Exhibit 99.4

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders

IXEurope plc

We have audited the accompanying consolidated balance sheets of IXEurope plc as of 31 December 2006 and 2005 and the related consolidated income statement, consolidated statement of recognized income and expense and consolidated cash flows for each of the three years in the period ended 31 December 2006. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of IXEurope plc at 31 December 2006 and 2005, and the results of its operations and its cash flows for each of the three years in the period ended 31 December 2006, in conformity with International Financial Reporting Standards.

International Financial Reporting Standards vary in certain significant respects from accounting principles generally accepted in the United States of America. Information relating to the nature and effect of such differences is presented in Note 27 to the consolidated financial statements.

Notes to the consolidated financial statements

1 Accounting policies

IX Europe plc (the “Company”) is a company domiciled in England. The consolidated financial statements of the Company for the 3 years ended 31 December 2006 comprise the Company and its subsidiaries (together referred to as the “Group”).

Statement of Compliance

The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRSs), its interpretations adopted by the International Accounting Standards Board (IASB), as adopted by the EU and with those parts of the Companies Act 1985 applicable to companies preparing accounts under IFRS.

The financial statements for the year ended 31 December 2004 were originally prepared under UK GAAP but were restated under IFRS in the comparative figures published in the financial statements for the year ended 31 December 2005.

The preparation of financial statements in conformity with IFRSs requires management to make judgements, estimates and assumptions that affect the application of policies and reported amounts of assets and liabilities, income and expenses. The estimates and associated assumptions are based on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis of making the judgements about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised if the revision affects only that period, or in the period of revision and future periods if the revision affects both current and future periods.

Standards, Amendments And Interpretations Effective 2006 But Not Relevant

The following standards, amendments and interpretations to published standards are mandatory for accounting periods beginning on or after 1 January 2006 but they are not relevant to the Group’s operations for the year ended 31 December 2006:

Standards and Interpretations to Existing Standards That Are Not Yet Effective And Have Not Been Adopted Early By The Group

The following standards and interpretations to published standards have been published that are mandatory for the Group’s accounting periods beginning on or after 1 January 2007 or later periods but which the Group has not adopted early:

IFRS 7—Financial Instruments: Disclosures and the complementary amendment to IAS 1, Presentation of financial statements – capital disclosures (effective for annual periods beginning on or after 1 January 2007). IFRS 7 introduces new disclosures relating to financial instruments. The Group will apply IFRS 7 from 1 January 2007, but it is not expected to have an impact on the classification or valuation of the Group’s financial instruments.

IFRIC 8—Scope of IFRS 2 (effective for annual periods beginning on or after 1 May 2006). IFRIC 8 clarifies that IFRS 2 Sharebased Payment applies to arrangements where an entity makes share-based payments for apparently nil or inadequate consideration. The Group will apply IFRIC 8 from 1 January 2007, but it is not expected to have an impact on the Group’s accounts.

IFRIC 10—Interim Financial Reporting and Impairment (effective for annual periods beginning on or after 1 November 2006). IFRIC 10 concludes that an entity shall not reverse an impairment loss recognised in a previous interim period in respect of goodwill or an investment in either an equity instrument or a financial asset carried at cost. The Group will apply IFRIC 10 from 1 January 2007 but it is not expected to have any impact on the Group’s accounts.

IFRS 8—Operating Segments (effective for annual periods beginning on or after 1 January 2009). IFRS 8 replaces IAS 14—Segmental Reporting and introduces new requirements relating to how segments are identified and disclosures required. The Company will apply IFRS 8 from 1 January 2009. The Group has yet to assess the impact this standard will have on the disclosure of segment results.

IFRIC 11—IFRS 2: Group and Treasury Share Transactions (effective for annual periods beginning on or after 1 March 2007). IFRIC 11 contains guidance on how an entity should account for share-based payment involving an entity’s own equity instruments in which the entity chooses or is required to buy its own equity instruments (treasury shares) to settle the share-based payment obligation, and guidance on the treatment when a parent grants rights to its equity instruments to employees of its subsidiary or a subsidiary grants rights to equity instruments of its parent to its employees in the individual entities’ financial statements. IFRIC 11 is not expected to have an impact on the Group because it does not intend nor is it required to purchase its own equity instruments to settle the share-based payment obligation and the individual entities do not produce accounts under International Financial Reporting Standards.

