applied ratably to prepay the remaining Term Loan A Principal
Debt and Term Loan B Principal Debt, and reduce the Revolver
Commitment as provided in SECTIONS 2.7(b) through 2.7(f);
PROVIDED FURTHER, that upon prepayment in full of Term Loan C
Principal Debt owing to Term Loan C Lenders other than Declining
C Lenders the remainder of any prepayment amount that is to be
applied to Term Loan C Principal Debt shall be applied ratably
to prepay Term Loan C Principal Debt owing to Declining C
Lenders. Any Term Loan C Lender may elect not to accept its
ratable share of a partial prepayment by giving written notice
to the Administrative Agent not later than 11:00 a.m. Dallas,
Texas time on the Business Day immediately preceding the
scheduled prepayment date.

(g) MANDATORY PREPAYMENTS OF INTEREST/CONSEQUENTIAL LOSS.
All prepayments under this SECTION 2.7 shall be made, together with
accrued interest to the date of such prepayment on the principal amount
prepaid, together with any Consequential Loss arising as a result
thereof.

(h) APPLICATION OF REVOLVER COMMITMENT REDUCTION. All
Revolver Commitment reductions hereunder shall be applied ratably to
each Revolver Lender's Committed Sum under the Revolver Facility and
shall be applied to the regularly scheduled Revolver Commitment
reductions under SECTION 3.2(c) in inverse order of maturities; PROVIDED
THAT, (i) if there is no Default or Potential Default, no mandatory
commitment reduction under SECTION 2.7(b) (including any amount of
reduction from a prepayment under SECTION 2.7(b) that is applied to the
Revolver Commitment as a result of the opt-out provisions in
SECTION 2.7(f)) shall reduce the Revolver Commitment to an amount equal
to the lesser of $10,000,000 or the Revolver Commitment then outstanding
except in the event of the repayment in full of the Obligation; (ii) if
any Revolver Commitment reductions

30
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

are not made as a result of CLAUSE (i) preceding, then the amount of
such mandatory prepayment not applied as a Revolver Commitment reduction
shall be applied to the Term Loan A Principal Debt until paid in full,
then to the Term Loan B Principal Debt until paid in full, and then to
the Term Loan C Principal Debt until paid in full; and (iii) if required
pursuant to SECTION 2.7(e) Borrower shall also make a mandatory
prepayment of the Revolver Principal Debt, TOGETHER WITH (x) all
accrued and unpaid interest on the principal amount so prepaid and (y)
any Consequential Loss arising as a result thereof.

(i) APPLICATION OF MANDATORY PREPAYMENTS OF TERM PRINCIPAL
DEBT. All mandatory prepayments of the term Principal Debt under any
Term Facility shall be applied ratably to each Term Lender's Committed
Sum under such Term Facility and shall be applied to the
regularly-scheduled Term Principal Debt reductions for such Term
Facility as set forth in SECTION 3.2(d), (e), or (f) (as the case
may be) in inverse order of maturities.

2.8 BORROWING PROCEDURE. The following procedures apply to all
Borrowings (other than a Swing Line Borrowing):

(a) Each Borrowing shall be made on Borrower's notice (a
"NOTICE OF BORROWING," substantially in the form of EXHIBIT B-1) to
Administrative Agent requesting that Lenders fund a Borrowing on a
certain date (the "BORROWING DATE"), which notice (i) shall be
irrevocable and binding on Borrower, (ii) shall specify if it is for a
Borrowing under the Revolver Facility, Term Loan A, Term Loan B, or Term
Loan C, (iii) shall specify the Borrowing Date, amount, Type, and (for a
Borrowing comprised of Eurodollar Rate Borrowings) Interest Period, and
(iv) must be received by Administrative Agent no later than 10:00 a.m.
Dallas, Texas time on the third Business Day preceding the Borrowing
Date for any Eurodollar Rate Borrowing or on the Business Day
immediately preceding the Borrowing Date for any Base Rate Borrowing.
Administrative Agent shall timely notify each Lender with respect to
each Notice of Borrowing.

(b) Each Lender shall remit its Pro Rata Part for the
relevant Facility of each requested Borrowing to Administrative Agent's
principal office in Dallas, in funds which are or will be available for
immediate use by Administrative Agent by 1:00 p.m. Dallas time on the
Borrowing Date therefor. Subject to receipt of such funds,
Administrative Agent shall (unless to its actual knowledge any of the
conditions precedent therefor have not been satisfied by Borrower or
waived by Required Lenders) make such funds available to Borrower by
causing such funds to be deposited to Borrower's account as designated
to Administrative Agent by Borrower. Notwithstanding the foregoing,
unless Administrative Agent shall have been notified by a Lender prior
to a Borrowing Date that such Lender does not intend to make available
to Administrative Agent such Lender's Pro Rata Part of the applicable
Borrowing, Administrative Agent may assume that such Lender has made
such proceeds available to Administrative Agent on such date, as
required herein, and Administrative Agent may (unless to its actual
knowledge any of the conditions precedent therefor have not been
satisfied by Borrower or waived by Required Lenders), in reliance upon
such assumption (but shall not be required to), make available to
Borrower a corresponding amount in accordance with the foregoing terms,
but, if such corresponding amount is not in fact made available to
Administrative Agent by such Lender on such Borrowing Date,
Administrative Agent shall be entitled to recover such corresponding
amount on demand (i) from such Lender, together with interest at the
Federal Funds Rate during the period commencing on the date such
corresponding amount was made available to Borrower and ending on (but
excluding) the date Administrative Agent recovers such corresponding
amount from such

31
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

Lender, or (ii) if such Lender fails to pay such corresponding amount
forthwith upon such demand, then from Borrower, TOGETHER WITH interest
at a rate per annum equal to the applicable rate for such Borrowing
during the period commencing on such Borrowing Date and ending on
(but excluding) the date Administrative Agent recovers such
corresponding amount from Borrower. No Lender shall be responsible
for the failure of any other Lender to make its Pro Rata Part of any
Borrowing.

SECTION 3 TERMS OF PAYMENT.

3.1 LOAN ACCOUNTS, NOTES, AND PAYMENTS.

(a) The Revolver Principal Debt (other than Swing Line

hereunder on the same day Administrative Agent shall have received the
same from Borrower; PROVIDED such payment or prepayment is received by
Administrative Agent prior to 12:00 noon Dallas, Texas time, and
otherwise before 12:00 noon Dallas time on the Business Day next
following. If and to the extent Administrative Agent shall not make

▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

(g) On any date of determination if the Revolver Commitment
Usage exceeds the Revolver Commitment or the Swing Line Principal Debt
exceeds the Swing Line Commitment then in effect, then Borrower shall
make a mandatory prepayment of the Principal Debt under the Revolver
Facility or the Swing Line Subfacility, respectively, in at least the
amount of such excess, TOGETHER WITH (x) all accrued and unpaid interest
on the principal amount so prepaid and (y) any Consequential Loss
arising as a result thereof. All mandatory prepayments hereunder shall
be applied Pro Rata to each Revolver Lender's Committed Sum and shall be
applied to the regularly-scheduled Commitment reductions hereunder in
inverse order of maturity.

3.3 INTEREST OPTIONS. Except where specifically otherwise
provided, Borrowings shall bear interest at a rate per annum equal to the
LESSER OF (a) as to the respective Type of Borrowing (as designated by
Borrower in accordance with this Agreement), the Base Rate plus the
Applicable Margin for Base Rate Borrowings or the Adjusted Eurodollar Rate
plus the Applicable Margin for Eurodollar Rate Borrowings, AND (b) the
Maximum Rate. Each change in the Base Rate or the Maximum Rate, subject to
the terms of this Agreement, will become effective, without notice to
Borrower or any other Person, upon the effective date of such change.

3.4 QUOTATION OF RATES. It is hereby acknowledged that a
Responsible Officer or other appropriately designated officer of Borrower may
call Administrative Agent on or before the date on which a Notice of
Borrowing is to be delivered by Borrower in order to receive an indication of
the rates then in effect, but such indicated rates shall neither be binding
upon Administrative Agent or Lenders nor affect the rate of interest which
thereafter is actually in effect when the Notice of Borrowing is given.

3.5 DEFAULT RATE. At the option of Required Lenders and to the
extent permitted by Law, all past-due Principal Debt and accrued interest
thereon shall bear interest from maturity (stated or by acceleration) at the
Default Rate until paid, regardless whether such payment is made before or
after entry of a judgment.

3.6 INTEREST RECAPTURE. If the designated rate applicable to any
Borrowing exceeds the Maximum Rate, the rate of interest on such Borrowing
shall be limited to the Maximum Rate, but any subsequent reductions in such
designated rate shall not reduce the rate of interest thereon below the
Maximum Rate until the total amount of interest accrued thereon equals the
amount of interest which would have accrued thereon if such designated rate
had at all times been in effect. In the event that at maturity (stated or by
acceleration), or at final payment of the Principal Debt, the total amount of
interest paid or accrued is less than the amount of interest which would have
accrued if such designated rates had at all times been in effect, then, at
such time and to the extent permitted by Law, Borrower shall pay an amount
equal to the difference between (a) the LESSER OF the amount of interest
which would have accrued if such designated rates had at all times been in
effect AND the amount of interest which would have accrued if the Maximum
Rate had at all times been in effect, and (b) the amount of interest actually
paid or accrued on the Principal Debt.

3.7 INTEREST CALCULATIONS.

(a) All payments of interest shall be calculated on the
basis of actual number of days (including the first day but excluding
the last day) elapsed but computed as if each calendar year consisted of
360 days in the case of a Eurodollar Rate Borrowing (unless such
calculation would result in the interest on the Borrowings exceeding the
Maximum Rate, in which event such interest shall be calculated on the
basis of a year of 365 or 366 days, as the case may be), and 365 or

36
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

366 days, as the case may be, in the case of a Base Rate Borrowing.
All interest rate determinations and calculations by Administrative
Agent shall be conclusive and binding absent manifest error.

(b) The provisions of this Agreement relating to the
calculation of the Base Rate and the Adjusted Eurodollar Rate are
included only for the purpose of determining the rate of interest or
other amounts to be paid hereunder that are based upon such rate.

3.8 MAXIMUM RATE. Regardless of any provision contained in any
Loan Paper, neither Administrative Agent nor any Lender shall ever be
entitled to contract for, charge, take, reserve, receive, or apply, as
interest on the Obligation, or any part thereof, any amount in excess of the
Maximum Rate, and, if Lenders ever do so, then such excess shall be deemed a
partial prepayment of principal and treated hereunder as such and any
remaining excess shall be refunded to Borrower. In determining if the
interest paid or payable exceeds the Maximum Rate, Borrower and Lenders
shall, to the maximum extent permitted under applicable Law, (a) treat all
Borrowings as but a single extension of credit (and Lenders and Borrower
agree that such is the case and that provision herein for multiple Borrowings
is for convenience only), (b) characterize any nonprincipal payment as an
expense, fee, or premium rather than as interest, (c) exclude voluntary
prepayments and the effects thereof, and (d) amortize, prorate, allocate, and
spread the total amount of interest throughout the entire contemplated term
of the Obligation; PROVIDED THAT, if the Obligation 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 Amount, Lenders shall refund such excess, and, in such event, Lenders
shall not, to the extent permitted by Law, be subject to any penalties
provided by any Laws for contracting for, charging, taking, reserving, or
receiving interest in excess of the Maximum Amount.

3.9 INTEREST PERIODS. When Borrower requests any Eurodollar Rate
Borrowing, Borrower may elect the interest period (each an "INTEREST PERIOD")
applicable thereto, which shall be, at Borrower's option, one, two, three, or
six months (or other periods, if requested by Borrower and available from the
Lenders); PROVIDED, HOWEVER, that: (a) the initial Interest Period for a
Eurodollar Rate Borrowing shall commence on the date of such Borrowing
(including the date of any conversion thereto), and each Interest Period
occurring thereafter in respect of such Borrowing shall commence on the day
on which the next preceding Interest Period applicable thereto expires; (b)
if any Interest Period for a Eurodollar Rate Borrowing begins on a day for
which there is no numerically corresponding Business Day in the calendar
month at the end of such Interest Period, such Interest Period shall end on
the next Business Day immediately following what otherwise would have been
such numerically corresponding day in the calendar month at the end of such
Interest Period (UNLESS such date would be in a different calendar month from
what would have been the month at the end of such Interest Period, or UNLESS
there is no numerically corresponding day in the calendar month at the end of
the Interest Period; whereupon, such Interest Period shall end on the last
Business Day in the calendar month at the end of such Interest Period); (c)
no Interest Period may be chosen with respect to any portion of the Principal
Debt which would extend beyond the scheduled repayment date (including any
dates on which mandatory prepayments are required to be made) for such
portion of the Principal Debt; and (d) no more than an aggregate of eight (8)
Interest Periods shall be in effect at one time.

3.10 CONVERSIONS. For Borrowings under the Revolver Facility,
Term Loan A, or Term Loan B, Borrower may (a) convert a Eurodollar Rate
Borrowing on the last day of an Interest Period to a Base Rate Borrowing, (b)
convert a Base Rate Borrowing at any time to a Eurodollar Rate Borrowing, and
(c) elect a new Interest Period (in the case of a Eurodollar Rate Borrowing),
by giving notice (a "NOTICE OF CONVERSION," substantially in the form of
EXHIBIT B-2) of such intent no later than 10:00 a.m. Dallas,

37
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

Texas time on the third Business Day prior to the date of conversion or the
last day of the Interest Period, as the case may be (in the case of a
conversion to a Eurodollar Rate Borrowing or an election of a new Interest
Period), and no later than 10:00 a.m. Dallas, Texas time one Business Day
prior to the last day of the Interest Period (in the case of a conversion to
a Base Rate Borrowing); PROVIDED THAT, the principal amount converted to, or
continued as, a Eurodollar Rate Borrowing shall be in an amount not less than
$5,000,000 or a greater integral multiple of $1,000,000. Administrative Agent
shall timely notify each Lender with respect to each Notice of Conversion.
Absent Borrower's Notice of Conversion or election of a new Interest Period,
a Eurodollar Rate Borrowing shall be deemed converted to a Base Rate
Borrowing effective as of the expiration of the Interest Period applicable
thereto. No Eurodollar Rate Borrowing may be either made or continued as a
Eurodollar Rate Borrowing, and no Base Rate Borrowing may be converted to a
Eurodollar Rate Borrowing, if the interest rate for such Eurodollar Rate
Borrowing would exceed the Maximum Rate. The right to convert from a Base
Rate Borrowing to a Eurodollar Rate Borrowing, or to continue as a Eurodollar
Rate Borrowing, shall not be available during the occurrence of a Default or
a Potential Default.

3.11 ORDER OF APPLICATION.

(a) Payments and prepayments of the Obligation shall be
applied in the order and manner specified in this Agreement; PROVIDED,
HOWEVER, if no order is otherwise specified and no Default or Potential
Default has occurred and is continuing, payments and prepayments of the
Obligation shall be applied first to fees, second to accrued interest
then due and payable on the Principal Debt, and then to the remaining
Obligation in the order and manner as Borrower may direct.

(b) If a Default or Potential Default has occurred and is
continuing (or if Borrower fails to give directions as permitted under
SECTION 3.11(a)), any payment or prepayment (including proceeds from the
exercise of any Rights) shall be applied to the Obligation in the
following order: (i) to the ratable payment of all fees, expenses, and
indemnities for which Agents or Lenders have not been paid or reimbursed
in accordance with the Loan Papers (as used in this SECTION 3.11(b)(i),
a "RATABLE PAYMENT" for any Lender or any Agent shall be, on any date of
determination, that proportion which the portion of the total fees,
expenses, and indemnities owed to such Lender or such Agent bears to the
total aggregate fees and indemnities owed to all Lenders and Agents on
such date of determination); (ii) to the ratable payment of accrued and
unpaid interest on the Revolver Principal Debt and the Term Principal
Debt (as used in this SECTION 3.11(b)(ii), "RATABLE PAYMENT" means, for
any Revolver Lender or Term Lender, on any date of determination, that
proportion which the accrued and unpaid interest on the Revolver
Principal Debt or the Term Principal Debt (as the case may be) owed to
such Revolver Lender or Term Lender bears to the total accrued and
unpaid interest under the Loan Papers owed to all Revolver Lenders and
all Term Lenders); (iii) to the ratable payment of the Revolver
Principal Debt and the Term Principal Debt (as used in this
SECTION 3.11(b)(iii), "RATABLE PAYMENT" means for any Revolver Lender or
any Term Lender, on any date of determination, that proportion which the
Revolver Principal Debt or the Term Principal Debt (as the case may be)
owed to such Revolver Lender or Term Lender bears to the sum of the
Principal Debt and the Term Principal Debt owed to all Revolver Lenders
and all Term Lenders; and (iv) to the payment of the remaining
Obligation in the order and manner Required Lenders deem appropriate.

Subject to the provisions of SECTION 12 and provided that Administrative Agent
shall not in any event be bound to inquire into or to determine the validity,
scope, or priority of any interest or entitlement of any

38
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

Revolver Lender or Term Lender and may suspend all payments or seek
appropriate relief (including, without limitation, instructions from Required
Lenders or an action in the nature of interpleader) in the event of any doubt
or dispute as to any apportionment or distribution contemplated hereby,
Administrative Agent shall promptly distribute such amounts to each Lender in
accordance with the Agreement and the related Loan Papers.

3.12 SHARING OF PAYMENTS, ETC. If any Lender shall obtain any
payment (whether voluntary, involuntary, or otherwise, including, without
limitation, as a result of exercising its Rights under SECTION 3.13) which is
in excess of its ratable share of any such payment (except as provided herein
with respect to the Term Facility opt-outs in SECTION 2.7(f)), such Lender
shall purchase from the other Revolver Lenders and the Term Lenders such
participations as shall be necessary to cause such purchasing Lender to share
the excess payment ratably with each of them; PROVIDED, HOWEVER, that if all
or any portion of such excess payment is thereafter recovered from such
purchasing Lender, the purchase shall be rescinded and the purchase price
restored to the extent of such recovery. Borrower agrees that any Lender so
purchasing a participation from another Revolver Lender or Term Lender
pursuant to this Section may, to the fullest extent permitted by Law,
exercise all of its Rights of payment (including the Right of offset) with
respect to such participation as fully as if such Revolver Lender or Term
Lender were the direct creditor of Borrower in the amount of such
participation.

3.13 OFFSET. Upon the occurrence and during the continuance of a
Default, each Lender shall be entitled to exercise (for the benefit of all
Revolver Lenders and Term Lenders in accordance with SECTION 3.12) the Rights
of offset and/or banker's Lien against each and every account and other
property, or any interest therein, which any Company may now or hereafter
have with, or which is now or hereafter in the possession of, such Lender to
the extent of the full amount of the Obligation.

3.14 BOOKING BORROWINGS. To the extent permitted by Law, any
Lender may make, carry, or transfer its Borrowings at, to, or for the account
of any of its branch offices or the office of any of its Affiliates; PROVIDED
THAT, no Affiliate shall be entitled to receive any greater payment under
SECTION 4 than the transferor Lender would have been entitled to receive with
respect to such Borrowings.

SECTION 4 CHANGE IN CIRCUMSTANCES.

4.1 INCREASED COST AND REDUCED RETURN.

(a) If, after the date hereof, the adoption of any
applicable Law or any change in any applicable Law or any change in the
interpretation or administration thereof by any Governmental Authority,
or compliance by any Lender (or its Applicable Lending Office) with any
request or directive (whether or not having the force of law) of any
such Governmental Authority:

(i) shall subject such Lender (or its Applicable
Lending Office) to any Tax or other charge with respect to any
Eurodollar Rate Borrowing, its Notes, or its obligation to loan
Eurodollar Rate Borrowings, or change the basis of taxation of
any amounts payable to such Lender (or its Applicable Lending
Office) under this Agreement or its Notes in respect of any
Eurodollar Rate Borrowings (other than taxes imposed on the
overall net income of such Lender by the jurisdiction in which
such Lender has its principal office or such Applicable Lending
Office);

(ii) shall impose, modify, or deem applicable any
reserve, special deposit, assessment, or similar requirement
(other than the Reserve Requirement utilized in the

39
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

determination of the Adjusted Eurodollar Rate) relating to any
extensions of credit or other assets of, or any deposits with or
other liabilities or commitments of, such Lender (or its
Applicable Lending Office), including the commitment of such
Lender hereunder; or

(iii) shall impose on such Lender (or its Applicable
Lending Office) or the London interbank market any other
condition affecting this Agreement or its Notes or any of such
extensions of credit or liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such
Lender (or its Applicable Lending Office) of making, converting into,
continuing, or maintaining any Eurodollar Rate Borrowings or to reduce
any sum received or receivable by such Lender (or its Applicable Lending
Office) under this Agreement or its Notes with respect to any Eurodollar
Rate Borrowing, then Borrower shall pay to such Lender on demand such
amount or amounts as will compensate such Lender for such increased cost
or reduction. If any Lender requests compensation by Borrower under
this SECTION 4.1(a), Borrower may, by notice to such Lender (with a copy
to Administrative Agent), suspend the obligation of such Lender to loan
or continue Borrowings of the Type with respect to which such
compensation is requested, or to convert Borrowings of any other Type
into Borrowings of such Type, until the event or condition giving rise
to such request ceases to be in effect (in which case the provisions of
SECTION 4.4 shall be applicable); PROVIDED, THAT such suspension shall
not affect the right of such Lender to receive the compensation so
requested.

(b) If, after the date hereof, any Lender shall have
determined that the adoption of any applicable Law regarding capital
adequacy or any change therein or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof, or any request or directive
regarding capital adequacy (whether or not having the force of law) of
any such Governmental Authority has or would have the effect of reducing
the rate of return on the capital of such Lender or any corporation
controlling such Lender as a consequence of such Lender's obligations
hereunder to a level below that which such Lender or such corporation
could have achieved but for such adoption, change, request, or directive
(taking into consideration its policies with respect to capital
adequacy), then from time to time upon demand Borrower shall pay to such
Lender such additional amount or amounts as will compensate such Lender
for such reduction.

(c) Each Lender shall promptly notify Borrower and
Administrative Agent of any event of which it has knowledge, occurring
after the date hereof, which will entitle such Lender to compensation
pursuant to this Section and will designate a different Applicable
Lending Office if such designation will avoid the need for, or reduce
the amount of, such compensation and will not, in the judgment of such
Lender, be otherwise disadvantageous to it. Any Lender claiming
compensation under this Section shall furnish to Borrower and
Administrative Agent a statement setting forth the additional amount or
amounts to be paid to it hereunder which shall be conclusive in the
absence of manifest error. In determining such amount, such Lender may
use any reasonable averaging and attribution methods.

4.2 LIMITATION ON TYPES OF LOANS. If on or prior to the first
day of any Interest Period for any Eurodollar Rate Borrowing:

(a) Administrative Agent determines (which determination
shall be conclusive) that by reason of circumstances affecting the
relevant market, adequate and reasonable means do not exist for
ascertaining the Eurodollar Rate for such Interest Period; or

40
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

(b) Required Lenders determine (which determination shall be
conclusive) and notify Administrative Agent that the Adjusted Eurodollar
Rate will not adequately and fairly reflect the cost to the Lenders of
funding Eurodollar Rate Borrowings for such Interest Period;

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

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 make, maintain, or fund Eurodollar Rate
Borrowings hereunder, then such Lender shall promptly notify Borrower thereof
and such Lender's obligation to make or continue Eurodollar Rate Borrowings
and to convert other Base Rate Borrowings into Eurodollar Rate Borrowings
shall be suspended until such time as such Lender may again make, maintain,
and fund Eurodollar Rate Borrowings (in which case the provisions of SECTION
4.4 shall be applicable).

