment or the interests of such Person; provided that such Person will not be obligated to utilize such other lending office pursuant to this Section 4.2 unless the Borrower agrees to pay all incremental out-of-pocket expenses incurred by such Person as a result of utilizing such other office as described in clause (i) above. (e) If any Lender makes a claim for compensation under this Section 4.2, the Borrower may propose an Eligible Assignee to the applicable Co-Agent who is willing to accept an assignment of such ▇▇▇▇▇▇’s Commitment, Liquidity Commitment, outstanding Loans and interests in the Letters of Credit, as applicable, together with each of its other rights and obligations under the Transaction Documents; provided that any expenses or other amounts which would be owing to such Lender pursuant to any indemnification provision hereof (including, if applicable, Section 4.3) shall be payable by the Borrower as if the Borrower had prepaid the Loans of the assigning Lenders rather than such assigning ▇▇▇▇▇▇▇ having assigned their respective interests hereunder. 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 all 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 Daily Term SOFR 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. Section 4.4 Inability to Determine Rates. Subject to Section 4.6, if, prior to the first day of any Interest Period for any Term SOFR Loan or on any day for any Daily Term SOFR Loan: (i) any applicable Co-Agent determines (which determination shall be conclusive and binding absent manifest error) that “Term SOFR,” “Daily One Month Term SOFR” or “Daily Three Month Term SOFR,” as applicable, cannot be determined pursuant to the applicable definition thereof, or (ii) any applicable Co-Agent determines that for any reason in connection with (x) any request for a Term SOFR Loan or a Daily Term SOFR Loan or a conversion thereto or a continuation thereof or (y) the maintenance of a Daily Term SOFR Loan, that Adjusted Term SOFR for any requested Interest Period with respect to a proposed Term SOFR Loan or the applicable Daily Term SOFR for any day with respect to a Daily Term SOFR Loan does not adequately and fairly reflect the cost to the applicable Lender(s) in its Group of funding such Term SOFR Loan or Daily Term SOFR Loan or maintaining such Daily Term SOFR Loan, as applicable, and such Co-Agent has provided notice of such determination to the Administrative Agent, the Administrative Agent will promptly so notify the Borrower and each Co-Agent. Upon notice thereof by the Administrative Agent to the Borrower, any obligation of the Lenders in such Group to make Term SOFR Loans or to make or maintain Daily Term SOFR Loans, as applicable, and any right of the Borrower to continue Term SOFR Loans or Daily Term SOFR Loans or to convert Alternate Base Rate Loans to Term SOFR Loans or Daily Term SOFR Loans, shall be suspended (to the extent of the affected Term SOFR Loans or affected Interest Periods or affected Daily Term SOFR Loans, as applicable) until the Administrative Agent (with respect to clause (ii), at the instruction of the applicable Co-Agent) revokes such notice. Upon receipt of such notice, (i) the Borrower may revoke any pending request for a borrowing of, conversion to or continuation of Term SOFR Loans or Daily Term SOFR Loans (to the extent of the affected Term SOFR Loans or affected Interest Periods or affected Daily Term SOFR Loans) or, failing that, the Borrower will be deemed to have converted any such request into a request for a Borrowing of or conversion to Alternate Base Rate Loans in the amount specified therein and (ii) any

outstanding affected Term SOFR Loans and Daily Term SOFR Loans, as applicable, will be deemed to have been converted into Alternate Base Rate Loans at the end of the applicable Interest Period, in the case of affected Term SOFR Loans, or immediately, in the case of affected Daily Term SOFR Loans. Upon any such conversion, the Borrower shall also pay accrued interest on the amount so converted, together with any additional amounts required pursuant to Section 4.3. Subject to Section 4.6, if an applicable Co-Agent determines (which determination shall be conclusive and binding absent manifest error) that “Term SOFR” cannot be determined pursuant to the definition thereof on any given day, the interest rate on Alternate Base Rate Loans shall be determined by the Administrative Agent without reference to clause (c) of the definition of “Alternate Base Rate” until the Administrative Agent revokes such determination. Section 4.5 Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable lending office to make, maintain or fund Loans whose interest is determined by reference to SOFR, the Term SOFR Reference Rate, Term SOFR, Daily One Month Term SOFR or Daily Three Month Term SOFR (each such Loan, a “SOFR Loan”), or to determine or charge interest rates based upon SOFR, the Term SOFR Reference Rate, Term SOFR, Daily One Month Term SOFR or Daily Three Month Term SOFR, then, upon notice thereof by such Lender to the Borrower (through such Lender’s Co-Agent), (a) any obligation of such Lender to make or maintain a SOFR Loan, and any right of the Borrower to continue SOFR Loans or to convert Alternate Base Rate Loans to SOFR Loans, shall be suspended, and (b) the Alternate Base Rate shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to clause (c) of the definition of “Alternate Base Rate”, in each case until such Lender notifies the Agents and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, (i) the Borrower shall, if necessary to avoid such illegality, upon demand from any Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all SOFR Loans to Alternate Base Rate Loans (and the Alternate Base Rate shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to clause (c) of the definition of “Alternate Base Rate”), on the last day of the Interest Period therefor with respect to Term SOFR Loans, if all affected Lenders may lawfully continue to maintain such Term SOFR Loans to such day, or immediately, in the case of Daily Term SOFR Loans or if any Lender may not lawfully continue to maintain such Term SOFR Loans to such day, and (ii) if necessary to avoid such illegality, the Administrative Agent shall during the period of such suspension compute the Alternate Base Rate without reference to clause (c) of the definition of “Alternate Base Rate,” in each case until the Administrative Agent is advised in writing by each affected Lender or its Co-Agent that it is no longer illegal for such Lender to determine or charge interest rates based upon SOFR, the Term SOFR Reference Rate, Term SOFR, Daily One Month Term SOFR or Daily Three Month Term SOFR. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted, together with any additional amounts required pursuant to Section 4.3. Section 4.6 Benchmark Setting. (a) Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Transaction Document, upon the occurrence of a Benchmark Transition Event, the Administrative Agent (after consultation with the Co-Agents) and the Borrower may amend this Agreement to replace the then-current Benchmark with a Benchmark Replacement. Any such amendment with respect to a Benchmark Transition Event will become effective at 5:00 p.m. (New York City time) on the fifth (5th) Business Day after the Administrative Agent has posted such proposed amendment to all Co-Agents and the Borrower so long as the Administrative Agent has not

received, by such time, written notice of objection to such amendment from any Co-Agent. No replacement of a Benchmark with a Benchmark Replacement pursuant to this Section 4.6(a) will occur prior to the applicable Benchmark Transition Start Date. (b) Benchmark Replacement Conforming Changes. In connection with the use, administration, adoption or implementation of a Benchmark Replacement, the Administrative Agent will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Transaction Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Transaction Document. (c) Notices; Standards for Decisions and Determinations. The Administrative Agent will promptly notify the Borrower and the Lenders of (i) the implementation of any Benchmark Replacement and (ii) the effectiveness of any Conforming Changes in connection with the use, administration, adoption or implementation of a Benchmark Replacement. The Administrative Agent will promptly notify the Borrower of the removal or reinstatement of any tenor of a Benchmark pursuant to Section 4.6(d). Any determination, decision or election that may be made by the Administrative Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 4.6, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement or any other Transaction Document, except, in each case, as expressly required pursuant to this Section 4.6. (d) Unavailability of Tenor of Benchmark. Notwithstanding anything to the contrary herein or in any other Transaction Document, at any time (including in connection with the implementation of a Benchmark Replacement), (i) if the then-current Benchmark is a term rate (including the Term SOFR Reference Rate) and either (A) any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the Administrative Agent in its reasonable discretion or (B) the administrator of such Benchmark or the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is not or will not be representative or in compliance with or aligned with the International Organization of Securities Commissions (IOSCO) Principles for Financial Benchmarks, then the Administrative Agent may modify the definition of “Interest Period”, “Daily One Month Term SOFR” or “Daily Three Month Term SOFR” (or any similar or analogous definition) for any Benchmark settings at or after such time to remove such unavailable, non-representative, non-compliant or non-aligned tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (B) is not, or is no longer, subject to an announcement that it is not or will not be representative or in compliance with or aligned with the International Organization of Securities Commissions (IOSCO) Principles for Financial Benchmarks for a Benchmark (including a Benchmark Replacement), then the Administrative Agent (in consultation with the Borrower) may modify the definition of “Interest Period”, “Daily One Month Term SOFR” or “Daily Three Month Term SOFR” (or any similar or analogous definition) for all Benchmark settings at or after such time to reinstate such previously removed tenor. (e) Benchmark Unavailability Period. Upon the Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrower may revoke any pending request

for a borrowing of, conversion to or continuation of SOFR Loans to be made, converted or continued during any Benchmark Unavailability Period and, failing that, the Borrower will be deemed to have converted any such request into a request for a borrowing of or conversion to Alternate Base Rate Loans. For the avoidance of doubt, upon the commencement of a Benchmark Unavailability Period, all outstanding Daily Term SOFR Loans shall be automatically and immediately converted to Alternate Base Rate Loans. During a Benchmark Unavailability Period or at any time that a tenor for the then-current Benchmark is not an Available Tenor, the component of the Alternate Base Rate based upon the then-current Benchmark or such tenor for such Benchmark, as applicable, will not be used in any determination of the Alternate Base Rate. ARTICLE V. CONDITIONS PRECEDENT Section 5.1 [Intentionally Deleted]. Section 5.2 Conditions Precedent to All Credit Events. Each Credit Event (including the initial Credit Event under this Agreement but excluding the funding of an LC Advance) shall be subject to the conditions precedent that on the applicable Borrowing Date, each of the following statements shall be true (and the Borrower, by accepting the proceeds of any Advance comprising such Credit Event, and each other Loan Party, upon such acceptance by the Borrower, shall be deemed to have certified that): (a) the representations and warranties contained in Section 6.1 are correct in all respects on and as of the date of such Advance as though made on and as of such day and shall be deemed to have been made on such day (except for such representations which speak only as of an earlier date), (b) no event has occurred and is continuing, or would result from such Advance, that constitutes an Event of Default or Unmatured Default, (c) the Termination Date shall not have occurred, (d) if such Advance is to be funded, in whole or in part, by any Conduit’s Liquidity Banks, such Conduit shall have Liquidity Banks in its Group with sufficient undrawn Commitments in an aggregate amount sufficient to fund the requisite portion of such Advance, and (e) each of the Co-Agents shall have received (with such receipt to be determined in accordance with Section 14.2 of this Agreement) a timely Borrowing Request in accordance with Section 2.1; provided, however, the absence of the occurrence and continuance of an Unmatured Default shall not be a condition precedent to any Advance which does not increase the aggregate Principal amount of all Advances outstanding over the aggregate outstanding Principal balance of the Advances as of the opening of business on such day.

ARTICLE VI. REPRESENTATIONS AND WARRANTIES Section 6.1 Representations and Warranties of Loan Parties.

(i) Financial Statements and Absence of Certain Material Adverse Changes. (i) The information, reports, financial statements, exhibits and schedules furnished in writing by either of the Loan Parties to each of the Co-Agents or Lenders in connection with the negotiation, preparation or delivery of the Transaction Documents, including Quest Diagnostics’ Annual Report on Form 10-K for the year ended December 31, 20232024, but in each case excluding all projections, whether prior to or after the Eighth Amendment Effective Date, when taken as a whole, do not, as of the date such information was furnished, contain any untrue statement of material fact or omit to state a material fact necessary in order to make the statements herein or therein, in light of the circumstances under which they were made, not materially misleading; it being understood that certain financial information so furnished, including without limitation information contained in the Weekly Reports and Monthly Reports, has not been prepared in accordance with GAAP and might vary materially from information prepared and presented in accordance with GAAP on the same subject matter. 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, 2023 through and including the Eighth Amendment Effective Date2024, there has been no material adverse change in Quest Diagnostics’ consolidated financial condition, business or operations. Since December 31, 20232024, 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 collectability 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 Purchased Assets and Quality of Title. (i) Each Purchased Asset 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 Purchased Asset 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 Purchased Asset 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 Purchased Asset. (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 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 Purchased Assets 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 Private Receivables to pay all Collections thereon either (A) by wire transfer, ACH or other electronic funds transfer directly to a Collection Account in the name of the Borrower that at all times after December 31, 2016 is subject to a Collection Account Agreement, or (B) by mail addressed to a Lockbox that clears each Business Day through a Collection Account in the name of the Borrower that meets the requirements of the preceding clause (A). One of the Loan Parties or the applicable Originator has instructed all Obligors of Specified Government Receivables to pay all Collections thereon either (X) by wire transfer, ACH or other electronic funds transfer directly to a Collection Account in the name, and under the control, of the Originator whose services gave rise thereto which is swept each Business Day into a Collection Account in the name of the Borrower that meets the requirements of clause (A) above, or (Y) by mail addressed to a Lockbox that clears each Business Day through a Collection Account in the name, and under the control, of the Originator whose services gave rise thereto which is swept each Business Day into a Collection Account in the name of the Borrower that meets the requirements of clause (A) above. Each of the agreements establishing and governing the maintenance of the Lockboxes and Collection Accounts is in full force and effect, and at all times after December 31, 2016, each of the Collection Accounts in the name of the Borrower 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. (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, and each Participation Interest included as an Eligible Participation Interest in the Net Pool Balance in connection with any computation or recomputation of the Borrowing Base is an Eligible Participation Interest 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 collectability 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 Purchased Asset 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 Purchased Asset 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 (the “Bankruptcy Code”). (u) ▇▇▇▇▇▇▇ Rule; Investment Company Act; Other Restrictions. Such Loan Party (i) is not a “covered fund” under the ▇▇▇▇▇▇▇ Rule and (ii) is not required to register as, an “investment company” within the meaning of the Investment Company Act of 1940, as amended, or any successor statute. In determining that such Loan Party is not a covered fund, such Loan Party does not rely solely on the exemption from the definition of “investment company” set forth in Section 3(c)(1) and/or 3(c)(7) of the Investment Company Act of 1940. Such Loan Party is not 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. (w) Transaction Information. Such Loan Party and its Affiliates (or any third party with which such Loan Party or any Affiliate thereof has contracted) has not delivered, in writing or orally, to any Rating Agency, any Transaction Information without providing such Transaction Information to the applicable Co-Agent prior to delivery to such Rating Agency and has not participated in any oral

communications with respect to Transaction Information with any Rating Agency without the participation of such Co-Agent. (x) Risk Retention.

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. The Borrower will pay the Servicer the Servicer’s Fee pursuant hereto.

To the extent, if any, that the Borrower (or any other Affiliate thereof) shares items of expenses not reflected in the Servicer’s Fee, for legal, auditing and other professional services and directors’ fees, such expenses will be allocated to the extent practical on the basis of actual use or the value of services rendered, and otherwise on a basis reasonably related to the actual use or the value of services rendered, it being understood that Quest Diagnostics shall pay all expenses of the Borrower and, to the extent provided in this Agreement, the Agents relating to the preparation, negotiation, execution and delivery of the Transaction Documents, including, without limitation, legal, rating agency and other fees; (f) The Borrower’s operating expenses will not be paid by any other Loan Party or other Affiliate of the Borrower; (g) The Borrower will have its own stationery; (h) The books of account, financial reports and records of the Borrower will be maintained separately from those of Quest Diagnostics and each other Affiliate of the Borrower although they may appear in Quest Diagnostics’ consolidated general ledger; (i) Any financial statements of any Loan Party or Affiliate thereof which are consolidated to include the Borrower will contain detailed notes clearly stating that (A) all of the Borrower’s assets are owned by the Borrower, and (B) the Borrower is a separate legal entity with its own separate creditors that will be entitled to be satisfied out of the Borrower’s assets prior to any value in the Borrower becoming available to the Borrower’s equity holders; and the accounting records and any published financial statements of each of the Originators will clearly show that, for accounting purposes, the Purchased Assets and Related Assets have been sold by such Originator to the Borrower; (j) The Borrower’s assets will be maintained in a manner that facilitates their identification and segregation from those of the Servicer and the other Affiliates;

(k) Each Affiliate of the Borrower will strictly observe organizational formalities in its dealings with the Borrower, and, except as permitted pursuant to this Agreement with respect to Collections, funds or other assets of the Borrower will not be commingled with those of any of its Affiliates; (l) No Affiliate of the Borrower will maintain joint bank accounts with the Borrower or other depository accounts with the Borrower to which any such Affiliate (other than in the Borrower’s or such Affiliate’s existing or future capacity as the Servicer hereunder or under the Sale Agreement) has independent access, provided that prior to demand by any of the Agents pursuant to Section 7.1(i) to establish a segregated Collateral Account, Collections may be deposited into general accounts of Quest Diagnostics, subject to the obligations of the Servicer hereunder; (m) Each Affiliate of the Borrower will maintain arm’s length relationships with the Borrower, and each Affiliate of the Borrower that renders or otherwise furnishes services or merchandise to the Borrower will be compensated by the Borrower at market rates for such services or merchandise; (n) No Affiliate of the Borrower will be, nor will it hold itself out to be, responsible for the debts of the Borrower or the decisions or actions in respect of the daily business and affairs of the Borrower.

ARTICLE VIII. 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 all 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 all 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 all 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 and with OPTUM360, 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. Section 8.2 Duties of Servicer. (a) Appointment; Duties in General. Each of the Borrower, the Lenders, the LC Issuer and the Agents hereby appoints as its agent, the Servicer, as from time to time designated pursuant to Section 8.1, to enforce its rights and interests in and under the Collateral.

(b) Segregation of Collections. The Servicer shall not be required (unless otherwise requested by any of the Agents) to segregate the funds constituting Collections prior to the remittance

thereof in accordance with Article III.

