Except as described on Schedule 5.20(g), Seller has not received written notice, or a copy of any written notice, of any proposed or pending special taxes, assessments, fees or other impositions affecting or which may affect the Owned Real Property or any part thereof or any of the Leased Real Property.

5.21 Brokers, Finders, etc. Except as described on Schedule 5.21, Seller is not a party to any agreement with any finder or broker, or in any other way obligated to any finder or broker, for any commissions, fees or expenses in connection with (x) the origination, negotiation, execution or performance of this Agreement, the other Transaction Documents, the transactions contemplated hereby or thereby or the Real Property Leases or (y) the acquisition, leasing or disposition of the Owned Real Property.

Except for the representations and warranties contained in this Article 5, neither Seller nor any other Person makes any other express or implied representation or warranty on behalf of Seller, including any representation or warranty as to the probable success or profitability of the ownership, use or operation of the Business or the Acquired Assets by Buyer after the Closing.

ADDITIONAL AGREEMENTS

7.1 Conduct of the Business. Seller covenants and agrees that, between the date hereof and the Closing Date, it will cause the Business to be conducted only in the Ordinary Course of Business, and will use its commercially reasonable efforts to maintain and preserve intact the Acquired Assets, the Business and its material relationships with its suppliers and its customers. Without limiting the generality of the foregoing, between the date hereof and the Closing Date, Seller shall not without the prior written consent of Buyer:

(a) sell, lease, transfer, mortgage, encumber or otherwise dispose of any Acquired Asset, real, personal or mixed;

(b) increase the rate of compensation of, or pay or agree to pay any benefit to, officers or employees of the Business, except in the Ordinary Course of Business or as may be required by any existing plan, agreement or arrangement, including, without limitation, any Plan;

(k) make any material amendments or modifications to any of the Assumed Contracts, except in the Ordinary Course of Business; or

Notwithstanding the foregoing, neither the issuance of Additional remedy Tickets nor any action taken by Seller in furtherance of, and in a manner consistent with the requirements of, the Project (as defined in the Transition Services Agreement) shall be deemed to violate the provisions of this Section 7.1.

7.2 Access to Information. (a) From the date hereof until the Closing, upon reasonable notice, Seller shall, and shall cause its respective officers, employees, auditors and agents to, (i) afford the officers, employees, agents and representatives of Buyer, at Buyer’s sole expense, access, during normal business hours, to the offices, personnel, properties, books and records of Seller relating to the Business and (ii) furnish to the officers, employees, agents and representatives of Buyer such additional financial and operating data and other information relating to the Business as they may from time to reasonably request; provided, however, that such investigation shall not unreasonably interfere with any of the businesses or operations of Seller; provided, further, that Seller shall not be required to provide such access or disclosure to the extent that such access and disclosure would violate the terms of any agreement to which Seller is bound or any Law or result in any loss of attorney-client or other privilege. Buyer and its representatives will at all times comply with all rules and procedures relating to the foregoing as may be communicated to them by Seller or its representatives, and will hold in confidence all confidential information obtained from Seller in accordance with the provisions of the Confidentiality Agreement. In addition, Buyer acknowledges and confirms that it and its representatives are and remain subject to the Confidentiality Agreement.

(b) In order to facilitate the resolution of any claims made against or by Seller or for any other reasonable purpose (including the preparation of or audit of any Tax Returns of Seller), for a period of seven (7) years after the Closing, Buyer shall (i) retain the records relating to the Acquired Assets and the Business delivered by Seller to Buyer corresponding to periods prior to the Closing in a manner reasonably consistent with the prior practice of Seller and (ii) upon reasonable notice, afford the officers, employees, agents and representatives of Seller reasonable access during normal business hours, to such books and records (including the right to make, at Seller’s expense, photocopies).

(c) In order to facilitate the resolution of any claims made against or by Buyer or for any other reasonable purpose, for a period of seven (7) years after the Closing, Seller shall (i) retain any books and records relating to the Acquired Assets and the Business for periods prior to the Closing which have been retained by it in accordance with this Agreement and (ii) upon reasonable notice, afford the officers, employees, agents and representatives of Buyer reasonable access during normal business hours, to such books and records (including the right to make, at Buyer’s expense, photocopies).

