UNLESS OTHERWISE INDICATED, CAPITALIZED TERMS USED IN THIS AGREEMENT ARE DEFINED IN ANNEX A. 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 (i) sold and/or contributed, and hereafter will sell to the Borrower, all of such Originator's right, title and interest in and to its private accounts receivable and certain related rights and (ii) pledged to the Borrower and its assigns certain non-assignable contracts related thereto; WHEREAS, the Borrower has requested that the Lenders make revolving loans to the Borrower from time to time hereafter secured by the Collateral, and, subject to the terms and conditions contained in this Agreement, Blue Ridge is willing to make such secured loans on an uncommitted basis, and the Liquidity Banks are willing to make such secured loans on a committed basis; WHEREAS, the Lenders have requested that Quest Diagnostics act as the initial Servicer for the Collateral, and, subject to the terms and conditions contained in this Agreement, Quest Diagnostics is willing to act in such capacity; PROVIDED, HOWEVER, that Quest Diagnostics has advised the Administrative Agent and the Lenders that it may wish to designate an alternate Affiliate to serve as the 6 Servicer, subject to approval of the Administrative Agent and to satisfaction of the Rating Agency Condition, and WHEREAS, Wachovia has been requested, and is willing, to act as the Administrative Agent under this Agreement. NOW, THEREFORE, in consideration of the premises and the mutual agreements herein contained, the parties hereto hereby agree as follows: ARTICLE I THE CREDIT Section 1.1 THE FACILITY. On the terms and subject to the conditions set forth in this Agreement, the Borrower (or the Servicer, on the Borrower's behalf) may from time to time during the Revolving Period request Advances by delivering a Borrowing Request to the Administrative Agent in accordance with Section 2.1. Upon receipt of a copy of each Borrowing Request from the Borrower (or the Servicer, on the Borrower's behalf), the Administrative Agent shall determine whether Blue Ridge will fund all or any portion of the requested Advance, and in the event that Blue Ridge elects not to make all or any part of such Advance, the Administrative Agent shall promptly notify the Borrower and, unless the Borrower cancels its Borrowing Request, each of the Liquidity Banks severally agrees to make its Ratable Share of such Advance to the Borrower, on the terms and subject to the conditions hereof, PROVIDED THAT at no time may the aggregate principal amount of the Advances at any one time outstanding exceed the lesser of the Aggregate Commitment and the Borrowing Base (such lesser amount, the "ALLOCATION LIMIT"). Each Advance shall be in the minimum amount of $1,000,000 or a larger integral multiple of $500,000. All Liquidity Banks' Commitments to make Loans hereunder shall terminate on the Termination Date. Each of the Loans, and all other Obligations of the Borrower, shall be secured by the Collateral as provided in Article IX. Section 1.2 RATABLE LOANS; FUNDING MECHANICS; LIQUIDITY FUNDINGS. (a) Each Advance hereunder shall consist of one or more Loans made by Blue Ridge and/or the Liquidity Banks. (b) Each Lender funding any Loan shall wire transfer the principal amount of its Loan to the Administrative 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, the Administrative Agent shall wire transfer such funds to the account specified by the Borrower in its Borrowing Request not later than 2:00 p.m. (New York City time) on such Borrowing Date. (c) While it is the intent of Blue Ridge to fund each requested Advance through the issuance of one or more tranches of Commercial Paper Notes, the parties acknowledge that if Blue Ridge 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, Blue Ridge may put all or any portion of its Loans to the 7 Liquidity Banks at any time pursuant to the Liquidity Agreement to finance or refinance the necessary portion of its Loans through a Liquidity Funding to the extent available. The Liquidity Fundings may be Alternate Base Rate Loans or Eurodollar Loans, or a combination thereof, selected by the Borrower in accordance with Article II. 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. 