of any other Lender to make any Advance required to be made by such other
Lender).

         (c)      Subject to Section 2.11, each Borrowing shall be comprised
entirely of Prime Advances or LIBOR Advances as the Company may request pursuant
to subsection 2.1(a). Each Lender may at its option make any LIBOR Advance by
causing any domestic or foreign branch of such Lender to make such Advance;
provided that any exercise of such option shall not affect the obligation of the
Company to repay such Advance in accordance with the terms of this Agreement.
Borrowings of more than one Type may be outstanding at the same time; provided
that the Company shall not be entitled to request any Borrowing which, if made,
would result in more than ten LIBOR Borrowings outstanding hereunder at any
time. For purposes of the foregoing, Borrowings having different Interest
Periods, regardless of whether they commence on the same date, shall be
considered separate Borrowings.



                                      -24-
   32

         (d)      Each Lender shall make each Advance to be made by it hereunder
on the Drawdown Date thereof by wire transfer of immediately available funds to
such account in Chicago as the Administrative Agent may designate not later than
12:00 p.m., Chicago time, and the Administrative Agent shall, promptly upon
receipt thereof, credit the amounts so received to an account as designated by
the Company, in the applicable Request for Financing, or, if a Borrowing shall
not occur on such date because any condition precedent herein specified shall
not have been met, return the amounts so received to the respective Lenders.

         (e)      Unless the Administrative Agent shall have received notice
from a Lender prior to the date of any Borrowing that such Lender will not make
available to the Administrative Agent such Lender's portion of such Borrowing,
the Administrative Agent may assume that such Lender has made such portion
available to the Administrative Agent on the date of such Borrowing in
accordance with subsection 2.2(d) above and the Administrative Agent may, in
reliance upon such assumption make available to the Company on such date a
corresponding amount. If the Administrative Agent shall have so made funds
available then, to the extent that such Lender shall not have made such portion
available to the Administrative Agent, such Lender and the Company severally
agree to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to the Company until the date such amount is
repaid to the Administrative Agent at (i) in the case of the Company, the
interest rate(s) applicable at the time to the Advances comprising such
Borrowing and (ii) in the case of such Lender, a rate determined by the
Administrative Agent to represent its cost of overnight or short-term funds
(which determination shall be conclusive absent manifest error). If such Lender
shall repay to the Administrative Agent such corresponding amount, such amount
shall constitute such Lender's Advance as part of such Borrowing for purposes of
this Agreement. If the Company shall repay to the Administrative Agent such
corresponding amount, such amount shall be deemed not to have been borrowed
hereunder for purposes of utilization of the Maximum Commitment.

         (f)      Notwithstanding any other provision of this Agreement, the
Company shall not be entitled to request any Interest Period with respect to any
LIBOR Borrowing that would end after the Maturity Date.

SECTION 2.3 EVIDENCE OF DEBT

         (a)      Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing the indebtedness of the Company to
such Lender resulting from each Advance made by such Lender from time to time,
including the amounts of principal and interest payable and paid such Lender
from time to time under this Agreement.

         (b)      The Administrative Agent shall maintain accounts in which it
will record (i) the amount of each Advance made hereunder, the Type thereof and
the Interest Period applicable thereto, (ii) the amount of any principal or
interest due and payable or to become due and payable from the Company to each
Lender hereunder and (iii) the



                                      -25-
   33

amount of any sum received by the Administrative Agent hereunder from the
Company and each Lender's share thereof.

         (c)      The entries made in the accounts maintained pursuant to
subsections 2.3(a) and 2.3(b) above shall be prima facie evidence of the
existence and amounts of the obligations therein recorded; provided, however,
that the failure of any Lender or the Administrative Agent to maintain such
accounts or any error therein shall not in any manner affect the obligations of
the Company to repay the Advances in accordance with their terms.

         (d)      Any Lender may request that Advances made by it be evidenced
by a promissory note. In such event, the Company shall execute and deliver to
such Lender a promissory note payable to the order of such Lender (or, if
requested by such Lender, to such Lender and its registered assigns)
substantially in the form of Exhibit A hereto (each a "Financing Note").

SECTION 2.4 REPAYMENT OF PRINCIPAL OF ADVANCES.

         (a)      The Company shall pay to the Administrative Agent on the
Maturity Date the principal of the Advances made by the Lenders outstanding at
the close of business on the Commitment Termination Date.

         (b)      The Advances shall be repaid as and when necessary to cause
the aggregate principal amount of the Advances outstanding not to exceed the
Available Commitment.

SECTION 2.5 PREPAYMENTS.

         (a)      Optional Prepayment; Voluntary Reduction of Commitment.

                  (i)      The Company may prepay Advances, in whole or in part,
         in integral multiples of $500,000 upon not less than three Business
         Days prior written notice to the Administrative Agent of the principal
         amount to be prepaid and the date of such prepayment. On the date
         specified for prepayment, the Company shall pay such principal amount
         plus accrued interest on such principal amount prepaid to the date of
         such prepayment. Notwithstanding the foregoing, unless the conditions
         set forth in subsection 2.5(b) hereof shall be simultaneously
         satisfied, LIBOR Advances may be only repaid on the last day of the
         Interest Period for such LIBOR Advance.

                  (ii)     The Company shall have the right, at any time and
         from time to time, without premium or penalty, to permanently reduce
         the Maximum Commitment hereunder by an amount of not less than $500,000
         or integral multiples thereof (or such lesser or greater amount
         representing the entirety of the remaining Available Commitment);
         provided, that any such reduction in the Maximum Commitment shall
         reduce the respective Commitment of each Lender pro rata; and, provided
         further, that no such reduction shall reduce the Maximum Commitment to
         an amount less than the sum of the then outstanding Advances.



                                      -26-
   34

         The right of the Company to voluntarily reduce the Maximum Commitment
         shall be exercisable by delivery of written notice (including by
         facsimile) or telephonic notice (thereafter promptly confirmed in
         writing) to the Administrative Agent prior to 12:00 p.m., Chicago time,
         at least three Business Days prior to the proposed permanent reduction
         in the Maximum Commitment, which notice shall specify the amount by
         which the Company proposes to permanently reduce the Maximum Commitment
         and the proposed date of such reduction.

         (b)      Broken Funding Indemnification.

                  The Company shall pay to the Agents and each Lender, such
amount or amounts as shall compensate the Agents and each Lender for any loss,
cost or expense incurred by an Agent or a Lender (as reasonably determined and
documented by affected Agent or Lender) as a result of:

                  (i)      prepayment or repayment of a LIBOR Advance on a date
         other than the last day of the Interest Period for such LIBOR Advance;
         or

                  (ii)     any failure by the Company to borrow a LIBOR Advance
         on the Drawdown Date specified in the relevant Request for Financing
         under Section 2.2 hereof, such compensation to include, without
         limitation, an amount equal to: (y) any actual loss or expense suffered
         by either Agent or any Lender during the period from such failure to
         borrow to the last day of such Interest Period if the rate of interest
         obtainable by such Lender or Agent upon the redeployment of an amount
         of funds equal to the amount not borrowed is less than the rate of
         interest applicable to such LIBOR Advance for such Interest Period
         (excluding any margin) or (z) any loss or expense suffered by the any
         Agent or any Lender in liquidating deposits in respect of LIBOR
         Advances prior to maturity.

                  The Company shall pay any amount due hereunder no later than
seven days after receipt of an invoice therefor from the affected Agent or
Lender.

         (c)      Effect of Prepayment.

                  All Advances prepaid (other than pursuant to Section 2.2(e)),
whether by mandatory or optional prepayment, may not be reborrowed. All
prepayments shall be applied to the principal balance of then outstanding
Advances.

SECTION 2.6 INTEREST; FEES.

         (a)      The Company shall pay to the Administrative Agent for the
ratable benefit of the Lenders interest on the outstanding principal amount of
each Advance made by the Lenders, for the period commencing on the date of such
Advance until such Advance is paid in full, at the following rate per annum:

                  (i)      if such Advance is a Prime Advance, a rate per annum
         equal to the Prime Rate (as in effect from time to time) plus the
         Applicable Margin; and



                                      -27-
   35

                  (ii)     if such Advance is a LIBOR Advance, for each Interest
         Period relating thereto, the LIBOR Rate for such Advance plus the
         Applicable Margin.


