PART I
ITEM 1.E

                          FLAG TELECOM HOLDINGS LIMITED
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        AS OF SEPTEMBER 30, 2000 AND 1999

1.       GENERAL

         The interim consolidated financial statements presented herein have
         been prepared on the basis of U.S. generally accepted accounting
         principles and include the accounts and balances of FLAG Telecom
         Holdings Limited ("FLAG Telecom" or the "Company") and its
         wholly-owned subsidiaries. All significant intercompany transactions
         have been eliminated in consolidation. In the opinion of management,
         the unaudited consolidated financial statements reflect all adjustments
         (consisting of normal recurring accruals) necessary for a fair
         presentation of the results of operations for the three months and nine
         months ended September 30, 2000, the nine months ended September 30,
         1999, the period from incorporation to September 30, 1999 and the
         period from January 1, 1999 to February 26, 1999, (FLAG Limited), the
         balance sheets as of September 30, 2000, and December 31, 1999, and the
         cash flows for the nine months ended September 30, 2000, the period
         from incorporation to September 30, 1999, and the period from January
         1, 1999, to February 26, 1999, (FLAG Limited). Our interim consolidated
         financial statements should be read in conjunction with our audited
         consolidated financial statements for the year ended December 31, 1999.
         The results of operations for any interim period are not necessarily
         indicative of results for the full year.

         FLAG Telecom was incorporated on February 3, 1999 to serve as the
         holding company for the FLAG Telecom group of companies (the
         "Group"). On February 26, 1999 FLAG Telecom acquired approximately
         65.79% of FLAG Limited by exchanging 69,709,935 shares of FLAG
         Limited common stock for the same number of shares of FLAG Telecom
         common stock. The minority shareholder of FLAG Limited exchanged its
         remaining holdings in FLAG Limited for shares in FLAG Telecom on
         January 4, 2000 such that on that date FLAG Limited became a wholly
         owned subsidiary of FLAG Telecom. This acquisition has been
         accounted for as a recapitalisation such that no goodwill arises and
         assets and liabilities are reflected at their carryover basis.

         The results of the operations of FLAG Limited have been included in the
         consolidated results of FLAG Telecom's operations since the date of
         acquisition.

2.       REVENUE RECOGNITION

         Capacity contracts are accounted for as leases. For contracts that
         satisfy sales type lease accounting, revenues are recognized upon the
         date the risks and rewards of ownership are transferred to the
         purchaser, which is the date the capacity is made available for
         activation and the customer becomes responsible for maintenance
         charges. As a result of the issuance of FASB Interpretation No. 43,
         with effect from July 1, 1999, certain sales of capacity may no longer
         be recognized as current revenue because they do not satisfy the
         requirements for sales-type lease accounting. Revenues from these
         capacity sales are now deferred and




                                       5
<PAGE>

         amortized over the term of the contracts. The change to the accounting
         treatment has no impact on cash flows. Until June 30, 1999 revenues
         from operating lease transactions were considered incidental and
         recorded as a reduction of the capacity available for sale.

3.       CAPACITY AVAILABLE FOR SALE

         Historically, capacity for sale has been recorded at the lower of cost
         or fair value less cost to sell and charged to cost of sales as
         capacity is sold. Until contracts were entered into that precluded
         sales-type lease accounting for a particular segment, the cost of such
         segment remained in capacity available for sale.

         As a result of extending the range of products and services offered by
         FLAG Telecom, the greater part of future revenue is expected to arise
         under agreements that will be accounted for as operating leases or
         service contracts and will require the recognition of revenues over the
         relevant term of the agreements. The remaining cost of the FLAG Telecom
         Network has therefore been reclassified from capacity available for
         sale to fixed assets on January 1, 2000. This cost will be depreciated
         over the remaining estimated economic life of the system.

4.       EQUITY ISSUE

         Direct third party costs incurred as a result of the issuance of equity
         are offset against the proceeds from the issue and debited against
         additional paid in capital.

5.       DEBT ISSUE

         New debt issues are recorded net of any discount on the offering.
         Direct third party costs incurred during an issuance are capitalized
         and classified as non current assets. Capitalized costs and discounts
         are amortized as an adjustment to interest expense over the lives of
         the relevant instruments.

