In connection therewith, the Borrower intends to obtain (a) a 364-day senior unsecured bridge term loan credit facility (the “Bridge Facility”) in an aggregate principal amount of up to $26,500,000,000 (as such amount may be reduced as set forth in the Bridge Term Sheet, including by the amount of any Term Facilities committed under the Term Facilities Documentation) and (b) senior unsecured term loan facilities comprised of:

(i) a tranche of senior unsecured term loans with a three year maturity in an aggregate principal amount of up to $2,000,000,000 (the “Three Year Tranche”) and (ii) a tranche of senior unsecured term loans with a five year maturity in an aggregate principal amount of up to $2,000,000,000 (the “Five Year Tranche” and, together with the Three Year Tranche, the “Term Facilities”; the Term Facilities, together with the Bridge Facility, the “Facilities”). The date of consummation of the Acquisition is referred to herein as the “Closing Date.” All capitalized terms used and not otherwise defined herein shall have the same meanings as specified therefor in the Term Sheets.

It is further agreed that (i) BofAML shall have “left placement” in any offering and marketing materials for the Facilities, and shall hold the roles and responsibilities conventionally understood to be associated with such placement and (ii) the Lead Arrangers other than BofAML will appear in any offering and marketing materials for the Facilities in the following order: Credit Suisse and UBS. You further agree that no other titles will be awarded and no compensation (other than that expressly contemplated by this Commitment Letter and the Fee Letter (as hereinafter defined)) will be paid in order to obtain commitments in connection with any Facility unless you and we shall so agree; provided that, in connection with the syndication of the Facilities, at any time on or prior to the 15^th business day following the date of this Commitment Letter, you may (in consultation with the Lead Arrangers), appoint up to two financial institutions reasonably acceptable to the Lead Arrangers to act as co-documentation

2

agents, co-managers or other similar roles (but not joint lead arrangers, joint bookrunners or co-syndication agents) for each of the Facilities (the “Additional Agents”) in a manner and with economics determined by you and us (it being understood that, (i) each such Additional Agent (or its affiliates) shall assume at least a proportion of the commitments with respect to each Facility that is equal to the proportion of the economics (if any) allocated to such Additional Agent (or its affiliates) with respect to such Facility and Schedule I hereto shall be automatically amended accordingly, (ii) to the extent Additional Agents are appointed in respect of the Bridge Facility, the economics (if any) allocated to and the Bridge Commitments of the Commitment Parties party hereto on the date hereof in respect of the Bridge Facility, will be reduced ratably by the commitments of such appointed entities upon the execution and delivery by such Additional Agent of a Joinder Agreement (as defined below) or the applicable Credit Documentation for the Bridge Facility, (iii) to the extent Additional Agents are appointed in respect of the Term Facilities, the economics (if any) allocated to and the Term Commitments of the Commitment Parties party hereto on the date hereof in respect of the Term Facilities, will be reduced ratably by the commitments of such appointed entities upon the execution and delivery by such Additional Agent of a Joinder Agreement or the applicable Credit Documentation for the Term Facilities and (iv) no Additional Agent shall receive greater total compensatory economics with respect to any Facility than those individually received by each Commitment Party party hereto on the date hereof.

The commitments of the Initial Lenders in respect of the Facilities and the undertaking of the Lead Arrangers to provide the services described herein are subject to the satisfaction of each of the conditions precedent set forth herein and in the Term Sheets (it being understood that the commitments of the Initial Lenders hereunder in respect of the Facilities are subject only to the conditions set forth in Section 5 of the Commitment Letter and in Exhibit C attached to this Commitment Letter).

2.        Syndication.  The Lead Arrangers intend to commence syndication of the Facilities promptly after your acceptance of the terms of this Commitment Letter and the Fee Letter and the several commitments of the Commitment Parties hereunder shall be reduced (a) in respect of the Bridge Facility, dollar-for-dollar on a pro-rata basis as and when corresponding commitments are received from the Bridge Lenders in compliance with Section 8 hereof and (b) in respect of the Term Facilities, as determined by the Lead Arrangers after full subscription of 71.25% of the aggregate principal amount of the Three Year Tranche in commitments in respect of the Three Year Tranche and 71.25% of the aggregate principal amount of the Five Year Tranche in commitments in respect of the Five Year Tranche that are not committed to by the Initial Term Lenders hereunder, upon the allocation of the commitments in respect of the applicable Facility, in each case, pursuant to a Joinder Agreement or pursuant to the applicable Credit Documentation in respect of such Facility. Until the earlier of (i) 60 days following the Closing Date and (ii) the completion of a Successful Syndication (as defined in the Fee Letter) (such date, the “Syndication Date”), you agree to actively assist, and to use your commercially reasonable efforts to cause the Acquired Business and its subsidiaries to actively assist, the Lead Arrangers in achieving a Successful Syndication (as defined in the Fee Letter). Such assistance shall include, in each case, subject to compliance with state and federal laws, rules and regulations: (a) subject to the limitations in the immediately succeeding paragraph, your providing and causing your advisors to provide, and using your commercially reasonable efforts to cause the Acquired Business, its subsidiaries and their respective advisors to provide, the Lead

