Such cooperation shall include, if the same would result in a material diminution of such charges over the term of such lease, segregating, at Purchaser’s sole cost and expense, the unused portion of the Purchaser’s leased premises so as to reduce the space to which utilities and services are provided. No such reduction or elimination of utilities or services or segregation will be permitted to the extent that it is not in compliance with laws (it being understood, however, that, in the absence of any order of a Government Entity requiring the same, Purchaser shall have no obligation to effect such segregation by erection of a code-compliant demising wall), imposes any health or safety risk to any person, or impairs, in any material respect, the use, operation or value of the site, including for sale or lease to third parties (but taking into account Purchaser’s obligation to restore such segregation at the end of the term of the Direct Lease).

20. Initial Payment of Rent, License and Service Fees and Security Deposits. The Parties agree that (notwithstanding any provision of any Sublease, Direct Lease, assignment agreement, license agreement or services agreement to the contrary), not later than thirty (30) days after the Closing Date (or the first Business Day thereafter if such date is not a Business Day), (i) the Purchaser shall be entitled to pay the rent, additional rent, license fees and services fees due under each Sublease, Direct Lease, license agreement and services agreement for the months of December, 2009 and January, 2010 and to post all security deposits required thereunder (whether in cash or by letter of credit) and (ii) the Parties shall, with respect to all Designated 365 Real Estate Leases and Designated Non-365 Real Estate Leases and the Owned Real Estate, make payments or settlements in respect of any rent, additional rent and other pre-paid expenses (with such rent, additional rent and other expenses to be apportioned between the Parties as of the Closing Date); provided that interest shall accrue and be payable on all such payments not made on or before January 1, 2010 from such date until the date payment is made at three percent (3%) per annum and provided further that, to the extent any such payment is not made by the date which is thirty (30) days after the Closing Date (or the first Business Day thereafter if such date is not a Business Day), the provisions of the relevant Sublease, Direct Lease, license agreement or services agreement regarding late charges and default interest shall apply and provided further that Purchaser acknowledges that no Seller or

12

any Affiliate of a Seller shall have any liability with respect to any payments which arise after the Closing Date under any Real Estate Lease being assigned by a Seller to a Purchaser or Designated Purchaser or with respect to the Owned Real Estate, whether or not such payments become due on or before the date which is thirty (30) days after the Closing Date.

21. Santa ▇▇▇▇▇ Services. The Parties agree that, effective from and including the day immediately following the expiration or termination of the Omnibus Services Agreement dated the date hereof, but in no event earlier than sixty (60) days from the date hereof, at the building located at ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇ ▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ (“SC-100”) a portion of which is the subject of a Sublease (the “Santa ▇▇▇▇▇ Sublease”), and through and including the date on which the Santa ▇▇▇▇▇ Sublease expires or otherwise terminates, Purchaser shall provide, or cause a third party services provider to provide, services to any Seller, any Affiliate of a Seller and any subtenant of a Seller from time to time occupying space in SC-100 in accordance with this Section 24. Such services shall at a minimum include the services set forth on Schedule A-21 hereto, which are all the services being provided by Sellers or Sellers service providers to any such parties occupying space in SC-100 as of the date hereof. Sellers shall pay to Purchaser in advance on the first day of each month a fee equal to the lesser of (i) 100% of Purchaser’s costs of providing such services and (ii) the aggregate amount being paid by Sellers as of the date hereof as consideration for such services, plus in either instance any and all taxes (the “Sellers Services Fee Cap”) assessed on such payment. Purchaser further acknowledges that the Sellers Services Fee Cap shall not escalate on an aggregate basis at any time during the original term of the Santa ▇▇▇▇▇ Sublease; provided that the Sellers Services Fee Cap shall not apply to, and Sellers shall be responsible for paying all of Purchaser’s incremental costs for, any increase in the kind, quality, scope or frequency of any such services, if requested or consented to in writing by Sellers. Purchaser and Sellers shall cooperate with each other in good faith to facilitate a smooth transition of services from Sellers’ services providers under the Omnibus Services Agreement to Purchaser’s services providers hereunder. Upon request by Sellers, Purchaser may in any or all months elect to allow payment of the Sellers Services Fee Cap by Sellers in the form of a credit to Purchaser against any rents or other amounts due under the Santa ▇▇▇▇▇ Sublease. Notwithstanding any provision to the contrary herein, under no circumstances shall Purchaser be obligated to provide any Services to any Seller or any tenant, subtenant or occupant of SC-100 after the expiration or earlier termination of the Santa ▇▇▇▇▇ Sublease.

