had cash flows of ($62) million for the three months ended March 31, 1998.

             LEVEL 3 COMMUNICATIONS, INC. AND SUBSIDIARIES

         Notes to Consolidated Condensed Financial Statements

1.     Basis of Presentation

The consolidated  condensed  balance sheet of Level 3  Communications,  Inc. and
subsidiaries  ("Level  3" or the  "Company"),  at  December  31,  1998  has been
condensed  from the Company's  audited  balance sheet as of that date. All other
financial  statements  contained  herein are  unaudited  and,  in the opinion of
management,  contain  all  adjustments  (consisting  only  of  normal  recurring
accruals)  necessary for a fair presentation of financial  position,  results of
operations and cash flows for the periods  presented.  The Company's  accounting
policies  and  certain  other  disclosures  are set  forth  in the  notes to the
consolidated  financial  statements  contained in the Company's Annual Report on
Form 10-K,  for the year ended  December 31, 1998.  These  financial  statements
should be read in conjunction with the Company's audited consolidated  financial
statements and notes thereto.  The  preparation  of the  consolidated  condensed
financial statements in conformity with generally accepted accounting principles
requires  management to make estimates and assumptions  that affect the reported
amount  of  assets  and  liabilities,   disclosure  of  contingent   assets  and
liabilities  and the reported amount of revenue and expenses during the reported
period. Actual results could differ from these estimates.

The Company has embarked on a plan to become a  facilities-based  provider (that
is, a provider that owns or leases a substantial portion of the property,  plant
and equipment  necessary to provide its services) of a broad range of integrated
communications  services in the United  States,  Europe and Asia.  To reach this
goal, the Company is expanding substantially the business of its PKS Information
Services,  Inc. subsidiary and creating,  through a combination of construction,
purchase  and  leasing  of  facilities  and  other  assets,   an  international,
end-to-end,  facilities-based  communications network (the "Business Plan"). The
Company is building the network based on Internet  Protocol  technology in order
to  leverage  the   efficiencies  of  this  technology  to  provide  lower  cost
communications services.

In 1997,  the Company  agreed to sell its energy  assets to  MidAmerican  Energy
Holding Company,  Inc. (f/k/a CalEnergy Company,  Inc.)  ("MidAmerican")  and to
separate the construction operations ("Construction Group") from the Company. On
January  2,  1998,  the  Company  completed  the sale of its  energy  assets  to
MidAmerican.  On March 31,  1998,  the Company  completed  the  split-off of the
Construction  Group to  stockholders  that held  Class C Stock.  Therefore,  the
results of operations of both  businesses  have been  classified as discontinued
operations on the consolidated condensed statements of operations for 1998.

On May 1, 1998, the Company's  Board of Directors  changed Level 3's fiscal year
end from the last  Saturday in December to a calendar  year end. The  additional
four days for the period  ending  September  30, 1998,  were not material to the
overall results of operations and cash flows.

The results of operations for the nine months ended  September 30, 1999, are not
necessarily indicative of the results expected for the full year.

Where appropriate,  items within the consolidated condensed financial statements
have been  reclassified  from the previous  periods to conform to current period
presentation.

2.     Reorganization - Discontinued Construction Operations

Prior to March 31,  1998,  the Company had a two-class  capital  structure.  The
Company's Class C Stock reflected the performance of the Construction  Group and
the Class D Stock reflected the performance of the other  businesses,  including
communications,  information  services  and coal  mining.  In 1997 the  Board of
Directors of Level 3 approved a proposal for the separation of the  Construction
Group  from the other  operations  of the  Company  through a  split-off  of the
Construction   Group  (the   "Split-off").   In  December  1997,  the  Company's
stockholders  approved the Split-off and in March 1998,  the Company  received a
ruling from the  Internal  Revenue  Service that stated the  Split-off  would be
tax-free to U.S. stockholders.  The Split-off was effected on March 31, 1998. As
a result of the  Split-off,  the  Company  no longer  owns any  interest  in the
Construction  Group.   Accordingly,   the  separate  financial   statements  and
management's  discussion  and  analysis of  financial  condition  and results of
operations of Peter Kiewit Sons',  Inc. should be obtained to review the results
of  operations  of the  Construction  Group for the three months ended March 31,
1998.

On March 31,  1998,  the Company  reflected  the fair value of the  Construction
Group as a distribution to the Class C stockholders because the distribution was
considered  non-pro rata as compared to the Company's previous two-class capital
stock  structure.   The  Company  recognized  a  gain  of  $608  million  within
discontinued  operations,  equal to the difference between the carrying value of
the  Construction  Group  and  its  fair  value  in  accordance  with  Financial
Accounting  Standards Board Emerging  Issues Task Force Issue 96-4,  "Accounting
for  Reorganizations  Involving a Non-Pro Rata Split-off of Certain  Nonmonetary
Assets to  Owners".  No taxes  were  provided  on this gain due to the  tax-free
nature of the Split-off.

In connection  with the Split-off,  the Class D Stock became the common stock of
Level 3 Communications,  Inc. ("Common Stock"),  and shortly  thereafter,  began
trading on the Nasdaq National Market under the symbol "LVLT".


3.     Discontinued Energy Operations

On January 2,  1998,  the  Company  completed  the sale of its energy  assets to
MidAmerican.   These  assets  included  approximately  20.2  million  shares  of
MidAmerican  common stock  (assuming  the exercise of 1 million  options held by
Level 3),  Level 3's 30% interest in CE Electric  and Level 3's  investments  in
international  power  projects  in  Indonesia  and  the  Philippines.   Level  3
recognized  an  after-tax  gain  on the  disposition  of  $324  million  and the
after-tax  proceeds of approximately $967 million from the transaction are being
used in part to fund the Business  Plan.  Results of  operations  for the period
through  January  2,  1998  were  not  considered  significant  and the  gain on
disposition was calculated  using the carrying amount of the energy assets as of
December 27, 1997.


4.     Earnings (Loss) Per Share

Basic earnings  (loss) per share have been computed  using the weighted  average
number of shares  during each  period.  The  Company had a loss from  continuing
operations  for the three and nine month  periods  ended  September 30, 1999 and
1998. Therefore,  the dilutive impact of the Convertible  Subordinated Notes and
the  21,534,433  options and  warrants  outstanding  at  September  30, 1999 and
19,690,144 options and warrants  outstanding at September 30, 1998 have not been
included in the  computation  of diluted  earnings  (loss) per share because the
resulting computation would have been anti-dilutive.

Effective August 10, 1998, the Company issued a dividend of one share of Level 3
Common  Stock  for each  share of Level 3 Common  Stock  outstanding.  All share
information and per share data have been restated to reflect the stock dividend.

The following  details the earnings  (loss) per share  calculations  for Level 3
Common Stock:

London-based Internet service provider in a largely stock-for-stock  transaction
valued at $12  million and  accounted  for as a purchase.  After  completion  of
certain adjustments, the Company agreed to issue approximately 400,000 shares of
Common  Stock and paid $1 million in cash in exchange  for all of the issued and
outstanding shares of BusinessNet's  capital stock. Of the approximately 400,000
shares Level 3 agreed to issue in connection with the acquisition, approximately
150,000  shares of Level 3 Common  Stock have been  pledged to Level 3 to secure
certain indemnification  obligations of the former BusinessNet stockholders.  In
October  1999,  Level 3 released  approximately  42,000  shares  pursuant to the
acquisition  agreement.  The  pledge  of the  remaining  shares  will  terminate
approximately 18 months from the acquisition  date,  unless  otherwise  extended
pursuant to the terms of the acquisition agreement.  Liabilities exceeded assets
acquired,  and goodwill of $16 million was recognized from the transaction which
is being amortized over five years.

On April 23, 1998, the Company  acquired XCOM  Technologies,  Inc.  ("XCOM"),  a
privately held company that has developed  technology which provides certain key
components  necessary  for the  Company  to  develop an  interface  between  its
Internet  Protocol-based  network and the  existing  public  switched  telephone
network.  The Company issued  approximately 5.3 million shares of Level 3 Common
Stock and 0.7  million options and warrants to purchase Level 3 Common  Stock in
exchange for all the stock, options and warrants of XCOM.

The  Company  accounted  for this  transaction,  valued  at $154  million,  as a
purchase.  Of the total purchase price, $115 million was originally allocated to
in-process  research and development and was taken as a nondeductible  charge to
earnings in the second  quarter of 1998.  The purchase  price  exceeded the fair
value  of the net  assets  acquired  by $30  million  which  was  recognized  as
goodwill.

In October 1998,  the  Securities  and Exchange  Commission  ("SEC")  issued new
guidelines  for valuing  acquired  research  and  development  which are applied
retroactively.  The Company believes its accounting for the acquisition was made
in accordance  with generally  accepted  accounting  principles and  established
appraisal  practices  at  the  time  of  the  acquisition.  However,  due to the
significance of the charge relative to the total value of the  acquisition,  the
Company  reviewed  the  facts  with the SEC.  Consequently,  using  the  revised
guidelines  and  assumptions,  the  Company  reduced  the charge for  in-process
research and  development  from $115 to $30 million,  and  increased the related
goodwill by $85 million.  The goodwill  associated with the XCOM  transaction is
being  amortized  over a five year  period.  The  results for the three and nine
months ended September 30, 1998 have been restated to reflect the reduced charge
for in-process research and development and increased amortization expense.

The  Company  believes  that its  resulting  charge for  acquired  research  and
development  conforms  to the  SEC's  expressed  guidelines  and  methodologies.
However,  no  assurances  can be given that the SEC will not require  additional
adjustments.

The  cumulative   operating   results  of  BusinessNet,   XCOM  and  other  1998
acquisitions  were  not  significant  relative  to the  Company's  1999 and 1998
results.

For the Company's  acquisitions,  the excess purchase price over the fair market
value of the  underlying  assets was allocated to goodwill and other  intangible
assets and property based upon  preliminary  estimates of fair value.  The final
purchase price allocation for XCOM did not vary  significantly  from preliminary
estimates. The Company does not believe that the final purchase price allocation
will vary significantly from the preliminary estimates for the entities acquired
after September 30, 1998.

Construction in Progress

The  Company  is  currently  constructing  its  communications   network.  Costs
associated  directly with the uncompleted  network and interest expense incurred
during  construction are capitalized  based on the weighted average  accumulated
construction   expenditures   and  the  interest  rates  related  to  borrowings
associated with the construction. Certain gateway facilities, local networks and
operating  equipment have been placed in service  during 1999.  These assets are
being depreciated over their useful lives, primarily ranging from 3-25 years. As
other  segments  of the  network  are  placed in  service,  the  assets  will be
depreciated over their useful lives.

The Company is currently  developing  business  support systems required for its
Business  Plan. The external  direct costs of software,  materials and services,
payroll and payroll related expenses for employees directly  associated with the
project and interest costs incurred when developing the business support systems
are  capitalized.  Upon  completion  of the  projects,  the  total  costs of the
business support systems are amortized over their useful lives of 3 years.

For the nine months  ended  September  30,  1999,  the Company  invested  $2,021
million  in its  communications  business,  including  $825  million on the U.S.
intercity  network,  $464  million on  international  networks,  $144 million on
transoceanic networks and $419 million on gateway facilities and local networks.

Capitalized  business support systems and network  construction  costs that have
not been  placed in service  have been  classified  as  construction-in-progress
within Property, Plant and Equipment below.

7.     Investments

The Company holds significant equity positions in two publicly traded companies;
RCN  Corporation   ("RCN")  and   Commonwealth   Telephone   Enterprises,   Inc.
("Commonwealth Telephone"). RCN is a facilities-based provider of communications
services to the residential  market primarily in the northeastern  United States
and California. RCN provides local and long distance phone, cable television and
Internet services in several markets;  including Boston,  New York,  Washington,
D.C., and California's San Francisco to San Diego corridor.

Commonwealth  Telephone holds Commonwealth Telephone Company, an incumbent local
exchange  carrier  operating in various rural  Pennsylvania  markets,  and CTSI,
Inc., a competitive local exchange carrier which commenced operations in 1997.

On  September  30,  1999,  Level  3  owned  approximately  35%  and  48%  of the
outstanding shares of RCN and Commonwealth Telephone, respectively, and accounts
for each  entity  using the equity  method.  The market  value of the  Company's
investment   in  the  two  entities  was  $1,092   million  and  $468   million,
respectively, on September 30, 1999.

The Company recognizes gains from the sale,  issuance and repurchase of stock by
its  subsidiaries  and equity method  investees in its statement of  operations.
During 1999, RCN issued stock in a public offering and for certain  transactions
which  diluted the  Company's  ownership of RCN from 41% at December 31, 1998 to
35% at September 30, 1999. The increase in the Company's  proportionate share of
RCN's net assets as a result of these transactions resulted in a pre-tax gain of
$5 million and $116  million for the Company for the three and nine months ended
September  30, 1999.  The Company  also  recognized a gain of $4 million and $25
million for the three and nine months ended  September 30, 1998 related to stock
transactions of RCN.

In October 1999, RCN announced that Vulcan  Ventures,  Inc. had agreed to invest
$1.65  billion in RCN.  This  transaction,  expected  to close  during the first
quarter of 2000, is in the form of preferred  stock  convertible to 26.6 million
shares of RCN common  stock.  The  preferred  shares must be converted to common
shares  within a three to seven year period at $62 per share.  Level 3, based on
current market  conditions,  expects to recognize a significant gain when Vulcan
Ventures, Inc. converts its RCN preferred stock to RCN common stock.

The  following  is  summarized  financial  information  of RCN and  Commonwealth
Telephone for the three and nine months ended  September 30, 1999 and 1998,  and
as of September 30, 1999 and December 31, 1998 (in millions):

9.     Long-Term Debt

6% Convertible Subordinated Notes

On September  14, 1999,  the Company  received  $798 million of proceeds,  after
transaction  costs, from an offering of $823 million aggregate  principal amount
of its 6% Convertible  Subordinated Notes Due 2009 ("Subordinated  Notes").  The
Subordinated  Notes are  unsecured and  subordinated  to all existing and future
senior indebtedness of the Company. Interest on the notes accrues at 6% per year
and is payable  each year in cash on March 15 and  September  15. The  principal
amount of the notes will be due on September 15, 2009.  The  Subordinated  Notes
may be converted into shares of common stock of the Company at any time prior to
maturity,  unless the Company has caused the  conversion  rights to expire.  The
conversion  rate  is  15.3401  shares  per  each  $1,000   principal  amount  of
Subordinated Notes, subject to adjustment in certain circumstances.  On or after
September 15, 2002, Level 3, at its option,  may cause the conversion  rights to
expire.  Level 3 may  exercise  this  option only if the  current  market  price
exceeds approximately $91.27 (which represents 140% of the conversion price) for
20 trading days within any period of 30  consecutive  trading days including the
last day of that period.

Debt issuance costs of $25 million were  capitalized  and are being amortized as
interest expense over the term of the Subordinated Notes.

Senior Secured Credit Facilities

On September 30, 1999, certain Level 3 subsidiaries  entered into $1.375 billion
of  secured  credit  facilities  ("Senior  Secured  Credit   Facilities").   The
facilities are comprised of a senior secured  revolving  credit  facility in the
amount of $650  million and a  two-tranche  senior  secured  term loan  facility
aggregating  $725  million.  The secured term loan  facility  consists of a $450
million tranche A and a $275 million tranche B term loan facilities.

On September 30, 1999, Level 3 borrowed $475 million under the secured term loan
facility.  The $475 million and prepaid interest have been placed in an interest
bearing escrow account until the Company receives the remaining state regulatory
approvals necessary to close this financing.  The Company expects to receive all
the necessary regulatory approvals during the fourth quarter of 1999.

The obligations under the revolving credit facility are secured by substantially
all the assets of Level 3 and, subject to certain  exceptions,  its wholly owned
domestic  subsidiaries (other than the borrower under the term loan facilities).
Such  assets   will  also  secure  a  portion  of  the  term  loan   facilities.
Additionally,  all obligations under the term loan facilities will be secured by
the equipment that is purchased with the proceeds of the term loan facilities.

Amounts  drawn under the secured  credit  facility  will bear  interest,  at the
option of the Company, at the alternate base rate or reserve-adjusted LIBOR plus
applicable margins. The applicable margins for the revolving credit facility and
tranche  A term  loan  facility  range  from 50 to 175  basis  points  over  the
alternate  base rate and from 150 to 275 basis  points  over LIBOR and are fixed
for the tranche B term loan  facility at 2.5% over the  alternate  base rate and
3.5% over LIBOR.  Interest and commitment fees on the revolving  credit facility
and  the  term  loan  facilities  are  payable  quarterly  with  specific  rates
determined by actual borrowings under each facility.

The revolving  credit  facility  provides for automatic and permanent  quarterly
reductions of the amount available for borrowing under that facility, commencing
at $17.25 million on March 31, 2004, and increasing to approximately $61 million
per quarter. The tranche A term loan facility amortizes in consecutive quarterly
payments  beginning on March 31, 2004,  commencing at $9 million per quarter and
increasing  to $58.5  million per quarter.  The  revolving  credit  facility and
tranche A term loan facility  mature on September  30, 2007.  The tranche B term
loan facility  amortizes with substantially all of the scheduled payments due in
equal amounts from March 31, 2007 to January 15, 2008.

The Senior Secured Credit  Facilities  contain  certain  covenants,  which among
other  things,  limit  additional  indebtedness,   dividend  payments,   certain
investments and  transactions  with  affiliates.  Level 3 and the borrowers must
also comply with specific  financial and operational  tests and maintain certain
financial ratios.

Debt  Issuance  costs of $23 million were  capitalized  and will be amortized as
interest expense over the terms of Senior Secured Credit Facilities.

Level 3 currently  intends to use the proceeds  from the Senior  Secured  Credit
Facilities and Subordinated Notes for working capital,  capital expenditures and
other general  corporate  purposes in connection with the  implementation of its
business plan, including the acquisition of telecommunications assets.

9.125% Senior Notes

On April 28, 1998,  the Company  received  $1.94 billion of net proceeds from an
offering of $2 billion  aggregate  principal amount 9.125% Senior Notes Due 2008
("Senior  Notes").  Interest  on the notes  accrues  at  9.125%  per year and is
payable on May 1 and November 1 each year in cash.

Debt issuance costs of $65 million were  capitalized  and are being amortized as
interest expense over the term of the Senior Notes.

10.5% Senior Discount Notes

On December 2, 1998, the Company sold $834 million aggregate principal amount at
maturity of 10.5% Senior Discount Notes Due 2008 ("Senior Discount Notes").  The
sales proceeds of $500 million,  excluding debt issuance costs, were recorded as
long term debt.  Interest on Senior  Discount  Notes accretes at a rate of 10.5%
per annum,  compounded  semiannually,  to an aggregate  principal amount of $834
million  by  December  1,  2003.  Cash  interest  will not  accrue on the Senior
Discount  Notes  prior to December  1, 2003;  however,  the Company may elect to
commence the accrual of cash interest on all  outstanding  Senior Discount Notes
on or after December 1, 2001. Accrued interest expense for the nine months ended
September  30,  1999 on the Senior  Discount  Notes of $40  million was added to
long-term debt.

Debt issuance costs of $14 million have been capitalized and are being amortized
as interest expense over the term of the Senior Discount Notes.

The Company  capitalized  $35 and $65 million of interest  expense and amortized
debt  issuance  costs  related  to network  construction  and  business  systems
development  projects for the three and nine months ended September 30, 1999 and
$5 million  and $6 million  for the three and nine months  ended  September  30,
1998.

10.    Employee Benefit Plans

The Company adopted the recognition  provisions of SFAS No. 123, "Accounting for
Stock Based Compensation" ("SFAS No. 123") in 1998. Under SFAS No. 123, the fair
value of an option (as computed in  accordance  with accepted  option  valuation
models)  on the date of grant is  amortized  over  the  vesting  periods  of the
options.  The recognition  provisions of SFAS No. 123 are applied  prospectively
upon adoption. As a result, the recognition  provisions are applied to all stock
awards  granted in the year of adoption and are not applied to awards granted in
previous  years  unless  those  awards  are  modified  or  settled in cash after
adoption of the recognition provisions. Although the recognition of the value of
the stock awards results in compensation or professional expenses in an entity's
financial   statements,   the  expense  differs  from  other   compensation  and
professional  expenses in that these  charges  will not be settled in cash,  but
rather, generally, through issuance of common stock.

The Company  believes  that the adoption of SFAS No. 123 will result in material
non-cash  charges  to  operations  in 1999 and  thereafter.  The  amount  of the
non-cash  charges  will be  dependent  upon a number of factors,  including  the
number of grants and the fair value of each grant  estimated  at the time of its
award.

Non-Qualified Stock Options and Warrants

The Company  granted 55,100  nonqualified  stock options with a fair value of $1
million  ("NQSO") to employees  during the nine months ended September 30, 1999.
The expense  recognized  for the three and nine months ended  September 30, 1999
for NQSOs and warrants outstanding at September 30, 1999 in accordance with SFAS
No. 123 was $1 million and $5 million,  respectively. In addition to the expense
recognized,  the  Company  capitalized  less than $1  million  and $1 million of
non-cash  compensation  costs for the three and nine months ended  September 30,
1999,  respectively,  related  to NQSOs  and  warrants  for  employees  directly
involved  in  the  construction  of  the  Internet   Protocol  network  and  the
development  of the business  support  systems.  As of September  30, 1999,  the
Company  had not  recognized  $7  million  of  compensation  costs for NQSOs and
warrants  granted in 1998 and 1999.  The  Company  recognized  $3 million and $9
million of expense for the three and nine months  ended  September  30, 1998 for
NQSOs and warrants  granted during the nine months ended  September 30, 1998. In
addition  to the  expense  recognized,  the  Company  capitalized  $1 million of
non-cash  compensation  costs for the three and nine months ended  September 30,
1998.

Outperform Stock Option Plan

In April 1998, the Company  adopted an outperform  stock option ("OSO")  program
that was  designed so that the  Company's  stockholders  would  receive a market
return on their  investment  before  OSO  holders  receive  any  return on their
options. The Company believes that the OSO program aligns directly  management's
and  stockholders'  interests  by basing  stock  option  value on the  Company's
ability to  outperform  the market in general,  as  measured  by the  Standard &
Poor's  ("S&P")  500 Index.  Participants  in the OSO program do not realize any
value from awards unless the Common Stock price  outperforms  the S&P 500 Index.
When the stock price gain is greater than the corresponding  gain on the S&P 500
Index,  the value  received  for awards under the OSO plan is based on a formula
involving  a  multiplier  related  to  the  level  by  which  the  Common  Stock
outperforms the S&P 500 Index.  To the extent that the Common Stock  outperforms
the S&P 500, the value of OSOs to a holder may exceed the value of non-qualified
stock options.

OSO grants are made quarterly to participants employed on the date of the grant.
Each  award  vests in equal  quarterly  installments  over two  years  and has a
four-year  life.  Each award  typically has a two-year  moratorium on exercising
from the date of grant.  As a result,  once a participant  is 100% vested in the
grant, the two year moratorium  expires.  Therefore,  each grant has an exercise
window of two years.

The fair value  recognized  under SFAS No. 123 for the 2,309,247 OSOs granted to
employees for services  performed  for the nine months ended  September 30, 1999
was $139  million.  The  Company  recognized  $35  million  and $74  million  of
compensation  expense for the three and nine months ended September 30, 1999 for
OSOs granted in 1999 and 1998. In addition to the expense recognized, $2 million
and $5 million of non-cash  compensation  was capitalized for the three and nine
months  ended  September  30,  1999  for  employees  directly  involved  in  the
construction  of the  Internet  Protocol  network  and  development  of business
support  systems.  As of September 30, 1999,  the Company had not recognized $99
million of  compensation  costs for OSOs  granted in 1998 and 1999.  The Company
recognized  $9 million  and $14 million of expense for the three and nine months
ended September 30, 1998 for OSOs outstanding at September 30, 1998. In addition
to the  expense  recognized  the  Company  capitalized  $1 million  of  non-cash
compensation for the three and nine months ended September 30, 1998.

Shareworks and Restricted Stock

The Company recorded $3 million and $7 million of non-cash  compensation expense
for the three and nine months ended September 30, 1999 related to the Shareworks
and  restricted  stock  programs  adopted in the third  quarter  of 1998.  As of
September 30, 1999,  the Company had not  recognized $9 million of  compensation
costs for Shareworks and restricted stock granted in 1998 and 1999. The non-cash
compensation  expense for the Shareworks and restricted  stock programs was less
than $1 million for the three and nine months ended September 30, 1998.

11.    Stockholders' Equity

On March 9, 1999 the Company  closed the offering of 28.75 million shares of its
Common Stock through an underwritten public offering.  The net proceeds from the
offering of approximately $1.5 billion after underwriting discounts and offering
expenses will be used for working capital,  capital  expenditures,  acquisitions
and other general  corporate  purposes in connection with the  implementation of
the Company's Business Plan.

12.    Industry Data

In 1998,  the Company  adopted SFAS No. 131  "Disclosures  about  Segments of an
Enterprise  and Related  Information".  SFAS No. 131  establishes  standards for
reporting  information about operating  segments in annual financial  statements
and requires selected  information about operating segments in interim financial
reports  issued  to  stockholders.  Operating  segments  are  components  of  an
enterprise  for which separate  financial  information is available and which is
evaluated regularly by the Company's chief operating decision maker, or decision
making  group,  in deciding how to allocate  resources  and assess  performance.
Operating segments are managed separately and represent strategic business units
that offer different products and serve different markets.

The  Company's  reportable  segments  include:  communications  and  information
services (including communications, computer outsourcing and systems integration
segments),   and  coal  mining.  Other  primarily  includes  California  Private
Transportation  Company L.P.  ("CPTC"),  a privately  owned tollroad in southern
California,  equity  investments  and other  corporate  assets and  overhead not
attributable to a specific segment.

Industry data for the Company's discontinued  construction and energy operations
are not included.

EBITDA, as defined by the Company,  consists of earnings (loss) before interest,
income taxes, depreciation, amortization, non-cash operating expenses (including
stock-based  compensation and in-process  research and development  charges) and
other non-operating income or expense. The Company excludes noncash compensation
due to its  adoption  of the  expense  recognition  provisions  of SFAS No. 123.
EBITDA is commonly used in the  communications  industry to analyze companies on
the basis of operating  performance.  EBITDA is not  intended to represent  cash
flow for the periods.

The information  presented in the table below includes information for the three
and nine  month  periods  ended  September  30,  1999  and  1998 for all  income
statement and cash flow  information  presented and as of September 30, 1999 and
December 31, 1998 for all balance sheet information presented.

13.    Related Party Transactions

Peter Kiewit Sons', Inc.  ("Kiewit") acted as the general  contractor on several
significant  projects for the Company in 1999 and 1998.  These projects  include
the  intercity  network,  local  loops and  gateway  sites,  the  Company's  new
corporate  headquarters  in Colorado  and a new data  center in Tempe,  Arizona.
Kiewit  provided  approximately  $592  million and $37  million of  construction
services  related to these  projects  in the first nine months of 1999 and 1998,
respectively.

Level 3 also receives certain mine management  services from Kiewit. The expense
for these  services was $9 million and $23 million for the three and nine months
ended September 30, 1999,  respectively  and $10 million and $27 million for the
three and nine months ended September 30, 1998, respectively, and is recorded in
selling, general and administrative expenses.


14.    Other Matters

Prior to the Split-off,  as of January 1 of each year,  holders of Class C Stock
had the right to convert  Class C Stock  into Class D Stock,  subject to certain
conditions.  In January  1998,  holders of Class C Stock  converted  2.3 million
shares, with a redemption value of $122 million, into 21 million shares of Class
D Stock (now known as Common Stock).

In August 1999 the Company was named as a defendant  in  Schweizer  vs.  Level 3
Communications,  Inc. et. al., a purported  national class action,  filed in the
District  Court,  County  of  Boulder,  State of  Colorado  which  involves  the
Company's  right to install  its fiber  optic  cable  network in  easements  and
right-of-ways  crossing the plaintiffs'  land. In general,  the Company obtained
the rights to construct its network from railroads,  utilities,  and others, and
is installing its network along the rights-of-way so granted.  Plaintiffs in the
purported  class action  assert that they are the owners of lands over which the
Company's fiber optic cable network passes,  and that the railroads,  utilities,
and others who granted the Company the right to construct and maintain its
network did not have the legal ability to do so. The action purports to be on
behalf of a national class of owners of land over which the  Company's network
passes or will pass.  The  complaint  seeks  damages on theories of trespass,
unjust enrichment and slander of title and property, as well as punitive
damages.  Although the Company is not aware of any  additional similar  claims,
the issues in the Schweizer  litigation  that may be based on similar or
different legal theories. Although it is too early for the Company to reach a
conclusion  as to the ultimate  outcome of this  litigation,  management
believes that the Company has substantial defenses to the claims asserted in the
Schweizer action (and any similar claims which may be named in the future), and
intends to defend them vigorously.

The  Company  is  involved  in various  other  lawsuits,  claims and  regulatory
proceedings  incidental to its business.  Management believes that any resulting
liability  for legal  proceedings  beyond that  provided  should not  materially
affect the Company's financial position,  future results of operations or future
cash flows.

Level 3 filed with the  Securities and Exchange  Commission a "universal"  shelf
registration  statement  covering up to $3.5 billion of common stock,  preferred
stock, debt securities and depositary shares that became effective  February 17,
1999. On March 9, 1999 the Company received  approximately $1.5 billion from the
sale of 28.75  million  shares of Common  Stock and on  September  14,  1999 the
Company  sold $823  million  aggregate  principal  amount of its 6%  Convertible
Subordinated Notes under the "universal" shelf registration statement.

Recent Developments

BusinessNet Ltd. Acquisition

On January 5, 1999, Level 3 acquired  BusinessNet  Ltd., a leading  London-based
Internet service provider in a largely stock-for-stock transaction valued at $12
million  and  accounted  for  as  a  purchase.   After   completion  of  certain
adjustments,  the Company agreed to issue approximately 400,000 shares of Common
Stock  and  paid $1  million  in  cash in  exchange  for all of the  issued  and
outstanding shares of BusinessNet's  capital stock. Of the approximately 400,000
shares Level 3 agreed to issue in connection with the acquisition, approximately
150,000  shares  of its  common  stock  have been  pledged  to Level 3 to secure
certain indemnification  obligations of the former BusinessNet stockholders.  In
October  1999,  Level 3 released  approximately  42,000  shares  pursuant to the
acquisition  agreement.  The  pledge  of the  remaining  shares  will  terminate
approximately 18 months from the transaction date.  Liabilities  exceeded assets
acquired,  and goodwill of $16 million was recognized from the transaction which
is being amortized over five years.