Interpretations To Existing Standards That Are Not Yet Effective And Not Relevant To The Operations Of The Group

IFRIC 7—Applying the Restatement Approach under IAS 29 Financial Reporting in Hyperinflationary Economies (effective for annual periods beginning on or after 1 March 2006). IFRIC 7 contains guidance on how an entity would restate its financial statements in the first year it identifies the existence of hyperinflation in the economy of its functional currency. As none of the Group entities has a currency of a hyperinflationary economy as its functional currency, IFRIC 7 is not relevant to the Group’s operations.

IFRIC 9—Reassessment of Embedded Derivatives (effective for annual periods beginning on or after 1 June 2006). IFRIC 9 concludes that an entity must assess whether an embedded derivative is required to be separated from the host contract and accounted for as a derivative when the entity first becomes a party to the contract. Subsequent reassessment is prohibited unless there is a change in the terms of the contract that significantly modifies the cash flows that otherwise would be required under the contract, in which case reassessment is required. IFRIC 9 is not relevant to the Group’s operations because none of the terms of the Group’s contracts have been changed.

IFRIC 12—Service Concession Arrangements (effective for annual periods beginning on or after 1 January 2008). IFRIC 12 clarifies how certain aspects of existing IASB literature are to be applied to service concession arrangements. IFRIC 12 is not relevant to the Group’s operations.

Basis of Consolidation

The consolidated financial statements include the financial statements of the Company and its subsidiary undertakings made up to 31 December 2006. The acquisition method of accounting has been adopted. Under this method the results of subsidiary undertakings acquired or disposed of in the period are included in the consolidated income statement from the date the parent gained control until such time control ceases. Control exists where the Company has the power to govern the financial and operating policies of an investee entity so as to obtain benefits from its activities.

Critical Accounting Estimates And Judgements

Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed reasonable under the circumstances.

Estimated Impairment Of Goodwill

The Group tests annually whether goodwill has suffered any impairment, in accordance with the accounting policy on goodwill. The recoverable amounts of cash-generating units are determined by value-in-use calculations. These calculations require the use of estimates (See Note 9)

Fair Value Of Share Option Grants

The fair value of share options granted in the year is estimated at the date of grant using a valuation technique. The Group has carefully considered the inputs into the valuation model based on future expectations and comparative companies.

Details of valuation technique used, and inputs for the models are disclosed in Note 13.

Foreign Currencies

Transactions entered into by the Group entities in a currency other than the currency of the primary economic environment in which it operates (the “functional currency”) are recorded at the rates ruling at the date of the transaction. Foreign currency monetary assets and liabilities are translated at the rates ruling at the balance sheet date. Exchange differences arising on the retranslation of unsettled monetary assets and liabilities are similarly recognised immediately in the income statement, except for foreign currency borrowings qualifying as a hedge of a net investment in a foreign operation.

On consolidation, the results of overseas operations are translated into sterling at rates approximating to those ruling when the transactions took place. All assets and liabilities of overseas operations, including goodwill arising on the acquisition of those operations, are translated at the rate ruling at the balance sheet date. Exchange differences arising on translating the opening net assets at opening rate and the results of overseas operations at actual rate are recognised directly in equity (the “foreign exchange translation reserve”).

Pension Costs

A number of Group companies operate defined contribution pension schemes. The assets of these schemes are held separately to those of the Group in independently administered funds. The pension cost charge represents contributions payable by the Group in the year.

Property, Plant And Equipment

Items of property, plant and equipment are stated at cost less accumulated depreciation and impairment provisions.

Where parts of an item of property, plant and equipment have different useful lives, they are accounted for as separate items of property, plant and equipment.

Depreciation is provided to write off the cost less the estimated residual value of tangible fixed assets by equal instalments over their estimated useful economic lives as follows:

Freehold land and assets in the course of construction are not depreciated.