6.       DEBT MODIFICATION

         Fees paid to the lender as a result of a credit facility amendment are
         offset against the modified debt instrument and amortized as an
         adjustment to interest expense over the remaining term of the modified
         debt instrument along with any existing unamortized premium or
         discount.

7.       CONTINGENCIES

         The Company is involved in litigation from time to time in the ordinary
         course of business. In management's opinion, the litigation in which
         the Company is currently involved, individually and in the aggregate,
         is not material to it.


8.       NET INCOME\(LOSS) PER COMMON SHARE

         Basic net income\(loss) per common share is computed by dividing


                                        6
<PAGE>

         net income \ (loss) applicable to common shareholders by the weighted
         average number of common shares outstanding in the period. Diluted net
         income \ (loss) per common share is computed by dividing net income \
         (loss) by the weighted average number of common shares and common share
         equivalents outstanding during the period. For the three and nine month
         periods ended September 30, 2000 presented, no potentially dilutive
         securities have been included in the calculation of diluted net loss
         per share amounts as they would be antidilutive in periods in which a
         loss has been reported. The aggregate number of potential common share
         equivalents that have been excluded from the diluted net loss per share
         calculation was 1,607,066 and 1,674,845 for the three and nine month
         periods ended September 30, 2000, respectively, and related entirely to
         stock options.

9.       SEGMENTAL INFORMATION

         The Company has prepared segmental information using accounting
         policies that are consistent across segments.

         On a segmental basis, FLAG Telecom reports its results in its two
         primary operational areas: Capacity Sales and Operations and Network
         Services. The Network Services business now makes a material and
         growing contribution to the Company's revenue. The segments include
         revenues from the various types of products and services as noted:

         Capacity Sales and             Traditional carrier services, involving
         Operations                     dispositions of capacity by sale, right
                                        of use or lease

                                        Operations and maintenance
                                        revenues

         Network Services               Managed bandwidth services

                                        Leased capacity services

                                        IP point to point services

                                        IP transit services

                                        Other value added and related services


         Details of the financial results of the two business segments for the
         nine months ended September 30, 2000 are summarized below reconciled to
         the totals for the Group as a whole. Substantially all the revenues and
         operating results in earlier periods arose from Capacity Sales and
         Operations.

         On February 16, 2000, FLAG Telecom completed an initial public offering
         of its common shares. Approximately $633.8 million net proceeds were
         received from that offering. On March 17, 2000, FLAG Telecom completed
         a private placement of 300 million dollar denominated and 300 million
         Euro denominated 11 5/8% Senior Notes due 2010. Approximately $576
         million net proceeds were received from that offering.

         On February 16, 2000, FLAG Limited amended its existing credit
         facilities to consist of a $150 million six-year term loan facility
         ($125 million of which is outstanding) and a $10 million revolving
         credit facility (none of which is outstanding).

         The undersea survey for the FLAG Pacific-1 (FP-1) cable system is
         ongoing. Upon completion of FP-1, scheduled for 2002, the
         multi-terabit dual cable system will link the major internet hub
         cities of Seattle, Vancouver, San Francisco, Los Angeles and Tokyo.
         With FP-1, the FLAG Telecom network will extend over 64,500 kilometer
         route.

         FLAG Atlantic-1 remains on schedule to enter service in the first
         quarter of 2001. All the permits at the landing sites have been
         obtained. One landing station in the USA is currently under
         construction and is expected to be completed by year end. All other
         landing stations are completed. The shore-end cables have been
         successfully landed in the UK, France and the US and marine
         installation activity across the Atlantic has begun.

         FLAG Europe-Asia had made over $900 million sales to over 100 customers
         worldwide as at 30 September 2000. The average fill rate across the
         route was some 25% with substantially higher rates at the Western end
         and over the Hong Kong to Japan leg.