Common Stock Offering

On March 9, 1999 the Company  closed the offering of 28.75 million shares of its
Common Stock through a public  offering under the February 17, 1999  "universal"
shelf   registration   statement.   The  net  proceeds   from  the  offering  of
approximately $1.5 billion,  after underwriting discounts and offering expenses,
will be used for working capital,  capital expenditures,  acquisitions and other
general corporate purposes in connection with the implementation of the Business
Plan.

Increase in Authorized Shares Outstanding

On February 25, 1999, the Board of Directors  approved an increase in the number
of authorized shares of Common Stock from 500 million to 1 billion. On April 12,
1999,  the Board of  Directors  approved  a further  increase  in the  number of
authorized  shares of Common Stock by 500 million to 1.5 billion.  The Company's
stockholders  approved  the  increase  in  authorized  shares at its 1999 Annual
Meeting held on May 27, 1999.

Transatlantic Cable

On April 23, 1999,  Level 3 announced that it had contracted with Tyco Submarine
Systems Ltd. to design and build a transatlantic  terabit cable system from Long
Island,  New York to North  Cornwall,  UK. The cable system is expected to be in
service by September  2000 and is expected to cost between $600 to $800 million.
The total cost will depend on how the cable is upgraded  over time.  Level 3 has
prefunded the purchase of  significant  amounts of undersea  capacity as part of
the Business Plan, but may require  additional  funding depending on the cable's
ultimate structure, pre-construction sales and ownership.

European Network

Level 3 announced on April 29, 1999 that it had finalized  contracts relating to
construction  of  Ring  1 of  its  European  network  in  France,  Belgium,  the
Netherlands,  Germany  and the United  Kingdom.  Ring 1, which is  approximately
2,000 miles, will connect Paris, Frankfurt,  Amsterdam, Brussels and London. The
network is expected to be ready for service by September 2000. Ring 1 is part of
the approximately  4,750 mile intercity  network that will ultimately  connect a
minimum of 13 local city  networks  in Europe.  This  European  network  will be
linked  to  the  Level  3  North  American  intercity  network  by the  Level  3
transatlantic terabit cable system currently under development, also expected to
be ready for service by September 2000.

On July 26,  1999,  the Company  announced  two  important  developments  of its
European  network build with agreements with Eurotunnel and Alcatel.  Eurotunnel
will  provide  Level 3 with  multiple  cross-Channel  cables  between the United
Kingdom and continental Europe.  Eurotunnel will install and supply Level 3 with
multiple  cross-Channel cables between the United Kingdom and France through the
high-security service tunnel. The first of these cables will be completed by the
first quarter of 2000. Subsequent cables will be installed to upgrade and expand
the network as and when required or when new fiber technology becomes available.
Alcatel will provide Level 3 with a  cross-Channel  undersea  cable link between
the United  Kingdom and Belgium.  Alcatel will design,  develop,  and install an
undersea  cable to link the Level 3  network  between  the  United  Kingdom  and
Belgium.  The cable system is already  under  development  and is expected to be
completed during the first quarter of 2000.

Colt Cost Sharing Agreement

On May 4,  1999,  Level 3 and Colt  Telecom  Group  plc  ("Colt")  announced  an
agreement  to  share  costs  for the  construction  of  European  networks.  The
agreement calls for Level 3 to share  construction costs of Colt's planned 1,600
mile intercity German network linking Berlin,  Cologne,  Dusseldorf,  Frankfurt,
Hamburg,  Munich and Stuttgart. In return, Colt will share construction costs of
Ring 1 of Level 3's planned European network.

Lucent Agreement

On June 23, 1999 Level 3 announced a minimum four year,  $250 million  strategic
agreement with Lucent  Technologies to purchase  Lucent  systems,  including new
software switches or "softswitches."  The minimum purchase commitment is subject
to certain  conditions  and has the  potential  to grow to $1 billion  over five
years.

Under this  non-exclusive  agreement,  Lucent  will  provide  Level 3 its Lucent
Technologies  Softswitch,  a software switch for Internet Protocol networks that
is intended to combine the reliability  and features that customers  expect from
the  public  switched   telephone  network  with  the  cost   effectiveness  and
flexibility of Internet Protocol technology. With the Lucent Softswitch, Level 3
expects  to  provide  a full  range of  Internet  Protocol-based  communications
services  similar in quality and ease of use to service on  traditional  circuit
voice networks. In addition,  the companies also agreed to collaborate on future
enhancements of  softswitches  and gateway  products to support  next-generation
broadband  services for business and  consumers  that will combine  high-quality
voice and video communications with Internet-style web data services.

6% Convertible Subordinated Notes

Level 3 filed a "universal"  shelf  registration  statement  covering up to $3.5
billion of common stock,  preferred stock, debt securities and depository shares
that became  effective  February  17, 1999.  On  September  14, 1999 the Company
closed  the  offering  of $823  million  aggregate  principal  amount  of its 6%
Convertible  Subordinated  Notes Due 2009. The net proceeds from the offering of
approximately $798, after underwriting discounts and offering expenses,  will be
used for working capital,  capital expenditures,  acquisitions and other general
corporate  purposes in connection with the  implementation of its business plan,
including the acquisition of telecommunications assets.

Senior Secured Credit Facilities

On September 30, 1999 the Company  entered into $1.375 billion of senior secured
credit  facilities.  The facilities are comprised of a senior secured  revolving
credit  facility in the amount of $650 million and a two-tranche  senior secured
term loan facility  aggregating $725 million.  At September 30, 1999 the Company
borrowed $475 million under the  two-tranche  secured term loan facility.  These
funds and the prepaid  interest are  restricted  until certain state  regulatory
approvals are obtained.


Results of Operations

In late  1997,  the  Company  announced  a plan to  increase  substantially  its
information  services  business and to expand the range of services it offers by
building an advanced,  international,  facilities based  communications  network
based on Internet  Protocol  technology.  Since the Business  Plan  represents a
significant  expansion of the Company's  communications and information services
business,  the Company does not believe that the Company's  financial  condition
and  results  of  operations  for  prior  periods  will  serve  as a  meaningful
indication of the Company's future financial condition or results of operations.
The  Company  expects  to  incur   substantial  net  operating  losses  for  the
foreseeable  future  and it may not be  able to  achieve  or  sustain  operating
profitability in the future.

</TABLE>

Communications  and  information  services  revenue for the three  months  ended
September  30, 1999  increased  86%  compared  to the same  period in 1998.  New
products which the Company began offering in late 1998 and early 1999, including
private line,  colocation  and managed modem  services,  provided $36 million of
revenue for the communications segment in 1999. In 1998,  communications revenue
of $8 million was  directly  attributable  to XCOM which was  acquired in April
1998. A  significant  portion of XCOM's  revenue is  attributable  to reciprocal
compensation agreements with Bell Atlantic. These agreements require the company
originating a call to compensate the company  terminating  the call. The Federal
Communication Commission ("FCC") has been considering whether local carriers are
obligated to pay compensation to each other for the transport and termination of
calls to Internet service providers when a local call is placed from an end user
of one carrier to an Internet  service  provider  served by the competing  local
exchange  carrier.  Earlier this year,  the FCC  determined  that it had no rule
addressing inter-carrier compensation for these calls. The FCC also released for
comment  alternative federal rules to govern compensation for these calls in the
future. If state commissions, the FCC or the courts determine that inter-carrier
compensation does not apply,  carriers,  including the Company, may be unable to
recover their costs or will be compensated at a significantly lower rate and may
be  required  to  refund  amounts   previously   received.   In  May  1999  the
Massachusetts  Department  of Public  Utilities  ruled that Bell Atlantic was no
longer required to pay the established reciprocal compensation rates for certain
services. As a result Level 3 elected,  effective at the beginning of the second
quarter of 1999, not to recognize this revenue source until these  uncertainties
were resolved.  Bell Atlantic also notified the Company that it would escrow all
amounts due the Company under the reciprocal  compensation  agreements until the
issue was resolved. The Company reached a tentative agreement with Bell Atlantic
in October  1999.  The  agreement  establishes  new  intercarrier  or reciprocal
compensation rates between the two carriers and assures that the Company will be
paid for the traffic it terminates from Bell Atlantic. As part of the agreement,
the Company and Bell Atlantic  have also settled past  disputes over  reciprocal
compensation  billing issues.  The  implementation of the new rate structure and
the reciprocal  compensation  billing  settlements  are contingent  upon certain
conditions  including  approval  by  relevant  regulatory  authorities.  Revenue
attributable  to the Bell Atlantic  settlement  agreement will not be recognized
until the uncertainties related to the regulatory approvals have been resolved.

Revenue  for  the  computer  outsourcing  and  systems  integration   businesses
increased  6% and 23% to $17 million and $16 million,  respectively.  The growth
for the computer  outsourcing  business is attributable  to additional  services
provided to existing customers while the increase in system integration  revenue
is due to application outsourcing work performed for new clients.

Coal mining  revenue  decreased $3 million,  or 5% in the third  quarter of 1999
compared  to the same period in 1998.  This  decrease  is  primarily  due to the
expiration  of a  long-term  coal  contract  in 1998.  The  expiration  of these
contracts  are  expected  to result in a 10%  decline in coal  revenues in 1999.
Partially  offsetting  this  decline  was an  increase  in  shipments  taken  by
Commonwealth  Edison  Company  ("Commonwealth").  Commonwealth  is  obligated to
purchase annually, minimum amounts of coal; however, it is Commonwealth's option
as to when the coal will be purchased.

If current market conditions continue, the Company will experience a significant
decline in coal revenue and earnings beginning in 2001 as delivery  requirements
under long-term  contracts  decline as additional  long-term  contracts begin to
expire.

Other revenue is primarily  attributable  to CPTC, a privately owned tollroad in
southern California.

Cost of Revenue increased 113% in 1999 to $100 million from $47 million in 1998.
This increase was primarily due to the continued expansion of the communications
and  information  services  businesses.  Cost of revenue for the  communications
business  is expected  to  increase  substantially  in the future as the Company
continues to increase the number of markets in which it offers  services and the
products  available  in each of  those  markets.  The  cost of  revenue  for the
information services business was consistent with the corresponding  increase in
revenue. The cost of revenue for the coal business,  as a percentage of revenue,
increased  approximately 2% due to the expiration of the higher margin long-term
contract in 1998.

Depreciation and Amortization  expense increased to $63 million in 1999 from $15
million  in 1998.  The  commencement  of  operations  in 26 U.S.  and 4 European
markets and the completion of the initial  installation  of 17 local networks in
the second half of 1998 and 1999 resulted in the higher depreciation  expense in
1999. In addition, the amortization of goodwill attributable to the acquisitions
of GeoNet,  BusinessNet and others  contributed to the higher  depreciation  and
amortization expense in 1999.

Selling,  General and Administrative expenses increased significantly in 1999 to
$178 million from $96 million in 1998  primarily  due to the cost of  activities
associated  with the expanding  communications  business.  The Company  incurred
incremental  compensation  and travel  costs for the  substantial  number of new
employees  that have been hired to implement the Business Plan. The total number
of employees of the Company  increased to  approximately  3,600 at September 30,
1999.  Professional  fees  and  other  development  costs  associated  with  the
Company's  plans to  expand  services  offered  in the  U.S.,  Europe  and Asia,
consulting fees to develop and implement the Company's business support systems,
and  advertising,  marketing  and  other  selling  costs for the  Company's  new
Internet  Protocol  products and services also  increased  selling,  general and
administrative  expenses.  In addition to the costs to expand the communications
and  information  services  businesses,  the  Company  recorded  $39  million of
non-cash  compensation  expense in the third  quarter of 1999 under SFAS No. 123
related to grants of stock  options and  warrants.  General  and  administrative
costs are expected to increase  significantly  in future  periods as the Company
continues to implement the Business Plan.

EBITDA,  as  defined  by the  Company,  consists  of  earnings  (losses)  before
interest, income taxes, depreciation,  amortization, non-cash operating expenses
(including  stock-based  compensation  and in-process  research and  development
charges) and other non-operating income or expenses. EBITDA was $(25) million in
1998 and $(105)  million in 1999.  The primary  reason for the decrease  between
periods is the significant increase in cost of revenue and selling,  general and
administrative  expenses,  described  above,  incurred  in  connection  with the
implementation  of the Company's  Business Plan.  EBITDA is commonly used in the
communications   industry  to  analyze  companies  on  the  basis  of  operating
performance.  EBITDA,  however,  should  not be  considered  an  alternative  to
operating  or net income as an  indicator of the  performance  of the  Company's
businesses,  or as an alternative  to cash flows from operating  activities as a
measure of  liquidity,  in each case  determined in  accordance  with  generally
accepted accounting principles.  See "Consolidated  Condensed Statements of Cash
Flows".

Interest  Income  decreased  4% in 1999 to $51 million from $53 million in 1998.
The Company's average cash, cash equivalents and marketable  securities  balance
increased  slightly from  approximately $3.7 billion during the third quarter of
1998 to  approximately  $3.9 billion during the third quarter of 1999.  However,
the  weighted   average   yield  for  the  Company's   portfolio   decreased  by
approximately  50 basis points in 1999 primarily due to the funds being invested
in shorter term treasury securities. Pending utilization of the cash equivalents
and marketable securities in implementing the Business Plan, the Company intends
to invest the funds primarily in government and governmental  agency securities.
This investment strategy will provide lower yields on the funds, but is expected
to reduce  the risk to  principal  in the short term prior to using the funds in
implementing the Business Plan.

Interest Expense, net decreased from $46 million in 1998 to $34 million in 1999.
This  decrease  is  a  direct  result  of   capitalized   interest  for  network
construction  and business  support  systems  increasing from $5 million for the
three  months  ended  September  30, 1998 to $35  million for the  corresponding
period in 1999.  Interest costs on the Company's  outstanding debt increased due
to the issuance in December 1998 of $834 million  aggregate  principal amount at
maturity  of 10.5%  Senior  Discount  Notes due 2008 and the $823  million of 6%
Subordinated  Convertible  Notes due 2009 issued in September of this year.  The
amortization  of debt issuance costs  associated  with the Senior Discount Notes
and  Convertible  Subordinated  Notes also increased  interest  expense in 1999.
Interest  costs will  continue  to  increase  due to the Senior  Secured  Credit
Facilities entered into by the Company on September 30, 1999.

Gain on Equity Investee Stock  Transactions was $5 million in 1999. In the third
quarters  of 1998 and 1999 RCN  issued  stock  for  certain  acquisitions  which
diluted the Company's  ownership of RCN but increased its proportionate share of
RCN's net assets. The increase in the Company's proportionate share of RCN's net
assets  resulted  in a pre-tax  gain of $5 million  for the Company in the third
quarter of 1999. In 1998, the Company  recognized a $4 million gain in the third
quarter related to RCN stock activity.

Other  Expense,  net  increased in 1999 to $35 million  from $31 million.  Other
expense  consists  primarily of the  Company's  share of losses  incurred by the
Company's equity method investees, principally RCN. RCN is incurring significant
costs in developing  its business plan  including  the  acquisitions  of several
Internet  service  providers.  The Company recorded $37 million of equity losses
attributable  to RCN in the third quarter of 1999, as compared to $22 million in
the third  quarter of 1998.  In 1998,  the Company  elected to  discontinue  its
funding of Gateway  Opportunity  Fund, LP,  ("Gateway"),  which provided venture
capital to developing businesses.  The Company recorded losses of $11 million in
the  third  quarter  of 1998 to  reflect  Level  3's  equity  in  losses  of the
underlying  businesses  of Gateway.  Also  included in other  expense are equity
earnings in  Commonwealth  Telephone  Enterprises,  Inc., and realized gains and
losses on the sale of other  assets  each not  individually  significant  to the
Company's results of operations.

Income  Tax  Benefit in 1998 and 1999  differs  from the  statutory  rate of 35%
primarily  due to losses  incurred by the Company's  international  subsidiaries
which cannot be included in the consolidated U.S. federal return,  nondeductible
goodwill amortization expense and state income taxes.

Communications and information  services revenue increased from $102 million for
the nine months  ended  September  30, 1998 to $168  million for the nine months
ended  September 30, 1999. In May 1999 the  Massachusetts  Department of Public
Utilities ruled that Bell Atlantic was no longer required to pay the established
reciprocal compensation rates for certain services. As a result, Level 3 elected
not to recognize additional revenue, beginning in the second quarter, from these
agreements until the uncertainties are resolved. The Company reached a tentative
agreement  with Bell Atlantic in October 1999.  The  agreement  establishes  new
intercarrier  or  reciprocal  compensation  rates  between the two  carriers and
assures  that the Company will be paid for the traffic it  terminates  from Bell
Atlantic.  As part of the  agreement,  the Company and Bell  Atlantic  have also
settled  past  disputes  over  reciprocal   compensation   billing  issues.  The
implementation  of the new rate  structure and reciprocal  compensation  billing
settlement are contingent upon certain conditions including approval by relevant
regulatory  authorities.  Revenue  attributable to the Bell Atlantic  settlement
agreement  will  not  be  recognized  until  the  uncertainties  related  to the
regulatory approvals have been resolved.

Systems  integration  revenue increased 14% to $48 million in 1999.  Revenue for
the computer  outsourcing business increased 11% to $51 million in 1999. Revenue
attributable to new customers and additional services for existing customers led
to the increase in computer outsourcing and systems integration revenue.

Mining  revenue in 1999  decreased to $158 million from $178 million in 1998 due
to timing of  shipments  taken by  Commonwealth.  The  purchase  agreement  with
Commonwealth  requires that minimum amounts of coal must be purchased;  however,
it does  not  stipulate  when the  coal  must be  purchased.  In  addition,  the
expiration  of a long-term  contract in late 1998 will result in an  approximate
10% decline in 1999 coal sales from 1998 levels.

Other revenue, was consistent with 1998, and is primarily attributable to CPTC.

Cost of  Revenue  increased  $105  million  or 76% to $243  million in 1999 as a
result of the expanding  communications  business. In 1999 network expenses were
$107 million as compared to $4 million in the prior year.  The increase in costs
is  primarily  attributable  to the  XCOM and  GeoNet  acquisitions,  the  costs
associated   with  the  Frontier  and  IXC   Communications   leases  and  costs
attributable  to the products the Company began  offering in late 1998 and 1999.
The cost of revenue,  as a percentage of revenue,  for the information  services
business  increased  slightly  for the nine  months  ended  September  30,  1999
compared to the same period in 1998.  The increase is primarily due to the costs
incurred  by the  systems  integration  segment  to  transition  from  Year 2000
services to systems and software  reengineering  for Internet  Protocol  related
applications.  The cost of revenue  for the coal  business  as a  percentage  of
revenue,  increased due to the expiration of the high margin long-term  contract
in 1998.

Depreciation Expense increased from $31 million in 1998 to $155 million in 1999.
The  significant  increase in the amount of assets placed in service  during the
last half of 1998 and first nine months of 1999 for the communications  business
resulted in the increase in  depreciation  expense.  The  acquisitions  of XCOM,
GeoNet  and  BusinessNet  in 1998 and 1999  resulted  in  goodwill  amortization
increasing to $26 million in 1999.

Selling,  General and Administrative  expenses  increased  significantly to $460
million  in  1999  from  $199  million  in  1998  primarily  due to the  cost of
activities associated with the expanding communications business.  Compensation,
travel  and  facilities  costs  increased  substantially  due to the  additional
employees  that have been hired to implement the Business Plan. The total number
of employees of the Company  increased to  approximately  3,600 at September 30,
1999.  Professional  fees,  including  legal  costs  associated  with  obtaining
licenses,  agreements  and  technical  facilities  and other  development  costs
associated with the Company's plans to expand services offered in U.S., European
and Asian  markets,  consulting  fees  incurred  to develop  and  implement  the
Company's business support systems, and advertising, marketing and other selling
costs contributed to higher selling,  general and  administrative  expenses.  In
addition, the Company recorded $86 million of non-cash compensation in the first
nine months of 1999 for expenses recognized under SFAS No. 123 related to grants
of stock  options  and  warrants,  up from $23  million in 1998.  As the Company
continues to implement the Business Plan, general and  administrative  costs are
expected to continue to increase significantly.

Write-off of In-Process  Research and Development of $30 million in 1998 was the
portion of the purchase  price  allocated to the  telephone  network-to-Internet
Protocol  network  bridge  technology  acquired  by  the  Company  in  the  XCOM
transaction  and was estimated  through  formal  valuation.  In accordance  with
generally  accepted  accounting  principles,  the $30  million  was  taken  as a
nondeductible charge against earnings in the second quarter of 1998.

EBITDA  decreased  from  $(18)  million in 1998 to $(275)  million in 1999.  The
primary reason for the decrease  between periods is the significant  increase in
cost of revenue and  selling,  general and  administrative  expenses,  described
above, incurred in connection with the implementation of the Business Plan.

Interest  Income  increased  substantially  from  $124  million  in 1998 to $158
million in 1999  primarily  as a function of the  Company's  increasing  average
cash, cash  equivalents  and marketable  securities  balances.  The average cash
balance increased from  approximately  $2.9 billion during the first nine months
of 1998 to approximately $4 billion during the first nine months of 1999. Yields
on the portfolio,  however,  have declined  slightly from 1998. The accelerating
Business  Plan has  required the Company to shorten the average term of treasury
securities  in  which  it  invests  in  1999.  Pending  utilization  of the cash
equivalents  and marketable  securities in  implementing  the Business Plan, the
Company  intends to invest the funds  primarily in government  and  governmental
agency  securities.  This  investment  strategy will provide lower yields on the
funds,  but is expected to reduce the risk to  principal in the short term prior
to using the funds in implementing the Business Plan.

Interest  Expense,  net increased $46 million to $132 million in 1999 due to the
completion of the offering of $2 billion  aggregate  principal  amount of 9.125%
Senior Notes Due 2008 in April 1998, $834 million aggregate  principal amount at
maturity of 10.5% Senior  Discount  Notes Due 2008 offered in the fourth quarter
of 1998 and the 6% Convertible  Subordinated Notes issued in September 1999. The
amortization  of  the  related  debt  issuance  costs  also  contributed  to the
increased  interest expense in 1999. The Company  capitalized $65 million and $6
million of interest expense on network construction and business support systems
in the first nine months of 1999 and 1998, respectively.

Gain on Equity Investee Stock Transactions  increased to $116 million during the
first nine months of 1999. RCN issued stock in a public offering and for certain
transactions  which diluted the Company's  ownership of RCN from 41% at December
31,  1998  to  35%  at  September  30,  1999.  The  increase  in  the  Company's
proportionate  share of RCN's  net  assets  as a  result  of these  transactions
resulted in a pre-tax gain of $116 million from  subsidiary  stock sales for the
Company in the first nine months of 1999. The Company  recognized $25 million of
gains for similar stock transactions of RCN in 1998.

Other  Expense,  net  decreased to $65 million in 1999 from $78 million in 1998.
Other  expense  consists  of the  Company's  share  of  losses  incurred  by the
Company's equity method investees,  primarily RCN. RCN is incurring  significant
costs in developing  its business plan  including  the  acquisitions  of several
Internet  service  providers.  The Company recorded $90 million of equity losses
attributable to RCN in the first nine months of 1999, as compared to $75 million
in the first nine months of 1998.  The Company  also sold 1.2 million  shares of
Burlington  Resources  common stock,  resulting in a pre-tax gain of $17 million
for the Company in 1999. In 1998, the Company elected to discontinue its funding
of Gateway  Opportunity Fund, L.P., which provided venture capital to developing
businesses.  The Company recorded losses of $18 million in 1998 to reflect Level
3's equity in losses of the underlying businesses of Gateway. Equity earnings of
Commonwealth Telephone  Enterprises,  Inc. and gains on the disposition of other
assets  were not  individually  significant  in the first nine months of 1999 or
1998.

Income  Tax  Benefit in 1998 and 1999  differs  from the  statutory  rate of 35%
primarily  due to losses  incurred by the Company's  international  subsidiaries
which cannot be included in the consolidated U.S. federal return,  nondeductible
goodwill  amortization expense and state income taxes. The income tax benefit in
1998 also differs from the statutory  rate due to the $30 million  nondeductible
write-off  of  the  research  and   development   costs  acquired  in  the  XCOM
acquisition.

Discontinued  Operations  includes the one-time gain of $608 million  recognized
upon the distribution of the  Construction  Group to former Class C stockholders
on March 31, 1998. Also included in discontinued  operations is the gain, net of
tax, of $324 million from the Company's sale of its energy assets to MidAmerican
on January 2, 1998.

Financial Condition - September 30, 1999

The  Company's  working  capital  increased  $624 million  during 1999 from $3.5
billion at December 31, 1998 to $4.1 billion at September 30, 1999. The increase
was primarily due to the $1.5 billion equity  offering  completed in March 1999,
the $823 million offering of Convertible Subordinated Notes and the $475 million
proceeds  from the $1.375  billion of Senior  Secured  Credit  Facilities,  both
completed in September  1999.  The proceeds from these  offerings were partially
offset by the capital  expenditures and operating expenses incurred to implement
the Business Plan.

Cash provided by continuing  operations  increased  from $128 million in 1998 to
$360  million in 1999  primarily  due to the  changes in  components  of working
capital and an increase in interest income. Interest income increased in 1999 as
a result of the proceeds received from the Senior Notes,  Senior Discount Notes,
Convertible  Subordinated Notes and the March 1999 equity offering. The increase
in cash  provided by interest  income was  partially  offset by the  semi-annual
payment  of  interest  on the  Senior  Notes.  Interest  payments  on the Senior
Discount  Notes are  deferred  until  2004.  An  increase  in the costs  paid to
implement the Business Plan also reduced cash provided by continuing operations.

Investing activities include the purchase and sale of approximately $4.3 billion
and $4.4  billion,  respectively,  of  marketable  securities.  The Company also
incurred  costs of $2.1  billion for  capital  expenditures,  primarily  for the
expanding communications business. In addition, the Company realized $11 million
of proceeds from the sale of property, plant and equipment.

Financing  sources in the first nine months of 1999  consisted  primarily of the
net proceeds of $475  million from the Senior  Secured  Credit  Facilities,  net
proceeds of $798 million from the offering of $823 million  aggregate  principal
amount of 6%  Convertible  Subordinated  Notes Due 2009,  net  proceeds  of $1.5
billion  from the  issuance  of 28.75  million  shares of  Common  Stock and the
exercise of the Company's  stock options for $18 million.  The proceeds from the
Senior  Secured Credit  Facilities  and prepaid  interest have been placed in an
escrow account until the necessary regulatory approvals have been received.  The
Company also repaid long-term debt of $5 million during the first nine months of
1999.

Liquidity and Capital Resources

Since late 1997, the Company has substantially  increased the emphasis it places
on and the resources  devoted to its  communications  and  information  services
business.  The Company has  commenced the  implementation  of a plan to become a
facilities-based provider (that is, a provider that owns or leases a substantial
portion of the property,  plant and equipment necessary to provide its services)
of a broad range of integrated  communications services. To reach this goal, the
Company  is  expanding  substantially  the  business  of  its  subsidiary,   PKS
Information  Services,  Inc. to create,  through a combination of  construction,
purchase and leasing of facilities and other assets, an advanced, international,
facilities based  communications  network.  The Company is designing its network
based on Internet  Protocol  technology in order to leverage the efficiencies of
this technology to provide lower cost communications services.

The  development  of  the  Business  Plan  will  require   significant   capital
expenditures,  a  substantial  portion  of which  will be  incurred  before  any
significant related revenues from the Business Plan are expected to be realized.
These expenditures,  together with the associated early operating expenses,  may
result in substantial negative operating cash flow and substantial net operating
losses for the Company for the foreseeable future. Although the Company believes
that its cost  estimates  and  build-out  schedule  are  reasonable,  the actual
construction  costs or the timing of the  expenditures  may deviate from current
estimates.  The Company  estimates that its capital  expenditures  in connection
with the  Business  Plan will  approximate  $3  billion in 1999.  The  Company's
current  liquidity and the agreement with INTERNEXT should be sufficient to fund
the currently committed portions of the Business Plan.

The Company currently estimates that the implementation of the Business Plan, as
currently contemplated, will require between $9 and $11 billion over the 10 year
period of the Business  Plan.  The  Company's  ability to implement the Business
Plan and meet its  projected  growth is  dependent  upon its  ability  to secure
substantial  additional financing in the future. The Company expects to meet its
additional  capital  needs with the proceeds  from credit  facilities  and other
borrowings, including the $1.375 billion secured credit facility entered into on
September  30, 1999,  and sales or issuance of additional  equity  securities or
additional  debt  securities.  The 9 1/8%  senior  notes and the 10 1/2%  senior
discount  notes were issued  under  indentures  which permit the Company and its
subsidiaries  to incur  substantial  amounts of debt.  After the 6%  Convertible
Subordinated  Notes  offering,  the Company has  approximately  $1.1  billion of
securities   available  for  future   issuances  under  the  "universal"   shelf
registration  statement  that  was  declared  effective  by the  Securities  and
Exchange Commission in February 1999.

In  addition,  the  Company  may  sell or  dispose  of  existing  businesses  or
investments to fund portions of the Business Plan. The Company may sell or lease
fiber  optic  capacity,  or  access  to its  conduits.  The  Company  may not be
successful in producing  sufficient cash flow, raising sufficient debt or equity
capital on terms that it will consider  acceptable,  or selling or leasing fiber
optic  capacity  or  access  to  its  conduits.   In  addition,   proceeds  from
dispositions  of the  Company's  assets may not reflect  the  assets'  intrinsic
value.  Further,  expenses may exceed the Company's  estimates and the financing
needed may be higher than estimated.  Failure to generate  sufficient  funds may
require  the  Company  to delay  or  abandon  some of its  future  expansion  or
expenditures,  which could have a material adverse effect on the  implementation
of the Business Plan.

The Company may not be able to obtain  such  financing  if and when it is needed
and, if available, such financing may not be on terms acceptable to the Company.
If the Company is unable to obtain  additional  financing when needed, it may be
required to scale back  significantly its Business Plan and, depending upon cash
flow from its existing businesses, reduce the scope of its plans and operations.