4.4 TREATMENT OF AFFECTED LOANS. If the obligation of any Lender
to fund Eurodollar Rate Borrowings or to continue, or to convert Base Rate
Borrowings into Eurodollar Rate Borrowings, shall be suspended pursuant to
SECTIONS 4.1, 4.2, or 4.3 hereof, such Lender's Eurodollar Rate Borrowings
shall be automatically converted into Base Rate Borrowings on the last day(s)
of the then current Interest Period(s) for Eurodollar Rate Borrowings (or, in
the case of a conversion required by SECTION 4.3 hereof, on such earlier date
as such Lender may specify to Borrower with a copy to Administrative Agent)
and, unless and until such Lender gives notice as provided below that the
circumstances specified in SECTIONS 4.1, 4.2, or 4.3 hereof that gave rise to
such conversion no longer exist:

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

(b) all Borrowings that would otherwise be made or continued
by such Lender as Eurodollar Rate Borrowings shall be made or continued
instead as Base Rate Borrowings, and all Borrowings of such Lender that
would otherwise be converted into Eurodollar Rate Borrowings shall be
converted instead into (or shall remain as) Base Rate Borrowings.

If such Lender gives notice to Borrower (with a copy to Administrative Agent)
that the circumstances specified in SECTIONS 4.1, 4.2, or 4.3 hereof that
gave rise to the conversion of such Lender's Eurodollar Rate Borrowings
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
Rate Borrowings made by other Lenders are outstanding, such Lender's Base
Rate Borrowings shall be automatically converted, on the first day(s) of the
next succeeding Interest Period(s) for such outstanding Eurodollar Rate
Borrowings, to the extent necessary so that, after giving effect thereto, all
Eurodollar Rate Borrowings held by the Lenders and by such Lender are held
pro rata (as to principal amounts, Types, and Interest Periods) in accordance
with their respective Commitments.

4.5 COMPENSATION. Upon the request of any Lender, Borrower shall
pay to such Lender such amount or amounts as shall be sufficient (in the
reasonable opinion of such Lender) to compensate it for any loss, cost, or
expense (including loss of anticipated profits) incurred by it as a result of:

41
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

(a) any payment, prepayment, or conversion of a Eurodollar
Rate Borrowing for any reason (including, without limitation, the
acceleration of the loan pursuant to SECTION 11.1) on a date other than
the last day of the Interest Period for such Borrowing; or

(b) any failure by Borrower for any reason (including,
without limitation, the failure of any condition precedent specified in
SECTION 7.3 to be satisfied) to borrow, convert, continue, or prepay a
Eurodollar Rate Borrowing on the date for such borrowing, conversion,
continuation, or prepayment specified in the relevant notice of
borrowing, prepayment, continuation, or conversion under this Agreement.

4.6 TAXES.

(a) Any and all payments by Borrower to or for the account
of any Lender or Administrative Agent hereunder or under any other Loan
Paper shall be made free and clear of and without deduction for any and
all present or future Taxes, EXCLUDING, in the case of each Lender and
Administrative Agent, Taxes imposed on its income and franchise Taxes
imposed on it by the jurisdiction under the Laws of which such Lender
(or its Applicable Lending Office) or Administrative Agent (as the case
may be) is organized, or any political subdivision thereof. If Borrower
shall be required by Law to deduct any Taxes from or in respect of any
sum payable under this Agreement or any other Loan Paper to any Lender
or Administrative Agent, (i) the sum payable shall be increased as
necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this SECTION 4.6)
such Lender or Administrative Agent receives an amount equal to the sum
it would have received had no such deductions been made, (ii) Borrower
shall make such deductions, (iii) Borrower shall pay the full amount
deducted to the relevant taxation authority or other authority in
accordance with applicable Law, and (iv) Borrower shall furnish to
Administrative Agent, at its address listed in SCHEDULE 2.1, the
original or a certified copy of a receipt evidencing payment thereof.

(b) In addition, Borrower agrees to pay any and all present
or future stamp or documentary taxes and any other excise or property
taxes or charges or similar levies which arise from any payment made
under this Agreement or any other Loan Paper or from the execution or
delivery of, or otherwise with respect to, this Agreement or any other
Loan Paper (hereinafter referred to as "OTHER TAXES").

(c) Borrower agrees to indemnify each Lender and
Administrative Agent for the full amount of Taxes and Other Taxes
(including, without limitation, any Taxes or other Taxes imposed or
asserted by any jurisdiction on amounts payable under this SECTION 4.6)
paid by such Lender or Administrative Agent (as the case may be) and any
liability (including penalties, interest, and expenses) arising
therefrom or with respect thereto.

(d) Each Lender organized under the Laws of a jurisdiction
outside the United States, on or prior to the date of its execution and
delivery of this Agreement in the case of each Lender listed on the
signature pages hereof and on or prior to the date on which it becomes a
Lender in the case of each other Lender, and from time to time
thereafter if requested in writing by Borrower or Administrative Agent
(but only so long as such Lender remains lawfully able to do so), shall
provide Borrower and Administrative Agent with (i) INTERNAL REVENUE
SERVICE FORM 1001 or 4224, as appropriate, or any successor form
prescribed by the Internal Revenue Service, certifying that such Lender
is entitled to benefits under an income tax treaty to which the United
States is a party

42
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

which reduces the rate of withholding tax on payments of interest or
certifying that the income receivable pursuant to this Agreement is
effectively connected with the conduct of a trade or business in the
United States, (ii) INTERNAL REVENUE SERVICE FORM W-8 or W-9, as
appropriate, or any successor form prescribed by the Internal Revenue
Service, and (iii) any other form or certificate required by any
taxing authority (including any certificate required by SECTIONS 871(h)
and 881(c) of the Internal Revenue Code), certifying that such Lender is
entitled to an exemption from or a reduced rate of tax on payments
pursuant to this Agreement or any of the other Loan Papers.

(e) For any period with respect to which a Lender has failed
to provide Borrower and Administrative Agent with the appropriate form
pursuant to SECTION 4.6(d) (unless such failure is due to a change in
Law occurring subsequent to the date on which a form originally was
required to be provided), such Lender shall not be entitled to
indemnification under SECTION 4.6(a) or 4.6(b) with respect to Taxes
imposed by the United States; PROVIDED, HOWEVER, that should a Lender,
which is otherwise exempt from or subject to a reduced rate of
withholding tax, become subject to Taxes because of its failure to
deliver a form required hereunder, Borrower shall take such steps as
such Lender shall reasonably request to assist such Lender to recover
such Taxes.

(f) If Borrower is required to pay additional amounts to or
for the account of any Lender pursuant to this SECTION 4.6, then such
Lender will agree to use reasonable efforts to change the jurisdiction
of its Applicable Lending Office so as to eliminate or reduce any such
additional payment which may thereafter accrue if such change, in the
judgment of such Lender, is not otherwise disadvantageous to such
Lender.

(g) Within thirty (30) days after the date of any payment of
Taxes, Borrower shall furnish to Administrative Agent the original or a
certified copy of a receipt evidencing such payment.

(h) Without prejudice to the survival of any other agreement
of Borrower hereunder, the agreements and obligations of Borrower
contained in this SECTION 4.6 shall survive the termination of the Total
Commitment and the payment in full of the Obligation.

SECTION 5 FEES.

5.1 TREATMENT OF FEES. Except as otherwise provided by Law, the
fees described in this SECTION 5: (a) do not constitute compensation for the
use, detention, or forbearance of money, (b) are in addition to, and not in
lieu of, interest and expenses otherwise described in this Agreement, (c)
shall be payable in accordance with SECTION 3.1, (d) shall be non-refundable,
(e) shall, to the fullest extent permitted by Law, bear interest, if not paid
when due, at the Default Rate, and (f) shall be calculated on the basis of
actual number of days (including the first day but excluding the last day)
elapsed, but computed as if each calendar year consisted of 360 days, unless
such computation would result in interest being computed in excess of the
Maximum Rate in which event such computation shall be made on the basis of a
year of 365 or 366 days, as the case may be.

5.2 FEES OF ADMINISTRATIVE AGENT AND ARRANGER. Borrower shall
pay to (a) Administrative Agent, Lenders, and Arranger, as the case may be,
solely for their respective accounts, the fees described in that certain
separate letter agreement dated as of December 3, 1998, between Borrower,
Administrative Agent, and Arranger, and (b) each of the Agents, all the fees
specified in the letter dated December 9,

43
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

1998, addressed to Borrower from the Agents, which payments shall be made on
the dates specified, and in amounts calculated in accordance with, such
letter agreements.

5.3 REVOLVER FACILITY COMMITMENT FEES. Following the Closing
Date, Borrower shall pay to Administrative Agent, for the ratable account of
Revolver Lenders, a commitment fee, payable in installments in arrears, on
each March 31, June 30, September 30, and December 31 and on the Termination
Date for the Revolver Facility, commencing December 31, 1998. Each
installment shall be, in an amount equal to the Applicable Margin for
Commitment Fees MULTIPLIED BY the amount by which (a) the average daily
Revolver Commitment exceeds (b) the average daily Revolver Commitment Usage,
in each case during the period from and including the last payment date to
and excluding the payment date for such installment; PROVIDED THAT, each such
installment shall be calculated in accordance with SECTION 5.1(f). Solely
for the purposes of this SECTION 5.3, (i) determinations of the average daily
Revolver Commitment Usage shall exclude the Revolver Principal Debt of all
Swing Line Borrowings (provided that, solely for NationsBank in its capacity
as the Lender under the Swing Line Subfacility [and any successor Lender
thereunder, "SWING LINE LENDER"], Borrowings under the Swing Line Subfacility
will be included in determining the Revolver Commitment Usage for such Swing
Line Lender up to, but not in excess of, the amount which causes the Revolver
Commitment Usage of such Swing Line Lender to equal the Committed Sum in
respect of the Revolver Facility of such Lender); and (ii) "RATABLE" shall
mean, for any period of calculation, with respect to any Revolver Lender, that
proportion which (x) the average daily unused Revolver Committed Sum of such
Revolver Lender during such period bears to (y) the amount of the average daily
unused Revolver Commitment during such period.

SECTION 6. SECURITY; GUARANTIES.

6.1 COLLATERAL. To secure full and complete payment and
performance of the Obligation, the Companies hereby jointly and severally
grant and convey to, and create in favor of Administrative Agent for the
ratable benefit of the Lenders, first priority Liens in, to, and on all
assets of the Companies as more particularly described in the Collateral
Documents (the "COLLATERAL"); PROVIDED THAT, no Agent or any Lender hereby
assumes or is made the transferee of any obligations of any Company regarding
any of the Collateral.

6.2 GUARANTIES. As an inducement to Agents and Lenders to enter
into this Agreement, Borrower shall cause Sygnet Communications and each
other Subsidiary to execute and deliver to Administrative Agent a Guaranty
substantially in the form and upon the terms of EXHIBIT C, providing for the
guarantee of payment and performance of the Obligation.

6.3 FUTURE LIENS. Promptly after (a) the acquisition of any
assets (real, personal, tangible, or intangible) by any Company, (b) the
removal, termination, or expiration of any prohibitions upon the granting of
a Lien in any asset (real, personal, tangible, or intangible) of any Company,
or (c) upon the designation, formation, or acquisition of any new Subsidiary
(the assets and stock of such new Subsidiary and the assets described in
CLAUSES (a) and (b) hereof are referred to herein as the "ADDITIONAL
ASSETS"), Borrower shall (or shall cause such other Company to) execute and
deliver to Administrative Agent all further instruments and documents
(including, without limitation, Collateral Documents and all certificates and
instruments representing shares of stock or evidencing Debt and any realty
appraisals as Administrative Agent may require with respect to any such
Additional Assets), and shall take all further action that may be necessary
or desirable, or that Administrative Agent may reasonably request, to grant,
perfect, and protect Liens in favor of Administrative Agent for the benefit
of the Lenders in such Additional Assets, as security for the Obligation; IT
BEING EXPRESSLY UNDERSTOOD that the granting of such additional security

44
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

for the Obligation is a material inducement to the execution and delivery of
this Agreement by each Lender. Upon satisfying the terms and conditions
hereof, such Additional Assets shall be included in the "COLLATERAL" for all
purposes under the Loan Papers, and all references to the "COLLATERAL" in the
Loan Papers shall include the Additional Assets.

6.4 RELEASE OF COLLATERAL. Upon any sale, transfer, or
disposition of Collateral which is expressly permitted pursuant to the Loan
Papers (or is otherwise authorized by Required Lenders or Lenders, as the
case may be), and upon ten (10) Business Days' prior written request by
Borrower (which request must be accompanied by true and correct copies of (a)
all documents of transfer or disposition, including any contract of sale, (b)
a preliminary closing statement and instructions to the title company, if
any, and (c) all requested release instruments), Administrative Agent shall
(and is hereby irrevocably authorized by the Lenders to) execute such
documents as may be necessary to evidence the release of Liens granted to
Administrative Agent for the benefit of Lenders pursuant hereto in such
Collateral; PROVIDED THAT, (i) no such release of Lien shall be granted if
any Default or Potential Default has occurred and is continuing, including,
without limitation, the failure to make certain mandatory prepayments in
accordance with SECTIONS 2.7(b)(ii) in conjunction with the sale or transfer
of such Collateral; (ii) Administrative Agent shall not be required to
execute any such document on terms which, in Administrative Agent's opinion,
would expose Administrative Agent to liability or create any obligation or
entail any consequence OTHER THAN the release of such Liens without recourse
or warranty; and (iii) such release shall not in any manner discharge,
affect, or impair the Obligation, or Liens upon (or obligations of any
Company in respect of) all interests retained by the Companies, including
(without limitation) the proceeds of any sale, all of which shall continue to
constitute Collateral.

6.5 NEGATIVE PLEDGE. Notwithstanding the provisions of SECTION
6.1 hereof, until such time as Administrative Agent or Required Lenders
otherwise require, the Companies shall not be required to: (i) perfect Liens
on certain assets constituting interests in assigned leases (other than the
Sygnet Towers Lease), vehicles, fixtures, or real estate, SO LONG AS the
aggregate value of such assets does not exceed $5,000,000, or (ii) to grant
specific assignments of easements, licenses, permits, certificates of
compliance, and certificates of approval issued by regulatory authorities,
franchises, or like grants of authority or service agreements, To the extent
Administrative Agent and Required Lenders agree to delay the perfection or
attachment of any Lien granted pursuant to SECTION 6.1 hereof, for whatever
reason, the Companies hereby covenant and agree not to directly create,
incur, grant, suffer, or permit to be created or incurred any Lien on any
such assets, OTHER THAN Permitted Liens. Furthermore, within thirty (30)
days of the request of Administrative Agent, Borrower shall (or shall cause
each Company to) execute and deliver to Administrative Agent all instruments
and documents (including, without limitation, certificates and instruments
and documents representing shares of stock or evidencing Debt) and shall take
all further action that may be necessary or desirable, or that Administrative
Agent may reasonably request, to grant, perfect, and protect Liens in favor
of Administrative Agent for the benefit of Lenders, in such assets, as
security for the Obligation; IT BEING EXPRESSLY UNDERSTOOD that the
provisions of this negative pledge are a material inducement to the execution
and delivery of this Agreement by each Lender.

6.6 CONTROL; LIMITATION OF RIGHTS. Notwithstanding anything
herein or in any other Loan Paper to the contrary, (a) the transactions
contemplated hereby (i) do not and will not constitute, create, or have the
effect of constituting or creating, directly or indirectly, actual or
practical ownership of the Companies by Agents or Lenders, or control,
affirmative or negative, direct or indirect, by Agents or Lenders over the
management or any other aspect of the operation of the Companies, which
ownership or control remains exclusively and at all times in the Companies,
and (ii) do not and will not constitute the transfer, assignment, or
disposition in any manner, voluntary or involuntary, directly or indirectly,
of any

45
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

Authorization at any time issued by the FCC or any PUC to the Companies, or
the transfer of control of the Companies within the meaning of SECTION 310(d)
of the Communications Act; and (b) Administrative Agent shall not, without
first obtaining the approval of the FCC or any applicable PUC, take any
action pursuant to this Agreement or any other Loan Paper that would
constitute or result in any assignment of any Authorization or any change of
control of the Companies, if such assignment or change of control would
require, under then existing Law (including the written rules and regulations
promulgated by the FCC or any such PUC), the prior approval of the FCC or any
such PUC.

SECTION 7 CONDITIONS PRECEDENT.

7.1 CONDITIONS PRECEDENT TO CLOSING. This Agreement shall not
become effective, and Lenders shall not be obligated to advance any
Borrowing, unless Administrative Agent has received all of the agreements,
documents, instruments, and other items described on SCHEDULE 7.1.

7.2 CONDITIONS PRECEDENT TO A PERMITTED ACQUISITION. On or prior
to the consummation of any Acquisition (whether or not the purchase price for
such Acquisition is funded by Borrowings), Borrower shall have satisfied the
conditions and delivered, or caused to be delivered, to Administrative Agent,
all documents and certificates set forth on SCHEDULE 7.2 by no later than the
dates specified for satisfaction of such conditions on SCHEDULE 7.2.
Promptly upon receipt of each Permitted Acquisition Compliance Certificate
and each Permitted Acquisition Loan Closing Certificate, Administrative Agent
shall provide copies of such certificates to Lenders. All documentation
delivered and satisfaction of conditions pursuant to the requirements of
SECTION 7.2 must be satisfactory to Administrative Agent. To the extent any
Borrowing is being requested in connection with the consummation of the
Acquisition, the conditions set forth in SECTIONS 7.2 and 7.3 hereof must be
satisfied prior to the making of any such Borrowing.

7.3 CONDITIONS PRECEDENT TO EACH BORROWING. In addition to the
conditions stated in SECTIONS 7.1 and 7.2, Lenders will not be obligated to
fund (as opposed to continue or convert) any Borrowing, unless on the date of
such Borrowing (and after giving effect thereto): (a) Administrative Agent
shall have timely received therefor a Notice of Borrowing; (b) all of the
representations and warranties of any Company set forth in the Loan Papers
are true and correct in all material respects (except to the extent that (i)
the representations and warranties speak to a specific date or (ii) the facts
on which such representations and warranties are based have been changed by
transactions contemplated or permitted by the Loan Papers); (c) no change in
the financial condition or business of any Company which could be a Material
Adverse Event shall have occurred; (d) no Default or Potential Default shall
have occurred and be continuing; (e) the funding of such Borrowings is
permitted by Law; (f) in the event all or any part of the proceeds of the
Borrowing will be used to finance a Distribution to the extent permitted by
SECTION 9.21, Administrative Agent shall have received all such
certifications, financial information, and projections as Administrative
Agent may reasonably request; and (g) all matters related to such Borrowing
must be satisfactory to Required Lenders and their respective counsel in
their reasonable determination, and upon the reasonable request of
Administrative Agent, Borrower shall deliver to Administrative Agent evidence
substantiating any of the matters in the Loan Papers which are necessary to
enable Borrower to qualify for such Borrowing. Each Notice of Borrowing
delivered to Administrative Agent shall constitute the representation and
warranty by Borrower to Administrative Agent that the statements above are
true and correct in all respects. Each condition precedent in this Agreement
is material to the transactions contemplated in this Agreement, and time is
of the essence in respect of each thereof. Subject to the prior approval of
Required Lenders, Lenders may fund any Borrowing without all conditions being
satisfied, but, to the extent permitted by Law, the same shall not be deemed
to be a waiver of the requirement that each

46
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

such condition precedent be satisfied as a prerequisite for any subsequent
funding or issuance, unless Required Lenders specifically waive each such
item in writing.

SECTION 8 REPRESENTATIONS AND WARRANTIES. Borrower and each other
Company represent and warrant to Administrative Agent and Lenders as follows:

8.1 PURPOSE OF CREDIT FACILITIES. Borrower will use (or will
loan such proceeds to its Companies to so use) all proceeds of Borrowings for
one or more of the following: (a) to finance all or a portion of the Sygnet
Merger and the related costs and expenses; (b) to finance other Permitted
Acquisitions; (c) to refinance certain indebtedness of Sygnet Wireless, Inc.
existing as of the Closing Date, including the Sygnet Senior Notes; (d) to
finance Capital Expenditures; (e) to finance certain investments permitted by
the Loan Papers; (f) to finance certain permitted Distributions; (g) for
working capital of Borrower and its Subsidiaries; and (h) for general
corporate purposes. No Company is engaged principally, or as one of its
important activities, in the business of extending credit for the purpose of
purchasing or carrying any "MARGIN STOCK" within the meaning of REGULATION U.
No part of the proceeds of any Borrowing will be used, directly or
indirectly, for a purpose which violates any Law, including, without
limitation, the provisions of REGULATIONS T, U, or X (as enacted by the Board
of Governors of the Federal Reserve System, as amended).

8.2 EXISTENCE, GOOD STANDING, AUTHORITY, AND AUTHORIZATIONS.
Each Company is duly organized, validly existing, and in good standing under
the Laws of its jurisdiction of organization (such jurisdictions being
identified on SCHEDULE 8.3, as supplemented and modified in writing from time
to time to reflect any changes to such Schedule as a result of transactions
permitted by the Loan Papers). Each Company is duly qualified to transact
business and is in good standing in each jurisdiction where the nature and
extent of its business and properties require the same. Each of the
Companies possesses all Authorizations, franchises, permits, licenses,
certificates of compliance, and approvals and grants of authority necessary,
including, without limitation, any Authorization issued by the FCC, all of
which are described on SCHEDULE 8.2 hereto, necessary or required in the
conduct of its respective business(es), and the same are valid, binding,
enforceable, and subsisting without any defaults thereunder or enforceable
adverse limitations thereon and are not subject to any proceedings or claims
opposing the issuance, development, or use thereof or contesting the validity
thereof. No authorization, consent, approval, waiver, license, or formal
exemptions from, nor any filing, declaration, or registration with, any
Governmental Authority (federal, state, or local), or non-governmental
entity, under the terms of contracts or otherwise, is required by reason of
or in connection with the execution and performance of the Loan Papers by the
Companies or consummation of the Sygnet Merger, except as shall have been
obtained on or prior to the Closing Date.

8.3 SUBSIDIARIES; CAPITAL STOCK. The Companies have no
Subsidiaries except as disclosed on SCHEDULE 8.3 (as supplemented and
modified in writing from time to time to reflect any changes to such Schedule
as a result of transactions permitted by the Loan Papers). All of the
outstanding shares of capital stock (or similar voting interests) of each
Subsidiary are duly authorized, validly issued, fully paid, and nonassessable
and are owned of record and beneficially as set forth on SCHEDULE 8.3 (as
supplemented and modified in writing from time to time to reflect any changes
to such Schedule as a result of transactions permitted by the Loan Papers),
free and clear of any Liens, restrictions, claims, or rights of another
Person, other than Permitted Liens, and none of such shares owned by any
Company is subject to any restriction on transfer thereof except for
restrictions imposed by securities Laws and general corporate Laws. No
Company has outstanding any warrant, option, or other right of any Person to
acquire any of its capital stock or similar equity interests.