(d) At Buyer’s request, at any time within one (1) year after the Closing, Seller shall provide to Buyer’s designated independent auditor access to the books and records of the Acquired Assets, and all related information regarding the Acquired Assets for the period commencing January 1, 2005 through the Closing Date. In connection with the foregoing audit, Seller shall provide to such auditor a representation letter in substantially the form of Exhibit I attached hereto, with such changes as may be necessary to make the representations set forth therein true and correct as of the date on which such representation letter is to be delivered.

7.3 Mutual Cooperation; Further Assurances. (a) Seller and Buyer agree to use their respective commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to consummate and make effective the transactions contemplated by this Agreement and the other Transaction Documents, including all of the following: (i) subject to 7.3(b), obtaining all Consents as are necessary for the consummation of the transactions contemplated by this Agreement and the other Transaction Documents, provided, however, other than payment by Seller of reasonable legal fees incurred by a landlord in connection with a request for consent to the assignment of a Real Property Lease as contemplated hereby, neither Seller nor Buyer shall be required to make any payment to any third party in order to obtain any such consent; (ii) filing timely and promptly all required notices, applications, reports and requests; (iii) defending all proceedings challenging the consummation of the transactions contemplated by this Agreement and the other Transaction Documents; and (iv) executing and delivering any additional documents necessary to consummate the transactions contemplated by this Agreement and the other Transaction Documents.

(b) Seller shall use commercially reasonable efforts to obtain, and Buyer shall cooperate in a reasonable manner with such efforts to obtain, the consent of any party or parties to each Real Property Lease and each Non-Assignable Contract that is not a Colocation Contract to the assignment thereof by Seller to Buyer; provided, however, other than payment by Seller of reasonable legal fees incurred by a landlord in connection with a request for consent to the assignment of a Real Property Lease as contemplated hereby, neither Seller nor Buyer shall be required to make any payment to any such third party in order to obtain any such consent. Without limiting the foregoing, Buyer and Seller each agree that (a) if it executes a consent of the landlord, and the consent imposes an obligation upon such party to provide landlord with information, such party shall provide landlord with such information as and when required by the consent, and (b) if, following landlord’s receipt of the information set forth in the foregoing clause (a), the landlord has the right to revoke its consent, the Closing shall be adjourned until the date which is one business day following the expiration of the period in

which landlord may revoke its consent. Buyer and Seller shall, following the Closing Date, use commercially reasonable efforts and co-operate with each other to obtain the consent of any party or parties to each Colocation Contract which is a Non-Assignable Contract to the assignment thereof by Seller to Buyer and, if necessary, the separation of such Non-Assignable Contract into an assignable Contract relating to the Colocation Rights and a separate Contract relating to any other services to be provided thereunder prior to such assignment; provided, however, neither Seller nor Buyer shall be required to make any payment to any such third party in order to obtain any such consent. As soon as practicable following receipt of any such consent, Seller shall assign and Buyer shall assume all of the rights and obligations of Seller with respect to such Contract, such assignment and assumption to be evidenced by the execution of an Assumption Agreement. If any such consent is not obtained, or if an attempted assignment of a Non-Assignable Contract would be ineffective or would affect the rights of Seller thereunder such that Buyer would, in fact, not receive all of Seller’s rights under the Non-Assignable Contract or such that Seller’s rights under any portion of the Contract which does not relate to Colocation Rights would be impaired, such Non-Assignable Contract shall not be assigned, shall be an Excluded Contract hereunder and the obligations of the Buyer and Seller with respect to such Non-Assignable Contract from and after the Closing and prior to execution of an Assumption Agreement reflecting the assignment and assumption of such Contract shall be governed by the Transition Services Agreement and (x) Buyer shall pay all Liabilities of Seller arising under any such Non-Assignable Contract and (y) such Liabilities shall be treated as “Assumed Liabilities” for all purposes of this Agreement, in the case of (x) and (y) to the same extent that such Liabilities would have been Assumed Liabilities if the consent to the assignment of the applicable Non-Assignable Contract had been obtained.

(c) Seller is party to certain Contracts (the “Package Contracts”) under which Seller has agreed to provide a limited number of its small customers with one colocation rack, one megabit of IP transport and the associated power at a single fixed price. In order to facilitate the assignment of the Package Contracts to Buyer and in light of the fact that it is not feasible to determine the portion of the Package Contract consideration specifically allocable to the IP transport, Seller and Buyer hereby agree that notwithstanding that IP transport services provided by Seller are not included in the Colocation Services provided by the Business and, as a result, Contracts to provide IP transport services are not being assigned to Buyer and the revenues associated with the provision of IP transport services after the Closing Date to customers of the Business are being retained by Seller, Seller hereby agrees to provide the IP transport services required to be provided under the Package Contracts free of charge during the remaining term (excluding any renewals or extensions made after assignment) of each Package Contract assigned to Buyer on or after the Closing Date.