In connection  with  implementing  the Business Plan,  management  will continue
reviewing  the  existing  businesses  of the  Company  to  determine  how  those
businesses will complement the Company's focus on communications and information
services.  If it is decided that an existing business is not compatible with the
communications and information  services business and if a suitable buyer can be
found, the Company may dispose of that business.

Year 2000

General

The Company's  wholly owned  subsidiary,  Level 3  Communications,  LLC is a new
Company that is implementing new technologies to provide Internet  Protocol (IP)
technology-based  communications  services  to its  customers.  The  Company has
adopted a strategy to select  technology  vendors  and  suppliers  that  provide
products  that are  represented  by such  vendors and  suppliers to be Year 2000
compliant. In negotiating its vendor and supplier contracts, the Company secures
Year 2000  warranties  that address the Year 2000  compliance of the  applicable
product(s).  As  part of the  Company's  Year  2000  compliance  program,  these
products are being tested to confirm they are Year 2000 ready.

PKS Systems Integration LLC ("PKSSI"), a subsidiary of PKS Information Services,
Inc. ("PKSIS") provides a wide variety of information technology services to its
customers.  In fiscal year 1998,  approximately  57% of the revenue generated by
PKSSI related to projects involving Year 2000 assessment and renovation services
performed by PKSSI for its customers. These contracts generally require PKSSI to
identify date affected fields in certain  application  software of its customers
and, in many cases,  PKSSI undertakes  efforts to remediate those  date-affected
fields so that Year 2000 data may be  processed.  Thus,  Year 2000 issues affect
many of the services  PKSSI  provides to its  customers.  This exposes  PKSSI to
potential risks that may include problems with services provided by PKSSI to its
customers and the potential for claims arising under PKSSI's customer contracts.
PKSSI  attempts to  contractually  limit its exposure to liability for Year 2000
compliance issues. However, there can be no assurance as to the effectiveness of
these contractual limitations.

Outlined  below  is  additional  information  with  respect  to  the  Year  2000
compliance  programs that are being pursued by Level 3  Communications,  LLC and
PKSIS.

Level 3 Communications, LLC

Level 3 Communications,  LLC ("Level 3"), uses software and related technologies
throughout its  business  that may be  affected  by the date  change in the Year
2000.  The inability of systems to appropriately  recognize the Year 2000 could
result in a disruption  of Level  3's  operations.  Level 3 has one main line of
business: delivery of  communications  services  to  commercial  clients  over
fiber optic cable. The delivery of service will be over Level 3 owned cable
when the network construction is complete.  In the interim,  services will be
delivered over both owned and leased lines.

Level 3 faces two primary Year 2000 issues with respect to its business.  First,
Level 3 must assess the  readiness  of its systems  that are required to provide
its customer's  communications  services ("Service Delivery  Systems").  Second,
Level 3 must evaluate the Year 2000 readiness of its internal  business  support
systems  ("Internal  Business  Support  Systems").  Level 3 must also verify the
readiness of the providers of the leased lines currently in use.

Level  3  has   designated  a  full-time  Year  2000  director  in  addition  to
establishing  a  program  office  staffed  in  part  by  experienced  Year  2000
consultants.  Level 3 is progressing through a comprehensive program to evaluate
and  address  the  effect  of the Year  2000 on its  Internal  Business  Support
Systems,  and the  Service  Delivery  Systems.  The plans'  focus upon Year 2000
issues consists of the following phases:

Phase

(I)      Assessment - Awareness,  commitment,  and  evaluation  which includes a
         detailed  inventory  of  systems  and  services  that the Year 2000 may
         impact.

(II)     Detailed Plan -  Establishment  of priorities,  development of specific
         action  steps and  allocation  of  resources  to address  the issues as
         outlined in Phase I.

(III)    Implementation  - Completion  of the  necessary  changes as delineated
         in Phase II.

(IV)     Verification - Determining whether the conversions implemented in Phase
         III  have   resolved  the  Year  2000  problem  so  that  date  related
         calculations will function properly, both as individual units and on an
         integrated  basis.  This will culminate in an end-to-end system test to
         ensure  that the  customer  services  being  delivered  by Level 3 will
         function  properly and that all support services  necessary to business
         operations will be Year 2000 compliant.

(V)      Contingency  Plans - Establishment  of alternative  plans should any of
         the services or suppliers  that Level 3 requires to do business fail to
         be Year 2000 ready.

With respect to its Year 2000 plans,  Level 3 currently has activities  underway
primarily in phases IV and V. The current stage of activities  varies based upon
the type of component, system, and/or customer service at issue.

</TABLE>

  *   Level 3 anticipates  this range of activity to continue through 1999 as it
      adds  new  equipment  and  services  while  building  its  infrastructure.
      Additionally,  the upgrading of service  delivery  through its proprietary
      systems will require  that the  delivery  systems go through  verification
      with each new innovation.

The  expenses  associated  with this  project by Level 3, as well as the related
potential  effect on Level 3's  earnings,  are not  expected  to have a material
effect on the future operating results or financial  condition of Level 3. There
can be no assurance,  however, that the Year 2000 problem, and any loss incurred
by any customers of Level 3 as a result of the Year 2000 problem,  will not have
a  material  adverse  effect on Level 3's  financial  condition  and  results of
operations.

Level 3 has significant  relationships  and dependencies  with regard to systems
and  technology  provided  and  supported  by third  party  vendors  and service
providers.  In particular,  the customer delivery systems for the communications
business   of  Level  3  are   dependent   upon  third   parties   who   provide
telecommunication  services while the  infrastructure  continues to be built. As
part of its Year 2000  program,  Level 3 has sought to obtain  formal  Year 2000
compliance  representation  from  vendors who provide  products  and services to
Level 3. The vendor compliance process is being performed  concurrently with the
Company's  ongoing Year 2000  validation  activities.  This  compliance  process
consists of obtaining  information from  disclosures made publicly  available on
company  websites,   reviewing  test  plans  and  results  made  available  from
suppliers, and following up with letters and phone calls to any vendors who have
not made such information available to Level 3 as yet.

Because of the aforementioned  reliance placed on third party vendors, Level 3's
estimate of costs to be incurred could change  substantially  should one or more
of the vendors be unable to timely deliver Year 2000 compliant products. Level 3
does not own the proprietary  hardware technology or third party software source
code utilized in its business and therefore,  Level 3 cannot  actually  renovate
the  hardware or third party  software  identified  as having Year 2000  support
issues.  The standard  components  supplied by vendors for the customer delivery
systems  have been  tested in  laboratory  settings  and  certified  as to their
compliance.

With respect to the  contingency  plans for Level 3, such plans  generally  fall
into two categories.  Concerning the customer delivery systems of Level 3, Level
3 has certain redundant and backup facilities,  such as on-site generators. With
respect to systems  obtained  from third party  vendors,  contingency  plans are
developed by Level 3 on a case by case basis where deemed appropriate.

PKSIS

PKSIS and its subsidiaries use software and related technologies  throughout its
business that may be affected by the date change in the Year 2000. The inability
of systems to appropriately recognize the Year 2000 could result in a disruption
of PKSIS operations.  PKSIS has two main lines of business: computer outsourcing
and systems  integration.  The computer  outsourcing  business is managed by PKS
Computer Services LLC ("PKSCS"). The systems integration is managed by PKSSI.

PKSCS generally faces two primary Year 2000 issues with respect to its business.
First,  PKSCS must  evaluate the Year 2000  readiness  of its  internal  support
systems.  Second,  PKSCS must assess and, if  necessary,  upgrade the  operating
environments  which  PKSCS  provides  for  its  outsourcing   customers.   PKSCS
outsourcing   customers  are  responsible   for  their  own   application   code
remediation.

PKSCS established a corporate-wide  Year 2000 program in 1997, which in relation
to other  business  projects and  objectives  has been assigned a high priority,
including  the  designation  of  a  full-time  year  2000  director.   PKSCS  is
progressing  through a comprehensive  program to evaluate and address the effect
of the  Year  2000 on its  internal  operations  and  support  systems,  and the
operating systems which PKSCS is responsible for providing to its  outsourcing
customers.  Due to the nature of its business,  PKSCS has developed and is
administering  approximately twenty separate Year 2000 project plans.
Approximately  eighteen of these plans are devoted to the specific operating
systems software upgrades to be undertaken by  PKSCS for its outsourcing
customers according to software vendor specifications.  The  remaining  plans
focus upon Year 2000  issues  relating to PKSCS internal  support  systems.
PKSCS is utilizing both internal and external resources in implementing
these plans.  These PKSCS plans generally  consist of the following phases:

Phase

(I)      Assessment - Awareness,  commitment,  and evaluation,  which includes a
         detailed  inventory  of  systems  and  services  that the Year 2000 may
         impact.

(II)     Detailed Plan -  Establishment  of priorities,  development of specific
         action  steps and  allocation  of  resources  to address  the issues as
         outlined in Phase I.

(III)    Implementation  -  Completion  of  the  necessary  changes  per  vendor
         specifications,  (that is,  replacement  or  retirement) as outlined in
         Phase II.

(IV)     Verification  -  With  respect  to  PKSCS'  internal  support  systems,
         determining  whether  the  conversions  implemented  in Phase  III have
         resolved the Year 2000 problem so that date related  calculations  will
         function properly, both as individual units and on an integrated basis.

(V)      Completion - The final rollout of components into an operational unit.

(VI)     Tracking - Monitor vendor  specifications to assess ongoing replacement
         of components as dictated by the vendors.

With respect to its Year 2000 plans, PKSCS currently has activities  underway in
phases V and VI. The current stage of  activities  varies based upon the type of
component,  system,  and/or customer service at issue.  Some PKSCS customers had
delayed or  postponed  operating  system  upgrades to be performed by PKSCS as a
result of the customer's delay in its application code remediation  schedule. To
date,  PKSCS,  as directed  and  approved by its customer  base,  has  completed
required  IBM  System  390  operating  system  upgrades  to Year 2000  readiness
software  versions.   PKSCS  continues  to  monitor  vendor  Year  2000  version
acceptance  specifications  to  assess  ongoing  replacement  of  components  as
dictated by the vendors.

PKSSI generally faces two primary Year 2000 issues with respect to its business.
First, PKSSI provides a wide variety of information  technology  services to its
customers which could potentially expose PKSIS to contractual liability for Year
2000  related  risks if services are not  performed in a timely or  satisfactory
manner.  Second,  PKSSI must evaluate and, if necessary,  upgrade or replace its
internal  business  support  systems  which  may have date  dependencies.  PKSSI
believes  the  primary  internal  systems  affected by the Year 2000 issue which
could have an impact on its  business  are  desktop  and  network  hardware  and
software.  PKSSI  previously  completed its Year 2000  assessment of desktop and
network hardware and software, and, based on vendor representations,  determined
that some upgrades and replacements are required. PKSIS is in the process of
upgrading and replacing certain desktop and network  hardware and software
previously  identified  as non-Year  2000 ready, which such upgrade and
replacement  activities  are targeted for  completion in November 1999. PKSIS
continues to validate these findings and currently plans to do so  throughout
the  remainder  of  1999.  PKSSI  is also in the  process  of communicating with
its vendors to assess its servers and communications hardware for Year 2000
readiness.

In fiscal year 1998, approximately 57% of the revenue generated by PKSSI related
to projects involving Year 2000 assessment and renovation  services performed by
PKSSI for its  customers.  This is a reduction  from 80% in 1997.  Some of these
contracts require PKSSI to identify date affected fields in certain  application
software  of its  customers  and,  in many cases,  PKSSI  undertakes  efforts to
remediate  those  date-affected  fields so that Year 2000 data may be processed.
Thus, Year 2000 issues affect certain  services PKSSI provides to its customers.
This exposes  PKSSI to potential  risks that may include  problems with services
provided by PKSSI to its customers  and the  potential for claims  arising under
PKSSI's customer contracts. In some cases PKSSI has contractual warranties which
could require PKSSI to perform Year 2000 related  services  after the year 2000.
PKSSI  attempts to  contractually  limit its exposure to liability for Year 2000
compliance issues. However, there can be no assurance as to the effectiveness of
such contractual limitations.

The  following  chart  describes  the status of PKSIS'  Year 2000  program  with
respect to Computer Outsourcing Services and Systems Integration Services.

</TABLE>

PKSIS has significant  relationships and dependencies with regard to systems and
technology  provided and supported by third party vendors and service providers.
In  particular,  the computer  outsourcing  business of PKSCS is dependent  upon
third parties who provide  telecommunication  service,  electrical utilities and
mainframe and midrange hardware and software providers. As part of its Year 2000
program,  PKSIS has sought to obtain formal Year 2000 compliance  representation
from vendors who provide products and services to PKSIS.  The vendor  compliance
process is being  performed  concurrently  with the Company's  ongoing Year 2000
remediation activities.  PKSCS is also working with its outsourcing customers to
inform them of certain  dependencies  which  exist which may affect  PKSIS' Year
2000  efforts  and  certain  critical  actions  which  PKSIS  believes  must  be
undertaken  by the customer in order to allow PKSIS to  implement  its Year 2000
efforts  concerning  the  operating  software  system  provided by PKSCS for its
customers.

To date,  PKSCS has received  written  responses from  approximately  40% of the
vendors from whom it has sought Year 2000 compliance statements. With respect to
those key third  party  vendors  and  suppliers  who have  failed to  respond in
writing,  PKSIS is following up directly  with such  vendors and  suppliers  and
obtaining  information  from other sources,  such as  disclosures  made publicly
available  on  company  websites.  Additionally,  PKSCS has  contracted  with an
independent Year 2000 vendor  compliance  advisory service to assist with PKSCS'
verification of its understanding of each appropriate vendor's product year 2000
readiness and compliance version statements.

Because of this reliance on third party vendors,  PKSIS' estimate of costs to be
incurred could change  substantially should one or more of the vendors be unable
to  timely  deliver  Year  2000  compliant  products.  PKSCS  does  not  own the
proprietary  hardware technology or third party software source code utilized in
its  business and  therefore,  PKSCS  cannot  actually  renovate the hardware or
software identified as having Year 2000 support issues.

The expenses  associated  with PKSIS' Year 2000 efforts,  as well as the related
potential effect on PKSIS' earnings,  are not expected to have a material effect
on the future operating results or financial  condition of Level 3. There can be
no assurance,  however, that the Year 2000 problem, and any loss incurred by any
customers of PKS as a result of the Year 2000 problem,  will not have a material
adverse effect on Level 3's financial condition and results of operations.

With respect to the contingency  plans for PKSCS, such plans generally fall into
two  categories.  Concerning the internal  support  systems of PKSCS,  PKSCS has
certain  redundant  and backup  facilities,  such as on-site  generators,  water
supply and pumps.  PKSCS has undertaken  contingency plans with respect to these
internal  systems by performing  due diligence with the vendors of these systems
in order to investigate  the Year 2000 compliance  status of these systems,  and
such  systems  are tested on a monthly  basis.  With  respect  to the  operating
systems  obtained  from third  party  vendors  and  maintained  by PKSCS for its
outsourcing  customers,  contingency  plans  are  developed  by  PKSCS  and  its
customers  on a case by case  basis  as  requested,  contracted  and paid for by
PKSCS'  customers.  However,  there is no  contingency  plan for the  failure of
operating system software to properly handle Year 2000 date  processing.  If the
operating system software  provided to PKSIS by third party vendors fails at the
PKSCS Data Center,  such vendor supplied software is expected to fail everywhere
and no immediate  work around could be supplied by PKSCS.  In the event computer
hardware  supplied by PKSCS for its outsourcing  customer fails,  some customers
have contracted for contingency  plans through  disaster  recovery  arrangements
with a third party which supplies disaster recovery services.

Costs of Year 2000 Issues

Level 3  currently  expects  to incur  approximately  $12.5  million of costs in
aggregate,  through  the end of 1999.  These costs  primarily  arise from direct
costs of Level 3 employees  verifying equipment and software as Year 2000 ready.
However,  Level 3 does not separately track the internal employee costs incurred
for its Year 2000  projects.  Level 3 does track all material costs incurred for
its Year 2000  projects as well as all costs  incurred by the Year 2000  program
office.  Level 3 has estimated the time and effort  expended by its employees on
Year 2000 projects based on an analysis of Year 2000 project plans.

PKSIS  incurred  approximately  $4.2 million of costs to implement its Year 2000
program through 1998, and currently expects to incur an additional approximately
$6.0  million  of costs in  aggregate,  in 1999.  Of these costs, PKSIS expects
to incur $24 million to upgrade its internal network infrastructure, including
servers, desktops and phone systems.  The remaining costs primarily arise from
direct costs of PKSCS employees working on upgrades per vendor specifications
of operating system software for  PKSCS  outsourcing customers and the cost of
vendor supplied  operating  systems software  upgrades and the cost of
additional  hardware.  However,  PKSIS does not separately track the internal
costs  incurred for its Year 2000  projects and does not track the cost and time
its employees spend on Year 2000 projects. PKSCS has estimated the time and
effort  expended by its  employees  on Year 2000  projects  based on an analysis
of Year 2000 project  plans.  Labor costs for PKSCS' Year 2000 projects were
estimated to be $2.1 million for 1998 and are estimated to be approximately
one million  dollars for 1999,  when such projects are  currently  scheduled for
completion.  These labor costs will  necessarily  increase if such projects take
longer to complete. Costs for software upgrades,  additional equipment costs and
a test system for PKSCS' Year 2000  projects  were  estimated to be $2.1 million
for 1998 and are  estimated  to be $2.5  million  for 1999.  Such  costs are not
available  for PKSSI but are not  believed to be  material.  Year 2000 costs for
PKSSI are believed to be  substantially  less than PKSCS and focus  primarily on
the cost of evaluating and, if necessary, upgrading network and desktop hardware
and software.  The costs incurred by PKSSI for performing Year 2000 services for
its customers are included within PKSSI's pricing for such services.

Risks Associated with Year 2000 Issues

Due to the  complexity of the issues  presented by the Year 2000 date change and
the proposed  solutions,  and the  interdependence  of external  vendor  support
services,  it is  difficult  to assess  with any degree of  accuracy  the future
effect of a failure in any one aspect or combination of aspects of the Company's
Year 2000 activities.  The Company cannot provide  assurance that actual results
will not differ from  management's  estimates due to the complexity of upgrading
the systems and related technologies surrounding the Year 2000 issue.

Failure  by the  Company to  complete  its Year 2000  activities  in a timely or
complete  manner,  within its estimate of projected  costs,  or failure by third
parties,  such  as  financial   institutions  and  related  networks,   software
providers,  local telephone  companies,  long distance providers and electricity
providers  among  others,  to correct  their  systems,  with which the Company's
systems  interconnect,  could have a  material  effect on the  Company's  future
results of operations and financial position.  Other factors which might cause a
material difference from management's estimate would include, but not be limited
to, the availability and cost of personnel with appropriate skills and abilities
to locate and upgrade relevant  computer systems and similar  uncertainties,  as
well as the  related  effects  on the  Company  of the Year 2000  problem on the
economy in general,  or on the  Company's  business  partners  and  customers in
particular.

Market Risk

Level 3 is subject to market  risks  arising  from  changes in  interest  rates,
equity prices and foreign  exchange  rates.  The Company's  exposure to interest
rate risk increased due to the $1.375 billion Senior Secured Credit Facilities
entered into by the Company in September 1999. As of September 30, 1999, the
Company had borrowed $475 million under Senior Secured Credit  Facilities.
Amounts drawn on the term loan and revolving credit facilities bear interest at
the alternate base  rate or  reserve-adjusted  LIBOR  rate  plus  applicable
margins.  As the alternate base rate and  reserve-adjusted LIBOR rate fluctuate,
so to will the interest expense on amounts borrowed under the facilities. The
Company continues to evaluate alternatives to limit interest rate risk.

Level 3  continues  to hold  positions  in  certain  publicly  traded  entities,
primarily  Commonwealth  Telephone  and RCN. The Company  accounts for these two
investments  using the equity method.  The market value of these  investments is
approximately  $1.560 billion as of September 30, 1999,  which is  significantly
higher than their carrying value of $332 million. The Company does not currently
have plans to dispose of these  investments,  however,  if any such  transaction
occurred, the value received for the investments would be affected by the market
value  of the  underlying  stock  at the  time of any  such  transaction.  A 20%
decrease in the price of  Commonwealth  Telephone  and RCN stock would result in
approximately a $312 million  decrease in fair value of these  investments.  The
Company  does not  currently  utilize  financial  instruments  to  minimize  its
exposure to price fluctuations in equity securities.

The Company's  Business Plan includes  developing and  constructing  networks in
Europe and Asia. As of September 30, 1999, the Company has invested  significant
amounts of capital in Europe and will  continue to expand its presence in Europe
and Asia in 1999 and 2000.  To date,  the  Company  has not  utilized  financial
instruments  to minimize  its  exposure to foreign  currency  fluctuations.  The
Company will continue to analyze risk  management  strategies to reduce  foreign
currency exchange risk in the future.

The change in equity security  prices is based on hypothetical  movements and is
not necessarily indicative of the actual results that may occur. Future earnings
and losses will be affected by actual  fluctuations  in interest  rates,  equity
prices and foreign currency rates.

                            PART II - OTHER INFORMATION


Item 1.    Legal Proceedings

In August 1999 the Company was named as a defendant  in  Schweizer  vs.  Level 3
Communications,  Inc. et. al., a purported  national class action,  filed in the
District  Court,  County  of  Boulder,  State of  Colorado  which  involves  the
Company's  right to install  its fiber  optic  cable  network in  easements  and
right-of-ways  crossing the plaintiffs'  land. In general,  the Company obtained
the rights to construct its network from railroads,  utilities,  and others, and
is installing its network along the rights-of-way so granted.  Plaintiffs in the
purported  class action  assert that they are the owners of lands over which the
Company's fiber optic cable network passes,  and that the railroads,  utilities,
and others who  granted  the Company the right to  construct  and  maintain  its
network  did not have the legal  ability to do so. The action  purports to be on
behalf of a national  class of owners of land over which the  Company's  network
passes or will pass. The complaint seeks damages on theories of trespass, unjust
enrichment  and  slander of title and  property,  as well as  punitive  damages.
Although the Company is not aware of any additional  similar claims, the Company
may in the future receive  claims and demands  related to  rights-of-way  issues
similar to the issues in the Schweizer  litigation  that may be based on similar
or different legal theories. Although it is too early for the Company to reach a
conclusion as to the ultimate  outcome of this litigation,  management  believes
that  the  Company  has  substantial  defenses  to the  claims  asserted  in the
Schweizer action (and any similar claims which may be named in the future), and
intends to defend them vigorously.

                  For  purposes  of  the  foregoing,  (a)  each  change  in  the

be  effective,  in the case of an upgrade,  during the period  commencing on and
including  the  date  of  delivery  to  the  Administrative   Agent  of  written
notification  thereof from Level 3 and ending on the date immediately  preceding
the  effective  date of the next such change  and,  in the case of a  downgrade,
during the period  commencing on and  including the date of public  announcement
thereof and ending on the date  immediately  preceding the effective date of the
next such change,  (b) in the event the ratings  established  by Moody's and S&P

which case  interest  rate spreads will be based on a rating one Level above the
lower of the two ratings and (c) if neither  Moody's nor S&P  maintains a rating
for the Index Debt,  the ratings shall be deemed to be in Level I. If the rating
system of Moody's or S&P shall  change,  or if either of them shall cease rating
the Index  Debt  (other  than by reason of any  action or  nonaction  by Level 3
following  or  in  anticipation  of  a  ratings  downgrade),  Level  3  and  the
Administrative Agent shall negotiate in good faith to amend (with the consent of
the Required  Lenders) the  references  to specific  ratings in this  definition
(including by way of substituting  another rating agency mutually  acceptable to
Level 3 and the Administrative Agent for the rating agency with respect to which
the  rating  system  has  changed  or for which no rating is then in  effect) to
reflect such changed rating system or the  nonavailability  of ratings from such
rating agency,  and pending  agreement on such  amendment,  the rating in effect
immediately  prior to such change or cessation will apply.  If any rating agency
shall not have a rating in effect by reason of any action or  nonaction by Level
3 following or in anticipation of a ratings  downgrade,  then such rating agency
shall be deemed to have established a rating in Level I.

327 (or any successor  provision) to the Federal Deposit  Insurance  Corporation

offices of such member in the United  States;  provided  that if, as a result of
any change in any law, rule or regulation, it is no longer possible to determine
the Assessment Rate as aforesaid,  then the Assessment Rate shall be such annual
rate as shall be determined by the Administrative Agent to

amendment  to any  provision  hereof  to  eliminate  the  effect  of any  change
occurring  after the date  hereof in GAAP or in the  application  thereof on the
operation of such  provision (or if the  Administrative  Agent  notifies Level 3
that the Required  Lenders request an amendment to any provision hereof for such
purpose),  regardless  of whether any such notice is given  before or after such
change  in GAAP or in the  application  thereof,  then such  provision  shall be
interpreted  on the basis of GAAP as in effect and  applied  immediately  before
such  change  shall have  become  effective  until such  notice  shall have been
withdrawn or such  provision  amended in accordance  herewith and (ii) no effect

foregoing  procedures.   Accordingly,   compliance  or  noncompliance  with  the
financial  covenants  in Article  VI  applicable  to Level 3 and the  Restricted
Subsidiaries will be based on combined financial  statements prepared to exclude
the PKSI Non-Telecom Business in accordance with the foregoing.  For purposes of
this  Agreement,  any  investment in or loan or advance to the PKSI  Non-Telecom
Business  funded other than out of the cash flows  attributable to such business
will be treated as and deemed to be an investment in an Unrestricted Subsidiary.
Notwithstanding  the  foregoing,  PKSI  will  be and so  long  as it  remains  a
Subsidiary  shall at all times remain a Restricted  Subsidiary  and a Subsidiary
Loan Party hereunder, and it (and all its assets and operations) will be subject
to the covenants and other terms and conditions of the Loan Documents applicable
to Restricted Subsidiaries and Subsidiary Loan Parties.


                                   ARTICLE II

                                   The Credits

                  SECTION 2.01. Commitments. Subject to the terms and conditions
set forth herein  (including,  without  limitation,  those set forth in Sections
4.01, 4.02 and 4.03 hereof), each Lender agrees (a) to make Tranche A Term Loans
to BTE  and  the  Interim  Borrower  from  time to time  during  the  Tranche  A
Availability Period in an aggregate principal amount not exceeding its Tranche A
Commitment,  (b) to make Tranche B Term Loans to BTE and the Interim Borrower on
the Effective Date in a principal  amount not exceeding its Tranche B Commitment
and (c) to make Revolving Loans to the RC Borrowers from time to time during the
Revolving  Availability  Period in an aggregate  principal  amount that will not
result in such Lender's  Revolving  Exposure  exceeding such Lender's  Revolving
Commitment;  provided,  that, on the Effective Date, the Borrowers must borrow a
minimum  aggregate  principal amount of (i) $200,000,000 of Tranche A Term Loans
and (ii)  $275,000,000  of  Tranche  B Term  Loans.  The  obligations  of the RC
Borrowers  under the Revolving  Facility  will be on a joint and several  basis.
Within the foregoing  limits and subject to the terms and  conditions  set forth
herein, the RC Borrowers may borrow, prepay and reborrow Revolving Loans. Except
as provided in Section 2.22 with respect to Corresponding  Loans, amounts repaid
in respect of Term Loans may not be reborrowed.

                  SECTION 2.02.  Loans and Borrowings.  (a)  Each
Loan (other than a Swingline Loan) shall be made as part of
a Borrowing consisting of Loans of the same Class and Type
made by the Lenders ratably in accordance with their

[NYCorp;929085.1:4459B:10/13/1999--4:01p]

<PAGE>


                                                                              44

respective  Commitments  of the applicable  Class.  The failure of any Lender to
make any Loan  required to be made by it shall not  relieve any other  Lender of
its  obligations  hereunder;  provided that the  Commitments  of the Lenders are
several and no Lender shall be  responsible  for any other  Lender's  failure to
make Loans as required.

                  (b) Subject to Section 2.14, each Revolving Borrowing and Term
Borrowing  shall be comprised  entirely of ABR Loans or Eurodollar  Loans as the
Borrowers  or the Interim  Borrower  may request in  accordance  herewith.  Each
Swingline  Loan  shall be an ABR Loan.  Each  Lender at its  option may make any
Eurodollar  Loan by causing any domestic or foreign  branch or Affiliate of such
Lender to make such Loan;  provided  that any  exercise of such option shall not
affect the  obligation  of the  Borrowers or the Interim  Borrower to repay such
Loan in accordance with the terms of this Agreement.

                  (c) At the  commencement  of  each  Interest  Period  for  any
Eurodollar Borrowing,  such Borrowing shall be in an aggregate amount that is an
integral multiple of $1,000,000 and not less than $10,000,000.  At the time that
each ABR Revolving  Borrowing is made,  such Borrowing  shall be in an aggregate
amount that is an integral multiple of $1,000,000 and not less than $10,000,000;
provided that an ABR Revolving  Borrowing may be in an aggregate  amount that is
equal to the entire unused balance of the total Revolving Commitments or that is
required to finance the  reimbursement  of an LC Disbursement as contemplated by
Section  2.05(e).  Each Swingline Loan shall be in an amount that is an integral
multiple  of  $1,000,000.  Borrowings  of more  than one Type and  Class  may be
outstanding at the same time;  provided that there shall not at any time be more
than a total of 20 Eurodollar Borrowings outstanding.

                  (d) Notwithstanding any other provision of this Agreement, the
Borrowers shall not be entitled to request,  or to elect to convert or continue,
any Borrowing if the Interest  Period  requested with respect  thereto would end
after the Revolving Maturity Date, Tranche A Maturity Date
or Tranche B Maturity Date, as applicable.

