ITEM 5.  OTHER EVENTS.

On April 5, 1999, Allegiance Telecom, Inc. issued a press release announcing
that it had closed a seven-year senior secured revolving credit facility with a
syndicate of lenders lead by Goldman Sachs Credit Partners L.P., TD Securities
(USA) Inc. and Morgan Stanley Senior Funding, Inc. A Current Report on Form 8-K
with respect to the press release and the credit and guaranty agreement was
filed by Allegiance Telecom on April 8, 1999, and included as Exhibit 10 a copy
of the credit and guaranty agreement.  Certain portions of the credit and
guaranty agreement were deleted, and such deleted portions were subject to a
request for confidential treatment from the Securities and Exchange Commission.
The purpose of this amendment is to re-file the credit and guaranty agreement
because Allegiance Telecom no longer seeks confidential treatment for certain
provisions previously redacted in the credit and guaranty agreement.

A copy of the redacted credit and guaranty agreement is attached as an exhibit
to this amended report and is incorporated herein by reference.

ITEM 7.  FINANCIAL STATEMENTS AND EXHIBITS.

(a) - (b)         None.

(c) The exhibits filed in response to Item 601 of Regulation S-K are listed in
the Exhibit Index starting on page E-1 of this report.

SECTION 2.  LOANS

         2.1.  LOANS

         (a)      Loans.

                  (i) During the Commitment Period, subject to the terms and
         conditions hereof, each Lender agrees to make Loans to Borrower in the
         aggregate amount up to but not exceeding such Lender's Commitment;
         provided, after giving effect to the making of any Loans in no event
         shall the Total Utilization of Commitments exceed the lesser of the (A)
         Commitments then in effect and (B) Loan Availability. Amounts borrowed
         pursuant to this Section 2.1(a) may be repaid and reborrowed during the
         Commitment Period. Each Lender's Commitment shall expire on the
         Commitment Termination Date and all Loans and all other amounts owed
         hereunder with respect to the Loans and the Commitments shall be paid
         in full no later than such date.

                  (ii) Loans shall be made in a minimum amount of $5,000,000 and
         integral multiples of $1,000,000 in excess thereof.

                  (iii) Whenever Borrower desires that Lenders make Loans,
         Borrower shall deliver to Administrative Agent a fully executed and
         delivered Funding Notice no later than 10:00 a.m. (New York City time)
         at least three Business Days in advance of the proposed Credit Date in
         the case of a Eurodollar Rate Loan, and at least one Business Day in
         advance of the proposed Credit Date in the case of a Loan that is a
         Base Rate Loan. Except as otherwise provided herein, a Funding Notice
         for a Loan that is a Eurodollar Rate Loan shall be irrevocable on and
         after the related Interest Rate Determination Date, and Borrower shall
         be bound to make a borrowing in accordance therewith.

                  (iv) Notice of receipt of each Funding Notice in respect of
         Loans, together with the amount of each Lender's Pro Rata Share
         thereof, if any, together with the applicable interest rate, shall be
         provided by Administrative Agent to each applicable Lender by
         telefacsimile with reasonable promptness, but not later than 2:00 p.m.
         (New York City time) on the same day as Administrative Agent's receipt
         of such Notice from Borrower.

                  (v) Each Lender shall make the amount of its Loan available to
         Administrative Agent not later than 12:00 Noon (New York City time) on
         the applicable Credit Date by wire transfer of same day funds in
         Dollars, at the Administrative Agent's Principal Office. Except as
         provided herein, upon satisfaction or waiver of the conditions
         precedent specified herein,


                                       31
<PAGE>   38

         Administrative Agent shall make the proceeds of such Loans available to
         Borrower on the applicable Credit Date by causing an amount of same day
         funds in Dollars equal to the proceeds of all such Loans received by
         Administrative Agent from Lenders to be credited to the account of
         Borrower at the Administrative Agent's Principal Office or such other
         account as may be designated in writing to Administrative Agent by
         Borrower.

         2.2. PRO RATA SHARES; AVAILABILITY OF FUNDS. (a) All Loans shall be
made by Lenders simultaneously and proportionately to their respective Pro Rata
Shares, it being understood that no Lender shall be responsible for any default
by any other Lender in such other Lender's obligation to make a Loan requested
hereunder nor shall the Commitment of any Lender be increased or decreased as a
result of a default by any other Lender in such other Lender's obligation to
make a Loan requested hereunder.

         (b) Unless Administrative Agent shall have been notified by any Lender
prior to the applicable Credit Date that such Lender does not intend to make
available to Administrative Agent the amount of such Lender's Loan requested on
such Credit Date, Administrative Agent may assume that such Lender has made such
amount available to Administrative Agent on such Credit Date and Administrative
Agent may, in its sole discretion, but shall not be obligated to, make available
to Borrower corresponding amount on such Credit Date. If such corresponding
amount is not in fact made available to Administrative Agent by such Lender,
Administrative Agent shall be entitled to recover such corresponding amount on
demand from such Lender together with interest thereon, for each day from such
Credit Date until the date such amount is paid to Administrative Agent, at the
customary rate set by Administrative Agent for the correction of errors among
banks for three Business Days and thereafter at the Base Rate. If such Lender
does not pay such corresponding amount forthwith upon Administrative Agent's
demand therefor, Administrative Agent shall promptly notify Borrower and
Borrower shall immediately pay such corresponding amount to Administrative Agent
together with interest thereon, for each day from such Credit Date until the
date such amount is paid to Administrative Agent, at the rate payable hereunder
for Base Rate Loans for such Type of Loans. Nothing in this Section 2.2(b) shall
be deemed to relieve any Lender from its obligation to fulfill its Commitments
hereunder or to prejudice any rights that Borrower may have against any Lender
as a result of any default by such Lender hereunder.

         2.3. USE OF PROCEEDS. The proceeds of the Loans shall be used by
Borrower and its Subsidiaries to provide purchase money financing for the cost
of design, development, acquisition, construction, installation, improvement,
transportation or integration of equipment, inventory, and network assets. No
portion of the proceeds of any Loan shall be used by Company or any of its
Subsidiaries in any manner that might cause such Loan or the application of such
proceeds to violate Regulation T, Regulation U or Regulation X of the Board of
Governors of the Federal Reserve System or any other regulation thereof or to
violate the Exchange Act, in each case as in effect on the date or dates of such
Loan and such use of proceeds.

         2.4. EVIDENCE OF DEBT; REGISTER; LENDERS' BOOKS AND RECORDS; NOTES. (a)
Each Lender shall maintain on its internal records an account or accounts the
Loans to Borrower by such Lender,


                                       32
<PAGE>   39

including the amounts of the Loans made by it and each repayment and prepayment
in respect thereof. Any such recordation shall be conclusive and binding on
Borrower, absent manifest error; provided, failure to make any such recordation,
or any error in such recordation, shall not affect any Lender's Commitments or
Borrower's Obligations in respect of any applicable Loans; and provided further,
in the event of any inconsistency between the Register and any Lender's records,
the recordations in the Register shall govern.

         (b) Administrative Agent shall maintain at its Principal Office a
register for the recordation of the names and addresses of Lenders and the
Commitments and Loans of each Lender from time to time (the "REGISTER"). 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.
Administrative Agent shall record in the Register the Commitments and the Loans,
and each repayment or prepayment in respect of the principal amount of the
Loans, and any such recordation shall be conclusive and binding on Borrower and
each Lender, absent manifest error; provided, failure to make any such
recordation, or any error in such recordation, shall not affect any Lender's
Commitments or Borrower's Obligations in respect of any Loan. Borrower hereby
designates TD to serve as Borrower's agent solely for purposes of maintaining
the Register as provided in this Section 2.4, and Borrower's hereby agrees that,
to the extent TD serves in such capacity, TD and its officers, directors,
employees, agents and affiliates shall constitute "Indemnitees".

         (c) If so requested by any Lender by written notice to Borrower (with a
copy to Administrative Agent) at least two Business Days prior to the Closing
Date, or at any time thereafter, Borrower shall execute and deliver to such
Lender (and/or, if applicable and if so specified in such notice, to any Person
who is an assignee of such Lender pursuant to Section 10.6) on the Closing Date
(or, if such notice is delivered after the Closing Date, promptly after
Borrower's receipt of such notice) a Note or Notes to evidence such Lender's
Loans.

         2.5. INTEREST PAYMENTS. (a) Except as otherwise set forth herein, each
Loan shall bear interest on the unpaid principal amount thereof from the date
made through maturity (whether by acceleration or otherwise) as follows:

                           (i)      if a Base Rate Loan, at the Base Rate plus
                  the Applicable Margin; or

                           (ii)     if a Eurodollar Rate Loan, at the Adjusted
                  Eurodollar Rate plus the Applicable Margin.

         (b) The basis for determining the rate of interest with respect to any
Loan and the Interest Period with respect to any Eurodollar Rate Loan, shall be
selected by Borrower and notified to Administrative Agent and Lenders pursuant
to the applicable Funding Notice or Conversion/Continuation Notice, as the case
may be; provided, no Eurodollar Rate Loan with an Interest Period in excess of
one month shall be available until the date that Syndication Agent notifies
Borrower that the primary syndication of the Loans and Commitments has been
completed, as determined by Syndication Agent, which date shall not in any event
be more than 90 days after the


                                       33
<PAGE>   40

Closing Date. If on any day a Loan is outstanding with respect to which a
Funding Notice or Conversion/Continuation Notice has not been delivered to
Administrative Agent in accordance with the terms hereof specifying the
applicable basis for determining the rate of interest, then for that day such
Loan shall be a Base Rate Loan.

         (c) In connection with Eurodollar Rate Loans there shall be no more
than eight (8) Interest Periods outstanding at any time. In the event Borrower
fails to specify an Interest Period for
any Eurodollar Rate Loan in the applicable Funding Notice or
Conversion/Continuation Notice, Borrower shall be deemed to have selected an
Interest Period of one month. A soon as practicable after 10:00 A.M. (New York
City time) on each Interest Rate Determination Date, Administrative Agent shall
determine (which determination shall, absent manifest error, be final,
conclusive and binding upon all parties) the interest rate that shall apply to
the Eurodollar Rate Loans for which an interest rate is then being determined
for the applicable Interest Period and shall promptly give notice thereof (in
writing or by telephone confirmed in writing) to Borrower and each Lender.

         (d) Interest payable pursuant to Section 2.5(a) shall be computed (i)
in the case of Base Rate Loans on the basis of a 365-day or 366-day year, as the
case may be, and (ii) in the case of Eurodollar Rate Loans, on the basis of a
360-day year, in each case for the actual number of days elapsed in the period
during which it accrues. In computing interest on any Loan, the date of the
making of such Loan or the first day of an Interest Period applicable to such
Loan or, with respect to a Base Rate Loan being converted from a Eurodollar Rate
Loan, the date of conversion of such Eurodollar Rate Loan to such Base Rate
Loan, as the case may be, shall be included, and the date of payment of such
Loan or the expiration date of an Interest Period applicable to such Loan or,
with respect to a Base Rate Loan being converted to a Eurodollar Rate Loan, the
date of conversion of such Base Rate Loan to such Eurodollar Rate Loan, as the
case may be, shall be excluded; provided, if a Loan is repaid on the same day on
which it is made, one day's interest shall be paid on that Loan.

         (e) Except as otherwise set forth herein, interest on each Loan shall
be payable in arrears on and to (i) each Interest Payment Date applicable to
that Loan; (ii) any prepayment of that Loan, whether voluntary or mandatory, to
the extent accrued on the amount being prepaid; and (iii) at maturity, including
final maturity.

         2.6. CONVERSION/CONTINUATION. (a) So long as no Default or Event of
Default shall have occurred and then be continuing, Borrower shall have the
option:

                  (i) to convert at any time all or any part of any Loan equal
         to $5,000,000 and integral multiples of $1,000,000 in excess of that
         amount from one Type of Loan to another Type of Loan; provided, a
         Eurodollar Rate Loan may only be converted into a Base Rate Loan on the
         expiration of the Interest Period applicable to such Eurodollar Rate
         Loan if Borrower shall pay all amounts due under Section 2.16 in
         connection with any such conversion; or


                                       34
<PAGE>   41

                  (ii) upon the expiration of any Interest Period applicable to
         any Eurodollar Rate Loan, to continue all or any portion of such Loan
         equal to $5,000,000 and integral multiples of $1,000,000 in excess of
         that amount as a Eurodollar Rate Loan.

         (b) The Borrower shall deliver a Conversion/Continuation Notice to
Administrative Agent no later than 10:00 A.M. (New York City time) at least one
Business Day in advance of the proposed conversion date (in the case of a
conversion to a Base Rate Loan) and at least three Business Days in advance of
the proposed conversion/continuation date (in the case of a conversion to, or a
continuation of, a Eurodollar Rate Loan). Except as otherwise provided herein, a
Conversion/Continuation Notice for conversion to, or continuation of, any
Eurodollar Rate Loans (or telephonic notice in lieu thereof) shall be
irrevocable on and after the related Interest Rate Determination Date, and
Borrower shall be bound to effect a conversion or continuation in accordance
therewith.

         2.7. DEFAULT INTEREST. Upon the occurrence and during the continuance
of an Event of Default of the type specified in Section 8.1(a), the principal
amount of all Loans, and, to the extent permitted by applicable law, any
interest payments on the Loans or any fees or other amounts owed hereunder not
paid when due, in each case whether at stated maturity, by notice of prepayment,
by acceleration or otherwise, shall thereafter bear interest (including
post-petition interest in any proceeding under the Bankruptcy Code or other
applicable bankruptcy laws) payable on demand at a rate that is 2% per annum in
excess of the interest rate otherwise payable hereunder with respect to the
applicable Loans (or, in the case of any such fees and other amounts, at a rate
which is 2% per annum in excess of the interest rate otherwise payable hereunder
for Base Rate Loans); provided, in the case of Eurodollar Rate Loans, upon the
expiration of the Interest Period in effect at the time any such increase in
interest rate is effective such Eurodollar Rate Loans shall thereupon become
Base Rate Loans and shall thereafter bear interest payable upon demand at a rate
which is 2% per annum in excess of the interest rate otherwise payable hereunder
for Base Rate Loans. Payment or acceptance of the increased rates of interest
provided for in this Section 2.7 is not a permitted alternative to timely
payment and shall not constitute a waiver of any Event of Default or otherwise
prejudice or limit any rights or remedies of Administrative Agent or any Lender.

         2.8. FEES. (a) Borrower agrees to pay to Lenders through Administrative
Agent a commitment fee equal to the average daily unused Commitment of such
Lender during the preceding quarter (or other period commencing with the date
upon which such Lender's Commitment was accepted) multiplied by the Applicable
Commitment Fee Percentage. All fees referred to in this Section 2.8(a) shall be
paid to Administrative Agent at its Principal Office and upon receipt,
Administrative Agent shall promptly distribute to each Lender its Pro Rata Share
thereof.

         (b) All fees referred to in Section 2.8(a) shall be calculated on the
basis of a 360-day year and the actual number of days elapsed and shall be
payable quarterly in arrears on March 15, June 15, September 15 and December 15
of each year during the Commitment Period, commencing on the first such date to
occur after the Closing Date, and on the Commitment Termination Date.


                                       35
<PAGE>   42

         (c) In addition to the foregoing fees, Borrower agrees to pay to Agents
such other fees in the amounts and at the times separately agreed upon by
Borrower and such Agents thereby.

         2.9.  SCHEDULED PAYMENTS/REDUCTIONS.

         (a) The total initial Commitments hereunder shall be permanently
reduced in the aggregate annual percentages set forth below in consecutive
quarterly installments (each, a "REDUCTION") on March 15, June 15, September 15
and December 15 of each year (each, a "REDUCTION DATE") occurring in each of the

                  (i) Any time and from time to time Borrower may prepay any
         Loans on any Business Day in whole or in part without premium (but
         subject to Section 2.16) in any aggregate minimum amount of $5,000,000
         and integral multiples of $1,000,000 in excess of that amount.

                  (ii) All such prepayments shall be made:

                           (1) upon not less than one Business Day's prior
                  written or telephonic notice, in the case of Base Rate Loans
                  and

                           (2) upon not less than three Business Days' prior
                  written or telephonic notice, in the case of Eurodollar Rate
                  Loans.

         in each case given to Administrative Agent by 12:00 noon (New York City
         time) on the date required and, if given by telephone, promptly
         confirmed in writing to Administrative Agent (and Administrative Agent
         will promptly transmit such telephonic or original notice by
         telefacsimile or telephone to each Lender). Upon the giving of any such
         notice, the principal


                                       36
<PAGE>   43

         amount of the Loans specified in such notice shall become due and
         payable on the prepayment date specified therein. Any such prepayment
         made pursuant to this Section 2.10(a) shall not reduce the Commitments
         unless Borrower has so requested in accordance with Section 2.10(b).

         (b)      Reductions.

                  (i) Borrower may, upon not less than three Business Days'
         prior written or telephonic notice confirmed in writing to
         Administrative Agent (which original written or telephonic notice
         Administrative Agent will promptly transmit by telefacsimile or
         telephone to each applicable Lender), at any time and from time to time
         terminate in whole or permanently reduce in part, without premium or
         penalty, the Commitments in an amount up to the amount by which the
         Commitments exceed the Total Utilization of Commitments at the time of
         such proposed termination or reduction plus the amount that Total
         Utilization of Commitments is prepaid pursuant to clause (a) above;
         provided, any such partial reduction of the Commitments shall be in an
         aggregate minimum amount of $5,000,000 and integral multiples of
         $1,000,000 in excess of that amount.

                  (ii) Borrower's notice to Administrative Agent shall designate
         the date (which shall be a Business Day) of such termination or
         reduction and the amount of any partial reduction, and such termination
         or reduction of the Commitments shall be effective on the date
         specified in Borrower's notice and shall reduce the Commitment of each
         Lender proportionately to its Pro Rata Share thereof.

         2.11. MANDATORY PREPAYMENTS/REDUCTIONS. (a) No later than the third
Business Day following the date of receipt by Company or any of its Subsidiaries
of any Net Asset Sale Proceeds, Borrower shall prepay the Loans and the
Commitments shall be permanently reduced in an aggregate amount equal to such
Net Asset Sale Proceeds; provided, so long as no Default or Event of Default
shall have occurred and be continuing, Company shall have the option, directly
or through one or more of its Subsidiaries, to invest such Net Asset Sale
Proceeds within two hundred seventy (270) days of receipt thereof in long term
productive assets of the general type used in the business of Company and its
Subsidiaries; provided further, pending any such investment all such Net Asset
Sale Proceeds shall be applied to prepay outstanding Loans (without a reduction
in Commitments).

         (b) No later than the third Business Day following the date of receipt
by Company or any of its Subsidiaries, or Administrative Agent as loss payee, of
any Net Insurance/Condemnation Proceeds, Borrower shall prepay the Loans and the
Commitments shall be permanently reduced in an aggregate amount equal to such
Net Insurance/Condemnation Proceeds; provided, so long as no Default or Event of
Default shall have occurred and be continuing, Company shall have the option,
directly or through one or more of its Subsidiaries to invest such Net
Insurance/Condemnation Proceeds within two hundred seventy (270) days of receipt
thereof in long term productive assets of the general type used in the business
of Company and its Subsidiaries, which investment may include the repair,
restoration or replacement of the applicable assets of Company or its
Subsidiaries;


                                       37
<PAGE>   44

provided, further, pending any such investment all such Net
Insurance/Condemnation Proceeds, as the case may be, shall be applied to prepay
outstanding Loans (without a reduction in Commitments).

         (c) In the event that there shall be Consolidated Excess Cash Flow for
any Fiscal Year (commencing with Fiscal Year 2003), Borrower shall, no later
than ninety (90) days after the end of such Fiscal Year, prepay the Loans and
the Commitments shall be permanently reduced in an aggregate amount equal to 75%
of such Consolidated Excess Cash Flow.

         (d) Borrower shall from time to time prepay the Loans to the extent
necessary so that the Total Utilization of Commitments shall not at any time
exceed the lesser of the (i) Commitments then in effect and (ii) Loan
Availability.

         (e) If at any time after the Initial Certified Conditions have been
previously satisfied but are no longer satisfied, Loan Availability shall be
immediately reduced to zero and all outstanding Loans shall be immediately
repaid, and if at any time after the Incremental Certified Conditions have been
previously satisfied but are no longer satisfied, outstanding Loans shall be
immediately repaid to the extent necessary such that Total Utilization of
Commitments shall not exceed Loan Availability.

         (f) On the date of receipt by Company or any of its Subsidiaries of any
Cash proceeds from the incurrence of Subordinated Indebtedness (other than with
respect to any such Indebtedness permitted to be incurred pursuant to Section
6.1(c)(i)), the Commitments shall be permanently reduced in an aggregate amount
equal to 100% of such proceeds, net of underwriting discounts and commissions
and other reasonable costs and expenses associated therewith, including
reasonable legal fees and expenses.

         (g) Concurrently with any prepayment of the Loans and/or reduction of
the Commitments pursuant to Sections 2.11(a) through 2.11(f), Borrower shall
deliver to Administrative Agent a certificate of an Authorized Officer
demonstrating the calculation of the amount of the applicable net proceeds or
Consolidated Excess Cash Flow, as the case may be. In the event that Borrower
shall subsequently determine that the actual amount received exceeded the amount
set forth in such certificate, Borrower shall promptly make an additional
prepayment of the Loans and/or the Commitments shall be permanently reduced) in
an amount equal to such excess, and Borrower shall concurrently therewith
deliver to Administrative Agent a certificate of an Authorized Officer
demonstrating the derivation such excess.

         2.12. APPLICATION OF PREPAYMENTS/REDUCTIONS. Any prepayment of Loans
shall be applied first to Base Rate Loans to the full extent thereof before
application to Eurodollar Rate Loans, in each case in a manner which minimizes
the amount of any payments required to be made by Borrower pursuant to Section
2.16(c).

         2.13. ALLOCATION OF CERTAIN PAYMENTS AND PROCEEDS. If an Event of
Default shall have occurred and not otherwise be waived, and the maturity of the
Obligations shall have been


                                       38
<PAGE>   45

accelerated pursuant to Section 8.1, all payments or proceeds received by Agents
hereunder in respect of any of the Obligations, shall be applied by Agents in
the following order:

                  first, amounts due to the Agents pursuant to Section 10.2;

                  second, amounts due to Lenders, if any, pursuant to Sections
         2.16, 2.17 or 2.18, to be applied for the ratable benefit of Lenders
         without distinction or preference as among them;

                  third, amounts due to Lenders pursuant to Sections 2.8 and
         10.2, to be applied for the ratable benefit of Lenders without
         distinction or preference as among them;

                  fourth, amounts due to Agents pursuant to Section 2.8, to be
         applied in accordance therewith;

                  fifth, payments of interest on Loans, without distinction or
         preference as among them;

                  sixth, payments of principal on Loans, and all Obligations
         then payable to any Lender Counterparty pursuant to a Hedge Agreement
         permitted hereby, to be applied for the ratable benefit of Lenders and
         such Lender Counterparties, without distinction or preference as among
         them;

                  seventh, amounts due to Indemnitees pursuant to Section 10.3,
         to be applied for the ratable benefit thereof;

                  eighth, payments of all other Obligations due under any of the
         Credit Documents, if any, to be applied for the ratable benefit of
         Lenders and Agents; and

                  ninth, any surplus remaining after application as provided for
         herein, to Borrower or as otherwise may be required by applicable law.

         2.14. GENERAL PROVISIONS REGARDING PAYMENTS. (a) All payments by
Borrower of principal, interest, fees and other Obligations shall be made in
Dollars in same day funds, without defense, setoff or counterclaim, free of any
restriction or condition, and delivered to Administrative Agent not later than
12:00 Noon (New York City time) on the date due at the Administrative Agent's
Principal Office for the account of Lenders; funds received by Administrative
Agent after that time on such due date shall be deemed to have been paid by
Borrower on the next succeeding Business Day.

         (b) All payments in respect of the principal amount of any Loan shall
include payment of accrued interest on the principal amount being repaid or
prepaid, and all such payments (and, in any event, any payments in respect of
any Loan on a date when interest is due and payable with respect to such Loan)
shall be applied to the payment of interest before application to principal.


                                       39
<PAGE>   46

         (c) Administrative Agent shall promptly distribute to each Lender at
such address as such Lender shall indicate in writing, such Lender's applicable
Pro Rata Share of all payments and prepayments of principal and interest due
hereunder, together with all other amounts due thereto, including, without
limitation, all fees payable with respect thereto, to the extent received by
Administrative Agent.

         (d) Notwithstanding the foregoing provisions hereof, if any
Conversion/Continuation Notice is withdrawn as to any Affected Lender or if any
Affected Lender makes Base Rate Loans in lieu of its Pro Rata Share of any
Eurodollar Rate Loans, Administrative Agent shall give effect thereto in
apportioning payments received thereafter.

         (e) Subject to the provisos set forth in the definition of "INTEREST
PERIOD", whenever any payment to be made hereunder shall be stated to be due on
a day that is not a Business Day, such payment shall be made on the next
succeeding Business Day and such extension of time shall be included in the
computation of the payment of interest hereunder or of the Commitment fees
hereunder, as the case may be.

         (f) Borrower hereby authorizes Administrative Agent to charge
Borrower's or Company's accounts with Administrative Agent in order to cause
timely payment to be made to Administrative Agent of all principal, interest,
fees and expenses due hereunder (subject to sufficient funds being available in
its accounts for that purpose).

         (g) Administrative Agent shall deem any payment by or on behalf of
Borrower hereunder that is not made in same day funds prior to 12:00 noon (New
York City time) on or before the due date to be a non-conforming payment. Any
such payment shall not be deemed to have been received by Administrative Agent
until the later of (i) the time such funds become available funds, and (ii) the
applicable next Business Day. Administrative Agent shall give prompt telephonic
notice to Borrower and each applicable Lender (confirmed in writing) if any
payment is non-conforming. Any non-conforming payment may constitute or become a
Default or Event of Default in accordance with the terms of Section 8.1(a).
Interest shall continue to accrue on any principal as to which a non-conforming
payment is made until such funds become available funds (but in no event less
than the period from the date of such payment to the next succeeding applicable
Business Day) at the rate determined pursuant to Section 2.7 from the date such
amount was due and payable until the date such amount is paid in full.

         2.15. RATABLE SHARING. Lenders hereby agree among themselves that if
any of them shall, whether by voluntary payment (other than a voluntary
prepayment of Loans made and applied in accordance with the terms hereof), by
realization upon security, through the exercise of any right of set-off or
banker's lien, by counterclaim or cross action or by the enforcement of any
right under the Credit Documents or otherwise, or as adequate protection of a
deposit treated as cash collateral under the Bankruptcy Code, receive payment or
reduction of a proportion of the aggregate amount of principal, interest, fees
and other amounts then due and owing to such Lender hereunder or under the other
Credit Documents (collectively, the "AGGREGATE AMOUNTS DUE" to such Lender)
which


                                       40
<PAGE>   47

is greater than the proportion received by any other Lender in respect of the
Aggregate Amounts Due to such other Lender, then the Lender receiving such
proportionately greater payment shall (a) notify Administrative Agent and each
other Lender of the receipt of such payment and (b) apply a portion of such
payment to purchase participations (which it shall be deemed to have purchased
from each seller of a participation simultaneously upon the receipt by such
seller of its portion of such payment) in the Aggregate Amounts Due to the other
Lenders so that all such recoveries of Aggregate Amounts Due shall be shared by
all Lenders in proportion to the Aggregate Amounts Due to them; provided, if all
or part of such proportionately greater payment received by such purchasing
Lender is thereafter recovered from such Lender upon the bankruptcy or
reorganization of Borrower or otherwise, those purchases shall be rescinded and
the purchase prices paid for such participations shall be returned to such
purchasing Lender ratably to the extent of such recovery, but without interest.
Borrower expressly consents to the foregoing arrangement and agrees that any
holder of a participation so purchased may exercise any and all rights of
banker's lien, set-off or counterclaim with respect to any and all monies owing
by Borrower to that holder with respect thereto as fully as if that holder were
owed the amount of the participation held by that holder.

         2.16. MAKING OR MAINTAINING EURODOLLAR RATE LOANS. (a) In the event
that Administrative Agent shall have determined (which determination shall be
final and conclusive and binding upon all parties hereto), on any Interest Rate
Determination Date with respect to any Eurodollar Rate Loans, that by reason of
circumstances affecting the London interbank market adequate and fair means do
not exist for ascertaining the interest rate applicable to such Loans on the
basis provided for in the definition of Adjusted Eurodollar Rate, Administrative
Agent shall on such date give notice (by telefacsimile or by telephone confirmed
in writing) to Borrower and each Lender of such determination, whereupon (i) no
Loans may be made as, or converted to, Eurodollar Rate Loans until such time as
Administrative Agent notifies Borrower and Lenders that the circumstances giving
rise to such notice no longer exist, and (ii) any Funding Notice or
Conversion/Continuation Notice given by Borrower with respect to the Loans in
respect of which such determination was made shall be deemed to be rescinded by
Borrower.