         Accrued interest on each Advance shall be paid in arrears on the
Interest Payment Dates. Notwithstanding the foregoing, interest that is payable
at the Post-Default Rate shall be payable from time to time on demand of the
Administrative Agent or the Required Lenders.

         (b)      Anything herein to the contrary notwithstanding, if, on or
prior to the determination of an interest rate for any LIBOR Advance for any
Interest Period therefor, any Lender reasonably determines (which determination
shall be conclusive absent manifest error):

                  (i)      by reason of any event affecting the money markets in
         the United States of America or the London interbank market, quotations
         of interest rates for the relevant deposits are not being provided in
         the relevant amounts or for the relevant maturities for purposes of
         determining the rate of interest for such LIBOR Advances under this
         Agreement; or

                  (ii)     the rates of interest referred to in the definition
         of "LIBOR Base Rate" in Section 1.1 hereof upon the basis of which the
         rate of interest on any LIBOR Advance for such period is determined, do
         not accurately reflect the cost to such Lender of making or maintaining
         such LIBOR Advance for such period, then, in addition to the Lender's
         rights under Sections 2.11 and 3.2,


such Lender shall give the Company and the Administrative prompt notice thereof
(and shall thereafter give the Company prompt notice of the cessation, if any,
of such condition), and so long as such condition remains in effect, such Lender
shall be under no obligation to make LIBOR Advances or to convert Prime Advances
into LIBOR Advances pursuant to subsection 2.2(a) or Section 2.8 hereof and the
Company shall, on the last day(s) of the then current Interest Period(s) for the
outstanding LIBOR Advances either prepay such LIBOR Advances in accordance with
subsection 2.5(a) hereof or convert such LIBOR Advances into Prime Advances.

         (c)      Without prejudice to the provisions of Section 10.2 hereof, in
the event of default by the Company in payment of any principal amount of the
Advances or interest thereon when due (whether at the stated maturity, by
acceleration or otherwise), the Company shall pay to the Lenders interest on
such past due and unpaid principal amount and (to the extent permitted by
applicable law) on such defaulted interest from the due date until the date of
payment in full (both before as well as after judgment), at the Post-Default
Rate. Each determination of any loss or expense by a Lender or an Agent under
this subsection 2.6(c) shall be conclusive in the absence of manifest error.

         (d)      Interest on all Prime Advances shall be computed on the basis
of a year of 365/366 days and actual days elapsed (including the first day but
excluding the last) occurring in the period for which payable and interest on
all LIBOR Advances shall be



                                      -28-
   36

computed on the basis of 360 days and actual days elapsed (including the first
day but excluding the last) occurring in the period for which payable.

         (e)      The Company agrees to pay quarterly in arrears to the
Administrative Agent on behalf of the Lenders on each March 31, June 30,
September 30, and December 31, commencing with December 31, 1999 through and
including December 31, 2001, and, if earlier, on the date the Obligations are
paid in full, a commitment fee equal to 0.50% per annum of the average daily
unused amount of the Commitments. The commitment fees required hereunder shall
be computed on the basis of the actual number of days elapsed in a year of 360
days.

SECTION 2.7 PAYMENTS

         (a)      Except as otherwise provided herein, all payments whatsoever
by the Company to the Administrative Agent hereunder or in respect of any
Financing Note shall be made in Dollars in same-day funds to the order of the
Motorola Credit Corporation at BankOne, Chicago, Illinois, USA, ABA#
071-000-013, for the account of the Administrative Agent, Account #5201748 (or
such other place as the Administrative Agent shall have designated in writing to
the Company at least five Business Days prior to the scheduled payment date),
not later than 2:00 p.m. Chicago time, on the day on which such payment shall
become due. Any amounts received after such time on any date shall be deemed to
have been received on the next succeeding Business Day for purposes of
calculating interest thereon.

         (b)      If any payment hereunder or in respect of any Financing Note
would otherwise be due on a day that is not a Business Day, such payment shall
be made on the next succeeding day that is a Business Day and including the
additional days elapsed in the computation of the interest payable on such next
succeeding Business Day.

SECTION 2.8 CONVERSION AND CONTINUATION.

         The Company shall have the right at any time upon prior irrevocable
notice to the Administrative Agent (a) not later than 12:00 p.m., Chicago time,
one Business Day prior to conversion, to convert any LIBOR Advance into a Prime
Advance, (b) not later than 11:00 a.m., Chicago time, three Business Days prior
to conversion or continuation, to convert any Prime Advance into a LIBOR Advance
or to continue any LIBOR Advance as a LIBOR Advance for an additional Interest
Period, and (c) not later than 11:00 a.m., Chicago time, three Business Days
prior to conversion, to convert the Interest Period with respect to any LIBOR
Advance to another permissible Interest Period, subject in each case to the
following:

                  (i)      each conversion shall be effected by each of the
         Lenders by recording for the account of such Lender the continued
         Advance of such Lender resulting from such conversion and reducing the
         Advance being converted by an equivalent principal amount; accrued
         interest on any Advance (or portion thereof) being converted shall be
         paid by the Company at the time of conversion;



                                      -29-
   37

                  (ii)     if any LIBOR Advance is converted at a time other
         than the end of the Interest Period applicable thereto, the Company
         shall pay, upon demand, any amounts due to the Lenders pursuant to
         subsection 2.5(b);

                  (iii)    any portion of an Advance maturing or required to be
         repaid in less one month may not be converted or continued as a LIBOR
         Advance with an Interest Period ending after the date such repayment is
         required; and

                  (iv)     upon notice to the Company from the Administrative
         Agent, after the occurrence and during the continuance of a Default or
         Event of Default, (A) no outstanding Advance may be converted into, or
         continued as, a LIBOR Advance, and (B) unless repaid, each LIBOR
         Advance shall be converted to a Prime Advance at the end of the
         Interest Period applicable thereto.

         Each notice pursuant to this Section 2.8 shall be irrevocable and shall
refer to this Agreement and specify (i) the identity and amount of the Advance
that the Company requests be converted or continued, (ii) whether such Advance
is to be converted to or continued as a LIBOR Advance or a Prime Advance, (iii)
if such notice requests a conversion, the date of such conversion (which shall
be a Business Day) and (iv) if such Advance is to be converted to or continued
as a LIBOR Advance, the Interest Period with respect thereto. If no Interest
Period is specified in any such notice with respect to any conversion to or
continuation as a LIBOR Advance, the Company shall be deemed to have selected an
Interest Period of one month's duration. If the Company shall not have given
notice in accordance with this Section 2.8 to continue any Advance into a
subsequent Interest Period (and shall not otherwise have given notice in
accordance with this Section 2.8 to convert such Advance), such Advance shall,
at the end of the Interest Period applicable thereto (unless repaid pursuant to
the terms hereof), automatically be continued into a new Interest Period as a
Prime Advance.

SECTION 2.9 USE OF PROCEEDS.

         The Company agrees to use the proceeds of the Advances for the purpose
of supporting the Company's build-out or operation of its network and employing
primarily the products and services of Motorola Entities.

SECTION 2.10 CHANGE IN LAW.

         If any change in any applicable Governmental Rule has made (or has made
it apparent that it is) unlawful for the Company to perform any of its
obligations under any of the Credit Documents and such change could reasonably
be expected to have a Material Adverse Effect then (a) the Lenders shall be
discharged from all obligations to make, renew or maintain the Advances, and (b)
the Company shall on demand pay to the Administrative Agent for the benefit of
the Lenders, without premium or penalty except as provided in subsection 2.5(b),
the outstanding principal amount of the Advances together with accrued interest
thereon and all other moneys due to the Lenders hereunder; provided, that for so
long as the Company is diligently pursuing the contest of the same by
appropriate proceedings and such contest could not reasonably be expected to
have a Material Adverse Effect and adequate reserves have been established in
accordance with GAAP, then the Lenders shall not be so discharged and the
Company shall not be required to so pay upon demand.



                                      -30-
   38

SECTION 2.11 ILLEGALITY.