                  SECTION 2.03. Requests for Borrowings.  To request a Revolving
Borrowing  or Term  Borrowing,  a Borrower  (or Level 3 on behalf of a Borrower)
shall notify the  Administrative  Agent of such request by telephone  (a) in the
case of a Eurodollar  Borrowing,  not later than 1:00 p.m.,  New York City time,
three Business Days before the date of the proposed Borrowing or (b) in the case
of an ABR Borrowing, not later than 1:00 p.m., New York City time, one

Business Day before the date of the proposed  Borrowing;  provided that any such
notice of an ABR  Revolving  Borrowing  to finance  the  reimbursement  of an LC
Disbursement  as  contemplated  by Section  2.05(e)  may be given not later than
10:00 a.m., New York City time, on the date of the proposed Borrowing. Each such
telephonic  Borrowing  Request  shall be  irrevocable  and  shall  be  confirmed
promptly by hand delivery or telecopy to the  Administrative  Agent of a written
Borrowing Request in a form approved by the  Administrative  Agent and signed by
the applicable Borrower (or by Level 3 on its behalf).  Each such telephonic and
written Borrowing Request shall specify the following  information in compliance
with Section 2.02:

                  (i) whether the requested Borrowing is to be a
         Revolving Borrowing, Tranche A Term Borrowing or
         Tranche B Term Borrowing;

                  (ii) the aggregate amount of such Borrowing;

                  (iii) the date of such  Borrowing,  which  shall be a Business
         Day;

                  (iv)  whether such  Borrowing  is to be an ABR  Borrowing or a
         Eurodollar Borrowing;

                  (v)  in  the  case  of a  Eurodollar  Borrowing,  the  initial
         Interest  Period  to be  applicable  thereto,  which  shall be a period
         contemplated by the definition of the term "Interest Period"; and

                  (vi) the relevant  Borrower and the location and number of the
         Borrower's  account to which  funds are to be  disbursed,  which  shall
         comply with the requirements of Section 2.06.

If no election as to the Type of  Borrowing  is  specified,  then the  requested
Borrowing  shall be an ABR  Borrowing.  If no Interest  Period is specified with
respect to any requested  Eurodollar  Revolving  Borrowing,  then the applicable
Borrower  shall be deemed to have  selected  an  Interest  Period of one month's
duration.  Promptly  following receipt of a Borrowing Request in accordance with
this Section,  the Administrative  Agent shall advise each Lender of the details
thereof  and of the  amount  of  such  Lender's  Loan  to be made as part of the
requested Borrowing.

                  SECTION 2.04.  Swingline Loans.  (a)  Subject to
the terms and conditions set forth herein, the Swingline
Lender agrees to make Swingline  Loans to the RC Borrowers
from time to time during the Revolving Availability Period,

                                                                              46

in an aggregate principal amount at any time outstanding that will not result in
(i) the aggregate  principal  amount of outstanding  Swingline  Loans  exceeding
$50,000,000 or (ii) the sum of the total Revolving Exposures exceeding the total
Revolving Commitments;  provided that the Swingline Lender shall not be required
to make a Swingline Loan to refinance an outstanding  Swingline Loan. Within the
foregoing  limits and subject to the terms and conditions set forth herein,  the
Borrower may borrow, prepay and reborrow Swingline Loans.

                  (b) To request a Swingline Loan, an RC Borrower (or Level 3 on
its behalf) shall notify the  Administrative  Agent of such request by telephone
(confirmed by telecopy),  not later than 12:00 noon,  New York City time, on the
day of a proposed  Swingline  Loan.  Each such notice shall be  irrevocable  and
shall specify the  requested  date (which shall be a Business Day) and amount of
the requested Swingline Loan. The Administrative  Agent will promptly advise the
Swingline Lender of any such notice received from an RC Borrower.  The Swingline
Lender shall make each Swingline  Loan  available to the requesting  Borrower by
means of a credit to the  general  deposit  account  of such  Borrower  with the
Swingline  Lender  (or,  in the case of a  Swingline  Loan made to  finance  the
reimbursement  of  an  LC  Disbursement  as  provided  in  Section  2.06(e),  by
remittance  to the  Issuing  Bank) by 3:00  p.m.,  New York  City  time,  on the
requested date of such Swingline Loan.

                  (c) The  Swingline  Lender may by written  notice given to the
Administrative  Agent not later than  10:00  a.m.,  New York City  time,  on any
Business Day require the  Revolving  Lenders to acquire  participations  on such
Business Day in all or a portion of the Swingline Loans outstanding. Such notice
shall specify the aggregate amount of Swingline Loans in which Revolving Lenders
will participate. Promptly upon receipt of such notice, the Administrative Agent
will give notice  thereof to each  Revolving  Lender,  specifying in such notice
such  Lender's  Applicable  Percentage  of such  Swingline  Loan or Loans.  Each
Revolving Lender hereby absolutely and  unconditionally  agrees, upon receipt of
notice as provided above, to pay to the Administrative Agent, for the account of
the Swingline Lender, such Lender's Applicable Percentage of such Swingline Loan
or Loans.  Each Revolving Lender  acknowledges and agrees that its obligation to
acquire participations in Swingline Loans pursuant to this paragraph is absolute
and  unconditional  and shall not be  affected by any  circumstance  whatsoever,
including  the  occurrence  and   continuance  of  a  Default  or  reduction  or
termination of the Commitments, and that each such payment shall be made without
any offset, abatement,

                                                                              47

withholding or reduction whatsoever. Each Revolving Lender shall comply with its
obligation under this paragraph by wire transfer of immediately available funds,
in the same  manner as provided  in Section  2.06 with  respect to Loans made by
such Lender (and  Section  2.06 shall apply,  mutatis  mutandis,  to the payment
obligations  of the  Revolving  Lenders),  and the  Administrative  Agent  shall
promptly  pay to the  Swingline  Lender the  amounts so  received by it from the
Revolving Lenders.  The Administrative  Agent shall notify the relevant Borrower
of any participations in any Swingline Loan acquired pursuant to this paragraph,
and  thereafter  payments in respect of such Swingline Loan shall be made to the
Administrative  Agent and not to the Swingline  Lender.  Any amounts received by
the  Swingline  Lender  from an RC  Borrower  (or other  party on behalf of such
Borrower) in respect of a Swingline  Loan after receipt by the Swingline  Lender
of the proceeds of a sale of  participations  therein shall be promptly remitted
to the  Administrative  Agent; any such amounts  received by the  Administrative
Agent shall be promptly  remitted by the  Administrative  Agent to the Revolving
Lenders that shall have made their  payments  pursuant to this  paragraph and to
the  Swingline  Lender,   as  their  interests  may  appear.   The  purchase  of
participations  in a Swingline Loan pursuant to this paragraph shall not relieve
any RC Borrower of any default in the payment thereof.

                  SECTION 2.05. Letters of Credit.  (a) General.  Subject to the
terms and conditions set forth herein,  each of the RC Borrowers may request the
issuance  of  Letters  of  Credit  for its  own  account,  in a form  reasonably
acceptable  to the  Administrative  Agent and the Issuing  Bank, at any time and
from time to time during the Revolving  Availability Period. In the event of any
inconsistency  between the terms and  conditions of this Agreement and the terms
and conditions of any form of letter of credit  application  or other  agreement
submitted  by an RC Borrower  to, or entered  into by an RC Borrower  with,  the
Issuing Bank relating to any Letter of Credit,  the terms and conditions of this
Agreement  shall control.  Such terms and conditions of any such  application or
other  agreement  shall not, in any event,  contain any  operating  covenants or
restrictions,  provide for any  collateral not provided under the Loan Documents
or provide for the imposition of any fees (other than customary charges).

                  (b) Notice of Issuance, Amendment, Renewal, Extension; Certain
Conditions.  To request the  issuance  of a Letter of Credit (or the  amendment,
renewal or extension  of an  outstanding  Letter of Credit),  an RC Borrower (or
Level 3 on its behalf) shall hand deliver or telecopy (or transmit

                                                                              48

by electronic communication,  if arrangements for doing so have been approved by
the Issuing Bank) to the Issuing Bank and the  Administrative  Agent (reasonably
in advance of the requested date of issuance, amendment, renewal or extension) a
notice  requesting the issuance of a Letter of Credit, or identifying the Letter
of Credit  to be  amended,  renewed  or  extended,  and  specifying  the date of
issuance,  amendment,  renewal or extension (which shall be a Business Day), the
date on which  such  Letter  of Credit is to expire  (which  shall  comply  with
paragraph (c) of this  Section),  the amount of such Letter of Credit,  the name
and address of the  beneficiary  thereof and such other  information as shall be
necessary to prepare, amend, renew or extend such Letter of Credit. If requested
by the Issuing  Bank,  the  applicable  Borrower  also shall  submit a letter of
credit  application on the Issuing Bank's  standard form in connection  with any
request  for a Letter of Credit.  A Letter of Credit  shall be issued,  amended,
renewed or extended only if (and upon issuance,  amendment, renewal or extension
of each  Letter of Credit  the RC  Borrowers  shall be deemed to  represent  and
warrant  that),  after giving  effect to such  issuance,  amendment,  renewal or
extension (i) the LC Exposure  shall not exceed  $50,000,000  and (ii) the total
Revolving Exposures shall not exceed the total Revolving Commitments.

                  (c) Expiration  Date. Each Letter of Credit shall expire at or
prior to the close of business on the earlier of (i) the date one year after the
date of the issuance of such Letter of Credit (or, in the case of any renewal or
extension  thereof,  one year after such renewal or extension) and (ii) the date
that is five Business Days prior to the Revolving Maturity Date.

                  (d) Participations.  By the issuance of a Letter of Credit (or
an amendment to a Letter of Credit  increasing  the amount  thereof) and without
any further  action on the part of the Issuing Bank or the Lenders,  the Issuing
Bank hereby grants to each Revolving  Lender,  and each Revolving  Lender hereby
acquires from the Issuing Bank, a  participation  in such Letter of Credit equal
to such Lender's  Applicable  Percentage of the aggregate amount available to be
drawn under such Letter of Credit.  In  consideration  and in furtherance of the
foregoing, each Revolving Lender hereby absolutely and unconditionally agrees to
pay to the  Administrative  Agent,  for the  account of the Issuing  Bank,  such
Lender's Applicable  Percentage of each LC Disbursement made by the Issuing Bank
and not  reimbursed by the RC Borrowers on the date due as provided in paragraph
(e) of this Section, or of any reimbursement  payment required to be refunded to
the Borrowers for any reason. Each Lender acknowledges and agrees that its

                                                                              49

obligation to acquire  participations  pursuant to this  paragraph in respect of
Letters of Credit is absolute and unconditional and shall not be affected by any
circumstance  whatsoever,  including any amendment,  renewal or extension of any
Letter of Credit or the occurrence and  continuance of a Default or reduction or
termination of the Commitments, and that each such payment shall be made without
any offset, abatement, withholding or reduction whatsoever.

                  (e)  Reimbursement.  If the  Issuing  Bank  shall  make any LC
Disbursement in respect of a Letter of Credit,  the RC Borrowers shall reimburse
such LC  Disbursement by paying to the  Administrative  Agent an amount equal to
such LC Disbursement  not later than 12:00 noon, New York City time, on the date
that such LC Disbursement is made, if the relevant  Borrower shall have received
notice of such LC Disbursement  prior to 10:00 a.m., New York City time, on such
date, or, if such notice has not been received by the relevant Borrower prior to
such time on such date,  then not later than 12:00 noon,  New York City time, on
(i) the Business Day that such Borrower  receives such notice, if such notice is
received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii)
the Business Day immediately  following the day that such Borrower receives such
notice, if such notice is not received prior to such time on the day of receipt;
provided  that,  if such LC  Disbursement  is not  less  than  $10,000,000,  the
Borrower may,  subject to the conditions to borrowing set forth herein,  request
in  accordance  with Section 2.03 or 2.04 that such payment be financed  with an
ABR Revolving  Borrowing or Swingline  Loan in an equivalent  amount and, to the
extent so financed,  such  Borrower's  obligation  to make such payment shall be
discharged  and replaced by the resulting  ABR Revolving  Borrowing or Swingline
Loan. If such Borrower  fails to make such payment when due, the  Administrative
Agent shall notify each Revolving Lender of the applicable LC Disbursement,  the
amount  of  the  unreimbursed  LC  Disbursement  and  such  Lender's  Applicable
Percentage  thereof.  Promptly following receipt of such notice,  each Revolving
Lender shall pay to the  Administrative  Agent its Applicable  Percentage of the
unreimbursed  LC  Disbursement,  in the same manner as provided in Section  2.06
with respect to Loans made by such Lender (and Section 2.06 shall apply, mutatis
mutandis,  to  the  payment  obligations  of the  Revolving  Lenders),  and  the
Administrative  Agent  shall  promptly  pay to the  Issuing  Bank the amounts so
received by it from the Revolving  Lenders.  Promptly  following  receipt by the
Administrative  Agent of any payment from a Borrower pursuant to this paragraph,
the  Administrative  Agent shall distribute such payment to the Issuing Bank or,
to the extent that Revolving Lenders have made payments pursuant to

                                                                              50

this  paragraph  to  reimburse  the Issuing  Bank,  then to such Lenders and the
Issuing  Bank as their  interests  may appear.  Any payment  made by a Revolving
Lender  pursuant to this  paragraph  to  reimburse  the Issuing  Bank for any LC
Disbursement  (other than the funding of ABR Revolving Loans or a Swingline Loan
as contemplated  above) shall not constitute a Loan and shall not relieve the RC
Borrowers of their obligation to reimburse such LC Disbursement.

                  (f)  Obligations  Absolute.  The RC  Borrowers'  obligation to
reimburse LC Disbursements as provided in paragraph (e) of this Section shall be
absolute,  unconditional  and  irrevocable,  and shall be performed  strictly in
accordance  with the terms of this  Agreement  under  any and all  circumstances
whatsoever and irrespective of (i) any lack of validity or enforceability of any
Letter of Credit or this Agreement,  or any term or provision therein,  (ii) any
draft or other document presented under a Letter of Credit proving to be forged,
fraudulent  or invalid in any respect or any  statement  therein being untrue or
inaccurate  in any respect,  (iii) payment by the Issuing Bank under a Letter of
Credit  against  presentation  of a draft or other document that does not comply
with the terms of such Letter of Credit, or (iv) any other event or circumstance
whatsoever,  whether or not similar to any of the foregoing, that might, but for
the provisions of this Section, constitute a legal or equitable discharge of, or
provide a right of setoff  against,  the RC  Borrowers'  obligations  hereunder.
Neither the  Administrative  Agent, the Lenders nor the Issuing Bank, nor any of
their Related Parties,  shall have any liability or  responsibility by reason of
or in  connection  with the  issuance or transfer of any Letter of Credit or any
payment or failure to make any payment  thereunder  (irrespective  of any of the
circumstances  referred to in the preceding sentence),  or any error,  omission,
interruption,  loss or delay in transmission or delivery of any draft, notice or
other  communication  under or relating to any Letter of Credit  (including  any
document required to make a drawing thereunder),  any error in interpretation of
technical terms or any consequence arising from causes beyond the control of the
Issuing Bank;  provided that the foregoing  shall not be construed to excuse the
Issuing  Bank from  liability  to the RC  Borrowers  to the extent of any direct
damages (as  opposed to  consequential  damages,  claims in respect of which are
hereby  waived by the RC Borrowers to the extent  permitted by  applicable  law)
suffered by the RC Borrowers  that are caused by the Issuing  Bank's  failure to
exercise care when  determining  whether  drafts and other  documents  presented
under a Letter of Credit  comply  with the terms  thereof.  The  parties  hereto
expressly agree that, in the absence of gross negligence or

[NYCorp;929085.1:4459B:10/13/1999--4:01p]

<PAGE>


                                                                              51

wilful  misconduct  on the part of the Issuing Bank (as finally  determined by a
court of  competent  jurisdiction),  the  Issuing  Bank  shall be deemed to have
exercised care in each such  determination.  In furtherance of the foregoing and
without limiting the generality thereof, the parties agree that, with respect to
documents  presented which appear on their face to be in substantial  compliance
with the  terms  of a Letter  of  Credit,  the  Issuing  Bank  may,  in its sole
discretion,   either  accept  and  make  payment  upon  such  documents  without
responsibility   for  further   investigation,   regardless  of  any  notice  or
information  to the  contrary,  or refuse to accept and make  payment  upon such
documents if such documents are not in strict  compliance with the terms of such
Letter of Credit.

                  (g) Disbursement Procedures.  The Issuing Bank shall, promptly
following its receipt thereof,  examine all documents  purporting to represent a
demand for payment  under a Letter of Credit.  The Issuing  Bank shall  promptly
notify  the  Administrative   Agent  and  the  relevant  Borrower  by  telephone
(confirmed  by telecopy) of such demand for payment and whether the Issuing Bank
has made or will make an LC Disbursement  thereunder;  provided that any failure
to give or delay in giving such notice  shall not relieve  such  Borrower of its
obligation to reimburse the Issuing Bank and the Revolving  Lenders with respect
to any such LC Disbursement.

                  (h) Interim  Interest.  If the Issuing  Bank shall make any LC
Disbursement, then, unless the RC Borrowers shall reimburse such LC Disbursement
in full on the date such LC  Disbursement  is made,  the unpaid  amount  thereof
shall  bear  interest,  for  each  day  from  and  including  the  date  such LC
Disbursement  is made to but excluding the date that the RC Borrowers  reimburse
such LC  Disbursement,  at the rate per annum then  applicable  to ABR Revolving
Loans; provided that, if the RC Borrowers fail to reimburse such LC Disbursement
when due pursuant to paragraph (e) of this Section,  then Section  2.14(c) shall
apply.  Interest  accrued pursuant to this paragraph shall be for the account of
the Issuing Bank,  except that interest accrued on and after the date of payment
by any Revolving  Lender  pursuant to paragraph (e) of this Section to reimburse
the  Issuing  Bank shall be for the account of such Lender to the extent of such
payment.

                  (i)  Replacement  of the Issuing Bank. The Issuing Bank may be
replaced  at any time by written  agreement  among  Level 3, the  Administrative
Agent,  the  replaced   Issuing  Bank  and  the  successor   Issuing  Bank.  The
Administrative Agent shall notify the Lenders of any such replacement of the

<PAGE>


                                                                              52

Issuing Bank. At the time any such replacement  shall become  effective,  the RC
Borrowers  shall pay all unpaid fees  accrued  for the  account of the  replaced
Issuing Bank pursuant to Section  2.14(b).  From and after the effective date of
any such  replacement,  (i) the successor Issuing Bank shall have all the rights
and obligations of the Issuing Bank under this Agreement with respect to Letters
of  Credit  to be  issued  thereafter  and (ii)  references  herein  to the term
"Issuing  Bank" shall be deemed to refer to such  successor  or to any  previous
Issuing  Bank,  or to such  successor  and all previous  Issuing  Banks,  as the
context shall require.  After the replacement of an Issuing Bank hereunder,  the
replaced Issuing Bank shall remain a party hereto and shall continue to have all
the rights and  obligations of an Issuing Bank under this Agreement with respect
to Letters of Credit  issued by it prior to such  replacement,  but shall not be
required to issue additional Letters of Credit.

                  (j) Cash  Collateralization.  If any  Event of  Default  shall
occur and be continuing,  on the Business Day that Level 3 receives  notice from
the  Administrative  Agent upon the instructions of the Required Lenders (or, if
the  maturity  of the  Loans has been  accelerated,  Revolving  Lenders  with LC
Exposure  representing  greater than 50% of the total LC Exposure) demanding the
deposit of cash collateral  pursuant to this  paragraph,  the RC Borrowers shall
deposit  in an  account  with  the  Administrative  Agent,  in the  name  of the
Administrative Agent and for the benefit of the Lenders, an amount in cash equal
to the LC Exposure as of such date plus any accrued and unpaid interest thereon;
provided  that the  obligation  to deposit  such cash  collateral  shall  become
effective  immediately,  and  such  deposit  shall  become  immediately  due and
payable,  without demand or other notice of any kind, upon the occurrence of any
Event of Default with respect to Level 3 or any RC Borrower  described in clause
(h) or (i) of Article VII. Each such deposit shall be held by the Administrative
Agent as collateral for the payment and performance of the obligations of the RC
Borrowers under this Agreement.  The  Administrative  Agent shall have exclusive
dominion and control,  including the exclusive  right of  withdrawal,  over such
account.  Other than any interest  earned on the  investment of such deposits in
readily  marketable  Permitted  Investments  maturing  in not more than 60 days,
which Permitted Investments shall be made at the direction of Level 3 and at the
RC Borrowers' risk and expense, such deposits shall not bear interest.  Interest
or profits, if any, on such investments shall accumulate in such account. Moneys
in such account  shall be applied by the  Administrative  Agent to reimburse the
Issuing Bank for LC

                                                                              53

Disbursements  for which it has not been  reimbursed  and,  to the extent not so
applied, shall be held for the satisfaction of the reimbursement  obligations of
the RC  Borrowers  for the LC Exposure  at such time or, if the  maturity of the
Loans has been accelerated (but subject to the consent of Revolving Lenders with
LC Exposure representing greater than 50% of the total LC Exposure),  be applied
to  satisfy  other  obligations  of the  Borrowers  (including  BTE)  under this
Agreement. If an RC Borrower is required to provide an amount of cash collateral
hereunder as a result of the occurrence of an Event of Default,  such amount (to
the extent not applied as aforesaid) shall be returned to the RC Borrower within
three Business Days after all Events of Default have been cured or waived.

                  SECTION 2.06.  Funding of Borrowings.  (a)  Each
                                 ----------------------
Lender shall make each Loan to be made by it hereunder on
the proposed date thereof by wire transfer of immediately
available funds by 12:00 noon, New York City time, to the
account of the Administrative Agent most recently designated
by it for such purpose by notice to the Lenders; provided
                                                 --------
that Swingline Loans shall be made as provided in
Section 2.04.  The Administrative Agent will make such Loans
available to the appropriate Borrower by promptly (but in no
event later than 2:00 p.m., New York City time) crediting
the amounts so received, in like funds, to an account of
such Borrower maintained with the Administrative Agent in
New York City and designated in the applicable Borrowing
Request; provided that ABR Revolving Loans made to finance
         --------
the reimbursement of an LC Disbursement as provided in
Section 2.05(e) shall be remitted by the Administrative
Agent to the Issuing Bank.

                  (b) Unless the Administrative Agent shall have received notice
from a Lender prior to the proposed date of any Borrowing  that such Lender will
not make  available  to the  Administrative  Agent such  Lender's  share of such
Borrowing,  the  Administrative  Agent may assume that such Lender has made such
share  available on such date in accordance  with  paragraph (a) of this Section
and may, in reliance upon such  assumption,  make  available to the  appropriate
Borrower a corresponding amount. In such event, if a Lender has not in fact made
its share of the applicable  Borrowing  available to the  Administrative  Agent,
then the applicable Lender and the relevant  Borrower  severally agree to pay to
the  Administrative  Agent  forthwith on demand such  corresponding  amount with
interest  thereon,  for each day from and including the date such amount is made
available  to  such  Borrower  to but  excluding  the  date  of  payment  to the
Administrative  Agent,  at (i) in the case of such  Lender,  the  greater of the
Federal Funds Effective Rate and a rate

                                                                              54

determined by the Administrative Agent in accordance with banking industry rules
on interbank  compensation  or (ii) in the case of such  Borrower,  the interest
rate  applicable  to  ABR  Loans.  If  such  Lender  pays  such  amount  to  the
Administrative  Agent,  then such amount shall  constitute  such  Lender's  Loan
included in such Borrowing.

                  SECTION 2.07. Interest Elections. (a) Each Revolving Borrowing
and Term  Borrowing  initially  shall be of the Type specified in the applicable
Borrowing  Request  and, in the case of a  Eurodollar  Borrowing,  shall have an
initial Interest Period as specified in such Borrowing  Request.  Thereafter,  a
Borrower may elect to convert such  Borrowing to a different Type or to continue
such  Borrowing and, in the case of a Eurodollar  Borrowing,  may elect Interest
Periods  therefor,  all as provided in this  Section.  The  Borrowers  may elect
different options with respect to different portions of the affected  Borrowing,
in which case each such  portion  shall be allocated  ratably  among the Lenders
holding the Loans comprising such Borrowing,  and the Loans comprising each such
portion shall be considered a separate  Borrowing.  This Section shall not apply
to Swingline Borrowings, which may not be converted or continued.

                  (b)  To  make  an  election  pursuant  to  this  Section,  the
applicable  Borrower (or Level 3 on its behalf) shall notify the  Administrative
Agent of such  election by telephone by the time that a Borrowing  Request would
be required  under  Section  2.03 if the  Borrower  were  requesting a Revolving
Borrowing of the Type  resulting  from such election to be made on the effective
date of such election.  Each such telephonic  Interest Election Request shall be
irrevocable and shall be confirmed  promptly by hand delivery or telecopy to the
Administrative  Agent of a written Interest  Election Request in a form approved
by the Administrative Agent and signed by the applicable Borrower (or Level 3 on
its behalf).

                  (c) Each  telephonic  and written  Interest  Election  Request
shall specify the following information in compliance with Section 2.02:

                  (i) the  Borrowing  to which such  Interest  Election  Request
         applies  and, if  different  options are being  elected with respect to
         different  portions  thereof,  the portions  thereof to be allocated to
         each resulting Borrowing (in which case the information to be specified
         pursuant to clauses  (iii) and (iv) below shall be  specified  for each
         resulting Borrowing);

                                                                              55

                  (ii) the effective  date of the election made pursuant to such
         Interest Election Request, which shall be a Business Day;

                  (iii)  whether  the  resulting  Borrowing  is  to  be  an  ABR
         Borrowing or a Eurodollar Borrowing; and

                  (iv) if the resulting Borrowing is a Eurodollar Borrowing, the
         Interest  Period to be  applicable  thereto after giving effect to such
         election, which shall be a period contemplated by the definition of the
         term "Interest Period".

If any such Interest  Election Request requests a Eurodollar  Borrowing but does
not specify an Interest Period,  then the requesting Borrower shall be deemed to
have selected an Interest Period of one month's duration.

                  (d)  Promptly   following  receipt  of  an  Interest  Election
Request,  the  Administrative  Agent  shall  advise  each  Lender of the details
thereof and of such Lender's portion of each resulting Borrowing.

                  (e) If a Borrower fails to deliver a timely Interest  Election
Request with respect to a Eurodollar  Borrowing prior to the end of the Interest
Period  applicable  thereto,  then,  unless such Borrowing is repaid as provided
herein,  at the end of such Interest Period such Borrowing shall be converted to
an ABR Borrowing.  Notwithstanding any contrary provision hereof, if an Event of
Default has occurred and is  continuing  and the  Administrative  Agent,  at the
request of the Required Lenders, so notifies the Borrowers,  then, so long as an
Event of Default is continuing (i) no outstanding  Borrowing may be converted to
or continued as a Eurodollar  Borrowing (except for a Eurodollar  Borrowing with
an  Interest  Period of one  month)  and (ii)  unless  repaid,  each  Eurodollar
Borrowing  shall be either (x) converted to an ABR Borrowing or (y) continued as
a Eurodollar  Borrowing  with an Interest  Period of one month at the end of the
Interest Period applicable thereto.

                  SECTION 2.08.  Termination and Reduction of  Commitments.  (a)
Unless  previously  terminated,  (i) the Tranche A Commitments will terminate at
5:00 p.m.,  New York City time,  on the Tranche A Commitment  Termination  Date,
(ii) the Tranche B Commitments shall terminate at 5:00 p.m., New York City time,
on the Effective Date and (iii) the Revolving Commitments shall terminate on the
Revolving Maturity Date.

                  (b)  Level 3 may at any time  terminate,  or from time to time
reduce,  the  Commitments of any Class;  provided that (i) each reduction of the
Commitments  of any Class shall be in an amount that is an integral  multiple of
$1,000,000 and not less than $10,000,000, (ii) the Revolving Commitments may not
be  terminated  or reduced  unless all Term Loans have been paid in full and all
commitments to make Term Loans have expired or been terminated and (iii) Level 3
shall not terminate or reduce the Revolving  Commitments if, after giving effect
to any concurrent  prepayment of the Revolving  Loans in accordance with Section
2.11,  the sum of the  Revolving  Exposures  would  exceed  the total  Revolving
Commitments.

                  (c)  Level 3 shall  notify  the  Administrative  Agent  of any
election to  terminate or reduce the  Commitments  under  paragraph  (b) of this
Section  at  least  three  Business  Days  prior to the  effective  date of such
termination  or  reduction,  specifying  such  election and the  effective  date
thereof.  Promptly  following receipt of any notice,  the  Administrative  Agent
shall advise the Lenders of the contents thereof. Each notice delivered by Level
3 pursuant  to this  Section  shall be  irrevocable;  provided  that a notice of
termination  of the  Revolving  Commitments  delivered by Level 3 may state that
such notice is conditioned upon the effectiveness of other credit facilities, in
which  case  such   notice  may  be  revoked  by  Level  3  (by  notice  to  the
Administrative  Agent  on or  prior  to the  specified  effective  date) if such
condition is not satisfied.  Any  termination or reduction of the Commitments of
any Class shall be permanent.  Each  reduction of the  Commitments  of any Class
shall be made  ratably  among the Lenders in  accordance  with their  respective
Commitments of such Class.

                  SECTION 2.09. Repayment of Loans; Evidence of Debt. (a) The RC
Borrowers hereby jointly and severally unconditionally promise to pay (i) to the
Administrative  Agent for the account of each  Lender the then unpaid  principal
amount of each  Revolving  Loan of such Lender on the Revolving  Maturity  Date,
(ii) to the Administrative  Agent for the account of each Lender the then unpaid
principal  amount of each Term Loan of such Lender as  provided in Section  2.10
and (iii) to the  Swingline  Lender  the then  unpaid  principal  amount of each
Swingline Loan on the earlier of the Revolving  Maturity Date and the first date
after  such  Swingline  Loan is made that is the 15th or last day of a  calendar
month and is at least five  Business  Days after  such  Swingline  Loan is made;
provided  that on each date that a Revolving  Borrowing  is made,  the  Borrower
shall repay all Swingline Loans that were outstanding on the date such Borrowing
was requested.

                  (b) Each Lender shall  maintain in  accordance  with its usual
practice an account or accounts evidencing the indebtedness of each Borrower and
the  Interim  Borrower  to such  Lender  resulting  from  each Loan made by such
Lender, including the amounts of principal and interest payable and paid to such
Lender from time to time hereunder.

                  (c) The Administrative  Agent shall maintain accounts in which
it shall record (i) the amount of each Loan made  hereunder,  the Class and Type
thereof  and the  Interest  Period  applicable  thereto,  (ii) the amount of any
principal  or interest  due and  payable or to become due and  payable  from the
Borrowers or the Interim  Borrower to each Lender hereunder and (iii) the amount
of any sum received by the Administrative Agent hereunder for the account of the
Lenders and each Lender's share thereof.

                  (d) The entries  made in the accounts  maintained  pursuant to
paragraph  (b) or (c) of this  Section  shall be  prima  facie  evidence  of the
existence and amounts of the  obligations  recorded  therein;  provided that the
failure of any Lender or the  Administrative  Agent to maintain such accounts or
any error therein shall not in any manner affect the  obligation of any Borrower
or the Interim  Borrower to repay the Loans in accordance with the terms of this
Agreement.

