                             RULE 12B-25(B) AND (C)

     If the subject  report could not be filed  without  unreasonable  effort or
expense  and  the  registrant  seeks  relief  pursuant  to Rule  12b-25(b),  the
following should be completed. (Check box if appropriate.)

          (a)  The reasons  described in  reasonable  detail in Part III of this
               form  could  not be  eliminated  without  unreasonable  effort or
               expense;

     [X]       (b) The subject annual  report,  semi-annual  report,  transition
               report on Form 10-K, 20-F, 11-K or Form N-SAR, or portion thereof
               will be filed on or before the 15th  calendar day  following  the
               prescribed  due  date;  or  the  subject   quarterly   report  or
               transition  report on Form 10-Q or portion  thereof will be filed
               on or before the fifth  calendar day following the prescribed due
               date; and

          (c)  The  accountant's  statement  or other  exhibit  required by Rule
               12b-25(c) has been attached if applicable.

                                    PART III

                                    NARRATIVE

     State below in  reasonable  detail the reasons why Form 10-K,  11-K,  20-F,
10-Q,  N-SAR or the transition  report portion thereof could not be filed within
the prescribed time period:

     We require  additional  time to prepare and file our Annual  Report on Form
10-K for the  fiscal  year  ended  December  31,  2000 in order to  prepare  the
financial  statements and explanatory notes to be included in the subject report
and to provide  the  related  disclosure  in the Form 10-K.  This  extension  is
required  primarily  due to  the  complexity  in the  application  of  SFAS  121
Accounting for the Impairment of Long-Lived Assets to be disposed of as a result
of recent events and  circumstances.  We have taken  reasonable steps to resolve
this matter,  but we have not yet been successful in doing so. We were therefore
unable to timely file our Form 10-K for the yearly  period  ended  December  31,
2000.

     We intend to file our Annual  Report on Form 10-K for the fiscal year ended
December  31,  2000 no later  than the  fifteenth  calendar  day  following  the
prescribed due date, as contemplated by Rule 12b-25(b)(2)  promulgated under the
Securities Exchange Act of 1934, as amended.

                                     PART IV

                                OTHER INFORMATION

     (1) Name and telephone number of person to contact in regard to this
notification:

            -------------------------------------------------------------
                    (Name)            (Area Code and Telephone Number)

     (2) Have all other periodic reports required under Section 13 or 15(d) of
the Securities  Exchange Act of 1934 or Section 30 of the Investment Company Act
of 1940  during the  preceding  12 months or for such  shorter  period  that the
registrant was required to file such report(s) been filed?  If the answer is no,
identify report(s).

               [X]  Yes  [ ]  No

     (3) Is it anticipated that any significant  change in results of operations
from the corresponding  period for the last fiscal year will be reflected by the
earnings statements to be included in the subject report or portion thereof?

               [X]  Yes  [ ]  No

     If so, attach an explanation of the anticipated  change,  both  narratively
and  quantitatively,  and, if  appropriate,  state the reasons why a  reasonable
estimate of the results cannot be made.

                           Name:   Shawn F. O'Donnell
                           Title:  Executive Vice President,

PART IV - OTHER INFORMATION

     We incurred  significant  losses in the twelve month period ending December
31, 2000. Because a significant  portion of these losses are the result of asset
impairments,  and  because we have not yet been able to  determine  the  precise
amount of their  impairment  adjustments,  we have not been able to finalize our
financial statements.  We estimate that our impairment adjustment will be in the
range of $250 to $270 million.  However,  because the market for these assets is
not well  developed,  our  valuations  are only  our  best  estimates  and it is
possible  that these assets could be worth more or less than their  written down
values in a future  asset  sale or sale as part of a viable  going  concern.  We
estimate  that our revenue for the twelve month period ended  December 31, 2000,
to be in the range of $40 to $45 million, as compared to revenue of $3.3 million
for 1999.  This  increase is mainly  attributable  to revenues  from our sale of
construction  services. We estimate that the cost of services for the year ended
December 31, 2000, to be  approximately  $15 million as compared to $8.2 million
for 1999.  This increase is related to operating  expenses as we put more of our
network into service. We expect our selling, general and administrative expenses
to be in the range of $35 to $40 million for the year ended  December  31, 2000,
compared to $14.7 in 1999.  The increase is  attributable  to  additional  staff
costs  incurred  as we  continued  to  develop  our  infrastructure,  along with
administrative  costs  related  to  obtaining  regulatory  status  and  deferred
compensation expense for stock options.

     Our current  cash  resources  and expected  revenues  from  operations  are
insufficient  to meet our  existing  obligations  and our  long-term  needs  for
continuing  operations.  We have been  unable to  obtain  sufficient  additional
financing to sustain our operations.  Consequently,  on April 2, 2001, we, along
with  several of our  subsidiaries,  filed  voluntary  petitions  for Chapter 11
bankruptcy  protection  with  the  U.S.  Bankruptcy  Court  of the  District  of
Delaware.  We have  petitioned  the court to allow us to operate our business as
debtors-in-possession.  There is substantial doubt as to our ability to continue
as a going concern. We are currently pursuing strategic alternatives that may be
available to us,  including a potential sale of all or a substantial  portion of
our business or assets, and a liquidation of the remainder.