         (a)      Notwithstanding any other provision of this Agreement, if,
after the date hereof, any change in any Governmental Rule shall make it
unlawful for any Lender to make or maintain any LIBOR Advance or to give effect
to its obligations as contemplated hereby with respect to any LIBOR Advance,
then, by written notice to the Company and to the Administrative Agent:

                  (i)      such Lender may declare that LIBOR Advances will not
         thereafter (for the duration of such unlawfulness) be made by such
         Lender hereunder (or be continued for additional Interest Periods and
         Prime Advances will not thereafter (for such duration) be converted
         into LIBOR Advances), whereupon any request for a LIBOR Borrowing (or
         to convert a Prime Rate Borrowing to a LIBOR Borrowing or to continue a
         LIBOR Borrowing for an additional Interest Period) shall, as to such
         Lender only, be deemed a request for a Prime Advance (or a request to
         continue a Prime Advance as such for an additional Interest Period or
         to convert a LIBOR Advance into a Prime Advance), unless such
         declaration shall be subsequently withdrawn; and

                  (ii)     such Lender may require that all outstanding LIBOR
         Advances made by it be converted to Prime Advances in which event all
         such LIBOR Advances shall be automatically converted to Prime Advances
         as of the effective date of such notice as provided in subsection
         2.11(b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal that would otherwise have been applied to
repay the LIBOR Advances that would have been made by such Lender or the
converted LIBOR Advances of such Lender shall instead be applied to repay the
Prime Advances made by such Lender in lieu of, or resulting from the conversion
of, such LIBOR Advances.

         (b)      For purposes of this Section 2.11, a notice to the Company by
any Lender shall be effective as to each LIBOR Advance made by such Lender, if
lawful, on the last day of the Interest Period(s) currently applicable to LIBOR
Advances of such Lender; in all other cases such notice shall be effective on
the date of receipt by the Company.

SECTION 2.12 PRO RATA TREATMENT.

         Except as required under Sections 2.7 and 2.11, each Borrowing, each
payment or prepayment of principal of any Borrowing, each payment of interest on
the Advances, each payment of the fees required under the Fee Letter or under
Section 2.6, each reduction of the Commitments and each conversion of any
Borrowing to or continuation of any Borrowing as a Borrowing of any Type shall
be allocated pro rata among the Lenders in accordance with their respective
applicable Commitments (or, if such Commitments shall have expired or been
terminated, in accordance with the respective principal amounts of their
outstanding Advances). Each Lender agrees that in computing such Lender's
portion of any Borrowing to be made



                                      -31-
   39

hereunder, the Administrative Agent may, in its discretion, round each Lender's
percentage of such Borrowing to the next higher or lower whole Dollar amount.

SECTION 2.13 SHARING OF SETOFFS.

         Each Lender agrees that if it shall, through the exercise of a right of
banker's lien, setoff or counterclaim against the Company or any other Credit
Party, or pursuant to a secured claim under Section 506 of Title 11 of the
United States Code or other security or interest arising from, or in lieu of,
such secured claim, received by such Lender under any applicable bankruptcy,
insolvency or other similar law or otherwise, or by any other means, obtain
payment (voluntary or involuntary) in respect of any Advance or Advances as a
result of which the unpaid principal portion of its Advances shall be
proportionately less than the unpaid principal portion of the Advances of any
other Lender, it shall be deemed simultaneously to have purchased from such
other Lender at face value, and shall promptly pay to such other Lender the
purchase price for, a participation in the Advances of such other Lender, so
that the aggregate unpaid principal amount of the Advances and participation in
Advances held by each Lender shall be in the same proportion to the aggregate
unpaid principal amount of all Advances then outstanding as the principal amount
of its Advances prior to such exercise of banker's lien, setoff or counterclaim
or other event was to the principal amount of all Advances outstanding prior to
such exercise of banker's lien, setoff or counterclaim or other event; provided,
however, that if any such purchase or purchases or adjustments shall be made
pursuant to this Section 2.13 and the payment giving rise thereto shall
thereafter be recovered, such purchase or purchases or adjustments shall be
rescinded to the extent of such recovery and the purchase price or prices or
adjustment restored without interest. The Company expressly consents to the
foregoing arrangements and agrees that any Lender holding a participation in an
Advance deemed to have been so purchased may exercise any and all rights of
banker's lien, setoff or counterclaim with respect to any and all moneys owing
by the Company to such Lender by reason thereof as fully as if such Lender had
made an Advance directly to the Company in the amount of such participation.

                     SECTION 3 FUNDING AND YIELD PROTECTION

SECTION 3.1 TAXES, DUTIES, FEES AND CHARGES.

         (a)      Any and all payments by or on behalf of the Company hereunder
and under any other Credit Document shall be made, in accordance with Section
2.7, free and clear of and without deduction for any and all current or future
Taxes. If the Company shall be required to deduct any Taxes from or in respect
of any sum payable hereunder or under any other Credit Document to any Agent or
any Lender (or any Transferee), (i) the sum payable shall be increased by the
amount (an "additional amount") necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 3.1) such Agent or such Lender (or Transferee), as the case may be,
shall receive an amount equal to the sum it would have received had no such
deductions been made, (ii) the Company shall make such deductions and (iii) the
Company shall pay the full amount deducted to the relevant Governmental
Authority in accordance with applicable law.



                                      -32-
   40

         (b)      In addition, the Company agrees to pay to the relevant
Governmental Authority in accordance with applicable law any current or future
stamp, documentary, excise, transfer, sales, property or similar taxes, charges
or levies (including, without limitation, mortgage recording taxes and similar
fees) that arise from any payment made hereunder or under any other Credit
Document or from the execution, delivery, enforcement or registration of, or
otherwise with respect to, this Agreement or any other Credit Document imposed
by any Governmental Authority in the United States or the jurisdiction of any
Payment Location ("Other Taxes").

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

         (d)      As soon as practicable after the date of any payment of Taxes
or Other Taxes by the Company to the relevant Governmental Authority, the
Company will deliver to the Administrative Agent, at its address referred to in
Section 12.7, the original or a certified copy of a receipt issued by such
Governmental Authority evidencing payment thereof.

         (e)      Each Lender (or Transferee) that is organized under the laws
of a jurisdiction other than the United States, any State thereof or the
District of Columbia (a "Non-U.S. Lender") that is entitled to an exemption from
or reduction of, withholding tax under the law of the jurisdiction in which the
Company is located, or any treaty to which such jurisdiction is a party, with
respect to payments by the Company under this Agreement and the other Credit
Documents shall deliver to the Company (with a copy to the Administrative
Agent), at the time or times prescribed by applicable law, such properly
completed and executed documentation prescribed by applicable law or reasonably
requested by the Company as will permit such payments to be made without
withholding or at a reduced rate. In addition, each Non-U.S. Lender shall
deliver such documentation promptly upon the obsolescence or invalidity of any
documentation previously delivered by such Non-U.S. Lender. Notwithstanding any
other provision of this subsection 3.1(e), a Non-U.S. Lender shall not be
required to deliver any documentation pursuant to this subsection 3.1(e) that
such Non-U.S. Lender is not legally able to deliver.

         (f)      The Company shall not be required to indemnify any Non-U.S.
Lender or to pay any additional amounts to any Non-U.S. Lender, in respect of
United States Federal withholding tax pursuant to subsection 3.1(a) or (c) above
to the extent that (i) the obligation to withhold amounts with respect to United
States Federal withholding tax



                                      -33-
   41

existed and would apply to payments made to such Non-U.S. Lender on the date
such Non-U.S. Lender became a party to this Agreement (or, in the case of a
Transferee that is a participation holder, on the date such participation holder
became a Transferee hereunder) or, with respect to payments to a new Lending
Office, the date such Non-U.S. Lender designated such new Lending Office with
respect to an Advance; provided, however, that this subsection 3.1(f) shall not
apply (x) to any Transferee or new Lending Office that becomes a Transferee or
new Lending Office as a result of an assignment, participation, transfer or
designation made at the request of the Company and (y) to the extent the
indemnity payment or additional amounts any Transferee, or any Lender (or
Transferee), acting through a new Lending Office, would be entitled to receive
(without regard to this subsection 3.1(f)) do not exceed the indemnity payment
or additional amounts that the person making the assignment, participation or
transfer to such Transferee, or Lender (or Transferee) making the designation of
such new Lending Office, would have been entitled to receive in the absence of
such assignment, participation, transfer or designation or (ii) the obligation
to pay such additional amounts would not have arisen but for a failure by such
Non-U.S. Lender to comply with the provisions of subsection 3.1(e) above.