(d) Prior to or within two (2) Business Days after the Execution Date, Seller shall request from each landlord under each of the Real Property Leases the execution of an estoppel certificate in the form attached hereto as Exhibit G-1, G-2 or G-3, as applicable.

(e) Seller and Buyer shall reasonably cooperate with the other and furnish the other such necessary information and assistance as the other may reasonably request in connection with the matters described in this Section 7.3.

(f) At any time and from time to time after the Closing, each of the parties agrees to cooperate with each other and to execute and deliver such other documents, instruments of transfer or assignment, files, books and records and do all such further acts and things as may be reasonably required to carry out the transactions contemplated by this Agreement and the other Transaction Documents.

7.4 Updating of Schedules. Prior to the Closing, if as a result of any event or condition occurring or existing subsequent to the date hereof not caused by the breach by Seller of any covenants in this Agreement, any representation or warranty contained in Article 5 has become inaccurate, Seller may update the Schedules to Article 5 to correct such representation or warranty, and the update to the Schedules shall be deemed an amendment to this Agreement upon delivery of such updated Schedules to Buyer. Any indemnification obligation of Seller under Article 11 of this Agreement for the breach of a representation or warranty shall be based on the Schedules as so updated and not the earlier Schedules; provided, however, that solely for purposes of determining whether the condition in Section 8.3(a) has been satisfied, the changes in the updated Schedules shall be disregarded.

7.5 Employees. (a) Prior to the Closing, Buyer shall offer employment effective as of the Closing Date to each of the employees of Seller listed on Schedule 7.5, at a salary or compensation rate at least equal to the salary or compensation rate applicable to such employee’s employment immediately prior to the Closing. Any employees of Seller who accept such offers of employment with Buyer shall be referred to as the “Transferred Employees.”

(b) To the extent Buyer maintains welfare plans that are similar in scope to the welfare Plans of Seller applicable to employees of the Business prior to Closing, Buyer will (i) waive all limitations as to preexisting conditions, exclusions and waiting periods applicable to Transferred Employees under any such welfare plan of Buyer, other than conditions, exclusions or waiting periods that are already in effect under welfare Plans of Seller with respect to Transferred Employees and which have not satisfied prior to the Closing Date, and (ii) provide each Transferred Employee with credit for any co-payments and deductibles paid by a Transferred Employee prior to the Closing Date under welfare Plans of Seller for purposes of satisfying any applicable deductible or out-of-pocket requirements under any welfare Plan that such Transferred Employee is eligible to participate in after the Closing Date.

(c) Except as set forth in this Section 7.5, Buyer is under no obligation to offer employment to any employees of Seller and Buyer shall have no obligation or Liability for (and Seller shall retain the obligation and Liability for) any salary, compensation, benefits, severance or other amounts owed to or claimed by any employee of Seller, including for periods prior to the Closing or as a result of Buyer’s election not to offer employment to such employee as of the Closing. Nothing in this Agreement shall confer upon any employee of Seller any expectation, entitlement or right to employment with Buyer or any compensation, benefits or severance thereunder.

7.6 Public Disclosures. Prior to the Closing, neither Seller nor Buyer (nor any of their respective Affiliates) will issue any press release or make any other public disclosures

concerning this Agreement, the other Transaction Documents or the transactions contemplated hereby or thereby without the prior written consent of the other. Notwithstanding the preceding sentence, nothing in this Section 7.6 will preclude any Party (or its Affiliates) from making any disclosures required by any Governmental Authority, Law or stock exchange; provided, however, that the Party (or its Affiliate) required to make public disclosure shall use reasonable efforts to allow the other Party reasonable time to comment in advance on such public disclosure.

7.7 “As Is” Condition of the Acquired Assets. Except as may be specifically provided in this Agreement, Buyer expressly understands and agrees that it shall accept the sale, assignment, transfer, conveyance and delivery by Seller of all of the Acquired Assets on an “As Is Where Is” basis on the Closing Date regardless of the condition of the Acquired Assets and whether Buyer has inspected and examined them. EXCEPT AS MAY BE SPECIFICALLY PROVIDED IN THIS AGREEMENT, SELLER MAKES NO REPRESENTATION OR WARRANTY WITH RESPECT TO THE VALUE, CONDITION OR USE OF THE ACQUIRED ASSETS, WHETHER EXPRESSED OR IMPLIED, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR USE.

