                                CREDIT AGREEMENT

         THIS AGREEMENT is entered into as of August 24, 2001, between
AFFILIATED COMPUTER SERVICES, INC., a Delaware corporation (the "BORROWER"), the
Lenders (as defined below), BEAR STEARNS CORPORATE LENDING INC., as
Administrative Agent and Syndication Agent for the Lenders, BEAR, STEARNS & CO.
INC., as Bookrunner and Co-Lead Arranger, WELLS FARGO BANK TEXAS, NATIONAL
ASSOCIATION, as Documentation Agent and Co-Lead Arranger, and the Subsidiary
Guarantors (defined below).

         The Borrower has entered into a Stock Purchase Agreement, dated as of
July 18, 2001, as amended (the "STOCK PURCHASE AGREEMENT"), with Lockheed Martin
Corporation and Lockheed Martin Investments, Inc. (collectively, the "SELLER")
pursuant to which the Borrower has agreed to acquire all of the outstanding
capital stock of Lockheed Martin IMS Corporation ("IMS") for total cash
consideration of $825,000,000 (subject to adjustment as provided in the Stock
Purchase Agreement) (the "IMS ACQUISITION"). The Borrower has requested that the
Lenders extend a $550,000,000 senior credit facility to the Borrower to be used
by the Borrower to finance a portion of the cost of the IMS Acquisition and to
pay related fees and expenses. The Lenders are willing to extend the requested
credit facility on the terms and conditions of this Agreement.

         ACCORDINGLY, for adequate and sufficient consideration, the Borrower,
the Lenders, and the Agents agree as follows:

SECTION 1: DEFINITIONS AND TERMS.

         1.1 Definitions. As used in the Loan Documents:

         ACCOUNTS RECEIVABLE FINANCING means any transaction or series of
transactions that may be entered into by the Borrower or any of its Subsidiaries
pursuant to which the Borrower or any of its Subsidiaries may sell, convey,
grant a security interest in, or otherwise transfer, undivided percentage
interests in the Receivables Program Assets.

         ACCOUNTS RECEIVABLE FINANCING AMOUNT means, with respect to any
Accounts Receivable Financing and, without duplication, the aggregate
outstanding principal amount of the undivided percentage interests in the
Receivables Program Assets representing Rights to be paid a specified principal
amount from such Receivables Program Assets.

         ACQUISITION means any transaction or series of related transactions for
the purpose of, or resulting in, directly or indirectly, (a) the acquisition by
any Company of (i) all or substantially all of the assets of a Person, or (ii)
of any line of business, or division or selected assets of a Person, (b) the
acquisition by any Company of more than fifty percent (50%) of any class of
Voting Stock (or similar ownership interests) of any Person, or (c) a merger,
consolidation, amalgamation, or other combination by any Company with another
Person; provided that in any merger or similar transaction involving the
Borrower, the Borrower must be the surviving entity.

         ADJUSTED EBITDA means EBITDA adjusted (a) as permitted, and in
accordance with, Article 11 of Regulation S-X of the 1933 Act, and (b) to give
effect to any Permitted Acquisition which occurred during the period of
calculation, as if such Permitted Acquisition occurred on the

<PAGE>   9

first day of such period, by increasing, if positive, or decreasing, if
negative, EBITDA by the EBITDA of such newly-acquired business during such
period of calculation occurring prior to the date of such Permitted Acquisition;
provided that, if EBITDA is proposed to be adjusted for any Permitted
Acquisition, the consideration (in cash or any other consideration) for which
Acquisition is $50,000,000 or more, then to be included within the period of
calculation, and such adjustment: (i) the Person acquired or from which such
business was acquired shall have completed (prior to such Acquisition) audited
Financials covering periods within 15 months prior to the closing date of such
Permitted Acquisition accompanied by an unqualified opinion of an independent
certified public accountant; or (ii) the Borrower shall provide to the
Administrative Agent a written report completed by an independent certified
public accountant acceptable to the Administrative Agent which substantiates in
all material respects the EBITDA of the acquired entity or business using due
diligence procedures acceptable to the Administrative Agent.

         ADMINISTRATIVE AGENT means, at any time, Bear Stearns Corporate Lending

SECTION 2: COMMITMENTS. Subject to the provisions in the Loan Documents, each
Lender severally but not jointly agrees to extend credit to the Borrower in
accordance with the following provisions.

         2.1 Term Commitments. Subject to the terms and conditions hereof, each
Lender severally agrees to make a term loan (a "TERM LOAN") to the Borrower on
the Closing Date in an

                                       19
<PAGE>   27

amount not to exceed the amount of the Commitment of such Lender. The Term Loans
may from time to time be LIBOR Borrowings or Base-Rate Borrowings, as determined
by the Borrower and notified to the Administrative Agent in accordance with
Sections 2.2 and 3.10.