3

Arrangers and the Lenders upon reasonable request with all information reasonably deemed necessary by the Lead Arrangers to complete such syndication, including, but not limited to, information and evaluations prepared by you, the Acquired Business and your and its advisors, or on your or its behalf, relating to the Transactions (including the Projections (as hereinafter defined)), (b) your assistance in the preparation of a confidential information memorandum with respect to the Facilities in form and substance customary for transactions of this type and otherwise reasonably satisfactory to the Lead Arrangers (each, an “Information Memorandum”) and other customary marketing materials to be used in connection with the syndication of the Facilities (collectively with the Term Sheets and any additional summary of terms prepared for distribution to Public Lenders (as hereinafter defined), the “Information Materials”), (c) your using your commercially reasonable efforts to ensure that the syndication efforts of the Lead Arrangers benefit from your existing lending relationships and, to the extent practical and appropriate, the existing banking relationships of the Acquired Business, (d) your using commercially reasonable efforts to execute and deliver one or more Joinder Agreements (as hereinafter defined) delivered to you in respect of any Permitted Assignee (as hereinafter defined), as soon as reasonably practicable following commencement of syndication of the Bridge Facility, (e) using your commercially reasonable efforts to maintain a Public Debt Rating (after giving effect to the Transactions but not a specific rating) of the Borrower from each of Moody’s Investors Service, Inc. (“Moody’s”) and Standard & Poor’s Financial Services LLC, a subsidiary of The McGraw Hill Corporation (“S&P”) until the Syndication Date, and (f) your otherwise assisting the Lead Arrangers in their syndication efforts, including by making your officers and advisors, and using your commercially reasonable efforts to make the officers and advisors of the Acquired Business, available from time to time to attend and make presentations at one or more meetings of prospective Lenders at times and places to be mutually agreed.

For the avoidance of doubt, nothing contained in this Commitment Letter shall require you to provide any information to the extent that the provision thereof would violate any attorney-client privilege, law, rule or regulation, or any obligation of confidentiality binding on you, the Acquired Business or your or its respective affiliates; provided that (x) in the case of any confidentiality obligation, you shall have used commercially reasonable efforts to obtain consent to provide such information and (y) you shall notify us if any such information is being withheld as a result of any such obligation of confidentiality (but solely if providing such notice would not violate such confidentiality obligation).

You further agree to use commercially reasonable efforts to (1) deliver to one or more investment banks appointed by you to place or sell the Takeout Securities (collectively the “Investment Bank”), not later than 10 business days prior to the Closing Date, a complete preliminary prospectus supplement, preliminary offering memorandum or preliminary private placement memorandum (collectively, an “Offering Document”) (and at no time during the 10 business day period shall the financial information in such Offering Document become stale) suitable for use in a customary offering registered under the Securities Act of 1933, as amended, or pursuant to Rule 144A thereunder relating to the Takeout Securities, which contains all financial statements and other data required to be included therein or customarily included therein (including all audited annual financial statements, including target financial statements and all unaudited quarterly financial statements (which shall have been reviewed by your independent accountants as provided in the procedures specified by the Public Company Accounting Oversight Board in AU 722) prepared in accordance with, or reconciled to, generally

4

accepted accounting principles in the United States and prepared in accordance with Regulation S-X under the Securities Act of 1933, as amended) and all required pro forma financial statements and all other data (including selected financial data) that the Securities and Exchange Commission would require in a registered offering of the applicable Takeout Securities or that would be necessary for the Investment Banks to receive customary “comfort” (including “negative assurance” comfort) from the Borrower’s independent accountants, the Acquired Business’ independent accountants and any other applicable accountants (including, without limitation, any relevant predecessor accountant or acquired company accountant) in connection with the applicable Takeout Securities, (2) arrange to deliver at the closing of such placement or sale (A) a customary comfort letter (which shall provide “negative assurance” comfort) from the Borrower’s independent accountants, the Acquired Business’ independent accountants and any other applicable accountants (including, without limitation, any relevant predecessor accountant or acquired company accountant) and (B) a customary “10b-5” legal opinion or disclosure letter from your counsel, and (3) cause the senior management and other representatives of the Borrower and, in a manner consistent with the terms of the Acquisition Agreement, the Acquired Business, to provide access in connection with due diligence investigations and to prepare and participate in a customary “road show”.

