ARTICLE I.
AMOUNTS AND TERMS OF THE PURCHASES

Section 1.1 [Reserved].

Section 1.2 Purchases of Private Receivables and Participation Interests.

(a) Effective on the Applicable Closing Date for each Seller that has not already sold or contributed Private Receivables and Related Assets or Participation Interests and Related Assets under the Previous Agreements (including by operation of Section 1.1 of the Existing Agreement), in consideration for the Purchase Price and upon the terms and subject to the conditions set forth herein, each such Seller does hereby sell, assign, transfer, set-over and otherwise convey to the Buyer, without recourse (except to the extent expressly provided herein), and the Buyer does hereby purchase from

such Seller, all of such Seller’s right, title and interest in and to such Seller’s Initial Private Receivables and all Related Assets with respect thereto and such Seller’s Initial Participation Interests and all Related Assets with respect thereto.

(b) Effective on each Business Day after each Seller’s Applicable Closing Date and prior to the Sale Termination Date, in consideration for the Purchase Price and upon the terms and subject to the conditions set forth herein, such Seller does hereby sell, assign, transfer, set-over and otherwise convey to the Buyer, without recourse (except to the extent expressly provided herein), and the Buyer does hereby purchase from such Seller, all of such Seller’s right, title and interest in and to such Seller’s Additional Private Receivables and all Related Assets with respect thereto and such Seller’s Additional Participation Interests and all Related Assets with respect thereto.

(c) It is the intention of the parties hereto that each conveyance of Private Receivables and Participation Interests made under this Agreement shall constitute an outright “sale of accounts” (as such terms are used in Article 9 of the UCC) or other absolute transfer, which is absolute and irrevocable and shall provide the Buyer with the full benefits of ownership of the Private Receivables, Participation Interests and the associated Related Assets. Except for the Purchase Price Credits owed pursuant to Section 1.4, each conveyance of Private Receivables and Participation Interests hereunder is made without recourse to the applicable Seller; provided, however, that (i) each Seller shall be liable to the Buyer for all representations, warranties, covenants and indemnities made by such Seller pursuant to the terms of the Transaction Documents to which such Seller is a party, and (ii) such conveyance does not constitute and is not intended to result in an assumption by the Buyer or any assignee thereof of any obligation of such Seller or any other Person arising in connection with the Participation Interests, the Private Receivables, the related Contracts, and/or other Related Assets or any other obligations of such Seller. In view of the intention of the parties hereto that the conveyances of Private Receivables and Participation Interests made hereunder shall constitute outright sales of such Private Receivables and Participation Interests rather than loans secured thereby, each Seller agrees that it will, on or prior to its Applicable Closing Date, ▇▇▇▇ its master data processing records relating to its Receivables with the following legend (or the substantive equivalent thereof):

“THE RECEIVABLES DESCRIBED HEREIN, TOGETHER WITH CERTAIN RELATED ASSETS, ARE EITHER THE PROPERTY OF Quest Diagnostics Receivables Inc. OR SUBJECT TO RIGHTS OF QUEST DIAGNOSTICS RECEIVABLES INC.”

Upon the request of the Buyer or the Administrative Agent, each Seller will file such financing or continuation statements, or amendments thereto or assignments thereof, and such other instruments or notices, as may be necessary or appropriate to perfect and maintain the perfection of the Buyer’s ownership interest in the Private Receivables, the Participation Interests and the respective Related Assets or as the Buyer or the Administrative Agent may reasonably request.

(d) Nothing herein shall be deemed to preclude Quest Diagnostics from contributing to the Buyer’s capital, in lieu of selling, Private Receivables and Participation Interests in Specified Government Receivables, in each case originated by Quest Diagnostics together with the Related Assets associated therewith, and any such contribution is made with the intention that each such contribution, if any, will be made with the same intentions as are set forth in Section 1.2(c) above. No Purchase Price shall be payable in respect of any contributed Private Receivable, Participation Interest or its respective associated Related Assets.