11.      PENDING ACCOUNTING STANDARDS

         The Financial Accounting Standards Board has issued Statement of
         Financial Accounting Standard No. 133, "Accounting for Derivative
         Instruments and Hedging Activities" (SFAS 133) and Statement of
         Financial Accounting Standard No. 138, "Accounting for Certain
         Derivative Instruments and Certain Hedging Activities - an Amendment of
         FASB Statement No. 133" (SFAS 138). Following the amendment made by
         SFAS No. 137, SFAS 133 and SFAS 138 is effective for periods beginning
         after June 15, 2000. Management is currently assessing the impact of
         the adoption of SFAS 133 and SFAS 138 on the Company's financial
         position and results of operations, which may be material.

         In December 1999, the Securities and Exchange Commission (SEC) issued
         Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial
         Statements" (SAB 101). SAB 101 outlines the SEC's views on applying
         generally accepted accounting principles to revenue recognition in
         financial statements. Specifically, the bulletin provides both general
         and specific guidance as to the periods in which companies should
         recognize revenues. In addition, SAB 101 also highlights factors to be
         considered when determining whether to recognize revenues on a gross or
         net basis. SAB 101, as amended by SAB 101/A and SAB 101/B, is effective
         beginning no later than their fourth fiscal quarter of the fiscal year
         beginning after December 15, 1999; as the Group is a calendar year-end
         company, this would be the quarter ending December 31, 2000. The Group
         believes that its policies in regards to the recognition of revenues
         are in compliance with the guidance of SAB 101 and does not expect that
         the adoption of this standard will have any material effect on its
         results of operations, cash flows or financial position.

         The Emerging Issues Task Force (EITF) has recently issued EITF 00-2
         ("Accounting For Web Site Development Costs") . The EITF has
         reached a consensus that all costs associated with the planning of web
         site development projects should be expensed as incurred, while costs
         incurred in the application and development stage should generally be
         capitalized in accordance with American Institute of Certified Public
         Accountants Statement of Position 98-1, "Accounting for the Costs of
         Computer Software Developed or Obtained for Internal Use", or other
         relevant pronouncements. Costs incurred in the operations of the web
         site are generally expensed as incurred. The EITF has not yet reached a
         consensus as to the accounting for the costs of developing and
         displaying content or other information on a web site, but the EITF
         plans further discussion on this issue. EITF 00-2 is effective
         for web site development costs incurred for fiscal quarters beginning
         after June 30, 2000. As the Company's current policy is substantially
         consistent with the consensuses reached in EITF 00-2, the Company does
         not expect that the issuance of this pronouncement will have a material
         effect on its financial condition or results of operations.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

PART I
ITEM 2

QUARTER ENDED SEPTEMBER 30, 2000 COMPARED WITH THE QUARTER ENDED SEPTEMBER 30,
1999

RESULTS OF OPERATIONS

REVENUES

Total revenue recognized by the Company during the quarter ended September 30,
2000, was $27.3 million compared to $53.9 million total revenue for the quarter
ended September 30, 1999.

Revenue recognized from the sale of capacity was $11.4 million for the quarter
ended September 30, 2000 compared to $46.1 million during the quarter ended
September 30, 1999. As a result of the issuance of FASB Interpretation No. 43,
with effect from July 1, 1999, certain sales of capacity may no longer be
recognized as current revenue because they do not satisfy the requirements for
sales-type lease accounting. Revenues from these capacity sales are now deferred
and amortized over the term of the contracts. The change to the accounting
treatment has no impact on cash flows.

As of September 30, 2000, the Company had entered into sales transactions with
in excess of 100 international telecommunication carriers, compared to 90 as of
September 30, 1999.

Revenue recognized from operations and maintenance was $10.2 million for the
quarter ended September 30, 2000 compared to $7.8 million for the quarter ended
September 30, 1999, reflecting the increased cumulative sales on the FLAG
Telecom Network.

Revenue recognized from Network Services was $5.7 million for the quarter ended
September 30, 2000. No Network Services revenue was generated for the quarter
ended September 30, 1999.

OPERATING EXPENSES

For the quarter ended September 30, 2000 the Company recorded $19.6 million in
respect of depreciation compared to $23.3 million for depreciation and cost of
capacity sold recorded in the quarter ended September 30, 1999. The adoption of
FASB Interpretation No. 43 discussed above has meant that the remaining capacity
available for sale has been reclassified to fixed assets on January 1, 2000 and
is being depreciated over the remaining economic life of the network, rather
than being written off as cost of sales.