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. (d) Nothing herein shall be deemed to commit any Lender to make CP Rate Loans. Section 1.3 INTEREST RATES. (a) Each CP Rate Loan shall bear interest on the outstanding principal amount thereof from and including the first day of the CP Tranche Period applicable thereto selected in accordance with Article II of this Agreement to (but not including) the last day of such CP Tranche Period at the applicable CP Rate. (b) Each Eurodollar Loan shall bear interest on the outstanding principal amount thereof from and including the first day of the Interest Period applicable thereto selected in accordance with Article II of this Agreement to (but not including) the last day of such Interest Period at a rate PER ANNUM equal to the sum of (i) the applicable Eurodollar Rate (Reserve Adjusted) for such Interest Period plus (ii) the Applicable Margin PER ANNUM. (c) Each Alternate Base Rate Loan shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Loan is made to but excluding the date it is paid in full at a rate PER ANNUM equal to the Alternate Base Rate for such day. Changes in the rate of interest on Alternate Base Rate Loans will take effect simultaneously with each change in the Alternate Base Rate. (d) Notwithstanding anything to the contrary contained in Sections 1.3(a), (b) or (c), upon the occurrence of an Event of Default, and during the continuance thereof, all Obligations shall bear interest, payable upon demand, at the Default Rate. (e) Interest shall be payable for the day a Loan is made but not for the day of any payment on the amount paid if payment is received prior to noon (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. 8 Section 1.4 PAYMENT DATES; NOTELESS AGREEMENT. (a) The Borrower promises to pay each CP Rate Loan on the last day of its CP Tranche Period. (b) The Borrower promises to pay each Eurodollar Loan on the last day of its Interest Period. (c) The Borrower promises to pay each Alternate Base Rate Loan, together with all accrued and unpaid interest thereon, on or before the earlier to occur of (i) the Termination Date, and (ii) the refinancing of such Loan with a CP Rate Loan or a Eurodollar Rate Loan. (d) The Borrower promises to pay all accrued and unpaid interest on each Loan on its applicable Interest Payment Date(s). (e) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. Upon request of the Borrower or the Administrative Agent, such Lender will confirm the outstanding principal balances of its Loans and the amount of any accrued and unpaid interest thereon. The entries maintained in the accounts maintained pursuant to this Section shall be PRIMA FACIE evidence of the existence and amounts of the Obligations therein recorded; PROVIDED, HOWEVER, that the failure of any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms. (f) If the Administrative Agent is required to make any indemnity payment or reimbursement to any Collection Bank pursuant to a Collection Account Agreement, the Borrower will reimburse the Administrative Agent for the amount of such payment or reimbursement not later than the next Settlement Date, and the Borrower's obligations hereunder shall constitute part of the Obligations and shall be secured by the Collateral. Section 1.5 PREPAYMENTS. Subject, in the case of CP Rate Loans and Eurodollar Loans, to the funding indemnification provisions of Section 4.3: (a) The Borrower may from time to time voluntarily prepay, without penalty or premium, all outstanding Advances, or, in a minimum aggregate amount of $2,000,000 (or a larger integral multiple of $1,000,000), any portion of the outstanding Advances by written notice to the Administrative Agent (each, a "PREPAYMENT NOTICE") given within the Required Notice Period, PROVIDED that each such prepayment of principal is accompanied by a payment of all accrued and unpaid interest thereon and is made ratably amongst the Lenders; and (b) If on any Business Day, the aggregate outstanding principal amount of the Advances (whether funded by Blue Ridge or through Liquidity Fundings) exceeds the Allocation Limit, the Borrower shall prepay the Advances by wire transfer to the Administrative Agent received not later than 12:00 noon (New York City time) on the first Business Day thereafter of 9 an amount sufficient to eliminate such excess, together with accrued and unpaid interest on the amount prepaid. Upon receipt of any wire transfer pursuant to Section 1.5(a) or (b), the Administrative Agent shall wire transfer to the Lenders their respective shares thereof not later than 1:00 p.m. (New York City time) on the date when received. Any prepayment required pursuant to Section 1.5(b) shall be applied first, to the ratable reduction of any Alternate Base Rate Loans outstanding, second, to the ratable reduction of any Eurodollar Loans outstanding, and last, to the reduction of CP Rate Loans selected by the Borrower (or the Servicer, on the Borrower's behalf). Section 1.6 REDUCTIONS IN AGGREGATE COMMITMENT. The