         (b) In the event that on any date any Lender shall have determined
(which determination shall be final and conclusive and binding upon all parties
hereto but shall be made only after consultation with Borrower and
Administrative Agent) that the making, maintaining or continuation of its
Eurodollar Rate Loans (i) has become unlawful as a result of compliance by such
Lender in good faith with any law, treaty, governmental rule, regulation,
guideline or order (or would conflict with any such treaty, governmental rule,
regulation, guideline or order not having the force of law even though the
failure to comply therewith would not be unlawful), or (ii) has become
impracticable, as a result of contingencies occurring after the date hereof
which materially and adversely affect the London interbank market or the
position of such Lender in that market, then, and in any such event, such Lender
shall be an "AFFECTED LENDER" and it shall on that day give notice (by
telefacsimile or by telephone confirmed in writing) to Borrower and
Administrative Agent of such determination (which notice Administrative Agent
shall promptly transmit to each other Lender). Thereafter (1) the obligation of
the Affected Lender to make Loans as, or to convert Loans to, Eurodollar Rate
Loans shall be suspended until such notice shall be withdrawn by the Affected


                                       41
<PAGE>   48

Lender, (2) to the extent such determination by the Affected Lender relates to a
Eurodollar Rate Loan then being requested by Borrower pursuant to a Funding
Notice or a Conversion/Continuation Notice, the Affected Lender shall make such
Loan as (or convert such Loan to, as the case may be) a Base Rate Loan, (3) the
Affected Lender's obligation to maintain its outstanding Eurodollar Rate Loans
(the "AFFECTED LOANS") shall be terminated at the earlier to occur of the
expiration of the Interest Period then in effect with respect to the Affected
Loans or when required by law, and (4) the Affected Loans shall automatically
convert into Base Rate Loans on the date of such termination. Notwithstanding
the foregoing, to the extent a determination by an Affected Lender as described
above relates to a Eurodollar Rate Loan then being requested by Borrower
pursuant to a Funding Notice or a Conversion/Continuation Notice, Borrower shall
have the option, subject to the provisions of Section 2.17(c), to rescind such
Funding Notice or Conversion/Continuation Notice as to all Lenders by giving
notice (by telefacsimile or by telephone confirmed in writing) to Administrative
Agent of such rescission on the date on which the Affected Lender gives notice
of its determination as described above (which notice of rescission
Administrative Agent shall promptly transmit to each other Lender). Except as
provided in the immediately preceding sentence, nothing in this Section 2.16(b)
shall affect the obligation of any Lender other than an Affected Lender to make
or maintain Loans as, or to convert Loans to, Eurodollar Rate Loans in
accordance with the terms hereof.

         (c) Borrower shall compensate each Lender, upon written request by such
Lender (which request shall set forth the basis for requesting such amounts),
for all reasonable losses, expenses and liabilities (including any interest paid
by such Lender to lenders of funds borrowed by it to make or carry its
Eurodollar Rate Loans and any loss, expense or liability sustained by such
Lender in connection with the liquidation or re-employment of such funds but
excluding loss of anticipated profits) which such Lender may sustain: (i) if for
any reason (other than a default by such Lender) a borrowing of any Eurodollar
Rate Loan does not occur on a date specified therefor in a Funding Notice or a
telephonic request for borrowing, or a conversion to or continuation of any
Eurodollar Rate Loan does not occur on a date specified therefor in a
Conversion/Continuation Notice or a telephonic request for conversion or
continuation; (ii) if any prepayment or other principal payment or any
conversion of any of its Eurodollar Rate Loans occurs on a date prior to the
last day of an Interest Period applicable to that Loan; (iii) if any prepayment
of any of its Eurodollar Rate Loans is not made on any date specified in a
notice of prepayment given by Borrower; or (iv) as a consequence of any other
default by Borrower in the repayment of its Eurodollar Rate Loans when required
by the terms hereof.

         (d) Any Lender may make, carry or transfer Eurodollar Rate Loans at,
to, or for the account of any of its branch offices or the office of an
Affiliate of such Lender.

         (e) Calculation of all amounts payable to a Lender under this Section
2.16 and under Section 2.17 shall be made as though such Lender had actually
funded each of its relevant Eurodollar Rate Loans through the purchase of a
Eurodollar deposit bearing interest at the rate obtained pursuant to clause (i)
of the definition of Adjusted Eurodollar Rate in an amount equal to the amount
of such Eurodollar Rate Loan and having a maturity comparable to the relevant
Interest Period and through


                                       42
<PAGE>   49

the transfer of such Eurodollar deposit from an offshore office of such Lender
to a domestic office of such Lender in the United States ; provided, each Lender
may fund each of its Eurodollar Rate Loans in any manner it sees fit and the
foregoing assumptions shall be utilized only for the purposes of calculating
amounts payable under this Section 2.16 and under Section 2.17.

         2.17. INCREASED COSTS; CAPITAL ADEQUACY. (a) Subject to the provisions
of Section 2.18 (which shall be controlling with respect to the matters covered
thereby), in the event that any Lender shall determine (which determination
shall, absent manifest error, be final and conclusive and binding upon all
parties hereto) that any law, treaty or governmental rule, regulation or order,
or any change therein or in the interpretation, administration or application
thereof (including the introduction of any new law, treaty or governmental rule,
regulation or order), or any determination of a court or governmental authority,
in each case that becomes effective after the date hereof, or compliance by such
Lender with any guideline, request or directive issued or made after the date
hereof by any central bank or other governmental or quasi-governmental authority
(whether or not having the force of law): (i) subjects such Lender (or its
applicable lending office) to any additional Tax (other than any Tax on the
overall net income of such Lender) with respect to this Agreement or any of its
obligations hereunder or any payments to such Lender (or its applicable lending
office) of principal, interest, fees or any other amount payable hereunder; (ii)
imposes, modifies or holds applicable any reserve (including any marginal,
emergency, supplemental, special or other reserve), special deposit, compulsory
loan, FDIC insurance or similar requirement against assets held by, or deposits
or other liabilities in or for the account of, or advances or loans by, or other
credit extended by, or any other acquisition of funds by, any office of such
Lender (other than any such reserve or other requirements with respect to
Eurodollar Rate Loans that are reflected in the definition of Adjusted
Eurodollar Rate); or (iii) imposes any other condition (other than with respect
to a Tax matter) on or affecting such Lender (or its applicable lending office)
or its obligations hereunder or the London interbank market; and the result of
any of the foregoing is to increase the cost to such Lender of agreeing to make,
making or maintaining Loans hereunder or to reduce any amount received or
receivable by such Lender (or its applicable lending office) with respect
thereto; then, in any such case, Borrower shall pay to such Lender within 10
days upon receipt of the statement referred to in the next sentence, such
additional amount or amounts (in the form of an increased rate of, or a
different method of calculating, interest or otherwise as such Lender in its
sole discretion shall determine) as may be necessary to compensate such Lender
for any such increased cost or reduction in amounts received or receivable
hereunder; provided that Borrower shall not be obligated to reimburse any Lender
for such increase or reduction for any period 180 days prior to such Lender
providing notice if such Lender was aware of the circumstances that existed
which would cause such increase or reduction during such 180 day period. Such
Lender shall deliver to Borrower (with a copy to Administrative Agent) a written
statement, setting forth in reasonable detail the basis for calculating the
additional amounts owed to such Lender under this Section 2.17(a), which
statement shall be conclusive and binding upon all parties hereto absent
manifest error.

         (b) In the event that any Lender shall have determined that the
adoption, effectiveness, phase-in or applicability after the date hereof of any
law, rule or regulation (or any provision thereof) regarding capital adequacy,
or any change therein or in the interpretation or administration thereof


                                       43
<PAGE>   50

by any governmental authority, central bank or comparable agency charged with
the interpretation or administration thereof, or compliance by any Lender (or
its applicable lending office) with any guideline, request or directive
regarding capital adequacy (whether or not having the force of law) of any such
governmental authority, central bank or comparable agency, 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, or with reference to,
such Lender's Loans or Commitments or other obligations hereunder with respect
to the Loans to a level below that which such Lender or such controlling
corporation could have achieved but for such adoption, effectiveness, phase-in,
applicability, change or compliance (taking into consideration the policies of
such Lender or such controlling corporation with regard to capital adequacy),
then from time to time, within 10 days after receipt by Borrower from such
Lender of the statement referred to in the next sentence, Borrower shall pay to
such Lender such additional amount or amounts as will compensate such Lender or
such controlling corporation on an after-tax basis for such reduction; provided
that Borrower shall not be obligated to reimburse any Lender for such increase
or reduction for any period 180 days prior to such Lender providing notice if
such Lender was aware of the circumstances that existed which would cause such
increase or reduction during such 180 day period. Such Lender shall deliver to
Borrower (with a copy to Administrative Agent) a written statement, setting
forth in reasonable detail the basis of the calculation of such additional
amounts, which statement shall be conclusive and binding upon all parties hereto
absent manifest error.

         2.18. TAXES; WITHHOLDING, ETC. (a) All sums payable by any Credit Party
hereunder and the other Credit Documents shall (except to the extent required by
law) be paid free and clear of, and without any deduction or withholding on
account of, any Tax (other than a Tax on the overall net income of any Lender)
imposed, levied, collected, withheld or assessed by or within the United States
or any political subdivision in or of the United States or any other
jurisdiction from or to which a payment is made by or on behalf of any Credit
Party or by any federation or organization of which the United States or any
such jurisdiction is a member at the time of payment.

         (b) If any Credit Party or any other Person is required by law to make
any deduction or withholding on account of any such Tax from any sum paid or
payable by any Credit Party to Administrative Agent or any Lender under any of
the Credit Documents: (i) Borrower shall notify Administrative Agent of any such
requirement or any change in any such requirement as soon as Borrower becomes
aware of it; (ii) Borrower shall pay any such Tax before the date on which
penalties attach thereto, such payment to be made (if the liability to pay is
imposed on any Credit Party) for its own account or (if that liability is
imposed on Administrative Agent or such Lender, as the case may be) on behalf of
and in the name of Administrative Agent or such Lender; (iii) the sum payable by
such Credit Party in respect of which the relevant deduction, withholding or
payment is required shall be increased to the extent necessary to ensure that,
after the making of that deduction, withholding or payment, Administrative Agent
or such Lender, as the case may be, receives on the due date a net sum equal to
what it would have received had no such deduction, withholding or payment been
required or made; and (iv) within thirty (30) days after paying any sum from
which it is required by law to make any deduction or withholding, and within
thirty (30) days after the due date of payment of any Tax which it is required
by clause (ii) above to pay, Borrower


                                       44
<PAGE>   51

shall deliver to Administrative Agent evidence satisfactory to the other
affected parties of such deduction, withholding or payment and of the remittance
thereof to the relevant taxing or other authority; provided, no such additional
amount shall be required to be paid to any Lender under clause (iii) above
except to the extent that any change after the date hereof (in the case of each
Lender listed on the signature pages hereof on the Closing Date) or after the
effective date of the Assignment Agreement pursuant to which such Lender became
a Lender (in the case of each other Lender) in any such requirement for a
deduction, withholding or payment as is mentioned therein shall result in an
increase in the rate of such deduction, withholding or payment from that in
effect at the date hereof or at the date of such Assignment Agreement, as the
case may be, in respect of payments to such Lender.

         (c) Each Lender that is organized under the laws of any jurisdiction
other than the United States or any state or other political subdivision thereof
(a "NON-US LENDER") shall deliver to Administrative Agent for transmission to
Borrower, on or prior to the Closing Date (in the case of each Lender listed on
the signature pages hereof on the Closing Date) or on or prior to the date of
the Assignment Agreement pursuant to which it becomes a Lender (in the case of
each other Lender), and at such other times as may be necessary in the
determination of Borrower or Administrative Agent (each in the reasonable
exercise of its discretion), (i) two original copies of Internal Revenue Service
Form 1001 or 4224 (or any successor forms, including Form W-8BEN or W-8ECI),
properly completed and duly executed by such Lender, together with any other
certificate or statement of exemption required under the Internal Revenue Code
or the regulations issued thereunder to establish that such Lender is not
subject to deduction or withholding of United States federal income tax with
respect to any payments to such Lender of principal, interest, fees or other
amounts payable under any of the Credit Documents, or (ii) if such Lender is not
a "bank" or other Person described in Section 881(c)(3) of the Internal Revenue
Code and cannot deliver either Internal Revenue Service Form 1001 or 4224
pursuant to clause (i) above, a Certificate re Non-Bank Status together with two
original copies of Internal Revenue Service Form W-8 (or any successor form),
properly completed and duly executed by such Lender, together with any other
certificate or statement of exemption required under the Internal Revenue Code
or the regulations issued thereunder to establish that such Lender is not
subject to deduction or withholding of United States federal income tax with
respect to any payments to such Lender of interest payable under any of the
Credit Documents. Each Lender required to deliver any forms, certificates or
other evidence with respect to United States federal income tax withholding
matters pursuant to this Section 2.18(c) hereby agrees, from time to time after
the initial delivery by such Lender of such forms, certificates or other
evidence, whenever a lapse in time or change in circumstances renders such
forms, certificates or other evidence obsolete or inaccurate in any material
respect, that such Lender shall promptly deliver to Administrative Agent for
transmission to Borrower two new original copies of Internal Revenue Service
Form 1001 or 4224, or a Certificate re Non-Bank Status and two original copies
of Internal Revenue Service Form W-8, as the case may be, properly completed and
duly executed by such Lender, together with any other certificate or statement
of exemption required in order to confirm or establish that such Lender is not
subject to deduction or withholding of United States federal income tax with
respect to payments to such Lender under the Credit Documents, or notify
Administrative Agent and Borrower of its inability to deliver any such forms,
certificates or other evidence. Borrower shall


                                       45
<PAGE>   52

not be required to pay any additional amount under Section 2.18(b)(iii) if such
Lender shall have failed (1) to deliver the forms, certificates or other
evidence referred to in the second sentence of this Section 2.18(c), or to
notify Administrative Agent and Borrower of its inability to deliver any such
forms, certificates or other evidence, as the case may be; provided, if such
Lender shall have satisfied the requirements of the first sentence of this
Section 2.18(c) on the Closing Date or on the date of the Assignment Agreement
pursuant to which it became a Lender, as applicable, nothing in this last
sentence of Section 2.18(c) shall relieve Borrower of its obligation to pay any
additional amounts pursuant to Section 2.18(a) in the event that, as a result of
any change in any applicable law, treaty or governmental rule, regulation or
order, or any change in the interpretation, administration or application
thereof, such Lender is no longer properly entitled to deliver forms,
certificates or other evidence at a subsequent date establishing the fact that
such Lender is not subject to withholding as described herein.

         (d) If any Tax is refunded to Administrative Agent, it will pay such
refund to Borrower to the extent Administrative Agent determines in its sole
discretion that such refund is attributable to any Tax paid by Borrower and to
the extent Borrower has previously indemnified the Administrative Agent therefor
pursuant to this Section 2.18, net of expenses and without interest except any
interest (net of taxes) included in such refund. Borrower shall return such
refund (together with any taxes, penalties or other charges) in the event any
Agent or any Lender is required to repay such refund. Notwithstanding the
foregoing, nothing in this Section 2.18 shall be construed to (i) entitle
Borrower or any other Persons to (A) any information determined by any Agent or
Lender, in each case, in its sole discretion, to be confidential or proprietary
information of such Agent or Lender, (B) any tax or financial information of
such Agent or Lender, or (C) inspect or review any books and records of any
Agent or Lender, or (ii) interfere with the rights of any Agent or Lender to
conduct its fiscal or tax affairs in such matter as it deems fit. A certificate
as to the amount of such payment or liability delivered to Borrower by
Administrative Agent on its own behalf or on behalf of any Lender or Agent shall
be conclusive absent manifest error.

         2.19. OBLIGATION TO MITIGATE. Each Lender agrees that, as promptly as
practicable after the officer of such Lender responsible for administering its
Loans becomes aware of the occurrence of an event or the existence of a
condition that would cause such Lender to become an Affected Lender or that
would entitle such Lender to receive payments under Section 2.16, 2.17 or 2.18,
it will, to the extent not inconsistent with the internal policies of such
Lender and any applicable legal or regulatory restrictions, use reasonable
efforts (a) to make, issue, fund or maintain its Commitment or Loans, including
any Affected Loans, through another office of such Lender, or (b) take such
other measures as such Lender may deem reasonable, if as a result thereof the
circumstances which would cause such Lender to be an Affected Lender would cease
to exist or the additional amounts which would otherwise be required to be paid
to such Lender pursuant to Section 2.16, 2.17 or 2.18 would be materially
reduced and if, as determined by such Lender in its sole discretion, the making,
issuing, funding or maintaining of such Commitments or Loans through such other
office or in accordance with such other measures, as the case may be, would not
otherwise adversely affect such Commitments or Loans or the interests of such
Lender; provided, such Lender will not be obligated


                                       46
<PAGE>   53

to utilize such other office pursuant to this Section 2.19 unless Borrower
agrees to pay all incremental expenses incurred by such Lender as a result of
utilizing such other office as described in clause (i) above. A certificate as
to the amount of any such expenses payable by Borrower pursuant to this Section
2.19 (setting forth in reasonable detail the basis for requesting such amount)
submitted by such Lender to Borrower (with a copy to Administrative Agent) shall
be conclusive absent manifest error.

         2.20. DEFAULTING LENDERS. Anything contained herein to the contrary
notwithstanding, in the event that any Lender defaults (a "DEFAULTING LENDER")
in its obligation to fund (a "FUNDING DEFAULT") any Loan (a "DEFAULTED LOAN"),
then (a) during such period when such default is continuing with respect to such
Defaulting Lender (the "DEFAULT PERIOD"), such Defaulting Lender shall be deemed
not to be a "Lender" for purposes of voting on any matters (including the
granting of any consents or waivers) with respect to any of the Credit
Documents; (b) to the extent permitted by applicable law, until such time as
such unfunded amount with respect to such Defaulting Lender shall have been
reduced to zero, (i) any voluntary prepayment of the Loans shall, if Borrower so
directs at the time of making such voluntary prepayment, be applied to the Loans
of other Lenders as if such Defaulting Lender had no Loans outstanding and the
Credit Exposure of such Defaulting Lender were zero, and (ii) any mandatory
prepayment of the Loans shall, if Borrower so directs at the time of making such
mandatory prepayment, be applied to the Loans of other Lenders (but not to the
Loans of such Defaulting Lender) as if such Defaulting Lender had funded all
Defaulted Loans of such Defaulting Lender, it being understood and agreed that
Borrower shall be entitled to retain any portion of any mandatory prepayment of
the Loans that is not paid to such Defaulting Lender solely as a result of the
operation of the provisions of this clause (b); (c) such Defaulting Lender's
Commitment and outstanding Loans shall be excluded for purposes of calculating
the commitment fee payable to Lenders in respect of any day during any Default
Period with respect to such Defaulting Lender, and such Defaulting Lender shall
not be entitled to receive any commitment fee pursuant to Section 2.8 with
respect to such Defaulting Lender's Commitment in respect of any Default Period
with respect to such Defaulting Lender; and (d) the Total Utilization of
Commitments as at any date of determination shall be calculated as if such
Defaulting Lender had funded all Defaulted Loans of such Defaulting Lender. No
Commitment of any Lender shall be increased or otherwise affected, and, except
as otherwise expressly provided in this Section 2.20, performance by Borrower of
its obligations hereunder and the other Credit Documents shall not be excused or
otherwise modified as a result of any Funding Default or the operation of this
Section 2.20. The rights and remedies against a Defaulting Lender under this
Section 2.20 are in addition to other rights and remedies which Borrower may
have against such Defaulting Lender with respect to any Funding Default and
which Administrative Agent or any Lender may have against such Defaulting Lender
with respect to any Funding Default.

         2.21. REMOVAL OR REPLACEMENT OF A LENDER. Anything contained herein to
the contrary notwithstanding, in the event that: (a) any Lender (an
"INCREASED-COST LENDER") shall give notice to Borrower that such Lender is an
Affected Lender or that such Lender is entitled to receive payments under
Section 2.16, 2.17 or 2.18, the circumstances which have caused such Lender to
be an Affected Lender or which entitle such Lender to receive such payments
shall remain in effect, and


                                       47
<PAGE>   54

such Lender shall fail to withdraw such notice within five Business Days after
Borrower's request for such withdrawal; or (b) any Lender shall become a
Defaulting Lender, the Default Period for such Defaulting Lender shall remain in
effect, and such Defaulting Lender shall fail to cure the default as a result of
which it has become a Defaulting Lender within five Business Days after
Borrower's request that it cure such default; or (c) in connection with any
proposed amendment, modification, termination, waiver or consent with respect to
any of the provisions hereof as contemplated by Section 10.5(b), the consent of
Requisite Lenders shall have been obtained but the consent of one or more of
such other Lenders (each a "NON-CONSENTING LENDER") whose consent is required
shall not have been obtained, and the failure to obtain Non-Consenting Lenders'
consents does not result solely from the exercise of Non-Consenting Lenders'
rights (and the withholding of any required consents by Non-Consenting Lenders)
pursuant to the proviso to Section 10.5(c)(i); then, with respect to each such
Increased-Cost Lender, Defaulting Lender or Non-Consenting Lender (the
"TERMINATED LENDER"), Borrower may, by giving written notice to Administrative
Agent and any Terminated Lender of its election to do so, elect to:

                  (A) cause such Terminated Lender (and such Terminated Lender
         hereby irrevocably agrees) to assign its outstanding Loans and its
         Commitments, if any, in full to one or more Eligible Assignees (each a
         "REPLACEMENT LENDER") in accordance with the provisions of Section 10.6
         and Terminated Lender shall pay any fees payable thereunder in
         connection with such assignment; provided, (1) on the date of such
         assignment, Borrower shall pay any amounts payable to such Terminated
         Lender pursuant to Section 2.16(c), 2.17 or 2.18 or otherwise as if it
         were a prepayment, and shall pay the assignment fee specified in
         Section 10.6(d) and (2) in the event such Terminated Lender is a
         Non-Consenting Lender, each Replacement Lender shall consent, at the
         time of such assignment, to each matter in respect of which such
         Terminated Lender was a Non-Consenting Lender; provided, Borrower may
         not make such election with respect to any Non-Consenting Lender unless
         Borrower also makes such election with respect to each other Terminated
         Lender which is a Non-Consenting Lender; and upon the prepayment of all
         amounts due and owing to any Terminated Lender pursuant to Section
         2.16(c), 2.17 and 2.18 and the assignment of such Terminated Lender's
         Commitments, if any, and such Terminated Lender shall no longer
         constitute a "Lender" for purposes hereof; provided, any rights of such
         Terminated Lender to indemnification hereunder shall survive as to such
         Terminated Lender; or

                  (B) (1) terminate the Commitment of such Terminated Lender
         upon receipt by such Terminated Lender of such notice and (2) prepay on
         the date of such termination any outstanding Loans, if any, made by
         such Terminated Lender, together with accrued and unpaid interest
         thereon and any other amounts payable to such Terminated Lender
         hereunder pursuant to Section 2.16(c), 2.17 and 2.18 or otherwise;
         provided that, in the event such Terminated Lender has any Loans
         outstanding at the time of such termination, the written consent of
         Administrative Agent and all Lenders (which consent shall not be
         unreasonably withheld or delayed) shall be required in order for
         Borrower to make such election; and provided further that Borrower may
         not make such election with respect to any


                                       48
<PAGE>   55

         NonConsenting Lender unless Borrower also makes such election with
         respect to each other Terminated Lender which is a Non-Consenting
         Lender.

SECTION 4.  REPRESENTATIONS AND WARRANTIES

         In order to induce Lenders to enter into this Agreement and to make
each Loan to be made thereby, each Credit Party represents and warrants to each
Lender on the Closing Date and on each Credit Date, that the following
statements are true, correct and complete:

         4.1. ORGANIZATION; POWERS; QUALIFICATION. Each of Company and its
Subsidiaries (a) is duly organized, validly existing and in good standing under
the laws of its jurisdiction of organization as identified in Schedule 4.1, (b)
has all requisite power and authority to own and operate its properties, to
carry on its business as now conducted and as proposed to be conducted, to enter
into the Credit Documents to which it is a party and to carry out the
transactions contemplated thereby, and (c) is qualified to do business and in
good standing in every jurisdiction where its assets are located and wherever
necessary to carry out its business and operations, except in jurisdictions
where the failure to be so qualified or in good standing has not had, and could
not be reasonably expected to have, a Material Adverse Effect. Schedule 4.1, as
may be amended pursuant to Section 5.1(b) or (c), correctly sets forth the
ownership interest of Company and each of its Subsidiaries in their respective
Subsidiaries.

         4.2. AUTHORIZATION OF CREDIT DOCUMENTS; NO CONFLICT. The execution,
delivery and performance of the Credit Documents have been duly authorized by
all necessary action on the part of each Credit Party that is a party thereto.
Except as set forth on Schedule 4.2, the execution, delivery and performance by
Credit Parties of the Credit Documents to which they are parties and the
consummation of the transactions contemplated by the Credit Documents do not and
will not (a) violate any provision of any law or any governmental rule or
regulation applicable to Company or any of its Subsidiaries, any of the
Organizational Documents of Company or any of its Subsidiaries, or any order,
judgment or decree of any court or other agency of government binding on Company
or any of its Subsidiaries; (b) conflict with, result in a breach of or
constitute (with due notice or lapse of time or both) a default under any
Contractual Obligation of Company or any of its Subsidiaries; (c) result in or
require the creation or imposition of any Lien upon any of the properties or
assets of Company or any of its Subsidiaries (other than any Liens created under

of any Person under any Contractual Obligation of Company or any of its
Subsidiaries.

         4.3. GOVERNMENTAL CONSENTS. The execution, delivery and performance by
Credit Parties of the Credit Documents to which they are parties and the
consummation of the transactions contemplated by the Credit Documents do not and
will not require any registration with, consent or approval of, or notice to, or
other action to, with or by, any Governmental Authority except as otherwise set
forth on Schedule 4.3, and except for filings and recordings with respect to the
Collateral to be made, or otherwise delivered to Administrative Agent, as of the
Closing Date.

         4.4. BINDING OBLIGATION. Each Credit Document has been duly executed
and delivered by each Credit Party that is a party thereto and is the legally
valid and binding obligation of such Credit Party, enforceable against such
Credit Party in accordance with its respective terms, except as may be limited
by bankruptcy, insolvency, reorganization, moratorium or similar laws relating
to or limiting creditors' rights generally or by equitable principles relating
to enforceability.

         4.5. HISTORICAL FINANCIAL STATEMENTS; PROJECTIONS. The Historical
Financial Statements were prepared in conformity with GAAP and fairly present,
in all material respects, the financial position, on a consolidated basis, of
the Persons described in such financial statements as at the respective dates
thereof and the results of operations and cash flows, on a consolidated basis,
of the entities described therein for each of the periods then ended, subject,
in the case of any such unaudited financial statements, to changes resulting
from audit and normal year-end adjustments. On the Closing Date, neither Company
nor any of its Subsidiaries has any contingent liability or liability for taxes,
long-term lease or unusual forward or long-term commitment that is not reflected
in the Historical Financial Statements or the notes thereto and which in
accordance with GAAP would be required to be shown thereon and which in any such
case is material in relation to the business, operations, properties, assets,
condition (financial or otherwise) or prospects of Company and any of its
Subsidiaries taken as a whole. On and as of the Closing Date, the financial
forecast of Company and its Subsidiaries delivered pursuant to Section 3.1(i)
(the "PROJECTIONS") are based on good faith estimates and assumptions made by
the management of Company; provided, the Projections are not to be viewed as
facts and that actual results during the period or periods covered by the
Projections may differ from such Projections and that the differences may be
material; provided further, as of the Closing Date, management of Company
believed that the Projections were reasonable and attainable.

         4.6. NO MATERIAL ADVERSE CHANGE; NO RESTRICTED JUNIOR PAYMENTS. Since
December 31, 1998, no event or change has occurred that has caused or evidences,
either in any case or in the aggregate, a Material Adverse Effect, and neither
Company nor any of its Subsidiaries has directly or indirectly declared,
ordered, paid or made, or set apart any sum or property for, any Restricted
Junior Payment or agreed to do so except as permitted pursuant to Section 6.4.

         4.7. ADVERSE PROCEEDINGS, ETC. Except as set forth on Schedule 4.7,
there are no Adverse Proceedings, individually or in the aggregate, that could
reasonably be expected to have a Material Adverse Effect. Neither Company nor
any of its Subsidiaries (a) is in violation of any applicable laws (including
Environmental Laws) that, individually or in the aggregate, could reasonably be
expected to have a Material Adverse Effect, or (b) is subject to or in default
with respect to any final


                                       54
<PAGE>   61

judgments, writs, injunctions, decrees, rules or regulations of any court or any
federal, state, municipal or other governmental department, commission, board,
bureau, agency or instrumentality, domestic or foreign, that, individually or in
the aggregate, could reasonably be expected to have a Material Adverse Effect.

