and prepayment by the Borrower of principal of or interest on Loans of a
particular Type shall be made to the Administrative Agent for the account of the
Lenders holding Loans of such Type pro rata in accordance with the respective
unpaid principal amounts of such Loans held by such Lenders; and (d) Interest
Periods for Loans of a particular Type shall be allocated among the Lenders
holding Loans of such Type pro rata according to the respective principal
amounts held by such Lenders.

     Section 3.3  Sharing of Payments, Etc.  If a Lender shall obtain payment of
                  -------------------------
any principal of or interest on any of the Obligations due to such Lender
hereunder through the exercise of any right of setoff, banker's lien,
counterclaim or similar right, or otherwise, it shall promptly purchase from the
other Lenders participations in the Obligations held by the other Lenders in
such amounts, and make such adjustments from time to time, as shall be equitable
to the end that all the Lenders shall share pro rata in accordance with the
unpaid principal and interest on the Obligations then due to each of them. To
such end, all of the Lenders shall make appropriate adjustments among themselves
(by the resale of participations sold or otherwise) if all or any portion of
such excess payment is thereafter rescinded or must otherwise be restored. Each
of the Loan Parties agrees, to the fullest extent it may effectively do so under
applicable law, that any Lender so purchasing a participation in the Obligations
by the other Lenders may exercise all rights of setoff, banker's lien,
counterclaim or similar rights with respect to such participation as fully as if
such Lender were a direct holder of Obligations in the amount of such
participation. Nothing contained herein shall require any Lender to exercise any
such right or shall affect the right of any Lender to exercise, and retain the
benefits of exercising, any such right with respect to any other indebtedness,
liability or obligation of any of the Loan Parties.

     Section 3.4  Non-Receipt of Funds by the Administrative Agent.  Unless the
                  ------------------------------------------------
Administrative Agent shall have been notified by a Lender or the Borrower (the
"Payor") prior to the date on which such Lender is to make payment to the
Administrative Agent of the proceeds of a Loan to be made by it hereunder or the
Borrower is to make a payment to the Administrative Agent for the account of one
or more of the Lenders, as the case may be (such payment being herein called the
"Required Payment"), which notice shall be effective upon receipt, that the
Payor does not intend to make the Required Payment to the Administrative Agent,
the Administrative Agent may assume that the Required Payment has been made and
may, in reliance upon such assumption (but shall not be required to), make the
amount thereof available to the intended recipient on such date and, if the
Payor has not in fact made the Required Payment to the Administrative Agent, the
recipient of such payment shall, on demand, pay to the Administrative Agent the
amount made available to it together with interest thereon in respect of the
period commencing on the date such amount was so made available by the
Administrative Agent until the date the Administrative Agent recovers such
amount at a rate per annum equal to the Federal Funds Rate for such period.

     Section 3.5  Taxes.

                                       41
<PAGE>

     (a)  All payments by the Borrower and/or any Guarantor of principal of and
interest on the Loans and of all fees and other amounts payable under the Loan
Documents shall be made free and clear of, and without withholding or deduction
by reason of, any present or future taxes, levies, duties, imposts, assessments
or other charges levied or imposed by any Governmental Authority (other than
franchise taxes and taxes on the overall net income of any Lender). If any such
taxes, levies, duties, imposts, assessments or other charges are so levied or
imposed, the Borrower will (i) make additional payments in such amounts so that
every net payment of principal of and interest on the Loans and of all other
amounts payable by it under the Loan Documents, after withholding or deduction
for or on account of any such present or future taxes, levies, duties, imposts,
assessments or other charges (including any tax imposed on or measured by net
income of a Lender attributable to payments made to or on behalf of a Lender
pursuant to this Section 3.5 and any penalties or interest attributable to such
                 -----------
payments), will not be less than the amount provided for herein or therein
absent such withholding or deduction (provided that the Borrower shall not have
any obligation to pay such additional amounts to any Lender to the extent that
such taxes, levies, duties, imposts, assessments or other charges are levied or
imposed by reason of the failure of such Lender to comply with the provisions of
Section 3.6), (ii) make such withholding or deduction and (iii) remit the full
-----------
amount deducted or withheld to the relevant Governmental Authority in accordance
with applicable law. Without limiting the generality of the foregoing, the
Borrower will, upon written request of any Lender, reimburse each such Lender
for the amount of (A) such taxes, levies, duties, imports, assessments or other
charges so levied or imposed by any Governmental Authority and paid by such
Lender as a result of payments made by the Borrower under or with respect to the
Loans other than such taxes, levies, duties, imports, assessments and other
charges previously withheld or deducted by the Borrower which have previously
resulted in the payment of the required additional amount to such Lender, and
(B) such taxes, levies, duties, assessments and other charges so levied or
imposed with respect to any Lender reimbursement under the foregoing clause (A),
so that the net amount received by such Lender (net of payments made under or
with respect to the Loans) after such reimbursement will not be less than the
net amount such Lender would have received if such taxes, levies, duties,
assessments and other charges on such reimbursement had not been levied or
imposed. The Borrower shall furnish promptly to the Administrative Agent for
distribution to each affected Lender, as the case may be, upon request of such
Lender, official receipts evidencing any such payment, withholding or reduction.

     (b)  The Borrower will indemnify the Administrative Agent and each Lender
(without duplication) against, and reimburse the Administrative Agent and each
Lender for, all present and future taxes, levies, duties, imposts, assessments
or other charges (including interest and penalties) levied or collected (whether
or not legally or correctly imposed, assessed, levied or collected), excluding,
however, any income or franchise taxes imposed on the overall net income or
receipts of the Administrative Agent or such Lender or any lending office of the
Administrative Agent or such Lender by any jurisdiction in which the
Administrative Agent or such Lender or any such lending office is located, on or
in respect of this Agreement, any of the Loan Documents or the Obligations or
any portion thereof (the "reimbursable taxes"). Any such indemnification shall
be on an after-tax basis, taking into account any such reimbursable taxes
imposed on the amounts paid as indemnity.

     (c)  Without prejudice to the survival of any other term or provision of
this Agreement, the obligations of the Borrower and the Guarantors under this
Section 3.5 shall survive the payment of the Loans and the other Obligations and
-----------
termination of the Commitments.

     Section 3.6  Withholding Tax Exemption.  Each Lender that is not
                  -------------------------
incorporated or otherwise formed under the laws of the U.S. or a state thereof
agrees that it will, prior to or on or about the Effective Date or the date upon
which it initially becomes a party to this Agreement, deliver to the Borrower
and the Administrative Agent two duly completed copies of U.S. Internal Revenue
Service Form W-8ECI or W-8BEN or other equivalent successor documents, as
appropriate, certifying in any case that such Lender is entitled to receive
payments from the Borrower under any Loan Document without deduction or
withholding of any U.S. federal income taxes.  Each Lender which so delivers a
Form W-8ECI or W-8BEN or other equivalent successor document, as appropriate,
further undertakes to deliver to the Borrower and the Administrative Agent two
additional copies of such form (or a successor form) on or before the date such
form expires or becomes obsolete or after the occurrence of any event requiring
a change in the most recent form so delivered by it, and such amendments thereto
or extensions or renewals thereof as may be reasonably requested by the Borrower
or the Administrative Agent, in each case certifying that such Lender is
entitled to receive payments from the Borrower under any Loan Document without
deduction or withholding of any U.S. federal income taxes, unless an event
(including without limitation any change in treaty, law or regulation) has
occurred prior to the date on which any such delivery would otherwise be
required which renders all such forms inapplicable or which would prevent such
Lender from duly completing and delivering any such form with respect to it and
such Lender advises the Borrower and the Administrative Agent that it is not
capable of receiving such payments without any deduction or withholding of U.S.
federal income tax.

     Section 3.7  Reinstatement of Obligations.  Notwithstanding anything to the
                  ----------------------------
contrary contained in this Agreement or any other Loan Document, if the payment
of any amount of principal of or interest with respect to the Loans or any other
amount of the Obligations, or any portion thereof, is rescinded, voided or must
otherwise be refunded by the Administrative Agent or any Lender upon the
insolvency, bankruptcy or reorganization of any Loan Party or otherwise for any
reason whatsoever, then each of (a) the Obligations, (b) the Loan Documents
(including, without limitation, this Agreement, the Notes and the Security
Documents), (c) the indebtedness, liabilities and obligations of the Borrower
and any other Loan Parties and (d) all Liens for the benefit of the
Administrative Agent and the Lenders created under or evidenced by the Loan
Documents, will be automatically reinstated and become automatically effective
and in full force and effect, all to the extent that and as though such payment
so rescinded, voided or otherwise refunded had never been made.

     Section 4.1  Additional Costs.
                  ----------------

     (a)  The Borrower shall pay directly to each Lender from time to time,
promptly upon the request of such Lender, the costs incurred by such Lender
which such Lender determines are attributable to its making or maintaining of
any Eurodollar Loans or its obligation to make any of such Loans, or any
reduction in any amount receivable by such Lender hereunder in respect of any

                                       43
<PAGE>

such Loans or obligations (such increases in costs and reductions in amounts
receivable being herein called "Additional Costs"), resulting from any
Regulatory Change which:

          (i)    changes the basis of taxation of any amounts payable to such
     Lender under this Agreement or its Notes in respect of any of such Loans
     (other than income or franchise taxes imposed on the overall net income or
     receipts of such Lender or its Applicable Lending Office for any of such
     Loans by the jurisdiction in which such Lender has its principal office or
     such Applicable Lending Office);

          (ii)   imposes or modifies any reserve, special deposit, minimum
     capital, capital ratio or similar requirement relating to any extensions of
     credit or other assets of, or any deposits with or other liabilities or
     commitments of, such Lender (excluding the Eurodollar Reserve Percentage to
     the extent it is included in the calculation of Eurodollar Basis); or

          (iii)  imposes any other condition affecting this Agreement or the
     Notes or any extensions of credit or liabilities or commitments
     contemplated hereunder or thereunder.

Each Lender will notify the Borrower (with a copy to the Administrative Agent)
of any event occurring after the Effective Date which will entitle such Lender
to compensation pursuant to this Section 4.1(a) as promptly as practicable after
                                 --------------
it obtains knowledge thereof and determines to request such compensation, and
(if so requested by the Borrower) will designate a different Applicable Lending
Office for the Eurodollar Loans of such Lender if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
sole opinion of such Lender, violate any law, rule or regulation or be in any
way disadvantageous to such Lender, provided that such Lender shall have no
obligation to so designate an Applicable Lending Office located in the U.S.
Each Lender will furnish the Borrower with a certificate setting forth the basis
and the amount of each request of such Lender for compensation under this
Section 4.1(a).  If any Lender requests compensation from the Borrower under
--------------
this Section 4.1(a), the Borrower may, by notice to such Lender (with a copy to
     --------------
the Administrative Agent), suspend the obligation of such Lender to make or
Continue making, or Convert Base Rate Loans into, Eurodollar Loans until the
Regulatory Change giving rise to such request ceases to be in effect (in which
case the provisions of Section 4.4 hereof shall be applicable).
                       -----------

     (b)  Without limiting the effect of the foregoing provisions of this

Section 4.1, in the event that, by reason of any Regulatory Change, any Lender
-----------
either (i) incurs Additional Costs based on or measured by the excess above a
specified level of the amount of a category of deposits or other liabilities of
such Lender which includes deposits by reference to which the interest rate on
Eurodollar Loans is determined as provided in this Agreement or a category of
extensions of credit or other assets of such Lender which includes Eurodollar
Loans or (ii) becomes subject to restrictions on the amount of such a category
of liabilities or assets which it may hold, then, if such Lender so elects by
notice to the Borrower (with a copy to the Administrative Agent), the obligation
of such Lender to make or Continue making, or Convert Base Rate Loans into,
Eurodollar Loans hereunder shall be suspended until such Regulatory Change
ceases to be in effect (in which case the provisions of Section 4.4 hereof shall
                                                        -----------
be applicable).