Borrower may permanently reduce the Aggregate Commitment in whole or 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 Administrative Agent (each, a "COMMITMENT REDUCTION NOTICE"), which notice shall specify the aggregate amount of any such reduction; PROVIDED, HOWEVER, that (a) the amount of the Aggregate Commitment may not be reduced below the aggregate principal amount of the outstanding Advances, and (b) the Aggregate Commitment may not be reduced below $25,000,000 unless it is terminated in full. All accrued and unpaid fees shall be payable on the effective date of any termination of the Aggregate Commitment. Each Commitment Reduction Notice shall be irrevocable once delivered to the Administrative Agent. Section 1.7 REQUESTS FOR INCREASES IN AGGREGATE COMMITMENT. (a) Subject to Section 1.7(b) below: (i) the Borrower may from time to time request increases in the Aggregate Commitment in a minimum amount of $10,000,000 (or a larger integral multiple of $1,000,000), upon at least 30 days' (or such lesser time as the Administrative Agent may approve) prior written notice to the Administrative Agent specifying the amount of and proposed effective date for any such requested increase (each, a "COMMITMENT INCREASE REQUEST"); (ii) if (A) with respect to any request to increase the Aggregate Commitment up to $350,000,000, the Administrative Agent and each directly affected Liquidity Bank, or (B) with respect to any request to increase the Aggregate Commitment in excess of $350,000,000, the Administrative Agent and all of the Liquidity Banks, agree to the requested increase by notifying the Borrower in writing of their concurrence, then such adjustments shall be made to the Commitments of the Liquidity Banks, ratably in accordance with their respective Ratable Shares, as of the effective date specified in the Commitment Increase Request, and (iii) if (A) with respect to any request to increase the Aggregate Commitment up to $350,000,000, the Administrative Agent and each directly affected Liquidity Bank, or (B) with respect to any request to increase the Aggregate Commitment in excess of $350,000,000, the Administrative Agent or any Liquidity Bank declines such request, the amount of the Aggregate Commitment shall remain the same. (b) Notwithstanding the foregoing, if any increase in the Aggregate Commitment is requested prior to September 30, 2000, the Loan Parties acknowledge that on September 30, 2000, Wachovia's Commitment shall automatically reduce to $225,000,000, and that the first $31,000,000 of such new Lenders' 10 Commitments will reduce Wachovia's Commitment on a dollar-for-dollar basis, and thereafter, 50% of such new Lenders' Commitments will reduce Wachovia's Commitment (until such time as it is reduced to $150,000,000), and the remainder will increase the Aggregate Commitment until it reaches $350,000,000. If one or more new Lenders joins this Agreement after September 30, 2000, 50% of such new Lenders' Commitments will reduce Wachovia's Commitment (until such time as it is reduced to $150,000,000), and the remainder will increase the Aggregate Commitment until it reaches $350,000,000. Section 1.8 EXTENSION OF THE SCHEDULED TERMINATION DATE. Provided that no Unmatured Default or Event of Default exists and is continuing, the Borrower may request an extension of the Scheduled Termination Date by submitting a request for an extension (each, an "EXTENSION REQUEST") to the Administrative Agent no more than 210 days prior to the Scheduled Termination Date then in effect, together with a fully-earned and non-refundable fee of $5,000 (the "EXTENSION REQUEST FEE"). Each Extension Request must specify the new Scheduled Termination Date requested by the Borrower and the date (which must be at least 30 days after the Extension Request is delivered to the Administrative Agent) as of which the Administrative Agent and the Liquidity Banks must respond to the Extension Request (the "RESPONSE DATE"). The new Scheduled Termination Date shall be no more than 364 days after the Response Date, including the Response Date as one of the days in the calculation of the days elapsed. Promptly upon receipt of an Extension Request and the Extension Request Fee, the Administrative Agent shall notify the Lenders of the contents thereof and shall request each Lender to approve the Extension Request. Each Lender approving the Extension Request shall deliver its written approval to the Administrative Agent no later than the Response Date, whereupon the Administrative Agent shall notify the Borrower within one (1) Business Day thereafter as to whether all of the Lenders have