During the quarter ended September 30, 2000 the Company incurred $4.7 million in
network services costs. No network services costs were incurred for the quarter
ended September 30, 1999. These costs relate primarily to local backhaul,
connection and restoration costs.

During the quarter ended September 30, 2000 the Company incurred $7.6 million in




                                       10
<PAGE>

operations and maintenance costs compared to $6.3 million for the quarter ended
September 30, 1999. Operations and maintenance costs relate primarily to the
provision of standby maintenance under Maintenance Zone Agreements as well as
salaries and overheads directly associated with operations and maintenance
activities. The increase is primarily due to additional costs arising from
increased activity plus increased use of contracted services.

During the quarter ended September 30, 2000, $3.6 million in sales and marketing
costs were incurred compared to $4.4 million incurred during the quarter ended
September 30, 1999. Sales and marketing costs are comprised of all sales and
marketing activities that are directly undertaken by the Group. The decrease in
sales and marketing costs in the quarter ended September 30, 2000 over the
quarter ended September 30, 1999 relates to certain one off commission payments
in respect of sales made last year.

During the quarter ended September 30, 2000, $9.9 million of general and
administrative expenses were incurred compared to $6.7 million during the
quarter ended September 30, 1999. Increases are primarily due to non-cash stock
compensation costs incurred plus additional staff and office related costs.

Costs for the quarter ended September 30, 2000 include charges for non-cash
stock compensation expense of $1.3 million in respect of certain awards under
our long term incentive plan. These charges are required under US accounting
standards and are purely accounting charges having no effect on cash flows.

INTEREST EXPENSE AND INTEREST INCOME

Interest expense on borrowings increased from $13.5 million for the quarter
ended September 30, 1999 to $28.3 million for the quarter ended September 30,
2000. The increase in interest expense of $14.8 million is attributable to
additional borrowings obtained. See also "Liquidity and Capital Resources."

The foreign exchange gain of $16.5 million arises from the translation at the
quarter end of the Net Euro denominated borrowings from Euros to US dollars at
the balance sheet exchange rate.

Interest income of $21.7 million was earned during the quarter ended
September 30, 2000 compared to $2.1 million earned during the quarter ended
September 30, 1999. The interest income was earned on cash balances, short
term investments and cash held by the Collateral Trustee or in escrow arising
from ongoing business operations. These amounts have increased significantly
due to proceeds received from the initial public offering of our shares and
further borrowings, including the issuance of our Senior Notes, which are
currently held on deposit.

PROVISION FOR TAXES

The provision for taxes was $0.2 million for the quarter ended September 30,
2000 compared to $0.6 million for the quarter ended September 30, 1999. The tax
provisions for periods consists both of taxes on income derived from capacity
sales and standby maintenance revenue from customers in certain jurisdictions
along the FLAG Telecom Network where the Group is deemed to have a taxable
presence or is otherwise subject to tax, and taxes on the activities of group
undertakings in certain locations. At the present time, no income, profit,
capital or capital gains taxes are levied in Bermuda. In the event that such
taxes are levied, the Group of companies incorporated in Bermuda




                                       11
<PAGE>

received an undertaking from the Bermuda Government exempting it from all such
taxes until March 28, 2016.

NET LOSS AND LOSS PER COMMON SHARE

For the quarter ended September 30, 2000 the Company recorded a net loss of $7.1
million compared to a net loss of $0.5 million for the quarter ended September
30, 1999. This is attributable primarily to reduced accounting revenue and
increased depreciation costs caused by the adoption of FASB Interpretation No.
43 with effect from July 1, 1999.

Basic and diluted loss per common share was $0.05 for the quarter ended
September 30, 2000 compared to basic and diluted loss per common share of $0.01
for the quarter ended September 30, 1999.

During the nine months ended September 30, 2000 the Company incurred $8.3
million in network services costs. No network services costs were incurred for
the nine months ended September 30, 1999. These costs relate primarily to local
backhaul, connection and restoration costs.

During the nine months ended September 30, 2000 the company incurred $24.6
million in operations and maintenance costs compared to $21.3 million for the
nine months ended September 30, 1999. Operations and maintenance costs relate
primarily to the provision of standby maintenance under Maintenance Zone
Agreements as well as salaries and overheads directly associated with operations
and maintenance activities. The increase is primarily due to additional costs
arising from increased activity plus increased use of contracted services.

