1.  Basis of Presentation and Organization

         KMC Telecom Holdings, Inc. and its subsidiaries,  KMC Telecom Inc., KMC
Telecom II, Inc., KMC Telecom III,  Inc., and KMC Telecom of Virginia,  Inc. are
collectively  referred to herein as the Company.  All  significant  intercompany
accounts and transactions have been eliminated in consolidation.

         The unaudited  condensed  consolidated  financial  statements have been
prepared in accordance with generally accepted accounting principles for interim
financial  reporting.  Accordingly,  they do not include certain information and
note disclosures required by generally accepted accounting principles for annual
financial  reporting  and  should  be read in  conjunction  with  the  financial
statements  and notes  thereto of KMC Telecom  Holdings,  Inc. as of and for the
year ended December 31, 1998.

         The unaudited  interim  financial  statements  reflect all  adjustments
which management  considers  necessary for a fair presentation of the results of
operations for these periods.  The results of operations for the interim periods
are not necessarily indicative of the results for the full year.

         The balance  sheet of KMC Telecom  Holdings,  Inc. at December 31, 1998
was derived from the audited consolidated balance sheet at that date.

2.  Investments Held for Future Capital Expenditures

deposits and  commercial  paper with  maturities  of less than 90 days) of $16.8
million and debt securities (US government  obligations and commercial bonds due
within 1 year) of $12.2 million. All debt securities have been designated by the
Company as  held-to-maturity.  Accordingly,  such securities are recorded in the

carrying value of such held-to-maturity debt securities  approximated their fair
value.

5.  Due from Affiliate

         The Company has an  agreement in  principle  with KMC  Services  LLC, a
limited liability company wholly owned by Harold N. Kamine,  the Chairman of our
Board of Directors, pursuant to which KMC Services LLC will offer to the Company
financial and energy services which are related to the Company's  business.  KMC
Services LLC may also offer its services to third  parties in  jurisdictions  in
which the Company is not offering  telecommunications  services;  provided  that
such third parties are not competitors of the Company.  Initially,  KMC Services
LLC will  offer a  leasing  program  for  equipment  physically  installed  at a
customer's premises,  known as CPE equipment,  for the Company to integrate into
its ClearStarSMAdvantage  program, whereby the Company will be able to offer CPE
equipment for lease or sale to its customers. The equipment will be owned by KMC
Services  LLC  and  the  Company  will  have no  liability  for the  cost of the
equipment,  the financing related to it or the obligation for any lease charges.
Any such sale or lease will be between the  Company's  customer and KMC Services
LLC. The specific terms and conditions of the agreement between KMC Services LLC
and the Company are currently being  negotiated by the parties.  As of March 31,
1999,  the Company has loaned KMC Services  LLC an  aggregate  of  approximately
$400,000 pursuant to the agreement in principle.  The loan bears interest at the
rate of 10% per annum and is payable December 31, 1999.

7.  Lucent Loan and Security Agreement

         KMC Telecom III entered into a Loan and Security Agreement (the "Lucent
Facility") dated February 4, 1999 with Lucent Technologies Inc. ("Lucent") which
provides  for  borrowings  to  be  used  to  fund  the  acquisition  of  certain
telecommunications  equipment and related expenses. The Lucent Facility provides
for an  aggregate  commitment  of up to $600  million,  of which $125 million is
immediately available to purchase Lucent products and an additional $125 million
will  become  available  upon KMC Telecom  III's  receipt of an  additional  $35
million of funded  equity or  qualified  intercompany  loans,  as defined in the
agreement.  Further, up to an additional $350 million will be available upon (a)
additional  lenders  participating in the Lucent Facility and making commitments
to make loans so that Lucent's aggregate commitment does not exceed $250 million


                                       6
<PAGE>

and (b) the Company satisfying certain other requirements,  the most significant
of which is KMC Holdings  raising and contributing at least $300 million in high
yield debt or equity  (other than  disqualified  stock) to KMC Telecom  III. The
Lucent  Facility places certain  restrictions  upon KMC Telecom III's ability to
purchase  non-Lucent  equipment with proceeds from such  facility.  At March 31,
1999, no amounts had been borrowed under the Lucent Facility.

         Interest on  borrowings  under the Lucent  Facility is charged,  at the
option of KMC  Telecom  III,  at a floating  rate of LIBOR plus the  "Applicable
LIBOR Margin",  or at an alternative  base rate plus the  "Applicable  Base Rate
Margin" (as defined).  Such margins will be increased by 0.25% until KMC Telecom
III and its  subsidiaries  have completed  systems in fourteen  markets.  If KMC
Telecom III defaults on any payment due under the Lucent Facility,  the interest
rate will  increase  by four  percentage  points.  If any other event or default
shall occur,  the interest  rate will be  increased  by two  percentage  points.
Interest on each LIBOR loan is payable on each LIBOR  interest  payment  date in
arrears and interest on each base rate loan is payable quarterly in arrears. KMC
Telecom  III must pay an annual  commitment  fee on the  unused  portion  of the
Lucent Facility of 1.25%.

         Loans borrowed under the Lucent Facility amortize in amounts based upon
the following  percentages of the aggregate  amount of the loans drawn under the
Lucent Facility:

             Payment Dates                              Amortization
     ------------------------------                 ---------------------
     
     May 1, 2002 - February 1, 2003                    2.5% per quarter
     May 1, 2003 - February 1, 2006                    5.0% per quarter
     May 1, 2006 - February 1, 2007                    7.5% per quarter

         KMC Holdings has unconditionally guaranteed the repayment of up to $250
million  under the  Lucent  Facility  when such  repayment  is due,  whether  at
maturity, upon acceleration, or otherwise. KMC Telecom III Holdings, Inc., which
owns the shares of KMC  Telecom III and is  wholly-owned  by KMC  Holdings,  has
pledged the shares of KMC Telecom III to Lucent to collateralize its obligations
under the guaranty.  In addition,  KMC Telecom III has pledged all of its assets
to Lucent.

         The Lucent  Facility  contains  a number of  affirmative  and  negative
covenants  including,  among others,  covenants  restricting  the ability of KMC
Telecom III to consolidate or merge with any person, sell or lease assets not in
the ordinary course of business, sell or enter into any long term leases of dark
fiber,  redeem  stock,  pay  dividends  or make any  other  payments  (including
payments  of   principal  or  interest  on  loans)  to  KMC   Holdings,   create
subsidiaries, transfer any permits or licenses, or incur additional indebtedness
or act as  guarantor  for the  debt of any  other  person,  subject  to  certain
conditions.

         KMC Telecom III is required to comply with certain  financial tests and
maintain certain  financial  ratios,  including,  among others, a ratio of total
debt to contributed capital, certain minimum revenues, maximum EBITDA losses and
minimum EBITDA, maximum capital expenditures and minimum access lines, a maximum
total  leverage  ratio, a minimum debt service  coverage  ratio, a minimum fixed
charge coverage ratio and a maximum  consolidated  leverage ratio. The covenants
become more  restrictive upon the earlier of (i) July 1, 2002 and (ii) after KMC
Telecom III achieves positive EBITDA for two consecutive fiscal quarters.

         Failure to satisfy any of the financial  covenants  will  constitute an
event of default under the Lucent Facility,  permitting the lenders to terminate
the commitment and/or accelerate payment of outstanding indebtedness. The Lucent
Facility also includes other  customary  events of default,  including,  without
limitation,   a   cross-default   to  other  material   indebtedness,   material
undischarged  judgments,  bankruptcy,  loss of a material  franchise or material
license,  breach of representations  and warranties,  a material adverse change,
and the occurrence of a change of control.

8.  Preferred Stock and Warrant Issuances

Series E Preferred Stock

         On  February  4, 1999,  the Company  issued  25,000  shares of Series E
Senior  Redeemable,  Exchangeable,  PIK Preferred Stock (the "Series E Preferred
Stock")  to  Newcourt  Commercial  Finance  Corporation   ("Newcourt  Finance"),


                                       7
<PAGE>

generating  aggregate  gross proceeds of $22.9  million.  The Series E Preferred
Stock has a liquidation  preference  of $1,000 per share and an annual  dividend
equal to 14.5% of the liquidation  preference,  payable quarterly.  On or before
January 15, 2004,  the Company may pay dividends in cash or in additional  fully
paid and  nonassessable  shares of Series E Preferred  Stock.  After January 15,
2004,  dividends  must be paid in cash,  subject to certain  conditions.  Unpaid
dividends  accrue  at  the  dividend  rate  of the  Series  E  Preferred  Stock,
compounded quarterly.

         The Series E  Preferred  Stock must be  redeemed  on  February 1, 2011,
subject to the legal  availability  of funds  therefor,  at a redemption  price,
payable in cash, equal to the liquidation  preference  thereof on the redemption
date, plus all accumulated and unpaid dividends to the date of redemption. After
April 15, 2004,  the Series E Preferred  Stock may be  redeemed,  in whole or in
part, at the option of the Company,  at a redemption  price equal to 110% of the
liquidation  preference  of the Series E  Preferred  Stock plus all  accrued and
unpaid dividends to the date of redemption.  The redemption price declines to an
amount equal to 100% of the liquidation preference as of April 15, 2007.

         In  addition,  on or prior to April 15,  2002,  the Company may, at its
option,  redeem up to 35% of the  aggregate  liquidation  preference of Series E
Preferred  Stock with the proceeds of sales of its capital stock at a redemption
price equal to 110% of the  liquidation  preference on the redemption  date plus
accrued and unpaid dividends.

         The holders of Series E Preferred  Stock have voting  rights in certain
circumstances.  Upon the occurrence of a change of control,  the Company will be
required to make an offer to repurchase the Series E Preferred Stock for cash at
a purchase price of 101% of the liquidation  preference  thereof,  together with
all accumulated and unpaid dividends to the date of purchase.

         The Series E Preferred  Stock is not  convertible.  The Company may, at
the sole  option of the Board of  Directors  (out of funds  legally  available),
exchange  all,  but not less than all,  of the  Series E  Preferred  Stock  then
outstanding,  including any shares of Series E Preferred Stock issued as payment
for  dividends,  for a new  series of  subordinated  debentures  (the  "Exchange
Debentures") issued pursuant to an exchange debenture indenture.  The holders of
Series  E  Preferred  Stock  are  entitled  to  receive  on the date of any such
exchange,  Exchange Debentures having an aggregate principal amount equal to (i)
the total of the  liquidation  preference  for each share of Series E  Preferred
Stock  exchanged,  plus (ii) an amount equal to all accrued but unpaid dividends
payable on such share.

Series F Preferred Stock

         On  February  4, 1999,  the Company  issued  40,000  shares of Series F
Senior  Redeemable,  Exchangeable,  PIK Preferred Stock (the "Series F Preferred
Stock") to Lucent and Newcourt Finance,  generating  aggregate gross proceeds of
$38.9  million.  The Series F Preferred  Stock has a  liquidation  preference of
$1,000  per  share  and an  annual  dividend  equal to 14.5% of the  liquidation
preference,  payable  quarterly.  The  Company may pay  dividends  in cash or in
additional fully paid and nonassessable shares of Series F Preferred Stock.

         The Series F Preferred  Stock may be redeemed at any time,  in whole or
in part,  at the option of the Company,  at a redemption  price equal to 110% of
the  liquidation  preference on the redemption date plus an amount in cash equal
to all accrued and unpaid  dividends  thereon to the redemption  date.  Upon the
occurrence of a change of control, the Company will be required to make an offer
to purchase the Series F Preferred Stock for cash at a purchase price of 101% of
the  liquidation  preference  thereof,  together with all accumulated and unpaid
dividends to the date of purchase.

         The  holders of Series F  Preferred  Stock  have  voting  rights  under
certain circumstances.

         Upon the  earlier  of (i) the date that is sixty days after the date on
which the  Company  closes an  underwritten  primary  offering  of at least $200
million of its Common  Stock,  pursuant to an effective  registration  statement
under the  Securities  Act or (ii) February 4, 2001,  any  outstanding  Series F
Preferred Stock will  automatically  convert into Series E Preferred Stock, on a
one for one basis.

         The Company may, at the sole option of the Board of  Directors  (out of
funds legally  available),  exchange all, but not less than all, of the Series F
Preferred  Stock then  outstanding,  including  any shares of Series F Preferred


                                       8
<PAGE>

Stock issued as payment for dividends,  for Exchange Debentures.  The holders of
Series  F  Preferred  Stock  are  entitled  to  receive  on the date of any such
exchange,  Exchange Debentures having an aggregate principal amount equal to (i)
the total of the  liquidation  preference  for each share of Series F  Preferred
Stock  exchanged,  plus (ii) an amount equal to all accrued but unpaid dividends
payable on such share.

Warrants

         In  connection  with the  February  4, 1999  issuances  of the Series E
Preferred  Stock and the Series F  Preferred  Stock,  warrants  to  purchase  an
aggregate  of 24,660  shares of Common  Stock were sold to Newcourt  Finance and
Lucent.  The  aggregate  gross  proceeds  from the sale of  these  warrants  was
approximately  $3.2 million.  These  warrants,  at an exercise price of $.01 per
share, are exercisable from February 4, 2000 through February 1, 2009.

         In  addition,   the  Company  also   delivered  to  the  Warrant  Agent
certificates  representing  warrants to purchase an aggregate  of an  additional
107,228  shares  of Common  Stock at an  exercise  price of $.01 per share  (the
"Springing  Warrants").  The Springing  Warrants may become  issuable  under the
circumstances described in the following paragraph.

         If the Company  fails to redeem all shares of Series F Preferred  Stock
prior to the date (the "Springing Warrant Date") which is the earlier of (i) the
date  that is  sixty  days  after  the  date on  which  the  Company  closes  an
underwritten  primary  offering  of at least $200  million  of its Common  Stock
pursuant to an effective registration statement under the Securities Act or (ii)
February  4,  2001,  the  Warrant  Agent is  authorized  to issue the  Springing
Warrants to the Eligible  Holders (as defined in the warrant  agreement)  of the
Series E and Series F Preferred Stock. In the event the Company has redeemed all
outstanding  shares of Series F Preferred  Stock prior to the Springing  Warrant
Date,  the  Springing  Warrants  will not be issued and the  Warrant  Agent will
return the certificates to the Company.  To the extent the Company exercises its
option to exchange all of the Series F Preferred  Stock for Exchange  Debentures
prior to the  Springing  Warrant Date,  the  Springing  Warrants will not become
issuable.  Therefore,  as the  future  issuance  of the  Springing  Warrants  is
entirely  within the control of the Company and the likelihood of their issuance
is deemed to be remote, no value has been ascribed to the Springing Warrants.

9. Commitments and Contingencies

Purchase Commitments

         As  of  March  31,  1999,  the  Company  has  outstanding   commitments
aggregating    approximately    $133.0   million   related   to   purchases   of
telecommunications equipment and fiber optic cable and its obligations under its
agreements with certain suppliers.

Litigation

         By letter dated  August 29,  1997,  KMC Telecom  notified  I-Net,  Inc.
("I-NET")  that KMC  Telecom  considered  I-NET to be in default  under a Master
Telecommunications  System Rollout  Agreement,  dated as of October 1, 1996 (the
"I-Net  Agreement"),  as a result of I-NET's failure to provide design plans and
specifications for several systems for which it had agreed to provide such plans
and  specifications,  to properly  supervise  construction  of the systems or to
provide  personnel  with the  necessary  expertise  to manage the  projects.  On
February  12,  1998,  the Company  received a demand for  arbitration  from Wang
Laboratories,  Inc. ("Wang"),  the successor to I-NET. The demand seeks at least
$4.1 million.  The Company  believes that it has meritorious  defenses to Wang's
claims and has  asserted  counterclaims  seeking in excess of $2.5  million as a
result  of  I-NET's  defaults  under  the  I-NET   Agreement.   The  arbitration
proceedings are currently underway. The Company believes that resolution of this
matter will not have a material  adverse impact on its financial  condition.  No
assurance can be given, however, as to the ultimate resolution of this matter.

Redemption Rights

         Pursuant  to  a  stockholders  agreement,   certain  of  the  Company's
stockholders  and warrant  holders have "put rights"  entitling them to have the
Company repurchase their preferred and common shares and redeemable common stock
warrants for the fair value of such securities if no Liquidity Event (defined as


                                       9
<PAGE>

(i) an initial public offering with gross proceeds of at least $40 million, (ii)
the sale of substantially all of the stock or assets of the Company or (iii) the
merger or consolidation of the Company with one or more other  corporations) has
taken  place by the later of (x) October 22, 2003 or (y) 90 days after the final
maturity date of the Senior  Discount Notes.  The  restrictive  covenants of the
Senior Discount Notes limit the Company's ability to repurchase such securities.
All of the  securities  subject to such "put rights" are presented as redeemable
equity in the accompanying balance sheets.

         The redeemable preferred stock,  redeemable common stock and redeemable
common  stock  warrants are being  accreted up to their fair market  values from
their  respective  issuance dates to their earliest  potential  redemption  date
(October 22, 2003).  At March 31, 1999,  the aggregate  redemption  value of the
redeemable  equity  was  approximately   $175  million,   reflecting  per  share
redemption amounts of $727 for the Series A Preferred Stock, $286 for the Series
C Preferred Stock and $150 for the redeemable common stock and redeemable common
stock warrants.

10. Net Loss Per Common Share

         The following  table sets forth the  computation of net loss per common
share-basic (in thousands, except share and per share amounts):

         Options and  warrants to purchase an  aggregate  of 251,885 and 364,495
shares  of  common  stock  were  outstanding  as of March  31,  1998  and  1999,
respectively,  but a  computation  of diluted net loss per common  share has not
been presented, as the effect would be anti-dilutive.

11. Subsequent Events

         On April 30,  1999,  the Company  issued  35,000  additional  shares of
Series E Preferred  Stock and warrants to purchase an aggregate of 60,353 shares
of Common Stock at $.01 per share for aggregate proceeds of $35.0 million. These
shares of Series E Preferred  Stock have identical  rights and privileges as the
shares of Series E Preferred  Stock issued on February 4, 1999. The warrants are
exercisable from February 4, 2000 through February 1, 2009.


Item 2.  Management's Discussion and Analysis of Financial
         Condition and Results of Operations

     This Form 10-Q contains forward-looking  statements which involve risks and
uncertainties.  The Company's actual results may differ  significantly  from the
results discussed in the forward-looking  statements.  The following  discussion
should  be  read  in  conjunction  with  the  Unaudited  Condensed  Consolidated
Financial  Statements,  including the notes thereto,  included elsewhere in this
Form 10-Q.


                                       10
<PAGE>

Results of Operations

     As a result of the development  and rapid growth of the Company's  business
during the periods presented, the period-to-period  comparisons of the Company's
results of operations  are not  necessarily  meaningful and should not be relied
upon as an indication of future performance.

                  Three Months Ended March 31, 1999 Compared To
                        Three Months Ended March 31, 1998

         Revenue. Revenue increased from $2.8 million for the three months ended
March 31, 1998 (the "1998 First  Quarter") to $11.1 million for the three months
ended March 31,  1999 (the "1999 First  Quarter").  This  increase is  primarily
attributable  to the fact that we derived  revenues  from 22 markets  during the
entire  1999 First  Quarter  compared  to only 8 markets  during the entire 1998
First Quarter.  In addition,  each of our systems that generated revenues during
the 1998  First  Quarter  generated  increased  revenues  during  the 1999 First
Quarter.  Revenue for the 1998 and 1999 First Quarters included $2.1 million and
$6.2 million,  respectively, of revenue derived from resale of switched services
and an aggregate of $662,000 and $4.9 million (including $1.7 million of revenue
related to reciprocal compensation during the 1999 First Quarter), respectively,
of revenue  derived  from  on-net  special  access,  private  line and  switched
services.

         Network  Operating Costs.  Network  operating costs increased from $5.8
million in the 1998 First  Quarter to $19.7  million in the 1999 First  Quarter.
This  increase of $13.9  million was due primarily to the increase in the number
of  markets  in which we  operated  in the 1999 First  Quarter  and the  related
increases of $4.4 million in costs associated with providing resale services and
leasing  unbundled  network element  services,  $4.5 million in personnel costs,
$1.9 million in contracted network support costs, $1.1 million in consultant and
professional  services related costs and $2.0 million in facilities,  travel and
other direct operating costs.

         Costs associated with providing  on-net switched  services were greater
than revenue  generated from on-net switched services because we hired personnel
and staffed local offices prior to generating  revenue and obtaining  sufficient
revenue volume to cover such fixed operating costs.

         Costs  associated  with providing  resale services are greater than the
revenues  generated from these services because of narrow discounts  provided by
the incumbent local exchange carriers and because initial  installation  charges
by the incumbent local exchange  carrier to us are greater than our installation
charges to our  customers.  Resale is  primarily  an interim  strategy for us to
create  a  backlog  of  customers  to be  transitioned  to our  on-net  switched
facilities once our own switches become  commercially  operational.  We now have
switches in commercial  operation in 22 of our 23 markets. We are in the process
of  transitioning  the  majority  of our  resale  customers  to on-net  switched
services, but this can be a time-consuming task.

         Selling,  General  and  Administrative  Expenses  Selling,  general and
administrative  expenses  increased from $3.5 million for the 1998 First Quarter
to $12.0  million for the 1999 First  Quarter.  This  increase  of $8.5  million
resulted  primarily  from  increases of $3.5 million in  personnel  costs,  $1.6
million in  professional  costs  (consisting  primarily  of legal  costs),  $1.9
million in advertising  costs,  $900,000 in travel related expenses,  along with
increases in other marketing and general and  administrative  costs  aggregating
approximately $600,000.

         Stock Option Compensation Expense. Stock option compensation expense, a
non-cash charge,  increased from $1.1 million for the 1998 First Quarter to $3.9
million in the 1999 First  Quarter.  This increase  resulted from an increase in
the estimated fair value of the Company's Common Stock.

         Depreciation and  Amortization.  Depreciation and amortization  expense
increased  from $994,000 for the 1998 First Quarter to $5.5 million for the 1999
First Quarter primarily as a result of depreciation  expense associated with the
greater  number of  networks  commercially  operational  during  the 1999  First
Quarter.

         Interest  Expense.  Interest expense increased from $6.5 million in the
1998 First  Quarter to $10.3  million in the 1999 First  Quarter.  The  increase
resulted  primarily  from  increased  interest  charges  incurred  on the Senior
Discount  Notes for the full 1999  First  Quarter  compared  to only 2 months of
interest on the Senior  Discount Notes during the 1998 First  Quarter,  a higher
accreted  value of the  Senior  Discount  Notes in the 1999  First  Quarter  and


                                       11
<PAGE>

increased  interest charges related to the Senior Secured Credit Facility during
the 1999  First  Quarter as a result of  increased  borrowings  thereunder.  The
Company  capitalized  interest  of  $539,000  related  to  network  construction
projects  during  the 1999  First  Quarter  and  $605,000  during the 1998 First
Quarter.

         Net Loss. For the reasons  stated above,  net loss increased from $13.0
million for the 1998 First Quarter to $39.4 million for the 1999 First Quarter.

Liquidity and Capital Resources

         We have  incurred  significant  operating and net losses as a result of
the development  and operation of our networks.  We expect that such losses will
continue as we emphasize  the  development,  construction  and  expansion of our
networks and build our customer  base.  As a result,  there will not be any cash
provided by operations in the near future and we will need to fund the expansion
of our networks.  We have financed our operating losses and capital expenditures
with  equity  invested  by our  founders,  preferred  stock  placements,  credit
facility borrowings and the Senior Discount Notes.

         In  February  1999,  we issued  PIK  Preferred  Stock and  warrants  to
purchase  common  stock for  aggregate  gross  proceeds of $65.0  million to two
purchasers.  In April 1999, we issued  additional  shares of PIK Preferred Stock
and warrants to purchase common stock to one additional  purchaser for aggregate
gross proceeds of $35.0 million.

         In February 1999, our subsidiary  which will own the  approximately  14
additional  networks  which  we  currently  plan to  construct  over the next 12
months,   entered  into  a  secured  vendor   financing   facility  with  Lucent
Technologies  Inc. Under this Lucent Facility,  our subsidiary will be permitted
to borrow, subject to certain conditions,  up to an aggregate of $600.0 million,
primarily for the purchase from Lucent of switches and other  telecommunications
equipment.  After  giving  effect to the April 1999  issuance  of PIK  Preferred
Stock,  $250.0 million is available  under this facility.  The balance of $350.0
million  will become  available  only upon (a)  additional  lenders  agreeing to
participate in the facility so that Lucent's own aggregate  commitment  does not
exceed $250.0 million and (b) the Company satisfying certain other requirements,
the most  significant of which is the Company  raising,  and contributing to the
subsidiary, at least $300.0 million from the sale of high yield debt or equity.

         At March 31,  1999,  the  Company  had $75.0  million  of  indebtedness
outstanding under the Senior Secured Credit Facility,  and had $175.0 million in
borrowing capacity under the Senior Secured Credit Facility.

         Net cash provided by financing  activities  from  borrowings and equity
issuances was $89.5  million for the three months ended March 31, 1999.  Our net
cash used in operating and investment activities was $62.9 million for the three
months ended March 31, 1999.

         We made capital expenditures of $49.4 million in the three months ended
March 31, 1999. We currently plan to make  additional  capital  expenditures  of
approximately $230.0 million during the remainder of 1999. Continued significant
capital  expenditures are expected to be made thereafter.  The majority of these
expenditures is expected to be made for network construction and the purchase of
switches and related  equipment to facilitate  the offering of our services.  In
addition,  we expect to continue to incur  operating  losses while we expand our
business and build our customer base. Actual capital  expenditures and operating
losses will depend on numerous factors, including the nature of future expansion
and acquisition opportunities and factors beyond our control, including economic
conditions,   competition,  regulatory  developments  and  the  availability  of
capital.

         At March 31, 1999, the Company had outstanding  commitments aggregating
approximately  $133.0  million  related to the purchase of fiber optic cable and
telecommunications equipment as well as engineering services,  principally under
the Company's agreements with Lucent Technologies Inc.

         We  believe  that  our  cash,   investments  held  for  future  capital
expenditures  and borrowings  available under the Senior Secured Credit Facility
and the Lucent  Facility,  together  with the net  proceeds  from our April 1999
issuance of our PIK  Preferred  Stock will be  sufficient  to meet our liquidity
needs through the completion of our initial 23 networks. We currently anticipate
constructing  networks in  approximately 14 additional Tier III Markets over the
next 12  months  for  which we will  require  additional  financing.  Additional
sources of financing may include public or private equity or debt  financings by
the Company, capitalized leases and other financing arrangements.


                                       12
<PAGE>

         We can give no assurance that additional financing will be available to
us or, if available, that it can be obtained on a timely basis and on acceptable
terms. Failure to obtain such financing could result in the delay or abandonment
of some or all of our development and expansion plans and expenditures.

Year 2000 Compliance

         Similar to all  businesses,  we may be  affected  by the  inability  of
certain computer software to distinguish  between the years 1900 and 2000 due to
a  commonly-used  programming  convention.  Unless such programs are modified or
replaced  prior to January 1, 2000,  calculations  based on date  arithmetic  or
logical operations performed by such programs may be incorrect. In addition, the
Senior Secured Credit  Facility and the Lucent Facility impose certain Year 2000
compliance obligations on the Company.

         Management's  plan to address the effect of the Year 2000 issue focuses
on the following areas:  applications  systems (including our billing system and
financial  software),  infrastructure  (including personal computers and servers
used throughout the Company),  and other third party business partners,  vendors
and  suppliers.  Management's  analysis  and review of these areas is  comprised
primarily of the following phases: developing an inventory of hardware, software
and  embedded  chips;  assessing  the  degree to which  each  area is  currently
compliant  with Year 2000  requirements;  performing  renovations,  repairs  and
replacements as needed to attain compliance;  testing to ensure compliance; and,
developing  a  contingency  plan for each area if our initial  efforts to attain
compliance are either unsuccessful or untimely.

         Management completed the inventory and assessment phases of the project
during the fourth quarter of 1998. The renovation,  repair and replacement phase
and the testing  phase have  commenced;  however,  we expect to  continue  these
phases throughout 1999.

         Further,  we are currently in the process of  implementing  new billing
software  systems,  operational  software  systems and  financial  and personnel
software  systems.  Although  these  implementations  were made necessary by the
expansion of our  business  and were not  directly  related to Year 2000 issues,
they have  enabled us to  utilize  new  software  for these  purposes  which the
respective suppliers have certified as Year 2000 compliant.

         Costs  incurred  to date have  primarily  consisted  of labor  from the
redeployment  of existing  information  services and operational  resources.  We
expect to spend  approximately  $150,000 for these Year 2000 compliance  efforts
which will be  expensed as  incurred.  This amount does not include the costs of
the new billing  software,  operational  software and  financial  and  personnel
software  systems which we are  implementing as a result of the expansion of our
business.

         If the  software  applications  of the local  exchange  carriers,  long
distance  carriers  or others  on whose  services  we  depend or with  which our
systems interact are not Year 2000 compliant,  it could affect our systems which
could have a material  adverse effect on our business,  financial  condition and
results of operations.

         We have formed a  contingency  team to develop a work plan in the event
that  certain  programs and hardware  are not fully  compliant  and  operational
before  January 1, 2000.  The costs  associated  with this effort are  currently
being evaluated and cannot yet be determined. In the event that certain, or all,
of the contingency plans are deployed,  we will incur additional costs; however,
as contingency  plans are not yet developed,  we cannot determine these costs at
present.

         Although  we  do  not   presently   anticipate   a  material   business
interruption as a result of the Year 2000 issue,  the worst case scenario if all
of our Year 2000  efforts  fail  would  result in a daily  loss of  revenues  of
approximately $100,000 calculated based upon 1998 revenues.


Item 3.       Quantitative and Qualitative Disclosures About Market Risk

         Market risks relating to the Company's operations result primarily from
changes in interest rates. The substantial  majority of the Company's  long-term
debt bears interest at a fixed rate. However, the fair market value of the fixed
rate debt is sensitive to changes in interest  rates.  The Company is subject to
the risk that market  interest  rates will decline and the interest  expense due
under the fixed rate debt will exceed the  amounts  due based on current  market


                                       13

rates.  Under its current  policies,  the Company  does not utilize any interest
rate derivative instruments to manage its exposure to interest rate changes.

Item 1.  Legal Proceedings.

         Not Applicable.

Item 2.  Changes in Securities and Use of Proceeds.

         (a)  Not Applicable.

         (b)  Not Applicable.

         (c) On February 4, 1999, we issued units (the "Units") consisting of an
aggregate  of 25,000  shares of Series E Senior  Redeemable,  Exchangeable,  PIK
Preferred Stock, par value $.01 per share (the "Series E Preferred Stock"),  and
40,000 shares of Series F Senior Redeemable,  Exchangeable, PIK Preferred Stock,
par value $.01 per share (the "Series F Preferred  Stock"),  and  warrants  (the
"Warrants")  to purchase  approximately  24,660 shares of our Common Stock,  par
value $.01 per share,  for aggregate  gross proceeds of $65.0 million.  Newcourt
Commercial Finance Corporation  ("Newcourt  Finance"),  a subsidiary of Newcourt
Capital, Inc. ("Newcourt"), acquired all of the Series E Preferred Stock, 10,000
shares of the Series F Preferred Stock and Warrants to purchase 18,227 shares of
Common Stock.  Lucent Technologies Inc. ("Lucent") acquired 30,000 shares of the
Series F Preferred Stock and Warrants to purchase 6,433 shares of Common Stock.

     The sale of the Units to  Newcourt  Finance and Lucent was made in reliance
on the exemption  from  registration  provided by Section 4(2) of the Securities
Act, on the basis that the  transaction did not involve a public  offering.  The
offer and sale was made to only two institutional  investors.  In the Securities
Purchase  Agreement  applicable to the transaction,  Newcourt Finance and Lucent
each made representations as to their investment intent. The Securities Purchase
Agreement places  substantial  restrictions  upon transfer of the securities and
the certificates representing the securities have been legended to that effect.

         The  Warrants  issued as part of the Units  entitle  the holders of the
Warrants to  purchase  an  aggregate  of 24,660  shares of Common  Stock and are
exercisable  from  February 4, 2000 through  February 1, 2009 at a price of $.01
per share.

         On January 25, 1999, one individual exercised stock options to purchase
14,800 shares of Common Stock  previously  granted to that individual  under the
1998 Stock  Purchase and Option Plan for Key Employees of KMC Telecom  Holdings,
Inc. and Affiliates for aggregate gross proceeds of $333,000.  The sale was made
in reliance on the exemption from  registration  provided by Section 4(2) of the
Securities  Act,  on the basis  that the  transaction  did not  involve a public
offering. An Option Exercise and Investment  Representation  Statement signed by
the individual contains  representations as to his investment intent and imposes
substantial restrictions upon transfer of the securities.

Series E & F Unit shall be as follows: $22,909,265 of the consideration shall be
allocated to the Series E Preferred Stock, $9,721,235 of the consideration shall
be  allocated  to  the  Series  F  Preferred   Stock,   and  $2,369,500  of  the

          (b) The Issuer and Lucent  hereby  agree that for income tax  purposes
the allocation of the consideration  described in Section 2.01(b) for the Series
F  Preferred  Stock and the  Warrants  comprising  the Series F Unit shall be as
follows:  $29,163,706  of the  consideration  shall be allocated to the Series F
Preferred  Stock and  $836,294 of the  consideration  shall be  allocated to the

          (c) In light of the highly  conditional  nature of the purchase rights

purposes only,  none of the  consideration  for the Series E & F Unit or for the
Series F Unit will be allocated to the Springing Warrants.

carry on its business as now conducted. The Issuer is duly qualified or licensed
to do business as a foreign corporation in good standing in each jurisdiction in
which the  nature  of the  business  transacted  by it or the  character  of the
properties  owned or leased by it  requires  it to so  qualify  or be  licensed,
except  where the failure to so qualify or be  licensed  or be in good  standing
would not have a Material  Adverse Effect.  The copies of the Issuer's  Charter,

of the business  transacted  by it or the character of the  properties  owned or
leased by it requires it to so qualify or be  licensed,  except (i) as disclosed

call or put option, right of first refusal or offer or other right to acquire or
dispose  of any  shares  of  the  Issuer's  capital  stock  or  any  Convertible
Securities or Option Rights.  Except as described in Section 3.02(a) or Schedule

Convertible  Securities  or Option  Rights on  account  of the  issuance  of the
warrants.

          SECTION  3.03.   AUTHORIZATION;   NON-CONTRAVENTION.   The  execution,
delivery and performance by the Issuer of this Agreement,  the Warrant Agreement
and the Warrant Registration Rights Agreement,  the issuance,  sale and delivery
by the Issuer of the Securities and the execution of Springing  Warrants and the
amendments  to the  Charter  effected  by the  filing  of  the  Certificates  of
Designations are within the Issuer's corporate powers, have been duly authorized
by all  necessary  corporate  action,  require no action by or in respect of, or
filing with, any governmental body, agency or official (other than the filing of

not (i) contravene or constitute a default under any provision of applicable law
or regulation,  judgment, injunction, order or decree binding upon or applicable
to the Issuer,  (ii)  contravene  or  constitute a default  under the Charter or

contravene any material agreement,  judgment, injunction, order, decree or other
instrument binding upon the Issuer or any of its Subsidiaries.

          SECTION 3.04.  BINDING EFFECT.  This Agreement,  the Warrant Agreement
and the  Warrant  Registration  Rights  Agreement  have  been  duly  authorized,


                                       6
<PAGE>

executed and delivered by the Issuer and  constitute  valid and legally  binding
obligations  of the Issuer,  enforceable  in  accordance  with their  respective
terms,  except  as  enforceability  may be  limited  by  applicable  bankruptcy,
insolvency,   reorganization,   moratorium   and  similar  laws   affecting  the
enforcement of creditors'  rights generally and by general  principles of equity
(whether  enforcement  is sought by proceedings in equity or at law). The Issuer
has duly  authorized  the issuance,  sale and delivery of the  Securities to the
Purchasers  and,  when  issued  and  delivered  by the Issuer  pursuant  to this
Agreement  against  payment of the  consideration  set forth  herein,  and, with
respect to the Warrants,  countersigned  by the Warrant Agent (as defined in the
Warrant  Agreement),  and with respect to the Preferred Stock,  authenticated by
the  Transfer  Agent  (as  defined  in the  Certificate  of  Designations),  the
Securities will be validly issued,  fully paid and non-assessable free and clear
of all Liens and without violation of any preemptive rights. The Issuer has duly
authorized  the issuance and delivery of the  Springing  Warrants in  accordance
with the terms and conditions set forth in Section 2.4 of the Warrant Agreement,
and, when  countersigned by the Warrant Agent and delivered pursuant Section 2.4
of the Warrant Agreement,  the Springing Warrants will be validly issued,  fully
paid and non-assessable free and clear of all Liens and without violation of any
preemptive  rights. All of the shares of Common Stock to be issued upon exercise
of the Warrants and the Springing Warrants have been duly and validly authorized
and reserved for issuance upon such exercise and, when issued and delivered upon
exercise of the Warrants and the Springing Warrants in accordance with the terms
of the  Warrant  Agreement,  will be duly and  validly  issued,  fully  paid and
non-assessable  free  and  clear  of all  Liens  and  without  violation  of any
preemptive  rights.  All of the shares of Series E Preferred  Stock to be issued
upon  conversion  of the Series F  Preferred  Stock  have been duly and  validly
authorized and reserved for issuance upon such  conversion,  and when issued and
delivered  upon such  conversion  in  accordance  with the terms of the Series F
Certificate  of  Designation  will be duly and  validly  issued,  fully paid and
nonassessable.