47
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

8.4 AUTHORIZATION AND CONTRAVENTION. The execution and delivery
by each Company of each Loan Paper to which it is a party and the performance
by such Company of its obligations thereunder (a) are within the corporate
power of such Company, (b) will have been duly authorized by all necessary
corporate or partnership action on the part of such Company when such Loan
Paper is executed and delivered, (c) require no action by or in respect of,
or filing with, any Governmental Authority, which action or filing has not
been taken or made on or prior to the Closing Date (or if later, the date of
execution and delivery of such Loan Paper), (d) will not violate any
provision of the charter, bylaws, or partnership agreement of such Company,
(e) will not violate any provision of Law applicable to it, other than such
violations which individually or collectively could not be a Material Adverse
Event, (f) will not violate any material written or oral agreements,
contracts, commitments, or understandings to which it is a party, other than
such violations which could not be a Material Adverse Event, or (g) will not
result in the creation or imposition of any Lien on any asset of any Company.
The Companies have (or will have upon consummation thereof) all necessary
consents and approvals of any Person or Governmental Authority required to be
obtained in order to effect the Sygnet Merger and any other any asset
transfer, change of control, merger, or consolidation permitted by the Loan
Papers.

8.5 BINDING EFFECT. Upon execution and delivery by all parties
thereto, each Loan Paper will constitute a legal, valid, and binding
obligation of each Company party thereto, enforceable against each such
Company in accordance with its terms, except as enforceability may be limited
by applicable Debtor Relief Laws and general principles of equity.

8.6 FINANCIAL STATEMENTS. The Current Financials were prepared
in accordance with GAAP and present fairly, in all material respects, the
consolidated financial condition, results of operations, and cash flows of
the Companies as of and for the portion of the fiscal year ending on the date
or dates thereof (subject only to normal year-end audit adjustments). There
were no material liabilities, direct or indirect, fixed or contingent, of the
Companies as of the date or dates of the Current Financials which are
required under GAAP to be reflected therein or in the notes thereto, and are
not so reflected. Except for transactions directly related to, or
specifically contemplated by, the Loan Papers, there have been no changes in
the consolidated financial condition of the Companies from that shown in the
Current Financials after such date which could be a Material Adverse Event,
nor has Borrower or any Company incurred any liability (including, without
limitation, any liability under any Environmental Law), direct or indirect,
fixed or contingent, after such date which could be a Material Adverse Event.

8.7 LITIGATION, CLAIMS, INVESTIGATIONS. No Company is subject
to, or aware of the threat of, any Litigation which is reasonably likely to
be determined adversely to any Company, and, if so adversely determined,
could (individually or collectively with other Litigation) be a Material
Adverse Event. There are no outstanding orders or judgments for the payment
of money in excess of $1,000,000 (individually or collectively) or any

each Company which are due and payable have been paid prior to delinquency,
OTHER THAN Taxes for which the criteria for Permitted Liens (as specified in

any Hazardous Substance, on any property presently or previously owned by any
Company that could be a Material Adverse Event, (b) knows of any violation by
any Company of any Environmental Law, except for such violations that could
not be a Material Adverse Event, or (c) knows that any Company is under any
obligation to remedy any violation of any Environmental Law, except for such
obligations that could not be a Material Adverse Event; PROVIDED, HOWEVER,
that each Company (x) to the best of its knowledge, has in full force and

result in the termination of an Employee Plan. The present value of all

Employee Plan (based on those actuarial assumptions used to fund such
Employee Plan) did not, as of the last annual valuation date for the 1997
plan year of such Plan, exceed the value of the assets of such Employee Plan,
and the total present values of all benefit liabilities within the meaning of
TITLE IV of ERISA of all Employee Plans (based on the actuarial assumptions

in title which, when considered in the aggregate, would not be a Material
Adverse Event, or (b) as otherwise permitted by the Loan Papers. Except for
Permitted Liens, there is no Lien on any property of any Company, and the
execution, delivery, performance, or observance of the Loan Papers will not
require or result in the creation of any Lien on such property.

not been in violation of the FAIR LABOR STANDARDS ACT or any other applicable
Law dealing with such matters, other than any such violations, individually
or collectively, which could not constitute a Material Adverse Event. All
payments due from any Company on account of employee health and welfare
insurance have been paid or accrued as a liability on its books, other than
any such nonpayments which could not, individually or collectively,
constitute a Material Adverse Event.

infringement of any license, patent, copyright, service ▇▇▇▇, trademark,
trade name, trade secret, or other intellectual property right of others,

SECTION 11 RIGHTS AND REMEDIES.

11.1 REMEDIES UPON DEFAULT.

(a) If a Default exists under SECTIONS 10.3(c) or 10.3(d),
the commitment to extend credit hereunder shall automatically terminate
and the entire unpaid balance of the Obligation shall automatically
become due and payable without any action or notice of any kind
whatsoever.

(b) If any Default exists, Administrative Agent shall, upon
the request of Required Lenders (subject to the terms of SECTION 12) or
Required Lenders may, do any one or more of the following: (i) if the
maturity of the Obligation has not already been accelerated under
SECTION 11.1(a), declare the entire unpaid balance of the Obligation, or
any part thereof, immediately due and payable, whereupon it shall be due
and payable; (ii) terminate the commitments of Lenders to extend credit
hereunder; (iii) reduce any claim to judgment; (iv) to the extent
permitted by Law, exercise (or request each Lender to, and each Lender
shall be entitled to, exercise) the Rights of offset or banker's Lien
against the interest of each Company in and to every account and other
property of each Company which are in the possession of Administrative
Agent or any Lender to the extent of the full amount of the Obligation
(to the extent permitted by Law, each Company being deemed directly
obligated to each Lender in the full amount of the Obligation for such
purposes); and (v) exercise any and all other legal or equitable Rights
afforded by the Loan Papers, the Laws of the State of Texas, or any
other applicable jurisdiction as Administrative Agent shall deem
appropriate, or otherwise, including, but not limited to, the Right to
bring suit or other proceedings before any Governmental Authority either
for specific performance of any covenant or condition contained in any
of the Loan Papers or in aid of the exercise of any Right granted to
Administrative Agent or any Lender in any of the Loan Papers.

11.2 COMPANY WAIVERS. To the extent permitted by Law, the Companies
hereby waive presentment and demand for payment, protest, notice of intention to
accelerate, notice of acceleration, and notice of protest and nonpayment, and
agree that their respective liability with respect to the Obligation (or any
part thereof) shall not be affected by any renewal or extension in the time of
payment of the

67
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

Obligation (or any part thereof), by any indulgence, or by any release or
change in any security for the payment of the Obligation (or any part
thereof).

11.3 PERFORMANCE BY ADMINISTRATIVE AGENT. If any covenant, duty, or
agreement of any Company is not performed in accordance with the terms of the
Loan Papers, after the occurrence and during the continuance of a Default,
Administrative Agent may, at its option (but subject to the approval of Required
Lenders), perform or attempt to perform such covenant, duty, or agreement on
behalf of such Company. In such event, any amount expended by Administrative
Agent in such performance or attempted performance shall be payable by the
Companies, jointly and severally, to Administrative Agent on demand, shall
become part of the Obligation, and shall bear interest at the Default Rate from
the date of such expenditure by Administrative Agent until paid.
Notwithstanding the foregoing, it is expressly understood that Administrative
Agent does not assume, and shall never have, except by its express written
consent, any liability or responsibility for the performance of any covenant,
duty, or agreement of any Company.

11.4 DELEGATION OF DUTIES AND RIGHTS. Lenders may perform any of
their duties or exercise any of their Rights under the Loan Papers by or through
their respective Representatives.

11.5 NOT IN CONTROL. Nothing in any Loan Paper shall, or shall be
deemed to (a) give any Agent or any Lender the Right to exercise control over
the assets (including real property), affairs, or management of any Company, (b)
preclude or interfere with compliance by any Company with any Law, or (c)
require any act or omission by any Company that may be harmful to Persons or
property. Any "MATERIAL ADVERSE EVENT" or other materiality qualifier in any
representation, warranty, covenant, or other provision of any Loan Paper is
included for credit documentation purposes only and shall not, and shall not be
deemed to, mean that any Agent or any Lender acquiesces in any non-compliance by
any Company with any Law or document, or that any Agent or any Lender does not
expect the Companies to promptly, diligently, and continuously carry out all
appropriate removal, remediation, and termination activities required or
appropriate in accordance with all Environmental Laws. The Agents and the
Lenders have no fiduciary relationship with or fiduciary duty to Borrower or any
Company arising out of or in connection with the Loan Papers, and the
relationship between the Agents and the Lenders, on the one hand, and Borrower
and the Companies, on the other hand, in connection with the Loan Papers is
solely that of debtor and creditor. The power of the Agents and Lenders under
the Loan Papers is limited to the Rights provided in the Loan Papers, which
Rights exist solely to assure payment and performance of the Obligation and may
be exercised in a manner calculated by the Agents and Lenders in their
respective good faith business judgment.

11.6 COURSE OF DEALING. The acceptance by Administrative Agent or
Lenders at any time and from time to time of partial payment on the Obligation
shall not be deemed to be a waiver of any Default then existing. No waiver by
Administrative Agent, Required Lenders, or Lenders of any Default shall be
deemed to be a waiver of any other then-existing or subsequent Default. No
delay or omission by Administrative Agent, Required Lenders, or Lenders in
exercising any Right under the Loan Papers shall impair such Right or be
construed as a waiver thereof or any acquiescence therein, nor shall any single
or partial exercise of any such Right preclude other or further exercise
thereof, or the exercise of any other Right under the Loan Papers or otherwise.

11.7 CUMULATIVE RIGHTS. All Rights available to Administrative Agent
and Lenders under the Loan Papers are cumulative of and in addition to all other
Rights granted to Administrative Agent and Lenders at law or in equity, whether
or not the Obligation is due and payable and whether or not

68
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

Administrative Agent or Lenders have instituted any suit for collection,
foreclosure, or other action in connection with the Loan Papers.

11.8 APPLICATION OF PROCEEDS. Any and all proceeds ever received by
Administrative Agent or Lenders from the exercise of any Rights pertaining to
the Obligation shall be applied to the Obligation in the order and manner set
forth in SECTION 3.11.

11.9 CERTAIN PROCEEDINGS. Each Company will promptly execute and
deliver, or cause the execution and delivery of, all applications, certificates,
instruments, registration statements, and all other documents and papers
Administrative Agent or Lenders may reasonably request in connection with the
obtaining of any consent, approval, registration, qualification, permit,
license, or Authorization of any Governmental Authority or other Person
necessary or appropriate for the effective exercise of any Rights under the Loan
Papers. Because the Companies agree that Administrative Agent's and Lenders'
remedies at Law for failure of the Companies to comply with the provisions of
this Section would be inadequate and that such failure would not be adequately
compensable in damages, the Companies agree that the covenants of this Section
may be specifically enforced.

11.10 LIMITATION OF RIGHTS. Notwithstanding any other provision of
this Agreement or any other Loan Paper, any action taken or proposed to be taken
by Administrative Agent, any Agent, or any Lender under any Loan Paper which
would affect the operational, voting, or other control of any Company, shall be
pursuant to SECTION 310(d) of the COMMUNICATIONS ACT OF 1934 (as amended), any
applicable state Law, and the applicable rules and regulations thereunder and,
if and to the extent required thereby, subject to the prior consent of the FCC
or any applicable PUC.

11.11 EXPENDITURES BY LENDERS. Borrower shall promptly pay within
fifteen (15) Business Days after request therefor (a) all reasonable costs,
fees, and expenses paid or incurred by Administrative Agent and Arranger,
incident to any Loan Paper (including, but not limited to, the reasonable fees
and expenses of counsel to Administrative Agent and Arranger and the allocated
cost of internal counsel in connection with the negotiation, preparation,
delivery, execution, coordination and administration of the Loan Papers and any
related amendment, waiver, or consent) and (b) all reasonable costs and expenses
of Lenders and Administrative Agent incurred by Administrative Agent or any
Lender in connection with the enforcement of the obligations of any Company
arising under the Loan Papers (including, without limitation, costs and expenses
incurred in connection with any workout or bankruptcy) or the exercise of any
Rights arising under the Loan Papers (including, but not limited to, reasonable
attorneys' fees including allocated cost of internal counsel, court costs and
other costs of collection), all of which shall be a part of the Obligation and
shall bear interest at the Default Rate from the date due until the date repaid.

11.12 INDEMNIFICATION. BORROWER AND EACH COMPANY AGREE TO INDEMNIFY
AND HOLD HARMLESS EACH AGENT, ARRANGER, AND EACH LENDER AND EACH OF THEIR
RESPECTIVE AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES,
AGENTS, ATTORNEYS, AND ADVISORS (EACH, AN "INDEMNIFIED PARTY") FROM AND AGAINST
ANY AND ALL CLAIMS, DAMAGES, LOSSES, LIABILITIES, COSTS, AND EXPENSES
(INCLUDING, WITHOUT LIMITATION, REASONABLE ATTORNEYS' FEES) THAT MAY BE INCURRED
BY OR ASSERTED OR AWARDED AGAINST ANY INDEMNIFIED PARTY, IN EACH CASE ARISING
OUT OF OR IN CONNECTION WITH OR BY REASON OF (INCLUDING, WITHOUT LIMITATION, IN
CONNECTION WITH ANY INVESTIGATION, LITIGATION, OR PROCEEDING OR PREPARATION OF
DEFENSE IN CONNECTION THEREWITH) THE LOAN PAPERS, ANY OF THE TRANSACTIONS
CONTEMPLATED HEREIN OR THE ACTUAL OR PROPOSED USE OF THE PROCEEDS OF THE
BORROWINGS (INCLUDING ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF THE
INDEMNIFIED PARTY), EXCEPT TO THE EXTENT SUCH CLAIM, DAMAGE,

69
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

LOSS, LIABILITY, COST, OR EXPENSE IS FOUND IN A FINAL, NON-APPEALABLE
JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM SUCH
INDEMNIFIED PARTY'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. IN THE CASE OF
AN INVESTIGATION, LITIGATION OR OTHER PROCEEDING TO WHICH THE INDEMNITY IN
THIS SECTION 11.12 APPLIES, SUCH INDEMNITY SHALL BE EFFECTIVE WHETHER OR NOT
SUCH INVESTIGATION, LITIGATION OR PROCEEDING IS BROUGHT BY THE BORROWER, ITS
DIRECTORS, SHAREHOLDERS OR CREDITORS OR AN INDEMNIFIED PARTY OR ANY OTHER
PERSON OR ANY INDEMNIFIED PARTY IS OTHERWISE A PARTY THERETO AND WHETHER OR
NOT THE TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED. BORROWER AND EACH
COMPANY AGREE NOT TO ASSERT ANY CLAIM AGAINST ANY INDEMNIFIED PARTY ON ANY
THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL, OR PUNITIVE
DAMAGES ARISING OUT OF OR OTHERWISE RELATING TO THE LOAN PAPERS, ANY OF THE
TRANSACTIONS CONTEMPLATED HEREIN OR THE ACTUAL OR PROPOSED USE OF THE
PROCEEDS OF THE BORROWINGS. WITHOUT PREJUDICE TO THE SURVIVAL OF ANY OTHER
AGREEMENT OF THE BORROWER HEREUNDER, THE AGREEMENTS AND OBLIGATIONS OF THE
BORROWER CONTAINED IN THIS SECTION 11.12 SHALL SURVIVE THE PAYMENT IN FULL OF
THE BORROWINGS AND ALL OTHER AMOUNTS PAYABLE UNDER THIS AGREEMENT.

SECTION 12 AGREEMENT AMONG LENDERS.

12.1 ADMINISTRATIVE AGENT.

(a) Each Lender hereby appoints NationsBank, N.A. (and
NationsBank, N.A. hereby accepts such appointment) as its nominee and
agent, in its name and on its behalf: (i) to act as nominee for and on
behalf of such Lender in and under all Loan Papers; (ii) to arrange the
means whereby the funds of Lenders are to be made available to Borrower
under the Loan Papers; (iii) to take such action as may be requested by
any Lender under the Loan Papers (when such Lender is entitled to make
such request under the Loan Papers and after such requesting Lender has
obtained the concurrence of such other Lenders as may be required under
the Loan Papers); (iv) to receive all documents and items to be
furnished to Lenders under the Loan Papers; (v) to timely distribute,
and Administrative Agent agrees to so distribute, to each Lender all
material information, requests, documents, and items received from
Borrower under the Loan Papers; (vi) to promptly distribute to each
Lender its ratable part of each payment or prepayment (whether
voluntary, as proceeds of collateral upon or after foreclosure, as
proceeds of insurance thereon, or otherwise) in accordance with the
terms of the Loan Papers; (vii) to deliver to the appropriate Persons
requests, demands, approvals, and consents received from Lenders; and
(viii) to execute, on behalf of Lenders, such releases or other
documents or instruments as are permitted by the Loan Papers or as
directed by Lenders from time to time; PROVIDED, HOWEVER, Administrative
Agent shall not be required to take any action which exposes
Administrative Agent to personal liability or which is contrary to the
Loan Papers or applicable Law.

(b) Administrative Agent may resign at any time as
Administrative Agent under the Loan Papers by giving written notice
thereof to Lenders and may be removed as Administrative Agent under the
Loan Papers at any time with cause by Required Lenders. Should the
initial or any successor Administrative Agent ever cease to be a party
hereto or should the initial or any successor Administrative Agent ever
resign or be removed as Administrative Agent, then Required Lenders
shall elect the successor Administrative Agent from among the Lenders
(other than the resigning Administrative Agent). If no successor
Administrative Agent shall have been so appointed by Required Lenders,
within 30 days after the retiring Administrative Agent's giving of
notice of resignation or Required Lenders' removal of the retiring
Administrative Agent, then

70
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

the retiring Administrative Agent may, on behalf of Lenders, appoint
a successor Administrative Agent, which shall be a commercial bank
having a combined capital and surplus of at least $1,000,000,000.
Upon the acceptance of any appointment as Administrative Agent under
the Loan Papers by a successor Administrative Agent, such successor
Administrative Agent shall thereupon succeed to and become vested
with all the Rights of the retiring Administrative Agent, and the
retiring Administrative Agent shall be discharged from its duties and
obligations of Administrative Agent under the Loan Papers, and each
Lender shall execute such documents as any Lender may reasonably
request to reflect such change in and under the Loan Papers. After
any retiring Administrative Agent's resignation or removal as
Administrative Agent under the Loan Papers, the provisions of this
SECTION 12 shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Administrative Agent under the
Loan Papers.

(c) Administrative Agent, in its capacity as a Lender, shall
have the same Rights under the Loan Papers as any other Lender and may
exercise the same as though it were not acting as Administrative Agent;
the term "LENDER" shall, unless the context otherwise indicates, include
Administrative Agent; and any resignation, or removal of by
Administrative Agent hereunder shall not impair or otherwise affect any
Rights which it has or may have in its capacity as an individual Lender.
Each Lender and Borrower agree that Administrative Agent is not a
fiduciary for Lenders or for Borrower but simply is acting in the
capacity described herein to alleviate administrative burdens for both
Borrower and Lenders, that Administrative Agent has no duties or
responsibilities to Lenders or Borrower except those expressly set forth
herein, and that Administrative Agent in its capacity as a Lender has
all Rights of any other Lender.

(d) Administrative Agent and its Affiliates may now or
hereafter be engaged in one or more loan, letter of credit, leasing, or
other financing transactions with Borrower, act as trustee or depositary
for Borrower, or otherwise be engaged in other transactions with
Borrower (collectively, the "OTHER ACTIVITIES") not the subject of the
Loan Papers. Without limiting the Rights of Lenders specifically set
forth in the Loan Papers, Administrative Agent and its Affiliates shall
not be responsible to account to Lenders for such other activities, and
no Lender shall have any interest in any other activities, any present
or future guaranties by or for the account of Borrower which are not
contemplated or included in the Loan Papers, any present or future
offset exercised by Administrative Agent and its Affiliates in respect
of such other activities, any present or future property taken as
security for any such other activities, or any property now or hereafter
in the possession or control of Administrative Agent or its Affiliates
which may be or become security for the obligations of Borrower arising
under the Loan Papers by reason of the general description of
indebtedness secured or of property contained in any other agreements,
documents or instruments related to any such other activities; PROVIDED
THAT, if any payments in respect of such guaranties or such property or
the proceeds thereof shall be applied to reduction of the obligations of
Borrower arising under the Loan Papers, then each Lender shall be
entitled to share in such application ratably.

12.2 EXPENSES. Upon demand by Administrative Agent, each Lender
shall pay its Pro Rata Part of any reasonable expenses (including, without
limitation, court costs, reasonable attorneys' fees, and other costs of
collection) incurred by Administrative Agent in connection with any of the Loan
Papers if and to the extent Administrative Agent does not receive reimbursement
therefor from other sources within 60 days after incurred; PROVIDED THAT, each
Lender shall be entitled to receive its Pro Rata Part of any reimbursement for
such expenses, or part thereof, which Administrative Agent subsequently receives
from such other sources.

71
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

12.3 PROPORTIONATE ABSORPTION OF LOSSES. Except as otherwise
provided in the Loan Papers, nothing in the Loan Papers shall be deemed to give
any Lender any advantage over any other Lender insofar as the Obligation arising
under the Loan Papers is concerned, or to relieve any Lender from absorbing its
Pro Rata Part of any losses sustained with respect to the Obligation (except to
the extent such losses result from unilateral actions or inactions of any Lender
that are not made in accordance with the terms and provisions of the Loan
Papers).

12.4 DELEGATION OF DUTIES; RELIANCE. Administrative Agent may
perform any of its duties or exercise any of its Rights under the Loan Papers by
or through its Representatives. Administrative Agent and its Representatives
shall (a) be entitled to rely upon (and shall be protected in relying upon) any
writing, resolution, notice, consent, certificate, affidavit, letter, cablegram,
telecopy, telegram, telex or teletype message, statement, order, or other
documents or conversation believed by it or them to be genuine and correct and
to have been signed or made by the proper Person and, with respect to legal
matters, upon opinion of counsel selected by Administrative Agent, (b) be
entitled to deem and treat each Lender as the owner and holder of the Principal
Debt owed to such Lender for all purposes until, subject to SECTION 13.13,
written notice of the assignment or transfer thereof shall have been given to
and received by Administrative Agent (and any request, authorization, consent,
or approval of any Lender shall be conclusive and binding on each subsequent
holder, assignee, or transferee of the Principal Debt owed to such Lender or
portion thereof until such notice is given and received), (c) not be deemed to
have notice of the occurrence of a Default unless a responsible officer of
Administrative Agent, who handles matters associated with the Loan Papers and
transactions thereunder, has received written notice from a Lender or Borrower
and stating that such notice is a "NOTICE OF DEFAULT," and (d) be entitled to
consult with legal counsel (including counsel for Borrower), independent
accountants, and other experts selected by Administrative Agent 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.

12.5 LIMITATION OF LIABILITY.

(a) None of the Agents or any of their respective
Representatives shall be liable for any action taken or omitted to be
taken by it or them under the Loan Papers in good faith and reasonably
believed by it or them to be within the discretion or power conferred
upon it or them by the Loan Papers or be responsible for the
consequences of any error of judgment, except for fraud, gross
negligence, or willful misconduct; and none of the Agents or any of
their respective Representatives has a fiduciary relationship with any
Lender by virtue of the Loan Papers (PROVIDED THAT, nothing herein shall
negate the obligation of Administrative Agent or Administrative Agent to
account for funds received by it for the account of any Lender).