(a) If the Administrative Agent notifies a Lender or any Person who has received funds on behalf of a Lender (any such Lender or Person, a “Payment Recipient”) that the Administrative Agent has determined in its sole discretion (whether or not after receipt of any notice under immediately succeeding clause (b)) that any funds received by such Payment Recipient from the Administrative Agent or any of its Affiliates were erroneously transmitted to, or otherwise erroneously or mistakenly received by, such Payment Recipient (whether or not known to such Lender or other Payment Recipient on its behalf) (any such funds, whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise, individually and collectively, an “Erroneous Payment”) and demands the return of such Erroneous Payment (or a portion thereof) in writing (provided that, without limiting any other rights or remedies (whether at law or in equity), the Administrative Agent may not make any such demand under this clause (a) with respect to an Erroneous Payment unless such demand is made within 30 days of the date of receipt of such Erroneous Payment by the applicable Payment Recipient), such Erroneous Payment shall at all times remain the property of the Administrative Agent and shall be segregated by the Payment Recipient and held in trust for the benefit of the Administrative Agent, and such Lender shall (or, with respect to any Payment Recipient who received such funds on its behalf, shall cause such Payment Recipient to) promptly, but in no event later than two (2) Business Days thereafter, return to the Administrative Agent the amount of any such Erroneous Payment (or portion thereof) as to which such a demand was made, in same day funds (in the currency so received), together with interest thereon in respect of each day from and including the date such Erroneous Payment (or portion thereof) was received by such Payment Recipient to the date such amount is repaid to the Administrative Agent in same day funds at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation from time to time in effect. A notice of the Administrative Agent to any Payment Recipient under this clause (a) shall be conclusive, absent manifest error. (b) Without limiting the immediately preceding clause (a), each Lender, or any Person who has received funds on behalf of a Lender, hereby further agrees that if it receives a payment, prepayment or repayment (whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise) from the Administrative Agent (or any of its Affiliates) (x) that

is in a different amount than, or on a different date from, that specified in a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, (y) that was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates), or (z) that such Lender, or other such recipient, otherwise becomes aware was transmitted, or received, in error or by mistake (in whole or in part) in each case: (i) (A) in the case of immediately preceding clauses (x) or (y), an error shall be presumed to have been made (absent written confirmation from the Administrative Agent to the contrary) or (B) an error has been made (in the case of immediately preceding clause (z)), in each case, with respect to such payment, prepayment or repayment; and (ii) such Lender shall (and shall cause any other recipient that receives funds on its respective behalf to) promptly (and, in all events, within one Business Day of its knowledge of such error) notify the Administrative Agent of its receipt of such payment, prepayment or repayment, the details thereof (in reasonable detail) and that it is so notifying the Administrative Agent pursuant to this Section 11.12(b). (c) Each Lender hereby authorizes the Administrative Agent to set-off, net and apply any and all amounts at any time owing to such Lender under any Transaction Document, or otherwise payable or distributable by the Administrative Agent to such Lender from any source, against any amount due to the Administrative Agent under Section 11.12(a) or under the indemnification provisions of this Agreement. (d) In the event that an Erroneous Payment (or portion thereof) is not recovered by the Administrative Agent for any reason, after demand therefor by the Administrative Agent in accordance with Section 11.12(a), from any Lender that has received such Erroneous Payment (or portion thereof) and/or from any Payment Recipient who received such Erroneous Payment (or portion thereof) on its respective behalf (such unrecovered amount, an “Erroneous Payment Return Deficiency”), upon the Administrative Agent’s notice to such Lender at any time, (i) such Lender shall be deemed to have assigned its Loans, as applicable (but not its corresponding Commitment) with respect to which such Erroneous Payment was made (the “Erroneous Payment Impacted Class”) in an amount equal to the Erroneous Payment Return Deficiency (or such lesser amount as the Administrative Agent may specify) (such assignment of Loans (but not Commitments) of the Erroneous Payment Impacted Class, the “Erroneous Payment Deficiency Assignment”) at par plus any accrued and unpaid interest (with the assignment fee to be waived by the Administrative Agent in such instance), and is hereby (together with the Borrower) deemed to execute and deliver assignment and assumption documentation with respect to such Erroneous Payment Deficiency Assignment, (ii) the Administrative Agent as the assignee Lender shall be deemed to acquire the Erroneous Payment Deficiency Assignment, (iii) upon such deemed acquisition, the Administrative Agent as the assignee Lender shall become a Lender hereunder with respect to such Erroneous Payment Deficiency Assignment and the assigning Lender shall cease to be a Lender hereunder with respect to such Erroneous Payment Deficiency Assignment, excluding, for the avoidance of doubt, its obligations under the indemnification provisions of this Agreement and its applicable Commitment(s) which shall survive as to such assigning Lender and (iv) the Administrative Agent may reflect in the Register its ownership interest in the Loans subject to the Erroneous Payment Deficiency Assignment. The Administrative Agent may, in its discretion, sell any Loans acquired pursuant to an Erroneous Payment Deficiency Assignment to an Eligible Assignee at par subject to the terms and conditions with respect to assignment of Loans set forth herein and upon

receipt of the proceeds of such sale, the Erroneous Payment Return Deficiency owing by the applicable Lender shall be reduced by the net proceeds of the sale of such Loan (or portion thereof), and the Administrative Agent shall retain all other rights, remedies and claims against such ▇▇▇▇▇▇ (and/or against any recipient that receives funds on its respective behalf). For the avoidance of doubt, no Erroneous Payment Deficiency Assignment will reduce the Commitment(s) of any Lender and such Commitment(s) shall remain available in accordance with the terms of this Agreement. (e) The parties hereto agree that an Erroneous Payment shall not pay, prepay, repay, discharge or otherwise satisfy any Obligations owed by the Borrower or any other Loan Party, except, in each case, to the extent such Erroneous Payment is, and solely with respect to the amount of such Erroneous Payment that is, comprised of funds received by the Administrative Agent from the Borrower or any other Loan Party for the purpose of reducing the Obligations. (f) To the extent permitted by applicable law, no Payment Recipient shall assert any right or claim to an Erroneous Payment, and hereby waives, and is deemed to waive, any claim, counterclaim, defense or right of set-off or recoupment with respect to any demand, claim or counterclaim by the Administrative Agent for the return of any Erroneous Payment received, including without limitation waiver of any defense based on “discharge for value” or any similar doctrine. (g) Each party’s obligations, agreements and waivers under this Section 11.12 shall survive the resignation or replacement of the Administrative Agent, any transfer of rights or obligations by, or the replacement of, a Lender, the termination of the Commitments and/or the repayment, satisfaction or discharge of all Obligations (or any portion thereof) under any Transaction Document. (h) Nothing referenced in this Section 11.12, including the payment of an Erroneous Payment and the rights and obligations of the parties related thereto under this Section 11.12, shall trigger the Loan Parties’ indemnification obligations hereunder including under Article XIII. ARTICLE XII. ASSIGNMENTS AND PARTICIPATIONS Section 12.1 Restrictions on Assignments, Etc.. (a) No Loan Party may assign its rights, or delegate its duties hereunder or any interest herein without the prior written consent of each of the Agents and satisfaction of the Rating Agency Condition; provided, however, that the foregoing shall not be deemed to restrict Quest Diagnostics’ right, prior to delivery of a Successor Notice, to request the Agents’ consent to the appointment of an Affiliate as replacement Servicer (subject to satisfaction of the Rating Agency Condition) or to delegate all or any portion of its duties as Servicer to other Originators, as sub-servicers, so long as Quest Diagnostics remains primarily liable for the performance or non-performance of such duties. (b) Each of the Conduits may, at any time, assign all or any portion of any of its Loans and interests in the Letters of Credit, or sell participations therein, to its Constituent Liquidity Banks (or to its Co-Agent for the ratable benefit of its Constituent Liquidity Banks). (c) In addition to, and not in limitation of, assignments and participations described in Section 12.1(b):

(i) In the event that PNC or any of the Liquidity Banks suffers a Downgrading Event, the applicable Co-Agent shall notify the Borrower thereof, and, within 5 Business Days after the Borrower’s receipt of such notice, the Borrower may advise such Co-Agent whether the Borrower intends to replace such Co-Agent’s Group (the “Affected Group”) with a new Group of one or more Eligible Assignees. If the Borrower notifies such Co-Agent that it wishes to effect a replacement, (1) the Lenders in the Affected Group shall promptly execute such assignments as may be reasonably necessary to transfer their rights and obligations to the members of the replacement Group against payment in full of the Affected Group’s Obligations, or (2) if an assignment is not practicable, the parties hereto shall promptly enter into such joinders and amendments to this Agreement as may be reasonably necessary to effect the replacement of the Affected Group with the new Group of one or more Eligible Assignees; (ii) Each of the Lenders may assign all or any portion of its Loans and, if applicable, its Commitment and Liquidity Commitment, to any Eligible Assignee with the prior written consent of (A) the Borrower and (B) such Lender’s applicable Co-Agent, which consents shall not be unreasonably withheld or delayed; (iii) Notwithstanding any other provision of this Agreement to the contrary, each of the Lenders may at any time pledge or grant a security interest in all or any portion of its rights (including, without limitation, rights to payment of Principal and Interest) under this Agreement to secure obligations of such Person to a Federal Reserve Bank located in the United States of America, without notice to or consent of any other party hereto; provided that no such pledge or grant of a security interest shall release such Lender from any of its obligations hereunder or substitute any such pledgee or grantee for such Lender as a party hereto; and (iv) Each of the Lenders may, without the prior written consent of the Borrower or any of the Agents, sell participations in all or any portion of their respective rights and obligations in, to and under the Transaction Documents and the Obligations in accordance with Sections 12.2 and 14.7. (d) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain 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 Commitments of, and principal amounts (and stated interest) of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive (absent manifest error), and the Borrower, the Administrative Agent 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, at any reasonable time and from time to time upon reasonable prior notice. In addition, the Register shall be available for inspection by any Lender as to entries pertaining to it at any reasonable time and from time to time upon reasonable prior notice. Each Lender that sells a participation pursuant to this Agreement shall, acting as a non-fiduciary agent of the Borrower solely for the purpose of maintaining a register in order to satisfy the requirements of Section 5f.103-1(c) of the United States Treasury Regulations, maintain a register on which it records the name and address of each participant to which it has sold a participation and the principal amounts (and stated interest) of each such participant’s interest in the Loans or other rights and obligations of such Lender under this Agreement (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any participant or any information relating to a participant’s interest in any Commitments, Liquidity

Commitments, Loans, Letters of Credit or its other obligations under any Transaction Document) except to the extent that such disclosure is necessary to establish that such Commitment, Liquidity Commitment, Loan, Letter of Credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error. Section 12.2 Rights of Assignees and Participants. (a) Upon the assignment by a Lender in accordance with Section 12.1(b) or (c), the Eligible Assignee(s) receiving such assignment shall have all of the rights and obligations of such Lender with respect to the Transaction Documents and the Obligations (or such portion thereof as has been assigned). (b) In no event will the sale of any participation interest in any Lender’s or any Eligible Assignee’s rights under the Transaction Documents or in the Obligations relieve the seller of such participation interest of its obligations, if any, hereunder or, if applicable, under the Liquidity Agreement to which it is a party. Section 12.3 Terms and Evidence of Assignment. Any assignment to any Eligible Assignee(s) pursuant to Section 1.2(c), 12.1(b) or 12.1(c) shall be upon such terms and conditions as the assigning Lender and the applicable Co-Agent, on the one hand, and the Eligible Assignee, on the other, may mutually agree, and shall be evidenced by such instrument(s) or document(s) as may be satisfactory to such Lender, the applicable Co-Agent and the Eligible Assignee(s). Any assignment made in accordance with the terms of this Article XII shall relieve the assigning Lender of its obligations, if any, under this Agreement (and, if applicable, the Liquidity Agreement to which it is a party) to the extent assigned and no Lender may assign or otherwise transfer any of its rights and obligations hereunder except in accordance with the terms of this Article XII. ARTICLE XIII. INDEMNIFICATION Section 13.1 Indemnities by the Borrower. (a) General Indemnity. Without limiting any other rights which any such Person may have hereunder or under applicable law, the Borrower hereby agrees to indemnify each of the Affected Parties, each of their respective Affiliates, and all successors, transferees, participants and assigns and all officers, directors, shareholders, controlling persons, employees and agents of any of the foregoing (each, an “Indemnified Party”), forthwith on demand, from and against any and all damages, losses, claims, liabilities and reasonable related out-of-pocket costs and expenses, including reasonable attorneys’ fees and disbursements (all of the foregoing being collectively referred to as “Indemnified Amounts”) awarded against or incurred by any of them arising out of or relating to the Transaction Documents or the transactions contemplated thereby (including the issuance or Modification of, the fronting for, or any drawing under, any Letter of Credit), the LC Collateral Account, the Obligations or the Collateral, excluding, however: (i) Indemnified Amounts to the extent determined by a court of competent jurisdiction to have resulted from bad faith, gross negligence or willful misconduct on the part of such Indemnified Party, and (ii) recourse (except as otherwise specifically provided in this Agreement) 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 or the related Obligor’s refusal to pay; provided, however, that prior to the occurrence of an Event of Default, the Indemnified Parties shall only be entitled to seek indemnity for the reasonable fees and disbursements of a single law firm as special counsel to all such Indemnified Parties (and, if required, a single law firm as local counsel to all such Indemnified Parties in each relevant jurisdiction where the law firm acting as special counsel is not licensed to practice). Without limiting the foregoing, the Borrower shall indemnify each Indemnified Party for Indemnified Amounts arising out of or relating to: (A) the creation of any Lien on, or transfer by any Loan Party of any interest in, the Collateral other than as provided in the Transaction Documents; (B) any representation or warranty made by any Originator or Loan Party (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 any Originator or Loan Party pursuant thereto, which shall have been false, incorrect or misleading in any respect when made or deemed made or delivered, as the case may be; (C) the failure by any Loan Party to comply with any applicable law, rule or regulation with respect to any Receivable or the related Contract and/or Invoice, including, without limitation, any state or local assignment of claims act or similar legislation prohibiting or imposing notice and acknowledgement requirements or other limitations or conditions on the sale of participations in a Specified Government Receivable, or the nonconformity of any Receivable or the related Contract and/or Invoice with any such applicable law, rule or regulation; (D) the failure to vest and maintain vested in the Borrower a perfected ownership interest in all Collateral; or the failure to vest and maintain vested in the Administrative Agent, for the benefit of the Secured Parties, a valid and perfected first priority security interest in the Collateral, free and clear of any other Lien, other than a Lien arising solely as a result of an act of one of the Secured Parties, now or at any time thereafter; (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;

(G) any matter described in Section 3.4; (H) any failure of any Loan Party, as the Borrower, the Servicer or otherwise, to perform its duties or obligations in accordance with the provisions of this Agreement or the other Transaction Documents to which it is a party; (I) any claim of breach by any Loan Party of any related Contract and/or Invoice with respect to any Receivable; (J) any Other Taxes (and all interest and penalties thereon or with respect thereto, and all out-of-pocket costs and expenses, including the reasonable fees and expenses of counsel in defending against the same), which may arise by reason of the Administrative Agent’s security interest in the Collateral; (K) the commingling of Collections of Receivables at any time with other funds; (L) any investigation, litigation or proceeding related to or arising from this Agreement or any other Transaction Document, the transactions contemplated hereby or thereby, the use of the proceeds of any Loan, the issuance of any Letter of Credit, the security interest in the Purchased Assets and Related Assets or any other investigation, litigation or proceeding relating to the Borrower or any of the Originators in which any Indemnified Party becomes involved as a result of any of the transactions contemplated hereby or thereby (other than an investigation, litigation or proceeding (1) relating to a dispute solely amongst the Lenders (or certain Lenders) and the Administrative Agent or (2) excluded by Section 13.1(a)); (M) any products or professional liability, personal injury or damage suit, or other similar claim arising out of or in connection with merchandise, insurance or services that are the subject of any Contract, Invoice or any Purchased Asset; (N) any inability to litigate any claim against any Obligor in respect of any Receivable as a result of such Obligor being immune from civil and commercial law and suit on the grounds of sovereignty or otherwise from any legal action, suit or proceeding; (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 Private Receivables owing from any single Obligor and its Affiliated Obligors which causes the aggregate Unpaid Net Balance of all such Private Receivables to exceed the applicable Obligor Concentration Limit; or (Q) any amount that the Administrative Agent is required to pay to any Collection Bank pursuant to the terms of a Collection Account Agreement because of the Borrower’s failure to make such payment.

(b) Contest of Tax Claim; After-Tax Basis. If any Indemnified Party shall have notice of any attempt to impose or collect any Tax or governmental fee or charge for which indemnification will be sought from any Loan Party under Section 13.1(a)(J), such Indemnified Party shall give prompt and timely notice of such attempt to the Borrower and the Borrower shall have the right, at its expense, to participate in any proceedings resisting or objecting to the imposition or collection of any such Tax, governmental fee or charge. Indemnification hereunder shall be in an amount necessary to make the Indemnified Party whole after taking into account any tax consequences when actually realized by the Indemnified Party of the payment of any of the aforesaid taxes or payments of amounts indemnified against hereunder (including any deduction) and the receipt of the indemnity payment provided hereunder or of any refund of any such tax previously indemnified hereunder, including the effect of such tax, amount indemnified against, deduction or refund on the amount of tax measured by net income or profits which is or was payable by the Indemnified Party. 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 13.3 FATCA. If a payment made to any Agent or any Lender hereunder would be subject to U.S. federal withholding Tax imposed by FATCA if such payee were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Internal Revenue Code, as applicable), such payee shall deliver to the Borrower at the time or times prescribed by law and at such time or times reasonably requested by the Borrower, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and such additional documentation reasonably requested by the Borrower as may be necessary for the Borrower to comply with its obligations under FATCA and to determine that such payee has complied with such payee’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 13.3, the term “FATCA” shall include any amendments made to FATCA after the date of this Agreement. ARTICLE XIV. MISCELLANEOUS Section 14.1 Amendments, Etc. Except as otherwise expressly provided in this Agreement (including, without limitation, Section 4.6), no amendment or waiver of any provision of this Agreement nor consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be in writing and signed by each of the Loan Parties and the Co-Agents, and any such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that: (a) Before any of the Co-Agents enters into such an amendment or grants such a waiver or consent that is deemed to be material by S&P, ▇▇▇▇▇’▇ or, at any time while it is rating any Conduit’s Commercial Paper Notes, Fitch, the Rating Agency Condition (if applicable to such Co-Agent’s Conduit) must be satisfied with respect to each of such Conduits, (b) Without the prior written consent of all Liquidity Banks in a Co-Agent’s Group, such Co-Agent will not amend, modify or waive any provision of this Agreement which (i) would reduce or subordinate, or would have the effect of reducing or subordinating, the amount of any Principal or Interest that is payable on account of its Conduit’s Loans or would delay any scheduled date for payment thereof; (ii) would or would have the effect of subordinating all or the Administrative Agent’s Lien on all or any substantial portion of the Collateral; (iii) would decrease or would have the effect of decreasing the Required Reserve or the spread included in any Interest Rate, or would change the amount of the Servicer’s Fee; (iv) would modify or have the effect of modifying any provision of this Agreement that provides for the Groups or certain of each Group’s members to participate in any Advance or payment on a ratable basis; (v) would modify or circumvent or would have the effect of modifying or circumventing any provision of this Section 14.1; (vi) would modify or have the effect of modifying any yield protection or indemnity provision which expressly inures to the benefit of assignees or participants of such Co-Agent’s Conduit; or (vi) would increase any such Liquidity Bank’s Commitment, (c) Without the prior written consent of each Agent affected thereby, no such amendment, waiver or consent shall amend, modify, terminate or waive any provision of Article XI as the same

applies to any Agent, or any other provision hereof as the same applies to the rights or obligations of any Agent, in each case without the consent of such Agent, (d) If less than all of the Co-Agents decline to approve a requested amendment and within 90 days after the Borrower’s request for approval of such amendment, and either (i) the Borrower prepays the Obligations of the dissenting Co-Agent’s (or Co-Agents’) Group in full or (ii) finds one or more Eligible Assignees to replace each such Co-Agent’s Group, then the requested amendment shall become effective on the effective date of such prepayment or assignment as to the remaining Lenders (and, if applicable, as to any replacement Lenders), and (e) If less than all of the Co-Agents decline to approve a requested waiver and (i) the Borrower either (A) identifies one or more Eligible Assignee(s) to accept immediate written assignments of such Co-Agent’s Group’s Commitment(s) and outstanding Obligations, or (B) immediately pays all Obligations owing to the members of such Co-Agent’s (or Co-Agents’) Group(s) in full, and (ii) the Administrative Agent has not already declared the Termination Date to have occurred, such waiver shall become effective as to the remaining Lenders on the effective date of such assignment or repayment.