     (c)  Determinations and allocations by any Lender for purposes of this
Section 4.1 of the effect of any Regulatory Change on its costs of maintaining
-----------
its obligation to make Loans or of

                                       44
<PAGE>

making or maintaining Loans or on amounts receivable by it in respect of Loans
and of the additional amounts required to compensate such Lender in respect of
any Additional Costs, shall be conclusive in the absence of manifest error,
provided that such determinations and allocations are made on a reasonable
basis. Notwithstanding anything to the contrary contained herein, the Borrower
shall not be required to make any payment of Additional Costs to any Lender
pursuant to this Section 4.1 with respect to Additional Costs relating to any
                 -----------
period of time which is more than 120 days prior to such Lender's request for
such Additional Costs, provided that the foregoing provisions of this sentence
shall not apply to Additional Costs attributable to any Regulatory Change which
takes effect retroactively.

     Section 4.2  Limitation on Types of Loans.  Anything herein to the contrary
                  ----------------------------
notwithstanding, if with respect to any Eurodollar Loans for any Interest Period
therefor:

     (a)  the Administrative Agent determines (which determination shall be
conclusive absent manifest error) that quotations of interest rates for the
relevant deposits referred to in the definition of "Eurodollar Rate" in Section
                                                                        -------
1.1 hereof are not being provided in the relative amounts or for the relative
---
maturities for purposes of determining the rate of interest for such Loans as
provided in this Agreement; or

     (b)  the Required Lenders determine (which determination shall be
conclusive absent manifest error) and notify the Administrative Agent that the
relevant rates of interest referred to in the definition of "Eurodollar Rate" in
Section 1.1 hereof on the basis of which the rate of interest for such Loans for
-----------
such Interest Period is to be determined do not accurately reflect the cost to
the Lenders of making or maintaining such Loans for such Interest Period;

then the Administrative Agent shall give the Borrower prompt notice thereof and,
so long as such condition remains in effect, the Lenders shall be under no
obligation to make Eurodollar Loans or to Convert Base Rate Loans into
Eurodollar Loans and the Borrower shall, on the last day(s) of the then current
Interest Period(s) for the outstanding Eurodollar Loans, either prepay such
Loans or Convert such Loans into Base Rate Loans in accordance with the terms of
this Agreement.

     Section 4.3  Illegality.  Notwithstanding any other provision of this
                  ----------
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to (a) honor its obligation to make Eurodollar Loans
or (b) maintain Eurodollar Loans, then such Lender shall promptly notify the
Borrower (with a copy to the Administrative Agent) thereof and such Lender's
obligation to make or maintain Eurodollar Loans and to Convert Base Rate Loans
into Eurodollar Loans hereunder shall be suspended until such time as such
Lender may again make and maintain Eurodollar Loans (in which case the
provisions of Section 4.4 hereof shall be applicable).
              -----------

     Section 4.4  Treatment of Affected Loans.  If the obligation of any Lender
                  ---------------------------
to make or Continue, or to Convert Base Rate Loans into, Eurodollar Loans is
suspended pursuant to Section 4.1 or 4.3 hereof, such Lender's Eurodollar Loans
                      -----------    ---
shall be automatically Converted into Base Rate Loans on the last day(s) of the
then current Interest Period(s) for the Eurodollar Loans (or, in the case of a
Conversion required by Section 4.1(b) or 4.3 hereof, on such earlier date as
                       --------------    ---
such Lender may specify to the Borrower with a copy to the Administrative Agent)
and, unless and until such Lender gives notice as provided below that the
circumstances specified in Section 4.1 or 4.3 hereof which gave rise to such
                           -----------    ---
Conversion no longer exist:

                                       45
<PAGE>

     (a)  to the extent that such Lender's Eurodollar Loans have been so
Converted, all payments and prepayments of principal which would otherwise be
applied to such Lender's Eurodollar Loans shall be applied instead to its Base
Rate Loans; and

     (b)  all Loans which would otherwise be made or Continued by such Lender as
Eurodollar Loans shall be made as or Converted into Base Rate Loans and all
Loans of such Lender which would otherwise be Converted into Eurodollar Loans
shall be Converted instead into (or shall remain as) Base Rate Loans.

     If such Lender gives notice to the Borrower that the circumstances
specified in Section 4.1 or 4.3 hereof which gave rise to the Conversion of such
             -----------
Lender's Eurodollar Loans pursuant to this Section 4.4 no longer exist (which
                                           -----------
such Lender agrees to do promptly upon such circumstances ceasing to exist) at a
time when Eurodollar Loans are outstanding, such Lender's Base Rate Loans shall
be automatically Converted, on the first day(s) of the next succeeding Interest
Period(s) for such outstanding Eurodollar Loans, to the extent necessary so
that, after giving effect thereto, all Loans held by the Lenders holding
Eurodollar Loans and by such Lender are held pro rata (as to principal amounts,
Types and Interest Periods) in accordance with their respective Commitments.

     Section 4.5  Compensation.  The Borrower shall pay to the Administrative
                  ------------
Agent for the account of each Lender, promptly upon the request of such Lender
through the Administrative Agent, such amount or amounts as shall be sufficient
(in the reasonable opinion of such Lender) to compensate it for any loss, cost
or expense incurred by it as a result of:

     (a)  Any payment, prepayment or Conversion of a Eurodollar Loan for any
reason (including, without limitation, the acceleration of the outstanding Loans
pursuant to Section 11.2) on a date other than the last day of an Interest
            ------------
Period for such Loan; or

     (b)  Any failure by the Borrower for any reason (including, without
limitation, the failure of any conditions precedent specified in Article 6 to be
satisfied) to borrow, Convert or prepay a Eurodollar Loan on the date for such
borrowing, Conversion or prepayment specified in the relevant notice of
borrowing, prepayment or Conversion under this Agreement.

     Section 4.6  Capital Adequacy.  If, after the Effective Date, any Lender
                  ----------------
shall have determined that the adoption or implementation of any applicable law,
rule or regulation regarding capital adequacy (including, without limitation,
any law, rule or regulation implementing the Basle Accord), or any change
therein, or any change in the interpretation or administration thereof by any
central bank or other Governmental Authority charged with the interpretation or
administration thereof, or compliance by such Lender (or its parent) with any
guideline, request or directive regarding capital adequacy (whether or not
having the force of law) of any central bank or other Governmental Authority
(including, without limitation, any guideline or other requirement implementing
the Basle Accord), has or would have the effect of reducing the rate of return
on such Lender's (or its parent's) capital as a consequence of its obligations
hereunder or the transactions contemplated hereby to a level below that which
such Lender (or its parent) could have achieved but for such adoption,
implementation, change or compliance (taking into consideration such Lender's
policies with respect to capital adequacy) by an amount reasonably deemed by
such Lender to be material, then from time to time, within ten Business Days
after demand by such Lender (with a copy

                                       46
<PAGE>

to the Administrative Agent), the Borrower shall pay to such Lender such
additional amount or amounts as will compensate such Lender (or its parent) for
such reduction. A certificate of such Lender claiming compensation under this
Section 4.6 and setting forth the additional amount or amounts to be paid to it
-----------
hereunder shall be conclusive absent manifest error, provided that the
determination thereof is made on a reasonable basis. In determining such amount
or amounts, such Lender may use any reasonable averaging and attribution
methods. Notwithstanding anything to the contrary contained herein, the Borrower
shall not be required to make any payment of additional amounts to any Lender
pursuant to this Section 4.6 with respect to additional amounts relating to any
                 -----------
period of time which is more than 120 days prior to such Lender's request for
such additional amounts, provided that the foregoing provisions of this sentence
shall not apply to additional amounts attributable to any Regulatory Change
which takes effect retroactively.

     Section 4.7  Replacement of Lenders.    If at any time a Lender becomes a
                  -----------------------
Gross Up Lender, the Borrower shall have the right to replace such Lender with
another Person; provided that (a) such other Person shall be an Eligible
Assignee and such other Person shall execute an Assignment and Acceptance, (b)
neither the Administrative Agent nor any Lender shall have any obligation to the
Borrower to find such other Person, (c) in the event of a replacement of a Gross
Up Lender, in order for the Borrower to be entitled to replace such Lender, such
replacement must take place no later than 180 days after the date the Gross Up
Lender shall notify the Borrower and the Administrative Agent of its desire to
be paid any amounts pursuant to Section 3.5, 4.1 or 4.6, and (d) if the Borrower
                                ----------------    ---
replaces one Gross Up Lender, it must replace all Gross Up Lenders or replace
all Gross Up Lenders on a pro rata basis.  Each Lender agrees to its replacement
at the option of the Borrower pursuant to this Section 4.7 and in accordance
                                               -----------
with Section 13.8; provided that the successor Lender shall purchase without
     ------------
recourse such Lender's interest in the Obligations owed to such Lender for cash
in an aggregate amount equal to the aggregate unpaid principal thereof, all
unpaid interest accrued thereon, all unpaid commitment fees accrued for the
account of such Lender, any breakage costs incurred by the selling Lender
because of the prepayment of any Eurodollar Loans, all other fees (if any)
applicable thereto and all other amounts (including any amounts under this
Article 4) then owing to such Lender hereunder or under any other Loan Document
and the Loan Parties shall execute a release addressed to such Lender releasing
such Lender from all claims arising in connection with the Loan Documents.

Loan Parties (if and to the extent that it has Properties that are capable of
being covered by the following insurance) will maintain:

          (i)   Property Insurance.  Insurance against loss or damage covering
                ------------------

     improvements of such Person by reason of any Peril (as defined below) in

     to avoid the insured named therein from becoming a co-insurer of any loss
     under such policy, but in any event in such amounts as are reasonably
     available as determined by the Borrower's independent insurance broker
     reasonably acceptable to the Administrative Agent.