Operating And Finance Leases

Operating lease rentals relating to colocation facilities are charged to cost of sales in the income statement on a straight line basis over the period of the lease.

Benefits received as an incentive to sign operating leases for colocation facilities are charged to the income statement on a straight line basis over the full length of the lease.

Assets acquired under finance leases are capitalised and the capital element of the lease rentals is included in creditors. Lease payments are analysed between capital and interest. The interest element is charged to the income statement over the period of the lease and is calculated so that it represents a constant proportion of the lease liabilities. The capital element reduces the balance owed to the lessor.

Assets under finance leases are depreciated over the shorter of the lease terms and the useful life of equivalent owned asset.

Where the Group has entered into a sale and leaseback arrangement resulting in a finance lease, any excess of sales proceeds over the carrying amount is deferred and amortised over the lease term.

Income Tax

Income tax on the loss for the year comprises current and deferred tax. Income tax is recognised in the income statement except to the extent that it relates to items recognised directly in equity, in which case it is recognised in equity.

Current tax is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted at the balance sheet date, and any adjustment to tax payable in respect of previous years.

Deferred tax is provided using the balance sheet liability method, providing for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. The following temporary differences are not provided for: goodwill not deductible for tax purposes; the initial recognition of assets or liabilities that affect neither the accounting nor the taxable profit; and differences relating to investments in subsidiaries to the extent they will probably not reverse in the foreseeable future. The amount of deferred tax provided is based on the expected manner of realisation or settlement of the carrying amount of assets and liabilities, using tax rates enacted or substantively enacted at the balance sheet date.

A deferred tax asset is recognised only to the extent that it is probable that future taxable profits will be available against which the asset can be utilised. Deferred tax assets are reduced to the extent that it is no longer probable that the related tax benefit will be realised.

Goodwill

All business combinations are accounted for by applying the acquisition method. Goodwill represents amounts arising on acquisition of subsidiaries and businesses. In respect of business combinations that have occurred since 1 January 2004, goodwill represents the difference between the cost of the acquisition and the fair value of the net identifiable assets acquired.

In respect of acquisitions prior to this date, goodwill is included on the basis of its deemed cost, which represents the amount recorded under UK GAAP. The classification and accounting treatment of business combinations that occurred prior to 1 January 2004 were not reconsidered in preparing the Group’s opening IFRS balance sheet at 1 January 2004.

Goodwill is stated at cost less any accumulated impairment losses. Goodwill is allocated to cash-generating units and is no longer amortised but is tested annually for impairment.

Negative goodwill (representing the excess of the fair value of the separable net assets acquired over the fair value of the consideration given) is recognised directly in the income statement.

Revenue

Revenue represents the amounts (excluding value added tax) derived from the provision of colocation and related services to third party customers during the period. Where invoices are raised in advance for colocation services, the revenue is deferred and spread over the period to which it relates. All other revenue, including installation revenue, is recognised in the profit and loss account as agreed milestones are achieved.

Cash And Cash Equivalents

Cash and cash equivalents, for the purpose of the cash flow statement, comprise cash in hand and deposits repayable on demand, less overdrafts payable on demand. Restricted cash is disclosed under debtors.

Impairment

The carrying amounts of the Group’s assets, other than deferred tax assets, are reviewed at each balance sheet date to determine whether there is any indication of impairment. If such an indication of impairment exists, the asset’s recoverable amount is estimated.

For goodwill, the recoverable amount is estimated at each balance sheet date.

An impairment loss is recognised whenever the carrying amount of an asset or its cash-generating unit exceeds its recoverable amount. Impairment losses are recognised in the income statement.

The recoverable amount of the Group’s assets is the greater of their net selling price and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects the current market assessments of the time value of money and the risk specific to the asset. For an asset that does not generate largely independent cash inflows, the recoverable amount is determined for the cash-generating unit to which the asset belongs.

An impairment loss in respect of goodwill is not reversed.

In respect of other assets, an impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortisation, if no impairment had been recognised.

