Capitalized terms used but not defined in this letter agreement (together with the annexes attached hereto, this “Commitment Letter”) shall have the meanings assigned thereto in the annexes hereto.

1.Commitments; Engagement of the Arrangers; Titles and Roles.

In connection with the Transactions, CS is pleased to advise you of its commitment to, and hereby agrees to provide, 100% of the Facilities (in such capacity, the “Initial Lender” and collectively with any relevant Additional Commitment Parties appointed pursuant to Section 1 hereof, the “Initial Lenders”).

You hereby appoint CSLF to act, and CSLF hereby agrees to act (or to designate one or more of its affiliates to act), as lead arranger and bookrunner for the Facilities, in each case upon the terms and subject to the conditions set forth or referred to in this Commitment Letter (in such capacity, each an “Arranger” and collectively with any relevant Additional Commitment Parties appointed pursuant to Section 1 hereof, the “Arrangers”). CSLF will have “left” placement in any marketing materials or other documentation used in connection with the Facilities, and have the role customarily associated with acting as “lead left” with respect thereto.

Each Arranger, in such capacities, will perform the duties and exercise the authority customarily performed and exercised by it in such roles. In its capacity as a lead arranger and bookrunner, each Arranger agrees to use its commercially reasonable efforts to arrange a syndicate of banks, financial institutions and other institutional lenders (the “Lenders”) that will participate in such Facilities.

Within 15 business days after the Signing Date, you may appoint up to four additional joint lead arrangers, joint bookrunners agents, co-agents or co-managers (any such arranger, bookrunner, agent, co-agent or co-manager, an “Additional Commitment Party”) or confer other titles in respect of the Facilities in a manner and with economics determined by you (it being understood that to the extent you appoint Additional Commitment Parties or confer other titles in respect of the Facilities, the economics allocated to, and the amount of the commitments of, the Commitment Parties in respect of the Facilities will be reduced ratably by the economics allocated to and the amount of the commitments of such appointed entities upon the execution by such financial institution of customary joinder documentation and, thereafter, each such financial institution shall constitute a “Commitment Party”, “Arranger” and “Initial Lender” hereunder and under the Facilities Fee Letter referred to below; provided that (i) such appointments are made ratably across the Facilities; provided, further, that any Additional Commitment Party may be appointed with a greater than (but not less than) pro rata share of the Revolving Facility, (ii) subject to the proviso in the preceding clause (i), the Initial Lender as of the date hereof shall have not less than 50% of the total economics for each Facility and (iii) no Additional Commitment Party shall have greater economics than any Commitment Party party to this Commitment Letter on the date hereof. Except as provided in this paragraph, no other titles will be awarded and no compensation (other than that expressly contemplated by this Commitment Letter and the Fee Letters referred to below) will be paid to any lender in order to obtain its commitment to participate in any of the Facilities and the Facilities Documentation unless you and the Commitment Parties shall so agree.

2.Fees.

As consideration for the Commitment Parties’ commitments hereunder and their agreements to arrange the Facilities, you agree to pay (or cause to be paid) the nonrefundable fees as set forth in (i) the amended and restated Facilities Fee Letter dated the date hereof between you and us (the “Facilities Fee Letter”) and (ii) the amended and restated Agent Fee Letter dated the date hereof between you and Credit Suisse (the “Agent Fee Letter”, and, together with the Facilities Fee Letter, the “Fee Letters”). All fees shall be fully earned when due and payable in U.S. Dollars in immediately available funds to the applicable Commitment Party. You agree that, once paid, no fees contemplated hereby or under the Fee Letters will be refundable under any circumstances, and all fees payable hereunder or thereunder shall be in addition to any other fees payable pursuant to any other agreement. All fees payable hereunder and under the Fee Letters shall be paid in immediately available funds, free and clear of and without deduction for any and all present or future applicable taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto (with appropriate gross-up for withholding taxes), and shall not be subject to reduction by way of setoff or counterclaim. In connection with the syndication of the Facilities, each Commitment Party may, in its discretion, allocate to the Lenders portions of any fees

payable to such Commitment Party in connection therewith. All fees received by each Commitment Party hereunder or under the Fee Letters may be shared among such Commitment Party and its affiliates as such Commitment Party may determine in its sole discretion.

