5. Escrow Agent. The Escrow Agent undertakes to perform only such duties as are expressly set forth herein, which shall be deemed purely ministerial in nature, and no duties, including but not limited to any fiduciary duties, shall be implied. The Escrow Agent shall neither be responsible for, nor chargeable with, knowledge of, nor have any requirements to

comply with, the terms and conditions of any other agreement, instrument or document between the Parties, in connection herewith, if any, including without limitation the Merger Agreement, nor shall the Escrow Agent be required to determine if any Person has complied with any such agreements, nor shall any additional obligations of the Escrow Agent be inferred from the terms of such agreements, even though reference thereto may be made in this Agreement. Notwithstanding the terms of any other agreement between the Parties, the terms and conditions of this Agreement will control the actions of Escrow Agent. The Escrow Agent may rely upon and shall not be liable for acting or refraining from acting upon any Joint Release Instruction or Final Determination furnished to it hereunder and reasonably believed by it in good faith to be genuine and to have been signed and presented by an authorized signer of the proper Party or Parties. Concurrent with the execution of this Agreement, the Parties shall deliver to the Escrow Agent authorized signers’ forms in the form of Exhibit A-1, Exhibit A-2 and Exhibit A-3 attached hereto. The Escrow Agent shall be under no duty to inquire into or investigate the validity, accuracy or content of any such document, notice, instruction or request. The Escrow Agent shall have no duty to solicit any payments which may be due it or the Escrow Funds. In the event that the Escrow Agent shall be uncertain as to its duties or rights hereunder or shall receive instructions, claims or demands from any Party hereto which, in its opinion, conflict with any of the provisions of this Agreement, it shall be entitled to refrain from taking any action and its sole obligation shall be to keep safely all property held in escrow until it shall be directed otherwise in a Joint Release Instruction or Final Determination. The Escrow Agent may interplead all of the assets held hereunder into a court of competent jurisdiction or may seek a declaratory judgment with respect to certain circumstances, and thereafter be fully relieved from any and all liability or obligation with respect to such interpleaded assets or any action or nonaction based on such declaratory judgment. The Escrow Agent may consult with legal counsel of its selection in the event of any dispute or question as to the meaning or construction of any of the provisions hereof or its duties hereunder. The Escrow Agent will not be liable for any action taken, suffered or omitted to be taken by it in good faith except to the extent that the Escrow Agent’s gross negligence or willful misconduct was the cause of any direct loss to either Party. To the extent practicable, the Parties agree to pursue any redress or recourse in connection with any dispute without making the Escrow Agent a party to the same. Anything in this Agreement to the contrary notwithstanding, in no event shall the Escrow Agent be liable for any special, indirect, punitive, incidental or consequential losses or damages of any kind whatsoever (including but not limited to lost profits), even if the Escrow Agent has been advised of the likelihood of such losses or damages and regardless of the form of action.

6. Resignation and Removal of Escrow Agent. The Escrow Agent (a) may resign and be discharged from its duties or obligations hereunder by giving thirty (30) calendar days advance notice in writing of such resignation to the Parties specifying a date when such resignation shall take effect or (b) may be removed, with or without cause, by Landscape and the Company Partners’ Representative acting jointly at any time by providing written notice to the Escrow Agent. Any corporation or association into which the Escrow Agent may be merged or converted or with which it may be consolidated, or any corporation or association to which all or substantially all of the escrow business of the Escrow Agent’s line of business may be transferred, shall be the Escrow Agent under this Agreement without further act. The Escrow Agent’s sole responsibility after such thirty (30) day notice period expires or after receipt of written notice of removal shall be to hold and safeguard the Escrow Funds (without any

obligation to reinvest the same) and to deliver the same (i) to a substitute or successor escrow agent pursuant to a joint written designation from the Parties, (ii) as set forth in a Joint Release Instruction or (iii) in accordance with the directions of a Final Determination, and, at the time of such delivery, the Escrow Agent’s obligations hereunder shall cease and terminate. In the event the Escrow Agent resigns, if the Parties have failed to appoint a successor escrow agent prior to the expiration of thirty (30) calendar days following receipt of the notice of resignation, the Escrow Agent may petition any court of competent jurisdiction for the appointment of such a successor escrow agent or for other appropriate relief, and any such resulting appointment shall be binding upon all of the parties hereto.

7. Fees and Expenses. All fees and expenses of the Escrow Agent are described in Schedule 1 attached hereto and shall be paid by Landscape and the Company, jointly and/or severally. The fees agreed upon for the services to be rendered hereunder are intended as full compensation for the Escrow Agent services as contemplated by this Agreement.