(b) Unless indemnified to its satisfaction against loss,
cost, liability, and expense, neither Administrative Agent nor any other
Agent shall be compelled to do any act under the Loan Papers or to take
any action toward the execution or enforcement of the powers thereby
created or to prosecute or defend any suit in respect of the Loan
Papers. If Administrative Agent requests instructions from Lenders or
Required Lenders, as the case may be, with respect to any act or action
(including, but not limited to, any failure to act) in connection with
any Loan Paper, Administrative Agent shall be entitled (but shall not be
required) to refrain (without incurring any liability to any Person by
so refraining) from such act or action unless and until it has received
such instructions. Except where action of Required Lenders or all
Lenders is required in the Loan Papers, Administrative Agent may act
hereunder in its own discretion without requesting instructions. In no
event, however, shall Administrative Agent or any of its respective

72
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

Representatives be required to take any action which it or they
determine could incur for it or them criminal or onerous civil
liability. Without limiting the generality of the foregoing, no Lender
shall have any right of action against Administrative Agent as a result
of Administrative Agent's acting or refraining from acting hereunder in
accordance with the instructions of Required Lenders (or all Lenders if
required in the Loan Papers).

(c) Administrative Agent nor any other Agent shall be
responsible in any manner to any Lender or any Participant for, and each
Lender represents and warrants that it has not relied upon
Administrative Agent or any other Agent in respect of, (i) the
creditworthiness of any Company and the risks involved to such Lender,
(ii) the effectiveness, enforceability, genuineness, validity, or the
due execution of any Loan Paper, (iii) any representation, warranty,
document, certificate, report, or statement made therein or furnished
thereunder or in connection therewith, (iv) the existence, priority, or
perfection of any Lien hereafter granted or purported to be granted
under any Loan Paper, or (v) observation of or compliance with any of
the terms, covenants, or conditions of any Loan Paper on the part of any
Company. Each Lender agrees to indemnify Administrative Agent and its
respective Representatives and hold them harmless from and against (but
limited to such Lender's Pro Rata Part of) any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits,
costs, reasonable expenses, and reasonable disbursements of any kind or
nature whatsoever which may be imposed on, asserted against, or incurred
by them in any way relating to or arising out of the Loan Papers or any
action taken or omitted by them under the Loan Papers (INCLUDING ANY OF
THE FOREGOING ARISING FROM THE NEGLIGENCE OF ADMINISTRATIVE AGENT OR ITS
REPRESENTATIVES), to the extent Administrative Agent and its respective
Representatives are not reimbursed for such amounts by any Company
(PROVIDED THAT, Administrative Agent, and its respective Representatives
shall not have the right to be indemnified hereunder for its or their
own fraud, gross negligence, or willful misconduct).

12.6 DEFAULT; COLLATERAL. Upon the occurrence and continuance of a
Default, Lenders agree to promptly confer in order that Required Lenders or
Lenders, as the case may be, may agree upon a course of action for the
enforcement of the Rights of Lenders; and Administrative Agent shall be entitled
to refrain from taking any action (without incurring any liability to any Person
for so refraining) unless and until Administrative Agent shall have received
instructions from Required Lenders. All rights of action under this Agreement
and under the Notes and all rights to the Collateral, if any, hereunder may be
enforced by Administrative Agent and any suit or proceeding instituted by
Administrative Agent in furtherance of such enforcement shall be brought in its
name as Administrative Agent without the necessity of joining as plaintiffs or
defendants any other Lender, and the recovery of any judgment shall be for the
benefit of Lenders subject to the expenses of Administrative Agent. In actions
with respect to any property of Borrower, Administrative Agent is acting for the
ratable benefit of each Lender. Any and all agreements to subordinate (whether
made heretofore or hereafter) other indebtedness or obligations of Borrower to
the Obligation shall be construed as being for the ratable benefit of each
Lender.

12.7 LIMITATION OF LIABILITY. To the extent permitted by Law,
(a) neither Administrative Agent nor any other Agent (acting in their respective
agent capacities) shall incur any liability to any other Lender, Agent, or
Participant except for acts or omissions resulting from its own fraud, gross
negligence or wilful misconduct, and (b) neither Administrative Agent nor any
other Agent, Lender, or Participant shall incur any liability to any other
Person for any act or omission of any other Lender, Agent, or Participant.

73
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

12.8 RELATIONSHIP OF LENDERS. Nothing herein shall be construed as
creating a partnership or joint venture among Agents and Lenders.

12.9 BENEFITS OF AGREEMENT. Except for the representations and
covenants in SECTION 12.1(c) in favor of Borrower, none of the provisions of
this SECTION 12 shall inure to the benefit of any Company or any other Person
other than Lenders; consequently, no Company or any other Person shall be
entitled to rely upon, or to raise as a defense, in any manner whatsoever, the
failure of any Agent or any Lender to comply with such provisions.

12.10 AGENTS. None of the Lenders identified in this Agreement as
"CO-SYNDICATION AGENTS" or "CO-DOCUMENTATION AGENTS" shall have any rights,
powers, obligations, liabilities, responsibilities, or duties under this
Agreement other than those applicable to all Lenders as such. Without limiting
the foregoing, none of the Lenders so identified as a "CO-SYNDICATION AGENTS" or
"CO-DOCUMENTATION AGENTS" shall have or be deemed to have any fiduciary
relationship with any Lender.

12.11 OBLIGATIONS SEVERAL. The obligations of Lenders hereunder are
several, and each Lender hereunder shall not be responsible for the obligations
of the other Lenders hereunder, nor will the failure of one Lender to perform
any of its obligations hereunder relieve the other Lenders from the performance
of their respective obligations hereunder.

SECTION 13 MISCELLANEOUS.

13.1 HEADINGS. The headings, captions, and arrangements used in any
of the Loan Papers are, unless specified otherwise, for convenience only and
shall not be deemed to limit, amplify, or modify the terms of the Loan Papers,
nor affect the meaning thereof.

13.2 NONBUSINESS DAYS. In any case where any payment or action is
due under any Loan Paper on a day which is not a Business Day, such payment or
action may be delayed until the next-succeeding Business Day, but interest and
fees shall continue to accrue in respect of any payment to which it is
applicable until such payment is in fact made; PROVIDED THAT, if, in the case of
any such payment in respect of a Eurodollar Rate Borrowing, the next-succeeding
Business Day is in the next calendar month, then such payment shall be made on
the next-preceding Business Day.

13.3 NOTICES. Unless specifically otherwise provided, whenever any
Loan Paper requires or permits any consent, approval, notice, request, or demand
from one party to another, such communication must be in writing (which may be
by telex or telecopy) to be effective and shall be deemed to have been given
(a) if by telex, when transmitted to the telex number, if any, for such party,
and the appropriate answer back is received, (b) if by telecopy, when
transmitted to the telecopy number for such party (and all such communications
sent by telecopy shall be confirmed promptly thereafter by personal delivery or
mailing in accordance with the provisions of this section; PROVIDED, THAT any
requirement in this parenthetical shall not affect the date on which such
telecopy shall be deemed to have been delivered), (c) if by mail, on the third
Business Day after it is enclosed in an envelope, properly addressed to such
party, properly stamped, sealed, and deposited in the appropriate official
postal service, or (d) if by any other means, when actually delivered to such

telecopy numbers, if any) for Administrative Agent and each Lender,
Administrative Agent, and other Agents is set forth on SCHEDULE 2.1, and for
Borrower and each Company is the address set forth by Borrower's signature on

13.4 FORM AND NUMBER OF DOCUMENTS. Each agreement, document,
instrument, or other writing to be furnished under any provision of this
Agreement must be in form and substance and in such number of counterparts as
may be reasonably satisfactory to Administrative Agent and its counsel.

13.5 EXCEPTIONS TO COVENANTS. No Company shall take any action or
fail to take any action which is permitted as an exception to any of the
covenants contained in any Loan Paper if such action or omission would result in
the breach of any other covenant contained in any of the Loan Papers.

13.6 SURVIVAL. All covenants, agreements, undertakings,
representations, and warranties made in any of the Loan Papers shall survive all
closings under the Loan Papers and, except as otherwise indicated, shall not be
affected by any investigation made by any party. All rights of, and provisions
relating to, reimbursement and indemnification of Administrative Agent, any
Agent, or any Lender shall survive termination of this Agreement and payment in
full of the Obligation.

13.7 GOVERNING LAW. THE LAWS OF THE STATE OF TEXAS AND OF THE UNITED
STATES OF AMERICA SHALL GOVERN THE RIGHTS AND DUTIES OF THE PARTIES TO THE LOAN
PAPERS AND THE VALIDITY, CONSTRUCTION, ENFORCEMENT, AND INTERPRETATION OF THE

13.8 INVALID PROVISIONS. If any provision in any Loan Paper is held
to be illegal, invalid, or unenforceable, such provision shall be fully
severable; the appropriate Loan Paper shall be construed and enforced as if such
provision had never comprised a part thereof; and the remaining provisions
thereof shall remain in full force and effect and shall not be affected by such
provision or by its severance therefrom. Administrative Agent, Lenders, and
each Company party to such Loan Paper agree to negotiate, in good faith, the
terms of a replacement provision as similar to the severed provision as may be
possible and be legal, valid, and enforceable.

EXECUTED BY ANY COMPANY, ANY GUARANTOR, ANY LENDER, AND/OR ANY AGENT, (TOGETHER
WITH ALL COMMITMENT LETTERS AND FEE LETTERS ONLY AS THEY RELATE TO THE PAYMENT
OF FEES AFTER THE CLOSING DATE) REPRESENT THE FINAL AGREEMENT BETWEEN THE
COMPANIES, THE GUARANTORS, LENDERS, AND AGENTS, AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BY SUCH
PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN SUCH PARTIES.

HERETO, IN EACH CASE FOR ITSELF, ITS SUCCESSORS AND ASSIGNS, HEREBY
(A) IRREVOCABLY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE STATE AND

all disputes that may be filed in any court and that relate to the subject
matter of this transaction, including, without limitation, contract claims,
tort claims, breach of duty claims, and all other common law and statutory
claims. The Companies, Guarantors, and each other party to this Agreement
acknowledge that this waiver is a material inducement to the agreement of
each party hereto to enter into a business relationship, that each has
already relied on this waiver in entering into this Agreement, and each will
continue to rely on each of such waivers in related future dealings. The
Companies, Guarantors, and each other party to this Agreement warrant and
represent that they have reviewed these waivers with their legal counsel, and
that they knowingly and voluntarily agree to each such waiver following
consultation with legal counsel. THE WAIVERS IN THIS SECTION 13.10 ARE
IRREVOCABLE, MEANING THAT THEY MAY NOT BE MODIFIED EITHER ORALLY OR IN
WRITING, AND THESE WAIVERS SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS,
SUPPLEMENTS, AND REPLACEMENTS TO OR OF THIS OR ANY OTHER LOAN PAPER. In the
event of Litigation, this Agreement may be filed as a written consent to a
trial by the court.

13.11 AMENDMENTS, CONSENTS, CONFLICTS, AND WAIVERS.

(a) Except as otherwise specifically provided, (i) this
Agreement may only be amended, modified or waived by an instrument in
writing executed jointly by Borrower and Required Lenders, and, in the
case of any matter affecting Administrative Agent (EXCEPT removal of
Administrative Agent as provided in SECTION 12) by Administrative Agent,
and may only be supplemented by documents delivered or to be delivered
in accordance with the express terms hereof, and (ii) the other Loan
Papers may only be the subject of an amendment, modification, or waiver
if Borrower and Required Lenders, and, in the case of any matter
affecting Administrative Agent (EXCEPT as set forth above),
Administrative Agent, have approved same.

(b) Any amendment to or consent or waiver under this
Agreement or any Loan Paper which purports to accomplish any of the
following must be by an instrument in writing executed by Borrower and
executed (or approved, as the case may be) by each Lender affected
thereby, and, in the case of any matter affecting Administrative Agent,
by Administrative Agent: (i) extends the due date or reduces the amount
of any scheduled payment of the Obligation or any scheduled reduction of
the Revolver Commitment beyond the date specified in the Loan Papers;
(ii) reduces the interest rate or decreases the amount of interest,
fees, or other sums payable to Administrative Agent or Lenders hereunder
(except such reductions as are contemplated by this Agreement); (iii)
change the percentage of the Total Commitment or Revolver Commitment, or
of the Principal Debt which shall be required for the Lenders or any of
them to take any action under this SECTION 13.11 or any other provision
of this Agreement or any Loan Paper; or (iv) except as otherwise
permitted by any Loan Paper, waives compliance with, amends, or releases
(in whole or in part) any material

76
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

Guaranty or releases (in whole or in part) any material Collateral for
the Obligation; or (v) changes this CLAUSE (b) or any other matter
specifically requiring the consent of all Lenders hereunder. Without
the consent of such Lender, no Lender's "COMMITTED SUM" may be
increased.

(c) Any conflict or ambiguity between the terms and
provisions herein and terms and provisions in any other Loan Paper shall
be controlled by the terms and provisions herein.

(d) No course of dealing nor any failure or delay by
Administrative Agent, any Lender, or any of their respective
Representatives with respect to exercising any Right of Administrative
Agent or any Lender hereunder shall operate as a waiver thereof. A
waiver must be in writing and signed by Administrative Agent and
Required Lenders (or by all Lenders, if required hereunder) to be
effective, and such waiver will be effective only in the specific
instance and for the specific purpose for which it is given.

13.12 MULTIPLE COUNTERPARTS. This Agreement may be executed in a
number of identical counterparts, each of which shall be deemed an original for
all purposes and all of which constitute, collectively, one agreement; but, in
making proof of this Agreement, it shall not be necessary to produce or account
for more than one such counterpart. It is not necessary that each Lender
execute the same counterpart so long as identical counterparts are executed by
Borrower, each Lender, and Administrative Agent. This Agreement shall become
effective when counterparts hereof shall have been executed and delivered to
Administrative Agent by each Lender, Administrative Agent, and Borrower, or,
when Administrative Agent shall have received telecopied, telexed, or other
evidence satisfactory to it that such party has executed and is delivering to
Administrative Agent a counterpart hereof.

13.13 SUCCESSORS AND ASSIGNS; ASSIGNMENTS AND PARTICIPATIONS.

(a) This Agreement shall be binding upon, and inure to the
benefit of the parties hereto and their respective successors and
assigns, EXCEPT THAT (i) Borrower may not, directly or indirectly,
assign or transfer, or attempt to assign or transfer, any of its Rights,
duties or obligations under any Loan Papers without the express written
consent of all Lenders, and (ii) EXCEPT as permitted under this Section,
no Lender may transfer, pledge, assign, sell any participation in, or
otherwise encumber its portion of the Obligation.

(b) Each Lender may assign to one or more Eligible Assignees
all or a portion of its Rights and obligations under this Agreement and
the other Loan Papers (including, without limitation, all or a portion
of its Borrowings and its Notes); PROVIDED, HOWEVER, that:

(i) each such assignment shall be to an Eligible
Assignee;

(ii) except in the case of an assignment to another
Lender or an assignment of all of a Lender's Rights and
obligations under this Agreement and the other Loan Papers, any
such partial assignment shall be in an amount at least equal to
$5,000,000 in the aggregate for all Facilities being assigned;
PROVIDED THAT, no partial assignment for any Facility may be
less than $1,000,000.

(iii) each such assignment by a Lender shall be of a
constant, and not varying, percentage of all of its Rights and
obligations under this Agreement and the Notes;

77
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

(iv) the parties to such assignment shall execute and
deliver to the Administrative Agent for its acceptance an
Assignment and Acceptance Agreement in the form of EXHIBIT F
hereto, together with any Notes subject to such assignment and a
processing fee of $3,500, PROVIDED HOWEVER, that with respect to
an assignment to an Affiliate of Lender, the processing fee
shall be $1,500.

Upon execution, delivery, and acceptance of such Assignment and
Acceptance Agreement, the assignee thereunder shall be a party hereto
and, to the extent of such assignment, have the obligations, Rights, and
benefits of a Lender under the Loan Papers and the assigning Lender
shall, to the extent of such assignment, relinquish its rights and be
released from its obligations under the Loan Papers. Upon the
consummation of any assignment pursuant to this Section, but only upon
the request of the assignor or assignee made through Administrative
Agent, Borrower shall issue appropriate Notes to the assignor and the
assignee, reflecting such Assignment and Acceptance. If the assignee is
not incorporated under the laws of the United States of America or a
state thereof, it shall deliver to Borrower and Administrative Agent
certification as to exemption from deduction or withholding of Taxes in
accordance with SECTION 4.6.

(c) Administrative Agent shall maintain at its address
referred to in SECTION 13.3 a copy of each Assignment and Acceptance
Agreement delivered to and accepted by it and a register for the
recordation of the names and addresses of the Lenders and the
Commitment, and principal amount of the Borrowings 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
Borrower, Administrative Agent and the Lenders may treat each Person
whose name is recorded in the Register as a Lender hereunder for all
purposes of the Loan Papers. The Register shall be available for
inspection by Borrower or any Lender at any reasonable time and from
time to time upon reasonable prior notice. Upon the consummation of any
assignment in accordance with this SECTION 13.13, SCHEDULE 2.1 shall
automatically be deemed amended (to the extent required) by
Administrative Agent to reflect the name, address, and respective
Committed Sums under the Facilities of the assignor and assignee.

(d) Upon its receipt of an Assignment and Acceptance
Agreement executed by the parties thereto, together with any Notes
subject to such assignment and payment of the processing fee, the
Administrative Agent shall, if such Assignment and Acceptance has been
completed and is in substantially the form of EXHIBIT F hereto, (i)
accept such Assignment and Acceptance Agreement, (ii) record the
information contained therein in the Register and (iii) give prompt
notice thereof to the parties thereto.

(e) Subject to the provisions of this Section and in
accordance with applicable Law, any Lender may, in the ordinary course
of its business and in accordance with applicable Law, at any time sell
to one or more Persons (each a "PARTICIPANT") participating interests in
its portion of the Obligation. In the event of any such sale to a
Participant, (i) such Lender shall remain a "LENDER" under this
Agreement and the Participant shall not constitute a "LENDER" hereunder,
(ii) such Lender's obligations under this Agreement shall remain
unchanged, (iii) such Lender shall remain solely responsible for the
performance thereof, (iv) such Lender shall remain the holder of its
share of the Principal Debt for all purposes under this Agreement,
(v) Borrower and Administrative Agent shall continue to deal solely and
directly with such Lender in connection with such Lender's Rights and
obligations under the Loan Papers, and (vi) such Lender shall be solely
responsible for any withholding taxes or any filing or reporting
requirements relating to such participation and shall hold Borrower and
Administrative Agent and their respective successors,

78
▇▇▇▇▇▇/SYGNET OPERATING CREDIT AGREEMENT

permitted assigns, officers, directors, employees, agents, and
representatives harmless against the same. Participants shall have
no Rights under the Loan Papers, other than certain voting Rights as
provided below. Subject to the following, each Lender shall be
entitled to obtain (on behalf of its Participants) the benefits of
SECTION 4 with respect to all participations in its part of the
Obligation outstanding from time to time SO LONG AS Borrower shall
not be obligated to pay any amount in excess of the amount that would
be due to such Lender under SECTION 4 calculated as though no
participations have been made. No Lender shall sell any
participating interest under which the Participant shall have any
Rights to approve any amendment, modification, or waiver of any Loan
Paper, except to the extent such amendment, modification, or waiver
extends the due date for payment of any amount in respect of
principal (OTHER THAN mandatory prepayments), interest, or fees due
under the Loan Papers, reduces the interest rate or the amount of
principal or fees applicable to the Obligation (EXCEPT such
reductions as are contemplated by this Agreement), or releases any
material Guaranty or all or any substantial portion of the Collateral
for the Obligation under the Loan Papers (EXCEPT such releases as are
contemplated by this Agreement); PROVIDED THAT, in those cases where
a Participant is entitled to the benefits of SECTION 4 or a Lender
grants Rights to its Participants to approve amendments to or waivers
of the Loan Papers respecting the matters previously described in
this sentence, such Lender must include a voting mechanism in the
relevant participation agreement or agreements, as the case may be,
whereby a majority of such Lender's portion of the Obligation
(whether held by such Lender or Participant) shall control the vote
for all of such Lender's portion of the Obligation. Except in the
case of the sale of a participating interest to another Lender, the
relevant participation agreement shall not permit the Participant to
transfer, pledge, assign, sell participations in, or otherwise
encumber its portion of the Obligation, unless the consent of the
transferring Lender (which consent will not be unreasonably withheld)
has been obtained.

(f) Notwithstanding any other provision set forth in this
Agreement, any Lender may at any time assign and pledge all or any
portion of its Borrowings and its Notes to any Federal Reserve Bank as
collateral security pursuant to Regulation A and any Operating Circular
issued by such Federal Reserve Bank without notice to, or the consent of
Borrower or Administrative Agent and, with the consent of Borrower and
Administrative Agent, after the Closing Date any Term Loan B Lender or
any Term Loan C Lender which is a fund may pledge all or any portion of
its Borrowings and its Notes to its trustee in support of its
obligations to its trustee. No such assignment shall release the
assigning Lender from its obligations hereunder.

(g) Any Lender may furnish any information concerning the
Companies in the possession of such Lender from time to time to Eligible
Assignees and Participants (including prospective Eligible Assignees and
Participants).

13.14 DISCHARGE ONLY UPON PAYMENT IN FULL; REINSTATEMENT IN CERTAIN
CIRCUMSTANCES. The obligations of each Company under the Loan Papers shall
remain in full force and effect until termination of the Total Commitment and
payment in full of the Principal Debt and of all interest, fees, and other
amounts of the Obligation then due and owing, EXCEPT that SECTIONS 4, 11, and
13, and any other provisions under the Loan Papers expressly intended to survive
by the terms hereof or by the terms of the applicable Loan Papers, shall survive
such termination. If at any time any payment of the principal of or interest on
any Note or any other amount payable by any Company under any Loan Paper is
rescinded or must be otherwise restored or returned upon the insolvency,
bankruptcy, or reorganization of such Company or otherwise, the obligations of
each Company under the Loan Papers with respect to such payment shall be
reinstated as though such payment had been due but not made at such time.

FORM OF GUARANTY

THIS GUARANTY is executed as of December , 1998, by
___________________, a _________ corporation [partnership] ("GUARANTOR"), for
the benefit of NATIONSBANK, N.A., a national banking association (in its
capacity as Administrative Agent for Lenders).

WHEREAS, ▇▇▇▇▇▇/Sygnet Operating Company, (including its successor by
merger, Sygnet Wireless, Inc.) ("BORROWER"), NationsBank, N.A., as
Administrative Agent (including its permitted successors and assigns in such
capacity, "ADMINISTRATIVE AGENT"), ▇▇▇▇▇▇ Commercial Paper Inc. and PNC Bank,
National Association, as Co-Syndication Agents (including their permitted
successors and assigns in such capacity, "SYNDICATION AGENT"), Toronto
Dominion (Texas), Inc. and First Union National Bank, as Co-Documentation
Agents (including their permitted successors and assigns in such capacity,
"DOCUMENTATION AGENT"), and Lenders now or hereafter party to the Credit
Agreement (including their respective permitted successors and assigns,
"LENDERS") have entered into a Credit Agreement, dated as of December 23,
1998 (as amended, modified, supplemented, or restated from time to time, the
"CREDIT AGREEMENT");

WHEREAS, provisions of the Credit Agreement permit Guarantor to
directly or indirectly receive proceeds of Borrowings made pursuant thereto;
and

WHEREAS, this Guaranty is integral to the transactions contemplated
by the Loan Papers and is a condition precedent to Lenders' obligations to
extend credit under the Loan Papers.