Section 14.14 Business Associate Agreement; Health Care Data Privacy and Security Requirements. (a) Definitions. “HIPAA” means the Health Insurance Portability and Accountability Act of 1996. The terms “▇▇▇ ▇▇▇▇,” “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 sub-contractors 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 sub-contractors 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 any 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 other senior Indebtedness and its Liquidity Banks. Section 14.17 PATRIOT Act. Each Lender that is subject to the requirements of the Act hereby notifies the Loan Parties that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies the Loan Parties, the Originators and their respective Subsidiaries, which information includes the name and address of the Loan Parties, the Originators and their respective Subsidiaries and other information that will allow such Lenders to identify such parties in accordance with the Act. Section 14.18 Defaulting Lenders. (a) If any Committed Lender becomes a Defaulting Lender at any time when there are undrawn Letters of Credit outstanding, then all or any part of such Defaulting Lender’s participation in such Letters of Credit shall be reallocated among the Committed Lenders that are not Defaulting Lenders in accordance with their respective Ratable Shares (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that (i) the conditions precedent to Credit Events are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (ii) such reallocation does not cause the Credit Exposure of any Lender to exceed such Lender’s applicable Commitment. Subject to Section 1.9, no such reallocation shall constitute a waiver or release of any claim of any party against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of any other Lender as a result of such other ▇▇▇▇▇▇’s increased Credit Exposure following such reallocation.

(b) If any Committed Lender becomes a Defaulting Lender at any time when there are Advances outstanding, then all or any part of such Defaulting Lender’s Loans shall be reallocated among the Committed Lenders that are not Defaulting Lenders in accordance with their respective Ratable Shares (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that (i) the conditions precedent to Credit Events are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (ii) such reallocation does not cause the Credit Exposure of any Lender to exceed such ▇▇▇▇▇▇’s Commitment. No such reallocation shall constitute a waiver or release of any claim of any party against a Defaulting Lender arising from that ▇▇▇▇▇▇ having become a Defaulting Lender, including any claim of any other Lender as a result of such other ▇▇▇▇▇▇’s increased Credit Exposure following such reallocation. (c) If any Committed Lender becomes a Defaulting Lender at any time when there are undrawn Letters of Credit or Advances outstanding and the reallocation described in the paragraph above cannot, or can only partially, be effected, then the Borrower shall (i) within two (2) Business Days following notice by the LC Issuer or the Administrative Agent, (A) cash collateralize for the benefit of the LC Issuer a portion of the amount of the then outstanding Letters of Credit equal to such Defaulting Lender’s Ratable Share (determined after giving effect to any reallocation of its participation in Letters of Credit pursuant to clause (a) above) of such undrawn stated amount of outstanding Letters of Credit by depositing such amount into the LC Collateral Account, and/or (B) reduce the outstanding Principal balance of the Loans of the other Lenders in an aggregate amount, and (ii) maintain funds in the LC Collateral Account to cash collateralize such Defaulting Lender’s Ratable Share (determined after giving effect to any reallocation of its participation in Letters of Credit pursuant to clause (a) above) of undrawn stated amount of outstanding Letters of Credit. The Administrative Agent shall apply funds deposited into the LC Collateral Account to satisfy a Defaulting Lender’s obligation to fund its portion of a Reimbursement Advance requested or deemed requested by the Borrower and to fund any LC Advance required to be made by such Defaulting Lender. (d) The Borrower shall not be required to pay such Defaulting Lender any fees payable with respect to the amount of the undrawn Letters of Credit that is so Cash Collateralized by the Borrower. (e) No amount payable by the Borrower for the account of a Defaulting Lender (whether on account of Principal, Interest, indemnity payments or other amounts) shall be paid or distributed to such Defaulting Lender (or its Co-Agent), but instead shall be deposited to the LC Collateral Account until the amount therein is equal to the amount of such Defaulting Lender’s Pro Rata Share of the stated amount of the undrawn Letters of Credit that is not cash collateralized, and to the extent of any remaining amounts, to pay to such Defaulting Lender amounts owed to it. (f) No Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent under this Agreement (and any amendment, waiver or consent which by its terms requires the consent of all Lenders or each affected Lender may be effected with the consent of the applicable Lenders other than Defaulting Lenders), except that (x) the Commitment of any Defaulting Lender may not be increased or extended without the consent of such Lender and (y) any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender that by its terms affects any Defaulting Lender more adversely than other affected Lenders shall require the consent of such Defaulting Lender.

THE CREDIT Section 1.1 The Facility.¶ 1.1.1. Advances. 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 prior to the Commitment Expiry Date request Advances by delivering a Borrowing Request to the Co-Agents in accordance with Section 2.1. Upon receipt of a copy of each Borrowing Request from the Borrower or Servicer, 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) PNC severally agrees to make a Loan to the Borrower in an amount equal to its Group’s Commitment Percentage of the requested Advance on the terms and subject to the conditions hereof, provided that at no time may the aggregate Principal amount of PNC’s Credit Exposure at any one time outstanding exceed the amount of PNC’s Commitment, and (ii) the PNC Group’s Commitment Percentage of the Borrowing Base (such lesser amount, the “PNC Allocation Limit”); (b) in the event that Gotham elects not to make a Loan to the Borrower in an amount equal to its Group’s Commitment Percentage of the requested Advance, the Gotham Agent shall promptly notify the Borrower and, unless the Borrower cancels its Borrowing Request, each of the Liquidity Banks in the Gotham Group severally agrees to make its Pro Rata 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’ Credit Exposure at any one time outstanding exceed the lesser of (i) the 2

aggregate amount of the Gotham Liquidity Banks’ Commitments, and (ii) the Gotham Group’s Commitment Percentage of the Borrowing Base (such lesser amount, the “Gotham Allocation Limit”); and (c) in the event that Atlantic elects not to make a Loan to the Borrower in an amount equal to its Group’s Commitment Percentage of the requested Advance, the Atlantic Agent shall promptly notify the Borrower and, unless the Borrower cancels its Borrowing Request, each of the Liquidity Banks in the Atlantic Group severally agrees to make its Pro Rata 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 Atlantic’s and its Liquidity Banks’ Credit Exposure at any one time outstanding exceed the lesser of (i) the aggregate amount of the Atlantic Liquidity Banks’ Commitments, and (ii) the Atlantic Group’s Commitment Percentage of the Borrowing Base (such lesser amount, the “Atlantic Allocation Limit”); Each Loan (other than an LC Loan) shall be in the minimum amount of $1,000,000 or a larger integral multiple of $500,000. 1.1.2. Letters of Credit. 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 prior to the Commitment Expiry Date request that the LC Issuer issue Letters of Credit for the account of the Borrower, and from time to time upon receipt of a duly executed and completed LC Application, the LC Issuer hereby agrees to issue Letters of Credit and to renew, extend, increase, decrease or otherwise modify each Letter of Credit (“Modify,” and each such action a “Modification”); provided that no Letter of Credit shall be issued or Modified by the LC Issuer if, after giving effect thereto, (a) the LC Obligations would exceed the LC Sublimit, or (b) the Aggregate Credit Exposure would exceed the lesser of (i) the Aggregate Commitment and (ii) the Borrowing Base; and provided, further, that each Letter of Credit issued pursuant to this Section 1.1.2 shall have a face amount of not less than $5,000. On any date of determination, the LC Obligations, whether still contingent or due and payable but unpaid, will constitute usage of the LC Sublimit and, accordingly, the Aggregate Commitment. 1.1.3. Aggregate Credit Exposure; Termination of Commitments; Uncommitted Accordion; Collateral. (a) In no event may the Aggregate Credit Exposure hereunder exceed the lesser of (i) the Aggregate Commitment, or (ii) the Borrowing Base. (b) Each Commitment shall terminate on the earlier to occur of (i) the Commitment Expiry Date and (ii) the Termination Date. (c) Not more than twice during the period from and after November 20, 2025 and prior to the earlier to occur of the Commitment Expiry Date and the Termination Date, provided that no Event of Default or Unmatured Default exists and is continuing, the Borrower (or the Servicer, on the Borrower’s behalf) may request an increase in the Aggregate Commitment in an aggregate amount during such period not to exceed $200,000,000 across all Groups by delivering not less than three (3) weeks’ prior written notice to the Co-Agents specifying (i) the aggregate amount of the requested increase (the “Aggregate Requested Increase”), (ii) each Group’s Commitment Percentage of the Aggregate Requested Increase (each, a “Group’s Requested Increase”), and (iii) each Committed Lender’s Pro Rata Share of its Group’s Requested Increase (each, a “Committed Lender’s 3

Increase Amount”). Upon receipt of a written request complying with the preceding sentence, each of the Co-Agents will promptly deliver a copy of such request to the Committed Lender(s) in its Group, and each such Committed Lender will promptly seek credit approval to increase its Commitment in an amount equal to such Committed Lender’s Increase Amount; provided, however, that nothing herein shall be deemed to constitute a commitment by any Lender to provide, or to obtain credit approval to provide, all or any portion of the Aggregate Requested Increase. If any Co-Agent notifies the Loan Parties and the Administrative Agent that any Committed Lender in its Group has obtained credit approval to increase its Commitment by an amount equal to such Committed Lender’s Increase Amount, such Committed Lender’s Commitment and the Aggregate Commitment will automatically increase by such Committed Lender’s Increase Amount on the Business Day at least five (5) Business Days but in any event no more than three (3) weeks after delivery of the request for such increase (unless otherwise approved by the Co-Agents) and at least 30 days prior to the Scheduled Termination Date. In no event will any increase in the Aggregate Commitment pursuant to this Section 1.1.3(c) result in any change to the LC Sublimit. If any Committed Lender declines to agree to increase its Commitment by its Committed Lender’s Increase Amount: (i) the Borrower may ask the Committed Lenders in the other Groups if they would like to increase their respective Committed Lender’s Increase Amounts by all or any portion of the declined amount; or (ii) the Borrower, upon notice to and consent of the Administrative Agent and the LC Issuer (which consent shall not be unreasonably withheld or delayed), may add a new Group that consists of at least one new Committed Lender willing to provide the declining Committed Lender’s Group Requested Increase, and/or replace the declining Committed Lender’s Group in its entirety with a new Group that consists of at least one new Committed Lender willing to provide a replacement Commitment equal to the sum of the replaced Group’s existing Commitment plus its Group Requested Amount. Any change in the Commitments or Groups pursuant to clause (i) or (ii) above will become effective on the first day of the calendar month following confirmation by the Administrative Agent that all documentation necessary to evidence such changes has been executed and delivered. (d) Each of the Loans, the LC Obligations 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) Each Advance hereunder shall consist of Loans made by (i) Gotham and/or its Liquidity Bank(s), (ii) Atlantic and/or its Liquidity Bank(s), and (iii) PNC, and (except for any Advance which does not increase Aggregate Principal) 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. (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 (i) in the case of the proceeds of an LC Loan, to the account specified 4

by the LC Issuer, and (ii) in the case of the proceeds of a Loan, to the account specified by the Borrower in its Borrowing Request, in each of the foregoing cases, 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 any Conduit 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 Term SOFR 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¶. (a) Prior to the occurrence of an Event of Default and during the continuance thereof, each Loan shall bear interest at the applicable Interest Rate, payable in arrears on each Settlement Date. Notwithstanding the foregoing, 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; provided that no Interest at the Default Rate shall accrue or be payable to a Defaulting Lender so long as such Lender shall be a Defaulting Lender. (b) Each Term SOFR 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 rate per annum equal to the applicable Adjusted Term SOFR rate for such Interest Period. (c) 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. (d) Each Alternate Base Rate Loan and each Daily Term SOFR Loan, respectively, 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 rate per annum equal to the Alternate Base Rate or the applicable Daily Term SOFR rate, respectively, for such day. Changes in the rate of Interest on Alternate 5

Base Rate Loans and Daily Term SOFR Loans will take effect simultaneously with each change in the Alternate Base Rate or the applicable Daily Term SOFR rate, respectively. (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 Repayment of the Advances.¶ (a) [Reserved]. (b) Unless the Termination Date has earlier occurred, on the Commitment Expiry Date, the Advances and LC Advances shall become due and will be payable on Settlement Dates to the extent of Collections received on the Commitment Expiry Date and each Business Day thereafter until paid in full, together with all accrued and unpaid Interest thereon. In addition to the foregoing, unless the Termination Date has earlier occurred, on the Commitment Expiry Date and on each Settlement Date thereafter, the LC Obligations shall be required to be Cash Collateralized to the extent of Collections received on the Commitment Expiry Date and each Business Day thereafter until paid or Cash Collateralized in full, together with all Expected LC Fees. (c) All payments and Cash Collateral Payments required under Section 1.4(b) shall be made on Settlement Dates occurring on or after the Commitment Expiry Date in the order of priority specified in Section 3.2(d). (d) The Borrower promises to pay the LC Obligations, together with all LC Fees, LC Processing Fees, LC Fronting Fees and, if applicable, Interest thereon, in accordance with the terms of the Fee Letter and Sections 2.8 and 2.10 of this Agreement. Section 1.5 Voluntary and Mandatory Prepayments¶. Subject, in the case of CP Rate Loans and Term SOFR 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, (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, and (iii) given at least one (1) U.S. Government Securities Business Day prior to the proposed prepayment date, in the case of any Term SOFR Loan or Daily Term SOFR Loan (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 among 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. 6

(b) If, on any Business Day, the aggregate outstanding Principal amount of the Credit Exposure of the PNC Group exceeds the PNC Group Allocation Limit, not later than 12:00 noon (New York City time) on the first Business Day thereafter, (i) the Borrower shall prepay the PNC Group’s Loans by wire transfer to the PNC Group Agent in an aggregate amount sufficient to eliminate such excess, together with accrued and unpaid Interest on the amount of Loans prepaid, and (ii) if there are insufficient Loans be so prepaid, the Borrower will Cash-Collateralize the LC Obligations by wire transfer to the LC Collateral Account in an aggregate amount sufficient to eliminate the remainder of such excess. (c) (i) If, on any Business Day, the aggregate outstanding Principal amount of the Credit Exposure of the Gotham Group exceeds the Gotham Allocation Limit, not later than 12:00 noon (New York City time) on the first Business Day thereafter, (i) the Borrower shall prepay the Gotham Group’s Loans by wire transfer to the Gotham Group Agent in an aggregate amount sufficient to eliminate such excess, together with accrued and unpaid Interest on the amount of Loans prepaid, and (ii) if there are insufficient Loans be so prepaid, the Borrower will Cash-Collateralize the LC Obligations by wire transfer to the LC Collateral Account in an aggregate amount sufficient to eliminate the remainder of such excess. (ii) If, on any Business Day, the aggregate outstanding Principal amount of the Credit Exposure of the Atlantic Group exceeds the Atlantic Allocation Limit, not later than 12:00 noon (New York City time) on the first Business Day thereafter, (i) the Borrower shall prepay the Atlantic Group’s Loans by wire transfer to the Atlantic Group Agent in an aggregate amount sufficient to eliminate such excess, together with accrued and unpaid Interest on the amount of Loans prepaid, and (ii) if there are insufficient Loans be so prepaid, the Borrower will Cash-Collateralize the LC Obligations by wire transfer to the LC Collateral Account in an aggregate amount sufficient to eliminate the remainder of such excess. (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 Constituents their respective shares (if any) thereof not later than 1:00 p.m. (New York City time) on the date when received. Any prepayment or Loans made pursuant to Section 1.5(b) or (c) shall be applied first, to the ratable reduction of the applicable Group’s Alternate Base Rate Loans outstanding, second, to the ratable reduction of the applicable Group’s Term SOFR Loans and Daily Term SOFR Loans outstanding, and lastly, to the reduction of the applicable Group’s CP Rate Loans selected by the Borrower (or the Servicer, on the Borrower’s behalf). (e) If, on any Business Day, the aggregate of the LC Obligations exceeds the LC Sublimit or any LC Processing Fees are due and owing pursuant to Section 2.10 and are not paid when due (payable on the Settlement Date as invoiced by the LC Issuer pursuant to Section 3.1(c)), not later than 12:00 noon (New York City time) on the first Business Day thereafter, the Borrower shall Cash-Collateralize the LC Obligations in the amount of such excess and/or LC Processing Fees, as the case may be, by wire transfer to the LC Collateral Account. (f) 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 Commitments¶. Subject to the limitations set forth below, the Borrower may permanently reduce the aggregate Commitments, in whole, or ratably among 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 of the aggregate Commitments 7