8. Indemnity. Each of the Parties shall jointly and severally indemnify, defend, and hold harmless the Escrow Agent and its affiliates and their respective successors, assigns, directors, officers, agents and employees (the “Indemnitees”) from and against any and all losses, damages, claims, liabilities, penalties, judgments, settlements, actions, suits, proceedings, litigation, investigations, costs or expenses (including the reasonable and documented out-of-pocket fees and expenses of one outside counsel and experts and their staffs and all reasonable and documented expense of document location, duplication and shipment) (collectively “Escrow Agent Losses”) arising out of or in connection with (a) the Escrow Agent’s performance of this Agreement, tax reporting or withholding or the enforcement of any rights or remedies under or in connection with this Agreement, except to the extent that such Escrow Agent Losses are determined by a court of competent jurisdiction through a final order to have been caused by the fraud, gross negligence or willful misconduct of such Indemnitee, or (b) its following any instructions or other directions from Landscape or the Company Partners’ Representative. The Parties hereby grant the Escrow Agent a lien on, right of set-off against and security interest in, the Escrow Funds for the payment of any reasonable claim for indemnification, expenses and amounts due hereunder. In furtherance of the foregoing, the Escrow Agent is expressly authorized and directed, but shall not be obligated, upon prior written notice to the Parties, to charge against and withdraw from the Escrow Funds for its own account or for the account of an indemnitee any amounts due to the Escrow Agent or to an indemnitee under this Section 8. Notwithstanding anything to the contrary herein, Landscape and the Company Partners’ Representative agree, solely as between themselves, that any obligation for indemnification under this Section 8 (or for reasonable and documented fees and expenses of the Escrow Agent described in Section 7) shall be borne by the Party or Parties determined by a court of competent jurisdiction to be responsible for causing the loss, damage, liability, cost or expense against which the Escrow Agent is entitled to indemnification or, if no such determination is made, then one-half by Landscape and one-half by the Company Partners’ Representative. The Parties acknowledge that the foregoing indemnities shall survive the resignation or removal of the Escrow Agent or the termination of this Agreement.

9. Tax Matters.

(a) Landscape shall be responsible for and the taxpayer on all taxes due on the interest or income earned, if any, on the Escrow Funds for the calendar year in which such interest or income is earned.

Prior to the Closing Date, the Parties shall provide the Escrow Agent with certified tax identification numbers by furnishing appropriate forms W-9 or W-8 as applicable and such other forms and documents that the Escrow Agent may reasonably request.

(b) The Escrow Agent shall be responsible only for income reporting to the Internal Revenue Service with respect to income earned on the Escrow Funds. The Escrow Agent shall withhold any taxes required to be withheld by applicable law, including but not limited to required withholding in the absence of proper tax documentation, and shall remit such taxes to the appropriate authorities; provided that, to the extent possible, prior to withholding any such taxes, the Escrow Agent shall notify the Parties that such taxes are required to be withheld by applicable law and shall reasonably cooperate with the Parties to reduce or eliminate the amount of such taxes required to be withheld.

(c) The Escrow Agent, its affiliates, and its employees are not in the business of providing tax or legal advice to any taxpayer outside of Citigroup, Inc. and its affiliates. This Agreement and any amendments or attachments hereto are not intended or written to be used, and may not be used or relied upon, by any such taxpayer or for the purpose of avoiding tax penalties. Any such taxpayer should seek advice based on the taxpayer’s particular circumstances from an independent tax advisor.

13. Miscellaneous. The provisions of this Agreement may be waived, altered, amended or supplemented, in whole or in part, only by a writing signed by all of the parties hereto. Neither this Agreement nor any right or interest hereunder may be assigned in whole or

Except as expressly provided in Sections 7 and 8, nothing in this Agreement, whether express or implied, shall be construed to give to any person or entity other than the Escrow Agent and the Parties any legal or equitable right, remedy, interest or claim under or in respect of this Agreement or any funds escrowed hereunder.

Any transfer or assignment of the rights, interests or obligations hereunder in violation of the terms hereof shall be void and of no force or effect.

17. Force Majeure. The Escrow Agent shall not incur any liability for not performing any act or fulfilling any obligation hereunder by reason of any occurrence beyond its control (including, but not limited to, any provision of any present or future law or regulation or any act of any governmental authority, any act of God or war or terrorism, or the unavailability of the Federal Reserve Bank wire services or any electronic communication facility), it being understood that the Escrow Agent shall use commercially reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as reasonably practicable under the circumstances.

18. Compliance with Federal Law.