(e) Following each sale or contribution of a Participation Interest in a Specified Government Receivable, each Seller hereby agrees to hold such Government Receivable and any Related Assets and proceeds with respect thereto for the benefit of the Buyer; provided that no Seller shall take any action in contravention of any law, rule or regulation applicable to such Specified Government Receivable. It is understood and agreed that sales and contributions of Participation Interests in Specified Government Receivables shall not include any right to collect the proceeds of any Specified Government Receivable directly from the applicable Governmental Entity, except insofar as a court of competent jurisdiction shall order such Governmental Entity to make such payments directly to the Buyer or its assigns.

Section 1.3 Payment for the Purchases.

(a) The Purchase Price for each purchase of Initial Private Receivables and Related Assets from any Seller (other than Quest Diagnostics) and each purchase of Initial Participation Interests and Related Assets from any Seller (other than Quest Diagnostics) either has been paid pursuant to the Existing Agreements or shall be payable in full pursuant to this Agreement by the Buyer to such Seller on such Seller’s Applicable Closing Date in one or both of the following manners:

(i) by delivery of immediately available funds, to the extent of the Buyer’s Available Funds, and/or by arranging for the issuance of one or more Letters of Credit; and

(ii) solely to the extent such Available Funds and the face amount of the Letters of Credit arranged are insufficient to pay the full amount of Purchase Price then due and owing, by delivery of a Subordinated Note made by the Buyer to the applicable Seller (and making a notation of a Subordinated Loan thereunder), so long as the aggregate principal amount of Subordinated Loans outstanding at any one time under such Subordinated Notes does not exceed the lesser of (A) the remaining unpaid portion of such Purchase Price, and (B) the maximum Subordinated Loan that could be borrowed without rendering the Buyer’s net worth less than the amount required by Section 7.3(g) of the Credit and Security Agreement.

The Purchase Price for each purchase of Additional Private Receivables and Related Assets and each purchase of Additional Participation Interests and Related Assets shall be due and owing in full by the Buyer to the applicable Seller on the date of such purchase (except that the Buyer may, with respect to any such purchase, offset against such Purchase Price any amounts owed by such Seller to the Buyer hereunder and which have become due but remain unpaid) and shall be paid to such Seller in the manner provided in the following paragraphs (b), (c) and (d).

(b) With respect to any purchase of Additional Private Receivables and Related Assets from any Seller and any purchase of Additional Participation Interests and Related Assets from any Seller, the Buyer shall pay the Purchase Price therefor on the next subsequent Settlement Date in accordance with Section 1.3(d) and in one or more of the following manners:

(i) by delivery of immediately available funds, to the extent of the Buyer’s Available Funds, and/or by arranging for the issuance of one or more Letters of Credit; and

(ii) solely to the extent such Available Funds and the face amount of the Letters of Credit arranged are insufficient to pay the full amount of Purchase Price then due and

owing, by delivery of a Subordinated Note made by the Buyer to the applicable Seller (or by increasing the aggregate outstanding principal amount outstanding thereunder), so long as the aggregate principal amount of Subordinated Loans outstanding at any one time under such Subordinated Note does not exceed the lesser of (A) the remaining unpaid portion of such Purchase Price, and (B) the maximum Subordinated Loan that could be borrowed without rendering the Buyer’s net worth less than the amount required by Section 7.3(g) of the Credit and Security Agreement.

Subject to the limitations set forth in Section 1.3(a)(ii) and Section 1.3(b)(ii), each of the Sellers irrevocably agrees to advance each Subordinated Loan requested by the Buyer on or prior to such Seller’s Sale Termination Date. The Subordinated Loans owing to each Seller shall be evidenced by, and shall be payable in accordance with the terms and provisions, of its Subordinated Note and shall be payable solely from Available Funds. Each Seller is hereby authorized by the Buyer to endorse on the schedule attached to its Subordinated Note an appropriate notation evidencing the date and amount of each Subordinated Loan thereunder, as well as the date of each payment with respect thereto, provided that the failure to make such notation shall not affect any obligation of the Buyer thereunder.