and the Committed Lenders’ respective Ratable Shares thereof. Notwithstanding the foregoing, no Commitment may be reduced below the aggregate outstanding Credit Exposure thereunder unless accompanied by a simultaneous prepayment of Principal or pledge and deposit of cash collateral into the LC Collateral Account in an aggregate amount equal to such excess Credit Exposure. In addition to and without limiting any other requirements for termination, prepayment and/or the funding of the LC Collateral Account hereunder, no termination of the Administrative Agent’s security interest in the Collateral shall be effective unless and until (x) the amount on deposit in the LC Collateral Account is at least equal to the then Outstanding Face Amount plus the Expected LC Fees, (y) the Aggregate Principal is reduced to zero and (z) all accrued and unpaid fees and all other amounts owed to the Agents, the LC Issuer or the Lenders under this Agreement and each of the other Transaction Documents have been paid or Cash Collateralized in full. Each Commitment Reduction Notice shall be irrevocable once delivered to the Co-Agents and, as applicable, the LC Issuer. Section 1.7 Distribution of Certain Notices; Notification of Interest Rates¶. Promptly after receipt thereof, (a) the LC Issuer will notify the each of the Co-Agents of the contents of each LC Application, and the PNC Group Agent will notify the PNC Group, the Atlantic Agent will notify the Atlantic Group and the Gotham Agent will notify the Gotham Group, of the contents of each Monthly Report, Borrowing Request, Draw Notice, LC Application, LC Advance Notice, 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 Constituents and the Borrower of each determination of and change in Interest Rates. Section 1.8 Absence of Notes.¶ The LC Issuer and each Lender shall maintain in accordance with its usual practice and Section 5f.103-1(c) of the United States Treasury Regulations an account or accounts evidencing the indebtedness of the Borrower to such Person resulting from each Letter of Credit issued by the LC Issuer, or, as applicable, each Loan made by such Lender from time to time, including the amounts of Principal and Interest payable and paid to such Person from time to time hereunder. Upon request of the Borrower, the LC Issuer or, as applicable, each Lender’s Co-Agent or the Administrative Agent, will confirm the outstanding Principal balances of its Credit Extensions and the amount of any accrued and unpaid Interest thereon. The entries maintained in the accounts maintained pursuant to this Section shall be prima facie evidence of the existence and amounts of the Obligations therein recorded; provided, however, that the failure of the LC Issuer or 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 1.9 Acknowledgement and Consent to Bail-In of EEA Financial Institutions¶. Notwithstanding anything to the contrary in any Transaction Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any liability of any EEA Financial Institution arising under any Transaction Document, to the extent such liability is unsecured, may be subject to the write-down and conversion powers of an EEA Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by: (a) the application of any Write-Down and Conversion Powers by an EEA Resolution Authority to any such liabilities arising hereunder which may be payable to it by any party hereto that is an EEA Financial Institution; and (b) the effects of any Bail-in Action on any such liability, including, if applicable: (i) a reduction in full or in part or cancellation of any such liability; (ii) a conversion of all, or a portion of, such liability 8

into shares or other instruments of ownership in such EEA Financial Institution, its parent undertaking, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Transaction Document; or (iii) the variation of the terms of such liability in connection with the exercise of the write-down and conversion powers of any EEA Resolution Authority. Section 1.10 Rates.¶ The Administrative Agent does not warrant or accept responsibility for, and shall not have any liability with respect to (a) the continuation of, administration of, submission of, calculation of or any other matter related to the Alternate Base Rate, the Term SOFR Reference Rate, Term SOFR, Daily One Month Term SOFR or Daily Three Month Term SOFR, or any component definition thereof or rates referred to in the definition thereof, or any alternative, successor or replacement rate thereto (including any Benchmark Replacement), including whether the composition or characteristics of any such alternative, successor or replacement rate (including any Benchmark Replacement) will be similar to, or produce the same value or economic equivalence of, or have the same volume or liquidity as, the Alternate Base Rate, the Term SOFR Reference Rate, Term SOFR, Daily One Month Term SOFR, Daily Three Month Term SOFR or any other Benchmark prior to its discontinuance or unavailability, or (b) the effect, implementation or composition of any Conforming Changes. The Administrative Agent and its affiliates or other related entities may engage in transactions that affect the calculation of the Alternate Base Rate, the Term SOFR Reference Rate, Term SOFR, Daily One Month Term SOFR, Daily Three Month Term SOFR, any alternative, successor or replacement rate (including any Benchmark Replacement) or any relevant adjustments thereto, in each case, in a manner adverse to the Borrower. The Administrative Agent may select information sources or services in its reasonable discretion to ascertain the Alternate Base Rate, the Term SOFR Reference Rate, Term SOFR, Daily One Month Term SOFR, Daily Three Month Term SOFR or any other Benchmark, in each case pursuant to the terms of this Agreement, and shall have no liability to the Borrower, any Lender or any other person or entity for damages of any kind, including direct or indirect, special, punitive, incidental or consequential damages, costs, losses or expenses (whether in tort, contract or otherwise and whether at law or in equity), for any error or calculation of any such rate (or component thereof) provided by any such information source or service. ARTICLE II. BORROWING, LETTER OF CREDIT 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 2:00 p.m. (New York City time) at least one (1) Business Day before the Borrowing Date of each Advance that will bear interest at a CP Rate, and not later than 2:00 p.m. (New York City Time) at least one (1) U.S. Government Securities Business Day before the Borrowing Date of each Advance that will bear interest at an Adjusted Term SOFR rate or a Daily Term SOFR rate. On each Borrowing Date, each applicable Lender shall make available its Loan 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 Constituents 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 9

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, whether they are Loans or LC 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 applicable Commitment Expiry Date. 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 (A) may request Interest Periods from time to time to apply to the Term SOFR Loans; provided, however, that (x) at any time while any Lender has Term SOFR Loans outstanding, at least one Interest Period of such Lender shall mature on each Settlement Date and (y) no Interest Period of any Lender’s Loan which began prior to the applicable Commitment Expiry Date shall extend beyond such Commitment Expiry Date; and (B) shall specify whether Daily Term SOFR Loans will bear interest based on Adjusted Daily One Month Term SOFR or Adjusted Daily Three Month Term SOFR. (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 Term SOFR Loans except during the continuance of an Event of Default, each of the Co-Agents shall have the right to subdivide any requested Term SOFR Loan into one or more Term SOFR 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 Term SOFR Loan unless it shall have given each of the applicable Co-Agent(s) written notice of its desire therefor not later than 2:00 p.m. (New York City time) at least one (1) U.S. Government Securities Business Day 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 2:00 p.m. (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 10

case, in the precise amount necessary to refinance the maturing CP Rate Loan and the accrued and unpaid Interest thereon. (e) Unless the Co-Agents shall have received written notice by 2:00 p.m. (New York City time) on the first (1st) Business Day prior to the last day of an Interest Period that the Borrower intends to reduce the aggregate Principal amount of the Term SOFR Loans outstanding from the Liquidity Banks, each of the Liquidity Banks shall be entitled to assume that the Borrower desires to refinance its maturing Term SOFR Loans on the last day of such Interest Period with Alternate Base Rate Loans. Section 2.3 Computation of Concentration Limits and Unpaid Net Balance¶. The Obligor Concentration Limits and the aggregate Unpaid Net Balance of Private Receivables (as defined in the Sale Agreement) of each Obligor and its Affiliated Obligors (if any) shall be calculated as if each such Obligor and its Affiliated Obligors were one Obligor. Section 2.4 Maximum Interest Rate.¶ No provision of the Transaction Documents shall require the payment or permit the collection of Interest in excess of the maximum permitted by applicable law. Section 2.5 Payments and Computations, Etc..¶ (a) Payments. All amounts to be paid or deposited by the Borrower or the Servicer (on the Borrower’s behalf) to any of the Agents or Lenders (other than amounts payable under Section 4.2 and other than the proceeds of LC Loans which shall be paid directly to the LC Issuer) shall be paid by wire or electronic transfer of immediately available funds received not later than 1:00 p.m. (New York City time) on the day when due in lawful money of the United States of America to the applicable Co-Agent at its address specified in Schedule 14.2, and, to the extent such payment is for the account of any Lender, the applicable Co-Agent shall promptly disburse such funds to the appropriate Lender(s) in its Group. (b) Late Payments. To the extent permitted by law, upon demand, the Borrower or the Servicer (on the Borrower’s behalf), as applicable, shall pay to the applicable Co-Agent for the account of each Person in its Group to whom payment of any Obligation is due, Interest on all amounts not paid or deposited by 1:00 p.m. (New York City time) on the date when due (without taking into account any applicable grace period) at the Default Rate. (c) Method of Computation. All computations of Interest at the Alternate Base Rate or the Default Rate shall be made on the basis of a year of 365 (or, when appropriate, 366) days for the actual number of days (including the first day but excluding the last day) elapsed. All other computations of Interest, and all computations of Servicer’s Fee, any per annum fees payable under Section 4.1 and any other per annum fees payable by the Borrower to the Lenders, the Servicer or any of the Agents under the Transaction Documents shall be made on the basis of a year of 360 days for the actual number of days (including the first day but excluding the last day) elapsed. (d) Avoidance or Rescission of Payments. To the maximum extent permitted by applicable law, no payment of any Obligation shall be considered to have been paid if at any time such payment is rescinded or must be returned for any reason. (e) No Deduction. All payments to be made by a Loan Party hereunder shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff. 11

(f) Gross-Up. If a Loan Party shall be required by any Requirement of Law to deduct any Taxes from or in respect of any sum payable under any Transaction Document to any Agent or any Lender, (i) in the case of any Taxes other than Excluded Taxes, the sum payable shall be increased as necessary so that after making all required deductions, such Agent or such Lender, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Loan Party shall make such deductions, (iii) such Loan Party shall pay the full amount deducted to the relevant taxation authority or other Governmental Authority in accordance with applicable Requirements of Law, and (iv) within 30 days after the date of such payment, such Loan Party shall furnish to the Administrative Agent (which shall forward the same to such Agent or such Lender) the original or a certified copy of a receipt evidencing payment thereof, to the extent such receipt is issued therefor, or other written proof of payment thereof that is reasonably satisfactory to the Administrative Agent. (g) Taxes – Status of Lenders; Refunds. (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Transaction Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. (ii) Without limiting the generality of the foregoing, (A) any Lender that is a US Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax; (B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable: (1) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Transaction Document, executed copies of IRS Form W-8BEN-E establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Transaction Document, IRS Form W-8BEN-E establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty; (2) executed copies of IRS Form W-8ECI; 12

(3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 871(h) or Section 881(c) of the Code, (x) a “Certificate of Non-Bank Status for Foreign Entities” substantially in the form of Exhibit 3.13(f) to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code and (y) executed copies of IRS Form W- 8BEN-E; or (4) to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, IRS Form W- 8BEN-E, a Certificate of Non-Bank Status for Foreign Entities, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a Certificate of Non-Bank Status for Foreign Entities on behalf of each such direct and indirect partner; (C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and (D) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and (E) on or prior to the execution of this Agreement, and thereafter upon the reasonable request of the Borrower, each Agent (in its capacity as such) shall provide to the Borrower an IRS Form W-8IMY certifying (I) its status as a qualified intermediary, (II) its assumption of primary U.S. federal income tax withholding responsibility for purposes of chapter 3 and chapter 4 of the Code and (III) its assumption of primary IRS Form 1099 reporting and U.S. federal income backup withholding responsibility. Each Lender and Agent agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so. (iii) In the event that an additional payment is made under Section 2.5(f) for the account of any Recipient and such Recipient, in its reasonable judgment, determines that it has finally and irrevocably received or been granted a credit against or release or remission for, or repayment of, any tax 13

paid or payable by it in respect of or calculated with reference to the deduction or withholding giving rise to such payment, such Recipient shall, to the extent that it determines that it can do so without prejudice to the retention of the amount of such credit, relief, remission or repayment, pay to the Borrower such amount as such Recipient shall, in its reasonable judgment, have determined to be attributable to such deduction or withholding and which will leave such Recipient (after such payment) in no worse position than it would have been in if the Borrower had not been required to make such deduction or withholding. Nothing herein contained shall interfere with the right of a Recipient to arrange its tax affairs in whatever manner it thinks fit nor oblige any Recipient to claim any tax credit or to disclose any information relating to its tax affairs or any computations in respect thereof or require any Recipient to do anything that would prejudice its ability to benefit from any other credits, reliefs, remissions or repayments to which it may be entitled. Section 2.6 Non-Receipt of Funds by the Co-Agents.¶ Unless a Lender notifies its Co-Agent prior to the date and time on which it is scheduled to fund a Loan that it does not intend to fund, such Co- Agent may assume that such funding will be made and may, but shall not be obligated to, make the amount of such Loan available to the intended recipient in reliance upon such assumption. If such Lender has not in fact funded its Loan proceeds to the applicable Co-Agent, the recipient of such payment shall, on demand by such Co-Agent, repay to such Co-Agent the amount so made available together with Interest thereon in respect of each day during the period commencing on the date such amount was so made available by such Co-Agent until the date such Co-Agent recovers such amount at a rate per annum equal to the Federal Funds Rate for such day. Section 2.7 Letters of Credit¶. (a) Request for LC Issuance or Modification. Subject to Section 1.1.2, the Borrower shall give the LC Issuer notice prior to 2:00 p.m. (New York City time) at least three (3) Business Days (or such shorter period as may be reasonably acceptable to the LC Issuer) prior to the proposed date of issuance or Modification of each Letter of Credit, by delivering a signed copy of the related LC Application, with appropriate insertions. The issuance or Modification by the LC Issuer of any Letter of Credit shall, in addition to the conditions precedent set forth in Article IV, be subject to the conditions precedent that such Letter of Credit shall be reasonably satisfactory to the LC Issuer and that the Borrower shall have executed and delivered the LC Application and/or such other instruments and agreements relating to such Letter of Credit as the LC Issuer shall have reasonably requested. The LC Issuer shall promptly notify each of the Co-Agents of the request by the Borrower for issuance or Modification of a Letter of Credit hereunder. (b) Letter of Credit Terms. (i) Each Letter of Credit will, among other things, (A) provide for the payment of sight drafts or other written demands for payment when presented for honor thereunder in accordance with the terms thereof and when accompanied by the documents described therein, and (B) have an expiry date not later than twelve (12) months after such Letter of Credit’s date of issuance, extension or renewal, as the case may be, and in no event later than twelve (12) months after the Scheduled Termination Date (or such longer period of time as may be approved in an Email or other writing by each of the LC Issuer and each Group). If the Borrower so requests in any LC Application, the terms of the related Letter of Credit may include customary “evergreen” provisions providing that such Letter of Credit’s expiry date shall automatically be extended for additional periods not to exceed twelve (12) months unless, not less than thirty (30) days (or such longer period as may be specified in such Letter of Credit) (the “Notice Date”) 14

prior to the applicable expiry date, the LC Issuer delivers written notice to the Borrower and the beneficiary thereof declining such extension; provided, however, that if (1) any such extension would cause the expiry date of such Letter of Credit to occur after the date that is twelve (12) months after the Commitment Expiry Date (or such longer period of time as may be approved in an Email or other writing by each of the LC Issuer and the Co-Agents) or (2) the LC Issuer determines that any condition precedent (including, without limitation, those referenced in Section 2.7(a) hereof) to issuing such Letter of Credit hereunder (as if such Letter of Credit were then being first issued) are not satisfied (other than any such condition requiring the Borrower to submit an LC Application in respect thereof), then the LC Issuer, in the case of clause (1) above, may (or, at the written direction of any Committed Lender, shall) or, in the case of clause (2) above, shall, use reasonable efforts in accordance with (and to the extent permitted by) the terms of such Letter of Credit to prevent the extension of such expiry date (including notifying the Borrower and the beneficiary of such Letter of Credit in writing prior to the Notice Date that such expiry date will not be so extended). (ii) Unless the LC Issuer and the Borrower otherwise agree, when a Letter of Credit is issued, it shall be subject to the version of the Uniform Customs and Practice for Documentary Credits in effect at the time of issuance (UCP), or International Standby Practices 1998 (ISP98), at the LC Issuer’s discretion. If such Letter of Credit includes any provision that does not conform to standard Letter of Credit practice, all provisions of this Agreement, including without limitation those relating to reimbursement and indemnification, shall apply to such Letter of Credit. (iii) Notwithstanding anything to the contrary set forth in this Agreement, at the request of the Borrower, a Letter of Credit issued hereunder may contain a statement to the effect that such Letter of Credit is issued for the account of the Servicer or an Affiliate of the Servicer; provided that notwithstanding such statement, the Borrower shall be the actual account party for all purposes of this Agreement for such Letter of Credit, and such statement shall not affect the Borrower’s reimbursement obligations hereunder with respect to such Letter of Credit. (c) Notice of Letter of Credit Request. The Administrative Agent shall promptly notify the LC Issuer and each Committed Lender of the request by the Borrower for a Letter of Credit hereunder. (d) Participations. Immediately upon the issuance by the LC Issuer of any Letter of Credit (or any Modification of a Letter of Credit increasing the amount thereof), the LC Issuer shall be deemed to have sold and transferred to each Committed Lender, and each Committed Lender shall be deemed irrevocably and unconditionally to have purchased and received from the LC Issuer, without recourse or warranty, an undivided interest and participation, to the extent of such Committed Lender’s Ratable Share, in such Letter of Credit, each drawing made thereunder and the obligations of the Borrower hereunder with respect thereto, and any security therefor or guaranty pertaining thereto. Upon any change in the Commitments or Ratable Shares of the Committed Lenders pursuant to this Agreement, it is hereby agreed that, with respect to all outstanding Letters of Credit and unreimbursed drawings thereunder, there shall be an automatic adjustment to the participations pursuant to this Section 2.7(d) to reflect the new Ratable Shares of the assignor and assignee Committed Lender or of all Committed Lenders with Commitments, as the case may be. The Committed Lenders or their Groups will satisfy their funding obligations under this Section 2.7(d) by funding LC Loans pursuant to Section 2.8(a). 15

