The Seller (i) desires to sell, transfer and assign an undivided percentage ownership interest in a pool of receivables, and the Purchasers desire to acquire such undivided percentage ownership interest, as such percentage interest shall be adjusted from time to time based upon, in part, reinvestment payments that are made by such Purchasers, and (ii) may, subject to the terms and conditions hereof, request that the LC Bank issue or cause the issuance of one or more Letters of Credit.

In consideration of the mutual agreements, provisions and covenants contained herein, the sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

AMOUNTS AND TERMS OF THE PURCHASES

Section 1.1 Purchase Facility .

(a) On the terms and subject to the conditions hereof, the Seller may, from time to time before the Termination Date, (i) request that (x) the Conduit Purchasers ratably (based on the aggregate Commitments of the Related Committed Purchasers in their respective Purchaser Groups) make purchases (and deemed purchases) of and reinvestments in, or (y) only if a Conduit Purchaser denies such request or is unable to fund (and provides notice of such denial or inability to the Seller, the Administrator and its Purchaser Agent), the Related Committed Purchasers ratably (based on their respective Commitments) make purchases (and deemed purchases) of and reinvestments in, undivided percentage ownership interests with regard to the Purchased Interest from the Seller and (ii) request that the LC Bank issue or cause the issuance of Letters of Credit (each such purchase, deemed purchase, reinvestment or issuance is referred to herein as a “ Purchase ”). Subject to Section 1.4(b) concerning reinvestments, at no time will a Conduit Purchaser have any obligation to make a Purchase. Each Related Committed Purchaser

severally hereby agrees, on the terms and subject to the conditions hereof, to make purchases of and reinvestments in undivided percentage ownership interests with regard to the Purchased Interest from the Seller from time to time from the Closing Date to (but excluding) the Termination Date, based on the applicable Purchaser Group’s Ratable Share of each Purchase requested pursuant to Section 1.2(a) (and, in the case of each Related Committed Purchaser, its Commitment Percentage of its Purchaser Group’s Ratable Share of such Purchase) and, on the terms of and subject to the conditions of this Agreement, the LC Bank hereby agrees to issue Letters of Credit in return for (and each LC Participant hereby severally agrees to make Participation Advances in connection with any draws under such Letters of Credit equal to such LC Participant’s Pro Rata Share of such draws), undivided percentage ownership interests with regard to the Purchased Interest from the Seller from time to time from the Closing Date to (but excluding) the Termination Date. Notwithstanding anything set forth in this Section 1.1(a) or otherwise herein to the contrary, under no circumstances shall any Purchaser make any purchase or reinvestment (including, without limitation, any Purchases deemed to have been requested by Seller pursuant to Section 1.14(a) ) or issue any Letters of Credit hereunder, as applicable, if, after giving effect to such Purchase:

(b) On the date of each purchase requested by the Seller pursuant to Section 1.2(a) , each applicable Conduit Purchaser or Related Committed Purchaser, as the case may be, shall, upon satisfaction of the applicable conditions set forth in Exhibit II , make available to the Seller in same day funds, at the Purchase Account (or such other account as may be designated in writing by the Seller to the Administrator and each Purchaser Agent), an amount equal to the portion of Capital relating to the undivided percentage ownership interest then being purchased by such Purchaser.

(c) Effective on the date of each Purchase pursuant to this Agreement, the Seller hereby sells and assigns to the Administrator for the benefit of the Purchasers (ratably, based on the Aggregate Capital plus the LC Participation Amount outstanding at such time for each such Purchaser’s Capital) an undivided percentage ownership interest in: (i) each Pool Receivable then existing, (ii) all Related Security with respect to such Pool Receivables and (iii) all Collections with respect to, and other proceeds of, such Pool Receivables and Related Security.