In order to facilitate an orderly and successful syndication of the Facilities, you agree that until the Syndication Date, the Borrower and its subsidiaries shall not, and shall use commercially reasonable efforts to ensure that the Acquired Business and its subsidiaries shall not, issue, announce, offer, place or arrange debt or equity securities or any syndicated credit facilities of the Borrower, the Acquired Business or their respective subsidiaries (other than (i) the Senior Notes, (ii) amendments to, or the refinancing or replacement of, your Existing Credit Agreement (including any increases in the amount thereof up to an aggregate principal amount of such increases not to exceed $1,500,000,000), (iii) issuances of commercial paper, (iv) indebtedness permitted to be incurred by the Acquired Business and its subsidiaries pursuant to the Acquisition Agreement, (v) indebtedness incurred in the ordinary course of business, including, without limitation, borrowings under existing credit facilities and refinancings of existing indebtedness that matures prior to the date that is 6 months after the Syndication Date, (vi) indebtedness incurred to pay cash consideration in connection with any exercise of conversion rights by the holders of the Borrower’s 2.750% Senior Convertible Debentures due 2042, (vii) other debt in an aggregate principal amount not to exceed in excess of $100,000,000, (viii) equity securities issued pursuant to employee stock option or purchase plans, (ix) issuances of equity to the shareholders and option holders of the Acquired Business in connection with the Acquisition, (x) equity issued to sellers as consideration for any other acquisition by the Borrower or its subsidiaries and (xi) any other debt or equity financing agreed by the Lead Arrangers), in each case if such issuance, announcement, offering, placement or arrangement could reasonably be expected to materially impair the primary syndication of any Facility.

It is understood and agreed that the Lead Arrangers will manage and control all aspects of the syndication of the Facilities in consultation with you (subject, however, to your rights to appoint Additional Agents as provided above and the proviso below), including decisions as to the selection of prospective Lenders and any titles offered to proposed Lenders, when commitments will be accepted and the final allocations of the commitments among the Lenders; provided that the Lead Arrangers will not syndicate to any person (other than those financial institutions (and their affiliates) identified by the Lead Arrangers to you in writing on

5

or prior to the date hereof and to lenders under the Existing Credit Agreement (other than a “defaulting lender” under and as defined therein, as of the date such syndication) without your consent (such consent not to be unreasonably withheld or delayed). It is understood that no Lender participating in the Facilities will receive compensation from you in order to obtain its commitment, except on the terms contained herein and in the Term Sheets and the Fee Letter. It is also understood and agreed that the amount and distribution of the fees among the Lenders will be at the sole and absolute discretion of the Lead Arrangers.

Notwithstanding anything to the contrary contained in this Commitment Letter or any other agreement or undertaking concerning the Facilities, but without limiting your obligations to assist with syndication in this Section 2, none of the foregoing obligations under the provisions of this Section 2 nor the commencement, conduct or completion of the syndication contemplated by this Section 2 is a condition to the commitments or the funding of the Facilities on the Closing Date.

Notwithstanding the Lead Arranger’s right to syndicate the Facilities and receive commitments with respect thereto, except in each as provided above with respect to the appointment by you of Additional Agents or assignments made as expressly provided in Section 8, (i) no Initial Lender shall be relieved, released or novated from its obligations hereunder (including, subject to the satisfaction of the conditions set forth herein, its obligation to fund the Facilities on the Closing Date) in connection with any syndication, assignment or participation of the Facilities, including its commitments in respect thereof, until after the Closing Date has occurred, (ii) no assignment or novation by an Initial Lender shall become effective as between you and such Initial Lender with respect to all or any portion of such Initial Lender’s commitments in respect of the Facilities until the initial funding of the Facilities and (iii) unless you otherwise agree in writing, each Initial Lender shall retain exclusive control over all rights and obligations with respect to its commitments in respect of the Facilities, including all rights with respect to consents, modifications, supplements, waivers and amendments, until after the Closing Date has occurred.