         4.8. PAYMENT OF TAXES. Except as otherwise permitted under Section 5.3,
all tax returns and reports of Company and its Subsidiaries required to be filed
by any of them have been timely filed, and all taxes shown on such tax returns
to be due and payable and all assessments, fees and other governmental charges
upon Company and its Subsidiaries and upon their respective properties, assets,
income, businesses and franchises which are due and payable have been paid when
due and payable, except where the failure to do so could not reasonably be
expected to have a Material Adverse Effect. Company knows of no proposed tax
assessment against Company or any of its Subsidiaries which is not being
actively contested by Company or such Subsidiary in good faith and by
appropriate proceedings; provided, such reserves or other appropriate
provisions, if any, as shall be required in conformity with GAAP shall have been
made or provided therefor.

         4.9. TITLE TO PROPERTIES. (a) Company and its Subsidiaries have (i)
good, sufficient and legal title to (in the case of fee interests in real
property), (ii) valid leasehold interests in (in the case of leasehold interests
in real or personal property), or (iii) good title to (in the case of all other
personal property), all of their respective properties and assets reflected in
the Historical Financial Statements referred to in Section 4.5 and in the most
recent financial statements delivered pursuant to Section 5.1, in each case
except for (1) assets disposed of since the date of such financial statements in
the ordinary course of business or as otherwise permitted under Section 6.8 and
(2) minor defects in title that do not interfere with the ability of Company or
any of its Subsidiaries to conduct their business as currently conducted or to
utilize such properties for their intended purposes. Except as permitted by this
Agreement, all such properties and assets are free and clear of Liens.

         (b) As of the Closing Date, Schedule 4.9(b) contains a true, accurate
and complete list of (i) all Real Estate Assets, and (ii) all leases, subleases
or assignments of leases (together with all amendments, modifications,
supplements, renewals or extensions of any thereof) affecting each Real Estate
Asset of any Credit Party, regardless of whether such Credit Party is the
landlord or tenant (whether directly or as an assignee or successor in interest)
under such lease, sublease or assignment. Except as specified in Schedule 4.9,
each agreement listed in clause (ii) of the immediately preceding sentence is in
full force and effect and Company does not have knowledge of any default that
has occurred and is continuing thereunder, and each such agreement constitutes
the legally valid and binding obligation of each applicable Credit Party,
enforceable against such Credit Party in accordance with its terms, except as
enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium
or similar laws relating to or limiting creditors' rights generally or by
equitable principles.

         4.10. COLLATERAL. (a) The execution and delivery of the Collateral
Documents by the Credit Parties, together with the actions taken on or prior to
the date hereof pursuant to Sections 3.1(g), are effective to create in favor of
Administrative Agent for the benefit of Lenders, as security for their


                                       55
<PAGE>   62

respective Obligations, a valid and perfected First Priority Lien on all of the
Collateral, and all filings and other actions necessary or desirable to perfect
and maintain the perfection and First Priority status of such Liens have been
duly made or taken and remain in full force and effect, other than the filing of
any UCC financing statements delivered to Administrative Agent for filing (but
not yet filed) and the periodic filing of UCC continuation statements in respect
of UCC financing statements filed by or on behalf of Administrative Agent.

         (b) Except as set forth on Schedule 4.10(b), no authorization, approval
or other action by, and no notice to or filing with, any governmental authority
or regulatory body is required for either (i) the pledge or grant by any Credit
Party of the Liens purported to be created in favor of Administrative Agent
pursuant to any of the Collateral Documents or (ii) the exercise by
Administrative Agent of any rights or remedies in respect of any Collateral
(whether specifically granted or created pursuant to any of the Collateral
Documents or created or provided for by applicable law), except for filings or
recordings contemplated by Sections 3.1(g) and 3.1(h) and except as may be
required, in connection with the disposition of any Investment Property, by laws
generally affecting the offering and sale of securities.

         (c) Except with respect to any Permitted Lien and as may have been
filed in favor of Administrative Agent as contemplated by Section 3.1(g), no
effective UCC financing statement, fixture filing or other instrument similar in
effect covering all or any part of the Collateral is on file in any filing or
recording office.

         (d) All information supplied to Administrative Agent by or on behalf of
any Credit Party with respect to any of the Collateral (in each case taken as a
whole with respect to any particular Collateral) is accurate and complete in all
material respects.

         4.11. ENVIRONMENTAL. No Credit Party nor any of its Subsidiaries nor
any of their respective Facilities or operations are subject to any outstanding
written order, consent decree or settlement agreement with any Person relating
to any Environmental Law, any Environmental Claim, or any Hazardous Materials
Activity that, individually or in the aggregate, could reasonably be expected to
have a Material Adverse Effect. No Credit Party nor any of its Subsidiaries has
received any letter or request for information under Section 104 of the
Comprehensive Environmental Response, Compensation, and Liability Act (42 U.S.C.
ss. 9604) or any comparable state law. There are and, to each Credit Party's
knowledge, have been no conditions, occurrences, or Hazardous Materials
Activities which could reasonably be expected to form the basis of an
Environmental Claim against Company or any of its Subsidiaries that,
individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect. Neither Company nor any of its Subsidiaries nor, to any
Credit Party's knowledge, any predecessor of Company or any of its Subsidiaries
has filed any notice under any Environmental Law indicating past or present
treatment of Hazardous Materials at any Facility, and none of Company's or any
of its Subsidiaries' operations involves the generation, transportation,
treatment, storage or disposal of hazardous waste, as defined under 40 C.F.R.
Parts 260-270 or any state equivalent. Compliance by Company and its
Subsidiaries with all current or reasonably foreseeable future requirements
pursuant to or under Environmental Laws could not be


                                       56
<PAGE>   63

reasonably expected to have, individually or in the aggregate, a Material
Adverse Effect. No event or condition has occurred or is occurring with respect
to Company or any of its Subsidiaries relating to any Environmental Law, any
Release of Hazardous Materials, or any Hazardous Materials Activity which
individually or in the aggregate has had, or could reasonably be expected to
have, a Material Adverse Effect.

         4.12. NO DEFAULTS; MATERIAL CONTRACTS. No Credit Party is in default in
the performance, observance or fulfillment of any of the obligations, covenants
or conditions contained in any of its Contractual Obligations, and no condition
exists that, with the giving of notice or the lapse of time or both, could
constitute such a default, except where the consequences, direct or indirect, of
such default or defaults, if any, could not reasonably be expected to have a
Material Adverse Effect. Schedule 4.12 contains a true, correct and complete
list of all the Material Contracts in effect on the Closing Date, and except as
described thereon, all such Material Contracts are in full force and effect and
no defaults currently exist thereunder by any Credit Party or, to the knowledge
of any Credit Party, by any other Person.

         4.13. GOVERNMENTAL REGULATION. Neither Company nor any of its
Subsidiaries is subject to regulation under the Investment Company Act, Public
Utility Holding Company Act of 1935 or the Federal Power Act or under any other
federal or state statute or regulation which may limit its ability to incur
Indebtedness or which may otherwise render all or any portion of the Obligations
unenforceable; provided that with respect to the Investment Company Act, Company
has applied, as of the Closing Date, for an order pursuant to Section 6(c) of
the Investment Company Act declaring that Company and its Subsidiaries are
exempt from the provisions of the Investment Company Act; provided further that,
as of the Initial Funding Date and at all times thereafter that Loans are
outstanding, each Credit Party will be exempt from the provisions of the
Investment Company Act and will at no such time be required to be registered as
an "investment company" within the meaning of the Investment Company Act.

         4.14. MARGIN STOCK. Neither Company nor any of its Subsidiaries 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. The
pledge of the Investment Property pursuant the Pledge and Security Agreement
does not violate Regulation T, U or X of the Board of Governors of the Federal
Reserve System.

         4.15. EMPLOYEE MATTERS. There is no strike or work stoppage in
existence or threatened involving Company or any of its Subsidiaries that could
reasonably be expected to have a Material Adverse Effect.

         4.16. EMPLOYEE BENEFIT PLANS. Company, each of its Subsidiaries and
each of their respective ERISA Affiliates are in compliance with all applicable
provisions and requirements of ERISA and the regulations and published
interpretations thereunder with respect to each Employee Benefit Plan, and have
performed all their obligations under each Employee Benefit Plan. Each Employee
Benefit Plan which is intended to qualify under Section 401(a) of the Internal
Revenue


                                       57
<PAGE>   64

Code is so qualified. No ERISA Event has occurred or is reasonably expected to
occur. Except to the extent required under Section 4980B of the Internal Revenue
Code, no Employee Benefit Plan provides health or welfare benefits (through the
purchase of insurance or otherwise) for any retired or former employee of
Company, any of its Subsidiaries or any of their respective ERISA Affiliates. As
of the most recent valuation date for any Pension Plan, the amount of unfunded
benefit liabilities (as defined in Section 4001(a)(18) of ERISA), individually
or in the aggregate for all Pension Plans (excluding for purposes of such
computation any Pension Plans with respect to which assets exceed benefit
liabilities), does not exceed $5,000,000. As of the most recent valuation date
for each Multiemployer Plan for which the actuarial report is available, the
potential liability of Company, its Subsidiaries and their respective ERISA
Affiliates for a complete withdrawal from such Multiemployer Plan (within the
meaning of Section 4203 of ERISA), when aggregated with such potential liability
for a complete withdrawal from all Multiemployer Plans, based on information
available pursuant to Section 4221(e) of ERISA, does not exceed $5,000,000.

         4.17. CERTAIN FEES. No broker's or finder's fee or commission will be
payable with respect hereto or any of the transactions contemplated hereby.

         4.18. SOLVENCY. Each Credit Party is and, upon the incurrence of any
Obligation by such Credit Party on any date on which this representation and
warranty is made, will be, Solvent.

         4.19. EXISTING INDENTURES. Borrower has delivered to Syndication Agent
and Administrative Agent complete and correct copies of each Existing Indenture
and of all exhibits and schedules thereto.

         4.20. YEAR 2000 ISSUES. Company and its Subsidiaries have (a) engaged
in a process of assessment of the existence of any Year 2000 Issues reasonably
appropriate to the scope and complexity of their respective Systems; (b) adopted
and are successfully implementing a plan of correction ("PLAN OF CORRECTION")
which Company reasonably believes will result in a substantial elimination of
any Year 2000 Issues before any processing failure of a System or of Systems due
to Year 2000 Issues which might have a material effect on the business,
operations or financial performance of Company and, in the case of all Systems
critical to the business or operations of Company and its Subsidiaries, a
virtually complete elimination of Year 2000 Issues by September 30, 1999; (c)
adopted and are successfully implementing validation procedures reasonably
calculated to test on an ongoing basis the sufficiency of the Plan of
Correction, its implementation, and the correction of Year 2000 Issues in any
System; (d) adopted and are successfully implementing policies and procedures
requiring regular reports to, and monitoring by, senior management of Company
concerning the foregoing matters; and (e) provided Administrative Agent true and
correct copies of the written Plan of Correction, and related implementation
budgets, reviewed and approved by Company's Board of Directors; it being
understood with respect to the foregoing that no representation or warranty is
being made with respect to the Systems of Persons to whose networks Company and
its Subsidiaries are interconnected.

<PAGE>   65

         4.21. DISCLOSURE. No representation or warranty of any Credit Party
contained in any Credit Document or in any other document, certificate or
written statement furnished to Lenders by or on behalf of Company or any of its
Subsidiaries (other than projections and pro forma financial information
contained in such materials) for use in connection with the transactions
contemplated hereby contains any untrue statement of a material fact or omits to
state a material fact (known to Borrower or Company, in the case of any document
not furnished by either of them) necessary in order to make the statements
contained herein or therein not misleading in light of the circumstances in
which the same were made. Any projections and pro forma financial information
contained in such materials are based upon good faith estimates and assumptions
believed by Company to be reasonable at the time made, it being recognized by
Lenders that such projections as to future events are not to be viewed as facts
and that actual results during the period or periods covered by any such
projections may differ from the projected results. There are no facts known (or
which should upon the reasonable exercise of diligence be known) to Company or
Borrower (excluding matters of a general economic nature or matters regarding
the telecommunications industry which are generally available to the public)
that, individually or in the aggregate, could reasonably be expected to result
in a Material Adverse Effect and that have not been disclosed herein or in such
other documents, certificates and statements furnished to Lenders for use in
connection with the transactions contemplated hereby.

         4.22. NO BURDENSOME RESTRICTIONS. Neither Company nor any of its
Subsidiaries is a party to or bound by any Contractual Obligation which could
reasonably be expected to have a Material Adverse Effect.

SECTION 5.  AFFIRMATIVE COVENANTS

         Each Credit Party covenants and agrees that so long as any Commitment
is in effect and until payment in full of all Obligations (other than inchoate
indemnification obligations with respect to claims, losses or liabilities which
have not yet arisen and are not yet due and payable), each Credit Party shall
perform, and shall cause each of its Subsidiaries to perform, all covenants in
this Section 5.

         5.1. FINANCIAL STATEMENTS AND OTHER REPORTS. Borrower will deliver to
Administrative Agent and Lenders:

from the consolidated financial statements that would have been delivered
pursuant to such subdivisions had no such change in accounting principles and
policies been made, then together with the first delivery of such financial
statements after such change one or more a

respect to Company or any of its Subsidiaries as from time to time may be
reasonably requested by any Lender.

         5.2. EXISTENCE. Except as otherwise permitted under Section 6.8, each
Credit Party will, and will cause each of its Subsidiaries to, at all times
preserve and keep in full force and effect its existence and all rights and
franchises material to its business; provided, no Credit Party nor any of its
Subsidiaries shall be required to preserve any such existence, right or
franchise if such Person's Board of Directors (or similar governing body) shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of such Person, and that the loss thereof is not disadvantageous in
any material respect to such Person or Lenders.

         5.3. PAYMENT OF TAXES AND CLAIMS. Each Credit Party will, and will
cause each of its Subsidiaries to, pay all taxes, assessments and other
governmental charges imposed upon it or any of its properties or assets or in
respect of any of its income, businesses or franchises before any penalty
accrues thereon, and all claims (including claims for labor, services, materials
and supplies) for sums that have become due and payable and that by law have or
may become a Lien upon any of its properties or assets, prior to the time when
any penalty or fine shall be incurred with respect thereto, except where the
failure to do so could not reasonably be expected to result in a Material
Adverse Effect, and provided, no such charge or claim need be paid if it is
being contested in good faith by appropriate proceedings promptly instituted and
diligently conducted, so long as (a) such reserve or other appropriate
provision, if any, as shall be required in conformity with GAAP shall have been
made therefor, and (b) in the case of a charge or claim which has or may become
a Lien against any of the Collateral, such contest proceedings conclusively
operate to stay the sale of any portion of the Collateral to satisfy such charge
or claim. Company will not, nor will it permit any of its Subsidiaries to, file
or consent to the filing of any consolidated income tax return with any Person
(other than Company or any of its Subsidiaries).

         5.4. MAINTENANCE OF PROPERTIES. Each Credit Party will, and will cause
each of its Subsidiaries to, maintain or cause to be maintained in good repair,
working order and condition, ordinary wear and tear excepted, all material
properties used or useful in the business of Company and its Subsidiaries and
from time to time will make or cause to be made all appropriate repairs,
renewals and replacements thereof.

         5.5. INSURANCE. Company will maintain or cause to be maintained, with
financially sound and reputable insurers, such public liability insurance, third
party property damage insurance, business interruption insurance and casualty
insurance with respect to liabilities, losses or damage in respect of the
assets, properties and businesses of Company and its Subsidiaries as may
customarily be carried or maintained under similar circumstances by Persons of
established reputation engaged in similar businesses, in each case in such
amounts (giving effect to self-insurance), with such deductibles, covering such
risks and otherwise on such terms and conditions as shall be customary for such
Persons. Without limiting the generality of the foregoing, Company will maintain
or cause to be maintained (a) flood insurance with respect to each Flood Hazard
Property that is located in a community that participates in the National Flood
Insurance Program,


                                       63
<PAGE>   70

in each case in compliance with any applicable regulations of the Board of
Governors of the Federal Reserve System, and (b) replacement value casualty
insurance on the Collateral under such policies of insurance, with such
insurance companies, in such amounts, with such deductibles, and covering such
risks as are at all times carried or maintained under similar circumstances by
Persons of established reputation engaged in similar businesses. Each such
policy of insurance shall (i) name Administrative Agent for the benefit of
Lenders as an additional insured thereunder as its interests may appear and (ii)
in the case of each business interruption and casualty insurance policy, contain
a loss payable clause or endorsement, satisfactory in form and substance to
Administrative Agent, that names Administrative Agent for the benefit of Lenders
as the loss payee thereunder for any covered loss in excess of $1,000,000 and
provides for at least thirty (30) days prior written notice to Administrative
Agent of any modification adverse in any respect to Administrative Agent or
Lenders or cancellation of such policy.

         5.6. BOOKS AND RECORDS; INSPECTIONS; LENDERS MEETINGS. Each Credit
Party will, and will cause each of its Subsidiaries to, keep proper books of
record and account in which full, true and correct entries are made of all
dealings and transactions in relation to its business and activities. Each
Credit Party will, and will cause each of its Subsidiaries to, permit any
authorized representatives designated by any Lender to visit and inspect any of
the Facilities of Company or of any of its Subsidiaries, to inspect, copy and
take extracts from its and their financial and accounting records, and to
discuss its and their affairs, finances and accounts with its and their officers
and independent public accountants, all upon reasonable notice and at such
reasonable times during normal business hours and as often as may reasonably be
requested. Borrower and Company will, upon the request of Administrative Agent
or Requisite Lenders, participate in a meeting of Administrative Agent and
Lenders once during each Fiscal Year to be held at Company's corporate offices
(or at such other location as may be agreed to by Borrower and Administrative
Agent) at such time as may be agreed to by Borrower and Administrative Agent.

         5.7.  COMPLIANCE WITH LAWS; CONTRACTUAL OBLIGATIONS.

         (a) Each Credit Party will comply, and shall cause each of its
Subsidiaries and all other Persons, if any, on or occupying any Facilities to
comply, with the requirements of all Contractual Obligations and applicable
laws, rules, regulations and orders of any governmental authority (including all
Environmental Laws), noncompliance with which could reasonably be expected to
have, individually or in the aggregate, a Material Adverse Effect.

         (b) Company will use reasonable best efforts to obtain an order
pursuant to Section 6(c) of the Investment Company Act declaring that Company
and its Subsidiaries are exempt from the provisions of the Investment Company
Act, and as of the Initial Funding Date and at all times thereafter that Loans
are outstanding, will use such efforts to seek to maintain such exemption.

any of its Subsidiaries to, directly or indirectly, become or remain liable as
lessee or as a guarantor or other surety with respect to any lease of any
property (whether real, personal or mixed), whether now owned or hereafter
acquired, which Company or any of its Subsidiaries (a) has sold or transferred


                                       80
<PAGE>   87

or is to sell or to transfer to any other Person (other than Company or any of
its Subsidiaries), or (b) intends to use for substantially the same purpose as
any other property which has been or is to be sold or transferred by Company or
any of its Subsidiaries to any Person (other than Company or any of its
Subsidiaries) in connection with such lease.

         6.11. SALE OR DISCOUNT OF RECEIVABLES. No Credit Party shall, nor shall
it permit any of its Subsidiaries to, directly or indirectly, sell with
recourse, or discount or otherwise sell for less than the face value thereof,
any of its notes or accounts receivable (it being understood that the
restrictions contained in this Section 6.11 shall not apply to any write-off of
bad debt in the ordinary course of business consistent with prior practice).

         6.12. TRANSACTIONS WITH SHAREHOLDERS AND AFFILIATES. No Credit Party
shall, nor shall it permit any of its Subsidiaries to, directly or indirectly,
enter into or permit to exist any transaction (including the purchase, sale,
lease or exchange of any property or the rendering of any service) with any
holder of 5% or more of any class of equity Securities of Company or any of its
Subsidiaries or with any Affiliate of Company or of any such holder, on terms
that are less favorable to Company or that Subsidiary, as the case may be, than
those that might be obtained at the time from Persons who are not such a holder
or Affiliate; provided, the foregoing restriction shall not apply to (a) any
transaction between Company and any of its Subsidiaries or between any of the
Subsidiaries; (b) reasonable and customary fees and expenses paid to members of

holding company.

         6.14. AMENDMENTS OR WAIVERS OF EXISTING INDENTURES/SUBORDINATED
INDEBTEDNESS. No Credit Party shall, nor shall it permit any of its Subsidiaries
to, amend or otherwise change the terms of the Existing Indentures or any
Subordinated Indebtedness, or make any payment consistent with an amendment
thereof or change thereto, if the effect of such amendment or change is to
increase the interest rate on the Existing Indentures or such Subordinated
Indebtedness, change (to earlier dates) any dates upon which payments of
principal or interest are due thereon, change any event of default or condition
to an event of default with respect thereto (other than to eliminate any such
event of default or increase any grace period related thereto), change the
redemption, prepayment or defeasance provisions thereof, change the
subordination provisions of such Subordinated Indebtedness (or of any guaranty
thereof), or change any collateral therefor (other than to release such
collateral), or if the effect of such amendment or change, together with all
other amendments or changes made, is to increase materially the obligations of
the obligor thereunder or to confer any additional rights on the holders of
notes issued under the Existing Indentures or such Subordinated


                                       81
<PAGE>   88

Indebtedness (or a trustee or other representative on their behalf) which would
be adverse to any Credit Party or Lenders.

SECTION 7.  GUARANTY

         7.1. GUARANTY OF THE OBLIGATIONS. Subject to the provisions of Section
7.2, Guarantors jointly and severally hereby irrevocably and unconditionally
guaranty the due and punctual payment in full of all Obligations when the same
shall become due, whether at stated maturity, by required prepayment,
declaration, acceleration, demand or otherwise (including amounts that would
become due but for the operation of the automatic stay under Section 362(a) of
the Bankruptcy Code, 11 U.S.C. ss. 362(a)).

         7.2. CONTRIBUTION BY GUARANTORS. Each Guarantor desires to allocate
among themselves (collectively, the "CONTRIBUTING GUARANTORS"), in a fair and
equitable manner, their obligations arising under this Guaranty. Accordingly, in
the event any payment or distribution is made on any date by a Guarantor under
this Guaranty (a "FUNDING GUARANTOR") that exceeds its Fair Share as of such
date, that Funding Guarantor shall be entitled to a contribution from each of
the other Contributing Guarantors in the amount of such other Contributing
Guarantor's Fair Share Shortfall as of such date, with the result that all such
contributions will cause each Contributing Guarantor's Aggregate Payments to
equal its Fair Share as of such date. "FAIR SHARE" means, with respect to a
Contributing Guarantor as of any date of determination, an amount equal to (a)
the ratio of (i) the Fair Share Contribution Amount with respect to such
Contributing Guarantor to (ii) the aggregate of the Fair Share Contribution
Amounts with respect to all Contributing Guarantors multiplied by (b) the
aggregate amount paid or distributed on or before such date by all Funding
Guarantors under this Guaranty in respect of the obligations guarantied. "FAIR
SHARE SHORTFALL" means, with respect to a Contributing Guarantor as of any date
of determination, the excess, if any, of the Fair Share of such Contributing
Guarantor over the Aggregate Payments of such Contributing Guarantor. "FAIR
SHARE CONTRIBUTION AMOUNT" means, with respect to a Contributing Guarantor as of
any date of determination, the maximum aggregate amount of the obligations of
such Contributing Guarantor under this Guaranty that would not render its
obligations hereunder or thereunder subject to avoidance as a fraudulent
transfer or conveyance under Section 548 of Title 11 of the United States Code
or any applicable provisions of comparable state law; provided, solely for
purposes of calculating the "FAIR SHARE CONTRIBUTION AMOUNT" with respect to any
Contributing Guarantor for purposes of this Section 7.2, any assets or
liabilities of such Contributing Guarantor arising by virtue of any rights to
subrogation, reimbursement or indemnification or any rights to or obligations of
contribution hereunder shall not be considered as assets or liabilities of such
Contributing Guarantor. "AGGREGATE PAYMENTS" means, with respect to a
Contributing Guarantor as of any date of determination, an amount equal to (1)
the aggregate amount of all payments and distributions made on or before such
date by such Contributing Guarantor in respect of this Guaranty (including,
without limitation, in respect of this Section 7.2), minus (2) the aggregate
amount of all payments


                                       82
<PAGE>   89

received on or before such date by such Contributing Guarantor from the other
Contributing Guarantors as contributions under this Section 7.2. The amounts
payable as contributions hereunder shall be determined as of the date on which
the related payment or distribution is made by the applicable Funding Guarantor.
The allocation among Contributing Guarantors of their obligations as set forth
in this Section 7.2 shall not be construed in any way to limit the liability of
any Contributing Guarantor hereunder. Each Guarantor is a beneficiary to the
contribution agreement set forth in this Section 7.2.

         7.3. PAYMENT BY GUARANTORS. Subject to Section 7.2, Guarantors hereby
jointly and severally agree, in furtherance of the foregoing and not in
limitation of any other right which any Beneficiary may have at law or in equity
against any Guarantor by virtue hereof, that upon the failure of Borrower to pay
any of the Obligations when and as the same shall become due, whether at stated
maturity, by required prepayment, declaration, acceleration, demand or otherwise
(including amounts that would become due but for the operation of the automatic
stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C. ss. 362(a)),
Guarantors will upon demand pay, or cause to be paid, in cash, to Administrative
Agent for the ratable benefit of Beneficiaries, an amount equal to the sum of
the unpaid principal amount of all Obligations then due as aforesaid, accrued
and unpaid interest on such Obligations (including interest which, but for the
filing of a petition in bankruptcy with respect to Borrower, would have accrued
on such Obligations, whether or not a claim is allowed against Borrower for such
interest in the related bankruptcy proceeding) and all other Obligations then
owed to Beneficiaries as aforesaid.

         7.4. LIABILITY OF GUARANTORS ABSOLUTE. Each Guarantor agrees that its
obligations hereunder are irrevocable, absolute, independent and unconditional
and shall not be affected by any circumstance which constitutes a legal or
equitable discharge of a guarantor or surety other than payment in full of the
Obligations. In furtherance of the foregoing and without limiting the generality
thereof, each Guarantor agrees as follows:

         (a) this Guaranty is a guaranty of payment when due and not of
collectibility;

         (b) Administrative Agent may enforce this Guaranty upon the occurrence
of an Event of Default notwithstanding the existence of any dispute between
Borrower and any Beneficiary with respect to the existence of such Event of
Default;

         (c) the obligations of each Guarantor hereunder are independent of the
obligations of Borrower and the obligations of any other guarantor (including
any other Guarantor) of the obligations of Borrower, and a separate action or
actions may be brought and prosecuted against such Guarantor whether or not any
action is brought against Borrower or any of such other guarantors and whether
or not Borrower is joined in any such action or actions;

         (d) payment by any Guarantor of a portion, but not all, of the
Obligations shall in no way limit, affect, modify or abridge any Guarantor's
liability for any portion of the Obligations which has not been paid. Without
limiting the generality of the foregoing, if Administrative Agent is awarded


                                       83
<PAGE>   90

a judgment in any suit brought to enforce any Guarantor's covenant to pay a
portion of the Obligations, such judgment shall not be deemed to release such
Guarantor from its covenant to pay the portion of the Obligations that is not
the subject of such suit, and such judgment shall not, except to the extent
satisfied by such Guarantor, limit, affect, modify or abridge any other
Guarantor's liability hereunder in respect of the Obligations;

         (e) any Beneficiary, upon such terms as it deems appropriate, without
notice or demand and without affecting the validity or enforceability hereof or
giving rise to any reduction, limitation, impairment, discharge or termination
of any Guarantor's liability hereunder, from time to time may (i) renew, extend,
accelerate, increase the rate of interest on, or otherwise change the time,
place, manner or terms of payment of the Obligations; (ii) settle, compromise,
release or discharge, or accept or refuse any offer of performance with respect
to, or substitutions for, the Obligations or any agreement relating thereto
and/or subordinate the payment of the same to the payment of any other
obligations; (iii) request and accept other guaranties of the Obligations and
take and hold security for the payment hereof or the Obligations; (iv) release,
surrender, exchange, substitute, compromise, settle, rescind, waive, alter,
subordinate or modify, with or without consideration, any security for payment
of the Obligations, any other guaranties of the Obligations, or any other
obligation of any Person (including any other Guarantor) with respect to the
Obligations; (v) enforce and apply any security now or hereafter held by or for
the benefit of such Beneficiary in respect hereof or the Obligations and direct
the order or manner of sale thereof, or exercise any other right or remedy that
such Beneficiary may have against any such security, in each case as such
Beneficiary in its discretion may determine consistent herewith and any
applicable security agreement or Hedge Agreement, including foreclosure on any
such security pursuant to one or more judicial or nonjudicial sales, whether or
not every aspect of any such sale is commercially reasonable, and even though
such action operates to impair or extinguish any right of reimbursement or
subrogation or other right or remedy of any Guarantor against Borrower or any
security for the Obligations; and (vi) exercise any other rights available to it
under the Credit Documents or the Hedge Agreements; and

         (f) this Guaranty and the obligations of Guarantors hereunder shall be
valid and enforceable and shall not be subject to any reduction, limitation,
impairment, discharge or termination for any reason (other than payment in full
of the Obligations), including the occurrence of any of the following, whether
or not any Guarantor shall have had notice or knowledge of any of them: (i) any
failure or omission to assert or enforce or agreement or election not to assert
or enforce, or the stay or enjoining, by order of court, by operation of law or
otherwise, of the exercise or enforcement of, any claim or demand or any right,
power or remedy (whether arising under the Credit Documents or the Hedge
Agreements, at law, in equity or otherwise) with respect to the Obligations or
any agreement relating thereto, or with respect to any other guaranty of or
security for the payment of the Obligations; (ii) any rescission, waiver,
amendment or modification of, or any consent to departure from, any of the terms
or provisions (including provisions relating to events of default) hereof, any
of the other Credit Documents or the Hedge Agreements or any agreement or
instrument executed pursuant hereto or thereto, or of any other guaranty or
security for the Obligations, in each case whether or not in accordance with the
terms hereof or such Credit


                                       84
<PAGE>   91

Document or Hedge Agreement or any agreement relating to such other guaranty or
security; (iii) the Obligations, or any agreement relating thereto, at any time
being found to be illegal, invalid or unenforceable in any respect; (iv) the
application of payments received from any source (other than payments received
pursuant to the other Credit Documents or any Hedge Agreement or from the
proceeds of any security for the Obligations, except to the extent such security
also serves as collateral for indebtedness other than the Obligations) to the
payment of indebtedness other than the Obligations, even though any Beneficiary
might have elected to apply such payment to any part or all of the Obligations;
(v) any Beneficiary's consent to the change, reorganization or termination of
the corporate structure or existence of Company or any of its Subsidiaries and
to any corresponding restructuring of the Obligations; (vi) any failure to
perfect or continue perfection of a security interest in any collateral which
secures any of the Obligations; (vii) any defenses, set-offs or counterclaims
which Borrower may allege or assert against any Beneficiary in respect of the
Obligations, including failure of consideration, breach of warranty, payment,
statute of frauds, statute of limitations, accord and satisfaction and usury;
and (viii) any other act or thing or omission, or delay to do any other act or
thing, which may or might in any manner or to any extent vary the risk of any
Guarantor as an obligor in respect of the Obligations.