approved the Extension Request. If all of the Lenders have approved the Extension Request, the Scheduled Termination Date specified in the Extension Request shall become effective on such Response Date, and the Administrative Agent shall promptly notify the Borrower and the Lenders of the new Scheduled Termination Date. If any Liquidity Bank does not agree to an Extension Request, the Scheduled Termination Date shall not be extended for such Liquidity Bank, and the Borrower shall have the right to require such Liquidity Bank to assign all, but not less than all, of its Commitment and outstanding Obligations by entering into an assignment with one or more Eligible Assignees in accordance with the provisions of Section 12.1(c), to which the extended Scheduled Termination Date shall apply. Each such assignment to an Eligible Assignee shall become effective on the date set forth in the applicable assignment agreement, and subject to receipt of payment in full on such existing Scheduled Termination Date for all such Obligations, the non-extending Lender shall make such assignment. In the event that no Eligible Assignee is identified that is willing to accept an assignment of the Commitment and Obligations of a Liquidity Bank that does not agree to an Extension Request, such Liquidity Bank's Commitment will terminate on the existing Scheduled Termination Date and the Aggregate Commitment will be reduced by such amount on such date. Section 1.9 DISTRIBUTION OF CERTAIN NOTICES; NOTIFICATION OF INTEREST RATES. Promptly after receipt thereof, the Administrative Agent will notify the Lenders of the contents of each Monthly Report, Weekly Report, computation of Cash Collateral Payment, Borrowing Request, Extension Request, Commitment Reduction Notice, Prepayment Notice, Commitment Increase Request or notice of default received by it from the Borrower or the Servicer hereunder. 11 In addition, the Administrative Agent shall promptly notify the applicable Lenders and the Borrower of each determination of and change in Interest Rates. ARTICLE II BORROWING AND PAYMENT MECHANICS; CERTAIN COMPUTATIONS Section 2.1 METHOD OF BORROWING. The Borrower (or the Servicer, on the Borrower's behalf) shall give the Administrative Agent irrevocable notice in the form of Exhibit 2.1 hereto (each, a "BORROWING REQUEST") not later than 12:00 noon (New York City time) at least two (2) Business Days before the Borrowing Date of each Advance. On each Borrowing Date, each Lender shall make available its Loan or Loans in immediately available funds to the Administrative 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, the Administrative Agent will wire transfer the funds so received from the Lenders to the Borrower at the account specified in its Borrowing Request not later than 2:00 p.m. (New York City time) on the applicable Borrowing Date. Unless the Administrative Agent in its sole discretion shall otherwise agree, not more than one (1) Borrowing Date shall occur 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, the Borrower (or the Servicer, on the Borrower's behalf) in its Borrowing Request may request CP Tranche Periods (or, in the case of Liquidity Fundings, Interest Periods) from time to time to apply to each Lender's CP Rate Loans or Eurodollar Loans, as applicable; PROVIDED, HOWEVER, that (i) at least one CP Tranche Period or one Interest Period shall mature on each Settlement Date, and (ii) no CP Tranche Period or Interest Period which began prior to the Scheduled Termination Date shall extend beyond the Scheduled Termination Date. (b) While, except during the continuance of an Event of Default, the Administrative Agent will use reasonable efforts to accommodate the Borrower's or the Servicer's requests for CP Tranche Periods or Interest Periods, the Administrative Agent shall have the right to subdivide any requested Advance into one or more Loans of different CP Tranche Periods or Interest Periods, as the case may be, or, if the requested period is not feasible, to suggest an alternative CP Tranche Period or Interest Period, PROVIDED THAT not less than $1,000,000 of principal may be allocated to any CP Tranche Period or Interest Period of any Lender, and no Alternate Base Rate Loan may have a principal amount of less than $1,000,000. (c) The Borrower (or the Servicer, on the Borrower's behalf) may not request an Interest Period for a Eurodollar Loan unless it shall have given the Administrative Agent written notice of its desire therefor not later than 12:00 noon (New York City time) at least three (3) Business Days prior to the first day of the desired Interest Period.