7.8 Bulk Sales. Buyer hereby waives compliance with any bulk sales, fraudulent conveyance or similar laws which may be applicable to the transactions contemplated hereby, subject to the indemnities of Seller contained in this Agreement. Nothing in this paragraph will stop or prevent either Buyer or Seller from asserting as a bar or defense to any proceeding brought under the bulk sale law that such law does not apply to the sale contemplated under this Agreement.

7.9 Tax Allocations. If for purposes of determining any ad valorem Taxes, real property Taxes, personal property Taxes, and similar obligations (“Property Taxes”) attributable to the Acquired Assets the applicable taxable period does not terminate on the Closing Date (any such period, a “Straddle Period”), then such Property Taxes with respect to the Straddle Period shall be apportioned as of the Closing Date between Seller and Buyer determined by prorating such Property Taxes on a daily basis over the entire tax period. If the Closing occurs before the Tax rate is fixed for the then current fiscal or calendar year, whichever is applicable, the proration of the corresponding Taxes shall be on the basis of the Tax rate for the last preceding year applied to the latest assessed valuation.

7.10 Use of Name. Except as specifically provided in this Section 7.10, from and after the Closing, Buyer shall not use the name or logos for the name “AboveNet.” Promptly following the Closing, Buyer shall cause all references to AboveNet to be removed from any signage or other identifying information on or at any of the Acquired Assets. Seller hereby grants to Buyer a limited, worldwide, non-exclusive license to use such “AboveNet” name during the 90-day period following the Closing Date solely in connection with notifying customers and suppliers of the sale of the Business to Buyer.

7.11 Confidentiality. Seller shall keep, and shall use reasonable efforts to cause its shareholders, directors, officers, employees, consultants, representatives and agents to keep,

any and all confidential and proprietary information relating to the Business, the business operations and prospects (including, but not limited to, customer lists and related information) of the Business, services and know-how relating to the Business and used by Seller solely in the operation of the Business (“Confidential Information”) confidential and shall not disclose such Confidential Information to any Person; provided, however, that the Seller may disclose such information that (i) is or becomes publicly available other than by disclosure by Seller or any agent thereof or (ii) Seller is required to disclose by Law, Governmental Authority or stock exchange regulation or in order to enforce the terms of this Agreement, but Seller will give the Buyer adequate advance notice so that the Buyer may seek a protective order or take other reasonable actions to preserve the confidentiality of such information.

7.12 Insurance Proceeds, Litigation Rights. In the event that any property owned or leased by the Seller and used primarily in the conduct of the Business or otherwise material to the Business suffers any material damage, destruction or other casualty loss, and the Closing occurs in accordance with the terms hereof, the Seller shall surrender to the Buyer (i) all insurance proceeds received by Seller with respect to such damage or loss and (ii) all rights of Seller with respect to any causes of action, whether or not litigation has commenced on the Closing Date, in connection with such damage or loss. Nothing in this Section 6.6 shall be construed to limit or prejudice the Buyer’s right not to consummate the transactions contemplated hereby if all of the conditions set forth in Section 8.3 are not satisfied or waived.

7.13 Notice of Litigation. Seller shall notify promptly the Buyer of any actions or proceedings of the type described in Section 5.9 that are commenced or, to the Knowledge of the Seller, threatened from the date hereof through the Closing Date. Buyer shall promptly notify Seller of any actions or proceedings of the type described in Section 6.9 that are commenced or, to the Knowledge of the Buyer, threatened from the date hereof through the Closing Date.