In testing for impairment management has to make judgements and estimations about future events which are uncertain. Adverse results compared to these judgements could alter the decision of whether an impairment is required. See Note 9 for the key assumptions and results of the impairment review carried out in 2006.

Borrowing Costs

Borrowing costs are recognised as an expense in the period in which they are incurred except for borrowing costs relating to the acquisition of a qualifying asset which are capitalised with the cost of the asset. During the year borrowing costs of £Nil (2005: £103k) were capitalised.

Other Financial Liabilities

Other financial liabilities include the following items:

Convertible Debt

The proceeds received on issue of the Group’s convertible debt are allocated into their liability and equity components. The amount initially attributed to the debt component equals the discounted cash flows using a market rate of interest that would be payable on a similar debt instrument that did not include the right to convert. Subsequently the debt component is accounted for as a financial liability measured at amortised cost.

The difference between the debt proceeds of the convertible debt and the amount allocated to the debt component is credited directly to equity and is not subsequently re-measured. On conversion, the debt element is credited to share capital and share premium as appropriate.

Share Option Schemes

Where share options are awarded to employees, the fair value of the options at the date of grant is charged to the income statement over the vesting period. Equity settled share options are recognised with a corresponding credit to equity and cash settled share options are recognised with a corresponding credit to accruals.

Non-market vesting conditions are taken into account by adjusting the number of equity instruments expected to vest at each balance sheet date so that, ultimately, the cumulative amount recognised over the vesting period is based on the number of options that eventually vest. Market vesting conditions are factored into the fair value of the options granted. As long as all other vesting conditions are satisfied, a charge is made irrespective of whether the market vesting conditions are satisfied. The cumulative expense is not adjusted for failure to achieve a market vesting condition. Where the terms and conditions of options are modified before they vest, the increase in the fair value of the options, measured immediately before and after the modification, is also charged to the income statement over the remaining vesting period. Where equity instruments are granted to persons other than employees, the income statement is charged with the fair value of goods and services received.

Intangible Assets

Externally acquired customer contract intangibles are initially recognised at cost on the balance sheet and amortised on a straight line basis over the life of the contract. The life of the intangible assets ranges from 4 months to 3 years.

IPO Costs

Costs relating directly to the issue of new shares are set against share premium. Costs that relate to both new and existing shares are set against share premium in the proportion of new shares issued to total shares listed.

Hedge Accounting

Hedge accounting is applied to financial assets and financial liabilities only where all of the following criteria are met:

The Group does not hold or issue derivative instruments for speculative purposes, although derivatives not meeting the above criteria are designated for accounting purposes at fair value through profit or loss as appropriate.

The Group enters into floating to fixed interest rate swaps. The effective part of these derivatives are measured at fair value with changes in fair value recognised directly to equity. If the Group closes out its position early, the cumulative gains and losses recognised directly in equity are frozen and recycled through the income statement using the effective interest rate method.

Dilapidation Provisions

Dilapidations are provided on leasehold properties where the terms of the lease require the Group to make good any changes made to the property during the period of the lease. Where a dilapidation provision is required the Group recognises an asset and provision equal to the discounted cost of restating the property to its original state. The asset is depreciated over the remaining term of the lease.

2 Segment information

Segment information is presented in respect of the Group’s geographical and business segments. The primary format, geographical segments, is based on the Group’s management and internal reporting structure.

Segment results, assets and liabilities include items directly attributable to a segment as well as those that can be allocated on a reasonable basis. Unallocated items comprise mainly income earning assets and revenue, interest-bearing loans, borrowings and expenses, and corporate assets and expenses.

Geographical Segments

As at 31 December 2006, the Group operated datacentres in four European countries (United Kingdom, France, Germany and Switzerland). It is considered that France, Germany and Switzerland represent regions which are substantially similar and have therefore been combined. Thus, there are two reportable segments, United Kingdom and the Rest of Europe. There is no difference between location of the segment assets and the segment customers.

Business Segments

IX Europe plc has one class of business which is to provide carrier neutral datacentre and related services to its customers.