         2.2 Procedure for Term Loan Borrowing. (a) The Borrower shall give the
Administrative Agent irrevocable notice (which notice must be received by the
Administrative Agent prior to 10:00 A.M., three business days prior to the
Closing Date, if all or any portion of the Term Loans are initially to be part
of a LIBOR Borrowing or one Business Day prior to the anticipated Closing Date,
otherwise) by delivering a Borrowing Request requesting that the Lenders make
the Term Loans on the Closing Date and specifying the amount to be borrowed.
Upon receipt of such notice the Administrative Agent shall promptly notify each
Lender thereof.

         (b) Funding. Each Lender shall remit its Pro Rata Part of each
requested Borrowing to the Administrative Agent's principal office in New York
City, in funds that are available for immediate use by the Administrative Agent
by 12:00 noon on the Borrowing Date. Subject to receipt of those funds, the
Administrative Agent shall (unless to its actual knowledge any of the applicable
conditions precedent have not been satisfied by the Borrower or waived by the
requisite Lenders under SECTION 14.8) make those funds available to the Borrower
by wiring the funds to or for the account of the Borrower at the direction of
the Borrower.

         (c) Funding Assumed. Absent contrary written notice from a Lender, the
Administrative Agent may assume that each Lender has made its Pro Rata Part of
the requested Borrowing available to the Administrative Agent on the applicable
Borrowing Date, and the Administrative Agent may, in reliance upon such
assumption (but shall not be required to), make available to the Borrower a
corresponding amount. If a Lender fails to make its Pro Rata Part of any
requested Borrowing available to the Administrative Agent on the applicable
Borrowing Date, the Administrative Agent may recover the applicable amount on
demand, (i) from that Lender together with interest, commencing on the Borrowing
Date and ending on (but excluding) the date the Administrative Agent recovers
the amount from that Lender, at an annual interest rate equal to the Federal
Funds Rate, or (i) if that Lender fails to pay its amount upon demand, then from
the Borrower. No Lender is responsible for the failure of any other Lender to
make its Pro Rata Part of any Borrowing available as required by SECTION 2.2(b);
provided, however, the failure of any Lender to make its Pro Rata Part of any
Borrowing so available does not excuse any other Lender from making Pro Rata
Part of any Borrowing so available.

SECTION 3: TERMS OF PAYMENT.

         3.1 Notes and Payments.

                  (a) Notes. The Term Loans shall, at the request of any Lender
         delivered to the Administrative Agent, be evidenced by a Note, payable
         to such Lender in the stated amount of its initial Commitment.

                  (b) Payment. The Borrower must make each payment and
         prepayment on the Obligation to the Administrative Agent's Funding
         Office in New York City in immediately available funds by 1:00 p.m. on
         the day due; otherwise, but subject to SECTION 3.8, those funds
         continue to accrue interest as if they were received on the next

                                       20
<PAGE>   28

         Business Day. The Administrative Agent shall promptly pay to each
         Lender the part of any payment or prepayment to which that Lender is
         entitled under this Agreement.

                  (c) Payment Assumed. Unless the Administrative Agent has
         received notice from the Borrower prior to the date on which any
         payment is due under this Agreement that the Borrower will not make
         that payment in full, the Administrative Agent may assume that the
         Borrower has made the full payment due and the Administrative Agent
         may, in reliance upon that assumption, cause to be distributed to each
         Lender on that date the amount then due to each Lender. If and to the
         extent the Borrower does not make the full payment due to the
         Administrative Agent, each Lender shall repay to the Administrative
         Agent on demand the amount distributed to that Lender by the
         Administrative Agent together with interest for each day from the date
         that Lender received payment from the Administrative Agent until the
         date that Lender repays the Administrative Agent (unless such repayment
         is made on the same day as such distribution), at an interest rate
         equal to the Federal-Funds Rate.

         3.2 Interest and Principal Payments.

                  (a) Interest. Accrued interest on each LIBOR Borrowing is due
         and payable on the last day of its respective Interest Period. If any
         Interest Period for a LIBOR Borrowing is greater than three months,
         then accrued interest is also due and payable on the date three months
         after the commencement of the Interest Period. Until converted to a
         LIBOR Borrowing under SECTION 3.10(b), accrued interest on each
         Base-Rate Borrowing is due and payable on the fifth (5th) day of each
         January, April, July, and October, commencing on the first of those
         dates that follows the Closing Date, and on the Maturity Date.

                  (b) Principal. The Term Loans are due and payable on the
         Maturity Date.