3.Syndication; Information; Absence of Fiduciary Relationship; Affiliate Activities.

We reserve the right to syndicate all or a portion of the Initial Lenders’ commitments with respect to the Facilities to Lenders identified by us in consultation with you and subject to your prior written consent (such consent not to be unreasonably withheld or delayed). For the avoidance of doubt, the syndication provisions contained in this Section 3 apply to each of the Facilities. Notwithstanding the Arrangers’ right to syndicate the Initial Lenders’ commitments with respect to the Facilities (and receive commitments from the Lenders to such Facilities), it is understood and agreed that except as provided in Section 1 of this Commitment Letter, (i) any syndication of, or receipt of commitments in respect of, all or any portion of an Initial Lender’s commitments hereunder (and your cooperation therewith, including pursuant to this Section 3) prior to the initial funding under such Facilities shall not be a condition to such Initial Lender’s commitments nor reduce such Initial Lender’s commitments hereunder with respect to such Facilities (provided, however, that notwithstanding the foregoing, assignments of an Initial Lender’s commitments, which are effective simultaneously with the funding of such commitments by the assignee, shall be permitted), (ii) notwithstanding any assignment or other transfer by an Initial Lender, no Initial Lender shall be relieved, released or novated from its obligations hereunder in connection with any syndication, assignment or other transfer except in accordance with the Commitment Letter 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, including all rights with respect to consents, modifications and amendments.

We intend to commence syndication efforts promptly after the date hereof, and you agree to assist us in completing a syndication that is reasonably satisfactory to us and you until the earlier to occur of a Successful Syndication (as defined in the Facilities Fee Letter) and 45 days after the Closing Date (such later date, the “Syndication Date”). During such period, such assistance shall include (a) your using commercially reasonable efforts to ensure that any syndication efforts benefit from your existing lending and investment banking relationships, (b) direct contact between appropriate members of senior management, certain representatives and certain non-legal advisors of you and the proposed Lenders, in all such cases at times mutually agreed upon, (c) assistance by you in the preparation of a customary confidential information memorandum (“Customary Information Memorandum”) for each of the Facilities and other customary marketing materials to be used in connection with the syndication of the Facilities, (d) your using commercially reasonable efforts to provide the Arrangers with all additional financial and other information as the Arrangers may reasonably request with respect to the Company, its subsidiaries and the Transactions, (e) your using commercially reasonable efforts to obtain, upon our request, prior to the commencement of general syndication of the Facilities, as applicable, (i) public ratings (but no specific rating) for such Facility and (ii) a public corporate credit rating (but no specific rating) and public corporate family rating (but no specific rating) in respect of the Borrowers, in each case, from each of Standard & Poor’s Ratings Services LLC (“S&P”) and Moody’s Investors Service, Inc. (“Moody’s”), respectively, (f) the hosting, with the Arrangers, of one or more meetings (or, if reasonably acceptable to you and the Arrangers, one or more telephone, video or other electronic conferences) of prospective Lenders at mutually agreed upon times and locations, (g) providing us with copies of all due diligence reports or summaries available to you and prepared in connection with the Transactions by legal, insurance, tax, accounting or other advisors, each subject to the delivery by us to you of customary non-disclosure agreements as shall be reasonably requested and (h) promptly providing us with any other information reasonably requested by us to successfully complete the syndication.

You hereby agree that, prior to the Syndication Date, there shall be no competing issues, offerings or placements of debt securities or commercial bank or other credit facilities by or on behalf of Holdings, you or any of your subsidiaries being offered, placed or arranged (other than the Facilities and other indebtedness incurred in the ordinary course of business of any of you and your subsidiaries for capital expenditures, ordinary course working capital facilities, purchase money and equipment financings and deferred purchase price obligations, Land Newco, Inc.’s incurrence of a $487 mm 364-day bridge loan facility, and any indebtedness permitted to remain outstanding under the Merger Agreement with respect to Land Newco, Inc.), without the consent of the Arrangers, if such issuance, offering, placement or arrangement would reasonably be expected to materially impair the primary syndication of the Facilities.