Section 2.8 Disbursements, Reimbursements and LC Advances.¶ (a) Notice of Drawings; Reimbursement by the Borrower; LC Advances. In the event of any drawing under a Letter of Credit by the beneficiary or transferee thereof that the LC Issuer determines it is legally obligated to honor, the LC Issuer will promptly notify the Borrower and each Co-Agent of such drawing by written notice in the form of Exhibit 2.8(a)-1 (each, a “Draw Notice”). The Borrower shall reimburse the LC Issuer not later than 10:00 a.m. (New York City time) on the Business Day following its receipt of a Draw Notice (such next Business Day, the “Reimbursement Date”) in an amount equal to the amount so paid by the LC Issuer. In the event the Borrower fails to reimburse the LC Issuer for the full amount of any drawing under a Letter of Credit by 10:00 a.m. (New York City time) on the Reimbursement Date, the Borrower will be deemed to have requested that an Advance be made on the Business Day following the applicable Reimbursement Date in a Principal amount equal to such LC Reimbursement Obligation (each such Advance, an “LC Advance”) regardless of whether the Commitment Expiry Date or Termination Date has previously occurred, and the LC Issuer will promptly notify each Co-Agent of such deemed request in writing in the form of Exhibit 2.8(a)-2 hereto (each, an “LC Advance Notice”). (b) LC Advances. Upon receipt of an LC Advance Notice, each applicable Co-Agent shall determine whether its Conduit will fund an LC Loan in an amount equal to the portion of the LC Advance specified in such LC Advance Notice, and (i) PNC severally agrees to make an LC Loan in an amount equal to its Group’s Commitment Percentage of the specified the LC Reimbursement Obligation, on the terms and subject to the conditions hereof, provided that at no time may the aggregate Principal amount of PNC’s Credit Exposure at any one time outstanding exceed the PNC Allocation Limit; (ii) in the event that Gotham elects not to make an LC Loan in an amount equal to its Group’s Commitment Percentage of the specified the LC Reimbursement Obligation, the Gotham Agent shall promptly notify the Borrower and each of the Liquidity Banks in the Gotham Group, and each of such Liquidity Banks severally agrees to make its Pro Rata Share of such LC 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’ Credit Exposure at any one time outstanding exceed the Gotham Allocation Limit; and (iii) in the event that Atlantic elects not to make an LC Loan in an amount equal to its Group’s Commitment Percentage of the specified the LC Reimbursement Obligation, the Atlantic Agent shall promptly notify the Borrower and each of the Liquidity Banks in the Atlantic Group, and each of such Liquidity Banks severally agrees to make its Pro Rata Share of such LC 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’ Credit Exposure at any one time outstanding exceed the Atlantic Allocation Limit. Notwithstanding the fact that LC Loans are being made to the Borrower, all LC Loans shall be disbursed directly to the LC Issuer for application to the specified LC Reimbursement Obligation on the Borrower’s behalf. If any Group fails to make available to the LC Issuer its LC Loan(s) by 10:00am (NY time) on the Business Day after the Reimbursement Date, then Interest shall accrue on the deficient amount from the Reimbursement Date to the date on which such Group fully-funds its LC Loan(s) (i) at a rate per annum equal to the Federal Funds Rate during the first three days following the Reimbursement Date and (ii) at a rate per annum equal to the rate applicable to PNC’s Loans on and after the fourth day following the 16

Reimbursement Date. Each Committed Lender’s obligation to reimburse the LC Issuer for such Committed Lender’s Ratable Share of any drawing under a Letter of Credit issued in accordance with this Agreement shall continue until the last to occur of any of the following events: (A) the occurrence of the Commitment Expiry Date or the LC Issuer otherwise ceases to be obligated to issue or cause to be issued Letters of Credit hereunder; (B) no Letter of Credit issued hereunder remains outstanding and effective; or (C) all Persons (other than the Borrower) have been fully reimbursed for all payments made under or relating to Letters of Credit. Section 2.9 Additional Letter of Credit Provisions; LC Collateral Account¶. (a) The Borrower promises to pay the LC Obligations, together with all LC Fees, LC Fronting Fees and, if applicable, Interest thereon, in accordance with the terms of the Fee Letter and this Section 2.9. (b) Upon receipt by the LC Issuer for its account of immediately available funds from or for the account of the Borrower in excess of PNC’s LC Sublimit Percentage thereof, the LC Issuer shall promptly distribute any excess to the other Co-Agents. (c) If the LC Issuer is required at any time to return to the Borrower, or to a trustee, receiver, liquidator, custodian, or any official in any insolvency proceeding, any portion of the payments made by the Borrower to the LC Issuer pursuant to this Agreement in reimbursement of a payment made under the Letter of Credit or Interest or fee thereon, each Committed Lender shall, on demand of the LC Issuer, forthwith return to the LC Issuer the amount of its Ratable Share of any amounts so returned by the LC Issuer plus Interest at the Federal Funds Rate, from the date the payment was first made to such Committed Lender through, but not including, the date the payment is returned by such Committed Lender. (d) If any Letters of Credit are outstanding and undrawn on the Termination Date, the LC Collateral Account shall be funded from Collections (or by other funds available to the Borrower) in an amount equal to the sum of the Outstanding Face Amount of such Letters of Credit plus Expected LC Fees. (e) Funds in the LC Collateral Account will be used to reimburse the LC Issuer and (to the extent they have unreimbursed LC Advances) the applicable Lenders for due and payable fees related to the Letters of Credit and for any draws on the Letters of Credit and LC Advances which have not reimbursed by the Borrower or repaid from Collections. Any funds on deposit in the ▇▇ ▇▇▇▇ Collateral Account after all Letters of Credit have expired or have been terminated in accordance with their respective terms, all draws on the Letters of Credit have been reimbursed, all LC Advances have been repaid, all fees due and payable with respect to the Letters of Credit have been paid in full, and the Aggregate Commitment has been terminated, shall be remitted to the Borrower. Section 2.10 Documentation and LC Processing Fees¶. The Borrower agrees to be bound by the terms of the LC Application, by the LC Issuer’s commercially reasonable interpretation of any Letter of Credit issued for the Borrower and by the LC Issuer’s customary practices relating to Letters of Credit, though the LC Issuer’s interpretation of such practices may be different from the Borrower’s own. In the event of a conflict between the LC Application and this Agreement, this Agreement shall govern. It is understood and agreed that, except in the case of gross negligence or willful misconduct by the LC Issuer, the LC Issuer shall not be liable for any error, negligence and/or mistakes, whether of omission or commission, in following the Borrower’s instructions or those contained in the Letters of Credit or any 17

modifications, amendments or supplements thereto. In addition to any other fees or expenses owing under the Fee Letter or any other Transaction Documents or otherwise pursuant to any LC Application, the Borrower shall pay to the LC Issuer for its own account any LC Processing Fees. LC Processing Fees shall be due and payable upon demand and shall be nonrefundable. Section 2.11 Determination to Honor Drawing Request¶. In determining whether to honor any request for drawing under any Letter of Credit by the beneficiary thereof, the LC Issuer shall be responsible only to determine that the documents and certificates required to be delivered under such Letter of Credit have been delivered and that they comply on their face with the requirements of such Letter of Credit and that any other drawing condition appearing on the face of such Letter of Credit has been satisfied in the manner so set forth. Section 2.12 Nature of Participation and LC Reimbursement Obligations¶. Each Committed Lender’s obligation in accordance with this Agreement to make LC Loans as a result of an unreimbursed drawing under a Letter of Credit, and the obligations of the Borrower to reimburse the LC Issuer upon a draw under a Letter of Credit, shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Article II under all circumstances, including the following circumstances: (i) any set-off, counterclaim, recoupment, defense or other right which such Committed Lender may have against the LC Issuer, the Administrative Agent, the Co-Agents, the Lenders, the Borrower or any other Person for any reason whatsoever; (ii) the failure of the Borrower or any other Person to comply with the conditions set forth in this Agreement for the making of a purchase, reinvestments, requests for Letters of Credit or otherwise, it being acknowledged that such conditions are not required for the making of LC Advances hereunder; (iii) any lack of validity or enforceability of any Letter of Credit or any set-off, counterclaim, recoupment, defense or other right which Borrower, an Originator or any Affiliate thereof on behalf of which a Letter of Credit has been issued may have against the LC Issuer, the Administrative Agent, any Lender, any Co-Agent or any other Person for any reason whatsoever; (iv) any claim of breach of warranty that might be made by the Borrower, the LC Issuer or any Committed Lender against the beneficiary of a Letter of Credit, or the existence of any claim, set-off, defense or other right which the Borrower, the LC Issuer or any Committed Lender may have at any time against a beneficiary, any successor beneficiary or any transferee of any Letter of Credit or the proceeds thereof (or any Persons for whom any such transferee may be acting), the LC Issuer, any Committed Lender, the Administrative Agent, any Lender or any Co-Agent or any other Person, whether in connection with this Agreement, the transactions contemplated herein or any unrelated transaction (including any underlying transaction between the Borrower or any Subsidiaries of the Borrower or any Affiliates of the Borrower and the beneficiary for which any Letter of Credit was procured); (v) except if the LC Issuer shall have actual knowledge to the contrary: (A) the lack of power or authority of any signer of, or lack of validity, sufficiency, accuracy, enforceability or genuineness of, any draft, demand, instrument, certificate or other document presented under any Letter of Credit, or (B) any such draft, demand, instrument, certificate or other document proving to be forged, fraudulent, invalid, defective or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; 18

(vi) payment by the LC Issuer under any Letter of Credit against presentation of a demand, draft or certificate or other document which does not strictly comply with the terms of such Letter of Credit other than as a result of the gross negligence or willful misconduct of the LC Issuer; (vii) the solvency of, or any acts or omissions by, any beneficiary of any Letter of Credit, or any other Person having a role in any transaction or obligation relating to a Letter of Credit, or the existence, nature, quality, quantity, condition, value or other characteristic of any property or services relating to a Letter of Credit; (viii) any failure by the LC Issuer or any of the LC Issuer’s Affiliates to issue any Letter of Credit in the form requested by the Borrower, unless the LC Issuer has received written notice from the Borrower of such failure within five (5) Business Days after the LC Issuer shall have furnished the Borrower a copy of such Letter of Credit and such error is material and no drawing has been made thereon prior to receipt of such notice; (ix) any Material Adverse Effect; (x) any breach of this Agreement or any Transaction Document by any party thereto; (xi) the occurrence or continuance of an Event of Bankruptcy with respect to the Borrower, any Originator or the Servicer; (xii) the fact that an Event of Default or an Unmatured Default shall have occurred and be continuing; (xiii) the fact that this Agreement or the obligations of the Borrower or Servicer hereunder shall have been terminated; and (xiv) any other circumstances or happening whatsoever, whether or not similar to any of the foregoing, that might otherwise constitute a suretyship defense. Nothing contained in this Section 2.12 shall be deemed to relieve the LC Issuer or the Administrative Agent from any claim by the Borrower for the gross negligence or willful misconduct of the LC Issuer in respect of honoring or failing to honor any drawing under any Letter of Credit or otherwise in respect of any Letter of Credit, but any such claim may not be used as a defense to the Borrower’s obligation to reimburse the LC Issuer for such drawing. Section 2.13 Liability for Acts and Omissions¶. As between the Borrower, on the one hand, and the Administrative Agent, the LC Issuer, the Co-Agents and the Lenders, on the other, the Borrower assumes all risks of the acts and omissions of, or misuse of any Letter of Credit by, the respective beneficiaries of such Letter of Credit. In furtherance and not in limitation of the foregoing, none of the Administrative Agent, the LC Issuer, the Co-Agents or the Lenders shall be responsible for: (i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for an issuance of any such Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged (even if the LC Issuer or any Committed Lender shall have been notified thereof); (ii) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any such Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) the failure of the beneficiary of any such Letter of Credit, or any other party to which 19

such Letter of Credit may be transferred, to comply fully with any conditions required in order to draw upon such Letter of Credit or any other claim of the Borrower against any beneficiary of such Letter of Credit, or any such transferee, or any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any such transferee; (iv) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, electronic mail, cable, telegraph, telex, facsimile or otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under any such Letter of Credit or of the proceeds thereof; (vii) the misapplication by the beneficiary of any such Letter of Credit of the proceeds of any drawing under such Letter of Credit; or (viii) any consequences arising from causes beyond the control of the Administrative Agent, the LC Issuer, the Committed Lenders, the Co-Agents and the Lenders, including any Governmental Acts, and none of the above shall affect or impair, or prevent the vesting of, any of the LC Issuer’s rights or powers hereunder. Nothing contained in the preceding sentence shall relieve the LC Issuer, the Administrative Agent, the Co-Agents or any Lender for such party’s gross negligence, willful misconduct or bad faith (as determined by a court of competent jurisdiction in a final non-appealable judgment) in connection with the actions or omissions described in clauses (i) through (viii) of such sentence, but in no event shall the Administrative Agent, the LC Issuer, the Committed Lenders, the Co-Agents or the Lenders or their respective Affiliates, be liable to the Borrower or any other Person for any indirect, consequential, incidental, punitive, exemplary or special damages or expenses (including without limitation attorneys’ fees), or for any damages resulting from any change in the value of any property relating to a Letter of Credit. Without limiting the generality of the foregoing, the Administrative Agent, the LC Issuer, the Committed Lenders, the Co-Agents and the Lenders and each of its Affiliates (i) may rely on any written communication believed in good faith by such Person to have been authorized or given by or on behalf of the applicant for a Letter of Credit; (ii) may honor any presentation if the documents presented appear on their face to comply with the terms and conditions of the relevant Letter of Credit; (iii) may honor a previously dishonored presentation under a Letter of Credit, whether such dishonor was pursuant to a court order, to settle or compromise any claim of wrongful dishonor, or otherwise, and shall be entitled to reimbursement to the same extent as if such presentation had initially been honored, together with any Interest paid by the LC Issuer or its Affiliates; (iv) may honor any drawing that is payable upon presentation of a statement advising negotiation or payment, upon receipt of such statement (even if such statement indicates that a draft or other document is being delivered separately), and shall not be liable for any failure of any such draft or other document to arrive, or to conform in any way with the relevant Letter of Credit; (v) may pay any paying or negotiating bank claiming that it rightfully honored under the laws or practices of the place where such bank is located; and (vi) may settle or adjust any claim or demand made on the Administrative Agent, the LC Issuer, the Committed Lenders, the Co-Agents or the Lenders or their respective Affiliates, in any way related to any order issued at the applicant’s request to an air carrier, a letter of guarantee or of indemnity issued to a carrier or any similar document (each, an “Order”) and may honor any drawing in connection with any Letter of Credit that is the subject of such Order, notwithstanding that any drafts or other documents presented in connection with such Letter of Credit fail to conform in any way with such Letter of Credit. In furtherance and extension and not in limitation of the specific provisions set forth above, any action taken or omitted by the LC Issuer under or in connection with any Letter of Credit issued by it or any documents and certificates delivered thereunder, if taken or omitted in good faith and without gross negligence or willful misconduct, as determined by a final non-appealable judgment of a court of competent jurisdiction, shall not put the LC Issuer under any resulting liability to the Borrower, any Committed Lender or any other Person. 20

Section 2.14 Intended Tax Treatment¶. All parties to this Agreement covenant and agree to treat any Advance and any drawing on a Letter of Credit under this Agreement as debt for all U.S. federal income tax purposes and to not take any position on any tax return inconsistent with the foregoing, except as otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Code (or any comparable provision of any state, local or foreign law). ARTICLE III. SETTLEMENTS Section 3.1 Reporting.¶ (a) Monthly Reports.¶ Not later than the Monthly Reporting Date in each calendar month hereafter, the Servicer shall deliver to each of the Co-Agents, a Monthly Report accompanied by an electronic file in a form reasonably satisfactory to each of the Co-Agents; provided, however, that if an Unmatured Default or an Event of Default shall exist and be continuing, each of the Co-Agents may request that a computation of the Borrowing Base also be made on a date that is not a Monthly Reporting Date and, so long as such request is not made on or within 5 Business Days prior to the last day of any calendar month, the Servicer agrees to provide such computation within 3 Business Days after such request. (b) [Reserved].¶ (c) Interest; Other Amounts Due¶. At or before 12:00 noon (New York City time) on the Business Day before each Settlement Date, each of the Co-Agents shall notify the Borrower and the Servicer of (i) the aggregate Principal balance of all Loans that are then outstanding from its Constituents, (ii) its Constituents’ LC Sublimit Percentage of the LC Reimbursement Obligations that are then outstanding, and (iii) the aggregate amount of all Principal, Interest and fees that will be due and payable by the Borrower to such Co-Agent for the account of such Co-Agent or its Constituents on such Settlement Date. Section 3.2 Turnover of Collections; Pre-Termination Waterfall¶. Without limiting any Agent’s or ▇▇▇▇▇▇’s recourse to the Borrower for payment of any and all Obligations: (a) If any Monthly Report reveals that a mandatory prepayment or Cash Collateral Payment is required under Section 1.5(b), (c), (d) or (e), not later than the 1:00 p.m. (New York City time) on the next succeeding Settlement Date, the Servicer shall turn over to each applicable Co-Agent, for distribution to its Constituents, a portion of the Collections equal to the amount of such required mandatory prepayment and shall turn over to the LC Issuer for deposit into the LC Collateral Account a portion of the Collections equal to the amount of such required Cash Collateral. (b) If, on any Settlement Date, any Loans are to be voluntarily prepaid in accordance with Section 1.5(a), or if the aggregate Principal amount of the Advances outstanding is to be reduced, the Servicer shall turn over to each of the Co-Agents, for distribution to its Constituents, a portion of the Collections equal to the Groups’ respective Percentages of the aggregate amount of such voluntary prepayment or reduction. (c) In addition to, but without duplication of, the foregoing, on (i) each Settlement Date and (ii) each other date on which any Principal of or Interest on any of the Obligations becomes due (whether by acceleration or otherwise) and, in the case of Principal, has not been reborrowed pursuant to Section 21