(d) To secure all of the Seller’s obligations (monetary or otherwise) under this Agreement and the other Transaction Documents to which it is a party, whether now or hereafter existing or arising, due or to become due, direct or indirect, absolute or contingent (collectively, the “ Obligations ”), the Seller hereby grants to the Administrator (for the benefit of the Administrator, the Purchasers, the Purchaser Agents and their respective permitted assigns) a security interest in all of the Seller’s right, title and interest (including any undivided interest of the Seller) in, to and under all of the following, whether now or hereafter owned, existing or arising: (i) all Pool Receivables, (ii) all Related Security with respect to such Pool Receivables, (iii) all Collections with respect to such Pool Receivables, (iv) the Lock-Box Accounts and all amounts on deposit therein, and all certificates and instruments, if any, from time to time evidencing such Lock-Box Accounts and amounts on deposit therein, (v) all rights (but none of the obligations) of the Seller under the Purchase and Sale Agreement and (vi) all proceeds of, and all amounts received or receivable under any or all of, the foregoing (collectively, the “ Pool Assets ”). The Seller hereby authorizes the Administrator to file financing statements naming the Seller as debtor or seller and describing the collateral covered thereby as “all of the debtor’s personal property or assets” or words to that effect, notwithstanding that such wording may be broader in scope than the collateral described in this Agreement. The Administrator (on behalf of itself, the Purchasers, the Purchaser Agents and their respective permitted assigns) shall have, with respect to the Pool Assets, and in addition to all the other rights and remedies available to the Administrator and the Purchasers, all the rights and remedies of a secured party under any applicable UCC.

(e) Provided that no Termination Event or Unmatured Termination Event exists and is continuing, the Seller may request, in a written notice given to the Administrator and each Purchaser Agent, not less than 30 days and not more than 90 days prior to each anniversary of the Closing Date, that the then-current Scheduled Termination Date be extended to the date that is one year after such then-current Scheduled Termination Date. In the event that the Purchasers in any Purchaser Group are agreeable to such extension, the Administrator shall so notify the Seller and the Servicer in writing (it being understood that the Purchasers may accept or decline such a request in their sole discretion and on such terms as they may elect) and the Seller, the Servicer, the Purchasers, the Purchaser Agents and the Administrator shall enter into such documents as the Purchasers may reasonably deem necessary or appropriate to reflect such extension. In the event the Purchasers in any Purchaser Group decline the request for such extension, such Purchasers (or their Purchaser Agent) shall so notify the Administrator, and the Administrator shall so notify the Seller of such determination; provided , that the failure of the Administrator to affirmatively notify the Seller of any Purchasers’ election regarding such extension request within 30 days following receipt of such request shall be deemed to be a refusal by such Purchasers to grant the requested extension. If the Purchasers in any Purchaser Group do not agree to an extension request, the Seller may cause such Purchasers to assign their interests, rights and obligations under this Agreement and the other Transaction Documents to new Purchasers as provided under Section 5.3(g) . If the Scheduled Termination Date is extended with respect to one or more, but less than all, Purchasers and the Exiting Purchasers are not replaced as described in the foregoing sentence, then the Purchase Limit shall be reduced by an amount equal to the Commitment(s) of the Exiting Purchaser(s).

(f) Each Related Committed Purchaser’s and LC Participant’s obligations hereunder shall be several, such that the failure of any Related Committed Purchaser or LC Participant to make a payment in connection with any purchase hereunder, or drawing under a Letter of Credit hereunder, as the case may be, shall not relieve any other Related Committed Purchaser or LC Participant of its obligations hereunder to make payment for any Funded Purchase or such drawing.

Thereafter, until the Termination Date, the Purchased Interest shall be automatically recomputed (or deemed to be recomputed) on each Business Day other than a Termination Day.

In the event the Seller fails to reimburse the LC Bank for the full amount of any drawing under any Letter of Credit by the applicable time, on the Reimbursement Date (including because the conditions precedent to a Reimbursement Purchase deemed to have been requested by the Seller pursuant to this Section 1.14(a) to reimburse the LC Bank shall not have been satisfied), the LC Bank will promptly notify each LC Participant thereof.

20

(b) If the LC Bank is required at any time to return to the Seller, or to a trustee, receiver, liquidator, custodian, or any official in any insolvency proceeding, any portion of the payments made by the Seller to the LC Bank pursuant to this Agreement in reimbursement of a payment made under a Letter of Credit or interest or fee thereon, each LC Participant shall, on demand of the LC Bank, forthwith return to the LC Bank the amount of its Pro Rata Share of any amounts so returned by the LC Bank plus interest at the Federal Funds Rate, from the date the payment was first made to such LC Participant through, but not including, the date the payment is returned by such LC Participant.

(d) Funds in the LC Collateral Account will be used to reimburse the LC Bank and (to the extent they have unreimbursed Participation Advances) the LC Participants for fees related to the Letters of Credit and for any draws on the Letters of Credit and Participation Advances which have not reimbursed by the Seller or repaid from Collections. If at any time the amount of the funds on deposit in the LC Collateral Account exceeds 100% of the LC Participation Amount at such time, plus the amount of the Expected LC Fees at such time, the Administrator shall remit an amount equal to such excess to the Servicer to be applied as a Collection of Pool Receivables in accordance with Section 1.4(d) . Any funds on deposit in the LC Cash Collateral Account after all Letters of Credit have expired, all draws on the Letters of Credit have been reimbursed, all Participation Advances have been repaid, all fees due with respect to the Letters of Credit have been paid in full, and the Facility has been terminated, shall be remitted to the Seller.