During the nine months ended September 30, 2000, $9.9 million in sales and
marketing costs were incurred compared to $8.0 million incurred during the nine
months ended September 30, 1999. Sales and marketing costs are comprised of all
sales and marketing activities that are directly undertaken by the Group. The
increase in sales and marketing costs in the nine months ended September 30,
2000 over the nine months ended September 30, 1999 is due to the greater
employment and related costs associated with the increased world-wide sales and
marketing activity and non-cash stock compensation costs.

During the nine months ended September 30, 2000, $27.6 million of general and
administrative expenses were incurred compared to $17.6 million during the nine
months ended September 30, 1999. Increases are primarily due to non-cash stock
compensation costs incurred plus additional staff and office related costs.

Costs for the nine months ended September 30, 2000 includes charges for non-cash
stock compensation expense of $5.9 million in respect of certain awards under
our long term incentive plan. These charges are required under US accounting
standards and are purely accounting charges having no effect on cash flows.

INTEREST EXPENSE AND INTEREST INCOME

Interest expense on borrowings increased from $41.0 million for the 9 months
ended September 30, 1999 to $74.4 million for the nine months ended September
30, 2000. The increase in interest expense of $33.4 million is attributable to
additional borrowings obtained. See also "Liquidity and Capital Resources."

The foreign exchange gain of $18.9 million arises from the translation at the
period end of the Net Euro denominated borrowings from Euros to US dollars at
the balance sheet exchange rate.

Interest income of $48.9 million was earned during the nine months ended
September 30, 2000 compared to $6.7 million earned during the nine months ended
September 30, 1999. Interest was earned on cash balances and short term
investments and cash held by the Collateral Trustee (with respect to FLAG
Limited's 8 1/4% Senior Notes) or in escrow arising from ongoing business
operations. These amounts have increased significantly due to proceeds received
from the initial public offering of our shares and further borrowings, including
the issuance of our Senior Notes, which are currently held on deposit.

PROVISION FOR TAXES

The provision for taxes was $0.9 million for the nine months ended September 30,
2000 compared to $1.3 million for the nine months ended September 30, 1999. The
tax provisions for periods consists both of taxes on income derived from

sales and standby maintenance revenue from customers in certain jurisdictions
along the FLAG Telecom Network where the Group is deemed to have a taxable
presence or is otherwise subject to tax, and taxes on the activities of group
undertakings in certain locations. At the present time, no income, profit,
capital or capital gains taxes are levied in Bermuda. In the event that such
taxes are levied, the Group of companies incorporated in Bermuda received an
undertaking from the Bermuda Government exempting it from all such taxes until
March 28, 2016.

NET (LOSS) / INCOME AND (LOSS) / INCOME PER COMMON SHARE

For the nine months ended September 30, 2000 the Company recorded a net loss of
$(63.0) million compared to net income of $6.1 million for the nine months ended
September 30, 1999. This is attributable primarily to reduced accounting revenue
and increased depreciation costs caused by the adoption of FASB Interpretation
No. 43 with effect from July 1, 1999.

Basic and diluted loss per common share was $(0.49) for the nine months ended
September 30, 2000 compared to an income per common share of $0.09 (including
minority interest) for the nine months ended September 30, 1999.

LIQUIDITY AND CAPITAL RESOURCES

We have financed our operations to date through a combination of equity
contributions, bank debt, the proceeds of debt offerings, and the proceeds of an
initial public offering of our common shares.

On February 16, 2000, we completed an initial public offering (IPO) of our
common shares. We received $633.8 million in net proceeds from that offering.
On March 17, 2000 we completed the issue of 11 5/8% Senior Notes in the US
and Europe, raising net proceeds of $576.6 million.