Subsidiaries shall purchase and maintain in effect all-risk, property and
casualty insurance (including casualty insurance covering earthquake and flood
damage) covering all tangible, real and personal Property (including, without
limitation, the Service Area Network and related equipment) and liability
insurance covering the operations of the Borrower and its Subsidiaries, in each
case in such amounts (not to exceed the greater of original cost or fair market
value) and as otherwise reasonably acceptable to the Administrative Agent and
the Required Lenders.  Such insurance shall be written by financially
responsible companies selected by the Borrower and having an A.M. Best Rating of
"A-" or better and being in a financial size category of "VI" or larger, or by
other companies reasonably acceptable to the Administrative Agent.  Each policy

benefit of itself and the other Lenders) as loss payee (with respect to casualty
insurance policies) and additional insured (with respect to liability insurance
policies) and shall provide that it will not be canceled, amended or reduced
except after not less than 30 days' prior written notice to the Administrative
Agent and shall also provide that the interests of the Administrative Agent and
the Lenders shall not be invalidated or reduced by any act, omission or

amendment.  For purposes hereof, the term "Peril" shall mean, collectively,
fire, lightning, flood, windstorm, hail, explosion, riot and civil commotion,
vandalism and malicious mischief, damage from aircraft, vehicles and smoke and
other perils covered by the "all-risk" endorsement then in use in the
jurisdictions where the Properties of the Loan Parties are located.

     (b)  Each of the Loan Parties will cause each Insurance Recovery (other
than any portion of an Insurance Recovery payable to a landlord to repair or
replace Property leased by the Borrower or any of its Subsidiaries) payable by
any insurance company to be deposited promptly with the Administrative Agent as
security for the Obligations if a Default has then occurred and is continuing,

Administrative Agent or its representatives may, at any time and from time to
time at the Borrower's expense, conduct field exams to verify the Borrowing Base
and for such other purposes as the Administrative Agent may reasonably request,
provided, however, that such field exams shall be at the Borrower's expense only
--------  -------
if a Default has then occurred and is continuing and there shall be no more than
one such field exam during any fiscal year unless a Default has occurred and is
continuing.  Without limiting the generality of the foregoing, the

or terms contained in this Agreement, the Loan Parties and the Required Lenders
agree to amend any such affected terms and provisions so as to reflect such

thereunder, (e) may consult with legal counsel (including counsel for any Loan
Party), 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, and
(f) shall incur no liability under or in respect of any Loan Document by acting
upon any notice, consent, certificate or other instrument or writing reasonably
believed by it to be genuine and signed or sent by the proper party or parties.
As to any matters not expressly provided for by this Agreement, the
Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, hereunder in accordance with instructions signed by the
Required Lenders, and such instructions of the Required Lenders and any action
taken or failure to act pursuant thereto shall be binding on all of the Lenders;
provided, however, that the Administrative Agent shall not be required to take
any action which exposes the Administrative Agent to liability or which is
contrary to this Agreement or any other Loan Document or applicable law. The
Administrative Agent shall not be deemed to have any fiduciary relationship with
any Lender or any Loan Party, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or otherwise exist against the Administrative Agent. Without limiting
the generality of the foregoing, the use of the term "agent" in this Agreement
with respect to the Administrative Agent is not intended to connote any
fiduciary or other express or implied obligation arising under agency doctrine
of any applicable law; instead, such term is used merely as a matter of market
custom and is intended to create or reflect only an administrative relationship
among independent contracting parties.

     Section 12.2  Rights of Administrative Agent as a Lender.  With respect to
                   ------------------------------------------
its Commitments, the Loans made by it and the Note(s) issued to it, the
Administrative Agent in its capacity as a Lender hereunder shall have the same
rights and powers hereunder as any other Lender and may exercise the same as
though it were not acting as the Administrative Agent, and the term "Lender" or
"Lenders" shall, unless the context otherwise indicates, include the
Administrative Agent in its individual capacity. The Administrative Agent and
its Affiliates may (without having to account therefor to any Lender) accept
deposits from, lend money to, act as trustee under indentures of, provide
merchant banking services to, own securities of, and generally engage in any
kind of banking, trust or other business with, any Loan Party or any of its
Affiliates and any other Person who may do business with or own securities of
the Borrower or any of its Affiliates, all as if it were not acting as the
Administrative Agent and without any duty to account therefor to the Lenders.

     Section 12.3  Defaults.  The Administrative Agent shall not be deemed to
                   --------
have knowledge or notice of the occurrence of a Default (other than the non-
payment of principal of or interest on the Loans or of commitment fees) unless
the Administrative Agent has received notice from a Lender

                                       95
<PAGE>

or the Borrower specifying such Default and stating that such notice is a
"notice of default". In the event that the Administrative Agent receives such a
notice of the occurrence of a Default, the Administrative Agent shall give
prompt notice thereof to the Lenders (and shall give each Lender prompt notice
of each such non-payment). The Administrative Agent shall (subject to Section
                                                                      -------
12.1) take such action with respect to such Default as shall be directed by the
----
Required Lenders, provided that unless and until the Administrative Agent shall
have received such directions, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default as it shall seem advisable and in the best interest of the
Lenders.

     Section 12.4  INDEMNIFICATION.  EACH LENDER HEREBY AGREES TO INDEMNIFY THE
                   ---------------
ADMINISTRATIVE AGENT FROM AND HOLD THE ADMINISTRATIVE AGENT HARMLESS AGAINST (TO
THE EXTENT NOT REIMBURSED UNDER SECTIONS 13.1 AND 13.2, BUT WITHOUT LIMITING THE
                                -------------     ----
OBLIGATIONS OF THE BORROWER UNDER SECTIONS 13.1 AND 13.2), RATABLY IN ACCORDANCE
                                  -------------     ----
WITH ITS PRO RATA SHARE (CALCULATED ON THE BASIS OF ITS COMMITMENT PERCENTAGE OF
THE AGGREGATE COMMITMENTS), ANY AND ALL LIABILITIES (INCLUDING, WITHOUT
LIMITATION, ENVIRONMENTAL LIABILITIES), OBLIGATIONS, LOSSES, DAMAGES, PENALTIES,
ACTIONS, JUDGMENTS, DEFICIENCIES, SUITS, COSTS, EXPENSES (INCLUDING ATTORNEYS'
FEES) AND DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED
ON, INCURRED BY OR ASSERTED AGAINST THE ADMINISTRATIVE AGENT IN ANY WAY RELATING
TO OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY ACTION TAKEN OR OMITTED TO
BE TAKEN BY THE ADMINISTRATIVE AGENT UNDER OR IN RESPECT OF ANY OF THE LOAN
DOCUMENTS; PROVIDED, FURTHER, THAT NO LENDER SHALL BE LIABLE FOR ANY PORTION OF
THE FOREGOING TO THE EXTENT CAUSED BY THE ADMINISTRATIVE AGENT'S GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT, IN ANY CASE, AS DETERMINED BY A FINAL, NON-
APPEALABLE JUDICIAL ORDER OF A COURT OF COMPETENT JURISDICTION. WITHOUT
LIMITATION OF THE FOREGOING, IT IS THE EXPRESS INTENTION OF THE LENDERS THAT THE
ADMINISTRATIVE AGENT SHALL BE INDEMNIFIED HEREUNDER FROM AND HELD HARMLESS
AGAINST ALL OF SUCH LIABILITIES (INCLUDING, WITHOUT LIMITATION, ENVIRONMENTAL
LIABILITIES), OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS,
DEFICIENCIES, SUITS, COSTS, EXPENSES (INCLUDING ATTORNEYS' FEES) AND
DISBURSEMENTS OF ANY KIND OR NATURE DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RESULTING FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE OF THE ADMINISTRATIVE AGENT
(EXCEPT TO THE EXTENT THE SAME ARE CAUSED BY THE ADMINISTRATIVE AGENT'S GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT, IN ANY CASE, AS DETERMINED BY A FINAL, NON-
APPEALABLE JUDICIAL ORDER OF A COURT OF COMPETENT JURISDICTION). WITHOUT
LIMITING ANY OTHER PROVISION OF THIS SECTION 12.4, EACH LENDER AGREES TO
                                     ------------
REIMBURSE THE ADMINISTRATIVE AGENT PROMPTLY UPON DEMAND FOR ITS PRO RATA SHARE
(CALCULATED ON THE BASIS OF ITS COMMITMENT PERCENTAGE OF THE AGGREGATE
COMMITMENTS) OF ANY AND ALL OUT-OF-POCKET EXPENSES (INCLUDING ATTORNEYS' FEES)
INCURRED BY THE ADMINISTRATIVE AGENT IN

                                       96
<PAGE>

CONNECTION WITH THE PREPARATION, EXECUTION, DELIVERY, ADMINISTRATION,
MODIFICATION, AMENDMENT OR ENFORCEMENT (WHETHER THROUGH NEGOTIATIONS, LEGAL
PROCEEDINGS OR OTHERWISE) OF, OR LEGAL ADVICE IN RESPECT OF RIGHTS OR
RESPONSIBILITIES UNDER, THE LOAN DOCUMENTS, TO THE EXTENT THAT THE
ADMINISTRATIVE AGENT IS NOT PROMPTLY REIMBURSED FOR SUCH EXPENSES BY THE
BORROWER.

     Section 12.5  Independent Credit Decisions.  Each Lender agrees that it has
                   ----------------------------
independently and without reliance on the Administrative Agent or any other
Lender, and based on such documents and information as it has deemed
appropriate, made its own credit analysis of the Borrower and the other Loan
Parties and its own decision to enter into this Agreement and that it will,
independently and without reliance upon the Administrative Agent or any other
Lender, and based upon such documents and information as it shall deem
appropriate at the time, continue to make its own analysis and decisions in
taking or not taking action under this Agreement or any of the other Loan
Documents. The Administrative Agent shall not be required to keep itself
informed as to the performance or observance by any Loan Party of this Agreement
or any other Loan Document or to inspect the Properties or books of any Loan
Party. Except for notices, reports and other documents and information expressly
required to be furnished to the Lenders by the Administrative Agent hereunder or
under the other Loan Documents, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other financial
information concerning the affairs, financial condition or business of any Loan
Party which may come into the possession of the Administrative Agent or any of
its Affiliates.

     Section 12.6  Several Commitments.  The Commitments and other obligations
                   -------------------
of the Lenders under this Agreement are several. The default by any Lender in
making a Loan in accordance with any of its Commitments shall not relieve the
other Lenders of their obligations under this Agreement. In the event of any
default by any Lender in making any Loan, each nondefaulting Lender shall be
obligated to make its Loan but shall not be obligated to advance the amount
which the defaulting Lender was required to advance hereunder.  In no event
shall any Lender be required to advance an amount or amounts with respect to any
of the Loans which would in the aggregate exceed such Lender's Commitment with
respect to such Loans.  No Lender shall be responsible for any act or omission
of any other Lender.

     Section 12.7  Successor Administrative Agent.  Subject to the appointment
                   ------------------------------
and acceptance of a successor Administrative Agent as provided below, the
Administrative Agent may resign at any time by giving notice thereof to the
Lenders and the Borrower.  Upon any such resignation, the Required Lenders will
have the right to appoint another Lender as a successor Administrative Agent.
If no successor Administrative Agent shall have been so appointed by the
Required Lenders and shall have accepted such appointment within 30 days after
the retiring Administrative Agent's giving of notice of resignation, then the
retiring Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be a commercial bank organized under the laws
of the U.S. or any state thereof or of a foreign country if acting through its
U.S. branch and having combined capital and surplus of at least $100,000,000.
If, at the time of the appointment of any successor Administrative Agent, a
Default has not occurred and is not continuing, then the successor
Administrative Agent shall not be appointed unless the identity of such
successor Administrative Agent is consented to by the Borrower, which consent
shall not be unreasonably withheld, conditioned or delayed. Upon the acceptance
of its appointment as successor

                                       97
<PAGE>

Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all rights, powers, privileges, immunities and
duties of the resigning Administrative Agent, and the resigning Administrative
Agent shall be discharged from its duties and obligations under this Agreement
and the other Loan Documents. After any Administrative Agent's resignation as
Administrative Agent, the provisions of this Article 12 shall continue in effect
for its benefit in respect of any actions taken or omitted to be taken by it
while it was the Administrative Agent. Each Administrative Agent (including each
successor Administrative Agent) agrees that, so long as it is acting as
Administrative Agent under this Agreement, it shall be a Lender under this
Agreement.