3.        Information Requirements. You hereby represent and warrant that (a) all written information, other than Projections (as defined below), forward-looking information and other information of a general economic or industry nature (the “Information”), that has been or is hereafter made available to the Lead Arrangers or any of the Lenders by or on behalf of you or any of your representatives in connection with any aspect of the Transactions (which representation and warranty shall be to your knowledge to the extent it relates to the Acquired Business or its subsidiaries), when taken as a whole, is and will be when furnished (with your SEC filings and those of the Acquired Business being deemed made available for purposes hereof at the time of the filing thereof) complete and correct in all material respects and does not and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein not materially misleading in light of the circumstances under which such statements were made or are made, when taken as a whole (giving effect to all supplements and updates provided thereto) and (b) all financial projections concerning the Borrower, the Acquired Business and their respective subsidiaries that have been or are hereafter made available to the Lead Arrangers or any of the Lenders by or on behalf of you or any of your representatives (the “Projections”) have been or will be prepared in good faith based upon assumptions that were believed by the Borrower to be reasonable as of the date

6

such Projections are prepared and as of the date such Projection are made available to the Lead Arrangers (it being understood that the Projections are as to future events and are not to be viewed as facts, the Projections are subject to significant uncertainties and contingencies, many of which are beyond your control, that no assurance can be given that any particular Projections will be realized and that actual results during the period or periods covered by any such Projections may differ significantly from the projected results and such differences may be material). You agree that if at any time prior to the Syndication Date, you become aware that any of the representations in the preceding sentence would be incorrect in any material respect (prior to the Closing Date, to your knowledge with respect to Information and forward looking information relating to the Acquired Business) if the Information and Projections were being furnished, and such representations were being made, at such time, then you will promptly supplement, or cause to be supplemented, the Information and Projections so that such representations (prior to the Closing Date, to your knowledge with respect to Information and forward looking information relating to the Acquired Business) will be correct in all material respects at such time. The accuracy of the foregoing representations and warranties, whether or not cured or supplemented, shall not be a condition to the obligations of any of the Initial Lenders hereunder. In issuing this commitment and in arranging and syndicating the Facilities, the Commitment Parties are and will be using and relying on the Information and the Projections without independent verification thereof.

You acknowledge that (a) the Lead Arrangers on your behalf will make available Information Materials to the proposed syndicate of Lenders by posting the Information Materials on IntraLinks or another similar electronic system and (b) certain prospective Lenders (such Lenders, “Public Lenders”; all other Lenders, “Private Lenders”) may have personnel that do not wish to receive material non-public information (within the meaning of the United States federal and state securities laws, “MNPI”) with respect to the Borrower, the Acquired Business, their respective affiliates or any other entity, or the respective securities of any of the foregoing, and who may be engaged in investment and other market-related activities with respect to such entities’ securities. If requested, you will assist us in preparing an additional version of the Information Materials not containing MNPI (the “Public Information Materials”) to be distributed to prospective Public Lenders.

Before distribution of any Information Materials to (a) prospective Private Lenders, you shall provide us with a customary letter authorizing the dissemination of the Information Materials and (b) prospective Public Lenders, you shall provide us with a customary letter authorizing the dissemination of the Public Information Materials and confirming the absence of MNPI therefrom. In addition, at our request, you shall identify Public Information Materials by clearly and conspicuously marking the same as “PUBLIC”.

You agree that the Lead Arrangers on your behalf may distribute the following documents to all prospective Lenders, unless you advise the Lead Arrangers in writing (including by email) within a reasonable time prior to their intended distributions that such material should only be distributed to prospective Private Lenders: (a) administrative materials for prospective Lenders such as lender meeting invitations and funding and closing memoranda, (b) notifications of changes to the terms of any Facility and (c) drafts and final versions of definitive documents with respect to the Facilities. If you advise us that any of the foregoing items should be distributed only to Private Lenders, then the Lead Arrangers will not distribute such materials to

7

Public Lenders without further discussions with you. You agree that Information Materials made available to prospective Public Lenders in accordance with this Commitment Letter shall not contain MNPI.