                  (c) Optional Prepayments. Before the occurrence of the
         Maturity Date, the Borrower may prepay, without penalty and in whole or
         in part, the Term Loans, so long as (i) each voluntary partial
         prepayment must be in a principal amount not less than (A) $500,000 or
         a greater integral multiple of $100,000 if a prepayment of Base-Rate
         Borrowings, or (B) $5,000,000 or a greater integral multiple of
         $1,000,000 if a prepayment of LIBOR Borrowings, (ii) the Borrower shall
         give prior written and irrevocable notice to the Administrative Agent
         (A) at least three (3) Business Days before any prepayment of a LIBOR
         Borrowing or (B) at least one Business Day before any prepayment of a
         Base-Rate Borrowing, and (iii) the Borrower shall pay any related
         Funding Loss upon demand. Conversions under SECTION 3.10 are not
         prepayments.

                  (d) Mandatory Prepayments.

                           (i) If any Stock (including Stock issued pursuant to
                  a Subject Securities Issuance or a Permitted IPO, but
                  excluding Net Cash Proceeds of any issuance of Stock in
                  connection with employee and director stock option plans
                  granted in the ordinary course of business) or Debt shall be
                  issued or incurred by any Company (other than Permitted Debt
                  (other than Debt permitted under

                                       21
<PAGE>   29

                  CLAUSES (h) and (i) of the definition thereof)), an amount
                  equal to 100% of the Net Cash Proceeds thereof shall be
                  applied within five (5) Business Days of the receipt of such
                  Net Cash Proceeds toward the prepayment of the Term Loans.

                           (ii) If on any date any Company shall receive Net
                  Cash Proceeds from any Asset Sale then such Net Cash Proceeds
                  shall be applied within five (5) Business Days of the receipt
                  of such Net Cash Proceeds toward the prepayment of the Term
                  Loans, provided that (A) no such prepayment shall be required
                  until the aggregate Net Cash Proceeds of all such Asset Sales
                  subsequent to the Closing Date exceed $10,000,000 and then
                  only to the extent such aggregate Net Cash Proceeds exceed
                  $10,000,000 and (B) to the extent such Net Cash Proceeds are
                  Net Cash Proceeds of a casualty or condemnation event, the
                  relevant Company shall be permitted to reinvest such Net Cash
                  Proceeds to replace or repair the assets which were the
                  subject of such casualty or condemnation event within 270 days
                  after the occurrence thereof (such Company shall deliver a
                  notice to the Administrative Agent prior to the required
                  prepayment date of its intent to so reinvest such Net Cash
                  Proceeds and, to the extent not so reinvested during such
                  period, the portion of the Net Cash Proceeds which have not
                  been so reinvested shall be applied to prepay the Term Loans
                  on the last day of such period).

                           (iii) For purposes of this Section, the Net Cash
                  Proceeds of an Accounts Receivable Financing shall be treated
                  as Net Cash Proceeds of the incurrence of Debt by a Company.

         3.3 Interest Options. Borrowings shall bear interest at an annual rate
equal to the lesser of (i) or (ii): (i) the Base Rate or LIBOR, in each case
plus the Applicable Margin (in each case as designated or deemed designated by
the Borrower) or (ii) the Maximum Rate. Each change in the Base Rate and Maximum
Rate is effective, without notice to the Borrower or any other Person, upon the
effective date of change.

         3.4 Quotation of Rates. The Borrower may call the Administrative Agent
before delivering a Borrowing Request to receive an indication of the interest
rates then in effect, but the indicated rates do not bind the Administrative
Agent or the Lenders or affect the interest rate that is actually in effect when
the Borrower makes a Borrowing Request.

         3.5 Default Rate. If permitted by Law, all past-due Term Loans and
past-due interest accruing thereon bears interest from the date due (stated or
by acceleration) at the Default Rate until paid, regardless whether payment is
made before or after entry of a judgment.

         3.6 Interest Recapture. If the designated interest rate applicable to
any Borrowing exceeds the Maximum Rate, the interest rate on that Borrowing is
limited to the Maximum Rate, but any subsequent reductions in the designated
rate shall not reduce the interest rate thereon below the Maximum Rate until the
total amount of accrued interest equals the amount of interest that would have
accrued if that designated rate had always been in effect. If at maturity
(stated or by acceleration), or at final payment of the Term Loans, the total
interest paid or accrued is less than the interest that would have accrued if
the designated rates had always been in effect, then, at that time and to the
extent permitted by Law, the Borrower shall pay an amount equal to

                                       22
<PAGE>   30

the difference between (a) the lesser of the amount of interest that would have
accrued if the designated rates had always been in effect and the amount of
interest that would have accrued if the Maximum Rate had always been in effect,
and (b) the amount of interest actually paid or accrued on the Term Loans.