(c) On each Monthly Reporting Date after its Applicable Closing Date, each Seller shall (or shall require the Servicer to) deliver to the Buyer and the Administrative Agent a report in substantially the form of Exhibit A hereto (each such report being herein called a “Purchase Report”) with respect to the Private Receivables and Participation Interests sold by such Seller to the Buyer during the Settlement Period then most recently ended. Each such Purchase Report shall list the applicable Seller separately and shall specify, as applicable: (i) the Initial Private Receivables, Additional Private Receivables, Initial Participation Interests and/or Additional Participation Interests sold by such Seller during the Settlement Period then most recently ended, (ii) the amount of the Private Receivables described in the foregoing clause (i) that were Eligible Receivables on the date they were acquired by the Buyer, and (iii) the amount of the Participation Interests described in the foregoing clause (i) that were Eligible Participation Interests on the date they were acquired by the Buyer.

(d) Although the Purchase Price for each purchase of Additional Private Receivables and Related Assets and purchase of Additional Participation Interests and Related Assets shall be due and payable in full by the Buyer to the applicable Seller on the date of such purchase, settlement of the Purchase Price between the Buyer and such Seller shall be effected on Settlement Dates with respect to all purchases within the same Settlement Period and based on the information contained in the Purchase Report delivered for such Settlement Period pursuant to Section 1.3(c). Although cash settlements shall be effected on Settlement Dates, increases or decreases in the Subordinated Loans shall be deemed to have occurred and shall be effective as of the last Business Day of the Settlement Period to which such settlement relates.

Section 1.4 Purchase Price Credit Adjustments. If as of the last day of any Settlement Period:

(a) the outstanding aggregate balance of the Net Private Receivables originated by any Seller and the Net Participation Interests as reflected in the preceding Purchase 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 Seller or any Affiliate thereof (regardless of whether the same is treated by such Seller 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 Seller or any Affiliate thereof to pay to the related Obligor any rebate or refund, or

(iv) as a result of any Unpaid Net Balance of any Private Receivable or Participation Interest on the date of its sale or contribution proving to have been less on such date than the amount reflected on the applicable Purchase Report, or

(b) any of the representations or warranties of the applicable Seller set forth in Section 2.1(d), (k) or (m) was not true when made with respect to any Private Receivable originated by it or any Participation Interest in any Specified Government Receivable originated by it, or any of the representations or warranties of the applicable Seller set forth in Section 2.1(m) is no longer true with respect to any Private Receivable or any Participation Interest in any Specified Government Receivable originated by it,

then, in such event, the Buyer shall be entitled to a credit (each, a “Purchase Price Credit”) against the Purchase Price otherwise payable hereunder 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). If such Purchase Price Credit exceeds the original Unpaid Net Balance of the Private Receivables and Participation Interests to be sold by the applicable Seller on the date of a purchase, then the applicable Seller shall pay the remaining amount of such Purchase Price Credit in cash not later than the next Settlement Date; provided that if such Seller’s Sale Termination Date has not occurred, such Seller shall be allowed to deduct the remaining amount of such Purchase Price Credit from any Indebtedness owed to it under its Subordinated Note.

Section 1.5 Payments and Computations, Etc. All amounts to be paid or deposited by the Buyer hereunder shall be paid or deposited in accordance with the terms hereof on the day when due in immediately available funds to the account of the applicable Seller designated from time to time by such Seller or as otherwise directed by such Seller. In the event that any payment owed by any Person hereunder becomes due on a day that is not a Business Day, then such payment shall be made on the next succeeding Business Day. If any Person fails to pay any amount hereunder when due, such Person agrees to pay, on demand, interest on the past due amount at the Default Rate until paid in full; provided, however, that such interest shall not at any time exceed the maximum rate permitted by applicable law. All computations of interest payable hereunder shall be made on the basis of a year of 360 days for the actual number of days (including the first but excluding the last day) elapsed.

Section 1.6 Transfer of Records.