          SECTION 3.05. GOVERNMENTAL REGULATION.  Except for the Securities Act,
the Exchange  Act and state  securities  laws,  the Issuer is not subject to any
federal or state or foreign law or regulation  limiting its ability to issue the
Securities or the Springing  Warrants or perform its obligations under the terms
of this  Agreement,  the  Warrant  Agreement,  the Warrant  Registration  Rights
Agreement,  the Securities or the Springing Warrants.  Except as may be required
pursuant to "blue sky laws" or as may be required  under the  Securities  Act or
the  Exchange  Act in  connection  with the  registration  of Warrant  Shares as
contemplated  under the  Warrant  Registration  Rights  Agreement,  no  notices,
reports or other filings are required to be made by the Issuer or any Subsidiary
with, nor are any consents,  registrations,  applications,  approvals,  permits,
licenses  or  authorizations  required  to be  obtained  by  the  Issuer  or any
Subsidiary  from, any public or  governmental  authority or other third party in
connection  with the  execution  and  delivery  of this  Agreement,  the Warrant
Agreement or the Warrant  Registration Rights Agreement,  or the consummation by
the Issuer of the transactions  contemplated  hereby or thereby, or the exercise
by the  Purchasers of their rights  hereunder,  except for any of the foregoing,
the failure of which to make or obtain would not have a Material  Adverse Effect
or adversely affect either of the Purchasers' rights hereunder.

          SECTION  3.06.   SOLICITATION.   Assuming  the   representations   and
warranties  of the  Purchasers  set forth in  Section  4.06  hereof are true and
correct in all material respects,  the offer and sale of the Securities pursuant
to this  Agreement  and the  issuance of the shares of Series E Preferred  Stock
upon  conversion of the Series F Preferred  Stock and the issuance of the shares
of Common  Stock  upon  exercise  of the  Warrants  and the  Springing  Warrants


                                       7

requirements of the Securities  Act. No form of general  solicitation or general
advertising  was used by the Issuer or, to the best of its knowledge,  any other
Person acting on its behalf,  in respect of the Securities or in connection with
the offer and sale of the  Securities.  Neither the Issuer nor any Person acting
on behalf of the Issuer has, either directly or indirectly,  sold or offered for
sale to any Person any of the  Securities or any other  similar  security of the
Issuer  except as  contemplated  by this  Agreement.  Neither the Issuer nor any
Person  acting  on its  behalf  has,  in  connection  with the  offering  of the
Securities,  engaged in any action that would require the registration under the
Securities  Act of the  offering  and sale of the  Securities  pursuant  to this
Agreement.

and  permits  issued  by  the  appropriate  federal,  state,  local  or  foreign
regulatory  authorities  necessary to conduct their  respective  businesses,  as
presently conducted, excepting any licence, certificate, authorization, approval
or permit, the failure to possess which,  singly or in the aggregate,  could not
reasonably be expected to result in a Material  Adverse Effect and (ii) have not
received any notice of proceedings relating to revocation or modification of any
such license, certificate,  authorization, approval or permit, nor is the Issuer
or any of its  Subsidiaries  in  violation  of, or in  default  under,  any such
license,  authorization,  approval  or permit  or any  decree,  order,  judgment
applicable to the Issuer or its Subsidiaries  the effect of which,  singly or in
the  aggregate,  could  reasonably  be expected to result in a Material  Adverse
Effect.

          SECTION 3.08.  COMPLIANCE  WITH LAWS.  Except as set forth on SCHEDULE
3.08 hereto and except as would not have a Material Adverse Effect, the business
of the  Issuer  and each of the  Subsidiaries  has been and is  presently  being
conducted in compliance  with all applicable  federal,  state,  county and local
ordinances, statutes, rules, regulations and laws (collectively "Laws").

          SECTION 3.09. LITIGATION. Except as set forth on SCHEDULE 3.09 hereto,
there are no pending actions, suits, proceedings, arbitrations or investigations
against  or  affecting  the  Issuer or any of its  Subsidiaries  or any of their
respective properties, assets or operations, or with respect to which the Issuer
or any such  Subsidiary  is  responsible  by way of  indemnity  or  otherwise (a
"Material Claim") that, if there is an adverse decision, could singly, or in the
aggregate,  with all such other actions,  suits,  investigations or proceedings,
have a Material  Adverse  Effect,  and, to the knowledge of the Issuer,  no such
actions, suits, proceedings or investigations are threatened.

          SECTION 3.10. PROPERTIES. Except as described in SCHEDULE 3.10 hereto,
the  Issuer and its  Subsidiaries  have good and  marketable  title to all their
material  property  and  assets,   free  and  clear  of  all  Liens  except  (a)
materialmen's, mechanics', carriers', workmen's, warehousemen's, repairmen's, or
other like Liens  arising in the  ordinary  course of business  with  respect to
moneys  not yet due and  payable;  (b) Liens for  current  Taxes not yet due and
payable or which are being contested in good faith and by proper procedures;  or
(c) Liens or minor imperfections of title that do not materially  interfere with
the use or materially detract from the value of such property.

          SECTION 3.11. TAX MATTERS.  The Issuer and its Subsidiaries have filed
all Tax  Returns  required  to be filed and are not in default in the payment of
any Taxes which were  payable  pursuant to such  returns or any  assessments  in
respect  thereof,  other  than any which the  Issuer or any such  Subsidiary  is
contesting in good faith by proper procedures.

<PAGE>

          SECTION  3.12.  PATENTS  AND  TRADEMARKS.  Each of the  Issuer and its
Subsidiaries  has  sufficient  right,   title  and  ownership  of  all  patents,

foregoing,  information,  proprietary rights and processes,  or shall be able to
obtain all such licenses and other authority  necessary or useful for the lawful
conduct of its business as it is contemplated to be conducted, without any known
conflicts  with the rights of  others.  No  stockholder,  officer,  director  or
employee  of the  Issuer or any  Subsidiary  owns any rights  therein  which are
competitive with those to be owned or used by the Company and any  Subsidiaries.
Neither  the  Issuer  nor any  Subsidiary  has  been  sued or  charged  with any
infringement of any patent,  license or permit or has knowledge of any basis for
any such claim.

          SECTION 3.13. LABOR MATTERS. (a) Neither the Issuer nor any Subsidiary
is party to any labor or collective  bargaining agreement and there are no labor
or collective  bargaining agreements which pertain to employees of the Issuer or
any Subsidiary.

          (b) No employees of the Issuer or any  Subsidiary  are  represented by
any labor  organization.  No labor  organization  or group of  employees  of the
Issuer or any Subsidiary has made a demand for recognition or certification, and
there are no representation or certification  proceedings or petitions seeking a
representation  proceeding presently pending or, to the knowledge of the Issuer,
threatened  to be brought or filed,  with the NLRB or any other labor  relations
tribunal or authority.  To the knowledge of the Issuer,  there are no organizing
activities  involving the Issuer or any  Subsidiary  pending with, or threatened
by, any labor organization.

          (c)  There  are  no  strikes,  work  stoppages,  slowdowns,  lockouts,
material  arbitrations  or material  grievances or other material labor disputes
pending or, to the knowledge of the Issuer,  threatened against or involving the
Issuer or any  Subsidiary.  Except as would not result in any  Material  Adverse
Effect,  there are no unfair labor  practice  charges,  grievances or complaints
pending or, to the  knowledge of the Issuer,  threatened  by or on behalf of any
employee or group of employees of the Issuer or any Subsidiary.

          SECTION  3.14.  ENVIRONMENTAL  MATTERS.  (a)  Except  as set  forth in
SCHEDULE  3.14,  (i) each of the  Issuer  and the  Subsidiaries  is in  material
compliance  with all  Environmental  Laws and (ii)  neither  the  Issuer nor any
Subsidiary has received any written communication from a governmental  authority
with respect to such compliance or the failure thereof.

          (b)  Except  as set  forth in  SCHEDULE  3.14,  (i) there is no civil,
criminal  or  administrative  action,  claim,  demand,  investigation  or notice
relating to a  violation  of an  Environmental  Law (an  "Environmental  Claim")
pending or, to the knowledge of the Issuer, threatened and (ii) to the knowledge
of the Issuer, there are no past or present actions, activities,  circumstances,
conditions,  events or incidents,  including,  without limitation,  the release,
emission, discharge or disposal of any chemical, pollutant,  contaminant, waste,
toxic substance,  petroleum or petroleum  product,  that would form the basis of
any  Environmental  Claim,  in  either  case  (A)  against  the  Issuer  or  any
Subsidiary,   (B)  against  any  person  or  entity  whose   liability  for  any
Environmental  Claim the Issuer or any  Subsidiary  has or may have  retained or
assumed either  contractually  or by operation of law, or (C) involving any real
or personal  property which the Issuer or any Subsidiary owns, leases or manages
except, in each case, as would not have a Material Adverse Effect.

          SECTION  3.15.  INSURANCE.  The  Issuer and its  Subsidiaries,  in the
reasonable  determination of the Issuer's management,  maintain with financially


                                       9
<PAGE>

sound  and  reputable  insurers  insurance  against  loss or damage of the kinds
customarily insured against by corporations of established reputation engaged in
the same or a similar business and similarly situated,  and of such types and in
such amounts as is customarily carried under similar circumstances by such other
corporations.

          SECTION  3.16.  YEAR 2000.  The Issuer has  engaged in a review of the
hardware and software  products used by the Issuer and the Subsidiaries in their
businesses  (collectively,  the "SOFTWARE")  which it believes to be adequate to
identify  any  material  deficiency  in "Year  2000  Capabilities".  "Year  2000
Capabilities"  means the ability of the  Software  (i) to manage and  manipulate
data  involving  dates,  including  single  century  formulas and  multi-century
formulas, and to not generate incorrect values or invalid results involving such
dates, (ii) to provide that all date-related user interface  functionalities and
data fields  include the  indication  of century,  and (iii) to provide that all
date-related data interface  functionalities  include the indication of century.
The Issuer is taking  appropriate  steps to identify exposure to deficiencies in
Year 2000 Capabilities resulting from the Year 2000 Capabilities of its vendors,
and to address them on a timely basis. In addition,  the Issuer believes that it
has adequate  resources to cause its Software to include Year 2000  Capabilities
which  currently may not contain them and that the costs of causing its Software
to  include  Year  2000  Capabilities  will  not be  material  to  the  Issuer's
consolidated financial position, results of operations or cashflows.

          SECTION 3.17. CERTAIN EXISTING AGREEMENTS.  Except as disclosed in any
document  or  report  filed by the  Issuer  with  the  Securities  and  Exchange
Commission  or on  SCHEDULE  3.17  hereto,  as of the date  hereof and as of the
Closing Date: (i) there are and will be no agreements providing for encumbrances
or  restrictions  that  would  be  grandfathered  under  Section  XI(C)  of  the
Certificates  of  Designations,  (ii)  there  is  and  will  be  no  outstanding
Indebtedness  that  would  be  grandfathered   under  Section  XI(A)(a)  of  the
Certificates of Designations, and (iii) there are and will be no agreements with
any  Affiliate  (as  defined  in  the   Certificates  of  Designations)  or  any
stockholder  agreements  (including  registration  rights  agreements or related
purchase  agreements) that would be  grandfathered  pursuant to Section XI(E) of
the Certificates of Designations.

          SECTION 3.18. FINANCIAL  INFORMATION.  (a) The Issuer has furnished to
each Purchaser the audited consolidated financial statements of the Issuer dated
as of  December  31,  1997  and for  the  year  then  ended,  and the  unaudited
consolidated  financial  statements for the fiscal  quarter ended  September 30,
1998 and for the month of October 1998,  (collectively,  the "FINANCIALS").  The
Financials  have  been  prepared  in  accordance  with GAAP  applied  on a basis
consistent  with that of  preceding  periods and are complete and correct in all
material  respects.  The Financials  fairly represent the Issuer's  consolidated
financial  position  as of the  dates  of the  balance  sheets  included  in the
Financials and its consolidated  results of operations for the periods indicated
therein.  There are no  omissions  from the  Financials  or any  other  facts or
circumstances  not  reflected  in the  Financials  which are or may be  material
according to GAAP.

          (b) Except as and to the extent expressly set forth in the Financials,
or the notes,  schedules or exhibits  thereto,  or as disclosed in the documents
filed by the Issuer  with the  Securities  and  Exchange  Commission,  (i) as of
September  30,  1998 (the  "BALANCE  SHEET  DATE"),  neither  the Issuer nor its
Subsidiaries  had any material  liabilities  or obligations  (whether  absolute,
contingent,  accrued or  otherwise)  that would be  required to be included on a
balance  sheet or in the  notes,  schedules  or  exhibits  thereto  prepared  in


                                       10
<PAGE>

accordance  with GAAP,  (ii) since the Balance  Sheet  Date,  the Issuer and its
Subsidiaries  have not incurred any such  material  liabilities  or  obligations
other than in the normal  course of business and (iii) since  December 31, 1997,
no event has occurred that has resulted in or is reasonably  likely to result in
a Material Adverse Effect.

          SECTION 3.19. DISCLOSURE. The Company has provided the Purchasers with
disclosure  about its and its  Subsidiaries'  business that in the aggregate did
not contain an untrue  statement of a material  fact or omit to state a material
fact necessary to make the statements in such disclosure not misleading.

                                   ARTICLE IV

                REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS

          Each Purchaser,  severally and not jointly, represents and warrants to
the Issuer as follows:

          SECTION 4.01.  ORGANIZATION.  It is duly  organized and existing under
the laws of its jurisdiction of organization.

          SECTION 4.02. AUTHORITY; NO OTHER ACTION. (a) The execution,  delivery

          (b) No action by or in respect of, or filing  with,  any  governmental
authority,  agency or official  is  required  for the  execution,  delivery  and
performance  by such  Purchaser of this  Agreement  or the Warrant  Registration
Rights Agreement.

          SECTION 4.03. NO CONFLICT. The execution,  delivery and performance by
it of this  Agreement  and the Warrant  Registration  Rights  Agreement  and the
consummation of the transactions contemplated hereby and thereby do not and will
not (i) violate its charter, bylaws or similar organizational  documents or (ii)
violate any applicable law, rule,  regulation,  judgment,  injunction,  order or
decree,  which  violation would (a) affect the validity of this Agreement or the
Warrant  Registration  Rights  Agreement or (b) individually or in the aggregate
impair the  ability of such  Purchaser  to perform in any  material  respect the
obligations which it has under this Agreement or the Warrant Registration Rights
Agreement.

          SECTION  4.04.   BINDING  EFFECT.   This  Agreement  and  the  Warrant
Registration Rights Agreement have been duly authorized,  executed and delivered
by  it  and,   except  as  limited   by   applicable   bankruptcy,   insolvency,


                                       11
<PAGE>

reorganization,  moratorium  and  similar  laws  affecting  the  enforcement  of
creditors'  rights  generally  and by  general  principles  of  equity  (whether
enforcement is sought by proceedings in equity or at law),  constitute valid and
binding  agreements  of such  Purchaser  enforceable  in  accordance  with their
respective terms.

          SECTION  4.05.  NO  DEFAULTS.  It is not in  violation of its charter,
bylaws or similar organizational  documents or in default under any provision of
applicable law or regulation or of any agreement,  judgment,  injunction, order,
decree or other instrument binding upon it, which violation or default (i) would
affect  the  validity  of this  Agreement  or the  Warrant  Registration  Rights
Agreement or (ii) would (individually or in the aggregate) impair the ability of
such Purchaser to perform in any material  respect the obligations  which it has
under this Agreement or the Warrant Registration Rights Agreement.

          SECTION  4.06.  PRIVATE  PLACEMENT.  (a) It  understands  that (i) the
offering and sale of the  Securities is intended to be exempt from  registration
under the Securities Act pursuant to Section 4(2) of the Securities Act and (ii)
there is no existing  public or other market for any of the Securities and there
can be no assurance  that it will be able to sell or dispose of such  Securities
purchased by it pursuant to this Agreement.

          (b)  It is an  "Accredited  Investor"  as  such  term  is  defined  in
Regulation D.

          (c) It has  sufficient  knowledge  and  experience  in  financial  and
business  matters so as to be capable of evaluating  the merits and risks of its
investment in the  Securities and it is capable of bearing the economic risks of
such investment, including a complete loss of its investment in the Securities.

          (d) It has had access to the  management and records of the Issuer and
has been  furnished  with all the  information  that it has  requested  from the
Issuer for determining whether to purchase the Securities and has been given the
opportunity  to ask  questions of, and receive  answers from,  management of the
Issuer  regarding  its  business  and  affairs  and  concerning  the  terms  and
conditions of the Securities and other related matters.

          (e) It understands  that the Securities and the shares of Common Stock
issuable  upon  exercise  of  the  Warrants  are  characterized  as  "restricted
securities"  under  the  federal  securities  laws  inasmuch  as they are  being
acquired  from the Issuer in a transaction  not involving a public  offering and
that under such laws and applicable  regulations  such  securities may be resold
without   registration   under  the  Securities  Act  only  in  certain  limited
circumstances.  In this  connection,  it represents that it is familiar with SEC
Rules  144 and  144A,  as  presently  in  effect,  and  understands  the  resale
limitations imposed thereby and by the Securities Act.

          (f) In addition to the  restrictions on transfer imposed by federal or
state securities  laws,  Lucent hereby covenants and agrees with the Issuer that
it will not transfer,  sell,  assign or pledge all or any part of the Securities
purchased  by it  hereunder  until the earlier of (i) one year after the date of
any future  issuance  and sale by the  Issuer of any high yield debt  securities
yielding gross proceeds to the Issuer of at least  $50,000,000 or (ii) August 4,
2000. Notwithstanding the foregoing, the Series F Preferred Stock may be held by
an Affiliate (as defined in the "Certificate of Designations") of Lucent that is
under its control.

          SECTION 6.01. COVENANTS OF THE ISSUER.

          (a)  ANNOUNCEMENTS.  No  party or any  Affiliate  (as  defined  in the
Certificates of Designations), officer or agent of the parties hereto shall make
any  announcement  concerning the transactions  contemplated  hereby without the
other parties' consent,  which consent may be withheld in their sole discretion;
PROVIDED,  HOWEVER, that any party or such Affiliate,  officer or agent may make
any  announcements  required  by  applicable  law so  long  as the  text of such

to announcements concerning the transactions contemplated hereby.

          (b) SECURITIES. The Issuer hereby covenants to each of the Purchasers,
that  from and  after  the date  hereof  and so long as any  Purchaser  owns any
Securities, the Issuer shall:

               (i) EXCHANGE OF CERTIFICATES. Upon surrender by the holder of any
          certificates   representing  Securities  (or  securities  issued  upon
          exchange,  conversion or exercise  thereof) for exchange or reissuance
          at the office of the Issuer,  cause to be issued in exchange  therefor
          new  certificates  in such  denomination  or  denominations  as may be
          requested for the same  aggregate  number of Securities (or securities
          issued upon exchange,  conversion or exercise thereof)  represented by
          the  certificates  so  surrendered  and  registered as such holder may
          request, subject to the provisions thereof.

               (ii) REPLACEMENT OF  CERTIFICATES.  Upon receipt by the Issuer of
          evidence reasonably satisfactory to it of loss, theft,  destruction or
          mutilation of any  certificate  evidencing  any of the  Securities (or


                                       14
<PAGE>

          securities issued upon exchange,  conversion or exercise thereof), and
          (in  case of loss,  theft  or  destruction)  of  indemnity  reasonably
          satisfactory to the Issuer, and upon the surrender and cancellation of
          such certificate,  if mutilated,  the Issuer shall make and deliver in
          lieu  of  such  certificate  a  new  certificate  for  the  number  of
          Securities (or securities issued upon exchange, conversion or exercise
          thereof),  as the  case  may  be,  evidenced  by  such  lost,  stolen,
          destroyed  or  mutilated  certificate  which  remains  outstanding.  A
          Purchaser's  (which term does not include any successors or assigns of
          the  Purchasers)  agreement of indemnity  shall  constitute  indemnity
          satisfactory  to the Issuer for the purposes of this  Section  6.01(b)
          without the need of any further surety or bond.

               (iii) GOVERNMENT AND OTHER APPROVALS.  Promptly  prepare,  submit
          and  file  with  all  public   and   governmental   authorities,   all
          applications,  notices,  registrations,  certificates,  statements and
          such other  information,  documents and instruments as may be required
          pursuant to any federal,  state or local law or rule or  regulation of
          the National Association of Securities Dealers, Inc. or any securities
          exchange,  in connection  with the  consummation  of the  transactions
          contemplated by this Agreement, including the effect of any dividends,
          exchange  or  conversion  rights,  anti-dilution  provisions  or Board
          control   contemplated  by  the  terms  of  the  Securities  or  other
          securities  of the  Issuer  which may be  acquired  by the  Purchasers
          pursuant to this  Agreement.  The Issuer shall use its best efforts to
          obtain any  necessary  consents or  approvals  from any  authority  in
          connection with the consummation of the  transactions  contemplated by
          this  Agreement,  including the effect of any  dividends,  exchange or
          conversion   rights,   anti-dilution   provisions   or  Board  control
          contemplated by the terms of the Securities.

          (c) ACCESS AND CONFIDENTIALITY.  Prior to the Closing Date, the Issuer
shall (and shall cause each of its  Subsidiaries  to) afford the  Purchasers and
their respective  representatives reasonable access during normal business hours
to its properties,  books,  contracts and records and personnel and advisors and
the Issuer shall (and shall cause each of the  Subsidiaries to) furnish promptly
to the  Purchasers  all  information  concerning  its  business  properties  and
personnel as the Purchasers or their respective  representatives  may reasonably
request,  provided  that any  review  will be  conducted  in a way that will not
interfere unreasonably with the conduct of the Issuer's business.

          (d)  REPORTS  TO  HOLDERS.  At all  times,  upon  the  request  of any
Purchaser so long as the Purchaser owns any Securities, the Company shall supply
to such  Purchaser  such  financial and other  information as such Purchaser may
reasonably  determine to be necessary  in order to permit  compliance  with Rule
144A in connection with a resale or a proposed resale of any of the Securities.

          (e)  RESERVATION  OF SERIES E PREFERRED  STOCK.  Issuer  shall use its
reasonable  best  efforts  with one year  after  the  Closing  Date to amend its
Charter to increase the number of authorized  shares of the Company's  preferred
stock and amend the Series E Certificate of Designations in order to provide for
the reservation of, and the Issuer hereby agrees to reverse, a sufficient number
of authorized but unissued  shares of Series E Preferred  Stock (i) to be issued
upon  conversion  of the Series F  Preferred  Stock and (ii) to provide  for the
payment of all  dividends  that may  accrue on the shares of Series E  Preferred
Stock then outstanding in additional shares of Series E Preferred Stock.

                                   ARTICLE II

                           ORIGINAL ISSUE OF WARRANTS

            SECTION 2.1. FORM OF WARRANT CERTIFICATES. Certificates representing
the Warrants (the "WARRANT  CERTIFICATES")  shall be  substantially  in the form
attached  hereto as Exhibit  A,  shall be dated the date on which  such  Warrant
Certificates  are  countersigned  by the  Warrant  Agent  and  shall  have  such
insertions as are appropriate or required or permitted by this Agreement and may
have such letters, numbers or other marks of identification and such legends and
endorsements stamped,  printed,  lithographed or engraved thereon as the Company
may deem  appropriate  and as are not  inconsistent  with the provisions of this
Agreement,  or as may be  required  to  comply  with any law or with any rule or
regulation  pursuant  thereto or with any rule or regulation  of any  securities
exchange on which the Warrants may be listed, or to conform to usage.

            Warrants shall be issued initially in registered form  substantially
in the form set forth in Exhibit A.

            The  definitive  Warrant  Certificates  shall  be  typed,   printed,
lithographed  or engraved or produced by any combination of these methods or may
be  produced  in any  other  manner  permitted  by the  rules of any  securities
exchange on which the Warrants may be listed,  all as determined by the officers
executing  such Warrant  Certificates,  as evidenced by their  execution of such
Warrant Certificates.

            SECTION 2.2.  RESTRICTIVE LEGENDS.  The Warrant Certificates
shall bear the following legend on the face thereof:

     THE WARRANTS REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
     THE U.S.  SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY
     STATE SECURITIES LAWS, AND ACCORDINGLY,  MAY NOT BE OFFERED,  SOLD, PLEDGED
     OR OTHERWISE  TRANSFERRED EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY
     ITS  ACQUISITION  HEREOF,  THE  HOLDER  (1)  REPRESENTS  THAT  (A)  IT IS A
     "QUALIFIED  INSTITUTIONAL  BUYER"  (AS  DEFINED  IN  RULE  144A  UNDER  THE
     SECURITIES  ACT) OR (B) IT IS AN  INSTITUTIONAL  "ACCREDITED  INVESTOR" (AS
     DEFINED  IN RULE  501(a)(1),  (2),  (3) OR (7) OF  REGULATION  D UNDER  THE
     SECURITIES ACT) (AN "INSTITUTIONAL  ACCREDITED INVESTOR"),  (2) AGREES THAT
     IT WILL NOT, WITHIN THE TIME PERIOD REFERRED TO IN RULE 144(k) (TAKING INTO
     ACCOUNT  THE  PROVISIONS  OF RULE  144(d)  UNDER  THE  SECURITIES  ACT,  IF
     APPLICABLE) RESELL OR OTHERWISE  TRANSFER THE WARRANTS  REPRESENTED BY THIS


                                       6
<PAGE>

     CERTIFICATE EXCEPT (A) TO KMC TELECOM HOLDINGS, INC. (THE "COMPANY") OR ANY
     SUBSIDIARY  THEREOF,  (B) TO A QUALIFIED  INSTITUTIONAL BUYER IN COMPLIANCE
     WITH RULE 144A UNDER THE SECURITIES ACT, (C) TO AN INSTITUTIONAL ACCREDITED
     INVESTOR  THAT,  PRIOR TO SUCH  TRANSFER,  FURNISHES TO THE WARRANT AGENT A
     SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO
     THE   RESTRICTIONS  ON  TRANSFER  OF  THE  WARRANTS   REPRESENTED  BY  THIS
     CERTIFICATE  (THE FORM OF WHICH  LETTER CAN BE  OBTAINED  FROM THE  WARRANT
     AGENT),  AND, AN OPINION OF COUNSEL  REASONABLY  ACCEPTABLE  TO THE COMPANY
     THAT SUCH TRANSFER IS IN COMPLIANCE  WITH THE SECURITIES  ACT, (D) PURSUANT
     TO  THE  EXEMPTION  FROM  REGISTRATION  PROVIDED  BY  RULE  144  UNDER  THE
     SECURITIES ACT (IF AVAILABLE) OR (E) PURSUANT TO AN EFFECTIVE  REGISTRATION
     STATEMENT  UNDER THE  SECURITIES ACT AND (3) AGREES THAT IT WILL DELIVER TO
     EACH  PERSON  TO WHOM THE  WARRANTS  REPRESENTED  BY THIS  CERTIFICATE  ARE
     TRANSFERRED  A  NOTICE  SUBSTANTIALLY  TO THE  EFFECT  OF THIS  LEGEND.  IN
     CONNECTION   WITH  ANY  TRANSFER  OF  THE  WARRANTS   REPRESENTED  BY  THIS
     CERTIFICATE WITHIN THE TIME PERIOD REFERRED TO ABOVE, THE HOLDER MUST CHECK
     THE  APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER
     OF SUCH TRANSFER AND SUBMIT THIS  CERTIFICATE TO THE WARRANT AGENT.  IF THE
     PROPOSED  TRANSFEREE IS AN INSTITUTIONAL  ACCREDITED  INVESTOR,  THE HOLDER
     MUST, PRIOR TO SUCH TRANSFER,  FURNISH TO EACH OF THE WARRANT AGENT AND THE
     COMPANY SUCH CERTIFICATIONS,  LEGAL OPINIONS OR OTHER INFORMATION AS EITHER
     OF THEM MAY REASONABLY  REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE
     PURSUANT TO AN  EXEMPTION  FROM,  OR IN A  TRANSACTION  NOT SUBJECT TO, THE
     REGISTRATION  REQUIREMENTS  OF THE  SECURITIES  ACT. THE WARRANT  AGREEMENT
     CONTAINS A PROVISION  REQUIRING THE WARRANT AGENT TO REFUSE TO REGISTER ANY
     TRANSFER OF THE WARRANTS  REPRESENTED  BY THIS  CERTIFICATE IN VIOLATION OF
     THE FOREGOING RESTRICTIONS.

            SECTION 2.3.  EXECUTION  AND DELIVERY OF WARRANT  CERTIFICATES.  (a)
Warrant Certificates evidencing Warrants to be issued under the Agreement,  each
Warrant to purchase  initially  0.471756 Common Shares,  may be executed,  on or
after the date of this  Agreement,  by the Company and  delivered to the Warrant
Agent for  countersignature,  and the Warrant Agent shall thereupon  countersign
and  deliver  such  Warrant  Certificates  upon  the  order  and at the  written
direction of the Company  signed by its Chairman of the Board,  Vice Chairman of
the Board, President,  Chief Operating Officer, Chief Financial Officer or Chief
Executive Officer to the purchasers thereof on the date of issuance. The Warrant
Agent is hereby  authorized to countersign and deliver  Warrant  Certificates as
required by this  Section  2.3,  Section  2.4,  Section  2.5 or by Section  3.3,
Article VI or Article VIII hereof.


                                       7
<PAGE>

            The Warrant  Certificates shall be executed on behalf of the Company
by its  Chairman  of the Board,  Vice  Chairman of the Board,  President,  Chief
Operating  Officer,  Chief Financial  Officer or Chief Executive  Officer either
manually or by facsimile  signature  printed thereon.  The Warrant  Certificates
shall be countersigned by manual signature of the Warrant Agent and shall not be
valid for any purpose unless so  countersigned.  In case any officer or director
of the Company  whose  signature  shall have been placed upon any of the Warrant
Certificates  shall cease to be such  officer or director of the Company  before
countersignature  by the Warrant  Agent and the issuance  and delivery  thereof,
such Warrant Certificates may nevertheless be countersigned by the Warrant Agent
and issued and  delivered  with the same force and effect as though  such person
had not ceased to be such officer or director of the Company.

            (b) On the  Closing  Date,  38,636  Warrants  shall be issued by the
Company and  registered in the name of Newcourt in connection  with the issuance
and sale to  Newcourt  of the  Series E & F Unit and  13,636  Warrants  shall be
issued by the Company and  registered in the name of Lucent in  connection  with
the issuance and sale to Lucent of the Series F Unit.

            Section  2.4.  SPRINGING  WARRANTS.  (a) In addition to the Warrants
described  in Section  2.3(b),  on the Closing  Date the Company  shall  execute
Warrant  Certificates  representing  227,273 Warrants,  registered in blank form
(the  "Springing  Warrants")  and shall deliver such  Springing  Warrants to the
Warrant Agent together with a written order  directing the Warrant Agent to hold
such Springing Warrants until either:

            (i)  the  Warrant  Agent  has  received  the  Springing  Notice,  as
            described below, accompanied by a certificate of the Transfer Agent,
            certifying  as to the amount of shares of Series F  Preferred  Stock
            that are  outstanding  as of such  date,  upon  receipt of which the
            Warrant  Agent  shall be  authorized  to  promptly  countersign  and
            deliver the Springing  Warrants to the holders of Eligible Shares in
            accordance with Section 2.4(c) below; or

            (ii) the Warrant Agent has received written notice from the Company,
            signed  by  the  President  or a  Vice  President  of  the  Company,
            certifying that the Company has redeemed all  outstanding  shares of
            Series F Preferred  Stock prior to the  Springing  Warrant  Date and
            accompanied by a certificate of the Transfer Agent,  certifying that
            no shares of Series F  Preferred  Stock are  outstanding  as of such
            date,  upon  receipt of which the  Warrant  Agent  shall  return the
            Warrant  Certificates  representing  the  Springing  Warrants to the
            Company for cancellation.

          (b) If the  Company  fails to redeem all shares of Series F  Preferred
Stock prior to the date (the  "Springing  Warrant Date") which is the earlier of
(i) the date that is sixty  days after the date on which the  Company  closes an
underwritten  primary  offering  of at least $200  million  of its Common  Stock
pursuant to an effective registration statement under the Securities Act or (ii)
February  4, 2001,  then the  holders of  Eligible  Shares  shall be entitled to


                                       8
<PAGE>

receive the Springing Warrants. Each holder of Eligible Shares shall be entitled
to  receive a number of  Springing  Warrants  equal to 227,273  multiplied  by a
fraction,  the numerator of which shall be the aggregate liquidation  preference
of such  holder's  Eligible  Shares and the  denominator  of which  shall be the
aggregate liquidation preference of all outstanding Eligible Shares. On or after
the  Springing  Warrant Date, a holder or holders of at least 10% or more of the
aggregate  outstanding Eligible Shares may deliver a notice to the Warrant Agent
in the form set forth in Exhibit C hereto (the "Springing Notice"),  accompanied
by a certificate of the Transfer Agent, certifying as to the number of shares of
Series F Preferred Stock that are outstanding as of such date.

            (c) Upon receipt of the Springing  Notice and the certificate of the
Transfer  Agent,  the Warrant  Agent shall be  authorized  and the Warrant Agent
shall, in coordination  with the Transfer Agent for the Series E Preferred Stock
and the Series F Preferred  Stock,  countersign  and deliver to each  registered
holder of Eligible Shares,  at such holder's address as set forth on the records
of the Transfer  Agent,  the number of Springing  Warrants  which such holder is
entitled to receive pursuant to Section 2.4(b).

            (d) The  Company  may from  time to time,  with the  consent  of the
holders of a majority  of the  shares of Series E  Preferred  Stock and Series F
Preferred  Stock then  outstanding,  execute and  deliver to the  Warrant  Agent
additional  Springing Warrants together with specific  instructions,  reasonably
acceptable to the Warrant Agent, with respect to the countersignature,  issuance
and delivery of such Springing  Warrants.  If the Company  executes and delivers
any  additional  Springing  Warrants to the Warrant  Agent,  references  in this
Section 2.4 to "227,273"  shall be deemed to be references to such larger number
as the Company specifies in writing to the Warrant Agent.

            SECTION 2.5. ADDITIONAL WARRANTS. From time to time, the Company may
issue and sell additional Warrants under this Agreement, together with shares of
Series E Preferred Stock or Series F Preferred Stock, to Additional  Purchasers;
PROVIDED THAT, any such Additional Purchaser shall agree to all of the terms and
conditions  of, and assume all of the rights and  obligations  of a  "Purchaser"
under, this Agreement and the Warrant Registration Rights Agreement, such action
to be evidenced by such  Additional  Purchaser  executing and  delivering to the
Company  and the  Warrant  Agent a  counterpart  to the  signature  page of this
Agreement  (in  the  form  attached   hereto  as  Exhibit  D)  and  the  Warrant
Registration  Rights Agreement (in the form set forth therein).  Other than such
Additional  Purchaser,  the Company and the Warrant  Agent with  respect to this
Agreement,  and the Company and such  Additional  Purchaser  with respect to the
Warrant  Registration  Rights  Agreement,  no  other  party  need  execute  such
counterparts  in order for them to be  effective.  The Company shall execute and
deliver Warrant  Certificates,  representing the amount of Warrants to be issued
pursuant to this Section 2.5, to the Warrant Agent for countersignature, and the
Warrant Agent shall thereupon  countersign and deliver such Warrant Certificates
upon the  order  and at the  written  direction  of the  Company  signed  by the
officers of the Company set forth in Section 2.03.

                                   ARTICLE III

                     EXERCISE PRICE AND EXERCISE OF WARRANTS

            SECTION 3.1.  EXERCISE PRICE. Each Warrant  Certificate  shall, when
countersigned  by the  Warrant  Agent,  initially  entitle  the Holder  thereof,
subject to the  provisions of this  Agreement,  to purchase the number of Common
Shares indicated  thereon at a purchase price (the "EXERCISE PRICE") of $.01 per
Common  Share,  subject to  adjustment  as provided in Section 4.1 and Article V
hereof.

            SECTION  3.2.  EXERCISE;  RESTRICTIONS  ON  EXERCISE.  At  any  time
beginning one year after the Closing Date and on or before the Expiration  Date,
any  outstanding  Warrants  may be  exercised on any Business Day by the Holders
thereof;  PROVIDED,  that the Warrant Registration  Statement is, at the time of
exercise,  effective  and  available  for the  exercise  of the  Warrants or the
exercise of such Warrants is exempt from the  registration  requirements  of the
Securities  Act. Any Warrants not exercised by 5:00 p.m., New York City time, on
the Expiration  Date shall expire and all rights of the Holders of such Warrants
shall terminate. Additionally, pursuant to Section 4.1(j)(ii) hereof and subject
to the conditions set forth therein, the Warrants shall expire and all rights of
the Holders of such Warrants shall  terminate in the event the Company merges or
consolidates  with or sells all or substantially  all of its property and assets
to a Person  (other  than an  Affiliate  of the  Company)  if the  consideration
payable  to  holders  of Common  Stock in  exchange  for their  Common  Stock in
connection with such merger, consolidation or sale consists solely of cash or in
the event of the dissolution, liquidation or winding up of the Company.

            SECTION 3.3. METHOD OF EXERCISE; PAYMENT OF EXERCISE PRICE. In order
to exercise all or any of the Warrants represented by a Warrant Certificate, the
Holder  thereof  must  surrender  for exercise  the Warrant  Certificate  to the
Warrant  Agent at its corporate  trust office  address set forth in Section 11.5
hereof,  with the  Subscription  Form set forth on the  reverse  of the  Warrant
Certificate  duly executed,  together with payment in full of the Exercise Price
then in  effect  for each  Common  Share  (or other  securities)  issuable  upon
exercise of the Warrants as to which a Warrant is exercised; such payment may be
made  by  wire  transfer,  in  cash or by  certified  or  official  bank or bank
cashier's  check  payable to the order of the  Company  and shall be made to the
Warrant  Agent at its corporate  trust office  address set forth in Section 11.5
hereof  prior to the close of business on the date the  Warrant  Certificate  is
surrendered to the Warrant Agent for exercise. Notwithstanding the foregoing, if
the Common Shares (or other  securities)  issuable upon exercise of the Warrants
are  registered  under  the  Exchange  Act,  the  Exercise  Price may be paid by
surrendering additional Warrants to the Warrant Agent having an aggregate Spread
equal to the  aggregate  Exercise  Price of the Warrants  being  exercised.  All
payments received upon exercise of Warrants shall be delivered to the Company by
the Warrant Agent as instructed in writing by the Company.  If less than all the
Warrants  represented by a Warrant  Certificate are exercised or surrendered (in


                                       10
<PAGE>

connection  with  a  cashless  exercise),  such  Warrant  Certificate  shall  be
surrendered  and a new Warrant  Certificate of the same tenor and for the number
of Warrants  which were not  exercised or  surrendered  shall be executed by the
Company  and  delivered  to the  Warrant  Agent  and  the  Warrant  Agent  shall
countersign the new Warrant Certificate, registered in such name or names as may
be  directed  in  writing  by the  Holder,  and shall  deliver  the new  Warrant
Certificate  to the Person or Persons  entitled  to receive  the same.  Upon the
exercise of any Warrants  following  the surrender of a Warrant  Certificate  in
conformity with the foregoing  provisions,  the Warrant Agent shall instruct the
Company to transfer  promptly  to the Holder or,  upon the written  order of the
Holder of such  Warrant  Certificate,  appropriate  evidence of ownership of any
Common Shares or other security or property to which it is entitled,  registered
or  otherwise  placed in such name or names as may be directed in writing by the
Holder,  and to deliver  such  evidence  of  ownership  to the Person or Persons
entitled  to receive  the same and  fractional  shares,  if any, or an amount in
cash,  in lieu of any  fractional  shares,  as  provided  in Section 4.5 hereof;
PROVIDED that the Holder of such Warrant shall be responsible for the payment of
any  transfer  taxes  required as the result of any change in  ownership of such
Warrants or the issuance of such Common  Shares other than to the Holder of such
Warrants  and any such  transfer  shall  comply with  applicable  law.  Upon the
exercise of a Warrant or Warrants,  the Warrant Agent is hereby  authorized  and
directed to  requisition  from any transfer  agent of the Common Shares (and all
such transfer  agents are hereby  authorized  to comply with all such  requests)
certificates  (bearing  the  legend  set  forth  in  Section  11.10  hereof,  if
applicable, unless a registration statement relating to such Common Shares filed
with the  Commission  shall  then be in effect  or the  Company  and the  Holder
exercising such Warrant or Warrants otherwise agree) for the necessary number of
Common Shares to which said Holder may be entitled.  The Company shall enter, or
shall cause any transfer  agent of the Common  Shares to enter,  the name of the
Person  entitled to receive the Common Shares upon exercise of the Warrants into
the  Company's  register  of  shareholders  within 14 days of such  exercise.  A
Warrant shall be deemed to have been exercised immediately prior to the close of
business on the date of the surrender for exercise,  as provided  above,  of the
Warrant  Certificate  representing such Warrant together with payment in full of
the  Exercise  Price  (or  surrender  of  sufficient  Warrant   Certificates  in
connection with a cashless exercise) and, for all purposes under this Agreement,
the Person entitled to receive any Common Shares  deliverable upon such exercise
shall,  as between  such Person and the  Company,  be deemed to be the Holder of
such Common  Shares of record as of the close of business on such date and shall
be entitled to receive,  and the Warrant Agent shall deliver to such Person, any
Common Shares to which such Person would have been entitled had such Person been
the registered holder on such date.


                                   ARTICLE IV

                                   ADJUSTMENTS

            SECTION 4.1.  ADJUSTMENTS.  The Exercise Price and the number of
Common Shares issuable upon exercise of each Warrant shall be subject to
adjustment from time to time as follows:

            (a)  DIVISIONS;  CONSOLIDATIONS;   RECLASSIFICATIONS.  In  case  the
Company shall, on or before the Expiration  Date, (i) issue any Common Shares in
payment of a dividend or other  distribution  with respect to its Common  Stock,
(ii) subdivide its issued and outstanding  Common Shares,  (iii) consolidate its


                                       11
<PAGE>

issued and  outstanding  Common Shares into a smaller number of shares,  or (iv)
reclassify  or convert  the Common  Shares  (other  than a  reclassification  in
connection with a merger, consolidation or other business combination which will
be governed by Section  4.1(j)),  then the number of Common  Shares  purchasable
upon  exercise  of each  Warrant  immediately  prior to the record date for such
issue or distribution or the effective date of such subdivision,  consolidation,
reclassification  or  conversion  shall be  adjusted  so that the Holder of each
Warrant  shall  thereafter  be entitled to receive the kind and number of Common
Shares which such Holder would have been entitled to receive after the happening
of any of the events described above had such Warrant been exercised immediately
prior to the happening of such event or any record date with respect thereto. An
adjustment  made  pursuant  to  this  Section  4.1(a)  shall  become   effective
immediately  after the effective  date of such event  retroactive  to the record
date, if any, for such event.

            (b)  RIGHTS;  OPTIONS;  WARRANTS.  In case the  Company  shall issue
rights, options,  warrants or convertible or exchangeable securities (other than
convertible or exchangeable securities subject to Section 4.1(a)) to all holders
of its Common Shares,  entitling them to subscribe for or purchase Common Shares
at a price per share which is lower (at the record date for such  issuance) than
the then Current  Market Value per Common  Share,  then the Company shall ensure
that at the time of such  issuance,  the same or a like offer or  invitation  is
made to the Holders of the Warrants as if their  Warrants had been  exercised on
the day immediately preceding the record date of such offer or invitation on the
terms (subject to any  adjustment  pursuant to Section 4.1(a) for a prior event)
on which such Warrants could have been exercised on such date;  PROVIDED that if
the Board so resolves, the Company shall not be required to ensure that the same
offer or invitation  is made to the Holders of the  Warrants,  but the number of
Common  Shares  thereafter  purchasable  upon the exercise of each Warrant shall
instead be adjusted and shall be determined by multiplying  the number of Common
Shares theretofore  purchasable upon exercise of each Warrant by a fraction, the
numerator  of  which  shall  be the  sum of (i)  the  number  of  Common  Shares
outstanding immediately prior to the issuance of such rights, options,  warrants
or convertible  or  exchangeable  securities  plus (ii) the number of additional
Common Shares which may be purchased or subscribed for upon  exercise,  exchange
or conversion of such rights,  options,  warrants or convertible or exchangeable
securities  and the  denominator  of which shall be the sum of (x) the number of
Common  Shares  outstanding  immediately  prior to the  issuance of such rights,
options,  warrants or convertible or exchangeable securities plus (y) the number
of shares which the total consideration received by the Company for such rights,
options,  warrants or  convertible or  exchangeable  securities so offered would
purchase at the then Current Market Value per Common Share.  Except as otherwise
provided  above,  such adjustment  shall be made whenever such rights,  options,
warrants or convertible or exchangeable  securities are issued, and shall become
effective retroactively  immediately after the record date for the determination
of  shareholders  entitled  to  receive  such  rights,   options,   warrants  or
convertible or exchangeable securities.

            (c) ISSUANCE OF COMMON SHARES AT LOWER  VALUES.  In case the Company
shall sell and issue any Common Share or Right (as defined below) (excluding (i)
any Right issued in any of the  transactions  described in Section 4.1(a) or (b)
above,  (ii) Common Shares issued pursuant to (x) any Rights  outstanding on the


                                       12
<PAGE>

date of this  Agreement  or any Rights  issued in any  transaction  described in
Section  4.1(a)  or (b) above  and (y) a Right,  if on the date  such  Right was
issued, the exercise, conversion or exchange price per Common Share with respect
thereto was at least equal to the then Current  Market  Value per Common  Share,
(iii)  any  Common  Shares  or  Rights  issued  (A) as  consideration  when  any
corporation or business is acquired,  merged into or becomes part of the Company
or a subsidiary of the Company or (B) in good faith in connection with any other
acquisition of assets, in each case in an arm's-length  transaction  between the
Company and a Person  other than an  Affiliate  of the  Company,  (iv) grants or
exercises of Rights granted to or exercised by employees, directors, consultants
or advisors of the Company or any of its subsidiaries for issuances of shares of
Common  Stock to such Persons and (v)  exercises of Rights by former  employees,
former directors, former consultants or former advisors of the Company or any of
its  subsidiaries  for issuances of shares of Common Stock to such Persons) at a
price per Common Share  (determined  in the case of any such Right,  by dividing
(x) the total  consideration  receivable by the Company in  consideration of the
sale and  issuance of such Right,  plus the total  consideration  payable to the
Company upon exercise,  conversion or exchange thereof,  by (y) the total number
of Common  Shares  covered by such Right) that is lower than the Current  Market
Value per Common  Share in effect  immediately  prior to such sale or  issuance,
then the number of Common  Shares  thereafter  purchasable  upon the exercise of
each Warrant  shall be  determined  by  multiplying  the number of Common Shares
theretofore  purchasable  upon  exercise  of such  Warrant  by a  fraction,  the
numerator of which shall be the number of Common Shares outstanding  immediately
after such sale or issuance and the  denominator of which shall be the number of
Common Shares  outstanding  immediately  prior to such sale or issuance plus the
number of Common Shares which the aggregate  consideration  received (determined
as provided  below) for such sale or  issuance  would  purchase at such  Current
Market Value per Common Share.  For purposes of this Section 4.1(c),  the Common
Shares which the holder of any such Right shall be entitled to subscribe  for or
purchase  shall be deemed to be issued  and  outstanding  as of the date of such
sale and issuance and the  consideration  received by the Company therefor shall
be deemed to be the  consideration  received by the Company for such Right, plus
the  consideration  or  premiums  stated in such Right to be paid for the Common
Shares  covered  thereby.  In case the  Company  shall  sell and issue any Right
together  with one or more  other  securities  as part of a unit at a price  per
unit,  then in determining  the "price per Common Share" and the  "consideration
received by the  Company"  for  purposes of the first  sentence of this  Section
4.1(c),  the Board shall  determine,  in good faith, the fair value of the Right
then being sold as part of such unit. For purposes of this paragraph,  a "RIGHT"
shall mean any right,  option,  warrant or convertible or exchangeable  security
containing  the Right to  subscribe  for or acquire one or more  Common  Shares,
excluding the Warrants. This Section 4.1(c) shall not apply to: (i) the exercise
of Warrants,  or the conversion or exchange of other  securities  convertible or
exchangeable  for Common Shares;  or (ii) Common Shares issued upon the exercise
of Rights or warrants issued to all holders of Common Shares.

            (d)   DISTRIBUTIONS  OF  DEBT,   ASSETS,   SUBSCRIPTION   RIGHTS  OR
CONVERTIBLE  SECURITIES.  In case the Company shall make a  distribution  to all
holders of its Common  Shares of evidences of its  indebtedness,  or assets,  or
other distributions (excluding distributions in connection with the dissolution,
liquidation  or  winding-up  of the  Company  which shall be governed by Section


                                       13
<PAGE>

4.1(j) and  distributions of securities  referred to in Section 4.1(a),  Section
4.1(b) or  Section  4.1(c)),  then,  in each case,  the number of Common  Shares
purchasable  after such record date upon the exercise of each  Warrant  shall be
determined  by  multiplying  the number of Common  Shares  purchasable  upon the
exercise of such  Warrant  immediately  prior to such record date by a fraction,
the  numerator  of which  shall be the  Current  Market  Value per Common  Share
immediately  prior to the record date for such  distribution and the denominator
of which shall be the Current Market Value per Common Share immediately prior to
the record date for such distribution less the then fair value (as determined in
good faith by the Board) of the  evidences of  indebtedness,  or assets or other
distributions so distributed  attributable to one Common Share.  Such adjustment
shall be made whenever any such distribution is made, and shall become effective
on the date of distribution retroactive to the record date for the determination
of shareholders entitled to receive such distribution.

            (e) EXPIRATION OF RIGHTS,  OPTIONS AND CONVERSION  PRIVILEGES.  Upon
the  expiration  of any  rights,  options,  warrants or  conversion  or exchange
privileges  (including,  without  limitation,  any Rights) that have  previously
resulted  in an  adjustment  hereunder,  if any  thereof  shall  not  have  been
exercised,  exchanged or converted,  the Exercise Price and the number of Common
Shares issuable upon the exercise of each Warrant shall,  upon such  expiration,
be readjusted and shall  thereafter,  upon any future exercise,  be such as they
would  have  been  had  they  been  originally  adjusted  (or had  the  original
adjustment  not been  required,  as the  case may be) as if (i) the only  Common
Shares so issued were the Common Shares,  if any,  actually  issued or sold upon
the  exercise,  exchange or  conversion  of such  rights,  options,  warrants or
conversion or exchange rights (including,  without  limitation,  any Rights) and
(ii) such  Common  Shares,  if any,  were  issued or sold for the  consideration
actually received by the Company upon such exercise, exchange or conversion plus
the consideration,  if any, actually received by the Company for issuance,  sale
or grant of all such rights, options,  warrants or conversion or exchange rights
(including, without limitation, any Rights) whether or not exercised.

            (f) CURRENT MARKET VALUE. For the purposes of any computation  under
this  Article IV, the  "CURRENT  MARKET  VALUE" per Common Share or of any other
security  (herein  collectively  referred to as a "security") at any date herein
specified shall be:

            (i) if the security is not  registered  under the Exchange  Act, the
      value of the security (1) most recently determined as of a date within the
      six months preceding such date by an Independent Financial Expert selected
      by the Board in accordance with the criteria for such valuation set out in
      Section  4.1(k),  or (2) if no such  determination  shall  have  been made
      within such six-month  period or if the Company so chooses,  determined as
      of such a date by an Independent Financial Expert selected by the Board in
      accordance with the criteria for such valuation set out in Section 4.1(k),
      or

            (ii) if the  security is  registered  under the  Exchange  Act,  the
      average of the daily market prices of the security for the 20  consecutive
      trading days immediately  preceding such date or, if the security has been
      registered  under the  Exchange Act for less than 20  consecutive  trading
      days before such date, then the average of the daily market prices for all


                                       14
<PAGE>

      of the trading  days before  such date for which daily  market  prices are
      available. The market price for each such trading day shall be: (A) in the
      case  of a  security  listed  or  admitted  to  trading  on  any  national
      securities exchange, the closing sales price, regular way, on such day, or
      if no sale takes  place on such day,  the  average of the  closing bid and
      asked prices on such day on the principal national  securities exchange on
      which such security is listed or admitted,  as determined by the Board, in
      good faith,  (B) in the case of a security  not then listed or admitted to
      trading on any national securities exchange,  the last reported sale price
      on such day,  or if no sale takes  place on such day,  the  average of the
      closing  bid and asked  prices on such day,  as  reported  by a  reputable
      quotation source designated by the Company,  (C) in the case of a security
      not then listed or admitted to trading on any national securities exchange
      and as to which no such  reported  sale price or bid and asked  prices are
      available,  the average of the  reported  high bid and low asked prices on
      such day, as reported by a reputable  quotation service, or a newspaper of
      general  circulation  in the Borough of  Manhattan,  City and State of New
      York  customarily  published  on  each  Business  Day,  designated  by the
      Company,  or, if there shall be no bid and asked  prices on such day,  the
      average of the high bid and low asked prices, as so reported,  on the most
      recent day (not more than 30 days prior to the date in question) for which
      prices have been so reported  and (D) if there are no bid and asked prices
      reported  during the 30 days prior to the date in  question,  the  Current
      Market Value of the security  shall be  determined as if the security were
      not registered under the Exchange Act.

            (g)  CONSIDERATION   RECEIVED.   For  purposes  of  any  computation
respecting  consideration  received  pursuant to this Section 4.1, the following
shall apply:

            (i) in the case of the  issuance  of Common  Shares  for  cash,  the
      consideration  shall be the amount of such cash,  PROVIDED that in no case
      shall  any  deduction  be made  for any  commissions,  discounts  or other
      expenses  incurred  by the Company  for any  underwriting  of the issue or
      otherwise in connection therewith;

            (ii)  in  the  case  of  the   issuance  of  Common   Shares  for  a
      consideration in whole or in part other than cash, the consideration other
      than  cash  shall  be  deemed  to be the  fair  market  value  thereof  as
      determined  in good  faith by the Board  (irrespective  of the  accounting
      treatment thereof),  whose determination shall be conclusive and described
      in reasonable detail in a board resolution which shall be provided as soon
      as practicable thereafter to the Warrant Agent; and

            (iii) in the case of the  issuance of rights,  options,  warrants or
      securities convertible into or exchangeable for Common Shares, (including,
      without  limitation,  any Rights),  the aggregate  consideration  received
      therefor shall be deemed to be the  consideration  received by the Company
      for  the  issuance  of  such  rights,  options,   warrants  or  securities
      convertible  into or exchangeable  for Common Shares,  plus the additional
      minimum  consideration,  if any, to be  received  by the Company  upon the
      exercise,  conversion or exchange thereof (the  consideration in each case
      to be determined in the same manner as provided in clauses (i) and (ii) of
      this Section 4.1(g)).


                                       15

            (h) DE MINIMIS  ADJUSTMENTS.  No  adjustment in the number of Common
Shares  purchasable  hereunder shall be required  unless such  adjustment  would
require an increase  or  decrease of at least one percent  (1%) in the number of
Common Shares purchasable upon the exercise of each Warrant; PROVIDED,  HOWEVER,
that any adjustments  which by reason of this Section 4.1(h) are not required to
be made  shall be carried  forward  and taken  into  account  in any  subsequent
adjustment.  All calculations  shall be made to the nearest  one-thousandth of a
share.

            (i)  ADJUSTMENT  OF EXERCISE  PRICE.  Whenever  the number of Common
Shares  purchasable  upon the exercise of each  Warrant is  adjusted,  as herein
provided,  the  Exercise  Price per Common Share  payable upon  exercise of such
Warrant  shall be adjusted  (calculated  to the  nearest  $.01) so that it shall
equal the price determined by multiplying such Exercise Price  immediately prior
to such  adjustment  by a fraction the numerator of which shall be the number of
Common Shares purchasable upon the exercise of each Warrant immediately prior to
such  adjustment  and the  denominator  of which  shall be the  number of Common
Shares so purchasable  immediately  thereafter.  Following any adjustment to the
Exercise Price pursuant to this Article IV, the amount  payable,  when adjusted,
together  with the amount paid in connection  with the original  issuance of the
Warrants, shall never be less than the par value per Common Share at the time of
such adjustment.

            If after an  adjustment,  a Holder of a Warrant upon  exercise of it
may receive  shares of two or more  classes in the capital of the  Company,  the
Company shall  determine the  allocation of the adjusted  Exercise Price between
such  classes of shares in a manner that the Board deems fair and  equitable  to
the Holders.  After such  allocation,  the exercise  privilege  and the Exercise
Price of each class of shares shall thereafter be subject to adjustment on terms
comparable to those applicable to Common Shares in this Article IV.

            Such adjustment shall be made successively whenever any event listed
above shall occur.

            (j)  CONSOLIDATION,  MERGER,  ETC. (i) Subject to the  provisions of
Subsection (ii) below of this Section 4.1(j),  in case of the  consolidation  of
the Company  with,  or merger of the Company with or into, or of the sale of all
or substantially all of the properties and assets of the Company to, any Person,
and in connection therewith consideration is payable to holders of Common Shares
(or other  securities  or property  purchasable  upon  exercise of  Warrants) in
exchange therefor, the Warrants shall remain subject to the terms and conditions
set forth in this  Agreement and each Warrant shall,  after such  consolidation,
merger or sale, entitle the Holder to receive upon exercise the number of shares
in the capital or other  securities or property  (including cash) of or from the
Person  resulting from such  consolidation  or surviving such merger or to which
such sale  shall be made or of the  parent of such  Person,  as the case may be,
that would have been distributable or payable on account of the Common Shares if
such  Holder's  Warrants had been  exercised  immediately  prior to such merger,
consolidation or sale (or, if applicable,  the record date therefor); and in any
such case the  provisions  of this  Agreement  with  respect  to the  rights and
interests thereafter of the Holders of Warrants shall be appropriately  adjusted


                                       16
<PAGE>

by the Board in good faith so as to be  applicable,  as nearly as may reasonably
be, to any shares,  other securities or any property  thereafter  deliverable on
the exercise of the Warrants.

            (ii)  Notwithstanding  the  foregoing,  (x) if the Company merges or
      consolidates  with, or sells all or substantially  all of its property and
      assets to,  another  Person  (other than an  Affiliate of the Company) and
      consideration is payable to holders of Common Shares in exchange for their
      Common Shares in connection with such merger,  consolidation or sale which
      consists  solely  of  cash,  or  (y)  in the  event  of  the  dissolution,
      liquidation  or winding up of the  Company,  then the  Holders of Warrants
      shall be entitled to receive distributions on the date of such event on an
      equal basis with holders of Common  Shares (or other  securities  issuable
      upon  exercise of the  Warrants)  as if the  Warrants  had been  exercised
      immediately  prior to such event, less the Exercise Price. Upon receipt of
      such payment, if any, the rights of a Holder shall terminate and cease and
      such  Holder's  Warrants  shall  expire.  In  case  of  any  such  merger,
      consolidation or sale of assets, the surviving or acquiring Person and, in
      the event of any  dissolution,  liquidation  or winding up of the Company,
      the Company  shall deposit  promptly with the Warrant Agent the funds,  if
      any,  necessary to pay the Holders of the Warrants.  After receipt of such
      deposit from such Person or the Company and after  receipt of  surrendered
      Warrant Certificates, the Warrant Agent shall make payment by delivering a
      check in such amount as is appropriate  (or, in the case of  consideration
      other  than cash,  such other  consideration  as is  appropriate)  to such
      Person  or  Persons  as it may  be  directed  in  writing  by  the  Holder
      surrendering such Warrants.

            (k) If required  pursuant to Section  4.1(f)(i),  the Current Market
Value shall be deemed to be equal to the value set forth in the Value Report (as
defined below) as determined by an Independent  Financial Expert, which shall be
selected by the Board in its sole  discretion,  and retained on customary  terms
and  conditions,  using  one or more  valuation  methods  that  the  Independent
Financial  Expert,  in its best  professional  judgment,  determines  to be most
appropriate.  The Company  shall use its  reasonable  best  efforts to cause the
Independent  Financial  Expert to  deliver  to the  Company,  with a copy to the
Warrant Agent,  within 45 days of the appointment of the  Independent  Financial
Expert,  a value  report  (the "VALUE  REPORT")  stating the value of the Common
Shares and other securities or property of the Company,  if any, being valued as
of the  Valuation  Date and  containing  a brief  statement as to the nature and
scope of the examination or investigation  upon which the determination of value
was made.  The Warrant Agent shall have no duty with respect to the Value Report
of any Independent Financial Expert, except to keep it on file and available for
inspection  by the  Holders.  The  determination  as to Current  Market Value in
accordance with the provisions of this Section 4.1(k) shall be conclusive on all
Persons.  The Independent  Financial Expert shall consult with management of the
Company in order to allow  management to comment on the proposed  value prior to
delivery to the Company of any Value Report.

            (l)  WHEN  NO  ADJUSTMENT  REQUIRED.   Without  limiting  any  other
exception  contained in this Section 4.1, and in addition thereto, no adjustment
need be made for:

            (i)   (A)  grants to,  exercises of Rights by, or issuances of
                  equity securities to employees, directors, consultants or
                  advisors of the Company or any of its subsidiaries and (B)
                  exercises of Rights by, or issuances of equity securities
                  in connection with Rights previously issued to former
                  employees, former directors, former consultants or former
                  advisors of KMC Telecom, Inc. (to the extent that all such
                  securities do not have an aggregate value in excess of 15%
                  of the equity value of the Company on a fully diluted
                  basis, as determined in good faith by the Board);

            (ii)  grants of options,  warrants or other  agreements or rights to
                  purchase  capital  stock of the Company  entered into prior to
                  the date of the  issuance of the  Warrants or any  issuance of
                  capital stock pursuant thereto or in connection therewith;

            (iii) rights to purchase  Common  Shares  pursuant to a Company plan
                  for the reinvestment of dividends or interest;

            (iv)  future  options,  warrants or other rights with an exercise or
                  conversion  price at least equal to the fair  market  value of
                  the related shares on the date of grant, as determined in good
                  faith by the Company's Board of Directors;

            (v)   a change in the par value of the Common  Shares  (including  a
                  change from par value to no par value or vice versa);

            (vi)  bona fide  public  offerings  or  private  placements  through
                  investment banks of national standing;

            (vii) the issuance of Warrants pursuant to Section 2.4 hereof; and

            (viii) the issuance of Warrants to pursuant to Section 2.5 hereof.

            To  the  extent  the  Warrants  become  convertible  into  cash,  no
adjustment need be made  thereafter as to the cash.  Interest will not accrue on
the cash.

          SECTION  4.2.  NOTICE OF  ADJUSTMENT.  Whenever  the  number of Common
Shares  purchasable  upon the exercise of each Warrant or the Exercise  Price is
adjusted, as herein provided, the Company shall cause, so far as it is able, the
Warrant Agent  promptly to mail,  at the expense of the Company,  to each Holder
notice of such  adjustment or adjustments and shall deliver to the Warrant Agent
a  certificate  of the  Auditors  setting  forth the  number  of  Common  Shares
purchasable  upon the exercise of each Warrant and the Exercise Price after such
adjustment,  setting  forth  a  brief  statement  of the  facts  requiring  such
adjustment and setting forth the  computation by which such adjustment was made.
Such  certificate  shall  be  conclusive  evidence  of the  correctness  of such
adjustment  except in the case of manifest  error.  The  Warrant  Agent shall be
entitled  to  rely  on  such   certificate   and  shall  be  under  no  duty  or
responsibility with respect to any such certificate, except to exhibit the same,
from  time  to  time,  to any  Holder  desiring  an  inspection  thereof  during
reasonable business hours upon reasonable notice. The Warrant Agent shall not at
any time be under any duty or responsibility to any Holders to determine whether
any facts exist which may require any  adjustment  of the Exercise  Price or the
number of Common  Shares  purchasable  on exercise of the Warrants or any of the
other  adjustments  set forth in Section  4.1, or with  respect to the nature or
extent of any such  adjustment when made, or with respect to the method employed
in making such  adjustment,  or the validity or value (or the kind or amount) of
any Common  Shares which may be  purchasable  on exercise of the  Warrants.  The
Warrant  Agent shall not be  responsible  for any failure of the Company to make
any cash  payment or to issue,  transfer or deliver  any Common  Shares or share
certificates upon the exercise of any Warrant.

            SECTION 4.3.  STATEMENT ON WARRANTS.  Irrespective of any adjustment
in the  Exercise  Price or the  number  or kind of shares  purchasable  upon the
exercise of the Warrants, Warrants theretofore or thereafter issued may continue
to  express  the same  price and  number and kind of shares as are stated in the
Warrants initially issuable pursuant to this Agreement.

            SECTION 4.4. NOTICE OF  CONSOLIDATION,  MERGER,  ETC. In case at any
time after the date  hereof  and prior to 5:00 p.m.  (New York City time) on the
Expiration  Date,  there shall be any (i)  consolidation or merger involving the
Company or sale,  transfer or other  disposition of all or substantially  all of
the  Company's  property,  assets  or  business  (except  (A) a merger  or other
reorganization  in which the  Company  shall be the  surviving  corporation  and
holders of Common Shares receive no consideration in respect of their shares and
(B) a merger of the Company into a wholly owned  subsidiary of the Company,  the
principal purpose of which, in the good faith  determination of the Board, is to


                                       18
<PAGE>

change the state of incorporation of the Company) or (ii) any other  transaction
contemplated by Section 4.1(j)(ii) above then, in any one or more of such cases,
the  Company  shall  cause to be mailed to the  Warrant  Agent and shall use its
reasonable  best  efforts  to cause  the  Warrant  Agent to mail,  at  Company's
expense, to each Holder of a Warrant, at the earliest  practicable time (and, in
any event,  not less than 20 days  before any date set for  definitive  action),
notice of the date on which such reorganization,  sale,  consolidation,  merger,
dissolution,  liquidation  or winding up shall take  place,  as the case may be.
Such notice shall also set forth such facts as shall indicate the effect of such
action (to the extent  such  effect may be known at the date of such  notice) on
the  Exercise  Price and the kind and  amount  of the  Common  Shares  and other
securities,  money and other property deliverable upon exercise of the Warrants.
Such notice shall also specify the date as of which the holders of record of the
Common  Shares or other  securities  or property  issuable  upon exercise of the
Warrants  shall be entitled to exchange  their shares for  securities,  money or
other  property  deliverable  upon  such  reorganization,  sale,  consolidation,
merger, dissolution, liquidation or winding up, as the case may be.


                                       19
<PAGE>

            SECTION 4.5. FRACTIONAL INTERESTS. If more than one Warrant shall be
presented  for exercise in full at the same time by the same Holder,  the number
of full Common Shares which shall be issuable  upon such exercise  thereof shall
be computed on the basis of the aggregate number of Common Shares purchasable on
exercise of the  Warrants  so  presented.  The Company  shall not be required to
issue fractional Common Shares upon the exercise of Warrants. If any fraction of
a Common Share would, except for the provisions of this Section 4.5, be issuable
on the exercise of any Warrant (or specified portion  thereof),  the Company may
pay an amount in cash  calculated  by it to be equal to the then Current  Market
Value per Common Share multiplied by such fraction computed to the nearest whole
cent.

            SECTION 4.6. WHEN  ISSUANCE OR PAYMENT MAY BE DEFERRED.  In any case
in which this Article IV shall require that an adjustment in the Exercise  Price
be made  effective  as of a record date for a specified  event,  the Company may
elect to defer until the  occurrence  of such event (i) issuing to the Holder of
any Warrant  exercised after such record date the Common Shares and other shares
in the capital of the Company,  if any,  issuable  upon such  exercise  over and
above the Common Shares and other shares in the capital of the Company,  if any,
issuable  upon such  exercise  and (ii) paying such Holder any amount in cash in
lieu of a fractional share; PROVIDED, HOWEVER, that the Company shall deliver to
such Holder a due bill or other appropriate  instrument evidencing such Holder's
right to receive such additional  Common Shares,  other shares and cash upon the
occurrence of the event requiring such adjustment.

            SECTION 4.7.  INITIAL PUBLIC OFFERING.  Notwithstanding  anything to
the  contrary  herein  contained,  if the  Company  conducts  an initial  public
offering of equity securities (other than nonconvertible  preferred shares), the
Company will give the Holders the  opportunity to convert (i) such Warrants into
warrants to purchase such equity securities (other than nonconvertible preferred
shares) and (ii) any Common Shares or other securities that have been previously
received  by the  Holders  upon  the  exercise  of  Warrants  into  such  equity
securities  (other  than  nonconvertible   preferred  shares).  Such  conversion
opportunity will be on terms and conditions determined to be fair and reasonable
by the Board.


                                    ARTICLE V

                           DECREASE IN EXERCISE PRICE

            The Board, in its sole discretion, shall have the right at any time,
or from time to time,  to decrease  the Exercise  Price of the  Warrants  and/or
increase the number of shares issuable upon the exercise of the Warrants.

                                   ARTICLE VI

                               LOSS OR MUTILATION

            Upon  receipt  by the  Company  and the  Warrant  Agent of  evidence
satisfactory  to them of the  ownership  and the  loss,  theft,  destruction  or
mutilation of any Warrant  Certificate and of indemnity or bond  satisfactory to
them and (in the case of mutilation)  upon surrender and  cancellation  thereof,
then,  in the  absence of notice to the  Company or the  Warrant  Agent that the
Warrants  represented  thereby have been acquired by a bona fide purchaser,  the
Company shall execute and the Warrant Agent shall countersign and deliver to the
registered  Holder  of  the  lost,   stolen,   destroyed  or  mutilated  Warrant
Certificate,  in exchange for or in lieu thereof,  a new Warrant  Certificate of
the same tenor and for a like aggregate number of Warrants. Upon the issuance of
any new Warrant  Certificate  under this Article VI, the Company may require the
payment of a sum sufficient to cover any tax or other  governmental  charge that
may be imposed in relation  thereto and other  expenses  (including the fees and
expenses  of the  Warrant  Agent) in  connection  therewith.  Every new  Warrant
Certificate  executed and  delivered  pursuant to this Article VI in lieu of any
lost,  stolen or destroyed  Warrant  Certificate  shall constitute a contractual
obligation of the Company whether or not the allegedly lost, stolen or destroyed
Warrant  Certificates  shall be at any time  enforceable  by anyone and shall be
entitled to the benefits of this Agreement equally and proportionately  with any
and all other Warrant  Certificates duly executed and delivered  hereunder.  The
provisions of this Article VI are  exclusive  and shall  preclude (to the extent
lawful)  all  other  rights or  remedies  with  respect  to the  replacement  of
mutilated, lost, stolen, or destroyed Warrant Certificates.


                                   ARTICLE VII

                          RESERVATION AND AUTHORIZATION
                                OF COMMON SHARES

            The  Company  shall at all times  reserve  and keep  available  such
number of its authorized but unissued Common Shares deliverable upon exercise of
the  Warrants  as will be  sufficient  to  permit  the  exercise  in full of all
outstanding  Warrants and will cause  appropriate  evidence of ownership of such
Common Shares to be delivered to the Warrant Agent upon its request for delivery
thereof  upon the exercise of Warrants.  The Company  covenants  that all Common
Shares of the Company that may be issued upon the exercise of the Warrants will,
upon issuance, be duly authorized, validly issued, fully paid and not subject to
any  calls for funds and free from  pre-emptive  rights  and all  taxes,  liens,
charges and security interests with respect to the issue thereof.

                                  ARTICLE VIII

               WARRANT TRANSFER BOOKS; RESTRICTIONS ON TRANSFER

            SECTION 8.1. TRANSFER AND EXCHANGE.  The Warrant  Certificates shall
be issued in registered  form only. The Warrant Agent shall keep at its office a
register for the registration of Warrant Certificates and transfers or exchanges
of  Warrant  Certificates  as  herein  provided  and other  appropriate  data as
determined by the Warrant Agent.  The Company shall,  upon reasonable  notice to
the Warrant  Agent,  have  access to such  register  during the Warrant  Agent's
regular business hours. All Warrant Certificates issued upon any registration of
transfer or exchange of Warrant  Certificates  shall be the valid obligations of
the Company, evidencing the same obligations,  and entitled to the same benefits
under  this  Agreement,  as  the  Warrant  Certificates   surrendered  for  such
registration of transfer or exchange.

            The  Warrants  (other  than any issued  pursuant  to Section  2.4 or
Section 2.5 hereof)  shall  initially  be issued as part of the  issuance of the
Units.  Prior to the  Separation  Date,  such Warrants may not be transferred or
exchanged  separately  from,  but may be  transferred or exchanged only together
with, the Series E Preferred Stock or the Series F Preferred  Stock, as the case
may be, issued as part of the respective  Unit. Any Warrants  issued pursuant to
Section  2.5  hereof  that are  initially  issued as part of a unit shall not be
transferred or exchanged  separately from the other  securities  comprising such
unit until the date of separation as described in such unit.

            A Holder may transfer its Warrants  only by written  application  to
the Warrant  Agent  stating the name of the proposed  transferee  and  otherwise
complying with the terms of this  Agreement.  No such transfer shall be effected
until,  and such  transferee  shall succeed to the rights of a Holder only upon,
final  acceptance and  registration  of the transfer by the Warrant Agent in the
register.  Prior to the  registration of any transfer of Warrants by a Holder as
provided herein, the Company, the Warrant Agent, and any agent of the Company or
the Warrant Agent may treat the Person in whose name the Warrants are registered
as the owner thereof for all purposes and as the Person entitled to exercise the
rights represented  thereby,  any notice to the contrary  notwithstanding.  When
Warrant  Certificates  are  presented  to the  Warrant  Agent  with a request to
register  the  transfer or to exchange  them for an equal  amount of Warrants of
other authorized  denominations,  the Warrant Agent shall register such transfer
or make such exchange as requested if its requirements for such transactions are
met. To permit  registrations  of transfers  and  exchanges,  the Company  shall
execute Warrant  Certificates at the Warrant Agent's request.  No service charge
shall be made for any registration of transfer or exchange of Warrants,  but the
Company  may  require  payment  of a sum  sufficient  to cover  any tax or other
governmental  charge that may be imposed in connection with any  registration of
transfer of Warrants.

            SECTION 8.2.  Intentionally Omitted.

            SECTION 8.3.  SPECIAL TRANSFER PROVISIONS.  The following
provisions shall apply:

            (a)  TRANSFERS TO QIBS.  The following  provisions  shall apply with
respect to the  registration of any proposed  transfer of Warrants to a QIB: the
Warrant Agent shall only register the transfer if such transfer is being made by
a  proposed  transferor  who has  checked  the box  provided  for on the form of
Warrant  Certificate  stating,  or has  otherwise  advised  the  Company and the
Warrant  Agent in writing,  that the sale has been made in  compliance  with the
provisions  of  Rule  144A to a  transferee  who has  signed  the  certification
provided  for on the  form of  Warrant  Certificate  stating,  or has  otherwise
advised the Company and the Warrant Agent in writing,  that it is purchasing the
Warrants  for its own account or an account  with  respect to which it exercises
sole investment  discretion and that it and any such account is a QIB within the
meaning of Rule 144A, and is aware that the sale to it is being made in reliance
on Rule 144A and acknowledges  that it has received such  information  regarding
the Company as it has requested  pursuant to Rule 144A or has  determined not to
request such  information  and that it is aware that the  transferor  is relying
upon  its  foregoing  representations  in  order to  claim  the  exemption  from
registration provided by Rule 144A.

            (b) TRANSFERS TO ANY OTHER PERSON.  The  following  provision  shall
apply with respect to the  registration of any proposed  transfer of Warrants to
any Person not specified in paragraph  (a) above  (including  any  Institutional
Accredited Investor which is not a QIB).

            (i) The  Warrant  Agent  shall  register  any  proposed  transfer of
      Warrants to any such Person only if (x) the  transferor  has  delivered to
      the Warrant Agent and the Company a certificate  substantially in the form
      of Exhibit  B-1 hereto  and, if required  by  paragraph  (d)  thereof,  an
      Opinion of Counsel to the effect set forth  therein  and (y) the  proposed
      transferee   has  delivered  to  the  Warrant  Agent  and  the  Company  a
      certificate substantially in the form of Exhibit B-2 hereto.

            (c) PRIVATE  PLACEMENT  LEGEND.  Upon the  registration of transfer,
exchange  or  replacement  of  Warrant  Certificates  not  bearing  the  Private
Placement Legend,  the Warrant Agent shall deliver Warrant  Certificates that do
not bear the  Private  Placement  Legend.  Upon the  registration  of  transfer,
exchange or replacement of Warrant  Certificates  bearing the Private  Placement
Legend, the Warrant Agent shall deliver only Warrant  Certificates that bear the
Private  Placement  Legend  unless there is  delivered  to the Warrant  Agent an
Opinion of Counsel reasonably  satisfactory to the Company,  its Counsel and the
Warrant   Agent  to  the  effect  that  neither  such  legend  nor  the  related
restrictions  on transfer are required in order to maintain  compliance with the
provisions of the Securities Act.

            (d) GENERAL.  (i) By its acceptance of any Warrants represented by a
Warrant  Certificate  bearing the Private Placement Legend,  each Holder of such
Warrants acknowledges the restrictions on transfer of such Warrants set forth in
this  Agreement  and in the  Private  Placement  Legend and agrees  that it will
transfer  such Warrants  only as provided in this  Agreement.  The Warrant Agent
shall not register a transfer of any Warrants unless such transfer complies with
the  restrictions on transfer of such Warrants set forth in this  Agreement.  In


                                       23
<PAGE>

connection  with any transfer of Warrants,  each Holder agrees by its acceptance
of Warrants to furnish the  Warrant  Agent or the Company  such  certifications,
legal opinions or other information as either of them may reasonably  require to
confirm that such  transfer is being made  pursuant to an exemption  from,  or a
transaction not subject to, the registration  requirements of the Securities Act
or any applicable laws of any state or foreign  jurisdiction;  PROVIDED that the
Warrant  Agent  shall  not  be  required  to  determine   (but  may  rely  on  a
determination  made by the Company with respect to) the  sufficiency of any such
certifications, legal opinions or other information.

                  (ii) The Warrant  Agent shall retain,  in accordance  with its
customary  procedure,   copies  of  all  letters,   notices  and  other  written
communications  received pursuant to Section 8.2 hereof or this Section 8.3. The
Company  shall have the right to inspect  and make  copies of all such  letters,
notices or other written  communications  at any reasonable time upon the giving
of reasonable written notice to the Warrant Agent.

            SECTION  8.4.  SURRENDER  OF  WARRANT   CERTIFICATES.   Any  Warrant
Certificate  surrendered for  registration of transfer,  exchange or exercise of
the Warrants  represented  thereby  shall,  if  surrendered  to the Company,  be
delivered to the Warrant Agent, and all Warrant  Certificates  surrendered or so
delivered to the Warrant Agent shall be promptly  cancelled by the Warrant Agent
and shall not be reissued by the Company and, except as provided in this Article
VIII in case of an exchange,  Article III hereof in case of the exercise of less
than all the Warrants  represented  thereby or Article VI in case of a mutilated
Warrant  Certificate,  no Warrant  Certificate shall be issued hereunder in lieu
thereof.  The Warrant  Agent shall  deliver to the Company  from time to time or
otherwise  dispose of such  cancelled  Warrant  Certificates  as the Company may
direct in writing.


                                   ARTICLE IX

                                 WARRANT HOLDERS

            SECTION 9.1.  WARRANT HOLDER DEEMED NOT A  SHAREHOLDER.  The Company
and the Warrant Agent may deem and treat the registered Holder(s) of the Warrant
Certificates as the absolute owner(s) thereof  (notwithstanding  any notation of
ownership  or other  writing  thereon  made by  anyone),  for the purpose of any
exercise  thereof  and for all other  purposes,  and neither the Company nor the
Warrant  Agent nor any agent  thereof  shall be  affected  by any  notice to the
contrary. Accordingly, the Company and/or the Warrant Agent shall not, except as
ordered by a court of  competent  jurisdiction  as  required by law, be bound to
recognize  any  equitable  or other claim to or interest in the  Warrants on the
part of any Person other than such  registered  Holder,  whether or not it shall
have  express  or other  notice  thereof.  Prior to the  valid  exercise  of the
Warrants, no Holder of a Warrant Certificate,  as such, shall be entitled to any
rights of a shareholder of the Company, including, without limitation, the right
to vote or to consent to any action of the shareholders, to receive dividends or
other  distributions,  to exercise any preemptive right or to receive any notice
of meetings of shareholders and, except as otherwise provided in this Agreement,


                                       24
<PAGE>

shall not be entitled to receive any notice of any proceedings of the Company.

            SECTION 9.2.  RIGHT OF ACTION.  All rights of action with respect to
this Agreement are vested in the Holders of the Warrants,  and any Holder of any
Warrant,  without the  consent of the Warrant  Agent or the Holders of any other
Warrant,  may, on such  Holder's  own behalf and for such  Holder's own benefit,
enforce,  and may institute and maintain any suit, action or proceeding  against
the Company suitable to enforce, or otherwise in respect of, such Holder's right
to  exercise  such  Warrants in the manner  provided in the Warrant  Certificate
representing such Warrants and in this Agreement.


                                    ARTICLE X

                                THE WARRANT AGENT

            SECTION  10.1.  DUTIES AND  LIABILITIES.  The Warrant  Agent  hereby
accepts the agency  established by this Agreement and agrees to perform the same
upon the terms and conditions  herein set forth, by all of which the Company and
the  Holders of  Warrants,  by their  acceptance  thereof,  shall be bound.  The
Warrant Agent shall not, by countersigning  Warrant Certificates or by any other
act  hereunder,  be deemed to make any  representations  as to the  validity  or
authorization  of the  Warrants  or the Warrant  Certificates  (except as to its
countersignature  thereon) or of any Common  Shares  issued upon exercise of any
Warrant,  or as to the accuracy of the  computation of the Exercise Price or the
number or kind or  amount of Common  Shares  deliverable  upon  exercise  of any
Warrant or the  correctness  of the  representations  of the Company made in the
certificates  that the Warrant  Agent  receives.  The Warrant Agent shall not be
accountable  for the use or  application  by the Company of the  proceeds of the
exercise of any Warrant.  The Warrant Agent shall not have any duty to calculate
or determine any  adjustments  with respect to either the Exercise  Price or the
kind and amount of Common  Shares  receivable  by Holders  upon the  exercise of
Warrants  required from time to time and the Warrant Agent shall have no duty or
responsibility  in determining the accuracy or correctness of such  calculation.
The Warrant  Agent shall not be (a) liable for any recital or  statement of fact
contained  herein  or in the  Warrant  Certificates  or for  any  action  taken,
suffered  or  omitted  by it in  good  faith  in the  belief  that  any  Warrant
Certificate  or any other  documents or any  signatures  are genuine or properly
authorized, (b) responsible for any failure on the part of the Company to comply
with any of its covenants and obligations  contained in this Agreement or in the
Warrant  Certificates  or (c) liable for any act or omission in connection  with
this  Agreement  except  for its own  gross  negligence,  bad  faith or  willful
misconduct.  The Warrant Agent is hereby authorized to accept  instructions with
respect to the  performance  of its duties  hereunder  from the  Chairman of the
Board, the Vice Chairman of the Board, the President,  Chief Executive  Officer,
the Chief Operating Officer, the Chief Financial Officer, or any other executive
officer of the Company and to apply to any such officer for instructions  (which
instructions  will be promptly given in writing when  requested) and the Warrant
Agent shall not be liable for any action  taken or suffered to be taken by it in
good faith in accordance with the  instructions  of any such officer;  PROVIDED,
HOWEVER, that, in its discretion, the Warrant Agent may, in lieu thereof, accept


                                       25
<PAGE>

other evidence of such or may require such further or additional  evidence as it
may deem reasonable.  The Warrant Agent shall not be liable for any action taken
with  respect  to any  matter in the  event it  requests  instructions  from the
Company  as to that  matter  and does not  receive  such  instructions  within a
reasonable period of time after the request therefor.

            The Warrant  Agent may execute  and  exercise  any of the rights and
powers hereby vested in it or perform any duty hereunder  either itself or by or
through its attorneys,  agents or employees,  and the Warrant Agent shall not be
answerable or  accountable  for any act,  default,  neglect or misconduct of any
such  attorneys,  agents or employees;  PROVIDED that  reasonable  care has been
exercised with respect to the retention of any such attorney, agent or employee.
The Warrant Agent shall not be under any obligation or duty to institute, appear
in or defend any action,  suit or legal  proceeding  in respect  hereof,  unless
first  indemnified  to its  reasonable  satisfaction.  The  Warrant  Agent shall
promptly  notify the  Company  in  writing of any claim made or action,  suit or
proceeding  instituted  against it  arising  out of or in  connection  with this
Agreement.

            The Company will perform, execute,  acknowledge and deliver or cause
to be  delivered  all such  further  acts,  instruments  and  assurances  as are
consistent  with this Agreement and as may reasonably be required by the Warrant
Agent in order to  enable it to carry  out or  perform  its  duties  under  this
Agreement.

            The  Warrant  Agent  shall  act  solely  as  agent  of  the  Company
hereunder.  The  Warrant  Agent  shall not be liable  except for the  failure to
perform  such  duties as are  specifically  set  forth  herein,  and no  implied
covenants or obligations  shall be read into this Agreement  against the Warrant
Agent,  whose duties and obligations  shall be determined  solely by the express
provisions hereof.

            SECTION 10.2. RIGHT TO CONSULT COUNSEL. The Warrant Agent may at any
time consult with legal counsel (who may be legal counsel for the Company),  and
the  written  opinion  or  advice  of such  counsel  shall be full and  complete
authorization  and  protection  to the Warrant Agent and the Warrant Agent shall
incur no  liability  or  responsibility  to the Company or to any Holder for any
action  taken,  suffered or omitted by it in good faith in  accordance  with the
opinion or advice of such counsel.

            SECTION  10.3.  COMPENSATION;  INDEMNIFICATION.  The Company  agrees
promptly  to pay the  Warrant  Agent from time to time and in any case within 30
days of receipt of an invoice,  compensation  for its services  hereunder as the
Company and the Warrant  Agent may agree from time to time,  and to reimburse it
upon  its  request  (which  shall  be   accompanied  by  reasonable   supporting
documentation)  for reasonable fees or expenses and reasonable  counsel fees and
expenses  incurred in connection with the execution and  administration  of this
Agreement,  and  further  agrees  to  indemnify  the  Warrant  Agent and save it
harmless against any losses,  liabilities or reasonable  expenses arising out of
or in connection  with the  acceptance  and  administration  of this  Agreement,


                                       26
<PAGE>

including,   without   limitation,   the   reasonable   costs  and  expenses  of
investigating or defending any claim of such liability,  except that the Company
shall have no liability hereunder to the extent that any such loss, liability or
expense  results  from the Warrant  Agent's own gross  negligence,  bad faith or
willful misconduct. The obligations of the Company under this Section 10.3 shall
survive the exercise and the expiration of the Warrants, the termination of this
Agreement  and the  resignation  or removal of the  Warrant  Agent in respect of
services or expenses incurred in connection with the Warrants or this Agreement.

            SECTION 10.4. NO RESTRICTIONS ON ACTIONS.  Nothing in this Agreement
shall be deemed to prevent  the  Warrant  Agent and any  shareholder,  director,
officer or employee of the Warrant Agent from buying,  selling or dealing in any
of the  Warrants or other  securities  of the  Company or  becoming  pecuniarily
interested  in  transactions  in  which  the  Company  may  be  interested,   or
contracting  with or lending  money to the Company or otherwise  acting as fully
and freely as though it were not the Warrant Agent under this Agreement. Nothing
herein shall  preclude the Warrant  Agent from acting in any other  capacity for
the Company or for any other legal entity.

            SECTION 10.5.  DISCHARGE OR REMOVAL;  REPLACEMENT WARRANT AGENT. The
Warrant  Agent may resign from its position as such and be  discharged  from all
further duties and liabilities  hereunder  (except liability arising as a result
of the Warrant Agent's own gross negligence,  bad faith or willful  misconduct),
after giving one month's prior written notice to the Company. The Company may at
any time remove the Warrant Agent upon one month's written notice specifying the
date  when such  discharge  shall  take  effect,  and the  Warrant  Agent  shall
thereupon in like manner be discharged  from all further duties and  liabilities
hereunder, except as aforesaid. The Warrant Agent shall mail to each Holder of a
Warrant,  at the  Company's  expense,  a copy of said notice of  resignation  or
notice of  removal,  as the case may be.  Upon such  resignation  or removal the
Company shall appoint in writing a new warrant agent.  If the Company shall fail
to make such  appointment  within a period of 30 days after it has been notified
in writing of such  resignation  by the  resigning  Warrant  Agent or after such
removal,  then the  resigning  or  removed  Warrant  Agent or the  Holder of any
Warrant may apply to any court of competent  jurisdiction for the appointment of
a new warrant agent.  After 30 days from receipt of, or giving,  notice,  as the
case may be, and pending  appointment  of a successor  to the  original  Warrant
Agent, either by the Company or by such a court, the duties of the Warrant Agent
shall be carried out by the Company. Any new warrant agent, whether appointed by
the Company or by such a court,  shall be a bank or trust company doing business
under the laws of the United States or any state  thereof,  in good standing and
having a combined capital and surplus of not less than $25,000,000. The combined
capital  and  surplus of any such new  warrant  agent  shall be deemed to be the
combined  capital and surplus as set forth in the most recent  annual  report of
its condition published by such warrant agent prior to its appointment, PROVIDED
that such  reports are  published  at least  annually  pursuant to law or to the
requirements  of a federal or state  supervising or examining  authority.  After
acceptance in writing of such  appointment by the new warrant agent, it shall be
vested with the same powers,  rights,  duties and  responsibilities as if it had
been  originally  named  herein  as  the  Warrant  Agent,  without  any  further
assurance, conveyance, act or deed; however, the original Warrant Agent shall in
all events  deliver and  transfer to the  successor  Warrant  Agent all property
(including, without limitation,  documents and recorded information), if any, at
the time held  hereunder by the original  Warrant Agent and if for any reason it
shall be necessary  or  expedient to execute and deliver any further  assurance,


                                       27
<PAGE>

conveyance,  act or deed,  the same shall be done at the  expense of the Company
and shall be legally and validly  executed  and  delivered  by the  resigning or
removed  Warrant  Agent.   Not  later  than  the  effective  date  of  any  such
appointment, the Company shall file notice thereof with the resigning or removed
Warrant  Agent and shall use its  reasonable  best efforts to forthwith  cause a
copy of such notice to be mailed by the  successor  Warrant Agent to each Holder
of a Warrant.  Failure to give any notice  provided  for in this  Section  10.5,
however, or any defect therein, shall not affect the legality or validity of the
resignation of the Warrant Agent or the  appointment of a new warrant agent,  as
the case may be. No  Warrant  Agent  hereunder  shall be liable  for any acts or
omissions of any successor Warrant Agent.

            SECTION 10.6.  SUCCESSOR  WARRANT AGENT.  Any corporation into which
the Warrant Agent or any new warrant  agent may be merged or  converted,  or any
corporation  resulting from any  consolidation to which the Warrant Agent or any
new  warrant  agent  shall be a party or any  corporation  succeeding  to all or
substantially all the corporate agency business of the Warrant Agent, shall be a
successor  Warrant Agent under this Agreement  without any further act, PROVIDED
that such  corporation  would be eligible  for  appointment  as successor to the
Warrant Agent under the  provisions of Section 10.5 hereof.  Any such  successor
Warrant Agent shall  promptly cause notice of its succession as Warrant Agent to
be mailed to each Holder of a Warrant.


                                   ARTICLE XI

                                  MISCELLANEOUS

            SECTION 11.1.  MONIES  DEPOSITED WITH THE WARRANT AGENT. The Warrant
Agent shall not be required to pay interest on any monies deposited  pursuant to
the provisions of this  Agreement  except such as it shall agree in writing with
the Company to pay thereon.  Any monies,  securities or other  property which at
any time shall be  deposited  by the  Company or on its behalf  with the Warrant
Agent pursuant to this Agreement shall be and are hereby  assigned,  transferred
and set over to the  Warrant  Agent in trust  for the  purpose  for  which  such
monies, securities or other property shall have been deposited; but such monies,
securities or other property need not be segregated from other funds, securities
or other property except to the extent  required by law. Any monies,  securities
or other property  deposited with the Warrant Agent for payment or  distribution
to the Holders  that remains  unclaimed  for one year after the date the monies,
securities  or other  property  was  deposited  with the Warrant  Agent shall be
delivered to the Company upon its request therefor.

            SECTION 11.2.  PAYMENT OF TAXES.  Subject to Article VI hereof,  all
Common Shares  issuable upon the exercise of Warrants  shall be validly  issued,
fully paid and not subject to any calls for funds, and the Company shall pay any
taxes and other  governmental  charges that may be imposed under the laws of the


                                       28
<PAGE>

United  States of  America  or any  political  subdivision  or taxing  authority
thereof or therein in respect of the issue or delivery  thereof upon exercise of
Warrants (other than income taxes imposed on the Holders). The Company shall not
be required,  however, to pay any tax or other charge imposed in connection with
any  transfer  involved  in the  issue  of any  certificate  for  Common  Shares
(including  other  securities  or  property  issuable  upon the  exercise of the
Warrants)  or payment  of cash to any Person  other than the Holder of a Warrant
Certificate  surrendered  upon the  exercise  of a  Warrant  and in case of such
transfer or payment,  the Warrant Agent and the Company shall not be required to
issue any share  certificate  or pay any cash  until such tax or charge has been
paid or it has  been  established  to the  Warrant  Agent's  and  the  Company's
satisfaction that no such tax or charge is due.

            SECTION  11.3.  NO  MERGER,  CONSOLIDATION  OR SALE OF ASSETS OF THE
COMPANY. Except as otherwise provided herein, the Company will not merge into or
consolidate with any other Person,  or sell or otherwise  transfer its property,
assets and business  substantially as an entirety to a successor of the Company,
unless the Person resulting from such merger or consolidation, or such successor
of the Company,  shall expressly assume, by supplemental  agreement satisfactory
in form to the Warrant  Agent and executed and  delivered to the Warrant  Agent,
the due and punctual  performance  and observance of each and every covenant and
condition of this  Agreement  or  contained in the Warrants to be performed  and
observed by the Company.

            SECTION  11.4.  REPORTS TO  HOLDERS.  Whether or not the  Company is
required to file reports with the  Commission,  the Company  shall file with the
Commission  all reports and other  information it would be required to file with
the  Commission  by Section  13(a) or 15(d)  under the  Exchange  Act if it were
subject  thereto.  The Company shall supply the Warrant Agent and each Holder or
shall supply to the Warrant Agent for  forwarding  to each such Holder,  without
cost to such Holder, copies of such reports and other information.  In addition,
at all times, upon the request of any Holder or any prospective purchaser of the
Warrants designated by a Holder, the Company shall supply to such Holder or such
prospective  purchaser  the  information  required  under  Rule  144A  under the
Securities Act.

            SECTION 11.5. NOTICES;  PAYMENT. (a) Except as otherwise provided in
Section  11.5(b)  hereof,  any  notice,  demand or delivery  authorized  by this
Agreement  shall be  sufficiently  given or made when  mailed,  if sent by first
class  mail,  postage  prepaid,  addressed  to any  Holder of a Warrant  at such
Holder's last known address appearing on the register of the Company  maintained
by the Warrant Agent and to the Company or the Warrant Agent as follows:

      THE COMMON SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE U.S.  SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
      OR ANY STATE SECURITIES LAWS, AND ACCORDINGLY,  MAY NOT BE OFFERED,  SOLD,
      PLEDGED  OR  OTHERWISE  TRANSFERRED  EXCEPT AS SET FORTH IN THE  FOLLOWING
      SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT
      IS A  "QUALIFIED  INSTITUTIONAL  BUYER" (AS DEFINED IN RULE 144A UNDER THE
      SECURITIES ACT) OR (B) IT IS AN  INSTITUTIONAL  "ACCREDITED  INVESTOR" (AS
      DEFINED  IN RULE  501(a)(1),  (2),  (3) OR (7) OF  REGULATION  D UNDER THE
      SECURITIES ACT) (AN "INSTITUTIONAL ACCREDITED INVESTOR"),  (2) AGREES THAT
      IT WILL NOT,  WITHIN THE TIME PERIOD  REFERRED  TO IN RULE 144(k)  (TAKING
      INTO ACCOUNT THE  PROVISIONS OF RULE 144(d) UNDER THE  SECURITIES  ACT, IF
      APPLICABLE),  AS IN  EFFECT  WITH  RESPECT  TO SUCH  TRANSFER,  RESELL  OR
      OTHERWISE  TRANSFER  THE COMMON  SHARES  REPRESENTED  BY THIS  CERTIFICATE
      EXCEPT (A) TO KMC TELECOM HOLDINGS, INC. (THE "COMPANY") OR ANY SUBSIDIARY
      THEREOF,  (B) TO A QUALIFIED  INSTITUTIONAL  BUYER IN COMPLIANCE WITH RULE
      144A UNDER THE SECURITIES ACT, (C) TO AN INSTITUTIONAL ACCREDITED INVESTOR
      THAT,  PRIOR  TO  SUCH  TRANSFER,  FURNISHES  TO THE  TRANSFER  AGENT  AND
      REGISTRAR  A  SIGNED  LETTER  CONTAINING   CERTAIN   REPRESENTATIONS   AND
      AGREEMENTS  RELATING TO THE  RESTRICTIONS ON TRANSFER OF THE COMMON SHARES
      REPRESENTED BY THIS  CERTIFICATE (THE FORM OF WHICH LETTER CAN BE OBTAINED
      FROM  THE  TRANSFER  AGENT  AND  REGISTRAR)  AND  AN  OPINION  OF  COUNSEL
      REASONABLY  ACCEPTABLE  TO THE COMPANY THAT SUCH TRANSFER IS IN COMPLIANCE
      WITH THE SECURITIES  ACT, (D) PURSUANT TO THE EXEMPTION FROM  REGISTRATION
      PROVIDED  BY RULE 144  UNDER  THE  SECURITIES  ACT (IF  AVAILABLE)  OR (E)
      PURSUANT TO AN EFFECTIVE  REGISTRATION  STATEMENT UNDER THE SECURITIES ACT

      AND (3)  AGREES  THAT IT WILL  DELIVER  TO EACH  PERSON TO WHOM THE COMMON
      SHARES   REPRESENTED  BY  THIS   CERTIFICATE   ARE  TRANSFERRED  A  NOTICE
      SUBSTANTIALLY  TO THE  EFFECT  OF THIS  LEGEND.  IN  CONNECTION  WITH  ANY
      TRANSFER OF THE COMMON SHARES  REPRESENTED BY THIS CERTIFICATE  WITHIN THE
      TIME PERIOD  REFERRED TO ABOVE,  THE HOLDER MUST CHECK THE APPROPRIATE BOX
      SET FORTH ON THE REVERSE  HEREOF  RELATING TO THE MANNER OF SUCH  TRANSFER
      AND SUBMIT THIS  CERTIFICATE TO THE TRANSFER  AGENT AND REGISTRAR.  IF THE
      PROPOSED TRANSFEREE IS AN INSTITUTIONAL  ACCREDITED  INVESTOR,  THE HOLDER
      MUST,  PRIOR TO SUCH  TRANSFER,  FURNISH TO EACH OF THE TRANSFER AGENT AND
      REGISTRAR  AND THE COMPANY SUCH  CERTIFICATIONS,  LEGAL  OPINIONS OR OTHER
      INFORMATION AS EITHER OF THEM MAY REASONABLY  REQUIRE TO CONFIRM THAT SUCH
      TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION  FROM, OR IN A TRANSACTION
      NOT SUBJECT TO, THE  REGISTRATION  REQUIREMENTS OF THE SECURITIES ACT. THE
      WARRANT  AGREEMENT  CONTAINS A PROVISION  REQUIRING THE TRANSFER AGENT AND
      REGISTRAR TO REFUSE TO REGISTER ANY TRANSFER OF THE SHARES OF COMMON STOCK
      REPRESENTED   BY  THIS   CERTIFICATE   IN  VIOLATION   OF  THE   FOREGOING
      RESTRICTIONS.

            SECTION 11.11. THIRD PARTY BENEFICIARIES. The Holders shall be third
party beneficiaries to the agreements made hereunder between the Company, on the
one hand, and the Warrant  Agent,  on the other hand, and each Holder shall have
the right to  enforce  such  agreements  directly  to the  extent it deems  such
enforcement  necessary  or  advisable  to  protect  its  rights or the rights of
Holders hereunder.  By acquiring Warrants, each Holder agrees to be bound by the
obligations of Holders generally as set forth herein and as such obligations may
be applicable to such Holder.

            SECTION 11.12.  TERMINATION.  Except as otherwise specified
herein, this Agreement shall terminate at 5:00 p.m. (New York City time) on
the Expiration Date.  Notwithstanding the foregoing, this Agreement shall
terminate on any earlier date as of which all Warrants have been exercised.

            SECTION 11.13.  GOVERNING LAW.  This Agreement shall be governed
by the laws of the State of New York.

                       WARRANTS TO PURCHASE COMMON SHARES

            This certifies that  ______________,  or its registered  assigns, is
the  owner of  ___________  Warrants,  each of  which  represents  the  right to
purchase  from  KMC  TELECOM  HOLDINGS,   INC.,  a  Delaware   corporation  (the
"Company"),  0.471756 shares of the Common Stock,  par value $0.01 per share, of
the Company (the "COMMON SHARES") at an exercise price (the "EXERCISE Price") of
$0.01 per Common  Share  (subject  to  adjustment  as  provided  in the  Warrant
Agreement hereinafter referred to below), upon surrender hereof at the office of
The Chase  Manhattan  Bank, or to its successor,  as the warrant agent under the
Warrant  Agreement  (any such  warrant  agent being  herein  called the "WARRANT
AGENT"),  with the Subscription  Form on the reverse hereof duly executed,  with
signature  guaranteed as therein  specified and simultaneous  payment in full by
wire transfer,  in cash or by certified or official bank or bank cashier's check
payable  to the order of the  Company.  Notwithstanding  the  foregoing,  if the
Common Shares (or other  securities)  issuable upon exercise of the Warrants are
registered   under  the  Exchange  Act,  the  Exercise  Price  may  be  paid  by
surrendering additional Warrants to the Warrant Agent having an aggregate Spread
equal to the aggregate  Exercise Price of the Warrants being  exercised.  At any
time  beginning one year after the Closing Date and on or before the  Expiration
Date, any  outstanding  Warrants may be exercised on any Business Day;  PROVIDED
that the Warrant Registration  Statement is, at the time of exercise,  effective
and  available  for the exercise of Warrants or the exercise of such Warrants is
exempt from the registration requirements of the Securities Act.

            This Warrant  Certificate  is issued under and in accordance  with a
Warrant Agreement dated as of February 4, 1999 (the "WARRANT AGREEMENT"),  among
The Chase Manhattan  Bank, as Warrant Agent,  the Company,  Newcourt  Commercial
Finance  Corporation,  Lucent Technologies Inc. and any Additional Purchaser (as
described  therein)  and a Warrant  Registration  Rights  Agreement  dated as of
February  4, 1999  (the  "WARRANT  REGISTRATION  RIGHTS  AGREEMENT"),  among the
Company, Newcourt Commercial Finance Corporation,  Lucent Technologies Inc., and
any Additional  Purchaser and is subject to the Certificate of Incorporation and
Bylaws of the Company and to the terms and provisions  contained therein, to all
of which terms and provisions the Holder of this Warrant Certificate consents by
acceptance   hereof.  The  terms  of  the  Warrant  Agreement  and  the  Warrant
Registration  Rights Agreement are hereby  incorporated  herein by reference and
made a part hereof.  Reference is hereby made to the Warrant  Agreement  and the
Warrant  Registration  Rights  Agreement for a full  description  of the rights,


                                       34
<PAGE>

limitations  of rights,  obligations,  duties and  immunities  thereunder of the
Company and the Holders of the Warrants. The summary of the terms of the Warrant
Agreement  and the  Warrant  Registration  Rights  Agreement  contained  in this
Warrant  Certificate  is qualified  in its entirety by express  reference to the
Warrant Agreement and the Warrant Registration Rights Agreement.  All terms used
in this Warrant  Certificate  that are defined in the Warrant  Agreement and the
Warrant  Registration  Rights Agreement shall have the meanings assigned to them
in such agreements.

            Copies of the Warrant Agreement and the Warrant  Registration Rights
Agreement  are on file at the office of the Warrant Agent and may be obtained by
writing to the Warrant Agent at the following address:

            The Chase Manhattan Bank

            New York, NY  10001-2697
            Attention:  Capital Markets Fiduciary Services

            If the Company merges or consolidates  with or into, or sells all or
substantially  all of its  property  and  assets  to,  another  Person  and  the
consideration  received by holders of Common Shares consists solely of cash, the
Holders of Warrants  shall be entitled to receive  distributions  on the date of
such event on an equal basis with holders of Common Shares (or other  securities
issuable upon  exercise of the  Warrants) as if the Warrants had been  exercised
immediately prior to such event (less the Exercise Price).  Upon receipt of such
payment,  if any,  the  rights of a Holder  shall  terminate  and cease and such
Holder's Warrants shall expire.

            The number of Common  Shares  purchasable  upon the exercise of each
Warrant  and the price per share are  subject to  adjustment  as provided in the
Warrant Agreement.  Except as stated in the immediately preceding paragraph,  in
the event the Company merges or consolidates with, or sells all or substantially
all of its assets to, another Person, each Warrant will, upon exercise,  entitle
the Holder  thereof to  receive  the number of shares of capital  stock or other
securities  or the  amount  of money and other  property  which the  holder of a
Common  Share (or other  securities  or  property  issuable  upon  exercise of a
Warrant) is entitled to receive upon completion of such merger, consolidation or
sale.

            As to any final  fraction of a share which the same Holder of one or
more Warrant  Certificates would otherwise be entitled to purchase upon exercise
thereof in the same  transaction,  the  Company  may pay the cash value  thereof
determined as provided in the Warrant Agreement.

            Subject to Article VI of the Warrant  Agreement,  all Common  Shares
issuable by the Company upon the exercise of Warrants  shall be validly  issued,
fully paid and not subject to any calls for funds, and the Company shall pay any
taxes and other  governmental  charges that may be imposed under the laws of the


                                       35
<PAGE>

United  States of  America  or any  political  subdivision  or taxing  authority
thereof or therein in respect of the issue or delivery  thereof upon exercise of
Warrants (other than income taxes imposed on the Holders). The Company shall not
be required,  however, to pay any tax or other charge imposed in connection with
any  transfer  involved  in the  issue  of any  certificate  for  Common  Shares
(including  other  securities  or  property  issuable  upon the  exercise of the
Warrants)  or payment  of cash to any Person  other than the Holder of a Warrant
Certificate  surrendered  upon the  exercise  of a  Warrant  and in case of such
transfer or payment,  the Warrant Agent and the Company shall not be required to
issue any share  certificate  or pay any cash  until such tax or charge has been
paid or it has  been  established  to the  Warrant  Agent's  and  the  Company's
satisfaction that no such tax or charge is due.

            Subject to the  restrictions on and conditions to transfer set forth
in Articles II and VIII of the Warrant Agreement,  this Warrant  Certificate and
all rights hereunder are transferable by the registered  Holder hereof, in whole
or in part,  on the register of the Company  maintained by the Warrant Agent for
such purpose at the Warrant Agent's office in New York, New York, upon surrender
of  this  Warrant  Certificate  duly  endorsed,  or  accompanied  by  a  written
instrument of transfer in form satisfactory to the Company and the Warrant Agent
duly executed,  with signatures  guaranteed as specified in the attached Form of
Assignment,  by the registered  Holder hereof or his attorney duly authorized in
writing  and by  such  other  documentation  required  pursuant  to the  Warrant
Agreement and upon payment of any necessary  transfer tax or other  governmental
charge imposed upon such transfer.  Upon any partial transfer,  the Company will
sign and issue and the Warrant Agent will countersign and deliver to such Holder
a new Warrant  Certificate  or  Certificates  with respect to any portion not so
transferred.  Each taker and Holder of this Warrant  Certificate,  by taking and
holding the same, consents and agrees that prior to the registration of transfer
as  provided  in the Warrant  Agreement,  the Company and the Warrant  Agent may
treat the Person in whose name the Warrants are registered as the absolute owner
hereof  for any  purpose  and as the  Person  entitled  to  exercise  the rights
represented hereby, any notice to the contrary notwithstanding. Accordingly, the
Company  and/or the  Warrant  Agent  shall not,  except as ordered by a court of
competent  jurisdiction  as required by law, be bound to recognize any equitable
or other claim to or interest  in the  Warrants on the part of any Person  other
than such  registered  Holder,  whether  or not it shall  have  express or other
notice thereof.

            This  Warrant  Certificate  may be  exchanged  at the  office of the
Warrant  Agent  maintained  for such  purpose in New York,  New York for Warrant
Certificates  representing  the same  aggregate  number  of  Warrants,  each new
Warrant  Certificate  to represent  such number of Warrants as the Holder hereof
shall designate at the time of such exchange.

            Prior to the valid exercise of the Warrants  represented hereby, the
Holder of this Warrant Certificate, as such, shall not be entitled to any rights
of a shareholder of the Company,  including,  without  limitation,  the right to
vote  or  to  consent  to  any  action  of  the  shareholders,  to  receive  any
distributions,  to exercise  any  pre-emptive  right or to receive any notice of
meetings of shareholders, and shall not be entitled to receive any notice of any
proceedings of the Company except as provided in the Warrant Agreement.

hereby  shall  cease on  February  1,  2009,  unless  sooner  terminated  by the
liquidation,  dissolution or winding-up of the Company or as otherwise  provided
in the Warrant  Agreement upon the  consolidation or merger of the Company with,
or sale of the  Company  to,  another  Person or unless such date is extended as
provided in the Warrant Agreement.

Re:  Warrants (the "WARRANTS") to Purchase
     Common Shares of
     KMC Telecom Holdings, Inc. (the "COMPANY")


Ladies and Gentlemen:

           In connection  with our proposed  purchase of  ___________  aggregate
number of Warrants, we confirm that:

           1. We understand  that any subsequent  transfer of the Warrants,  any
     interest therein or the Common Shares issuable upon exercise of any Warrant
     (the "WARRANT  SHARES") is subject to certain  restrictions  and conditions
     set forth in the Warrant Agreement dated as of February 4, 1999 relating to
     the Warrants (the "WARRANT  AGREEMENT") and the Warrant Registration Rights
     Agreement  dated  February 4, 1999  relating to the Warrants  (the "WARRANT
     REGISTRATION  RIGHTS AGREEMENT") and the undersigned agrees to be bound by,
     and not to resell,  pledge or  otherwise  transfer  the Warrants or Warrant
     Shares except in compliance with, such  restrictions and conditions and the
     U.S. Securities Act of 1933, as amended (the "SECURITIES ACT").

           2. We  understand  that  the  Warrants  represented  by this  Warrant
     Certificate  and, as of the date this Warrant  Certificate  was  originally


                                       44
<PAGE>

     issued,  the Warrant Shares have not been  registered  under the Securities
     Act,  and  accordingly  may not be  offered,  sold,  pledged  or  otherwise
     transferred except as set forth in the following sentence. We agree that we
     will  not,  within  the  time  period  referred  to in Rule  144(k)  of the
     Securities Act (taking into account the provisions of Rule 144(d) under the
     Securities Act, if applicable) under the Securities Act as in effect on the
     date of the  transfer of this  Warrant,  resell or  otherwise  transfer the
     Warrants  represented by this Warrant Certificate except (a) to KMC Telecom
     Holdings,  Inc. or any subsidiary thereof, (b) to a qualified institutional
     buyer in compliance  with Rule 144A under the Securities  Act, (c) pursuant
     to  the  exemption  from  registration  provided  by  Rule  144  under  the
     Securities Act (if available),  (d) to an institutional accredited investor
     that, prior to such transfer,  furnishes to you, to the Company and, in the
     case of the Warrant Shares, to the transfer agent and registrar therefor, a
     signed letter containing certain representations and agreements relating to
     the  restrictions  on transfer of the Warrants  represented by this Warrant
     Certificate  (the form of which  letter can be  obtained  from the  Warrant
     Agent) and an opinion of counsel  acceptable to KMC Telecom Holdings,  Inc.
     and its counsel that such transfer is in compliance with the Securities Act
     or (f) pursuant to an effective registration statement under the Securities
     Act and, in each case, in accordance with applicable state securities laws.

           3. We understand  that, on any proposed  resale of any Warrants,  any
     interest  therein or Warrant Shares,  we will be required to furnish to you
     and the Company such  certifications,  legal opinions and other information
     as you and the Company may reasonably  require to confirm that the proposed
     sale complies with the foregoing  restrictions.  We further understand that
     the Warrants purchased by us will bear a legend to the foregoing effect.

           4. We are an institutional  "accredited investor" (as defined in Rule
     501(a)(1),  (2), (3) or (7) of Regulation D under the  Securities  Act) and
     have such knowledge and experience in financial and business  matters as to
     be capable of  evaluating  the  merits and risks of our  investment  in the
     Warrants,  and we and any accounts for which we are acting are each able to
     bear the economic risk of our or its investment for an indefinite period of
     time.

           5. We are acquiring the Warrants  purchased by us for our own account
     or for one or more accounts (each of which is an institutional  "accredited
     investor") as to each of which we exercise sole investment discretion.

            2.    PIGGY-BACK REGISTRATION RIGHTS.

             (a) If, prior to the Expiration  Date, the Company proposes to file
a  Registration  Statement  with the  Commission  respecting  an offering of any
shares  of Common  Stock (or other  securities  issuable  upon  exercise  of the
Warrants)  (other than (i) an offering  registered  solely on Form S-4 or S-8 or
any successor  form thereto,  or (ii) the initial  public  offering of shares of
Common Stock (or other securities  issuable upon exercise of the Warrants) if no
shareholder of the Company participates  therein), the Company shall give prompt
written  notice to all the Holders of  Warrants  or Common  Shares or such other
securities received upon exercise of Warrants,  to the extent such Common Shares
or other securities would be (upon issuance) or are, as the case may be, subject
to restrictions on transfer, at least 30 days prior to the initial filing of the
registration statement relating to such offering (the "REGISTRATION STATEMENT").
Each such  Holder  shall have the right,  within 20 days after  delivery of such
notice,  to request in writing that the Company include all or a portion of such
of the Common Shares  issuable upon  exercise of such  Holder's  Warrants,  such
other securities as shall be issuable upon the exercise of the Warrants,  or the
Common  Shares or such other  securities  received  upon the  exercise  thereof,
pursuant to the Warrant  Agreement,  in each case to the extent that such Common
Shares or other  securities would be (upon issuance) or are, as the case may be,
subject to restrictions  on transfer,  ("WARRANT  SHARES") in such  Registration
Statement  ("PIGGY-BACK  REGISTRATION RIGHTS"). The Company shall include in the
public  offering  all of the  Warrant  Shares  that a Holder  has  requested  be
included,  unless the  underwriter  for the public  offering or the  underwriter
managing  the public  offering  (in either  case,  the  "MANAGING  UNDERWRITER")
delivers a notice (a "CUTBACK  NOTICE") pursuant to Section 2(b) or 2(c) hereof.
The managing  underwriter  may deliver one or more  Cutback  Notices at any time
prior to the execution of the underwriting agreement for the public offering.

            (b) If a proposed  public  offering  includes both  securities to be
offered for the account of the Company  ("COMPANY  IPO SHARES") and shares to be
sold by stockholders, the provisions of this Section 2(b) shall be applicable if
the managing underwriter delivers a Cutback Notice stating that, in its opinion,
the number of Common Shares (other than (a) Existing  Warrant  Shares to be sold
by any Existing  Holders and (b) Warrant  Shares to be sold by any Holders) that
selling  stockholders  propose  to sell  therein,  whether  or not such  selling
stockholders  have the right to include shares therein (the "OTHER IPO SHARES"),
plus the number of  Existing  Warrant  Shares  that the  Existing  Holders  have
requested to be sold therein, plus the number of Warrant Shares that the Holders
have  requested  to be sold  therein,  plus the Company IPO Shares,  exceeds the
maximum number of shares  specified by the managing  underwriter in such Cutback
Notice that may be distributed  without adversely affecting the price, timing or
distribution  of the Company IPO Shares.  Such maximum number of shares that may
be so sold, excluding the Company IPO Shares, are referred to as the "INCLUDIBLE
SHARES."

                                       5
<PAGE>

            If the managing  underwriter  delivers such Cutback Notice,  (i) the
Company shall be entitled to include all of the Company IPO Shares in the public
offering,  (ii) each  stockholder  who has  requested the inclusion of Other IPO
Shares in the public offering pursuant to Section 6.1 or 6.2 of the Stockholders
Agreement  shall be  entitled  to  include  all of its Other IPO Shares and each
Existing  Holder who has requested the inclusion of its Existing  Warrant Shares
shall be entitled to include all of its Existing  Warrant Shares,  in each case,
in priority to the inclusion of any Warrant  Shares  requested to be included by
Holders and (iii) except as  otherwise  provided in the  preceding  clause (ii),
each requesting Holder shall be entitled to include in the public offering up to
its pro rata  portion of the  Includible  Shares in  priority  to the  inclusion
(except as  otherwise  provided in the  preceding  clause (ii)) of any Other IPO
Shares that are proposed to be sold in such public offering.

            (c) If a proposed public offering is entirely a secondary  offering,
the  provisions  of this  Section  2(c)  shall  be  applicable  if the  managing
underwriter  delivers  a  Cutback  Notice  stating  that,  in its  opinion,  the
aggregate number of Existing Warrant Shares, Warrant Shares and Other IPO Shares
proposed  to  be  sold  therein  exceeds  the  maximum  number  of  shares  (the
"INCLUDIBLE  SECONDARY  SHARES")  specified by the managing  underwriter in such
Cutback Notice that may be distributed  without  adversely  affecting the price,
timing or distribution of the Common Shares being  distributed.  If the managing
underwriter delivers such Cutback Notice, (i) each stockholder who has requested
the inclusion of Other IPO Shares in the public offering pursuant to Section 6.1
or 6.2 of the  Stockholders  Agreement  shall be  entitled to include all of its
Other IPO Shares and each Existing Holder who has requested the inclusion of its
Existing Warrant Shares shall be entitled to include all of its Existing Warrant
Shares,  in each case,  in  priority  to the  inclusion  of any  Warrant  Shares
requested to be included by Holders and (ii) except as otherwise provided in the
preceding clause (i), each requesting Holder shall be entitled to include in the
public offering up to its pro rata portion of the Includible Secondary Shares in
priority to the inclusion  (except as set forth in the preceding  clause (i)) of
any Other IPO Shares that are proposed to be sold in such public offering.

            (d) The  underwriting  agreement  for  such  public  offering  shall
provide  that each  requesting  Holder  shall have the right to sell its Warrant
Shares (other than Warrant Shares excluded from such public offering pursuant to
a Cutback Notice and the terms of Section 2(b) or 2(c)) to the  underwriters and
that the underwriters shall purchase the Warrant Shares at the price paid by the
underwriters  for the Common  Shares sold by the Company  and/or  other  selling
stockholders, as the case may be.

            3.    SHELF REGISTRATION.

            (a) If only the Company  sells  Common  Shares in an initial  public
offering or all of the Warrant  Shares have not been sold in a public  offering,
the Company shall use its reasonable  best efforts to cause to be filed pursuant
to Rule 415 under  the  Securities  Act a shelf  registration  statement  on the


                                       6
<PAGE>

appropriate form (the "WARRANT REGISTRATION STATEMENT") covering the issuance of
the Warrant  Shares upon  exercise of the Warrants and shall use its  reasonable
best efforts to cause the Warrant  Registration  Statement  to become  effective
under the  Securities  Act within 180 days after the closing date of the initial
public  offering;  PROVIDED,  HOWEVER,  that  (1) in no  event  may the  Warrant
Registration  Statement be declared  effective prior to the first anniversary of
the  Closing  Date and (2) if the  Commission  shall  request  that the  Company
register the resale of the Warrant Shares instead of the issuance  thereof,  the
Warrant  Registration  Statement  shall  register such resale as opposed to such
issuance.  The Company  shall use  reasonable  best  efforts to keep the Warrant
Registration Statement continuously effective until the earlier of (i) such time
as all Warrants have been  exercised  or, in the case of clause (2),  until such
time as all Warrant Shares have been resold or (ii) the Expiration  Date.  Prior
to filing the Warrant  Registration  Statement  or any  amendment  thereto,  the
Company shall provide a copy thereof to the Purchaser and its counsel and afford
them a reasonable time to comment thereon.

            If the Company is unable to file or cause to be filed,  or is unable
to   maintain   the   effectiveness   of  a  Warrant   Registration   Statement,
notwithstanding  its  reasonable  best efforts to do so, the Company shall cause
such filing to take place, or shall cause such Warrant Registration Statement to
again become  effective,  after removal of the impediment to file or to maintain
the effectiveness of such Warrant Registration Statement.

            (b) If the Warrant Registration  Statement shall register the resale
of the Warrant Shares (a "RESALE  SHELF") as provided in Section  3(a)(2) above,
the Company agrees to:

            (i) make available for inspection by representatives of the Holders,
      any underwriter  participating in any disposition  pursuant to such Resale
      Shelf  and  attorneys  and  accountants  designated  by  the  Holders,  at
      reasonable times and in a reasonable manner,  financial and other records,
      documents and  properties of the Company that are pertinent to the conduct
      of due diligence  customary for an  underwritten  offering,  and cause the
      officers, directors and employees of the Company to supply all information
      reasonably requested by any such representative,  underwriter, attorney or
      accountant in connection with a Resale Shelf; PROVIDED, HOWEVER, that such
      persons  shall  first  agree  in  writing  with  the  Company  to use such
      information  only in  connection  with  the  transaction  for  which  such
      information was obtained and that any  information  that is reasonably and
      in good faith  designated by the Company in writing as confidential at the
      time of delivery of such  information  shall be kept  confidential by such
      persons,  unless and to the extent that disclosure of such  information is
      required by law or such  information  becomes  generally  available to the
      public other than as a result of a disclosure or failure to safeguard such
      information by such person;

            (ii) use its  reasonable  best  efforts to cause all Warrant  Shares
      sold under a Resale Shelf to be listed on any  securities  exchange or any


                                       7
<PAGE>

      automated quotation system on which securities of the same class issued by
      the Company are then listed if requested by the Holders of Warrant  Shares
      representing a majority of the Warrants  originally  issued, to the extent
      such Warrant Shares satisfy applicable listing requirements;

            (iii) provide as soon as practicable,  a reasonable number of copies
      of the Warrant Registration Statement, any pre-effective or post-effective
      amendment  thereto,   and  the  prospectus   (including  each  preliminary
      prospectus  and any  amendment or  supplements  thereto)  included in such
      Resale Shelf to Holders that are selling  Warrant Shares  pursuant to such
      Resale Shelf;

            (iv) cause to be  provided to the  Warrant  Agent,  on behalf of the
      Holders and beneficial owners of Warrant Shares, upon the effectiveness of
      such Resale Shelf, a customary "10b-5" opinion of independent  counsel (an
      "OPINION") and a customary "cold comfort"  letter of independent  auditors
      (a "COMFORT LETTER");

            (v) cause to be provided to Holders and beneficial owners of Warrant
      Shares an Opinion  and Comfort  Letter with  respect to each Form 10-K and
      Form 10-Q,  including any  amendments  thereto,  that is  incorporated  by
      reference in such Resale Shelf; and

            (vi) notify the Warrant Agent, for distribution to the Holders,  (A)
      when the Resale  Shelf has become  effective  and when any  post-effective
      amendment thereto has been filed and becomes effective, (B) of any request
      by the  Commission or any state  securities  authority for  amendments and
      supplements  to  the  Resale  Shelf  or of  any  material  request  by the
      Commission or any state  securities  authority for additional  information
      after the Resale  Shelf has become  effective,  (C) of the issuance by the
      Commission or any state securities  authority of any stop order suspending
      the effectiveness of the Resale Shelf or the initiation of any proceedings
      for that purpose,  (D) if,  between the effective date of the Resale Shelf
      and the  closing  of any  sale of  Warrant  Shares  covered  thereby,  the
      representations   and   warranties   of  the  Company   contained  in  any
      underwriting  agreement,  securities  sales  agreement  or  other  similar
      agreement,  including this Agreement,  relating to disclosure  cease to be
      true and correct in any  material  respect or if the Company  receives any
      notification  with respect to the suspension of the  qualification  of the
      Warrant  Shares  for sale in any  jurisdiction  or the  initiation  of any
      proceeding for such purpose,  (E) of the happening of any event during the
      period the Resale  Shelf is  effective  such that such Resale Shelf or the
      related  prospectus  contains an untrue  statement  of a material  fact or
      omits to state a material fact required to be stated  therein or necessary
      to make statements  therein not misleading and (F) of any determination by
      the Company that a  post-effective  amendment to a Registration  Statement
      would be  appropriate.  The Holders hereby agree to suspend the use of the
      prospectus contained in any Resale Shelf upon receipt of such notice under


                                       8
<PAGE>

      clause (C), (E) or (F) above until,  in the case of clause (C),  such stop
      order is removed or rescinded  or, in the case of clauses (E) and (F), the
      Company  has  amended or  supplemented  such  prospectus  to correct  such
      misstatement or omission.

            4.    SUSPENSION.

            Notwithstanding  the  foregoing,   in  addition  to  any  suspension
contemplated  by  clauses  (C),  (E) or  (F) of  Section  3(b)(vi),  during  any
consecutive  365-day  period,  the Company  shall have the  privilege to suspend
availability of the Warrant  Registration  Statement and the related  prospectus
for (i) up to two 30-consecutive-day periods, except for the 30 days immediately
prior to the Expiration  Date, if the Board  determines in good faith that there
is a valid purpose for such suspension and (ii) five additional, non-consecutive
three-day  periods,  except for the 30 days immediately  prior to the Expiration
Date,  if the Board  determines  in good faith that the Company  cannot  provide
adequate disclosure during such period due to circumstances  beyond its control.
Notice of such suspension shall be given promptly to the Warrant Agent.

            5.    BLUE SKY.

            The Company  shall use its  reasonable  best  efforts to register or
qualify the Underlying  Securities proposed to be sold or issued pursuant to the
Registration   Statement  or  the  Warrant  Registration   Statement  under  all
applicable  securities  or "blue  sky" laws of all  jurisdictions  in the United
States  in which  any  Holder  of  Warrants  may or may be  deemed  to  purchase
Underlying  Securities  upon the  exercise  of Warrants or resale of the Warrant
Shares,  as the case may be,  and  shall  use its  reasonable  best  efforts  to
maintain such  registration or  qualification  through the earlier of (A) in the
case of a Registration Statement,  the date upon which all of the Warrant Shares
have been sold or such other sale as shall be required by  applicable  law,  (B)
the date upon which all Warrants have been  exercised or all Warrant Shares have
been resold, as the case may be, under the Warrant Shelf Registration  Statement
and (C) the Expiration Date;  PROVIDED,  HOWEVER,  that the Company shall not be
required to (i) qualify as a foreign  corporation  or as a broker or a dealer in
securities  in any  jurisdiction  where it would not  otherwise  be  required to
qualify  but for this  Section  5, (ii) file any  general  consent to service of
process or (iii)  subject  itself to taxation in any  jurisdiction  if it is not
otherwise so subject.

            6.    ACCURACY OF DISCLOSURE.

            The Company  (and its  successors)  represents  and warrants to each
Holder (and each beneficial  owner of a Warrant or Warrant Share) and agrees for
the benefit of each Holder  (and each  beneficial  owner of a Warrant or Warrant
Share) that,  except during any period in which the  availability of the Warrant
Registration  Statement  has  been  suspended,   (i)  the  Warrant  Registration


                                       9
<PAGE>

Statement and the documents  incorporated by reference  therein will not contain
any  untrue  statement  of a  material  fact or omit to  state a  material  fact
necessary to make the statements therein not misleading; and (ii) the prospectus
delivered to such Holder upon its exercise of Warrants or pursuant to which such
Holder  sells  its  Warrant  Shares,  as the  case  may be,  and  the  documents
incorporated  by reference  therein  will not contain any untrue  statement of a
material fact or omit to state a material fact  necessary to make the statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading;  PROVIDED, HOWEVER, that representations,  warranties and agreements
set forth in this  Section  6 do not apply to  statements  or  omissions  in the
Warrant  Registration  Statement or any such prospectus  based upon  information
relating to any Holder  furnished to the Company (or its  successors) in writing
by such Holder expressly for use therein.

            7.    INDEMNITY.

            The Company  hereby agrees to indemnify each  beneficial  owner of a
Warrant and each person,  if any, who controls any beneficial owner of a Warrant
within the meaning of either  Section 15 of the  Securities Act or Section 20 of
the Exchange Act, or is under common  control  with,  or is  controlled  by, any
beneficial  owner of a Warrant  (whether or not it is, at the time the indemnity
provided for in this Section 7 is sought,  such a  beneficial  owner),  from and
against all losses,  damages or liabilities  which such beneficial  owner or any
such controlling or affiliated  person suffers as a result of any breach, on the
date of any exercise of a Warrant by such beneficial  owner or the resale of any
Warrant  Share  by  such  Holder,   in  either  case  pursuant  to  the  Warrant
Registration  Statement,  of  the  representations,   warranties  or  agreements
contained in Section 6 hereof.  Each  beneficial  owner of a Warrant  Share sold
pursuant to a Resale Shelf, by accepting its beneficial  ownership of a Warrant,
hereby (i) agrees to provide the Company  with  information  with  respect to it
that the Company  reasonably  requests in  connection  with any Resale Shelf and
(ii) agrees,  severally and not jointly, to indemnify the Company, its directors
and  officers and each  person,  if any,  who  controls  the Company  within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act against any liability  incurred by it or such controlling person as a result
of any  misstatement  of information  provided by such  beneficial  owner to the
Company in writing  expressly  for inclusion in the Resale Shelf or any omission
of a material fact from any such  information  provided by such beneficial owner
to the Company.

            8.    EXPENSES.

            All expenses incident to the Company's  performance of or compliance
with  its  obligations  under  this  Agreement  will be  borne  by the  Company,
regardless of whether a Registration Statement or Warrant Registration Statement
becomes  effective,  including without limitation (i) all Commission or National
Association of Securities Dealers,  Inc.  registration and filing fees, (ii) all
reasonable  fees and expenses  incurred in connection with compliance with state
securities  or "blue sky" laws,  (iii) all  reasonable  expenses  of any persons


                                       10
<PAGE>

incurred by or on behalf of the Company in preparing or assisting in  preparing,
word  processing,  printing and distributing  any  registration  statement,  any
prospectus,  any amendments or supplements  thereto and other documents relating
to the performance of and compliance  with this  Agreement,  (iv) the reasonable
fees (including  reasonable  legal fees and expenses) and  disbursements  of the
Warrant Agent,  (v) the  reasonable  fees and  disbursements  of counsel for the
Company  and (vi)  the fees and  disbursements,  if any,  of the  Auditors;  but
excluding  any and all fees,  expenses  and  disbursements  of the Holders  (not
specifically  included  above),  including,  without  limitation,  (x)  fees and
disbursements  of counsel  retained  by the  participating  Holders  and (y) the
Holder's share of underwriting discounts and commissions.

            9. COVENANTS OF THE COMPANY.

            The Company hereby agrees and covenants as follows:

            (a) After any initial public offering of its equity securities,  the
Company  shall  file as and when  applicable,  on a timely  basis,  all  reports
required  to be  filed by it under  the  Exchange  Act,  and take  such  further
reasonable  action as may be required from time to time and as may be within the
reasonable control of the Company, to enable the Holders to transfer the Warrant
Shares  without  registration  under the Securities Act within the limitation of
the exemptions provided by Rule 144 under the Securities Act or any similar rule
or regulation hereafter adopted by the Commission.

            (b) The Company shall not,  directly or  indirectly,  (i) enter into
any merger,  consolidation or  reorganization  in which the Company shall not be
the  surviving  corporation  or  (ii)  transfer  or  agree  to  transfer  all or
substantially   all  the  Company's   assets,   unless  prior  to  such  merger,
consolidation,  reorganization or asset transfer,  the surviving  corporation or
the  transferee,  respectively,  shall  have  agreed in  writing  to assume  the
obligations of the Company under this Agreement, and for that purpose references
hereunder to "Warrant  Shares" shall be deemed to include the  securities  which
the Holders of Warrant  Shares  would be  entitled  to receive in  exchange  for
Warrant Shares pursuant to any such merger, consolidation or reorganization.

            (c) The Company  shall not grant to any Person  (other than a Holder
of Warrant  Shares) any  registration  rights with respect to  securities of the
Company,  or enter  into any  agreement,  that  would be  inconsistent  with the
registration rights granted to Holders of Warrants herein.

            10.   MISCELLANEOUS.

            (a)  NO  INCONSISTENT  AGREEMENTS.  Each  of  the  Company  and  the
Purchaser  represent to the other that it has not entered into,  and agrees that
on or after the date of this  Agreement  it will not enter into,  any  agreement


                                       11
<PAGE>

which is  materially  inconsistent  with the rights  granted  to the  Holders of
Warrants or Warrant Shares in this Agreement or otherwise  materially  conflicts
with the provisions  hereof.  The Company  represents that the rights granted to
the Holders  hereunder  do not in any  material  way  conflict  with and are not
materially  inconsistent with the rights granted to the holders of the Company's
other issued and outstanding securities under any agreements.

            (b)  AMENDMENTS  AND  WAIVERS.  The  provisions  of this  Agreement,
including  the  provisions  of this  sentence,  may not be amended,  modified or
supplemented,  and waivers or consents to departures from the provisions  hereof
may not be given  unless the  Company and the Warrant  Agent have  obtained  the
written  consent of Holders of at least a majority of the  outstanding  Warrants
affected  by  such  amendment,  modification,  supplement,  waiver  or  consent;
PROVIDED that (i) any  amendment,  modification  or supplement to this Agreement
which,  in the good faith opinion of the Board (and evidenced by a resolution of
such board), does not adversely affect any Holder,  shall not be subject to such
requirement for written  consent;  and (ii) any amendment shall not be effective
unless the Warrant Agent shall have  received an opinion of counsel,  reasonably
satisfactory to it, that such amendment complies with the requirements hereof.

            (c) NOTICES.  All notices and other  communications  provided for or
permitted  hereunder  shall  be made in  writing  by  hand-delivery,  registered
first-class  mail,  telex,  telecopier,  or any courier  guaranteeing  overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 10(c);  (ii) if to the Company,  initially at the Company's  address set
forth in the Purchase Agreement and thereafter at such other address,  notice of
which is given in  accordance  with the  provisions of this Section  10(c);  and
(iii) if to the Purchaser, initially at the Purchaser's address set forth in the
Purchase  Agreement  and  thereafter at such other  address,  notice of which is
given in accordance with the provisions of this Section 10(c).

            All such  notices  and  communications  shall be deemed to have been
duly  given:  at the time  delivered  by hand,  if  personally  delivered;  five
business days after being  deposited in the mail,  postage  prepaid,  if mailed;
when answered back, if telexed; when receipt is acknowledged, if telecopied; and
on the next  business  day if timely  delivered  to an air courier  guaranteeing
overnight delivery.

                                       12

            (d)  SUCCESSORS  AND  ASSIGNS.  This  Agreement  shall  inure to the
benefit of and be binding upon the  successors,  assigns and transferees of each
of the parties, including, without limitation, subsequent Holders; PROVIDED that
nothing  herein  shall be deemed to permit  any  assignment,  transfer  or other
disposition  of Warrants in violation of the terms of the Purchase  Agreement or
the Warrant  Agreement.  If any transferee of any Holder shall acquire Warrants,
in any manner, whether by operation of law or otherwise,  such Warrants shall be
held subject to all of the terms of this  Agreement  and the Warrant  Agreement,
and by taking and holding such Warrants such person shall be conclusively deemed
to have agreed to be bound by and to perform all of the terms and  provisions of
this  Agreement  and the Warrant  Agreement and such person shall be entitled to
receive the benefits hereof.

            (e)  PURCHASES  AND SALES OF  WARRANTS.  The Company  shall not, and
shall use its  reasonable  best efforts to cause its  affiliates  (as defined in
Rule 405 under the Securities Act) not to, purchase and then resell or otherwise
transfer any Warrants other than Warrants acquired and cancelled.

            (f)  THIRD  PARTY  BENEFICIARY.  The  Holders  shall be third  party
beneficiaries  to the  agreements  made  hereunder  between  the Company and the
Purchaser,  and each  Holder  shall  have the right to enforce  such  agreements
directly  to the extent it deems such  enforcement  necessary  or  advisable  to
protect its rights or the rights of Holders hereunder.

            (g)  COUNTERPARTS.  This  Agreement may be executed in any number of
counterparts and by the parties hereto in separate  counterparts,  each of which
when so  executed  shall be  deemed  to be an  original  and all of which  taken
together shall constitute one and the same agreement.

            (h) HEADINGS.  The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

            (i) GOVERNING LAW. This  Agreement  shall be governed by the laws of
the State of New York.

            (j)  SEVERABILITY.  In  the  event  that  any  one  or  more  of the
provisions contained herein, or the application thereof in any circumstance,  is
held   invalid,   illegal  or   unenforceable,   the   validity,   legality  and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

            (k)  WAIVER OF  IMMUNITY.  To the  extent  that the  Company  has or
hereafter  may acquire any immunity from  jurisdiction  of any court or from any
legal process (whether through service of notice, attachment prior to judgement,


                                       13
<PAGE>

attachment in aid of execution,  execution or otherwise)  with respect to itself
or its property,  it hereby  irrevocably  waives such immunity in respect of its
obligations under this Agreement to the fullest extent permitted by law.

            (l)  INITIAL  PUBLIC  OFFERING.   Notwithstanding  anything  to  the
contrary herein contained, if the Company conducts an initial public offering of
equity securities (other than nonconvertible preferred shares), the Company will
give the Holders the  opportunity  to convert  such  Warrants  into  warrants to
purchase such equity securities (other than nonconvertible preferred shares) and
such  Warrant  Shares into such  equity  securities  (other than  nonconvertible
preferred shares).  Such conversion  opportunity will be on terms and conditions
determined to be fair and reasonable by the Company's Board.

            (m) ADDITIONAL  PURCHASERS.  From time to time the Company may issue
and sell additional Warrants to be issued under the Warrant Agreement,  together
with  shares  of  Series E  Preferred  Stock or  Series F  Preferred  Stock,  to
Additional Purchasers;  PROVIDED THAT, any such Additional Purchaser shall agree
to all of the  terms  and  conditions  of,  and  assume  all of the  rights  and
obligations of a "Purchaser"  under,  this Agreement and the Warrant  Agreement,
such  action  to  be  evidenced  by  such  Additional  Purchaser  executing  and
delivering to the Company a counterpart  to the signature page of this Agreement
(in the form  attached  hereto as Exhibit A) and the Warrant  Agreement  (in the
form set forth therein).  Other than such Additional Purchaser,  the Company and
the Warrant  Agent with  respect to the Warrant  Agreement,  and the Company and
such Additional  Purchaser with respect to this  Agreement,  no other party need
execute such counterparts in order for them to be effective.

            IN WITNESS  WHEREOF,  the parties have executed this Agreement as of
the date first written above.

     Borrower  may use for  Telecommunications  Equipment  not  manufactured  or
     produced by Lucent shall not exceed the lesser of

                    (x ) the aggregate  amount of Commitments  that Lucent shall
               have  syndicated to one or more  financial  institutions  without
               recourse to or credit support from Lucent and

                    (y ) 35% of the  aggregate  principal  amount  of the  Loans
               outstanding.

Except   as  set   forth  in   SCHEDULE   1.01(A),   Loans   with   respect   to
Telecommunications Equipment purchases may not be made to finance (1) soft costs
(including  installation,  delivery and engineering  costs) in excess of fifteen
percent (15%) of the invoiced price for the related Switch  Equipment or (2) any


                                       21
<PAGE>

support or installation  costs associated with an operational  system that would
not be capitalized in accordance with GAAP.

     (b)  Each  Base  Rate  Loan  shall  be in a  minimum  principal  amount  of
$1,000,000.  Each  LIBOR  Loan  shall  be  in  a  minimum  principal  amount  of
$5,000,000.

     (c) In any calendar month not more than one Loan may be requested.

     SECTION 2.03.  PROCEDURE FOR LOAN REQUEST AND BORROWING  COMMITMENT.  (a) A
Borrower  requesting  a Loan shall  deliver  to the Agent a Notice of  Borrowing
substantially in the form of EXHIBIT H-1 attached hereto on or before 11:00 a.m.
(New York time) at least five (5) Business  Days prior to the date on which such
Loan is requested to be made if such Loan is requested to be a LIBOR Loan and at
least three (3) Business  Days prior to the date on which such Loan is requested
to be made if such Loan is requested to be a Base Rate Loan, which notice,  once
given, shall be irrevocable;  PROVIDED,  that a Notice of Borrowing requesting a
Cash  Advance (as  hereinafter  defined)  must be received by the Agent at least
seven  (7)  Business  Days  prior to the  date on which  such  Cash  Advance  is
requested to be made if the amount of the requested Cash Advance is greater than
$50,000,000  and  PROVIDED,  FURTHER,  that in no event  may the  amount  of any
requested Cash Advance exceed $100,000,000. The Loans may be made (i) in cash in
accordance with the provisions of SECTION 2.03(B) (a "Cash Advance") and/or (ii)
by means of a credit  against  amounts due to Lucent  under the Lucent  Purchase
Agreement (or other agreement with Lucent), in accordance with the provisions of
SECTION 2.03(C) (a "Credit Advance"). The Loans made on the Initial Funding Date
shall be Base Rate Loans and  thereafter  may be continued as Base Rate Loans or
converted into LIBOR Loans in the manner provided in SECTION 2.06 and subject to
the other  conditions  and  limitations  therein set forth and set forth in this
ARTICLE II. In the case of a Loan the proceeds of which will be used to purchase
or reimburse  any  Borrower  for  Telecommunications  Equipment  (including  any
Telecommunications  Equipment  being  purchased or  reimbursed  under the Lucent
Purchase Agreement), the Notice of Borrowing delivered to the Agent will include
a schedule supporting one hundred percent (100%) of Telecommunications Equipment
requested  to be funded.  To the extent any portion of the Loans are not used to
fund  Telecommunications  Equipment  manufactured  or produced  by Lucent,  such
schedule  will detail all invoices for  equipment,  third party labor,  permits,
other third party costs and all capitalized internal costs of the Borrowers with
respect to such Telecommunications  Equipment permitted under GAAP. All invoices
over  $25,000 will be attached to such  schedule and  delivered to the Agent and
when combined with the above-described  capitalized  internal costs will support
seventy  percent  (70%) of the total  requested  funding.  In  addition,  if the
Telecommunications  Equipment is being purchased or reimbursed  under the Lucent
Purchase  Agreement,  and the Agent so requests,  a certificate  of delivery and
acceptance  in the  form of  EXHIBIT  P  shall  be  attached  to the  Notice  of
Borrowing.  In the case of a Loan the  proceeds  of which will be used to pay or
reimburse  any  Borrower for  transaction  costs,  the Notice of Borrowing  will
include  a copy of the  invoice  from  the  provider  of the  service  or  other
appropriate  supporting  documentation.  The  Notice of  Borrowing  shall,  with
respect to any Loans  requested,  specify whether such requested Loans are to be


                                       22
<PAGE>

made as Cash  Advances  or Credit  Advances,  are to bear  interest as Base Rate
Loans or LIBOR Loans,  and if such  requested  Loans are to be LIBOR Loans,  the
requested Interest Period for such Loans.

     (b) If any Notice of Borrowing  requests that a Cash Advance be made on the
date  specified  therein to finance  amounts  theretofore  paid by any  Borrower
(other  than  with the  proceeds  of  Loans)  under  invoices  submitted  to the
Borrower,  such Notice of Borrowing  shall  identify such  invoices  pursuant to
SECTION 2.03(A),  and, in accordance with SECTION 2.03(D), each Lender will make
available  to the Agent  such  Lender's  Pro Rata  Share of such  Cash  Advance.
Notwithstanding  the  foregoing,  Lucent  shall have the right,  upon giving the
Borrower  not less  than 30 days  prior  written  notice,  to  require  that the
Borrower  request  Cash  Advances  to  finance  amounts  previously  paid by the
Borrower (other than with the proceeds of Loans) under invoices submitted to the
Borrower by Lucent pursuant to the Lucent Purchase Agreement.

     (c) If any Notice of Borrowing  requests  that a Credit  Advance be made on
the date specified therein to finance amounts then due under invoices  submitted
to a Borrower,  such Borrowing  Notice shall identify such invoices  pursuant to
SECTION  2.03(A),  and, in accordance with SECTION  2.03(D),  each Lender (other
than  Lucent) will make  available to the Agent such  Lender's Pro Rata Share of
such Credit Advance.

     (d) The Agent agrees,  promptly  upon receipt of a Notice of Borrowing,  to
notify each Lender of the date and amount of the Loan  proposed  thereunder  and
the  amount of such  Lender's  Pro Rata  Share  therein.  So long as no Event of
Default has occurred and is continuing  and upon  fulfillment  of the applicable
conditions  set forth in ARTICLE IV, each such Lender  (other than Lucent in the
case of a Credit Advance)  severally  agrees,  on or before 12:00 P.M. (New York
time) on the date of each  proposed  Loan, to pay into the Payment  Account,  an
amount equal to such Lender's Pro Rata Share of such Loan in dollars and in same
day funds.  After the Agent's receipt of such Lender's Loan proceeds,  the Agent
shall make available  such proceeds to the Borrower  requesting the Loan (in the
case of a Cash Advance),  Lucent (in the case of a Credit Advance) or the Person
entitled to payment  thereof at the bank  account(s)  specified in the Notice of
Borrowing  on the date  specified  in such  Notice of  Borrowing  in  Dollars in
immediately  available  funds,  it being  understood  that Lucent  shall have no
obligation to make available to the Agent any funds for any Loan in respect of a
Credit Advance.

     (e) Unless the Agent has received written notice from a Lender prior to the
date of any proposed Loan that such Lender will not make  available to the Agent
such  Lender's Pro Rata Share of such Loan,  the Agent may, but is not obligated
to,  assume that such Lender has made its Pro Rata Share of such Loan  available
to the Agent on the date of such Loan in  accordance  with  PARAGRAPH (D) above,
and the Lenders may, in reliance  upon such  assumption,  make  available to the
Borrower on such date a corresponding  amount. If such Pro Rata Share is not, in
fact,  paid to Agent by such  Lender  when due,  the Agent will be  entitled  to
recover  such amount on demand from such Lender or the Borrower  which  received
the  proceeds of such Loan  without  set-off,  counterclaim  or deduction of any


                                       23
<PAGE>

kind, together with interest thereon,  for each day from the date such amount is
made  available  to such  Borrower  until the date such  amount is repaid to the
Agent  either  by such  Borrower  or such  Lender,  at,  (1) in the case of such
Borrower, the interest rate applicable to such Loan, and (2) in the case of such
Lender,  the Federal Funds  Effective  Rate.  Nothing in this SECTION 2.03(E) or
elsewhere  in this  Agreement  or the other  Loan  Documents  shall be deemed to
require  Agent to advance funds on behalf of any Lender or to relieve any Lender
from its  obligation  to fulfill its  Commitment  hereunder or to prejudice  any
rights that the  Borrower may have against any Lender as a result of any default
by such Lender  hereunder.  Without limiting the foregoing,  with respect to any
Lender which for any reason fails to make timely payment to the Agent of its Pro
Rata Share of any Loan,  the Agent,  in  addition to other  rights and  remedies
which it may have,  shall be entitled  to withhold or set off from any  payments
due to such Lender hereunder,  an amount equal to the Pro Rata Share required to
have been paid by such Lender plus interest as described  above, and to withhold
from such Lender any right of consent provided to such Lender by ARTICLE V or VI
of this  Agreement and to bring an action or suit against such Lender in a court
of competent jurisdiction to recover such Pro Rata Share thereof and any related
interest  thereon.  If such Lender  shall repay to the Agent such  corresponding
amount, such amount so repaid shall constitute such Lender's applicable Pro Rata
Share of such Loan for purposes of this Agreement.  If both such Lender and such
Borrower shall have repaid the  corresponding  amount,  the Agent shall promptly
return to such Borrower its corresponding amount.

     SECTION 2.04.  THE NOTES.  Each Borrower  shall execute and deliver to each
Lender a Note to evidence the  Commitment of that Lender.  Each Note shall be in
the principal amount of the Commitment  Amount of the applicable  Lender,  dated
the  Initial  Funding  Date,  stated  to  mature  on the  Termination  Date  and
substantially  in the form of  EXHIBIT E. The Notes  payable  to a Lender  shall
represent  the  obligation  of the  Borrower to pay the amount of each  Lender's
Commitment  Amount or, if less,  the  applicable  Lender's Pro Rata Share of the
aggregate  unpaid  principal  amount of all Loans to the Borrower  together with
interest  thereon as prescribed in SECTION 2.05. The aggregate  principal amount
of all the Notes shall not exceed the aggregate  Commitments of all the Lenders.
The Agent is hereby  authorized  by such  Borrower to record in the Register the
date and amount of each Loan made to such  Borrower,  and to record  therein the
date and  amount of each  payment on each Loan made to such  Borrower,  and such
recordation  shall be conclusive  evidence  against such Borrower of the amounts
owing to the Lenders with respect to the Loans in the absence of manifest error;
PROVIDED, that the failure of the Agent to register any such information on such
schedule shall not in any manner affect the obligation of such Borrower to repay
the Loans made to such Borrower in accordance with the terms of this Agreement.

     SECTION 2.05. INTEREST ON LOANS. (a) GENERAL.  Subject to the provisions of
SECTIONS  2.05(B),  2.06 and 2.07, each Loan shall bear interest at the rate per
annum  equal to (i) the Base Rate plus the  Applicable  Margin,  computed on the
basis of a 365 or 366 day year,  as  applicable,  or (ii) the LIBO Rate plus the
Applicable  Margin,  computed on the basis of a 360 day year, as selected by the
requesting   Borrower   in  the   Notice  of   Borrowing   and  the   Notice  of
Continuation/Conversion with respect to such Loan.



                                       24
<PAGE>

     (b) DEFAULT  INTEREST.  If any Borrower shall default in the payment of the
principal of or interest on any Loan or any other amount  becoming due hereunder
on its due date and such default shall continue uncured for three days, then the
Borrowers shall, on demand, from the Agent, thereafter pay interest on all Loans
at a rate that is four  percent  (4.00%)  per annum  above the rates of interest
otherwise payable on all the Loans (assuming the Total Leverage Ratio is greater
than  12.0 to 1.0) from the date such  payment  is due to the date such  payment
default is either cured or waived in writing by the  Requisite  Lenders.  If any
other Event of Default  shall occur and be  continuing  and shall be declared by
the Agent upon the direction of the Requisite Lenders, then the Borrowers shall,
on  demand,  thereafter  pay  interest  on all the  Loans at a rate  that is two
percent (2.00%) per annum above the rates of interest  otherwise  payable on the
Loans  (assuming the Total  Leverage Ratio is greater than 12.0 to 1.0) from the
date of the  occurrence  of such Event of  Default  until the date such Event of
Default has been cured or waived in writing by the Requisite  Lenders;  PROVIDED
that if an Event of Default  described in the first  sentence of this CLAUSE (B)
shall  occur at any  time  that an Event of  Default  described  in this  second
sentence has occurred and is continuing,  then the rate of interest described in
the first  sentence of this CLAUSE (B) shall  apply.  After the  occurrence  and
during the  continuance of any Event of Default,  the Borrowers shall be subject
to the limitations on borrowings of, conversions into and continuations as LIBOR
Loans set forth in SECTION 2.06(A).

     SECTION 2.06. CONVERSION OR CONTINUATION.  (a) Subject to the provisions of
SECTION 2.07, each Borrower shall have the option (i) to convert all or any part
of its  outstanding  Loans,  in a minimum  amount  of  $5,000,000  and  integral
multiples of $1,000,000 in excess of that amount,  from Loans that are Base Rate
Loans to LIBOR;  (ii) to convert all or any part of its  outstanding  Loans from
LIBOR  Loans  to Base  Rate  Loans  on the  expiration  of the  Interest  Period
applicable  thereto;  and  (iii)  upon the  expiration  of any  Interest  Period
applicable to its  outstanding  LIBOR Loan to continue all such LIBOR Loans as a
LIBOR  Loan;  PROVIDED  that no  outstanding  Loans may be  converted  into,  or
continued  as, LIBOR Loans when any Default or Event of Default has occurred and
is continuing.

     (b)  Whenever a Borrower  elects to convert or  continue  Loans  under this
SECTION  2.06,  such  Borrower  shall  deliver  to the  Agent a  written  notice
substantially  in the form of that attached  hereto as EXHIBIT H-2 (a "NOTICE OF
CONVERSION/ CONTINUATION"), signed by an authorized officer of such Borrower (i)
no later than 10:00 a.m. (New York time) two (2) Business Days in advance of the
requested conversion date, in the case of a conversion into Base Rate Loans, and
(ii) no later than 10:00 a.m (New York time) three (3) Business  Days in advance
of the requested  conversion or  continuation  date, in the case of a conversion
into, or  continuation  of, LIBOR Loans.  The Notice of  Conversion/Continuation
shall specify (1) the conversion or continuation date (which shall be a Business
Day), (2) the amount and type of the Loans to be converted or continued, (3) the
nature of the  requested  conversion or  continuation,  and (4) in the case of a
conversion into, or continuation of, LIBOR Loans, the requested Interest Period.
Promptly after receipt of a Notice of  Conversion/Continuation  pursuant to this
SECTION  2.06(B),  the Agent shall notify the Lenders by telecopy,  telephone or
other similar form of transmission, of the requested conversion or continuation.
In  the  event   that  a   Borrower   should   fail  to   provide  a  Notice  of


                                       25
<PAGE>

Conversion/Continuation  with respect to any LIBOR Loans as provided above, such
Loans, on the last day of the Interest Period with respect to such Loans,  shall
convert to Base Rate Loans.

     (c)  Any  Notice  of   Conversion/Continuation   for   conversion   to,  or
continuation  of, Loans made pursuant to this SECTION 2.06 shall be  irrevocable
and the applicable  Borrower shall be bound to convert or continue in accordance
therewith.

     SECTION 2.07. SPECIAL PROVISIONS GOVERNING LIBOR LOANS. Notwithstanding any
other  provisions  to the contrary  contained in this  Agreement,  the following
provisions shall govern with respect to LIBOR Loans as to the matters covered:

     (a) AMOUNT OF LIBOR LOANS.  Each  continuation  of or  conversion  to LIBOR
Loans shall be in a minimum  amount of $5,000,000  and in integral  multiples of
$1,000,000 in excess of that amount.

     (b)  DETERMINATION  OF INTEREST  PERIOD.  By giving  notice as set forth in
SECTION  2.06(B),  a  Borrower  shall  have the  option,  subject  to the  other
provisions of this SECTION 2.07, to specify whether the Interest Period for such
LIBOR Loan shall be a one, two, three or six month period.  The determination of
Interest Periods shall be subject to the following provisions:

          (i) In the  case of  immediately  successive  Interest  Periods,  each
     successive Interest Period shall commence on the day on which the preceding
     Interest Period expires.

           (ii) If any Interest Period would otherwise  expire on a day which is
      not a Business Day, the Interest Period shall be extended to expire on the
      next  succeeding  Business  Day;  PROVIDED  that  if the  next  succeeding
      Business Day occurs in the following  calendar  month,  then such Interest
      Period shall expire on the immediately preceding Business Day.

          (iii) A Borrower may not select an Interest Period for any LIBOR Loan,
      which Interest Period expires later than the maturity date of such Loan.

           (iv) A Borrower may not select an Interest Period with respect to any
      portion of such  Borrower's  Loans  which  extends  beyond an  installment
      payment date for such Loans unless, after giving effect to such selection,
      the  portion of such Loans not subject to Interest  Periods  ending  after
      such  installment  payment date is equal to or greater than the  principal
      due on such installment payment date.

            (v) There shall be no more than four (4) Interest  Periods in effect
      at any one time.



                                       26
<PAGE>

     (c) DETERMINATION OF INTEREST RATE. As soon as practicable after 10:00 a.m.
(New York time) on the LIBOR Interest Rate  Determination  Date, the Agent shall
determine (which  determination,  absent manifest error,  shall be presumptively
correct)  the  interest  rate for the LIBOR Loans for which an interest  rate is
then being  determined  and shall promptly give notice thereof (in writing or by
telephone confirmed in writing) to the applicable Borrower. In the event that on
any LIBOR  Interest  Rate  Determination  Date the Agent  shall have  determined
(which determination,  absent manifest error, shall be presumptively correct and
binding upon all parties) that:

            (i)  adequate  and fair  means do not  exist  for  ascertaining  the
      applicable  interest  rates by reference to which the LIBO Rate then being
      determined is to be fixed; or

           (ii) the LIBO Rate plus the Applicable Margin for any Interest Period
      for such  Loans  will not  adequately  reflect  the cost to any  Lender of
      making,  funding or maintaining  its LIBOR Loan for such Interest  Period,
      the Agent  shall  forthwith  so notify  the  applicable  Borrower  and the
      Lender, whereupon:

            (A)   each  LIBOR  Loan will  automatically,  on the last day of the
                  then existing  Interest Period  therefor,  convert into a Base
                  Rate Loan; and

            (B)   the  obligation  of the Lenders to make,  or to convert  Loans
                  into,  LIBOR  Loans shall be  suspended  until the Agent shall
                  notify  the  applicable  Borrower  and the  Lenders  that  the
                  circumstances causing such suspension no longer exist.

     (d) ILLEGALITY.  Notwithstanding any other provision of this Agreement,  if
any Lender shall notify the Agent that the  introduction  of or any change in or
in the interpretation of any law or regulation makes it unlawful, or any central
bank or other Governmental Authority asserts that it is unlawful, for any Lender
to perform its obligations  hereunder to make LIBOR Loans or to fund or maintain
LIBOR Loans hereunder,  (i) the obligation of the Lenders to make, or to convert
Loans into or to continue  Loans as,  LIBOR Loans shall be  suspended  until the
Agent shall notify the Borrowers and the Lenders that the circumstances  causing
such  suspension no longer exist and (ii) the Borrowers shall on the termination
of the Interest Period then applicable thereto, or on such earlier date required
by law,  prepay in full all LIBOR Loans then  outstanding  together with accrued
interest  thereon,  or  convert  all such  LIBOR  Loans  into Base Rate Loans in
accordance with SECTION 2.06.

     (e) COMPENSATION. In addition to such amounts as are required to be paid by
the Borrowers  pursuant to the other  Sections of this ARTICLE II, the Borrowers
agree to  compensate  any  Lender  for all  losses,  expenses  and  liabilities,
including,  without  limitation,  any loss or expense  incurred by reason of the
liquidation or  reemployment  of deposits or other funds acquired by such Lender


                                       27
<PAGE>

to fund or maintain such Lender's LIBOR Loans  (including the Applicable  Margin
component  thereof) to the  Borrowers,  which such Lender may sustain (i) if for
any  reason a funding  of any  LIBOR  Loans  does not occur on a date  specified
therefor in a Notice of  Borrowing  or Notice of  Conversion/Continuation,  or a
successive  Interest  Period does not commence  after  notice  therefor is given
pursuant to SECTION  2.06 as a result of any act or  omission  of any  Borrower,
(ii) if any voluntary or mandatory  prepayment of any LIBOR Loans occurs for any
reason on a date  which is not the last  scheduled  day of an  Interest  Period,
(iii) as a  consequence  of any required  conversion of LIBOR Loans to Base Rate
Loans as a result of any of the events indicated in SECTION 2.07(D),  or (iv) as
a  consequence  of any other  failure by the  Borrower to repay LIBOR Loans when
required by the terms of this Agreement.

     (f) BOOKING OF LIBOR LOANS; DISCRETION AS TO MANNER OF FUNDING. The Lenders
may make,  carry or  transfer  LIBOR Loans at, to, or for the account of, any of
their  respective  branch  offices  or the  office  of any of  their  respective
affiliates.  Each Lender  shall be entitled to fund and  maintain its funding of
all or any part of its Loans in any manner it sees fit, it being understood that
for  purposes  of this  Agreement  all  determinations  hereunder  shall be made
assuming each Lender had actually  funded and maintained each LIBOR Loan through
the  purchase  of deposits of Dollars in the London  Interbank  market  having a
maturity  corresponding  to each Loan's  Interest Period and bearing an interest
rate equal to the LIBO Rate for such Interest Period.

     SECTION 2.08. PAYMENTS. (a) Interest on each LIBOR Loan shall be payable in
arrears on each LIBOR  Interest  Payment Date and, if such LIBOR Loan is paid in
full  other than on such  LIBOR  Interest  Payment  Date,  on such  other  date.
Interest on each Base Rate Loan will be payable in arrears on each  Payment Date
and, if such Base Rate Loan is paid in full other than on such Payment  Date, on
such other date.

     (b) Subject to the  provisions of SECTIONS 2.09 and 9.02,  the  outstanding
principal  balance of the Loans made to the Borrowers shall be payable in twenty
consecutive  quarterly  payments  commencing  on the Payment  Dates set forth in
Annex C. On each such Payment Date,  the Borrowers  shall pay an amount equal to
the product of the  percentage  set forth on Annex C opposite  such Payment Date
multiplied by the aggregate principal amount of the Loans made.

     (c)  Payments  made with  respect  to the Loans by each  Borrower  shall be
applied by the Agent first to unpaid and accrued  fees and  interest and then to
the  outstanding  unpaid  principal  balance  of the  Loans  of  such  Borrower;
PROVIDED,  that upon the  occurrence  and during the  continuance of an Event of
Default,  all payments and  prepayments  with respect to the Obligations and all
proceeds of Collateral shall be applied in the following order by the Agent; (it
being  understood that the order of priority set forth in the following  clauses
may be altered upon direction from the Requisite Lenders to the Agent):

     (1) first,  to pay  Obligations  in respect  of any  expenses  then due and
     payable by the Borrowers to the Agents or the Lenders;



                                       28
<PAGE>

     (2)  second,  to  pay  Obligations  in  respect  of  any  reimbursement  or
     indemnities then due and payable to the Agents or the Lenders;

     (3) third,  to pay  Obligations in respect of any fees due and owing to the
     Agent or the Collateral Agent;

     (4) fourth,  to pay  Obligations  in respect of the  commitment fee and any
     other fees and commissions then due and owing to the Agents or the Lenders;

     (5) fifth, to pay Obligations in respect of any accrued and unpaid interest
     due in respect of Loans;

     (6) sixth,  to pay  termination  payments  due and payable  pursuant to any
     Interest Rate Agreement or other hedging agreement;

     (7) to the ratable  payment or prepayment  of principal of any  outstanding
     Loans; and

     (8) to the ratable payment of all other Obligations.

     SECTION  2.09.  OPTIONAL AND MANDATORY  PREPAYMENT  OF LOANS;  OPTIONAL AND
MANDATORY  REDUCTION OF COMMITMENT AMOUNT. (a) Provided that no Event of Default
has  occurred and is  continuing,  the  Borrowers  shall have the right upon the
provision of sixty (60) days' prior written  notice to the Agent,  which notice,
once given,  shall be irrevocable,  on any Payment Date with respect to any Base
Rate Loans and on the last day of the applicable Interest Period with respect to
any LIBOR Loans, to prepay the outstanding principal of the Base Rate Loans in a
minimum  principal  amount of  $1,000,000  and  increments of $250,000 in excess
thereof, or the outstanding  principal of the LIBOR Loans in a minimum principal
amount of $5,000,000 and increments of $1,000,000 in excess  thereof,  together,
in each case, with accrued interest thereon and the aggregate Prepayment Premium
applicable  thereto.  The amount of principal so prepaid shall be applied to the
remaining  principal payments of the type of Loans prepaid (i.e. Base Rate Loans
or LIBOR Loans) in the inverse order of maturity.

     (b) Upon the  occurrence of any Event of Loss in excess of $1,000,000  with
respect to any item of  Collateral  that is not  repaired  or  replaced,  or any
Events of Loss which,  in the aggregate,  exceed  $5,000,000 with respect to any
item or items of  Collateral  that are not  repaired or replaced  (in each case,
other than an item of Collateral no longer used or useful in the Business)  such
that after such repair or replacement it has a value at least equal to its value
prior to the  occurrence  of such  Event  of Loss,  the  Borrower  shall  make a
principal  prepayment within thirty (30) days of such Event of Loss in an amount
equal to the  replacement  value of the item of Collateral  which  suffered such
Event  of  Loss,  together  with  accrued  interest  thereon  (but  without  the


                                       29
<PAGE>

Prepayment  Premium) with such principal  payment to be applied,  to outstanding
principal balance of the Loans.

     (c) The Borrowers shall prepay Loans in a principal amount equal to (i) all
the net proceeds of any sales of assets of any Borrower  other than sales in the
ordinary course of business,  which proceeds are not reinvested  within 270 days
after receipt thereof in replacement assets, plus, in the case of any Loans held
by Lenders other than Lucent, the applicable  Prepayment  Premium,  and (ii) the
proceeds of insurance  policies paid to any Borrower and not applied  within 270
days after any such payment to replacing, rebuilding or restoring the Collateral
which was the subject of insurance loss, without any Prepayment Premium, in each
case,  within  five (5) days  after the  expiration  of the  applicable  270 day
period.

     (d) Provided  that no Event of Default has occurred and is  continuing  and
that the Borrower can  demonstrate to the Agent that it has adequate funds as to
ensure  that all work to be  performed  with  respect to any  System  then under
construction  shall be performed  and that each such System shall be a Completed
System on or before  December 31, 2000, the Borrowers  shall have the right upon
the provision of thirty days' prior written  notice to the Agent,  which notice,
once given, shall be irrevocable,  on any Payment Date, to reduce the Commitment
Amount of all the Lenders.  Each such reduction shall be in a minimum  principal
amount of $1,000,000 and increments of $250,000 in excess thereof.

     (e) Any  reduction  in the  Commitment  Amount of all the Lenders  shall be
allocated  to each  Lender  based  on its Pro Rata  Share.  All  prepayments  of
principal  shall be applied to the remaining  principal  payments of the type of
Loans prepaid in the inverse order of maturity.

     SECTION 2.10.  FEES. (a) The Borrowers shall pay and the Borrowers shall be
jointly  and  severally  liable to the Agent for the  account of the Lenders for
payment of a nonutilization fee calculated on a per annum basis and equal to (1)
in the case of each Lender other than Lucent, the product of (x) 1.25% per annum
multiplied by (y) the average  unused  Commitment  Amount of such Lender for the
quarterly  period  preceding a Payment Date  (PROVIDED that until the conditions
set  forth  in  SECTION  4.03  and  SECTION  4.04  have  been  satisfied,   such
nonutilization  fee shall be paid only on the  Commitment  Amount which together
with  Loans  then  outstanding  aggregate  $250,000,000)  and (2) in the case of
Lucent,  the product of (x) 1.25% per annum  multiplied by (y) the lesser of (A)
the average of the unused Commitment Amount of Lucent and (B) the average of the
excess of (I)  $250,000,000  over  (II) the  principal  amount of Loans  held by
Lucent,  in each case, for the quarterly  period  preceding a Payment Date. Such
fees shall be payable on each Payment Date  following such last day of a quarter
beginning on the Payment Date following the Closing Date until and including the
Payment Date following the Commitment Termination Date:

In  the  event  that  at any  time  the  Borrowers  fails  to  comply  with  the
requirements of SECTION 2.03(D) for any calendar year, the  nonutilization  fees
shall be increased by 100 basis points for the entire calender year with payment
of such increment in the nonutilization fee being due and payable not later than
the last Business Day of such calendar year.



                                       30
<PAGE>

     (b) The  Borrowers  shall  pay and  the  Borrowers  shall  be  jointly  and
severally liable to the Agent and the Collateral Agent, for payment of an annual
administrative  fee and a  collateral  monitoring  fee at the  times  and in the
amounts set forth in the Fee Letters.

     (c) The Borrowers shall on the Closing Date pay the Agent the  underwriting
fee and the structuring fee referred to in the Fee Letter.

     (d) All fees once paid shall be nonrefundable.

     SECTION  2.11.  MANNER OF  PAYMENT;  SPECIAL  TAX  CONSIDERATIONS.  (a) All
payments  by the  Borrowers  hereunder  and under the Notes shall be made to the
Agent by wire transfer or other electronic payment method to the Payment Account
or to such bank  account  as the Agent may  designate,  for the  account  of the
Lenders in Dollars in immediately  available funds by 11:00 a.m., New York time,
on the  date on which  such  payment  shall  be due.  The  Agent  will  promptly
thereafter  cause to be  distributed  like  funds  relating  to the  payment  of
principal or interest or other fees ratably (other than amounts payable pursuant
to SECTION 2.13) to each Lender in accordance  with SECTION  10.07.  Interest in
respect of any Loan hereunder  shall accrue from the day such Loan is made up to
and  including  the day  prior to the date on which  such  Loan is paid in full.
Payments  received  after 12:00 p.m.  shall not be given  credit  until the next
Business Day, and the Borrowers shall be liable for interest,  if any,  accruing
on such payment until the next Business Day.

     (b)(1) Any and all payments by each Borrower  hereunder  shall be made free
and clear of and without  deduction for any and all Taxes. If any Borrower shall
be  required  by law to deduct any Taxes  from or in respect of any sum  payable
hereunder or under the other Loan Documents to any Lender or Agent,  (A) the sum
payable shall be increased as may be necessary so that after making all required
deductions  (including  deductions  applicable to additional  sums payable under
this SECTION  2.11) such Lender or Agent  receives an amount equal to the sum it
would have received had no such  deductions  been made,  (B) such Borrower shall
make such  deductions,  and (C) such Borrower shall pay the full amount deducted
to the  relevant  taxation  authority  or other  authority  in  accordance  with
applicable  law.  If a  withholding  tax of the United  States of America or any
other Governmental Authority shall be or become applicable (y) after the date of
this  Agreement,  to the payments by any Borrower made to the Lending  Office or
any other  office  that a Lender may claim as its Lending  Office,  or (z) after
such Lender's  selection and  designation of any other Lending  Office,  to such
payments made to such other  Lending  Office,  such Lender shall use  reasonable
efforts to make,  fund and maintain its Loans through  another Lending Office of
such  Lender in  another  jurisdiction  so as to reduce to the  greatest  extent
possible,  but not increase,  the applicable Borrower's liability hereunder,  if
the making,  funding or  maintenance  of such Loans  through such other  Lending
Office of such  Lender  does not,  in the  judgment  of such  Lender,  otherwise
materially  adversely  affect such Loans,  such Lender's  obligations  under its
Commitment or such Lender.  Notwithstanding  anything to the contrary hereunder,
if a Person becomes a Lender under this Agreement pursuant to SECTION 11.08, the


                                       31
<PAGE>

Borrowers  shall in no event be  required to  increase  any payment  pursuant to
paragraph  (b) of this SECTION 2.11 by an amount that would exceed the amount of
any  increase  that would be  required  to be made under  paragraph  (b) of this
SECTION 2.11 to the assigning Lender.

     (2) The Borrowers will jointly and severally  indemnify each Lender and the
Agent and hold them  harmless for the full amount of Taxes  (including,  without
limitation,  any Taxes imposed by any Governmental  Authority on amounts payable
under this SECTION 2.11 or any other documentary  taxes,  assessments or charges
made by any  Governmental  Authority by reason of the  execution and delivery of
this  Agreement or any other Loan Document) paid by such Lender or the Agent (as
the case may be) and any liability (including penalties, interest, and expenses)
arising therefrom or with respect thereto.  This  indemnification  shall be made
within thirty (30) days after the date such Lender or the Agent (as the case may
be) makes written demand  therefor.  A certificate  as to any additional  amount
payable to any Lender or the Agent  under this  SECTION  2.11  submitted  to the
Borrowers  and the Agent (if a Lender is so  submitting)  by such  Lender or the
Agent shall show in reasonable  detail the amount  payable and the  calculations
used to determine such amount. With respect to such deduction or withholding for
or on account of any Taxes and to confirm  that all such Taxes have been paid to
the appropriate Governmental  Authorities,  the Borrowers shall promptly (and in
any event not later than thirty (30) days after receipt)  furnish to each Lender
and the Agent such certificates, receipts and other documents as may be required
(in the  reasonable  judgment of such Lender or the Agent) to establish  any tax
credit to which such Lender or the Agent may be entitled.

     (3)  Within  thirty  (30) days  after the date of any  payment  of Taxes on
amounts  payable  hereunder by any  Borrower,  such Borrower will furnish to the
Agent, at its address  referred to in SECTION 11.01, the original or a certified
copy of a receipt evidencing payment thereof.

     (4)  Without  prejudice  to the  survival  of any  other  agreement  of the
Borrowers  hereunder,  the agreements and obligations of such Borrower contained
in this SECTION 2.11 shall survive the payment in full of principal and interest
hereunder and the termination of this Agreement.

     (5) Each  Lender  that is not  created or  organized  under the laws of the
United States of America or a political subdivision thereof shall deliver to the
Borrowers  and the Agent on or before the effective  date hereof,  or, if later,
the date on which such Lender becomes a Lender pursuant to SECTION 11.08, a true
and accurate  certificate  executed in duplicate by a duly authorized officer of
such Lender,  in a form  satisfactory  to the  Borrowers  and the Agent,  to the
effect:

      (A) that such Lender is capable under the  provisions of an applicable tax
      treaty  concluded  by the  United  States of  America  (in which  case the
      certificate shall be accompanied by two original,  executed copies of Form


                                       32
<PAGE>

      1001 of the IRS or any  successor  form) or under  Section 1442 of the IRC
      (in which  case the  certificate  shall be  accompanied  by two  original,
      executed  copies  of  Form  4224  of the  IRS or any  successor  form)  of
      receiving  payments of interest hereunder exempt from or at a reduced rate
      of deduction or withholding of United States federal income tax, or

      (B)  if  such  Lender  is not a  "bank"  within  the  meaning  of  Section
      881(c)(3)(A) of the IRC and intends to claim  exemption from U.S.  federal
      withholding  tax under  Section  871(h) or Section  881(c) of the IRC with
      respect to payments of "portfolio interest", (i) that such Lender is not a
      "bank"  within  the  meaning  of  Section  881(c) of the IRC,  is not a 10
      percent  shareholder  (within the meaning of Section  871(h)(3)(B)  of the
      IRC) of any Borrower and is not a controlled foreign  corporation  related
      to any Borrower (within the meaning of Section 864(d)(4) of the IRC), (ii)
      that such Lender claims complete  exemption from U.S. federal  withholding
      tax on payments of interest by the Borrowers  under this Agreement and the
      other Loan Documents and (iii) that the Lender has received in replacement
      of any Note held by or assigned to it, a QFL Note in accordance  with this
      SECTION 2.11(B).

Each such Lender  further  agrees to deliver to the Borrowers and the Agent from
time to time a true and  accurate  certificate  executed in  duplicate by a duly
authorized  officer of such Lender  substantially in a form  satisfactory to the
Borrowers  and the Agent,  before or promptly  upon the  occurrence of any event
requiring a change in the most recent certificate  previously delivered by it to
the Borrowers and the Agent pursuant to this SECTION 2.11(B)(5).  Further,  each
Lender  which  delivers  a  certificate  accompanied  by  Form  1001  of the IRS
covenants  and agrees to deliver to the Borrower  and the Agent  within  fifteen
(15) days  prior to the date on which the first  payment  becomes  payable to it
hereunder  or  under  any  Note,  and  every  third  anniversary  of  such  date
thereafter, on which this Agreement is still in effect, another such certificate
and two  accurate  and  complete  original  signed  copies  of Form 1001 (or any
successor form or forms  required  under the IRC or the  applicable  regulations
promulgated thereunder), and each Lender that delivers a certificate accompanied
by Form 4224 of the IRS  covenants and agrees to deliver to the Borrower and the
Agent within fifteen (15) days prior to the beginning of each subsequent taxable
year of such Lender during which this Agreement is still in effect, another such
certificate  and two accurate and complete  original  signed  copies of IRS Form
4224 (or any successor  form or forms  required  under the IRC or the applicable
regulations promulgated  thereunder).  Each such certificate shall certify as to
one of the following:

     (a) that such Lender is capable of receiving payments of interest hereunder
exempt from or at a reduced rate of deduction or withholding of United States of
America federal income tax;

     (b) that such  Lender is not  capable of  receiving  payments  of  interest
hereunder exempt from or at a reduced rate of deduction or withholding of United
States federal income tax as specified  therein but is capable of recovering the


                                       33
<PAGE>

full amount of any such  deduction or  withholding  from a source other than the
Borrowers and will not seek any such recovery from the Borrowers; or

     (c) that, as a result of the adoption of or any change in any law,  treaty,
rule, regulation,  guideline or determination of a Governmental Authority or any
change in the interpretation or application thereof by a Governmental  Authority
after the date such Lender became a party hereto,  such Lender is not capable of
receiving  payments of interest  hereunder  without  deduction or withholding of
United States of America federal income tax as specified  therein and that it is
not capable of  recovering  the full amount of the same from a source other than
the Borrowers.

     Each Lender  shall  promptly  furnish to the  Borrowers  and the Agent such
additional documents as may be reasonably required by the Borrowers or the Agent
to  establish  any  exemption  from or  reduction  of any Taxes  required  to be
deducted or withheld  and which may be obtained  without  undue  expense to such
Lender

     (6) For a period  with  respect to which a Lender has failed to provide the
Agent and the  Borrowers  with the  appropriate  form  described in this SECTION
2.11(B)(5)  (other  than if such  failure  is due to a change  in law  occurring
subsequent to the date on which a form  originally was required to be provided),
such Lender  shall not be entitled to  indemnification  under this  SECTION 2.11
with respect to Taxes  imposed by the United  States by reason of such  failure;
PROVIDED, that should a Lender become subject to Taxes because of its failure to
deliver a form required  hereunder,  the Borrowers shall take such steps as such
Lender shall reasonably request to assist such Lender to recover such Taxes.

     (7)  Any  Lender  that  is not a  "bank"  within  the  meaning  of  Section
881(c)(3)(A)  of the IRC and satisfies the  applicable  requirements  of SECTION
2.11(B)(5)  (a  "Qualified  Foreign  Lender")  shall upon receipt of the written
request of the Agent or the Borrowers  and may, upon its own written  request to
the Agent,  exchange any Note held by or assigned to it for a qualified  foreign
lender  Note ( a "QFL  Note").  A QFL  Note  shall  be in the  form of the  Note
attached as Exhibit E but shall contain the following legend,"This Note is a QFL
Note, and as such, ownership of the obligation  represented by such QFL Note may
be  transferred  only in  accordance  with Section 2.11 of the Loan and Security
Agreement."  Any QFL Note issued in replacement of any existing Note pursuant to
this Section shall be (i) dated the Closing Date, (ii) issued in the name of the
entity in whose name such  existing Note was issued and (iii) issued in the same
principal  amount as such  existing  Note.  Any Note  replaced  pursuant to this
Section is sometimes referred to herein as a "Replaced Note".

     (8) Each Borrower agrees that, upon the request of or delivery of a request
to a Qualified Foreign Lender pursuant to paragraph (7) of this SECTION 2.11(B),
it shall  execute  and  deliver  a QFL Note to the Agent in  replacement  of the
Replaced  Note  surrendered  in connection  with such request  conforming to the
requirements  of this paragraph.  Each Qualified  Foreign Lender shall surrender
its Note in connection with any replacement  pursuant to this SECTION 2.11. Upon


                                       34
<PAGE>

receipt by the Agent, in connection with any replacement,  of a QFL Note and the
existing Note to be replaced by such QFL Note in accordance with this paragraph,
the Agent shall  forward the QFL Note to the Lender  which has  surrendered  its
Note for replacement by such QFL Note and shall forward the surrendered  Note to
the relevant  Borrower marked  "canceled".  Once issued,  QFL Notes (i) shall be
deemed to and shall be "Notes" for all purposes under the Loan  Documents,  (ii)
may not be exchanged for Notes which are not QFL Notes, notwithstanding anything
to the contrary in the Loan Documents and (iii) shall at all times thereafter be
QFL Notes, including,  without limitation,  following any transfer or assignment
thereof.

     (9) Notwithstanding anything to the contrary in the Loan Documents, the QFL
Notes are  registered  obligations  as to both  principal  and  interest  with a
Borrower  and  transfer  of the  obligations  underlying  such  QFL  Note may be
effected  only  by  surrender  of the  QFL  Note to  such  Borrower  and  either
reissuance  by such  Borrower of such QFL Note to the  transferee or issuance by
such  Borrower  of a new QFL  Note to the  transferee.  A QFL  Note  shall  only
evidence the Lender's or an assignee's  right,  title and interest in and to the
related  obligation,  and in no event is a QFL  Note to be  considered  a bearer
instrument  or  obligation.  This  SECTION  2.11 shall be  construed so that the
obligations  underlying the QFL Notes are at all times maintained in "registered
form" within the meaning of Sections 871(h)(2) and 881(c)(3) of the IRC.

     (c)(1) If a Borrower  pays any  additional  amount  under this SECTION 2.11
and, as a result, any Lender,  together with the Agent,  subsequently,  in their
sole discretion and based on their own  interpretation of any relevant laws (but
acting in good faith) receive or are granted a final and  non-appealable  credit
against or deduction  from or in respect of any tax payable by such  Lender,  or
obtain any other final and non-appealable relief in respect of any tax, which in
the  opinion  of such  Lender  and the  Agent,  acting  in good  faith,  is both
reasonably  identifiable and quantifiable by them without  requiring any Lender,
the Agent or their professional  advisers to expend a material amount of time or
incur a material cost in so identifying or quantifying (any of the foregoing, to
the extent so reasonably  identifiable and quantifiable,  being referred to as a
"SAVING"),  such Lender shall, to the extent that it can do so without prejudice
to the  retention of the Saving,  reimburse  such Borrower  promptly  after such
identification and quantification with the amount of such Saving; PROVIDED, that
any such  Saving  shall be reduced by any costs  incurred  by such Lender or the
Agent in obtaining such Saving.

     (2) Nothing in this SECTION 2.11(C) shall require any Lender to disclose to
any Person any  information  regarding its tax affairs or to arrange its tax and
other affairs in any particular manner.

     SECTION 2.12. MAXIMUM LAWFUL INTEREST RATE.  Notwithstanding  any provision
contained  herein,  the total liability of the Borrowers for payment of interest
pursuant hereto and the Notes,  including any other charges or other amounts, to
the extent such charges and other  amounts are deemed to be interest,  shall not
exceed the  maximum  amount of such  interest  permitted  by law to be  charged,


                                       35
<PAGE>

collected,  or received from the Borrowers (the "MAXIMUM RATE"). If any payments
by any Borrower for the account of any Lender include  interest in excess of the
Maximum Rate, such Lender shall apply such excess to the reduction of the unpaid
principal amount owing by such Borrower, or if none is due, such excess shall be
returned to such Borrower.

     SECTION 2.13.  FUNDING ISSUES.  (a) INCREASED  COSTS. If, due to either (i)
the  introduction  after the date hereof of, or any change after the date hereof
in or in the  interpretation  of, any applicable  law, rule or regulation by any
Governmental  Authority,  central  bank or  comparable  agency  charged with the
interpretation or administration  thereof or (ii) compliance by any Lender after
the date hereof with any final request or final directive  issued after the date
hereof  (whether  or not  having  the  force  of law) by any  such  Governmental
Authority,  central bank or  comparable  agency,  and, as a result of any of the
events  set forth in the above  CLAUSES  (I) and  (II),  (x) there  shall be any
increase in the cost to such Lender in  maintaining  its  Commitment  under this
Agreement or funding or  maintaining  its Pro Rata Share of the Loans under this
Agreement,  or (y) any Lender is subjected to any charge or  withholding  on its
obligations  hereunder,  or changes in the basis of  taxation of payments to any
Lender in connection  with any of the foregoing  (except for changes in the rate
of tax on overall net income of any Lender)  (collectively,  "INCREASED COSTS"),
then the Borrowers  shall,  from time to time, pay, to the Agent for the benefit
of such Lender  within 15 days after such Lender shall have  provided  notice to
the Agent (and the Agent shall have  provided  notice to the  Borrowers) of such
Increased  Cost,  an  amount  sufficient  to  compensate  such  Lender  for such
Increased Cost, as provided  herein.  A certificate  setting forth in reasonable
detail the  computation of the amount of such Increased Cost (which  increase in
cost shall be determined by such Lender's reasonable allocation of the aggregate
of such cost increases resulting from such event), submitted to the Borrowers by
such Lender,  absent  manifest  error,  shall be conclusive  and binding for all
purposes.

     (b) INCREASED  CAPITAL.  If any Lender which is subject to minimum  capital
requirements  determines that  compliance by such Lender,  with any guideline or
request from any central bank or other  Governmental  Authority  (whether or not
having the force of law) affects or would affect the amount of capital  required
or expected to be maintained by such Lender, or any corporation controlling such
Lender, and such Lender reasonably determines that the amount of such capital is
increased  by or based  upon any  commitment  to lend  hereunder  or  making  or
maintaining  Loans,  then,  upon demand by such Person,  the Borrowers agree to,
within five (5) days of such demand,  pay to such  Person,  from time to time as
specified by such Person,  additional  amounts  sufficient  to  compensate  such
Person in the  light of such  circumstances,  to the  extent  that  such  Person
reasonably  determines such increase in capital to be allocable to such Person's
commitment or maintenance of Loans hereunder.  A certificate as to the amount of
such increased cost, submitted to the Borrowers by the applicable Person, absent
manifest  error,  shall be  conclusive  and  binding  on the  Borrowers  for all
purposes.

     (c) REPLACEMENT OF LENDER. If any Borrower, as a result of the requirements
of either  SECTION  2.13(A) or SECTION  2.13(B),  shall be  required  to pay any
particular Lender (an "AFFECTED  LENDER") the additional  amounts referred to in


                                       36
<PAGE>

such  Section,  which  costs  are not  imposed  by the other  Lenders,  and such
additional amounts are material,  then such Borrower shall be entitled to find a
replacement Lender,  reasonably acceptable to the Agents (the Agents' consent to
such  replacement  Lender  not to be  unreasonably  withheld),  to  replace  the
Affected Lender. The Affected Lender and the replacement Lender shall execute an
Assignment  Agreement with respect to all of the Affected  Lender's  Commitments
and all Loans owing to the Affected Lender and comply with the other  provisions
of SECTION 11.08(c).  Upon the payment by the replacement Lender to the Affected
Lender of the then  outstanding  principal amount of Loans owing to the Affected
Lender,  together with accrued interest thereon, and the payment by the Borrower
to the Affected Lender of any compensation  required with respect to LIBOR Loans
pursuant to SECTION 2.07(E),  the replacement Lender shall succeed to all of the
Affected Lender's rights and obligations under this Agreement and the other Loan
Documents.

                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

401(a) of the IRC has been  determined by the IRS to be so  qualified,  and each
trust  related to any such Plan has been  determined  to be exempt from  federal
income tax under  Section  501(a) of the IRC.  Except as  disclosed  on SCHEDULE
3.11, neither such Borrower nor any ERISA Affiliate  maintains or contributes to
any  employee  welfare  benefit plan within the meaning of Section 3(1) of ERISA
which provides  benefits to employees after termination of employment other than

Affiliate  has  breached  any of the  responsibilities,  obligations  or  duties
imposed on it by ERISA or regulations promulgated thereunder with respect to any
Plan  which  breach  could  result in a  Material  Adverse  Effect.  No Plan has
incurred any accumulated  funding deficiency (as defined in Section 302(a)(2) of
ERISA and Section 412(a) of the IRC), whether waived or not waived. Neither such
Borrower nor any ERISA  Affiliate  nor any  fiduciary of any Plan which is not a
Multiemployer  Plan (i) has  engaged  in a  nonexempt  "prohibited  transaction"
described  in Section 406 of ERISA or Section  4975 of the IRC or (ii) has taken

Event.  Neither such Borrower nor any ERISA Affiliate has incurred any liability
to the PBGC  which  remains  outstanding  and which  could  result in a Material
Adverse  Effect,  other than the payment of  premiums,  and there are no premium
payments  which have become due which are unpaid.  Schedule B to the most recent
annual  report  filed  with the IRS with  respect to each Plan is  complete  and
accurate.  Since the date of each such  Schedule  B,  there has been no  adverse
change in the funding status or financial condition of the Plan relating to such
Schedule B. Neither such Borrower nor any ERISA Affiliate has (i) failed to make
a  required  contribution  or  payment  to a  Multiemployer  Plan or (ii) made a
complete  or  partial  withdrawal  under  Sections  4203 or 4205 of ERISA from a
Multiemployer  Plan. Neither such Borrower nor any ERISA Affiliate has failed to
make a required  installment or any other required  payment under Section 412 of
the IRC on or before the due date for such installment or other payment. Neither
such Borrower nor any ERISA Affiliate is required to provide  security to a Plan
under Section  401(a)(29) of the IRC due to a Plan  amendment that results in an
increase in current liability for the plan year.

     SECTION  8.02.  PRESERVATION  OF  COLLATERAL  AND  PERFECTION  OF  SECURITY
INTERESTS  THEREIN.  Such Borrower  shall execute and deliver to the  Collateral
Agent for the  benefit  of the  Agents  and the  Lenders,  prior to the  Initial
Funding  Date,  and at any  time  or  times  thereafter  at the  request  of the
Collateral  Agent or the Requisite  Lenders,  all financing  statements or other
documents  (and pay the  cost of  filing  or  recording  the same in all  public
offices deemed  necessary by the Collateral  Agent),  as the Collateral Agent or
the Requisite  Lenders may request,  in a form  satisfactory  to the  Collateral
Agent and the  Requisite  Lenders,  to perfect and keep  perfected  the security
interest in the Collateral  granted by such Borrower to the Collateral  Agent or
to otherwise  protect and preserve the  Collateral  and the  Collateral  Agent's
security interest therein or to enforce the Collateral Agent's security interest
in the Collateral.  Should such Borrower fail to do so, the Collateral  Agent is
authorized to sign any such financing  statements as such Borrower's agent. Such
Borrower  further agrees that a carbon,  photographic  or other  reproduction of
this  Agreement  or  of a  financing  statement  is  sufficient  as a  financing
statement.

     SECTION  8.03.  APPOINTMENT  OF THE  COLLATERAL  AGENT  AS  THE  BORROWERS'
ATTORNEY-IN-FACT.   Such  Borrower   hereby   irrevocably   designates,   makes,
constitutes and appoints the Collateral Agent (and all persons designated by the
Collateral  Agent) as its true and lawful  attorney-in-fact,  and authorizes the
Collateral  Agent,  in its or the  Collateral  Agent's name,  to,  following the
occurrence and during the continuance of an Event of Default: (i) demand payment
of the Borrower's Accounts;  (ii) enforce payment of such Borrower's Accounts by
legal  proceedings or otherwise;  (iii) exercise all such Borrower's  rights and
remedies with respect to proceedings brought to collect an Account; (iv) sell or
assign any Account upon such terms, for such amount and at such time or times as
the Collateral Agent deems advisable; (v) settle, adjust, compromise,  extend or
renew an Account;  (vi) discharge and release any Account;  (vii) prepare,  file
and sign  such  Borrower's  name on any  proof of claim in  bankruptcy  or other
similar document  against an account debtor of such Borrower;  (viii) notify the
post office  authorities  to change the address for delivery of such  Borrower's
mail to an address  designated by the Collateral  Agent,  and open and deal with
all mail  addressed  to the  Borrower;  (ix) do all acts and  things  which  are
necessary,  in the  Collateral  Agent's  discretion (as advised by the Requisite
Lenders), to fulfill such Borrower's obligations under this Agreement;  (x) take


                                       71
<PAGE>

control  in any manner of any item of payment  or  proceeds  thereof;  (xi) have
access  to any  lockbox  or  postal  box  into  which  such  Borrower's  mail is
deposited;  (xii)  endorse  such  Borrower's  name upon any items of  payment or
proceeds  thereof  and  deposit the same in the  Collateral  Agent's  account on
account of the Obligations; (xiii) endorse such Borrower's name upon any chattel
paper, document, instrument,  invoice, or similar document or agreement relating
to any Account or any goods pertaining  thereto;  and (xiv) sign such Borrower's
name on any verification of Accounts and notices thereof to account debtors.

     SECTION 8.04.  COLLECTION OF ACCOUNTS AND RESTRICTED ACCOUNT  ARRANGEMENTS.
Such  Borrower  hereby  represents  and warrants  that each  depository  account
("COLLECTION ACCOUNT") now maintained by it at any bank ("COLLECTION AGENT") for
the collection of checks and cash constituting proceeds of Accounts and sales of
other  personal  property  which are part of the  Collateral  is  identified  on
SCHEDULE  8.04  attached  hereto and made a part  hereof.  With  respect to each
Collection Account, such Borrower shall, no later than the Initial Funding Date,
deliver to the Collateral Agent, a "RESTRICTED ACCOUNT AGREEMENT"  substantially
in the form of EXHIBIT N attached  hereto and made a part hereof,  duly executed
and delivered by such Borrower and the applicable Collection Agent,  authorizing
and directing  such  Collection  Agent,  upon receipt of written notice from the
Collateral  Agent that an Event of Default has  occurred and is  continuing,  to
deposit all checks and cash  received into a restricted  account (a  "RESTRICTED
ACCOUNT")  and remit all amounts  deposited  in such  Restricted  Account to the
Collateral  Agent's account specified in such Restricted Account Agreement until
such time as the Collection  Agent  receives  written notice from the Collateral
Agent rescinding such instruction. Such Borrower shall, following the occurrence
and during the continuance of an Event of Default and any subsequent  request by
the Agent  therefor,  take such further  action as the  Collateral  Agent or the
Requisite  Lenders  may  reasonably  deem  desirable  to effect the  transfer of
exclusive  ownership and control of the  Restricted  Accounts and all Collection
Accounts  to  the  Collateral  Agent.   Until  all  the  Obligations  have  been
indefeasibly  paid in full, such Borrower agrees not to enter into any agreement
or execute and deliver any  direction  which would  modify,  impair or adversely
affect the rights and  benefits of the  Collateral  Agent  under any  Restricted
Account  Agreement.  Such  Borrower  shall not open,  establish  or maintain any
Collection Account (other than those identified on SCHEDULE 8.04 hereto) without
first having  delivered to the  Collateral  Agent a duly  executed and delivered
Restricted  Account  Agreement  with respect to such  Collection  Account.  Such
Borrower  shall  notify the  Collateral  Agent in writing not less than five (5)
days prior to the date it shall open or establish any  Collection  Account other
than an account described on SCHEDULE 8.04 hereto.

     SECTION  8.05.  CURE  RIGHTS.   Such  Borrower  expressly   authorizes  the
Collateral  Agent and the Agent,  and the  Collateral  Agent (as directed by the
Requisite  Lenders) and the Agent may, but shall not be required to, at any time
and from time to time, to take any and all action that it reasonably  determines
to be  necessary  or  desirable  to cure any default or  violation  (including a
payment  default) of such  Borrower in  connection  with any real estate  lease,
license agreement,  Governmental Approval or any other material lease, agreement
or contract entered into with respect to the Systems.

any other  event,  shall occur and shall  continue  after the  applicable  grace
period, if any,  specified in such agreement or instrument if the effect of such
default  or event is to  accelerate,  or to  permit  the  acceleration  of,  the
maturity of such indebtedness in excess of $250,000 with respect to any Borrower
or KMC IHC or in excess of $1,000,000 with respect to KMC Holdings;  or any such

required prepayment) prior to the stated maturity thereof; or

     (f) a  proceeding  under any  bankruptcy,  reorganization,  arrangement  of
debts,  insolvency or receivership law is filed by or against any Borrower,  KMC
Holdings  or KMC IHC,  or any  Borrower  or KMC  Holdings  takes  any  action to
authorize any of the foregoing  matters,  and in the case of any such proceeding
instituted against any Borrower,  KMC Holdings or KMC IHC (but not instituted by
any  Borrower,  KMC Holdings or KMC IHC),  either such  proceeding  shall remain
undismissed  or unstayed for a period of 60 days or any of the actions sought in
such proceeding (including, without limitation, the entry of an order for relief
against, or the appointment of a receiver, trustee or other similar official for
any Borrower,  KMC Holdings or KMC IHC or any substantial  part of its property)
shall be granted or shall occur; or

     (g) a Termination  Event occurs which the  Requisite  Lenders in good faith
believe would subject any Borrower to a material liability; or

     (h) the plan  administrator of any Plan applies under Section 412(d) of the
IRC for a waiver of the minimum  funding  standards of Section 412(a) of the IRC
and the Requisite Lenders in good faith believe that the approval of such waiver
could subject any Borrower or any ERISA Affiliate to material liability; or

Approval or other governmental  consent or approval necessary for the continuing
operation  of the  Borrower  or any  System or any other  material  Governmental
Approval or approval  of or material  filing with the FCC,  any PUC or any other
Governmental  Authority  with  respect  to the  conduct by any  Borrower  of its
business and operations,  including its Business, shall not be obtained or shall
cease  to be in  full  force  and  effect,  which  in  respect  of  any  of  the
Governmental  Approvals  shall,  in the case of an order of the FCC,  any PUC or
other Governmental Authority having jurisdiction with respect thereto, revoking,
or  deciding  not to  renew,  any such  Governmental  Approval,  occur  upon the

terminating  any of the  Governmental  Approvals  or deciding  not to renew such
Governmental  Approvals prior to the termination thereof,  occur when such order
becomes final, and, in each case, with respect to any such event occurring on or
after the  Trigger  Date,  such event is also  reasonably  likely to result in a
Material Adverse Effect; or



                                       74
<PAGE>

     (j) the FCC, any PUC or any other Governmental  Authority,  by final order,
determines that the existence or performance of this Agreement or any other Loan
Document   will  result  in  a  revocation,   suspension  or  material   adverse
modification  of any of the  Governmental  Approvals  for any  System,  and with
respect  to any such  event  occurring  on and  after  the  Trigger  Date,  such
determination is reasonably likely to result in a Material Adverse Effect; or

     (k) for any reason any Loan Document  shall not be in full force and effect
or shall not be  enforceable  in  accordance  with its  terms,  or any  security
interest or lien granted pursuant  thereto with respect to Collateral  having an

set aside adequate reserves in accordance with GAAP; or

     (m) for any reason,  any Borrower ceases to operate any System or ceases to
own any of its Governmental  Approvals necessary for the continuing operation of
any System, and with respect to any such event occurring on or after the Trigger
Date,  such  cessation  is  reasonably  likely to result in a  Material  Adverse
Effect; or

     (n) a judgment or judgments  for the payment of money in excess of $250,000
individually  or  $500,000  in the  aggregate  at any one time  shall  have been
rendered  against any Borrower and the same shall have remained  unsatisfied and

order of any court or  administrative  or regulatory  agency from conducting its

event is reasonably likely to result in a Material Adverse Effect; or

     (p) any  Borrower  becomes  subject to any  liabilities,  costs,  expenses,
damages,  fines or  penalties  which  could  reasonably  be  expected  to have a
Material  Adverse Effect arising out of or related to (i) any Remedial Action in
response to a Release or threatened  Release at any location of any  Contaminant
into the indoor or outdoor  environment  or (ii) any  material  violation of any

Borrower  fails to cure such breach  within ten (10) Business Days after written
notice thereof,  and with respect to any such failure  occurring on or after the
Trigger Date, such failure is reasonably  likely to result in a Material Adverse
Effect, unless such Borrower is contesting such covenant, condition or agreement
by appropriate protest or proceedings and shall have set aside adequate reserves
in accordance with GAAP.

     SECTION 9.02. TERMINATION OF COMMITMENT;  ACCELERATION. Upon the occurrence
and at any time during the continuance of any Event of Default,  the Agent shall
upon direction from the Requisite Lenders:

     (a) by notice to the Borrowers, terminate Lenders' Commitment to make Loans
hereunder; or

     (b) by notice to the Borrower,  declare the  Obligations  to be immediately
due and payable,  whereupon all the  Obligations  shall be  immediately  due and
payable  without  further  notice  of any  kind,  PROVIDED,  that if an Event of
Default  described in SECTION 9.01(F) shall exist or occur,  all the Obligations
shall  automatically,  without declaration or notice of any kind, be immediately
due and payable and the Commitment shall be automatically terminated.

     SECTION  9.03.  WAIVERS.  Demand,  presentment,   protest  and  notices  of

or  to  direct  the  application  of,  any  Collateral.   Each  Borrower  hereby
acknowledges  that none of the Collateral Agent, the Agent or any Lender has any
obligation  to resort to any  Collateral  or make claim against any other Person
before seeking payment or performance from any Borrower.



                                       76

     SECTION 9.04. RIGHTS AND REMEDIES GENERALLY.  If an Event of Default occurs
and is continuing, the Agent and the Collateral Agent shall have, in addition to
any other rights and remedies contained in this Agreement or in any of the other
Loan Documents, all the rights and remedies of a secured party under the Code or
other applicable  laws, which rights and remedies shall be cumulative,  and none
exclusive,  to the extent  permitted  by law. In addition to all such rights and
remedies,  the sale, lease or other  disposition of the Collateral,  or any part
thereof,  by the Collateral  Agent or the Agent after the occurrence of an Event
of  Default  may  be for  cash,  credit  or any  combination  thereof,  and  the
Collateral  Agent or the Agent may purchase all or any part of the Collateral at
public or, if permitted by law,  private sale,  and in lieu of actual payment of
such purchase  price,  may set off the amount of such purchase price against the
Obligations  then owing.  Any sales of the Collateral may be adjourned from time
to time with or without notice.  The Agent or the Collateral  Agent, may, in its
sole discretion, cause the Collateral to remain on the premises of any Borrower,
at the  expense  of the  Borrower,  pending  sale or  other  disposition  of the
Collateral.  The Agent or the  Collateral  Agent shall have the right to conduct
such sales on the premises of any Borrower, at the expense of the Borrowers,  or
elsewhere, on such occasion or occasions as it may see fit.

     SECTION 9.05. ENTRY UPON PREMISES AND ACCESS TO INFORMATION. If an Event of
Default occurs and is continuing,  the Agent and the Collateral Agent shall have
the right to enter upon the premises of any  Borrower  where any  Collateral  is
located (or is believed to be  located)  without any  obligation  to pay rent to
such Borrower,  or any other place or places where the Collateral is believed to
be located and kept, and render the Collateral unusable or remove the Collateral
therefrom to the premises of the Agent or the  Collateral  Agent or any agent of
the Agent or the Collateral  Agent, for such time as the Agent or the Collateral
Agent may desire,  in order  effectively to collect or liquidate the Collateral,
and/or the Agent or the  Collateral  Agent may require any  Borrower to assemble
the Collateral  and make it available to the Agent or the Collateral  Agent at a
place or places to be designated  by the Agent or the  Collateral  Agent.  If an
Event of Default  occurs and is continuing,  the Agent or the  Collateral  Agent
shall  have  the  right to  obtain  access  to any  Borrower's  data  processing
equipment,  computer hardware and software relating to the Collateral and to use
all of the foregoing  and the  information  contained  therein in any manner the
Agent or the Collateral Agent deems appropriate.

     SECTION 9.06.  SALE OR OTHER  DISPOSITION  OF COLLATERAL BY THE AGENT.  Any
notice  required  to be given by the  Agent or the  Collateral  Agent of a sale,
lease  or  other  disposition  or  other  intended  action  by the  Agent or the
Collateral Agent with respect to any of the Collateral which is deposited in the
United States mails, registered or certified, postage prepaid and duly addressed
to the Borrowers at the address  specified in SECTION  11.01,  at least ten days
prior to such proposed action shall constitute fair and reasonable notice to the
Borrowers  of any such  action.  The net  proceeds  realized by the Agent or the
Collateral  Agent upon any such sale or other  disposition,  after deduction for
the expense of retaking,  holding,  preparing for sale,  selling or the like and
the reasonable  attorneys' fees and legal expenses  incurred by the Agent or the
Collateral  Agent in connection  therewith,  shall be applied as provided herein
toward  satisfaction of the Obligations.  The Agent or the Collateral  Agent, as
applicable,  shall account to the  Borrowers for any surplus  realized upon such
sale or  other  disposition,  and the  Borrowers  shall  remain  liable  for any
deficiency. The commencement of any action, legal or equitable, or the rendering
of any  judgment or decree for any  deficiency  shall not affect the  Collateral
Agent's  security  interest  in the  Collateral.  The  Borrowers  agree that the


                                       77
<PAGE>

Collateral Agent has no obligation to preserve rights to the Collateral  against
any other  parties.  The Agent and the  Collateral  Agent are  hereby  granted a
license or other right to use, without charge, the Borrowers'  labels,  patents,
copyrights,  rights of use of any name, trade secrets, trade names,  trademarks,
service marks and advertising matter, or any property of a similar nature, as it
pertains to the Collateral, and the Borrowers' rights under all licenses and all
franchise  agreements  shall  inure to the Agent's  and the  Collateral  Agent's
benefit until the Obligations are paid in full.

     SECTION 9.07. GOVERNMENTAL APPROVALS. In connection with the enforcement by
the Agent or the Collateral Agent of any remedies available to it as a result of
any Event of Default,  each  Borrower  agrees  that it shall join and  cooperate
fully with, at the request of the Agent or the  Collateral  Agent,  any receiver
referred to below  and/or the  successful  bidder or bidders at any  foreclosure
sale in a filing of an application  (and  furnishing any additional  information
that may be required in connection with such application or which the Agent, the
Collateral  Agent  or  the  Requisite  Lenders  may  believe  relevant  to  such
application)  with  the  FCC,  any  PUC and all  other  applicable  Governmental
Authorities, requesting their prior approval of (i) the operation or abandonment
of all or the portion of any System  and/or (ii) the transfer of control of such
Borrower or assignment of all licenses,  certificates,  Governmental  Approvals,
approvals  and permits,  issued to each Borrower by the FCC, any PUC or any such
Governmental  Authorities with respect to any System and the operation  thereof,
to the Agent or the Collateral  Agent, the receiver or to the successful  bidder
or bidders.  In  connection  with the  foregoing,  the Borrower  shall take such
further actions, and execute all such instruments,  as the Agent, the Collateral
Agent or the Requisite  Lenders  reasonably  deems necessary or desirable.  Each
Borrower  agrees  that  the  Agent  or the  Collateral  Agent  may  enforce  any
obligation  of such  Borrower  as set forth in this  section  by an  action  for
specific performance.  In addition, each Borrower hereby irrevocably constitutes
and appoints the Agent and the Collateral Agent and any agent or officer thereof
(which  appointment  is  coupled  with  an  interest)  as its  true  and  lawful
attorney-in-fact  with full irrevocable power and authority and in the place and
stead of such Borrower and in the name of such Borrower or in its own name, from
time to time in its discretion  after the occurrence and during the  continuance
of an Event of Default and in connection with the foregoing,  for the purpose of
executing  on  behalf  and in  the  name  of the  Borrower  any  and  all of the
above-referenced  instruments  and to take  any and all  appropriate  action  in
furtherance of the foregoing.  THE EXERCISE OF ANY RIGHTS OR REMEDIES  HEREUNDER
OR UNDER ANY OTHER LOAN  DOCUMENT  BY ANY  LENDER,  THE AGENT OR THE  COLLATERAL
AGENT THAT MAY REQUIRE FCC, ANY PUC OR ANY OTHER GOVERNMENTAL AUTHORITY APPROVAL
SHALL BE SUBJECT TO OBTAINING SUCH APPROVAL. PENDING THE RECEIPT OF ANY FCC, ANY
PUC OR ANY OTHER GOVERNMENTAL  AUTHORITY APPROVAL, NO BORROWER SHALL DO ANYTHING
TO DELAY,  HINDER,  INTERFERE  OR  OBSTRUCT  THE  EXERCISE OF THE AGENT'S OR THE
COLLATERAL AGENT'S RIGHTS OR REMEDIES HEREUNDER IN OBTAINING SUCH APPROVALS.



                                       78
<PAGE>

     SECTION 9.08.  APPOINTMENT OF RECEIVER OR TRUSTEE.  In connection  with the
exercise of its remedies under this Agreement, the Agent or the Collateral Agent
may, upon the  occurrence of an Event of Default,  obtain the  appointment  of a
receiver or trustee to assume, upon receipt of all necessary judicial,  FCC, any
PUC or  other  Governmental  Authority  consents  or  approvals,  control  of or
ownership of any of the Governmental  Approvals.  Such receiver or trustee shall
have all rights and powers  provided  to it by law or by court order or provided
to the Agent or the Collateral Agent under this Agreement.  Upon the appointment
of such trustee or receiver,  the Borrowers  agree to  cooperate,  to the extent
necessary or appropriate,  in the expeditious preparation,  execution and filing
of an application to the FCC, any PUC or any other Governmental Authority or for
consent to the transfer of control or assignment of any Borrower's  Governmental
Approvals to the receiver or trustee.

     SECTION 9.09.  RIGHT OF SETOFF.  In addition to any rights now or hereafter
granted  under  applicable  law and not by way of limitation of any such rights,
upon the  occurrence and during the  continuance  of any Event of Default,  each
Lender and each holder of any Note is hereby authorized at any time or from time
to time,  without notice to any Borrower or to any other Person, any such notice
being hereby  expressly  waived,  to set off and to appropriate and to apply any
and  all  balances  held by it at any of its  offices  for  the  account  of any
Borrower (regardless of whether such balances are then due to such Borrower) and
any other  properties  or assets  any time held or owing by that  Lender or that
holder to or for the credit or for the  account of any  Borrower  against and on
account  of any of the  Obligations  which are not paid when due.  Any Lender or
holder of any Note  exercising  a right to set off or  otherwise  receiving  any
payment on account of the  Obligations  in excess of its Pro Rata Share  thereof
shall  purchase  for cash (and the other  Lenders  or holders  shall  sell) such
participation  in each such other  Lender's  or  holder's  Pro Rata Share of the
Obligations  as would be  necessary  to cause such Lender to share the amount so
set off or otherwise  received  with each other  Lender or holder in  accordance
with their  respective  Pro Rata Shares.  Each Borrower  agrees,  to the fullest
extent permitted by law, that (a) any Lender or holder may exercise its right to
set off  with  respect  to  amounts  in  excess  of its Pro  Rata  Share  of the
Obligations  and may  sell  participations  in such  amount  so set off to other
Lenders and holders and (b) any Lender or holder so  purchasing a  participation
in the Loans made or other  Obligations  held by other  Lenders  or holders  may
exercise all rights of set-off,  bankers' lien,  counterclaim  or similar rights
with respect to such  participation  as fully as if such Lender or holder were a
direct  holder  of the Loans and the  other  Obligations  in the  amount of such
participation.  Notwithstanding  the  foregoing,  if all or any  portion  of the
set-off amount or payment  otherwise  received is thereafter  recovered from the
Lender that has exercised the right of set-off,  the purchase of  participations
by that Lender  shall be  rescinded  and the  purchase  price  restored  without
interest. Each Borrower hereby agrees that the foregoing provisions are intended
to be construed so as to satisfy the  requirements of Section 553 of the Federal
Bankruptcy Code or amendments thereto (including any requirement of mutuality of
obligations therein).

                                    ARTICLE X
                       THE AGENT AND THE COLLATERAL AGENT

     SECTION 10.01. APPOINTMENT OF AGENT. (a) Lucent Technologies Inc. is hereby
appointed to act as  contractual  representative  on behalf of all Lenders under
this  Agreement  and the other Loan  Documents.  The Agent agrees to act as such
contractual representative upon the express conditions contained in this ARTICLE
X. The  provisions of this SECTION 10.01 are solely for the benefit of the Agent
and the Lenders and no Borrower or any other  Person  shall have any rights as a
third party  beneficiary  of any of the  provisions  hereof.  In performing  its
functions  and duties under this  Agreement  and the other Loan  Documents,  the
Agent  shall act solely as an agent of the Lenders and does not assume and shall
not be deemed to have assumed any obligation toward or relationship of agency or
trust with or for any  Borrower  or any other  Person.  The Agent  shall have no
duties  or  responsibilities  except  for  those  expressly  set  forth  in this
Agreement and the other Loan Documents.  Notwithstanding  the use of the defined
term  "Agent",  it is expressly  understood  and agreed that the Agent shall not
have any fiduciary  responsibilities  to any Lender by reason of this  Agreement
and that the Agent is merely  acting as the  representative  of the Lenders with
only those duties as are  expressly  set forth in this  Agreement  and the other
Loan Documents. In its capacity as the Lenders' contractual representative,  the
Agent (i) does not assume any fiduciary duties to any of the Lenders,  (ii) is a
"representative"  of the Lenders  within the meaning of Section 9-105 of the UCC
and (iii) is acting as an independent contractor, the rights and duties of which
are limited to those  expressly  set forth in this  Agreement and the other Loan
Documents.  Each of the Lenders  agrees to assert no claim  against the Agent on
any agency theory or any other theory of liability for breach of fiduciary duty,
all of which  claims  each  Lender  waives.  Neither  the  Agent  nor any of its
Affiliates nor any of their respective officers, directors, employees, agents or
representatives shall be liable to any Lender for any action taken or omitted to
be taken by it  hereunder  or under any other Loan  Document,  or in  connection
herewith  or  therewith,  except  for  damages  caused by its or their own gross
negligence or willful misconduct.

     (b) If the Agent shall  request  instructions  from all Lenders,  Requisite
Lenders or all affected  Lenders  with  respect to any act or action  (including
failure to act) in connection  with this  Agreement or any other Loan  Document,
then the Agent shall be entitled to refrain  from such act or taking such action
unless and until the Agent shall have  received  instructions  from all Lenders,
Requisite  Lenders,  or all affected Lenders,  as the case may be, and the Agent
shall not incur  liability to any Person by reason of so  refraining.  The Agent
shall be fully justified in failing or refusing to take any action  hereunder or
under any other Loan  Document (a) if such action  would,  in the opinion of the
Agent,  be  contrary  to law or the terms of this  Agreement  or any other  Loan
Document,  (b) if such action  would,  in the  opinion of the Agent,  expose the
Agent to  liabilities  beyond the limits of this  Agreement  or (c) if the Agent
shall not first be indemnified to its satisfaction against any and all liability
and expense  which may be incurred  by it by reason of taking or  continuing  to
take any such action.  Without limiting the foregoing,  no Lender shall have any
right of action whatsoever  against the Agent as a result of the Agent acting or
refraining from acting  hereunder or under any other Loan Document in accordance
with the instructions of all Lenders, Requisite Lenders or all affected Lenders,
as applicable.



                                       80

     SECTION  10.02.  AGENT'S  RELIANCE,  ETC.  Neither the Agent nor any of its
Affiliates nor any of their respective directors,  officers, agents or employees
shall be liable for any action  taken or omitted to be taken by it or them under
or in connection  with this  Agreement or the other Loan  Documents,  except for
damages  caused by its or their  own gross  negligence  or  willful  misconduct.
Without limitation of the generality of the foregoing,  the Agent: (a) may treat
the payee of any Note as the holder  thereof  until the Agent  receives  written
notice of the  assignment or transfer  thereof  signed by such payee and in form
satisfactory  to the Agent;  (b) may  consult  with legal  counsel,  independent
public  accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken in good faith by it in  accordance  with
the advice of such  counsel,  accountants  or experts;  (c) makes no warranty or
representation  to any Lender and shall not be responsible to any Lender for any
statements,  warranties or  representations  made in or in connection  with this
Agreement or the other Loan Documents;  (d) shall not have any duty to ascertain
or to inquire as to the performance or observance of any of the terms, covenants
or conditions of this  Agreement or the other Loan  Documents on the part of any
Borrower or to inspect the  Collateral  (including  the books and records);  (e)
shall  not be  responsible  to any  Lender  for  the  due  execution,  legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement or
the other Loan Documents or any other instrument or document  furnished pursuant
hereto or thereto;  and (f) shall incur no liability under or in respect of this
Agreement  or the other  Loan  Documents  by acting  upon any  notice,  consent,
certificate or other instrument or writing (which may be by telecopy,  telegram,
cable or telex)  believed  by it to be genuine  and signed or sent by the proper
party or parties.

     SECTION  10.03.  LUCENT AND  AFFILIATES.  With  respect to its  Commitments
hereunder, Lucent shall have the same rights and powers under this Agreement and
the other Loan Documents as any other Lender and may exercise the same as though
it were  not the  Agent;  and the  term  "Lender"  or  "Lenders"  shall,  unless
otherwise expressly indicated, include Lucent in its individual capacity. Lucent
and its  Affiliates  may lend money to, invest in, and  generally  engage in any
kind of business  with,  any Borrower,  any of its Affiliates and any Person who
may do business with or own  securities  of any Borrower or any such  Affiliate,
all as if Lucent were not the Agent and without any duty to account  therefor to
the Lenders.  Lucent and its Affiliates may accept fees and other  consideration
from any Borrower for services in  connection  with this  Agreement or otherwise
without  having to account for the same to Lenders.  Lucent may also purchase or
hold Equity  Interests or warrants in KMC Holdings,  KMC IHC or the Borrower and
make subordinated loans to any Borrower.  Each Lender acknowledges the potential
conflict  of  interest  between  Lucent  as a  Lender  holding  disproportionate
interests in the Loans,  Lucent as a member or  subordinated  debt holder of the
Borrower,  Lucent as a vendor under the Lucent Purchase  Agreement and Lucent as
Agent.

     SECTION 10.04.  LENDER CREDIT DECISION.  Each Lender  acknowledges  that it
has,  independently  and without reliance upon the Agent or any other Lender and
based on the  financial  information  given it by the  Borrowers  and such other
documents and information as it has deemed appropriate,  made its own credit and


                                       81
<PAGE>

financial  analysis  of the  Borrowers  and its own  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 deem  appropriate at the time,  continue to make its own
credit  decisions  in taking or not taking  action  under this  Agreement.  Each
Lender acknowledges the potential conflict of interest of each other Lender as a
result of Lenders holding disproportionate interests in the Loans, and expressly
consents to, and waives any claim based upon, such conflict of interest.

     SECTION 10.05. INDEMNIFICATION. Each of the Lenders agrees to indemnify the
Agent (to the extent not  reimbursed by the  Borrowers and without  limiting the
obligations of Borrowers  hereunder),  ratably according to their respective Pro
Rata  Shares,  from and against any and all  liabilities,  obligations,  losses,
damages, penalties,  actions, judgments, suits, costs, expenses or disbursements
of any kind or  nature  whatsoever  which may be  imposed  on,  incurred  by, or
asserted  against  the  Agent  in any way  relating  to or  arising  out of this
Agreement or any other Loan Document or any action taken or omitted by the Agent
in  connection  therewith;  PROVIDED,  that no Lender  shall be  liable  for any
portion of such liabilities,  obligations,  losses, damages, penalties, actions,
judgments,  suits, costs,  expenses or disbursements  resulting from the Agent's
gross negligence or willful  misconduct.  Without  limiting the foregoing,  each
Lender agrees to reimburse the Agent  promptly upon demand for its ratable share
of any out-of-pocket  expenses (including counsel fees) incurred by the Agent in
connection   with  the   preparation,   execution,   delivery,   administration,
modification,  amendment or enforcement  (whether  through  negotiations,  legal
proceedings  or  otherwise)  of,  or  legal  advice  in  respect  of  rights  or
responsibilities  under,  this  Agreement and each other Loan  Document,  to the
extent that the Agent is not reimbursed for such expenses by the Borrowers.

     SECTION 10.06.  SUCCESSOR AGENT. The Agent may resign at any time by giving
not less than thirty (30) days' prior written  notice thereof to Lenders and the
Borrowers. Upon any such resignation, the Requisite Lenders shall have the right
to appoint a successor Agent. If no successor Agent shall have been so appointed
by the Requisite Lenders and shall have accepted such appointment within 30 days
after the resigning  Agent's  giving notice of  resignation,  then the resigning
Agent may, on behalf of Lenders,  appoint a  successor  Agent,  which shall be a
Lender, if a Lender is willing to accept such appointment, or otherwise shall be
a commercial bank or financial  institution or a subsidiary of a commercial bank
or financial  institution if such  commercial  bank or financial  institution is
organized under the laws of the United States of America or of any State thereof
and has a combined capital and surplus of at least $300,000,000. If no successor
Agent has been appointed  pursuant to the  foregoing,  by the 30th day after the
date  such  notice  of  resignation  was  given  by the  resigning  Agent,  such
resignation  shall become  effective and the Requisite  Lenders shall thereafter
perform  all the  duties of Agent  hereunder  until such  time,  if any,  as the
Requisite  Lenders appoint a successor  Agent as provided  above.  Any successor
Agent  appointed  by the  Requisite  Lenders  hereunder  shall be subject to the
approval of Borrowers, such approval not to be unreasonably withheld or delayed;
PROVIDED  that such  approval  shall not be required if a Default or an Event of
Default  shall have  occurred  and be  continuing.  Upon the  acceptance  of any


                                       82
<PAGE>

appointment as Agent hereunder by a successor Agent,  such successor Agent shall
succeed to and become vested with all the rights, powers,  privileges and duties
of the resigning Agent. Upon the earlier of the acceptance of any appointment as
Agent  hereunder by a successor  Agent or the  effective  date of the  resigning
Agent's resignation, the resigning Agent shall be discharged from its duties and
obligations  under this Agreement and the other Loan Documents,  except that any
indemnity  rights  or  other  rights  in  favor of such  resigning  Agent  shall
continue.  After any resigning Agent's resignation hereunder,  the provisions of
this SECTION 10.06 shall inure to its benefit as to any actions taken or omitted
to be taken by it while it was Agent  under  this  Agreement  and the other Loan
Documents.

     SECTION  10.07.  PAYMENTS;  NON-FUNDING  LENDERS;  INFORMATION;  ACTIONS IN
CONCERT.

     (a) LOANS;  PAYMENTS.  Whenever the Agent  receives a payment of principal,
interest,  fee or premium (if any) or other payment, or whenever the Agent makes
an application of funds, in connection  with the Loans or the Notes  (including,
without limitation,  any payment or application from any Collateral),  the Agent
will on the date such  payment is received  or applied,  if on or prior to 11:00
a.m.  (Eastern  time) on such date,  or otherwise on the next  Business Day, pay
over to each Lender as instructed by such Lender in writing,  an amount equal to
such  Lender's  Pro Rata Share of such  payment  provided  that such  Lender has
funded all Loans  required to be made by it and has purchased all  participation
required to be purchased by it under this Agreement and the other Loan Documents
as of such date.  To the extent  that any Lender (a  "NON-FUNDING  LENDER")  has
failed to fund all such payments and Loans or failed to fund the purchase of all
such  participation,  the  Agent  shall  be  entitled  to set  off  the  funding
short-fall  against  that  Non-Funding  Lender's  Pro Rata Share of all payments
received  from  the  Borrowers.  All  payments  by  Agent  shall be made by wire
transfer to such  Lender's  account (as specified by such Lender) not later than
2:00 p.m. (Eastern time) on the applicable Business Day.

     (b) RETURN OF PAYMENTS.  (i) If Agent pays an amount to a Lender under this
Agreement in the belief or expectation  that a related  payment has been or will
be  received by the Agent from the  Borrowers  and such  related  payment is not
received by Agent,  then the Agent will be entitled to recover  such amount from
such Lender on demand without set-off, counterclaim or deduction of any kind.

          (ii) If the Agent  determines at any time that any amount  received by
     the Agent under this  Agreement must be returned to any Borrower or paid to
     any  other  Person  pursuant  to any  insolvency  law or  otherwise,  then,
     notwithstanding  any other term or condition of this Agreement or any other
     Loan  Document,  the Agent will not be required to  distribute  any portion
     thereof to any  Lender.  In  addition,  each  Lender will repay to Agent on
     demand any portion of such amount  that the Agent has  distributed  to such
     Lender,  together  with  interest  at such  rate,  if any,  as the Agent is
     required to pay to any  Borrower  or such other  Person,  without  set-off,
     counterclaim or deduction of any kind.



                                       83
<PAGE>

     (c) NON-FUNDING  LENDERS. The failure of any Non-Funding Lender to make any
portion  of its  Loans  or any  payment  required  by it  hereunder  on the date
specified  therefor  shall not relieve any other Lender (each such other Lender,
an "OTHER  LENDER") of its  obligations  to make any such Loan on such date, but
neither any Other Lender nor the Agent shall be  responsible  for the failure of
any  Non-Funding  Lender to make any Loan.  Notwithstanding  anything  set forth
herein to the  contrary,  a  Non-Funding  Lender  shall  not have any  voting or
consent  rights  under or with  respect to any Loan  Document  or  constitute  a
"Lender" (or be included in the calculation of "Requisite Lenders" or "Requisite
Revolving  Lenders"  hereunder)  for any voting or consent  rights under or with
respect to any Loan Document.

     (d) DISSEMINATION OF INFORMATION.  The Agent will use reasonable efforts to
provide  Lenders with any notice of Default or Event of Default  received by the
Agent from,  or  delivered  by the Agent to, the  Borrowers,  with notice of any
Event of Default of which the Agent has actually become aware and with notice of
any action taken by the Agent following any Event of Default;  PROVIDED that the
Agent shall not be liable to any Lender for any failure to do so,  except to the
extent that such failure is  attributable  to the Agent's  gross  negligence  or
willful  misconduct.  Lenders  acknowledge  that the  Borrowers  are required to
provide  financial  statements and other  documents to Lenders  pursuant to this
Agreement  and agree that the Agent  shall  have no duty to provide  the same to
Lenders.

     (e)  ACTIONS  IN  CONCERT.  Anything  in  this  Agreement  to the  contrary
notwithstanding, each Lender hereby agrees with each other Lender that no Lender
shall  take any action to protect  or  enforce  its rights  arising  out of this
Agreement  or the Notes  (including  exercising  any rights of set-off)  without
first obtaining the prior written consent of the Agent and Requisite Lenders, it
being the intent of Lenders  that any such  action to protect or enforce  rights
under  this  Agreement  and the  Notes  shall  be taken  in  concert  and at the
direction or with the consent of Agent.

     SECTION 10.08. COLLATERAL MATTERS.

     (a)  The  Collateral  Agent,  at the  written  direction  of the  Requisite
Lenders,  may release any Lien upon any Collateral  (i) upon the  termination of
the  Commitments  and  payment  and  satisfaction  of all  Loans  and all  other
Obligations  and which the Agent has been  notified  in writing are then due and
payable;  (ii) constituting property being sold or disposed of if the applicable
Borrower  certifies to the Collateral Agent that the sale or disposition is made
in compliance with SECTION 6.03 (and the Agent may rely conclusively on any such
certificate,  without further inquiry); or (iii) constituting property leased to
the applicable  Borrower under a lease which has expired or been terminated in a
transaction  permitted under this Agreement or which will expire  imminently and
which has not been,  and is not  intended  by such  Borrower  to be,  renewed or
extended and with respect to which such  Borrower has not exercised any purchase
option.  The  Collateral  Agent may not  release  all or  substantially  all the
Collateral  without the consent of the Lenders.  Upon request by the  Collateral


                                       84
<PAGE>

Agent or the  Borrowers  at any time,  the Lenders  will  confirm in writing the
Collateral  Agent's  authority  to release any Liens  pursuant  to this  SECTION
10.08(A).

     (b) Upon  receipt by the  Collateral  Agent of any  authorization  required
pursuant  to  SECTION  10.08(A)  from  the  Requisite  Lenders  or  Lenders,  as
applicable,  of the  Collateral  Agent's  authority  to  release  any Liens upon
particular  types or items of  Collateral,  and upon at least five (5)  Business
Days' prior written  request by the  applicable  Borrower,  and provided that no
Event of Default has occurred and is then continuing, the Collateral Agent shall
(and is hereby irrevocably  authorized by the Lenders to) execute such documents
as may be necessary  to evidence the release of the Liens upon such  Collateral;
PROVIDED,  that (i) the  Collateral  Agent  shall not be required to execute any
such document on terms which, in the Collateral  Agent's  opinion,  would expose
the  Collateral  Agent to  liability  or create  any  obligation  or entail  any
consequence  other than the release of such Liens without  recourse or warranty,
and (ii) such release  shall not in any manner  discharge,  affect or impair the
Obligations or any Liens (other than those  expressly  being  released) upon (or
obligations of the applicable  Borrower in respect of) all interests retained by
the applicable  Borrower,  including  (without  limitation)  the proceeds of any
sale, all of which shall continue to constitute part of the Collateral.

     (c) The Collateral Agent shall have no obligation  whatsoever to any of the
Lenders to assure that the  Collateral  exists or is owned by any Borrower or is
cared for, protected or insured or has been encumbered, or, other than a duty to
act without recklessness, willful misconduct or gross (but not mere) negligence,
that  the  Liens  have  been  properly  or  sufficiently  or  lawfully  created,
perfected,  protected or enforced or are entitled to any particular priority, or
to  exercise  at all or in any  particular  manner  or  under  any duty of care,
disclosure  or  fidelity,  or  to  continue  exercising,   any  of  the  rights,
authorities  and powers  granted or  available  to the  pursuant to this SECTION
10.08 or pursuant to any of the Loan Documents,  it being  understood and agreed
that in  respect  of the  Collateral,  or any act,  omission  or  event  related
thereto, the Collateral Agent may act in any manner it may deem appropriate,  in
its reasonable  business judgment,  given the Collateral Agent's own interest in
the  Collateral  in its  capacity as one of the Lenders and that the  Collateral
Agent shall have no other duty or liability  whatsoever  to any Lender as to any
of the foregoing.

     SECTION  10.09.  AGENCY FOR  PERFECTION.  Each Lender hereby  appoints each
other  Lender as agent for the  purpose  of  perfecting  the  Lenders'  security
interest  in  assets  which,  in  accordance  with  Article  9 of the UCC can be
perfected  only by  possession.  Should any Lender  (other  than the  Collateral
Agent) obtain  possession of any such  Collateral,  such Lender shall notify the
Collateral  Agent thereof,  and,  promptly upon the Collateral  Agent's  request
therefor shall deliver such Collateral to the Collateral Agent.

     SECTION 10.10. CONCERNING THE COLLATERAL AND THE RELATED LOAN DOCUMENTS AND
THE  COLLATERAL  AGENT.  (a) Each Lender  authorizes  and directs the Collateral
Agent to enter into this Agreement and the other Loan Documents  relating to the
Collateral,  for  the  ratable  benefit  of the  Lenders.  The  exercise  by the
Collateral Agent or the Requisite  Lenders of their respective  powers set forth


                                       85
<PAGE>

in this  Agreement  or the other  Loan  Documents  relating  to the  Collateral,
together with such other powers that are reasonably incidental thereto, shall be
binding upon all of the Lenders;  PROVIDED that the  Collateral  Agent shall not
without the consent of the Requisite  Lenders take any action in accordance with
the  terms  of this  Agreement  or the  other  Loan  Documents  relating  to the
Collateral (other than, in the exercise of its reasonable  judgment,  actions to
preserve the value of the Collateral).

     (b)  The  Collateral  Agent  with  respect  to  the  administration  of the
Collateral  shall have the same rights,  obligations  and status as the Agent as
are set forth in SECTION 10.01, 10.02, 10.03, 10.04, 10.05, and 10.06 above.


                                   ARTICLE XI

Agent or the Collateral  Agent may consult with legal  counsel,  selected by the

     SECTION  11.02.  NO  WAIVERS;  AMENDMENTS.  (a) No  failure or delay of the
Agent,  the  Collateral  Agent or any Lender to exercise any right  hereunder or
under any other Loan Document shall operate as a waiver  thereof,  nor shall any
single or partial  exercise  of any such  right,  preclude  any other or further
exercise  thereof or the exercise of any other right. No waiver of any provision
of this Agreement or any other Loan Document nor consent to any departure by any
Borrower  therefrom shall in any event be effective  unless the same shall be in
writing and signed by the Agent and the Requisite Lenders,  and then such waiver
or consent shall be effective only in the specific  instance and for the purpose
for which given.  No notice or demand on any Borrower in any case shall  entitle
any  Borrower  to any other or  further  notice or  demand in  similar  or other
circumstances.

     (b) Subject to the  provisions  of this  SECTION  11.02(B),  the  Requisite
Lenders (or the Agent with the consent in writing of the Requisite  Lenders) and
the Borrowers may enter into agreements  supplemental  hereto for the purpose of
adding or  modifying  any  provisions  to the Loan  Documents or changing in any
manner the rights of the Lenders or the Borrowers hereunder or waiving any Event
of Default or Default  hereunder;  PROVIDED that no such supplemental  agreement
shall,  without the consent of each Lender  affected  thereby and in the case of
clause (vii) below,  so long as Lucent shall have any unused  Commitment  Amount
without the consent of Lucent:

          (i) Postpone or extend the Commitment  Termination  Date, the maturity
     date for the loans or any other date fixed for any payment of principal of,
     or  interest  on,  the Loans or any fees or other  amounts  payable to such
     Lender  except  with  respect to (A) any  modifications  of the  provisions
     relating to prepayments of Loans and other  Obligations and (B) a waiver of
     the  application  of the  default  rate of  interest  pursuant  to  SECTION
     2.05(B).

          (ii) Reduce the principal  amount of any Loans,  or reduce the rate or
     extend the time of payment of interest or fees thereon.

          (iii) Reduce the  percentage  specified in the definition of Requisite
     Lenders or any other  percentage of Lenders  specified to be the applicable
     percentage  in this  Agreement  to act on  specified  matters  or amend the

No amendment of any  provision  of this  Agreement  relating to the Agent or the
Collateral Agent shall be effective  without the written consent of the Agent or
the Collateral Agent, as applicable.

     SECTION 11.03. GOVERNING LAW AND JURISDICTION. THIS AGREEMENT AND THE OTHER
LOAN  DOCUMENTS  SHALL BE  CONSTRUED  IN  ACCORDANCE  WITH AND  GOVERNED  BY THE
INTERNAL LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO ANY CONFLICTS OF
LAWS PRINCIPLES.  THE BORROWERS, THE AGENT, THE COLLATERAL AGENT AND THE LENDERS
CONSENT TO THE JURISDICTION OF ANY LOCAL,  STATE OR FEDERAL COURT LOCATED IN THE
CITY AND STATE OF NEW YORK AND WAIVE ANY OBJECTION RELATING TO IMPROPER VENUE OR
FORUM NON CONVENIENCE TO THE CONDUCT OF ANY PROCEEDING BY SUCH COURT.

            SECTION  11.04.  EXPENSES.  The  Borrowers  will pay all  documented
out-of-pocket  third-party  expenses  (including  in each  case  all  reasonable
attorneys' and paralegals' fees and related expenses and costs), (i) incurred by
the  Agent  and  the  Collateral  Agent  in  connection  with  the  negotiation,
preparation and execution of the Loan Documents (whether or not the transactions
contemplated  hereby  shall be  consummated),  (ii)  incurred by the Agents,  in
connection  with the  administration  of the Loan  Documents,  and the creation,
perfection,  priority and protection of the Liens in the  Collateral,  and (iii)
incurred by the Agent, the Collateral Agent or any Lender in connection with the
enforcement of the rights of the Agent,  the  Collateral  Agent or any Lender in
connection with this Agreement,  any other Loan Documents or the Collateral,  or
any restructuring or workout of this Agreement or the other Loan Documents.

            SECTION 11.05.  EQUITABLE RELIEF.  Each Borrower recognizes that, in
the event it fails to perform,  observe or discharge any of its  obligations  or
liabilities under this Agreement,  or any other Loan Document, any remedy at law
may prove to be inadequate  relief to the Agent,  the  Collateral  Agent and the
Lenders; therefore, such Borrower agrees that the Agent or the Collateral Agent,
if it so  requests,  shall be entitled to  temporary  and  permanent  injunctive
relief in any such case without the necessity of proving actual damages.

     SECTION 11.06. INDEMNIFICATION;  LIMITATION OF LIABILITY. (a) The Borrowers
agree to protect,  indemnify and hold harmless the Agent,  the Collateral  Agent
each  Lender  and  each of their  respective  officers,  affiliates,  directors,
employees,  attorneys,  accountants,  consultants,  representatives  and  agents
(collectively   called  the   "Indemnitees")   from  and  against  any  and  all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
claims,  costs,  expenses  and  disbursements  (including,  without  limitation,
payment by the Agent,  the Collateral Agent or any Lender of any obligations due
or past due under any  contract or agreement to which any Borrower is or becomes
a party) of any kind or nature whatsoever  (including,  without limitation,  the


                                       88
<PAGE>

fees and  disbursements  of counsel for and  consultants of such  Indemnitees in
connection  with  any  investigative,  administrative  or  judicial  proceeding,
whether or not such Indemnitees shall be designated a party thereto),  which may
be imposed  on,  incurred  by, or asserted  against  such  Indemnitees  (whether
direct,  indirect,  or  consequential  and whether based on any federal or state
laws or other statutory regulations,  including, without limitation, securities,
environmental  and  commercial  laws and  regulations,  under  common  law or at
equitable  cause or on  contract  or  otherwise)  in any manner  relating  to or
arising out of this  Agreement or any of the other Loan  Documents,  or any act,
event or transaction related or attendant thereto,  the agreements of the Agent,
the Collateral Agent or the Lenders contained  herein,  the making of Loans, the
management  of such  Loans or the  Collateral  (including  any  liability  under
Environmental  Laws) or the use or  intended  use of the  proceeds of such Loans
hereunder (collectively,  the "INDEMNIFIED MATTERS");  PROVIDED that no Borrower
shall  have  any  obligation  to  any  Indemnitee   hereunder  with  respect  to
Indemnified  Matters caused by or resulting from the willful misconduct or gross
negligence of such  Indemnitee;  PROVIDED,  FURTHER that the Borrowers shall not
have any obligation to any  Indemnitee  hereunder with respect to taxes that are
imposed on the net income of any  Indemnitee or any franchise or doing  business
taxes  imposed  on any  Indemnitee.  To  the  extent  that  the  undertaking  to
indemnify,  pay and hold  harmless  set forth in the  preceding  sentence may be
unenforceable because it is violative of any law or public policy, the Borrowers
shall contribute the maximum portion which they are permitted to pay and satisfy
under applicable law, to the payment and satisfaction of all Indemnified Matters
incurred by the Indemnitees.

     (b) To the extent  permitted by applicable law, no claim may be made by the
Borrowers or any other  Person  against the Agent,  the  Collateral  Agent,  any
Lender or any of their respective affiliates,  directors,  officers,  employees,
agents, attorneys, accountants,  representatives or consultants for any special,
indirect,  consequential  or punitive damages in respect of any claim for breach
of contract or any other  theory of  liability  arising out of or related to the
transactions  contemplated by any of the Loan Documents or any act,  omission or
event occurring in connection therewith; and the Borrowers hereby waive, release
and agree not to sue upon any claim for any such damages, whether or not accrued
and whether or not known or suspected to exist in its favor.

     SECTION  11.07.  SURVIVAL  OF  REPRESENTATIONS  AND  WARRANTIES,  ETC.  All
warranties and  representations  made by any Borrower in any Loan Document shall
survive  the  execution  and  delivery  of this  Agreement  and the  other  Loan
Documents and the making and repayment of the Obligations.  The  confidentiality
obligations of each Borrower in SECTION 11.16, the  indemnification  obligations
of each  Borrower  in SECTION  11.06,  and to the extent the second  sentence of
SECTION  11.13 is  applicable,  all  covenants  of each  Borrower,  survive  the
repayment of the Obligations.

     SECTION 11.08. SUCCESSORS AND ASSIGNS; ASSIGNMENTS; PARTICIPATIONS.

     (a)  GENERAL.  The  terms and  provisions  of the Loan  Documents  shall be
binding  upon  and  inure  to the  benefit  of the  Borrowers,  the  Agent,  the
Collateral  Agent and the Lenders and their  respective  successors and assigns,
except  that (i) no  Borrower  shall  have any  right to  assign  its  rights or


                                       89
<PAGE>

obligations  under the Loan Documents and (ii) any assignment by any Lender must
be made in compliance with  SUBSECTION (C) below.  With respect to any Borrower,
successors and assigns shall include, without limitation,  any receiver, trustee
or debtor-in-possession of or for such Borrower.  Notwithstanding the foregoing,
any Lender may at any time,  without the consent of the  Borrowers or the Agent,
assign all or any portion of its rights under this  Agreement and its Notes to a
Federal  Reserve Bank or to an affiliate of such Lender;  PROVIDED  that no such
assignment shall release the transferor  Lender from its obligations  hereunder.
The Agent shall be entitled to utilize its  Register to  determine  the payee of
any Note for all  purposes  hereof.  Any  request,  authority  or consent of any
Person,  who at the time of making  such  request or giving  such  authority  or
consent  is the  holder of any Note,  shall be  conclusive  and  binding  on any
subsequent  holder,  transferee or assignee of such Note or of any Note or Notes
issued in exchange therefor.

     (b) PARTICIPATIONS.

          (i)  Subject  to the  terms set forth in this  SECTION  11.08(B),  any
     Lender may, in the ordinary  course of its business and in accordance  with
     applicable  law,  at any time sell to one or more  banks or other  entities
     ("PARTICIPANTS")  participating interests in any Loan owing to such Lender,
     any Note held by such Lender,  any  Commitment  of such Lender or any other
     interest of such Lender  under the Loan  Documents on a pro rata or non-pro
     rata  basis.  Notice of such  participation  to the Agent shall be required
     prior to any participation becoming effective with respect to a Participant
     which is not a Lender  or an  Affiliate  thereof.  In the event of any such
     sale by a Lender of participating interests to a Participant, such Lender's
     obligations  under the Loan Documents shall remain  unchanged,  such Lender
     shall  remain  solely  responsible  to the  other  parties  hereto  for the
     performance of such obligations, such Lender shall remain the holder of any
     such Note for all purposes under the Loan  Documents,  such Lender shall be
     solely  responsible  for any  withholding  taxes or any filing or reporting
     requirements  in connection  therewith  relating to such  Participant,  all
     amounts  payable by the Borrowers  under this Agreement shall be determined
     as if such  Lender  had not  sold  such  participating  interests,  and the
     Borrowers  and the Agent shall  continue to deal solely and  directly  with
     such Lender in connection with such Lender's  rights and obligations  under
     the  Loan  Documents  except  that,  for  purposes  of  SECTION  2.13,  the
     Participants  shall be entitled to the same rights as if they were Lenders,
     PROVIDED  that no  Participant  shall be  entitled  to receive  any greater
     amount  pursuant to SECTION 2.13 than such Lender would have been  entitled
     to receive in respect  of the amount of the  participation  transferred  to
     such Participant had no transfer occurred.

          (ii) Each Lender shall  retain the sole right to approve,  without the
     consent of any  Participant,  any amendment,  modification or waiver of any
     provision of the Loan Documents  other than any amendment,  modification or
     waiver with respect to any Loan or Commitment in which such Participant has
     an  interest  which  forgives  principal,  interest  or fees or reduces the


                                       90
<PAGE>

     interest rate or fees payable  pursuant to the terms of this Agreement with
     respect to any such Loan or  Commitment,  postpones  any date fixed for any
     regularly-scheduled  payment of  principal  of, or interest or fees on, any
     such  Loan  or  Commitment,  or  releases  all  or  substantially  all  the
     Collateral,  if any, securing any such Loan. 

          (iii) The  Borrowers  agree that each  Participant  shall be deemed to
     have the  right of  setoff  provided  in  SECTION  9.09 in  respect  to its
     participating  interest in amounts  owing under the Loan  Documents  to the
     same  extent as if the  amount of its  participating  interest  were  owing
     directly to it as a Lender  under the Loan  Documents;  PROVIDED  that each
     Lender  shall  retain the right of setoff  provided  in  SECTION  9.09 with
     respect to the amount of  participating  interests sold to each Participant
     except to the extent such  Participant  exercises its right of setoff.  The
     Lenders  agree to share with each  Participant,  and each  Participant,  by
     exercising  the right of setoff  provided in SECTION 9.09,  agrees to share
     with each Lender, any amount received pursuant to the exercise of its right
     of setoff,  such amounts to be shared in accordance with SECTION 9.09 as if
     each Participant were a Lender.

     (c) ASSIGNMENTS.

          (i) Any Lender  may, in the  ordinary  course of its  business  and in
     accordance  with applicable law, at any time assign to one or more banks or
     other  entities   ("PURCHASERS")  all  or  a  portion  of  its  rights  and
     obligations  under  this  Agreement  (including,  without  limitation,  its
     Commitment  and the Loans owing to it  hereunder)  in  accordance  with the
     provisions  of  this  SECTION  11.08(C).  Each  assignment  shall  be  of a
     constant,  and not a varying,  ratable  percentage  of all of the assigning
     Lender's rights and obligations under this Agreement. Such assignment shall
     be evidenced by an Assignment  Agreement in form and  substance  reasonably
     satisfactory to the Agent and shall not be permitted  hereunder unless such
     assignment is either for all of such Lender's rights and obligations  under
     the Loan Documents or, for Loans and Commitments in an aggregate  principal
     amount  equal to the  lesser of  $5,000,000  (which  minimum  amount may be
     waived by the Requisite Lenders after the occurrence of a Default) and such
     Lender's Commitment Amount.

          (ii)  Upon (i)  delivery  to the Agent of a notice  of  assignment  (a
     "NOTICE OF ASSIGNMENT"),  together with any consent required hereunder, and
     (ii) payment of a $3,500  processing fee to the Agent for  processing  such
     assignment  if such  assignment is to a Person which is not an affiliate of
     the  assigning  Lender,  such  assignment  shall  become  effective  on the
     effective date specified in such Notice of Assignment. The assigning Lender
     shall be obligated to reimburse  the Agent for all other costs and expenses
     associated with the preparation and execution of such assignment (including
     reasonable attorneys' fees arising out of such preparation and execution of
     such  assignment).  The Notice of Assignment shall contain a representation
     by the Purchaser to the effect that none of the consideration  used to make
     the purchase of the Commitment  and Loans under the  applicable  assignment
     agreement  are "plan assets" as defined under ERISA and that the rights and
     interests  of the  Purchaser  in and under the Loan  Documents  will not be


                                       91
<PAGE>

     "plan  assets"  under  ERISA.  On and  after  the  effective  date  of such
     assignment, such Purchaser, if not already a Lender, shall for all purposes
     be a Lender party to this Agreement and any other Loan  Documents  executed
     by the  Lenders and shall have all the rights and  obligations  of a Lender
     under the Loan  Documents,  to the same  extent  as if it were an  original
     party  hereto,  and no  further  consent  or action by the  Borrowers,  the
     Lenders or the Agent shall be required  to release  the  transferor  Lender
     with  respect  to the  percentage  of the  aggregate  Commitment  and Loans
     assigned to such  Purchaser.  Upon the  consummation of any assignment to a
     Purchaser pursuant to this SECTION 11.08(C)(II), the transferor Lender, the
     Agent  and  the  Borrowers  shall  make  appropriate  arrangements  so that
     replacement Notes are issued to such transferor Lender and new Notes or, as
     appropriate,  replacement Notes, are issued to such Purchaser, in each case
     in principal  amounts  reflecting  their  Commitment  and their  Loans,  as
     adjusted pursuant to such assignment.

          (iii) The Agent shall  maintain at its address  referred to in SECTION
     11.01 a copy of each assignment delivered to and accepted by it pursuant to
     this SECTION 11.08 and a register (the  "REGISTER")  for the recordation of
     the names and addresses of the Lenders and the  Commitment of and principal
     amount of the Loans  owing to,  each  Lender  from time to time and whether
     such  Lender  is an  original  Lender or the  assignee  of  another  Lender
     pursuant to an  assignment  under this  SECTION  11.08.  The entries in the
     Register shall be conclusive and binding for all purposes,  absent manifest
     error,  and the Borrowers,  the Agent and the Lenders may treat each Person
     whose  name is  recorded  in the  Register  as a Lender  hereunder  for all
     purposes of this Agreement.  The Register shall be available for inspection
     by the Borrowers or any Lender at any reasonable time and from time to time
     upon reasonable prior notice.

     SECTION  11.09.  SEVERABILITY.  In case  any one or more of the  provisions
contained in this Agreement or any other Loan Document shall be invalid, illegal
or unenforceable in any respect,  the validity,  legality and  enforceability of
the remaining  provisions  contained  herein and therein shall not in any way be
affected or impaired thereby.

     SECTION  11.10.  COVER PAGE,  TABLE OF CONTENTS AND SECTION  HEADINGS.  The
cover  page,  Table  of  Contents  and  section  headings  used  herein  are for
convenience  of reference  only,  are not part of this  Agreement and are not to
affect the construction of or be taken into  consideration in interpreting  this
Agreement.

     SECTION 11.11.  COUNTERPARTS.  This Agreement may be signed in counterparts
with the same effect as if the signatures  thereof and hereto were upon the same
instrument.

     SECTION  11.12.  APPLICATION  OF  PAYMENTS.  Notwithstanding  any  contrary
provision  contained in this  Agreement  or in any of the other Loan  Documents,
upon the  occurrence and during the  continuance  of any Event of Default,  each
Borrower  irrevocably  waives the right to direct the application of any and all
payments at any time or times hereafter received by the Agent or any Lender from


                                       92
<PAGE>

such Borrower or with respect to any of the  Collateral,  and such Borrower does
hereby  irrevocably agree that the Agent or any Lender shall have the continuing
exclusive  right to apply and reapply any and all payments  received at any time
or times hereafter, whether with respect to the Collateral or otherwise, against
the  Obligations  in such manner as the Agent or any Lender may deem  advisable,
notwithstanding  any entry by the Agent or any Lender  upon any of its books and
records, subject, however, to the provisions of SECTION 2.08(C).

     SECTION 11.13.  MARSHALLING;  PAYMENTS SET ASIDE. Neither the Agent nor the
Agent  shall be under any  obligation  to  marshall  any  assets in favor of any
Borrowers  or the other  party or  against  or in  payment  of any or all of the
Obligations.  To the extent that any Borrower makes a payment or payments to any
Agent or any Lender,  or the Agent, the Collateral Agent any Lender enforces its
security  interests  or  exercises  its  rights of setoff,  and such  payment or
payments or the proceeds of such  enforcement  or setoff or any part thereof are
subsequently invalidated,  declared to be fraudulent or preferential,  set aside
and/or required to be repaid to a trustee, receiver or any other party under any
bankruptcy law, state or federal law, common law or equitable cause, then to the
extent of such recovery,  the obligation or part thereof originally  intended to
be satisfied  shall be revived and continued in full force and effect as if such
payment had not been made or such enforcement or setoff had not occurred.

     SECTION 11.14. SERVICE OF PROCESS. EACH BORROWER WAIVES PERSONAL SERVICE OF
ANY PROCESS UPON IT AND,  CONSENTS  THAT ALL SERVICE OF PROCESS SHALL BE MADE BY
REGISTERED  MAIL,  RETURN  RECEIPT  REQUESTED,  DIRECTED TO EACH BORROWER AT THE
ADDRESS  INDICATED  IN SECTION  11.01 AND  SERVICE SO MADE SHALL BE DEEMED TO BE
COMPLETED FIVE (5) BUSINESS DAYS AFTER SAME SHALL HAVE BEEN POSTED AS AFORESAID.

     SECTION 11.15. WAIVER OF JURY TRIAL, ETC. EACH OF THE BORROWERS, THE AGENT,
THE COLLATERAL AGENT AND THE LENDERS WAIVES ANY RIGHT TO HAVE A JURY PARTICIPATE
IN RESOLVING  ANY DISPUTE,  WHETHER  SOUNDING IN CONTRACT,  TORT,  OR OTHERWISE,
BETWEEN THE AGENT,  THE COLLATERAL  AGENT OR ANY LENDER AND ANY BORROWER ARISING
OUT OF, CONNECTED WITH, RELATED TO OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED
BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY
OTHER  INSTRUMENT,  DOCUMENT OR AGREEMENT  EXECUTED OR  DELIVERED IN  CONNECTION
THEREWITH OR THE TRANSACTIONS RELATED THERETO. EACH OF THE BORROWERS, THE AGENT,
THE  COLLATERAL  AGENT AND THE LENDERS  HEREBY AGREES AND CONSENTS THAT ANY SUCH
CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT
A JURY AND THAT ANY OF THEM  MAY FILE AS AN  ORIGINAL  COUNTERPART  OR A COPY OF
THIS AGREEMENT WITH ANY COURT AS WRITTEN  EVIDENCE OF THE CONSENT OF THE PARTIES
HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.



                                       93
<PAGE>

     SECTION  11.16.  CONFIDENTIALITY.  No Borrower  shall at any time before or
after  payment  in full  and  satisfaction  of all of the  Obligations,  reveal,
divulge or make known, or knowingly  permit to be so revealed,  divulged or made
known, to any Person  (including  Persons within its own organization who do not
have a definite need to know for the purpose of performance of this  Agreement),
the terms or conditions of the Fee Letter; PROVIDED that the foregoing shall not
apply to  information  required to be disclosed by order of a court of competent
jurisdiction or in connection with any governmental  investigation (in each case
to the extent  disclosure is required,  but no further) so long as such Borrower
notifies  the Agent in writing of any  circumstances  of which such  Borrower is
aware that may lead to such a requirement or order,  so as to allow the Agent to
take steps to contest such order or investigation;  PROVIDED,  FURTHER, that the
foregoing  shall not apply to  information  which is required to be disclosed by
such  Borrower or  information  which in the  reasonable  determination  of such
Borrower  is  desirable  for  it to  disclose,  pursuant  to  federal  or  state
securities  laws,  pursuant to the rules or  regulations  of the FCC, any PUC or
other  applicable  Governmental  Authority,  or to Persons who are  consultants,
advisors  (including  but not  limited to  attorneys  and  auditors),  officers,
directors  or  employees  of such  Borrower,  provided  that each such Person is
required by such Borrower to keep such information confidential.

     SECTION  11.17.  ENTIRE  AGREEMENT,  ETC.  This  Agreement  (including  all
schedules and exhibits  referred to herein),  the Notes, the Fee Letters and all
other Loan Documents  constitute the entire contract  between the parties hereto
with respect to the subject  matter  hereof and thereof and shall  supersede and
take the place of any other  instrument  purporting  to be an  agreement  of the
parties hereto relating to such subject matter.

     SECTION   11.18.   NO  STRICT   CONSTRUCTION.   The  parties   hereto  have
participated,  jointly in the negotiation and drafting of this Agreement. In the
event of any  ambiguity  or question of intent or  interpretation  arises,  this
Agreement  shall be construed as if drafted jointly by the parties hereto and no
presumption or burden of proof shall arise favoring or disfavoring  any party by
virtue of authorship of any provisions of this  Agreement.  IN WITNESS  WHEREOF,


                                       94

the parties  hereto have caused this Agreement to be duly executed by their duly