                  (e) Any Lender may request  that Loans of any Class made by it
be evidenced by a promissory  note. In such event,  the relevant  Borrower shall
prepare,  execute and deliver to such Lender a  promissory  note  payable to the
order of such Lender (or, if requested  by such  Lender,  to such Lender and its
registered  assigns)  and  in a  form  approved  by  the  Administrative  Agent.
Thereafter,  the Loans evidenced by such  promissory  note and interest  thereon
shall at all times  (including  after  assignment  pursuant to Section  9.04) be
represented by one or more promissory notes in such form payable to the order of
the payee named therein (or, if such  promissory  note is a registered  note, to
such payee and its registered assigns).

                  SECTION  2.10.  Automatic  Revolving  Commitment   Reductions;
Amortization of Term Loans. (a) The aggregate  amount of the Lenders'  Revolving
Commitments  shall  automatically  and  permanently  reduce  in  14  consecutive
quarterly  reductions  commencing  on March 31, 2004 and a  fifteenth  and final
reduction on the Revolving  Maturity  Date, in each case in the amount set forth
opposite such reduction below:

                  (e) To the extent not previously  paid, (i) all Tranche A Term
Loans  (other  than  Interim  Loans)  shall be due and  payable on the Tranche A
Maturity  Date,  (ii) all  Tranche B Term Loans  shall be due and payable on the
Tranche B Maturity  Date,  (iii) all  Tranche A Interim  Loans  shall be due and
payable  on the  Tranche A Interim  Loan  Maturity  Date and (iv) all  Tranche B
Interim  Loans shall be due and payable on the Tranche B Interim  Loan  Maturity
Date.

                  (f) If the  initial  aggregate  amount  of the  Lenders'  Term
Commitments of either Class exceeds the aggregate principal amount of Term Loans
of such  Class that are made  during the  Tranche A  Availability  Period,  with
respect to Tranche A Loans,  or on the Effective  Date with respect to Tranche B
Loans or if the aggregate amount of Tranche A Interim Loans or Tranche B Interim
Loans  exceeds the amount of such  Interim  Loans that are repaid on or prior to
the Tranche A Interim Loan  Maturity Date or the Tranche B Interim Loan Maturity
Date in connection with the making of simultaneous Corresponding Loans, then the
scheduled  repayments  of Term  Borrowings  of Tranche A Term Loans or Tranche B
Term Loans (in each case,  other than Interim Loans) to be made pursuant to this
Section  shall be reduced  ratably by an aggregate  amount equal to such excess.
Any prepayment of a Term Borrowing of either Class (other than any prepayment of
Interim Loans) shall be applied to reduce the subsequent scheduled repayments of
the Term Borrowings of such Class (other than Interim Loans) to be made pursuant
to this Section ratably.

                  (g) Prior to any  repayment of any Term  Borrowings  of either
Class hereunder, the relevant Borrowers shall select the Borrowing or Borrowings
of the applicable Class to be repaid and shall notify the  Administrative  Agent
by telephone (confirmed by telecopy) of such selection not later than 1:00 p.m.,
New York City  time,  three  Business  Days  before the  scheduled  date of such
repayment; provided that each repayment of Term Borrowings of either Class shall
be applied to repay any outstanding ABR Term Borrowings of such Class before any
other  Borrowings of such Class.  Each repayment of a Borrowing shall be applied
ratably  to the Loans  included  in the  repaid  Borrowing.  Repayments  of Term
Borrowings shall be accompanied by accrued interest on the amount repaid.

                  SECTION 2.11.  Prepayment of Loans.  (a)  The
Borrowers shall have the right at any time and from time to

                                                                              61

time to prepay any Borrowing in whole or in part, subject to
the requirements of this Section.

                  (b) In the event and on each  occasion  that any Net  Proceeds
are  received  by or on  behalf  of  Level  3, any  Borrower  or any  Restricted
Subsidiary in respect of any Prepayment Event, the Equipment Borrowers (or Level
3 on behalf of the Equipment  Borrowers)  and Level 3 shall,  immediately  after
such Net  Proceeds  are  received,  prepay Term  Borrowings  (other than Interim
Borrowings) and Incremental Borrowings,  if any, in an aggregate amount equal to
such Net Proceeds.

                  (c)  Following  the end of each fiscal  year of the  Borrower,
commencing  with the fiscal year ending  December 31, 2003,  the Borrower  shall
prepay Term  Borrowings  and  Incremental  Borrowings,  if any, in an  aggregate
amount equal to 50% of Excess Cash Flow for such fiscal year; provided, however,
that no prepayment pursuant to this paragraph (c) shall be required on and after
the first date that the Leverage Ratio is less than 5.0 to 1.0 at the end of two
consecutive fiscal quarters. Each prepayment pursuant to this paragraph shall be
made on or before the date on which financial  statements are delivered pursuant
to Section  5.01 with  respect to the fiscal year for which  Excess Cash Flow is
being  calculated (and in any event within 120 days after the end of such fiscal
year).

                  (d)  Prior  to  any  optional  or  mandatory   prepayment   of
Borrowings  hereunder,  the relevant  Borrower (or Level 3 on its behalf)  shall
select  the  Borrowing  or  Borrowings  to be  prepaid  and shall  specify  such
selection in the notice of such  prepayment  pursuant to  paragraph  (e) of this
Section;  provided  that each  prepayment  of  Borrowings  of any Class shall be
applied to prepay ABR  Borrowings  of such Class before any other  Borrowings of
such  Class.  In the  event of any  optional  or  mandatory  prepayment  of Term
Borrowings  (other than Interim Loans) or Incremental  Borrowings made at a time
when Term Borrowings  (other than Interim Loans) and  Incremental  Borrowings of
more than one Class remain outstanding, the relevant Borrowers shall select Term
Borrowings and Incremental Borrowings to be prepaid so that the aggregate amount
of such  prepayment is allocated  between the Tranche A Term  Borrowings  (other
than Interim Loans),  Tranche B Term  Borrowings  (other than Interim Loans) and
Incremental  Borrowings  pro rata  based on the  aggregate  principal  amount of
outstanding  Borrowings  of each such  Class;  provided  that (i) in the case of
mandatory  prepayments,  only  Tranche  A Term  Borrowings  and  Tranche  B Term
Borrowings  that are not Interim Loans will be subject to  prepayment,  and (ii)
any Tranche B Lender may elect, by

notice to the Administrative Agent by telephone (confirmed by telecopy) at least
one Business Day prior to the prepayment  date, to decline all or any portion of
any  prepayment of its Tranche B Term Loans pursuant to this Section (other than
an optional prepayment pursuant to paragraph (a) of this Section,  which may not
be declined),  in which case the aggregate  amount of the prepayment  that would
have been  applied to prepay  Tranche B Term Loans but was so declined  shall be
applied  to prepay  Tranche  A Term  Borrowings.  In the  event of any  optional
prepayment  of Interim  Loans (other than in  connection  with the  simultaneous
borrowing by BTE of  Corresponding  Loans) made at a time when Interim  Loans of
more than one Class  remain  outstanding,  the  Interim  Borrower  shall  select
Borrowings of Interim  Loans to be prepaid so that the aggregate  amount of such
prepayment  is  allocated  between  the  Tranche A Interim  Loans and  Tranche B
Interim  Loans pro rata based on the aggregate  principal  amounts  thereof.  No
optional  prepayments  of  Revolving  Loans  may be made  (other  than  optional
prepayments of Revolving  Loans without a  corresponding  reduction in Revolving
Commitments) unless all Term Loans have been paid in full and all commitments to
make Term Loans have expired or been terminated.

          (e) The relevant  Borrower (or Level 3 on its behalf) shall notify the
Administrative  Agent (and, in the case of prepayment of a Swingline  Loan,  the
Swingline  Lender)  by  telephone  (confirmed  by  telecopy)  of any  prepayment
hereunder (i) in the case of prepayment of a Eurodollar Revolving Borrowing, not
later than 1:00 p.m., New York City time, three Business Days before the date of
prepayment,  (ii) in the case of prepayment of an ABR Revolving  Borrowing,  not
later than 1:00 p.m.,  New York City time,  one  Business Day before the date of
prepayment  or (iii) in the case of prepayment  of a Swingline  Loan,  not later
than 12:00 noon, New York City time, on the date of prepayment. Each such notice
shall be irrevocable and shall specify the prepayment date, the principal amount
of each  Borrowing  or  portion  thereof  to be  prepaid  and,  in the case of a
mandatory  prepayment,  a reasonably detailed  calculation of the amount of such
prepayment;  provided  that,  if a notice  of  optional  prepayment  is given in
connection with a conditional notice of termination of the Revolving Commitments
as  contemplated  by Section 2.08, then such notice of prepayment may be revoked
if such  notice of  termination  is revoked in  accordance  with  Section  2.08.
Promptly  following  receipt of any such notice  (other  than a notice  relating
solely to Swingline Loans), the Administrative Agent shall advise the Lenders of
the contents  thereof.  Each partial  prepayment of any Borrowing shall be in an
amount that would be permitted in the case of

                                                                              63

an advance of a Borrowing of the same Type as provided in Section  2.02,  except
as necessary to apply fully the required amount of a mandatory prepayment.  Each
prepayment of a Borrowing  shall be applied ratably to the Loans included in the
prepaid  Borrowing.  Prepayments shall be accompanied by accrued interest to the
extent required by Section 2.14.

                  SECTION 2.12. Tranche B Facility Prepayment Fee. Voluntary and
mandatory payments or prepayments of Tranche B Term Loans (including payments or
prepayments of Tranche B Interim Loans, other than in connection with the making
of  simultaneous  Corresponding  Loans,  as  contemplated  by Section  2.22) and
repayments of Tranche B Term Loans as a result of acceleration  upon an Event of
Default  consisting of the occurrence of a Change in Control,  in each case made
prior to the third  anniversary of the Effective  Date,  shall be accompanied by
payment of a prepayment fee as follows:

                  (A)      if such  prepayment or repayment is made on or before
                           the first  anniversary  of the Effective  Date, a fee
                           equal  to 3% of the  amount  or  such  prepayment  or
                           repayment;

                  (B)      if such  prepayment  or repayment is made  thereafter
                           but  on or  before  the  second  anniversary  of  the
                           Effective  Date,  a fee equal to 2% of the  amount of
                           such prepayment or repayment; and

                  (C)      if such  prepayment  or  repayment  is made after the
                           second  anniversary  of the Effective  Date but on or
                           before the third anniversary of the Effective Date, a
                           fee equal to 1% of the amount of such  prepayment  or
                           repayment.

                  SECTION  2.13.  Fees.  (a) BTE,  in the case of the  Tranche A
Commitments  and the Tranche B  Commitments,  and the RC Borrowers,  jointly and
severally,  in  the  case  of the  Revolving  Commitments,  agree  to pay to the
Administrative  Agent for the account of each  Lender a  commitment  fee,  which
shall accrue at the Applicable Commitment Fee Rate on the daily unused amount of
each  Commitment  of such Lender  during the period from and  including the date
hereof to but excluding the date on which such  Commitment  terminates.  Accrued
commitment  fees shall be  payable  in  arrears on the last day of March,  June,
September  and  December  of each  year and on the date on  which  the  relevant
Commitment terminates, commencing on the first such date to occur after the date
hereof. All commitment fees shall be computed on the basis of a year of 360 days
and shall be payable for the actual

number of days elapsed (including the first day but excluding the last day). For
purposes of computing commitment fees with respect to Revolving  Commitments,  a
Revolving Commitment of a Lender shall be deemed to be used to the extent of the
outstanding  Revolving  Loans and LC Exposure of such Lender (and the  Swingline
Exposure of such Lender shall be disregarded for such purpose).

                  (b) The RC Borrowers,  jointly and severally, agree to pay (i)
to the  Administrative  Agent  for  the  account  of  each  Revolving  Lender  a
participation fee with respect to its participations in Letters of Credit, which
shall accrue at the same  Applicable  Rate as interest on  Eurodollar  Revolving
Loans on the daily amount of such  Lender's LC Exposure  (excluding  any portion
thereof  attributable to unreimbursed LC  Disbursements)  during the period from
and including the Effective Date to but excluding the later of the date on which
such Lender's Revolving Commitment  terminates and the date on which such Lender
ceases to have any LC  Exposure,  and (ii) to the Issuing  Bank a fronting  fee,
which shall accrue at the rate or rates per annum separately agreed upon between
Level 3 and the  Issuing  Bank on the  average  daily  amount of the LC Exposure
(excluding any portion thereof  attributable  to unreimbursed LC  Disbursements)
during the period from and  including  the  Effective  Date to but excluding the
later of the date of  termination of the Revolving  Commitments  and the date on
which there ceases to be any LC Exposure, as well as the Issuing Bank's standard
fees with respect to the issuance, amendment, renewal or extension of any Letter
of Credit or processing of drawings thereunder.  Participation fees and fronting
fees accrued  through and including the last day of March,  June,  September and
December of each year shall be payable on the third  Business Day following such
last day,  commencing on the first such date to occur after the Effective  Date;
provided  that all such fees shall be payable on the date on which the Revolving
Commitments  terminate  and any such fees  accruing  after the date on which the
Revolving  Commitments  terminate  shall be payable  on  demand.  Any other fees
payable to the Issuing Bank pursuant to this  paragraph  shall be payable within
10 days after demand. All participation fees and fronting fees shall be computed
on the basis of a year of 360 days and shall be payable for the actual number of
days elapsed (including the first day but excluding the last day).

                  (c)   Level  3  and  the   Borrowers   agree  to  pay  to  the
Administrative  Agent,  for its own account,  fees payable in the amounts and at
the times separately agreed upon with the Administrative Agent.

                  (d) All fees payable hereunder shall be paid on the dates due,
in immediately  available funds, to the Administrative  Agent (or to the Issuing
Bank,  in the  case of fees  payable  to it) for  distribution,  in the  case of
commitment fees and participation  fees, to the Lenders entitled  thereto.  Fees
paid shall not be refundable under any circumstances.

                  SECTION 2.14.  Interest.  (a)  The Loans
comprising each ABR Borrowing (including each Swingline
Loan) shall bear interest at the Alternate Base Rate plus
the Applicable Rate.

                  (b) The Loans comprising each Eurodollar  Borrowing shall bear
interest at the LIBO Rate for the Interest  Period in effect for such  Borrowing
plus the Applicable Rate.

                  (c)  Notwithstanding  the  foregoing,  if any  principal of or
interest on any Loan or any fee or other  amount  payable by any Borrower or the
Interim  Borrower  hereunder is not paid when due,  whether at stated  maturity,
upon acceleration or otherwise,  such overdue amount shall bear interest,  after
as well as  before  judgment,  at a rate per  annum  equal to (i) in the case of
overdue  principal of any Loan,  2% plus the rate  otherwise  applicable to such
Loan as provided in the preceding paragraphs of this Section or (ii) in the case
of any other  amount,  2% plus the rate  applicable  to ABR  Revolving  Loans as
provided in paragraph (a) of this Section.

                  (d) Accrued  interest on each Loan shall be payable in arrears
on each Interest Payment Date for such Loan and, in the case of Revolving Loans,
upon  termination  of the  Revolving  Commitments;  provided  that (i)  interest
accrued  pursuant to paragraph  (c) of this Section  shall be payable on demand,
(ii) in the event of any  repayment  or  prepayment  of any Loan  (other  than a
prepayment  of an  ABR  Revolving  Loan  prior  to  the  end  of  the  Revolving
Availability Period), accrued interest on the principal amount repaid or prepaid
shall be payable on the date of such  repayment or  prepayment  and (iii) in the
event of any conversion of any  Eurodollar  Loan prior to the end of the current
Interest Period therefor,  accrued interest on such Loan shall be payable on the
effective date of such conversion.

                  (e) All interest hereunder shall be computed on the basis of a
year of 360 days,  except that  interest  computed by reference to the Alternate
Base Rate at times when the Alternate Base Rate is based on the Prime Rate

shall  be  computed  on the  basis  of a year of 365 days (or 366 days in a leap
year),  and in each case shall be payable for the actual  number of days elapsed
(including the first day but excluding the last day).  The applicable  Alternate
Base Rate or LIBO Rate shall be determined by the Administrative Agent, and such
determination shall be conclusive absent manifest error.

                  SECTION 2.15.  Alternate Rate of Interest.  If
prior to the commencement of any Interest Period for a
Eurodollar Borrowing:

                  (a) the Administrative  Agent determines (which  determination
         shall be conclusive absent manifest error) that adequate and reasonable
         means do not exist  for  ascertaining  the LIBO Rate for such  Interest
         Period; or

                  (b)  the  Administrative  Agent  is  advised  by the  Required
         Lenders that the LIBO Rate for such Interest Period will not adequately
         and fairly  reflect the cost to such  Lenders of making or  maintaining
         their Loans included in such Borrowing for such Interest Period;

then the  Administrative  Agent  shall  give  notice  thereof to Level 3 and the
Lenders by  telephone  or telecopy as promptly as  practicable  thereafter  and,
until  the  Administrative  Agent  notifies  Level 3 and the  Lenders  that  the
circumstances  giving  rise to such  notice no longer  exist,  (i) any  Interest
Election   Request  that  requests  the  conversion  of  any  Borrowing  to,  or
continuation  of any Borrowing as, a Eurodollar  Borrowing  shall be ineffective
and  (ii)  if any  Borrowing  Request  requests  a  Eurodollar  Borrowing,  such
Borrowing shall be made as an ABR Borrowing.

                  SECTION 2.16.  Increased Costs.  (a)  If any
Lender shall give notice to the Administrative Agent and
Level 3 at any time to the effect that Eurocurrency Reserve
Requirements are, or are scheduled to become, effective and
that such Lender is or will be generally subject to such
Eurocurrency Reserve Requirements as a result of which such
Lender will incur additional costs, then such Lender shall,
for each day from the later of the date of such notice and
the date on which such Eurocurrency Reserve Requirements
become effective, be entitled to additional interest on each
Eurodollar Loan made by it at a rate per annum determined
for such day (rounded upward to the nearest 100th of 1%)
equal to the remainder obtained by subtracting (i) the LIBO
Rate for such Eurodollar Loan from (ii) the rate obtained by
dividing such LIBO Rate by a percentage equal to 100% minus
the then-applicable Eurocurrency Reserve Requirements.  Such

additional interest will be payable in arrears to the Administrative  Agent, for
the account of such  Lender,  on each  Interest  Payment  Date  relating to such
Eurodollar  Loan and on any other  date when  interest  is  required  to be paid
hereunder  with respect to such Loan. Any Lender which gives a notice under this
paragraph  (a)  shall  promptly  withdraw  such  notice  (by  written  notice of
withdrawal  given  to  the  Administrative  Agent  and  Level  3) in  the  event
Eurocurrency  Reserve  Requirements  cease to  apply to it or the  circumstances
giving rise to such notice otherwise cease to exist.

                  (b)  If any Change in Law shall:

                  (i) impose,  modify or deem  applicable  any reserve,  special
         deposit or similar  requirement against assets of, deposits with or for
         the  account  of,  or  credit  extended  by,  any  Lender  (except  any
         Eurocurrency Reserve Requirement) or the Issuing Bank; or

                  (ii)  impose on any Lender or the  Issuing  Bank or the London
         interbank  market  any other  condition  affecting  this  Agreement  or
         Eurodollar  Loans  made by such  Lender  or any  Letter  of  Credit  or
         participation therein;

and the result of any of the  foregoing  shall be to  increase  the cost to such
Lender of making or  maintaining  any  Eurodollar  Loan (or of  maintaining  its
obligation  to make any such Loan) or to increase the cost to such Lender or the
Issuing Bank of participating in, issuing or maintaining any Letter of Credit or
to reduce the amount of any sum  received  or  receivable  by such Lender or the
Issuing Bank hereunder (whether of principal, interest or otherwise), then Level
3 and the Borrowers or the Incremental Borrower, as the case may be, will pay to
such Lender or the Issuing Bank, as the case may be, such  additional  amount or
amounts as will  compensate such Lender or the Issuing Bank, as the case may be,
for such additional costs incurred or reduction  suffered.  This Section 2.16(b)
shall not apply to any additional costs or reductions  relating to Taxes,  which
are governed by Section 2.18.

                  (c) If any  Lender or the  Issuing  Bank  determines  that any
Change in Law  regarding  capital  requirements  has or would have the effect of
reducing the rate of return on such Lender's or the Issuing Bank's capital or on
the capital of such Lender's or the Issuing Bank's holding company, if any, as a
consequence of this Agreement or the Loans made by, or participations in Letters
of Credit held by, such Lender,  or the Letters of Credit  issued by the Issuing
Bank, to a level

below that which such Lender or the Issuing Bank or such Lender's or the Issuing
Bank's  holding  company  could have achieved but for such Change in Law (taking
into consideration such Lender's or the Issuing Bank's policies and the policies
of such Lender's or the Issuing Bank's  holding  company with respect to capital
adequacy),  then from time to time Level 3 and the Borrowers or the  Incremental
Borrower,  as the case may be, will pay to such Lender such additional amount or
amounts as will  compensate  such Lender or the Issuing Bank or such Lender's or
the Issuing Bank's holding company for any such reduction suffered.

                  (d) A  certificate  of a Lender or the  Issuing  Bank  setting
forth the amount or amounts  necessary to compensate  such Lender or the Issuing
Bank or its holding  company,  as the case may be, as specified in paragraph (a)
or (b) of this Section  shall be  delivered  to Level 3 and shall be  conclusive
absent manifest error. Level 3 and the Borrowers or the Interim Borrower, as the
case may be shall pay such Lender or the Issuing  Bank,  as the case may be, the
amount  shown  as due on any  such  certificate  within  10 days  after  receipt
thereof.

                  (e)  Failure or delay on the part of any Lender or the Issuing
Bank to demand  compensation  pursuant to this  Section  shall not  constitute a
waiver of such Lender's or the Issuing Bank's right to demand such compensation;
provided  that Level 3 and the  Borrowers or the Interim  Borrower  shall not be
required to compensate a Lender or the Issuing Bank pursuant to this Section for
any increased costs or reductions  incurred more than 180 days prior to the date
that such Lender or the Issuing  Bank, as the case may be,  notifies  Level 3 of
the Change in Law giving rise to such increased  costs or reductions and of such
Lender's  or the  Issuing  Bank's  intention  to  claim  compensation  therefor;
provided  further that, if the Change in Law giving rise to such increased costs
or reductions is retroactive, then the 180-day period referred to above shall be
extended to include the period of retroactive effect thereof.

                  SECTION 2.17. Break Funding Payments.  In the event of (a) the
payment of any principal of any Eurodollar Loan other than on the last day of an
Interest Period applicable thereto (including as a result of an Event of Default
but excluding any payment of an Interim Loan in connection  with the making of a
simultaneous  Corresponding  Loan as  contemplated  by  Section  2.22),  (b) the
conversion  of any  Eurodollar  Loan other than on the last day of the  Interest
Period  applicable  thereto,  (c) the  failure to borrow,  convert,  continue or
prepay  any  Revolving  Loan or Term Loan on the date  specified  in any  notice
delivered

pursuant hereto  (regardless of whether such notice may be revoked under Section
2.11(g) and is revoked in accordance  therewith),  or (d) the  assignment of any
Eurodollar  Loan other than on the last day of the  Interest  Period  applicable
thereto as a result of a request by Level 3 pursuant to Section  2.19,  then, in
any such event,  Level 3 and the relevant Borrower or the Interim  Borrower,  as
applicable,  shall  compensate  each  Lender  for the  loss,  cost  and  expense
attributable to such event. In the case of a Eurodollar Loan, such loss, cost or
expense to any Lender shall be deemed not to include any lost profit  (including
loss of Applicable  Margin) and shall be deemed to include an amount  determined
by such  Lender to be the excess,  if any,  of (i) the amount of interest  which
would  have  accrued  on the  principal  amount of such Loan had such  event not
occurred,  at the LIBO Rate that is or would have been  applicable to such Loan,
for the period  from the date of such event to the last day of the then  current
Interest  Period  therefor  (or, in the case of a failure to borrow,  convert or
continue,  for the  period  that would  have been the  Interest  Period for such
Loan),  over (ii) the amount of interest  which would  accrue on such  principal
amount for such period at the interest  rate which such Lender would bid were it
to bid, at the commencement of such period,  for dollar deposits of a comparable
amount and period from other banks in the  eurodollar  market.  A certificate of
any Lender  setting  forth any amount or amounts that such Lender is entitled to
receive  pursuant to this  Section  shall be  delivered  to Level 3 and shall be
conclusive  absent  manifest  error.  Level 3 or the  relevant  Borrower  or the
Interim Borrower,  as applicable,  shall pay such Lender the amount shown as due
on any such certificate within 10 days after receipt thereof.

                  SECTION 2.18. Taxes. (a) Any and all payments by or on account
of any  obligation  of any Borrower  hereunder or under any other Loan  Document
shall be made free and clear of and without  deduction for any Indemnified Taxes
or Other Taxes;  provided  that if a Borrower or the Interim  Borrower  shall be
required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable  shall be  increased  as  necessary so that after making all
required deductions  (including deductions applicable to additional sums payable
under this  Section) the  Administrative  Agent,  Lender or Issuing Bank (as the
case may be) receives an amount  equal to the sum it would have  received had no
such deductions been made, (ii) such Borrower or the Interim Borrower shall make
such  deductions  and (iii) such Borrower or the Interim  Borrower shall pay the
full amount deducted to the relevant  Governmental  Authority in accordance with
applicable law.

                  (b) In addition,  each Borrower and the Interim Borrower shall
pay any Other Taxes to the relevant  Governmental  Authority in accordance  with
applicable law.

                  (c)  Level  3  and  the  relevant  Borrowers  or  the  Interim
Borrower,  as applicable,  shall indemnify the Administrative Agent, each Lender
and the Issuing Bank, within 10 days after written demand therefor, for the full
amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent,
such Lender or the Issuing  Bank,  as the case may be, on or with respect to any
payment by or on account  of any  obligation  of such  Borrower  or the  Interim
Borrower hereunder or under any other Loan Document (including Indemnified Taxes
or Other Taxes imposed or asserted on or  attributable  to amounts payable under
this  Section) and any  penalties,  interest  and  reasonable  expenses  arising
therefrom  or with respect  thereto,  whether or not such  Indemnified  Taxes or
Other  Taxes were  correctly  or legally  imposed or  asserted  by the  relevant
Governmental  Authority.  A  certificate  as to the  amount of such  payment  or
liability  delivered to Level 3 or the relevant Borrower or the Interim Borrower
by a Lender  or the  Issuing  Bank,  or by the  Administrative  Agent on its own
behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive  absent
manifest error.

                  (d) As soon as  practicable  after any payment of  Indemnified
Taxes or Other  Taxes by a Borrower or the  Interim  Borrower to a  Governmental
Authority,   such  Borrower  or  the  Interim  Borrower  shall  deliver  to  the
Administrative  Agent  reasonably  satisfactory  evidence of such payment or the
original or a certified copy of a receipt issued by such Governmental  Authority
evidencing  such  payment;  provided  however in no case shall such  Borrower be
required  to deliver  documentation  not  normally  issued by such  Governmental
Authority.

                  (e) Any Foreign  Lender that is entitled to an exemption  from
or reduction of withholding  tax under the law of the  jurisdiction in which the
Borrowers  or the  Interim  Borrower  are  located,  or any treaty to which such
jurisdiction  is a party,  with respect to payments under this  Agreement  shall
deliver  to Level 3 (with a copy to the  Administrative  Agent),  at the time or
times  prescribed  by  applicable  law,  such  properly  completed  and executed
documentation prescribed by applicable law or reasonably requested by Level 3 as
will permit such payments to be made without withholding or at a reduced rate.

                  SECTION 2.19. Payments Generally; Pro Rata
Treatment; Sharing of Set-offs.  (a) Each Borrower and the

                                                                              71

Interim  Borrower shall make each payment required to be made by it hereunder or
under  any  other  Loan  Document  (whether  of  principal,  interest,  fees  or
reimbursement  of LC  Disbursements,  or of amounts  payable under Section 2.16,
2.17 or 2.18, or otherwise)  prior to 1:00 p.m., New York City time, on the date
when due, in immediately  available funds, without set-off or counterclaim.  Any
amounts  received  after  such time on any date may,  in the  discretion  of the
Administrative  Agent,  be deemed to have been  received on the next  succeeding
Business Day for purposes of  calculating  interest  thereon.  All such payments
shall be made to the Administrative Agent at its offices at 270 Park Avenue, New
York,  New York,  except  payments to be made  directly  to the Issuing  Bank or
Swingline Lender as expressly  provided herein and except that payments pursuant
to  Sections  2.16,  2.17,  2.18 and 9.03 shall be made  directly to the Persons
entitled thereto and payments  pursuant to other Loan Documents shall be made to
the Persons specified  therein.  The  Administrative  Agent shall distribute any
such  payments  received  by it for  the  account  of any  other  Person  to the
appropriate  recipient promptly following receipt thereof.  If any payment under
any Loan Document shall be due on a day that is not a Business Day, the date for
payment shall be extended to the next succeeding  Business Day, and, in the case
of any payment  accruing  interest,  interest  thereon  shall be payable for the
period of such extension. All payments under each Loan Document shall be made in
dollars.

                  (b) If at any time  insufficient  funds  are  received  by and
available  to the  Administrative  Agent to pay fully all amounts of  principal,
unreimbursed LC Disbursements,  interest and fees then due hereunder, such funds
shall be applied (to the extent  determinable,  to the  Obligations  of the Loan
Party or Loan  Parties  providing  such  funds)  (i) first,  towards  payment of
interest and fees then due hereunder, ratably among the parties entitled thereto
in  accordance  with the amounts of interest and fees then due to such  parties,
and (ii) second,  towards payment of principal and unreimbursed LC Disbursements
then due  hereunder,  ratably among the parties  entitled  thereto in accordance
with the amounts of principal and unreimbursed LC Disbursements then due to such
parties.