(a) In connection with the purchases of Private Receivables and Participation Interests hereunder, each Seller hereby sells, transfers, assigns and otherwise conveys to the Buyer all of such

Seller’s right and title to and interest in the Records relating to all Private Receivables and the Specified Government Receivables the subject of Participation Interests sold hereunder, without the need for any further documentation in connection with any purchase. In connection with such transfer, each Seller hereby grants to each of the Buyer, the Administrative Agent and the Servicer an irrevocable, non-exclusive license to use, without royalty or payment of any kind, all software used by such Seller to account for its Receivables, to the extent necessary to administer such Receivables following replacement of Quest Diagnostics (or any of its Affiliates) as the Servicer, whether such software is owned by such Seller or is owned by others and used by such Seller under license agreements with respect thereto, provided that should the consent of any licensor of such Seller to such grant of the license described herein be required, such Seller hereby agrees that upon the request of the Buyer, the Servicer or the Administrative Agent, such Seller will use its reasonable efforts to obtain the consent of such third-party licensor. The license granted hereby shall be irrevocable, and shall terminate on the date this Agreement terminates in accordance with its terms.

(b) Each Seller (i) shall take such action requested by the Buyer and/or the Administrative Agent, from time to time hereafter, that may be necessary or reasonably appropriate to ensure that the Buyer has an enforceable ownership interest in the Records relating to the Private Receivables and the Specified Government Receivables the subject of Participation Interests purchased from such Seller hereunder, and (ii) shall use its reasonable efforts to ensure that the Buyer and the Servicer each has an enforceable right (whether by license or sublicense or otherwise) to use all of the computer software used to account for such Receivables and/or to recreate such Records.

Section 1.7 Characterization; Granting Clause.

(a) If, notwithstanding the intention of the parties expressed in Section 1.2(c), any sale by any of the Sellers to the Buyer of Receivables hereunder shall be characterized as a secured loan and not a sale, then this Agreement shall be deemed to constitute a security agreement under the UCC and other applicable law. For this purpose and without being in derogation of the parties’ intention that each sale of Private Receivables and Participation Interests hereunder shall constitute a true sale thereof, each of the Sellers hereby grants to the Buyer a duly perfected security interest in all of such Seller’s right, title and interest in, to and under all of such Seller’s Private Receivables and Participation Interests now existing and hereafter arising, and in all Related Assets with respect thereto, which security interest shall be prior to all other Liens thereto. After the occurrence of a Seller’s Sale Termination Event, the Buyer and its assigns shall have as against the applicable Seller, in addition to the rights and remedies which they may have under this Agreement, all other rights and remedies provided to a secured creditor after default under the UCC and other applicable law, which rights and remedies shall be cumulative.

(b) Each Seller hereby covenants and agrees to do all things necessary under each of its Contracts to facilitate collection of the Receivables arising thereunder by the Buyer and its assigns.

Section 1.8 Letters of Credit. Each of the Originators hereby appoints Quest Diagnostics as its payment agent (in such capacity, together with its successors in such capacity, the “Payment Agent”), and Quest Diagnostics hereby accepts such appointment and agrees to act as the Payment Agent in accordance with the terms of this Section. In the event that a Letter of Credit expires or is terminated and has not been drawn, the Buyer hereby agrees to pay to the Payment Agent, for the account of the Originator(s) specified by the Payment Agent, by delivery of immediately available funds to the extent of its Available Funds and/or by making a notation of a Subordinated Loan or Subordinated Loans to such Originator(s) as the Payment Agent may specify, in an aggregate amount equal to the face

amount of the expired or terminated Letter of Credit. The Payment Agent shall have no liability to the Originators except for losses determined by a court of competent jurisdiction to have resulted from bad faith, gross negligence or willful misconduct on the part of the Payment Agent.