         7.5. WAIVERS BY GUARANTORS. Each Guarantor hereby waives, for the
benefit of Beneficiaries: (a) any right to require any Beneficiary, as a
condition of payment or performance by such Guarantor, to (i) proceed against
Borrower, any other guarantor (including any other Guarantor) of the Obligations
or any other Person, (ii) proceed against or exhaust any security held from
Borrower, any such other guarantor or any other Person, (iii) proceed against or
have resort to any balance of any deposit account or credit on the books of any
Beneficiary in favor of Borrower or any other Person, or (1) pursue any other
remedy in the power of any Beneficiary whatsoever; (b) any defense arising by
reason of the incapacity, lack of authority or any disability or other defense
of Borrower including any defense based on or arising out of the lack of
validity or the unenforceability of the Obligations or any agreement or
instrument relating thereto or by reason of the cessation of the liability of
Borrower from any cause other than payment in full of the Obligations; (c) any
defense based upon any statute or rule of law which provides that the obligation
of a surety must be neither larger in amount nor in other respects more
burdensome than that of the principal; (d) any defense based upon any
Beneficiary's errors or omissions in the administration of the Obligations,
except behavior which amounts to gross negligence, willful misconduct or bad
faith; (e) (i) any principles or provisions of law, statutory or otherwise,
which are or might be in conflict with the terms hereof and any legal or
equitable discharge of such Guarantor's obligations hereunder, (ii) the benefit
of any statute of limitations affecting such Guarantor's liability hereunder or
the enforcement hereof, (iii) any rights to set-offs, recoupments and
counterclaims, and (iv) promptness, diligence and any requirement that any
Beneficiary protect, secure, perfect or insure any security interest or lien or
any property subject thereto; (f) notices, demands, presentments, protests,
notices of protest, notices of dishonor and notices of any action or inaction,
including acceptance hereof, notices of default hereunder, the Hedge Agreements
or any agreement or instrument related hereto or thereto, notices of any
renewal, extension or modification of the Obligations or any agreement related
thereto, notices of any extension of credit to Borrower and notices of any of
the matters referred to in Section 7.4 and any right to consent to any thereof;
and (g) any defenses or benefits that may be


                                       85
<PAGE>   92

derived from or afforded by law which limit the liability of or exonerate
guarantors or sureties, or which may conflict with the terms hereof.

         7.6. GUARANTORS' RIGHTS OF SUBROGATION, CONTRIBUTION, ETC. Each
Guarantor hereby waives any claim, right or remedy, direct or indirect, that
such Guarantor now has or may hereafter have against Borrower or any of its
assets in connection with this Guaranty or the performance by such Guarantor of
its obligations hereunder for so long (but only for so long) as any Obligation
of any Credit Party remains outstanding, in each case whether such claim, right
or remedy arises in equity, under contract, by statute, under common law or
otherwise and including without limitation (a) any right of subrogation,
reimbursement or indemnification that such Guarantor now has or may hereafter
have against Borrower with respect to the Obligations, (b) any right to enforce,
or to participate in, any claim, right or remedy that any Beneficiary now has or
may hereafter have against Borrower, and (c) any benefit of, and any right to
participate in, any collateral or security now or hereafter held by any
Beneficiary. In addition, until the Obligations shall have been indefeasibly
paid in full and the Commitments shall have terminated each Guarantor shall
withhold exercise of any right of contribution such Guarantor may have against
any other guarantor (including any other Guarantor) of the Obligations,
including, without limitation, any such right of contribution as contemplated by
Section 7.2. Each Guarantor further agrees that, to the extent the waiver or
agreement to withhold the exercise of its rights of subrogation, reimbursement,
indemnification and contribution as set forth herein is found by a court of
competent jurisdiction to be void or voidable for any reason, any rights of
subrogation, reimbursement or indemnification such Guarantor may have against
Borrower or against any collateral or security, and any rights of contribution
such Guarantor may have against any such other guarantor, shall be junior and
subordinate to any rights any Beneficiary may have against Borrower, to all
right, title and interest any Beneficiary may have in any such collateral or
security, and to any right any Beneficiary may have against such other
guarantor. If any amount shall be paid to any Guarantor on account of any such
subrogation, reimbursement, indemnification or contribution rights at any time
when all Obligations shall not have been paid in full, such amount shall be held
in trust for guarantied party on behalf of Beneficiaries and shall forthwith be
paid over to guarantied party for the benefit of Beneficiaries to be credited
and applied against the Obligations, whether matured or unmatured, in accordance
with the terms hereof.

         7.7. SUBORDINATION OF OTHER OBLIGATIONS. Any Indebtedness of Borrower
or any Guarantor now or hereafter held by any Guarantor (the "OBLIGEE
GUARANTOR") is hereby subordinated in right of payment to the Obligations, and
any such indebtedness collected or received by the Obligee Guarantor after an
Event of Default has occurred and is continuing shall be held in trust for
Administrative Agent on behalf of Beneficiaries and shall forthwith be paid over
to Administrative Agent for the benefit of Beneficiaries to be credited and
applied against the Obligations but without affecting, impairing or limiting in
any manner the liability of the Obligee Guarantor under any other provision
hereof.

         7.8. CONTINUING GUARANTY. This Guaranty is a continuing guaranty and
shall remain in effect until all of the Obligations shall have been paid in full
and the Commitments shall have


                                       86
<PAGE>   93

terminated. Each Guarantor hereby irrevocably waives any right to revoke this
Guaranty as to future transactions giving rise to any Obligations.

         7.9. AUTHORITY OF GUARANTORS OR BORROWER. It is not necessary for any
Beneficiary to inquire into the capacity or powers of any Guarantor or Borrower
or the officers, directors or any agents acting or purporting to act on behalf
of any of them.

         7.10. FINANCIAL CONDITION OF BORROWER. Any Loan may be granted to
Borrower or continued from time to time, and any Hedge Agreement may be entered
into from time to time, in each case without notice to or authorization from any
Guarantor regardless of the financial or other condition of Borrower at the time
of any such grant or continuation or at the time such Hedge Agreement is entered
into, as the case may be. No Beneficiary shall have any obligation to disclose
or discuss with any Guarantor its assessment, or any Guarantor's assessment, of
the financial condition of Borrower. Each Guarantor has adequate means to obtain
information from Borrower on a continuing basis concerning the financial
condition of Borrower and its ability to perform its obligations under the
Credit Documents and the Hedge Agreements, and each Guarantor assumes the
responsibility for being and keeping informed of the financial condition of
Borrower and of all circumstances bearing upon the risk of nonpayment of the
Obligations. Each Guarantor hereby waives and relinquishes any duty on the part
of any Beneficiary to disclose any matter, fact or thing relating to the
business, operations or conditions of Borrower now known or hereafter known by
any Beneficiary.

         7.11. BANKRUPTCY, ETC. (a) So long as any Obligations remain
outstanding, no Guarantor shall, without the prior written consent of
Administrative Agent acting pursuant to the instructions of Requisite Lenders,
commence or join with any other Person in commencing any bankruptcy,
reorganization or insolvency proceedings of or against Borrower. The obligations
of Guarantors hereunder shall not be reduced, limited, impaired, discharged,
deferred, suspended or terminated by any proceeding, voluntary or involuntary,
involving the bankruptcy, insolvency, receivership, reorganization, liquidation
or arrangement of Borrower or by any defense which Borrower may have by reason
of the order, decree or decision of any court or administrative body resulting
from any such proceeding.

         (b) Each Guarantor acknowledges and agrees that any interest on any
portion of the Obligations which accrues after the commencement of any
proceeding referred to in clause (a) above (or, if interest on any portion of
the Obligations ceases to accrue by operation of law by reason of the
commencement of said proceeding, such interest as would have accrued on such
portion of the Obligations if said proceedings had not been commenced) shall be
included in the Obligations because it is the intention of Guarantors and
Beneficiaries that the Obligations which are guarantied by Guarantors pursuant
hereto should be determined without regard to any rule of law or order which may
relieve Borrower of any portion of such Obligations. Guarantors will permit any
trustee in bankruptcy, receiver, debtor in possession, assignee for the benefit
of creditors or similar person to pay Administrative Agent, or allow the claim
of Administrative Agent in respect of, any such interest accruing after the date
on which such proceeding is commenced.


                                       87
<PAGE>   94

         (c) In the event that all or any portion of the Obligations are paid by
Borrower, the obligations of Guarantors hereunder shall continue and remain in
full force and effect or be reinstated, as the case may be, in the event that
all or any part of such payment(s) are rescinded or recovered directly or
indirectly from any Beneficiary as a preference, fraudulent transfer or
otherwise, and any such payments which are so rescinded or recovered shall
constitute Obligations for all purposes hereunder.

         7.12. NOTICE OF EVENTS. As soon as any Guarantor obtains knowledge
thereof, such Guarantor shall give Administrative Agent written notice of any
condition or event which has resulted in (i) a material adverse change in the
financial condition of any Guarantor or Borrower or (ii) a breach of or
noncompliance with any term, condition or covenant contained herein, any other
Credit Document, any Hedge Agreement or any other document delivered pursuant
hereto or thereto.

         7.13. DISCHARGE OF GUARANTY UPON SALE OF GUARANTOR. If all of the
equity Securities of any Guarantor or any of its successors in interest
hereunder shall be sold or otherwise disposed of (including by merger or
consolidation) in accordance with the terms and conditions hereof, the Guaranty
of such Guarantor or such successor in interest, as the case may be, hereunder
shall automatically be discharged and released without any further action by any
Beneficiary or any other Person effective as of the time of such Asset Sale;
provided, as a condition precedent to such discharge and release, Administrative
Agent shall have received evidence satisfactory to it that arrangements
satisfactory to it have been made for delivery to Administrative Agent of the
applicable Net Asset Sale Proceeds of such disposition pursuant to Section
2.13(a).

SECTION 8.  EVENTS OF DEFAULT

         8.1. Events of Default. If any one or more of the following conditions
or events shall occur:

         (a) failure by Borrower to pay (i) when due any installment of
principal of any Loan when due, whether at stated maturity, by acceleration, by
notice of voluntary prepayment, by mandatory prepayment or otherwise; or (ii)
any interest on any Loan or any fee or any other amount due hereunder within
five (5) days after the date due; or

         (b) (i) failure of any Credit Party to pay when due any principal of or
interest on or any other amount payable in respect of one or more items of
Indebtedness (other than Indebtedness referred to in Section 8.1(a)) in an
individual principal amount of $1,000,000 or more or with an aggregate principal
amount of $5,000,000 or more, in each case beyond the end of any grace period
provided therefor; or (ii) breach or default by any Credit Party with respect to
any other material term of (1) one or more items of Indebtedness in the
individual or aggregate principal amounts referred to in clause (i) above or (2)
any loan agreement, mortgage, indenture or other agreement relating to such
item(s) of Indebtedness, if the effect of such breach or default is to cause, or
to permit the holder or holders of that Indebtedness (or a trustee on behalf of
such holder or holders) to cause, that Indebtedness to become or be declared due
and payable prior to its stated maturity or the stated


                                       88
<PAGE>   95

maturity of any underlying obligation, as the case may be (upon the giving or
receiving of notice, lapse of time, both, or otherwise); or

         (c) failure of any Credit Party to perform or comply with any term or
condition contained in Section 2.3, 5.1(g), 5.2 or Section 6 (other than Section
6.6) hereof; or

or deemed made by any Credit Party in any Credit Document or in any statement or
certificate at any time given by Company or any of its Subsidiaries in writing
pursuant hereto or thereto or in connection herewith or therewith shall be false
in any material respect as the date made or deemed made; or

         (e) any Credit Party shall default in the performance of or compliance
with any term contained herein or any of the other Credit Documents, other than
any such term referred to in any other Section of this Section 8.1 and other
than Section 6.6, and such default shall not have been remedied or waived within
thirty (30) days after the earlier of (i) an officer of such Credit Party
becoming aware of such default or (ii) receipt by Borrower of notice from
Administrative Agent or any Lender of such default; or

         (f) (i) a court having jurisdiction in the premises shall enter a
decree or order for relief in respect of any Credit Party in an involuntary case
under the Bankruptcy Code or under any other applicable bankruptcy, insolvency
or similar law now or hereafter in effect, which decree or order is not stayed;
or any other similar relief shall be granted under any applicable federal or
state law; or (ii) an involuntary case shall be commenced against any Credit
Party under the Bankruptcy Code or under any other applicable bankruptcy,
insolvency or similar law now or hereafter in effect; or a decree or order of a
court having jurisdiction in the premises for the appointment of a receiver,
liquidator, sequestrator, trustee, custodian or other officer having similar
powers over any Credit Party, or over all or a substantial part of its property,
shall have been entered; or there shall have occurred the involuntary
appointment of an interim receiver, trustee or other custodian of any Credit
Party for all or a substantial part of its property; or a warrant of attachment,
execution or similar process shall have been issued against any substantial part
of the property of any Credit Party, and any such event described in this clause
(ii) shall continue for sixty (60) days unless dismissed, bonded or discharged;
or

         (g) (i) any Credit Party shall have an order for relief entered with
respect to it or commence a voluntary case under the Bankruptcy Code or under

amount of and accrued interest on the Loans, and (II) all other Obligations.

SECTION 9.  AGENTS

         9.1. APPOINTMENT OF AGENTS. GSCP and TDSI are hereby appointed Co-Lead
Arrangers, and GSCP is hereby appointed Syndication Agent hereunder, and each
Lender hereby authorizes Co-Lead Arrangers and Syndication Agent to act as its
agent in accordance with the terms hereof and the other Credit Documents. TD is
hereby appointed Administrative Agent hereunder and under the other Credit
Documents and each Lender hereby authorizes Administrative Agent to act as its
agent in accordance with the terms hereof and the other Credit Documents (except
with respect to the rights granted to it in the second sentence of Section 9.7).
MSSF is hereby appointed Documentation Agent hereunder, and each Lender hereby
authorizes Documentation Agent to act as its agent in accordance with the terms
hereof and the other Credit Documents. Each Agent hereby agrees to act upon the
express conditions contained herein and the other Credit Documents, as
applicable. The provisions of this Section 9 are solely for the benefit of
Agents and Lenders and no Credit Party shall have any rights as a third party
beneficiary of any of the provisions thereof. In performing its functions and
duties hereunder, each Agent shall act solely as an agent of Lenders and does
not assume and shall not be deemed to have assumed any obligation towards or
relationship of agency or trust with or for Company or any of its Subsidiaries.
Each of Syndication Agent and Documentation Agent, without consent of or notice
to any party hereto, may assign any and all of its rights or obligations
hereunder to any of its Affiliates. As of the Closing Date, all the respective
obligations of (i) GSCP, in its capacity as Co-Lead Arranger and Syndication
Agent, (ii) TDSI, as Co-Lead Arranger and (iii) MSSF, in its capacity as
Documentation Agent, shall terminate.

         9.2. POWERS AND DUTIES. Each Lender irrevocably authorizes each Agent
to take such action on such Lender's behalf and to exercise such powers, rights
and remedies hereunder and under the other Credit Documents as are specifically
delegated or granted to such Agent by the terms hereof and thereof, together
with such powers, rights and remedies as are reasonably incidental thereto. Each
Agent shall have only those duties and responsibilities that are expressly
specified herein and the other Credit Documents. Each Agent may exercise such
powers, rights and remedies and perform such duties by or through its agents or
employees. No Agent shall have, by reason hereof or any of the other Credit
Documents, a fiduciary relationship in respect of any Lender; and nothing herein
or any of the other Credit Documents, expressed or implied, is intended to or
shall be so construed as to impose upon any Agent any obligations in respect
hereof or any of the other Credit Documents except as expressly set forth herein
or therein.

         9.3. GENERAL IMMUNITY. (a) No Agent shall be responsible to any Lender
for the execution, effectiveness, genuineness, validity, enforceability,
collectibility or sufficiency hereof or any other Credit Document or for any
representations, warranties, recitals or statements made herein or therein


                                       91
<PAGE>   98

or made in any written or oral statements or in any financial or other
statements, instruments, reports or certificates or any other documents
furnished or made by any of Agent to Lenders or by or on behalf of Borrower to
any Agent or any Lender in connection with the Credit Documents and the
transactions contemplated thereby or for the financial condition or business
affairs of any Credit Party or any other Person liable for the payment of any
Obligations, nor shall any Agent be required to ascertain or inquire as to the
performance or observance of any of the terms, conditions, provisions, covenants
or agreements contained in any of the Credit Documents or as to the use of the
proceeds of the Loans or as to the existence or possible existence of any Event
of Default or Default. Anything contained herein to the contrary
notwithstanding, Administrative Agent shall not have any liability arising from
confirmations of the amount of outstanding Loans.

         (b) No Agent nor any of its officers, partners, directors, employees or
agents shall be liable to Lenders for any action taken or omitted by any Agent
under or in connection with any of the Credit Documents except to the extent
caused by such Agent's gross negligence or willful misconduct. Each Agent shall
be entitled to refrain from any act or the taking of any action (including the
failure to take an action) in connection herewith or any of the other Credit
Documents or from the exercise of any power, discretion or authority vested in
it hereunder or thereunder unless and until such Agent shall have received
instructions in respect thereof from Requisite Lenders (or such other Lenders as
may be required to give such instructions under Section 10.5) and, upon receipt
of such instructions from Requisite Lenders (or such other Lenders, as the case
may be), such Agent shall be entitled to act or (where so instructed) refrain
from acting, or to exercise such power, discretion or authority, in accordance
with such instructions. Without prejudice to the generality of the foregoing,
(i) each Agent shall be entitled to rely, and shall be fully protected in
relying, upon any communication, instrument or document believed by it to be
genuine and correct and to have been signed or sent by the proper person or
persons, and shall be entitled to rely and shall be protected in relying on
opinions and judgments of attorneys (who may be attorneys for Company and its
Subsidiaries), accountants, experts and other professional advisors selected by
it; and (ii) no Lender shall have any right of action whatsoever against any
Agent as a result of such Agent acting or (where so instructed) refraining from
acting hereunder or any of the other Credit Documents in accordance with the
instructions of Requisite Lenders (or such other Lenders as may be required to
give such instructions under Section 10.5).

         9.4. AGENTS ENTITLED TO ACT AS LENDER. The agency hereby created shall
in no way impair or affect any of the rights and powers of, or impose any duties
or obligations upon, any Agent in its individual capacity as a Lender hereunder.
With respect to its participation in the Loans, each Agent shall have the same
rights and powers hereunder as any other Lender and may exercise the same as
though it were not performing the duties and functions delegated to it
hereunder, and the term "LENDER" shall, unless the context clearly otherwise
indicates, include each Agent in its individual capacity. Any Agent and its
Affiliates may accept deposits from, lend money to and generally engage in any
kind of banking, trust, financial advisory or other business with Borrower or
any of its Affiliates as if it were not performing the duties specified herein,
and may accept fees and other consideration from Borrower for services in
connection herewith and otherwise without having to account for the same to
Lenders.


                                       92
<PAGE>   99

         9.5. LENDERS' AGREEMENTS. Each Lender agrees that it has made its own
independent investigation of the financial condition and affairs of Company and
its Subsidiaries in connection with Loans hereunder and that it has made and
shall continue to make its own appraisal of the creditworthiness of Company and
its Subsidiaries. No Agent shall have any duty or responsibility, either
initially or on a continuing basis, to make any such investigation or any such
appraisal on behalf of Lenders or to provide any Lender with any credit or other
information with respect thereto, whether coming into its possession before the
making of the Loans or at any time or times thereafter, and no Agent shall have
any responsibility with respect to the accuracy of or the completeness of any
information provided to Lenders.

         9.6. RIGHT TO INDEMNITY. Each Lender, in proportion to its Pro Rata
Share, severally agrees to indemnify each Agent, to the extent that such Agent
shall not have been reimbursed by Borrower, for and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses (including counsel fees and disbursements) or disbursements of
any kind or nature whatsoever which may be imposed on, incurred by or asserted
against such Agent in exercising its powers, rights and remedies or performing
its duties hereunder or under the other Credit Documents or otherwise in its
capacity as such Agent in any way relating to or arising out hereof or the other
Credit Documents; provided, no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from such Agent's gross negligence or
willful misconduct. If any indemnity furnished to any Agent for any purpose
shall, in the opinion of such Agent, be insufficient or become impaired, such
Agent may call for additional indemnity and cease, or not commence, to do the
acts indemnified against until such additional indemnity is furnished; provided,
in no event shall this sentence require any Lender to indemnify any Agent
against any liability, obligation, loss, damage, penalty, action, judgment,
suit, cost, expense or disbursement in excess of such Lender's Pro Rata Share
thereof; and provided further, this sentence shall not be deemed to require any
Lender to indemnify any Agent against any liability, obligation, loss, damage,
penalty, action, judgment, suit, cost, expense or disbursement described in the
proviso in the immediately preceding sentence.

         9.7. SUCCESSOR ADMINISTRATIVE AGENT. Administrative Agent may resign at
any time by giving thirty (30) days' prior written notice thereof to Lenders and
Borrower. Upon any such notice of resignation, Requisite Lenders shall have the
right, with the consent of Borrower (which shall not be unreasonably withheld or
delayed or required at any time an Event of Default shall have occurred and then
be continuing), to appoint a successor Administrative Agent. Upon the acceptance
of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, that successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent and the retiring Administrative Agent shall
be discharged from its duties and obligations hereunder. After any retiring
Administrative Agent's resignation hereunder as Administrative Agent, the
provisions of this Section 9 shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Agent hereunder.

         9.8. COLLATERAL DOCUMENTS AND GUARANTIES. (a) Each Lender hereby
further authorizes Administrative Agent, on behalf of and for the benefit of
Lenders, to be the agent for and


                                       93
<PAGE>   100

representative of Lenders with respect to the Guaranty, the Collateral and the
Collateral Documents. Subject to Section 10.5, without further written consent
or authorization from Lenders, Administrative Agent may execute any documents or
instruments necessary to (i) release any Lien encumbering any item of Collateral
that is the subject of a sale or other disposition of assets permitted hereby or
to which Requisite Lenders (or such other Lenders as may be required to give
such consent under Section 10.5) have otherwise consented or (ii) release any
Guarantor from the Guaranty pursuant to Section 7.13 or with respect to which
Requisite Lenders (or such other Lenders as may be required to give such consent
under Section 10.5) have otherwise consented.

         (b) Anything contained in any of the Credit Documents to the contrary
notwithstanding, each Credit Party, Administrative Agent and each Lender hereby
agree that (i) no Lender shall have any right individually to realize upon any
of the Collateral or to enforce the Guaranty, it being understood and agreed
that all powers, rights and remedies hereunder may be exercised solely by
Administrative Agent for the benefit of Lenders in accordance with the terms
hereof, and (ii) in the event of a foreclosure by Administrative Agent on any of
the Collateral pursuant to a public or private sale, Administrative Agent or any
Lender may be the purchaser of any or all of such Collateral at any such sale
and Administrative Agent, as agent for and representative of Lenders (but not
any Lender or Lenders in its or their respective individual capacities unless
Requisite Lenders shall otherwise agree in writing) shall be entitled, for the
purpose of bidding and making settlement or payment of the purchase price for
all or any portion of the Collateral sold at any such public sale, to use and
apply any of the Obligations as a credit on account of the purchase price for
any collateral payable by Administrative Agent at such sale.

         (c) It is the purpose hereof and the other Credit Documents that there
shall be no violation of any law of any jurisdiction denying or restricting the
right of banking corporations or associations to transact business as agent or
trustee in such jurisdiction. It is recognized that in case of litigation
hereunder or any of the other Credit Documents, and in particular in case of the
enforcement of any of the Credit Documents, or in case Administrative Agent
deems that by reason of any present or future law of any jurisdiction it may not
exercise any of the rights, powers or remedies granted herein or in any of the
other Credit Documents or take any other action which may be desirable or
necessary in connection therewith, it may be necessary that Administrative Agent
appoint an additional individual or institution as a separate trustee,
co-trustee, collateral agent or collateral co-agent (a "SUPPLEMENTAL COLLATERAL
AGENT"). In the event that Administrative Agent appoints a Supplemental
Collateral Agent with respect to any Collateral, (i) each and every right,
power, privilege or duty expressed or intended hereby or any of the other Credit
Documents to be exercised by or vested in or conveyed to Administrative Agent
with respect to such Collateral shall be exercisable by and vest in such
Supplemental Collateral Agent to the extent, and only to the extent, necessary
to enable such Supplemental Collateral Agent to exercise such rights, powers and
privileges with respect to such Collateral and to perform such duties with
respect to such Collateral, and every covenant and obligation contained in the
Credit Documents and necessary to the exercise or performance thereof by such
Supplemental Collateral Agent shall run to and be enforceable by either Agent or
such Supplemental Collateral Agent, and (ii) the provisions of this Section 9
and of Sections 10.2 and 10.3 that refer to Administrative Agent shall inure to
the benefit of such


                                       94
<PAGE>   101

Supplemental Collateral Agent and all references therein to Administrative Agent
shall be deemed to be references to Administrative Agent and/or such
Supplemental Collateral Agent, as the context may require. Should any instrument
in writing from Borrower or any other Credit Party be required by any
Supplemental Collateral Agent so appointed by Administrative Agent for more
fully and certainly vesting in and confirming to him or it such rights, powers,
privileges and duties, Borrower shall, or shall cause such Credit Party to,
execute, acknowledge and deliver any and all such instruments promptly upon
request by Administrative Agent. In case any Supplemental Collateral Agent, or a
successor thereto, shall die, become incapable of acting, resign or be removed,
all the rights, powers, privileges and duties of such Supplemental Collateral
Agent, to the extent permitted by law, shall vest in and be exercised by
Administrative Agent until the appointment of a new Supplemental Collateral
Agent.

SECTION 10.  MISCELLANEOUS

         10.1. NOTICES. Unless otherwise specifically provided herein, any

notice to any Agent or Lender shall be effective until received by such Agent or
Lender.