         3.7 Interest Calculations. Interest will be calculated on the basis of
actual number of days (including the first day but excluding the last day)
elapsed but computed as if each calendar year consisted of 360 days (unless the
calculation would result in an interest rate greater than the Maximum Rate, or
in the case of interest on Base-Rate Borrowings in which event interest will be
calculated on the basis of a year of 365 or 366 days, as the case may be). All
interest rate determinations and calculations by the Administrative Agent are
conclusive and binding absent manifest error.

         3.8 Maximum Rate. Regardless of any provision contained in any Loan
Document, no Credit Party is entitled to contract for, charge, take, reserve,
receive, or apply, as interest on all or any part of the Obligation, any amount
in excess of the Maximum Rate, and, if any Credit Party ever does so, then any
excess shall be treated as a partial prepayment of principal and any remaining
excess shall be refunded to the Borrower. In determining if the interest paid or
payable exceeds the Maximum Rate, the Borrower and the Credit Parties shall, to
the maximum extent permitted under applicable Law, (a) treat all Borrowings as
but a single extension of credit (and the Credit Parties and the Borrower agree
that is the case and that provision in this Agreement for multiple Borrowings is
for convenience only), (b) characterize any nonprincipal payment as an expense,
fee, or premium rather than as interest, (c) exclude voluntary prepayments and
their effects, and (d) amortize, prorate, allocate, and spread the total amount
of interest throughout the entire contemplated term of the Obligation. However,
if the Obligation is paid in full before the end of its full contemplated term,
and if the interest received for its actual period of existence exceeds the
Maximum Amount, the Credit Parties shall refund any excess (and Credit Parties
may not, to the extent permitted by Law, be subject to any penalties provided by
any Laws for contracting for, charging, taking, reserving, or receiving interest
in excess of the Maximum Amount). If the Laws of the State of Texas are
applicable for purposes of determining the "Maximum Rate" or the "Maximum
Amount," then those terms mean the "weekly ceiling" from time to time in effect
under Texas Finance Code Section 303.305. The Borrower agrees that Chapter 346
of the Texas Finance Code, as amended (which regulates certain revolving credit
loan accounts and revolving triparty accounts), does not apply to the
Obligation.

         3.9 Interest Periods. When the Borrower requests any LIBOR Borrowing,
the Borrower may elect the applicable interest period (each an "INTEREST
PERIOD"), which may be, at the Borrower's option, one, two, three, or six months
for LIBOR Borrowings, subject to SECTION 14.1 and the following conditions: (a)
the initial Interest Period for a LIBOR Borrowing commences on the applicable
Borrowing Date or conversion date, and each subsequent Interest Period
applicable to any Borrowing commences on the day when the next preceding
applicable Interest Period expires; (b) if any Interest Period for a LIBOR
Borrowing begins on a day for which no numerically corresponding Business Day in
the calendar month at the end of the Interest Period exists, then the Interest
Period ends on the last Business Day of that calendar month; (c) if the Borrower
is required to pay any portion of a LIBOR Borrowing before the end of its
Interest Period in order to comply with the payment provisions of the Loan
Documents, the

                                       23
<PAGE>   31

Borrower shall also pay any related Funding Loss; and (d) no more than ten
Interest Periods may be in effect at one time.

         3.10 Conversions. Subject to the dollar limits of SECTION 2.1(a) and
provided that the Borrower may not convert to or select a new Interest Period
for a LIBOR Borrowing at any time when a Default or Potential Default exists,
the Borrower may (a) convert a LIBOR Borrowing on the last day of the applicable
Interest Period to a Base-Rate Borrowing, (b) convert a Base-Rate Borrowing at
any time to a LIBOR Borrowing, and (c) elect a new Interest Period for a LIBOR
Borrowing. That election may be made by telephonic request to the Administrative
Agent no later than 12:00 p.m. noon on the third Business Day before the
conversion date or the last day of the Interest Period, as the case may be (for
conversion to a LIBOR Borrowing or election of a new Interest Period), and no
later than 12:00 p.m. noon on the last day of the Interest Period (for
conversion to a Base-Rate Borrowing). The Borrower shall provide a Conversion
Notice to the Administrative Agent no later than two (2) days after the date of
the conversion or election. Absent the Borrower's telephonic request for
conversion or election of a new Interest Period or if a Default or Potential
Default exists, then, a LIBOR Borrowing shall be deemed converted to a Base-Rate
Borrowing effective when the applicable Interest Period expires.

         3.11 Order of Application.

                  (a) No Default. Except as provided in SECTION 3.11(b), any
         payment shall be applied to the Obligation, except as otherwise
         specifically provided in the Loan Documents, in the order and manner as
         the Borrower directs.