In addition, you agree to use your commercially reasonably efforts to cause the Arrangers to have been afforded a period of at least 15 consecutive business days (ending no later than the business day immediately prior to the Closing Date) following the date of delivery of (a) Holdings’ audited consolidated balance sheet and consolidated statements of operations, comprehensive income, stockholder’s equity and cash flows for the three most recent fiscal years ended at least 60 days prior to the Closing Date and the unaudited consolidated balance sheet and consolidated statements of operations, comprehensive income, stockholder’s equity and cash flows for the most recent fiscal quarters ended at least 45 days prior to the Closing Date and (b) the financial statements referred to in paragraph 4 of Annex C, together with the Customary Information Memorandum in connection with the syndication of each of the Facilities (together, the “Required Bank Information”) to market each of the Facilities to prospective Lenders (the “Bank Marketing Period”); provided that (i) the Bank Marketing Period shall exclude November 26, 2021 (it being understood that such days shall be disregarded for purposes of calculating the consecutive business days constituting the Bank Marketing Period) and (ii) if the Bank Marketing Period has not concluded prior to (A) August 20, 2021, it shall commence no earlier than September 7, 2021 and (B) December 17, 2021, it shall commence no earlier than January 3, 2022.

The Arrangers will manage all aspects of any syndication in consultation with you, including (in each case subject to the provisions set forth in this Commitment Letter), decisions as to the selection of institutions to be approached and when they will be approached, when their commitments will be accepted, which institutions will participate, the allocation of the commitments among the Lenders, any naming rights and the amount and distribution of fees among the Lenders. To assist the Arrangers in their syndication efforts, you agree promptly to prepare and provide to the Arrangers all customary information reasonably requested by the Arrangers that is reasonably available to you with respect to the Company and its subsidiaries, and the Transactions as the Arrangers may reasonably request in connection with the structuring, arrangement and syndication of the Facilities.

You agree, at the request of the Arrangers, to assist in the preparation of a version of any marketing and informational materials and presentations that may be used in connection with the Facilities that will consist exclusively of information and documentation that is either (i) publicly available or (ii) not material with respect to Holdings or its parents or subsidiaries taken as a whole, or any of their respective securities for purposes of United States Federal, foreign and state securities laws (all such information and documentation being “Public Lender Information”). Any information and documentation that is not Public Lender Information is referred to herein as “Private Lender Information.” You further agree that each document to be disseminated by the Arrangers to any Lender in connection with syndicating the Facilities will, at the request of the Arrangers, be identified by you as either (i) containing Private Lender Information or (ii) containing solely Public Lender Information. You acknowledge that the following documents contain solely Public Lender Information (unless you notify us promptly prior to their intended distribution (provided that you have been given a reasonable opportunity to review such documents in advance of their intended distribution) that any such document

contains Private Lender Information): (a) drafts and final definitive documentation with respect to the Facilities; (b) administrative materials prepared by the Arrangers or the Agent for Lenders (such as a lender meeting invitation); and (c) notification of changes in the terms of the Facilities. It is understood that, in connection with your assistance described above, customary authorization letters will be included in any information package and presentation whereby you authorize the distribution of such information to prospective Lenders containing a representation substantially consistent with the first sentence of the succeeding paragraph and a representation by you to the Commitment Parties that the Public Lender Information does not include material non-public information about Holdings and its subsidiaries, taken as a whole, or their securities and exculpating us with respect to any liability related to the use of the contents of such Public Lender Information or any related marketing material by the recipients thereof.

You hereby represent and covenant that (a) all information (the “Information”) other than the Projections (defined below) that has been or will be provided by or on behalf of you or any of your representatives to us is or will be, when taken as a whole, complete and correct in all material respects and does not or will not, when taken as a whole, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein not materially misleading in light of the circumstances under which such statements are made and (b) any projections (the “Projections”) that have been or will be provided by or on behalf of you or any of your representatives to us have been or will be prepared in good faith based upon accounting principles consistent with your historical audited financial statements and upon assumptions that are reasonable at the time made and at the time the related Projections are made available to us. You agree that if at any time prior to the later of the Closing Date and the Syndication Date, any of the representations in the preceding sentence would be materially incorrect if the Information and Projections were being furnished, and such representations were being made, at such time, then you will promptly supplement the Information and the Projections so that such representations will be correct under those circumstances, with such supplementation deemed to cure any such inaccuracy. In arranging the Facilities, we will be entitled to use and rely primarily on the Information and Projections without responsibility for independent verification thereof.