4.        Fees and Indemnities.

(a)      You agree to pay, or cause to be paid, the fees set forth in the separate fee letter addressed to you dated the date hereof from the Commitment Parties (the “Fee Letter”). You also agree to reimburse the Commitment Parties from time to time, upon presentation of a summary statement (in reasonable detail), for all reasonable and documented out-of-pocket fees and expenses (including, but not limited to, the reasonable fees, disbursements and other charges of counsel which shall be limited to the reasonable and documented out-of-pocket fees and other charges of one counsel acting collectively on behalf of the Lead Arrangers and the Administrative Agents, and, if necessary, of one regulatory counsel and one local counsel retained by the Lead Arrangers and the Administrative Agents in each relevant regulatory field and each relevant jurisdiction, respectively (and, in the case of an actual or perceived conflict of interest where the Commitment Party affected by such conflict notifies you of the existence of such conflict and thereafter retains its own counsel, of another firm of counsel for each such affected Commitment Party), and due diligence expenses) incurred in connection with the Facilities, the syndication thereof, the preparation of the Credit Documentation (as hereinafter defined) therefor and the other transactions contemplated hereby, whether or not the funding of any Facility occurs or any Credit Documentation is executed and delivered or any extensions of credit are made under the Facilities. You acknowledge that we may receive a benefit, including without limitation, a discount, credit or other accommodation, from any of such counsel based on the fees such counsel may receive on account of their relationship with us including, without limitation, fees paid pursuant hereto.

(b)      You also agree to indemnify and hold harmless each of the Commitment Parties, each other Lender and each of their affiliates and controlling persons, successors and assigns and their respective officers, directors, employees, agents, advisors and other representatives (each, an “Indemnified Party”) from and against (and will reimburse each Indemnified Party as the same are incurred for) any and all claims, damages, losses, liabilities and expenses (including, without limitation, the reasonable fees, disbursements and other charges of counsel (but limited, in the case of legal fees and expenses, to the reasonable and documented out-of-pocket fees and expenses of one counsel, representing all of the Indemnified Parties, taken as a whole, and, if necessary, of a single local counsel in each relevant regulatory field and each relevant jurisdiction (which may include a single special counsel acting in multiple regulatory fields and/or jurisdictions) for all such Indemnified Parties, taken as whole (and, in the case of an actual or perceived conflict of interest where the Indemnified Party affected by such conflict notifies you of the existence of such conflict and thereafter retains its own counsel, of another firm of counsel for each such affected Indemnified Party))) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or by reason of any investigation, litigation or proceeding (or preparation of a defense in connection therewith) relating to or arising out of (a) any aspect of the Transactions or any similar transaction and any of the other transactions contemplated thereby or (b) the Facilities or any use made or proposed to be made with the proceeds thereof, except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent

8

jurisdiction to have resulted from (x) such Indemnified Party’s gross negligence, bad faith or willful misconduct, (y) such Indemnified Party’s material breach of this Commitment Letter, the Fee Letter or any of the Credit Documentation or (z) disputes solely among Indemnified Parties not arising from or in connection with any act or omission by the Borrower or any of its affiliates (other than any Proceedings (as hereinafter defined) against a Commitment Party in its capacity or in fulfilling its role as an administrative agent or arranger or other similar role under any Facility). In the case of any claim, litigation, investigation or proceeding (any of the foregoing, a “Proceeding”) to which the indemnity in this paragraph applies, such indemnity shall be effective whether or not such Proceeding is brought by you, your equity holders or creditors, the Acquired Business or their subsidiaries, affiliates or equity holders, or an Indemnified Party, whether or not an Indemnified Party is otherwise a party thereto and whether or not any aspect of the Transactions is consummated. You also agree that no Indemnified Party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to you, or your subsidiaries or affiliates or to your respective equity holders or creditors arising out of, related to or in connection with any aspect of the Transactions, except to the extent of direct (as opposed to special, indirect, consequential or punitive) damages determined in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence, bad faith or willful misconduct. It is further agreed that the Commitment Parties shall only have liability to you (as opposed to any other person), and that the Commitment Parties shall be severally liable solely in respect of their respective commitments under the Facilities, on a several, and not joint, basis with any other Lender. Notwithstanding any other provision of this Commitment Letter, no party hereto and no Indemnified Party shall be liable for any indirect, special, punitive or consequential damages in connection with its activities relating to any Facility. Notwithstanding any other provision of this Commitment Letter, no party hereto and no Indemnified Party shall be liable for any damages arising from the use by others of information or other materials obtained through electronic telecommunications or other information transmission systems, other than for direct, actual damages resulting from the gross negligence, bad faith or willful misconduct of such party hereto or such Indemnified Party as determined by a final, non-appealable judgment of a court of competent jurisdiction. You shall not be liable for any settlement of any Proceeding effected without your prior written consent (which consent shall not be unreasonably withheld or delayed), but if settled with your prior written consent or if there is a final judgment in any such Proceeding, you agree to indemnify and hold harmless each Indemnified Party from and against any and all losses, claims, damages, liabilities and expenses by reason of such settlement or judgment in accordance with this Section 4. You shall not, without the prior written consent of an Indemnified Party (which consent shall not be unreasonably withheld), effect any settlement of any pending or threatened Proceeding against an Indemnified Party in respect of which indemnity could have been sought hereunder by such Indemnified Party unless such settlement (i) includes an unconditional release of such Indemnified Party from all liability or claims that are the subject matter of such Proceeding and (ii) does not include any statement as to any admission of fault by or on behalf of such Indemnified Party.