22. Assignment of Canberra Lease. The Parties agree that, subject to Sections 2.1.6(d), 2.1.10 and 5.13 of the ASSA and the receipt of any required Consent, the Non-365 Real Estate Lease relating to property located at National Capital Centre, Block 2, ▇▇▇▇▇▇▇ ▇▇, ▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇ in Canberra, Australian Capital Territory shall be assigned to the Purchaser or a Designated Purchaser as promptly as possible following Closing.

23. PGP. With respect to premises in Mumbai, India occupied by Nortel Networks (India) Private Limited pursuant to a Leave and License Agreement, the Parties agree that (i) Sellers will arrange for the issuance of visitor passes to the employees of Purchaser or Affiliates of Purchaser on a daily basis commencing the first Business Day following the

13

Closing Date and ending no later than January 29, 2010, at no cost to Purchaser, in order to facilitate Purchaser’s transitional operation of the Business out of such premises and removal of Assets from such premises, and (ii) Purchaser must complete its removal of Assets from such premises by no later than January 29, 2010. Sellers agree to cooperate in good faith to arrange for the issuance of additional daily visitor passes to employees of Purchaser or Affiliates of Purchaser upon request by Purchaser.

24. Tenant Services Guide.

Attached hereto as Exhibit A-24 is the Sellers’ Tenant Services Guide, which outlines the policies, procedures and guidelines applicable to services provided by Sellers across their global real estate portfolio, including Sellers’ policies on parking, drug and alcohol use, solicitation, demising, signage and security services (the Tenant Services Guide, together with the foregoing policies and any other policies, procedures or guidelines referenced therein is collectively referred to as the “Tenant Services Guide”). Notwithstanding anything to the contrary in the Tenant Services Guide, the Parties agree that (i) the services to be provided by Sellers or Sellers’ service providers at each site subject to a Sublease, Direct Lease, license agreement, or services agreement shall be substantially the same in kind, quality, scope, and frequency as the services provided by Sellers or Sellers’ service providers to the applicable site during the one year period prior to the Closing Date and (ii) in the event of any conflicts or inconsistencies between any term, provision, policy, procedure or guideline in the Tenant Services Guide (including the Links to Important Information section thereof relating to demising parking, signage and other policies and guidelines of Sellers) and the terms of any Sublease, Direct Lease, license agreement or services agreement (including the service schedules attached thereto), the terms of the applicable Sublease, Direct Lease, license agreement or services agreement (including the service schedules attached thereto) shall govern and control. Sellers agree that they will not apply or enforce the Tenant Services Guide in an arbitrary or discriminatory manner against Purchaser or any Designated Purchaser. Subject to the foregoing provisions of this Section 24, Purchaser agrees to abide by the policies, procedures and guidelines set forth in the Tenant Services Guide.

25. Deferred Transfer Purchased Assets.

The repair and return inventory held by Sellers for the Business in the following jurisdictions shall be Deferred Transfer Purchased Assets: Argentina, Bahamas, Barbados, Colombia, Costa Rica, Ecuador, Guatemala, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇, and Hong Kong. The Parties will work cooperatively to complete the sale of such assets pursuant to Section 2.1.1 by January 31, 2010. The sale of any such asset to Purchaser or a Designated Purchaser shall be complete upon the shipment of the asset to Purchaser, a Designated Purchaser, a customer of the Business or a Purchaser-designated repair hub.
