GCUK generated revenue of 7583 million pounds in the fourth quarter, a sequential ~~decrease~~increase of 310 percent and a year-over-year increase of 16 percent. The sequential ~~decrease~~and ~~was~~year-over-year increases were primarily due to ~~lower~~a ~~sales related to short~~non-~~interval~~recurring ~~demand,~~benefit ~~such as purchases~~ of ~~equipment~~4 million ~~and~~pounds ~~professional~~from ~~services,~~the ~~and~~completion ~~somewhat~~of ~~higher~~a ~~sales~~customer ~~credits~~contract ~~after~~and ~~lower~~5 million ~~than~~pounds ~~average~~from ~~sales credits in~~ the ~~prior~~sale ~~quarter.~~of ~~The~~equipment ~~year-over-year~~in ~~increase~~connection ~~was~~with ~~primarily~~a ~~due~~new tocontract ~~increased~~for ~~sales~~managed ~~to enterprise customers~~services.

Full Year Results

GCUK generated revenue of 314 million pounds in 2010, compared with 309 million pounds for 2009. The year-over-year increase in revenue was due to growth in the company’s strategic “Invest and Grow” services including the previously mentioned contract completion and equipment sale, partially offset by declines in wholesale voice revenue.

Gross profit for 2010 was 117 million pounds, or 37 percent of revenue, compared with gross profit of 112 million pounds, or 36 percent of revenue in 2009. The year-over-year increase in gross profit was principally due to margin associated with the previously mentioned contract completion and equipment sale and lower depreciation and amortization in 2010, partially offset by the benefit in 2009 from a favorable regulatory ruling.

GCUK’s OIBDA for 2010 was 70 million pounds, compared with 66 million pounds in 2009. The year-over-year increase in OIBDA was due to higher gross margin.

GCUK recorded net loss of 7 million pounds for 2010, compared with net profit of 5 million pounds in 2009. The year-over-year decrease was primarily due to an unfavorable foreign exchange impact on net U.S. dollar-denominated debt in 2010.

Cash and Liquidity

As of ~~September~~ December 3031, 2010, GCUK had cash and cash equivalents of 4249 million pounds, compared with 3842 million pounds on ~~June~~September 30, 2010, and 2637 million pounds on ~~September~~December 3031, 2009.

Schedule 5

SUPPLEMENTAL INFORMATION PROVIDED PURSUANT TO THE INDENTURE GOVERNING THE GCUK SENIOR SECURED

NOTES

GCUK is required to provide the holders of its Senior Secured Notes due 2014 with quarterly information pursuant to Section 4.17(a)(2) of the indenture governing such notes. For quarters prior to the first quarter of 2010, GCUK satisfied this requirement by providing the note holders with a quarterly report separate and apart from its quarterly earnings press releases. Starting with the first quarter of 2010, GCUK has satisfied this requirement by providing the note holders with its quarterly earnings press releases. This schedule of supplemental information is being included with the earnings press release to ensure that the information being provided complies with Section 4.17(a)(2) of the indenture.

Liquidity and Capital Resources

GCUK’s ability to make payments on and to refinance its indebtedness and to fund planned capital expenditures will depend on its ability to generate cash in the future. This depends to a degree on general economic, financial, competitive, legislative, regulatory and other factors that are beyond GCUK’s control.

GCUK monitors its capital structure on an ongoing basis and from time to time considers financing and refinancing options to improve its capital structure and to enhance its financial flexibility. GCUK’s ability to enter into new financing arrangements is subject to restrictions in its outstanding debt instruments. At any given time GCUK may pursue a variety of financing opportunities, and its decision to proceed with any financing will depend, among other things, on prevailing market conditions, near term maturities and available terms. In addition, from time to time GCUK reviews its operations and may consider opportunities to strategically enhance, expand or change its operations and leverage its capabilities. If GCUK pursues any such opportunities, it may require additional equity or debt financing, and there can be no assurance that it will be able to obtain such financing on favorable terms or at all. Undertaking any such initiatives may place greater demands on GCUK’s cash flows due to increased capital and operating expenses and debt service.

At September 30, 2010, GCUKs available liquidity consisted of £42.2 million of unrestricted cash and cash equivalents.

In the long term, GCUK expects its operating results and cash flows to improve as a result of growth of its revenues, including the economies of scale expected to result from such growth, and from ongoing cost management initiatives, including initiatives to optimize the access network and effectively lower unit prices. Thus, in the long term, GCUK expects to generate positive cash flow from operating activities in an amount sufficient to fund all investing and financing requirements, subject to the need to refinance the GCUK Senior Secured Notes. However, its ability to improve cash flows is subject to the risks and uncertainties, such as the variability of quarterly cash flows, discussed below.

In the short term, GCUK expects cash provided by operating activities to exceed purchases of property and equipment. This expectation is based in part on the raising of financing for certain property and equipment from vendors and other third parties. Its ability to arrange such financings is subject to negotiating acceptable terms from equipment vendors and financing parties. In addition, GCUK’s short term liquidity and more specifically its quarterly cash flows are subject to considerable variability as a result of the timing of interest payments as well as the following factors.

• Working capital variability significantly impacts its cash flows and can cause its intra-quarter cash balances to drop to levels significantly lower than those levels prevailing at the end of a quarter.