5.        Conditions to Financing. Each Initial Lender’s commitment hereunder, and each of our agreements to perform the services described herein, are subject solely to satisfaction or waiver of each of the following conditions precedent: (a) at any time on or after the date of the Acquisition Agreement, there shall not have occurred any event, change, effect, development or occurrence that has had or would reasonably be expected to have, individually or

9

in the aggregate, a Material Adverse Effect (as defined below) on the Acquired Business, (b) the negotiation, execution and delivery of the Credit Documentation with respect to the Facilities consistent with this Commitment Letter and the Fee Letter and the applicable Documentation Principles, and (c) the satisfaction or waiver by the Initial Lenders of the conditions set forth on Exhibit C. For the purposes hereof, “Material Adverse Effect” means, with respect to any Person, any event, change, effect, development or occurrence that has a material adverse effect on the business, results of operations or financial condition of such Person and its Subsidiaries, taken as a whole; provided, however, that no event, change, effect, development or occurrence shall be deemed to constitute, nor shall any of the foregoing be taken into account in determining whether there has been, a Material Adverse Effect, to the extent that such event, change, effect, development or occurrence results from or arises out of: (i) any changes in conditions generally affecting the healthcare, health insurance or managed care industry or any other industry in which such Person and any of its Subsidiaries operate, except to the extent that any such changes have a materially disproportionate effect on such Person and its Subsidiaries, taken as a whole, relative to the effect such changes have on others operating in the industries in which such Person and any of its Subsidiaries operate, (ii) any decline, in and of itself, in the market price or trading volume of the common stock of such Person or in its credit ratings (it being understood that the foregoing shall not preclude any assertion that the facts or occurrences giving rise to or contributing to such decline that are not otherwise excluded from the definition of Material Adverse Effect should be deemed to constitute, or be taken into account in determining whether there has been, or would reasonably be expected to be, a Material Adverse Effect), (iii) any general economic or political conditions or securities, credit, financial or other capital markets conditions, in each case in the United States or any foreign jurisdiction, except to the extent that such changes or conditions have a materially disproportionate effect on such Person and its Subsidiaries, taken as a whole, relative to the effect such changes or conditions have on others operating in the industries in which such Person and any of its Subsidiaries operate, (iv) any failure, in and of itself, by such Person to meet any internal or published projections, forecasts, estimates or predictions in respect of revenues, earnings or other financial or operating metrics for any period (it being understood that the foregoing shall not preclude any assertion that the facts or occurrences giving rise to or contributing to such failure that are not otherwise excluded from the definition of Material Adverse Effect should be deemed to constitute, or be taken into account in determining whether there has been, or would reasonably be expected to be, a Material Adverse Effect), (v) the execution and delivery of the Acquisition Agreement or the public announcement or pendency of the transactions contemplated by the Acquisition Agreement, including the impact thereof on the relationships, contractual or otherwise, of such Person or any of its Subsidiaries with customers, providers, suppliers, partners or employees (it being understood that the foregoing shall not apply with respect to any representation or warranty that is intended to address the consequences of the execution, delivery or performance of the Acquisition Agreement or the consummation of the transactions contemplated thereby), (vi) any change in any applicable rule, regulation, ordinance, statute or any other law of or by any Governmental Entity after the date of the Acquisition Agreement, except to the extent that any such changes have a materially

10

16

with respect to the commitments, any assignments thereof to an affiliate or branch will not relieve an Initial Lender making such assignment from any of its obligations hereunder unless and until such affiliate or branch shall have funded the portion of the commitment so assigned on the Closing Date.