We will not furnish Information or Projections obtained from you by virtue of the transactions contemplated by this Commitment Letter or our other relationships with you to other companies. You also acknowledge that we do not have any obligation to use in connection with the transactions contemplated by this Commitment Letter, or to furnish to you, confidential information obtained by us from other companies.

You further acknowledge and agree that (a) no fiduciary, advisory or agency relationship between you and us is intended to be or has been created in respect of any of the transactions contemplated by this Commitment Letter, irrespective of whether we have advised or are advising you on other matters, (b) the Commitment Parties, on the one hand, and you, on the other hand, have an arm’s-length business relationship that does not directly or indirectly give rise to, nor do you rely on, any fiduciary duty on the part of us, (c) you are capable of evaluating and understanding, and you understand and accept, the terms, risks and conditions of the transactions contemplated by this Commitment Letter, (d) you have been advised that we are engaged in a broad range of transactions that may involve interests that differ from your interests and that we have no obligation to disclose such interests and transactions to you by virtue of any fiduciary, advisory or agency relationship, and (e) you waive, to the fullest extent permitted by law, any claims you may have arising out of or in connection with the transactions contemplated by this Commitment Letter against us for breach of fiduciary duty or alleged breach of fiduciary duty and agree that we shall have no liability (whether direct or indirect) to you in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of you, including your stockholders, employees or creditors.

In particular, you acknowledge that CS Securities (USA) LLC (“CS Securities”), an affiliate of CS and CSLF, is acting as a financial advisor (the “Financial Advisor”) to you in connection with the Transactions. You agree not to assert or allege any claim based on actual or potential conflict of interest arising or resulting from, on the one hand, the engagement of CS Securities in such capacity and our obligations hereunder, on the other hand. Each of the Additional Commitment Parties hereto acknowledges (i) the retention of CS Securities as the Financial Advisor and (ii) that such relationship does not create any fiduciary duties or fiduciary responsibilities to such Additional Commitment Party on the part of CS, CSLF or any of their affiliates.

You further acknowledge that certain of the Commitment Parties and/or certain of their respective affiliates currently may be acting as lenders under the Existing Credit Agreement, and your and your subsidiaries’ rights and obligations under any other agreement with any Commitment Party or any of its affiliates (including the Existing Credit Agreement) that currently exist or hereafter may exist are, and shall be, separate and distinct from the rights and obligations of the parties pursuant to this Commitment Letter, and none of such rights and obligations under such other agreements shall be affected by any Commitment Party’s performance or lack of performance of services hereunder. You hereby agree that each Commitment Party may render its services under this Commitment Letter notwithstanding any actual or potential conflict of interest presented by the foregoing, and you agree that you will not claim any conflict of interest relating to the relationship among any Commitment Party and you and your affiliates in connection with the services contemplated hereby, on the one hand, and the exercise by such Commitment Party or any of its affiliates of any of their rights and duties under any credit agreement or other agreement (including the Existing Credit Agreement) on the other hand.

You further acknowledge that each of us is a full service securities firm engaged in securities trading and brokerage activities as well as providing investment banking and other financial services. In the ordinary course of business, we may provide investment banking and other financial services to, and/or acquire, hold or sell, for our own accounts and the accounts of customers, equity, debt and other securities and financial instruments (including bank loans and other obligations) of you and other companies with which you may have commercial or other relationships. With respect to any securities and/or financial instruments so held by us or any of our customers, all rights in respect of such securities and financial instruments, including any voting rights, will be exercised by the holder of the rights, in its sole discretion. Additionally, you acknowledge and agree that none of us or our affiliates are advising you as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction (including, without limitation, any consents needed in connection with the transactions contemplated hereby). You shall consult with your own advisors concerning such matters and shall be responsible for making your own independent investigation and appraisal of the transactions contemplated hereby (including, without limitation, any consents needed in connection therewith), and we shall have no responsibility or liability to you with respect thereto.

