Re: Monitoring Agreement

Ladies and Gentlemen:

This letter serves to confirm that Brickman Acquisition Holdings, Inc. (f/k/a Garden Acquisition Holdings, Inc.) (the “Company”) has engaged Kohlberg Kravis Roberts & Co. L.P. (“KKR”) and MSD Capital, L.P. (“MSD”) (together, the “Managers”) to provide, and the Managers hereby agree to provide, management, consulting and financial services to the Company and its direct and indirect divisions, subsidiaries, parent entities and controlled affiliates (collectively, the “Company Group”), as follows:

1. The Company has engaged the Managers, and each of the Managers hereby agrees to accept such engagement, to provide to the Company Group, when and if called upon, such services as mutually agreed by the Managers and the Company, which services may include, without limitation: (i) general executive and management services; (ii) identification, support, negotiation and analysis of acquisitions and dispositions by the Company Group; (iii) support, negotiation and analysis of financing alternatives, including, without limitation, in connection with acquisitions, capital expenditures and refinancing of existing indebtedness; (iv) finance functions, including assistance in the preparation of financial projections and monitoring of compliance with financing agreements; (v) human resources functions, including searching and recruiting of executives, but excluding formulation or promulgation of personnel policies or involvement in personnel decision making; and (vi) other services for the Company Group upon which the Company and each of the Managers may agree from time to time. Commencing on the date of the Merger (as defined in the first sentence of Section 11), the Company agrees to pay to the Managers (or such affiliate(s) as the Managers may designate) an aggregate annual fee (the “Advisory Fee”) in an amount equal to 1.00% of Adjusted EBITDA (as defined in The Brickman Group Ltd. LLC’s First Lien Credit Agreement, dated as of December 18, 2013) calculated based on the prior fiscal year’s Adjusted EBITDA, payable in quarterly installments in arrears at the end of each fiscal quarter. KKR shall be entitled to 77.5% of the Advisory Fee and MSD shall be entitled to 22.5% of the Advisory Fee, and the Company shall pay to each of KKR and MSD its portion of the Advisory Fee in accordance with the terms hereof. Within ninety days (or such longer period of time reasonably required) after the end of each fiscal year (commencing with the first fiscal year ending after the date of this agreement), the Company

shall certify the Adjusted EBITDA for the preceding fiscal year to the Managers. The initial Advisory Fee payable to each Manager shall be prorated to reflect the portion of the current fiscal quarter that will elapse after the Effective Date. The final quarterly Advisory Fee payable to each Manager shall be prorated to reflect the portion of the final quarter prior to the end of the term of this agreement, as applicable.

2. From time to time the Managers may charge the Company a customary fee (a “Transaction Fee”) for services rendered in connection with structuring and negotiating an acquisition, divestiture, recapitalization or similar transaction by or involving the Company Group. 77.5% of any Transaction Fee charged to the Company shall be charged by and payable to KKR or such affiliate(s) of KKR as KKR may designate, and 22.5% of any such fee shall be charged by and payable to MSD or such affiliate(s) of MSD as MSD may designate. From time to time an affiliate of KKR may charge the Company a customary fee (a “Capital Markets Fee”) for services rendered in the capacity of an underwriter, syndicator, placement agent, manager or in a similar role in connection with equity or debt financing or syndication transactions, including in connection with any acquisition, divestiture, initial public offering or other transaction (including the acquisition of ValleyCrest and its affiliates), in each case, by or involving the Company Group. 100% of any Capital Markets Fee charged to the Company shall be payable to KKR or such affiliate(s) of KKR as KKR may designate. The arrangements may at the discretion of the Company be reflected in separate agreements between the Company and the Managers (in connection with the Transaction Fee) or KKR or its affiliates (in connection with the Capital Markets Fee). In addition to any fees that may be payable to the Managers under this agreement, the Company shall, or shall cause one or more of its affiliates to, on behalf of itself and the other members of the Company Group (subject to paragraph 3), reimburse the Managers and their affiliates and their employees and agents, from time to time upon request, for all reasonable out-of-pocket expenses incurred, including unreimbursed out-of-pocket expenses incurred to the date hereof, in connection with this retention, including travel expenses and expenses of any legal, accounting or other professional advisors to the Managers or their affiliates. The Managers may submit monthly expense statements to the Company or any other member of the Company Group for such out-of-pocket expenses, which statements shall be payable within thirty days, other than with respect to expenses of MSD, ValleyCrest Holding Co. or any of their affiliates relating to the period prior to the closing of the Merger (as defined below).