         10.2. EXPENSES. Whether or not the transactions contemplated hereby
shall be consummated, Borrower agrees to pay promptly (a) all the reasonable out
of pocket costs and expenses of each Agent associated with the syndication of
the credit facilities hereunder and the preparation, execution and delivery of
the Credit Documents and any consents, amendments, waivers or other
modifications thereto; (b) all reasonable costs of furnishing all opinions by
counsel for any Credit Party (including any opinions requested by Lenders as to
any legal matters arising hereunder) and of Borrower's and each Credit Party's

be performed or complied with hereunder and the other Credit Documents including
with respect to confirming compliance with environmental, insurance and solvency

accountants, consultants or appraisers; (f) all the reasonable out of pocket
costs and expenses (including the reasonable fees, expenses and disbursements of
any appraisers, consultants, advisors and agents employed or retained by
Administrative Agent and its counsel) in connection with the custody or
preservation of any of the Collateral; (g) all other reasonable out of pocket
costs and expenses incurred by each Agent in connection with the syndication of
the Loans and Commitments and the negotiation, preparation and execution of the
Credit Documents and any consents, amendments, waivers or other modifications
thereto and the transactions contemplated thereby; and (h) after the occurrence
or an Event of Default, all costs and expenses, including reasonable attorneys'
fees and costs of settlement, incurred by any Agent and Lenders in enforcing any
Obligations of or in collecting any payments due from any Credit Party hereunder
or under the other Credit Documents by reason of such Event of Default
(including in connection with the sale of, collection from, or other realization
upon any of the Collateral or the enforcement of the Guaranty) or in connection
with any refinancing or restructuring of the credit arrangements provided
hereunder in the nature of a "work-out" or pursuant to any insolvency or
bankruptcy proceedings.

         10.3. INDEMNITY. In addition to the payment of expenses pursuant to
Section 10.2, whether or not the transactions contemplated hereby shall be
consummated, each Credit Party agrees to defend (subject to Indemnitees'
selection of counsel), indemnify, pay and hold harmless, each Agent and Lender
and the officers, partners, directors, trustees, employees, agents and
Affiliates of each Agent and each Lender (each, an "INDEMNITEE"), from and
against any and all Indemnified Liabilities; provided, no Credit Party shall
have any obligation to any Indemnitee hereunder with respect to any Indemnified
Liabilities to the extent such Indemnified Liabilities arise from the gross
negligence, willful misconduct or bad faith of that Indemnitee as determined by
a final, non-appealable judgment of a court of competent jurisdiction. To the
extent that the undertakings to defend, indemnify, pay and hold harmless set
forth in this Section 10.3 may be unenforceable in whole or in part because they
are violative of any law or public policy, the applicable Credit Party shall
contribute the maximum portion that it is permitted to pay and satisfy under
applicable law to the payment and satisfaction of all Indemnified Liabilities
incurred by Indemnitees or any of them.

         10.4. SET-OFF. In addition to any rights now or hereafter granted under
applicable law and not by way of limitation of any such rights, upon the
occurrence and during the continuance of any Event of Default each Lender is
hereby authorized by each Credit Party at any time or from time to time subject
to the consent of Administrative Agent (such consent not to be unreasonably
withheld or delayed), without notice to any Credit Party or to any other Person
(other than Administrative Agent), any such notice being hereby expressly
waived, to set off and to appropriate and to apply any and all deposits (general
or special, including Indebtedness evidenced by certificates of deposit, whether
matured or unmatured, but not including trust accounts) and any other
Indebtedness at any time held or owing by such Lender to or for the credit or
the account of any Credit Party against and on account of the obligations and
liabilities of any Credit Party due and payable to such Lender hereunder and the
other Credit Documents, including all claims of any nature or description
arising out of or connected herewith, or any other Credit Document, irrespective
of whether or not (a) such Lender shall have made any demand hereunder or (b)
the principal of or the interest on the Loans or


                                       96
<PAGE>   103

any other amounts due hereunder shall have become due and payable pursuant to
Section 2 and although said obligations and liabilities, or any of them, may be
contingent or unmatured. Each Credit Party hereby further grants to
Administrative Agent and each Lender a security interest in all Deposit Accounts
maintained with Administrative Agent or such Lender as security for the
Obligations.

         10.5. AMENDMENTS AND WAIVERS. (a) Subject to Section 10.5(b) and
10.5(c), no amendment, modification, termination or waiver of any provision of
the Credit Documents, or consent to any departure by any Credit Party therefrom,
shall in any event be effective without the written concurrence of the Requisite
Lenders.

         (b) Without the written consent of each Lender that would be affected
thereby, no amendment, modification, termination, or consent shall be effective
if the effect thereof would:

                  (i) extend the scheduled final maturity of any Loan or Note;

                  (ii) waive, reduce or postpone any scheduled reduction;

                  (iii) reduce the rate of interest on any Loan (other than any
         waiver of any increase in the interest rate applicable to any Loan
         pursuant to Section 2.7) or any fee payable hereunder;

                  (iv) extend the time for payment of any such interest or fees;

                  (v) reduce the principal amount of any Loan;

                  (vi) amend, modify, terminate or waive any provision of this
         Section 10.5(b);

of the Credit Documents, or consent to any departure by any Credit Party
therefrom, shall:

                  (i) increase any Commitment of any Lender over the amount
         thereof then in effect without the consent of such Lender; provided, no
         amendment, modification or waiver of any condition precedent, covenant,
         Default or Event of Default shall constitute an increase in any
         Commitment of any Lender; or


                                       97

<PAGE>   104

                  (ii) amend, modify, terminate or waive any provision of
         Section 9 as the same applies to any Agent, or any other provision
         hereof as the same applies to the rights or obligations of any Agent,
         in each case without the consent of such Agent.

         (d) Administrative Agent may, but shall have no obligation to, with the
concurrence of any Lender, execute amendments, modifications, waivers or
consents on behalf of such Lender. Any waiver or consent shall be effective only
in the specific instance and for the specific purpose for which it was given. No
notice to or demand on any Credit Party in any case shall entitle any Credit
Party to any other or further notice or demand in similar or other
circumstances. Any amendment, modification, termination, waiver or consent
effected in accordance with this Section 10.5 shall be binding upon each Lender
at the time outstanding, each future Lender and, if signed by a Credit Party, on
such Credit Party.

         10.6. SUCCESSORS AND ASSIGNS; PARTICIPATIONS. (a) This Agreement shall
be binding upon the parties hereto and their respective successors and assigns
and shall inure to the benefit of the parties hereto and the successors and
assigns of Lenders. No Credit Party's rights or obligations hereunder nor any
interest therein may be assigned or delegated by any Credit Party without the
prior written consent of all Lenders.

         (b) Borrower, Administrative Agent and Lenders shall deem and treat the
Persons listed as Lenders in the Register as the holders and owners of the
corresponding Commitments and Loans listed therein for all purposes hereof, and
no assignment or transfer of any such Commitment or Loan shall be effective
unless and until an Assignment Agreement effecting the assignment or transfer
thereof shall have been delivered to Administrative Agent and recorded in the
Register. Prior to such recordation, all amounts owed with respect to the
applicable Commitment or Loan shall be owed to the Lender listed in the Register
as the owner thereof, and any request, authority or consent of any Person who,
at the time of making such request or giving such authority or consent, is
listed in the Register as a Lender shall be conclusive and binding on any
subsequent holder, assignee or transferee of the corresponding Commitments or
Loans.

         (c) Each Lender shall have the right at any time to sell, assign or
transfer any Commitment, any Loan or any other Obligation:

                  (i) to any Person meeting the criteria of clause (i) of the
         definition of the term of "ELIGIBLE ASSIGNEE" upon the giving of notice
         to Borrower and Administrative Agent; and

                  (ii) to any Person meeting the criteria of clause (ii) of the
         definition of the term of "Eligible Assignee" upon the consent of each
         of Borrower and Administrative Agent (neither of which shall be
         unreasonably withheld or delayed or shall be required at any time an
         Event of Default shall have occurred and then be continuing); provided,
         each such assignment pursuant to this Section 10.6(c)(ii) shall be in
         an aggregate amount of not less than $5,000,000 and after giving effect
         thereto the assigning Lender must have Commitments and Loans
         aggregating at least $5,000,000 (or such lesser amount as may be agreed


                                       98
<PAGE>   105

         to by Borrower and Administrative Agent or as shall constitute the
         aggregate amount of the Commitments, Loans and other Obligations of the
         assigning Lender).

         (d) The assigning Lender and the assignee thereof shall execute and
deliver to Administrative Agent an Assignment Agreement, together with (i) a
processing and recordation fee of $3,500 (which shall not be due in the case of
assignments to an Affiliate of the assigning Lender, and which shall be $750 in
the case of assignments by GSCP), and (ii) such forms, certificates or other
evidence, if any, with respect to United States federal income tax withholding
matters as the assignee under such Assignment Agreement may be required to
deliver to Administrative Agent and Borrower pursuant to Section 2.18(c).

         (e) Upon its receipt of a duly executed and completed Assignment
Agreement, together with the processing and recordation fee referred to in
Section 10.6(d) (and any forms, certificates or other evidence required by this
Agreement in connection therewith), Administrative Agent shall record the
information contained in such Assignment Agreement in the Register, shall give
prompt notice thereof to Borrower and shall maintain a copy of such Assignment
Agreement.

         (f) Each Lender, upon execution and delivery hereof or upon executing
and delivering an Assignment Agreement, as the case may be, represents and
warrants as of the Closing Date or as of the applicable Effective Date (as
defined in the applicable Assignment Agreement) that (i) it is an Eligible
Assignee; (ii) it has experience and expertise in the making of or investing in
commitments or loans such as the Commitments or Loans, as the case may be; and
(iii) it will make or invest in, as the case may be, its Commitments or Loans
for its own account in the ordinary course of its business and without a view to
distribution of such Commitments or Loans within the meaning of the Securities
Act or the Exchange Act or other federal securities laws (it being understood
that, subject to the provisions of this Section 10.6, the disposition of such
Commitments or Loans or any interests therein shall at all times remain within
its exclusive control).

         (g) Subject to the terms and conditions of this Section 10.6, as of the
"Effective Date" specified in such Assignment Agreement: (i) the assignee
thereunder shall have the rights and obligations of a "Lender" hereunder to the
extent such rights and obligations hereunder have been assigned to it pursuant
to such Assignment Agreement and shall thereafter be a party hereto and a
"Lender" for all purposes hereof; (ii) the assigning Lender thereunder shall, to
the extent that rights and obligations hereunder have been assigned thereby
pursuant to such Assignment Agreement, relinquish its rights (other than any
rights which survive the termination hereof under Section 10.8) and be released
from its obligations hereunder (and, in the case of an Assignment Agreement
covering all or the remaining portion of an assigning Lender's rights and
obligations hereunder, such Lender shall cease to be a party hereto); (iii) the
Commitments shall be modified to reflect the Commitment of such assignee and any
remaining Commitment of such assigning Lender, if any; and (iv) if any such
assignment occurs after the issuance of any Note hereunder, the assigning Lender
shall, upon the effectiveness of such assignment or as promptly thereafter as
practicable, surrender its applicable Notes to Administrative Agent for
cancellation, and thereupon Borrower shall issue and deliver new Notes, if so
requested by the assignee and/or assigning Lender, to such assignee


                                       99
<PAGE>   106

and/or to such assigning Lender, with appropriate insertions, to reflect the new
Commitments and/or outstanding Loans of the assignee and/or the assigning
Lender.

         (h) Each Lender shall have the right at any time to sell one or more
participations to any Person in all or any part of its Commitments, Loans or in
any other Obligation. The holder of any such participation, other than an
Affiliate of the Lender granting such participation, shall not be entitled to
require such Lender to take or omit to take any action hereunder except with
respect to any amendment modification or waiver described in Section 10.5(b) or
10.5(c) to the extent directly affecting the Loan or Commitment relating to the
participation. All amounts payable by any Credit Party hereunder, including
amounts payable to such Lender pursuant to Section 2.16(c), 2.17 or 2.18, shall
be determined as if such Lender had not sold such participation. Each Credit
Party and each Lender hereby acknowledge and agree that, solely for purposes of
Sections 2.15 and 10.4, (1) any participation will give rise to a direct
obligation of each Credit Party to the participant and (2) the participant shall
be considered to be a "Lender".

         (i) In addition to any other assignment permitted pursuant to this
Section 10.6, (i) any Lender may assign and pledge all or any portion of its
Loans, the other Obligations owed to such Lender, and its Notes to any Federal
Reserve Bank as collateral security pursuant to Regulation A of the Board of
Governors of the Federal Reserve System and any operating circular issued by
such Federal Reserve Bank, and (ii) with the consent of Borrower and
Administrative Agent any Lender which is an investment fund may pledge all or
any portion of its Notes or Loans to its trustee in support of its obligations
to such trustee; provided, no Lender, as between Borrower and such Lender, shall
be relieved of any of its obligations hereunder as a result of any such
assignment and pledge, and provided further, in no event shall the applicable
Federal Reserve Bank or trustee be considered to be a "Lender" or be entitled to
require the assigning Lender to take or omit to take any action hereunder.

         10.7. INDEPENDENCE OF COVENANTS. All covenants hereunder shall be given
independent effect so that if a particular action or condition is not permitted
by any of such covenants, the fact that it would be permitted by an exception
to, or would otherwise be within the limitations of, another covenant shall not
avoid the occurrence of a Default or an Event of Default if such action is taken
or condition exists.

         10.8. SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS. All
representations, warranties and agreements made herein shall survive the
execution and delivery hereof and the making of any Loan. Notwithstanding
anything herein or implied by law to the contrary, the agreements of each Credit
Party set forth in Sections 2.16(c), 2.17, 2.18, 7.2, 10.2, 10.3 and 10.4 and
the agreements of Lenders set forth in Sections 2.15 and 9.6 shall survive the
payment of the Loans.

         10.9. NO WAIVER; REMEDIES CUMULATIVE. No failure or delay on the part
of Administrative Agent or any Lender in the exercise of any power, right or
privilege hereunder or under any other Credit Document shall impair such power,
right or privilege or be construed to be a waiver of any default or acquiescence
therein, nor shall any single or partial exercise of any such power, right or


                                      100
<PAGE>   107

privilege preclude other or further exercise thereof or of any other power,
right or privilege. The rights, powers and remedies given to each Agent and each
Lender hereby are cumulative and shall be in addition to and independent of all
rights, powers and remedies existing by virtue of any statute or rule of law or
in any of the other Credit Documents or any Hedge Agreement. Any forbearance or
failure to exercise, and any delay in exercising, any right, power or remedy
hereunder shall not impair any such right, power or remedy or be construed to be
a waiver thereof, nor shall it preclude the further exercise of any such right,
power or remedy.

         10.10. MARSHALLING; PAYMENTS SET AIDE. Neither Administrative Agent nor
any Lender shall be under any obligation to marshal any assets in favor of any
Credit Party or any other Person or against or in payment of any or all of the
Obligations. To the extent that any Credit Party makes a payment or payments to
Administrative Agent or Lenders (or to Administrative Agent for the benefit of
Lenders), or Administrative Agent or Lenders enforce any security interests or
exercise their rights of setoff, and such payment or payments or the proceeds of
such enforcement or setoff or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside and/or required to be
repaid to a trustee, receiver or any other party under any bankruptcy law, any
other state or federal law, common law or any equitable cause, then, to the
extent of such recovery, the obligation or part thereof originally intended to
be satisfied, and all Liens, rights and remedies therefor or related thereto,
shall be revived and continued in full force and effect as if such payment or
payments had not been made or such enforcement or setoff had not occurred.

         10.11. SEVERABILITY. In case any provision in or obligation hereunder
or any Note shall be invalid, illegal or unenforceable in any jurisdiction, the
validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby.

         10.12. OBLIGATIONS SEVERAL; INDEPENDENT NATURE OF LENDERS' RIGHTS. The
obligations of Lenders hereunder are several and no Lender shall be responsible
for the obligations or Commitments of any other Lender hereunder. Nothing
contained herein or in any other Credit Document, and no action taken by Lenders
pursuant hereto or thereto, shall be deemed to constitute Lenders as a
partnership, an association, a joint venture or any other kind of entity. The
amounts payable at any time hereunder to each Lender shall be a separate and
independent debt, and each Lender shall be entitled to protect and enforce its
rights arising out hereof and it shall not be necessary for any other Lender to
be joined as an additional party in any proceeding for such purpose.

         10.13. HEADINGS. Section headings herein are included herein for
convenience of reference only and shall not constitute a part hereof for any
other purpose or be given any substantive effect.

         10.14. APPLICABLE LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (INCLUDING SECTION 5-1401
OF THE GENERAL


                                       101
<PAGE>   108

OBLIGATIONS LAW OF THE STATE OF NEW YORK), WITHOUT REGARD TO CONFLICT OF LAWS
PRINCIPLES THEREOF.

         10.15. CONSENT TO JURISDICTION. ALL JUDICIAL PROCEEDINGS BROUGHT
AGAINST ANY CREDIT PARTY ARISING OUT OF OR RELATING HERETO OR ANY OTHER CREDIT
DOCUMENT, OR ANY OF THE OBLIGATIONS, MAY BE BROUGHT IN ANY STATE OR FEDERAL
COURT OF COMPETENT JURISDICTION IN THE STATE, COUNTY AND CITY OF NEW YORK. BY
EXECUTING AND DELIVERING THIS AGREEMENT, EACH CREDIT PARTY, FOR ITSELF AND IN
CONNECTION WITH ITS PROPERTIES, IRREVOCABLY (A) ACCEPTS GENERALLY AND
UNCONDITIONALLY THE NONEXCLUSIVE JURISDICTION AND VENUE OF SUCH COURTS; (B)
WAIVES ANY DEFENSE OF FORUM NON CONVENIENS; (C) AGREES THAT SERVICE OF ALL
PROCESS IN ANY SUCH PROCEEDING IN ANY SUCH COURT MAY BE MADE BY REGISTERED OR
CERTIFIED MAIL, RETURN RECEIPT REQUESTED, TO THE APPLICABLE CREDIT PARTY AT ITS
ADDRESS PROVIDED IN ACCORDANCE WITH SECTION 10.1; (D) AGREES THAT SERVICE AS
PROVIDED IN CLAUSE (C) ABOVE IS SUFFICIENT TO CONFER PERSONAL JURISDICTION OVER
THE APPLICABLE CREDIT PARTY IN ANY SUCH PROCEEDING IN ANY SUCH COURT, AND
OTHERWISE CONSTITUTES EFFECTIVE AND BINDING SERVICE IN EVERY RESPECT; AND (E)
AGREES SUCH LENDERS RETAIN THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW OR TO BRING PROCEEDINGS AGAINST ANY CREDIT PARTY IN THE COURTS
OF ANY OTHER JURISDICTION.

         10.16. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY AGREES
TO WAIVE ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING OUT HEREOF OR ANY OF THE OTHER CREDIT DOCUMENTS OR ANY
DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS LOAN TRANSACTION OR
THE LENDER/ BORROWER RELATIONSHIP THAT IS BEING ESTABLISHED. THE SCOPE OF THIS
WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE
FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS TRANSACTION,
INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS AND ALL OTHER
COMMON LAW AND STATUTORY CLAIMS. EACH PARTY HERETO ACKNOWLEDGES THAT THIS WAIVER
IS A MATERIAL INDUCEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT EACH HAS
ALREADY RELIED ON THIS WAIVER IN ENTERING INTO THIS AGREEMENT, AND THAT EACH
WILL CONTINUE TO RELY ON THIS WAIVER IN THEIR RELATED FUTURE DEALINGS. EACH
PARTY HERETO FURTHER WARRANTS AND REPRESENTS THAT IT HAS REVIEWED THIS WAIVER
WITH ITS LEGAL COUNSEL AND THAT IT KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY
TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. THIS WAIVER IS
IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER


                                      102
<PAGE>   109

ORALLY OR IN WRITING (OTHER THAN BY A MUTUAL WRITTEN WAIVER SPECIFICALLY
REFERRING TO THIS SECTION 10.16 AND EXECUTED BY EACH OF THE PARTIES HERETO), AND
THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
MODIFICATIONS HERETO OR ANY OF THE OTHER CREDIT DOCUMENTS OR TO ANY OTHER
DOCUMENTS OR AGREEMENTS RELATING TO THE LOANS MADE HEREUNDER. IN THE EVENT OF
LITIGATION, THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE
COURT.

         10.17. CONFIDENTIALITY. Each Lender shall hold all non-public
information obtained pursuant to the requirements hereof in accordance with such
Lender's customary procedures for handling confidential information of this
nature and in accordance with prudent lending or investing practices, it being
understood and agreed by Company that in any event a Lender may make disclosures
to Affiliates of such Lender or disclosures reasonably required by any bona fide
or potential assignee, transferee or participant in connection with the
contemplated assignment, transfer or participation by such Lender of any Loans
or any participations therein or by any direct or indirect contractual
counterparties (or the professional advisors thereto) in swap agreements
(provided, such Affiliates, assignees, transferees, participants, swap
counterparties and advisors are advised of and agree to be bound by the
provisions of this Section 10.17) or disclosures required or requested by any
governmental agency or representative thereof or by the National Association of
Insurance Commissioners or pursuant to legal process; provided, unless
prohibited by applicable law or court order, each Lender shall notify Company of
any request by any governmental agency or representative thereof (other than any
such request in connection with any examination of the financial condition of
such Lender by such governmental agency) for disclosure of any such non-public
information prior to disclosure of such information; and provided further, in no
event shall any Lender be obligated or required to return any materials
furnished by Company or any of its Subsidiaries.

         10.18. USURY SAVINGS CLAUSE. Notwithstanding any other provision
herein, the aggregate interest rate charged with respect to any of the
Obligations, including all charges or fees in connection therewith deemed in the
nature of interest under applicable law shall not exceed the Highest Lawful
Rate. If the rate of interest (determined without regard to the preceding
sentence) under this Agreement at any time exceeds the Highest Lawful Rate, the
outstanding amount of the Loans made hereunder shall bear interest at the
Highest Lawful Rate until the total amount of interest due hereunder equals the
amount of interest which would have been due hereunder if the stated rates of
interest set forth in this Agreement had at all times been in effect. In
addition, if when the Loans made hereunder are repaid in full the total interest
due hereunder (taking into account the increase provided for above) is less than
the total amount of interest which would have been due hereunder if the stated
rates of interest set forth in this Agreement had at all times been in effect,
then to the extent permitted by law, Borrower shall pay to Administrative Agent
an amount equal to the difference between the amount of interest paid and the
amount of interest which would have been paid if the Highest Lawful Rate had at
all times been in effect. Notwithstanding the foregoing, it is the intention of
Lenders and Borrower to conform strictly to any applicable usury laws.
Accordingly,


                                      103
<PAGE>   110

if any Lender contracts for, charges, or receives any consideration which
constitutes interest in excess of the Highest Lawful Rate, then any such excess
shall be canceled automatically and, if previously paid, shall at such Lender's
option be applied to the outstanding amount of the Loans made hereunder or be
refunded to Borrower.

         10.19. COUNTERPARTS; EFFECTIVENESS. This Agreement may be executed in
any number of counterparts, each of which when so executed and delivered shall
be deemed an original, but all such counterparts together shall constitute but
one and the same instrument. This Agreement shall become effective upon the
execution of a counterpart hereof by each of the parties hereto and receipt by
Borrower and Administrative Agent of written or telephonic notification of such
execution and authorization of delivery thereof.

            [The remainder of this page is intentionally left blank.]

                              ASSIGNMENT AGREEMENT

         This ASSIGNMENT AGREEMENT (this "Agreement"), dated as of the date set
forth on Schedule I hereto as the Effective Date (the "Effective Date"), by and
between the parties signatory hereto and designated as Assignor ("Assignor") and
Assignee ("Assignee").


                                    RECITALS:

         WHEREAS, Assignor is party to the Credit and Guaranty Agreement, dated
as of April __, 1999 (as it may be amended, supplemented or otherwise modified,
the "Credit Agreement"; the terms defined therein and not otherwise defined
herein being used herein as therein defined), by and among Allegiance Telecom,
Inc. ("Company"), Allegiance Finance Company, Inc. ("Borrower"), the
Subsidiaries of Company (other than Borrower) party thereto, as Guarantors,
Lenders, Goldman Sachs Credit Partners L.P. ("GSCP"), as Syndication Agent,
Toronto Dominion (Texas), Inc., as Administrative Agent, Morgan Stanley Senior

Co-Lead Arrangers; and

         WHEREAS, Assignor desires to sell and assign to Assignee, and Assignee
desires to purchase and assume from Assignor, certain rights and obligations of
Assignor under the Credit Agreement.

         NOW, THEREFORE, in consideration of the agreements and covenants herein
contained, the parties hereto agree as follows:

         Section 1. Assignment and Assumption. Subject to the terms and
conditions hereof, as of the Effective Date, Assignor sells and assigns to
Assignee, without recourse, representation or warranty (except as expressly set
forth herein), and Assignee purchases and assumes from Assignor, the percentage
interest specified on Schedule I hereto in all of the rights and obligations
with respect to the Commitments and outstanding Loans of Lenders arising under
the Credit Agreement and the other Credit Documents (the "Assigned Share"). In
consideration of such assignment, Assignee hereby agrees to pay to Assignor, on
the date set forth on Schedule I hereto as the Settlement Date (the "Settlement
Date"), the principal amount of any outstanding loans included within the
Assigned Share (such principal amount referred to herein as the "Purchase
Price"), such payment to be made by wire transfer of immediately available
funds. Upon the occurrence of the Effective Date: (a) the Assignee shall have
the rights and obligations of a Lender to the extent of the Assigned Share and
shall thereafter be a party to the Credit Agreement and a Lender for all
purposes of the Credit Documents; (b) Assignor shall, to the extent of the
Assigned Share, relinquish its rights (other than any rights which survive the


                                       E-1

<PAGE>   149

payment of the Loans under Section 10.8 thereof) and be released from its
obligations under the Credit Agreement; and (c) the Commitments shall be
modified to reflect the Commitment of Assignee and any remaining Commitment of
Assignor. From and after the Effective Date, Administrative Agent shall make
all payments under the Credit Agreement in respect of the Assigned Share (i) in
the case of any interest and fees that shall have accrued prior to the
Settlement Date, to Assignor, and (ii) in all other cases, to Assignee;
provided, Assignor and Assignee shall make payments directly to each other to
the extent necessary to effect any appropriate adjustments in any amounts
distributed to Assignor and/or Assignee by Administrative Agent under the Credit
Documents in respect of the Assigned Share in the event that, for any reason
whatsoever, the payment of consideration contemplated by this Section 1 occurs
on a date other than the Settlement Date.

         Section 2. Effective Date. Notwithstanding anything herein to the
contrary, the Effective Date shall not be deemed to have occurred until each of
the following conditions are satisfied, as determined in the reasonable judgment
of each of Assignor, Assignee and Administrative Agent: (a) the execution of a
counterpart hereof by each of Assignor and Assignee; (b) the payment of the
Purchase Price on the Settlement Date; (c) the receipt by Administrative Agent
of the processing and recordation fee referred to in Section 10.6(d) of the
Credit Agreement; (d) in the event Assignee is a Non-US Lender, the delivery by
Assignee to Administrative Agent of such forms, certificates or other evidence
with respect to United States federal income tax withholding matters as Assignee
may be required to deliver to Administrative Agent pursuant to Section 2.18(c);
(e) the receipt by Administrative Agent of originals or telefacsimiles of
executed counterparts hereof; and (f) the recordation by Administrative Agent in
the Register of the pertinent information regarding this Assignment pursuant to
Section 10.6(e) of the Credit Agreement.

         Section 3. Certain Representations, Warranties and Agreements. (a)
Assignor represents and warrants to Assignee that (i) Assignor is the legal and
beneficial owner of the Assigned Share, free and clear of any adverse claim; and
(ii) Schedule I hereto sets forth the aggregate amount of the Commitments and
the aggregate amount of the Loans, in each case as of the Effective Date.

         (b) Assignee represents and warrants to Assignor that (i) it is an
Eligible Assignee and that it has experience and expertise in the making or
purchasing of loans and commitment such as the Loans and the Commitments; (ii)
it has acquired the Assigned Share for its own account in the ordinary course of
its business and without a view to distribution of the Loans within the meaning
of the Securities Act or the Exchange Act or other federal securities laws (it
being understood that, subject to the provisions of Section 10.6 of the Credit
Agreement, the disposition of the Assigned Share or any interests therein shall
at all times remain within its exclusive control); (iii) it has received,
reviewed and approved a copy of the Credit Agreement (including all Exhibits and
Schedules thereto); and (iv) it has received from Assignor such financial
information regarding Company and its Subsidiaries as is available to Assignor
and as Assignee has requested, that it has made its own independent
investigation of the financial


                                      E-2
<PAGE>   150

condition and affairs of Company and its Subsidiaries in connection with the
assignment evidenced by this Agreement, and that it has made and shall continue
to make its own appraisal of the creditworthiness of Company and its
Subsidiaries. Assignor shall have no duty or responsibility, either initially or
on a continuing basis, to make any such investigation or any such appraisal on
behalf of Assignee or to provide Assignee with any other credit or other
information with respect thereto, whether coming into its possession before the
making of the initial Loans or at any time or times thereafter, and Assignor
shall not have any responsibility with respect to the accuracy of or the
completeness of any information provided to Assignee.