         (g)      Nothing contained in this Section 3.1 shall require any Lender
(or any Transferee) or the Administrative Agent or the Collateral Agent to make
available any of its tax returns (or any other information that it deems to be
confidential or proprietary).

SECTION 3.2 CHANGE IN CIRCUMSTANCES.

         (a)      In the event that there shall hereafter occur any change in
any Governmental Rule which increases or will increase (i) the cost to any Agent
or any Lender of maintaining any reserves or special deposits against the LIBOR
Advances or (ii) any other cost of any Agent or any Lender of complying with any
law, regulation or condition with respect to the LIBOR Advances, and the result
of any of the foregoing is or will be to increase the cost to any Agent or any
Lender (each such affected party being referred to as an "Affected Party") of
making or maintaining such Affected Party's LIBOR Advances or to reduce the
amount of any payment (whether of principal, interest or otherwise) receivable
by the Affected Party hereunder, then upon receipt of a request from the
Affected Party, the Company shall pay or reimburse to the Affected Party, such
amount as will compensate the Affected Party for such additional cost or
reduction of payment; provided that the Company shall only be liable for such
costs applicable to LIBOR Advances then outstanding. Amounts payable hereunder
shall be due three (3) days after invoice therefor.

         (b)      The protection of subsection 3.2(a) hereof shall apply to
voluntary compliance by the Agents and the Lenders with restraints, guidelines
or policies not having the force of law and shall apply if any Agent or any
Lender shall comply with any law, regulation or condition irrespective of any
possible contention of invalidity or non-applicability thereof.

         (c)      The Affected Party will promptly (but in no event later than
forty-five (45) days after actual knowledge of the occurrence of the event
described in subsection 3.2(a) hereof) inform the Company and the Administrative
Agent by facsimile of its intention to



                                      -34-
   42

claim indemnification under this Section 3.2. The facsimile statement of the
Affected Party as to the amount sufficient to indemnify the Affected Party
against any increased cost, reduction or payment incurred, suffered or made by
the Affected Party supported by the computations made by the Affected Party in
arriving at such figure, shall, in the absence of manifest error, be conclusive
as to the amount thereof and binding on Company.

         A claim made under this Section 3.2 may be made before or after the end
of the Interest Period to which such claim relates and before or after any
repayment of all or part of the Advance to which such Interest Period relates.
An increased cost shall be an increased cost for the purpose of subsection
3.2(a) hereof even if the payment or quantification of such increased cost is
not or cannot be made until after the expiry of any Interest Period to which it
relates.

         (d)      In the event of any such change or request as is contemplated
by subsection 3.2(a) hereof, the Affected Party will use reasonable efforts to
mitigate the effect or likely effect of such change or request by transferring
its LIBOR Advances to another jurisdiction or otherwise; provided that the
Affected Party shall be under no obligation to transfer the LIBOR Advances to
another jurisdiction or to take any other action to mitigate the effect or
likely effect of such change or request if, in the reasonable opinion of the
Affected Party, such transfer or other action could reasonably be expected to
have an adverse effect upon the Affected Party, whether as a result of taxes,
credit policies, political considerations or otherwise; provided further, that
the Company shall reimburse the Affected Party on demand for all expenses
(including, without limitation, attorney's fees) incurred by the Affected Party
in effecting such transfer and the Affected Party shall have no obligation to
effect any such transfer unless the Affected Party is satisfied that it will not
suffer any adverse consequences as a result of such transfer for which it has
not been indemnified by the Company. If any Affected Party is entitled to
reimbursement under this subsection 3.2(d) for any cost, the Affected Party
shall deliver to the Company a statement of the nature and amount of such cost
which statement shall constitute prima facie evidence as to the amount due to
the Affected Party under this subsection 3.2(d).

         (e)      If the Company elects (which election shall be irrevocable) by
giving at least two Business Days prior written notice to the Affected Party,
the Company may, without penalty or premium, prepay to any Affected Party any of
such Affected Party's Advances outstanding Advances on any Interest Payment Date
applicable to such Advances with respect to which the Company has received a
claim under this Section 3.2 together with accrued interest thereon and all
other sums due to the Affected Party (including, without limitation, amounts
accrued or due under this Section 3.2).

         (f)      If any Lender requests compensation under this section 3.2, or
if the Company is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to this Section
3.2, or if any Lender defaults in its obligation to fund Advances hereunder,
then the Company may, at its sole expense and effort, upon Notice to such Lender
and the Agents, require such Lender to assign and delegate, without recourse (in
accordance with and subject to the restrictions contained in Section 12.5), all
of its interests, rights and obligations under this Agreement



                                      -35-
   43

to an assignee that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment); provided that (i) the Company
shall have received the prior written consent of the Administrative Agent if
such assignee is not a Lender at the time of assignment, which consent shall not
be unreasonably withheld or delayed, (ii) such Lender shall have received
payment of an amount equal to the outstanding principal of its Advances, accrued
interest thereon, accrued fees and all other amounts payable to it hereunder,
from the assignee (to the extent of such outstanding principal and accrued
interest and fees) or the Company (in the case of all other amounts), and (iii)
in the case of any such assignment resulting from a claim for compensation under
this Section 3.2 or payments required to be made under Section 3.1, such
assignment will result in a reduction in such compensation or payments. A Lender
shall not be required to make any such assignment or delegation if, prior
thereto, as a result of a waiver by such Lender or otherwise, the circumstances
entitling the Company to require such assignment or delegation cease to apply.

                   SECTION 4 EXPENSES; INDEMNIFICATION; FEES

SECTION 4.1 EXPENSES.

        The Company agrees to pay, whether or not any Advance is made hereunder,

of the Credit Documents (including, without limitation, all costs and expenses

and not solely requested by the Lenders; (e) all costs and expenses (including,
without limitation, legal fees and disbursements of counsel) incident to the
enforcement, protection or preservation of any right or claim of the Lenders or
the Agents under any of the Credit Documents; and (f) all transfer, stamp,

the Credit Documents; provided the Company's aggregate obligations with respect
to clauses (a), (b) and (c) above (and to the extent incurred prior to the
Initial Funding Date, clause (f) above) shall not exceed $50,000. Fees shall be
deemed reasonable to the extent they are reviewed and approved by the
Administrative Agent.

SECTION 4.2 INDEMNIFICATION.

         (a)      Without in any way limiting the applicability of subsection
4.2(b) hereof, and without regard to whether the Company or any other Person has
disclosed any fact to



                                      -36-
   44

the Agents or the Lenders, the Company hereby indemnifies and holds harmless the
Agents, the Lenders and each of their respective officers, directors, employees,
consultants, advisors and agents (collectively, the "Indemnitees") from and
against any and all actions, suits, claims, damages, demands, judgments, losses,
liabilities, costs or expenses whatsoever, including, without limitation,
reasonable attorneys' fees, which any Indemnitee may sustain or incur (or which
may be claimed against the Indemnitee by any Person or entity whatsoever) to the
extent arising by reason of or in connection with the execution and delivery of
the Credit Documents, or payment or failure to pay the Obligations, or the
occurrence of an Event of Default or the pursuit by the Agents, the Lenders or
any one of them, of any legal remedy in connection with an Event of Default or
arising out of or in connection with the Agents' or the Lenders' entering into
this Agreement or the Security Documents, or enforcing their remedies hereunder
or thereunder; provided that, the Company shall not be required to indemnify an
Indemnitee for any actions, suits, claims, damages, demands, judgments, losses,
liabilities, costs or expenses to the extent, but only to the extent, caused by
the Indemnitee's willful misconduct or gross negligence. Fees shall be deemed
reasonable to the extent they are reviewed and approved by the Administrative
Agent.

         (b)      Notwithstanding anything in subsection 4.2(a) hereof to the
contrary, and without regard to whether the Company or any other Person has
disclosed any fact to an Indemnitee, the Company agrees to indemnify, defend and
hold the Indemnitees free and harmless from and against any and all actions,
suits, claims, demands, judgments, liabilities, losses, costs, damages and

to property or economic loss) in connection with any Materials of Environmental
Concern used, generated, treated, stored, recycled, disposed of, handled,
discharged or otherwise located or released in, on, under or from the Systems,
the Telecommunications Businesses, the Collateral or related property, except to
the extent resulting from such Indemnitee's grossly negligent act or willful
misconduct with respect to such Materials of Environmental Concern.