                  (b) Default. If the maturity of the Term Loans is accelerated
         pursuant to SECTION 11 or if the Borrower fails to give direction, any
         payment (including proceeds from the exercise of any Rights) shall be
         applied in the following order: (i) to all fees and expenses for which
         the Credit Parties have not been paid or reimbursed in accordance with
         the Loan Documents (and if such payment is less than all unpaid or
         unreimbursed fees and expenses, then the payment shall be paid against
         unpaid and unreimbursed fees and expenses in the order of incurrence or
         due date); (ii) to accrued interest on the Term Loans; and (iii) to the
         Term Loans and (iv) to the remaining Obligation in the order and manner
         Required Lenders deem appropriate.

                  (c) Pro Rata. Each payment or prepayment (other than pursuant
         to CLAUSE (b)(iv), which payments shall be made pro rata) shall be
         distributed to each Lender in accordance with its Pro Rata Part of that
         payment or prepayment.

         3.12 Sharing of Payments, Etc. If any Lender obtains any payment or
prepayment with respect to the Obligation (whether voluntary, involuntary, or
otherwise, including, without limitation, as a result of exercising its Rights
under SECTION 3.13) that exceeds the part of that payment or prepayment that it
is then entitled to receive under the Loan Documents, then that Lender shall
purchase from the other Lenders participations that will cause the purchasing
Lender to share the excess payment or prepayment ratably with each other Lender.
If all or any portion of any excess payment or prepayment is subsequently
recovered from the purchasing Lender, then the purchase shall be rescinded and
the purchase price restored to the extent of the recovery. The Borrower agrees
that any Lender purchasing a participation from another Lender

                                       24
<PAGE>   32

under this section may, to the fullest extent permitted by Law, exercise all of
its Rights of payment (including the Right of offset) with respect to that
participation as fully as if that Lender were the direct creditor of the
Borrower in the amount of that participation.

         3.13 Offset. If a Default exists, each Lender is entitled to exercise
(for the benefit of all Lenders in accordance with SECTION 3.12) the Rights of
offset and banker's lien against each and every account (excluding Settlement
Aggregation Accounts) and other property, or any interest therein, that any
Company may now or hereafter have with, or which is now or hereafter in the
possession of, that Lender to the extent of the full amount of the Obligation
owed (directly or participated) to it.

         3.14 Booking Borrowings. To the extent permitted by Law, any Lender may
make, carry, or transfer its Borrowings at, to, or for the account of any of its
branch offices or the office or branch of any of its Affiliates. However, no
Affiliate or branch is entitled to receive any greater payment under SECTION
3.16 than the transferor Lender would have been entitled to receive with respect
to those Borrowings, and a transfer may not be made if, as a direct result of
it, SECTION 3.15 or 3.17 would apply to any of the Obligation. If any of the
conditions of SECTIONS 3.16 or 3.17 ever apply to a Lender, that Lender shall,
to the extent possible, carry or transfer its Borrowings at, to, or for the
account of any of its branch offices or the office or branch of any of its
Affiliates so long as the transfer is consistent with the other provisions of
this section, does not create any burden or adverse circumstance for that Lender
that would not otherwise exist, and eliminates or ameliorates the conditions of
SECTIONS 3.16 or 3.17 as applicable.

         3.15 Basis Unavailable or Inadequate for LIBOR. If, on or before any
date when LIBOR is to be determined for a Borrowing, the Administrative Agent
reasonably determines that the basis for determining the applicable rate is not
available or any Lender reasonably determines that the resulting rate does not
accurately reflect the cost to that Lender of making or converting Borrowings at
that rate for the applicable Interest Period, then the Administrative Agent
shall promptly notify the Borrower and the Lenders of that determination (which
is conclusive and binding on the Borrower absent manifest error) and the
applicable Borrowing shall be a Base-Rate Borrowing. Until the Administrative
Agent notifies the Borrower that those circumstances no longer exist, the
Lenders' commitments under this Agreement to make, or to convert to, LIBOR
Borrowings, as the case may be, are suspended.

         3.16 Additional Costs. Each Lender severally and not jointly agrees to
notify the Administrative Agent, the other Credit Parties, and the Borrower
within 180 days after it has actual knowledge that any circumstances exist that
would give rise to any payment obligation by the Borrower under CLAUSES (a)
through (c) below. Although no Lender shall have any liability to any other
Credit Party, or any Company for its failure to give that notice, the Borrower
is not obligated to pay any amounts under those clauses that arise, accrue, or
are imposed more than 180 days before that notice to the extent it is applicable
to those amounts. Any Lender demanding payment of any additional costs under
this section must generally be making similar demand for similar additional
costs under credit agreements to which it is party that contain similar
provisions to this section.