         (c) Each party to this Agreement represents and warrants to the other
party hereto that it has full power and authority to enter into this Agreement
and to perform its obligations hereunder in accordance with the provisions
hereof, that this Agreement has been duly authorized, executed and delivered by
such party and that this Agreement constitutes a legal, valid and binding
obligation of such party, enforceable against such party in accordance with its
terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws affecting
creditors' rights generally and by general principles of equity.

         (d) Assignor shall not be responsible to Assignee for the execution,
effectiveness, genuineness, validity, enforceability, collectibility or
sufficiency of any of the Credit Documents or for any representations,
warranties, recitals or statements made therein or made in any written or oral
statements or in any financial or other statements, instruments, reports or
certificates or any other documents furnished or made by Assignor to Assignee or
by or on behalf of Company or any of its Subsidiaries to Assignor or Assignee in
connection with the Credit Documents and the transactions contemplated thereby
or for the financial condition or business affairs of Company or any other
Person liable for the payment of any Obligations, nor shall Assignor be required
to ascertain or inquire as to the performance or observance of any of the terms,
conditions, provisions, covenants or agreements contained in any of the Credit
Documents or as to the use of the proceeds of the Loans or as to the existence
or possible existence of any Event of Default or Default.

         Section 4. Miscellaneous. Assignor and Assignee each agrees from time
to time, upon request of such other party, to take such additional actions and
to execute and deliver such additional documents and instruments as such other
party may reasonably request to effect the transactions contemplated by, and to
carry out the intent of, this Agreement. Neither this Agreement nor any term
hereof may be changed, waived, discharged or terminated, except by an instrument
in writing signed by the party (including, if applicable, any party required to
evidence its consent to or acceptance of this Agreement) against whom
enforcement of such change, waiver, discharge or termination is sought. Any
notice or other communication herein required or permitted to be given shall be
given pursuant to Section 10.1 of the Credit Agreement, and all for purposes
thereof, the notice address of Assignee shall be the address as set forth on the
signature page hereof. In case any provision in or obligation under this
Agreement shall be invalid, illegal or unenforceable in any jurisdiction, the
validity, legality and enforceability of the


                                      E-3
<PAGE>   151

remaining provisions or obligations, or of such provision or obligation in any
other jurisdiction, shall not in any way be affected or impaired thereby. This
Agreement shall be binding upon, and shall inure to the benefit of, the parties
hereto and their respective successors and assigns. This Agreement may be
executed in one or more counterparts and by different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed an
original, but all such counterparts together shall constitute but one and the
same instrument; signature pages may be detached from multiple separate
counterparts and attached to a single counterpart so that all signature pages
are physically attached to the same document.

         THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER
SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND EN FORCED IN ACCORDANCE WITH,
THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICT OF LAWS

<PAGE>   167

Collateral and, to the extent not otherwise included, all payments under

Collateral or proceeds are sold, exchanged, collected or otherwise disposed of,
whether such disposition is voluntary or involuntary.

Notwithstanding anything herein to the contrary, in no event shall the
Collateral include, and no Grantor shall be deemed to have granted a security
interest in, any of such Grantor's rights or interests in any license, permit,
franchise, certification (including all regulatory certifications), contract or
agreement to which such Grantor is a party or a grantee or any of its rights or
interests thereunder to the extent, but only to the extent, that such a grant
would, under the terms of such license, permit, franchise, certification
(including all regulatory certifications), contract or agreement, applicable law
or regulation or otherwise, result in a breach of the terms of, or constitute a
default under any license, permit, franchise, certification (including all
regulatory certifications), contract or agreement to which such Grantor is a
party or under applicable law or regulation (other than to the extent that any
such term would be rendered ineffective pursuant to Section 9-318(4) of the
Uniform Commercial Code of any relevant jurisdiction or any other applicable law
(including the Bankruptcy Code) or principles of equity); provided, immediately
upon the ineffectiveness, lapse or termination of any such provision or law or
regulation, the Collateral shall include, and such Grantor shall be deemed to
have granted a security interest in, all such rights and interests as if such
provision or law or regulation had never been in effect.

SECTION 2. SECURITY FOR OBLIGATIONS; GRANTORS REMAIN LIABLE

         This Agreement secures, and the Collateral is collateral security for,
the prompt payment or performance in full when due, whether at stated maturity,
by required prepayment, declaration, acceleration, demand or otherwise
(including the payment of amounts that would become due but for the operation of
the automatic stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C.
Section 362(a)), of in the case of Collateral in which a security interest is
granted by (i) Company Grantor, all Obligations of Borrower and (ii) each
Subsidiary Grantor, all Obligations of such Subsidiary Grantor and each other
Subsidiary Grantor which is a Subsidiary of such Subsidiary Grantor (clauses (i)
and (ii) collectively, the "Secured Obligations"). Anything contained herein to
the contrary notwithstanding, (a) each Grantor shall remain liable under any
Partnership Agreement, LLC Agreement or any other contracts and agreements
included in the Collateral, to the extent set forth therein, to perform all of
its duties and obligations thereunder to the same extent as if this Agreement
had not been executed; (b) the exercise by Secured Party of any of its rights
hereunder shall not release any Grantor from any of its duties or obligations
under the contracts and agreements included in the Collateral; and (c) Secured
Party shall not have any obligation or liability under any Partnership
Agreement, LLC Agreement or any other contracts and agreements included in the
Collateral by reason of this Agreement, nor shall Secured Party be obligated to
perform any of the obligations or duties of any Grantor thereunder or to take
any action to collect or enforce any claim for payment assigned hereunder.
Notwithstanding any of


                                      I-8
<PAGE>   168

the foregoing, this Agreement shall not in any way be deemed to obligate Secured
Party, any Lender or any purchaser at a foreclosure sale under this Agreement to
assume any of any Grantor's obligations, duties, expenses or liabilities under
any LLC Agreement or Partnership Agreement (including any Grantor's obligations
as a general partner for the debts and obligations of a Partnership) and to
manage the business and affairs of any Partnership or any of such Grantor's
obligations for the debts and obligations of an LLC, or under any and all other
agreements now existing or hereafter drafted or executed (collectively, the
"Grantor Obligations") unless Secured Party, any Lender or any such purchaser
otherwise expressly agrees in writing to assume any or all of said Grantor
Obligations. In the event of foreclosure by Secured Party, each Grantor shall
remain bound and obligated to perform its Grantor Obligations arising during or
otherwise related to its ownership of the Collateral, and neither Secured Party
nor any Lender shall be deemed to have assumed any of such Grantor Obligations
except as provided in the preceding sentence. Without limiting the generality of
the foregoing, neither the grant of the security interest in the Collateral in
favor of Secured Party as provided herein nor the exercise by Secured Party of
any of its rights hereunder nor any action by the Secured Party in connection
with a foreclosure on the Collateral shall be deemed to constitute Secured Party
or any Lender a partner of any Partnership or a member of any LLC; provided, in
the event Secured Party or any purchaser of Collateral at a foreclosure sale
elects to become a substituted general partner of any Partnership or manager of
any LLC in place of any Grantor, Secured Party or such purchaser, as the case
may, shall adopt in writing the applicable Partnership Agreement or LLC
Agreement, as the case may be, and agree to be bound by the terms and provisions
thereof.

SECTION 4. FURTHER ASSURANCES; ADDITIONAL GRANTORS

         4.1. Generally. Each Grantor agrees that from time to time, at the
expense of Grantor, each Grantor will promptly execute and deliver all further
instruments and documents, and take all further action, that may be necessary or
desirable, or that Secured Party may reasonably request, in order to perfect and
protect any security interest granted or purported to be granted hereby or to
enable Secured Party to exercise and enforce its rights and remedies hereunder
with respect to any Collateral. Subject to the provisions of the Credit
Agreement, without limiting the generality of the foregoing, each Grantor will

Secured Party may reasonably request, in order to perfect and preserve the

statements, and amendments thereto, relative to all or any part of the
Collateral without the signature of Grantor. Each Grantor agrees that a carbon,
photographic or other reproduction of this Agreement or of a financing statement
signed by Grantor shall be sufficient as a financing statement and may be filed
as a financing statement in any and all jurisdictions. Each Grantor will furnish
to Secured Party from time to time statements and schedules further identifying
and describing the Collateral and such other reports in connection with the
Collateral as Secured Party may reasonably request, all in reasonable detail.

         4.2. Investment Property.

         (a) Each Grantor agrees that it will, upon obtaining any additional
shares of stock or other securities required to be pledged hereunder, promptly
(and in any event within ten Business Days) deliver to Secured Party a Pledge
Supplement, duly executed by Grantor, in substantially the form of Exhibit A (a
"Pledge Supplement"), in respect of the additional Pledged Stock to be pledged
pursuant to this Agreement. Each Grantor hereby authorizes Secured Party to
attach each Pledge Supplement to this Agreement and agrees that all Pledged
Stock of Grantor listed on any Pledge Supplement shall for all purposes
hereunder be considered Collateral of Grantor; provided, the failure of any
Grantor to execute a Pledge Supplement with respect to any additional Pledged
Stock pledged pursuant to this Agreement shall not impair the security interest
of Secured Party therein or otherwise adversely affect the rights and remedies
of Secured Party hereunder with respect thereto.

         (b) At the request of Secured Party, each Grantor shall cause, at
Grantor's expense, each Person which is an issuer of an uncertificated security
included in the Collateral to execute and deliver all instruments and documents,
and take all further action Secured Party may reasonably request, in order to
perfect and protect any security interest granted or purported to be granted in
such uncertificated securities, to establish "control" (as such term is defined
in the


                                      I-11
<PAGE>   171

UCC) by Secured Party over such Collateral or to enable Secured Party to
exercise and enforce its rights and remedies hereunder with respect to such
Collateral, including, and as applicable, (i) register the security interest
granted hereby upon the books of such Person in accordance with Article 8 of the
UCC, and (ii) deliver to Secured Party an Acknowledgment of Pledge, duly
executed by such the issuer of the applicable uncertificated security, in

         4.3. Intellectual Property Collateral. On the last Business Day of each
Fiscal Quarter, each Subsidiary Grantor shall notify Administrative Agent of all
rights obtained by such Grantor to any new material Intellectual Property
Collateral during such Fiscal Quarter and also whether such Grantor became
entitled during such Fiscal Quarter to the benefit of (a) any patent application
or patent or any reissue, division, continuation, renewal, extension or
continuation-in-part of any Patent or any improvement of any Patent; or (b) any
Copyright Registration, application for Registration or renewals or extension of
any Copyright, and in any such case, upon the giving of such notice, the
provisions of this Agreement shall apply thereto. On the last Business Day of
each Fiscal Quarter, each Grantor shall notify Secured Party in writing of any
of the foregoing rights acquired by Grantor during such Fiscal Quarter and of
(i) any Trademark Registrations issued or applications for Trademark
Registration or applications for Patents made, and (ii) any Copyright
Registrations issued or applications for Copyright Registration made, in any
such case, during such Fiscal Quarter. On the last Business Day of each Fiscal
Quarter, with respect to the filing of an application, during such Fiscal
Quarter, for any (1) Trademark Registration; (2) Patent; and (3) Copyright
Registration, each Subsidiary Grantor shall execute and deliver to Secured Party
and record in all places where this Agreement is recorded a Pledge Supplement,
pursuant to which such Grantor shall grant to Secured Party a security interest
to the extent of its interest in such Intellectual Property Collateral;
provided, if, in the reasonable judgment of such Grantor, after due inquiry,
granting such interest would result in the grant of a Trademark Registration or
Copyright Registration in the name of Secured Party, in which event such Grantor
shall give written notice to Secured Party as soon as reasonably practicable and
the filing shall instead be undertaken as soon as practicable but in no case
later than immediately following the grant of the applicable Trademark
Registration or Copyright Registration, as the case may be. In addition to the
foregoing, each Grantor hereby authorizes Secured Party to modify this Agreement
without obtaining Grantor's approval of or signature to such modification by
amending Schedule 1(c), as applicable, to include reference to any right, title
or interest in any existing Intellectual Property Collateral or any Intellectual
Property Collateral acquired or developed by any Subsidiary Grantor after the
execution hereof or to delete any reference to any right, title or interest in
any Intellectual Property Collateral in which such Grantor no longer has or
claims any right, title or interest.

         4.4. Accounts. At the reasonable request of Secured party, each
Subsidiary Grantor shall (a) mark conspicuously each item of chattel paper
included in the Accounts, each Related Contract and, at the reasonable request
of Secured Party, each of its records pertaining to the Collateral, with a
legend, in form and substance reasonably satisfactory to Secured Party,
indicating that such Collateral is subject to the security interest granted
hereby, and (b) at the


                                      I-12
<PAGE>   172

reasonable request of Secured Party, deliver and pledge to Secured Party
hereunder all promissory notes and other instruments (excluding checks) and all
original counterparts of chattel paper constituting Collateral, duly endorsed
and accompanied by duly executed instruments of transfer or assignment, all in
form and substance reasonably satisfactory to Secured Party.

         4.5. Equipment. Each Subsidiary Grantor shall (a) promptly after the
acquisition by such Grantor of any item of Equipment which is covered by a
certificate of title under a statute of any jurisdiction under the law of which
indication of a security interest on such certificate is required as a condition
of perfection thereof, upon the reasonable request of Secured Party, execute and
file with the registrar of motor vehicles or other appropriate authority in such
jurisdiction an application or other document requesting the notation or other
indication of the security interest created hereunder on such certificate of
title, and (b) upon the reasonable request of Secured Party, deliver to Secured
Party copies of all such applications or other documents filed during such
calendar quarter and copies of all such certificates of title issued during such
calendar quarter indicating the security interest created hereunder in the items
of Equipment covered thereby.

         4.6. Additional Grantors. From time to time subsequent to the date
hereof, additional Persons may become parties hereto as additional Grantors
(each, an "Additional Grantor"), by executing a Pledge Supplement. Upon delivery
of any such Counterpart Agreement to Secured Party, notice of which is hereby
waived by Grantors, each Additional Grantor shall be a Grantor and shall be as
fully a party hereto as if Additional Grantor were an original signatory hereto.
Each Grantor expressly agrees that its obligations arising hereunder shall not
be affected or diminished by the addition or release of any other Grantor
hereunder, nor by any election of Administrative Agent not to cause any
Subsidiary of Company to become an Additional Grantor hereunder. This Agreement
shall be fully effective as to any Grantor that is or becomes a party hereto
regardless of whether any other Person becomes or fails to become or ceases to
be a Grantor hereunder.

SECTION 5. COVENANTS OF GRANTORS

         5.1. Generally. Each Grantor shall (a) except for the security interest
created by this Agreement, not create or suffer to exist any Lien upon or with
respect to any of the Collateral, except Permitted Liens; (b) not use or permit
any Collateral to be used unlawfully or in violation of any provision of this
Agreement or any applicable statute, regulation or ordinance or any policy of
insurance covering the Collateral; (c) notify Secured Party of any change in
Grantor's name, identity or corporate structure within 15 days of such change
and take such action as Secured Party may reasonably request in order to protect
or perfect any security interest granted or purported to be granted hereby or to
enable Secured Party to exercise and enforce its rights and remedies hereunder;
(d) diligently keep reasonable records respecting the Intellectual Property
Collateral and at all times keep at least one complete set of its records
concerning such Collateral at its chief executive office or principal place of
business; (e) if Secured Party gives value to enable Grantor to acquire rights
in or the use of any Collateral, use such value for such


                                      I-13
<PAGE>   173

purposes; (f) pay promptly when due all property and other taxes, assessments
and governmental charges or levies imposed upon, and all claims (including
claims for labor, materials and supplies) against, the Collateral, except to the
extent the validity thereof is being contested in good faith; provided, Grantor
shall in any event pay such taxes, assessments, charges, levies or claims not
later than five days prior to the date of any proposed sale under any judgement,
writ or warrant of attachment entered or filed against Grantor or any of the
Collateral as a result of the failure to make such payment; and (g) upon any
officer of such Grantor obtaining knowledge thereof, promptly notify Secured
Party in writing of any event that may materially and adversely affect the value
of the Collateral or any material portion thereof, the ability of Grantor or
Secured Party to dispose of the Collateral or any material portion thereof, or
the rights and remedies of Secured Party in relation thereto, including, without
limitation, the levy of any legal process against the Collateral or any material
portion thereof. No Grantor shall sell, transfer or assign (by operation of law
or otherwise) any Collateral except as permitted by Section 6 of the Credit
Agreement (a "Permitted Sale"). So long as (i) no Event of Default shall have
occurred and is then continuing or would occur after giving effect to a
Permitted Sale, and (ii) the Net Asset Sale Proceeds with respect to such
Permitted Sale are delivered to Secured Party contemporaneously with such
Permitted Sale, Secured Party shall release the Lien hereof encumbering the
Collateral that is the subject of such Permitted Sale. Secured Party shall
execute each and every appropriate filing statement and/or recording document
reasonably requested by and, at the expense of, any Grantor in connection with
the foregoing. Any reasonable expense or cost incurred by Secured Party in
connection with any such release shall be for the account of the applicable
Grantor.

         5.2. Investment Property.

         (a)  Delivery.

                  (i) All certificates or instruments representing or evidencing
         the Investment Property shall be delivered to and held by or on behalf
         of Secured Party pursuant hereto and shall be in suitable form for
         transfer by delivery or, as applicable, shall be accompanied by
         Grantor's endorsement, where necessary, or duly executed instruments
         of transfer or assignment in blank, all in form and substance
         satisfactory to Secured Party. Upon the occurrence and during the
         continuation of an Event of Default, Secured Party shall have the
         right, without notice to any Grantor, to transfer to or to register in

         Grantor shall be entitled to exercise any and all voting and other
         consensual rights pertaining to the Investment Property or any part
         thereof for any purpose not inconsistent with the terms of this
         Agreement or the Credit Agreement; provided, no Grantor shall exercise

         shall give Secured Party at least two Business Days' prior written
         notice of the manner in which it intends to exercise, or the reasons

         incidental matters at any such meeting, nor (B) Grantor's consent to or
         approval of any action otherwise permitted under this Agreement and the
         Credit Agreement shall be deemed inconsistent with the terms of this
         Agreement or the Credit Agreement within the meaning of this Section,
         and no notice of any such voting or consent need be given to Secured
         Party; (2) Grantor shall be entitled to receive and retain, and to

                                      I-16
<PAGE>   176

         Grantor and be forthwith delivered to Secured Party as Investment
         Property in the same form as so received (with all necessary
         endorsements); and (3) Secured Party shall promptly execute and deliver
         (or cause to be executed and delivered) to Grantor all such proxies,
         dividend payment orders and other instruments as Grantor may from time
         to time reasonably request for the purpose of enabling Grantor to
         exercise the voting and other consensual rights when and to the extent
         which it is entitled to exercise pursuant to clause (i) above and to
         receive the dividends, principal or interest payments which it is
         authorized to receive and retain pursuant to clause (2) above.

                  (ii) Upon the occurrence and during the continuation of an
         Event of Default, (1) upon written notice from Secured Party to any
         Grantor, all rights of Grantor to exercise the voting and other
         consensual rights which it would otherwise be entitled to exercise
         pursuant hereto shall cease, and all such rights shall thereupon become
         vested in Secured Party who shall thereupon have the sole right to
         exercise such voting and other consensual rights; (2) all rights of
         Grantor to receive the dividends and interest payments which it would

         Party who shall thereupon have the sole right to receive and hold as
         Investment Property such dividends and interest payments; and (3) all
         payments which are received by Grantor contrary to the provisions of
         clause (2) above shall be received in trust for the benefit of Secured
         Party, shall be segregated from other funds of Grantor and shall

         connection with the Partnership Agreements and/or the LLC Agreements,
         including but not limited to the profits, dividends, and other
         distributions which it would otherwise be authorized to receive and
         retain pursuant hereto, shall cease, and all such rights shall
         thereupon become vested in Secured Party who shall thereupon have the
         sole right to receive and hold such payments as collateral.

                  (iii) IN ORDER TO PERMIT SECURED PARTY TO EXERCISE THE VOTING
         AND OTHER CONSENSUAL RIGHTS WHICH IT MAY BE EN TITLED TO EXERCISE
         PURSUANT HERETO AND TO RECEIVE ALL DIVIDENDS AND OTHER DISTRIBUTIONS
         WHICH IT MAY BE ENTITLED TO RECEIVE HEREUNDER, (1) GRANTOR SHALL
         PROMPTLY EXECUTE AND DELIVER (OR CAUSE TO BE EXECUTED AND DELIVERED) TO
         SECURED PARTY ALL SUCH PROXIES, DIVIDEND PAYMENT ORDERS AND OTHER
         INSTRUMENTS AS SECURED PARTY MAY FROM TIME TO TIME REASONABLY REQUEST,
         AND (2) WITHOUT LIMITING THE EFFECT OF CLAUSE (1) ABOVE, GRANTOR HEREBY
         GRANTS TO SECURED PARTY AN IRREVOCABLE PROXY TO VOTE THE PLEDGED


                                      I-17

         STOCK AND TO EXERCISE ALL OTHER RIGHTS, POWERS, PRIVILEGES AND REMEDIES
         TO WHICH A HOLDER OF THE PLEDGED STOCK WOULD BE ENTITLED (INCLUDING
         GIVING OR WITHHOLDING WRITTEN CONSENTS OF SHAREHOLDERS, CALLING SPECIAL
         MEETINGS OF SHAREHOLDERS AND VOTING AT SUCH MEETINGS), WHICH PROXY
         SHALL BE EFFECTIVE, AUTOMATICALLY AND WITHOUT THE NECESSITY OF ANY
         ACTION (INCLUDING ANY TRANSFER OF ANY PLEDGED STOCK ON THE RECORD BOOKS
         OF THE ISSUER THEREOF) BY ANY OTHER PER SON (INCLUDING THE ISSUER OF
         THE PLEDGED STOCK OR ANY OFFICER OR AGENT THEREOF), UPON THE
         OCCURRENCE AND DURING THE CONTINUATION OF AN EVENT OF DEFAULT, AND
         WHICH PROXY SHALL ONLY TERMINATE UPON THE PAYMENT IN FULL OF THE
         SECURED OBLIGATIONS (OTHER THAN INCHOATE INDEMNIFICATION OBLIGATIONS
         WITH RESPECT TO CLAIMS, LOSSES OR LIABILITIES WHICH HAVE NOT YET ARISEN
         AND ARE NOT YET DUE AND PAY ABLE).

         5.3. Intellectual Property Collateral.

         (a) Covenants. Each Subsidiary Grantor shall (i) hereafter use
commercially reasonable efforts so as not to permit the inclusion in any
contract to which it hereafter becomes a party of any provision that could or
might in any way materially impair or prevent the creation of a security
interest in, or the assignment of, Grantor's rights and interests in any
property included within the definitions of any Intellectual Property Collateral
acquired under such contracts; (ii) take all steps reasonably necessary to
protect the secrecy of all trade secrets relating to the products and services
sold or delivered under or in connection with the Intellectual Property
Collateral, including, without limitation, entering into confidentiality
agreements with employees and labeling and restricting access to secret
information and documents; (iii) use proper statutory notice in connection with
its use of any of the Intellectual Property Collateral; (iv) use consistent
standards of high quality (which may be consistent with Grantor's past
practices) in the manufacture, sale and delivery of products and services sold
or delivered under or in connection with the Intellectual Property Collateral;
and (v) furnish to Secured Party on the last Business Day of each Fiscal Quarter
statements and schedules further identifying and describing any Intellectual
Property Collateral and such other reports in connection with such Collateral as
Secured Party may reasonably request, all in reasonable detail.

         (b) Collections. Except as otherwise provided in this Section 5.3, each
Grantor shall continue to collect, at its own expense, all amounts due or to
become due to Grantor in respect of the Intellectual Property Collateral or any
portion thereof. In connection with such collections, each Grantor may take
(and, at Secured Party's reasonable direction, shall take) such action as
Grantor or Secured Party may deem reasonably necessary or advisable to enforce
collection of such amounts; provided, Secured Party shall have the right at any
time, upon the occurrence and during the continuation of an Event of Default
and upon written notice to Grantor of its intention


                                      I-18
<PAGE>   178

to do so, to notify the obligors with respect to any such amounts of the
existence of the security interest created hereby and to direct such obligors to
make payment of all such amounts directly to Secured Party, and, upon such
notification and at the expense of Grantor, to enforce collection of any such
amounts and to adjust, settle or compromise the amount or payment thereof, in
the same manner and to the same extent as Grantor might have done. After receipt
by any Grantor of the notice from Secured Party referred to in the proviso to
the preceding sentence and during the continuation of any Event of Default, (i)
all amounts and proceeds (including checks and other instruments) received by
Grantor in respect of amounts due to Grantor in respect of the Collateral or any
portion thereof shall be received in trust for the benefit of Secured Party
hereunder, shall be segregated from other funds of Grantor and shall be
forthwith paid over or delivered to Secured Party in the same form as so
received (with any necessary endorsement) to be held as cash Collateral and
applied as provided by Section 7.5, and (ii) Grantor shall not adjust, settle or
compromise the amount or payment of any such amount or release wholly or partly
any obligor with respect thereto or allow any credit or discount thereon.

         (c) Applications and Registrations. Each Subsidiary Grantor shall have
the duty diligently, through counsel reasonably acceptable to Secured Party, to
prosecute, file and/or make, unless and until such Grantor, in its commercially
reasonable judgment, decides otherwise, (i) any application relating to any of
the Intellectual Property Collateral owned, held or used by such Grantor and
identified on Schedule 1(c), that is pending as of the date of this Agreement,
(ii) any Registration on any existing or future unregistered but copyrightable
works (except for works of nominal commercial value or with respect to which
such Grantor has determined in the exercise of its commercially reasonable
judgment that it shall not seek registration), (iii) application on any existing
patent or future patentable but unpatented invention comprising Intellectual
Property Collateral, and (iv) any Trademark opposition and cancellation
proceedings, renew Trademark Registrations and Copyright Registrations and do
any and all acts which are necessary or desirable, as determined in such
Grantor's commercially reasonable judgment, to preserve and maintain all rights
in all Intellectual Property Collateral. Any expenses incurred in connection
therewith shall be borne solely by such Grantor. Subject to the foregoing,
Subsidiary Grantor shall give Secured Party prior written notice of any
abandonment of any material Intellectual Property Collateral or any right to
file a patent application or any pending patent application or any Patent.

         (d) Litigation. Except as provided herein, each Grantor shall have the
right to commence and prosecute in its own name, as real party in interest, for
its own benefit and at its own expense, such suits, proceedings or other actions
for infringement, unfair competition, dilution, misappropriation or other
damage, or reexamination or reissue proceedings as are in its commercially
reasonable judgment necessary to protect the Intellectual Property Collateral.
Secured Party shall provide, at Grantor's expense, all reasonable and necessary
cooperation in connection with any such suit, proceeding or action including,
without limitation, joining as a necessary party. Each Grantor shall promptly,
following its becoming aware thereof, notify Secured Party of the institution
of, or of any adverse determination in, any proceeding (whether in the United
States Patent and Trademark Office, the United States Copyright Office or any


                                      I-19
<PAGE>   179

federal, state, local or foreign court) or regarding Subsidiary Grantor's
ownership, right to use, or interest in any material Intellectual Property
Collateral. Grantor shall provide to Secured Party any information with respect
thereto reasonably requested by Secured Party.

         (e) Certain Rights of Secured Party. In addition to, and not by way of
limitation of, the granting of a security interest in the Collateral pursuant
hereto, each Grantor, effective upon the occurrence and during the continuation
of an Event of Default and upon written notice from Secured Party, shall grant,
sell, convey, transfer, assign and set over to Secured Party, for its benefit
and the ratable benefit of Lenders, all of Subsidiary Grantor's right, title and
interest in and to the Intellectual Property Collateral to the extent necessary
to enable Secured Party to use, possess and realize on the Collateral and to
enable any successor or assign to enjoy the benefits of the Collateral. This
right and license shall inure to the benefit of all successors, assigns and
transferees of Secured Party and its successors, assigns and transferees,
whether by voluntary conveyance, operation of law, assignment, transfer,
foreclosure, deed in lieu of foreclosure or otherwise. Such right and license
shall be granted free of charge, without requirement that any monetary payment
whatsoever be made to such Grantor. Subject to the provisions of the Credit
Agreement, in addition, each Grantor hereby grants to Secured Party and its
employees, representatives and agents the right to visit Grantor's and any of
its Affiliate's or subcontractor's plants, facilities and other places of
business that are utilized in connection with the manufacture, production,
inspection, storage or sale of products and services sold or delivered under any
of the Intellectual Property Collateral (or which were so utilized during the
prior six month period), and to inspect the quality control and all other
records relating thereto upon reasonable advance written notice to Grantor and
at reasonable dates and times and as often as may be reasonably requested. If
and to the extent that any Subsidiary Grantor is permitted to license the
Intellectual Property Collateral, Secured Party shall promptly enter into a
non-disturbance agreement or other similar arrangement, at Grantor's request and
expense, with Grantor and any licensee of any Intellectual Property Collateral
permitted hereunder in form and substance reasonably satisfactory to Secured
Party pursuant to which (i) Secured Party shall agree not to disturb or
interfere with such licensee's rights under its license agreement with Grantor
so long as such licensee is not in default thereunder, and (ii) such licensee
shall acknowledge and agree that the Intellectual Property Collateral licensed
to it is subject to the security interest created in favor of Secured Party and
the other terms of this Agreement.