ARTICLE II.
REPRESENTATIONS AND WARRANTIES

Section 2.1 Representations of the Sellers. In order to induce the Buyer to enter into this Agreement and to make purchases and accept the contributions hereunder, each Seller hereby makes the following representations and warranties, as to itself, as of the date of each sale or contribution by it hereunder:

(a) Ownership of such Seller. Quest Diagnostics owns, directly or indirectly, all or substantially all of the issued and outstanding Equity Interests of each of the other Sellers, and all of such Equity Interests are fully paid and non-assessable.

Such Seller holds all governmental permits, licenses, authorizations, consents and approvals necessary for such Seller to own, lease, and operate its Properties and to operate its businesses as now being conducted (collectively, the “Permits”), except for Permits the failure of which to obtain would not have a Seller Material Adverse Effect.

(d) Title to Receivables; Valid Security Interest. Each such Private Receivable originated by such Seller and each such Participation Interest has been transferred to the Buyer free and clear of any Lien except as created hereby or by the other Transaction Documents. Without limiting the

This Agreement creates a valid security interest in each such Private Receivable and its Related Assets and such Participation Interest and Related Assets in favor of the Buyer, and, upon filing of the financing statements described in the preceding sentence, together with UCC termination statements delivered hereunder, such security interest will be a first priority perfected security interest.

(e) Absence of Change of Control. No Change of Control has occurred.

(ii) Such Seller is not in default under any material contract or agreement to which it is a party or by which it is bound, nor, to such Seller’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 Seller Material Adverse Effect.

(g) No Proceedings. Except as described in Quest Diagnostics’ Form 10-K for the fiscal year ended December 31, 2014 and all filings made with the SEC under the Exchange Act by such Seller prior to the date of this Agreement, copies of which have been provided to the Buyer and the Administrative Agent or made available on ▇▇▇▇▇:

(i) There is no Proceeding (other than any qui tam Proceeding, to which this Section is limited to the best of such Seller’s knowledge) pending against, or, to the knowledge of such Seller, threatened in writing against or affecting, such Seller or any of its Properties before any Governmental Authority that, if determined or resolved adversely to such Seller, could reasonably be expected to have a Seller Material Adverse Effect.

(b) Performance Under Contract. Each Seller shall remain responsible for performing its obligations hereunder and under the Contracts applicable to such Seller, and the exercise by the Buyer or its designee of its rights hereunder shall not relieve any Seller from such obligations.

(c) Power of Attorney. Each Seller hereby grants to the Servicer (if other than such Seller) an irrevocable power of attorney, with full power of substitution, coupled with an interest, to take in the name of such Seller all steps necessary or advisable to endorse, negotiate or otherwise realize on any writing or other right of any kind held or transmitted by such Seller or transmitted or received by the Buyer (whether or not from such Seller) in connection with any Receivables generated by such Seller.

Section 6.3 Further Action Evidencing Purchases. Each Seller agrees that from time to time, at its expense, it will promptly execute (if required) and deliver all further instruments and documents, and take all further action that the Buyer may reasonably request in order to perfect, protect or more fully evidence the Buyer’s ownership of the Private Receivables generated by such Seller (and the Related Assets) and the Participation Interests (and the Related Assets) purchased by the Buyer hereunder, or to enable the Buyer to exercise or enforce any of its rights hereunder or under any other Transaction Document. Without limiting the generality of the foregoing, upon the request of the Buyer, each Seller will:

(d) file such financing or continuation statements, or amendments thereto or assignments thereof, and such other instruments or notices, as may be necessary or appropriate; and

(e) ▇▇▇▇ the summary master control data processing records with the legend set forth in Section 1.1(c).

Each Seller hereby authorizes the Buyer or its designee to file one or more financing or continuation statements, and amendments thereto and assignment thereof, relative to all or any of the Private Receivables (and the Related Assets) and the Participation Interests (and the Related Assets) now existing or hereafter sold by such Seller. If such Seller fails to perform any of its agreements or obligations under this Agreement, the Buyer or its designee may (but shall not be required to) itself perform, or cause performance of, such agreement or obligation, and the expenses of the Buyer or its designee incurred in connection therewith shall be payable by such Seller.