Notwithstanding anything herein to the contrary, none of (a) the commencement nor the completion of the syndication of the Facilities, (b) the obtaining of the ratings referred to in the second paragraph of this Section 3, (c) compliance with any of the other provisions set forth in this Section 3 nor (d) the accuracy of any representations or warranties made in the information representation and warranty in this Section 3, shall constitute a condition precedent to the availability and initial funding of the Facilities on the Closing Date.

The commitments of each Commitment Party hereunder and its agreement to perform the services described herein in respect of each of the Facilities are subject only to (in each case, such condition which relates to the corresponding Facility only) the execution of the definitive documentation with respect to such Facility in accordance with the Documentation Principles (as defined below) and the satisfaction (or waiver) of the conditions precedent set forth in Annex C (the “Funding Conditions”); it being understood that there are no conditions (implied or otherwise) to the commitments hereunder (including compliance with the terms of this Commitment Letter, the Fee Letters and the Facilities Documentation) other than the Funding Conditions that are expressly stated to be conditions to the initial funding under the Facilities on the Closing Date (and upon satisfaction or waiver of such conditions, the initial funding under the Facilities shall occur).

Notwithstanding anything to the contrary in this Commitment Letter (including each of the annexes attached hereto), the Fee Letters, the Facilities Documentation or any other letter agreement or other undertaking concerning the financing of the Transactions, (i) the only representations and warranties the accuracy of which shall be a condition to availability and the initial funding of the Facilities on the Closing Date shall be the Specified Representations (as defined below) made by the Borrowers and the domestic Guarantors in the Facilities Documentation and (ii) the terms of the Facilities Documentation shall be in a form such that they do not impair the availability of the Facilities on the Closing Date if the Funding Conditions are satisfied (it being understood that to the extent any Collateral (other than assets of Holdings, the Borrowers and the Guarantors with respect to which a lien may be perfected solely by the filing of a financing statement under the Uniform Commercial Code and the delivery of stock certificates of the Borrowers and material (to be defined in a manner to be agreed) wholly-owned domestic restricted subsidiaries of the Borrowers) is not or cannot be provided or perfected on the Closing Date after your use of commercially reasonable efforts to do so or without undue burden or expense, the provision and/or perfection of such Collateral shall not constitute a condition precedent to the availability of the Facilities on the Closing Date, but shall be required to be provided and/or perfected within 90 days after the Closing Date (in each case, subject to extensions as agreed by the Agent in its reasonable discretion)). For purposes hereof, “Specified Representations” means the representations and warranties of the Borrowers and the Guarantors (after giving effect to the Transactions) set forth in the Facilities Documentation relating to corporate or other organizational existence of the Borrowers and the Guarantors; organizational power and authority of the Borrowers and Guarantors (as to execution, delivery and performance of the applicable Facilities Documentation); the due authorization, execution and delivery by the Borrowers and the Guarantors of the applicable Facilities Documentation; enforceability of the applicable Facilities Documentation against the Borrowers and Guarantors; Federal Reserve margin regulations; the Investment Company Act; the creation, validity and perfection of security interests in the Collateral (subject to permitted liens and the limitations set forth in the preceding sentence); no conflicts of the applicable Facilities Documentation (limited to the execution, delivery and performance of the Facilities Documentation, incurrence of the indebtedness thereunder and the granting of the guarantees and the security interests in respect thereof) with charter documents of the Borrowers or any Guarantor; solvency as of the Closing Date (after giving effect to the Transactions) of the Borrowers and their respective subsidiaries on a consolidated basis (to be determined in a manner consistent with the solvency certificate to be delivered in the form set forth in Annex C-I attached to Exhibit C); PATRIOT Act (as defined below); and use of the proceeds of the Facilities not violating FCPA, OFAC and other anti-terrorism laws.

This Section 4 in its entirety shall be referred to herein as the “Limited Conditionality Provision”.

5.Documentation.

It is acknowledged and agreed by the parties to this Commitment Letter that (i) it is their intention that they will negotiate in good faith the definitive documentation with respect to each of the Facilities (collectively, the “Facilities Documentation”) to reflect the provisions set out in this Commitment Letter as soon as reasonably practicable following the date on which you countersign this Commitment Letter (the “Countersign Date”) and (ii) the Commitment Parties will cooperate with you as reasonably requested in coordinating the timing and procedures for the funding of the Facilities in a manner consistent with the Merger Agreement.