ACCORDINGLY, for adequate and sufficient consideration, the receipt
and adequacy of which are hereby acknowledged, Guarantor guarantees to
Administrative Agent and Lenders the prompt payment of the Guaranteed Debt
(defined below) as follows:

15. DEFINITIONS. Terms defined in the Credit Agreement have the
same meanings when used, unless otherwise defined, in this Guaranty. As used
in this Guaranty:

BORROWER means Borrower, Borrower as a debtor-in-possession, and any
receiver, trustee, liquidator, conservator, custodian, or similar party
appointed for Borrower or for all or substantially all of Borrower's assets
under any Debtor Relief Law.

CREDIT AGREEMENT is defined in the recitals to this Guaranty.

GUARANTEED DEBT means, collectively, (a) the Obligation and (b) all
present and future costs, attorneys' fees, and expenses reasonably incurred
by Administrative Agent or any Lender to enforce Borrower's, Guarantor's, or
any other obligor's payment of any of the Guaranteed Debt, including, without
limitation (to the extent lawful), all present and future amounts that would
become due but for the operation of Sections 502 or 506 or any other
provision of TITLE 11 of the UNITED STATES CODE and all present and future
accrued and unpaid interest (including, without limitation, all post-maturity
interest and any post-petition interest in any proceeding under Debtor Relief
Laws to which Borrower or Guarantor becomes subject).

GUARANTOR is defined in the preamble to this Guaranty.

EXHIBIT C

LENDER means, individually, or LENDERS means, collectively, on any
date of determination, Administrative Agent, Syndication Agent, Documentation
Agent, and the Lenders.

SUBORDINATED DEBT means all present and future obligations of any
Company to Guarantor, whether those obligations are (a) direct, indirect,
fixed, contingent, liquidated, unliquidated, joint, several, or joint and
several, (b) due or to become due to Guarantor, (c) held by or are to be held
by Guarantor, (d) created directly or acquired by assignment or otherwise, or
(e) evidenced in writing.

16. GUARANTY. This is an absolute, irrevocable, and continuing
guaranty, and the circumstance that at any time or from time to time the
Guaranteed Debt may be paid in full does not affect the obligation of
Guarantor with respect to the Guaranteed Debt incurred after that. This
Guaranty remains in effect until the Guaranteed Debt is fully paid and
performed, all commitments to extend any credit under the Loan Papers have
terminated, and all Financial ▇▇▇▇▇▇ with any Lender have expired. Guarantor
may not rescind or revoke its obligations with respect to the Guaranteed
Debt. Notwithstanding any contrary provision, it is the intention of
Guarantor, Lenders, and Administrative Agent that the amount of the
Guaranteed Debt guaranteed by Guarantor by this Guaranty shall be in, but not
in excess of, the maximum amount permitted by fraudulent conveyance,
fraudulent transfer, or similar Laws applicable to Guarantor. Accordingly,
notwithstanding anything to the contrary contained in this Guaranty or any
other agreement or instrument executed in connection with the payment of any
of the Guaranteed Debt, the amount of the Guaranteed Debt guaranteed by
Guarantor by this Guaranty shall be limited to an aggregate amount equal to
the largest amount that would not render Guarantor's obligations hereunder
subject to avoidance under SECTION 548 of the UNITED STATES BANKRUPTCY CODE
or any comparable provision of any applicable state law.

17. CONSIDERATION. Guarantor represents and warrants that its
liability under this Guaranty may reasonably be expected to directly or
indirectly benefit it.

18. CUMULATIVE RIGHTS. If Guarantor becomes liable for any
indebtedness owing by Borrower to Administrative Agent or any Lender, OTHER
THAN under this Guaranty, that liability may not be in any manner impaired or
affected by this Guaranty. The Rights of Administrative Agent or Lenders
under this Guaranty are cumulative of any and all other Rights that
Administrative Agent or Lenders may ever have against Guarantor. The
exercise by Administrative Agent or Lenders of any Right under this Guaranty
or otherwise does not preclude the concurrent or subsequent exercise of any
other Right.

19. PAYMENT UPON DEMAND. If a Default exists, Guarantor shall,
on demand and without further notice of dishonor and without any notice
having been given to any Guarantor previous to that demand of either the
acceptance by Administrative Agent or Lenders of this Guaranty or the
creation or incurrence of any Guaranteed Debt, pay the amount of the
Guaranteed Debt then due and payable to Administrative Agent and Lenders. It
is not necessary for Administrative Agent or Lenders, in order to enforce
that payment by any Guarantor, first or contemporaneously to institute suit
or exhaust remedies against Borrower or others liable on any Guaranteed Debt
or to enforce Rights against any Collateral securing any Guaranteed Debt.

20. SUBORDINATION. The Subordinated Debt is expressly
subordinated to the full and final payment of the Guaranteed Debt. Guarantor
agrees not to accept any payment of any Subordinated Debt from any Company if
a Default exists. If Guarantor receives any payment of any Subordinated Debt
in violation of the foregoing, Guarantor shall hold that payment in trust for
Administrative Agent and Lenders and promptly turn it over to Administrative
Agent, in the form received (with any necessary endorsements), to be applied
to the Guaranteed Debt.

2 EXHIBIT C

21. SUBROGATION AND CONTRIBUTION. Until payment in full of the
Guaranteed Debt, the termination of the Obligation of Lenders to extend
credit under the Loan Papers, and expiration of all Financial ▇▇▇▇▇▇, (a)
Guarantor may not assert, enforce, or otherwise exercise any Right of
subrogation to any of the Rights or Liens of Administrative Agent or Lenders
or any other beneficiary against Borrower or any other obligor on the
Guaranteed Debt or any collateral or other security or any Right of recourse,
reimbursement, subrogation, contribution, indemnification, or similar Right
against Borrower or any other obligor on any Guaranteed Debt or any guarantor
of it, (b) Guarantor defers all of the foregoing Rights (whether they arise
in equity, under contract, by statute, under common law, or otherwise), and
(c) Guarantor defers the benefit of, and subordinates any Right to
participate in, any Collateral or other security given to Administrative
Agent or Lenders or any other beneficiary to secure payment of any Guaranteed
Debt.

22. NO RELEASE. Guarantor's obligations under this Guaranty may
not be released, diminished, or affected by the occurrence of any one or more
of the following events: (a) Any taking or accepting of any other security
or assurance for any Guaranteed Debt; (b) any release, surrender, exchange,
subordination, impairment, or loss of any Collateral securing any Guaranteed
Debt; (c) any full or partial release of the liability of any other obligor
on the Obligation, EXCEPT for any final release resulting from payment in
full of such Obligation; (d) the modification of, or waiver of compliance
with, any terms of any other Loan Paper; (e) the insolvency, bankruptcy, or
lack of corporate or partnership power of any other obligor at any time
liable for any Guaranteed Debt, whether now existing or occurring in the
future; (f) any renewal, extension, or rearrangement of any Guaranteed Debt
or any adjustment, indulgence, forbearance, or compromise that may be granted
or given by Administrative Agent or any Lender to any other obligor on the
Obligation; (g) any neglect, delay, omission, failure, or refusal of
Administrative Agent or any Lender to take or prosecute any action in
connection with the Guaranteed Debt or to foreclose, take, or prosecute any
action in connection with any Loan Paper; (h) any failure of Administrative
Agent or any Lender to notify Guarantor of any renewal, extension, or
assignment of any Guaranteed Debt, or the release of any security or of any
other action taken or refrained from being taken by Administrative Agent or
any Lender against Borrower or any new agreement between Administrative
Agent, any Lender, and Borrower; IT BEING UNDERSTOOD THAT neither
Administrative Agent nor any Lender is required to give Guarantor any notice
of any kind under any circumstances whatsoever with respect to or in
connection with any Guaranteed Debt, OTHER THAN any notice required to be
given to Guarantor by Law or elsewhere in this Guaranty; (i) the
unenforceability of any Guaranteed Debt against any other obligor or any
security securing same because it exceeds the amount permitted by Law, the
act of creating it is ULTRA ▇▇▇▇▇, the officers creating it exceeded their
authority or violated their fiduciary duties in connection with it, or
otherwise; or (j) any payment of the Obligation to Administrative Agent or
any Lender is held to constitute a preference under any Debtor Relief Law or
for any other reason Administrative Agent or any Lender is required to refund
that payment or make payment to someone else (and in each such instance this
Guaranty will be reinstated in an amount equal to that payment).

23. WAIVERS. To the maximum extent lawful, Guarantor waives all
Rights by which it might be entitled to require suit on an accrued right of
action in respect of any Guaranteed Debt or require suit against Borrower or
others, whether arising under Section 34.02 of the TEXAS BUSINESS AND
COMMERCE CODE, as amended (regarding its Right to require Administrative
Agent or Lenders to ▇▇▇ Borrower on accrued right of action following its
written notice to Administrative Agent or Lenders), Section 17.001 of the
TEXAS CIVIL PRACTICE AND REMEDIES CODE, as amended (allowing suit against it
without suit against Borrower, but precluding entry of judgment against it
before entry of judgment against Borrower), RULE 31 of the TEXAS RULES OF
CIVIL PROCEDURE, as amended (requiring Administrative Agent or Lenders to
join Borrower in any suit against it unless judgment has been previously
entered against Borrower), or otherwise.

3 EXHIBIT C

24. LOAN PAPERS. By execution hereof, Guarantor covenants and
agrees that certain representations, warranties, terms, covenants, and
conditions set forth in the Loan Papers are applicable to Guarantor and shall
be imposed upon Guarantor, and Guarantor reaffirms that each such
representation and warranty is true and correct and covenants and agrees to
promptly and properly perform, observe, and comply with each such term,
covenant, or condition. Moreover, Guarantor acknowledges and agrees that
this Guaranty is subject to the offset provisions of the Loan Papers in favor
of Administrative Agent and Lenders. In the event the Credit Agreement shall
cease to remain in effect for any reason whatsoever during any period when
any part of the Guaranteed Debt remains unpaid, the terms, covenants, and
agreements incorporated herein by reference shall nevertheless continue in
full force and effect as obligations of Guarantor under this Guaranty.

25. RELIANCE AND DUTY TO REMAIN INFORMED. Guarantor confirms
that it has executed and delivered this Guaranty after reviewing the terms
and conditions of the Loan Papers and such other information as it has deemed
appropriate in order to make its own credit analysis and decision to execute
and deliver this Guaranty. Guarantor confirms that it has made its own
independent investigation with respect to Borrower's creditworthiness and is
not executing and delivering this Guaranty in reliance on any representation
or warranty by Administrative Agent or any Lender as to that
creditworthiness. Guarantor expressly assumes all responsibilities to remain
informed of the financial condition of Borrower and any circumstances
affecting Borrower's ability to perform under the Loan Papers to which it is
a party or any collateral securing any Guaranteed Debt.

26. NO REDUCTION. The Guaranteed Debt may not be reduced,
discharged, or released because or by reason of any existing or future
offset, claim, or defense (EXCEPT for the defense of complete and final
payment of the Guaranteed Debt) of Borrower or any other obligor against
Administrative Agent or any Lender or against payment of the Guaranteed Debt,
whether that offset, claim, or defense arises in connection with the
Guaranteed Debt or otherwise. Those claims and defenses include, without
limitation, failure of consideration, breach of warranty, fraud, bankruptcy,
incapacity/infancy, statute of limitations, lender liability, accord and
satisfaction, usury, forged signatures, mistake, impossibility, frustration
of purpose, and unconscionability.

27. COMMUNICATIONS ACT. Notwithstanding any other provision of
this Guaranty, any action taken or proposed to be taken by Administrative
Agent or any Lender under this Guaranty which would affect the operational,
voting, or other control of Borrower or Guarantor, shall be pursuant to
SECTION 310(d) of the COMMUNICATIONS ACT OF 1934 (as amended), applicable
state Law, and the applicable rules and regulations thereunder, and, if and
to the extent required thereby, subject to the prior consent of the FCC or
any applicable PUC.

28. INSOLVENCY OF GUARANTOR. Should Guarantor become insolvent,
or fail to pay Guarantor's debts generally as they become due, or voluntarily
seek, consent to, or acquiesce in, the benefit or benefits of any Debtor
Relief Law (OTHER THAN as a creditor or claimant), or become a party to (or
be made the subject of) any proceeding provided for by any Debtor Relief Law
(OTHER THAN as a creditor or claimant) that could suspend or otherwise
adversely affect the Rights of Administrative Agent or any Lender granted
hereunder, then, in any such event, the Guaranteed Debt shall be, as among
Guarantor, Administrative Agent and Lenders, a fully matured, due, and
payable obligation of Guarantor to Administrative Agent and Lenders (without
regard to whether Borrower is then in default under the Loan Papers or
whether the Obligation, or any part thereof, is then due and owing by
Borrower to any Lender), payable in full by Guarantor to Lenders upon demand,
and the amount thereof so payable shall be the estimated amount owing in
respect of the contingent claim created hereunder.

4 EXHIBIT C

29. LOAN PAPER. This Guaranty is a Loan Paper and is subject to
the applicable provisions of SECTIONS 1 and 13 of the Credit Agreement,
including, without limitation, the provisions relating to GOVERNING LAW,
JURISDICTION, VENUE, SERVICE OF PROCESS, AND WAIVER OF JURY TRIAL, all of
which are incorporated into this Guaranty by reference the same as if set
forth in this Guaranty verbatim.

30. NOTICES. For purposes of SECTIONS 13.3 of the Credit
Agreement, Guarantor's address and telecopy number are as set forth next to
Guarantor's signature on the signature page hereof.

31. AMENDMENTS, ETC. No amendment, waiver, or discharge to or
under this Guaranty is valid unless it is in writing and is signed by the
party against whom it is sought to be enforced and is otherwise in conformity
with the requirements of SECTION 13.11 of the Credit Agreement.

32. ADMINISTRATIVE AGENT AND LENDERS. Administrative Agent is
Administrative Agent for each Lender under the Credit Agreement. All Rights
granted to Administrative Agent under or in connection with this Guaranty are
for each Lender's ratable benefit. Administrative Agent may, without the
joinder of any Lender, exercise any Rights in Administrative Agent's or
Lenders' favor under or in connection with this Guaranty. Administrative
Agent's and each Lender's Rights and obligations VIS-A-VIS each other may be
subject to one or more separate agreements between those parties. However,
Guarantor is not required to inquire about any such agreement or is subject
to any terms of it unless Guarantor specifically joins it. Therefore,
neither Guarantor nor its successors or assigns is entitled to any benefits
or provisions of any such separate agreement or is entitled to rely upon or
raise as a defense any party's failure or refusal to comply with the
provisions of it.

33. PARTIES. This Guaranty benefits Administrative Agent,
Lenders, and their respective successors and assigns and binds Guarantor and
its successors and assigns. Upon appointment of any successor Administrative
Agent under the Credit Agreement, all of the Rights of Administrative Agent
under this Guaranty automatically vests in that new Administrative Agent as
successor Administrative Agent on behalf of Lenders without any further act,
deed, conveyance, or other formality OTHER THAN that appointment. The Rights
of Administrative Agent and Lenders under this Guaranty may be transferred
with any assignment of the Guaranteed Debt. The Credit Agreement contains
provisions governing assignments of the Guaranteed Debt and of Rights and
obligations under this Guaranty.

15. CERTAIN DEFINITIONS. Unless otherwise defined herein, or the
context hereof

EXHIBIT D

otherwise requires, each term defined in either of the Credit Agreement or in
the UCC is used in this Security Agreement with the same meaning; PROVIDED
THAT, if the definition given to such term in the Credit Agreement conflicts
with the definition given to such term in the UCC, the Credit Agreement
definition shall control to the extent legally allowable; and (c) if any
definition given to such term in CHAPTER 9 of the UCC conflicts with the
definition given to such term in any other chapter of the UCC, the CHAPTER 9
definition shall prevail. As used herein, the following terms have the
meanings indicated:

COLLATERAL has the meaning set forth in PARAGRAPH 4 hereof.

FCC LICENSES means all Authorizations, licenses, and permits
issued by the FCC to Debtor.

LENDER means, individually, or LENDERS means, collectively, on
any date of determination, Administrative Agent, Syndication Agent,
Documentation Agent, and Lenders and their permitted successors and
assigns.

OBLIGATION means, collectively, (a) the "OBLIGATION" as defined
in the Credit Agreement, and (b) all indebtedness, liabilities, and
obligations of Debtor arising under this Security Agreement; it being
the intention and contemplation of Debtor and Secured Party that future
advances will be made by Secured Party or one or more Lenders to Debtor
for a variety of purposes, that Debtor may guarantee (or otherwise
become directly or contingently obligated with respect to) the
obligations of others to Secured Party or to one or more Lenders, that
from time to time overdrafts of Debtor's accounts with Secured Party or
with other Lenders may occur, and that Secured Party or one or more
Lenders may from time to time acquire from others obligations of Debtor
to such others, and that payment and repayment of all of the foregoing
are intended to and shall be part of the Obligation secured hereby. The
Obligation shall include, without limitation, future, AS WELL AS
existing, advances, indebtedness, liabilities, and obligations owed by
Debtor to Secured Party or to any Lender arising under the Loan Papers
or otherwise.

OBLIGOR means any Person obligated with respect to any of the
Collateral, whether as an account debtor, obligor on an instrument,
issuer of securities, or otherwise.

PARTNERSHIP means any partnership issuing a Partnership
Interest.

PLEDGED SECURITIES means, collectively, the Pledged Shares, the
Partnership Interests (whether or not a security), and any other
Collateral constituting securities.

SECURITY INTEREST means the security interest granted and the
pledge and assignment made under PARAGRAPH 3 hereof.

UCC means the Uniform Commercial Code as enacted in the State of
Texas or other applicable jurisdiction, as amended at the time in
question.

16. SECURITY INTEREST. In order to secure the full and complete
payment and performance of the Obligation when due, Debtor hereby grants to
Secured Party a Security Interest in all of Debtor's Rights, titles, and
interests in and to the Collateral and pledges, collaterally transfers, and
assigns the Collateral to Secured Party, all upon and subject to the terms
and conditions of this Security Agreement. Such Security Interest is granted
and pledge and assignment are made as security only and shall not subject
Secured Party to, or transfer or in any way affect or modify, any obligation
of Debtor with respect to any of the Collateral or any transaction involving
or giving rise thereto. The grant contained herein is intended to

2 EXHIBIT D

confer upon Secured Party all Rights that a secured creditor may obtain and
that may be granted in the FCC Licenses under applicable Law as from time to
time in effect. If the Law is subsequently changed or clarified, or if the
FCC's interpretation of existing Law is changed, to permit or further permit
the granting of such security interests in FCC Licenses, then Debtor's FCC
Licenses, whether now held or hereinafter acquired, shall automatically
become subject to the Secured Party's Security Interest to the maximum extent
permitted by the Law as then in effect. In the meantime, the value of the
Systems' and Debtor's cellular telephone communication businesses as a going
concern depends upon the holder of Debtor's FCC Licenses also being the owner
of the assets used or useful in the operation of the Systems and, if
ownership of those assets is separated from the FCC Licenses, the FCC might,
under currently applicable Law, cancel the FCC Licenses. Accordingly, Debtor
and Secured Party, in recognition of the unique nature of the FCC Licenses
and the fact that the separation of the FCC Licenses from Debtor's operating
assets may prevent Lenders from adequately realizing the value of their
Security Interests, have provided in PARAGRAPH 9(b) hereof for the
appointment of a receiver upon a Default or Potential Default and for the
assignment of the FCC Licenses in the event of the foreclosure hereunder,
with the specific intention in each case that the physical assets used in
connection with the Systems not be separated from the FCC Licenses. If the
grant, pledge, or collateral transfer or assignment of any specific item of
the Collateral is expressly prohibited by any contract, then the Security
Interest created hereby nonetheless remains effective to the extent allowed
by UCC Section 9.318 or other applicable Law, but is otherwise limited by
that prohibition.

[The description of the Collateral contained in this PARAGRAPH 4 shall not be
deemed to permit any action prohibited by this Security Agreement or by the
terms incorporated in this Security Agreement. Furthermore, notwithstanding any
contrary provision, Debtor agrees that, if, but for the application of this
paragraph, granting a Security Interest in the Collateral would constitute a
fraudulent conveyance under 11 U.S.C. Section 548 or a fraudulent conveyance or
transfer under any state fraudulent conveyance, fraudulent transfer, or similar
Law in effect from time to time (each a "FRAUDULENT CONVEYANCE"), then the
Security Interest remains enforceable to the maximum extent possible without
causing such Security Interest to be a fraudulent conveyance, and this Security
Agreement is automatically amended to carry out the intent of this paragraph.]
[BRACKETED LANGUAGE TO BE INCLUDE ALL SECURITY AGREEMENTS OTHER THAN THE
SECURITY AGREEMENT FOR BORROWER.]

18. REPRESENTATIONS AND WARRANTIES. Debtor represents and
warrants to Secured Party that:

(a) CREDIT AGREEMENT. Certain representations and
warranties in the Credit Agreement are applicable to it or its assets or
operations, and each such representation and warranty is true and
correct.

(b) BINDING OBLIGATION. This Security Agreement creates a
legal, valid, and binding Lien in and to the Collateral in favor of
Secured Party and enforceable against Debtor. For Collateral in which
the Security Interest may be perfected by the filing of Financing
Statements, once those Financing Statements have been properly filed in
the jurisdictions described on ANNEX A hereto, the Security Interest in
that Collateral will be fully perfected. Once perfected and, in the
case of investment property or instruments, upon possession or "CONTROL"
(within the meaning of SECTIONS 8-106 and 9-115 of the UCC) by Secured
Party, the Security Interest will constitute a first-priority Lien on
the Collateral, subject only to Permitted Liens. The creation of the
Security Interest does not require the consent of any Person that has
not been obtained.

(c) LOCATION. Debtor's place of business and chief
executive office is where Debtor is entitled to receive notices
hereunder; the present and foreseeable location of Debtor's books and
records concerning any of the Collateral that is accounts is as set
forth on ANNEX A hereto, and the location of all other Collateral,
including, without limitation, Debtor's inventory and equipment, is as
set forth on ANNEX A hereto (but the failure of such description to be
accurate or complete shall not impair the Security Interest in such
Collateral); and, EXCEPT as noted on ANNEX A hereto, all such books,
records, and Collateral are in Debtor's possession.

(d) FIXTURES. The Collateral that is or may be fixtures is
located on or affixed to the real property described on ANNEX A hereto
(but the failure of such description to be accurate or complete shall
not impair the Security Interest in such Collateral).

5 EXHIBIT D

(e) SECURITIES. All Collateral that is Pledged Securities
is duly authorized, validly issued, fully paid, and non-assessable, and
the transfer thereof is not subject to any restrictions, other than
restrictions imposed by applicable securities and corporate Laws. The
Pledged Shares issued by the Subsidiaries to Debtor constitute 100% of
the issued and outstanding common stock or other equity interests of
such Subsidiaries. Debtor has good title to the securities, free and
clear of all Liens and encumbrances thereon (EXCEPT for the Security
Interest created hereby), and has delivered to Secured Party all stock
certificates, promissory notes, bonds, debentures, or other instruments
or documents representing or evidencing the securities, TOGETHER WITH
corresponding assignment or transfer powers duly executed in blank by
Debtor, and such powers have been duly and validly executed and are
binding and enforceable against Debtor in accordance with their terms;
and the pledge of the securities in accordance with the terms hereof
creates a valid and perfected first priority security interest in the
securities securing payment of the Obligation.