Section 3.3 NON-DISTRIBUTION OF SERVICER'S FEE. Each of the Administrative Agent 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.

If as of the last day of any Settlement Period: 16 (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).

(f) Each Affected Party will promptly notify the Borrower and the Administrative 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. (g) 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.

(i) If any Liquidity Bank makes a claim for compensation under this Section 4.2, the Borrower may propose an Eligible Assignee to the Administrative Agent who is willing to accept an assignment of such Liquidity Bank's Commitment, Liquidity Commitment and outstanding Loans, 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 Liquidity Bank 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 Lenders having assigned their respective interests hereunder. If such proposed Eligible Assignee is acceptable to the Administrative Agent (who shall not unreasonably withhold or delay its approval), the claiming Liquidity Bank will be obligated to assign all of its rights and obligations to such proposed Eligible Assignee within ten (10) Business Days after the Administrative Agent gives its consent to such proposed Eligible Assignee. Section 4.3 FUNDING LOSSES.

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.

The projections and pro forma financial information furnished at any time by any Loan Party to any Lender pursuant to this Agreement have been prepared in good faith based on assumptions believed by Quest Diagnostics to be reasonable at the time made, it being recognized by the Lenders that such financial information as it relates to future events is not to be viewed as fact and that actual results during the period or periods covered by such financial information may differ from the projected results set forth therein by a material amount and no Loan Party, however, makes any representation as to the ability of any Loan Party to achieve the results set forth in any such projections. 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, 1999 through and including the date of the initial Advance, there has been no material adverse change in Quest Diagnostics' consolidated financial condition, business or operations. Since the date of the initial Advance, there has been no material adverse change in Quest Diagnostics' consolidated financial condition, business or operations that has had, or would reasonably be expected to have, a material adverse effect upon its ability to perform its obligations, as an Originator or as Servicer, under the Transaction Documents when and as required, and no material adverse effect on the collectibility of any material portion of the Receivables. (iii) Since the date of the initial Advance, no event has occurred which would have a Material Adverse Effect. (j) NATURE OF RECEIVABLES. Each Receivable constitutes an "Account" or a "General Intangible" and is not are not an "interest or claim in or under any policy of insurance" within the meaning of 9-104(g) of the New York UCC. (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. 26 (l) TITLE TO RECEIVABLES AND QUALITY OF TITLE. (i) Each Receivable has been acquired by the Borrower from an Originator in accordance with the terms of the Sale Agreement, and the Borrower has thereby irrevocably obtained all legal and equitable title to such Receivable and its Related Assets (other than any Related Asset constituting a Non-Assignable Contract, in which case the Borrower has obtained a valid and perfected first priority perfected security interest in the rights to receive payments thereunder), and the Borrower has the legal right to sell and encumber, such Receivable and the Related Assets. Without limiting the foregoing, there have been duly delivered to the Administrative Agent in form suitable for filing all financing statements or other similar instruments or documents necessary under the UCC of all appropriate jurisdictions to perfect the Borrower's ownership interest in such Receivable. (ii) This Agreement creates a valid security interest in the Collateral in favor of the Administrative Agent, for the benefit of the Secured Parties, and, upon filing of the financing statements described in clause (i), together with UCC termination statements delivered under the Receivables Sale Agreement, such security interest will be a first priority perfected security interest. (iii) No financing statement 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 the Administrative Agent hereunder. (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 the Administrative Agent or Lenders pursuant to this Agreement was or will be inaccurate in any material respect as of the date it was or will be dated or (except as otherwise disclosed to the Administrative Agent 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. (n) OFFICES. 