         In order to secure the due payment and performance by the Company of

                    SECTION 6 REPRESENTATIONS AND WARRANTIES

         The Company makes the representations and warranties attributed to it
as a Credit Party in this Section 6 and the Company makes, on behalf of each of
the other Credit Parties, the representations and warranties attributable to
such Credit Party in this Section 6.

SECTION 6.1 ORGANIZATION.

         (a)      Each Credit Party that is not a natural Person is duly
organized and validly existing under the laws of its state or jurisdiction of
organization. Schedule 6.1(a) hereto accurately and completely lists, as to the
Company and the Operating Affiliates (excluding the Subsidiaries of the Persons
explicitly referenced in the definition thereof): (i) the jurisdiction of
incorporation or organization of each such entity, and the type of legal entity
that each of them is, (ii) as to each such Person that is a corporation, the
classes and number of authorized and outstanding shares of capital stock of each
such corporation, and the owners of such outstanding shares of capital stock,
and (iii) as to each such Person that is a legal entity other than a corporation
(but not a natural Person), the type and amount of equity interests authorized
and outstanding of each such entity, and the owners of such equity interests.
All of the shares, quota shares or other equity interests of the Company and the
Operating Affiliates (excluding the Subsidiaries of the Persons explicitly
referenced in the definition thereof) that are issued and outstanding have been
duly and validly issued and are fully paid and non-assessable, and are owned by
the Persons referred to on Schedule 6.1(a) hereto, and, to the extent owned by
the Company or any Restricted Subsidiary, are owned free and clear of any Lien
except for Permitted Liens. Except as set forth on Schedule 6.1(a) hereto, there
are no outstanding warrants, options, contracts or commitments of any kind
entitling any Person to purchase or otherwise acquire any shares of capital
stock or other equity interests of any Credit Party, nor are there outstanding
any securities that are convertible into or exchangeable for any shares of
capital stock or other equity interests of such Credit Party. Except as set
forth on Schedule 6.1(a) hereto, no Credit Party (other than the Company) has
any Subsidiaries. The Company has no Subsidiaries other than those listed on
Schedule 6.1(a) hereof and after the Closing Date any additional Subsidiaries to
the extent permitted hereunder.

         (b)      Each Credit Party is in good standing (to the extent that such
jurisdiction recognizes the legal concept of good standing) in its state or
jurisdiction of organization



                                      -38-
   46

and in each state or jurisdiction in which it is qualified to do business. There
are no jurisdictions in which the character of the properties owned or proposed
to be owned by any Credit Party or in which the transaction of the business of
any Credit Party as now conducted or as proposed to be conducted requires or
will require such Credit Party to qualify to do business and as to which failure
so to qualify could reasonably be expected to have a Material Adverse Effect.

SECTION 6.2 POWER; AUTHORITY.

         (a)      Each Credit Party has full legal right, power and authority to
carry on its respective present business, to own its respective properties and
assets, to incur the obligations thereunder, to execute and deliver each Credit
Document to which it is a party, and, to the extent it is a party thereto, to
perform and observe the terms and conditions thereof.

         (b)      All appropriate and necessary corporate, partnership and legal
actions have been taken by the Company to authorize the execution, delivery and
performance of each Credit Document, and the Company is duly authorized to
execute and deliver and to perform its obligations under each of the Credit
Documents.

SECTION 6.3 GOVERNMENTAL APPROVALS.

         (a)      All Governmental Approvals under all applicable Governmental
Rules in connection with (i) the due execution, delivery and performance by the
Company of its obligations, and the exercise of its rights, under the Credit
Documents, and (ii) the grant by the Company of the assignments and security
interests granted by the Security Documents and the validity and enforceability
thereof and for the perfection of and the exercise by the Lender Parties of
their respective rights and remedies thereunder, have been duly obtained on or
before the Closing Date and are final, in full force and effect and all
administrative appeal periods with respect thereto have terminated. The Credit
Parties have obtained, and are in compliance in all material respects with, all
Governmental Approvals under all applicable Governmental Rules which are
necessary or required for the operation of the Systems and the conduct of the
Telecommunications Businesses, except for those Governmental Approvals the
failure to have or to be in compliance with could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. There is no
proceeding pending or (to the Credit Parties' knowledge after due inquiry)
threatened, that could reasonably be expected to rescind, terminate, modify or
suspend any Governmental Approval the termination, rescission, modification or
suspension of which could reasonably be expected to have a Material Adverse
Effect, and no such disclosed matter could reasonably be expected to have a
Material Adverse Effect. None of the Credit Parties, respectively, has any
knowledge that the information set forth in any application submitted by any
Credit Party in connection with any Governmental Approval (the termination,
rescission, modification or suspension of which could reasonably be expected to
have a Material Adverse Effect) is inaccurate or incomplete in any material
respect as of the date submitted and as of the Closing Date and true and
complete copies of such Governmental Approvals have been



                                      -39-
   47

(to the extent requested by the Administrative Agent) delivered to the
Administrative Agent.

SECTION 6.4 EXECUTION, ENFORCEABILITY, VIOLATION OF LAW AND AGREEMENTS.

         Each of the Credit Documents has been duly executed and delivered by
the Company and constitutes, the legal, valid and binding contract, agreement
and obligation of the Company enforceable in accordance with its terms except as
(x) the enforceability of the Credit Documents may be limited by bankruptcy,
insolvency or similar laws relating or affecting creditors' rights generally,
(y) the availability of equitable remedies, and (z) rights to indemnification
and contribution as they may be limited by public policy; provided, however,
that such exceptions shall not materially interfere with the practical
realization of the benefits of the Security Documents or the Liens created
thereby, except for: (i) possible delay, (ii) situations that may arise under
Chapter 11 of the Bankruptcy Code and comparable statutes of Canada, and (iii)
equitable orders of the Bankruptcy Court and comparable courts in Canada. The
execution, delivery and performance of the terms of each of the Credit Documents
by the Company and the payment by the Company of all amounts due on the dates
and in the currency provided for therein (a) will not, except as is set forth on
Schedule 6.4 hereto, violate or contravene any Governmental Rule or other
provision of law or other governmental directive, whether or not having the
force of law, which is applicable to the Company, which violation or
contravention thereof individually or in the aggregate could reasonably be
expected to have a Material Adverse Effect; (b) will not, except as is set forth
on Schedule 6.4 hereto, contravene any governmental guideline or policy
statement applicable to the Company but not having the force of law, which
contravention thereof individually or in the aggregate could reasonably be
expected to have a Material Adverse Effect; (c) will not conflict with, violate
or breach the Articles of Incorporation or By-laws (or any other organizational
documents), as the case may be, of the Company; (d) will not conflict with or
result in the breach of any provision of, or result in the creation or
imposition of any Lien or other preferential arrangement under, any other
indenture, agreement, mortgage, contract or other undertaking, or instrument to
which the Company is a party or by which it or any of its properties or assets
is bound other than the Credit Documents; and (e) will not constitute a default
or an event that, with the giving of notice or the passing of time, or both,
would constitute a default under any such agreement or instrument. To the extent
the representations and warranties contained in this Section 6.4 relate to any
law, Governmental Rule, governmental directive or other matter related to an
"employee benefit plan", within the meaning of Section 3(3) of ERISA, or a
"plan", within the meaning of Section 4975(e)(1) of the Code, such
representations and warranties are made assuming the truth of the
representation, warranty and covenant contained in the last sentence of
subsection 2.1(a).

SECTION 6.5 FINANCIAL STATEMENTS; BUSINESS PLAN.

         (a)      The consolidated audited balance sheets of the Company and its
Subsidiaries and consolidated statements of operations, changes in stockholders'
equity and cash flows of the Company and its Subsidiaries each as of December
31, 1998, and all other information and data heretofore furnished by the
Company, or any agent of the Company on behalf of the Company to the
Administrative Agent, including, the quarterly consolidated balance sheets and
consolidated statements of operations, changes in stockholders' equity and cash
flows (each as at March 31, 1999), have been prepared in



                                      -40-
   48

accordance with GAAP and fairly present the condition and results of operations
of the Company and its Subsidiaries as of such dates or for such periods. Except
for those matters (i) set forth in the Company's SEC Reports filed on or prior
to the Closing Date or (ii) as set forth on Schedule 6.5, since December 31,
1998, no event that could reasonably be expected to have a Material Adverse
Effect has occurred. None of the Company or any of its Subsidiaries has
contingent obligations, liabilities for taxes or other outstanding financial
obligations which are material either individually or in the aggregate.

         (b)      The financial and business projections contained in the
Approved Business Plan submitted to the Administrative Agent were prepared in
good faith and based upon assumptions believed to be reasonable by the Company
(as of the date of the Approved Business Plan). The Approved Business Plan has
been accompanied by a summary of the key assumptions utilized in preparing the
Approved Business Plans.

SECTION 6.6 TAXES.

         Each Credit Party has timely paid all required taxes, duties, fees and
assessments of any kind with respect to, or in connection with, its respective
income, business, properties and certificates of stock and each is current with
all the tax returns required to be filed by it except such taxes, if any, as are
being contested in good faith and by proper proceedings and as to which either
(x) adequate reserves have been established in accordance with GAAP on the books
of such Credit Party or (y) the aggregate amount of such taxes, duties, fees and
assessments is less than $5,000,000 and the non-payment of which would not
reasonably be expected to have a Material Adverse Effect under such
circumstances. There are no tax liens against any of the Credit Parties or any
of their respective properties. No Credit Party is party to any action or
proceeding by any Governmental Authority for the assessment or collection of
taxes, nor has any claim for assessment or collection of taxes been asserted
against any of the Credit Parties or any of their respective properties.

SECTION 6.7 PROPERTIES.

         All property and assets (including, without limitation, leasehold and
other non-fee simple property interests) owned by each Credit Party, including,
without limitation, contracts, Governmental Approvals currently held by such
Credit Party, entitlements and other rights, titles or interest of such Credit
Party relating or incidental to the Systems or the Telecommunications Businesses
are owned by it free and clear of all Liens other than Permitted Liens.

SECTION 6.8 COMPLIANCE WITH LAWS.

         (a)      Each Credit Party complies and has complied in all material
respects with all applicable Governmental Rules, except to the extent such
non-compliance could not, individually or in the aggregate, be reasonably
expected to have a Material Adverse Effect. To the extent the representations
and warranties contained in the preceding sentence relate to any Governmental
Rule related to an "employee benefit plan", within the meaning, of Section 3(3)
of ERISA, or a "plan", within the meaning of Section 4975(e)(1) of the Code,
such representations and warranties are made assuming the truth



                                      -41-
   49

of the representation, warranty and covenant contained in the last sentence of
subsection 2.1(a). Except as previously disclosed to the Administrative Agent
and the Lenders in writing or disclosed in the Company's SEC Reports, no Credit
Party has received any communication of which the Company has not made the
Administrative Agent and the Lenders aware in writing promptly after the Company
becoming aware thereof, from a Governmental Authority that alleges that any
Credit Party is not in full compliance in all material respects with all
applicable Governmental Rules, and to the Credit Parties' knowledge, after due
inquiry, there are no circumstances that may prevent or interfere with such full
compliance in all material respects in the future.

         (b)      Each Credit Party is in compliance with all applicable laws
relating to the employment of labor, wages, hours and conditions of work,
collective bargaining, withholding tax and the payment of social security
contributions and other labor-related taxes, except to the extent any
non-compliances cannot, individually or in the aggregate, be reasonably expected
to have a Material Adverse Effect. No Credit Party is liable for any arrears in
wages, compensation, benefits, premiums, taxes or penalties for failure to
comply with any of the foregoing laws except to the extent that the same are
being contested in good faith and by proper proceedings and as to which either
(y) adequate reserves have been established in accordance with GAAP on the books
of such Credit Party or (z) nonpayment of which could not have a Material
Adverse Effect under such circumstances and could not result in an aggregate
liability in excess of $5,000,000. To the extent the representations and
warranties contained in this Section 6.8(b) relate to any law related to an
"employee benefit plan", within the meaning of Section 3(3) of ERISA, or a
"plan", within the meaning of Section 4975(e)(1) of the Code, such
representations and warranties are made assuring the truth of the
representation, warranty and covenant contained in the last sentence of
subsection 2.1(a).

         (c)      The operations of each Credit Party comply in all material
aspects with all applicable Environmental Laws.

         (d)      There are no claims, investigations, litigation,
administrative proceedings, whether pending or, to the knowledge of the Company,
threatened, or judgments or orders, relating to any Materials of Environmental
Concern or alleging, the violation of any Environmental Laws (collectively
"Environmental Matters") relating IN any way to any property or to the
operations of such Credit Party.

         (e)      No Materials of Environmental Concern are presently stored or
otherwise located on, in or under real estate owned or leased by any Credit
Party except in compliance in all material respects with all Environmental Laws,
and, no part of such real estate or adjacent parcels of real estate, including,
without limitation, the groundwater located thereon, is to the knowledge of the

or otherwise) in respect of any Plan has occurred, except for any such
Reportable Event as could not reasonably be expected to have a Material Adverse
Effect. No Credit Party has received any notice from the PBGC that any Plan is

been or is expected to be incurred by any Credit Party (other than for payment
of PBGC premiums in the ordinary course) with respect to any Plan. To the
knowledge of the Credit Parties, respectively, after due inquiry, no event has
occurred and there exists no condition or set of circumstances, that presents a
material risk of the termination or partial termination of any Plan that could
reasonably be expected to result in a material liability on the part of any
Credit Party to the PBGC with respect to any Plan.

         (d)      No non-exempt "prohibited transaction" as defined in Section

by each Credit Party, or with respect to which such Credit Party is liable,
under the Plans, determined using the actuarial methods and assumptions used by
the relevant Plan's actuary as of the last valuation date for which an actuarial
valuation was completed to determine such Plan's funded status, did not as of
the last valuation date as of which an actuarial valuation has been completed,
which in the case of any individual Plan was not earlier than January 1, 1998,
exceed the actuarial value of the assets of the Plans allocable to such vested
and non-vested benefits by a material amount.

         (g)      No Credit Party is a participating employer in: (i) any Plan
under which more than one unrelated employer makes contributions as described in
Section 4063 and 4064 of ERISA, or (ii) a multiemployer plan as defined in
Section 4001 (a)(3) of ERISA.

         (d)      Notwithstanding anything to the contrary contained herein or
in the other Credit Documents:

                  (i)      If as of the last Business Day of each calendar month
         the Aggregate Pledge Collateral Value is greater than 130% of the
         Maximum Collateralized Amount, then all cash collateral then on deposit
         and subject to the Cash Collateral Agreement shall be released at the
         written direction of the Company. If as of the last Business Day of
         each calendar month the Aggregate Collateral Value is less than 125% of
         the Maximum Collateralized Amount, then, within five Business Days of
         such date, the Company shall deposit into the account subject to the
         Cash Collateral Agreement such amount of cash necessary, if any, so
         that, after giving effect thereto, the Aggregate Collateral Value
         (determined as of the date of such deposit and using the Closing Price
         rather than the Average Closing Price for such determination) is at
         least 125% of the Maximum Collateralized Amount. Along with the
         deliveries made pursuant to Sections 7.2 and 7.3 hereof, the Company
         shall deliver a certificate to the Administrative Agent setting forth
         (with calculations) the Aggregate Collateral Value and the Aggregate
         Pledge Collateral Value as of the last Business Day of each calendar
         month during the applicable period.

                  (ii)     The Collateral Agent may require the deposit of
         additional cash by the Company to be subject to the Cash Collateral
         Agreement if the Aggregate Collateral Value at any time, including as
         of the last Business Day of a calendar month, is less than 125% of the
         Maximum Collateralized Amount by giving written notice thereof to the
         Company. Such deposit shall be made within 5 days of the giving of such
         notice and shall be in an amount sufficient to make the Aggregate
         Collateral Value (as of the date of such deposit) at least 125% of the
         Maximum Collateralized Amount.

                  (iii)    Provided that the Company has not elected to deposit
         cash as cash collateral subject to the Cash Collateral Agreement in the
         amount and as provided in Section 5.1(a)(ii), the Company may request
         (which request shall be in writing and delivered to the Agents) that
         the cash on deposit and subject to the Cash Collateral Agreement be
         released per the written direction of the Company if, at any time, the
         Aggregate Pledge Collateral Value is greater than 130% of the Maximum
         Collateralized Amount. Such cash shall be released upon the written
         direction of the Company to the extent that, after giving effect to the
         release, the Aggregate Collateral Value (including any cash collateral
         not released) is at least 125% of the Maximum Collateralized Amount
         (determined as of the date of the release).

SECTION 7.13 CONSTRUCTION OF THE SYSTEMS.

         The Company shall proceed, together with the Operating Affiliates,
diligently to construct the Systems in the Relevant Countries as required and
permitted (to the extent necessary to achieve the Approved Business Plan)

conditions of the its Governmental Approvals, preserve and maintain each such

SECTION 8.16 RESTRICTED SUBSIDIARIES.

Restricted Subsidiary to, sell, convey, transfer or otherwise dispose of any
assets, other than in the ordinary course of business, to any Unrestricted
Subsidiary or any Person that becomes an Unrestricted Subsidiary as part of such
transaction, unless such Subsidiary does not own any stock of, and does not own
or hold any Lien on any property of, the Company or any Restricted Subsidiary;
provided, that (a) any guarantee by the Company or any Restricted Subsidiary of
the Company of any Indebtedness of the Subsidiary being designated as an
Unrestricted Subsidiary shall be deemed an incurrence of such Indebtedness or an
Investment by the Company or such Restricted Subsidiary (or both, if
applicable); (b) either (i) the Subsidiary to be deemed an Unrestricted
Subsidiary has total gross assets of $1,000 or less, or (ii) if the Subsidiary
to be deemed an Unrestricted Subsidiary has total gross assets greater than
$1,000, then such designation shall, for all purposes of Section 8.6 (including
clause (b) thereof), be deemed to be a Restricted Payment of an amount equal to
the fair market value of the Company's ownership interest in such Subsidiary
(including, without



                                      -61-

(c) if applicable, the incurrence of Indebtedness and the Investment referred to
in clause (a) of this proviso would be permitted under Sections 8.1 and 8.6,
respectively.

         The Company's Board of Directors (the "Board") may designate any
existing Unrestricted Subsidiary or any Person that is about to become a
Subsidiary of the Company as a Restricted Subsidiary if, after giving effect to
such action (and, if such designation is made in connection with the acquisition
of a Person or an operating business that is about to become a Subsidiary of the
Company, after giving effect to all terms of such acquisition) (a) on a pro
forma basis, on the date of such action, the Liens and Indebtedness, if any, of
such Unrestricted Subsidiary or Person outstanding immediately prior to such
designation would have been permitted to be incurred (and shall be deemed to
have been incurred) for all purposes of this Agreement; and (b) no Default or
Event of Default shall have occurred and be continuing.

         Notwithstanding the foregoing provisions of this Section 8.16, the
Board may not designate any of the Operating Affiliates to be an Unrestricted
Subsidiary.

         The Board, from time to time, may designate any Person that is about to
become a Subsidiary of the Company as an Unrestricted Subsidiary, and may
designate any newly-created Subsidiary as an Unrestricted Subsidiary, if at the
time such Subsidiary is created it contains no assets (other than such de
minimis amount of assets then required by law for the formation of corporations)
and no Indebtedness.

         Subsidiaries of the Company that are not designated by the Board as
Restricted or Unrestricted Subsidiaries shall be deemed to be Restricted
Subsidiaries. Notwithstanding any provisions of this Section 8.16, all
Subsidiaries of an Unrestricted Subsidiary shall be Unrestricted Subsidiaries.

         (e)      The Lender Parties may (but shall not be obligated to) make

   76

of the obligations owing to the Lender Parties hereunder and shall be repayable

                  SECOND - To the payment of the unpaid principal of and
interest on any Advance which shall have become due and payable and other fees,

other remedies hereunder or with respect to any Collateral.

SECTION 10.3 CUMULATIVE RIGHTS.

         No failure or delay on the part of any Lender Party in exercising any
right, power or remedy accruing to it upon any breach or default of the Company
under any of the Credit Documents shall impair any such right, power or remedy
nor shall it be construed as a waiver of any such breach or default thereafter
occurring, nor shall a waiver of any single breach or default be deemed a waiver
of any other breach or default theretofore or thereafter occurring, nor shall
any single or partial exercise of any such right or power preclude any other or
further exercise thereof or the exercise of any other right or power hereunder.
To the fullest extent permitted by law, all remedies, either under the Credit
Documents or by law otherwise afforded the Lender Parties shall be cumulative
and not alternative.

SECTION 10.4 WAIVER OF DEMAND; SETOFF.

THE COMPANY ALSO WAIVES THE BENEFIT OF ALL RIGHTS OF SETOFF AND ALL VALUATION,
APPRAISAL AND EXEMPTION LAWS TO THE EXTENT PERMITTED BY LAW.

SECTION 10.5 WAIVER OF NOTICE.

         IN THE EVENT OF AN EVENT OF DEFAULT, THE COMPANY HEREBY WAIVES TO THE
EXTENT PERMITTED BY LAW ALL RIGHTS TO NOTICE AND HEARING OF ANY KIND PRIOR TO
THE EXERCISE BY THE CREDITOR OF ITS RIGHTS TO REPOSSESS ANY COLLATERAL WITHOUT
JUDICIAL PROCESS OR TO REPLEVY, ATTACH OR LEVY UPON ANY COLLATERAL WITHOUT PRIOR
NOTICE OR HEARING. THE COMPANY ACKNOWLEDGES THAT IT HAS BEEN ADVISED BY COUNSEL
OF ITS CHOICE WITH RESPECT TO THIS TRANSACTION AND THIS AGREEMENT.

          SECTION 11 THE ADMINISTRATIVE AGENT AND THE COLLATERAL AGENT

         In order to expedite the transactions contemplated by this Agreement,
Motorola Credit Corporation is hereby appointed to act as Administrative Agent
and Collateral Agent on behalf of the Lenders (for purposes of this Section 11,
the Administrative Agent and the Collateral Agent are referred to collectively
as the "Agents"). Each of the Lenders and each assignee of any such Lender,
hereby irrevocably authorizes the Agents to take such actions on behalf of such
Lender or assignee and to exercise such powers as are specifically delegated to
the Agents by the terms and provisions hereof and of the other Credit Documents,
together with such actions and powers as are reasonably incidental thereto. The
Administrative Agent is hereby expressly authorized by the Lenders, without
hereby limiting any implied authority, (a) to receive on behalf of the Lenders
all payment of principal of and interest on the Advances and all other amounts
due to the Lenders hereunder, and promptly to distribute to each Lender its
proper share of each payment so received; (b) to give notice on behalf of each
of the Lenders to the Company of any Event of Default specified in this
Agreement of which the Administrative Agent has actual knowledge acquired in
connection with its agency hereunder; and (c) to distribute to each Lender
copies of all notices, financial statements and other materials delivered by the
Company or any other Credit Party pursuant to this Agreement or the other Credit
Documents as received by the Administrative Agent. Without limiting the
generality of the foregoing, the Agents are hereby expressly authorized to
execute any and all documents (including releases) with respect to the
Collateral and the rights of the parties secured thereby with respect thereto,
as contemplated by and in accordance with the provisions of this Agreement and
the Security Documents.

         Neither the Agents nor any of their respective directors, officers,
employees or agents shall be liable as such for any action taken or omitted by
any of them except for its or his own gross negligence or willful misconduct, or
be responsible for any statement, warranty or representation herein or the
contents of any document delivered in connection herewith, or be required to
ascertain or to make any inquiry concerning the performance or observance by the
Company or any other Credit Party of any of the terms, conditions, covenants or
agreements contained in any Credit Document. The Agents shall not be responsible
to the Lenders for the



                                      -70-
   78

due execution, genuineness, validity, enforceability or effectiveness of this
Agreement or any other Credit Documents, instruments or agreements. The Agents
shall in all cases be fully protected in acting, or refraining from acting, in
accordance with written instructions signed by the Required Lenders and, except
as otherwise specifically provided herein, such instructions and any action or
inaction pursuant thereto shall be binding on all the Lenders. Each Agent shall,
in the absence of knowledge to the contrary, be entitled to rely on any
instrument or document believed by it in good faith to be genuine and correct
and to have been signed or sent by the proper person or persons. Neither the
Agents nor any of their respective directors, officers, employees or agents
shall have any responsibility to the Company or any other Credit Party on
account of the failure of or delay in performance or breach by any Lender of any
of its obligations hereunder or to any Lender on account of the failure of or
delay in performance or breach by any other Lender or the Company or any other
Credit Party of any of their respective obligations hereunder or under any other
Credit Document or in connection herewith or therewith. Each of the Agents may
execute any and all duties hereunder by or through agents or employees and shall
be entitled to rely upon the advice of legal counsel selected by it with respect
to all matters arising hereunder and shall not be liable for any action taken or
suffered in good faith by it in accordance with the advice of such counsel.

         The Lenders hereby acknowledge that neither Agent shall be under any
duty to take any discretionary action permitted to be taken by it pursuant to
the provisions of this Agreement unless it shall be requested in writing to do
so by the Required Lenders.

         Subject to the appointment and acceptance of a successor Agent as
provided below, either Agent may resign at any time by notifying the Lenders and
Company. Upon any such resignation, the Required Lenders shall have the right to
appoint a successor. If no successor shall have been so appointed by the
Required Lenders and shall have accepted such appointment within 30 days after
the retiring Agent gives notice of its resignation, then the retiring Agent may,
on behalf of the Lenders, appoint a successor Agent which shall be a bank with
an office in New York, New York, having a combined capital and surplus of at
least $500,000,000 or an Affiliate of any such bank. Upon acceptance of any
appointment as Agent hereunder by a successor bank, such successor shall succeed
to and become vested with all the rights, powers, privileges and duties of the
retiring Agent and the retiring Agent shall be discharged from its duties and
obligations hereunder. After the Agent's resignation hereunder, the provisions
of this Article and Section 8.5 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting as
Agent.

         With respect to the Advances made by it hereunder, each Agent in its
individual capacity and not as Agent shall have the same rights and powers as
any other Lender and may exercise the same as though it were not an Agent, and
the Agents and their Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with the Company or any Subsidiary or
other Affiliate thereof as if it were not an Agent.

         Each Lender agrees (a) to reimburse the Agents, on demand, in the
amount of its pro rata share (based on its aggregate Commitment hereunder) of
any expenses incurred for the benefit of the Lenders by the Agents, including
counsel fees and compensation of agents and employees paid for services rendered
on behalf of the Lenders, that shall not have been reimbursed by the



                                      -71-
   79

Company and (b) to indemnify and hold harmless each Agent and any of its
directors, officers, employees or agents, on demand, in the amount of such pro
rata share, from and against any and all liabilities, taxes, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever that may be imposed on, incurred
by or asserted against it in its capacity as Agent or any of them in any way
relating to or arising out of this Agreement or any other Credit Document or any
action taken or omitted by it or any of them under this Agreement or any other
Credit Document, to the extent the same shall not have been reimbursed by the
Company or any other Credit Party; provided that no Lender shall be liable to an
Agent or any such other indemnified person for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements are determined by a court of competent jurisdiction by
final and nonappealable judgment to have resulted from the gross negligence or
willful misconduct of such Agent or any of its directors, officers, employees or
agents.

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

         The Collateral Agent shall be deemed to have exercised reasonable care
in the custody and preservation of any of the Collateral in its possession if it
takes such action for that purpose as the Company requests in writing, but
failure of the Collateral Agent to comply with any such request shall not of
itself be deemed a failure to exercise reasonable care, and no failure of the
Collateral Agent to preserve or protect any rights with respect to such
Collateral against prior parties, or to do any act with respect to the
preservation of such Collateral not so requested by the Company, shall be deemed
a failure to exercise reasonable care in the custody or preservation of such
Collateral.

                            SECTION 12 MISCELLANEOUS

SECTION 12.1 WAIVER OF SOVEREIGN IMMUNITY.

         To the extent that the Company or any of its respective assets has or
hereafter may acquire any right to immunity from suit, setoff, legal proceedings
generally, attachment prior to judgment, attachment in aid of execution or other
attachment or execution of judgment on the rounds of sovereignty or otherwise,
the Company hereby irrevocably waives such rights to immunity for itself and its
assets in respect of its obligations arising under or relating to any of the
Credit Documents or any related documentation.

SECTION 12.2 VENUE FOR SUIT.

         The Company and the Lender Parties each irrevocably hereby expressly
waives all right to object to jurisdiction or execution in any legal action or
proceeding relating to this Agreement, the Financing Note or any other Credit
Document which it may now or hereafter have by reason of its domicile or by
reason of any subsequent or other domicile and hereby irrevocably consents that
any legal action, suit or proceeding arising out of or relating to any of the
Credit Documents and any other document or instrument required to be executed in
relation thereto may be instituted in the federal courts of the United States
District Court of the Southern District of New York and the courts of the State
of New York, and by execution and delivery of this Agreement, the Company and
the Lender Parties submits to and accepts and consents with regard to any such
action or proceeding for itself and in respect of its properties and assets,
generally and unconditionally, the jurisdiction of any such court. The Company
hereby waives any objection it may now or hereafter have to the laying of the
venue of any such action, suit or proceeding, and further waives any claim that
any such action, suit or proceeding brought in any of the aforesaid courts has
been brought in any inconvenient forum.

         The Company hereby irrevocably designates, appoints and empowers CT
Corporation System with offices at 1633 Broadway, New York, New York, 10019, and
successors as the designee, appointee and agent of the Company to receive,
accept and acknowledge, for and on behalf of the Company and its properties,
service of any and all legal process, summons, notices and documents which may
be served in such action, suit or proceeding relating to the Financing Note or
this Agreement or any other Credit Document in the case of the courts of the
United States District Court of the Southern District of New York or of the
courts of the State of Illinois, which service may be made on any such designee,
appointee and agent in accordance with legal prescribed for such courts. The
Company agrees to take any and all action necessary to continue such designation
in full force and effect and should such designee, appointee and agent become
unavailable for this purpose for any reason, the Company will forthwith
irrevocably designate a new designee, appointee and agent with offices in New
York, New York, which shall irrevocably agree to act as such, with the powers
and for purposes specified in this Section 12.2. The Company further irrevocably
consents and agrees to service of any and all legal process, summons, notices
and documents out of any of the aforesaid courts in any such action, suit or
proceeding relating to the Financing Note or this Agreement or any other Credit
Document delivered to the Company in accordance with this Section 12.2 or to its
then designee, appointee or agent for service. If service is made upon such
designee, appointee and agent, a copy of such process, summons, notice or
document shall also be provided to the Company by registered or certified mail,
or overnight express air courier, provided that failure to provide such copy to
the Company shall not impair or affect in any way the validity of such service
or any judgement rendered in such action or proceedings. The Company agrees that
service upon the Company or any such designee, appointee and agent as provided
for herein shall constitute valid and effective personal service upon the
Company with respect to matters contemplated in this Section 12.2 and that the
failure of any such designee, appointee and agent to give any notice of such
service to the Company shall not impair or affect in any way the validity of
such service or any judgment rendered in any action or proceeding based thereon.
Nothing herein shall limit or be construed to limit the rights of the Lender
Parties to commence proceedings against the Company in any other venue where
assets of the Company may be found.

this Agreement (including all or a portion of the Commitment and the Advances at
the time owing to it) without the consent of the Company (the "Syndication").
The Initial Lender may request the Company to assist in the Syndication as
contemplated by this Section.

         (c)      In addition to and without limiting the foregoing, each Lender
may, without the consent of the Company, sell participations to one or more
banks or other entities (a "Participant") in all or a portion of the Lender's

   82

limitation, providing information to and responding to questions from

Credit Document or consent to any departure by the Company therefrom shall in
any event be effective unless the same shall be permitted by paragraph

only in the specific instance and for the purpose for which given. No notice or
demand on the Company in any case shall entitle the Company to any other or
further notice or demand in similar or other circumstances.

this Section, the definition of the term "Required Lenders", increase the total
Commitments or release any Guarantor or all or any substantial part of the