7.14 Exclusivity. As an inducement to the Buyer to enter into this Agreement, and in consideration of the time and expense which it has devoted and will devote to the transactions contemplated hereby during such period, subsequent to the execution of this Agreement and until the earlier of (i) the Closing Date and (ii) the termination of this Agreement in accordance with Section 10.1, neither of the Seller nor any of its shareholders, directors, members, managing members, managers, officers or agents (including, without limitation, any investment banker, attorney or accountant retained or acting on behalf of Seller or any shareholder, director, member, managing member, manager or officer of Seller) will, directly or indirectly, (i) initiate, solicit, encourage, entertain or respond to any inquiry or proposal with respect to a merger, consolidation, share exchange, business combination, liquidation, or dissolution (unless such transaction shall be structured in a manner that is consistent with, and does not adversely affect, the Buyer’s rights under this Agreement) or sale of all or a portion of the assets of the Business (an “Acquisition Proposal”), or (ii) enter into any discussions, negotiations or agreements concerning an Acquisition Proposal with, or disclose any information concerning the Business, its business or properties or afford any access to its properties, books and records to, or otherwise assist or facilitate any effort relating to an Acquisition Proposal, by any Person. The Seller will immediately cease any existing discussions with any Persons concerning any Acquisition Proposal. The Seller or its shareholders, directors, members, managing members, managers,

officers or agents will, as the case may be, promptly notify the Buyer regarding any contact between Seller or its shareholders, directors, members, managing members, managers, officers or agents and any other Person regarding any inquiry or contact (and any material terms thereof) with respect to an Acquisition Proposal, unless inconsistent with the fiduciary obligations of Seller or its shareholders, directors, members, managing members, managers, officers and agents.

7.15 Title Commitments; Survey; Searches. Buyer’s obligation to purchase the Owned Real Property, assume the Real Property Leases and consummate the transactions contemplated hereby shall also be subject to and conditioned upon Buyer’s having approved the condition of title to the Fee Owned Real Property and Leased Real Property in the manner provided for in this Section 7.15.

(a) Title Commitment. Buyer, at its sole cost and expense, has caused the Title Company to deliver a commitment (the “Title Commitment”) to Buyer for a new title insurance policy (the “Title Policy”) with respect to the Owned Real Property for the benefit of the Buyer as the fee owner of the Owned Real Property, issued by the Title Company showing Seller as the previous fee owner of the Owned Real Property and Buyer as the new fee owner of the Owned Real Property. Buyer, at its sole cost and expense, has caused the Title Company to deliver a commitment (each a “Leasehold Title Commitment”) to Buyer for a leasehold owner’s title insurance policy (each a “Leasehold Title Policy”) with respect to each of the Real Property Leases and the Leased Real Property for the benefit of the Buyer as the assignee of the leasehold estate in the Leased Real Property pursuant to the Real Property Leases. The Title Commitment and Leasehold Title Commitments are attached hereto as Schedule 7.15(a).

(b) Survey. Seller shall provide Buyer with a copy of Seller’s existing survey of the Owned Real Property. Buyer, at its sole cost and expense, shall obtain an update of such survey (the “Survey”) of the Owned Real Property, in a form acceptable to, and certified to, Buyer and the Title Company.

(c) Searches. Buyer, at its sole cost and expense, may obtain current UCC, tax lien and judgment searches with respect to Seller to identify liens, security interests and adverse claims affecting the Seller’s interest in the Owned Real Property, the Real Property Leases, the Leased Real Property, the Colocation Contracts and/or the other Acquired Assets (collectively, “Searches”).

(d) Real Property Permitted Liens. Buyer shall have the right, up until the Closing, to object in writing (“Buyer’s Exception Notice”) to any title matters that are Liens and (x) to the extent related to the Owned Real Property, are not Real Property Permitted Liens or (y) to the extent related to the Leased Real Property, are not Permitted Liens; provided that Buyer has reviewed the Title Commitment and Leasehold Title Commitments as attached hereto as Schedule 7.15(a), and has accepted, and agreed not to object to, any title matters that are shown in the pre-printed exceptions to or the exceptions set forth on Schedule B-Part 2 to the Title Commitment and Leasehold Title Commitments. Buyer shall have the right to amend Buyer’s Exception Notice to object to any title matters that are Liens and (x) to the extent related to the