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 27 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 the Administrative Agent in accordance with Section 7.1(f), in jurisdictions where all action required by Section 8.5 has been taken and completed). (o) LOCKBOXES AND COLLECTION ACCOUNTS. (i) One of the Loan Parties or the applicable Originator has instructed all Obligors of all Receivables to pay all Collections thereon either (A) by mail addressed to a Lockbox or (B) by wire transfer or other electronic funds transfer directly to a Collection Account in the name of the applicable Originator, as sub-servicer, or in the name of the Borrower. Items received in the Lockboxes are deposited for collection each Business Day into a Collection Account in the name of the applicable Originator or the Borrower, and all collected and available funds from time to time in each Collection Account in the name of any Originator are swept each day to a Collection Account in the name of the Borrower. Each of the Lockboxes and Collections Accounts is in full force and effect and, except for the Collection Account at China Trust Bank, 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, dominion and control over any Collection Account or any Lockbox, or the right to take dominion and control of any of the foregoing at a future time or upon the occurrence of a future event. (iii) Except as otherwise provided in Section 7.3(d), each Collection Account Agreement, and the name and address of each Collection Bank (together with the account numbers of all Collection Accounts maintained with it and the address of each Lockbox maintained with it) are set forth on Schedule 6.1(o). (p) ELIGIBLE RECEIVABLES. Each Receivable included as an Eligible Receivable in the Net Pool Balance in connection with any computation or recomputation of the Borrowing Base is an Eligible Receivable on such date. (q) ERISA. No ERISA Event has occurred or is reasonably expected to occur which could have a Material Adverse Effect. The present value of all accumulated benefit obligations of all underfunded Pension Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed by more than $20.0 million the fair market value of the assets of all such underfunded Pension Plans. Each ERISA Entity is in compliance in all material respects with the presently applicable provisions of ERISA and the Code with respect to each Employee Benefit Plan. Using actuarial assumptions and computation methods consistent with subpart 1 of subtitle E of Title IV of ERISA, the aggregate liabilities of any of each ERISA Entity to all Multiemployer Plans in the event of a complete withdrawal therefrom, as of the close of the most recent fiscal year of each such Multiemployer Plan, would not result in a Material Adverse Effect. All Foreign Plans are in substantial compliance with all 28 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 used any legal names, trade names or assumed names other than the name in which it has executed this Agreement. (s) CREDIT AND COLLECTION POLICY. With respect to the Receivables originated by each of the Originators, each of the applicable Originator, the Borrower and the Servicer has complied in all material respects with the applicable Credit and Collection Policy, and no change has been made to such Credit and Collection Policy since the date of this Agreement which would be reasonably likely to materially and adversely affect the collectibility of the Receivables or decrease the credit quality of any newly created Receivables except for such changes as to which the Administrative Agent have received the notice required under Section 7.2(j) and has given its prior written consent thereto (which consent shall not be unreasonably withheld or delayed). (t) PAYMENTS TO APPLICABLE ORIGINATOR. With respect to each Receivable sold or contributed to the Borrower by any Originator under the Sale Agreement, the Borrower has given reasonably equivalent value to such Originator in consideration for such Receivable and the Related Assets with respect thereto and no such transfer is or may be voidable under any section of the Bankruptcy Reform Act of 1978 (11 U.S.C. Sections101 et seq.), as amended. (u) INVESTMENT COMPANY ACT; PUBLIC UTILITY HOLDING COMPANY ACT; OTHER RESTRICTIONS. No Loan Party is an "investment company", or a company "controlled" by an "investment company", within the meaning of the United States Investment Company Act of 1940, as amended. No Loan Party is a "holding company", or an "affiliate" of a "holding company" or a "subsidiary company" of a "holding company", within the meaning of the United States Public Utility Holding Company Act of 1935, as amended. No Loan Party is subject to regulation under any law or regulation which limits its ability to incur Indebtedness, other than Regulation X of the Board of Governors of the Federal Reserve System. (v) BORROWING BASE; SOLVENCY. The Borrowing Base is at all times at least equal to the aggregate outstanding principal balance of the Advances. As of each Borrowing Date, after giving effect to any Loans to be borrowed on such date, the Borrower is and will be Solvent.