1.1 (if permitted), the Servicer shall turn over to each of the Co-Agents, for distribution to their respective Constituents, the Groups’ respective Percentages of a portion of the Collections equal to the aggregate amount of all other Obligations that are due and owing on such date. If the Collections and proceeds of new Loans are insufficient to make all payments required under clauses (a), (b) and (c) and to pay the Servicer’s Fees and, if applicable, all expenses due and owing to any replacement Servicer under Section 8.1(d) (all of the foregoing, collectively, the “Required Amounts”) and the Borrower has made any Demand Advances, the Borrower shall make demand upon Quest Diagnostics for payment of the Demand Advances in an amount equal to the lesser of the Required Amounts or the aggregate outstanding Principal balance of such Demand Advances (plus any accrued and unpaid Interest thereon) and, upon receipt of any such amounts, the Borrower shall pay them to each of the Co-Agents, ratably in accordance with their respective Groups’ Percentages, for distribution in accordance with this Section 3.2. (d) If the aggregate amount of Collections and payments on Demand Advances received by the Co-Agents on any Settlement Date are insufficient to pay all Required Amounts, the aggregate amount received shall be applied to the items specified in the subclauses below, in the order of priority of such subclauses: (i) to any accrued and unpaid Interest on the Loans that is then due and owing, including any previously accrued Interest which was not paid on its applicable due date; (ii) if the Servicer is not the Borrower or an Affiliate thereof, to any accrued and unpaid Servicer’s Fee that is then due and owing to such Servicer, together with any invoiced expenses of the Servicer due and owing pursuant to Section 8.1(d); (iii) to the Unused Fee and the Usage Fee accrued during such Accrual Period, plus any previously accrued Unused Fee and Usage Fee not paid on a prior Settlement Date; (iv) ratably to the payment of the Principal of any Loans that are then due and owing and to the Cash Collateralization of any Non-Renewing Lender’s Share of the LC Obligations; (v) to the payment of LC Processing Fees that are then due and owing. (vi) to other Obligations that are then due and owing; (vii) if the Servicer is the Borrower, Quest Diagnostics or one of their respective Affiliates, to the accrued and unpaid Servicer’s Fee; and (viii) the balance, if any, to the Borrower. (e) If the Servicer is ever required to deliver a computation of the Cash Collateral Payment pursuant to Section 3.1(b), not later than one (1) Business Day after delivery of such computation, the Borrower shall pay to the applicable Co-Agent an amount equal to its Group’s Percentage of the Cash Collateral Payment to be invested in Permitted Investments selected by such Co-Agent but held as Collateral for the Obligations until the next Settlement Date pending distribution in accordance with Section 3.2(d). If the Borrower lacks sufficient funds to make any such Cash Collateral Payment, in whole or in part, the Borrower shall make immediate demand upon Quest Diagnostics for payment of any Demand Advances that are then outstanding, and, upon receipt of any such shortfall amount, the Borrower shall pay each Group’s Percentage of such shortfall amount to the applicable Co-Agent for 22

deposit into a cash collateral account to be invested in Permitted Investments selected by the applicable Co-Agent but held as Collateral for the Obligations until the next Settlement Date pending distribution in accordance with Section 3.2(d). All payments of Principal and Interest made to the Atlantic Group Agent for the account of any Tranched Loan Lender shall be allocated by such Tranched Loan Lender in accordance with Annex C to this Agreement. (f) In addition to, but without duplication of, the foregoing, on (i) each Settlement Date and (ii) each other date on which any Principal of or Interest on any of the Loans becomes due (whether by acceleration pursuant to Section 10.2(a) or 10.2(b) or otherwise), the Servicer shall turn over to each of the Co-Agents, for distribution to the Lenders, a portion of the Collections equal to the aggregate amount of all Obligations that are due and owing on such date. Section 3.3 Non-Distribution of Servicer’s Fee¶. Each of the Agents and the other Secured Parties hereby consents to the retention by the Servicer of a portion of the Collections equal to the Servicer’s Fee (and, if applicable, any invoiced expenses of such Servicer that are due and owing pursuant to Section 8.1(d)) so long as the Collections received by the Servicer are sufficient to pay all amounts pursuant to Section 3.2 of a higher priority as specified in such Section. Section 3.4 Deemed Collections¶. If as of the last day of any Accrual Period: (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: (i) as a result of any rejected services, any cash discount or any other adjustment by the applicable Originator or any Affiliate thereof (regardless of whether the same is treated by such Originator or Affiliate as a write-off), or as a result of any surcharge or other governmental or regulatory action, or (ii) as a result of any setoff or breach of the underlying agreement in respect of any claim by the Obligor thereof (whether such claim arises out of the same or a related or an unrelated transaction), or (iii) on account of the obligation of the applicable Originator or any Affiliate thereof to pay to the related Obligor any rebate or refund, or (iv) the Unpaid Net Balance of any Receivable is less than the amount included in calculating the Net Pool Balance for purposes of any Monthly Report (for any reason other than such Receivable becoming a Defaulted Receivable), or (b) any of the representations or warranties of the Borrower set forth in Section 6.1(j), (l) or (p) was not true when made with respect to any Receivable, or any of the representations or warranties of the Borrower set forth in Section 6.1(l) is no longer true with respect to any Receivable, then, in such event, the Borrower shall be deemed to have received a Collection in an amount equal to (A) the amount of such reduction, cancellation or overstatement, in the case of the preceding clauses (a) (i), (a)(ii), (a)(iii) and (a)(iv), and (B) in the full amount of the Unpaid Net Balance of such Receivable in the case of the preceding clause (b). 23

Section 3.5 Release of Excess Cash Collateral¶. If on any Settlement Date, the balance in the LC Collateral Account exceeds the amount required, unless an Event of Default or an Unmatured Default Event shall exist and be continuing, the LC Issuer shall release the excess cash collateral to the Borrower. ARTICLE IV. FEES AND YIELD PROTECTION Section 4.1 Fees.¶ Quest Diagnostics or the Borrower, as applicable, shall pay to each of the Agents, the LC Issuer and the Lenders certain fees from time to time in amounts and payable on such dates as are set forth in the Fee Letter. Section 4.2 Yield Protection.¶ (a) If any Regulatory Change occurring after the date hereof: (i) shall subject an Affected Party to any Tax, duty or other charge with respect to its Obligations or, as applicable, its Commitment or its Liquidity Commitment, payments to the Affected Party of any Obligations, owed to or funded in whole or in part by it or any other amounts due under this Agreement in respect of its Obligations or, as applicable, its Commitment or its Liquidity Commitment except, in each case, for Taxes other than capital taxes imposed on such Affected Party’s loans, loan principal, Letters of Credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or (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 (iii) shall affect the amount of capital required or expected to be maintained by any Affected Party; or (iv) shall impose any other condition affecting any Obligation owned or funded in whole or in part by any Affected Party, or its rights or obligations, if any, to make Loans or Liquidity Fundings or to issue or participate in Letters of Credit; or (v) shall change the rate for, or the manner in which the Federal Deposit Insurance Corporation (or a successor thereto) assesses deposit insurance premiums or similar charges; or (vi) shall require any Conduit to be consolidated for financial accounting purposes with any other Person; and the result of any of the foregoing is or would be: (x) to increase the cost to or to impose a cost on (I) an Affected Party funding or making or maintaining any Loan, any Liquidity Funding, any Letter of Credit or participation therein, or any commitment of such Affected Party with respect to any of the foregoing, or (II) the LC Issuer, any of the Agents for continuing its or the Borrower’s relationship with any Affected Party, in each case, in an amount deemed to be material by such Affected Party, 24

(y) to reduce the amount of any sum received or receivable by an Affected Party under this Agreement or under the Liquidity Agreement, or (z) to reduce the rate of return on such Affected Party’s capital as a consequence of its Commitment, its Liquidity Commitment, the Letters of Credit or such Affected Party’s participation therein, or the Loans made by it to a level below that which such Affected Party could have achieved but for the occurrence of such circumstances, then, within thirty days after demand by such Affected Party (which demand shall be made not more than 90 days after the date on which the Affected Party obtains actual knowledge of such Regulatory Change and shall be accompanied by a certificate setting forth, in reasonable detail, the basis of such demand and the methodology for calculating, and the calculation of, the amounts claimed by the Affected Party), the Borrower shall pay directly to such Affected Party such additional amount or amounts as will compensate such Affected Party for such actual additional cost, actual increased cost or actual reduction. (b) Each Affected Party will promptly notify the Borrower, the Administrative Agent, the LC Issuer 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. Any Affected Party when making a claim under this Section 4.2 shall submit to the Borrower the above-referenced certificate as to such actual increased cost or actual reduced return (including calculation thereof in reasonable detail), which statement shall, in the absence of demonstrable error, be conclusive and binding upon the Borrower. (d) Each of the Lenders agrees, and shall require each Affected Party to agree that, with reasonable promptness after an officer of such Lender or such Affected Party responsible for administering the Transaction Documents becomes aware that it (x) has become an Affected Party under this Section 4.2, (y) is entitled to receive payments under this Section 4.2, or (z) is or has become subject to U.S. withholding Taxes payable by any Loan Party in respect of its investment hereunder, it will, to the extent not inconsistent with any internal policy of such Person or any applicable legal or regulatory restriction, (i) use all reasonable efforts to make, fund or maintain its commitment or investment hereunder through another branch or office of such Affected Party, or (ii) take such other reasonable measures, if, as a result thereof, the circumstances which would cause such Person to be an Affected Party under this Section 4.2 would cease to exist, or the additional amounts which would otherwise be required to be paid to such Person pursuant to this Section 4.2 would be reduced, or such withholding Taxes would be reduced, and if the making, funding or maintaining of such commitment or investment through such other office or in accordance with such other measures, as the case may be, would not otherwise adversely affect such commitment or investment or the interests of such Person; provided that such Person will not be obligated to utilize such other lending office pursuant to this Section 4.2 unless the Borrower agrees to pay all incremental out-of-pocket expenses incurred by such Person as a result of utilizing such other office as described in clause (i) above. 25

(e) If any Lender makes a claim for compensation under this Section 4.2, the Borrower may propose an Eligible Assignee to the applicable Co-Agent who is willing to accept an assignment of such ▇▇▇▇▇▇’s Commitment, Liquidity Commitment, outstanding Loans and interests in the Letters of Credit, as applicable, together with each of its other rights and obligations under the Transaction Documents; provided that any expenses or other amounts which would be owing to such Lender pursuant to any indemnification provision hereof (including, if applicable, Section 4.3) shall be payable by the Borrower as if the Borrower had prepaid the Loans of the assigning Lenders rather than such assigning ▇▇▇▇▇▇▇ having assigned their respective interests hereunder. 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 all 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 Daily Term SOFR 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. Section 4.4 Inability to Determine Rates¶. Subject to Section 4.6, if, prior to the first day of any Interest Period for any Term SOFR Loan or on any day for any Daily Term SOFR Loan: 26

(i) any applicable Co-Agent determines (which determination shall be conclusive and binding absent manifest error) that “Term SOFR,” “Daily One Month Term SOFR” or “Daily Three Month Term SOFR,” as applicable, cannot be determined pursuant to the applicable definition thereof, or (ii) any applicable Co-Agent determines that for any reason in connection with (x) any request for a Term SOFR Loan or a Daily Term SOFR Loan or a conversion thereto or a continuation thereof or (y) the maintenance of a Daily Term SOFR Loan, that Adjusted Term SOFR for any requested Interest Period with respect to a proposed Term SOFR Loan or the applicable Daily Term SOFR for any day with respect to a Daily Term SOFR Loan does not adequately and fairly reflect the cost to the applicable Lender(s) in its Group of funding such Term SOFR Loan or Daily Term SOFR Loan or maintaining such Daily Term SOFR Loan, as applicable, and such Co-Agent has provided notice of such determination to the Administrative Agent, the Administrative Agent will promptly so notify the Borrower and each Co-Agent. Upon notice thereof by the Administrative Agent to the Borrower, any obligation of the Lenders in such Group to make Term SOFR Loans or to make or maintain Daily Term SOFR Loans, as applicable, and any right of the Borrower to continue Term SOFR Loans or Daily Term SOFR Loans or to convert Alternate Base Rate Loans to Term SOFR Loans or Daily Term SOFR Loans, shall be suspended (to the extent of the affected Term SOFR Loans or affected Interest Periods or affected Daily Term SOFR Loans, as applicable) until the Administrative Agent (with respect to clause (ii), at the instruction of the applicable Co-Agent) revokes such notice. Upon receipt of such notice, (i) the Borrower may revoke any pending request for a borrowing of, conversion to or continuation of Term SOFR Loans or Daily Term SOFR Loans (to the extent of the affected Term SOFR Loans or affected Interest Periods or affected Daily Term SOFR Loans) or, failing that, the Borrower will be deemed to have converted any such request into a request for a Borrowing of or conversion to Alternate Base Rate Loans in the amount specified therein and (ii) any outstanding affected Term SOFR Loans and Daily Term SOFR Loans, as applicable, will be deemed to have been converted into Alternate Base Rate Loans at the end of the applicable Interest Period, in the case of affected Term SOFR Loans, or immediately, in the case of affected Daily Term SOFR Loans. Upon any such conversion, the Borrower shall also pay accrued interest on the amount so converted, together with any additional amounts required pursuant to Section 4.3. Subject to Section 4.6, if an applicable Co-Agent determines (which determination shall be conclusive and binding absent manifest error) that “Term SOFR” cannot be determined pursuant to the definition thereof on any given day, the interest rate on Alternate Base Rate Loans shall be determined by the Administrative Agent without reference to clause (c) of the definition of “Alternate Base Rate” until the Administrative Agent revokes such determination. Section 4.5 Illegality¶. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable lending office to make, maintain or fund Loans whose interest is determined by reference to SOFR, the Term SOFR Reference Rate, Term SOFR, Daily One Month Term SOFR or Daily Three Month Term SOFR (each such Loan, a “SOFR Loan”), or to determine or charge interest rates based upon SOFR, the Term SOFR Reference Rate, Term SOFR, Daily One Month Term SOFR or Daily Three Month Term SOFR, then, upon notice thereof by such Lender to the Borrower (through such Lender’s Co-Agent), (a) any obligation of such Lender to make or maintain a SOFR Loan, and any right of the Borrower to continue SOFR Loans or to convert Alternate Base Rate Loans to SOFR Loans, shall be suspended, and (b) the Alternate Base Rate shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to clause (c) of the definition of “Alternate Base Rate”, in each case until such Lender notifies the Agents and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt 27

of such notice, (i) the Borrower shall, if necessary to avoid such illegality, upon demand from any Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all SOFR Loans to Alternate Base Rate Loans (and the Alternate Base Rate shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to clause (c) of the definition of “Alternate Base Rate”), on the last day of the Interest Period therefor with respect to Term SOFR Loans, if all affected Lenders may lawfully continue to maintain such Term SOFR Loans to such day, or immediately, in the case of Daily Term SOFR Loans or if any Lender may not lawfully continue to maintain such Term SOFR Loans to such day, and (ii) if necessary to avoid such illegality, the Administrative Agent shall during the period of such suspension compute the Alternate Base Rate without reference to clause (c) of the definition of “Alternate Base Rate,” in each case until the Administrative Agent is advised in writing by each affected Lender or its Co-Agent that it is no longer illegal for such Lender to determine or charge interest rates based upon SOFR, the Term SOFR Reference Rate, Term SOFR, Daily One Month Term SOFR or Daily Three Month Term SOFR. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted, together with any additional amounts required pursuant to Section 4.3. Section 4.6 Benchmark Setting¶. (a) Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Transaction Document, upon the occurrence of a Benchmark Transition Event, the Administrative Agent (after consultation with the Co-Agents) and the Borrower may amend this Agreement to replace the then-current Benchmark with a Benchmark Replacement. Any such amendment with respect to a Benchmark Transition Event will become effective at 5:00 p.m. (New York City time) on the fifth (5th) Business Day after the Administrative Agent has posted such proposed amendment to all Co-Agents and the Borrower so long as the Administrative Agent has not received, by such time, written notice of objection to such amendment from any Co-Agent. No replacement of a Benchmark with a Benchmark Replacement pursuant to this Section 4.6(a) will occur prior to the applicable Benchmark Transition Start Date. (b) Benchmark Replacement Conforming Changes. In connection with the use, administration, adoption or implementation of a Benchmark Replacement, the Administrative Agent will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Transaction Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Transaction Document. (c) Notices; Standards for Decisions and Determinations. The Administrative Agent will promptly notify the Borrower and the Lenders of (i) the implementation of any Benchmark Replacement and (ii) the effectiveness of any Conforming Changes in connection with the use, administration, adoption or implementation of a Benchmark Replacement. The Administrative Agent will promptly notify the Borrower of the removal or reinstatement of any tenor of a Benchmark pursuant to Section 4.6(d). Any determination, decision or election that may be made by the Administrative Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 4.6, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement or any other Transaction Document, except, in each case, as expressly required pursuant to this Section 4.6. 28

(d) Unavailability of Tenor of Benchmark. Notwithstanding anything to the contrary herein or in any other Transaction Document, at any time (including in connection with the implementation of a Benchmark Replacement), (i) if the then-current Benchmark is a term rate (including the Term SOFR Reference Rate) and either (A) any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the Administrative Agent in its reasonable discretion or (B) the administrator of such Benchmark or the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is not or will not be representative or in compliance with or aligned with the International Organization of Securities Commissions (IOSCO) Principles for Financial Benchmarks, then the Administrative Agent may modify the definition of “Interest Period”, “Daily One Month Term SOFR” or “Daily Three Month Term SOFR” (or any similar or analogous definition) for any Benchmark settings at or after such time to remove such unavailable, non-representative, non-compliant or non-aligned tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (B) is not, or is no longer, subject to an announcement that it is not or will not be representative or in compliance with or aligned with the International Organization of Securities Commissions (IOSCO) Principles for Financial Benchmarks for a Benchmark (including a Benchmark Replacement), then the Administrative Agent (in consultation with the Borrower) may modify the definition of “Interest Period”, “Daily One Month Term SOFR” or “Daily Three Month Term SOFR” (or any similar or analogous definition) for all Benchmark settings at or after such time to reinstate such previously removed tenor. (e) Benchmark Unavailability Period. Upon the Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrower may revoke any pending request for a borrowing of, conversion to or continuation of SOFR Loans to be made, converted or continued during any Benchmark Unavailability Period and, failing that, the Borrower will be deemed to have converted any such request into a request for a borrowing of or conversion to Alternate Base Rate Loans. For the avoidance of doubt, upon the commencement of a Benchmark Unavailability Period, all outstanding Daily Term SOFR Loans shall be automatically and immediately converted to Alternate Base Rate Loans. During a Benchmark Unavailability Period or at any time that a tenor for the then-current Benchmark is not an Available Tenor, the component of the Alternate Base Rate based upon the then- current Benchmark or such tenor for such Benchmark, as applicable, will not be used in any determination of the Alternate Base Rate. ARTICLE V. CONDITIONS PRECEDENT Section 5.1 [Intentionally Deleted]¶. Section 5.2 Conditions Precedent to All Credit Events¶. Each Credit Event (including the initial Credit Event under this Agreement but excluding the funding of an LC Advance) shall be subject to the conditions precedent that on the applicable Borrowing Date, each of the following statements shall be true (and the Borrower, by accepting the proceeds of any Advance comprising such Credit Event, and each other Loan Party, upon such acceptance by the Borrower, shall be deemed to have certified that): (a) the representations and warranties contained in Section 6.1 are correct in all respects on and as of the date of such Advance as though made on and as of such day and shall be deemed to have been made on such day (except for such representations which speak only as of an earlier date), 29

ARTICLE VI. REPRESENTATIONS AND WARRANTIES Section 6.1 Representations and Warranties of Loan Parties.¶ As of the date hereof and as of the date of each Credit Event, each Loan Party, as to itself, represents and warrants to the Agents and the Lenders as follows: (a) Ownership of the Borrower.