The Facilities Documentation will be based upon, and be substantially identical to, the Existing Credit Agreement (as modified and updated to reflect the terms contained in Annex B and the exercise of any “flex”’ provisions of the Facilities Fee Letter); provided, further, that such documentation will also include customary changes and updates to reflect (i) the Agent’s reasonable operational and agency guidelines and practices and (ii) changes in law and accounting since the date of the Existing Credit Agreement (including customary provisions addressing LIBOR replacement, capital leases and post-Brexit EU/UK “bail-in” provisions). This paragraph is referred to as the “Documentation Principles”.

6.Jurisdiction.

Each of the parties hereto hereby irrevocably and unconditionally (a) submits, for itself and its property, to the exclusive jurisdiction of any New York State court or Federal court of the United States of America sitting in the Borough of Manhattan in New York City, and any appellate court from any thereof, in any suit, action or proceeding arising out of or relating to this Commitment Letter, the Fee Letters or the Transactions and the other transactions contemplated hereby, and agrees that all claims in respect of any such suit, action or proceeding shall be heard and determined only in such New York State court or, to the extent permitted by law, in such Federal court, provided that suit for the recognition or enforcement of any judgment obtained in any such New York State or Federal court may be brought in any other court of competent jurisdiction, (b) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Commitment Letter, the Fee Letters or Transactions and the other the transactions contemplated hereby in any New York State court or in any such Federal court, (c) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court and (d) agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Service of any process, summons, notice or document by registered mail addressed to you at the address above shall be effective service of process against you for any suit, action or proceeding brought in any such court.

7.Waiver of Jury Trial.

8.General.

You agree (a) to indemnify and hold harmless each Commitment Party and its affiliates and their respective officers, directors, employees, agents, advisors, controlling persons, members and successors and assigns (each, an “Indemnified Person”) from and against any and all losses, claims, damages, liabilities and expenses, joint or several, to which any such Indemnified Person may become subject arising out of or in connection with this Commitment Letter, the Fee Letters, the Transactions or any related transaction or any claim, litigation, investigation or proceeding relating to any of the foregoing, regardless of whether any such Indemnified Person is a party thereto (and regardless of whether such matter is initiated by a third party or by the Company or any of its affiliates), and to reimburse each such Indemnified Person upon demand for any reasonable and documented legal or other expenses incurred in connection with investigating, defending or enforcing any of the foregoing, provided that the foregoing indemnity will not, as to any Indemnified Person, apply to losses, claims, damages, liabilities or related expenses to the extent they are found in a final, non-appealable judgment of a court of competent jurisdiction to have resulted from the willful misconduct or gross negligence of such Indemnified Person, and (b) to reimburse the Commitment Parties from time to time, upon presentation of a summary statement, for all reasonable and documented out-of-pocket expenses, in each case, incurred in connection with the Transactions and the transactions contemplated thereby and the preparation and negotiation of this Commitment Letter, the Fee Letters, the Facilities Documentation and any ancillary documents in connection therewith (including the cost of outside counsel). Notwithstanding any other provision of this Commitment Letter, no Indemnified Person shall be liable for any indirect, special, punitive or consequential damages in connection with its activities related to the Transactions.

This Commitment Letter shall not be assignable by any party hereto without the prior written consent of the other parties hereto (and any attempted assignment without such consent shall be null and void), is intended to be solely for the benefit of the parties hereto (and Indemnified Persons), and is not intended to confer any benefits upon, or create any rights in favor of, any person other than the parties hereto (and Indemnified Persons). Any and all services to be provided by each of us hereunder may be performed and any and all of our rights hereunder may be exercised by or through any of its affiliates or branches and, in connection with the provision of such services, such persons may exchange with each other information concerning you and the other companies that may be the subject of the transactions contemplated by this Commitment Letter and, to the extent so employed, such affiliates and branches shall be entitled to the benefits afforded to us hereunder.