                                       25
<PAGE>   33

                  (a) Reserves. With respect to any LIBOR Borrowing (i) if any
         change in any present Law, any change in the interpretation or
         application of any present Law, or any future Law imposes, modifies, or
         deems applicable (or if compliance by any Lender with any requirement
         of any Tribunal results in) any requirement that any reserves
         (including, without limitation, any marginal, emergency, supplemental,
         or special reserves) be maintained (other than any reserve included in
         the Reserve Requirement), and if (ii) those reserves reduce any sums
         receivable by that Lender under this Agreement or increase the costs
         incurred by that Lender in advancing or maintaining any portion of any
         LIBOR Borrowing, then (iii) that Lender (through the Administrative
         Agent) shall deliver to the Borrower a certificate setting forth in
         reasonable detail the calculation of the amount necessary to compensate
         it for its reduction or increase (which certificate is conclusive and
         binding absent manifest error), and (iv) the Borrower shall pay that
         amount to that Lender within five (5) Business Days after demand. The
         provisions of and undertakings and indemnification in this CLAUSE (a)
         survive the satisfaction and payment of the Obligation and termination
         of this Agreement.

                  (b) Capital Adequacy. With respect to any Borrowing, if any
         change in any present Law, any change in the interpretation or
         application of any present Law, or any future Law regarding capital
         adequacy, or if compliance by any Lender with any request, directive,
         or requirement imposed in the future by any Tribunal regarding capital
         adequacy, or if any change in its written policies or in the risk
         category of this transaction, in any of the foregoing events or
         circumstances, reduces the rate of return on its capital as a
         consequence of its obligations under this Agreement to a level below
         that which it otherwise could have achieved (taking into consideration
         its policies with respect to capital adequacy) by an amount deemed by
         it to be material (and it may, in determining the amount, utilize
         reasonable assumptions and allocations of costs and expenses and use
         any reasonable averaging or attribution method), then (unless the
         effect is already reflected in the rate of interest then applicable
         under this Agreement) the Administrative Agent or that Lender (through
         the Administrative Agent) shall notify the Borrower and deliver to the
         Borrower a certificate setting forth in reasonable detail the
         calculation of the amount necessary to compensate it (which certificate
         is conclusive and binding absent manifest error), and the Borrower
         shall pay that amount to the Administrative Agent or that Lender within
         five (5) Business Days after demand. Notwithstanding the foregoing
         sentence, the Borrower shall not be obligated to pay such amount unless
         notice thereof is given within ninety (90) Business Days after any such
         Lender actually incurs such reduction in its return. The Lenders are
         not aware of any event which would so reduce their rate of return as of
         the date hereof. If any such event giving rights to a demand by any
         Lender for compensation under this SECTION 3.16(b) occurs specifically
         with respect to such Lender, and generally with respect to national
         banks similarly situated for loans of the same classification, the
         Borrower may elect to prepay the Obligation in full within one hundred
         twenty (120) days after receipt of the above-described certificate from
         the Administrative Agent by giving written notice to the Administrative
         Agent or that Lender through the Administrative Agent) of such election
         not more than five (5) Business Days after receipt of such certificate
         from the Administrative Agent; provided, however, that if the Borrower
         does not prepay the Obligation within such 120-day period despite
         having given such notice, this Agreement shall remain in full force and
         effect as if such notice was never given. The provisions of

                                       26
<PAGE>   34

         and undertakings and indemnification in this CLAUSE (b) shall survive
         the satisfaction and payment of the Obligation and termination of this
         Agreement.

                  (c) HLT. Neither the Borrower nor any Lender is aware of any
         circumstances which would result in classifying this transaction as a
         "highly leveraged transaction" as of the Closing Date under "HLT"
         guidelines promulgated by any Tribunal (including, without limitation,
         the Office of the Comptroller of the Currency). If any Tribunal or any
         Lender (as it interprets "HLT guidelines" promulgated by any Tribunal)
         classifies this transaction as a "highly leveraged transaction," such
         Lender (through the Administrative Agent) shall promptly notify the
         Borrower of such classification and the applicable interest rate margin
         in all contexts shall be increased by 1% as of the date of such notice.

                  (d) Taxes. Subject to SECTION 3.19, any Taxes payable by any
         Credit Party or ruled (by a Tribunal) payable by a Credit Party in
         respect of this Agreement or any other Loan Document shall, if
         permitted by Law, be paid by the Borrower, together with interest and
         penalties, if any, except for Taxes payable on or measured by the
         overall net income of that Credit Party (or that Credit Party, as the
         case may be, together with any other Person with whom that Credit Party
         files a consolidated, combined, unitary, or similar Tax return) and
         except for interest and penalties incurred as a result of the gross
         negligence or willful misconduct of any Credit Party. The Credit Party
         (through the Administrative Agent) shall notify the Borrower and
         deliver to the Borrower a certificate setting forth in reasonable
         detail the calculation of the amount of payable Taxes, which
         certificate is conclusive and binding (absent manifest error), and the
         Borrower shall pay that amount to the Administrative Agent for its
         account or the account of that Credit Party, as the case may be within
         five (5) Business Days after demand. If that Credit Party subsequently
         receives a refund of the Taxes paid to it by the Borrower, then the
         recipient shall promptly pay the refund to the Borrower.