Amounts within capital expenditure and depreciation include those acquired with subsidiaries and businesses during 2005.

3 Loss from operations

Auditors’ remuneration for services relating to corporate finance transactions entered into in by the Company of £159k above was charged to the income statement in the year as part of IPO costs. £57k was charged to equity, being the portion that related to new shares issued on flotation.

Comparative presentation on the face of the income statement has been changed in order to present a fairer reflection of the results.

(a)—IPO Related Expenses

IPO related expenses totaled £1,582k of which £1,179k was recognised in the income statement.

(b)—Share Option Charges

During the year, the Company granted options to employees under three schemes. The details of the share options granted are set out in Note 13. Share option charges have been separately disclosed to aid understanding as they do not impact the underlying business.

(c)—Negative Goodwill

Negative goodwill was recognised in 2005 on acquisitions where the fair value of assets acquired exceeded the fair value of consideration paid.

4 Financing costs

5 Acquisitions

Gesellschaft für Informationstechnologie mbH

On 5 April 2005, a business continuity provider in Germany was acquired by a Group subsidiary in Germany. All of the voting shares in GIC mbH (Gesellschaft für Informationstechnologie mbH) were acquired for £119k (including costs).

In the 9 months to 31 December 2005 the subsidiary contributed a net loss of £199k to the 2005 consolidated loss of £4,697k. If the acquisition had occurred on 1 January 2005, Group revenue in 2005 would have been £22,696k and 2005 Group loss would have been £4,763k.

Acquirees’s net assets at acquisition date:

The main factors leading to the recognition of goodwill are:

London 3

On 17th November 2005, the assets and business were acquired in West London for £2,450k.

Net assets of business acquired at acquisition date at fair value

Negative goodwill arose due to assets having a fair value higher than was paid.

In the one month to 31 December 2005, the business contributed a net loss of £67k to the 2005 consolidated loss of £4,697k. If the acquisition had occurred on 1 January 2005, Group revenue in 2005 would have been £22,962k and 2005 Group loss would have been £5,438k.

Frankfurt 2

On 29th September 2005, the assets and business were acquired in Frankfurt for £1,284k.

Net assets of business acquired at acquisition date at fair value

Negative goodwill arose due to assets having a fair value higher than was paid.

In the 3 months to 31 December 2005, the business contributed a net profit of £125k to the 2005 consolidated loss of £4,697k. If the acquisition had occurred on 1 January 2005, Group revenue in 2005 would have been £24,078k and 2005 Group loss would have been £4,322k.

No customer related intangibles where recognised as the internal valuations revealed a negative contribution. Negative goodwill has been recognised as a result of the financial distressed position of the acquired businesses prior to the acquisition by IXEurope plc.

Geneva 1

On 25 March 2004 the Group acquired through IX Europe (Switzerland) AG all of the shares of Telehouse (Suisse) SA, Geneva, Switzerland for CHF 1.

The following table sets out the book values of the identifiable assets and liabilities acquired and their fair value to the Group:

The stock acquired was written off due to it being of a non-standard nature and unlikely to be used in the ongoing business.

The estimated useful lives of the fixed assets acquired were adjusted to bring them into line with the Group’s accounting policy.

A provision was made for a lease exit penalty of CHF 3 million upon the acquisition due to renegotiation of the lease of the company’s premises as well as a provision for legal and professional fees of CHF 300,000.

Telehouse (Suisse) SA was merged with IX Europe (Switzerland) AG on 15 June 2004.

In the seven months to 31 December 2004, the business contributed net profit of £43,075 to the consolidated loss of £3,293,338. If the acquisition had occurred on 1 January 2004, Group revenue would have been £15,705,727 and Group loss would have been £3,213,815.

6 Employee expenses

Remuneration Of The Directors

Highest paid Director

At 31 December 2006, 3 Directors (2005: 3; 2004: 3) had retirement benefits accruing under defined contribution pension schemes.

7 Taxation

The tax charge for the year is higher than the standard rate of corporation tax in the UK which is 30% (2005: 30%; 2004: 30%).

The differences are explained below:
