date of any Advance that it will not make available its Specified Percentage of
any Advance, Administrative Agent may assume that such Lender has made the
appropriate amount available in accordance with Section 2.02(a), and
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower a corresponding amount. If and to the extent any Lender shall not
have made such amount available to Administrative Agent, such Lender and the
Borrower agree to repay to Administrative Agent immediately on demand such
corresponding amount together with interest thereon, from the date such amount
is made available to the Borrower until the date such amount is repaid to
Administrative Agent, at (i) in the case of the Borrower, the Base Rate, and
(ii) in the case of such Lender, the Federal Funds Rate.

      (f) The failure by any Lender to make available its Specified Percentage
of any Advance hereunder shall not relieve any other Lender of its obligation,
if any, to make available its Specified Percentage of any Advance. In no event,
however, shall any Lender be responsible for the failure of any other Lender to
make available any portion of any Advance.

      (g) The Borrower shall indemnify each Lender against any Consequential
Loss incurred by each Lender as a result of (i) any failure by the Borrower to
fulfill, on or before the date specified for the Advance, the conditions to the
Advance set forth herein or (ii) the Borrower's requesting that an Advance not
be made on the date specified in the Borrowing Notice.

      SECTION 2.03. Evidence of Debt.

      (a) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower to such Lender
resulting from such Lender making its Specified Percentage of the Loan to the
Borrower, including the amounts of principal and interest payable and paid to
such Lender from time to time under this Agreement.

      (b) The entries made in the accounts maintained pursuant to paragraph (a)
above shall be prima facie evidence of the existence and amounts of the
obligations therein recorded; provided however, that the failure of any Lender
or the Administrative Agent to maintain such accounts or any error therein shall
not in any manner affect the obligations of the Borrower to repay the Loan in
accordance with its terms.

      (c) Notwithstanding anything in this Agreement or in any of the other Loan
Papers to the contrary, and in addition to the required payments set forth in
this Agreement, all outstanding

                                       24
<PAGE>   30

amounts under the Loan and all remaining outstanding portions of the Obligations
shall be due and payable on the Maturity Date.

      SECTION 2.04. Fees.

      (a) Commitment Fee. Subject to Section 10.09 hereof, the Borrower shall
pay to Administrative Agent for the Ratable account of Lenders, a commitment fee
on the average daily amount of the difference between the Commitment and the sum
of (i) all Advances outstanding, plus (ii) the face amount of all outstanding
Letters of Credit, at a per annum rate determined below, payable in arrears on
each Quarterly Date and on the Maturity Date, commencing with the first
Quarterly Date after the Closing Date, and continuing until the Maturity Date.

</TABLE>

      (b) Certain Fees. The Borrower agrees to pay to each Lender, through the
Administrative Agent, such other fees and administrative fees as are set forth
in any Fee Letters in accordance with such terms set forth in the Fee Letters.
All Fees shall be paid on the dates due, in immediately available funds, to the
Administrative Agent for distribution, if and as appropriate, among the Lenders.
Once paid, none of the Fees shall be refundable, except in accordance with the
provisions of Section 10.09 hereof.

      SECTION 2.05. Reduction of Commitment.

      (a) Voluntary Commitment Reduction. The Borrower shall have the right from
time to time upon notice by the Borrower to the Administrative Agent not later
than 1:00 p.m., three Business Days in advance, to reduce the Commitment, in
whole or in part; provided, however, that the Borrower shall pay the accrued
Commitment Fee on the amount of each such reduction, if any, and any partial
reduction shall be in an aggregate amount which is not less than $1,000,000 and
an integral multiple of $500,000. Such notice shall specify the amount of
reduction and the proposed date of such reduction. The Borrower may state that
such notice is conditioned upon the effectiveness of other credit facilities, in
which case, such notice may be revoked by the Borrower on or prior to the date
of its effectiveness if such condition is not satisfied; provided that Borrower
shall be responsible for any related Consequential Losses.

      (b) Mandatory Termination of the Commitment. The Commitment shall reduce
to zero and terminate on the Maturity Date.

                                       25
<PAGE>   31

      (c) Mandatory Reduction of the Commitment. The Commitment shall be
permanently reduced from time to time on the date of, and by the amount of, each
mandatory prepayment that would be required to be made in accordance with the
terms of Section 2.06(b) hereof regardless of whether there are actually any
outstanding Advances or undrawn Letters of Credit under this Agreement.

      (d) Commitment Reductions, Generally. To the extent the sum of the
aggregate outstanding Advances plus the undrawn face amount of outstanding
Letters of Credit exceed the Commitment after any reduction thereof, the
Borrower shall immediately repay on the date of such reduction, any such excess
amount and all accrued interest thereon, together with any amounts constituting
any Consequential Loss and/or cash collateralize any undrawn portion of any
outstanding Letters of Credit. Once reduced or terminated pursuant to this
Section 2.05, the Commitment may not be increased or reinstated.

      SECTION 2.06.     Prepayments.

      (a) Optional Prepayments. The Borrower may, upon at least three Business
Days prior written notice to Administrative Agent stating the proposed date and
aggregate principal amount of the prepayment, prepay the outstanding principal
amount of any Advances in whole or in part, together with accrued interest to
the date of such prepayment on the principal amount prepaid without premium or
penalty other than any Consequential Loss; provided, however, that in the case
of a prepayment of a Base Rate Advance, the notice of prepayment may be given by
telephone by 11:00 a.m. on the date of prepayment. Each partial prepayment
shall, in the case of Base Rate Advances, be in an aggregate principal amount of
not less than $500,000 or a larger integral multiple of $100,000 in excess
thereof and, in the case of LIBOR Advances, be in an aggregate principal amount
of not less than $1,000,000 or a larger integral multiple of $500,000 in excess
thereof. If any notice of prepayment is given, the principal amount stated
therein, together with accrued interest on the amount prepaid and the amount, if
any, due under Sections 2.11 and 2.14 hereof, shall be due and payable on the
date specified in such notice.

      (b) Mandatory Prepayments. The Borrower shall make an immediate and
mandatory prepayment of the Loan and/or cash collateralization of the Letters of
Credit by an amount in each case equal to: (i) 100% of the net cash proceeds
from the issuance of any equity or Capital Stock by the Parent or any of its
Subsidiaries (whether as a result of the exercise of a Stock Right or
otherwise), except (A) Capital Stock of the Parent issued (I) pursuant to the
Private Offering, (II) pursuant to the Conversion Rights Agreement, (III) in
accordance with any Stock Plan, and (IV) pursuant to any Stock Rights existing
on the Closing Date, or (B) Capital Stock of Telergy Canada issued to comply
with applicable Law of Canada, (ii) 100% of the Net Proceeds from Asset
Dispositions and Fiber Dispositions by the Parent, the Borrower or any of their
Subsidiaries (specifically excluding Fiber Dispositions not prohibited by the
terms of Section 7.15 hereof) (this section in and of itself not permitting any
such transactions, for permitted Asset Dispositions, see Section 7.06 hereof and
for prohibited Fiber Dispositions, see Section 7.15 hereof), provided that no
prepayment must be made for Asset Dispositions (A) in the ordinary course of
business, (B) among the Parent, the Borrower and their Wholly Owned Subsidiaries
or Telergy Central and (C) the Net Proceeds of which aggregate in an amount over
the term of this Agreement less than

                                       26
<PAGE>   32

$1,000,000; (iii)100% of the net proceeds received by the Parent, the Borrower
or their Subsidiaries in connection with the incurrence of Debt for Borrowed
Money of the Parent, the Borrower or any of their Subsidiaries after the date
hereof (this section in and of itself not permitting any such transactions, for
permitted debt incurrence see Section 7.02 hereof) except with respect to the
incurrence by the Borrower of Debt for Borrowed Money in accordance with the
terms of Section 7.02 hereof; and (iv) 100% of the Obligations if a Change in
Control occurs.

      (c) Outstanding Advances in Excess of the Available Commitment. On each
and every date that the sum of (i) the outstanding Advances plus (ii) the
undrawn portion of any outstanding Letters of Credit exceed the Available
Commitment, the Borrower shall make an immediate and mandatory prepayment of the
Loan and/or cash collateralize the undrawn portion of any outstanding Letters of
Credit by an amount in each case equal to the amount of outstanding Advances in
excess of the Available Commitment.

      (d) Prepayments, Generally. Any prepayment of Advances pursuant to this
Section 2.06 shall be applied first to Base Rate Advances, if any, then
outstanding under the Loan, second to LIBOR Advances for which the date of
prepayment is the last day of the applicable Interest Period, if any,
outstanding under the Loan and third to LIBOR Advances with the shortest
remaining Interest Periods outstanding under the Loan.

      SECTION 2.07. Mandatory Repayment. The Borrower agrees that all
Obligations are due and payable in full on the Maturity Date.

      SECTION 2.08. Interest. Subject to Section 2.09 below, the Borrower shall
pay interest on the unpaid principal amount of each Advance from the date of
such Advance until such principal shall be paid in full, at the following rates,
as selected by the Borrower in accordance with the provisions of Section 2.02
hereof:

            (a) Base Rate Advances. Base Rate Advances shall bear interest at a
      rate per annum equal to the Base Rate as in effect from time to time. If
      the amount of interest payable in respect of any interest computation
      period is reduced to the Highest Lawful Rate pursuant to the definition of
      "Base Rate" and the amount of interest payable in respect of any
      subsequent interest computation period would be less than the Maximum
      Amount, then the amount of interest payable in respect of such subsequent
      interest computation period shall be automatically increased to the
      Maximum Amount; provided that at no time shall the aggregate amount by
      which interest paid has been increased pursuant to this sentence exceed
      the aggregate amount by which interest has been reduced pursuant to the
      definition of "Base Rate".

            (b) LIBOR Advances. LIBOR Advances shall bear interest at the rate
      per annum equal to the LIBOR Rate applicable to such Advance. If the
      amount of interest payable in respect of any interest computation period
      is reduced to the Highest Lawful Rate pursuant to the definition of "LIBOR
      Rate" and the amount of interest payable in respect of any subsequent
      interest computation period would be less than the Maximum Amount, then
      the amount of interest payable in respect of such subsequent interest
      computation period shall

                                       27
<PAGE>   33

      be automatically increased to the Maximum Amount; provided that at no time
      shall the aggregate amount by which interest paid has been increased
      pursuant to this sentence exceed the aggregate amount by which interest
      has been reduced pursuant to the definition of "LIBOR Rate".

            (c) Payment Dates. Accrued and unpaid interest on Base Rate Advances
      shall be paid quarterly in arrears on each Quarterly Date and on the
      appropriate maturity, repayment or prepayment date. Accrued and unpaid
      interest on LIBOR Advances shall be paid on the last day of the
      appropriate Interest Period and on the date of any prepayment or repayment
      of such Advance; provided, however, that if any Interest Period for a
      LIBOR Advance exceeds three months, interest shall also be paid on each
      date occurring during the Interest Period which is the three month
      anniversary date of the first day of the Interest Period.

      SECTION 2.09. Default Interest. During the continuation of any Event of
Default, the Borrower shall pay, on demand, interest (after as well as before
judgment to the extent permitted by Law) on the principal amount of all Advances
outstanding and on all other Obligations due and unpaid hereunder equal to the
lesser of the (a) the Highest Lawful Rate and (b) the Base Rate (whether or not
in effect) plus 2.00% per annum.

      SECTION 2.10.     Continuation and Conversion Elections.

      (a) The Borrower may upon irrevocable written notice to Administrative
Agent and subject to the terms of this Agreement:

            (i) elect to convert, on any Business Day, all or any portion of
      outstanding Base Rate Advances (in an aggregate amount not less than
      $1,000,000 or a larger integral multiple of $500,000 in excess thereof)
      into LIBOR Advances.

            (ii) elect to convert at the end of any Interest Period therefor,
      all or any portion of outstanding LIBOR Advances comprised in the same
      Borrowing (in an aggregate amount not less than $500,000 or a larger
      integral multiple of $100,000 in excess thereof) into Base Rate Advances;
      or

            (iii) elect to continue, at the end of any Interest Period therefor,
      any LIBOR Advances;

provided, however, that if the aggregate amount of outstanding LIBOR Advances
comprised in the same Borrowing shall have been reduced as a result of any
payment, prepayment or conversion of part thereof to an amount less than
$1,000,000, the LIBOR Advances comprised in such Borrowing shall automatically
convert into Base Rate Advances at the end of each respective Interest Period.

      (b) The Borrower shall deliver a notice of conversion or continuation (a
"Notice of Conversion/Continuation"), in substantially the form of Exhibit G
hereto, to Administrative Agent not later than (i) 12:00 noon three Business
Days prior to the proposed date of conversion or continuation, if the Advances
or any portion thereof are to be converted into or continued as LIBOR

                                       28
<PAGE>   34

Advances; and (ii)10:00 a.m. on the proposed date of conversion or continuation,
if the Advances or any portion thereof are to be converted into Base Rate
Advances.

      Each such Notice of Conversion/Continuation shall be by telecopy or
telephone, promptly confirmed in writing, specifying therein:

            (i)   the proposed date of conversion or continuation;

           (ii)   the aggregate amount of Advances to be converted or continued;

          (iii)   the nature of the proposed conversion or continuation; and

           (iv)   the duration of the applicable Interest Period.

      (c) If, upon the expiration of any Interest Period applicable to LIBOR
Advances, the Borrower shall have failed to select a new Interest Period to be
applicable to such LIBOR Advances or if an Event of Default shall then have
occurred and be continuing, the Borrower shall be deemed to have elected to
convert such LIBOR Advances into Base Rate Advances effective as of the
expiration date of such current Interest Period.

      (d) Upon receipt of a Notice of Conversion/Continuation, Administrative
Agent shall promptly notify each Lender thereof. All conversions and
continuations shall be made pro rata among Lenders based on their Specified
Percentage of the respective outstanding principal amounts of the Advances with
respect to which such notice was given held by each Lender.

      (e) Notwithstanding any other provision contained in this Agreement, after
giving effect to any conversion or continuation of any Advances, there shall not
be outstanding Advances with more than five different Interest Periods in the
aggregate under the Loan.

      SECTION 2.11. Funding Losses. If the Borrower makes any payment or
prepayment of principal with respect to any LIBOR Advance (including payments
made after any acceleration thereof) or converts any Advance from a LIBOR
Advance on any day other than the last day of an Interest Period applicable
thereto, or if the Borrower fails to prepay, borrow, convert or continue any
LIBOR Advance after a notice of prepayment, borrowing, conversion or
continuation has been given (or is deemed to have been given) to Administrative
Agent, the Borrower shall pay to each Lender on demand (subject to Section 10.09
hereof) any Consequential Loss. The Borrower agrees that each Lender is not
obligated to actually reinvest the amount prepaid in any specific obligation as
a condition to receiving any Consequential Loss, or otherwise.

      SECTION 2.12. Computations and Manner of Payments.

      (a) The Borrower shall make each payment hereunder and under the other
Loan Papers not later than 1:00 p.m. on the day when due in same day funds to
Administrative Agent, for the Ratable account of Lenders unless otherwise
specifically provided herein, at

                             Administrative Agent

                                       29
<PAGE>   35

                             Bank of America Plaza
                                901 Main Street
                                  14th Floor
                             Dallas, Texas  75202

for further credit to the account of the Borrower. No later than the end of each
day when each payment hereunder is made, the Borrower shall notify
Administrative Agent, telephone (800) 880-5537, facsimile (214) 209-2515, or
such other Person as Administrative Agent may from time to time specify.

      (b) Unless Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due hereunder that the
Borrower will not make payment in full, Administrative Agent may assume that
such payment is so made on such date and may, in reliance upon such assumption,
make distributions to Lenders. If and to the extent the Borrower shall not have
made such payment in full, each Lender shall repay to Administrative Agent
forthwith on demand the applicable amount distributed, together with interest
thereon at the Federal Funds Rate, from the date of distribution until the date
of repayment. The Borrower hereby authorizes each Lender, if and to the extent
payment is not made when due hereunder, to charge the amount so due against any
account of the Borrower with such Lender.

      (c) Subject to Section 10.09 hereof, interest on LIBOR Advances shall be
calculated on the basis of actual days elapsed but computed as if each year
consisted of 360 days. Subject to Section 10.09 hereof, interest on Base Rate
Advances, the Commitment Fees and other amounts due under the Loan Papers shall
be calculated on the basis of actual days elapsed but computed as if each year
consisted of 365 or 366 days, as the case may be. Such computations shall be
made including the first day but excluding the last day occurring in the period
for which such interest, payment or Fees are payable. Each determination by
Administrative Agent or a Lender of an interest rate, fee or commission
hereunder shall be conclusive and binding for all purposes, absent manifest
error. All payments under the Loan Papers shall be made in United States dollars
and without setoff, counterclaim or other defense.

      (d) Notwithstanding anything herein or in any Loan Paper to the contrary,
any payment made by the Borrower in excess of outstanding Advances, shall be
applied to outstanding amounts (or to reduce the commitment) of any other
outstanding Obligations.

      (e) Reference to any particular index or reference rate for determining
any applicable interest rate under this Agreement is for purposes of calculating
the interest due and is not intended as and shall not be construed as requiring
any Lender to actually fund any Advance at any particular index or reference
rate.

      SECTION 2.13. Sharing of Payments. If any Lender shall obtain any payment
(whether voluntary, involuntary, through the exercise of any right of set-off,
or otherwise) on account of its portion of the Loan in excess of its pro rata
share of payments made by the Borrower in accordance with such Lender's
Specified Percentage, such Lender shall forthwith purchase participations in the
portion of the Loan made by the other Lenders as shall be necessary to share the

                                       30
<PAGE>   36

excess payment pro rata in accordance with each Lender's Specified Percentage
with each of them; provided, however, that if any of such excess payment is
thereafter recovered from the purchasing Lender, its purchase from each Lender
shall be rescinded and each Lender shall repay the purchase price to the extent
of such recovery together with a pro rata share of any interest or other amount
paid or payable by the purchasing Lender in respect of the total amount so
recovered. The Borrower agrees that any Lender so purchasing a participation
from another Lender pursuant to this Section 2.13 may, to the fullest extent
permitted by Law, exercise all its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Lender were the
direct creditor of the Borrower in the amount of such participation.

      SECTION 2.14.     Yield Protection.

      (a If any Lender determines that either (i) the adoption, after the date
hereof, of any Applicable Law, rule, regulation or guideline regarding capital
adequacy applicable to commercial banks or financial institutions generally or
any change therein, or any change, after the date hereof, in the interpretation
or administration thereof by any Tribunal, central bank or comparable agency
charged with the interpretation or administration thereof, or (ii) compliance by
any Lender (or Lending Office of any Lender) with any request or directive made
after the date hereof applicable to commercial banks or financial institutions
generally regarding capital adequacy (whether or not having the force of law) of
any such authority, central bank or comparable agency has the effect of reducing
the rate of return on such Lender's capital as a consequence of its obligations
hereunder to a level below that which such Lender could have achieved but for
such adoption, change or compliance (taking into consideration such Lender's
policies with respect to capital adequacy (but excluding consequences of such
Lender's negligence or intentional disregard of law or regulation)) by an amount
reasonably deemed by such Lender to be material, then from time to time, within
fifteen days after demand by such Lender, the Borrower shall pay to such Lender
such additional amount or amounts as will adequately compensate such Lender for
such reduction. Each Lender will notify the Borrower of any event occurring
after the date of this Agreement which will entitle such Lender to compensation
pursuant to this Section 2.14(a) as promptly as practicable after such Lender
obtains actual knowledge of such event; provided that no Lender shall be liable
for its failure or the failure of any other Lender to provide such notification.
A certificate of such Lender claiming compensation under this Section 2.14(a),
setting forth in reasonable detail the calculation of the additional amount or
amounts to be paid to it hereunder and certifying that such claim is consistent
with such Lender's treatment of similar customers having similar provisions
generally in their agreements with such Lender shall be conclusive in the
absence of manifest error. Each Lender shall use reasonable efforts to mitigate
the effect upon the Borrower of any such increased costs payable to such Lender
under this Section 2.14(a).

      (b If, after the date hereof, any Tribunal, central bank or other
comparable authority, at any time imposes, modifies or deems applicable any
reserve (including, without limitation, any imposed by the Board of Governors of
the Federal Reserve System), special deposit or similar requirement against
assets of, deposits with or for the amount of, or credit extended by, any
Lender, or imposes on any Lender any other condition affecting a LIBOR Advance,
the Notes or its obligation to make a LIBOR Advance; and the result of any of
the foregoing is to increase the cost to such Lender of making or maintaining
LIBOR Advances, or to reduce the amount of any sum

                                       31
<PAGE>   37

received or receivable by such Lender under this Agreement or under the Notes or
reimbursement obligations by an amount reasonably deemed by such Lender to be
material, then, within five days after demand by such Lender, the Borrower shall
pay to such Lender such additional amount or amounts as will compensate such
Lender for such increased cost or reduction. Each Lender will (i) notify the
Borrower and Administrative Agent of any event occurring after the date of this
Agreement that entitles such Lender to compensation pursuant to this Section
2.14(b), as promptly as practicable after such Lender obtains actual knowledge
of the event; provided that no Lender shall be liable for its failure or the
failure of any other Lender to provide such notification and (ii) use good faith
and reasonable efforts to designate a different Lending Office for LIBOR
Advances of such Lender if the designation will avoid the need for, or reduce
the amount of, the compensation and will not, in the sole opinion of such
Lender, be disadvantageous to such Lender. A certificate of such Lender claiming
compensation under this Section 2.14(b) setting forth in reasonable detail the
computation of the additional amount or amounts to be paid to it hereunder and
certifying that such claim is consistent with such Lender's treatment of similar
customers having similar provisions generally in their agreements with such
Lender shall be conclusive in the absence of manifest error. If such Lender
demands compensation under this Section 2.14(b), the Borrower may at any time,
on at least five Business Days' prior notice to such Lender, (i) repay in full
the then outstanding principal amount of LIBOR Advances of such Lender, together
with accrued interest thereon, or (ii) convert the LIBOR Advances to Base Rate
Advances in accordance with the provisions of this Agreement; provided, however,
that the Borrower shall be liable for the Consequential Loss arising pursuant to
those actions.

      (c Notwithstanding any other provision of this Agreement, if the
introduction of or any change in or in the interpretation or administration of
any Law shall make it unlawful, or any central bank or other Tribunal shall
assert that it is unlawful, for a Lender to perform its obligations hereunder to
make LIBOR Advances or to continue to fund or maintain LIBOR Advances hereunder,
then, on notice thereof and demand therefor by such Lender to the Borrower, (i)
each LIBOR Advance will automatically, upon such demand, convert into a Base
Rate Advance, and (ii) the obligation of such Lender to make or to convert
Advances into LIBOR Advances shall be suspended until such Lender notifies
Administrative Agent and the Borrower that such Lender has determined that the
circumstances causing such suspension no longer exist.

      (d Upon the occurrence and during the continuance of any Default or Event
of Default, (i) each LIBOR Advance will automatically, on the last day of the
then existing Interest Period therefor, convert into a Base Rate Advance and
(ii) the obligation of each Lender to make or to convert Advances into LIBOR
Advances shall be suspended.

      (e Failure on the part of any Lender to demand compensation for any
increased costs, increased capital or reduction in amounts received or
receivable or reduction in return on capital pursuant to this Section 2.14 with
respect to any period shall not constitute a waiver of any Lender's right to
demand compensation with respect to such period or any other period, subject,
however, to the limitations set forth in this Section 2.14.

                                       32
<PAGE>   38

      (f The term "Lender" for purposes of this Section shall include the
Administrative Agent and the Issuing Bank. The obligations of the Borrower under
this Section 2.14 shall survive any termination of this Agreement.

      (g Determinations by Lenders for purposes of this Section 2.14 shall be
conclusive, absent manifest error. Any certificate delivered to the Borrower by
a Lender pursuant to this Section 2.14 shall include in reasonable detail the
basis for such Lender's demand for additional compensation and a certification
that the claim for compensation is consistent with such Lender's treatment of
similar customers having similar provisions generally in their agreements with
such Lender.

      (h If Majority Lenders notifies Administrative Agent that the LIBOR Rate
for any Interest Period for any LIBOR Advances will not adequately reflect the
cost to such Lender of making, funding or maintaining LIBOR Advances for such
Interest Period, Administrative Agent shall promptly so notify the Borrower,
whereupon (i) each such LIBOR Advance will automatically, on the last day of the
then existing Interest Period therefor, convert into a Base Rate Advance and
(ii) the obligation of such Lender to make or to convert Advances into LIBOR
Advances shall be suspended until such Lender notifies Administrative Agent that
such Lender has determined that the circumstances causing such suspension no
longer exist and Administrative Agent notifies the Borrower of such fact.

      SECTION 2.15. Taxes.

      (a) Any and all payments by the Borrower hereunder shall be made, in
accordance with Section 2.12 hereof, free and clear of and without deduction for
any and all current or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding franchise
taxes, excise taxes and taxes based on net income (including branch profit
taxes).

      (b) In addition, the Borrower agrees to pay to the relevant Governmental
Authority in accordance with Applicable Law any current or future stamp or
documentary taxes or similar levies that arise from and payment made hereunder
or from the execution, delivery or registration of, or otherwise with respect
to, this Agreement ("Other Taxes").

      (c) The Borrower will indemnify the Administrative Agent, the Issuing
Bank, and each Lender for the full amount of taxes and Other Taxes paid by the
Administrative Agent, the Issuing Agent or such Lender and any liability
(including penalties, interest and expenses (including reasonable attorney's
fees and expenses)) arising therefrom or with respect thereto, whether or not
such taxes or Other Taxes were correctly or legally asserted by the relevant
Governmental Authority. A certificate as to the amount of such payment or
liability prepared by the Administrative Agent, a Lender, the Issuing Agent or
the Administrative Agent on its behalf, absent manifest error, shall be final,
conclusive and binding for all purposes. Such indemnification shall be made
within 30 days after the date the Administrative Agent or any affected Lender
makes written demand therefor.

      (d) Each Lender and the Administrative Agent hereby agrees to reasonably
pursue any available refund of, or credit for or similar tax benefit with
respect to any taxes or Other Taxes of

                                       33
<PAGE>   39

which it is aware, provided that, no such obligation on the part of the
Administrative Agent or any Lender shall require such Person to incur an
unreimbursed loss or unreimbursed cost or expense or otherwise take any action
inconsistent with its internal policies or legal or regulatory restrictions or
suffer any disadvantage or burden deemed by it to be significant. The
Administrative Agent and each such Lender will promptly remit to the Borrower an
amount equal to any refund, credit or benefit received by it.

      (e) Each Lender organized under the Laws of a jurisdiction outside the
United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Lender listed on the signature pages hereof and on
or prior to the date on which it becomes a Lender in the case of each other
Lender, and from time to time thereafter, including, without limitation, upon
the expiration or obsolescence of any previously delivered form or upon the
written request of Borrower or Administrative Agent (but only so long as such
Lender remains lawfully able to do so) shall provide Borrower and Administrative
Agent with (i) Internal Revenue Service Form 1001 or 4224, as appropriate, or
any successor form prescribed by the Internal Revenue Service, certifying that
such Lender is entitled to benefits under an income tax treaty to which the
United States is a party which reduces the rate of withholding tax on payments
of interest or certifying that the income receivable pursuant to this Agreement
is effectively connected with the conduct of a trade or business in the United
States, (ii) Internal Revenue Service Form W-8 or W-9, as appropriate, or any
successor form prescribed by the Internal Revenue Service, and (iii) any other
form or certificate required by any taxing authority (including any certificate
required by Sections 871(h) and 881(c) of the Internal Revenue Code), certifying
that such Lender is entitled to an exemption from or a reduced rate of tax on
payments pursuant to this Agreement or any of the other Loan Papers.

      (f) For any period with respect to which a Lender has failed to provide
Borrower and Administrative Agent with the appropriate form pursuant to Section
2.15(e) hereof (unless 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 indemnifications under this Section 2.15
hereof with respect to Taxes imposed by the United States; provided, however,
that should a Lender, which is otherwise exempt from or subject to a reduced
rate of withholding tax, become subject to Taxes because of its failure to
deliver a form required hereunder, Borrower shall take such steps as such Lender
shall reasonably request to assist such Lender to recover such Taxes.

      SECTION 2.16. Collateral and Collateral Call.

      (a) Collateral. Payment of the Obligations will be secured by:

            (i) a first perfected security interest in 100% of the Pledged
      Stock,

            (ii) guaranties of the Obligations by each Guarantor,

            (iii) a first perfected security interest (except for Permitted
      Liens and Liens permitted pursuant to the terms of Section 7.03 hereof) in
      all accounts, inventory, non-fixture equipment and fiber (other than
      permitted Fiber Dispositions allowed pursuant to Section

                                       34
<PAGE>   40

      7.15 hereof, and only to the extent such Fiber Disposition has actually
      occurred) of the Parent and the Borrower, except the Excluded Assets,

            (iv) upon the execution of the Note, a first perfected security
      interest (except for Permitted Liens and Liens permitted pursuant to the
      terms of Section 7.03 hereof) in all accounts, inventory, non-fixture
      equipment of the Parent's and the Borrower's Subsidiaries except Telergy
      Canada, except the Excluded Assets, and

            (v) a first perfected security interest (except for Permitted Liens
      and Liens permitted pursuant to the terms of Section 7.03 hereof) in all
      assets and properties, both real and personal, of Telergy Parkway,

(collectively, together with all other properties or assets of the Parent, the
Borrower and their Subsidiaries and other Persons that secure the Obligations
from time to time, but specifically excluding the Excluded Stock and the
Excluded Assets, the "Collateral"). The Borrower agrees that it will, and will
cause the Parent and their Subsidiaries to execute and deliver, or cause to be
executed and delivered, such documents as the Administrative Agent may from time
to time reasonably request to create and perfect a first Lien (subject to
Permitted Liens and Liens permitted pursuant to the terms of Section 7.03
hereof) for the benefit of the Administrative Agent and the Lenders in the
Collateral in accordance with the terms of this Section 2.16(a).

      (b) Collateral Call. The Borrower agrees after the date hereof upon the
creation, formation or acquisition of any direct or indirect Subsidiary of the
Parent, to immediately pledge or cause to be pledged 100% of the Capital Stock
of any such Subsidiary that is owned by the Parent, the Borrower or any of their
Subsidiaries to secure the Obligations, pursuant to a pledge agreement
substantially similar to those executed in connection herewith, and to promptly
deliver to the Administrative Agent all certificates or other documentation
evidencing 100% of such Capital Stock and, if such Capital Stock is stock of a
corporation, together with stock powers executed in blank. The Borrower agrees,
notwithstanding (a) above, promptly upon request by the Administrative Agent, to
use its commercially reasonable efforts to take all actions necessary or
advisable to promptly grant the Administrative Agent on behalf of the Lenders a
Lien and/or security interest in all or any portion of the tangible and
intangible assets and properties of the Parent, the Borrower and their
Subsidiaries except Telergy Canada, owned by the Parent or the Borrower directly
or indirectly (whether through Capital Stock or otherwise), including to
immediately pledge/mortgage or grant a first priority security interest in real
property to secure the Obligations, provided that under no circumstances shall
the Parent or the Borrower be required to grant a Lien and/or security interest
in the Excluded Stock, Excluded Assets, any other assets of the Parent, the
Borrower or any of their Subsidiaries subject to a Permitted Lien or a Lien
permitted by Section 7.03 hereof, or in any other assets (or assign any other
assets) with respect to which the Parent, the Borrower or their Subsidiaries are
contractually prohibited or prohibited by Law from assignment or granting a
Lien.

      (c) To the extent that any new Subsidiaries have been created since the
Closing Date, (i) if such Subsidiaries are non-PUC regulated Subsidiaries, 100%
of the Capital Stock of the Subsidiaries will be pledged to secure the
Obligations, the Subsidiaries will execute a guaranty of the Obligations and the
Subsidiaries will execute a security agreement pledging all their assets, other

                                       35
<PAGE>   41

than Excluded Assets, to secure the Obligations and (ii) if such Subsidiaries
are PUC regulated Subsidiaries, 100% of the Capital Stock of the Subsidiaries
will be pledged to secure the Obligations, the Subsidiaries will become
co-makers of the Notes and the Subsidiaries will execute a security agreement
pledging all their assets, other than Excluded Assets, to secure the
Obligations.

      SECTION 2.17. Conditions Precedent to the Increase of the Commitment.

      Prior to March 31, 2000, upon written request by the Borrower to
Administrative Agent and the other existing Lenders of its election ten Business
Days prior to the proposed effective date of the proposed increase, the
Commitment shall, subject to the further terms and conditions set forth below,
increase to a maximum of $200,000,000 in the manner set forth below:

            (a) On any date of proposed increase, the representations and
      warranties contained in Article V hereof are true and correct on such
      date, as though made on and as of such date, except to the extent
      expressly made only as of a prior date; and

            (b) On any date of proposed increase, no Default or Event of Default
      shall exist on any such date, and no Default or Event of Default would

      the Borrower up to the amount of the Commitment; and

            (c) On any date of proposed increase, no event shall have occurred
      that could reasonably be expected to have a Material Adverse Effect since
      December 31, 1998; and

            (d) On any date of proposed increase, the sum of (i) all Advances
      outstanding (after giving effect to any proposed Advance to be made on
      such date), plus (ii) the aggregate face amount of all outstanding Letters
      of Credit (after giving effect to any proposed Letter of Credit to be made
      on such date), plus (iii) (without duplication) the sum of all
      reimbursement obligations with respect to all outstanding Letters of
      Credit, shall not exceed the Commitment; and

            (e) The proposed increase shall occur prior to March 31, 2000 and
      the Commitment as increased shall not be in excess of the sum of the
      Commitment prior to such increase plus the Unavailable Commitment prior to
      such increase; and

            (f) Upon satisfaction of each of the conditions precedent in this
      Section 2.17, the Borrower shall be entitled to increase the Commitment
      not more than one time, in an aggregate amount for such increase not to
      exceed the Unavailable Commitment. Each Lender specified by the Borrower
      shall have received not less than ten days' prior written notice from the
      Borrower requesting such Commitment increase. Each such Lender electing to
      participate in such Commitment increase shall commit to an amount not less
      than $5,000,000, but shall accept any allocation amount designated by the
      Borrower and the Administrative Agent that is equal to or less than its
      proposed portion of the Commitment increase; and

                                       36
<PAGE>   42

            (g) Notwithstanding anything herein or in any other Loan Paper to
      the contrary, (i) the Borrower is not obligated to allocate to any
      existing Lender any portion of, the proposed increase, and the Borrower
      and the Administrative Agent may agree to add other creditors in
      connection with any such proposed increase. Each existing Lender agrees
      and acknowledges that new creditors may be allocated all or any portion of
      the proposed increase upon the determination of the Borrower and the
      Administrative Agent; and

            (h) Each of the new Lenders electing to participate in the proposed
      increase shall commit to a minimum amount of $10,000,000 and $5,000,000
      multiples thereof, although such new Lender shall accept any allocation
      equal to or less than its proposed portion of the Commitment increase; and

            (i) The Administrative Agent shall have received a certificate from
      the Borrower to the effect that (i) such increase has received all
      required regulatory approvals, if necessary, and is in compliance with all
      Applicable Laws, and (ii) no other approvals or consents from any Person
      are required by any such Person except to the extent they have been
      received; and

            (j) Each new Lender (including any new Lenders party hereto) shall
      have received a promissory Note, and the Borrower and each new Lender
      agrees to execute any and all such documents deemed necessary by the
      Administrative Agent in order to effectuate this Section 2.17 (whether
      UCC-1s, new documentation relating to any Collateral, Guaranty or
      otherwise); and

            (k) On the date of increase, the Administrative Agent shall deliver
      to each Lender evidence of new Specified Percentages adjusted to give
      effect to the increase in the Commitment; and

            (l) On or prior to the date of increase, each new Lender being added
      to the credit facility shall deliver to the Borrower and the
      Administrative Agent documentation acceptable to the Administrative Agent
      evidencing such new Lender's acceptance of this Agreement and all the
      other Loan Papers in form and substance reasonably acceptable to the
      Administrative Agent (and making such lender a party to this Agreement and
      the other Loan Papers); and

            (m) The Administrative Agent shall have received financial
      projections in form and substance reasonably acceptable to the Lenders and
      demonstrating compliance with the financial covenants set forth in Section
      7.01 hereof throughout the term of this Agreement; and

            (n) The Commitment shall (i) never exceed the sum of the Commitment
      (as in effect prior to giving effect to the increase specified in this
      Section 2.17) plus the Unavailable Commitment, as each is reduced in
      accordance with Section 2.05 hereof, this Section 2.17 and the other terms
      of this Agreement, and (ii) never increase except to the extent, and not
      to exceed such amount, that the Unavailable Commitment is in excess of
      zero; and

                                       37
<PAGE>   43

            (o) The Unavailable Commitment shall be reduced in accordance with
      this Section 2.17 dollar for dollar for each increase in the Commitment;
      and

            (p) The Administrative Agent on behalf of each Lender shall have
      received all amendments to security agreements, deeds of trust and
      mortgages as the Administrative Agent shall deem necessary to maintain its
      valid and perfected Lien; and

      No Lender shall be obligated to increase the dollar amount of its share of
the Commitment without its written consent in its sole discretion. In connection
with any increase to the Commitment in accordance with the terms of this Section
2.17, each existing Lender (regardless of whether such Lender is participating
in such increase) agrees to execute any and all agreements requested by the
Administrative Agent to effectuate the intent of this Section 2.17.
Notwithstanding anything contained herein to the contrary, the limitations
placed upon assignments set forth in Section 10.04 hereof shall not apply to
proposed increases pursuant to this Section.

                                  ARTICLE III

                              Letters of  Credit

      SECTION 3.01. Issuance of Letters of Credit. The Borrower shall give the
Administrative Agent not less than five Business Days prior written notice of a
request for the issuance of a Letter of Credit, and the Administrative Agent
shall promptly notify each Lender of such request. Upon receipt of the
Borrower's properly completed and duly executed Applications, and subject to the
terms of such Applications and to the terms of this Agreement, the
Administrative Agent agrees to issue Letters of Credit on behalf of the Borrower
in an aggregate face amount not in excess of the lesser of (a) Letter of Credit
Commitment and (b) the remainder of the Available Commitment minus the sum of
all outstanding Advances plus the aggregate face amount of all outstanding
Letters of Credit. No Letter of Credit shall have a maturity extending beyond
the earliest of (i) the Maturity Date, or (ii) one year from the date of its
issuance, or (iii) such earlier date as may be required to enable the Borrower
to satisfy its repayment obligations under Section 2.07 hereof. Subject to such
maturity limitations and so long as no Default or Event of Default has occurred
and is continuing or would result from the renewal of a Letter of Credit, the
Letters of Credit may be renewed by the Administrative Agent and Issuing Bank in
their discretion. The Lenders shall participate Ratably in any liability under
the Letters of Credit and in any unpaid reimbursement obligations of the
Borrower with respect to any Letter of Credit in their Specified Percentages.
The undrawn amount of the Letters of Credit issued and outstanding and the
unpaid reimbursement obligations of the Borrower for such Letters of Credit
shall reduce the amount of the Available Commitment available, so that at no
time shall the sum of (i) all outstanding Advances in the aggregate, plus (ii)
the aggregate undrawn face amount of all outstanding Letters of Credit, plus
(iii) (without duplication) all outstanding reimbursement obligations related to
Letters of Credit, exceed the Available Commitment, and at no time shall the sum
of all Advances by any Lender made plus its Ratable share of amounts available
to be drawn under the Letters of Credit and the unpaid reimbursement obligations
of the Borrower in respect of such Letters of Credit exceed its Specified
Percentage of the Available Commitment.

                                       38
<PAGE>   44

      SECTION 3.02. Letters of Credit Fee. In consideration for the issuance of
each Letter of Credit, the Borrower shall pay to (a) the Administrative Agent
for its account and for the account of the Issuing Bank, application and
processing fees in the amount of the higher of (i) $350.00 and (ii) the product
of .125% multiplied by the face amount of such Letter of Credit on each Letter
of Credit, due and payable on the date of issuance of each Letter of Credit, and
(b) the Administrative Agent for the account of the Lenders in accordance with
their Specified Percentages or the Issuing Bank, as case may be, a per annum fee
for each Letter of Credit equal to the higher of (i) $350.00 and (ii) the
product of the Applicable Margin for a LIBOR Advance in effect on the date of
calculation multiplied by the face amount of each such Letter of Credit. Each
fee for each Letter of Credit under subsection (b) above shall be due and
payable to the Administrative Agent or the Issuing Bank, as the case may be,
quarterly as it accrues, on each Quarterly Date during the term of the Letter of
Credit and on the expiration or renewal of each such Letter of Credit, beginning
with the first such Quarterly Date after the issuance of each Letter of Credit
and ending on the expiration date of each such Letter of Credit.

      SECTION 3.03. Reimbursement Obligations.

      (a) The Borrower hereby agrees to reimburse Administrative Agent and the
Issuing Bank immediately upon demand by Administrative Agent, and in immediately
available funds, for any payment or disbursement made by Administrative Agent or
the Issuing Bank under any Letter of Credit. Payment shall be made by the
Borrower with interest on the amount so paid or disbursed by Administrative
Agent or the Issuing Bank from and including the date payment is made under any
Letter of Credit to and including the date of payment, at the lesser of (i) the
Highest Lawful Rate, and (ii) the sum of the Base Rate in effect from time to
time plus 2% per annum; provided, however, that if the Borrower would be
permitted under the terms of Section 2.01, Section 2.02 and Section 5.02 to
borrow Advances in amounts at least equal to their reimbursement obligation for
a drawing under any Letter of Credit, a Base Advance by each Lender in an amount
equal to such Lender's Specified Percentage shall automatically be deemed made
on the date of any such payment or disbursement made by Administrative Agent or
the Issuing Bank in the amount of such obligation and subject to the terms of
this Agreement.

      (b) The Borrower hereby also agrees to pay to Administrative Agent
immediately upon demand by Administrative Agent or the Issuing Bank and in
immediately available funds, as security for its reimbursement obligations in
respect of the Letters of Credit under Section 3.03(a) hereof and any other
amounts payable hereunder and under the Notes, an amount equal to the aggregate
amount available to be drawn under Letters of Credit then outstanding,
irrespective of whether the Letters of Credit have been drawn upon, upon an
Event of Default. Any such payments shall be deposited in a separate account
designated "Telergy Special Account" or such other designation as Administrative
Agent shall elect. All such amounts deposited with Administrative Agent shall be
and shall remain funds of the Borrower on deposit with Administrative Agent and
may be invested by Administrative Agent as Administrative Agent shall determine.
Such amounts may not be used by Administrative Agent or the Issuing Bank to pay
the drawings under the Letters of Credit; however, such amounts may be used by
Administrative Agent and the Issuing Bank as reimbursement for Letter of Credit
drawings which Administrative Agent or the Issuing Bank has

                                       39
<PAGE>   45

paid. During the existence of an Event of Default but after the expiration of
any Letter of Credit that was not drawn upon, the Borrower may direct
Administrative Agent or the Issuing Bank to use any cash collateral for any such
expired Letter of Credit, if any, to reduce the amount of the Obligations. Any
amounts remaining in the Telergy Special Account after the date of the
expiration of all Letters of Credit and after all Obligations have been paid in
full, shall be repaid to the Borrower promptly after such expiration and such
payment in full.

      (c) The obligations of the Borrower under this Section 3.03 will continue
until all Letters of Credit have expired and all reimbursement obligations with
respect thereto have been paid in full by the Borrower and until all other
Obligations shall have been paid in full and Borrower's reimbursement
obligations hereunder are absolute and unconditional in all circumstances.

      (d) The Borrower shall be obligated to reimburse Administrative Agent and
the Issuing Bank upon demand for all amounts paid under the Letters of Credit as
set forth in Section 3.03(a) hereof; provided, however, if the Borrower for any
reason fails to reimburse Administrative Agent or the Issuing Bank in full upon
demand, whether by failing to or not being permitted to borrow Advances to pay
such reimbursement obligations or otherwise, the Lenders shall reimburse
Administrative Agent and the Issuing Bank in accordance with each Lender's
Specified Percentage for amounts due and unpaid from the Borrower as set forth
in Section 3.04 hereof; provided, however, that no such reimbursement made by
the Lenders shall discharge the Borrower's obligations to reimburse
Administrative Agent or the Issuing Bank.

      (e) The Borrower and the Parent shall indemnify and hold Administrative
Agent, the Issuing Bank, or any Lender, its officers, directors, representatives
and employees harmless from loss for any claim, demand or liability which may be
asserted against Administrative Agent, the Issuing Bank, or such indemnified
party in connection with actions taken under the Letters of Credit or in
connection therewith (including losses resulting from the negligence of
Administrative Agent or such indemnified party), and shall pay Administrative
Agent and the Issuing Bank for reasonable fees of attorneys (who may be
employees of Administrative Agent and the Issuing Bank) and legal costs paid or
incurred by Administrative Agent and the Issuing Bank in connection with any
matter related to the Letters of Credit, except for losses and liabilities
incurred as a direct result of the gross negligence or wilful misconduct of
Administrative Agent, the Issuing Bank, or such indemnified party. If the
Borrower for any reason fails to indemnify or pay Administrative Agent, the
Issuing Bank or such indemnified party of Administrative Agent as set forth
herein in full, the Lenders shall indemnify and pay Administrative Agent upon
demand, in accordance with each Lender's Specified Percentage of such amounts
due and unpaid from the Borrower. The provisions of this Section 3.03(e) shall
survive the termination of this Agreement.

      SECTION 3.04. Lenders' Obligations. Each Lender agrees, unconditionally
and irrevocably, to reimburse Administrative Agent or the Issuing Bank on demand
for such Lender's Specified Percentage of each draw paid by Administrative Agent
or the Issuing Bank under any Letter of Credit that is not reimbursed by the
Borrower. All amounts payable by any Lender under this subsection shall include
interest thereon at the Federal Funds Rate, from the date of the applicable draw
to the date of reimbursement by such Lender. No Lender shall be liable for the
performance or nonperformance of the obligations of any other Lender under this
Section. The

                                       40
<PAGE>   46

obligations of the Lenders under this Section shall continue after the Maturity
Date and shall survive termination of any Loan Papers.

      SECTION 3.05. Administrative Agent's Obligations.

      (a) Administrative Agent and the Issuing Bank each makes no representation
or warranty, and assumes no responsibility with respect to the validity,
legality, sufficiency or enforceability of any Application or any document
relative thereto or to the collectibility thereunder. Administrative Agent and
the Issuing Bank each assumes no responsibility for the financial condition of
the Parent, the Borrower and their Subsidiaries or for the performance of any
obligation of the Borrower. Administrative Agent and the Issuing Bank each may
use its discretion with respect to exercising or refraining from exercising any
rights, or taking or refraining from taking any action which may be vested in it
or which it may be entitled to take or assert with respect to any Letter of
Credit or any Application.

      (b) Administrative Agent and Issuing Bank each shall be under no liability
to any Lender with respect to anything Administrative Agent or Issuing Bank may
do or refrain from doing in the exercise of its judgment, the sole liability and
responsibility of Administrative Agent or Issuing Bank being to handle each
Lender's share on as favorable a basis as Administrative Agent or Issuing Bank
handles its own share and to promptly remit to each Lender its share of any sums
received by Administrative Agent under Article III or any Application.
Administrative Agent and Issuing Bank shall have no duties or responsibilities
except those expressly set forth herein, and those duties and liabilities shall
be subject to the limitations and qualifications set forth herein.

      (c) Neither Administrative Agent, Issuing Bank, nor any of its directors,
officers, or employees shall be liable for any action taken or omitted (whether
or not such action taken or omitted is expressly set forth herein) under or in
connection herewith or any other instrument or document in connection herewith,
except for gross negligence or willful misconduct, and no Lender waives its
right to institute legal action against Administrative Agent or Issuing Bank for
wrongful payment of any Letter of Credit due to Administrative Agent's or
Issuing Bank's gross negligence or willful misconduct. Administrative Agent and
Issuing Bank shall incur no liability to any Lender, the Borrower or any
Affiliate of the Borrower or Lender in acting upon any notice, document, order,
consent, certificate, warrant or other instrument reasonably believed by
Administrative Agent and Issuing Bank to be genuine or authentic and to be
signed by the proper party.

      SECTION 3.06 Reinstatement. The provisions of this Article III shall
continue to be effective, or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any of the reimbursement obligations in respect
of Letters of Credit is rescinded or must otherwise be restored or returned by
the Administrative Agent or the Issuing Bank upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of the Borrower or any other Obligor,
or upon or as a result of the appointment of a receiver, intervenor or
conservator of, or custodian, trustee or similar officer for, the Borrower or
any other Obligor or any part of its property, or otherwise, all as though such
payments had not been made.

any agent acting on their behalf, has taken any action which might cause this

or to violate the Exchange Act, in each case as in effect now or as the same may
hereafter be in effect from time to time.

      SECTION 4.12. Investment Company Act; Public Utility Holding Company Act.

faith by appropriate proceedings and for which the Parent, the Borrower or such
Subsidiary, as applicable, shall have set aside on its books adequate reserves.

      SECTION 4.15. No Material Misstatements. No written information, report,
financial statement, exhibit or schedule prepared by the Parent or the Borrower

contingent or otherwise, of the Parent, the Borrower and their Subsidiaries on a
consolidated basis; (ii) the present fair saleable value of the property of the
Parent, the Borrower and their Subsidiaries on a consolidated basis will be
greater than the amount that will be required to pay

                                       45
<PAGE>   51

the probable liability of the Parent, the Borrower and their Subsidiaries on a
consolidated basis on their debts and other liabilities, direct, subordinated,
contingent or otherwise, as such debts and other liabilities become absolute and
matured; (iii) the Parent, the Borrower and their Subsidiaries on a consolidated
basis will be able to pay their debts and liabilities, direct, subordinated,
contingent or otherwise, as such debts and liabilities become absolute and
matured; and (iv) the Parent, the Borrower and their Subsidiaries on a
consolidated basis will not have unreasonably small capital with which to
conduct the businesses in which they are engaged as such businesses are now
conducted and are proposed to be conducted following the Closing Date.

      (b) The Parent and the Borrower do not intend to, and do not believe that
they or any of their Subsidiaries on a consolidated basis will, incur debts
beyond their ability to pay such debts as they mature, taking into account the
timing and amounts of cash to be received by the Parent, the Borrower or any
such Subsidiary and the timing and amounts of cash to be payable on or in
respect of its Debt for Borrowed Money or the Debt for Borrowed Money of the
Parent, the Borrower or any such Subsidiary.

and correct description of all liability insurance and all other insurance
maintained by or for the Parent, Borrower or for or by their Subsidiaries as of

effect and all premiums have been duly paid. To the Parent's and the Borrower's
knowledge, the Parent, Borrower and their Subsidiaries have insurance in such
amounts and covering such risks and liabilities as are in accordance with normal

Subsidiaries names the Administrative Agent on behalf of the Lenders as loss
payee and will continue in that form until the Obligations have been paid in
full.

      (a) The properties owned, operated or leased by the Parent, the Borrower
and their Subsidiaries to the knowledge of the Borrower do not contain any
Hazardous Materials in amounts or concentrations which (i) constitute, or
constituted a violation of, or (ii) could reasonably be expected to give rise to
liability under, Environmental Laws, which violations and liabilities, in the
aggregate, could reasonably be expected to result in a Material Adverse Effect;

      (b) All Environmental Permits have been obtained and are in effect with
respect to the Properties and operations of the Parent, the Borrower and their
Subsidiaries, and the Properties and all operations of the Parent, the Borrower
and their Subsidiaries, to the knowledge of the Borrower, are in compliance, and
in the last two years, to the knowledge of the Borrower, have been in
compliance, with all Environmental Laws and all necessary Environmental Permits,
except to the extent that such non-compliance or failure to obtain any necessary
permits, in the aggregate, could not reasonably be expected to result in a
Material Adverse Effect;

      (c) Neither the Parent, the Borrower nor any of their Subsidiaries has
received any notice of an Environmental Claim in connection with the Properties
or the operations of the Parent, the Borrower or their Subsidiaries or with
regard to any Person whose liabilities for environmental

                                       46
<PAGE>   52

matters the Parent, the Borrower or their Subsidiaries has retained or assumed,

being threatened;

transported from the Properties, nor have Hazardous Materials been generated,
treated, stored or disposed of at, on or under any of the Properties in a manner

Environmental Law or which could reasonably be expected to result in a Material
Adverse Effect, nor have the Parent, the Borrower or their Subsidiaries retained
or assumed any liability contractually, with respect to the generation,
treatment, storage or disposal of Hazardous Materials, which transportation,
generation, treatment, storage or disposal, or retained or assumed liabilities,
in the aggregate, could reasonably be expected to result in a Material Adverse
Effect; and

      (e) The representations and warranties set forth in this Section 4.19 are
the sole and exclusive representations and warranties being made by the Parent
and the Borrower with respect to environmental matters.

      SECTION 4.20. Year 2000 Compliance. The Parent and the Borrower have (i)
undertaken a detailed review and assessment of all areas within its business and
operations that could reasonably be expected to be adversely affected by the
"Year 2000 Problem" (that is, the risk that computer applications used by the
Parent and the Borrower may be unable to recognize and perform properly the
date-sensitive functions before, during and after January 1, 2000), (ii)
developed a detailed plan and timeline for addressing the Year 2000 Problem on a
timely basis, and (iii) to date, implemented that plan in accordance with that
timetable. The Parent and the Borrower reasonably anticipate that all of their
computer applications which are material to their business and operations will
be able to properly perform date-sensitive functions before, during and after
January 1, 2000 (that is, be "Year 2000 Compliant").

obtained by the Parent, the Borrower or any of their Subsidiaries shall expire
without renewal or be suspended or revoked, or (ii) the Parent, the Borrower or

any such license;

      (p) any civil action, suit or proceeding shall be commenced against the
Parent, the Borrower or any of their Subsidiaries under any federal or state
racketeering statute (including, without limitation, the Racketeer Influenced
and Corrupt Organization Act of 1970)("RICO") and such suit shall be adversely
determined by a court of applicable jurisdiction, and which is either
non-appealable or which the Parent, the Borrower or such Subsidiary has elected
not to appeal and such adverse determination could reasonable be expected to
have a Material Adverse Effect; or any criminal action or proceeding shall be

any federal or state racketeering statute (including, without limitation, RICO);

      (q)   there shall occur a Change in Control;

in either case, could reasonably expected to have a Material Adverse Effect;

                                       67
<PAGE>   73

      (s) the Parent, the Borrower or any of their Subsidiaries shall fail to
comply in any respect with the Communications Act, or any rule or regulation
promulgated by the FCC or any applicable PUC, and such failure could reasonably
be expected to have a Material Adverse Effect; or any license or authorization
constituting authorizations, permits or licenses of the Parent, the Borrower or
any of their Subsidiaries material to the operation of the business of the
Parent, the Borrower and any of their Subsidiaries, has expired or shall expire
without having been renewed or shall be canceled or impaired, and such
expiration, cancellation or impairment could reasonably be expected to have a
Material Adverse Effect;

      (t) the Parent, the Borrower or any of their Subsidiaries shall fail to
operate its business for any period of time which, in the aggregate, could
reasonably be expected to have a Material Adverse Effect; or

      (u) any Substantial Portion shall not, for any reason (including, without
limitation, loss of FCC license, fiber network or otherwise) be operating for a
period in excess of 30 days. For purposes of this subsection (u), "Substantial
Portion" means any portion of the telecommunications system of the Parent, the
Borrower and their Subsidiaries that has generated, for the most recently
completed twelve month period, in excess of five percent of EBITDA.

      SECTION 8.02. Remedies Upon Default. If an Event of Default described in
Section 8.01(g) or Section 8.01(h) hereof shall occur with respect to the
Parent, the Borrower or any of their Subsidiaries, the Commitment shall be
immediately terminated and the aggregate unpaid principal balance of and accrued
interest on all Advances shall, to the extent permitted by applicable Law,
thereupon become due and payable concurrently therewith, without any action by
Administrative Agent or any Lender, and without diligence, presentment, demand,
protest, notice of protest or intent to accelerate, or notice of any other kind,
all of which are hereby expressly waived. Subject to the immediately foregoing
sentence, if any Event of Default shall occur and be continuing, then no LIBOR
Advances shall be available to the Borrower, and Administrative Agent may at its
election, and shall at the direction of Majority Lenders, do any one or more of
the following:

      (a) Declare the entire unpaid balance of all Advances immediately due and
payable, whereupon it shall be due and payable without diligence, presentment,
demand, protest, notice of protest or intent to accelerate or notice of any
other kind (except notices specifically provided for under Section 8.01), all of
which are hereby expressly waived (except to the extent waiver of the foregoing
is not permitted by applicable Law);

      (b) Terminate the Commitment;

      (c) Reduce any claim of Administrative Agent and Lenders to judgment;

      (d) Exercise any Rights afforded under any Loan Papers or by Law,
including, without limitation to the UCC, in equity or otherwise; or

      (e) Cause the Parent, the Borrower or any of their Subsidiaries to cash
collateralize the Letters of Credit.

<PAGE>   74

      SECTION 8.03. Cumulative Rights. All Rights available to Administrative
Agent and Lenders under the Loan Papers shall be cumulative of and in addition
to all other Rights granted thereto at Law or in equity, whether or not amounts
owing thereunder shall be due and payable and whether or not Administrative
Agent or any Lender shall have instituted any suit for collection or other
action in connection with the Loan Papers.

      SECTION 8.04. Waivers. The acceptance by Administrative Agent or any
Lender at any time and from time to time of partial payment of any amount owing
under any Loan Papers shall not be deemed to be a waiver of any Default or Event
of Default then existing. No waiver by Administrative Agent or any Lender of any
Default or Event of Default shall be deemed to be a waiver of any Default or
Event of Default other than such Default or Event of Default. No delay or
omission by Administrative Agent or any Lender in exercising any Right under the
Loan Papers shall impair such Right or be construed as a waiver thereof or an
acquiescence therein, nor shall any single or partial exercise of any such Right
preclude other or further exercise thereof or the exercise of any other Right
under the Loan Papers or otherwise.

      SECTION 8.05. Performance by Administrative Agent or any Lender. Should
any covenant of any of the Borrower, the Parent or their Subsidiaries fail to be
performed in accordance with the terms of the Loan Papers, Administrative Agent
may, at its option, perform or attempt to perform such covenant on behalf of
such Person. Notwithstanding the foregoing, it is expressly understood that
neither Administrative Agent nor any Lender assumes, and neither shall ever
have, except by express written consent of Administrative Agent or such Lender,
any liability or responsibility for the performance of any duties or covenants
of the Borrower, the Parent or their Subsidiaries.

      SECTION 8.06. Expenditures. The Borrower shall reimburse Administrative
Agent and each Lender for any sums spent by it in connection with the exercise
of any Right provided herein. Such sums shall bear interest at the lesser of (a)
the Base Rate in effect from time to time, plus 2.0%, and (b) the Highest Lawful
Rate, from the date spent until the date of repayment by the Borrower; provided,
that interest shall cease accruing on such expenditures commencing five days
after such expenditure unless and until Administrative Agent provides Borrower
with notice of such expenditure, at which time interest shall recommence accrual
as provided in this Section 8.06.

      SECTION 8.07. Control. None of the covenants or other provisions contained
in this Agreement shall, or shall be deemed to, give Administrative Agent or any
Lender any Rights to exercise control over the affairs and/or management of any
of the Borrower, the Parent or their Subsidiaries, the power of Administrative
Agent and each Lender being limited to the Rights to exercise the remedies
provided in this Article; provided, however, that if Administrative Agent or any
Lender becomes the owner of any partnership, stock or other equity interest in
any Person, whether through foreclosure or otherwise, it shall be entitled to
exercise such legal Rights as it may have by being an owner of such stock or
other equity interest in such Person.

                                  ARTICLE IX

                           The Administrative Agent

      SECTION 9.01. Authorization and Action. Each Lender hereby appoints and
authorizes Administrative Agent to take such action as Administrative Agent
deems appropriate on its behalf and to exercise such powers under this Agreement
and the other Loan Papers as are delegated to the Administrative Agent by the
terms of the Loan Papers, together with such powers as are reasonably incidental
thereto. As to any matters not expressly provided for by this Agreement and the
other Loan Papers (including, without limitation, enforcement or collection of
the Notes), Administrative Agent shall not be required to exercise any
discretion or take any action, but shall be required to act or to refrain from
acting (and shall be fully protected in so acting or refraining from acting)
upon the instructions of Majority Lenders (or all Lenders, if required under
Section 10.01), and such instructions shall be binding upon all Lenders;
provided, however, that Administrative Agent shall not be required to take any
action which exposes Administrative Agent to personal liability or which is
contrary to any Loan Papers or applicable Law. Administrative Agent agrees to
give to each Lender notice of each notice given to it by the Borrower pursuant
to the terms of this Agreement and to distribute to each applicable Lender in
like funds all amounts delivered to Administrative Agent by the Borrower for the
Ratable or individual account of any Lender.

      SECTION 9.02. Administrative Agent's Reliance, Etc. Neither Administrative
Agent, nor any of its directors, officers, agents, employees, or representatives
shall be liable for any action taken or omitted to be taken by it or them under
or in connection with this Agreement or any other Loan Paper, except for its or
their own gross negligence or willful misconduct. Without limitation of the
generality of the foregoing, Administrative Agent (a) may treat the payee of any
Note as the holder thereof until Administrative Agent receives written notice of
the assignment or transfer thereof signed by such payee and in form satisfactory
to Administrative Agent; (b) may consult with legal counsel (including counsel
for the Parent, the Borrower or any of their Subsidiaries), 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 any other Loan Papers; (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 any other Loan Papers on the part of the
Borrower, the Parent or their Subsidiaries or to inspect the Property (including
the books and records) of the Borrower, the Parent or their Subsidiaries; (e)
shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement,
any other Loan Papers, or any other instrument or document furnished pursuant
hereto; and (f) shall incur no liability under or in respect of this Agreement
or any other Loan Papers by acting upon any notice, consent, certificate or
other instrument or writing believed by it to be genuine and signed or sent by
the proper party or parties.

      SECTION 9.03. Bank of America, N. A. and Affiliates. With respect to its
Commitment, its Advances, its Specified Percentage and any Loan Papers, Bank of
America, N. A. has the same Rights under this Agreement as any other Lender and
may exercise the same as though it were not Administrative Agent. Bank of
America, N. A. and its Affiliates may accept deposits

                                       70
<PAGE>   76

from, lend money to and generally engage in any kind of business with, any of
the Borrower, the Parent or any of their Subsidiaries, any Affiliate thereof,
and any Person who may do business therewith, all as if Bank of America, N. A.
were not Administrative Agent and without any duty to account therefor to any
Lender.

      SECTION 9.04. Lender Credit Decision. Each Lender acknowledges that it
has, independently and without reliance upon Administrative Agent or any other
Lender, and based on the financial statements referred to in Section 6.04 hereof
and such other documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon
Administrative 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 and the
other Loan Papers.

      SECTION 9.05. Indemnification by Lenders. Lenders shall indemnify
Administrative Agent, Ratably, 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 Administrative Agent in any way relating to
or arising out of any Loan Papers or any action taken or omitted by
Administrative Agent thereunder, including any negligence of Administrative
Agent; provided, however, 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 Administrative Agent's gross
negligence or willful misconduct. Without limitation of the foregoing, Lenders
shall reimburse Administrative Agent, Ratably, promptly upon demand for any
out-of-pocket expenses (including reasonable attorneys' fees) incurred by
Administrative Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiation, legal proceedings or otherwise) of, or legal and other advice in
respect of rights or responsibilities under, the Loan Papers. The indemnity
provided in this Section 9.05 shall survive the termination of this Agreement.

      SECTION 9.06. Successor Administrative Agent. Administrative Agent may
resign at any time by giving written notice thereof to Lenders and the Borrower,
and may be removed at any time with or without cause by the action of all
Lenders (other than Administrative Agent, if it is a Lender). Upon any such
resignation, Majority Lenders shall have the right to appoint a successor
Administrative Agent with the prior written consent of the Borrower (which shall
not be unreasonably withheld, provided further that no such consent shall be
required after the occurrence of and during the continuance of any Default or
Event of Default). If no successor Administrative Agent shall have been so
appointed and shall have accepted such appointment within thirty days after the
retiring Administrative Agent's giving of notice of resignation, then the
retiring Administrative Agent may, on behalf of Lenders, appoint a successor
Administrative Agent, which shall be a commercial bank organized under the Laws
of the United States of America or of any State thereof and having a combined
capital and surplus of at least $50,000,000. Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall thereupon succeed to and become
vested with all the Rights

                                       71
<PAGE>   77

and duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations under the Loan Papers,
provided that if the retiring or removed Administrative Agent is unable to
appoint a successor Administrative Agent, Administrative Agent shall, after the
expiration of a sixty day period from the date of notice, be relieved of all
obligations as Administrative Agent hereunder. Notwithstanding any
Administrative Agent's resignation or removal hereunder, the provisions of this
Article IX shall continue to inure to its benefit as to any actions taken or
omitted to be taken by it while it was Administrative Agent under this
Agreement.

                                   ARTICLE X

                                 Miscellaneous

      SECTION 10.01. Waivers; Amendment.

      (a) Neither this Agreement nor any provision hereof or in any other Loan
Paper may be waived, amended or modified except pursuant to an agreement or
agreements in writing entered into by the Borrower and the Administrative Agent,
with the consent of the Majority Lenders; provided, however, that no such
agreement shall (i) decrease the principal amount of, or extend the maturity of,
or any scheduled principal payment date, or date for the payment of any interest
on the Loan, or waive or excuse any such payment or any part thereof, or
decrease the rate of interest on the Loan, decrease the Commitment Fee, the
Letter of Credit fee or any other fees owing hereunder, without the prior
written consent of each Lender affected thereby, (ii) release any material
Collateral or guaranty of the Obligations, provided that, the Administrative
Agent may, at the Borrower's request and without the consent of any Lender,
release (A) any immaterial portion of the Collateral that is immaterial to the
business of the Parent, the Borrower and their Subsidiaries, and (B) any portion
of the Collateral permitted by the terms of this Agreement to be sold or
disposed of (in an IRU or otherwise) in accordance with the terms of Section
7.06 hereof (and so long as the Borrower confirms to the Administrative Agent
that it intends to comply with the terms of Section 2.06 hereof, and grant a
Lien on all newly acquired equipment in accordance with the terms of Section
2.16(b) hereof); (iii) amend or modify the provisions of this Section or the
definition of the terms "Available Commitment", "Commitment", "Unavailable
Commitment", "Specified Percentage" or "Majority Lenders", without the prior
written consent of each Lender; provided further that no such agreement shall
amend, modify or otherwise affect the rights or duties of the Administrative
Agent hereunder without the prior written consent of the Administrative Agent.
The Borrower may rely on the written representation by the Administrative Agent
that consent of the Majority Lenders was obtained.

      (b) No failure or delay of the Administrative Agent or any Lender in
exercising any power or right hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Administrative Agent and the
Lenders hereunder are cumulative and are not exclusive of any rights or remedies
that they would otherwise have. No waiver of any provision

                                       72
<PAGE>   78

of this Agreement or any other Loan Paper, or consent to any departure by the
Borrower therefrom shall in any event be effective unless the same shall be
permitted by paragraph (a) above, 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 the Borrower in any case shall entitle the Borrower to any
other or further notice or demand in similar or other circumstances.

      (c) if to a Lender, to it at its address (or telecopy number) set forth on
the signature pages hereto or in the Assignment and Acceptance pursuant to which
such Lender shall have become a party hereto.

All notices and other communications given to any party hereto in accordance

      SECTION 10.03. Binding Effect. This Agreement shall become effective when
it shall have been executed by the Borrower and the Administrative Agent and
when the Administrative Agent shall have received counterparts hereof which,

and thereafter shall be binding upon and inure to the benefit of the parties
hereto and their respective permitted successors and assigns.

      SECTION 10.04. Successors and Assigns.

      (a) Whenever in this Agreement or any other Loan Paper any of the parties
hereto is referred to, such reference shall be deemed to include the permitted
successors and assigns of such party, and all covenants, promises and agreements
by or on behalf of the Borrower, the Administrative Agent or the Lenders that

      (b) Each Lender may assign to one or more assignee (an "Assignee") all or
a portion of its interests, rights and obligations under this Agreement and the

be unreasonably withheld, must give its prior written consent to such assignment
and (y) the amount of the Loan of

                                       74
<PAGE>   80

the Assignment and Acceptance with respect to such assignment is delivered to
the Administrative Agent) shall not be less than $5,000,000 (or, if less, the
entire remaining amount of such Lender's Loan) and will not result in the
unassigned portion, if any, of the assigning Lender's Loan being less than
$5,000,000, (ii) the parties to each such assignment shall execute and deliver
to the Administrative Agent an Assignment and Acceptance, together with a
processing and recordation fee of $3,500 payable by the parties to the
Assignment and Acceptance (unless such fee is waived by the Administrative
Agent) and (iii) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an administrative questionnaire. From and after the later
of (i) the effective date specified in each Assignment and Acceptance and (ii)
delivery of such Assignment and Acceptance to the Administrative Agent, (A) the
assignee thereunder shall be a party hereto and, to the extent of the interest
assigned by such Assignment and Acceptance, have the rights and obligations of a
Lender under this Agreement and the other Loan Papers and (B) the assigning
Lender thereunder shall, to the extent of the interest assigned by such
Assignment and Acceptance, be released from its obligations under this Agreement
and the other Loan Papers (and, in the case of an Assignment and Acceptance
covering all or the remaining portion of an assigning Lender's rights and
obligations under this Agreement and the other Loan Papers, such Lender shall
cease to be a party hereto and to the Loan Papers, but shall continue to be
entitled to the benefits of Sections 2.07 and 9.05 hereof, as well as to any
Fees accrued for its account and not yet paid). The Borrower shall, at their

      (c) By executing and delivering an Assignment and Acceptance, the
assigning Lender thereunder and the assignee thereunder shall be deemed to
confirm to and agree with each other and the other parties hereto as follows:

the interest being assigned thereby free and clear of any adverse claim and that
its outstanding balance of its Loan in each case without giving effect to
assignments thereof which have nor become effective, are as set forth in such
Assignment and Acceptance; (ii) except as set forth in (i) above, such assigning
Lender makes no representation or warranty and assumes no responsibility with
respect to any statements, warranties or representations made in or in
connection with this Agreement or any other Loan Paper, or the execution,
legality, validity, enforceability, genuineness, sufficiency or value of this
Agreement or any other Loan Paper, or any other instrument or document furnished
pursuant hereto, or the financial condition of the Parent, the Borrower or any
of their Subsidiaries, or the performance or observance by the Parent, the
Borrower or any of their Subsidiaries of any of its obligations under this
Agreement or any other Loan Paper, or any other instrument or document furnished
pursuant hereto; (iii) such assignee represents and warrants that it is legally
authorized to enter into such Assignment and Acceptance; (iv) such assignee
confirms that it has received a copy of this Agreement, together with copies of
the most recent financial statements referred to in Section 4.05 or delivered
pursuant to Section 6.04 and such other documents and information as it has
deemed appropriate to make its own credit analysis and decision to enter into
such Assignment and Acceptance; (v) such assignee will independently and without
reliance upon the Administrative Agent, such assigning Lender 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 and the other Loan Papers; (vi) such assignee
appoints and authorizes the Administrative Agent to take such action as agent on
its

                                       75
<PAGE>   81

behalf and to exercise such powers under this Agreement and the other Loan
Papers as are delegated to the Administrative Agent by the terms hereof and
thereof, together with such powers as are reasonably incidental thereto; and
(vii) such assignee agrees that it will perform in accordance with their terms
all the obligations which by the terms of this Agreement and the other Loan
Papers are required to be performed by it as a Lender.

      (d) Each Lender may without the consent of the Borrower or the
Administrative Agent sell participations to one or more banks or other entities
in all or a portion of its rights and obligations under this Agreement and the
other Loan Papers (including all or a portion of its Loan owing to it);
provided, however, that (i) such Lender's obligations under this Agreement and
the other Loan Papers shall remain unchanged, (ii) such Lender shall remain
solely responsible to the other parties hereto for the performance of such
obligations, (iii) the participating banks or other entities shall be entitled
to the benefit of the cost protection provisions contained in Sections 2.06
hereof to the same extent as if they were Lenders, provided that, such
participant shall not be entitled to any greater benefit of such Section than
the Lenders selling such participation interest has at the time and (iv) the
Borrower, the Administrative Agent and the Lenders shall continue to deal solely
and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the other Loan Papers, and such Lender
shall retain the sole right to enforce the obligations of the Borrower relating
to the Loan and to approve any amendment, modification or waiver of any
provision of this Agreement and the other Loan Papers (other than amendments,
modifications or waivers decreasing any fees payable hereunder or the amount of
principal of or the rate at which interest is payable on the Loan, extending any
scheduled principal payment date or date fixed for the payment of interest on
the Loan).

      (e) Any Lender or participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
10.04 disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrower furnished to such Lender by
or on behalf of the Borrower.

      (f) Any Lender may at any time assign all or any portion of its rights
under this Agreement and the other Loan Papers to a Federal Reserve Bank to

provided that no such assignment shall release a Lender from any of its
obligations hereunder or substitute any such Bank for such Lender as a party
hereto.

      (g) The Borrower shall not assign or delegate any of its rights or duties
hereunder without the prior written consent of the Administrative Agent and each
Lender, and any attempted assignment without such consent shall be null and
void.

      SECTION 10.05. Expenses; Indemnity.