Each of the Borrower and the Servicer shall post all Demand Advances to its respective books in accordance with GAAP on or before each Settlement Date.

The Borrower will cause each of the Collection Accounts that is currently in the name of an Originator to be transferred to it and into its own name within a reasonable period of time after the initial Advance hereunder. (ii) If, notwithstanding the foregoing clause (i) above, any Collections are paid directly to any Loan Party, such Loan Party shall deposit the same (with any necessary indorsements) to a Collection Account within one (1) Business Day after receipt thereof. (iii) Upon demand of the Administrative Agent, the Borrower or the Servicer shall establish a segregated account at Wachovia Bank, N.A. which is subject to a perfected security interest in favor of the Administrative Agent, for the benefit of the Secured Parties (the "COLLATERAL ACCOUNT"), into which all deposits from time to time in the Collection Accounts, and all other Collections, are concentrated pending application in accordance with the terms of this Agreement to the Obligations. 31 (j) FURTHER ASSURANCES.

Section 7.4 SEPARATE EXISTENCE OF THE BORROWER. Each Loan Party hereby acknowledges that Lenders and the Administrative Agent 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 the Administrative Agent 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.

The Borrower will not engage any agents other than its attorneys, auditors and other professionals and a servicer and any other agent contemplated by the Transaction Documents for the Collateral, which servicer will be fully compensated for its services by payment of the Servicer's Fee, and certain organizational expenses in connection with the formation of the Borrower; 36 (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. The Borrower will not incur any material indirect or overhead expenses for items shared with Quest Diagnostics (or any other Affiliate thereof) which are not reflected in the Servicer's Fee. 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 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; (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 the published financial statements of each of the Originators will clearly show that, for accounting purposes, the Receivables 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 37 capacity as the Servicer hereunder or under the Sale Agreement) has independent access, provided that prior to demand by the Administrative Agent 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 the Administrative Agent gives 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 the Administrative Agent 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 the Administrative Agent (or the designee of the 38 Administrative Agent) 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 Administrative Agent (or the Administrative Agent's 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 Administrative Agent as described above, notwithstanding the commencement or continuation of any proceeding to resolve the aforementioned dispute, if the Administrative Agent 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 Administrative Agent at the request of Quest Diagnostics or the Borrower subject to satisfaction of the Rating Agency Condition) is acting as the Servicer, it may subcontract with any other Originator or other direct or indirect Subsidiary of Quest Diagnostics, for servicing, administering or collecting all or any portion of the Receivables, PROVIDED, HOWEVER, that no such subcontract shall relieve Quest Diagnostics (or such approved affiliated substitute Servicer, if such approval is not conditioned upon Quest Diagnostics' issuance of a performance guaranty with respect to such affiliated substitute Servicer) of its primary liability for performance of its duties as Servicer pursuant to the terms hereof and any such sub-servicing arrangement may be terminated at the request of the Administrative Agent at any time after a Successor Notice has been given. In addition to the foregoing, with the prior written consent of the Administrative Agent (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 the Administrative Agent at any time that the Administrative Agent reasonably determines 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. 39 Section 8.2 DUTIES OF SERVICER. (a) APPOINTMENT; DUTIES IN GENERAL. Each of the Borrower, the Lenders and the Administrative Agent 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 the Administrative Agent) to segregate the funds constituting Collections prior to the remittance thereof in accordance with Article III. If instructed by the Administrative Agent, 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 Administrative Agent or the Lenders under Section 3.4). (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 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.

(b) NOTICE TO COLLECTION BANKS. At any time, the Administrative Agent is hereby authorized to give notice to the Collection Banks, as provided in the Collection Account Agreements, of the transfer to the Administrative Agent of dominion and control over the Lockboxes and the Collection Accounts. The Borrower and the Servicer hereby transfer to the Administrative Agent, effective when the Administrative Agent shall give notice to the Collection Banks as provided in the Collection Account Agreements, the exclusive dominion and control over the Lockboxes and the Collection Accounts, and shall take any further action that the Administrative Agent may reasonably request to effect such transfer.

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 Non-Assignable Contract, and each Loan Party shall remain responsible for performing all of its obligations (if any) under all other Contracts, to the same extent as if the ownership interest or security interests in such Contracts had not been granted under the Transactions Documents, and the exercise by the Administrative Agent or its designee of its rights hereunder shall not relieve any such Person from such obligations. (b) LIMITATION OF LIABILITY. The Secured Parties shall not have any obligation or liability with respect to any Receivables, Invoices or Contracts, nor shall any of them be obligated to perform any of the obligations of any Loan Party or any Originator thereunder.

Each Loan Party agrees that from time to time, at its expense, it will promptly execute and deliver all further instruments and documents, and take all further action that the Administrative Agent or its designee may reasonably request in order to perfect, protect or more fully evidence the Administrative Agent's security interest, on behalf of the Secured Parties, in the Collateral, or to enable the Administrative Agent or its designee to exercise or enforce any of the Secured Parties' respective rights hereunder or under any Transaction Document in respect thereof.