On February 16, 2000, FLAG Limited amended its existing credit facilities to
consist of a $150 million six-year term loan facility ($125 million of which
remained outstanding at September 30, 2000) and a $10 million revolving credit
facility (none of which is outstanding). Dresdner Kleinwort Benson and Barclays
Capital acted as joint lead arrangers. These facilities bear interest at a rate
of 225 basis points over LIBOR for the first six months and thereafter at a rate
of between 150 and 250 basis points over LIBOR, depending on the credit rating
of the 8 1/4% Senior Notes of FLAG Limited. The current interest rate is 200
basis points over LIBOR. The facilities are secured by a pledge by us of all of
the capital stock of FLAG Limited and by assignment of FLAG Limited's contracts
and a security interest in its bank accounts and intangible property. In
connection with this amendment, FLAG Limited paid fees and expenses to the joint
lead arrangers totaling approximately $3.3 million.

At the end of March 1998, we entered into two interest rate swap agreements to
manage our exposure to interest rate fluctuations on FLAG Limited's credit
facilities. Under the swap agreements, we paid a fixed rate of 5.6% on a
notional amount of $60 million and a fixed rate of 5.79% on a notional amount of
$100 million and the swap counterparty paid the floating rate based on LIBOR.
One swap agreement terminated in January 2000 and the other swap agreement
terminated in July 2000. In August 2000 we entered into an interest rate collar
transaction for an initial notional amount of $60 million, reducing in
increments to $20 million up to April 2002. The transaction terminates on
April 30, 2002. The collar is comprised of a LIBOR cap at 8% and a floor of
5.85%. We recognize the net cash amount received or paid on interest rate
hedging instruments as an adjustment to interest cost on the related debt.

On October 31, 2000 we announced that we had agreed to buy from GTS its
interest in FLAG Atlantic Limited (FLAG Atlantic), the 50/50 joint venture
that is building the FLAG Atlantic-1 (FA-1) system. On completion, FLAG
Atlantic will become a wholly-owned subsidiary of FLAG Telecom.

Under the terms of the agreement, GTS will receive $135 million in cash from
FLAG Telecom. In addition, GTS will receive additional duct and dark fibre
assets in France and will retain the right to acquire backhaul fibres,
wavelengths and/or duct space from FLAG Atlantic on favourable terms going
forward. GTS's fibre pair purchased on the system, with a total design
capacity of 400 Gbps, will now have an initial lit capacity of 80 Gbps (8 x
10 Gbps).

The transaction will have no impact on either the project's scheduled first
quarter 2001 Ready For Service (RFS) date or on the project's budget. Funding
arrangements for the project, including all pre-sale proceeds of $800 million,
are likewise unaffected.

FLAG Atlantic Limited has a $575 million construction/term loan facility and a
$25 million revolving credit facility. These facilities have a term of 7.5 years
and bear interest at LIBOR plus 125 basis points for that portion of the loans
(not to exceed 50% of the outstanding loans) which are backed by investment
grade receivables and LIBOR plus 300 basis points for the balance of the loans.
The current interest rate is 212.5 basis points over LIBOR.



                                       17
<PAGE>

FLAG Atlantic Limited has elected to cancel $55.174 million of the un-drawn
construction / term loan facility as a result of payments from capacity
pre-sales.

Commitment fees accrue on the undrawn balance of the loans at between 37.5 basis
points and 75 basis points.

FLAG Atlantic Limited's bank facility is secured by an assignment of all of FLAG
Atlantic Limited's assets, a pledge of all of the stock in FLAG Atlantic Limited
and a commitment by each of its shareholders to contribute $100 million in
equity. Such contributions were made on October 31.

The undersea survey for the FLAG PACIFIC-1 (FP-1) cable system has begun. Upon
completion of FP-1, scheduled for 2002, the multi-terabit dual cable system will
link the hub internet cities of Seattle, Vancouver, San Francisco, Los Angeles
and Tokyo. We expect to fund the costs required to complete the project from
some of the proceeds from our IPO and the proceeds from our 11 5/8% Senior Notes
offering and other debt financings and pre-sales.

As of September 30, 2000 and December 31, 1999, the Company had a working
capital surplus of $1,004.5 million and a deficit of $53.7 million respectively.
The working capital deficit was primarily a result of the current accounts
payable to the contractors which is classified as a current liability but for
which the associated funds held in escrow are classified as a non-current asset
and are hence excluded from the measure of working capital.