3. The Company (on behalf of itself and the other members of the Company Group) hereby acknowledges and agrees that the obligations of the Company under paragraphs 1 and 2 shall be borne jointly and severally by each member of the Company Group.

4. The Company will, and will cause each member of the Company Group to, use its reasonable best efforts to furnish, or to cause their respective subsidiaries and agents to furnish, the Managers with such information (the “Information”) as the Managers reasonably believe appropriate to their engagement hereunder, provided that the Company shall not be obligated to provide Information to MSD except to the extent required pursuant to Section 3.4(a) of the Partnership Agreement (as defined below). The Company acknowledges and agrees that (i) the Managers will rely on the Information and on information available from generally recognized public sources in performing the services contemplated hereunder and (ii) the Managers do not assume responsibility for the accuracy or completeness of the Information or such other information.

6. Any advice or opinions provided by a Manager may not be disclosed or referred to publicly or to any third party (other than the Company Group’s legal, tax, financial or other advisors), except with the prior written consent of such Manager.

Without limiting the generality of the foregoing, the parties acknowledge that nothing in this agreement, expressed or implied, is intended to confer on any present or future holders of any securities of the Company or its subsidiaries or affiliates, or any present or future creditor of the Company or its subsidiaries or affiliates, any rights or remedies under or by reason of this agreement or any performance hereunder.

LLC, a Delaware limited liability company, Blade Merger Sub, Inc., a Delaware corporation, ValleyCrest Holding Co., a Delaware corporation, and MSD Valley Investments, LLC, solely in its capacity as the initial Holder Representative; if the Merger Agreement terminates without the occurrence of the Merger, this agreement shall not become effective. This agreement shall continue in effect from year to year unless amended or terminated by the consent of the Company and KKR; provided, that (i) the Company shall provide MSD prompt written notice of any such termination or amendment; (ii) in the event of a termination, the Company and its parent entities and subsidiaries shall not enter into another agreement with KKR or its affiliates covering services similar to the ones covered by this Agreement without making MSD a party to such agreement on the same terms as contained in this Agreement (this sentence shall survive any such termination) and (iii) in the event of an amendment, such amendment applies equally to both Managers and does not change this sentence. KKR may waive any of the rights of the Managers under this Agreement (other than this Section 11), and such waiver shall be effective with respect to both Managers provided that such waiver applies equally to both Managers. In addition, the Company may terminate this agreement by delivery of a written notice of termination to each of the Managers at any time after the Managers and their affiliates no longer hold any equity interests in the Company; provided that in the event of such a termination the Company shall pay in cash to each of the Managers all unpaid Advisory Fees payable to the Managers in accordance with Section 1 and all expenses due under this agreement to each of the Managers with respect to periods prior to the termination date. In addition, (i) in connection with the consummation of a Change of Control (as defined in the Second Amended and Restated Limited Partnership Agreement, dated as of the date of the Merger, among the parties thereto, (as the same may be amended from time to time the “Partnership Agreement”), the Company may terminate this agreement by delivery of a written notice of termination to each of the Managers and (ii) immediately following the consummation of an Initial Public Offering (as defined in the Partnership Agreement), this agreement shall automatically terminate unless the Company, by delivery of a written notice to each of the Managers prior to such consummation, otherwise elects to continue this agreement in full force and effect.