(ii) No Loan Party is in default under any material contract or agreement to which it is a party or by which it is bound, nor, to such Loan Party’s knowledge, does any condition exist that, with notice or lapse of time or both, would constitute such default, excluding in any case such defaults that are not reasonably likely to have a Material Adverse Effect.

(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 Purchased Assets and Quality of Title. (i) Each Purchased Asset 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 Purchased Asset 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 Purchased Asset and the Related Assets.

(i) One of the Loan Parties or the applicable Originator has instructed all Obligors of Private Receivables to pay all Collections thereon either (A) by wire transfer, ACH or other electronic funds transfer directly to a Collection Account in the name of the Borrower that at all times after December 31, 2016 is subject to a Collection Account Agreement, or (B) by mail addressed to a Lockbox that clears each Business Day through a Collection Account in the name of the Borrower that meets the requirements of the preceding clause (A). One of the Loan Parties or the applicable Originator has instructed all Obligors of Specified Government Receivables to pay all Collections thereon either (X) by wire transfer, ACH or other electronic funds transfer directly to a Collection Account in the name, and under the control, of the Originator whose services gave rise thereto which is swept each Business Day into a Collection Account in the name of the Borrower that meets the requirements of clause (A) above, or (Y) by mail addressed to a Lockbox that clears each Business Day through a Collection Account in the name, and under the control, of the Originator whose services gave rise thereto which is swept each Business Day into a Collection Account in the name of the Borrower that meets the requirements of clause (A) above. Each of the agreements establishing and governing the maintenance of the Lockboxes and Collection Accounts is in full force and effect, and at all times after December 31, 2016, each of the Collection Accounts in the name of the Borrower 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. (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, and each Participation Interest included as an Eligible Participation Interest in 34

the Net Pool Balance in connection with any computation or recomputation of the Borrowing Base is an Eligible Participation Interest 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 collectability 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 Purchased Asset 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 Purchased Asset 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 (the “Bankruptcy Code”). (u) ▇▇▇▇▇▇▇ Rule; Investment Company Act; Other Restrictions. Such Loan Party (i) is not a “covered fund” under the ▇▇▇▇▇▇▇ Rule and (ii) is not required to register as, an “investment company” within the meaning of the Investment Company Act of 1940, as amended, or any successor statute. In determining that such Loan Party is not a covered fund, such Loan Party does not rely solely on the exemption from the definition of “investment company” set forth in Section 3(c)(1) and/or 3(c)(7) of the Investment Company Act of 1940. Such Loan Party is not 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. 35

(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. (w) Transaction Information. Such Loan Party and its Affiliates (or any third party with which such Loan Party or any Affiliate thereof has contracted) has not delivered, in writing or orally, to any Rating Agency, any Transaction Information without providing such Transaction Information to the applicable Co-Agent prior to delivery to such Rating Agency and has not participated in any oral communications with respect to Transaction Information with any Rating Agency without the participation of such Co-Agent. (x) Risk Retention. The Originators, individually or through related entities, have collectively retained a material net economic interest in the Receivables in an amount at least equal to the percentage required under, and in a manner permitted by, Paragraph 1 of Article 405 of the European Union Capital Requirements Regulation by reference to the portion of Receivables for which each is the applicable Originator, and have not entered into any credit risk mitigation or any short positions or any other hedge in a manner with respect to such net economic interest, except to the extent permitted by the European Union Risk Retention Requirements. (y) Anti-Corruption Laws and Sanctions. Each Loan Party has implemented and maintains in effect policies and procedures designed to ensure compliance by such Loan Party, its Subsidiaries and their respective directors, officers, employees and agents with Anti-Corruption Laws and applicable Sanctions, and each Loan Party, its Subsidiaries and their respective officers and employees and to the knowledge of such Loan Party its directors and agents are in compliance with Anti-Corruption Laws and applicable Sanctions in all material respects. None of (a) any Loan Party, any Subsidiary or, to the knowledge of such Loan Party, any of their respective directors, officers or employees, or (b) to the knowledge of such Loan Party, any agent of such Loan Party or any Subsidiary that will act in any capacity in connection with or benefit from the credit facility established hereby, is a Sanctioned Person. No Loan or Letter of Credit, use of the proceeds of any Loan or any Letter of Credit or other transaction contemplated by this Agreement will result in a violation by any party hereto of Anti-Corruption Laws or applicable Sanctions. (z) Anti-Corruption Laws. No part of the proceeds of any Loan hereunder will be used directly or indirectly to fund any operations in, finance any investments or activities in or make any payments to, a Sanctioned Person or in any Sanctioned Country in violation of Anti-Corruption Laws or applicable Sanctions. (aa) Liquidity Coverage Ratio. The Borrower has not issued, does not issue and will not issue during the term of this Agreement (i) any obligations that (A) constitute asset-backed commercial paper, or (B) are securities required to be registered under the Securities Act of 1933 (the “33 Act”) or that may be offered for sale under Rule 144A or a similar exemption from registration under the 33 Act or the rules promulgated thereunder, or (ii) any other debt obligations or equity interests other than debt obligations substantially similar to the obligations of the Borrower under this Agreement that are (A) issued to other banks or asset-backed commercial paper conduits in privately negotiated transactions, and (B) subject to transfer restrictions substantially similar to the restrictions on assignment set forth in this Agreement. The Borrower further represents and warrants that its assets and liabilities are consolidated with the assets and liabilities of Quest Diagnostics for purposes of GAAP. 36

(bb) Beneficial Ownership Rule. The Borrower is an entity that is organized under the laws of the United States or of any state thereof and at least 51 percent of whose common stock or analogous equity interest is owned by a Person whose common stock or analogous equity interests are listed on the New York Stock Exchange or the American Stock Exchange or has been designated as a NASDAQ National Market Security listed on the NASDAQ stock exchange and is excluded on that basis from the definition of “Legal Entity Customer” as defined in the Beneficial Ownership Rule.

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; 43

(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.

ARTICLE VIII. 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 all 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 all 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 all of the Co-Agents reasonably determines, in good faith, that such termination is necessary or advisable to protect the Secured Parties’ interests hereunder. 45

(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 and with OPTUM360, 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. Section 8.2 Duties of Servicer¶. (a) Appointment; Duties in General.

(b) Segregation of Collections. The Servicer shall not be required (unless otherwise requested by any of the Agents) to segregate the funds constituting Collections prior to the remittance thereof in accordance with Article III. If instructed by any of the Agents, the Servicer shall segregate Collections and deposit them into the Collateral Account not later than the first Business Day following receipt by the Servicer of such Collections in immediately available funds. (c) Modification of Receivables. Quest Diagnostics, while it is the Servicer, may, in accordance with the Credit and Collection Policy, so long as no Event of Default shall have occurred and be continuing, extend the maturity or adjust the Unpaid Net Balance of any Receivable as Quest Diagnostics may reasonably determine to be appropriate to maximize Collections of the Receivables taken as a whole in a manner consistent with the Credit and Collection Policy (although no such extension or adjustment shall alter the status of such Receivable as a Defaulted Receivable or a Delinquent Receivable or, in the case of an adjustment, limit the rights of the Agents or the Lenders under Section 3.4). 46

(d) Contracts and Records. Each Loan Party shall deliver to the Servicer, and the Servicer shall, or shall direct the Originators as sub-servicers to, hold in trust for the Borrower and the Secured Parties, all Contracts and Records.

The Servicer, if other than Quest Diagnostics or any other Loan Party or Affiliate thereof, shall, as soon as practicable upon demand, deliver to the Borrower all Contracts and other Records in its possession that evidence or relate to receivables of the Borrower other than Receivables, and copies of all Contracts and other Records in its possession that evidence or relate to Receivables, Obligors or Related Assets.

This power of attorney shall automatically terminate as to any Servicer replaced in accordance with Section 8.1(b) and shall automatically transfer to its successor. Section 8.3 Rights of the Agents.¶ (a) Notice to Obligors. At any time when an Event of Default has occurred and is continuing, any of the Agents may notify the Obligors of Purchased Assets, or any of them, of the Borrower’s ownership of the Purchased Assets, and the Administrative Agent’s security interest, for the benefit of the Secured Parties, in the Collateral.

Section 8.4 Responsibilities of Loan Parties.¶ Anything herein to the contrary notwithstanding: (a) Contracts. Each Originator shall remain responsible for performing all of its obligations (if any) under each Contract to the same extent as if no ownership interest or security interests had been conveyed under the Transactions Documents, and the exercise by the Administrative Agent or its designee of its rights and remedies hereunder shall not relieve such Originator from such obligations.

Section 11.5 Notice of Events of Default.¶ None of the Agents shall be deemed to have knowledge or notice of the occurrence of any Event of Default or Unmatured Default unless such Agent has received notice from another Agent, a Lender or a Loan Party referring to this Agreement, stating that an Event of Default or Unmatured Default has occurred hereunder and describing such Event of Default or Unmatured Default. In the event that any of the Agents receives such a notice, it shall promptly give notice thereof to the Lenders and the other Agents. The Administrative Agent shall take such action with respect to such Event of Default or Unmatured Default as shall be directed by any of the Co-Agents provided that the Administrative Agent is indemnified to its satisfaction by such Co-Agent and its Constituent Liquidity Banks against any and all liability, cost and expense which may be incurred by it by reason of taking any such action. Section 11.6 Non-Reliance on Other Agents and Lenders¶. Each of the Lenders expressly acknowledges that none of the Agents, the Structuring Agent nor any of the Agents’ or the Structuring Agent’s respective officers, directors, employees, agents, attorneys-in-fact or affiliates has made any representations or warranties to it and that no act by any of the Agents or the Structuring Agent hereafter taken, including, without limitation, any review of the affairs of the Loan Parties, shall be deemed to constitute any representation or warranty by such Agent or such Structuring Agent, as the case may be. Each of the Lenders also represents and warrants to the Agents, the Structuring Agent and the other Lenders that it has, independently and without reliance upon any such Person (or any of their Affiliates) and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, prospects, financial and other conditions and creditworthiness of the Loan Parties and made its own decision to enter into this Agreement. Each of the Lenders also represents that it will, independently and without reliance upon the Agents, the Structuring Agent or any other Liquidity Bank or Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, prospects, financial and other condition and creditworthiness of the Loan Parties. The Agents, the Structuring Agent, the Lenders and their respective Affiliates, shall have no duty or responsibility to provide any party to this Agreement with any credit or other information concerning the business, operations, property, prospects, financial and other condition or creditworthiness of the Loan Parties which may come into the possession of such Person or any of its respective officers, directors, employees, agents, attorneys-in-fact or affiliates, except that each of the Agents and the Structuring Agent shall promptly distribute to the other Agents, Structuring Agent and the Lenders, copies of financial and other information expressly provided to it by either of the Loan Parties pursuant to this Agreement. Section 11.7 Indemnification of Agents¶. Each Liquidity Bank agrees to indemnify (a) its applicable Co-Agent, (b) the Administrative Agent, and (c) the officers, directors, employees, representatives and agents of each of the foregoing (to the extent not reimbursed by the Loan Parties and without limiting the obligation of the Loan Parties to do so), ratably in accordance with their respective Loans, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including, without limitation, the reasonable fees and disbursements of counsel for such Co-Agent, the Administrative Agent or such Person in connection with any investigative, administrative or judicial proceeding commenced or threatened, whether or not such Co-Agent or the Administrative Agent or such Person shall be designated a party thereto) that may at any time be imposed on, incurred by or asserted against such Co-Agent, the Administrative Agent or such Person as a result of, or arising out of, or in any way related to or by reason of, any of the transactions contemplated hereunder or the execution, delivery or performance of this 55

Agreement or any other document furnished in connection herewith (but excluding any such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting solely from the bad faith, gross negligence or willful misconduct of such Co-Agent, the Administrative Agent or such Person as finally determined by a court of competent jurisdiction). Section 11.8 Agents and LC Issuer in their Individual Capacities¶. Each of the Agents and the LC Issuer in their respective individual capacities and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Loan Parties and their Affiliates as though such Person were not an Agent or the LC Issuer hereunder. With respect to its Loans, if any, pursuant to this Agreement, each of the Agents and the LC Issuer shall have the same rights and powers under this Agreement as any Lender and may exercise the same as though it were not an Agent or the LC Issuer, as the case may be, and the terms “Lender” and “Lenders” shall include each of the Agents and the LC Issuer in their individual capacities. Section 11.9 No Other Duties of Structuring Agent. Anything in this Agreement to the contrary notwithstanding, the Structuring Agent shall have no powers, duties or responsibilities under this Agreement or any of the other Transaction Documents. Section 11.10 Conflict Waivers.

Without limiting the generality of Sections 11.1 and 11.8, each of the Agents and the Lenders hereby acknowledges and consents to any and all CACIB Roles and agrees that in connection with any CACIB Role, CACIB may take, or refrain from taking, any action which it, in its discretion, deems appropriate, , including, without limitation, in its role as administrator of Atlantic, the giving of notice to the Atlantic Liquidity Banks of a mandatory purchase pursuant to the Atlantic Liquidity Agreement, and hereby acknowledges that neither CACIB nor any of its Affiliates has any fiduciary duties hereunder to any Lender (other than Atlantic) arising out of any of the CACIB Roles.

Without limiting the generality of Sections 11.1 and 11.8, each of the Agents and the Lenders hereby acknowledges and consents to any and all MUFG Roles and agrees that in connection with any MUFG Role, MUFG may take, or refrain from taking, any action which it, in its discretion, deems appropriate, including, without limitation, in its role as administrator of Gotham, the giving of notice to the Gotham Liquidity Banks of a mandatory purchase pursuant to the Gotham Liquidity Agreement, and hereby acknowledges that neither MUFG nor any of its Affiliates has any fiduciary duties hereunder to any ▇▇▇▇▇▇ (other than Gotham) arising out of any of the MUFG Roles. Section 11.11 UCC Filings¶. Each of the Secured Parties hereby expressly recognizes and agrees that the Administrative Agent may be listed as the assignee or secured party of record on the various UCC filings required to be made under the Transaction Documents in order to perfect their respective interests in the Collateral, that such listing shall be for administrative convenience only in creating a record or nominee holder to take certain actions hereunder on behalf of the Secured Parties and that such listing will not affect in any way the status of the Secured Parties as the true parties in interest with respect to 56

the Collateral. In addition, such listing shall impose no duties on the Administrative Agent other than those expressly and specifically undertaken in accordance with this Article XI. Section 11.12 Erroneous Payments¶. (a) If the Administrative Agent notifies a Lender or any Person who has received funds on behalf of a Lender (any such Lender or Person, a “Payment Recipient”) that the Administrative Agent has determined in its sole discretion (whether or not after receipt of any notice under immediately succeeding clause (b)) that any funds received by such Payment Recipient from the Administrative Agent or any of its Affiliates were erroneously transmitted to, or otherwise erroneously or mistakenly received by, such Payment Recipient (whether or not known to such Lender or other Payment Recipient on its behalf) (any such funds, whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise, individually and collectively, an “Erroneous Payment”) and demands the return of such Erroneous Payment (or a portion thereof) in writing (provided that, without limiting any other rights or remedies (whether at law or in equity), the Administrative Agent may not make any such demand under this clause (a) with respect to an Erroneous Payment unless such demand is made within 30 days of the date of receipt of such Erroneous Payment by the applicable Payment Recipient), such Erroneous Payment shall at all times remain the property of the Administrative Agent and shall be segregated by the Payment Recipient and held in trust for the benefit of the Administrative Agent, and such Lender shall (or, with respect to any Payment Recipient who received such funds on its behalf, shall cause such Payment Recipient to) promptly, but in no event later than two (2) Business Days thereafter, return to the Administrative Agent the amount of any such Erroneous Payment (or portion thereof) as to which such a demand was made, in same day funds (in the currency so received), together with interest thereon in respect of each day from and including the date such Erroneous Payment (or portion thereof) was received by such Payment Recipient to the date such amount is repaid to the Administrative Agent in same day funds at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation from time to time in effect. A notice of the Administrative Agent to any Payment Recipient under this clause (a) shall be conclusive, absent manifest error. (b) Without limiting the immediately preceding clause (a), each Lender, or any Person who has received funds on behalf of a Lender, hereby further agrees that if it receives a payment, prepayment or repayment (whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise) from the Administrative Agent (or any of its Affiliates) (x) that is in a different amount than, or on a different date from, that specified in a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, (y) that was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates), or (z) that such Lender, or other such recipient, otherwise becomes aware was transmitted, or received, in error or by mistake (in whole or in part) in each case: (i) (A) in the case of immediately preceding clauses (x) or (y), an error shall be presumed to have been made (absent written confirmation from the Administrative Agent to the contrary) or (B) an error has been made (in the case of immediately preceding clause (z)), in each case, with respect to such payment, prepayment or repayment; and (ii) such Lender shall (and shall cause any other recipient that receives funds on its respective behalf to) promptly (and, in all events, within one Business Day of its knowledge of such error) 57

notify the Administrative Agent of its receipt of such payment, prepayment or repayment, the details thereof (in reasonable detail) and that it is so notifying the Administrative Agent pursuant to this Section 11.12(b). (c) Each Lender hereby authorizes the Administrative Agent to set-off, net and apply any and all amounts at any time owing to such Lender under any Transaction Document, or otherwise payable or distributable by the Administrative Agent to such Lender from any source, against any amount due to the Administrative Agent under Section 11.12(a) or under the indemnification provisions of this Agreement. (d) In the event that an Erroneous Payment (or portion thereof) is not recovered by the Administrative Agent for any reason, after demand therefor by the Administrative Agent in accordance with Section 11.12(a), from any Lender that has received such Erroneous Payment (or portion thereof) and/or from any Payment Recipient who received such Erroneous Payment (or portion thereof) on its respective behalf (such unrecovered amount, an “Erroneous Payment Return Deficiency”), upon the Administrative Agent’s notice to such Lender at any time, (i) such Lender shall be deemed to have assigned its Loans, as applicable (but not its corresponding Commitment) with respect to which such Erroneous Payment was made (the “Erroneous Payment Impacted Class”) in an amount equal to the Erroneous Payment Return Deficiency (or such lesser amount as the Administrative Agent may specify) (such assignment of Loans (but not Commitments) of the Erroneous Payment Impacted Class, the “Erroneous Payment Deficiency Assignment”) at par plus any accrued and unpaid interest (with the assignment fee to be waived by the Administrative Agent in such instance), and is hereby (together with the Borrower) deemed to execute and deliver assignment and assumption documentation with respect to such Erroneous Payment Deficiency Assignment, (ii) the Administrative Agent as the assignee Lender shall be deemed to acquire the Erroneous Payment Deficiency Assignment, (iii) upon such deemed acquisition, the Administrative Agent as the assignee Lender shall become a Lender hereunder with respect to such Erroneous Payment Deficiency Assignment and the assigning Lender shall cease to be a Lender hereunder with respect to such Erroneous Payment Deficiency Assignment, excluding, for the avoidance of doubt, its obligations under the indemnification provisions of this Agreement and its applicable Commitment(s) which shall survive as to such assigning Lender and (iv) the Administrative Agent may reflect in the Register its ownership interest in the Loans subject to the Erroneous Payment Deficiency Assignment. The Administrative Agent may, in its discretion, sell any Loans acquired pursuant to an Erroneous Payment Deficiency Assignment to an Eligible Assignee at par subject to the terms and conditions with respect to assignment of Loans set forth herein and upon receipt of the proceeds of such sale, the Erroneous Payment Return Deficiency owing by the applicable Lender shall be reduced by the net proceeds of the sale of such Loan (or portion thereof), and the Administrative Agent shall retain all other rights, remedies and claims against such ▇▇▇▇▇▇ (and/or against any recipient that receives funds on its respective behalf). For the avoidance of doubt, no Erroneous Payment Deficiency Assignment will reduce the Commitment(s) of any Lender and such Commitment(s) shall remain available in accordance with the terms of this Agreement. (e) The parties hereto agree that an Erroneous Payment shall not pay, prepay, repay, discharge or otherwise satisfy any Obligations owed by the Borrower or any other Loan Party, except, in each case, to the extent such Erroneous Payment is, and solely with respect to the amount of such Erroneous Payment that is, comprised of funds received by the Administrative Agent from the Borrower or any other Loan Party for the purpose of reducing the Obligations. 58