Total cash provided by operating activities and used in investing activities
during the nine months ended September 30, 2000 was $144.6 million and $(52.8)
million respectively. As of September 30, 2000, cash on deposit, or with the
collateral trustee or in escrow had increased to $1,346.2 million from $137.3
million at December 31, 1999, primarily as a result of the additional funds
obtained from the IPO of $633.8 million and from the 11 5/8% Senior Notes
offering of $576.6 million.

Total cash provided by operating activities and used in investing activities
during the nine months ended September 30, 1999 was $39.0 million and $(102.0)
million respectively.

ASSETS

Our major asset is the remaining capital cost of the FLAG Telecom Network
recorded in fixed assets totalling $1,053.2 million.

As a result of the application of FASB Interpretation No. 43, the costs of
certain segments of the FLAG Telecom Network were reclassified at July 1, 1999
and during the six months ended December 31, 1999 from capacity available for
sale to fixed assets and are being depreciated over their remaining useful life.

As a result of extending our range of products and services, we expect the
greater part of our future revenue to be under agreements that will be accounted
for as operating leases or service contracts and will require us to recognize
revenues over the relevant terms of the agreements. We have therefore
reclassified the remaining cost of the FLAG Telecom Network from capacity
available for sale to fixed assets in the first quarter of 2000. This cost will
be depreciated over the remaining estimated economic life of the system.



                                       18
<PAGE>

Our other fixed assets consist primarily of office furniture, leasehold
improvements, computer equipment and motor vehicles totaling $7.6 million.


ACCOUNTS RECEIVABLE

The accounts receivable balance at September 30, 2000 includes $44.3 million,
which relates to sales contracts booked into deferred revenue but which are
payable in accordance with agreed payment schedules over periods up to one
year. The comparable figure at December 31, 1999 was $49.9 million.


IMPACT OF THE EURO

On January 1, 1999, eleven of the 15 member countries of the European Union,
including France, Germany, Ireland, Italy and Spain, where the Group has
operations, established fixed conversion rates between their existing
sovereign currencies and a new currency called the Euro. These countries
adopted the Euro as their common legal currency on that date. The Euro trades
on currency exchanges and is available for non-cash transactions. Hereafter
and until January 1, 2002, the existing sovereign currencies will remain
legal tender in these countries. On January 1, 2002, the Euro is scheduled to
replace the sovereign legal currencies of these countries.

The Group has operations within the European Union including many of the
countries that have adopted the Euro. The Group continues to evaluate the impact
the Euro will have on its continuing business operations within the overall
scope of managing currency risk. However, the Group does not expect the
introduction of the Euro to have a material effect on the Group's financial
position or competitive position.


OTHER INFORMATION

The interpretation and application of FASB Interpretation No. 43 and also the
accounting for sales of capacity are evolving within the telecom industry. A
number of questions and issues are being taken to the accounting standard
setting boards and different accounting treatments may ultimately be approved,
which may change the timing and methods of the recognition of revenues and the
related costs. We do not, however, anticipate any impact on our current
accounting treatment or that there will be an impact on our cash flows.

PART I
ITEM 3:  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Currency Risk.

The value of the liability of the Euro300 million of 11 5/8% Senior Notes, as
expressed in U.S. dollars on our Balance Sheet, is dependent on the U.S.
dollar/Euro exchange rate at each balance sheet date. The change in this
liability over a period is reflected in our Income Statement in accordance
with U.S. generally accepted accounting principles. In this respect we are
exposed to changes in the value of the Euro against the US dollar. Management
is monitoring this exposure and may hedge the exposure if considered
appropriate.

Other than this, we do not believe that we are exposed to significant risk from
movements in foreign currency exchange rates. All revenues from the disposition
of capacity and billings of standby maintenance and restoration services are
payable in U.S. dollars. All contracts for the provision by third parties of
restoration are invoiced to us in U.S. dollars. Some contracts for the provision
of FLAG Network Services are payable in currencies other than U.S. dollars. Some
vendor contracts for the provision to the FLAG Europe-Asia cable system of
operations and maintenance services and local operating expenses of our
subsidiary companies are payable in currencies other than U.S. dollars.
Management believes that these exposures are not material to our financial
position. Whenever deemed appropriate, we may hedge our exposure to foreign
currency movements.