Section 6.4 Application of Collections. Except as otherwise specified by such Obligor or required by the underlying Contract or law: any payment by an Obligor in respect of any indebtedness owed by it to such Seller or to the Buyer shall be applied first, as a Collection of any Receivable or Receivables then outstanding of such Obligor in the order of the age of such Receivables, starting with the oldest of such Receivables (unless another reasonable basis for allocation of such payments to the Receivables of such Obligor exists), and second, to any other indebtedness of such Obligor.

ARTICLE VII.
INDEMNIFICATION

Section 7.1 Indemnities by the Sellers. Without limiting any other rights which any such Person may have hereunder or under applicable law, each of the Sellers hereby agrees to indemnify the Buyer, its assigns, and each of their respective Affiliates, and all successors, transferees, participants and assigns and all officers, directors, shareholders, controlling persons, employees and agents (each, a “Seller Indemnified Party”), forthwith on demand, from and against any and all damages, losses, claims, liabilities and related costs and expenses, including attorneys’ fees and disbursements (all of the foregoing being collectively referred to as “Seller Indemnified Amounts”) awarded against or incurred by any of them arising out of or relating to this Agreement, any of the other Transaction Documents to which such Seller is a party, the Private Receivables and Related Assets and/or the Participation Interests and Related Assets, excluding, however, (i) Seller 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 Seller Indemnified Party, (ii) taxes imposed by the jurisdiction in which such Seller Indemnified Party’s principal executive office is located, on or measured by the overall net income of such Seller Indemnified Party; and (iii) recourse (except as otherwise specifically provided in this Agreement) for Seller 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. Without limiting the foregoing, each of the Sellers shall indemnify each Seller Indemnified Party for Seller Indemnified Amounts arising out of or relating to:

(D) the failure to vest and maintain vested in the Buyer, a valid and perfected ownership interest in the Private Receivables, Participation Interest and the associated Related Assets sold or contributed by such Seller hereunder, free and clear of any other Lien, other than a Lien arising solely as a result of the Buyer, 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 Private Receivables, Participation Interests or Related Assets sold or contributed by such Seller hereunder;

(F) any dispute, claim, offset or defense (other than discharge in bankruptcy) of the Obligor to the payment of any Receivable originated by such Seller (including, without limitation, a defense based on such Receivable or the related Contract 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 1.4;

(H) any failure of such Seller 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 relating to a breach by such Seller of any related Contract or Invoice with respect to any Receivable;

(J) any sales or use tax payable in connection with the transactions giving rise to any Receivable originated by such Seller, and any documentary stamp taxes or recording taxes associated with the perfection of the Buyer’s ownership in the Private Receivables, Participation Interests and respective Related Assets;

(K) the commingling by such Seller 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 to which such Seller is a party, the transactions contemplated hereby or thereby, the use of the proceeds of any sale, the Buyer’s ownership interest in the Receivables and Related Assets originated by such Seller or any other investigation, litigation or proceeding relating to such Seller or the Receivables and Related Assets originated by it in which any Seller Indemnified Party becomes involved as a result of any of the transactions contemplated hereby or thereby;

(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 or Invoice or any Receivable originated by such Seller;

(N) any inability to litigate any claim against any Obligor in respect of any Receivable originated by such Seller 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; or

(O) the occurrence of any Event of Bankruptcy with respect to such Seller.

In addition to Quest Diagnostics’ obligations under the foregoing indemnity with respect to itself as a Seller and the Receivables originated by it, Quest Diagnostics hereby agrees to be jointly and severally liable with each other Seller for such other Seller’s indemnity obligations set forth above.

Section 7.2 Contribution. If for any reason the indemnification provided above in Section 7.1 (and subject to the exceptions set forth therein) is unavailable to a Seller Indemnified Party or is insufficient to hold a Seller Indemnified Party harmless, then the applicable Seller(s) shall contribute to the amount paid or payable by such Seller 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 Seller Indemnified Party on the one hand and the applicable Seller(s) on the other hand but also the relative fault of such Seller Indemnified Party as well as any other relevant equitable considerations.