                                  ARTICLE 13

                                 Miscellaneous

     Section 13.1  Expenses.  The Borrower hereby agrees, on demand, to pay or
                   --------
reimburse the Administrative Agent and Nortel Networks Inc. (in its capacity as
the Original Administrative Agent) and, with respect to the matters referred to
in clauses (b) and (c) below, each of the other Lenders for paying: (a) all
reasonable out-of-pocket costs and expenses of the Administrative Agent accrued
in connection with the drafting, preparation, negotiation, execution and/or
delivery of this Agreement and the other Loan Documents, and any and all
waivers, amendments, modifications, renewals, extensions and supplements of or
to the Loan Documents, and the syndication of the Commitments and the Loans,
including, without limitation, the reasonable fees and expenses of legal counsel
(including all local counsel) for the Administrative Agent, (b) all out-of-
pocket costs and expenses of the Administrative Agent and the Lenders in
connection with any Default, the exercise of any right or remedy and the
enforcement of this Agreement or any other Loan Document or any term or
provision hereof or thereof, including, without limitation, the fees and
expenses of all legal counsel for the Administrative Agent and/or any Lender,
(c) all transfer, stamp, documentary or other similar taxes, assessments or
charges levied by any Governmental Authority in respect of this Agreement or any
of the other Loan Documents, (d) all costs, expenses, assessments and other
charges incurred in connection with any filing, registration, recording or
perfection of any Lien contemplated by this Agreement or any other Loan
Document, and (e) all reasonable out-of-pocket costs and expenses incurred by
the Administrative Agent in connection with due diligence, computer services,
copying, appraisals, environmental audits, collateral audits, field exams,
insurance, consultants and search reports.

     Section 13.2  INDEMNIFICATION.  EACH OF THE LOAN PARTIES HEREBY JOINTLY AND
                   ---------------
SEVERALLY AGREES TO INDEMNIFY THE ADMINISTRATIVE AGENT AND EACH LENDER AND EACH
AFFILIATE THEREOF AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, ATTORNEYS
AND AGENTS FROM, AND HOLD EACH OF THEM HARMLESS AGAINST, ANY AND ALL LOSSES,
LIABILITIES (INCLUDING, WITHOUT LIMITATION, ENVIRONMENTAL LIABILITIES), CLAIMS,
DAMAGES, PENALTIES, JUDGMENTS, DISBURSEMENTS, COSTS AND EXPENSES (INCLUDING
REASONABLE ATTORNEYS' AND CONSULTANTS' FEES) TO WHICH ANY OF THEM MAY BECOME
SUBJECT WHICH DIRECTLY OR INDIRECTLY ARISE FROM OR RELATE TO (A) THE
NEGOTIATION, EXECUTION, DELIVERY, PERFORMANCE, ADMINISTRATION OR ENFORCEMENT OF
ANY OF THE LOAN DOCUMENTS, INCLUDING, WITHOUT LIMITATION, THE EXERCISE OF ANY
FORECLOSURE RIGHT OR OTHER RIGHT OR REMEDY, (B) ANY

                                       98
<PAGE>

OF THE TRANSACTIONS CONTEMPLATED BY THE LOAN DOCUMENTS, (C) ANY BREACH BY ANY
LOAN PARTY OF ANY MATERIAL REPRESENTATION, WARRANTY, COVENANT OR OTHER AGREEMENT
CONTAINED IN ANY OF THE LOAN DOCUMENTS, (D) THE USE OR PROPOSED USE OF ANY LOAN,
(E) THE PRESENCE, RELEASE, THREATENED RELEASE, DISPOSAL, REMOVAL OR CLEANUP OF
ANY HAZARDOUS MATERIAL LOCATED ON, ABOUT, WITHIN OR AFFECTING ANY OF THE
PROPERTIES OF ANY LOAN PARTY OR ANY OF THEIR AFFILIATES, EXCEPT TO THE EXTENT
THAT THE LOSS, DAMAGE OR CLAIM IS THE RESULT OF GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF THE PERSON TO BE INDEMNIFIED, OR (F) ANY INVESTIGATION, LITIGATION
OR OTHER PROCEEDING, INCLUDING, WITHOUT LIMITATION, ANY THREATENED
INVESTIGATION, LITIGATION OR OTHER PROCEEDING RELATING TO ANY OF THE FOREGOING;
BUT EXCLUDING ANY OF THE FOREGOING TO THE EXTENT CAUSED BY THE GROSS NEGLIGENCE
OR WILLFUL MISCONDUCT OF THE PERSON TO BE INDEMNIFIED, IN ANY CASE, AS
DETERMINED BY A FINAL, NON-APPEALABLE JUDICIAL ORDER OF A COURT OF COMPETENT
JURISDICTION. WITHOUT LIMITING ANY PROVISION OF THIS AGREEMENT OR OF ANY OTHER
LOAN DOCUMENT, IT IS THE EXPRESS INTENTION OF THE PARTIES HERETO THAT EACH
PERSON TO BE INDEMNIFIED UNDER THIS SECTION 13.2 SHALL BE INDEMNIFIED FROM AND
                                    ------------
HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES (INCLUDING, WITHOUT
LIMITATION, ENVIRONMENTAL LIABILITIES), CLAIMS, DAMAGES, PENALTIES, JUDGMENTS,
DISBURSEMENTS, COSTS AND EXPENSES (INCLUDING REASONABLE ATTORNEYS' FEES) ARISING
OUT OF OR RESULTING FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE OF SUCH PERSON.
WITHOUT PREJUDICE TO THE SURVIVAL OF ANY OTHER TERM OR PROVISION OF THIS
AGREEMENT, THE OBLIGATIONS OF THE LOAN PARTIES UNDER THIS SECTION 13.2 SHALL
                                                          ------------
SURVIVE THE REPAYMENT OF THE LOANS AND OTHER OBLIGATIONS AND TERMINATION OF THE
COMMITMENTS.

     Section 13.3  Limitation of Liability.  None of the Administrative Agent,
                   -----------------------
any Lender or any Affiliate, officer, director, employee, attorney or agent
thereof shall be liable for any error of judgment or act done in good faith, or
be otherwise liable or responsible under any circumstances whatsoever (including
such Person's negligence), except for such Person's gross negligence or willful
misconduct.  None of the Administrative Agent, any Lender or any Affiliate,
officer, director, employee, attorney or agent thereof shall have any liability
with respect to, and each of the Borrower and the other Loan Parties hereby
waives, releases and agrees not to sue any of them upon, any claim for any
special, indirect, incidental or consequential damages suffered or incurred by
any Loan Party or any of its Affiliates in connection with, arising out of or in
any way related to this Agreement or any of the other Loan Documents, or any of
the transactions contemplated by this Agreement or any of the other Loan
Documents.  Each of the Loan Parties hereby waives, releases and agrees not to
sue the Administrative Agent or any Lender or any of their respective
Affiliates, officers, directors, employees, attorneys or agents for exemplary or
punitive damages in respect of any claim in connection with, arising out of or
in any way related to this Agreement or any of the other Loan Documents, or any
of the transactions contemplated by this Agreement or any of the other Loan
Documents.

     Section 13.4  No Duty.  All attorneys, accountants, appraisers and other
                   -------
professional Persons and consultants retained by the Administrative Agent and
the Lenders shall have the right to act exclusively in the interest of the
Administrative Agent and the Lenders and shall have no duty of disclosure, duty
of loyalty, duty of care or other duty or obligation of any type or nature
whatsoever to any Loan Party or any of its Affiliates or any other Person.

     Section 13.5  No Fiduciary Relationship.  The relationship between each
                   -------------------------
Loan Party and each Lender is solely that of debtor and creditor, and neither
the Administrative Agent nor any Lender has any fiduciary or other special
relationship with any Loan Party or any of its Affiliates, and no term or
condition of any of the Loan Documents shall be construed so as to deem the
relationship between any Loan Party and any Lender, or such Affiliate and any
Lender, to be other than that of debtor and creditor. No joint venture or
partnership is created by this Agreement among the Lenders or among any Loan
Party or any of its Affiliates and the Lenders.

     Section 13.6  Equitable Relief.  Each of the Loan Parties recognizes that,
                   ----------------
in the event it fails to pay, perform, observe or discharge any or all of the
Obligations, any remedy at law may prove to be inadequate relief to the
Administrative Agent and the Lenders. Each of the Loan Parties therefore agrees
that the Administrative Agent and the Lenders, if the Administrative Agent or
the Lenders so request, shall be entitled to temporary and permanent injunctive
relief in any such case without the necessity of proving actual damages.

     Section 13.7  No Waiver; Cumulative Remedies.  No failure on the part of
                   ------------------------------
the Administrative Agent or any Lender to exercise and no delay in exercising,
and no course of dealing with respect to, any right, power or privilege under
this Agreement or any other Loan Document shall operate as a waiver thereof, nor
shall any single or partial exercise of any right, power or privilege under this
Agreement or any other Loan Document preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. The rights and
remedies provided for in this Agreement and the other Loan Documents are
cumulative and not exclusive of any rights and remedies provided by law.

     Section 13.8  Successors and Assigns.
                   ----------------------

     (a)  This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns. Except as may result
by operation of law from mergers permitted pursuant to Section 9.3, neither the
                                                       -----------
Borrower nor any other Loan Party may assign or transfer any of its rights or
obligations under this Agreement or any other Loan Document without the prior
written consent of the Administrative Agent and the Lenders. Any Lender may sell
participations in all or a portion of its rights and obligations under this
Agreement and the other Loan Documents (including, without limitation, all or a
portion of its Commitments and the Loans owing to it); provided, however, that
(i) such Lender's obligations under this Agreement and the other Loan Documents
(including, without limitation, its Commitments) shall remain unchanged, (ii)
such Lender shall remain solely responsible to the Borrower for the performance
of such obligations, (iii) such Lender shall remain the holder of its Notes for
all purposes of this Agreement, (iv) the Borrower and the other Loan Parties
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
Documents, and (v) the Lenders shall not grant any participation under which the
participant shall have the right to approve (or under which the consent of the
participant must be obtained prior to the

                                      100
<PAGE>

Lenders' being able to approve) any amendment or waiver of this Agreement or the
other Loan Documents, except to the extent that such amendment or waiver (A)
increases any Commitment, (B) reduces the interest rate or the amount of
principal or fees applicable to the Loans or Commitments in which such
participant is participating, (C) extends any Maturity Date, (D) releases all or
substantially all of the Collateral (except as provided for herein or in any
other Loan Document) or any guaranty of the Obligations, or (E) releases any
Loan Party from its monetary Obligations under any of the Loan Documents.

     (b)  The Loan Parties and each of the Lenders agree that any Lender (the
"Assigning Lender") may, with the consent of the Administrative Agent and, prior
to the occurrence of and during the continuation of Default, the consent of the
Borrower, which consents will not be unreasonably withheld, at any time assign
to one or more Eligible Assignees all or any part of its rights and/or
obligations under this Agreement and the other Loan Documents (including,
without limitation, its Commitments and/or Loans) (each an "Assignee");
provided, however, that (i) each such assignment may be of a varying percentage
of the Assigning Lender's rights and/or obligations under this Agreement and the
other Loan Documents and may relate to some but not all of such rights and/or
obligations, (ii) except in the case of (A) an assignment of all of a Lender's
rights and obligations under this Agreement and the other Loan Documents or (B)
an assignment by a Lender to an Affiliate of such Lender, to another Lender or
to an Approved Fund, the amount of the Commitment(s) and/or Loans of the
Assigning Lender being assigned pursuant to each assignment (determined as of
the date of the Assignment and Acceptance with respect to such assignment) shall
in no event be less than $5,000,000 calculated based upon the aggregate amount
of the Commitment(s) and/or Loans assigned, provided that the amount of the
Commitment(s) and/or Loans of the Assigning Lender being assigned to an
Affiliate of the Assigning Lender may be in such other amount not less than
$2,000,000 as may be agreed to by the Administrative Agent from time to time,
and (iii) the parties to each such assignment shall execute and deliver to the
Administrative Agent for its acceptance and recording in the Register (as
defined below), an Assignment and Acceptance, together with the Note subject to
such assignment, and a processing and recordation fee of $3,500.  Upon such
execution, delivery, acceptance and recording, from and after the effective date
specified in each Assignment and Acceptance, which effective date shall be at
least five Business Days after the execution thereof or such other date as may
be approved by the Administrative Agent, (1) the Assignee thereunder shall be a
party hereto as a "Lender" and, to the extent that rights and obligations
hereunder have been assigned to it pursuant to such Assignment and Acceptance,
have the rights and obligations of a Lender hereunder and under the Loan
Documents, and (2) the Assigning Lender thereunder shall, to the extent that
rights and obligations hereunder have been assigned by it pursuant to such
Assignment and Acceptance, relinquish its rights and be released from its
obligations under this Agreement and the other Loan Documents (and, in the case
of an Assignment and Acceptance covering all or the remaining portion of a
Lender's rights and obligations under the Loan Documents, such Lender shall
cease to be a party thereto, provided that such Lender's rights under Article 4,
Section 13.1 and Section 13.2 accrued through the date of assignment shall
------------     ------------
continue).

     (c)  By executing and delivering an Assignment and Acceptance, the
Assigning Lender thereunder and the Assignee thereunder confirm to and agree
with each other and the other parties hereto as follows: (i) other than as
provided in such Assignment and Acceptance, 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 the Loan
Documents or the

                                      101
<PAGE>

execution, legality, validity, enforceability, genuineness, sufficiency or value
of the Loan Documents or any other instrument or document furnished pursuant
thereto; (ii) such Assigning Lender makes no representation or warranty and
assumes no responsibility with respect to the financial condition or results of
operations of any Loan Party or any of its Affiliates or the performance or
observance by any Loan Party or any of its Affiliates of its obligations under
the Loan Documents; (iii) such Assignee confirms that it has received a copy of
the Loan Documents, together with copies of the financial statements referred to
in Section 7.2 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; (iv) such Assignee will, independently and without
reliance upon the Administrative Agent or such Assigning 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 Documents; (v) such Assignee confirms that it
is an Eligible Assignee; (vi) such Assignee appoints and authorizes the
Administrative Agent to take such action as agent on its behalf and exercise
such powers under the Loan Documents as are delegated to the Administrative
Agent by the terms 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 of the obligations which by the terms of the
Loan Documents are required to be performed by it as a Lender.

     (d)  The Administrative Agent shall maintain at its Principal Office a copy
of each Assignment and Acceptance delivered to and accepted by it and a register
for the recordation of the names and addresses of the Lenders and the
Commitments of, and principal amount of the Loans owing to, each Lender from
time to time (the "Register"). The entries in the Register shall be conclusive
and binding for all purposes, absent manifest error, and the Loan Parties, the
Administrative Agent and the Lenders may treat each Person whose name is
recorded in the Register as a Lender hereunder for all purposes under the Loan
Documents.  The Register shall be available for inspection by the Borrower or
any Lender at any reasonable time and from time to time upon reasonable prior
notice.

     (e)  Upon its receipt of an Assignment and Acceptance executed by an
Assigning Lender and Assignee representing that it is an Eligible Assignee,
together with the Note(s) subject to such assignment, the Administrative Agent
shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit A hereto, (i) accept such Assignment and
                          ---------
Acceptance, (ii) record the information contained therein in the Register, and
(iii) give prompt written notice thereof to the Borrower. Within five Business
Days after its receipt of such notice, the Borrower, at its expense, shall
execute and deliver to the Administrative Agent in exchange for each surrendered
Note evidencing the Loans assigned, a new Note evidencing such Loans payable to
the order of such Eligible Assignee in an amount equal to such Loans assigned to
it and, if the Assigning Lender has retained any Loans, a new Note evidencing
each such Loans payable to the order of the Assigning Lender in the amount of
such Loans retained by it (each such promissory note shall constitute a "Note"
for purposes of the Loan Documents).  Such new Notes shall be dated the
effective date of such Assignment and Acceptance and shall otherwise be in
substantially the form of Exhibit B hereto.
                          ---------

     (f)  Any Lender may, in connection with any assignment or participation or
proposed assignment or participation pursuant to this Section 13.8, disclose to
                                                      ------------
the Assignee or participant or proposed Assignee or participant any information
relating to any Loan Party or any of its Affiliates

                                      102
<PAGE>

furnished to such Lender by or on behalf of any Loan Party or any of its
Affiliates; provided that each such actual or proposed Assignee or participant
shall agree to be bound by the provisions of Section 13.20.
                                             -------------

     (g)  Any Lender may assign and pledge any Note held by it to any Federal
Reserve Bank or the U.S. Treasury as collateral security pursuant to Regulation
A of the Board of Governors of the Federal Reserve System and any operating
circular issued by such Federal Reserve System and/or Federal Reserve Bank;
provided, however, that any payment made by the Borrower for the benefit of such
assigning and/or pledging Lender in accordance with the terms of the Loan
Documents shall satisfy the Borrower's obligations under the Loan Documents in
respect thereof to the extent of such payment. No such assignment and/or pledge
shall release the assigning and/or pledging Lender from its obligations
hereunder.

     (h)  The Borrower shall maintain, or cause to be maintained, a register
(the "Registered Note Register") (which, at the request of the Borrower (which
request the Borrower makes by the execution of this Agreement) shall be kept by
the Administrative Agent on behalf of the Borrower at no extra charge to the
Borrower at the address to which notices to the Administrative Agent are to be
sent hereunder) on which it shall enter the name of the registered owner of each
of the Loans which is evidenced by a Registered Note.  Notwithstanding anything
to the contrary contained in this Section 13.8, a Registered Note and the Loans
                                  ------------
evidenced thereby may be assigned or otherwise transferred in whole or in part
only by registration of such assignment or transfer of such Registered Note and
the Loans evidenced thereby on the Registered Note Register (and each Registered
Note shall expressly so provide).  Any assignment or transfer of all or part of
such Loans and the Registered Note evidencing the same shall be registered on
the Registered Note Register only upon surrender for registration of assignment
or transfer of the Registered Note evidencing such Loans, duly endorsed by (or
accompanied by a written instrument of assignment or transfer duly executed by)
the registered noteholder thereof, and thereupon one or more new Registered
Notes in the same aggregate principal amount shall be issued to the designated
assignee(s) or transferee(s). Prior to the due presentment for registration of
transfer of any Registered Note, the Borrower and the other Loan Parties and the
Administrative Agent shall treat the Person in whose name such Loans and the
Registered Note(s) evidencing the same are registered as the owner thereof for
the purpose of receiving all payments thereon and for all other purposes,
notwithstanding any notice to the contrary. The Registered Note Register shall
be available for inspection by the Borrower and any Lender at any reasonable
time upon reasonable prior notice.

     (i)  None of the Loan Parties will become a party to any loan agreement,
credit agreement or similar agreement which restricts or prohibits the right or
ability of any lender which is a party thereto to become a Lender under this
Agreement.

     (j)  Holdings and the Borrower shall provide prompt assistance to the
Administrative Agent and the Lenders in connection with their respective efforts
in syndicating the Loans and Commitments.  Such assistance shall include making
senior officers and other representatives of Holdings and the Borrower and their
Affiliates available for meetings with prospective Lenders and providing, in a
timely manner, such assistance as may be reasonably requested by the
Administrative Agent or its advisors, including, without limitation, providing
information to and responding to inquiries from prospective Lenders with respect
to the business, operations, Business Plan, results and other matters relating
to the business of Holdings, the Borrower and the other Loan Parties.

hereunder or under the other Loan Documents, the obligations of the Borrower and
the other Loan Parties under Article 4 and Sections 13.1 and 13.2 shall survive

                    ----------
Agreement, the Notes or any other Loan Document to which any Loan Party is a
party, nor any consent to any departure by any Loan Party therefrom, shall in
any event be effective unless the same shall be agreed or consented to by the
Required Lenders and such Loan Party in writing, and each such waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given; provided, however, that no amendment, waiver or consent shall,
unless in writing and signed by all of the Lenders and the Borrower, do any of
the following: (a) increase the Commitments of the Lenders (or any Lender) or
subject the Lenders to any additional obligations; (b) reduce the principal of,

the failure by the Borrower to pay any sum due to any of the Lenders hereunder;
and provided, further, however, that no amendment, waiver or consent relating to
Sections 12.1, 12.2, 12.3, 12.4 or 12.5 shall require the agreement of the
-------------------------------    ----
Borrower or any other Loan Party.  Notwithstanding anything to the contrary

                  -------------

                                                                       -------

prior written consent of the Lenders that hold, at the time of such amendment,
waiver or consent, at least a majority (in Dollar amount) of the Tranche A
Commitments or Tranche B Commitments, respectively.

     Section 13.12  Maximum Interest Rate.
                    ---------------------

     (a)  No interest rate specified in this Agreement or any other Loan
Document shall at any time exceed the Maximum Rate. If at any time the interest
rate (the "Contract Rate") for any Obligation shall exceed the Maximum Rate,
thereby causing the interest accruing on such Obligation to be limited to the
Maximum Rate, then any subsequent reduction in the Contract Rate for such
Obligation shall not reduce the rate of interest on such Obligation below the
Maximum Rate until the aggregate amount of interest accrued on such Obligation
equals the aggregate amount of interest which would have accrued on such
Obligation if the Contract Rate for such Obligation had at all times been in
effect.

     (b)  Notwithstanding anything to the contrary contained in this Agreement
or the other Loan Documents, none of the terms and provisions of this Agreement
or the other Loan Documents shall ever be construed to create a contract or
obligation to pay interest at a rate in excess of the Maximum Rate; and neither
the Administrative Agent nor any Lender shall ever charge, receive, take,
collect, reserve or apply, as interest on the Obligations, any amount in excess
of the Maximum Rate. The parties hereto agree that any interest, charge, fee,
expense or other obligation provided for in this Agreement or in the other Loan
Documents which constitutes interest under applicable law shall be, ipso facto
and under any and all circumstances, limited or reduced to an amount equal to
the lesser of (i) the amount of such interest, charge, fee, expense or other
obligation that would be payable in the absence of this Section 13.12(b) or (ii)
                                                        ----------------
an amount, which when added to all other interest payable under this Agreement
and the other Loan Documents, equals the Maximum Rate.  If, notwithstanding the
foregoing, the Administrative Agent or any Lender ever contracts for, charges,
receives, takes, collects, reserves or applies as interest any amount in excess
of the Maximum Rate, such amount which would be deemed excessive interest shall
be deemed a partial payment or prepayment of principal of the Obligations and
treated hereunder as such; and if the Obligations, or applicable portions
thereof, are paid in full, any remaining excess shall promptly be paid to the
Borrower or other appropriate Loan Party.  In determining whether the interest
paid or payable, under any specific contingency, exceeds the Maximum Rate, the
Borrower and the other Loan Parties, the Administrative Agent and the Lenders
shall, to the maximum extent permitted by applicable law, (i) characterize any
nonprincipal payment as an expense, fee or premium rather than as interest, (ii)
exclude voluntary prepayments and the effects thereof, and (iii) amortize,
prorate, allocate and spread in equal or unequal parts the total amount of
interest throughout the entire contemplated term of the Obligations, or
applicable portions thereof, so that the interest rate does not exceed the
Maximum Rate at any time during the term of the Obligations; provided that, if
the unpaid principal balance is 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 Rate, the Administrative Agent
and/or the Lenders, as appropriate, shall refund to the Borrower or other
appropriate Loan Party the amount of such excess and, in such event, the
Administrative Agent and the Lenders shall not be subject to any penalties
provided by any laws for contracting for, charging, receiving, taking,
collecting, reserving or applying interest in excess of the Maximum Rate.

                                  iPCS, INC.
                             AMENDED AND RESTATED
                         2000 LONG TERM INCENTIVE PLAN
                         -----------------------------

     1.  History, Purpose and Effective Date.  iPCS, Inc. 2000 Long Term
         -----------------------------------
Incentive Plan (the "Plan") was adopted by the Board of Directors of iPCS, Inc.
("iPCS") on May 5, 2000 and was established to increase stockholder value and to
advance the interests of iPCS and its subsidiaries (collectively, the "Company")
by awarding equity and performance based incentives designed to attract, retain
and motivate employees, directors who are not employees of the Company and
consultants who perform services for the Company.  As used in the Plan, the term
"subsidiary" means any business, whether or not incorporated, in which iPCS has
an ownership interest. The following constitutes an amendment, restatement and
continuation of the Plan in the form of "iPCS, Inc.  Amended and Restated 2000
Long Term Incentive Plan", which amendment and restatement shall become
effective as of the date (the "Effective Date") it is adopted by the Board of
Directors of iPCS (the "Board"). The Plan shall be unlimited in duration and, in
the event of Plan termination, shall remain in effect as long as any Awards (as
defined in Section 3) under it are outstanding; provided, however, that no
Incentive Stock Options (as defined in subsection 5.1) may be granted under the
Plan on a date that is more than ten years from the date the Plan is adopted.

     2.  Administration.
         --------------

     2.1. Administration by Board or Committee.  The Plan shall be administered
          ------------------------------------
by the Compensation Committee of the Board (the "Committee"), which Committee
shall consist of two or more persons who constitute "non-employee directors"
within the meaning of Rule 16b-3 promulgated under the Securities Exchange Act
of 1934, as amended (the "Exchange Act") and "outside directors" within the
meaning of Treas. Reg. (S) 1.162-27(e)(3).   Notwithstanding the foregoing, the
Plan shall be administered by the Board with respect to Awards to directors who
are not employees of the Company and, with respect to such Awards, the term
"Committee" as used herein shall be deemed to refer to the Board.

     2.2. Authority.  Subject to the provisions of the Plan, the Committee shall
          ---------
have the authority to (a) manage and control the operation of the Plan, (b)
conclusively interpret and construe the provisions of the Plan, and prescribe,
amend and rescind rules, regulations and procedures relating to the Plan, (c)
make Awards under the Plan, in such forms and amounts and subject to such
restrictions, limitations and conditions as it deems appropriate, including,
without limitation, Awards which are made in combination with or in tandem with
other Awards (whether or not contemporaneously granted) or compensation or in
lieu of current or deferred compensation, (d) modify the terms of, cancel and
reissue, or repurchase outstanding Awards (including, but not limited to,
repurchasing or settling any Option (as defined in subsection 5.1) in cash upon
a Change in Control (as defined in subsection 11.2)), (e) prescribe the form of
agreement, certificate or other instrument evidencing any Award under the Plan,
(f) correct any defect or omission and reconcile any inconsistency in the Plan
or in any Award hereunder, (g)
<PAGE>

extend the exercise or vesting date of any Award under the Plan, (h) accelerate
the vesting or exercise date of any Award under the Plan, and (i) make all other
determinations and take all other actions as it deems necessary or desirable for
the implementation and administration of the Plan; provided, however, that only
after approval of the Board may the Committee cancel or modify any Option
granted for the purpose of reissuing an additional option to the option holder
at a lower exercise price. The determination of the Committee on matters within
its authority shall be conclusive and binding on the Company and all other
persons. The Committee's determinations under the Plan need not be uniform and
may be made selectively among persons who receive, or are eligible to receive,
Awards, whether or not such persons are similarly situated.

     2.3. Delegation to Officers.  Notwithstanding the foregoing provisions of
          ----------------------
this Section 2, the Committee, subject to the terms and conditions of the Plan,
may delegate to any officer of iPCS, if such individual is then serving as a
member of the Board, the authority to act as a subcommittee of the Committee for
purposes of making Awards under the Plan with respect to such number of shares
as the Committee shall designate annually, to such employees of the Company who
are not subject to section 16(a) of the Exchange Act as such officer shall
determine in his or her sole discretion, and such officer shall have the
authority and duties of the Committee with respect to such grants.

     3.   Participation.  Subject to the terms and conditions of the Plan, the
          -------------
Committee shall determine and designate, from time to time, from among the
employees, directors and consultants who provide services to the Company those
persons who will be granted one or more Awards under the Plan, and thereby
become "Participants" in the Plan.  In the discretion of the Committee, and
subject to the terms of the Plan, a Participant may be granted any Award
permitted under the provisions of the Plan, and more than one Award may be
granted to a Participant; provided, however, that Incentive Stock Options under
the Plan may only be awarded to employees of iPCS and its subsidiary
corporations (as defined in section 424(f) of the Internal Revenue Code of 1986,
as amended (the "Code")).  Except as otherwise agreed by the Committee and the
Participant, or except as otherwise provided in the Plan, an Award under the
Plan shall not affect any previous Award under the Plan or an award under any
other plan maintained by the Company.  For purposes of the Plan, the term
"Award" shall mean any award or benefit granted to any Participant under the
Plan.

     4.   Shares Subject to the Plan.
          --------------------------

     4.1. Number of Shares Reserved.  The shares of common stock of iPCS
          -------------------------
("Stock") with respect to which Awards may be made under the Plan shall be
shares currently authorized but unissued or currently held or subsequently
acquired by iPCS as treasury shares, including shares purchased in the open
market or in private transactions.  The aggregate maximum number of shares of
Stock which may be issued with respect to Awards under the Plan shall be
6,500,000 (subject to adjustments described in subsection 4.4) as increased on
December 31 of each year from and including December 31, 2000 by a number of
shares equal to one percent (1%) of the number of shares of Stock outstanding on
such date; provided, however, that any such increase

                                      -2-
<PAGE>

shall be made only to the extent that iPCS has sufficient authorized and
unreserved Stock for such purpose; and further provided that the maximum
aggregate number of shares to be issued under the Plan shall not exceed
8,000,000 (subject to adjustments described in subsection 4.4). Subject to the
maximum aggregate number of shares that may be issued under the Plan, the
increase provided by the preceding sentence shall be made each December 31,
regardless of the number of shares remaining available for issuance under the
Plan on such date.

     4.2. Individual Limits on Awards.  Notwithstanding any other provision of
          ---------------------------
the Plan to the contrary, the maximum aggregate number of shares of Stock that
may be granted or awarded to any Participant under the Plan for any calendar
year shall be 650,000 (as adjusted in accordance with subsection 4.4) and there
shall be no limit on cash payouts with respect to grants or awards under the
Plan in any calendar year to any Covered Employee (within the meaning of section
162(m) of the Code). The determination made under the foregoing provisions of
this subsection 4.2 shall be based on the shares subject to the Awards at the
time of grant, regardless of when the Awards become exercisable.

     4.3. Reusage of Shares.
          -----------------

     (a)  In the event of the termination (by reason of forfeiture, expiration,
          cancellation, surrender or otherwise) of any Award under the Plan,
          that number of shares of Stock that was subject to the Award but not
          delivered shall again be available for Awards under the Plan.

     (b)  In the event that shares of Stock are delivered under the Plan as a
          Stock Award (as defined in Section 7) and are thereafter forfeited or
          reacquired by iPCS pursuant to rights reserved upon the award thereof,
          such forfeited or reacquired shares shall again be available for
          Awards under the Plan.

     (c)  Notwithstanding the provisions of paragraphs (a) or (b), the following
          shares shall not be available for reissuance under the Plan: (i)
          shares with respect to which the Participant has received the benefits
          of ownership (other than voting rights), either in the form of
          dividends or otherwise; (ii) shares which are withheld from any Award
          or payment under the Plan to satisfy tax withholding obligations (as
          described in subsection 10.5); and (iii) shares which are surrendered
          to fulfill tax obligations (as described in subsection 10.5).

     4.4. Adjustments to Shares Reserved.  In the event of any merger,
          ------------------------------
consolidation, reorganization, recapitalization, spinoff, stock dividend, stock
split, reverse stock split, exchange or other distribution with respect to
shares of Stock or other change in the corporate structure or capitalization
affecting the Stock, the type and number of shares of Stock which are or may be
subject to Awards under the Plan (including the individual limits described in
subsection 4.2) and the terms of any outstanding Awards (including the price at
which shares of Stock may be issued pursuant to an outstanding award) shall be
equitably adjusted by the Committee, in its

                                      -3-
<PAGE>

sole discretion, to preserve the value of benefits awarded or to be awarded to
Participants under the Plan.

     5.  Options.
         -------

     5.1.   Definitions.  The grant of an "Option" under this Section 5 entitles
            -----------
the Participant to purchase shares of Stock at the Option Price (as defined in
subsection 5.3), subject to the terms of this Section 5.  Options granted under
this Section 5 may be either Incentive Stock Options or Non-Qualified Stock
Options, as determined in the discretion of the Committee.  An "Incentive Stock
Option" is an Option that is intended to satisfy the requirements applicable to
an "incentive stock option" described in section 422(b) of the Code.  A "Non-
Qualified Stock Option" is an Option that is not intended to be an "incentive
stock option" as that term is described in section 422(b) of the Code.

     5.2.   Restrictions Relating to Incentive Stock Options.  To the extent
            ------------------------------------------------
that the aggregate fair market value of Stock with respect to which Incentive
Stock Options are exercisable for the first time by any individual during any
calendar year (under all plans of iPCS and its subsidiaries (as defined in
section 424(f) of the Code)) exceeds $100,000, such options shall be treated as
Non-Qualified Stock Options, to the extent required by section 422 of the Code.

     5.3.   Option Price.  The price at which shares of Stock may be
            ------------
purchased upon the exercise of an Option (the "Option Price") shall be
established by the Committee or shall be determined by a method established by
the Committee at the time the Option is granted; provided, however, that in no
event shall such price be less than the greater of: (i) 100% of the Fair Market
Value (as defined in subsection 10.11) of a share of Stock as of the date on
which the Option is granted; or (ii) the par value of a share of Stock on such
date.

     5.4.   Vesting.  Unless otherwise designated by the Committee, an Option
            -------
shall become exercisable with respect to 6.25% of the shares of Stock subject
thereto at the conclusion of each 90 day period following the grant of such
Option.  Notwithstanding the foregoing, as provided in Section 11, unless
otherwise designated by the Committee all unvested, unexpired Options shall
fully vest immediately upon a Change in Control.

     5.5.   Termination of Service.  Unless otherwise designated by the
            ----------------------
Committee, in the event of termination of the Participant's employment or other
service with the Company unexercised, unexpired Options shall be affected as
follows:

     (a)    If a Participant's employment or other service terminates for any
            reason other than for cause, retirement, death, or disability (as
            each such term is defined in a written agreement between such
            Participant and iPCS, or if no such agreement exists, then as such
            terms are defined by the Committee from time to time), then all
            unexercised, unexpired Options, to the extent exercisable
            immediately before such termination, may be exercised in whole or in
            part, not later than the 90th day after such termination (but no
            later than the stated Expiration Date).

                                      -4-
<PAGE>

     (b)    If a Participant's employment or other service terminates due to
            retirement (any termination of employment after age 65 other than
            for cause) from the Company, then all unexercised, unexpired
            Options, whether or not exercisable on the date of such termination,
            would be exercisable in whole or in part within one year after such
            termination date (but no later than the stated Expiration Date).

     (c)    If a Participant's employment or other service terminates due to
            death or disability, then all unexercised, unexpired Options,
            whether or not exercisable on the date of such termination, may be
            exercised, in whole or in part, within six months after such
            termination (but no later than the stated Expiration Date). If such
            termination is due to death, the Option would be exercisable during
            the applicable period by the Participant's (i) personal
            representative or by the person to whom the Option is transferred by
            will or the applicable laws of descent and distribution, or (ii) a
            beneficiary designated in accordance with the Committee's rules.

     (d)    If a Participant's employment or other service is terminated by the
            Company for cause (as determined by the Committee), all Options
            (whether or not then exercisable) which the Participant holds will
            automatically terminate effective immediately upon such termination.

     (e)    Notwithstanding the foregoing, the Committee, in its sole
            discretion, may extend any of the time limits set forth in this
            Section 5.5 so as to permit any unexercised portion thereof to be
            exercised at any time within the time period established by the
            Committee. In no event shall the term of any Option be extended
            beyond the 10th anniversary of date an Option is granted.

     5.6.   Exercise.  Except as otherwise expressly provided in the Plan, an
            --------
Option may be exercised, in whole or in part, in accordance with terms and
conditions established by the Committee at the time of grant (or, if allowed by
the Plan, terms and conditions established by the Committee at any time prior to
date on which the Option is exercised); provided, however, that no Option shall
be exercisable after the Expiration Date (as defined in Section 9) applicable to
that Option.  The full Option Price of each share of Stock purchased upon the
exercise of any Option shall be paid at the time of such exercise (except that,
in the case of a cashless exercise arrangement approved by the Committee,
payment may be made as soon as practicable after the exercise) and, as soon as
practicable thereafter, a certificate representing the shares so purchased shall
be delivered to the person entitled thereto.  The Option Price shall be payable
in cash, in shares of Stock (valued at Fair Market Value as of the day of
exercise), in any combination of cash and Stock, pursuant to a cashless exercise
arrangement approved in advance by the Committee or pursuant to any other method
of payment approved in advance by the Committee. The exercise of an Option will
result in the surrender of the corresponding rights under a tandem Stock
Appreciation Right, if any.

                                      -5-
<PAGE>

     6.   Stock Appreciation Rights.
          -------------------------

     6.1. Definition.  Subject to the terms of this Section 6, a "Stock
          ----------
Appreciation Right" granted under the Plan entitles the Participant to receive,
in cash or Stock, value equal to all or a portion of the excess of: (a) the Fair
Market Value of a specified number of shares of Stock at the time of exercise;
over (b) a specified price which shall not be less than 100% of the Fair Market
Value of the Stock at the time the Stock Appreciation Right is granted, or, if
granted in tandem with an Option, the exercise price with respect to shares
under the tandem Option.

     6.2. Exercise.  If a Stock Appreciation Right is not in tandem with an
          --------
Option, then the Stock Appreciation Right shall be exercisable in accordance
with the terms established by the Committee in connection with such rights after
the Expiration Date applicable to that Stock Appreciation Right.  If a Stock
Appreciation Right is in tandem with an Option, then the Stock Appreciation
Right shall be exercisable at the time the tandem Option is exercisable.  The
exercise of a Stock Appreciation Right will result in the surrender of the
corresponding rights under the tandem Option.

     6.3. Settlement of Award.  Upon the exercise of a Stock Appreciation
          -------------------
Right, the value to be distributed to the Participant, in accordance with
subsection 6.1, shall be distributed in shares of Stock (valued at their Fair
Market Value at the time of exercise), in cash, or in a combination thereof, in
the discretion of the Committee.

     6.4. Post-Exercise Limitations.   The Committee, in its discretion, may
          -------------------------
impose such restrictions on shares of Stock acquired pursuant to the exercise of
a Stock Appreciation Right as it determines to be desirable, including, without
limitation, restrictions relating to disposition of the shares and forfeiture
restrictions based on service, performance, ownership of Stock by the
Participant, and such other factors as the Committee determines to be
appropriate.

     7.   Stock Awards.
          ------------

     7.1. Definition.  Subject to the terms of this Section 7, a "Stock Award"
          ----------
under the Plan is a grant of shares of Stock to a Participant, the earning,
vesting or distribution of which is subject to one or more conditions
established by the Committee. Such conditions may relate to events (such as
performance or continued service) occurring before or after the date the Stock
Award is granted, or the date the Stock is earned by, vested in or delivered to
the Participant. If the vesting of Stock Awards is subject to conditions
occurring after the date of grant, the period beginning on the date of grant of
a Stock Award and ending on the vesting or forfeiture of such Stock (as
applicable) is referred to as the "Restricted Period". Stock Awards may provide
for delivery of the shares of Stock at the time of grant, or may provide for a
deferred delivery date.

     7.2. Terms and Conditions of Awards.  Beginning on the date of grant (or,
          ------------------------------
 if later, the date of distribution) of shares of Stock comprising a Stock
Award, and including any applicable Restricted Period, the Participant, as owner
of such shares, shall have the right to vote such

                                      -6-
<PAGE>

shares; provided, however, that payment of dividends with respect to Stock
Awards shall be subject to the following:

     (a)  On and after the date that a Participant has a fully earned and vested
          right to the shares comprising a Stock Award, and the shares have been
          distributed to the Participant, the Participant shall have all
          dividend rights (and other rights) of a stockholder with respect to
          such shares.

     (b)  Prior to the date that a Participant has a fully earned and vested
          right to the shares comprising a Stock Award, the Committee, in its
          sole discretion, may award Dividend Rights (as defined below) with
          respect to such shares.

     (c)  On and after the date that a Participant has a fully earned and vested
          right to the shares comprising a Stock Award, but before the shares
          have been distributed to the Participant, the Participant shall be
          entitled to Dividend Rights with respect to such shares, at the time
          and in the form determined by the Committee.

A "Dividend Right" with respect to shares comprising a Stock Award shall entitle
the Participant, as of each dividend payment date, to an amount equal to the
dividends payable with respect to a share of Stock multiplied by the number of
such shares.  Dividend Rights shall be settled in cash or in shares of Stock, as
determined by the Committee, shall be payable at the time and in the form
determined by the Committee, and shall be subject to such other terms and
conditions as the Committee may determine.

     8.   Performance Units.
          -----------------

     8.1. Definition.  Subject to the terms of this Section 8, the Award of
          ----------
"Performance Units" under the Plan entitles the Participant to receive value for
the units at the end of a Performance Period to the extent provided under the
Award.  The number of units earned, and the value received for them, will be
contingent on the degree to which the performance measures established at the
time of grant of the Award are met.  For purposes of the Plan, the "Performance
Period" with respect to the award of any Performance Units shall be the period
over which the applicable performance is to be measured.

     8.2. Terms and Conditions of Awards.  For each Participant, the Committee
          ------------------------------
will determine the value of Performance Units, which may be stated either in
cash or in units representing shares of Stock; the performance measures used for
determining whether the Performance Units are earned; the Performance Period
during which the performance measures will apply; the relationship between the
level of achievement of the performance measures and the degree to which
Performance Units are earned; whether, during or after the Performance Period,
any revision to the performance measures or Performance Period should be made to
reflect significant events or changes that occur during the Performance Period;
and the number of earned Performance Units that will be paid in cash and the
number of earned Performance Units to be paid in shares of Stock.

                                      -7-

     8.3. Settlement.  Settlement of Performance Units shall be subject to
          ----------
          the following:

     (a)  The Committee will compare the actual performance to the performance
          measures established for the Performance Period and determine the
          number of units as to which settlement is to be made, and the value of
          such units.

     (b)  Settlement of units earned shall be wholly in cash, wholly in Stock or
          in a combination of the two, to be distributed in a lump sum or
          installments, as determined by the Committee.

     (c)  For Performance Units stated in units representing shares of Stock
          when granted, one share of Stock will be distributed for each unit
          earned, or cash will be distributed for each unit earned equal to
          either (A) the Fair Market Value of a share of Stock as of the last
          day of the Performance Period or (B) the average Stock value over a
          period determined by the Committee.

     (d)  For Performance Units stated in cash when granted, the value of each
          unit earned will be distributed in its initial cash value, or shares
          of Stock will be distributed based on the cash value of the units
          earned divided by (A) the Fair Market Value of a share of Stock at the
          end of the Performance Period or (B) the average Stock value over a
          period determined by the Committee.

     (e)  Shares of Stock distributed in settlement of the units shall be
          subject to such vesting requirements and other conditions, if any, as
          the Committee shall determine.

     8.4. Termination During Performance Period.  If a Participant's termination
          -------------------------------------
of employment or other service with the Company occurs during a Performance
Period with respect to any Performance Units granted to him, the Committee may
determine that the Participant will be entitled to settlement of all or any
portion of the Performance Units as to which he would otherwise be eligible, and
may accelerate the determination of the value and settlement of such Performance
Units or make such other adjustments as the Committee, in its sole discretion,
deems desirable.

     9.   Expiration of Awards.  The "Expiration Date" with respect to an Award
          --------------------
under the Plan means the date established as the Expiration Date by the
Committee at the time of the grant; provided, however, that the Expiration Date
with respect to any Award shall not be later than the ten-year anniversary of
the date on which the Award is granted.  If a Stock Appreciation Right is in
tandem with an Option, then the "Expiration Date" for the Stock Appreciation
Right shall be the Expiration Date for the related Option.

     10.    Miscellaneous.
            -------------

     10.1.  Compliance with Applicable Laws; Limits on Distribution.
            -------------------------------------------------------
Distribution of shares of Stock or other amounts under the Plan shall be subject
to the following:

     (a)    Notwithstanding any other provision of the Plan, iPCS shall have no
            liability to deliver any shares of Stock under the Plan or make any
            other distribution of benefits under the Plan unless such delivery
            or distribution would comply with all applicable laws and the
            applicable regulations or requirements of any securities exchange or
            similar entity.

     (b)    In the case of a Participant who is subject to Section 16(a) and
            16(b) of the Exchange Act, the Committee may, at any time, add such
            conditions and limitations to any Award to such Participant, or any
            feature of any such Award, as the Committee, in its sole discretion,
            deems necessary to comply with Section 16(a) or 16(b) of the
            Exchange Act and the rules and regulations thereunder or to obtain
            any exemption therefrom.

     (c)    To the extent that the Plan provides for issuance of certificates to
            reflect the transfer of shares of Stock, the transfer of such shares
            may be effected on a non-certificated basis, to the extent not
            prohibited by applicable law or the rules of any securities exchange
            or similar entity.

     (d)    Prior to the delivery of any shares of Stock under the Plan, if the
            Committee deems it necessary to comply with applicable securities
            laws, iPCS may require a written statement that the recipient is
            acquiring the shares for investment and not for the purpose or with
            the intention of distributing the shares and will not dispose of
            them in violation of the registration requirements of the Securities
            Act of 1933.

     10.2.  Performance-Based Compensation.  To the extent that the Committee
            ------------------------------
determines that it is necessary or desirable to conform any Awards under the
Plan with the requirements applicable to "Performance-Based Compensation", as
that term is used in section 162(m)(4)(C) of the Code, it may, at or prior to
the time an Award is granted, take such steps and impose such restrictions with
respect to such Award as it determines to be necessary or desirable.

     10.3.  Transferability.  Each Award granted hereunder shall not be
            ---------------
assignable or transferable other than by will or the laws of descent and
distribution and may be exercised, during the Participant's lifetime, only by
the Participant or his or her guardian or legal representative, except that a
Participant may in a manner and to the extent  permitted by the Committee (a)
designate in writing a beneficiary to exercise an Award after his or her death
(provided, however, that no such designation shall be effective unless received
by the office of iPCS designated for that purpose prior to the Participant's
death) and (b) if the Award expressly permits, transfer an Option (other than an
Incentive Stock Option) for no consideration to any (i) spouse, children or
grandchildren of the Participant (such individuals to be referred to as

                                      -9-
<PAGE>

"Immediate Family"), (ii) trust solely for the benefit of the Participant or any
or all members of the Participant's Immediate Family, (iii) partnership whose
only partners are the Participant or members of the Participant's  Immediate
Family, or (iv) revocable inter vivos trust of which the Participant is both the
settlor and a trustee; provided, however, that the transferee shall agree to be
subject to all of the terms and conditions applicable to such Award prior to
such transfer.

     10.4.  Notices.  Any notice or document required to be filed with the
            -------
Committee under the Plan will be properly filed if delivered or mailed by
registered mail, postage prepaid, to the Committee, in care of iPCS, at its
principal executive offices.  The Committee may, by advance written notice to
affected persons, revise such notice procedure from time to time.  Any notice
required under the Plan (other than a notice of election) may be waived by the
person entitled to notice.

     10.5.  Withholding.  The Company shall be entitled to deduct from any
            -----------
payment under the Plan the amount of any tax required by law to be withheld with
respect to such payment or may require any participant to pay such amount to the
Company prior to and as a condition of making such payment.  In addition, the
Committee may, in its discretion and subject to such rules as it may adopt from
time to time, permit a Participant to elect to have the Company withhold from
any payment under the Plan (or to have the Company accept from the participant),
for tax withholding purposes, shares of Stock, valued at their Fair Market
Value, but in no event shall the Fair Market Value of the number of shares so
withheld (or accepted) exceed the amount necessary to meet the minimum Federal,
state and local marginal tax rates then in effect that are applicable to the
Participant and to the particular transaction.

     10.6.  Form and Time of Elections.  Unless otherwise specified herein, each
            --------------------------
election required or permitted to be made by any Participant or other person
entitled to benefits under the Plan, and any permitted modification or
revocation thereof, shall be in writing filed with the Committee at such times,
in such form, and subject to such restrictions and limitations, not inconsistent
with the terms of the Plan, as the Committee shall require.

     10.7.  Agreement With iPCS.  At the time of an Award to a Participant under
            -------------------
the Plan, the Committee may require a Participant to enter into an agreement
with iPCS (the "Agreement") in a form specified by the Committee, agreeing to
the terms and conditions of the Plan and to such additional terms and
conditions, not inconsistent with the Plan, as the Committee may, in its sole
discretion, prescribe.

     10.8.  Limitation of Implied Rights.
            ----------------------------

     (a)    Neither a Participant nor any other person shall, by reason of the
            Plan, acquire any right in or title to any assets, funds or property
            of the Company whatsoever, including, without limitation, any
            specific funds, assets, or other property which the Company, in its
            sole discretion, may set aside in anticipation of a liability under
            the Plan. A Participant shall have only a contractual right to
            benefits or amounts, if any, payable under the Plan, unsecured by
            any assets of the Company.

                                     -10-
<PAGE>

            Nothing contained in the Plan shall constitute a guarantee by the
            Company that the assets of the Company shall be sufficient to pay
            any amounts or benefits to any person.

     (b)    The Plan does not constitute a contract of employment or continued
            service, and selection as a Participant will not give any person the
            right to be retained in the employ or service of the Company, nor
            any right or claim to any benefit or payment under the Plan, unless
            such right or claim has specifically accrued under the terms of the
            Plan. Except as otherwise provided in the Plan, no Award under the
            Plan shall confer upon the holder thereof any right as a stockholder
            of iPCS prior to the date on which he fulfills all service
            requirements and other conditions for receipt of such rights.

     10.9.  Evidence.  Evidence required of anyone under the Plan may be by
            --------
certificate, affidavit, document or other information that the person acting on
it considers pertinent and reliable, and signed, made or presented by the proper
party or parties.

     10.10. Gender and Number.  Where the context admits, words in one gender
            -----------------
shall include the other gender, words in the singular shall include the plural
and the plural shall include the singular.

     10.11. Definition of Fair Market Value.  For purposes of the Plan, the
            -------------------------------
"Fair Market Value" of a share of common stock of iPCS as of any date shall be
the closing market composite price for such Stock as reported on the Nasdaq
National Market on that date or, if Stock is not traded on that date, on the
immediately preceding date on which Stock was traded.  In the event that the
Stock is not listed for trading on a national exchange or quoted on an inter-
dealer quotation system, the Fair Market Value shall be determined by the
Committee.

     11.    Change in Control.
            -----------------

     11.1.  Acceleration. Except as otherwise provided in the Plan or the
            ------------
Agreement reflecting the applicable Award, the following shall occur immediately
upon a Change in Control:

     (a)     All outstanding Options (regardless of whether in tandem with Stock
             Appreciation Rights) and Stock Appreciation Rights (regardless of
             whether in tandem with Options) shall become fully exercisable.

     (b)     All Stock Awards shall become fully vested.

     (c)     Performance Units may be paid out in such manner and amounts as
             determined by the Committee.

                                     -11-
<PAGE>

     11.2.  Definition of Change in Control.  For purposes of the Plan, the
            -------------------------------
term "Change in Control" means a change in the beneficial ownership of the
voting stock of iPCS or a change in the composition of the Board as follows:

     (a)    any "Person" (as such term is used in Section 13(d) and 14(d)(2) of
            the Exchange Act), other than iPCS, any entity owned, directly or
            indirectly, by the stockholders of iPCS in substantially the same
            proportions as their ownership of stock of iPCS, and any trustee or
            other fiduciary holding securities under an employee benefit plan of
            iPCS or its subsidiaries or such proportionately owned corporation)
            becomes through acquisitions of securities of iPCS after the
            Effective Date of the Plan, the "beneficial owner" (as defined in
            Rule 13d-3 promulgated under the Exchange Act), directly or
            indirectly, of securities of iPCS representing 50% or more of the
            combined voting power of the then outstanding securities of iPCS
            having the right to vote for the election of directors;

     (b)    the stockholders of iPCS approve a merger or consolidation of iPCS
            with any other corporation, other than (A) a merger or consolidation
            which would result in the voting securities of iPCS outstanding
            immediately prior thereto continuing to represent (either by
            remaining outstanding or by being converted into voting securities
            of the surviving entity) more than 50% of the combined voting power
            of the voting securities of iPCS or such surviving entity
            outstanding immediately after such merger or consolidation, or (B) a
            merger or consolidation effected to implement a recapitalization of
            iPCS (or similar transaction) in which no Person acquires more than
            15% of the then outstanding securities of iPCS having the right to
            vote for the election of directors;

     (c)    the stockholders of iPCS approve a plan of complete liquidation of
            iPCS or an agreement for the sale or disposition by iPCS of all or
            substantially all of the assets of iPCS (or any transaction having a
            similar effect); or

     (d)    during any 24 month period, individuals who at the beginning of such
            period constitute the board of directors of iPCS, and any new
            director (other than a director designated by a Person who has
            entered into an agreement with iPCS to effect a transaction
            described in paragraph (a), (b) or (c) of this subsection 11.2)
            whose election by the board or nomination for election by the
            stockholders of iPCS was approved by a vote of at least two-thirds
            of the directors then still in office who either were directors at
            the beginning of the period or whose election or nomination for
            election was previously so approved, cease for any reason to
            constitute at least a majority thereof.

Notwithstanding the foregoing, an initial public offering of Stock shall not
constitute a Change in Control for purposes of the Plan.

                                     -12-

     12.  Amendment and Termination.
          -------------------------

     The Board may, at any time, amend or terminate the Plan or any Award,
provided that, subject to subsection 4.4 (relating to certain adjustments to
shares), no amendment or termination may materially adversely affect the rights
of any Participant or beneficiary under any Award made under the Plan prior to
the date such amendment is adopted by the Board.  Notwithstanding the foregoing
or any other provision of the Plan or any Award agreement, the Board or the
Committee may amend the Plan or the terms of any Award to the extent it deems
necessary to preserve pooling-of-interest accounting treatment for any
transaction which is intended to be accounted for through such accounting
method.