         3.17 Change In Laws. If any Law makes it unlawful for any Lender to
make or maintain LIBOR Borrowings, then that Lender shall promptly notify the
Borrower and the Administrative Agent, and (a) as to undisbursed funds, that
requested Borrowing shall be made as a Base-Rate Borrowing, and (b) as to any
outstanding Borrowing (i) if maintaining the Borrowing until the last day of the
applicable Interest Period is unlawful, the Borrowing shall be converted to a
Base-Rate Borrowing as of the date of notice, in which event the Borrower will
be required to pay any related Funding Loss, or (ii) if not prohibited by Law,
the Borrowing shall be converted to a Base-Rate Borrowing as of the last day of
the applicable Interest Period, or (iii) if any conversion will not resolve the
unlawfulness, the Borrower shall promptly prepay the Borrowing, without penalty
but with related Funding Loss.

         3.18 FUNDING LOSS. THE BORROWER SHALL INDEMNIFY EACH LENDER AGAINST,
AND PAY TO IT UPON DEMAND, ANY FUNDING LOSS OF THAT LENDER. WHEN ANY LENDER
DEMANDS THAT THE BORROWER PAY ANY FUNDING LOSS, THAT LENDER SHALL DELIVER TO THE

         3.19 Taxes.

                  (a) Any and all payments by the Borrower to or for the account
         of any Credit Party hereunder or under any other Loan Document shall be
         made free and clear of and without deduction for any and all present or
         future Taxes, excluding, in the case of each Credit Party, Taxes based
         on or measured by its income, and franchise taxes imposed on it, by the
         jurisdiction under the Laws of which such Credit Party (or its
         Applicable Lending Office) is organized or any political subdivision
         thereof (such income and franchise Taxes being "EXCLUDED TAXES").

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

                  (c) The Borrower agrees to indemnify each Credit Party for the
         full amount of Taxes (other than Excluded Taxes) and Other Taxes
         (including any Taxes or Other Taxes imposed or asserted by any
         jurisdiction on amounts payable under this SECTION 3.19) paid by such
         Credit Party (as the case may be) and any liability (including
         penalties, interest, and expenses) arising therefrom or with respect
         thereto.

                  (d) Each Lender organized under the Laws of a jurisdiction
         outside the United States, on or prior to the date of its execution and
         delivery of this Agreement in the case of each Lender listed on the
         signature pages hereof and on or prior to the date on which it becomes
         a Lender in the case of each other Lender, and from time to time
         thereafter if requested in writing by the Borrower or the
         Administrative Agent (but only so long as such Lender remains lawfully
         able to do so), shall provide the Borrower and the Administrative Agent
         with (i) Internal Revenue Service Form W-8 BEN or Form W-8 ECI, as
         appropriate, or any successor form prescribed by the Internal Revenue
         Service, certifying that such Lender is entitled to benefits under an
         income tax treaty to which the United States is a party which reduces
         the rate of withholding tax on payments of interest or certifying that
         the income receivable pursuant to this Agreement is effectively
         connected with the conduct of a trade or business in the United States,
         (ii) Internal Revenue Service Form W-8 BEN or Form W-8 ECI, as
         appropriate, or any successor form prescribed by the Internal Revenue
         Service, and (iii) any other form or certificate required by any taxing
         authority (including any certificate required by Sections 871(h) and
         881(c) of the Code), certifying that such Lender is entitled to an
         exemption from or a reduced rate of tax on payments pursuant to this
         Agreement or any of the other Loan Documents.

                  (e) For any period with respect to which a Lender has failed
         to provide the Borrower and the Administrative Agent with the
         appropriate form pursuant to SECTION 3.19 (unless such failure is due
         to a change in any Laws occurring subsequent to the date on which a
         form originally was required to be provided), such Lender shall not be
         entitled to indemnification under SECTION 3.19(c) with respect to Taxes
         imposed by the United States; provided, however, that should a Lender,
         which is otherwise exempt from or

                                       28
<PAGE>   36

         subject to a reduced rate of withholding tax, become subject to Taxes
         (other than Excluded Taxes) because of its failure to deliver a form
         required hereunder, the Borrower shall take such steps as such Lender
         shall reasonably request to assist such Lender to recover such Taxes.