Owned Real Property, are not Real Property Permitted Liens or (y) to the extent related to the Leased Real Property, are not Permitted Liens, in each case which are disclosed in any supplemental reports or updates to the Title Commitment, Leashold Title Commitments or Survey delivered to Buyer prior to the Closing provided that Buyer objects to the same within three (3) Business Days after Buyer’s receipt of the applicable supplemental reports or updates to the Title Commitment but in no event after Closing (“Subsequent Title Defects”). Unless Buyer shall timely object to the Liens as aforesaid, such Liens shall be deemed to constitute additional Real Property Permitted Liens. Any exceptions which are timely objected to by Buyer as aforesaid shall be herein collectively called the “Title Objections.” Seller may elect (but shall not be obligated) to remove or cause to be removed, or insured over, at its expense, any Title Objections, and shall be entitled to a reasonable adjournment of the Closing (not to exceed forty-five (45) days) for the purpose of such removal. Seller shall notify Buyer in writing within five (5) days after receipt of any Buyer’s Exception Notice whether Seller elects to remove the same. If Seller is unable to endorse over any Title Objections prior to the Closing in a manner reasonably acceptable to the Title Company or does not arrange to remove such Title Objection or if Seller elects not to remove one or more Title Objections, Buyer may elect to either (a) terminate this Agreement by giving written notice to Seller and Escrow Agent prior to the Closing, in which event the entire ▇▇▇▇▇▇▇ Money Deposit shall be paid to Buyer or (b) waive such Title Objections, in which event such Title Objections shall be deemed to constitute additional Real Property Permitted Liens and the Closing shall occur as herein provided without any reduction of or credit against the Purchase Price. Notwithstanding anything to the contrary contained herein, any Lien which is a financial encumbrance such as a mortgage, deed of trust, or other debt security, or an attachment, judgment, mechanic’s or materialmen’s lien caused or incurred by Seller, or a lien for delinquent real estate taxes and delinquent assessments, which is outstanding against title to the Owned Real Property, or any part thereof, and is not a Real Property Permitted Lien or is outstanding against any of the Leased Real Property or any of the Real Property Leases and is not a Permitted Lien, that is revealed or disclosed by the Title Commitment, Leasehold Title Commitment and/or the Searches (herein such matters are referred to as “Financial Encumbrances”) shall automatically, and without any requirement for Buyer to provide notice thereof to Seller, be deemed not to be a Title Objection and Seller hereby covenants to remove or insure over all such Financial Encumbrances which are less than that portion of the Purchase Price allocated to the Owned Real Property on or before the Closing Date. Further, notwithstanding anything to the contrary contained herein, Seller shall be obligated to remove (i) any and all Title Objections that are Subsequent Title Defects created or permitted by Seller after the Execution Date and (ii) any other Title Objections, provided, however, that Seller shall not be required to incur costs in excess of $100,000 in the aggregate or pay any amounts for consents of third parties in order to remove such Title Objections.

7.16 Deed. Seller shall convey the Owned Real Property to Buyer by the Real Property Deed.

(iv) Other than claims based on fraud, willful misconduct or for specific performance, injunctive or other equitable relief (to the extent permitted by this Agreement), the indemnity provided in this Article 11 and, to the extent applicable, Section 4 of the Transition Services Agreement shall be the sole and exclusive remedy of the Indemnified Buyer Group against Seller at law or equity for any breach of or inaccuracy in any representation or warranty contained in this Agreement or any certificate delivered at Closing.

respect to a third party claim for which a member of the Indemnified Seller Group is seeking indemnification hereunder.

11.4 Claim Procedures. Any Indemnified Party seeking indemnification hereunder for any Loss or potential Loss arising from a claim asserted against the Indemnified Party (each, a “Claim”) shall give written notice thereof to the Indemnifying Party promptly after such Indemnified Party becomes aware of the facts giving rise to such potential Claim; provided, however, that the Indemnified Party shall not be foreclosed from seeking indemnification pursuant to this Article 11 as a result of any failure to provide timely notice of a Claim unless the Indemnifying Party has been damaged or prejudiced as a result of such delay. Such notice shall specify in reasonable detail the nature and basis of, and the estimated resulting Losses from, the Claim and shall include a copy of all papers served with respect to such claim. For purposes of this Section 11.4, receipt of written notice of any claim from a third party that may give rise to a Claim on behalf of such Indemnified Party shall constitute becoming aware of the facts giving rise to a potential Claim and shall require notice to the Indemnifying Party as provided in the first sentence of this Section 11.4.

