                       NTL (TRIANGLE) LLC AND SUBSIDIARIES
                    UNAUDITED PRO FORMA FINANCIAL STATEMENTS


On November 23, 1999,  NTL  (Triangle)  LLC (formerly  NTL  (Bermuda)  LLC) (the
"Company")  sold its 50% interest in Cable  London PLC ("Cable  London") for (UK
Pound)  428,018,000  in cash to  Telewest  Communications  plc.  The  price  was
established  pursuant  to the  provisions  of an  agreement  between the parties
related to the Company's purchase in 1998 of Comcast UK Cable Partners Limited.

The sale of the Cable  London  interest is an "Asset  Sale" under the  Company's
11.20% Senior Discount Debentures due 2007 (the "2007 Discount Debentures"). The
Company will need to use an amount equal to the proceeds  from the sale to repay
subsidiary  debt or invest in  "Replacement  Assets"  within  365 days after the
sale,  otherwise  the  Company is  required  to make an offer to redeem the 2007
Discount Debentures at 100% of their accreted value up to an amount equal to the
proceeds.

The  unaudited  pro  forma  financial  statements  presented  are  based  on the
historical  financial  statements  of the Company and give effect to the sale of
Cable  London.  The  unaudited pro forma  condensed  consolidated  statements of
operations  for the year ended  December  31, 1998 and for the nine months ended
September  30,  1999 give  effect to the sale of Cable  London as if it had been
consummated on January 1, 1998. The unaudited pro forma  condensed  consolidated
balance  sheet as of September 30, 1999 gives effect to the sale of Cable London
as if it had been consummated on that date.

The Company made the following  pro forma  adjustment in the unaudited pro forma
condensed  consolidated balance sheet as of September 30, 1999: cash received of
(UK  Pound)  428,018,000  net of  investment  in  Cable  London  of  (UK  Pound)
24,171,000  resulting in a gain of (UK Pound) 403,847,000.  The Company made the
following pro forma adjustment in the unaudited pro forma condensed consolidated
statements of operations for the nine months ended September 30, 1999:  reversal
of the Company's equity in net loss of Cable London of (UK Pound) 5,573,000. The
Company made the  following  pro forma  adjustments  in the  unaudited pro forma
condensed consolidated  statements of operations for the year ended December 31,
1998:  (a) reversal of the consulting fee income from Cable London of (UK Pound)
407,000, (b) reversal of the Company's equity in net loss of Cable London of (UK
Pound)  11,855,000,  (c) gain on sale of Cable London of (UK Pound)  391,228,000
based  on the  January  1,  1998  investment  in  Cable  London  of  (UK  Pound)
36,790,000,  (d) reversal of the  consulting  fee income from  Birmingham  Cable
Corporation Limited  ("Birmingham") of (UK Pound) 531,000 due to the sale of the
Company's  27.5%  interest in Birmingham in October 1998 and (e) reversal of the
equity in net loss of Birmingham of (UK Pound) 7,841,000. Since the Company is a
pass-through  entity for U.S.  income tax  purposes  and is not  subject to U.S.
income  tax,  there  is no  income  tax  provision  included  in the  pro  forma
adjustments.

The pro forma  adjustments are based upon available  information and assumptions
that the Company  believes were  reasonable at the time made.  The unaudited pro
forma condensed  consolidated financial statements do not purport to present the
Company's  financial  position  or results of  operations  had the sale of Cable
London occurred on the dates indicated,  nor are they necessarily  indicative of
the  financial  position  or results of  operations  that may be achieved in the
future. The accompanying  unaudited  condensed  consolidated pro forma financial
statements should be read in connection with the historical financial statements
of the Company.
