~~Fourth~~First Quarter Results

~~The results discussed below are prepared in accordance with International Financial Reporting Standards and presented in U.S. Generally Accepted Accounting Principles (U.S. GAAP) format.~~ GCUK generated revenue of 78 million pounds, aflat ~~sequential~~sequentially ~~increase of 3 million pounds, or 4 percent,~~ and a year-over-year decrease of ~~4 million~~1 ~~pounds, or 4~~ percent. The sequential increase in revenue was primarily due to increased sales in the company’s “invest and grow” business – that part of the business focused on serving enterprise, carrier and government customers excluding wholesale voice – including an increase in non-recurring fees. The year-over-year decline ~~in revenue~~ was primarily due to ~~the~~a ~~completion~~decrease ~~of the Camelot contract~~ in ~~December~~wholesale ~~2008,~~voice ~~partially offset by growth in other “invest and grow”~~ revenue.

Gross ~~margin~~profit was 2729 million pounds for the quarter, a 41 million pound ~~decrease~~increase sequentially and year over year. ~~Sequentially,~~The ~~gross~~sequential ~~margin~~and year-over-year ~~was~~increase ~~unfavorably impacted by benefits~~ in ~~the~~gross ~~third~~profit ~~quarter~~was ~~from~~principally adue ~~4 million pound favorable regulatory ruling related~~ to ~~access costs~~an ~~paid~~improvement in ~~periods~~revenue ~~prior~~mix towith ~~2009~~lower equipment and aprofessional ~~2 million~~services ~~pound~~costs, ~~non-recurring reduction in property tax charges. The unfavorable sequential impact of these items was~~ partially offset by ~~increased~~an ~~revenue.~~increase ~~The year-over-year decline~~ in ~~gross~~access ~~margin was principally due to lower revenue~~costs.

~~Sales,~~GCUK’s ~~general~~OIBDA ~~and~~for ~~administrative~~the ~~expenses~~first ~~(SG&A)~~quarter ~~were~~was 1120 million pounds ~~for the quarter~~, compared with 1016 million pounds in the ~~prior~~fourth quarter ~~and~~of 142009 and 17 million pounds in the ~~fourth~~first quarter of ~~2008~~2009. The sequential and year-over-year ~~variance~~increases ~~was~~were ~~primarily~~driven ~~due~~by to6 million apounds ~~decrease~~of property tax and insurance recoveries in ~~allocated~~the ~~corporate~~quarter, ~~overhead~~partially ~~costs~~offset by an increase in accrued incentive compensation, salaries and commissions and higher restructuring provisions for real estate.

3GCUK recorded a net loss of 5 million pounds for the first quarter, compared with a net loss of 2 million pounds in both the fourth quarter of 2009 and the first quarter of 2009. The sequential and year-over-year increases in net loss were primarily due to an unfavorable foreign exchange impact on net U.S. dollar-denominated debt.

GCUK’s OIBDA for the fourth quarter was 16 million pounds, compared with 20 million pounds in the third quarter of 2009 and 16 million pounds in the fourth quarter of 2008. The sequential decrease in OIBDA was primarily due to the non-recurring items benefitting gross margin in the third quarter. Year over year, lower gross margin was offset by a decrease in allocated corporate overhead costs.

GCUK recorded a net loss of 2 million pounds for the fourth quarter, compared with a net loss of 2 million pounds in the third quarter of 2009 and a net loss of 25 million pounds in the fourth quarter of 2008. The year-over-year decrease in net loss was primarily due to an unfavorable foreign exchange impact on net U.S. dollar-denominated debt in the year-ago period.

Full Year Results

GCUK generated revenue of 309 million pounds in 2009, compared with 323 million pounds for 2008. The year-over-year decline in revenue was primarily due to the completion of the Camelot contract, which was partially offset by increases in other “invest and grow” revenue.