      (a) The Borrower agrees to pay all reasonable out-of-pocket expenses
(other than income taxes or amounts relating to income taxes) incurred by the
Administrative Agent in connection with the syndication of the credit facilities
provided for herein and the preparation and administration of this Agreement and
the other Loan Papers or in connection with any amendments, modifications or
waivers of the provisions hereof (whether or not the transactions hereby or
thereby contemplated

                                       76
<PAGE>   82

shall be consummated) or incurred by the Administrative Agent or any Lender in
connection with the enforcement or protection of its rights in connection with
this Agreement and the Loan Papers, or in connection with the Loan made
hereunder, including the reasonable fees, charges and disbursements of Special
Counsel for the Administrative Agent, and, in connection with any such
enforcement or protection, the reasonable fees, charges and disbursements of any
other counsel for the Administrative Agent or any Lender.

      (b) The Borrower agrees to indemnify the Administrative Agent, each
Lender, each Affiliate of any of the foregoing Persons and each of their
respective directors, officers, employees and agents (each such Person being
called an "Indemnitee") against, and to hold each Indemnitee harmless from, any
and all losses, claims, damages, liabilities and related expenses, including
reasonable counsel fees, charges and disbursements (but excluding income taxes
and amounts relating to income taxes), incurred by or asserted against any
Indemnitee arising out of, in any way connected with, or as a result of (i) the
execution or delivery of this Agreement and the other Loan Papers or any
agreement or instrument contemplated thereby, the performance by the parties
thereto of their respective obligations thereunder or the consummation of the
Transactions and the other transactions contemplated thereby (other than those
matters raised exclusively by a participant against the Administrative Agent or
any Lender and not the Borrower and related solely to such party's actions),
(ii) the use of the proceeds of the Loan or (iii) any claim, litigation,
investigation or proceeding relating to any of the foregoing, whether or not any
Indemnitee is a party thereto; provided that with respect to such indemnity,
such indemnity shall not, as to any Indemnitee, be available to the extent that
such losses, claims, damages, liabilities or related expenses are determined by
a court of competent jurisdiction by final and nonappealable judgment to have
resulted from the gross negligence or wilful misconduct of, or breach of
contract by, such Indemnitee.

      (c) The provisions of this Section 10.05 shall remain operative and in
full force and effect regardless of the expiration of the term of this
Agreement, the other Loan Papers, the consummation of the transactions
contemplated hereby, the repayment of any of the Loan, the invalidity or
unenforceability of any term or provision of this Agreement, any other Loan
Paper, or any investigation made by or on behalf of the Administrative Agent,
any Lender. All amounts due under this Section 10.05 shall be payable on written
demand therefor.

      SECTION 10.06. Right of Setoff. If an Event of Default shall have occurred
and be continuing, each Lender is hereby authorized at any time and from time to
time, to the fullest extent permitted by Law, to set off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by such Lender to or for the
credit or the account of the Borrower against any of and all the obligations of
the Borrower now or hereafter existing under this Agreement and the other Loan
Papers held by such Lender, irrespective of whether or not such Lender shall
have made any demand under this Agreement and although such obligations may be
unmatured. Each Lender shall promptly notify the Borrower after any such set off
and application. The rights of each Lender under this Section 10.06 are in
addition to other rights and remedies (including other rights of setoff) which
such Lender may have.

                                       77
<PAGE>   83

      SECTION 10.07. Applicable Law. THIS AGREEMENT AND THE OTHER LOAN PAPERS
SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF
NEW YORK (EXCEPT, IN THE CASE OF CERTAIN OF THE OTHER LOAN PAPERS, TO THE EXTENT
THE LAWS OF ANOTHER JURISDICTION GOVERN THE PERFECTION AND EFFECT OF PERFECTION
OR NON-PERFECTION OF, CERTAIN LIENS).

      SECTION 10.08. Survival of Agreement. All covenants, agreements,
representations and warranties made by the Borrower herein and in the
certificates or other instruments prepared or delivered in connection with or
pursuant to this Agreement and the other Loan Papers shall be considered to have
been relied upon by the Lenders and shall survive the making by the Lenders of
the Loan, regardless of any investigation made by the Lenders, or on their
behalf, and shall continue in full force and effect as long as the principal of
or any accrued interest on the Loan or any Fee or any other amount payable under
this Agreement or any other Loan Paper is outstanding and unpaid. The provisions
of Sections 2.06 and 10.05 hereof shall remain operative and in full force and
effect regardless of the expiration of the term of this Agreement, the
consummation of the transactions contemplated hereby, the repayment of any
portion of the Loan, the invalidity or unenforceability of any term or provision
of this Agreement or any other Loan Paper, or any investigation made by or on
behalf of the Administrative Agent or any Lender.

      SECTION 10.09. Interest Rate Limitation. It is not the intention of any
party to any Loan Papers to make an agreement violative of the Laws of any
applicable jurisdiction relating to usury. In no event shall the Borrower or any
other Person be obligated to pay any amount in excess of the Maximum Amount. If
the Administrative Agent or any Lender ever receives, collects or applies, as
interest, any such excess, such amount which would be excessive interest shall
be deemed a partial repayment of principal and treated hereunder as such; and if
principal is paid in full, any remaining excess shall be paid to the Borrower or
the other Person entitled thereto. In determining whether or not the interest
paid or payable, under any specific contingency, exceeds the Maximum Amount, the
Parent, the Borrower and each of their Subsidiaries, the Administrative Agent
and each Lender shall, to the maximum extent permitted under Applicable Law, (a)
characterize any nonprincipal payment as an expense, fee or premium rather than
as interest, (b) exclude voluntary prepayments and the effect thereof, and (c)
amortize, prorate, allocate and spread in equal parts, the total amount of
interest throughout the entire contemplated term of the Obligations so that the
interest rate is uniform throughout the entire term of the Obligations; provided
that if the Obligations are paid and performed in full prior to the end of the
full contemplated term thereof, and if the interest received for the actual
period of existence thereof exceeds the Maximum Amount, the Administrative Agent
or Lenders, as appropriate, shall refund to the Borrower the amount of such
excess or credit the amount of such excess against the total principal amount
owing, and, in such event, neither the Administrative Agent nor any Lender shall
be subject to any penalties provided by any Laws for contracting for, charging
or receiving interest in excess of the Maximum Amount. This Section 10.09 shall
control every other provision of all agreements among the parties to the Loan
Papers pertaining to the transactions contemplated by or contained in the Loan
Papers.

      SECTION 10.10. ENTIRE AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN PAPERS
REPRESENT THE FINAL AGREEMENT BETWEEN THE

                                       78
<PAGE>   84

PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENT OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS
BETWEEN THE PARTIES.

      SECTION 10.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF,
UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN PAPER. EACH PARTY
HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER
PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT,
IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT AND THE OTHER LOAN PAPERS BY, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.11.

      SECTION 10.12. Severability. In the event any one or more of the
provisions contained in this Agreement or in any other Loan Paper should be held
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 (it being understood that the
invalidity of a particular provision in a particular jurisdiction shall not in
and of itself affect the validity of such provision in any other jurisdiction).
The parties shall endeavor in good-faith negotiations to replace the invalid,
illegal or unenforceable provisions with valid provisions the economic effect of
which comes as close as possible to that of the invalid, illegal or
unenforceable provisions.

      SECTION 10.13. Counterparts. This Agreement may be executed in
counterparts (and by different parties hereto on different counterparts), each
of which shall constitute an original but all of which when taken together shall
constitute a single contract, and shall become effective as provided in Section
10.03 hereof. Delivery of an executed signature page to this Agreement by
facsimile transmission shall be as effective as delivery of a manually signed
counterpart of this Agreement.

      SECTION 10.14. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

      SECTION 10.15. Jurisdiction; Consent to Service of Process.

      (a) The Borrower, the Administrative Agent and each Lender hereby
irrevocably and unconditionally submits, for itself and its property, to the
nonexclusive jurisdiction of any New York State court or Federal court of the
United States of America sitting in New York, New York and any appellate court
from any thereof, in any action or proceeding arising out of or relating to this
Agreement or any other Loan Paper, or for recognition or enforcement of any
judgment, and each of the parties hereto hereby irrevocably and unconditionally
agrees that all claims in respect of any

                                       79
<PAGE>   85

such action or proceeding may be heard and determined in such New York State or,
to the extent permitted by Law, in such Federal court. Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by Law. Nothing in this Agreement or in any other
Loan Paper shall affect any right that the Administrative Agent or any Lender
may otherwise have to bring any action or proceeding relating to this Agreement
or any other Loan Paper against the Borrower or its properties in the courts of
any jurisdiction.

      (b) The Borrower, the Administrative Agent and each Lender hereby
irrevocably and unconditionally waives, to the fullest extent it may legally and
effectively do so, any objection which it may now or hereafter have to the
laying of venue of any suit, action or proceeding arising out of or relating to
this Agreement or any other Loan Paper in any New York State or Federal court.
Each of the parties hereto hereby irrevocably waives, to the fullest extent
permitted by Law, the defense of an inconvenient forum to the maintenance of
such action or proceeding in any such court.

      (c) Each party to this Agreement and any other Loan Paper irrevocably
consents to service of process in the manner provided for notices in Section
10.02 hereof. Nothing in this Agreement or any other Loan Paper will affect the
right of any party to this Agreement or any other Loan Paper to serve process in
any other manner permitted by Law.

      SECTION 10.16. Release of Collateral. Promptly after payment in full of
all of the Obligations, the Administrative Agent and the Lenders hereby agree
that they will (a) execute all reasonable releases and UCC-3's necessary to
release all of the Lenders' Liens on the Collateral and (b) deliver all of the
Pledged Stock, together with the stock powers, if any, to the applicable
pledgors or as otherwise directed by the Borrower, and return the Note to the
Borrower marked "canceled" or "paid" or, at the Borrower's request and expense,
assign this Agreement and any or all Loan Papers to such party as the Borrower
may direct, in writing. Promptly upon payment in full of all of the Obligations,
this Agreement shall terminate.

      SECTION 10.17. Amendment, Restatement, Extension, Renewal and Increase.
This Agreement is a renewal and amendment and restatement of the Original Credit
Agreement, and, as such, all terms and provisions supersede in their entirety
the Original Credit Agreement. All subordination agreements, security
agreements, pledge agreements, mortgages, deeds of trust and other documents and
instruments granting any security interest or assigning any interest in any
assets of the Parent, the Borrower or any of their Subsidiaries to secure the
Obligation executed and delivered in connection with this Agreement that restate
any previously granted interest shall supersede any subordination agreements,
security agreements, pledge agreements, mortgages, deeds of trust and other
documents and instruments granting any security interest or assigning any
interest in any assets of the Parent, the Borrower or their Subsidiaries that
were executed and delivered in connection with the Original Credit Agreement
(the "Original Security Documents"), except for the Liens created under the
Original Security Documents which shall remain valid, binding and enforceable
Liens against the Parent, the Borrower, their Subsidiaries and each of the other
Persons granting any such Liens as amended by this Agreement and the other Loan
Papers. All other Original Security Documents shall continue to secure the
Obligations as herein defined, and shall be in full force and effect as amended
by this Agreement and the other Loan Papers.