• Adverse general economic conditions could cause customer buying patterns with GCUK to change as a result of their cash conservation efforts, which could have an adverse impact on its cash flows. Such adverse conditions could also adversely impact its working capital to the extent suppliers seek more timely payment from GCUK or customers pay GCUK on a less timely basis.

• The UK government has announced austerity measures aimed at reducing costs in a wide range of areas, including telecommunications. The implementation of pricing actions and the reduction of spending by governmental entities could have a negative effect on GCUK’s future revenue performance.

• Within 120 days after each calendar year, GCUK must offer to purchase a portion of the Senior Secured Notes at 100% of their principal amount using 50% of the Operating Cash Flow (as defined in the Indenture) for that year. In respect of 2009, it offered to purchase £11.8 million of the Notes, excluding accrued interest and purchased £0.2 million of the Notes, plus accrued interest through the purchase date. If the current year to date results were the results for the full year to December 31, 2010, the Company would be obliged to make an Annual Repurchase Offer of approximately £5.9 million, exclusive of accrued but unpaid interest.

GCUK’s Senior Secured Notes (less any amounts purchased as a result of any excess cash offer) mature in 2014. If cash on hand at the time these debt instruments mature is insufficient to satisfy these and GCUK’s other debt repayment obligations, GCUK could need to access the capital markets to meet its liquidity requirements. Such access would depend on market conditions and its credit profile at the time.

• GCUK’s liquidity may also be adversely affected if it is found liable in respect of contingent legal, tax and other liabilities. The amount and timing of the resolution of these contingencies remain uncertain.

Financing activities

There were no significant financing activities during the quarter.

Commitments

During the quarter the Company entered into an agreement with Siemens for the purchase of hardware and software licences, together with an ongoing equipment rental charge The minimum commitment is £15.3 million payable between now and September 2011.

In November 2010, the Company entered in a ten year lease, break clause after five years, for London office space with a minimum commitment of £3.9 million.

Taxation

The UK Government announced on June 22, 2010 there will be a reduction of the corporation tax rate from 28% to 24% over four years beginning on April 1, 2011. On July 27, 2010 the Government fully enacted the first stage of the process by reducing the tax rate from 28% to 27% with effect from April 1, 2011.

Other

The GCUK sales organization has been supplemented in the last 12 months, although the additional resources have not yet resulted in appreciable revenue growth. In the third quarter of 2010, GCUK experienced some softness in short-interval demand related to purchases of equipment and professional services and also experienced an increase in sales credits. The UK market continues to be highly competitive with significant pricing pressure, and we expect that competitive environment to continue.

One of our principal customer relationships is with the Foreign & Commonwealth Office (“FCO”), to whom we provide an international telecommunications network known as the FTN. Our contract to provide the FTN expired in May 2010. We have entered into transition arrangements in respect of the FCO’s migration to a network to be provided by a competitor as the replacement for the FTN. We do not expect this to have a significant impact on our 2010 results and estimate our 2011 revenue to be adversely impacted by between £6 million to £10 million. In addition, we continue to pursue other ordinary course commercial opportunities with the FCO.

Subsequent to the quarter end, we entered into two new agreements relating to services for existing customers. The first of these is with Network Rail under which we will provide voice and data services for an additional three years. Second, on the completion of a prior agreement to provide telephony and other services to Her Majesty’s Revenue & Customs (“HMRC”), we entered into a new deal with a systems integrator partner to provide managed hosted IP telephony and contact center services to HMRC for a further five years.

Schedule 6

Global Crossing (UK) Telecommunications Limited and Subsidiaries

Reconciliation of ~~OIBDA to~~ Net ~~Profit/~~(Loss) Profit to OIBDA

Results below are in pounds sterling in thousands

Pursuant to the SEC’s Regulation G, the following table provides a reconciliation of net (loss)/profit under IFRS to OIBDA, which is considered a non-GAAP (Generally Accepted Accounting Principles) financial measure~~, to net profit/(loss)under IFRS~~.

OIBDA is defined as operating profit before depreciation and amortization and foreign exchange ~~gains/~~(losses) gains on operating working capital movements, based upon our consolidated statements of operations. OIBDA differs from operating profit, in that it excludes depreciation and amortization. Such excluded expenses primarily reflect the non-cash impacts of historical capital investments, as opposed to the cash impacts of capital expenditures made in recent periods. In addition, OIBDA does not give effect to cash used for debt service requirements and thus does not reflect available funds for reinvestment, distributions or other discretionary uses.

Management uses OIBDA as an important part of our internal reporting and planning processes and as a key measure to evaluate profitability and operating performance, make comparisons between periods, and to make resource allocation decisions. Management believes that the investment community uses similar performance measures to compare performance of competitors in our industry.

There are material limitations to using non-GAAP financial measures. Our calculation of OIBDA may differ from similarly titled measures used by other companies, and may not be comparable to those other measures. Additionally, OIBDA does not include certain significant items such as depreciation and amortization, finance revenue, finance charges, foreign exchange ~~gains/~~(losses) gains, income taxes and other non-operating profit or loss items. OIBDA should be considered in addition to, and not as a substitute for, other measures of financial performance reported in accordance with GAAP.

Management believes that OIBDA is useful to our investors as it is a relevant indicator of operating performance, especially in a capital-intensive industry such as telecommunications. OIBDA provides investors with an indication of the underlying performance of our everyday business operations. It excludes the effect of items associated with our capitalization and tax structures, such as interest income, interest expense and income taxes, and of other items not associated with our everyday operations.