In the event of a conflict between the Letter of Credit Application and this Agreement, this Agreement shall govern. It is understood and agreed that, except in the case of gross negligence or willful misconduct by the LC Bank, the LC Bank shall not be liable for any error, negligence and/or mistakes, whether of omission or commission, in following the Seller’s instructions or those contained in the Letters of Credit or any modifications, amendments or supplements thereto.

Each such amendment, waiver or consent shall be effective only in the specific instance and for the specific purpose for which it was given. No failure on the part of any Purchaser Agent, any Purchaser or the Administrator to exercise, and no delay in exercising any right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right.

Except as otherwise provided in Section 4.1(d) or 4.1(e) , neither the Seller nor the Servicer may assign or transfer any of its rights or delegate any of its duties hereunder or under any Transaction Document without the prior written consent of each Purchaser Agent.

(b) Participations . Any Purchaser may sell participating interests (each acquirer of a participating interest, a “ participant ”) in its rights and obligations pursuant to this Agreement; provided , however , that the selling Purchaser shall retain all rights and obligations under this Agreement and all parties to this Agreement shall continue to deal solely with such selling Purchaser. Except with respect to participations by Conduit Purchasers pursuant to Section 5.3(i) , each agreement between a Purchaser and a participant shall provide that such Purchaser shall retain the sole right to enforce the Transaction Documents and to approve any amendment, modification or waiver of any provision of this Agreement (other than any amendment, modification or waiver of a provision described in Section 5.1(a) that affects such participant). The Seller agrees that each participant shall be entitled to the benefits of the Sections 1.7 , 1.8 and 1.10 (subject to the requirements and limitations therein, including the requirements under Section 1.10 ; it being understood that the documentation required under Section 1.10(e) shall be delivered to the Purchaser who sells the participation) to the same extent as if it were a Purchaser and had acquired its interest by assignment pursuant to this Section 5.3(b) , provided that such participant (A) agrees to be subject to the provisions of the Sections 5.3(g) and 5.3(h) as if it were an assignee under this Section and (B) shall not be entitled to receive any greater payment under the Section 1.7 or Section 1.10 , with respect to any participation, than the Purchaser from whom it acquired the applicable participation would have been entitled to receive. Each Purchaser that sells a participation agrees, at the Seller’s request and expense, to use reasonable efforts to cooperate with the Seller to effectuate the provisions of Section 5.3(g) with respect to any participant. To the extent permitted by Applicable Law, each participant also shall be entitled to the benefits of any set-off rights provided to the Purchasers under this Agreement as though it were a Purchaser, provided that such Participant agrees to be subject to the provisions of Section 5.15 as though it were a Purchaser. Each Purchaser that sells a participation shall, acting solely for this purpose as an agent of the Seller, maintain a register on which it enters the name and address of each participant and the principal amounts (and stated Discount) of each participant’s interest in the Receivables and rights under this Agreement (the “ Participant Register ”); provided that no Purchaser shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any participant or any information relating to a participant’s interest in any commitments, loans, letters of credit or its other obligations under this Agreement) to any Person except to the extent that such disclosure is necessary to establish

41

that such interest in Receivables and under this Agreement is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Purchaser shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrator shall have no responsibility for maintaining the Participant Register.

(c) Assignments by Purchasers . Each Purchaser may assign, in whole or in part, its interests in the Receivables and its rights or obligations pursuant to this Agreement to any financial or other institution (which, in the case of an assignment by a Related Committed Purchaser, shall be to a financial institution with short-term unsecured debt ratings of at least “A-1” by Standard & Poor’s and “P-1” by Moody’s and that is consented to in writing by the Administrator and the LC Bank, such consent not to be unreasonably withheld or delayed), pursuant to a supplement hereto, substantially in the form of Annex F with any changes as have been approved by the parties thereto (each, a “ Transfer Supplement ”) executed by each such assignee, such selling Purchaser, such related Purchaser Agent and the Administrator; provided that, so long as no Termination Event has occurred and is continuing, any such assignment (other than to another Purchaser or Program Support Provider within its Purchaser Group or conduit managed or sponsored by the same Purchaser Agent) shall require the consent of the Seller. No assignment shall be effective until recorded in the Register. The Administrator, acting solely for this purpose as an agent of the Seller, shall maintain at one of its offices in Pittsburgh, PA a copy of each Transfer Supplement delivered to it and a register for the recordation of the names and addresses of the Purchasers and the Commitments of, and principal amounts (and stated Discount) of the interests in the Receivables and rights under this Agreement owing to each Purchaser pursuant to the terms of this Agreement from time to time (the “ Register ”). The entries in the Register shall be conclusive absent manifest error, and the Seller and the Administrator shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Purchaser hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Seller and any Purchaser, at any reasonable time and from time to time upon reasonable prior notice.

(d) Certain Pledges . Without limiting the right of any Purchaser to sell or grant interests, security interests or participations to any Person as otherwise described in this Section 5.3 , any Purchaser may pledge, or grant a security interest in, all or any portion of its rights under this Agreement to secure its obligations to a Federal Reserve Bank without any notice to, or consent of, the Seller; provided that no such pledge or grant of a security interest shall release a Purchaser from any of its obligations under this Agreement or substitute any such pledgee or grantee for such Purchaser as a party to this Agreement.

(e) Agents . Without limiting any other rights that may be available under Applicable Law, the rights of the Purchasers and each Liquidity Provider may be enforced through it or by its agents, including its related Purchaser Agents.

42

(f) Disclosure; Notice . Each assignor may, in connection with an assignment permitted hereunder, disclose to the applicable assignee (that shall have agreed to be bound by an agreement containing a confidentiality undertaking in substantially the form set forth in Section 5.6 ) any information relating to the Servicer, the Seller or the Pool Receivables furnished to such assignor by or on behalf of the Servicer, the Seller, any Purchaser, any Purchaser Agent or the Administrator. Such assignor shall give prior written notice to the Seller of any assignment of such assignor’s rights and obligations (including ownership of the Purchased Interest) to any Person other than a Program Support Provider.

(g) Replacement of Purchasers . If (a) the Seller receives a claim for compensation under Section 1.7 or Section 1.10 of this Agreement from any Purchaser (or its Liquidity Provider or Program Support Provider), (b) any Purchaser is a Defaulting Purchaser, or (c) any Purchaser does not consent to a request to extend the Scheduled Termination Date, then the Seller may, at its sole expense and effort, upon notice to such Purchaser, its related Purchaser Agent and the Administrator, require such Purchaser, its related Purchaser Agent and any other Purchaser in such Purchaser’s Purchaser Group to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 5.3(c) or (j) , as applicable, of this Agreement), all of their respective interests, rights (other than their existing rights to payment under Sections 1.7 and 1.10 of this Agreement) and obligations under this Agreement and the other Transaction Documents, to an assignee that shall assume such obligations (which assignee may be a member of an existing Purchaser Group, if such Person accepts such assignment); provided , however , that the Seller shall be permitted to require the assignment by (i) the Purchaser Group of which the Administrator is a member, or (ii) any Purchaser which is administered by the Administrator or an Affiliate thereof only if, in either case, the Administrator is also replaced contemporaneously, pursuant to documents reasonably satisfactory to the Administrator; provided , further , that (i) the assignee financial institution shall purchase, at par, all Capital, Discount and other amounts owing to such assigning Purchaser and Purchaser Agent (other than any amounts owing under Sections 1.7 and 1.10 of this Agreement for which payment is then sought) on or prior to the date of assignment, (ii) if the replacement financial institution is not already a member of an existing Purchaser Group, the Seller shall have received the written consent of the Administrator and the LC Bank (which consents shall not be unreasonably withheld or delayed) to such assignment, (iii) until such time as such assignment shall be consummated, the Seller shall pay all additional amounts required under Sections 1.7 and 1.10 , subject to the terms of this Agreement, (iv) such assignment shall not conflict with Applicable Law, (v) any such assignment shall not be deemed to be a waiver of any right that the Seller, the Administrator, any Purchaser Agent or any other Purchaser shall have against the assignor Purchaser or any member of its Purchaser Group and (vi) any such assignment by a Related Committed Purchaser shall be to a financial institution with short-term unsecured debt ratings of at least A-1 by Standard & Poor’s and “P-1” by Moody’s. No Purchaser or Purchaser Group may be required to make an assignment pursuant to this Section 5.3(g) (i) at any time when there is only one Purchaser Group or (ii) if the condition that gave rise to the Seller’s right to require such assignment ceases to apply.

(h) Mitigation Obligations . If any Affected Person requests compensation under Section 1.7 , or if the Seller is required to pay any additional amount to any Affected Person or any Governmental Authority for the account of any Affected Person pursuant to Section 1.10 , then such Affected Person shall (at the request of the Seller) use reasonable efforts to designate a different office for funding or booking its Purchases hereunder or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates, if, in the judgment of such

43

Affected Person, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 1.7 or 1.10 , as the case may be, in the future and (ii) would not subject such Affected Person to any unreimbursed cost or expense and would not otherwise be materially disadvantageous to such Affected Person. The Seller hereby agrees to pay all reasonable costs and expenses incurred by any Affected Person in connection with any such designation or assignment; provided , that such Affected Person is generally seeking compensation from similarly situated borrowers under similar trade receivables securitization facilities (to the extent such Affected Person has the right under such similar facilities to do so).

(i) Assignments to Liquidity Providers and other Program Support Providers . Any Conduit Purchaser may at any time grant to one or more of its Liquidity Providers or other Program Support Providers participating interests in its portion of the Purchased Interest. In the event of any such grant by such Conduit Purchaser of a participating interest to a Liquidity Provider or other Program Support Provider, such Conduit Purchaser shall remain responsible for the performance of its obligations hereunder. The Seller agrees that each Liquidity Provider and Program Support Provider shall be entitled to the benefits of Sections 1.7 and 1.8 .

(j) Other Assignment by Conduit Purchasers . Each party hereto agrees and consents (i) to any Conduit Purchaser’s assignment, participation, grant of security interests in or other transfers of any portion of, or any of its beneficial interest in, the Purchased Interest (or portion thereof), including without limitation to any collateral agent in connection with its commercial paper program and (ii) to the complete assignment by any Conduit Purchaser of all of its rights and obligations hereunder to any Liquidity Provider or Related Committed Purchaser for such Conduit Purchaser or to any other Person; provided , that such Conduit Purchaser may not, without the prior consent of its Related Committed Purchasers and, so long as no Termination Event is continuing, of the Seller (which consent the Seller may grant or withhold in its sole discretion), make any such assignment of its rights hereunder unless the assignee (x) is a commercial paper conduit that (i) is principally engaged in the purchase of assets similar to the assets being purchased hereunder, (ii) has as its Purchaser Agent the Purchaser Agent of the assigning Conduit Purchaser and (iii) issues commercial paper or other Notes with credit ratings substantially comparable to the ratings of the assigning Conduit Purchaser or (y) is a Related Committed Purchaser or Liquidity Provider for such Conduit Purchaser.

representation and warranty that such interest is being sold by each such other Purchaser free and clear of any Adverse Claim created or granted by such other Purchaser, in the amount necessary to create proportional participation by the Purchaser in such recovery.

Section 5.16 Defaulting Purchasers .

(a) If any LC Participant becomes a Defaulting Purchaser at any time when there are undrawn Letters of Credit outstanding, then all or any part of such Defaulting Purchaser’s participation in such Letters of Credit shall be reallocated among the LC Participants that are not Defaulting Purchasers in accordance with their respective Pro Rata Shares (calculated without regard to such Defaulting Purchaser’s Commitment), but only to the extent that (x) the conditions precedent to issuance of Letters of Credit are satisfied at the time of such reallocation (and, unless the Seller shall have otherwise notified the Administrator at such time, the Seller shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the aggregate credit exposure of any Purchaser to exceed such Purchaser’s Commitment. No such reallocation shall constitute a waiver or release of any claim of any party against a Defaulting Purchaser arising from that Purchaser having become a Defaulting Purchaser, including any claim of any other Purchaser as a result of such other Purchaser’s increased exposure following such reallocation.

(b) If any LC Participant becomes a Defaulting Purchaser at any time when there are undrawn Letters of Credit outstanding and the reallocation described in Section 5.16(a) above cannot, or can only partially, be effected, then the Seller shall (i) within two (2) Business Days following notice by the LC Bank, cash collateralize for the benefit of the LC Bank a portion of the amount of the then outstanding Letters of Credit equal to such Defaulting Purchaser’s Pro Rata Share (determined after giving effect to any reallocation of its participation in Letters of Credit pursuant to Section 5.16(a) above) of the undrawn stated amount of outstanding Letters of Credit by depositing such amount into the LC Collateral Account, and (ii) maintain funds in the LC Collateral Account to cash collateralize such Defaulting Purchaser’s Pro Rata Share (determined after giving effect to any reallocation of its participation in Letters of Credit pursuant to Section 5.16(a) above) of the undrawn stated amount of outstanding Letters of Credit. The Administrator shall apply funds deposited into the LC Collateral Account to satisfy a Defaulting Purchaser’s obligation to fund its portion of a Reimbursement Purchase requested or deemed requested by the Seller and to fund any Participation Advance required to be made by such Defaulting Purchaser.