If the Administrative Agent (other than Wachovia Bank, N.A.) shall voluntarily resign or be removed as Administrative Agent under this Agreement, then the Majority Lenders during such five-day period shall appoint, with the consent of the Borrower from among the remaining Liquidity Banks, a successor administrative agent, whereupon such successor administrative agent shall succeed to the rights, powers and duties of the Administrative Agent and the term "Administrative Agent" shall mean such successor agent, effective upon its appointment, and the former Administrative Agent's rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement. Upon resignation or replacement of any Administrative Agent in accordance with this Section 11.9, the retiring Administrative Agent shall execute such UCC-3 assignments and amendments, and assignments and amendments of the Transaction Documents, as may be necessary to give effect to its replacement by a successor Administrative Agent. After any retiring Administrative Agent's resignation hereunder as Administrative Agent, the provisions of this Article XI and Article XIII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. Section 11.10 CONFLICT WAIVERS. Wachovia acts, or may in the future act, (i) as administrative agent for Blue Ridge, (ii) as issuing and paying agent for Blue Ridge's Commercial Paper Notes, (iii) to provide credit or liquidity enhancement for the timely payment for Blue Ridge's Commercial Paper Notes and (iv) to provide other services from time to time for Blue Ridge (collectively, the "WACHOVIA ROLES"). Without limiting the generality of Sections 11.1 and 11.8, each of the Administrative Agent and the Lenders hereby acknowledges and consents to any and all Wachovia Roles and agrees that in connection with any Wachovia Role, Wachovia may take, or refrain from taking, any action which it, in its discretion, deems appropriate, including, without limitation, in its role as administrative agent for Blue Ridge, the giving of notice to the Liquidity Banks of a mandatory purchase pursuant to the Liquidity Agreement, and hereby acknowledges that neither Wachovia nor any of its Affiliates has any fiduciary duties hereunder to any Lender (other than Blue Ridge) arising out of any Wachovia 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 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. 50 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 the Administrative Agent 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 Administrative Agent's 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) Blue Ridge may, at any time, assign all or any portion of any Loan, or sell participations therein, to the Liquidity Banks (or to the Administrative Agent for the ratable benefit of the 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 any Liquidity Bank becomes a Downgraded Liquidity Bank, such Downgraded Liquidity Bank shall give prompt written notice of its Downgrading Event to the Administrative Agent and to the Borrower. Within 5 Business Days after the Borrower's receipt of such notice, the Borrower may propose an Eligible Assignee who is willing to accept an assignment of, and to assume, such Downgraded Liquidity Bank's rights and obligations under this Agreement and under the Liquidity Agreement. In the event that the Borrower fails to propose such an Eligible Assignee within such 5 Business Day period, or such Eligible Assignee does not execute and deliver assignment and assumption documents reasonably acceptable to such Downgraded Liquidity Bank and the Administrative Agent and pays the Downgraded Liquidity Bank's Obligations in full, in each case, not later than 5:00 p.m. (New York City time) on the 10th Business Day following the Borrower's receipt of notice of such Downgrading Event, the Administrative Agent may identify an Eligible Assignee without the Borrower's consent, and the Downgraded Liquidity Bank shall promptly assign its rights and obligations to the Eligible Assignee designated by the Administrative Agent against payment in full of its Obligations; (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) the Administrative Agent, which consents shall not be unreasonably withheld or delayed.

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 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. 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 Administrative 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 Administrative 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 the extent assigned. 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, 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 or (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; 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 52 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, 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 other than the Non-Assignable Contracts, or a first-priority perfected security interest in favor of the Borrower and the Administrative Agent as its assignee, in the rights to receive payments under each of the Non-Assignable Contracts; 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) the failure to file, or any delay in filing, financing statements or other similar instruments or documents under the UCC of any applicable jurisdiction or other applicable laws with respect to any Collateral; (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; 53 (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 Tax (but not including Taxes upon or measured by net income or net profits or franchise Taxes in lieu of net income or net profits Taxes), 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 security interest in the Receivables 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 Receivable; (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); or (P) any loss incurred by any of the Secured Parties as a result of the inclusion in the Borrowing Base of Receivables owing from any single Obligor and its Affiliated Obligors which causes the aggregate Unpaid Net Balance of all such Receivables to exceed the applicable Obligor Concentration Limit. (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 54 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 55 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. ARTICLE XIV MISCELLANEOUS Section 14.1 AMENDMENTS, ETC. 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 Administrative Agent, 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 the Administrative Agent enters into such an amendment or granting such a waiver or consent that is deemed to be material by S&P and/or Moody's, the Rating Agency Condition must be satisfied, (b) without the prior written consent of all Liquidity Banks, the Administrative Agent will not amend, modify or waive any provision of this Agreement which would (i) reduce the amount of any principal or interest that is payable on account of Blue Ridge's Loans or delay any scheduled date for payment thereof; (ii) decrease the Required Reserve, decrease the spread included in any Interest Rate or change the Servicer's Fee; (iii) modify this Section 14.1; (iv) modify the definition of "MAJORITY LENDERS", or (v) modify any yield protection or indemnity provision which expressly inures to the benefit of assignees or participants of Blue Ridge, and (c) without the prior written consent of the Majority Lenders, waive, amend or consent to a departure from any Event of Default.

The remedies herein provided are cumulative and not exclusive of any remedies provided by law. 56 Without limiting the foregoing, each of the Administrative Agent and the Lenders is hereby authorized by the Borrower at any time and from time to time, to the fullest extent permitted by law, to set off and apply to payment of any Obligations that are then due and owing any and all deposits (general or special, time or demand provisional or final) at any time held and other indebtedness at any time owing by such Person to or for the credit or the account of the Borrower.