This Commitment Letter may not be amended or any provision hereof waived or modified except by an agreement in writing signed by each of the parties hereto. THIS COMMITMENT LETTER, THE FEE LETTERS AND ANY CLAIM, CONTROVERSY OR DISPUTE (INCLUDING, WITHOUT LIMITATION, ANY CLAIMS SOUNDING IN CONTRACT LAW OR TORT LAW ARISING OUT OF THE SUBJECT MATTER HEREOF) ARISING UNDER OR RELATED TO THIS COMMITMENT LETTER OR THE FEE LETTERS SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. This Commitment Letter may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Any signature to this Commitment Letter may be delivered by electronic mail (including pdf) or any electronic signature complying with the U.S. federal ESIGN Act of 2000 or the New York Electronic Signature and Records Act or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes to the fullest extent permitted by applicable law. For the avoidance of doubt, the foregoing also applies to any amendment, extension or renewal of this Commitment Letter.

We may place advertisements in financial and other newspapers and periodicals or on a home page or similar place for dissemination of information on the

Internet or worldwide web as it may choose, and circulate similar promotional materials, after the closing of the Transactions in the form of a “tombstone” or otherwise describing the names of the Company and its affiliates (or any of them, but excluding Land Newco, Inc. and its subsidiaries), and the amount, type and closing date of the transactions contemplated hereby, all at the expense of the applicable Commitment Party.

This Commitment Letter and the Fee Letters shall become effective upon execution and delivery by all parties hereto and thereto, respectively. The commitment of the Initial Lender to extend credit, any undertaking of CS as administrative agent and collateral agent with respect to the Facilities, and the agreement of any Arranger to perform any services hereunder shall terminate upon the earliest to occur of: (a) the consummation of the Merger and the Refinancing without the funding of the Facilities (but without excusing any breach of this Commitment Letter if any of the Commitment Parties refuse to fund any of the Facilities); (b) upon the End Date (as defined in the Merger Agreement as in effect on the Signing Date, including any extension of the End Date permitted under the Merger Agreement) plus five (5) business days; and (c) with respect to each Facility, our receipt of written notice from you terminating the commitments under such Facility in full.

The Original Commitment Letter shall be superseded hereby in its entirety upon the effectiveness of this Commitment Letter; provided that, notwithstanding anything to the contrary herein, Credit Suisse shall be entitled to the benefits of the indemnification and expense reimbursement provisions of this Commitment Letter as if they were in effect on the Signing Date.

The undersigned hereby certifies, solely in his capacity as an officer of the Borrowers and not in his individual capacity, as follows:

1.I am the [Financial Officer] of the Borrowers. I am familiar with the Transactions, and have reviewed the Credit Agreement, financial statements referred to in Section [___] of the Credit Agreement and such documents and made such investigation as I have deemed relevant for the purposes of this Solvency Certificate.

2.As of the date hereof, immediately after giving effect to the consummation of the Transactions, on and as of such date (i) the fair value of the assets of the Borrowers and their Subsidiaries on a consolidated basis, at a fair valuation, exceeds the debts and liabilities, direct, subordinated, contingent or otherwise, of the Borrowers and their Subsidiaries on a consolidated basis; (ii) the present fair saleable value of the property of the Borrowers and their Subsidiaries on a consolidated basis is greater than the amount that will be required to pay the probable liability of the Borrowers and their Subsidiaries on a consolidated basis on their debts and other liabilities, direct, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured; (iii) the Borrowers and their Subsidiaries on a consolidated basis are able to pay their debts and liabilities, direct, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured; and (iv) the Borrowers and their Subsidiaries on a consolidated basis do not have unreasonably small capital with which to conduct the businesses in which they are engaged as such businesses are now conducted and are proposed to be conducted following the Closing Date.

3.As of the date hereof, immediately after giving effect to the consummation of the Transactions, the Borrowers do not intend to, and the Borrowers do not believe that they or any of their Subsidiaries will, incur debts beyond their ability to pay such debts as they mature, taking into account the timing and amounts of cash to be received by it or any such Subsidiary and the timing and amounts of cash to be payable on or in respect of its Indebtedness or the Indebtedness of any such Subsidiary.

This Solvency Certificate is being delivered by the undersigned officer only in his capacity as [Financial Officer] of the Borrowers and not individually and the undersigned shall have no personal liability to the Administrative Agent or the Lenders with respect thereto.

IN WITNESS WHEREOF, the undersigned has executed this Solvency Certificate on the date first written above.