         5.4. Equipment and Inventory. Each Subsidiary Grantor shall, with
respect to Equipment and Inventory included in the Collateral:

         (a) keep the Equipment and Inventory in the jurisdictions specified on
Schedule 5.4 or upon 30 days' written notice to Secured Party, in such other
jurisdictions where all action that Secured Party may reasonably request, in
order to perfect and protect any security interest granted or purported to be
granted hereby, or to enable Secured Party to exercise and enforce its rights
and remedies hereunder, with respect to such Equipment and Inventory shall have
been taken;


                                      I-20
<PAGE>   180

         (b) keep correct and accurate records of the Inventory, itemizing and
describing the kind, type and quantity of Inventory, such Grantor's cost
therefor and (where applicable) the current list prices for the Inventory; and

         (c) if any Inventory is in possession or control of any of such
Grantor's agents or processors, upon the occurrence and during the continuance
of an Event of Default, instruct such agent or processor to hold all such
Inventory for the account of Secured Party and subject to the instructions of
Secured Party.

         5.5. Accounts and Related Contracts. Each Grantor shall:

         (a) keep its chief place of business and chief executive office and the
office where it keeps its records concerning the Accounts and Related Contracts,
and all originals of all chattel paper that evidence Accounts, at the location
therefor specified on Schedule 5.5 or, upon 30 days' written notice to Secured
Party following any change in location, at such other location in a jurisdiction
where all action that Secured Party may request, in order to perfect and protect
any security interest granted or purported to be granted hereby, or to enable
Secured Party to exercise and enforce its rights and remedies hereunder, with
respect to such Accounts and Related Contracts shall have been taken. Promptly
upon the reasonable request of Secured Party, such Grantor shall deliver to
Secured Party complete and correct copies of each Related Contract;

         (b) maintain (i) complete records of all Accounts, including records of
all payments received, credits granted and merchandise returned, and (ii) all
documentation relating thereto in accordance with prudent business practices;

         (c) except as otherwise provided in this subsection (c), continue to
collect, at its own expense, all amounts due or to become due to such Grantor
under the Accounts and Related Con tracts, and in connection with such
collections, such Grantor shall take such action as such Grantor or Secured
Party may deem necessary or advisable to enforce collection of amounts due or to
become due under the Accounts and Related Contracts; provided, Secured Party
shall have the right at any time, upon the occurrence and during the
continuation of an Event of Default and upon written notice to such Grantor of
its intention to do so, to notify the account debtors or obligors under any
Accounts and Related Contracts of the assignment of such Accounts and Related
Contracts to Secured Party and to direct such account debtors or obligors to
make payment of all amounts due or to become due to such Grantor thereunder
directly to Secured Party, to notify each Person maintaining a lockbox or
similar arrangement to which account debtors or obligors under any Accounts and
Related Contracts have been directed to make payment to remit all amounts
representing collections on checks and other payment items from time to time
sent to or deposited in such lockbox or other arrangement directly to Secured
Party and, upon such notification and at the expense of such Grantor, to enforce
collection of any such Accounts and Related Contracts and to adjust, settle or
compromise the amount or payment thereof, in the same manner and to the same
extent as such Grantor might have done. After receipt by any Grantor of the
notice from Secured Party referred to in the proviso to the preced-


                                      I-21
<PAGE>   181

ing sentence, (i) any payments of Accounts and Related Contracts, received by
such Grantor shall be forthwith (and in any event within two Business Days)
deposited by such Grantor in the exact form received, duly indorsed by such
Grantor to the Secured Party if required, in an account (the "Collateral
Account") maintained under the sole dominion and control of the Secured Party,
subject to withdrawal by the Secured Party for the account of the Secured
Parties as provided in Section 7.5, (ii) until so turned over in accordance with
the preceding subsection (i), all amounts and proceeds (including checks and
other instruments) received by such Grantor in respect of the Accounts and the
Related Contracts shall be received in trust for the benefit of Secured Party
hereunder and shall be segregated from other funds of such Grantor and (iii)
such Grantor shall not adjust, settle or compromise the amount or payment of any
Account and Related Contracts, or release wholly or partly any account debtor or
obligor thereof, or allow any credit or discount thereon.

SECTION 6. SECURED PARTY APPOINTED ATTORNEY-IN-FACT

         Each Grantor hereby irrevocably appoints Secured Party as Grantor's
attorney-in-fact, with full authority in the place and stead of Grantor and in
the name of Grantor, Secured Party or otherwise, from time to time in Secured
Party's discretion to take any action and to execute any instrument that Secured
Party may deem reasonably necessary or advisable to accomplish the purposes of
this Agreement, including (a) to obtain and adjust insurance required to be
maintained by Grantor or paid to Secured Party pursuant to the Credit Agreement;

permitted under this Agreement or the Credit Agreement) levied or placed upon or
threatened against the Collateral, the legality or validity thereof and the
amounts necessary to discharge the same to be determined by Secured Party in its
sole discretion, any such payments made by Secured Party to become obligations
of Grantor to Secured Party, due and payable immediately without demand; and (f)
upon the occurrence and during the continuation of an Event of Default,
generally to sell, transfer, pledge, make any agreement with respect to or
otherwise deal with any of the Collateral as fully and completely as though
Secured Party were the absolute owner thereof for all purposes, and to do, at
Secured Party's option and Grantor's expense, at any time or from time to time,
all acts and things that Secured Party deems reasonably necessary to protect,
preserve or realize upon the Collateral and Secured Party's security interest
therein in order to effect the intent of this Agreement, all as fully and
effectively as Grantor might do.

SECTION 7. REMEDIES

         7.1. Generally. If any Event of Default shall have occurred and be
continuing, Secured Party may exercise in respect of the Collateral, in addition
to all other rights and remedies provided for herein or otherwise available to

or not the Code applies to the affected Collateral), and also may (a) require
any Grantor to, and each Grantor hereby agrees that it will at its expense and
upon request of Secured Party forthwith, assemble all or part of the Collateral
as directed by Secured Party and make it available to Secured Party at a place
to be designated by Secured Party that is reasonably convenient to both parties;
(b) enter onto the property where any Collateral is located and take possession

other terms as Secured Party may deem commercially reasonable; and (e) exercise
dominion and control over, and refuse to permit further withdrawals (whether of
money, securities, instruments or other property) from any deposit account

permitted by applicable law, Secured Party or any Lender or Lender Counterparty
may be the purchaser of any or all of the Collateral at any such sale and
Secured Party, as agent for and representative of Lenders and Lender
Counterparties (but not any Lender or Lenders or Lender Counterparties in its or
their respective individual capacities unless Requisite Lenders shall otherwise
agree in writing), shall be entitled, for the purpose of bidding and making
settlement or payment of the purchase price for all or any portion of the
Collateral sold at any such public sale, to use and apply any of the Secured
Obligations as a credit on account of the purchase price for any Collateral
payable by Secured Party at such sale. Each purchaser at any such sale shall
hold the property sold absolutely free from any claim or right on the part of
any Grantor, and each Grantor hereby waives (to the extent permitted by
applicable law) all rights of redemption, stay and/or appraisal which it now has
or may at any time in the future have under any rule of law or statute now
existing or hereafter enacted. To the extent permitted by applicable law, each
Grantor agrees that, to the extent notice of sale shall be required by law, at
least ten days' notice to Grantor of the time and place of any public sale or
the time after which any private sale is to be made shall constitute reasonable
notification. Secured Party shall not be obligated to make any sale of
Collateral regardless of notice of sale having been given. Secured Party may
adjourn any public or private sale from time to time by announcement at the time
and place fixed therefor, and such sale may, without further notice, be made at
the time and place to which it was so adjourned. Each Grantor hereby waives any
claims against Secured Party arising by reason of the fact that the price at
which any Collateral may have been sold at such a private sale was less than the
price which might have been obtained at a public sale, even if Secured Party
accepts the first offer received and does not offer such Collateral to more than
one offeree. If the proceeds of any sale or other disposition of the


                                      I-23
<PAGE>   183

Collateral are insufficient to pay all the Secured Obligations, Grantors shall
be liable for the deficiency and the fees of any attorneys employed by Secured
Party to collect such deficiency. Each Grantor further agrees that a breach of
any of the covenants contained in this Section will cause irreparable injury to
Secured Party, that Secured Party has no adequate remedy at law in respect of
such breach and, as a consequence, that each and every covenant contained in
this Section shall be specifically enforceable against Grantor, and Grantor
hereby waives and agrees not to assert any defenses against an action for
specific performance of such covenants except for a defense that no default has
occurred giving rise to the Secured Obligations (other than inchoate
indemnification obligations with respect to claims, losses or liabilities which
have not yet arisen and are not yet due and payable) becoming due and payable
prior to their stated maturities. Nothing in this Section shall in any way alter
the rights of Secured Party hereunder.

         7.2. Investment Property. Each Grantor recognizes that, by reason of
certain prohibitions contained in the Securities Act of 1933, as amended, and
applicable state securities laws, Secured Party may be compelled, with respect
to any sale of all or any part of the Investment Property conducted without
prior registration or qualification of such Investment Property under the
Securities Act and/or such state securities laws, to limit purchasers to those
who will agree, among other things, to acquire the Investment Property for their
own account, for investment and not with a view to the distribution or resale
thereof. Each Grantor acknowledges that any such private sales may be at prices
and on terms less favorable than those obtainable through a public sale without
such restrictions (including a public offering made pursuant to a registration
statement under the Securities Act) and, notwithstanding such circumstances each
Grantor agrees that any such private sale shall be deemed to have been made in a
commercially reasonable manner and that Secured Party shall have no obligation
to engage in public sales and no obligation to delay the sale of any Investment
Property for the period of time necessary to permit the issuer thereof to
register it for a form of public sale requiring registration under the
Securities Act or under applicable state securities laws, even if such issuer
would, or should, agree to so register it. If Secured Party determines to
exercise its right to sell any or all of the Investment Property, upon written
request, each Grantor shall and shall cause each issuer of any Pledged Stock to
be sold hereunder, each Partnership and each LLC from time to time to furnish to
Secured Party all such information as Secured Party may request in order to
determine the number and nature of interest, shares or other instruments
included in the Investment Property which may be sold by Secured Party in exempt
transactions under the Securities Act and the rules and regulations of the
Securities and Exchange Commission thereunder, as the same are from time to time
in effect.

         7.3. Intellectual Property Collateral.

         (a) Anything contained herein to the contrary notwithstanding, upon the
occurrence and during the continuation of an Event of Default, (i) Secured Party
shall have the right (but not the obligation) to bring suit, in the name of any
Grantor, Secured Party or otherwise, to enforce any Intellectual Property
Collateral, in which event such Grantor shall, at the request of Secured Party,
do any and all lawful acts and execute any and all documents required by Secured
Party in


                                      I-24
<PAGE>   184

aid of such enforcement and Grantor shall promptly, upon demand, reimburse and
indemnify Secured Party as provided in the Credit Agreement in connection with
the exercise of its rights under this Section, and, to the extent that Secured
Party shall elect not to bring suit to enforce any Intellectual Property
Collateral as provided in this Section, each Grantor agrees to use all
reasonable measures, whether by action, suit, proceeding or otherwise, to
prevent the infringement of any of the Intellectual Property Collateral by
others and for that purpose agrees to diligently maintain any action, suit or
proceeding against any Person so infringing necessary to prevent such
infringement; (ii) upon written demand from Secured Party, each Grantor shall
execute and deliver to Secured Party an assignment or assignments of the
Intellectual Property Collateral and such other documents as are necessary or
appropriate to carry out the intent and purposes of this Agreement; (iii) each
Grantor agrees that such an assignment and/or recording shall be applied to
reduce the Secured Obligations outstanding only to the extent that Secured Party
(or any Lender) receives cash proceeds in respect of the sale of, or other
realization upon, the Intellectual Property Collateral; and (iv) within five
Business Days after written notice from Secured Party, Grantor shall make
available to Secured Party, to the extent within Grantor's power and authority,
such personnel in Grantor's employ on the date of such Event of Default as
Secured Party may reasonably designate, by name, title or job responsibility, to
permit such Grantor to continue, directly or indirectly, to produce, advertise
and sell the products and services sold or delivered by such Grantor under or in
connection with the Trademarks, Trademark Registrations and Trademark Rights,
such persons to be available to perform their prior functions on Secured Party's
behalf and to be compensated by Secured Party at Grantor's expense on a per
diem, pro-rata basis consistent with the salary and benefit structure applicable
to each as of the date of such Event of Default.

         (b) If (i) an Event of Default shall have occurred and, by reason of
cure, waiver, modification, amendment or otherwise, no longer be continuing,
(ii) no other Event of Default shall have occurred and be continuing, (iii) an
assignment to Secured Party of any rights, title and interests in and to the
Intellectual Property Collateral shall have been previously made and shall have
become absolute and effective, and (iv) the Secured Obligations shall not have
become immediately due and payable, upon the written request of Grantor, Secured
Party shall promptly execute and deliver to Grantor such assignments as may be
necessary to reassign to Grantor any such rights, title and interests as may
have been assigned to Secured Party as aforesaid, subject to any disposition
thereof that may have been made by Secured Party; provided, after giving effect
to such reassignment, Secured Party's security interest granted pursuant hereto,
as well as all other rights and remedies of Secured Party granted hereunder,
shall continue to be in full force and effect; and provided further, the rights,
title and interests so reassigned shall be free and clear of all Liens other
than Liens (if any) encumbering such rights, title and interest at the time of
their assignment to Secured Party and Permitted Liens.

         7.4. Accounts. In addition to the rights of the Secured Party and the
Secured Parties specified in Section 8 with respect to payments of Accounts, if
an Event of Default shall occur and be continuing, upon request of the Secured
Party, all proceeds received by any Grantor consisting of cash, checks and other
near-cash items shall be held by such Grantor in trust for the


                                      I-25
<PAGE>   185

Secured Party and the Secured Parties, segregated from other funds of such
Grantor, and shall, forthwith upon receipt by such Grantor, be turned over to
the Secured Party in the exact form received by such Grantor (duly indorsed by
such Grantor to the Secured Party, if required) and held by the Secured Party in
the Collateral Account. All proceeds while held by the Secured Party in the
Collateral Account (or by the Borrower in trust for the Secured Party and the
Secured Parties) shall continue to be held as collateral security for all the
Obligations and shall not constitute payment thereof until applied as provided
in Section 7.5.

         7.5. Application of Proceeds. Except as expressly provided elsewhere in
this Agreement, all proceeds received by Secured Party in respect of any sale
of, collection from, or other realization upon all or any part of the Collateral
shall be applied as provided in Section 2.13 of the Credit Agreement.

SECTION 8. SECURED PARTY AS AGENT

         Secured Party has been appointed to act as Secured Party hereunder by
Lenders and, by their acceptance of the benefits hereof, Lender Counterparties.
Secured Party shall be obligated, and shall have the right hereunder, to make
demands, to give notices, to exercise or refrain from exercising any rights, and
to take or refrain from taking any action (including the release or substitution
of Collateral), solely in accordance with this Agreement and the Credit
Agreement; provided, Secured Party shall exercise, or refrain from exercising,
any remedies provided for herein in accordance with the instructions of (a)
Requisite Lenders or (b) after payment in full in cash of all Obligations under
the Credit Agreement and the other Credit Documents, the holders of a majority
of the aggregate notional amount (or, with respect to any Hedge Agreement that
has been terminated in accordance with its terms, the amount then due and
payable (exclusive of expenses and similar payments but including any early
termination payments then due) under such Hedge Agreement) under all Hedge
Agreements (Requisite Lenders or, if applicable, such holders being referred to
herein as "Requisite Obligees"). In furtherance of the foregoing provisions of
this Section, each Lender Counterparty, by its acceptance of the benefits
hereof, agrees that it shall have no right individually to realize upon any of
the Collateral hereunder, it being understood and agreed by such Lender
Counterparty that all rights and remedies hereunder may be exercised solely by
Secured Party for the benefit of Lenders and Lender Counterparties in accordance
with the terms of this Section. Secured Party shall at all times be the same
Person that is Administrative Agent under the Credit Agreement. Written notice
of resignation by Administrative Agent pursuant to terms of the Credit Agreement
shall also constitute notice of resignation as Secured Party under this
Agreement; removal of Administrative Agent pursuant to the terms of the Credit
Agreement shall also constitute removal as Secured Party under this Agreement;
and appointment of a successor Administrative Agent pursuant to the terms of the
Credit Agreement shall also constitute appointment of a successor Secured Party
under this Agreement. Upon the acceptance of any appointment as Administrative
Agent under the terms of the Credit Agreement by a successor Administrative
Agent, that successor Administrative Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring or
removed Secured Party under this Agreement, and the retiring or


                                      I-26
<PAGE>   186

removed Secured Party under this Agreement shall promptly (i) transfer to such
successor Secured Party all sums, securities and other items of Collateral held
hereunder, together with all records and other documents necessary or
appropriate in connection with the performance of the duties of the successor
Secured Party under this Agreement, and (ii) execute and deliver to such
successor Secured Party such amendments to financing statements, and take such
other actions, as may be necessary or appropriate in connection with the
assignment to such successor Secured Party of the security interests created
hereunder, whereupon such retiring or removed Secured Party shall be discharged
from its duties and obligations under this Agreement. After any retiring or
removed Administrative Agent 's resignation or removal hereunder as Secured
Party, the provisions of this Agreement shall inure to its benefit as to any
actions taken or omitted to be taken by it under this Agreement while it was
Secured Party hereunder. No Grantor shall enter into any agreement with any
other Person relating to Investment Property pursuant to which such other Person
agrees to comply with entitlement orders (as defined in Section 8-102(a)(8) of
the New York UCC with respect to such Investment Property.

SECTION 9. CONTINUING SECURITY INTEREST; TRANSFER OF LOANS

         This Agreement shall create a continuing security interest in the
Collateral and shall (a) remain in full force and effect until the payment in
full of the Secured Obligations (other than inchoate indemnification
obligations with respect to claims, losses or liabilities which have not yet
arisen and are not yet due and payable) and the cancellation or termination of
the Commitments, (b) be binding upon each Grantor, its successors and assigns,
and (c) inure, together with the rights and remedies of Secured Party hereunder,
to the benefit of Secured Party and its successors, transferees and assigns.
Without limiting the generality of the foregoing clause (c), but subject to the
terms of the Credit Agreement, any Lender may assign or otherwise transfer any
Loans held by it to any other Person, and such other Person shall thereupon
become vested with all the benefits in respect thereof granted to Lenders herein
or otherwise. Upon the payment in full of all Secured Obligations (other than
inchoate indemnification obligations with respect to claims, losses or
liabilities which have not yet arisen and are not yet due and payable) and the
cancellation or termination of the Commitments, the security interest granted
hereby shall terminate hereunder and of record and all rights to the Collateral
shall revert to Grantor. Upon any such termination Secured Party will, at
Grantors' expense, execute and deliver to Grantors such documents as Grantors
shall reasonably request to evidence such termination.

SECTION 10. STANDARD OF CARE; SECURED PARTY MAY PERFORM

         The powers conferred on Secured Party hereunder are solely to protect
its interest in the Collateral and shall not impose any duty upon it to exercise
any such powers. Except for the exercise of reasonable care in the custody of
any Collateral in its possession and the accounting for moneys actually received
by it hereunder, Secured Party shall have no duty as to any Collateral or as to
the taking of any necessary steps to preserve rights against prior parties or
any other rights pertaining to any Collateral. Secured Party shall be deemed to
have exercised


                                      I-27
<PAGE>   187

reasonable care in the custody and preservation of Collateral in its possession
if such Collateral is accorded treatment substantially equal to that which
Secured Party accords its own property. If any Grantor fails to perform any
agreement contained herein, Secured Party may itself perform, or cause
performance of, such agreement, and the expenses of Secured Party incurred in
connection therewith shall be payable by each Grantor under Section 10.2 of the
Credit Agreement.

SECTION 11. INDEMNITY AND EXPENSES

         (a) Each Grantor agrees:

                  (i) to indemnify Secured Party and each Secured Party from and
         against any and all claims, losses and liabilities in any way relating
         to, growing out of or resulting from this Agreement and the
         transactions contemplated hereby (including without limitation
         enforcement of this Agreement) in accordance with the terms and
         conditions of the Credit Agreement, except to the extent such claims,
         losses or liabilities result from Secured Party's or such Secured
         Party's gross negligence, bad faith, or willful misconduct as
         determined by a court of competent jurisdiction; and

                  (ii) to pay to Secured Party promptly following written demand
         the amount of any and all reasonable costs and reasonable expenses,
         including the reasonable fees and expenses of its counsel and of any
         experts and agents in accordance with the terms and conditions of the
         Credit Agreement.

         (b) The obligations of each Grantor in this Section 11 shall survive
the termination of this Agreement and the discharge of such Grantor's other
obligations under this Agreement, the Hedge Agreements, the Credit Agreement and
any other Credit Documents.

SECTION 12. MISCELLANEOUS

         Any notice required or permitted to be given under this Agreement shall
be given in accordance with Section 10.1 of the Credit Agreement. No failure or
delay on the part of Secured Party in the exercise of any power, right or
privilege hereunder or under any other Credit Document shall impair such power,
right or privilege or be construed to be a waiver of any default or acquiescence
therein, nor shall any single or partial exercise of any such power, right or
privilege preclude other or further exercise thereof or of any other power,
right or privilege. All rights and remedies existing under this Agreement and
the other Credit Documents are cumulative to, and not exclusive of, any rights
or remedies otherwise available. In case any provision in or obligation under
this Agreement shall be invalid, illegal or unenforceable in any jurisdiction,
the validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby. All covenants hereunder shall be
given independent effect so that if a


                                      I-28
<PAGE>   188

particular action or condition is not permitted by any of such covenants, the
fact that it would be permitted by an exception to, or would otherwise be within
the limitations of, another covenant shall not avoid the occurrence of a Default
or an Event of Default if such action is taken or condition exists. This
Agreement shall be binding upon and inure to the benefit of Secured Party and
Grantors and their respective successors and assigns. No Grantor shall, without
the prior written consent of Secured Party, assign any right, duty or obligation
hereunder. This Agreement and the other Credit Documents embody the entire
agreement and understanding between Grantors and Secured Party and supersede all
prior agreements and understandings between such parties relating to the subject
matter hereof and thereof. Accordingly, the Credit Documents may not be
contradicted by evidence of prior, contemporaneous or subsequent oral
agreements of the parties. There are no unwritten oral agreements between the
parties. This Agreement may be executed in one or more counterparts and by
different parties hereto in separate counterparts, each of which when so
executed and delivered shall be deemed an original, but all such counterparts
together shall constitute but one and the same instrument; signature pages may
be detached from multiple separate counterparts and attached to a single
counterpart so that all signature pages are physically attached to the same
document.

         THE PROVISIONS OF THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF EACH
GRANTOR AND SECURED PARTY SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND
ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD
TO THE CONFLICT OF LAWS PRINCIPLES THEREOF.

         IN WITNESS WHEREOF, each Grantor and Secured Party have caused this
Agreement to be duly executed and delivered by their respective officers
thereunto duly authorized as of the date first written above.

hereafter to be made by any governmental authority pertaining to the Land,
Improvements, Fixtures or Personalty (the "Condemnation Awards"). As used in

preserve and protect the first lien and security interest status of this
Mortgage and the other Credit Documents. If any lien or security interest other

shall promptly, and at its expense, (i) give Mortgagee a detailed written notice
of such lien or security interest (including origin, amount and other terms),
and (ii) at Mortgagor's election, pay the underlying claim in full or take such
other action so as to cause it to be released or contest the same in compliance
with the requirements of the Credit Agreement.

         3.3. [Reserved.]

         3.4. Replacement of Fixtures and Personalty. Mortgagor shall not,
without the prior written consent of Mortgagee and subject to the provisions of

provisions of the Credit Agreement, to inspect the Mortgaged Property and all

Leasehold Properties, to conduct such environmental and engineering studies as
Mortgagee may require; provided, such inspections and studies shall not
materially interfere with the use and operation of the Mortgaged Property.

         3.6. Covenants Running with the Land. All Obligations contained in this
Mortgage are intended by Mortgagor and Mortgagee to be, and shall be construed
as, covenants running with the Mortgaged Property. As used herein, "Mortgagor"

Agreement and the other Credit Documents; however, no such party shall be
entitled to any rights thereunder without the prior written consent of
Mortgagee. In addition, all of the covenants of Mortgagor in any Credit Document
party thereto are incorporated herein by reference and, together with covenants
in this Section, shall be covenants running with the land.

         3.7. Condemnation Awards and Insurance Proceeds. Subject to the
provisions of the Credit Agreement, Mortgagor (i) assigns all awards and
compensation to which it is entitled for any condemnation or other taking, or
any purchase in lieu thereof, to Mortgagee and authorizes Mortgagee to collect
and receive such awards and compensation and to give proper receipts and
acquittances therefor, subject to the terms of the Credit Agreement, (ii)
assigns to Mortgagee all proceeds of any insurance policies insuring against
loss or damage to the Mortgaged Property, (iii) authorizes Mortgagee to collect
and receive such proceeds and authorizes and directs the issuer of each of such
insurance policies to make payment for all such losses directly to Mortgagee,
instead of to Mortgagor and Mortgagee jointly.

         [3.8. Certain Leasehold Representations, Warranties and Covenants.

         (a) Mortgagor represents and warrants to Mortgagee that (i) the Subject
Lease is unmodified and in full force and effect, (ii) all rent and other
charges therein have been paid to the extent they are payable to the date
hereof, (iii) Mortgagor enjoys the quiet and peaceful possession of the property
demised thereby, (iv) to the best of its knowledge, Mortgagor is not in default
under any of the terms thereof and there are no circumstances which, with the
passage of time or the giving of notice or both, would constitute an event of
default thereunder, (v) to the best of Mortgagor's knowledge, the lessor
thereunder is not in default under any of the terms or provisions thereof on the
part of the lessor to be observed or performed. Mortgagor shall promptly pay,
when due and payable, the rent and other charges payable pursuant to the Subject
Lease, and will timely perform and observe all of the other terms, covenants and
conditions required to be performed and observed by Mortgagor as lessee under
the Subject Lease. Mortgagor shall notify Mortgagee in writing of any material
default by Mortgagor in the performance or observance of any terms, covenants or
conditions on the part of Mortgagor to be performed or observed under the
Subject Lease within five Business Days after Mortgagor knows of such default.
Mortgagor shall, immediately upon receipt thereof, deliver a copy of each
material notice given to Mortgagor by the lessor pursuant to the Subject Lease
and promptly notify Mortgagee in writing of any default by the lessor in the
performance or observance of any of the terms, covenants or conditions on the
part of the lessor to be performed or observed thereunder. Unless required under
the terms of the Subject Lease, Mortgagor shall not, without the prior written
consent of Mortgagee (which may be granted or withheld in Mortgagee's sole and
absolute discretion) terminate, modify or surrender the Subject Lease, and any
such attempted termination, modification or surrender without Mortgagee's
written consent shall be void; provided that renewal options may be exercised at
Mortgagor's option. Mortgagor shall, within twenty (20) days after written
request from Mortgagee, use its reasonable best efforts to obtain from the
lessor and deliver to Mortgagee a certificate setting forth the name of the
tenant


                                      J-5
<PAGE>   206

thereunder and stating that the Subject Lease is in full force and effect, is
unmodified or, if the Subject Lease has been modified, the date of each
modification (together with copies of each such modification), that no notice of
termination thereon has been served on Mortgagor, stating that no default or
event which with notice or lapse of time (or both) would become a default is
existing under the Subject Lease, stating the date to which rent has been paid,
and specifying the nature of any defaults, if any, and containing such other
statements and representations as may be requested by Mortgagee.

         (b) So long as any of the Indebtedness or the Obligations remain unpaid
or unperformed, the fee title to and the leasehold estate in the premises
subject to each Subject Lease shall not merge but shall always be kept separate
and distinct notwithstanding the union of such estates in the lessor or
Mortgagor, or in a third party, by purchase or otherwise. If Mortgagor acquires
the fee title or any other estate, title or interest in the property demised by
the Subject Lease, or any part thereof, the lien of this Mortgage shall attach
to, cover and be a lien upon such acquired estate, title or interest and the
same shall thereupon be and become a part of the Mortgaged Property with the
same force and effect as if specifically encumbered herein. Mortgagor agrees to
execute all instruments and documents that Mortgagee may reasonably require to
ratify, confirm and further evidence the lien of this Mortgage on the acquired
estate, title or interest. Furthermore, Mortgagor hereby appoints Mortgagee as
its true and lawful attorney-in-fact to execute and deliver, following the
occurrence and during the continuance of an Event of Default, all such
instruments and documents in the name and on behalf of Mortgagor. This power,
being coupled with an interest, shall be irrevocable as long as any portion of
the Indebtedness remains unpaid.