                  (c) If any Lender shall, by exercising any right of set-off or
counterclaim  or  otherwise,  obtain  payment in respect of any  principal of or
interest on any of its Revolving  Loans,  Term Loans (other than Interim Loans),
Interim Loans or participations in LC Disbursements or Swingline Loans resulting
in such Lender receiving payment of a greater proportion of the aggregate amount
of its

                                                                              72

Revolving  Loans,  Term Loans  (other than  Interim  Loans),  Interim  Loans and
participations  in LC  Disbursements  and Swingline  Loans and accrued  interest
thereon  than the  proportion  received  by any other  Lender,  then the  Lender
receiving  such  greater  proportion  shall  purchase  (for cash at face  value)
participations  in the Revolving  Loans,  Term Loans (other than Interim Loans),
Interim Loans and  participations  in LC  Disbursements  and Swingline  Loans of
other  Lenders to the extent  necessary so that the benefit of all such payments
shall be shared by the Lenders ratably in accordance  with the aggregate  amount
of principal of and accrued interest on their respective  Revolving Loans,  Term
Loans  (other  than  Interim  Loans),  Interim  Loans and  participations  in LC
Disbursements and Swingline Loans;  provided that (i) if any such participations
are  purchased  and all or any  portion of the payment  giving  rise  thereto is
recovered,  such  participations  shall  be  rescinded  and the  purchase  price
restored  to the  extent  of such  recovery,  without  interest,  and  (ii)  the
provisions of this paragraph shall not be construed to apply to any payment made
by Level 3, any Borrower or the Interim  Borrower  pursuant to and in accordance
with the express terms of this Agreement or any payment  obtained by a Lender as
consideration  for the  assignment of or sale of a  participation  in any of its
Loans or  participations  in LC  Disbursements  to any assignee or  participant,
other than to Level 3 or any  Subsidiary  or Affiliate  thereof (as to which the
provisions  of this  paragraph  shall  apply).  Each  Borrower  and the  Interim
Borrower  consents to the foregoing and agrees, to the extent it may effectively
do so under  applicable  law, that any Lender  acquiring a  participation  in an
obligation  owed by it  pursuant  to the  foregoing  arrangements  may  exercise
against such Borrower or the Interim Borrower rights of set-off and counterclaim
with  respect to such  participation  as fully as if such  Lender  were a direct
creditor  of  such  Borrower  or the  Interim  Borrower  in the  amount  of such
participation.

                  (d) Unless the Administrative Agent shall have received notice
from  a  Borrower  prior  to  the  date  on  which  any  payment  is  due to the
Administrative  Agent  for  the  account  of the  Lenders  or the  Issuing  Bank
hereunder  that such  Borrower will not make such  payment,  the  Administrative
Agent may  assume  that such  Borrower  has made  such  payment  on such date in
accordance herewith and may, in reliance upon such assumption, distribute to the
Lenders or the Issuing  Bank, as the case may be, the amount due. In such event,
if such Borrower has not in fact made such payment,  then each of the Lenders or
the  Issuing  Bank,  as the  case  may be,  severally  agrees  to  repay  to the
Administrative  Agent  forthwith  on demand  the amount so  distributed  to such
Lender or Issuing Bank with interest thereon, for each day from and

including the date such amount is distributed to it to but excluding the date of
payment  to the  Administrative  Agent,  at the  greater  of the  Federal  Funds
Effective Rate and a rate determined by the  Administrative  Agent in accordance
with banking industry rules on interbank compensation.

                  (e) If any Lender  shall fail to make any payment  required to
be made by it pursuant to Section 2.04(c),  2.05(d) or (e), 2.06(b),  2.19(d) or
9.03(c),  then the Administrative Agent may, in its discretion  (notwithstanding
any contrary  provision hereof),  apply any amounts  thereafter  received by the
Administrative  Agent for the  account of such Lender to satisfy  such  Lender's
obligations under such Sections until all such unsatisfied obligations are fully
paid.

                  SECTION 2.20. Mitigation Obligations;  Replacement of Lenders.
(a) If any Lender requests  compensation  under Section 2.16, or if any Borrower
or the Interim  Borrower is required to pay any additional  amount to any Lender
or any Governmental  Authority for the account of any Lender pursuant to Section
2.18,  then such Lender  shall use  reasonable  efforts to designate a different
lending  office  for  funding or booking  its Loans  hereunder  or to assign its
rights  and  obligations  hereunder  to  another  of its  offices,  branches  or
affiliates,  if, in the judgment of such Lender,  such designation or assignment
(i) would eliminate or reduce amounts payable  pursuant to Section 2.16 or 2.18,
as the case may be, in the future and (ii) would not subject  such Lender to any
unreimbursed cost or expense and would not otherwise be  disadvantageous to such
Lender. Level 3 and the Borrowers or the Interim Borrower, as applicable, hereby
agree to pay all  reasonable  costs  and  expenses  incurred  by any  Lender  in
connection with any such designation or assignment.

                  (b) If any Lender  requests  compensation  under  Section 2.16
(other than  paragraph (a) of such  Section),  or if any Borrower or the Interim
Borrower  is  required  to  pay  any  additional  amount  to any  Lender  or any
Governmental  Authority for the account of any Lender  pursuant to Section 2.18,
if any Lender  defaults in its  obligation to fund Loans  hereunder or under the
circumstances  contemplated  by Section  9.02(c),  then Level 3 may, at its sole
expense and effort,  upon  notice to such Lender and the  Administrative  Agent,
require such Lender to assign and delegate, without recourse (in accordance with
and subject to the  restrictions  contained in Section 9.04), all its interests,
rights and  obligations  under this  Agreement to an assignee  that shall assume
such obligations (which assignee may be another Lender, if a Lender accepts such
assignment);

provided that (i) Level 3 shall have  received the prior written  consent of the
Administrative  Agent (and,  if a Revolving  Commitment is being  assigned,  the
Issuing Bank and Swingline  Lender),  which consent  shall not  unreasonably  be
withheld, (ii) such Lender shall have received payment of an amount equal to the
outstanding  principal of its Loans and  participations  in LC Disbursements and
Swingline Loans,  accrued interest  thereon,  accrued fees and all other amounts
payable to it  hereunder,  from the assignee (to the extent of such  outstanding
principal  and accrued  interest and fees) or Level 3, a Borrower or the Interim
Borrower, as applicable (in the case of all other amounts) and (iii) in the case
of any such  assignment  resulting from a claim for  compensation  under Section
2.16 or payments  required to be made pursuant to Section 2.18,  such assignment
will result in a reduction in such compensation or payments.  A Lender shall not
be required to make any such  assignment and delegation if, prior thereto,  as a
result of a waiver by such  Lender or  otherwise,  the  circumstances  entitling
Level 3 to require such assignment and delegation cease to apply.

                  SECTION 2.21.  Incremental Facility.  (a) At any time prior to
the Tranche B Maturity Date, Level 3 may, by notice to the Administrative  Agent
(which  shall  promptly  deliver  a copy to each of the  Lenders),  request  the
addition of a new tranche of Term Loans (all such Term Loans, collectively,  the
"Incremental  Loans")  provided,  however,  that  both at the  time of any  such
request and after  giving  effect to any such  Incremental  Loans (i) no Default
shall exist,  (ii) Level 3 and the  Borrowers  shall be in pro forma  compliance
with each financial covenant and (iii) if BTE is the Borrower of the Incremental
Loans,  the ratio of BTE Total Debt to BTE's Total Gross Assets,  on a pro forma
stand-alone  basis (after giving effect to the Incremental  Loans and the use of
Proceeds  thereof) shall not exceed .65 to 1.0. The Incremental  Loans (i) shall
be in an aggregate principal amount not in excess of $1,375,000,000, (ii) shall,
if BTE is the  Borrower of the  Incremental  Loans,  rank pari passu in right of
payment and of security with the Term Loans,  (iii) shall mature no sooner than,
and have a longer  average  weighted life than,  the Tranche B Term Loans,  (iv)
will  not   amortize   (other  than  nominal   amortization   customary  in  the
institutional  loan market) and will not mature  earlier than ten years from the
date hereof,  (v) shall not be available  unless the Tranche A  Commitments  and
Tranche B  Commitments  have been fully  utilized  and (vi) shall  otherwise  be
treated no more favorably than the Tranche B Term Loans  (including with respect
to mandatory  and  voluntary  prepayments);  provided  that (i) an amount not in
excess of $150,000,000 in principal  amount of the Incremental  Loans may mature
on the Tranche A Maturity Date

                                                                              75

(and amortize on a pro rata basis with the then remaining  Tranche A Loans prior
to such date),  (ii) an amount equal to not more than the excess of $625,000,000
over the amount of Incremental  Loans,  if any,  maturing as set forth in clause
(i) may mature on the Tranche B Maturity  Date (and amortize on a pro rata basis
with the then remaining Tranche B Loans prior to such date), and (iii) the terms
and conditions applicable to the Incremental Loans may provide for additional or
different financial or other covenants  applicable only during periods after the
Tranche B Maturity  Date.  Such notice shall set forth the  requested  amount of
Incremental  Loans  (which  amount  shall not  exceed  $1,375,000,000).  Level 3
currently  intends to offer each  existing  Lender  the  opportunity  to offer a
commitment to provide Incremental Loans;  provided,  however, no existing Lender
will be obligated to subscribe for any portion of such commitments. In the event
that existing  Lenders provide  commitments in an aggregate amount less than the
total  amount  of the  Incremental  Loans  requested  by Level 3,  Level 3 shall
arrange  for one or more  banks,  other  financial  institutions  or  vendors of
telecommunications  equipment  (any such bank,  other  financial  institution or
vendor being called an  "Additional  Lender") to extend  commitments  to provide
Incremental  Loans in an  aggregate  amount  equal to the  unsubscribed  amount,
provided that each Additional  Lender that is not a vendor of  telecommunication
equipment  shall be subject to the approval of the  Administrative  Agent (which
approval  shall  not  be  unreasonably  withheld).  Commitments  in  respect  of
Incremental Loans shall become  Commitments under this Agreement  pursuant to an
Incremental Facility Amendment to this Agreement and, as appropriate,  the other
Loan  Documents,  executed by each of the  Borrowers,  each  Lender  agreeing to
provide  such  Commitment,  if any,  each  Additional  Lender,  if any,  and the
Administrative  Agent.  The  Incremental  Facility  Amendment  may,  without the
consent of any other Lenders,  effect such  amendments to this Agreement and the
other Loan  Documents  (including,  if the  Incremental  Loans are  borrowed  by
Equipment Co. II as  contemplated  by clause (b) below,  execution of additional
ancillary  documents) as may be necessary or appropriate,  in the opinion of the
Administrative   Agent,   to  effect  the   provisions  of  this  Section.   The
effectiveness  of any  Incremental  Facility  Amendment  shall be subject to the
satisfaction  on the date thereof of each of the conditions set forth in Section
4.02.

                  (b) All or any portion of the  Incremental  Facilities  may be
borrowed,  at Level 3's option, by BTE or by a Wholly Owned newly formed special
purpose  equipment  Subsidiary  ("Equipment  Co. II").  In the latter case,  the
Incremental Facilities lenders to Equipment Co. II will be

secured only by the Telecommunications Assets financed in
whole or part with the proceeds of the Incremental Loans
made to Equipment Co. II.

                  SECTION  2.22.  Interim  Loans.  (a)  Subject to the terms and
conditions   set  forth   herein   (including   without   limitation   the  cash
collateralization  requirements set forth in paragraph (b) of this Section), the
Interim  Borrower  may (i)  effect  Borrowings  of  Tranche B Term  Loans on the
Effective  Date (such  Loans,  when  outstanding  as  Borrowings  by the Interim
Borrower,  being also  referred  to herein as  "Tranche B Interim  Loans")  from
Lenders  having  Tranche B  Commitments  in an  amount  not in excess of (x) the
amount of the Tranche B Commitments minus (y) the aggregate  principal amount of
Tranche B Term  Loans to be made to BTE on the  Effective  Date and (ii)  effect
Borrowings  on the  Effective  Date and from time to time  during the  Tranche A
Availability  Period and prior to the Tranche A Interim  Loan  Maturity  Date of
Tranche A Term Loans (such Loans,  when outstanding as Borrowings by the Interim
Borrower,  being  also  referred  to herein as  "Tranche A Interim  Loans"  and,
together  with the Tranche B Interim  Loans,  as "Interim  Loans")  from Lenders
having  Tranche A  Commitments  in an aggregate  principal  amount that will not
result in the  aggregate  principal  amount of the  Tranche A Term Loans then or
theretofore  made  (regardless  of  whether  repaid)  exceeding  the  Tranche  A
Commitments  then in effect.  Except to the extent  otherwise  provided  in this
Section 2.22 or elsewhere in Article II, the provisions of Article II (including
without  limitation  Sections  2.16,  2.17 and 2.18)  shall apply to the Interim
Loans and the Interim Borrower with the same effect as if each reference therein
to a Borrower were a reference to the Interim Borrower.

                  (b) On the Effective  Date, the Interim  Borrower will deposit
in an account with the  Administrative  Agent, in the name of the Administrative
Agent and for the  benefit of the  Tranche A Lenders  and the  Tranche B Lenders
(the "Interim Loan Collateral  Account"),  (i) all the proceeds of the Tranche B
Interim Loans plus (ii) an amount in cash equal to 4% of the principal amount of
the Tranche B Interim  Loans plus (iii) an amount in cash equal to the amount of
interest  that  would  accrue on the full  principal  amount  of such  Tranche B
Interim  Loans from the  Effective  Date to the Tranche B Interim Loan  Maturity
Date,  assuming no prepayments thereof and calculated on the basis of a constant
interest rate equal to the LIBO Rate for a Eurodollar Borrowing with an Interest
Period of two months  commencing on such borrowing date plus the Applicable Rate
for  Tranche B Term Loans on such  date.  On each date on which a  Borrowing  of
Tranche A Interim Loans occurs, the

<PAGE>


                                                                              77

Borrowers and the Interim  Borrower will deposit in the Interim Loan  Collateral
Account (i) all the proceeds of such Tranche A Interim Loans plus (ii) an amount
in cash equal to 1% of the principal amount of such Tranche A Interim Loans plus
(iii) an amount in cash equal to the amount of interest that would accrue on the
full  principal  amount of such  Tranche A Interim  Loans  from the date of such
Borrowing to the Tranche A Interim Loan Maturity  Date,  assuming no prepayments
thereof and  calculated  on the basis of a constant  interest  rate equal to the
LIBO Rate for a  Eurodollar  Borrowing  with an  Interest  Period of two  months
commencing on such borrowing  date plus the  Applicable  Rate for Tranche A Term
Loans on such date. Such deposits shall be held by the  Administrative  Agent as
collateral  for the payment of principal  of and interest on the Interim  Loans,
any prepayment  fees payable under Section 2.11 in respect of Interim Loans paid
or prepaid other than in connection  with a simultaneous  Corresponding  Loan to
BTE, as set forth below, and any amounts payable under Sections 2.12, 2.16, 2.17
or 2.18  attributable  to Interim Loans.  The Interim  Borrower  hereby grants a
security interest in the Interim Loan Collateral  Account for the benefit of the
Term Loan  Secured  Parties.  The  Administrative  Agent  shall  have  exclusive
dominion and control,  including the  exclusive  right of  withdrawal,  over the
Interim Loan Collateral Account.  The Administrative  Agent shall use reasonable
efforts, consistent with its standard administration procedures for similar cash
collateral  accounts,  to invest deposits in the Interim Loan Collateral Account
in readily marketable  Permitted  Investments  maturing in not more than 60 days
selected by the Interim  Borrower;  provided that (i) all such investments shall
be at the Interim  Borrower's risk and expense (and the Interim Borrower and the
Borrowers  agree that they will  promptly make  additional  cash deposits in the
Interim  Loan  Collateral  Account in the amount of any losses  realized on such
investments)  and (ii) the  Administrative  Agent  shall be  entitled to sell or
dispose  of  such  investments  at such  times  and in  such  amounts  as may be
necessary in the judgment of the  Administrative  Agent to provide funds for the
payment when due of obligations  secured by the Interim Loan Collateral Account.
Other than any interest  earned on the investment of such  deposits,  amounts in
the Interim  Loan  Collateral  Account  shall not bear  interest.  Interest  and
profits,  if any, on such  investments  shall  accumulate  in the  Interim  Loan
Collateral  Account.  Moneys in the Interim  Loan  Collateral  Account  shall be
applied  (and the  Administrative  Agent may from time to time sell or liquidate
investments in the Interim Loan  Collateral  Account to raise funds to apply) to
the payment when due of the  principal of and interest on the Interim  Loans and
the fees, indemnities and other amounts payable in

                                                                              78

respect of the Interim Loans referred to above.  Upon the payment in full of all
principal  of and interest on the Interim  Loans and all such fees,  indemnities
and other amounts,  any amounts remaining in the Interim Loan Collateral Account
shall be promptly returned to the Interim Borrower.

                  (c)  Notwithstanding  any other provision hereof, each Interim
Loan will at all  times be  maintained  as a  Eurodollar  Loan with an  Interest
Period of two-months;  provided, however, that on the Effective Date the Interim
Borrower  may  effect  Interim  Loans  which  are ABR  Loans so long as they are
converted to Eurodollar  Loans with an Interest Period of two-months  within two
Business Days of the Effective  Date. If and on each occasion  subsequent to two
Business  Days after the  Effective  Date that a  Projected  Interest  Shortfall
exists (whether due to increases in interest rates  applicable to Interim Loans,
payments  from or losses in the  Interim  Loan  Collateral  Account or any other
reason),  the Borrowers  and the Interim  Borrower will within two Business Days
deposit in the Interim Loan Collateral  Account such amounts as may be necessary
so that, after giving effect to such deposit,  no Projected  Interest  Shortfall
exists. For purposes hereof, a "Projected  Interest Shortfall" will be deemed to
exist on any date in the  amount  by which  (i) the sum of (x) the  accrued  and
unpaid  interest  on all  Interim  Loans  outstanding  on such date plus (y) the
aggregate amounts of interest that would accrue on each outstanding Interim Loan
from such date until the Tranche A Interim  Loan  Maturity  Date (in the case of
Tranche A Interim  Loans) or the Tranche B Interim  Loan  Maturity  Date (in the
case of Tranche B Interim  Loans),  assuming that the full  principal  amount of
each such Loan  remained  outstanding  until such maturity date and continued at
all times to bear  interest at the interest rate in effect for such Loan on such
date  exceeds  (ii) the  aggregate  amounts  then on deposit in the Interim Loan
Collateral  Account (with investments being valued at their fair market value on
such date, as reasonably  determined by the Administrative  Agent) minus the sum
of (x) 104% of the aggregate  outstanding  principal amount of Tranche B Interim
Loans on such date plus (y) 101% of the aggregate  outstanding  principal amount
of Tranche A Interim Loans on such date.

                  (d) At any  time  and  from  time to time on or  prior  to the
Tranche A Interim  Loan  Maturity  Date or the Tranche B Interim  Loan  Maturity
Date, respectively, BTE may, in accordance with the provisions of this paragraph
and subject to  satisfaction  of all  borrowing  conditions in Article IV hereof
(but regardless of whether the Tranche A Commitments

<PAGE>


                                                                              79

or the  Tranche  B  Commitments  have  expired  or  been  fully  drawn),  effect
borrowings of Tranche A Term Loans or Tranche B Term Loans, respectively,  which
will be funded out of the proceeds from the  simultaneous  payment or prepayment
by the Interim  Borrower of an equal principal amount of Tranche A Interim Loans
or Tranche B Interim Loans, as the case may be (any such Tranche A Term Loans or
Tranche  B Term  Loans to BTE so  funded  being  referred  to as  "Corresponding
Loans").  In order to effect a Borrowing by BTE of Corresponding  Loans, BTE and
the Interim  Borrower  shall,  not later than 1:00 p.m., New York City time, two
Business  Days  prior  to  the  date  of  the  proposed   Borrowing,   give  the
Administrative  Agent a Borrowing  Request complying (except as set forth below)
with the provisions of Section 2.03,  specifying that the requested Borrowing is
a Borrowing  of  Corresponding  Loans and  identifying  the Interim  Loans to be
repaid by the Interim Borrower to permit the funding of such Corresponding Loans
(which  Interim  Loans shall be in an aggregate  principal  amount equal to such
Corresponding Loans). Each Corresponding Loan in respect of an Interim Loan that
is a Eurodollar Loan being repaid other than on the last day of its then-current
Interest  Period shall have an initial  Interest Period ending on the same date,
and shall bear interest during such initial Interest Period at the same rate, as
the Interest  Period and interest rate  applicable to such Interim Loan,  and no
amounts  shall be payable  under  Section  2.17 in respect of the payment by the
Interim  Borrower of such  Interim  Loan prior to the last day of such  Interest
Period. Each Borrowing request for a Corresponding Loan shall be deemed to be an
irrevocable notice by the Interim Borrower of prepayment, on the applicable date
of Borrowing,  of the Interim Loans identified in such Borrowing Request. On the
date of the proposed Borrowing of Corresponding  Loans, the Administrative Agent
shall (i) apply funds from the Interim Loan Collateral Account to the payment in
full of the  principal  amount  of such  Interim  Loans  and,  on behalf of each
Tranche A Lender  or  Tranche B  Lender,  as the case may be,  entitled  to such
payment, utilize the proceeds thereof in accordance with Section 2.06(a) to fund
a Corresponding Loan to BTE in the same principal amount as the principal amount
of such  Lender's  Interim  Loan that was repaid  and (ii) apply  funds from the
Interim  Loan  Collateral  Account  to the  payment  of all  accrued  and unpaid
interest,  to the date of such repayment,  on the Interim Loans being repaid and
to the  payment  of any other  amounts  payable  under  Section  2.16 or 2.18 in
respect of such  Interim  Loans in respect of periods  prior to the date of such
repayment,  and  distribute  such payments to the Tranche A Lenders or Tranche B
Lenders  entitled  thereto.   The  Tranche  A  Lenders  and  Tranche  B  Lenders
irrevocably authorize the Administrative Agent to

<PAGE>


                                                                              80

fund Corresponding Loans with the proceeds of repayments of Interim Loans as set
forth above. From and after the date on which each  Corresponding  Loan is made,
such Loan shall for all purposes  hereof be a Tranche A Term Loan or a Tranche B
Term Loan, as the case may be, of BTE and shall cease to be an Interim Loan.

                  (e) Subject to the provisions of this  paragraph,  the Interim
Borrower may from time to time, by giving written notice (an "Extension Notice")
to the Administrative Agent prior to the then-current  maturity date, extend the
Tranche A Interim Loan Maturity Date or the Tranche B Interim Loan Maturity Date
to a Business Day specified in such  Extension  Notice that is not less than two
months after the then-current  Tranche A Interim Loan Maturity Date or Tranche B
Interim Loan  Maturity  Date,  as the case may be;  provided  that the Tranche A
Interim Loan  Maturity  Date may not be extended past the date that is 30 months
after the Effective Date and the Tranche B Interim Loan Maturity Date may not be
extended past the first  anniversary of the Effective Date. On each date that an
Extension  Notice is given to the  Administrative  Agent,  the Interim  Borrower
shall  deposit or cause to be deposited in the Interim Loan  Collateral  Account
such amounts as may be necessary  so that,  after giving  effect to such deposit
and to the extensions of one or both of the Tranche A Interim Loan Maturity Date
and the Tranche B Interim Loan Maturity Date specified in such Extension Notice,
no Projected  Interest  Shortfall exists on such date. An Extension Notice shall
be effective  only if such  deposit is made on the date on which such  Extension
Notice is given.  The  Administrative  Agent shall give the Tranche A Lenders or
the Tranche B Lenders, as the case may be, prompt notice of the effectiveness of
any  Extension  Notice  hereunder,  specifying  the new  Tranche A Interim  Loan
Maturity Date or Tranche B Interim Loan Maturity Date.

                  (f)  Notwithstanding  any  provision  to the  contrary in this
Agreement  or any other  Loan  Document,  (i) the  monetary  obligations  of the
Interim  Borrower  hereunder shall be limited to the payment of the principal of
and interest on the Interim  Loans and the payment of fees,  costs,  indemnities
and expense  reimbursements  (including without limitation  pursuant to Sections
2.12,  2.16, 2.17 and 2.18) directly  attributable to the Interim Loans and (ii)
the obligations of the Borrowers in respect of the monetary obligations referred
to in clause (i) shall be limited to their  obligations  to make deposits in the
Interim  Loan  Collateral  Account in  accordance  with the  provisions  of this
Section 2.22.

                                   ARTICLE III

                         Representations and Warranties

                  Each of  Level  3 and  each of the  Borrowers  represents  and
warrants to the Lenders that:

                  SECTION  3.01.  Organization;  Powers.  Each of  Level  3, the
Restricted  Subsidiaries  and the Interim  Borrower is duly  organized,  validly
existing  and in  good  standing  under  the  laws  of the  jurisdiction  of its
organization,  has all requisite power and authority to carry on its business as
now conducted  and,  except where the failure to do so,  individually  or in the
aggregate,  could not  reasonably  be expected  to result in a Material  Adverse
Effect,  is  qualified  to do business  in, and is in good  standing  in,  every
jurisdiction where such qualification is required.

                  SECTION 3.02.  Authorization; Enforceability.  The
                                 ------------------------------
Transactions to be entered into by each Loan Party and the Interim  Borrower are
within  such Loan  Party's or the Interim  Borrower's  powers and have been duly
authorized  by all  necessary  corporate  or  other  action  and,  if  required,
stockholder  or  member  action.  This  Agreement  has been  duly  executed  and
delivered  by  Level 3,  each of the  Borrowers  and the  Interim  Borrower  and
constitutes,  and each  other Loan  Document  to which any Loan Party is to be a
party, when executed and delivered by such Loan Party, will constitute, a legal,
valid and binding obligation of Level 3, such Borrowers, the Interim Borrower or
such Loan Party (as the case may be),  enforceable in accordance with its terms,
subject to  applicable  bankruptcy,  insolvency,  reorganization,  moratorium or
other  laws  affecting  creditors'  rights  generally  and  subject  to  general
principles of equity, regardless of whether considered in a proceeding in equity
or at law.

                  SECTION  3.03.  Governmental  Approvals;  No  Conflicts.   The
Transactions  (a) do not require any consent or  approval  of,  registration  or
filing with, or any other action by, any Governmental Authority,  except such as
have been obtained or made and are in full force and effect,  filings  necessary
to perfect Liens created under the Loan Documents and, in the case of Borrowings
by any Person other than the Interim Borrower,  the approvals listed on Schedule
3.03,  (b) will not violate any applicable law or regulation of a type typically
applicable to transactions of the type  contemplated by the  Transactions or the
charter, by-laws or other organizational documents of Level 3 or any

of the  Subsidiaries or any material order of any  Governmental  Authority,  (c)
will not violate or result in a default under any material indenture,  agreement
or other  instrument  binding  upon  Level 3 or any of the  Subsidiaries  or its
assets,  or give rise to a right thereunder to require any payment to be made by
Level 3 or any of the  Subsidiaries,  and (d) will not result in the creation or
imposition  of any  Lien  on  any  asset  of  Level  3 or any of the  Restricted
Subsidiaries  (or the Interim  Borrower),  except Liens  created  under the Loan
Documents.

                  SECTION 3.04. Financial Condition; No Material Adverse Change.
(a) Level 3 has heretofore furnished to the Lenders (i) its consolidated balance
sheet and statements of income, stockholders equity and cash flows as of and for
the fiscal year ended  December 31, 1998,  reported on by Arthur  Andersen  LLP,
independent  public  accountants,  and  (ii)  the  combined  balance  sheet  and
statements of income and cash flows of Level 3 and the  Restricted  Subsidiaries
as of and for the fiscal  quarter  and the portion of the fiscal year ended June
30, 1999,  certified by its chief financial officer.  Such financial  statements
present fairly, in all material respects,  the financial position and results of
operations and cash flows of Level 3 and its consolidated  Subsidiaries or Level
3 and its combined Restricted Subsidiaries, as the case may be, as of such dates
and for such  periods  in  accordance  with  GAAP,  subject  to  year-end  audit
adjustments and the absence of footnotes in the case of the statements  referred
to in clause (ii) above.

                  (b) Except as disclosed in the financial  statements  referred
to above or the notes thereto or in the  Information  Memorandum  and except for
the Disclosed Matters, after giving effect to the Transactions, none of Level 3,
the  Restricted  Subsidiaries  or the Interim  Borrower has, as of the Effective
Date, any material  contingent  liabilities,  unusual  long-term  commitments or
unrealized losses.

                  (c)  Since  December  31,  1998,  there  has been no  material
adverse change in the business,  assets,  operations or condition,  financial or
otherwise, of Level 3 and the Restricted Subsidiaries, taken as a whole.

                  SECTION  3.05.  Properties.  (a)  Each  of  Level  3  and  the
Restricted  Subsidiaries has good title to, or valid leasehold interests in, all
its real and personal property material to its business (including its Mortgaged
Properties),  except for minor defects in title that do not  interfere  with its
ability to conduct  its  business  as  currently  conducted  or to utilize  such
properties for their intended purposes.

                  (b) Each of Level 3 and the Restricted  Subsidiaries  owns, or
is licensed to use, all trademarks,  tradenames,  copyrights,  patents and other
intellectual  property material to its business,  and the use thereof by Level 3
and the  Restricted  Subsidiaries  to the knowledge of Level 3 does not infringe
upon the rights of any other  Person,  except for any such  infringements  that,
individually or in the aggregate,  could not reasonably be expected to result in
a Material Adverse Effect.

                  (c) Schedule 3.05 sets forth the address of each real property
that is owned or leased by Level 3 or any of the Restricted  Subsidiaries  as of
the Effective Date after giving effect to the Transactions.

                  (d) As of the Effective  Date,  neither Level 3 nor any of the
Restricted Subsidiaries has received notice of, or has knowledge of, any pending
or contemplated  condemnation proceeding affecting any Mortgaged Property or any
sale or  disposition  thereof in lieu of  condemnation.  Neither  any  Mortgaged
Property  nor any  interest  therein is  subject to any right of first  refusal,
option  or other  contractual  right to  purchase  such  Mortgaged  Property  or
interest therein.

                  SECTION 3.06. Litigation and Environmental  Matters. (a) There
are no actions, suits or proceedings by or before any arbitrator or Governmental
Authority  pending  against  or, to the  knowledge  of Level 3 or any  Borrower,
threatened  against or affecting  Level 3 or any of the Restricted  Subsidiaries
(i) as to which there is a reasonable  possibility  of an adverse  determination
and that, if adversely determined, could reasonably be expected, individually or
in the  aggregate,  to result  in a  Material  Adverse  Effect  (other  than the
Disclosed  Matters)  or (ii)  that  involve  any of the  Loan  Documents  or the
Transactions.

                  (b) Except for the  Disclosed  Matters and except with respect
to  any  other  matters  that,  individually  or in  the  aggregate,  could  not
reasonably be expected to result in a Material  Adverse Effect,  neither Level 3
nor any of the Subsidiaries (i) has failed to comply with any  Environmental Law
or to obtain,  maintain  or comply with any  permit,  license or other  approval
required  under  any   Environmental   Law,  (ii)  has  become  subject  to  any
Environmental Liability,  (iii) has received notice of any claim with respect to
any  Environmental  Liability  or (iv) knows of any basis for any  Environmental
Liability.

                  (c) Since the date of this Agreement, there has been no change
in the status of the Disclosed  Matters that,  individually or in the aggregate,
has resulted in, or materially  increased the likelihood of, a Material  Adverse
Effect.

                  SECTION 3.07.  Compliance  with Laws and  Agreements.  Each of
Level  3 and  the  Restricted  Subsidiaries  is in  compliance  with  all  laws,
regulations  and orders of any  Governmental  Authority  applicable to it or its
property and all indentures, agreements and other instruments binding upon it or
its  property,  except  where  the  failure  to do  so,  individually  or in the
aggregate,  could not  reasonably  be expected  to result in a Material  Adverse
Effect. No Default has occurred and is continuing.

                  SECTION 3.08.  Investment and Holding Company Status.  Neither
Level 3, any of the Loan Parties nor the Interim  Borrower is (a) an "investment
company"  or is  controlled  by an entity  that is an  "investment  company"  as
defined in, or subject to regulation  under, the Investment  Company Act of 1940
or (b) a "holding  company"  or is  controlled  by an entity  that is a "holding
company"  as defined  in, or subject to  regulation  under,  the Public  Utility
Holding Company Act of 1935.

                  SECTION 3.09.  Taxes. Each of Level 3 and the Subsidiaries has
timely filed or caused to be filed all tax returns and reports  required to have
been  filed and has paid or caused  to be paid all taxes  required  to have been
paid by it,  except  (a)  taxes  that  are  being  contested  in good  faith  by
appropriate proceedings and for which Level 3 or such Subsidiary, as applicable,
has set aside on its  books  adequate  reserves  or (b) to the  extent  that the
failure  to do so could not  reasonably  be  expected  to  result in a  Material
Adverse Effect.

                  SECTION  3.10.  ERISA.  No  ERISA  Event  has  occurred  or is
reasonably expected to occur that, when taken together with all other such ERISA
Events for which liability is reasonably  expected to occur, could reasonably be
expected  to result in a  Material  Adverse  Effect.  The  present  value of all
accumulated  benefit  obligations under each Plan (based on the assumptions used
for purposes of Statement of Financial  Accounting Standards No. 87) did not, as
of the date of the most recent  financial  statements  reflecting  such amounts,
exceed the fair market  value of the assets of such Plan by an amount that could
reasonably be expected to result in a Material  Adverse Effect,  and the present
value of all accumulated  benefit obligations of all underfunded Plans (based on
the assumptions used for purposes of

                                                                              85

Statement of Financial  Accounting  Standards No. 87) did not, as of the date of
the most recent financial  statements  reflecting such amounts,  exceed the fair
market value of the assets of all such underfunded Plans by an amount that could
reasonably be expected to result in a Material Adverse Effect.

                  SECTION 3.11. Disclosure. Level 3 has disclosed to the Lenders
all agreements, instruments and corporate or other restrictions to which Level 3
or any of the Restricted Subsidiaries is subject, and all other matters known to
any of  them,  that,  individually  or in the  aggregate,  could  reasonably  be
expected  to  result in a  Material  Adverse  Effect.  Neither  the  Information
Memorandum nor any of the other reports,  financial statements,  certificates or
other  information  furnished  by or on behalf of any Loan Party or the  Interim
Borrower  to the  Administrative  Agent or any  Lender  in  connection  with the
negotiation of this Agreement or any other Loan Document or delivered  hereunder
or thereunder (as modified or  supplemented  by other  information so furnished)
contains any material  misstatement  of fact or omits to state any material fact
necessary  to make the  statements  therein,  in the light of the  circumstances
under which they were made,  not  misleading;  provided  that,  with  respect to
projected financial  information,  Level 3 and the Borrowers represent only that
such information was prepared in good faith based upon  assumptions  believed to
be reasonable at the time.

                  SECTION 3.12. Subsidiaries.  Schedule 3.12 sets forth the name
of, and the ownership  interest of Level 3 in, each  Subsidiary  and  identifies
each  Subsidiary  that  is a  Subsidiary  Loan  Party,  in  each  case as of the
Effective Date.  Level 3 believes that the insurance  maintained by or on behalf
of Level 3 and the Restricted Subsidiaries is adequate.

                  SECTION   3.13.   Insurance.   Schedule   3.13  sets  forth  a
description  of all  insurance  maintained  by or on  behalf  of Level 3 and the
Restricted  Subsidiaries as of the Effective Date. As of the Effective Date, all
premiums in respect of such insurance have been paid to the extent due.

                  SECTION 3.14.  Labor Matters.  As of the Effective Date, there
are no material strikes, lockouts or slowdowns against Level 3 or any Restricted
Subsidiary pending or, to the knowledge of Level 3 or the Borrowers, threatened.
The  hours  worked  by and  payments  made  to  employees  of  Level  3 and  the
Subsidiaries  have not been in violation of the Fair Labor  Standards Act or any
other applicable Federal,  state, local or foreign law dealing with such matters
except where

                                                                              86

the  failure to do so could not  reasonably  be expected to result in a Material
Adverse Effect. All payments due from Level 3 or any Restricted  Subsidiary,  or
for which any claim may be made against Level 3 or any Restricted Subsidiary, on
account of wages and employee  health and welfare  insurance and other benefits,
have  been  paid or  accrued  as a  liability  on the  books  of Level 3 or such
Restricted  Subsidiary except where the failure to do so could not reasonably be
expected  to  result in a  Material  Adverse  Effect.  The  consummation  of the
Transactions  will  not  give  rise to any  right  of  termination  or  right of
renegotiation on the part of any union under any collective bargaining agreement
to which Level 3 or any Restricted Subsidiary is bound.

                  SECTION 3.15.  Intellectual Property.  Each of Level 3 and its
Restricted  Subsidiaries owns, or is licensed to use, all intellectual  property
that is necessary for the conduct of its business as currently  conducted except
for any failure to so own or license intellectual  property which,  individually
or in the aggregate, could not reasonably be expected to have a Material Adverse
Effect.  No claim has been  asserted to the  knowledge of Level 3 and is pending
against Level 3 or any Restricted Subsidiary  challenging or questioning the use
of any  intellectual  property  by it or the  validity or  effectiveness  of any
intellectual property used by it, except for any claims, which,  individually or
in the aggregate,  could not  reasonably be expected to have a Material  Adverse
Effect. The use of intellectual property by Level 3 or any Restricted Subsidiary
does not to the knowledge of Level 3 infringe on the rights of any person in any
material  respect and in any manner which could reasonably be expected to have a
Material Adverse Effect.

                  SECTION 3.16. Year 2000. Any reprogramming  required to permit
the proper  functioning,  in and  following  the year 2000,  of (a) the computer
systems of Level 3 and the Restricted  Subsidiaries and (b) equipment containing
embedded microchips  (including systems and equipment supplied by others or with
which  Level 3's  systems  interface)  and the  testing of all such  systems and
equipment,  as so  reprogrammed,  will be  completed by December 31, 1999 except
where the  failure  to do so could not  reasonably  be  expected  to result in a
Material Adverse Effect. The cost to Level 3 and the Restricted  Subsidiaries of
such reprogramming and testing and of the reasonably foreseeable consequences of
year 2000 to Level 3 and the Restricted  Subsidiaries  (including  reprogramming
errors and the  failure of others'  systems or  equipment)  will not result in a
Default  or a Material  Adverse  Effect.  Except  for such of the  reprogramming
referred to in the preceding sentence

                                                                              87

as may be necessary,  the computer and management information systems of Level 3
and the  Restricted  Subsidiaries  are and, with ordinary  course  upgrading and
maintenance,  will  continue to be,  sufficient to permit Level 3 to conduct its
businesses without a Material Adverse Effect.

                  SECTION  3.17.  Security  Interests.  (a)  When  executed  and
delivered, the Shared Collateral Pledge Agreement will be effective to create in
favor of the Agent for the  ratable  benefit  of the Shared  Collateral  Secured
Parties a valid and enforceable  security interest in the Collateral (as defined
in the Shared  Collateral  Pledge Agreement) and, when the portion of the Shared
Collateral  constituting  certificated  securities  (as  defined in the  Uniform
Commercial Code) is delivered to the  Administrative  Agent thereunder  together
with  instruments  of transfer  duly  endorsed in blank,  the Shared  Collateral
Pledge  Agreement shall constitute a fully perfected first priority Lien on, and
security interest in, all right,  title and interest of the pledgors  thereunder
in such Shared Collateral, prior and superior in right to any other Person.

                  (b) The Shared Collateral Security Agreement and the Term Loan
Security  Agreement  are each  effective to create in favor of the Agent for the
ratable  benefit  of the Shared  Collateral  Secured  Parties  and the Term Loan
Secured Parties,  respectively, a valid and enforceable security interest in the
Collateral  (as  defined  in  each  Security   Agreement)  and,  when  financing
statements  in  appropriate  form are  filed  in the  offices  specified  in the
Perfection  Certificate,  each  Security  Agreement  shall  constitute  a  fully
perfected  Lien on, and security  interest in, all right,  title and interest of
the grantors  thereunder in such  Collateral,  to the extent  perfection  can be
obtained by filing Uniform Commercial Code financing statements,  other than the
Intellectual  Property  (as  defined  in the  Security  Agreements),  in which a
security  interest  may be  perfected  by filing,  recording  or  registering  a
security  agreement,  financing  statement or  analogous  document in the United
States Patent and Trademark  Office or the United States  Copyright  Office,  as
applicable,  in each case prior and superior in right to any other Person to the
extent  perfection can be obtained by filing Uniform  Commercial  Code financing
statements,  other than with respect to the rights of Persons  pursuant to Liens
expressly permitted by Section 6.02.

                  (c) When each Security Agreement is filed in the United States
Patent and Trademark Office and the United States Copyright Office, the security
interest created thereunder shall constitute a fully perfected Lien on, and

                                                                              88

security  interest in, all right,  title and interest of the Loan Parties in the
Intellectual  Property  (as  defined  in such  Security  Agreement)  in  which a
security  interest  may be  perfected  by filing,  recording  or  registering  a
security  agreement,  financing  statement or  analogous  document in the United
States Patent and Trademark  Office or the United States  Copyright  Office,  as
applicable,  in each case prior and superior in right to any other Person, other
than with respect to the rights of Persons pursuant to Liens expressly permitted
by Section 6.02 (it being  understood that  subsequent  recordings in the United
States Patent and Trademark Office and the United States Copyright Office may be
necessary to perfect a lien on registered trademarks, trademark applications and
copyrights acquired by the Loan Parties after the date hereof).

                  (d) The  Mortgages  are  effective  to create,  subject to the
exceptions  listed in each title  insurance  policy  covering such Mortgage,  in
favor of the Agent for the  ratable  benefit  of the Shared  Collateral  Secured
Parties or Term Loan  Secured  Parties,  as the case may be, a legal,  valid and
enforceable Lien on all of the Loan Parties' right, title and interest in and to
the  Mortgaged  Properties  thereunder  and the proceeds  thereof,  and when the
Mortgages  are filed in the offices  specified on Schedule  3.18,  the Mortgages
shall  constitute  a Lien on, and  security  interest  in, all right,  title and
interest  of the Loan  Parties in such  Mortgaged  Properties  and the  proceeds
thereof,  in each case prior and  superior in right to any other  Person,  other
than with respect to Permitted Encumbrances.

                  SECTION 3.18.  Absence of Non-Permitted
Obligations.  None of the Equipment Borrowers or the Interim
Borrower has any obligations or liabilities other than as
permitted by Section 6.12.

                  SECTION 3.19. FCC Compliance.  (a) Level 3 and each Restricted
Subsidiary  are in  compliance  with the  Communications  Act  except  where the
failure  to do so could not  reasonably  be  expected  to  result in a  Material
Adverse Effect.

                  (b) To the  knowledge  of Level 3, there is no  investigation,
notice of apparent liability,  violation, forfeiture or other order or complaint
issued by or before the FCC, or of any other  proceedings  of or before the FCC,
affecting it or any Restricted  Subsidiary which could reasonably be expected to
have a Material Adverse Effect.

                  (c)  No event has occurred which (i) results in,
or after notice or lapse of time or both would result in,

revocation,   suspension,   adverse  modifications,   non-renewal,   impairment,
restriction  or  termination  of, or order of  forfeiture  with  respect to, any
License in any  respect  which could  reasonably  be expected to have a Material
Adverse Effect or (ii) affects or could  reasonably be expected in the future to
affect  any of the  rights  of Level 3 or any  Restricted  Subsidiary  under any
License held by Level 3 or such Subsidiary in any respect which could reasonably
be expected to have a Material Adverse Effect.

                  (d) Level 3 and each Restricted  Subsidiary have duly filed in
a  timely  manner  all  material  filings,  reports,  applications,   documents,
instruments and information  required to be filed by it under the Communications
Act,  and all such  filings  were when made true,  correct  and  complete in all
respects  except where the failure to do so could not  reasonably be expected to
result in a Material Adverse Effect.


                                   ARTICLE IV

                                   Conditions

         relating  to Level 3, the  Borrowers,  the Interim  Borrower,  the Loan

         of cash required to be deposited in the Interim Loan
         Collateral Account by Section 2.22.

The  Administrative  Agent shall notify Level 3 and the Lenders of the Effective
Date,  and such notice  shall be  conclusive  and binding.  Notwithstanding  the
foregoing,  the obligations of the Lenders to make Loans and of the Issuing Bank
to issue Letters of Credit  hereunder shall not become  effective unless each of
the foregoing conditions is satisfied (or waived pursuant to Section 9.02) at or
prior to 3:00 p.m.,  New York City time, on November 15, 1999 (and, in the event
such conditions are not so satisfied or waived,  the Commitments shall terminate

Equipment  Borrower.  The  obligations  of the  Lenders  to make Loans to the RC

                  (b) The  Administrative  Agent shall have received a favorable
         written opinion (addressed to the Administrative  Agent and the Lenders
         and  dated  the  Full  Effective  Date) of each of (i)  Willkie  Farr &

Effect.

                  SECTION  5.11.  Use of  Proceeds  and  Letters of Credit.  The

date of this  Agreement)  which  will be held and owned by BTE,  pledged  to the
Collateral  Agent for the  benefit  of the  Shared  Collateral  Secured  Parties
pursuant to the Shared Collateral  Security  Agreement or appropriate  Mortgages
and made  available  for use by  operating  Subsidiaries  pursuant to the Master
Lease  Agreement.  The  proceeds  of the  Incremental  Loans,  if  borrowed by a
Subsidiary of Level 3 other than BTE, shall be used by such Subsidiary solely to

corporate  purposes,  including  the  construction,  expansion,  development  or
acquisition  of  Telecommunications   Assets  and   Telecommunications   Related
Businesses.  The  proceeds  of the  Interim  Loans  shall be used solely to make

longer period, not to exceed 30 days, as the Administrative Agent may agree to),

such  Subsidiary  (if it is a  Subsidiary  Loan  Party) and with  respect to any
Equity Interest in or  Indebtedness of such Subsidiary  owned by or on behalf of
any Loan Party.

                  SECTION 5.13. Further  Assurances.  (a) Level 3 will, and will

all further documents,  financing  statements,  agreements and instruments,  and
take all such further  actions  (including the filing and recording of financing
statements,  fixture filings,  mortgages,  deeds of trust and other  documents),

Agent  or the  Required  Lenders  may  reasonably  request,  to  effectuate  the
transactions  contemplated by the Loan Documents or to grant, preserve,  protect
or perfect the Liens created or intended to be created by the Loan  Documents or
the  validity  or  priority  of any such  Lien,  all at the  expense of the Loan
Parties or the Interim Borrower,  as the case may be. Level 3, the Borrowers and
the Interim  Borrower also agree to provide to the  Administrative  Agent,  from
time  to  time  upon   request,   evidence   reasonably   satisfactory   to  the
Administrative  Agent as to the  perfection and priority of the Liens created or
intended to be created by the Loan Documents.

                  (b) If any material  assets  (including  any real  property or
improvements  thereto or any  interest  therein)  are acquired by Level 3 or any
Subsidiary   Loan  Party  after  the  Effective  Date  (other  than  (i)  assets
constituting Collateral under the Security Agreements that become subject to the
Lien of the  applicable  Security  Agreements  upon  acquisition  thereof,  (ii)
Specified  Real Estate or any parcel of real  estate  which,  together  with any
structures thereon and existing improvements thereto, has a fair market value at
the time of  acquisition  thereof not in excess of  $7,000,000  or (iii)  assets
subject to Liens  securing  Indebtedness  permitted by Sections  6.01 and 6.02),
Level 3 will notify the Administrative  Agent and the Lenders thereof, and Level
3 will  cause  such  assets  to be  subjected  to a  Lien  securing  the  Shared
Collateral  Secured  Obligations  and will take, and cause the  Subsidiary  Loan
Parties to take,  such actions as shall be necessary or reasonably  requested by
the  Administrative  Agent to grant and perfect  such Liens,  including  actions
described  in  paragraph  (a) of this  Section,  all at the  expense of the Loan
Parties.

                  (c) If any Telecom Equipment Assets are acquired by Whitney or
any of its subsidiaries after the Effective Date (other than assets constituting
Collateral under the Security  Agreements that become subject to the Lien of the
applicable Security Agreement upon acquisition  thereof) Level 3 will notify the
Administrative Agent and the Lenders thereof and cause such assets to be subject
to a Lien securing the Shared Collateral Secured  Obligations and will take, and
cause Whitney and its subsidiaries to take, such

actions as shall be necessary  or  reasonably  requested  by the  Administrative
Agent to grant and perfect such Liens,  including actions described in paragraph
(a) of this Section, all at the expense of Whitney or the Loan Parties.

the Effective  Date,  Level 3 will enter into, and  thereafter  will maintain in
effect,  one or more  interest  rate  protection  agreements  with  Lenders  (or
Affiliates thereof) or such other parties as shall be reasonably satisfactory to
the  Administrative  Agent,  the effect of which (when taken together with other
fixed rate  indebtedness)  shall be to fix or limit the interest cost to Level 3
with respect to at least 30% of the  outstanding  Combined Total Debt of Level 3
and the Restricted Subsidiaries (including fixed rate indebtedness).

                  SECTION  5.15.  Support of Equipment  Borrowers.  Level 3 will

required to be paid in respect  thereof  exceeds such Equipment  Borrower's then
available cash.

         Telecommunications  Assets  that are  fixtures  thereto) at the time of
         incurrence of such Indebtedness (as reasonably  determined by the chief
         financial officer of Level 3);

be  accelerated,  payable or subject to repurchase  prior to its final scheduled
maturity)   upon  the  occurrence  of  a  default  with  respect  to  any  other
Indebtedness that is Indebtedness of an Unrestricted  Subsidiary,  except in the
case of clause (x) or (y) to the extent permitted under Section 6.01 and Section
6.05  hereof.  Each  Designation  shall  be  irrevocable,  and  no  Unrestricted
Subsidiary may become a Restricted Subsidiary, be merged with or into Level 3 or
a Restricted  Subsidiary  or liquidate  into or transfer  substantially  all its
assets to Level 3 or a Restricted Subsidiary.

         (i) as a  result  of the sale or other  disposition  of the  applicable
         Collateral in a transaction  permitted under the Loan Documents or (ii)
         as a result of the Agent's failure to maintain  possession of any stock

times:  (i) terminate the  Commitments,  and  thereupon  the  Commitments  shall
terminate immediately, and (ii) declare the Loans then outstanding to be due and
payable in whole (or in part,  in which case any principal not so declared to be
due and payable may thereafter be declared to be due and payable), and thereupon
the  principal  of the Loans so declared to be due and  payable,  together  with
accrued interest thereon and all fees and other obligations of the Borrowers and
the  Interim   Borrower  accrued   hereunder,   shall  become  due  and  payable

together with accrued interest thereon and all fees and other obligations of the
Borrowers and the Interim Borrower accrued hereunder, shall automatically become

kind, all of which are hereby waived by the Borrowers and the Interim  Borrower;
provided,  however, that notwithstanding the foregoing, in the case of any Event
of Default that relates solely to the Interim  Borrower,  payment or performance
of the obligations of the Interim Borrower  hereunder,  the Interim Loans or the
security  interests in and Liens on the deposits and  investments in the Interim
Loan  Collateral  Account,  the  remedies  of the  Administrative  Agent and the
Required  Lenders  under this Article  shall be limited to (i)  terminating  the
Commitments  to make Interim  Loans and (ii)  declaring  the Interim  Loans then
outstanding to be due and payable, in each case as and with the effect set forth

                                    The Agent

                  Each of the Lenders and the  Issuing  Bank hereby  irrevocably
appoints the Agent as its agent and authorizes the Agent to take such actions on
its behalf and to  exercise  such  powers as are  delegated  to the Agent by the
terms of

                                                                             126

the Loan  Documents,  together  with such  actions and powers as are  reasonably
incidental thereto.

                  The bank  serving as the Agent  hereunder  shall have the same
rights  and  powers in its  capacity  as a Lender as any  other  Lender  and may
exercise  the same as  though  it were  not the  Agent,  and  such  bank and its
Affiliates may accept deposits from,  lend money to and generally  engage in any
kind of business with Level 3, the Borrower or any Subsidiary or other Affiliate
thereof as if it were not the Agent hereunder.

                  It is  understood  that no  Syndication  Agent  shall have any
duties or  obligations  under this  Agreement  (other than in its  capacity as a
Lender).  The  Agent  shall  not have any  duties or  obligations  except  those
expressly set forth in the Loan  Documents.  Without  limiting the generality of
the  foregoing,  (a) the Agent  shall not be subject to any  fiduciary  or other
implied duties,  regardless of whether a Default has occurred and is continuing,
(b) the  Agent  shall  not have any duty to take  any  discretionary  action  or
exercise  any  discretionary  powers,  except  discretionary  rights  and powers
expressly  contemplated  by the Loan  Documents  that the Agent is  required  to
exercise in writing by the Required  Lenders (or such other number or percentage
of the  Lenders as shall be  necessary  under the  circumstances  as provided in
Section 9.02), and (c) except as expressly set forth in the Loan Documents,  the
Agent  shall not have any duty to  disclose,  and  shall  not be liable  for the
failure to disclose,  any information  relating to Level 3, the Borrowers or any
of the  Subsidiaries  that is communicated to or obtained by the bank serving as
Agent or any of its  Affiliates in any  capacity.  The Agent shall not be liable
for any action  taken or not taken by it with the  consent or at the  request of
the Required Lenders (or such other number or percentage of the Lenders as shall
be  necessary  under the  circumstances  as provided in Section  9.02) or in the
absence of its own gross negligence or wilful misconduct. The Agent shall not be
deemed not to have  knowledge  of any Default  unless and until  written  notice
thereof is given to the Agent by Level 3, a Borrower or a Lender,  and the Agent
shall not be  responsible  for or have any duty to ascertain or inquire into (i)
any statement, warranty or representation made in or in connection with any Loan
Document,  (ii) the  contents  of any  certificate,  report  or  other  document
delivered  thereunder  or in  connection  therewith,  (iii) the  performance  or
observance of any of the covenants,  agreements or other terms or conditions set
forth in any Loan Document, (iv) the validity, enforceability,  effectiveness or
genuineness of any Loan Document or any other agreement, instrument or

document,  or (v) the  satisfaction  of any condition set forth in Article IV or
elsewhere in any Loan Document, other than to confirm receipt of items expressly
required to be delivered to the Agent.

                  The Agent shall be entitled to rely upon,  and shall not incur
any liability  for relying  upon,  any notice,  request,  certificate,  consent,
statement,  instrument,  document or other writing  believed by it to be genuine
and to have been  signed or sent by the proper  Person.  The Agent also may rely
upon any  statement  made to it orally or by telephone  and believed by it to be
made by the  proper  Person,  and  shall not incur  any  liability  for  relying
thereon.  The Agent may consult with legal counsel (who may be counsel for Level
3 or the Borrowers),  independent  accountants and other experts selected by it,
and shall not be liable  for any action  taken or not taken by it in  accordance
with the advice of any such counsel, accountants or experts.

                  The Agent may perform any and all its duties and  exercise its
rights and  powers by or through  any one or more  sub-agents  appointed  by the
Agent.  The Agent and any such  sub-agent may perform any and all its duties and
exercise its rights and powers through their  respective  Related  Parties.  The
exculpatory  provisions  of the  preceding  paragraphs  shall  apply to any such
sub-agent and to the Related Parties of each Agent and any such  sub-agent,  and
shall apply to their respective activities in connection with the syndication of
the credit facilities provided for herein as well as activities as Agent.

                  Subject to the  appointment  and acceptance of a successor the
Agent as  provided  in this  paragraph,  the  Agent  may  resign  at any time by
notifying the Lenders,  the Issuing Bank and Level 3. Upon any such resignation,
the Required Lenders shall have the right,  with, so long as no Default or Event
of Default shall have occurred and be continuing,  the consent of Level 3 (which
consent shall not be  unreasonably  withheld or delayed) to appoint a successor.
If no successor  shall have been so appointed by the Required  Lenders and shall
have accepted  such  appointment  within 30 days after the retiring  Agent gives
notice of its resignation, then the retiring Agent may, on behalf of the Lenders
and the Issuing  Bank,  appoint a successor  Agent which shall be a bank with an
office in New  York,  New  York,  or an  Affiliate  of any such  bank.  Upon the
acceptance of its appointment as Agent hereunder by a successor,  such successor
shall succeed to and become vested with all the rights,  powers,  privileges and
duties of the retiring  Agent,  and the retiring Agent shall be discharged  from
its duties

                                                                             128

and  obligations  hereunder.  The fees payable by Level 3 and the Borrowers to a
successor  Agent shall be the same as those  payable to its  predecessor  unless
otherwise agreed with such successor.  After the Agent's resignation  hereunder,
the provisions of this Article and Section 9.03 shall continue in effect for the
benefit of such retiring  Agent,  its  sub-agents and their  respective  Related
Parties in respect  of any  actions  taken or omitted to be taken by any of them
while it was acting as Agent.

                  Each  Lender  acknowledges  that  it  has,  independently  and
without  reliance upon the Agent or any other Lender and based on such documents
and information as it has deemed  appropriate,  made its own credit analysis and
decision to enter into this  Agreement.  Each Lender also  acknowledges  that it
will,  independently and without reliance upon the Agent or any other Lender and
based on such  documents  and  information  as it shall  from  time to time deem
appropriate,  continue to make its own  decisions in taking or not taking action
under or based upon this Agreement, any other Loan Document or related agreement
or any document furnished hereunder or thereunder.

                  SECTION 9.02. Waivers;  Amendments. (a) No failure or delay by
the Administrative Agent, the Issuing Bank or any Lender in exercising any right
or power  hereunder or under any other Loan  Document  shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right or power, or
any  abandonment  or  discontinuance  of steps to enforce such a right or power,
preclude  any other or further  exercise  thereof or the  exercise  of any other
right or power. The rights and remedies of the Administrative Agent, the Issuing
Bank and the Lenders hereunder and under the other Loan Documents are cumulative
and are not exclusive of any rights or remedies that they would  otherwise have.
No waiver of any  provision of any Loan  Document or consent to any departure by
any Loan Party therefrom  shall in any event be effective  unless the same shall
be permitted by paragraph (b) of this  Section,  and then such waiver or consent
shall be effective  only in the specific  instance and for the purpose for which
given. Without limiting the generality of the foregoing, the making of a Loan or
issuance  of a Letter  of  Credit  shall  not be  construed  as a waiver  of any
Default,  regardless  of whether  the  Administrative  Agent,  any Lender or the
Issuing Bank may have had notice or knowledge of such Default at the time.

                  (b) Neither this Agreement nor any other Loan Document nor any
provision hereof or thereof may be waived,

amended  or  modified  except,  in the case of this  Agreement,  pursuant  to an
agreement or  agreements  in writing  entered into by Level 3, the Borrowers and
the Required Lenders or, in the case of any other Loan Document,  pursuant to an
agreement or agreements in writing entered into by the Administrative  Agent and

Lender,  (ii)  reduce the  principal  amount of any Loan or LC  Disbursement  or
reduce  the rate of  interest  thereon,  or reduce any fees  payable  hereunder,

consent of each Lender,  (v) change any of the provisions of this Section or the

determination  or grant any consent  thereunder,  without the written consent of
each  Lender (or each Lender of such Class,  as the case may be),  (vi)  release
Level 3 or any  other  Guarantor  from  its  Guarantee  under  either  Guarantee
Agreement (except as expressly provided in such Guarantee  Agreement),  or limit
its liability in respect of any such  Guarantee,  without the written consent of
each Lender,  (vii) release all or any  substantial  part of the Collateral from
the Liens of the Security  Documents  other than in connection  with any sale of

the  outstanding  Loans and unused  Commitments  of each affected  Class or (ix)
change the rights of the Tranche B Lenders to decline  mandatory  prepayments as
provided  in Section  2.11,  without  the  written  consent of Tranche B Lenders
holding a majority of the outstanding Tranche B Loans; provided further that (A)
no such agreement shall amend,  modify or otherwise  affect the rights or duties
of the  Administrative  Agent,  the Issuing Bank or the Swingline Lender without
the prior written consent of the

Administrative  Agent, the Issuing Bank or the Swingline Lender, as the case may
be, (B) any waiver,  amendment or  modification  of this  Agreement  that by its
terms affects the rights or duties under this Agreement of the Revolving Lenders
(but not the Tranche A Lenders  and  Tranche B  Lenders),  the Tranche A Lenders
(but not the  Revolving  Lenders and Tranche B Lenders) or the Tranche B Lenders
(but not the  Revolving  Lenders  and  Tranche A Lenders)  may be effected by an
agreement or  agreements  in writing  entered into by Level 3, the Borrowers and
requisite  percentage  in interest of the affected  Class of Lenders and (C) for
the avoidance of doubt,  the Loan Allocation  Agreement may be waived or amended
only in accordance with the terms thereof.

                  (c) If,  in  connection  with  any  proposed  change,  waiver,
discharge  or  termination  of  any of  the  provisions  of  this  Agreement  as
contemplated  by clauses (i) through (vii),  inclusive,  of the first proviso to
Section 9.02(b), the consent of the Required Lenders is obtained but the consent
of one or more of such other  Lenders  whose  consent is sought is not obtained,
then the Borrowers shall have the right, so long as all  non-consenting  Lenders
whose  individual  consent is sought are treated as described in either  clauses
(A) or (B)  below,  to either (A)  replace  each such  non-consenting  Lender or
Lenders with one or more  replacement  Lenders in accordance with the provisions
of  Section  2.20(b)  so long as at the  time of  such  replacement,  each  such
replacement  Lender  consents  to the  proposed  change,  waiver,  discharge  or
termination or (B) terminate each such non-consenting  Lender's  Commitments and
repay the  outstanding  Loans of each such  non-consenting  Lender in accordance
with Sections 2.08 and 2.11,  provided  that,  unless the  Commitments  that are
terminated  and the Loans that are repaid  pursuant to preceding  clause (B) are
immediately replaced in full at such time through the addition of new Lenders or
the increase of the Commitments  and/or  outstanding  Loans of existing  Lenders
(who in each case must specifically  consent  thereto),  then in the case of any
action  pursuant to preceding  clause (B) each Lender  (determined  after giving
effect to the proposed  action) shall  specifically  consent  thereto,  provided
further,  that in any event the  Borrower  shall not have the right to replace a
Lender,  terminate its  Commitments or repay its Loans solely as a result of the
exercise of such Lender's rights (and the withholding of any required consent by
such Lender)  pursuant to clauses (viii) or (ix) of the first proviso of Section
9.02(b) or any clause of the second proviso to Section 9.02(b).

                  SECTION 9.03.  Expenses; Indemnity; Damage Waiver.
(a)  Level 3 and the Borrowers shall pay, on a joint and
several basis, (i) all reasonable out-of-pocket expenses

incurred  by  the  Administrative  Agent  and  its  Affiliates,   including  the
reasonable fees,  charges and  disbursements  of counsel for the  Administrative
Agent, in connection with the syndication of the credit facilities  provided for
herein,  the  preparation  and  administration  of  the  Loan  Documents  or any
amendments,  modifications or waivers of the provisions  thereof (whether or not
the transactions contemplated hereby or thereby shall be consummated),  (ii) all
reasonable  out-of-pocket  expenses  incurred by the Issuing Bank in  connection
with the  issuance,  amendment,  renewal or extension of any Letter of Credit or
any demand for payment thereunder and (iii) all out-of-pocket  expenses incurred
by the Administrative Agent, the Issuing Bank or any Lender, including the fees,
charges and  disbursements  of not more than three separate  outside counsel (as
well as separate local and regulatory counsel) for the Administrative Agent, the
Issuing Bank and the Lenders,  in connection  with the enforcement or protection
of its rights in connection with the Loan Documents,  including its rights under
this Section,  or in connection  with the Loans made or Letters of Credit issued
hereunder,  including  all  such  out-of-pocket  expenses  incurred  during  any
workout,  restructuring  or  negotiations in respect of such Loans or Letters of
Credit.

                  (b) Level 3 and the Borrowers shall indemnify,  on a joint and
several basis, the  Administrative  Agent, the Issuing Bank and each Lender, and
each  Related  Party of any of the  foregoing  Persons  (each such Person  being
called an "Indemnitee") against, and hold each Indemnitee harmless from, any and
all losses,  claims,  damages,  liabilities and related expenses,  including the
fees,  charges and disbursements of any counsel for any Indemnitee,  incurred by
or asserted  against any Indemnitee  arising out of, in connection with, or as a
result  of (i) the  execution  or  delivery  of any Loan  Document  or any other
agreement or instrument  contemplated  hereby, the performance by the parties to
the  Loan  Documents  of  their   respective   obligations   thereunder  or  the
consummation of the Transactions or any other transactions  contemplated hereby,
(ii)  any  Loan  or  Letter  of  Credit  or the  use of the  proceeds  therefrom
(including any refusal by the Issuing Bank to honor a demand for payment under a
Letter of Credit if the documents  presented in  connection  with such demand do
not strictly  comply with the terms of such Letter of Credit),  (iii) any actual
or alleged  presence or release of Hazardous  Materials on or from any Mortgaged
Property or any other  property  owned or operated by the Borrower or any of the
Subsidiaries,  or any Environmental Liability related in any way to the Borrower
or any of the Subsidiaries, or (iv) any actual or prospective claim, litigation,
investigation or proceeding relating to any of the foregoing, whether based

on contract,  tort or any other theory and  regardless of whether any Indemnitee
is a  party  thereto;  provided  that  such  indemnity  shall  not,  as  to  any
Indemnitee,  be  available  to the extent  that such  losses,  claims,  damages,
liabilities  or  related  expenses  are  determined  by  a  court  of  competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or wilful misconduct of such Indemnitee.

                  (c) To the extent that Level 3 and the  Borrowers  fail to pay
any amount required to be paid by them to the Administrative  Agent, the Issuing
Bank or the Swingline  Lender under  paragraph (a) or (b) of this Section,  each
Lender severally agrees to pay to the Administrative  Agent, the Issuing Bank or
the  Swingline  Lender,  as the  case  may be,  such  Lender's  pro  rata  share
(determined as of the time that the applicable unreimbursed expense or indemnity
payment is sought) of such unpaid amount; provided that the unreimbursed expense
or indemnified loss, claim,  damage,  liability or related expense,  as the case
may be, was  incurred  by or  asserted  against the  Administrative  Agent,  the
Issuing  Bank or the  Swingline  Lender in its  capacity as such.  For  purposes
hereof,  a Lender's "pro rata share" shall be determined based upon its share of
the sum of the total  Revolving  Exposures,  outstanding  Term  Loans and unused
Commitments at the time.

                  (d) To the extent permitted by applicable law, neither Level 3
nor any Borrower  shall assert,  and each hereby  waives,  any claim against any
Indemnitee, on any theory of liability, for special, indirect,  consequential or
punitive  damages  (as opposed to direct or actual  damages)  arising out of, in
connection  with,  or as a  result  of,  this  Agreement  or  any  agreement  or
instrument  contemplated hereby, the Transactions,  any Loan or Letter of Credit
or the use of the proceeds thereof.

                  (e) All  amounts  due  under  this  Section  shall be  payable
promptly after written demand therefor.

                  SECTION 9.04.  Successors and Assigns.  (a)  The
                                 -----------------------
provisions of this  Agreement  shall be binding upon and inure to the benefit of
the parties hereto and their respective  successors and assigns permitted hereby
(including  any Affiliate of the Issuing Bank that issues any Letter of Credit),
except that the Borrower may not assign or otherwise  transfer any of its rights
or obligations  hereunder  without the prior written consent of each Lender (and
any attempted  assignment or transfer by the Borrower without such consent shall
be null and void).  Nothing in this  Agreement,  expressed or implied,  shall be
construed to

confer  upon  any  Person  (other  than the  parties  hereto,  their  respective
successors and assigns  permitted hereby (including any Affiliate of the Issuing
Bank that issues any Letter of Credit) and, to the extent expressly contemplated
hereby,  the Related Parties of each of the  Administrative  Agent,  the Issuing
Bank and the Lenders) any legal or equitable right,  remedy or claim under or by
reason of this Agreement.

                  (b) Any Lender may  assign to one or more  assignees  all or a
portion of its rights and obligations  under this Agreement  (including all or a
portion of its Commitment and the Loans at the time owing to it);  provided that
(i) except in the case of an  assignment to a Lender or an Affiliate of a Lender
or a  Related  Fund  of a  Lender,  each  of the  applicable  Borrowers  and the
Administrative Agent (and, in the case of an assignment of all or a portion of a
Revolving  Commitment or any Lender's  obligations in respect of its LC Exposure
or  Swingline  Exposure,  the Issuing Bank and the  Swingline  Lender) must give
their prior  written  consent to such  assignment  (which  consent  shall not be
unreasonably withheld or delayed), (ii) except in the case of an assignment to a
Lender  or an  Affiliate  of a  Lender  or a  Related  Fund  of a  Lender  or an
assignment of the entire remaining amount of the assigning  Lender's  Commitment
or Loans,  the amount of the Commitment or Loans of the assigning Lender subject
to each such assignment (determined as of the date the Assignment and Acceptance
with respect to such assignment is delivered to the Administrative  Agent) shall
not be less than  $5,000,000  unless  each of the  applicable  Borrower  and the
Administrative  Agent otherwise consent,  (iii) each partial assignment shall be
made as an assignment  of a  proportionate  part of all the  assigning  Lender's
rights and obligations under this Agreement, except that this clause (iii) shall
not be construed to prohibit the assignment of a  proportionate  part of all the
assigning Lender's rights and obligations in respect of one Class of Commitments
or Loans,  (iv) the parties to each assignment  shall execute and deliver to the
Administrative  Agent an Assignment and  Acceptance,  together with a processing
and  recordation  fee of  $3,500,  and (v) the  assignee,  if it shall  not be a
Lender,   shall   deliver  to  the   Administrative   Agent  an   Administrative
Questionnaire;  and provided further that any consent of the Borrowers otherwise
required under this paragraph shall not be required if an Event of Default under
clauses (a), (b), (h) or (i) of Article VII has occurred and is  continuing  and
any assignment made pursuant to the Loan Allocation  Agreement shall not require
any  consent  of any party  hereunder,  shall not  require  the  payment  of any
processing  and  recordation  fee, and shall be effected in accordance  with the
provisions of the Loan Allocation

                                                                             135

Agreement,  notwithstanding  any inconsistency  between the terms thereof and of
any Loan  Document.  Subject to  acceptance  and recording  thereof  pursuant to
paragraph (d) of this Section,  from and after the effective  date  specified in
each Assignment and Acceptance the assignee  thereunder  shall be a party hereto
and to the Loan Allocation Agreement and, to the extent of the interest assigned
by such Assignment and  Acceptance,  have the rights and obligations of a Lender
under this Agreement and the Loan Allocation Agreement, and the assigning Lender
thereunder  shall, to the extent of the interest assigned by such Assignment and
Acceptance,  be released from its obligations  under this Agreement and the Loan
Allocation  Agreement (and, in the case of an Assignment and Acceptance covering
all of the assigning Lender's rights and obligations under this Agreement,  such
Lender  shall cease to be a party  hereto and  thereto but shall  continue to be
entitled to the benefits of Sections 2.16,  2.17, 2.18 and 9.03 hereof).  Except
for  assignments  pursuant to the Loan Allocation  Agreement,  any assignment or
transfer by a Lender of rights or obligations under this Agreement that does not
comply with this paragraph  shall be treated for purposes of this Agreement as a
sale by such  Lender  of a  participation  in such  rights  and  obligations  in
accordance with paragraph (e) of this Section.

                  (c) The  Administrative  Agent,  acting for this purpose as an
agent of the Borrower,  shall  maintain at one of its offices in The City of New
York a copy of each Assignment and Acceptance delivered to it and a register for
the  recordation  of the names and addresses of the Lenders,  and the Commitment
of, and principal amount of the Loans and LC Disbursements owing to, each Lender
pursuant to the terms hereof from time to time (the "Register").  The entries in
the Register shall be conclusive,  and Level 3, the Borrower, the Administrative
Agent,  the Issuing  Bank and the  Lenders  may treat each Person  whose name is
recorded in the Register  pursuant to the terms hereof as a Lender hereunder for
all purposes of this  Agreement,  notwithstanding  notice to the  contrary.  The
Register shall be available for inspection by the Borrower, the Issuing Bank and
any Lender,  at any reasonable time and from time to time upon reasonable  prior
notice.

                  (d)  Upon  its  receipt  of a duly  completed  Assignment  and
Acceptance  executed by an  assigning  Lender and an  assignee,  the  assignee's
completed  Administrative  Questionnaire (unless the assignee shall already be a
Lender  hereunder),  the processing and recordation fee referred to in paragraph
(b) of this  Section  and any  written  consent to such  assignment  required by
paragraph (b) of this Section,

                                                                             136

the Administrative  Agent shall accept such Assignment and Acceptance and record
the  information  contained  therein in the  Register.  No  assignment  shall be
effective  for  purposes of this  Agreement  unless it has been  recorded in the
Register as provided in this paragraph.

                  (e) Any Lender may,  without the consent of the Borrower,  the
Administrative   Agent,  the  Issuing  Bank  or  the  Swingline   Lender,   sell
participations  to one or more banks or other entities (a  "Participant") in all
or a portion of such  Lender's  rights  and  obligations  under  this  Agreement
(including  all or a  portion  of its  Commitment  and the  Loans  owing to it);
provided that (i) such Lender's  obligations  under this Agreement  shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such  obligations and (iii) Level 3, the Borrower,
the Administrative  Agent, the Issuing Bank and the other Lenders shall continue
to deal solely and directly  with such Lender in  connection  with such Lender's
rights and  obligations  under  this  Agreement.  Any  agreement  or  instrument
pursuant to which a Lender sells such a  participation  shall  provide that such
Lender shall retain the sole right to enforce the Loan  Documents and to approve
any amendment,  modification  or waiver of any provision of the Loan  Documents;
provided  that such  agreement or  instrument  may provide that such Lender will
not,  without  the  consent  of  the   Participant,   agree  to  any  amendment,
modification  or waiver  described in the first proviso to Section  9.02(b) that
affects such Participant. Subject to paragraph (f) of this Section, the Borrower
agrees that each Participant shall be entitled to the benefits of Sections 2.16,
2.17 and 2.18 to the same  extent as if it were a Lender  and had  acquired  its
interest by assignment  pursuant to paragraph (b) of this Section. To the extent
permitted  by law,  each  Participant  also shall be entitled to the benefits of
Section 9.08 as though it were a Lender,  provided such Participant agrees to be
subject to Section 2.19(c) as though it were a Lender.

                  (f) A Participant shall not be entitled to receive any greater
payment  under Section 2.16,  2.17,  or 2.18 than the  applicable  participating
Lender would have been  entitled to receive  with  respect to the  participation
sold  to  such  Participant,  unless  the  sale  of the  participation  to  such
Participant is made with the  Borrower's  prior written  consent.  A Participant
that would be a Foreign  Lender if it were a Lender shall not be entitled to the
benefits of Section  2.16 unless the  Borrower is notified of the  participation
sold to such Participant and such Participant agrees, for the benefit of the

                                                                             137

Borrower, to comply with Section 2.16(e) as though it were a Lender.

                  (g) Any  Lender  may at any time  pledge or assign a  security
interest  in all or any  portion of its rights  under this  Agreement  to secure
obligations  of such  Lender,  including  any  pledge  or  assignment  to secure
obligations  to a Federal  Reserve Bank, and this Section shall not apply to any
such pledge or assignment of a security  interest;  provided that no such pledge
or  assignment  of a security  interest  shall  release a Lender from any of its
obligations hereunder or substitute any such pledgee or assignee for such Lender
as a party hereto.

                  (h) Level 3 and the Borrowers  hereby  consent to the terms of
the Loan Allocation  Agreement,  the performance  thereof by the Lenders and any
assignments effected in accordance  therewith,  and each Borrower agrees to take
such actions  (including  the execution and delivery of  replacement  promissory
notes)  as  may  be  reasonably   necessary  to  effectuate   the   transactions
contemplated  thereby.  However,  neither the consent thereto by Level 3 and the
Borrowers,  nor the  compliance  thereof by any  Borrower  shall be construed to
alter,  change or amend the  obligations  secured under the applicable  Security
Document.

                  SECTION   9.05.   Survival.    All   covenants,    agreements,
representations  and  warranties  made by the Loan Parties in the Loan Documents
and in the  certificates  or other  instruments  delivered in connection with or
pursuant to this  Agreement or any other Loan  Document  shall be  considered to
have been  relied  upon by the  other  parties  hereto  and  shall  survive  the
execution  and  delivery of the Loan  Documents  and the making of any Loans and
issuance of any Letters of Credit,  regardless of any investigation  made by any
such other party or on its behalf and  notwithstanding  that the  Administrative
Agent,  the Issuing  Bank or any Lender may have had notice or  knowledge of any
Default  or  incorrect  representation  or  warranty  at the time any  credit is
extended  hereunder,  and shall continue in full force and effect as long as the
principal of or any accrued  interest on any Loan or any fee or any other amount
payable under this Agreement is  outstanding  and unpaid or any Letter of Credit
is outstanding  and so long as the  Commitments  have not expired or terminated.
The  provisions  of Sections  2.16,  2.17,  2.18 and 9.03 and Article VIII shall
survive and remain in full force and effect  regardless of the  consummation  of
the transactions contemplated hereby, the repayment of the Loans, the expiration
or termination of the Letters of Credit and the  Commitments or the  termination
of this Agreement or any provision hereof.

                  SECTION 9.06. Counterparts;  Integration;  Effectiveness. This
Agreement may be executed in  counterparts  (and by different  parties hereto on
different counterparts),  each of which shall constitute an original, but all of
which when taken together shall  constitute a single  contract.  This Agreement,
the other Loan Document and any separate letter  agreements with respect to fees
payable to the  Administrative  Agent  constitute the entire  contract among the
parties relating to the subject matter hereof and supersede any and all previous
agreements and understandings,  oral or written,  relating to the subject matter
hereof.  Except as  provided  in  Section  4.01,  this  Agreement  shall  become
effective when it shall have been executed by the Administrative  Agent and when
the  Administrative  Agent shall have received  counterparts  hereof which, when
taken  together,  bear the signatures of each of the other parties  hereto,  and
thereafter  shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. Delivery of an executed counterpart
of a signature page of this Agreement by telecopy shall be effective as delivery
of a manually executed counterpart of this Agreement.

                  SECTION 9.07.  Severability.  Any provision of this  Agreement
held to be invalid,  illegal or unenforceable  in any jurisdiction  shall, as to
such jurisdiction,  be ineffective to the extent of such invalidity,  illegality
or unenforceability without affecting the validity,  legality and enforceability
of the remaining provisions hereof; and the invalidity of a particular provision
in a particular  jurisdiction  shall not invalidate  such provision in any other
jurisdiction.

                  SECTION  9.08.  Right of Setoff.  If an Event of Default shall
have occurred and be  continuing,  each RC Lender and each of its  Affiliates is
hereby  authorized  at any time and from  time to time,  to the  fullest  extent
permitted by law, to set off and apply any and all deposits (general or special,
time or demand,  provisional or final) at any time held and other obligations at
any time owing by such Lender or  Affiliate  to or for the credit or the account
of the Borrower  against any of and all the  obligations  of the Borrower now or
hereafter  existing under this Agreement  held by such Lender,  irrespective  of
whether or not such Lender shall have made any demand under this  Agreement  and
although such obligations may be unmatured. The rights of each Lender under this
Section are in addition to other rights and remedies  (including other rights of
setoff) which such Lender may have.

                  SECTION 9.09.  Governing Law; Jurisdiction;
Consent to Service of Process.  (a)  This Agreement shall be
construed in accordance with and governed by the law of the
State of New York.

                  (b) Each of Level 3 and the Borrower  hereby  irrevocably  and
unconditionally  submits,  for  itself  and its  property,  to the  nonexclusive
jurisdiction  of the Supreme  Court of the State of New York sitting in New York
County and of the United States  District Court of the Southern  District of New
York,  and any  appellate  court from any thereof,  in any action or  proceeding
arising  out of or  relating  to  any  Loan  Document,  or  for  recognition  or
enforcement of any judgment,  and each of the parties hereto hereby  irrevocably
and  unconditionally  agrees  that all claims in  respect of any such  action or
proceeding  may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court.  Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other  jurisdictions  by suit on the judgment or in any other manner
provided by law.  Nothing in this  Agreement  or any other Loan  Document  shall
affect any right that the  Administrative  Agent, the Issuing Bank or any Lender
may otherwise have to bring any action or proceeding  relating to this Agreement
or any other Loan Document  against  Level 3, the Borrower or its  properties in
the courts of any jurisdiction.

                  (c) Each of Level 3 and the Borrower  hereby  irrevocably  and
unconditionally  waives, to the fullest extent it may legally and effectively do
so, any objection  which it may now or hereafter  have to the laying of venue of
any suit,  action or proceeding  arising out of or relating to this Agreement or
any other  Loan  Document  in any court  referred  to in  paragraph  (b) of this
Section.  Each of the parties hereto hereby  irrevocably  waives, to the fullest
extent permitted by law, the defense of an inconvenient forum to the maintenance
of such action or proceeding in any such court.

                  (d)  Each  party to this  Agreement  irrevocably  consents  to
service of process in the manner  provided for notices in Section 9.01.  Nothing
in this  Agreement or any other Loan Document will affect the right of any party
to this Agreement to serve process in any other manner permitted by law.

                  SECTION 9.10.  WAIVER OF JURY TRIAL.  EACH PARTY
HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN

                  SECTION  9.12.  Confidentiality.  Each  of the  Administrative
Agent,  the Issuing Bank and the Lenders agrees to maintain the  confidentiality
of the Information (as defined below),  except that Information may be disclosed

organization or any nationally  recognized rating agency that requires access to
information  about a Lender's  investment  portfolio in connection  with ratings
issued  with  respect  to  such  Lender.  For  the  purposes  of  this  Section,
"Information"  means  all  information  received  from  Level 3 or the  Borrower
relating  to Level 3 or the  Borrower  or its  business  (including  information
obtained through the exercise of a Lender's rights under Sections 5.01 and 5.09)
other than any such information that is available to the  Administrative  Agent,
the Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by
Level 3 or the Borrower.  Any Person required to maintain the confidentiality of
Information  as provided in this Section  shall be  considered  to have complied
with its  obligation  to do so if such Person has  exercised  the same degree of
care to maintain the  confidentiality  of such  Information as such Person would
accord to its own confidential information.

                  SECTION  9.13.   Interest  Rate  Limitation.   Notwithstanding
anything herein to the contrary,  if at any time the interest rate applicable to
any Loan, together with all fees, charges and other amounts which are treated as
interest on such Loan under applicable law (collectively  the "Charges"),  shall
exceed the maximum lawful rate (the "Maximum Rate") which may be contracted for,
charged,  taken,  received  or  reserved  by the  Lender  holding  such  Loan in
accordance with applicable law, the rate of interest  payable in respect of such
Loan hereunder,  together with all Charges payable in respect thereof,  shall be
limited to the Maximum Rate and, to the extent lawful,  the interest and Charges
that would have been  payable in respect of such Loan but were not  payable as a
result of the  operation of this Section shall be cumulated and the interest and
Charges  payable to such  Lender in respect of other  Loans or periods  shall be
increased (but not above the Maximum Rate therefor) until such cumulated amount,
together with interest  thereon at the Federal Funds  Effective Rate to the date
of repayment, shall have been received by such Lender.

                  SECTION  9.14.  Liability  of  Borrowers.  The  Borrowers  are
engaged as an integrated group in the telecommunications businesses conducted by
them, and each Borrower expects to derive benefit, directly or indirectly,  from
the credit extended by the Lenders  hereunder,  both in its individual  capacity
and as a member of such  integrated  group.  Each  Borrower  will be jointly and
severally  liable  for  the  payment  of all  Obligations  incurred  under  this
Agreement and the other Loan Documents,  including all obligations in respect of
principal,  interest,  reimbursement  of LC  Disbursements,  the posting of cash
Collateral, fees, expense reimbursements and indemnities. If, in any action

                                                                             142

or  proceeding  before any court of  competent  jurisdiction  under any state or
Federal  bankruptcy,  insolvency,  reorganization  or similar law  affecting the
rights of creditors generally, the joint and several obligations of any Borrower
in  respect  of  the  Obligations  would  otherwise,  taking  into  account  the
provisions of the Indemnity,  Subrogation and  Contribution  Agreement and other
rights of such Borrower under  applicable law, be held or determined to be void,
invalid  or  unenforceable,  or  subordinated  to the  claims  of  other  senior
creditors  of such  Borrower,  on  account  of the  amount  of  such  Borrower's
liability in respect of the  Obligations,  then,  notwithstanding  any provision
hereof to the  contrary,  the amount of such  liability  shall be  automatically
limited and reduced to the highest amount that is valid and  enforceable and not
subordinated  to the claims of other senior  creditors,  as  determined  by such
court in such action or proceeding.

                  SECTION 9.15.  Release of Subsidiaries  and Borrowers.  (a) If
(i) the Agent receives a certificate from the chief executive officer, the chief
financial officer or treasurer of the Company  certifying as of the date of that
certificate  that,  after  the  consummation  of the  transaction  or  series of
transactions  described in reasonable  detail  satisfactory to the Agent in such
certificate on such date, the Subsidiary Loan Party or Borrower, as the case may
be,  identified  in such  certificate  will no  longer  be a  Subsidiary  of the
Company,  (ii) such transactions are consummated on such date in accordance with
and  without  violating  the  provisions  of this  Agreement  or any other  Loan
Document, and (iii) in the case of a Borrower, any outstanding Letters of Credit
issued for the account of such Borrower have been, or arrangements  are in place
for  them  to  be,  terminated,  then  (x)  such  Subsidiary's  Guarantee  shall
automatically  terminate  and such  Subsidiary  shall cease to be a party to any
Loan Document (and  collateral  provided by such  Subsidiary for the Obligations
shall be released  and the  Collateral  Agent shall  execute  such  documents to
evidence such release) or (y) such Borrower  shall  automatically  cease to be a
party to this Agreement and the other Loan Documents.

                  (b) No such termination or cessation shall release, reduce, or
otherwise  adversely  affect the  obligations of any other Loan Party under this
Agreement,  any  other  Guarantee,  or any  other  Loan  Document,  all of which
obligations continue to remain in full force and effect.
                  (c) The Lenders shall,  at the Company's  expense execute such
documents as the Company may reasonably request

to evidence such termination or cessation, as the case may
be.

                  SECTION 9.16.  Special  Funding  Option.  (a)  Notwithstanding
anything to the contrary  contained herein, any Lender (for the purposes of this
Section  9.16,  a  "Granting  Lender")  may grant to a special  purpose  funding
vehicle (for the purposes of this Section 9.16, an "SPC") the option to make, on
behalf of such  Granting  Lender,  all or a  portion  of the  Loans  which  such
Granting  Lender  is  obligated  to  make (a  "Funding  Obligation")  under  the
Revolving Credit Facility,  such option to be exercisable in the sole discretion
of the SPC, provided, however, that

         (i) such Granting  Lender's  obligations  under this  Agreement and the
         Loan Documents shall remain unchanged, including without limitation the
         indemnification  obligations of the Granting Lender pursuant to Section
         9.03 hereof;

                  (ii) such Granting  Lender shall remain solely  responsible to
                  the other parties  hereto for the  performance  of all Funding
                  Obligations;

                  (iii) the  Borrower  and the  Lenders  shall  continue to deal
                  solely and directly  with such  Granting  Lender in connection
                  with such Granting  Lender's rights and obligations under this
                  Agreement;  the Agent shall continue to deal directly with the
                  Granting   Lender  as  agent  for  the  SPC  with  respect  to
                  distribution  of  payment  of  principal;  interest  and fees,
                  notices of Conversion and Continuation and all other matters;

                  (iv) such  Granting  Lender  shall  retain  the sole  right to
                  enforce the obligations of the Borrower  relating to its Loans
                  and its Notes and to approve any amendment,  modification,  or
                  waiver of any provisions of this Agreement, each of which may,
                  if so agreed in writing  between the  Granting  Lender and the
                  SPC,  require  the  prior  consent  of any such SPC  which has
                  exercised  the option to undertake  the Funding  Obligation in
                  connection  with  such  Granting   Lender's   Commitments  and
                  Obligations  owing thereto before the Granting Lender approves
                  any such amendment, modification or waiver;

         (v) the granting of such option shall not  constitute  an assignment to
         or participation of such SPC of or in the Granting Lender's Commitments
         and Obligations owing thereto;

                                                                             144

                  (vi)such SPC shall not become a Lender hereunder as a
                  result of the granting of such option;

         (vii) such SPC shall not become obligated or committed to make Loans as
         a result of the granting of such option;

                  (viii)  if such SPC  elects  not to  exercise  such  option or
                  otherwise  fails  to  make  all or any  part  of a  Loan,  the
                  Granting  Lender  shall retain its Funding  Obligation  and be
                  obligated  to make the entire Loan or any portion of such Loan
                  not made by such SPC; and

         (ix) any SPC may, with notice to, but without the prior written consent
         of, the Borrowers and the  Administrative  Agent and without paying any
         processing fee therefor,  assign all or a portion of its interests as a
         participant or  subparticipant  in any Loans to the Granting Bank or to
         any  financial   institutions   (consented  to  by  the  Borrowers  and
         Administrative  Agent) providing  liquidity and/or credit support to or
         for the account of such SPC to support the  funding or  maintenance  of
         Loans.

         (b) Loans  made by an SPC  hereunder  shall be deemed  to  satisfy  the
Funding  Obligation and utilize the Revolving Credit  Commitment of the Granting
Lender as if, and to the same  extent,  such  Loans  were made by such  Granting
Lender.

         (c) Each  party  hereto  agrees  that no SPC  shall be  liable  for any
indemnity  or payment  under this  Agreement  for which a Granting  Lender would
otherwise  be liable so long as, and to the extent  that,  the  Granting  Lender
provides such indemnity or makes such payment.  In furtherance of the foregoing,
each party hereto hereby agrees (which  agreement  shall survive the termination
of this  Agreement)  that,  prior to the date that is one year and one day after
the  payment  in  full of all  outstanding  commercial  paper  or  other  senior
Indebtedness of any SPC, it will not institute against, or join any other person
in instituting against,  such SPC any bankruptcy,  reorganization,  arrangement,
insolvency or liquidation proceedings under the laws of the United States or any
State thereof arising out of or relating to transactions under this Agreement or
the other Loan Documents.

         (d)  Notwithstanding   anything  to  the  contrary  contained  in  this
Agreement, an SPC may disclose on a confidential basis any nonpublic information
relating to Loans made by such SPC  hereunder to any rating  agency,  commercial
paper dealer or provider of any surety or guarantee to such SPC.

         (e) This  Section  9.16 may not be amended  without  the prior  written
consent of the  Granting  Lender on behalf of which such SPC has made all or any
part of its Loans which remain outstanding at the time of such amendment.