The impact of the introduction of the Euro is discussed in the Liquidity and
Capital Resources section.


Interest Rate Risk.

We are exposed to interest rate risk in our financing instruments. Our long-term
financing is provided by fixed rate senior notes and floating rate bank debt. We
use derivative financial instruments for the purpose of reducing our exposure to
fluctuations in interest rates. We do not utilize derivative financial
instruments for trading or other speculative purposes. The counterparties to
these instruments are major financial institutions with high credit quality. We
are exposed to credit loss in the event of nonperformance by these
counterparties.

ITEM 1. LEGAL PROCEEDINGS

         We are involved in litigation from time to time in the ordinary course
of business. In management's opinion, the litigation in which we are currently
involved, individually and in the aggregate, is not material to us.

ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS

         (a) Not applicable.

         (b) Not applicable.

         (c) Not applicable.

         (d) Proceeds to us from our initial public offering, which closed on
February 16, 2000, after deduction of underwriting discounts and commissions
of approximately $33.6 million and offering expenses of approximately $3.8
million, totaled approximately $633.8 million. Of the $633.8 million raised
by us, approximately $105 million has been used to fund our equity
contribution to FLAG Atlantic Holdings Limited, $25 million has been used to
repay long term indebtedness, $28 million has been used for working capital
purposes, $32 million has been invested in FLAG Network Services and the
balance of the offering proceeds to us remains available to use to fund
additional expansions of the FLAG Telecom network and to develop additional
wholesale and bundled product and service offerings and for general corporate
purposes. The occurrence of unforseen events or changed business conditions
could cause us to use the proceeds of our initial public offering in a manner
other than as described above.

ITEM 3.  DEFAULTS UPON SENIOR SECURITIES

         Not applicable.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         During the third quarter of 2000, no meetings of our shareholders were
held.

ITEM 5.  OTHER INFORMATION

         (a) During the first quarter of 2000, we announced plans to begin
construction of FLAG Pacific-1, a system designed to link the cities of
Seattle, Vancouver, San Francisco, Los Angeles and Tokyo. We have entered
into a supply agreement for the subsea portion of the proposed cable project
and expect to use proceeds from our 11 5/8% Senior Notes offering, and other
debt financings and pre-sales to fund the construction of the project. We
cannot assure you, however, that we will successfully complete the project.

         (b) On July 10, 2000, we completed a registered offer to exchange up to
U.S.$300,000,000 aggregate principal amount of our privately placed 11 5/8%
Senior Notes due 2010 (which we refer to as the Initial Dollar Notes) and
300,000,000 Euro aggregate principal amount of our privately placed 11 5/8%
Senior Notes due 2010 (which we refer to as the Initial Euro Notes and, together
with the Initial Dollar Notes, our Initial Notes) for like principal amounts of
registered 11 5/8% Senior Notes due 2010. As of the expiration of the offer to
exchange on June 26, 2000 an aggregate of U.S.$300,000,000 principal amount of
the Initial Dollar Notes had been tendered for exchange in the offer and an
aggregate of 291,950,000 Euro principal amount of the Initial Euro Notes had
been tendered for exchange in the offer. We executed, and the Bank of New York,
as Trustee, authenticated, U.S.$300,000,000 aggregate principal amount of our
11 5/8% Senior Notes due 2010 (which we refer to as the Dollar Exchange Notes)
and 291,950,000 Euro aggregate



                                       23
<PAGE>

principal amount of our 11 5/8% Senior Notes due 2010 (which we refer to as our
Euro Exchange Notes and, together with the Dollar Exchange Notes, our Exchange
Notes) for issuance pursuant to the exchange. The Exchange Notes issued in the
offer to exchange have substantially the same terms and conditions as the
Initial Notes, except that the Exchange Notes are not subject to the
restrictions on resale or transfer which applied to the Initial Notes and which
continue to apply to the outstanding Initial Notes that were not tendered in the
offer to exchange. The Exchange Notes are listed on the Luxembourg Stock
Exchange.

         (c) As of September 25, 2000 Soopakij Chearavanont became a member
of our Board of Directors. Mr. Chearavanont is the shareholder representative
of K.I.N. (Thailand) Co. Ltd.