11.5 Additional Procedures for Third-Party Claims. If a Claim arises from a claim asserted against an Indemnified Party by a Person unrelated to the Indemnified Party (each, a “Third-Party Claim”), the Indemnifying Party shall have the right, at its sole option and expense, to be represented by counsel of its choice, which counsel shall be reasonably satisfactory to the Indemnified Party, and, subject to the last sentence of this Section 11.5, to

defend against, negotiate, settle or otherwise deal with any Third-Party Claim subject to indemnity hereunder. If the Indemnifying Party declines to assume the defense of such Third-Party Claim, it shall be liable for all costs and expenses of defending such claim incurred by the Indemnified Party, including reasonable fees and disbursements of counsel. If the Indemnifying Party has assumed such defense, the Indemnified Party shall be entitled, at its own cost and expense, to participate in the defense of any such Third-Party Claim. If the Indemnifying Party has assumed such defense and it is later determined that such Third-Party Claim was not a Claim for which the Indemnifying Party is required to indemnify the Indemnified Party under this Agreement, the Indemnified Party shall reimburse the Indemnifying Party for all its reasonable costs and expenses with respect to such settlement or defense, including fees and expenses of counsel, within sixty (60) days of such determination. In connection with the defense of any Third-Party Claim subject to indemnification under this Article 11, the Indemnifying Party and the Indemnified Party shall render to each other such assistance as may reasonably be required in order to ensure proper and adequate defense of such claim. Neither party shall, without the prior written consent of the other party, which consent shall not be unreasonably delayed, withheld or conditioned, settle, compromise or offer to settle or compromise any Third Party Claim on a basis which would result in the imposition of a consent order, injunction or decree which would restrict the future activity or conduct of the other party or any Affiliate thereof or if such settlement or compromise does not include an irrevocable and unconditional release of the other party for any liability arising out of such Third Party Claim or any related Claim.

11.6 Reduction of Losses. (a) Each of the Parties shall use commercially reasonable efforts to mitigate any Losses for which it may seek indemnification under this Article 11, including exerting such efforts to collect the proceeds of any insurance that would have the effect of reducing any such Losses (in which case such proceeds shall reduce such Losses). In calculating any amount of Losses recoverable pursuant to this Article 11, the amount of such Losses shall be reduced by any insurance proceeds actually received relating to such Loss, net of any related deductible and any expenses to obtain such proceeds, any recoveries from third parties pursuant to indemnification (or otherwise) with respect thereto, net of any expenses incurred by the indemnified party in obtaining such third party payment and the amount of any net Tax Benefit resulting from the incurrence or payment of such Losses. If, at any time, the indemnification payments made by an Indemnifying Party to an Indemnified Party pursuant to this Agreement exceed the Losses of such Indemnified Party as calculated in accordance with the previous sentence (whether as a result of a subsequent receipt by the Indemnified Party of insurance proceeds, third party indemnification payments, Tax Benefits or otherwise), the Indemnified Party shall promptly remit to the Indemnifying Party the full amount of such excess.

(b) For purposes of this Section 11.6, “Tax Benefit” means the amount by which the Tax liability of the party (or group of entities including the party) making the Claim under this Article 11 is reduced below the amount which it would otherwise be required to pay but for the circumstances giving rise to the Losses underlying such Claim. Each party shall promptly inform the other party of the extent of any Tax Benefit realized and shall permit such other party’s independent accountants to reasonably verify the extent of such Tax Benefit.

(c) Nothing in this Section 11.6 shall impose upon any Party any obligation to obtain insurance coverage for any Losses, whether occurring before or after the Closing Date.

11.7 Subrogation. Any Indemnifying Party shall be subrogated to the Indemnified Party’s rights of recovery to the extent of any Losses under Article 11 satisfied by the Indemnifying Party. The Indemnified Party shall permit the Indemnifying Party to use the name of the Indemnified Party and the names of the Indemnified Party’s Affiliates to the extent such use is required by Law or is otherwise commercially reasonable in any transaction or any proceeding to enforce such rights, shall execute and deliver such instruments and papers as are reasonably necessary to assign such rights and shall assist in the exercising of such rights thereof, including reasonable access to books and records and employees (if required).

11.8 No Double Recovery. No party shall be entitled to indemnification or reimbursement under any provision of this Agreement for any amount to the extent such party or its Affiliate has been indemnified or reimbursed for such amount under any other provision of this Agreement or any document executed in connection with this Agreement, including the Transition Services Agreement.

11.9 Treatment of Indemnity Payments Between the Parties. Unless otherwise required by applicable Law, all indemnification payments hereunder or with respect to claims made under Section 4(b)(i)(a) or 4(b)(ii)(a) of the Transition Services Agreement shall constitute adjustments to the Purchase Price for all Tax purposes, and no party shall take any position inconsistent with such characterization.