(c) The Seller shall not be required to pay such Defaulting Purchaser any fees payable with respect to the amount of the undrawn Letters of Credit that is so cash collateralized by the Seller.

(d) No amount payable by the Seller for the account of a Defaulting Purchaser (whether on account of Capital, Discount, indemnity payments or other amounts) shall be paid or distributed to such Defaulting Purchaser (or its Purchaser Agent), but instead shall be deposited

49

to the LC Collateral Account until the amount therein is equal to the amount of such Defaulting Purchaser’s Pro Rata Share of the stated amount of the undrawn Letters of Credit that is not cash collateralized, and to the extent of any remaining amounts, to pay to such Defaulting Purchaser amounts owed to it. Notwithstanding any provision herein or in any Fee Letter to the contrary, if any Related Committed Purchaser becomes a Defaulting Purchaser, for so long as such Related Committed Purchaser is a Defaulting Purchaser, Commitment Fees (as defined in the RPA Fee Letter) shall cease to accrue on the Commitment of such Defaulting Purchaser.

(e) No Defaulting Purchaser shall have any right to approve or disapprove any amendment, waiver or consent under this Agreement (and any amendment, waiver or consent which by its terms requires the consent of all Purchasers or each affected Purchaser may be effected with the consent of the applicable Purchasers other than Defaulting Purchasers), except that (x) the Commitment of any Defaulting Purchaser may not be increased or extended without the consent of such Purchaser and (y) any waiver, amendment or modification requiring the consent of all Purchasers or each affected Purchaser that by its terms affects any Defaulting Purchaser more adversely than other affected Purchasers shall require the consent of such Defaulting Purchaser.

For purposes of this Agreement and all such certificates and other documents delivered in connection herewith, unless the context otherwise requires or unless otherwise specifically provided herein: (a) except as otherwise expressly provided herein, all terms of an accounting or financial nature shall be construed in accordance with GAAP, as in effect from time to time (subject to the immediately succeeding paragraph); (b) all terms used in Article 9 of the UCC in the State of New York, and not specifically defined herein, are used herein as defined in such Article 9; (c) references to any amount as on deposit or outstanding on any particular date means such amount at the close of business on such day; (d) the words “hereof,” “herein” and “hereunder” and words of similar import refer to such agreement (or the certificate or other document in which they are used) as a whole and not to any particular provision of such agreement (or such certificate or document); (e) references to any Section, Annexes, Schedule or Exhibit are references to Sections, Annexes, Schedules and Exhibits in or to such agreement (or the certificate or other document in which the reference is made), and references to any paragraph, subsection, clause or other subdivision within any Section or definition refer to such paragraph, subsection, clause or other subdivision of such Section or definition; (f) the term “including” means “including without limitation”; (g) references to any Applicable Law refer to that Applicable Law as amended from time to time and include any successor Applicable Law; (h) references to any agreement refer to that agreement as from time to time amended, restated or supplemented or as the terms of such agreement are waived or modified in accordance with its terms; (i) references to any Person include that Person’s permitted successors and assigns; (j) headings are for purposes of reference only and shall not otherwise affect the meaning or interpretation of any provision hereof; (k) unless otherwise provided, in the calculation of time from a specified date to a later specified date, the term “from” means “from and including”, and the terms “to” and “until” each means “to but excluding”; (l) terms in one gender include the parallel terms in the neuter and opposite gender; and (m) the term “or” is not exclusive.

No delay by the Seller or the Majority Purchaser Agents in requiring such negotiation shall limit their right to so require such a negotiation at any time after such a change in accounting principles. Until any such covenant,

51

standard, or term is amended in accordance with this Section 5.20 , financial covenants shall be computed and determined in accordance with GAAP in effect prior to such change in accounting principles. Obligations relating to a lease that was accounted for by a Person as an operating lease before such change in GAAP and any similar lease entered into after such change in GAAP shall be accounted for as obligations relating to an operating lease and not as a capital lease.