(f) PARTNERSHIPS AND PARTNERSHIP INTERESTS. Each
Partnership issuing a Partnership Interest, including, without
limitation, any Cellular Partnership, is duly organized, currently
existing, and in good standing under all applicable Laws; there have
been no amendments, modifications, or supplements to any agreement or
certificate creating any Partnership or any material contract relating
to the Partnerships, of which Secured Party has not been advised in
writing; no default or potential default has occurred under the terms of
any material contract relating to any Partnership; and no approval or
consent of the partners of any Partnership is required as a condition to
the validity and enforceability of the Security Interest created hereby
or the consummation of the transactions contemplated hereby which has
not been duly obtained by Debtor. Debtor has good title to the
Partnership Interests free and clear of all Liens and encumbrances
(EXCEPT for the Security Interest granted hereby). The Partnership
Interests are validly issued, fully paid, and nonassessable and are not
subject to statutory, contractual, or other restrictions governing their
transfer, ownership, or control, EXCEPT as set forth in the partnership
agreements of the Cellular Partnerships or applicable securities Laws.

(g) GOVERNMENTAL AUTHORITY. No authorization, approval, or
other action by, and no notice to or filing with, any Governmental
Authority is required either (i) for the pledge by Debtor of the Pledged
Securities pursuant to this Security Agreement or for the execution,
delivery, or performance of this Security Agreement by Debtor, or
(ii) for the exercise by Secured Party of the voting or other Rights
provided for in this Security Agreement or the remedies in respect of
the Collateral pursuant to this Security Agreement (EXCEPT as may be
required in connection with the disposition of the Pledged Securities by
Laws affecting the offering and sale of securities generally and in
connection with the transfer of control of FCC Licenses).

(h) ACCOUNTS. All Collateral that is accounts, contract
Rights, chattel paper, instruments, or general intangibles is free from
any claim for credit, deduction, or allowance of an Obligor and free
from any defense, dispute, setoff, or counterclaim, and there is no
extension or indulgence with respect thereto.

(i) INSTRUMENTS, CHATTEL PAPER, COLLATERAL NOTES, AND
COLLATERAL NOTE SECURITY. All instruments and chattel paper,
including, without limitation, the Collateral Notes, have been delivered
to Secured Party, TOGETHER WITH corresponding endorsements duly executed
by Debtor in favor of Secured Party, and such endorsements have been
duly and validly executed and are binding and enforceable against Debtor
in accordance with their terms. Each Collateral Note and the documents
evidencing the Collateral Note Security are in full force and effect;
there have been no renewals or extensions of, or amendments,
modifications, or supplements to, any thereof about which the Secured

6 EXHIBIT D

Party has not been advised in writing; and no default or potential
default has occurred and is continuing under any such Collateral Note or
documents evidencing the Collateral Note Security, EXCEPT as disclosed
on ANNEX C hereto.

(j) ASSIGNED LEASES. All Collateral that is an Assigned
Lease is in full force and effect; Debtor is in possession of the
property covered by each such Assigned Lease; and no default or
potential default exists under any such Assigned Lease.

(k) MAINTENANCE OF COLLATERAL. All tangible Collateral is
in good repair and condition, ordinary wear and tear excepted, and none
thereof is a fixture EXCEPT as specifically referred to herein in
PARAGRAPH 5(d) hereof.

(l) LIENS. Debtor owns all presently existing Collateral,
and will acquire all hereafter-acquired Collateral, free and clear of
all Liens, EXCEPT Permitted Liens.

(m) DEPOSIT ACCOUNTS. With respect to the Deposit Accounts,
(i) Debtor maintains each such Deposit Account with the banks listed on
ANNEX D hereto, (ii) Debtor shall use its best efforts to, within thirty
(30) days of the Closing Date, cause each such bank to acknowledge to
Secured Party that such Deposit Accounts are subject to the Security
Interest and Liens herein created, (iii) Debtor has the legal right to
pledge and assign to Secured Party the funds deposited and to be
deposited in the Deposit Accounts; and (iv) the Deposit Accounts listed
on ANNEX D represent all material bank accounts of Debtor, including
without limitation, all material operating accounts of Debtor, and all
certificates of deposit or other deposit instruments of Debtor.

The foregoing representations and warranties will be true and correct in all
respects with respect to any additional Collateral or additional specific
descriptions of certain Collateral delivered to Secured Party in the future
by Debtor.

The failure of any of these representations or warranties to be
accurate and complete does not impair the Security Interest in any Collateral.

19. COVENANTS. So long as Lenders are committed to extend credit
to Debtor under the Credit Agreement and until the Obligation is paid and
performed in full, Debtor covenants and agrees with Secured Party that Debtor
will:

(a) CREDIT AGREEMENT. (i) Comply with, perform, and be
bound by all covenants and agreements in the Credit Agreement that are
applicable to it, its assets, or its operations, each of which is hereby
ratified and confirmed (INCLUDING, WITHOUT LIMITATION, THE
INDEMNIFICATION AND RELATED PROVISIONS IN SECTIONS 11.12 OF THE CREDIT
AGREEMENT); AND (ii) CONSENT TO AND APPROVE THE VENUE, SERVICE OF
PROCESS, AND WAIVER OF JURY TRIAL PROVISIONS OF SECTIONS 13.10 OF THE
CREDIT AGREEMENT.

(b) RECORD OF COLLATERAL. Maintain, at the place where
Debtor is entitled to receive notices under the Loan Papers, a current
record of where all Collateral is located, permit representatives of
Secured Party at any time during normal business hours to inspect and
make abstracts from such records, and furnish to Secured Party, at such
intervals as Secured Party may request, such documents, lists,
descriptions, certificates, and other information as may be necessary

7 EXHIBIT D

or proper to keep Secured Party informed with respect to the identity,
location, status, condition, and value of the Collateral.

(c) PERFORM OBLIGATIONS. Fully perform all of Debtor's
duties under and in connection with each transaction to which the
Collateral, or any part thereof, relates, so that the amounts thereof
shall actually become payable in their entirety to Secured Party.

(d) NOTICES. (i) Promptly notify Secured Party of (A) any
change in any fact or circumstances represented or warranted by Debtor
with respect to any of the Collateral or Obligation, and (B) any claim,
action, or proceeding affecting title to all or any of the Collateral or
the Security Interest and, at the request of Secured Party, appear in
and defend, at Debtor's expense, any such action or proceeding; and
(ii) give Secured Party thirty (30) days written notice before any
proposed (A) relocation of its principal place of business or chief
executive office, (B) change of its name, identity, or corporate
structure, (C) relocation of the place where its books and records
concerning its accounts are kept, and (D) relocation of any Collateral
(OTHER THAN delivery of inventory in the ordinary course of business to
third party contractors for processing and sales of inventory in the
ordinary course of business or as permitted by the Credit Agreement) to
a location not described on the attached ANNEX A. Prior to making any
of the changes contemplated in CLAUSE (ii) preceding, Debtor shall
execute and deliver all such additional documents and perform all
additional acts as Secured Party, in its sole discretion, may request in
order to continue or maintain the existence and priority of the Security
Interests in all of the Collateral.

(e) COLLATERAL IN TRUST. Hold in trust (and not commingle
with other assets of Debtor) for Secured Party all Collateral that is
chattel paper, instruments, Collateral Notes, Pledged Securities, or
documents at any time received by Debtor, and promptly deliver same to
Secured Party, unless Secured Party at its option (which may be
evidenced only by a writing signed by Secured Party stating that Secured
Party elects to permit Debtor to so retain) permits Debtor to retain the
same, but any chattel paper, instruments, Collateral Notes, or documents
so retained shall be marked to state that they are assigned to Secured
Party; each such instrument shall be endorsed to the order of Secured
Party (but the failure of same to be so marked or endorsed shall not
impair the Security Interest thereon).

(f) FURTHER ASSURANCES. At Debtor's expense and Secured
Party's request, before or after a Default or Potential Default,
(i) file or cause to be filed such applications and take such other
actions as Secured Party may request to obtain the consent or approval
of any Governmental Authority to Secured Party's Rights hereunder,
including, without limitation, the Right to sell all the Collateral upon
a Default or Potential Default without additional consent or approval
from such Governmental Authority (and, because Debtor agrees that
Secured Party's remedies at Law for failure of Debtor to comply with
this provision would be inadequate and that such failure would not be
adequately compensable in damages, Debtor agrees that its covenants in
this provision may be specifically enforced); (ii) from time to time
promptly execute and deliver to Secured Party all such other
assignments, certificates, supplemental documents, and financing
statements, and do all other acts or things as Secured Party may
reasonably request in order to more fully create, evidence, perfect,
continue, and preserve the priority of the Security Interest; and
(iii) pay all filing fees in connection with any financing,
continuation, or termination statement or other instrument with respect
to the Security Interests, including, without limitation, any filing fee
required in connection with any procedure hereafter developed for the
recordation or registration of Liens or security interests in FCC
Licenses.

8 EXHIBIT D

(g) FIXTURES. For any Collateral that is a fixture or an
accession which has been attached to real estate or other goods prior to
the perfection of the Security Interest, furnish Secured Party, upon
demand, a disclaimer of interest in each such fixture or accession and a
consent in writing to the Security Interest of Secured Party therein,
signed by all Persons having any interest in such fixture or accession
by virtue of any interest in the real estate or other goods to which
such fixture or accession has been attached.

(h) ESTOPPEL AND OTHER AGREEMENTS AND MATTERS. Either
(unless waived by Secured Party in its sole judgment without requiring
approval of any other Lender) (i) use commercially reasonable efforts to
cause the landlord or lessor for each location where any of its
inventory or equipment is maintained to execute and deliver to Secured
Party an estoppel and subordination agreement in such form as may be
reasonably acceptable to Secured Party and its counsel, OR (ii) deliver
to Secured Party a legal opinion or other evidence (in each case that is
reasonably satisfactory to Secured Party and it counsel) that neither
the applicable lease nor the Laws of the jurisdiction in which that
location is situated provide for contractual, common law, or statutory
landlord's Liens that is senior to or PARI PASSU with the Security
Interest.

(i) CERTIFICATES OF TITLE. Upon the request of Secured
Party, if certificates of title are issued or outstanding with respect
to any of the Vehicles or other Collateral, cause the Security Interest
to be properly noted thereon.

(j) IMPAIRMENT OF COLLATERAL. Not use any of the
Collateral, or permit the same to be used, for any unlawful purpose, in
any manner that is reasonably likely to adversely impair the value or
usefulness of the Collateral, or in any manner inconsistent with the
provisions or requirements of any policy of insurance thereon nor affix
or install any accessories, equipment, or device on the Collateral or on
any component thereof if such addition will impair the original intended
function or use of the Collateral or such component.

(k) MODIFICATIONS TO AGREEMENTS. Not modify or substitute,
or permit the modification or substitution of, any Collateral Note or
any document evidencing the Collateral Note Security or contract to
which any of the Collateral which is accounts relates, nor extend or
grant indulgences regarding any account which is Collateral, other than
such modifications or indulgences as are reasonable and customary in the
industry in which Debtor is engaged.

(l) SECURITIES. Not sell, exchange, or otherwise dispose
of, or grant any option, warrant, or other Right with respect to, any of
the Pledged Shares; cause each Subsidiary not to issue any stock or
other securities in addition to or in substitution for the Pledged
Shares issued by the Subsidiaries, EXCEPT to Debtor; pledge hereunder,
immediately upon Debtor's acquisition (directly or indirectly) thereof,
any and all additional shares of stock or other securities of the
Subsidiaries or any other issuer of Securities issued to Debtor; and
take any action necessary, required, or requested by Secured Party to
allow Secured Party to fully enforce its Security Interest in the
Pledged Shares, including, without limitation, the filing of any claims
with any court, liquidator, trustee, custodian, receiver, or other like
person or party.

(m) PARTNERSHIPS AND PARTNERSHIP INTERESTS. (i) Promptly
perform, observe, and otherwise comply with each and every covenant,
agreement, requirement, and condition set forth in the contracts and
agreements creating or relating to any Partnership; (ii) do or cause to
be done all things necessary or appropriate to keep the Partnerships in
full force and effect and the Rights of Debtor and Secured Party
thereunder unimpaired; (iii) not consent to any Partnership selling,
leasing, or

9 EXHIBIT D

disposing of substantially all of its assets in a single transaction
or a series of transactions; (iv) notify Secured Party of the occurrence
of any default under any contract or agreement creating or relating to
the Partnerships; and not consent to the amendment, modification,
surrender, impairment, forfeiture, cancellation, dissolution, or
termination of any Partnership, or material agreement relating
thereto; (v) not transfer, sell, or assign any of the Partnership
Interests or any part thereof; (vi) cause each Partnership to refrain
from granting any partnership interests in addition to or in
substitution for the Partnership Interests granted by the Partnerships,
EXCEPT to Debtor; (vii) pledge hereunder, immediately upon Debtor's
acquisition (directly or indirectly) thereof, any and all additional
Partnership Interests of any Partnership granted to Debtor; and
(viii) take any action necessary, required, or requested by Secured
Party to allow Secured Party to fully enforce its Security Interest in
the Partnership Interests, including, without limitation, the filing of
any claims with any court, liquidator, trustee, custodian, receiver, or
other like person or party.

described on ANNEX D or such additional depository banks as have
complied with ITEM (iv) hereof; (ii) within thirty (30) days of the
Closing Date, deliver to each depository bank a letter in the form of
ANNEX E hereto with respect to Secured Party's rights in such Deposit
Account and use its best efforts to obtain the execution of such letter

or instruments, if any, now or hereafter representing or evidencing the
Deposit Accounts, accompanied by duly executed instruments of transfer

Secured Party; and (iv) notify Secured Party prior to establishing any
additional Deposit Accounts and, at the request of Secured Party, obtain
from such depository bank an executed letter substantially in the form
of ANNEX E and deliver the same to Secured Party.

20. DEFAULT; REMEDIES. If a Default or a Potential Default
exists, Secured Party may, at its election (but subject to the terms and
conditions of the Credit Agreement), exercise any and all Rights available to
a secured party under the UCC, in addition to any and all other Rights
afforded by the Loan Papers, at Law, in equity, or otherwise, including,
without limitation, (a) requiring Debtor to assemble all or part of the
Collateral and make it available to Secured Party at a place to be designated
by Secured Party which is reasonably convenient to Debtor and Secured Party,
(b) surrendering any policies of insurance on all or part of the Collateral
and receiving and applying the unearned premiums as a credit on the
Obligation, (c) applying by appropriate judicial proceedings for appointment
of a receiver for all or part of the Collateral (and Debtor hereby consents
to any such appointment), and (d) applying to the Obligation any cash held by
Secured Party under this Security Agreement, including, without limitation,
any cash in the Cash Collateral Account (defined in SECTION 8(g)).
Notwithstanding the foregoing, Secured Party will not exercise any remedies
against the assets of Debtor unless it has given at least ten days written
notification to Debtor and to the FCC, to the extent such notice is required
under 47 C.F.R. 22.937(f).

(a) NOTICE. Reasonable notification of the time and place
of any public sale of the Collateral, or reasonable notification of the
time after which any private sale or other intended disposition of the
Collateral is to be made, shall be sent to Debtor and to any other
Person entitled to notice under the UCC; PROVIDED THAT, if any of the
Collateral threatens to decline speedily in value or is of the type
customarily sold on a recognized market, Secured Party may sell or
otherwise dispose of the Collateral without notification, advertisement,
or other notice of any kind. It is agreed that notice sent or given not
less than ten Business Days prior to the taking of the action to which
the notice relates is reasonable notification and notice for the
purposes of this subparagraph.

(b) SALES OF PLEDGED SECURITIES.

10 EXHIBIT D

(i) Debtor agrees that, because of the Securities
Act of 1933, as amended, or the rules and regulations
promulgated thereunder (collectively, the "SECURITIES ACT"), or
any other Laws or regulations, and for other reasons, there may
be legal or practical restrictions or limitations affecting
Secured Party in any attempts to dispose of certain portions of
the Pledged Securities and for the enforcement of its Rights.
For these reasons, Secured Party is hereby authorized by Debtor,
but not obligated, upon the occurrence and during the
continuation of a Default or Potential Default, to sell all or
any part of the Pledged Securities at private sale, subject to
investment letter or in any other manner which will not require
the Pledged Securities, or any part thereof, to be registered in
accordance with the Securities Act or any other Laws or
regulations, at a reasonable price at such private sale or other
distribution in the manner mentioned above. Debtor understands
that Secured Party may in its discretion approach a limited
number of potential purchasers and that a sale under such
circumstances may yield a lower price for the Pledged
Securities, or any part thereof, than would otherwise be
obtainable if such Collateral were either afforded to a larger
number or potential purchasers, registered under the Securities
Act, or sold in the open market. Debtor agrees that any such
private sale made under this PARAGRAPH 7(b) shall be deemed to
have been made in a commercially reasonable manner, and that
Secured Party has no obligation to delay the sale of any Pledged
Securities to permit the issuer thereof to register it for
public sale under any applicable federal or state securities
Laws.

(ii) Secured Party is authorized, in connection with
any such sale, (A) to restrict the prospective bidders on or
purchasers of any of the Pledged Securities to a limited number
of sophisticated investors who will represent and agree that
they are purchasing for their own account for investment and not
with a view to the distribution or sale of any of such Pledged
Securities, and (B) to impose such other limitations or
conditions in connection with any such sale as Secured Party
reasonably deems necessary in order to comply with applicable
Law. Debtor covenants and agrees that it will execute and
deliver such documents and take such other action as Secured
Party reasonably deems necessary in order that any such sale may
be made in compliance with applicable Law. Upon any such sale
Secured Party shall have the right to deliver, assign, and
transfer to the purchaser thereof the Pledged Securities so
sold. Each purchaser at any such sale shall hold the Pledged
Securities so sold absolutely free from any claim or Right of
Debtor of whatsoever kind, including any equity or right of
redemption of Debtor. Debtor, to the extent permitted by
applicable Law, hereby specifically waives all rights of
redemption, stay, or appraisal which it has or may have under
any Law now existing or hereafter enacted.

(iii) Debtor agrees that five days' written notice
from Secured Party to Debtor of Secured Party's intention to
make any such public or private sale or sale at a broker's board
or on a securities exchange shall constitute "REASONABLE
NOTIFICATION" within the meaning of SECTION 9-504(c) of the UCC.
Such notice shall (A) in case of a public sale, state the time
and place fixed for such sale, (B) in case of sale at a broker's
board or on a securities exchange, state the board or exchange
at which such a sale is to be made and the day on which the
Pledged Securities, or the portion thereof so being sold, will
first be offered to sale at such board or exchange, and (C) in
the case of a private sale, state the day after which such sale
may be consummated. Any such public sale shall be held at such
time or times within ordinary business hours and at such place
or places as Secured Party may fix in the notice of such sale.
At any such sale, the Pledged Securities may be sold in one lot
as an entirety or in separate parcels, as Secured Party may
reasonably determine. Secured

11 EXHIBIT D

Party shall not be obligated to make any such sale pursuant to
any such notice. Secured Party may, without notice or
publication, adjourn any public or private sale or cause the
same to be adjourned from time to time by announcement at the
time and place fixed for the sale, and such sale may be made at
any time or place to which the same may be so adjourned.

(iv) In case of any sale of all or any part of the
Pledged Securities on credit or for future delivery, the Pledged
Securities so sold may be retained by Secured Party until the
selling price is paid by the purchaser thereof, but Secured
Party shall not incur any liability in case of the failure of
such purchaser to take up and pay for the Pledged Securities so
sold and in case of any such failure, such Pledged Securities
may again be sold upon like notice. Secured Party, instead of
exercising the power of sale herein conferred upon it, may
proceed by a suit or suits at law or in equity to foreclose the
Security Interests and sell the Pledged Securities, or any
portion thereof, under a judgment or decree of a court or courts
of competent jurisdiction.

(v) Without limiting the foregoing, or imposing upon
Secured Party any obligations or duties not required by
applicable Law, Debtor acknowledges and agrees that, in
foreclosing upon any of the Pledged Securities, or exercising
any other Rights or remedies provided Secured Party hereunder or
under applicable Law, Secured Party may, but shall not be
required to, (A) qualify or restrict prospective purchasers of
the Pledged Securities by requiring evidence of sophistication
or creditworthiness, and requiring the execution and delivery of
confidentiality agreements or other documents and agreements as
a condition to such prospective purchasers' receipt of
information regarding the Pledged Securities or participation in
any public or private foreclosure sale process, (B) provide to
prospective purchasers business and financial information
regarding the Companies available in the files of Secured Party
at the time of commencing the foreclosure process, without the
requirement that Secured Party obtain, or seek to obtain, any
updated business or financial information or verify, or certify
to prospective purchasers, the accuracy of any such business or
financial information, or (C) offer for sale and sell the
Pledged Securities with, or without, first employing an
appraiser, investment banker, or broker with respect to the
evaluation of the Pledged Securities, the solicitation of
purchasers for Pledged Securities, or the manner of sale of
Pledged Securities.

(c) APPLICATION OF PROCEEDS. Secured Party shall apply the
proceeds of any sale or other disposition of the Collateral under this
PARAGRAPH 7 in the following order: FIRST, to the payment of all
expenses incurred in retaking, holding, and preparing any of the
Collateral for sale(s) or other disposition, in arranging for such
sale(s) or other disposition, and in actually selling or disposing of
the same (all of which are part of the Obligation); SECOND, toward
repayment of amounts expended by Secured Party under PARAGRAPH 8; THIRD,
toward payment of the balance of the Obligation in the order and manner
specified in the Credit Agreement. Any surplus remaining shall be
delivered to Debtor or as a court of competent jurisdiction may direct.
If the proceeds are insufficient to pay the Obligation in full, Debtor
shall remain liable for any deficiency.

21. OTHER RIGHTS OF SECURED PARTY.

(a) PERFORMANCE. If Debtor fails to keep the Collateral in
good repair, working order, and condition, as required in this Security
Agreement, or fails to pay when due all Taxes on any of the Collateral
in the manner required by the Loan Papers, or fails to preserve the
priority of the Security Interest in any of the Collateral, or fails to
keep the Collateral insured as required by this

12 EXHIBIT D

Security Agreement, or otherwise fails to perform any of its obligations
under the Loan Papers with respect to the Collateral, then Secured Party
may, at its option, but without being required to do so, make such
repairs, pay such Taxes, prosecute or defend any suits in relation to
the Collateral, or insure and keep insured the Collateral in any amount
deemed appropriate by Secured Party, or take all other action which
Debtor is required, but has failed or refused, to take under the Loan
Papers. Any sum which may be expended or paid by Secured Party under
this subparagraph (including, without limitation, court costs and
attorneys' fees) shall bear interest from the dates of expenditure or
payment at the Default Rate until paid and, TOGETHER WITH such interest,
shall be payable by Debtor to Secured Party upon demand and shall be
part of the Obligation.