Gross margin for 2009 was 106 million pounds, or 34 percent of revenue, compared with the prior year in which gross margin was 119 million pounds, or 37 percent of revenue. The year-over-year decline in gross margin was principally due to lower revenue as described above and higher cost of equipment and professional services costs. These movements were somewhat offset by lower cost of access and third party maintenance costs.

SG&A was 40 million pounds for the year, compared with 43 million pounds in the prior year. The year-over-year variance was primarily due to a decrease in allocated corporate overhead costs.

GCUK’s OIBDA for 2009 was 66 million pounds, compared with 76 million pounds in 2008. The year-over-year decline in OIBDA was principally due to lower gross margin due to the factors described above, partially offset by a decrease in allocated corporate overhead costs.

GCUK recorded net income of 5 million pounds for 2009, compared with a net loss of 30 million pounds in 2008. The year-over-year improvement was primarily due to an unfavorable foreign exchange impact on net U.S. dollar-denominated debt in the prior year.

Cash and Liquidity

As of ~~December~~March 31, ~~2009~~2010, GCUK had cash and cash equivalents of 3733 million pounds, compared with 2637 million pounds at the end of ~~September~~December 3031, 2009, and 3633 million pounds at the end of ~~December~~March 31, ~~2008~~2009.

GCUK’s cash and cash equivalents ~~increased~~decreased 114 million pounds in the ~~fourth~~first quarter. Net cash ~~from~~used in operating activities during the ~~fourth~~first quarter totaled 149 million pounds, including cash ~~flow~~use from operating working capital of 1327 million pounds and interest payments of 151 million pounds. During the quarter, GCUK recorded purchases of property, plant and equipment of 35 million pounds, and principal payments on finance leases and other debt of 43 million pounds. ~~and~~In ~~proceeds~~addition, GCUK borrowed 13 million pounds from ~~refinancing~~Global Crossing Europe Limited, a ~~capital~~subsidiary ~~lease~~ of ~~4 million~~Global ~~pounds~~Crossing Limited, for general corporate purposes.

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 will satisfy this requirement by providing the note holders with its quarterly earnings press releases. This schedule of supplemental information is being included with the earnings release to ensure the information being provided complies with Section 4.17(a)(2) of the indenture.

Liquidity and Capital Resources

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 its existing major debt instruments as described below. However, its ability to improve cash flows is subject to the risks and uncertainties, such as the variability of quarterly liquidity, discussed below.

In the short term, GCUK expects cash provided by operating activities to exceed purchases of property and equipment. In addition, its 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 factors noted below.

•

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.

•

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 with 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.

•

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

On March 30, 2010, GCUK entered into a £0.9 million finance lease facility with Huawei Technologies (UK) Co Ltd which was fully drawn down at that time. The lease is subject to an applicable rate of interest of 8% per annum, with payments made over a period of 18 months from April 30, 2010.

On March 31, 2010, GCUK borrowed $20.0 million from Global Crossing Europe Limited (“GCE”), a subsidiary of Global Crossing Limited. The loan matures on September 15, 2013 and accrues interest at 12% per annum, payable semi-annually on March 15 and September 15 of each year.

Schedule 6

Reconciliation of OIBDA to Net (Loss) ~~Income~~

Results below are in pounds sterling in thousands

Pursuant to the SEC'’s Regulation G, the following table provides a reconciliation of OIBDA, which is considered a non-GAAP ~~financial~~(Generally Accepted Accounting Principles) financial measure, to net (loss) ~~income~~ under UIFRS.S. ~~GAAP reporting format.~~

OIBDA is defined as operating ~~income~~profit before depreciation and amortization, ~~based~~and ~~upon~~foreign ~~our~~exchange ~~IFRS~~gains ~~results~~(losses) inon ~~U.S.~~operating ~~GAAP~~working ~~reporting~~capital ~~format~~movements, based upon our consolidated statements of operations. OIBDA differs from operating ~~income~~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, ~~interest~~finance ~~income~~revenue, ~~interest~~ ~~expense~~finance charges, foreign exchange gains (losses) income taxes and other non-operating ~~income~~profit or ~~expense~~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.