         (c) If the Subject Lease shall be terminated prior to the natural
expiration of its term due to default by Mortgagor or any tenant thereunder, and
if, pursuant to the provisions of the Subject Lease, Mortgagee or its designee
shall acquire from the lessor a new lease of the premises subject to the Subject
Lease, Mortgagor shall have no right, title or interest in or to such new lease
or the leasehold estate created thereby, or renewal privileges therein
contained.

         (d) Notwithstanding anything to the contrary contained herein, this
Mortgage shall not constitute an assignment of any Subject Lease within the
meaning of any provision thereof prohibiting its assignment and Mortgagee shall
have no liability or obligation thereunder by reason of its acceptance of this
Mortgage. Mortgagee shall be liable for the obligations of the tenant arising
out of any Subject Lease for only that period of time for which Mortgagee is in
possession of the premises demised thereunder or has acquired, by foreclosure or
otherwise, and is holding all of Mortgagor's right, title and interest therein.]

SECTION 4. DEFAULT AND FORECLOSURE

         4.1. Remedies. If an Event of Default exists, Mortgagee may at
Mortgagee's election, exercise any or all of the following rights, remedies and
recourses (which are in addition to all rights and remedies available under the
Credit Agreement and the Pledge and Security Agree-


                                      J-6
<PAGE>   207

ment): (i) enter the Mortgaged Property and take exclusive possession thereof
and of all books, records and accounts relating thereto or located thereon and
(ii) if Mortgagor remains in possession of the Mortgaged Property after an Event
of Default and without Mortgagee's prior written consent, Mortgagee may invoke
any legal remedies to dispossess Mortgagor; (iii) hold, lease, develop, manage,
operate or otherwise use the Mortgaged Property upon such terms and conditions
as Mortgagee may deem reasonable under the circumstances (making such repairs,
alternations, additions and improvements and taking other actions, from time to
time, as Mortgagee deems necessary or desirable), and apply all Rents and other
amounts collected by Mortgagee in connection therewith in accordance with the
provisions hereof; (iv) institute proceedings for the complete foreclosure of
this Mortgage, either by judicial action or by power of sale, in which case the
Mortgaged Property may be sold for cash or credit in one or more parcels. With
respect to any notices required or permitted under the UCC, Mortgagor agrees
that ten (10) days' prior written notice shall be deemed commercially
reasonable. At any such sale by virtue of any judicial proceedings, power of
sale, or any other legal right, remedy or recourse, the title to and right of
possession of any such property shall pass to the purchaser thereof, and to the
fullest extent permitted by law, Mortgagor shall be completely and irrevocably
divested of all of its right, title, interest, claim, equity, equity of
redemption, and demand whatsoever, either at law or in equity, in and to the
property sold and such sale shall be a perpetual bar both at law and in equity
against Mortgagor, and against all other Persons claiming or to claim the
property sold or any part thereof, by, through or under Mortgagor. Mortgagee may
be a purchaser at such sale and if Mortgagee is the highest bidder, Mortgagee
may credit the portion of the purchase price that would be distributed to
Mortgagee against the Indebtedness in lieu of paying cash. In the event this
Mortgage is foreclosed by judicial action, appraisement of the Mortgaged
Property is waived and Mortgagee may make application to a court of competent
jurisdiction for, and obtain from such court as a matter of strict right and
without notice to Mortgagor or regard to the adequacy of the Mortgaged Property
for the repayment of the Indebtedness, the appointment of a receiver of the
Mortgaged Property, and Mortgagor irrevocably consents to such appointment. Any
such receiver shall have all the usual powers and duties of receivers in similar
cases, including the full power to rent, maintain and otherwise operate the
Mortgaged Property upon such terms as may be approved by the court, and shall
apply such Rents in accordance with the provisions hereof; and/or exercise all
other rights, remedies and recourses granted under the Credit Documents or
otherwise available at law or in equity.

         4.2. Separate Sales. The Mortgaged Property may be sold in one or more
parcels and in such manner and order as Mortgagee in its sole discretion may
elect; the right of sale arising out of any Event of Default shall not be
exhausted by any one or more sales.

         4.3. Remedies Cumulative, Concurrent and Nonexclusive. Mortgagee shall
have all rights, remedies and recourses granted in the Credit Documents and
available at law or equity (including the UCC), which rights (i) shall be
cumulated and concurrent, (ii) may be pursued separately, successively or
concurrently against Mortgagor or others obligated under the Credit Documents,
or against the Mortgaged Property, or against any one or more of them, at the
sole discretion of Mortgagee, (iii) may be exercised as often as occasion
therefor shall arise, and the


                                      J-7
<PAGE>   208

exercise or failure to exercise any of them shall not be construed as a waiver
or release thereof or of any other right, remedy or recourse, and (iv) are
intended to be, and shall be, nonexclusive. No action by Mortgagee in the
enforcement of any rights, remedies or recourses under the Credit Documents or
otherwise at law or equity shall be deemed to cure any Event of Default.

         4.4. Release of and Resort to Collateral. Mortgagee may release,
regardless of consideration and without the necessity for any notice to or
consent by the holder of any subordinate lien on the Mortgaged Property, any
part of the Mortgaged Property without, as to the remainder, in any way
impairing, affecting, subordinating or releasing the lien or security interest
created in or evidenced by the Credit Documents or their status as a first and
prior lien and security interest in and to the Mortgaged Property. For payment
of the Indebtedness, Mortgagee may resort to any other security in such order
and manner as Mortgagee may elect.

         4.5. Waiver of Redemption, Notice and Marshalling of Assets. To the
fullest extent permitted by law, Mortgagor hereby irrevocably and
unconditionally waives and releases (i) all benefit that might accrue to
Mortgagor by virtue of any present or future statute of limitations or law or
judicial decision exempting the Mortgaged Property from attachment, levy or sale
on execution or providing for any stay of execution, exemption from civil
process, redemption or extension of time for payment, (ii) all notices of any
Event of Default or of Mortgagee's election to exercise or the actual exercise
of any right, remedy or recourse provided for under the Credit Documents, and
(iii) any right to a marshalling of assets or a sale in inverse order of
alienation.

         4.6. Discontinuance of Proceedings. If Mortgagee shall have proceeded
to invoke any right, remedy or recourse permitted under the Credit Documents and
shall thereafter elect to discontinue or abandon it for any reason, Mortgagee
shall have the unqualified right to do so and, in such an event, Mortgagor and
Mortgagee shall be restored to their former positions with respect to the
Indebtedness, the Obligations, the Credit Documents, the Mortgaged Property and
otherwise, and the rights, remedies, recourses and powers of Mortgagee shall
continue as if the right, remedy or recourse had never been invoked, but no such
discontinuance or abandonment shall waive any Event of Default which may then
exist or the right of Mortgagee thereafter to exercise any right, remedy or
recourse under the Credit Documents for such Event of Default.

         4.7. Application of Proceeds. The proceeds of any sale of, and the
Rents and other amounts generated by the holding, leasing, management, operation
or other use of the Mortgaged Property, shall be applied by Mortgagee (or the
receiver, if one is appointed) in the following order unless otherwise required
by applicable law: first, to the payment of the actual out of pocket costs and
expenses of taking possession of the Mortgaged Property and of holding, using,
leasing, repairing, improving and selling the same, including, without
limitation (i) receiver's fees and expenses, including the repayment of the
amounts evidenced by any receiver's certificates, (ii) court costs, (iii)
reasonable attorneys' and accountants' fees and expenses, (iv) costs of
advertisement, and (v) the payment of all rent and other charges under the
Subject Lease; and second, as provided in Section 2.16 of the Credit Agreement.


                                      J-8
<PAGE>   209

         4.8. Occupancy After Foreclosure. Any sale of the Mortgaged Property or
any part thereof will divest all right, title and interest of Mortgagor in and
to the property sold. Subject to applicable law, any purchaser at a foreclosure
sale will receive immediate possession of the property purchased. If Mortgagor
retains possession of such property or any part thereof subsequent to such sale,
Mortgagor will be considered a tenant at sufferance of the purchaser, and will,
if Mortgagor remains in possession after demand to remove, be subject to
eviction and removal, forcible or otherwise, with or without process of law.

         4.9. Additional Advances and Disbursements; Costs of Enforcement. If
any Event of Default exists, Mortgagee shall have the right, but not the
obligation, to cure such Event of Default in the name and on behalf of
Mortgagor. All sums advanced and expenses incurred at any time by Mortgagee
under this Section, or otherwise under this Mortgage or any of the other Credit
Documents or applicable law, shall bear interest from the date that such sum is
advanced or expense incurred, to and including the date of reimbursement,
computed at the rate or rates at which interest is then computed on the
Indebtedness, and all such sums, together with interest thereon, shall be
secured by this Mortgage. Mortgagor shall pay all reasonable out of pocket
expenses (including reasonable attorneys' fees and expenses) of or incidental to
the perfection and enforcement of this Mortgage and the other Credit Documents,
or the enforcement, compromise or settlement of the Indebtedness or any claim
under this Mortgage and the other Credit Documents, and for the curing thereof,
or for defending or asserting the rights and claims of Mortgagee in respect
thereof, by litigation or otherwise.

         4.10. No Mortgagee in Possession. Neither the enforcement of any of the
remedies under this Section, the assignment of the Rents and Leases under
Section 5, the security interests under Section 6, nor any other remedies
afforded to Mortgagee under the Credit Documents, at law or in equity shall
cause Mortgagee to be deemed or construed to be a mortgagee in possession of the
Mortgaged Property, to obligate Mortgagee to lease the Mortgaged Property or
attempt to do so, or to take any action, incur any expense, or perform or
discharge any obligation, duty or liability whatsoever under any of the Leases
or otherwise.

         4.11. Waiver of Stay, Moratorium and Similar Rights. Mortgagor agrees,
to the full extent that it may lawfully do so, that it will not at any time
insist upon or plead or in any way take advantage of any stay, marshalling of
assets, extension, redemption or moratorium law now or hereafter in force and
effect so as to prevent or hinder the enforcement of the provisions of this
Mortgage or the Indebtedness secured hereby, or any agreement between Mortgagor
and Mortgagee or any rights or remedies of Mortgagee.

SECTION 5. ASSIGNMENT OF RENTS AND LEASES

         5.1. Assignment. In furtherance of and in addition to the assignment
made by Mortgagor herein, Mortgagor hereby absolutely and unconditionally
assigns, sells, transfers and conveys to Mortgagee all of its right, title and
interest in and to all Leases, whether now existing or hereafter entered into,
and all of its right, title and interest in and to all Rents. This assignment


                                      J-9
<PAGE>   210

is an absolute assignment and not an assignment for additional security only. So
long as no Event of Default shall have occurred and be continuing, Mortgagor
shall have a revocable license from Mortgagee to exercise all rights extended to
the landlord under the Leases, including the right to receive and collect all
Rents and to hold the Rents in trust for use in the payment and performance of
the Obligations and to otherwise use the same. The foregoing license is granted
subject to the conditional limitation that no Event of Default shall have
occurred and be continuing. Upon the occurrence and during the continuance of an
Event of Default, whether or not legal proceedings have commenced, and without
regard to waste, adequacy of security for the Obligations or solvency of
Mortgagor, the license herein granted shall automatically expire and terminate,
without notice by Mortgagee (any such notice being hereby expressly waived by
Mortgagor).

         5.2. Perfection Upon Recordation. Mortgagor acknowledges that Mortgagee
has taken all actions necessary to obtain, and that upon recordation of this
Mortgage Mortgagee shall have, to the extent permitted under applicable law and
subject to Permitted Liens, a valid and fully perfected, first priority, present
assignment of the Rents arising out of the Leases and all security for such
Leases. Mortgagor acknowledges and agrees that upon recordation of this Mortgage
Mortgagee's interest in the Rents shall be deemed to be fully perfected,
"choate" and enforced as to Mortgagor and all third parties, including, without
limitation, any subsequently appointed trustee in any case under Title 11 of the
United States Code (the "Bankruptcy Code"), without the necessity of commencing
a foreclosure action with respect to this Mortgage, making formal demand for the
Rents, obtaining the appointment of a receiver or taking any other affirmative
action.

         5.3. Bankruptcy Provisions. Without limitation of the absolute nature
of the assignment of the Rents hereunder, Mortgagor and Mortgagee agree that (i)
this Mortgage shall constitute a "security agreement" for purposes of Section
552(b) of the Bankruptcy Code, (ii) the security interest created by this
Mortgage extends to property of Mortgagor acquired before the commencement of a
case in bankruptcy and to all amounts paid as Rents, and (iii) such security
interest shall extend to all Rents acquired by the estate after the commencement
of any case in bankruptcy.

         5.4. No Merger of Estates. So long as any part of the Indebtedness or
the Obligations secured hereby remain unpaid and undischarged, the fee and
leasehold estates to the Mortgaged Property shall not merge, but shall remain
separate and distinct, notwithstanding the union of such estates either in
Mortgagor, Mortgagee, any tenant or any third party by purchase or otherwise.


                                      J-10
<PAGE>   211

SECTION 6. SECURITY AGREEMENT

         6.1. Security Interest. This Mortgage constitutes a "security
agreement" on personal property within the meaning of the UCC and other
applicable law and with respect to the Personalty, Fixtures, Leases, Rents,
Deposit Accounts, Property Agreements, Tax Refunds, Proceeds, Insurance and
Condemnation Awards. To this end, Mortgagor grants to Mortgagee a first and
prior security interest in the Personalty, Fixtures, Leases, Rents, Deposit
Accounts, Property Agreements, Tax Refunds, Proceeds, Insurance, Condemnation
Awards and all other Mortgaged Property which is personal property to secure the
payment of the Indebtedness and performance of the Obligations, and agrees that
Mortgagee shall have all the rights and remedies of a secured party under the
UCC with respect to such property. Any notice of sale, disposition or other
intended action by Mortgagee with respect to the Personalty, Fixtures, Leases,
Rents, Deposit Accounts, Property Agreements, Tax Refunds, Proceeds, Insurance
and Condemnation Awards sent to Mortgagor at least ten (10) days prior to any
action under the UCC shall constitute reasonable notice to Mortgagor.

         6.2. Financing Statements. Mortgagor shall execute and deliver to
Mortgagee, in form and substance satisfactory to Mortgagee, such financing
statements and such further assurances as Mortgagee may, from time to time,
reasonably consider necessary to create, perfect and preserve Mortgagee's
security interest hereunder and Mortgagee may cause such statements and
assurances to be recorded and filed, at such times and places as may be required
or permitted by law to so create, perfect and preserve such security interest.
Mortgagor's chief executive office is at the address set forth in Appendix B of
the Credit Agreement.

         6.3. Fixture Filing. This Mortgage shall also constitute a "fixture
filing" for the purposes of the UCC against all of the Mortgaged Property which
is or is to become fixtures. Information concerning the security interest herein
granted may be obtained at the addresses of Debtor (Mortgagor) and Secured Party
(Mortgagee) as set forth on the cover hereof.

SECTION 7. ATTORNEY-IN-FACT

         Mortgagor hereby irrevocably appoints Mortgagee and its successors and
assigns, as its attorney-in-fact, which agency is coupled with an interest and
with full power of substitution, (i) to execute and/or record any notices of
completion, cessation of labor or any other notices that Mortgagee deems
appropriate to protect Mortgagee's interest, if Mortgagor shall fail to do so
within ten (10) days after written request by Mortgagee, (ii) upon the issuance
of a deed pursuant to the foreclosure of this Mortgage or the delivery of a deed
in lieu of foreclosure, to execute all instruments of assignment, conveyance or
further assurance with respect to the Leases, Rents, Deposit Accounts, Property
Agreements, Tax Refunds, Proceeds, Insurance and Condemnation Awards in favor of
the grantee of any such deed and as may be necessary or desirable for such
purpose, (iii) to prepare, execute and file or record financing statements,
continuation statements, applications for registration and like papers necessary
to create, perfect or preserve Mortgagee's security interests and rights in or
to any of the Mortgaged Property upon Mortgagor's failure to


                                      J-11
<PAGE>   212

do so, and (iv) while any Event of Default exists, to perform any obligation of
Mortgagor hereunder; provided, (a) Mortgagee shall not under any circumstances
be obligated to perform any obligation of Mortgagor; (b) any sums advanced by
Mortgagee in such performance shall be added to and included in the Indebtedness
and shall bear interest at the rate or rates at which interest is then computed
on the Indebtedness; (c) Mortgagee as such attorney-in-fact shall only be
accountable for such funds as are actually received by Mortgagee; and (d)
Mortgagee shall not be liable to Mortgagor or any other person or entity for any
failure to take any action which it is empowered to take under this Section.

SECTION 8. MORTGAGEE AS AGENT

         Mortgagee has been appointed to act as Mortgagee hereunder by Lenders
and, by their acceptance of the benefits hereof, Lender Counterparties.
Mortgagee shall be obligated, and shall have the right hereunder, to make
demands, to give notices, to exercise or refrain from exercising any rights, and
to take or refrain from taking any action (including the release or substitution
of Mortgaged Property), solely in accordance with this Mortgage and the Credit
Agreement; provided, Mortgagee shall exercise, or refrain from exercising, any
remedies provided for herein in accordance with the instructions of (i)
Requisite Lenders, or (ii) after payment in full of all Obligations under the
Credit Agreement and the other Credit Documents, the holders of a majority of
the aggregate notional amount (or, with respect to any Hedge Agreement that has
been terminated in accordance with its terms, the amount then due and payable
(exclusive of expenses and similar payments but including any early termination
payments then due) under such Hedge Agreement) under all Hedge Agreements
(Requisite Lenders or, if applicable, such holders being referred to herein as
"Requisite Obligees"). In furtherance of the foregoing provisions of this
Section, each Lender Counterparty, by its acceptance of the benefits hereof,
agrees that it shall have no right individually to realize upon any of the
Mortgaged Property, it being understood and agreed by such Lender Counterparty
that all rights and remedies hereunder may be exercised solely by Mortgagee for
the benefit of Lenders and Lender Counterparties in accordance with the terms of
this Section. Mortgagee shall at all times be the same Person that is
Administrative Agent under the Credit Agreement. Written notice of resignation
by Administrative Agent pursuant to terms of the Credit Agreement shall also
constitute notice of resignation as Mortgagee under this Agreement; removal of
Administrative Agent pursuant to the terms of the Credit Agreement shall also
constitute removal as Mortgagee under this Agreement; and appointment of a
successor Administrative Agent pursuant to the terms of the Credit Agreement
shall also constitute appointment of a successor Mortgagee under this Agreement.
Upon the acceptance of any appointment as Administrative Agent under the terms
of the Credit Agreement by a successor Administrative Agent, that successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring or removed Mortgagee under
this Agreement, and the retiring or removed Mortgagee under this Agreement shall
promptly (i) transfer to such successor Mortgagee all sums, securities and other
items of Mortgaged Property held hereunder, together with all records and other
documents necessary or appropriate in connection with the performance of the
duties of the successor Mortgagee under this Mortgage, and (ii) execute and


                                      J-12
<PAGE>   213

deliver to such successor Mortgagee such amendments to financing statements, and
take such other actions, as may be necessary or appropriate in connection with
the assignment to such successor Mortgagee of the security interests created
hereunder, whereupon such retiring or removed Mortgagee shall be discharged from
its duties and obligations under this Mortgage. After any retiring or removed
Administrative Agent's resignation or removal hereunder as Mortgagee, the
provisions of this Mortgage shall inure to its benefit as to any actions taken
or omitted to be taken by it under this Mortgage while it was Mortgagee
hereunder.

SECTION 9. LOCAL LAW PROVISIONS

         [To be provided, if any, by local counsel.]

SECTION 10. MISCELLANEOUS

         Any notice required or permitted to be given under this Mortgage shall
be given in accordance with Section 10.1 of the Credit Agreement. No failure or
delay on the part of Mortgagee in the exercise of any power, right or privilege
hereunder or under any other Credit Document shall impair such power, right or
privilege or be construed to be a waiver of any default or acquiescence therein,
nor shall any single or partial exercise of any such power, right or privilege
preclude other or further exercise thereof or of any other power, right or
privilege. All rights and remedies existing under this Mortgage and the other
Credit Documents are cumulative to, and not exclusive of, any rights or remedies
otherwise available. In case any provision in or obligation under this Mortgage
shall be invalid, illegal or unenforceable in any jurisdiction, the validity,
legality and enforceability of the remaining provisions or obligations, or of
such provision or obligation in any other jurisdiction, shall not in any way be
affected or impaired thereby. Subject to the provisions of the Credit Agreement,
all covenants hereunder shall be given independent effect so that if a
particular action or condition is not permitted by any of such covenants, the
fact that it would be permitted by an exception to, or would otherwise be within
the limitations of, another covenant shall not avoid the occurrence of a Default
or an Event of Default if such action is taken or condition exists. This
Mortgage shall be binding upon and inure to the benefit of Mortgagee and
Mortgagor and their respective successors and assigns. Mortgagor shall not,
without the prior written consent of Mortgagee, assign any rights, duties or
obligations hereunder. Upon payment in full of the Indebtedness and performance
in full of the Obligations (other than inchoate indemnification obligations with
respect to claims, losses or liabilities which have not yet arisen and are not
yet due and payable), Mortgagee, at Mortgagor's expense, shall release the liens
and security interests created by this Mortgage or reconvey the Mortgaged
Property to Mortgagor. This Mortgage and the other Credit Documents embody the
entire agreement and understanding between Mortgagee and Mortgagor and supersede
all prior agreements and understandings between such parties relating to the
subject matter hereof and thereof. Accordingly, the Credit Documents may not be
contradicted by evidence of prior, contemporaneous or subsequent oral agreements
of the parties. There are no unwritten oral agreements between the parties.

as of ___________ and entered into by __________________, a ___________
("Landlord"), to and for the benefit of TORONTO DOMINION TEXAS, INC., as

                                    RECITALS:

                  WHEREAS, _______________, a ________________ ("Tenant"), has
possession of and occupies all or a portion of the property described on Exhibit

                  WHEREAS, Tenant's interest in the Premises arises under the

forth therein, to take possession of, and otherwise assert control over, the
Premises;

                  WHEREAS, reference is made to that certain Credit and Guaranty
Agreement, dated as of April __, 1999 (as it may be amended, supplemented or

as Guarantors, Lenders, Goldman Sachs Credit Partners L.P. ("GSCP"), as
Syndication Agent, Toronto Dominion (Texas), Inc., as Administrative Agent,
Morgan Stanley Senior Funding, Inc., as Documentation Agent, and GSCP and TD
Securities (USA) Inc., as Co-Lead Arrangers (capitalized terms used herein and
not otherwise defined herein shall have the meanings ascribed thereto in the
Credit Agreement or the Pledge and Security Agreement (as defined in the Credit
Agreement), as applicable), pursuant to which Tenant has executed a security
agreement, mortgages, deeds of trust, deeds to secure debt and assignments of
rents and leases, and other collateral documents in relation to the Credit
Agreement;

                  WHEREAS, Tenant's repayment of the extensions of credit made
by Lenders under the Credit Agreement will be secured, in part, by all Inventory
of Tenant (including all Inventory of Tenant now or hereafter located on the
Premises (the "Subject Inventory")) and all Equipment used in Tenant's business
(including all Equipment of Tenant now or hereafter located on the Premises (the
"Subject Equipment" and, together with the Subject Inventory, the
"Collateral")); and

                  WHEREAS, Collateral Agent has requested that Landlord execute
this Agreement as a condition to the extension of credit to Tenant under the
Credit Agreement.

                  NOW, THEREFORE, in consideration of the premises and for other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, Landlord hereby covenants and agrees with Collateral Agent as
follows:

                  1. Landlord hereby (a) waives and releases unto Collateral
Agent and its successors and assigns any and all rights granted by or under any
present or future laws to levy or distraint for rent or any other charges which
may be due to Landlord against the Collateral, and any and all other claims,
liens and demands of every kind which it now has or may hereafter have against
the Collateral, and (b) agrees that any rights it may have in or to the
Collateral, no matter how arising (to the extent not effectively waived pursuant
to clause (a) of this paragraph 1), shall be second and subordinate to the
rights of Collateral Agent in respect thereof. Landlord acknowledges that the
Collateral is and will remain personal property and not fixtures even though it
may be affixed to or placed on the Premises.

                  2. Landlord certifies that (a) Landlord is the landlord under
the Lease, (b) the Lease is in full force and effect and has not been amended,
modified, or supplemented except as set forth on Exhibit B annexed hereto, (c)
to the knowledge of Landlord, there is no defense, offset, claim or counterclaim
by or in favor of Landlord against Tenant under the Lease or against the
obligations of Landlord under the Lease, (d) no notice of default has been given
under or in connection with the Lease which has not been cured, and Landlord has
no knowledge of the occurrence of any other default under or in connection with
the Lease, and (e) except as disclosed to Collateral Agent, no portion of the
Premises is encumbered in any way by any deed of trust or mortgage lien or
ground or superior lease.


                                      K-2

                  3. Landlord consents to the installation or placement of the
Collateral on the Premises, and Landlord grants to Collateral Agent,
exerciseable upon the occurrence and during the continuance of an Event of
Default under the Credit Agreement, a license to enter upon and into the
Premises to do any or all of the following with respect to the Collateral:
assemble, have appraised, display, remove, maintain, prepare for sale or lease,
repair, transfer, or sell (at public or private sale). In entering upon or into
the Premises, Collateral Agent hereby agrees to indemnify, defend and hold
Landlord harmless from and against any and all claims, judgments, liabilities,
costs and expenses incurred by Landlord caused solely by Collateral Agent's
entering upon or into the Premises and taking any of the foregoing actions with
respect to the Collateral. Such costs shall include any damage to the Premises
made by Collateral Agent in severing and/or removing the Collateral therefrom.

                  4. Landlord agrees that it will not prevent Collateral Agent
or its designee from entering upon the Premises at all reasonable times to
inspect or remove the Collateral. In the event that Landlord has the right to,
and desires to, obtain possession of the Premises (either through expiration of
the Lease or termination thereof due to the default of Tenant thereunder),
Landlord will deliver notice (the "Landlord's Notice") to Collateral Agent to
that effect. Within the 45 day period after Collateral Agent receives the
Landlord's Notice, Collateral Agent shall have the right, provided that an Event
of Default is continuing, but not the obligation, to cause the Collateral to be
removed from the Premises. During such 45 day period, Landlord will not remove
the Collateral from the Premises nor interfere with Collateral Agent's actions
in removing the Collateral from the Premises or Collateral Agent's actions in
otherwise enforcing its security interest in the Collateral. Notwithstanding
anything to the contrary in this paragraph, Collateral Agent shall at no time
have any obligation to remove the Collateral from the Premises.

                  5. Landlord shall send to Collateral Agent a copy of any
notice of default under the Lease sent by Landlord to Tenant. In addition,
Landlord shall send to Collateral Agent a copy of any notice received by
Landlord of a breach or default under any other lease, mortgage, deed of trust,
security agreement or other instrument to which Landlord is a party which may
affect Landlord's rights in, or possession of, the Premises.

                  6. All notices to Collateral Agent under this Agreement shall
be in writing and sent to Collateral Agent at its address set forth on the
signature page hereof by telefacsimile, by United States mail, or by overnight
delivery service.

                  7. The provisions of this Agreement shall continue in effect
until Landlord shall have received Collateral Agent's written certification that
all amounts advanced under the Credit Agreement have been paid in full.

                  8. This Agreement and the rights and obligations of the
parties hereunder shall be governed by, and shall be construed and enforced in
accordance with, the internal laws of the State of New York, without regard to
conflicts of laws principles.

[Local Telephone Company]
[address]

         Reference is made to the Interconnection Agreement dated [ ] between
[Local Telephone Company] and [____________] (the "Agreement").

         Pursuant to Section [ ] of the Agreement, Allegiance requests your
consents to the Assignment of the Agreement to Toronto Dominion (Texas), Inc.,
its successors and assigns ("TD"), as administrative agent on behalf of secured
lenders as collateral for a financing to be entered into on or about April 1,
1999. In the event of a default by Allegiance or any of its subsidiaries under
the financing, [Local Telephone Company] agrees that TD, as administrative agent
or its designees may exercise any of the rights and privileges of Allegiance
under the Agreement, including entering into [Local Telephone Company's]
premises, and may request an assignment of the Agreement to a third party. [As
provided in Section [ ] of the Agreement, your consent to such an assignment is
subject to the provision of reasonable evidence of the assignee's resources,
ability and authority to perform under the Agreement].

         As you know, the FCC took action on March 18, 1999 to ensure local
competition and the reasonable cooperation of RBOCs in connection with
collocation arrangements. We therefore request your consent to the foregoing as
promptly as possible.

                                       Very truly yours,


                                       [                      ]