(b) COLLECTION. If a Default or Potential Default exists
and upon notice from Secured Party, each Obligor with respect to any
payments on any of the Collateral (including, without limitation,
dividends and other distributions with respect to securities, payments
on Collateral Notes, insurance proceeds payable by reason of loss or
damage to any of the Collateral, or Deposit Accounts) is hereby
authorized and directed by Debtor to make payment directly to Secured
Party, regardless of whether Debtor was previously making collections
thereon. Subject to PARAGRAPH 8(e) hereof, until such notice is given,
Debtor is authorized to retain and expend all payments made on
Collateral. If a Default or Potential Default exists, Secured Party
shall have the Right in its own name or in the name of Debtor to
compromise or extend time of payment with respect to all or any portion
of the Collateral for such amounts and upon such terms as Secured Party
may determine; to demand, collect, receive, receipt for, ▇▇▇ for,
compound, and give acquittances for any and all amounts due or to become
due with respect to Collateral; to take control of cash and other
proceeds of any Collateral; to endorse the name of Debtor on any notes,
acceptances, checks, drafts, money orders, or other evidences of payment
on Collateral that may come into the possession of Secured Party; to
sign the name of Debtor on any invoice or ▇▇▇▇ of lading relating to any
Collateral, on any drafts against Obligors or other Persons making
payment with respect to Collateral, on assignments and verifications of
accounts or other Collateral and on notices to Obligors making payment
with respect to Collateral; to send requests for verification of
obligations to any Obligor; and to do all other acts and things
necessary to carry out the intent of this Security Agreement. If a
Default or Potential Default exists and any Obligor fails or refuses to
make payment on any Collateral when due, Secured Party is authorized, in
its sole discretion, either in its own name or in the name of Debtor, to
take such action as Secured Party shall deem appropriate for the
collection of any amounts owed with respect to Collateral or upon which
a delinquency exists. Regardless of any other provision hereof,
however, Secured Party shall never be liable for its failure to collect,
or for its failure to exercise diligence in the collection of, any
amounts owed with respect to Collateral, nor shall it be under any duty
whatsoever to anyone EXCEPT Debtor to account for funds that it shall
actually receive hereunder. Without limiting the generality of the
foregoing, Secured Party shall have no responsibility for ascertaining
any maturities, calls, conversions, exchanges, offers, tenders, or
similar matters relating to any Collateral, or for informing Debtor with
respect to any of such matters (irrespective of whether Secured Party
actually has, or may be deemed to have, knowledge thereof). The receipt
of Secured Party to any Obligor shall be a full and complete release,
discharge, and acquittance to such Obligor, to the extent of any amount
so paid to Secured Party.

(c) RECORD OWNERSHIP OF SECURITIES. If a Default or
Potential Default exists, Secured Party at any time may have any
Collateral that is Pledged Securities and that is in the possession of
Secured Party, or its nominee or nominees, registered in its name, or in
the name of its nominee or nominees, as pledgee; and, as to any Pledged
Securities so registered, Debtor shall execute and deliver (or cause to
be executed and delivered) to Secured Party all such proxies, powers of
attorney, dividend coupons or orders, and other documents as Secured
Party may reasonably request for the purpose of enabling Secured Party
to exercise the voting Rights and powers which it is entitled to

13 EXHIBIT D

exercise under this Security Agreement or to receive the dividends and
other payments in respect of such Collateral that is Pledged Securities
which it is authorized to receive and retain under this Security
Agreement.

(d) VOTING OF SECURITIES. As long as neither a Default nor
Potential Default exists, Debtor is entitled to exercise all voting
Rights pertaining to any Collateral that is Pledged Securities. If a
Default or Potential Default exists and if Secured Party elects to
exercise such Right, the Right to vote any Collateral that is Pledged
Securities shall be vested exclusively in Secured Party. To this end,
Debtor hereby irrevocably constitutes and appoints Secured Party the
proxy and attorney-in-fact of Debtor, with full power of substitution,
to vote, and to act with respect to, any and all Collateral that is
Pledged Securities standing in the name of Debtor or with respect to
which Debtor is entitled to vote and act, subject to the understanding
that such proxy may not be exercised unless a Default exists. The proxy
herein granted is coupled with an interest, is irrevocable, and shall
continue until the Obligation has been paid and performed in full.

(e) CERTAIN PROCEEDS. Notwithstanding any contrary
provision herein, any and all stock dividends or distributions in
property made on or in respect of any Pledged Securities, and any
proceeds of any Pledged Securities, whether such dividends,
distributions, or proceeds result from a subdivision, combination, or
reclassification of the outstanding capital stock of any issuer thereof
or as a result of any merger, consolidation, acquisition, or other
exchange of assets to which any issuer may be a party, or otherwise,
shall be part of the Collateral hereunder, shall, if received by Debtor,
be held in trust for the benefit of Secured Party, and shall forthwith
be delivered to Secured Party (accompanied by proper instruments of
assignment and/or stock and/or bond powers executed by Debtor in
accordance with Secured Party's instructions) to be held subject to the
terms of this Security Agreement. Any cash proceeds of Collateral which
come into the possession of Secured Party (including, without
limitation, insurance proceeds) may, at Secured Party's option, be
applied in whole or in part to the Obligation (to the extent then due),
be released in whole or in part to or on the written instructions of
Debtor for any general or specific purpose, or be retained in whole or
in part by Secured Party as additional Collateral. Any cash Collateral
in the possession of Secured Party may be invested by Secured Party in
certificates of deposit issued by Secured Party (if Secured Party issues
such certificates) or by any state or national bank having combined
capital and surplus greater than $100,000,000 with a rating from ▇▇▇▇▇'▇
and S&P of P-1 and A-1+, respectively, or in securities issued or
guaranteed by the United States of America or any agency thereof.
Secured Party shall never be obligated to make any such investment and
shall never have any liability to Debtor for any loss which may result
therefrom. All interest and other amounts earned from any investment of
Collateral may be dealt with by Secured Party in the same manner as
other cash Collateral. The provisions of this subparagraph are
applicable whether or not a Default or Potential Default exists.

(f) USE AND OPERATION OF COLLATERAL. Should any Collateral
come into the possession of Secured Party, Secured Party may use or
operate such Collateral for the purpose of preserving it or its value
pursuant to the order of a court of appropriate jurisdiction or in
accordance with any other Rights held by Secured Party in respect of
such Collateral. Debtor covenants to promptly reimburse and pay to
Secured Party, at Secured Party's request, the amount of all reasonable
expenses (including, without limitation, the cost of any insurance and
payment of Taxes or other charges) incurred by Secured Party in
connection with its custody and preservation of Collateral, and all such
expenses, costs, Taxes, and other charges shall bear interest at the
Default Rate until repaid and, TOGETHER WITH such interest, shall be
payable by Debtor to Secured Party upon demand and shall become part of
the Obligation. However, the risk of accidental loss or damage to, or
diminution in

14 EXHIBIT D

value of, Collateral is on Debtor, and Secured Party shall have no
liability whatever for failure to obtain or maintain insurance, nor to
determine whether any insurance ever in force is adequate as to amount
or as to the risks insured. With respect to Collateral that is in the
possession of Secured Party, Secured Party shall have no duty to fix
or preserve Rights against prior parties to such Collateral and shall
never be liable for any failure to use diligence to collect any amount
payable in respect of such Collateral, but shall be liable only to
account to Debtor for what it may actually collect or receive thereon.
The provisions of this subparagraph are applicable whether or not a
Default exists.

(g) CASH COLLATERAL ACCOUNT. If a Default exists, Secured
Party shall have, and Debtor hereby grants to Secured Party, the Right
and authority to transfer all funds on deposit in the Deposit Accounts
to a CASH COLLATERAL ACCOUNT (herein so called) maintained with a
depository institution acceptable to Secured Party and subject to the
exclusive direction, domain, and control of Secured Party, and no
disbursements or withdrawals shall be permitted to be made by Debtor
from such Cash Collateral Account. Such Cash Collateral Account shall
be subject to the Security Interest and Liens in favor of Secured Party
herein created, and Debtor hereby grants a security interest to Secured
Party on behalf of Lenders in and to, such Cash Collateral Account and
all checks, drafts, and other items ever received by Debtor for deposit
therein. Furthermore, if a Default exists, Secured Party shall have the
Right, at any time in its discretion without notice to Debtor, (i) to
transfer to or to register in the name of Secured Party or any Lender or
nominee any certificates of deposit or deposit instruments constituting
Deposit Accounts and shall have the Right to exchange such certificates
or instruments representing Deposit Accounts for certificates or
instruments of smaller or larger denominations and (ii) to take and
apply against the Obligation any and all funds then or thereafter on
deposit in the Cash Collateral Account or otherwise constituting Deposit
Accounts.

(h) POWER OF ATTORNEY. Debtor hereby irrevocably constitutes
and appoints Secured Party as Debtor's attorney-in-fact, with full
irrevocable power and authority in the place and stead of Debtor and in
the name of Debtor, Secured Party, Lenders, or otherwise, from time to
time in Secured Party's discretion, for the sole purpose of carrying out
the terms of this Security Agreement and, to the extent permitted by
applicable Law, to take any action and to execute any document and
instrument which Secured Party may deem necessary or advisable to
accomplish the following when a Default exists:

(i) to transfer any and all funds on deposit in the
Deposit Accounts to the Cash Collateral Account as set forth in
herein;

(ii) to receive, endorse, and collect any drafts or
other instruments or documents in connection with CLAUSE (b)
above and this CLAUSE (g);

(iii) to use the Patents and Trademarks or to grant or
issue any exclusive or non-exclusive license under the Patents
and Trademarks to anyone else, and to perform any act necessary
for the Secured Party to assign, pledge, convey, or otherwise
transfer title in or dispose of the Patents and Trademarks to
any other Person; and

(iv) to execute on behalf of Debtor any continuation
statement with respect to the Security Interests created hereby,
and to do any and all acts and things to protect and preserve
the Collateral, including, without limitation, the protection
and prosecution of all Rights included in the Collateral.

(i) PURCHASE MONEY COLLATERAL. To the extent that Secured
Party or any Lender has advanced or will advance funds to or for the
account of Debtor to enable Debtor to purchase or

15 EXHIBIT D

otherwise acquire Rights in Collateral, Secured Party or such Lender,
at its option, may pay such funds (i) directly to the Person from whom
Debtor will make such purchase or acquire such Rights, or (ii) to
Debtor, in which case Debtor covenants to promptly pay the same to such
Person, and forthwith furnish to Secured Party evidence satisfactory to
Secured Party that such payment has been made from the funds so
provided.

(j) SUBROGATION. If any of the Obligation is given in
renewal or extension or applied toward the payment of indebtedness
secured by any Lien, Secured Party shall be, and is hereby, subrogated
to all of the Rights, titles, interests, and Liens securing the
indebtedness so renewed, extended, or paid.

(k) INDEMNIFICATION. Debtor hereby assumes all liability
for the Collateral, for the Security Interest, and for any use,
possession, maintenance, and management of, all or any of the
Collateral, including, without limitation, any Taxes arising as a result
of, or in connection with, the transactions contemplated herein, and
agrees to assume liability for, and to indemnify and hold Secured Party
and each Lender harmless from and against, any and all claims, causes of
action, or liability, for injuries to or deaths of Persons and damage to
property, howsoever arising from or incident to such use, possession,
maintenance, and management, whether such Persons be agents or employees
of Debtor or of third parties, or such damage be to property of Debtor
or of others. Debtor agrees to indemnify, save, and hold Secured Party
and each Lender harmless from and against, and covenants to defend
Secured Party and each Lender against, any and all losses, damages,
claims, costs, penalties, liabilities, and expenses (collectively,
"CLAIMS"), including, without limitation, court costs and attorneys'
fees, AND ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF SECURED
PARTY OR ANY LENDER, OR ANY OF THEIR RESPECTIVE OFFICERS, EMPLOYEES,
AGENTS, ADVISORS, EMPLOYEES, OR REPRESENTATIVES, howsoever arising or
incurred because of, incident to, or with respect to Collateral or any
use, possession, maintenance, or management thereof; PROVIDED, HOWEVER,
that the indemnity set forth in this PARAGRAPH 8(K) will not apply to
Claims caused by the gross negligence or willful misconduct of Secured
Party or any Lender.

22. ACKNOWLEDGMENT OF REGULATORY CONSIDERATIONS

(a) NO PROHIBITED TRANSFERS. It is hereby acknowledged that
assignment or transfer of control of the FCC Licenses without the prior
approval of the FCC may constitute a prohibited transfer in violation of
FCC rules and regulations. Secured Party agrees that exercise of its
Rights hereunder, including transfer of FCC Licenses upon the occurrence
of a Default or Potential Default, shall be effected only after the
obtaining of any necessary approvals for such exercise.

(b) ACTIONS BY DEBTOR. If counsel to Secured Party
reasonably determines that the consent of the FCC is required in
connection with any of the actions which may be taken by Secured Party
on behalf of Lenders in the exercise of their Rights hereunder or under
the Loan Papers, then Debtor, at its sole cost and expense, agrees to
use its best efforts to secure such consent and to cooperate with
Secured Party and Lenders in any action commenced by Secured Party to
secure such consent and in such case Debtor shall retain control of its
respective FCC Licenses until the FCC shall have granted its consent to
the transfer of the FCC Licenses and related permits. Upon the
occurrence and during the continuation of a Default or Potential
Default, Debtor shall promptly execute or cause the execution of all
applications, certificates, instruments, and other documents and papers
that the Secured Party may be required to file in order to obtain any
necessary governmental consent, approval, or authorization, and if
Debtor fails or refuses to execute such documents, then, on the order of
any court of competent jurisdiction, the Clerk of the Court with
jurisdiction may

16 EXHIBIT D

execute such documents on behalf of Debtor. In addition, Debtor shall
execute such applications and other documents and will take such other
action as may be required in order for Secured Party to obtain from the
FCC consent to operate the System, through a receiver or otherwise,
during the time the Secured Party seeks to obtain a purchaser for the
System and to submit any sale of the Systems to the FCC for approval.
Debtor recognizes that FCC Licenses, franchises, and other similar
agreements or authorizations are unique assets which (or the control of
which) may have to be transferred in order for Lenders adequately to
realize the value of their Security Interests. Debtor further
recognizes that a violation of this covenant would result in
irreparable harm to Lenders for which monetary damages are not readily
ascertainable and which might not fully compensate such Lenders.
Therefore, in addition to any other remedy which may be available to
Lenders, at Law or in equity, Secured Party on behalf of Lenders shall
have the remedy of specific performance of the provisions of this
subsection.

(c) FCC APPROVAL. Notwithstanding anything to the contrary
contained in this Security Agreement, Secured Party will not take any
action pursuant to this Security Agreement or any of the documents
executed pursuant hereto which would constitute an assignment of an FCC
License or any transfer of control of an FCC License if such assignment
of license or transfer of control would require under then-existing Law
(including the written rules and regulations promulgated by the FCC or
such other regulatory authority with jurisdiction) the prior approval of
the FCC or such other regulatory authority with jurisdiction, without
first obtaining such approval. Debtor agrees to take, or cause to be
taken, any action which Secured Party may reasonably request in order to
obtain and enjoy the full Rights and benefits granted to Secured Party
by this Security Agreement and any other instruments or agreements
executed pursuant hereto, including, without limitation, at Debtor's
cost and expense, the exercise of its best efforts to cooperate in
obtaining FCC approval of any action or transaction contemplated by this
Security Agreement or any other instrument or agreement executed
pursuant hereto which is then required by Law.

(d) SUBSEQUENT ACTIONS BY DEBTOR. Debtor agrees that if,
for any reason, the FCC or any such other regulatory authority with
jurisdiction does not approve within a reasonable period of time the
initial application for approval of the transfer of the FCC Licenses,
then PARAGRAPHS 9(b) and (c) above hereof shall be applicable to any
subsequent application for transfer of the FCC Licenses pursuant to
action taken by Secured Party in the exercise of its Rights hereunder or
under the Loan Papers. With respect to each subsequent proposed
purchaser(s), Debtor agrees to execute all such applications and other
documents and take all such other action as may be reasonably requested
by Secured Party at any time and from time to time in order to obtain
the approval by the FCC or any other regulatory authorities. Exercise
by Secured Party of the Right to such cooperation shall not be exhausted
by the initial or any subsequent exercise thereof.

23. MISCELLANEOUS.

(a) CONTINUING SECURITY INTEREST. This Security Agreement
creates a continuing security interest in the Collateral and shall (i)
remain in full force and effect until the termination of the obligations
of Lenders to advance Borrowings under the Credit Agreement, the payment
in full of the Obligation, and the expiration of all Financial ▇▇▇▇▇▇;
(ii) be binding upon Debtor, its successors, and assigns; and (iii)
inure to the benefit of and be enforceable by the Secured Party,
Lenders, and their respective successors, transferees, and assigns.
Without limiting the generality of the foregoing CLAUSE (iii), the
Secured Party and Lenders may assign or otherwise transfer any of their
respective Rights under this agreement to any other Person in accordance
with the terms and provisions of SECTION 13.13 of the Credit Agreement,
and to the extent of such assignment or transfer such Person shall
thereupon become vested with all the Rights and benefits in respect
thereof granted herein or

17 EXHIBIT D

otherwise to the Secured Party or Lenders, as the case may be. Upon
payment in full of the Obligation, the termination of the commitment
of Lenders to extend credit, and the expiration of all Financial
▇▇▇▇▇▇, Debtor shall be entitled to the return, upon its request and
at its expense, of such of the Collateral as shall not have been sold
or otherwise applied pursuant to the terms hereof.

(b) REFERENCE TO MISCELLANEOUS PROVISIONS. This Security
Agreement is one of the "LOAN PAPERS" referred to in the Credit
Agreement, and all provisions relating to Loan Papers set forth in
SECTIONS 13 of the Credit Agreement, other than the provisions set forth
in SECTIONS 13.7, are incorporated herein by reference, the same as if
set forth herein verbatim.

(c) TERM. Upon full and final payment and performance of
the Obligation, this agreement shall thereafter terminate upon receipt
by Secured Party of Debtor's written notice of such termination;
PROVIDED THAT no Obligor, if any, on any of the Collateral shall ever be
obligated to make inquiry as to the termination of this agreement, but
shall be fully protected in making payment directly to Secured Party
until actual notice of such total payment of the Obligation is received
by such Obligor.

(d) ACTIONS NOT RELEASES. The Security Interest and
Debtor's obligations and Secured Party's Rights hereunder shall not be
released, diminished, impaired, or adversely affected by the occurrence
of any one or more of the following events: (i) the taking or accepting
of any other security or assurance for any or all of the Obligation;
(ii) any release, surrender, exchange, subordination, or loss of any
security or assurance at any time existing in connection with any or all
of the Obligation; (iii) the modification of, amendment to, or waiver of
compliance with any terms of any of the other Loan Papers without the
notification or consent of Debtor, EXCEPT as required therein (the Right
to such notification or consent being herein specifically waived by
Debtor); (iv) the insolvency, bankruptcy, or lack of corporate or trust
power of any party at any time liable for the payment of any or all of
the Obligation, whether now existing or hereafter occurring; (v) any
renewal, extension, or rearrangement of the payment of any or all of the
Obligation, either with or without notice to or consent of Debtor, or
any adjustment, indulgence, forbearance, or compromise that may be
granted or given by Secured Party or any Lender to Debtor; (vi) any
neglect, delay, omission, failure, or refusal of Secured Party or any
Lender to take or prosecute any action in connection with any other
agreement, document, guaranty, or instrument evidencing, securing, or
assuring the payment of all or any of the Obligation; (vii) any failure
of Secured Party or any Lender to notify Debtor of any renewal,
extension, or assignment of the Obligation or any part thereof, or the
release of any security, or of any other action taken or refrained from
being taken by Secured Party or any Lender against Debtor or any new
agreement between or among Secured Party or one or more Lenders and
Debtor, IT BEING UNDERSTOOD THAT neither Secured Party nor any Lender
shall be required to give Debtor any notice of any kind under any
circumstances whatsoever with respect to or in connection with the
Obligation, including, without limitation, notice of acceptance of this
Security Agreement or any Collateral ever delivered to or for the
account of Secured Party hereunder; (viii) the illegality, invalidity,
or unenforceability of all or any part of the Obligation against any
party obligated with respect thereto by reason of the fact that the
Obligation, or the interest paid or payable with respect thereto,
exceeds the amount permitted by Law, the act of creating the Obligation,
or any part thereof, is ULTRA ▇▇▇▇▇, or the officers, partners, or
trustees creating same acted in excess of their authority, or for any
other reason; or (ix) if any payment by any party obligated with respect
thereto is held to constitute a preference under applicable Laws or for
any other reason Secured Party or any Lender is required to refund such
payment or pay the amount thereof to someone else.

18 EXHIBIT D

(e) WAIVERS. EXCEPT to the extent expressly otherwise
provided herein or in other Loan Papers and to the fullest extent
permitted by applicable Law, Debtor waives (i) any Right to require
Secured Party or any Lender to proceed against any other Person, to
exhaust its Rights in Collateral, or to pursue any other Right which
Secured Party or any Lender may have; (ii) with respect to the
Obligation, presentment and demand for payment, protest, notice of
protest and nonpayment, and notice of the intention to accelerate; and
(iii) all Rights of marshaling in respect of any and all of the
Collateral.

(f) FINANCING STATEMENT. Secured Party shall be entitled at
any time to file this agreement or a carbon, photographic, or other
reproduction of this agreement, as a financing statement, but the
failure of Secured Party to do so shall not impair the validity or
enforceability of this agreement.

(g) AMENDMENTS. This instrument may be amended only by an
instrument in writing executed jointly by Debtor and Secured Party, and
supplemented only by documents delivered or to be delivered in
accordance with the express terms hereof.

(h) MULTIPLE COUNTERPARTS. This Security Agreement has been
executed in a number of identical counterparts, each of which shall be
deemed an original for all purposes and all of which constitute,
collectively, one agreement; but, in making proof of this Security
Agreement, it shall not be necessary to produce or account for more than
one such counterpart.

(i) PARTIES BOUND; ASSIGNMENT. This Security Agreement
shall be binding on Debtor and Debtor's heirs, legal representatives,
successors, and assigns and shall inure to the benefit of Secured Party
and Secured Party's successors and assigns.

(i) Secured Party is the agent for each Lender under
the Credit Agreement, the Security Interest and all Rights
granted to Secured Party hereunder or in connection herewith are
for the ratable benefit of each Lender, and Secured Party may,
without the joinder of any Lender, exercise any and all Rights
in favor of Secured Party or Lenders hereunder, including,
without limitation, conducting any foreclosure sales hereunder,
and executing full or partial releases hereof, amendments or
modifications hereto, or consents or waivers hereunder. The
Rights of each Lender VIS-A-VIS Secured Party and each other
Lender may be subject to one or more separate agreements between
or among such parties, but Debtor need not inquire about any
such agreement or be subject to any terms thereof unless Debtor
specifically joins therein; and consequently, neither Debtor nor
Debtor's heirs, personal representatives, successors, and
assigns shall be entitled to any benefits or provisions of any
such separate agreements or be entitled to rely upon or raise as
a defense, in any manner whatsoever, the failure or refusal of
any party thereto to comply with the provisions thereof.

(ii) Debtor may not, without the prior written
consent of Secured Party, assign any Rights, duties, or
obligations hereunder.

(j) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED AS TO
ITS VALIDITY, INTERPRETATION, AND EFFECT IN ACCORDANCE WITH THE LAWS OF
THE STATE OF TEXAS, EXCEPT AS REQUIRED BY MANDATORY PROVISIONS OF LAW
AND EXCEPT IF THE VALIDITY OR PERFECTION OF THE SECURITY INTERESTS
HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR
COLLATERAL, ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE

▇▇ ▇▇▇▇▇▇▇ ▇

▇▇▇▇▇ ▇▇ ▇▇▇▇▇. UNLESS THE CONTEXT OTHERWISE REQUIRES, ALL TERMS USED
HEREIN WHICH ARE DEFINED IN THE UNIFORM COMMERCIAL CODE AS ENACTED IN
THE STATE OF TEXAS SHALL HAVE THE MEANINGS THEREIN STATED.