(f) To the extent permitted by applicable law, no Payment Recipient shall assert any right or claim to an Erroneous Payment, and hereby waives, and is deemed to waive, any claim, counterclaim, defense or right of set-off or recoupment with respect to any demand, claim or counterclaim by the Administrative Agent for the return of any Erroneous Payment received, including without limitation waiver of any defense based on “discharge for value” or any similar doctrine. (g) Each party’s obligations, agreements and waivers under this Section 11.12 shall survive the resignation or replacement of the Administrative Agent, any transfer of rights or obligations by, or the replacement of, a Lender, the termination of the Commitments and/or the repayment, satisfaction or discharge of all Obligations (or any portion thereof) under any Transaction Document. (h) Nothing referenced in this Section 11.12, including the payment of an Erroneous Payment and the rights and obligations of the parties related thereto under this Section 11.12, shall trigger the Loan Parties’ indemnification obligations hereunder including under Article XIII. ARTICLE XII. ASSIGNMENTS AND PARTICIPATIONS Section 12.1 Restrictions on Assignments, Etc..¶ (a) No Loan Party may assign its rights, or delegate its duties hereunder or any interest herein without the prior written consent of each of the Agents and satisfaction of the Rating Agency Condition; provided, however, that the foregoing shall not be deemed to restrict Quest Diagnostics’ right, prior to delivery of a Successor Notice, to request the Agents’ consent to the appointment of an Affiliate as replacement Servicer (subject to satisfaction of the Rating Agency Condition) or to delegate all or any portion of its duties as Servicer to other Originators, as sub-servicers, so long as Quest Diagnostics remains primarily liable for the performance or non-performance of such duties. (b) Each of the Conduits may, at any time, assign all or any portion of any of its Loans and interests in the Letters of Credit, or sell participations therein, to its Constituent Liquidity Banks (or to its Co-Agent for the ratable benefit of its Constituent Liquidity Banks). (c) In addition to, and not in limitation of, assignments and participations described in Section 12.1(b): (i) In the event that PNC or any of the Liquidity Banks suffers a Downgrading Event, the applicable Co-Agent shall notify the Borrower thereof, and, within 5 Business Days after the Borrower’s receipt of such notice, the Borrower may advise such Co-Agent whether the Borrower intends to replace such Co-Agent’s Group (the “Affected Group”) with a new Group of one or more Eligible Assignees. If the Borrower notifies such Co-Agent that it wishes to effect a replacement, (1) the Lenders in the Affected Group shall promptly execute such assignments as may be reasonably necessary to transfer their rights and obligations to the members of the replacement Group against payment in full of the Affected Group’s Obligations, or (2) if an assignment is not practicable, the parties hereto shall promptly enter into such joinders and amendments to this Agreement as may be reasonably necessary to effect the replacement of the Affected Group with the new Group of one or more Eligible Assignees; (ii) Each of the Lenders may assign all or any portion of its Loans and, if applicable, its Commitment and Liquidity Commitment, to any Eligible Assignee with the prior written consent of (A) 59

the Borrower and (B) such Lender’s applicable Co-Agent, which consents shall not be unreasonably withheld or delayed; (iii) Notwithstanding any other provision of this Agreement to the contrary, each of the Lenders may at any time pledge or grant a security interest in all or any portion of its rights (including, without limitation, rights to payment of Principal and Interest) under this Agreement to secure obligations of such Person to a Federal Reserve Bank located in the United States of America, without notice to or consent of any other party hereto; provided that no such pledge or grant of a security interest shall release such Lender from any of its obligations hereunder or substitute any such pledgee or grantee for such Lender as a party hereto; and (iv) Each of the Lenders may, without the prior written consent of the Borrower or any of the Agents, sell participations in all or any portion of their respective rights and obligations in, to and under the Transaction Documents and the Obligations in accordance with Sections 12.2 and 14.7. (d) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain 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 Commitments of, and principal amounts (and stated interest) of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive (absent manifest error), and the Borrower, the Administrative Agent 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, at any reasonable time and from time to time upon reasonable prior notice. In addition, the Register shall be available for inspection by any Lender as to entries pertaining to it at any reasonable time and from time to time upon reasonable prior notice. Each Lender that sells a participation pursuant to this Agreement shall, acting as a non-fiduciary agent of the Borrower solely for the purpose of maintaining a register in order to satisfy the requirements of Section 5f.103-1(c) of the United States Treasury Regulations, maintain a register on which it records the name and address of each participant to which it has sold a participation and the principal amounts (and stated interest) of each such participant’s interest in the Loans or other rights and obligations of such Lender under this Agreement (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any participant or any information relating to a participant’s interest in any Commitments, Liquidity Commitments, Loans, Letters of Credit or its other obligations under any Transaction Document) except to the extent that such disclosure is necessary to establish that such Commitment, Liquidity Commitment, Loan, Letter of Credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error. Section 12.2 Rights of Assignees and Participants.¶ (a) Upon the assignment by a Lender in accordance with Section 12.1(b) or (c), the Eligible Assignee(s) receiving such assignment shall have all of the rights and obligations of such Lender with respect to the Transaction Documents and the Obligations (or such portion thereof as has been assigned). (b) In no event will the sale of any participation interest in any Lender’s or any Eligible Assignee’s rights under the Transaction Documents or in the Obligations relieve the seller of such 60

participation interest of its obligations, if any, hereunder or, if applicable, under the Liquidity Agreement to which it is a party. Section 12.3 Terms and Evidence of Assignment.¶ Any assignment to any Eligible Assignee(s) pursuant to Section 1.2(c), 12.1(b) or 12.1(c) shall be upon such terms and conditions as the assigning Lender and the applicable Co-Agent, on the one hand, and the Eligible Assignee, on the other, may mutually agree, and shall be evidenced by such instrument(s) or document(s) as may be satisfactory to such Lender, the applicable Co-Agent and the Eligible Assignee(s). Any assignment made in accordance with the terms of this Article XII shall relieve the assigning Lender of its obligations, if any, under this Agreement (and, if applicable, the Liquidity Agreement to which it is a party) to the extent assigned and no Lender may assign or otherwise transfer any of its rights and obligations hereunder except in accordance with the terms of this Article XII. ARTICLE XIII. INDEMNIFICATION Section 13.1 Indemnities by the Borrower.¶ (a) General Indemnity. Without limiting any other rights which any such Person may have hereunder or under applicable law, the Borrower hereby agrees to indemnify each of the Affected Parties, each of their respective Affiliates, and all successors, transferees, participants and assigns and all officers, directors, shareholders, controlling persons, employees and agents of any of the foregoing (each, an “Indemnified Party”), forthwith on demand, from and against any and all damages, losses, claims, liabilities and reasonable related out-of-pocket costs and expenses, including reasonable attorneys’ fees and disbursements (all of the foregoing being collectively referred to as “Indemnified Amounts”) awarded against or incurred by any of them arising out of or relating to the Transaction Documents or the transactions contemplated thereby (including the issuance or Modification of, the fronting for, or any drawing under, any Letter of Credit), the LC Collateral Account, the Obligations or the Collateral, excluding, however: (i) Indemnified Amounts to the extent determined by a court of competent jurisdiction to have resulted from bad faith, gross negligence or willful misconduct on the part of such Indemnified Party, and (ii) recourse (except as otherwise specifically provided in this Agreement) 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 or the related Obligor’s refusal to pay; provided, however, that prior to the occurrence of an Event of Default, the Indemnified Parties shall only be entitled to seek indemnity for the reasonable fees and disbursements of a single law firm as special counsel to all such Indemnified Parties (and, if required, a single law firm as local counsel to all such Indemnified Parties in each relevant jurisdiction where the law firm acting as special counsel is not licensed to practice). Without limiting the foregoing, the Borrower shall indemnify each Indemnified Party for Indemnified Amounts arising out of or relating to: (A) the creation of any Lien on, or transfer by any Loan Party of any interest in, the Collateral other than as provided in the Transaction Documents; (B) any representation or warranty made by any Originator or Loan Party (or any of its officers) under or in connection with any Transaction Document, any Monthly Report or any other information or report delivered by or on behalf of any Originator or 61

Loan Party pursuant thereto, which shall have been false, incorrect or misleading in any respect when made or deemed made or delivered, as the case may be; (C) the failure by any Loan Party to comply with any applicable law, rule or regulation with respect to any Receivable or the related Contract and/or Invoice, including, without limitation, any state or local assignment of claims act or similar legislation prohibiting or imposing notice and acknowledgement requirements or other limitations or conditions on the sale of participations in a Specified Government Receivable, or the nonconformity of any Receivable or the related Contract and/or Invoice with any such applicable law, rule or regulation; (D) the failure to vest and maintain vested in the Borrower a perfected ownership interest in all Collateral; or the failure to vest and maintain vested in the Administrative Agent, for the benefit of the Secured Parties, a valid and perfected first priority security interest in the Collateral, free and clear of any other Lien, other than a Lien arising solely as a result of an act of one of the Secured Parties, now or at any time thereafter; (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; (G) any matter described in Section 3.4; (H) any failure of any Loan Party, as the Borrower, the Servicer or otherwise, to perform its duties or obligations in accordance with the provisions of this Agreement or the other Transaction Documents to which it is a party; (I) any claim of breach by any Loan Party of any related Contract and/or Invoice with respect to any Receivable; (J) any Other Taxes (and all interest and penalties thereon or with respect thereto, and all out-of-pocket costs and expenses, including the reasonable fees and expenses of counsel in defending against the same), which may arise by reason of the Administrative Agent’s security interest in the Collateral; (K) the commingling of Collections of Receivables at any time with other funds; 62

(L) any investigation, litigation or proceeding related to or arising from this Agreement or any other Transaction Document, the transactions contemplated hereby or thereby, the use of the proceeds of any Loan, the issuance of any Letter of Credit, the security interest in the Purchased Assets and Related Assets or any other investigation, litigation or proceeding relating to the Borrower or any of the Originators in which any Indemnified Party becomes involved as a result of any of the transactions contemplated hereby or thereby (other than an investigation, litigation or proceeding (1) relating to a dispute solely amongst the Lenders (or certain Lenders) and the Administrative Agent or (2) excluded by Section 13.1(a)); (M) any products or professional liability, personal injury or damage suit, or other similar claim arising out of or in connection with merchandise, insurance or services that are the subject of any Contract, Invoice or any Purchased Asset; (N) any inability to litigate any claim against any Obligor in respect of any Receivable as a result of such Obligor being immune from civil and commercial law and suit on the grounds of sovereignty or otherwise from any legal action, suit or proceeding; (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 Private Receivables owing from any single Obligor and its Affiliated Obligors which causes the aggregate Unpaid Net Balance of all such Private Receivables to exceed the applicable Obligor Concentration Limit; or (Q) any amount that the Administrative Agent is required to pay to any Collection Bank pursuant to the terms of a Collection Account Agreement because of the Borrower’s failure to make such payment. (b) Contest of Tax Claim; After-Tax Basis¶. If any Indemnified Party shall have notice of any attempt to impose or collect any Tax or governmental fee or charge for which indemnification will be sought from any Loan Party under Section 13.1(a)(J), such Indemnified Party shall give prompt and timely notice of such attempt to the Borrower and the Borrower shall have the right, at its expense, to participate in any proceedings resisting or objecting to the imposition or collection of any such Tax, governmental fee or charge. Indemnification hereunder shall be in an amount necessary to make the Indemnified Party whole after taking into account any tax consequences when actually realized by the Indemnified Party of the payment of any of the aforesaid taxes or payments of amounts indemnified against hereunder (including any deduction) and the receipt of the indemnity payment provided hereunder or of any refund of any such tax previously indemnified hereunder, including the effect of such tax, amount indemnified against, deduction or refund on the amount of tax measured by net income or profits which is or was payable by the Indemnified Party. 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. 63

(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 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 13.3 FATCA¶.

Section 14.14 Business Associate Agreement; Health Care Data Privacy and Security Requirements.¶ (a) Definitions. “HIPAA” means the Health Insurance Portability and Accountability Act of 1996. The terms “▇▇▇ ▇▇▇▇,” “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 70

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 sub-contractors 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 71

based upon, arising out of or attributable to the acts or omissions of such Business Associate, its employees, officers, directors, agents, or sub-contractors 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 any 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 other senior Indebtedness and its Liquidity Banks. Section 14.17 PATRIOT Act.¶ Each Lender that is subject to the requirements of the Act hereby notifies the Loan Parties that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies the Loan Parties, the Originators and their respective Subsidiaries, which information includes the name and address of the Loan Parties, the Originators and their respective 72

Subsidiaries and other information that will allow such Lenders to identify such parties in accordance with the Act. Section 14.18 Defaulting Lenders¶. (a) If any Committed Lender becomes a Defaulting Lender at any time when there are undrawn Letters of Credit outstanding, then all or any part of such Defaulting Lender’s participation in such Letters of Credit shall be reallocated among the Committed Lenders that are not Defaulting Lenders in accordance with their respective Ratable Shares (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that (i) the conditions precedent to Credit Events are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (ii) such reallocation does not cause the Credit Exposure of any Lender to exceed such Lender’s applicable Commitment. Subject to Section 1.9, no such reallocation shall constitute a waiver or release of any claim of any party against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of any other Lender as a result of such other ▇▇▇▇▇▇’s increased Credit Exposure following such reallocation. (b) If any Committed Lender becomes a Defaulting Lender at any time when there are Advances outstanding, then all or any part of such Defaulting Lender’s Loans shall be reallocated among the Committed Lenders that are not Defaulting Lenders in accordance with their respective Ratable Shares (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that (i) the conditions precedent to Credit Events are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (ii) such reallocation does not cause the Credit Exposure of any Lender to exceed such ▇▇▇▇▇▇’s Commitment. No such reallocation shall constitute a waiver or release of any claim of any party against a Defaulting Lender arising from that ▇▇▇▇▇▇ having become a Defaulting Lender, including any claim of any other Lender as a result of such other ▇▇▇▇▇▇’s increased Credit Exposure following such reallocation. (c) If any Committed Lender becomes a Defaulting Lender at any time when there are undrawn Letters of Credit or Advances outstanding and the reallocation described in the paragraph above cannot, or can only partially, be effected, then the Borrower shall (i) within two (2) Business Days following notice by the LC Issuer or the Administrative Agent, (A) cash collateralize for the benefit of the LC Issuer a portion of the amount of the then outstanding Letters of Credit equal to such Defaulting Lender’s Ratable Share (determined after giving effect to any reallocation of its participation in Letters of Credit pursuant to clause (a) above) of such undrawn stated amount of outstanding Letters of Credit by depositing such amount into the LC Collateral Account, and/or (B) reduce the outstanding Principal balance of the Loans of the other Lenders in an aggregate amount, and (ii) maintain funds in the LC Collateral Account to cash collateralize such Defaulting Lender’s Ratable Share (determined after giving effect to any reallocation of its participation in Letters of Credit pursuant to clause (a) above) of undrawn stated amount of outstanding Letters of Credit. The Administrative Agent shall apply funds deposited into the LC Collateral Account to satisfy a Defaulting Lender’s obligation to fund its portion of a Reimbursement Advance requested or deemed requested by the Borrower and to fund any LC Advance required to be made by such Defaulting Lender. (d) The Borrower shall not be required to pay such Defaulting Lender any fees payable with respect to the amount of the undrawn Letters of Credit that is so Cash Collateralized by the Borrower. 73

(e) No amount payable by the Borrower for the account of a Defaulting Lender (whether on account of Principal, Interest, indemnity payments or other amounts) shall be paid or distributed to such Defaulting Lender (or its Co-Agent), but instead shall be deposited to the LC Collateral Account until the amount therein is equal to the amount of such Defaulting Lender’s Pro Rata Share of the stated amount of the undrawn Letters of Credit that is not cash collateralized, and to the extent of any remaining amounts, to pay to such Defaulting Lender amounts owed to it.