First Union National Bank, as Co-Documentation Agent
Each Lender named in SCHEDULE 2.1 to the Credit Agreement referred to below

RE: CREDIT AGREEMENT FOR ▇▇▇▇▇▇/SYGNET OPERATING COMPANY

Ladies and Gentlemen:

We have acted as counsel to ▇▇▇▇▇▇/Sygnet Operating Company (together with
its successor by merger Sygnet Wireless, Inc., "BORROWER"), and its Subsidiaries
(collectively with Borrower, the "COMPANIES") in connection with the Credit
Agreement, dated as of December 23, 1998 (as amended, modified, supplemented, or
restated from time to time, the "CREDIT AGREEMENT"), among Borrower,
NationsBank, N.A., as Administrative Agent, ▇▇▇▇▇▇ Commercial Paper Inc. and PNC
Bank, National Association, as Co-Syndication Agents, Toronto Dominion (Texas),
Inc. and First Union National Bank, as Co-Documentation Agents, and Lenders
named on SCHEDULE 2.1 to the Credit Agreement ("LENDERS"). In addition, we have
also acted as counsel to ▇▇▇▇▇▇ Operating Company ("DOC") and ▇▇▇▇▇▇/Sygnet
Communications Company ("D/S COMPANY") in connection with D/S Company's
acquisition of Borrower's stock from DOC (the "▇▇▇▇▇▇ ACQUISITION").

This opinion is delivered pursuant to SECTION 7.1 of the Credit Agreement
and PARAGRAPH 11 of SCHEDULE 7.1 to the Credit Agreement. Except as otherwise
defined herein, each capitalized term used herein has the meaning given to such
term in the Credit Agreement.

In arriving at the opinions expressed below, we have examined such
corporate documents and records of the Companies and such certificates of public
officials and of officers of the Companies, other documents, and matters of law
as we deemed necessary or appropriate, including, without limitation, originals
or copies of (a) the Credit Agreement, (b) the Notes, (c) the Guaranty executed
by Sygnet Communications, Inc., (d) the Pledge, Assignment, and Security
Agreement executed by Borrower in favor of Lender, (e) the Pledge, Assignment,
and Security Agreement executed by Sygnet Communications, Inc. in favor of
Lender (collectively with (d) above, the "SECURITY AGREEMENTS"), (f) Financing
Statements showing Borrower, as Debtor, and Administrative Agent, as Secured
Party, to be filed in appropriate jurisdictions; (g) Financing Statements
(collectively with (e) above, the "FINANCING STATEMENTS") showing Sygnet
Communications, Inc., as Debtor, and Administrative Agent, as Secured Party, to
be filed in appropriate jurisdictions; and (h) other Collateral Documents (all
of the foregoing are collectively, the "TRANSACTION DOCUMENTS"); additionally,
we have examined [describe documents evidencing the ▇▇▇▇▇▇ Acquisition] (the
"▇▇▇▇▇▇ ACQUISITION DOCUMENTS") .

EXHIBIT G-1

Based upon the foregoing, we are of the opinion that:

1. Each Company, DOC, and D/S Company (a) is a corporation validly
existing and in good standing under the Laws of its state of incorporation, (b)
is duly qualified to transact business as a foreign corporation in each
jurisdiction where the nature and extent of its business and properties require
the same, and (c) possesses all requisite corporate authority and power to
conduct its business and execute, deliver, and comply with the terms of each of
the Transaction Documents, the ▇▇▇▇▇▇ Acquisition Documents, and the Sygnet
Merger Documents to which such Company is a party, which have been duly
authorized and approved by all necessary corporate action and for which no
approval or consent of any Person or Governmental Authority is required which
has not been obtained.

2. Each Company has duly executed and delivered each Transaction Document
and each Sygnet Merger Document, to which such Company is a party.

3. Each Transaction Document and Sygnet Merger Document to which any
Company is party evidence the valid and legally binding obligations of such
Company, enforceable against such Company in accordance with their terms, EXCEPT
as the enforcement may be limited by Debtor Relief Laws and EXCEPT that the
remedies available with respect thereto may be subject to general principles of
equity (regardless of whether such remedies are sought in a proceeding in equity
or at law).

4. The execution, delivery, and performance of and compliance with the
terms of the Transaction Documents and the Sygnet Merger Documents will not
cause any Company to be in violation of its respective Articles or Certificates
of Incorporation or Bylaws.

5. The execution, delivery, and performance of and compliance with the
terms of the Transaction Documents and the Sygnet Merger Documents will not
cause any Company to be in violation of any Laws other than such violations
which will not, individually or collectively, be a Material Adverse Event.

6. The execution, delivery, and performance of and compliance with the
terms of the Transaction Documents and the Sygnet Merger Documents will not
cause any Company to be in default under any material, written, or oral
agreements, contracts, commitments, or understandings to which any Company is a
party.

7. Each Company is in compliance in all material respects with all
applicable Laws, federal, state, and local (including without limitation,

required by reason of or in connection with the execution and performance of the
Transaction Documents and the Sygnet Merger Documents.

8. No Company is involved in, nor are we aware of the threat of, any
Litigation which is reasonably likely to be determined adversely to any Company.
There are no outstanding orders or judgments for the payment of money in excess

investigation, EXCEPT as set forth on such schedule, no Company (a) has any
other Subsidiaries or (b) has transacted business under any other corporate or
trade name in the five-year period preceding the date hereof.

10. No Company, and no Affiliate of any Company, is (a) subject to
regulation under the Public Utility Holding Company Act of 1935, the Federal

13. The interest payable by Borrower pursuant to the Notes and Credit
Agreement is not in violation of the usury Laws of the State of Texas or the

the benefit of Lenders in the Collateral, to the extent that the filing of
financing statements is effective to perfect security interests in the
Collateral, subject to the qualifications set forth in the Security Agreements
with respect to licenses issued by the FCC. No further action, including any
filing or recording of any document, is necessary in order to establish,
perfect, and maintain Lenders' security interests in the assets and the stock
created by the Security Agreements, EXCEPT for the periodic filing of
continuation statements with respect to financing statements filed under the
Uniform Commercial Code of the applicable jurisdiction.

3 EXHIBIT G-1

FORM OF OPINION OF SPECIAL REGULATORY COUNSEL
(▇▇▇▇▇▇/SYGNET)

[Firm Letterhead]

December ___, 1998

RE: CREDIT AGREEMENT FOR ▇▇▇▇▇▇/SYGNET OPERATING COMPANY

Ladies and Gentlemen:

We have acted as special communications regulatory counsel to
▇▇▇▇▇▇/Sygnet Operating Company (together with is its successor by merger,
Sygnet Wireless, Inc., "BORROWER"), and its Subsidiaries (collectively with
Borrower, the "COMPANIES") in connection with the Credit Agreement, dated as
of December 23, 1998 (as amended, modified, supplemented, or restated from
time to time, the "CREDIT AGREEMENT"), among Borrower, NationsBank, N.A., as
Administrative Agent, ▇▇▇▇▇▇ Commercial Paper Inc. and PNC Bank, National
Association, as Co-Syndication Agents, Toronto Dominion (Texas), Inc. and
First Union National Bank, as Co-Documentation Agents, and Lenders named on
SCHEDULE 2.1 to the Credit Agreement ("LENDERS").

This opinion is delivered pursuant to SECTION 7.1 of the Credit
Agreement and PARAGRAPH 12 of SCHEDULE 7.1 to the Credit Agreement. Except
as otherwise defined herein, each capitalized term used herein has the
meaning given to such term in the Credit Agreement.

We have examined the articles of incorporation, bylaws, and partnership
agreements, as applicable, of the Companies, the Loan Papers, the
certificates of public convenience and necessity and similar authorizations
issued to the Companies by the Federal Communications Commission ("FCC") and
each state public utility commission ("PUC") that, on the date of this
opinion, exercises jurisdiction over the Companies (each such PUC, an
"APPLICABLE PUC"). See SCHEDULE I for the list of Applicable PUCs as of the
date of this opinion. Our opinion is limited to the provisions of the
Communications Act of 1934, as amended, 47 U.S.C. Section 151 ET SEQ. (the
"COMMUNICATIONS ACT"), and all laws administered by, and all rules,
regulations, and published policies of, the FCC and Applicable PUCs, and we
express no opinion and assume no responsibility as to the applicability of
any other laws.

Based upon the foregoing, we are of the opinion that:

1. The consummation of the Sygnet Merger and the execution and
delivery of the Credit Agreement and the Loan Papers by Borrower and the
performance by the Companies of the Obligation will not violate any law,
rule, regulation, or policy of the FCC or any Applicable PUC.

EXHIBIT G-2

2. The execution and delivery of a Guaranty by the Subsidiaries party
thereto and the performance by such Subsidiaries of their respective
obligations thereunder will not violate any law, rule, regulation, or policy
of the FCC or any Applicable PUC.

3. Each Company holds all licenses required by the FCC and all other
certificates or licenses required by any Applicable PUC for the construction
and operation, in accordance with the Communications Act and the PUC Laws, of
each of the cellular systems owned or leased by the Companies (collectively,
the "CELLULAR SYSTEMS"). All of the certificates and licenses are duly and
validly held by the applicable Company, and all such certificates and
licenses are in full force and effect without conditions, other than such
conditions that are generally applicable to such licenses and other
certificates.

4. The Companies' execution and delivery, and performance and
compliance with the terms and provisions of the Credit Agreement and the
other Loan Papers and the Sygnet Merger Documents: (a) will not result in a
violation of the Communications Act or any PUC Laws: (b) will not cause any
cancellation, termination, revocation, forfeiture, or material impairment of
any FCC or PUC authorization, certificate, or license; and (c) will not
require further notice to or the approval of the FCC or any Applicable PUC
[, EXCEPT in the states where applications for authority are currently pending]
.

5. The ownership and operation by the Companies of their Systems and
other business operations are in compliance in all material respects with the
Communications Act (including, without limitation, all FCC filing, reporting,
prior approval, and similar requirements).

6. No approval, authorization, consent, adjudication, or order of the
FCC or any Applicable PUC which has not been obtained by the Companies as of
this date is required to be obtained by the Companies in connection with the
consummation of the Sygnet Merger, the execution and delivery of the Loan
Papers, the borrowing under the Credit Agreement, the payment or performance
of the Obligations by the Companies or the creations of the Liens in favor of
Lenders under the Loan Papers.

7. To the best of our knowledge: (a) there is no outstanding decree or
order that has been issued by the FCC or any Applicable PUC against any
Company and no pending or threatened litigation, proceedings, notice of
violation, order to show cause, complaint, inquiry, or investigation before
the FCC or any Applicable PUC (i) relating to any Company or relating to its
Cellular Systems or business operations that might result in the
cancellation, termination, revocation, forfeiture, or material impairment of
any FCC or PUC authorizations, certificates, or licenses, or have any
material adverse effect upon, or cause material disruption to, any Company or
the ownership or operation of such Cellular Systems or business operations or
(ii) seeking to prohibit, restrict, or delay consummation of the transactions
contemplated by the Loan Papers, the Sygnet Merger Documents, or fulfillments
of any conditions under the Loan Papers of the Sygnet Merger Documents; and
(b) no action has been taken by the FCC or any Applicable PUC which might
now, or after notice or lapse of time, or both, result in the cancellation,
termination, revocation, forfeiture, or material impairment of any FCC or PUC
authorizations, certificates, or licenses, or have any material adverse
effect upon, or material disruption to, any Company or the ownership or
operation of their Cellular Systems or business operations.

This opinion letter is provided to Administrative Agent, Syndication
Agent, Documentation Agent, each Lender, and ▇▇▇▇▇▇ and ▇▇▇▇▇, LLP, and their
respective participants, assignees, or other transferees, by us in our
capacity as special communications regulatory counsel to the Companies.

FORM OF OPINION OF OHIO COUNSEL
(▇▇▇▇▇▇/SYGNET)

[Firm Letterhead]

December ___, 1998

RE: CREDIT AGREEMENT FOR ▇▇▇▇▇▇/SYGNET OPERATING COMPANY

Ladies and Gentlemen:

We have acted as special [ ] counsel to
▇▇▇▇▇▇/Sygnet Operating Company (together with its successor by merger,
Sygnet Wireless, Inc., "BORROWER"), and its Subsidiaries (collectively with
Borrower, the "COMPANIES") in connection with the Credit Agreement, dated as
of December 23, 1998 (as amended, modified, supplemented, or restated from
time to time, the "CREDIT AGREEMENT"), between Borrower, NationsBank, N.A.,
as Administrative Agent, ▇▇▇▇▇▇ Commercial Paper Inc. and PNC Bank, National
Association, as Co-Syndication Agents, Toronto Dominion (Texas), Inc. and
First Union National Bank, as Co-Documentation Agents, and Lenders named on
SCHEDULE 2.1 to the Credit Agreement ("LENDERS").

This opinion is delivered pursuant to SECTION 7.1 of the Credit
Agreement and PARAGRAPH 13 of SCHEDULE 7.1 to the Credit Agreement. Except
as otherwise defined herein, each capitalized term used herein has the
meaning given to such term in the Credit Agreement.

As to matters of law in the State of Ohio (the "SUBJECT JURISDICTION"),
we have acted as your special counsel in connection with the preparation of
the Credit Agreement and related Loan Papers. In that connection, we have
examined such certificates of public officials and of officers of Borrower,
other documents, and matters of law as we deemed necessary or appropriate,
including, without limitation, originals or copies of the Loan Papers and the
opinions hereinafter stated, and counterparts of the following documents
(collectively, the "TRANSACTION DOCUMENTS"):

(a) Credit Agreement;

(b) Guaranty executed by Sygnet Communications, Inc.;

EXHIBIT G-3

(d) Pledge, Assignment, and Security Agreement (collectively with
(c) above, the "SECURITY AGREEMENTS") naming Sygnet Communications, Inc.,
as Debtor, and Administrative Agent, as Secured Party;

(e) Financing Statements showing Borrower, as Debtor, and
Administrative Agent, as Secured Party, to be filed in appropriate
jurisdictions in the State of Ohio;

(f) Financing Statements (collectively with (e) above, the
"FINANCING STATEMENTS") showing Sygnet Communications, Inc., as Debtor, and
Administrative Agent, as Secured Party, to be filed in appropriate
jurisdictions in the State of Ohio;

(g) The Sygnet Merger Documents.

Based on the foregoing, subject to the comments and exceptions
hereinafter stated, and limited in all respects to the laws of the Subject
Jurisdiction and the United States of America, it is our opinion that:

1. Each Company (a) is a corporation validly existing and in good
standing under the Laws of its state of incorporation, (b) is duly qualified
to transact business as a foreign corporation in each jurisdiction where the
nature and extent of its business and properties require the same, and (c)
possesses all requisite corporate authority and power to conduct its business
and execute, deliver, and comply with the terms of the Transaction Documents
and the Sygnet Merger Documents to which such Company is a party, which have
been duly authorized and approved by all necessary corporate action and for
which no approval or consent of any Person or Governmental Authority is
required which has not been obtained.

2. The Loan Papers and the Sygnet Merger Documents to which any
Company is a party evidence the valid and legally binding obligations of such
Company, enforceable in accordance with their respective terms, EXCEPT as the
enforcement may be limited by Debtor Relief Laws and EXCEPT that the remedies
available with respect thereto may be subject to general principles of equity
(regardless of whether such remedies are sought in a proceeding in equity or
at law).

3. Each Company has duly executed and delivered each Loan Paper and each
Sygnet Merger Document, to which such Company is a party.

4. The execution, delivery, and performance of and compliance with the
terms of the Loan Papers and the Sygnet Merger Documents will not cause any
Company to be in violation of its respective Articles or Certificates of
Incorporation or Bylaws.

5. To the best of our knowledge, after reasonable investigation, no
Company is, nor will the execution, delivery, the performance of, and
compliance with the terms of the Loan Papers and the Sygnet Merger Documents
(and the Sygnet merger contemplated thereby) cause any Company to be, in
violation of any Laws other than such violations which will not, individually
or collectively, be a Material Adverse Event.

6. The Security Agreements and Financing Statements are in proper
recordable form, and constitute valid and binding obligations of the Companies
executing the same enforceable in accordance with their terms, EXCEPT as the
enforcement thereof may be limited by applicable bankruptcy, rearrangement,
receivership, reorganization, or similar Debtor Relief Laws from time to time in
effect and affecting the rights of creditors generally, and EXCEPT that the
remedies available with respect thereto may be subject to general principles of
equity (regardless of whether such remedies are sought in a proceeding in equity
or at law). The Financing Statements are legally sufficient under the laws of
the Subject Jurisdiction to perfect any security

2 EXHIBIT G-3

interests in favor of Administrative Agent, for the benefit of Lenders,
which may have attached to the Collateral therein described.

7. Under the laws of the Subject Jurisdiction, no mortgage,
documentary, stamp, or similar taxes, other than nominal recording fees, will
be payable in connection with the execution, delivery, or recording of the
Transaction Documents or any of the transactions contemplated thereby.

8. The Financing Statements should be filed with the Secretary of
State of and with at
the addresses set forth on SCHEDULE 1 hereto. When so filed and recorded,
the Transaction Documents shall create and perfect a valid and continuing
security interest in the Collateral described in the Transaction Documents,
to the extent that the filing of a financing statement in the Subject
Jurisdiction is effective to perfect the security interests granted in the
Collateral in favor of Administrative Agent, for the benefit of Lenders. No
further or subsequent filing, recording, or registration of the Transaction
Documents or any other instrument will be necessary in order to create,
perfect, or maintain the liens and security interests created an perfected by
the Transaction Documents, EXCEPT that within six months next prior to the
expiration of five years from the filing of the Financing Statements (and
each five years thereafter), Continuation Statements must be filed with the
Secretary of State of , all pursuant to the Uniform
Commercial Code as enacted in the Subject Jurisdiction.

9. You are not required, as a result of the transactions contemplated
in the Transaction Documents to qualify to do business in the Subject
Jurisdiction in order to receive the benefits of, or to exercise rights under
or in connection with, the Transaction Documents.

10. EXCEPT for the filing of the Financing Statements, no other
declarations or filings with, and no consents, waivers, approvals,
authorizations, or other actions by, any governmental or regulatory body of
the Subject Jurisdiction, including, without limitation, any environmental
protection agency or regulatory authority, are necessary in connection with
the execution and delivery by any Company of, and the performance of such
Company's obligations under or in connection with, the Transaction Documents,
or in connection with the granting of the security interests in the
Collateral and the exercise of Rights under the Transaction Documents.

11. The Sygnet Merger has been consummated in accordance with the
Sygnet Merger Documents and applicable Ohio Law. The Certificate of Merger
has been filed with the Secretary of State of Ohio and is in full force and
effect. The execution, delivery, and performance of the Sygnet Merger
Documents by the Companies party thereto were duly authorized and approved by
the respective shareholders of such Companies, and no other consents or
approvals of any Person or Governmental Authority and no other corporate
proceedings on the part of any such Company is necessary to authorize the
Sygnet Merger and the consummation of the transactions contemplated thereby,
other than such consent, approvals, or proceedings which have been previously
obtained or conducted, as the case may be. The Sygnet Merger Documents were
duly executed and delivered by the Companies party thereto and constitute the
legal, valid, and binding obligation of each such Company, enforceable in
accordance with its terms.

This opinion letter is provided to Lender, each assignee and participant
under the Credit Agreement, and ▇▇▇▇▇▇ and ▇▇▇▇▇, LLP.

Respectfully submitted,

any part of the Senior Debt or amend, modify, supplement, or restate, any of the

deal with all or any part of any property by whomsoever at any time pledged or

otherwise, including, without limitation, any prior perfection of a security
interest or Lien, any security interests and Liens now or hereafter held by
Subordinated Creditor in any Collateral for the Subordinated Debt shall be
junior and subordinate to any security interests and Liens now or hereafter held
by Administrative Agent, for the benefit of Lenders, in the same Collateral. So
long as the Senior Debt shall remain unpaid, Administrative Agent may at all
times in its sole discretion exercise any and all powers and Rights which it now
has or may hereafter acquire with respect to any of the Collateral securing the
Senior Debt, all without the necessity of obtaining any consent or approval of
Subordinated Creditor.

8. Each Subordinated Creditor represents and warrants that it is duly
organized, validly existing, and in good standing under the laws of its state of
organization and has the power and authority under the laws of such state and

its execution and performance of this Agreement have been taken and upon its
execution, this Agreement will constitute its valid and binding obligation
enforceable in accordance with its terms; and the making and performance of this

or other organizational documents, or result in any violation of or constitute a
default under any agreement by which it or any of its property is bound.

covenants and agrees that it will not modify or amend or permit modification or
amendment of the terms and conditions of the Subordinated Debt, without
obtaining the prior written consent of Administrative Agent.

effective unless in a writing signed by Administrative Agent, and each waiver
shall extend only to the specific instance involved and shall not impair or
affect Administrative Agent's Rights in any other respect at any other time.
Each Subordinated Creditor hereby waives all notices with respect

to the subject matter hereof, including, but not limited to, notice of
acceptance of this Agreement, of the making of loans or advances to the Borrower
or any extensions, renewals, or modifications thereof, releases of collateral
security or guarantors or other indulgences of any character, or of the
occurrence or declaration of any default or the taking of any collection or
enforcement action. THIS AGREEMENT SHALL BE CONSTRUED ACCORDING TO THE LAWS OF
THE STATE OF TEXAS.

12. This Agreement inures to the benefit of Administrative Agent, Lenders,
and their respective successors and assigns, and the Rights under this Agreement
may be assigned in whole or in part in connection with any partial or complete
assignment or transfer of the Senior Debt. Administrative Agent is
Administrative Agent for each Lender, and Administrative Agent may, without the
joinder of any Lender, exercise any and all Rights in favor of Lenders
hereunder. The Rights of each Lender VIS-A-VIS Administrative Agent and each
other Lender may be subject to one or more separate agreements between or among
such parties, but Subordinated Creditor need not inquire about any such
agreement or be subject to any terms thereof unless Subordinated Creditor
specifically joins therein; and, consequently, neither Subordinated Creditor nor
its heirs, personal representatives, successors, or assigns are entitled to any
benefits or provisions of any such separate agreements or are entitled to rely
upon or raise as a defense, in any manner whatsoever, the failure or refusal of
any party thereto to comply with the provisions thereof. This Agreement binds
Subordinated Creditor and its successors and assigns, and Subordinated Creditor
will advise each future holder of all or any part of the Subordinated Debt that
the Subordinated Debt is subordinated to the Senior Debt in the manner and to
the extent set forth in this Agreement.

13. This Agreement may be executed in a number of identical counterparts,
each of which is deemed an original for all purposes and all of which
constitute, collectively, one agreement; but, in making proof of this Agreement,
it is not necessary to produce or account for more than one counterpart.

14. Subject to the provisions of this Agreement and the Rights of
Administrative Agent hereunder, as between Borrower and Subordinated Creditor,
nothing herein contained shall impair the obligation of Borrower, which is
absolute and unconditional to pay the Subordinated Debt as and when the same
shall become due and payable in accordance with the terms thereof, or prevent
Subordinated Creditor upon default with respect to the Subordinated Debt, from
exercising all rights, powers, and remedies otherwise provided therein or by
applicable Law.