                  (f) If the Borrower is required to pay additional amounts to
         or for the account of any Lender pursuant to this SECTION 3.19, then
         such Lender will agree to use reasonable efforts to change the
         jurisdiction of its applicable lending office so as to eliminate or
         reduce any such additional payment which may thereafter accrue if such
         change, in the judgment of such Lender, is not otherwise
         disadvantageous to such Lender.

                  (g) Within thirty (30) days after the date of any payment of
         Taxes or Other Taxes, the Borrower will provide to the Administrative
         Agent (upon its request) a copy of the reports required by the
         applicable taxing authority and accompanying such payment.

                  (h) Without prejudice to the survival of any other agreement
         of the Borrower hereunder, the agreements and obligations of the
         Borrower contained in this SECTION 3.19 shall survive the termination
         of the Commitments and the payment in full of the Term Loans for the
         applicable period of the statute of limitations.

this Agreement:

                  (a) the Borrower shall cause all of its present and future
         direct and indirect Domestic Subsidiaries for which at least 70% of
         each of their Voting Stock is owned of record or beneficially by a
         Company, whether now existing or in the future formed or acquired, to
         unconditionally guarantee in favor of the Credit Parties the full
         payment and performance of the Obligation pursuant to the Subsidiary

                           Total Net Worth, or (B) exceeds, with respect to
                           Non-Guaranteeing Subsidiaries in the aggregate, (10%)
                           of Total Net Worth, or

                           (ii) the Adjusted EBITDA of Non-Guaranteeing

                           Adjusted EBITDA of the Companies;

                  then, the Borrower, within fifteen (15) days, shall either (x)

         Guarantor (or a Foreign Subsidiary the Stock of which is subject to a
         Foreign Stock Pledge) is transferred, sold or assigned to a Person who
         is not an Affiliate, or (ii) a Subsidiary Guarantor (or a Foreign
         Subsidiary the Stock of which is subject to a Foreign Stock Pledge) is
         the subject of a Permitted IPO then the Administrative Agent shall,
         provided no Default or Potential Default is then in existence, release
         the Subsidiary Guaranty with respect to such Subsidiary Guarantor, or
         the Foreign Stock Pledge with respect to such Foreign Subsidiary.

                  (d) The Borrower shall not cause any Subsidiary to guarantee
         the Existing Credit Agreement, or create (or cause to be created) any
         Lien to secure the Existing Credit Agreement, without contemporaneously
         causing such Subsidiary to deliver a corresponding Subsidiary Guaranty,
         or creating (or causing to be created) a corresponding security
         interest, in favor of the Lenders (any such security interest to be
         shared equally and ratably in accordance with the Intercreditor
         Agreement).

         5.2 Foreign Stock Pledge. Any Foreign Stock Pledge delivered, or caused

         important activities, in the business of extending credit for the
         purpose of purchasing or carrying any "margin stock" within the meaning

of the threat of, any Litigation that is reasonably likely to be determined

         applicable Environmental Law, other than such violations which would
         not constitute a Material Adverse Event.

                  (b) No Company has received notice from any Tribunal that it

<PAGE>   42

         Environmental Liability, which actual or potential Environmental
         Liability in either case constitutes a Material Adverse Event.

                  (c) No Company has received notice from any Tribunal that any
         Real Property is affected by, and no Company has knowledge that any
         Real Property is affected by, any Release of any Hazardous Substance
         which constitutes a Material Adverse Event.

         7.11 Employee Plans. Except as disclosed on SCHEDULE 7.11, (a) no

engaged in any "prohibited transaction" (as defined in Section 406 of ERISA or
Section 4975 of the Code), (e) no "reportable event" (as defined in Section 4043
of ERISA) has occurred excluding events for which the notice requirement is
waived under applicable PBGC regulations, (f) neither the Borrower nor any ERISA

of all benefit liabilities within the meaning of Title IV of ERISA under each

         Subordinated Notes due March 15, 2005 (the "4% Notes"), and
         notwithstanding anything to the contrary in this Agreement, the
         Borrower may elect to induce the conversion of such 4% Notes by either

         Notes by adjusting the Conversion Price (as defined in the related
         Indenture dated as of March 20, 1998 (such Indenture, as in effect on
         the date hereof, the "4% Indenture")), or (ii) issuing a notice of
         redemption under the 4% Indenture (and repurchasing any such 4% Notes
         which are not converted prior to the date of redemption), so long as,
         as of the date of issuance of such notice of redemption, (a) the

         by (y) the then applicable "Conversion Rate" (as defined in the 4%
         Indenture), (b) the closing price of the Borrower's common stock on the
         New York Stock Exchange on the business day immediately preceding the
         date of issuance of such notice of redemption is at least equal to 125%
         of the amount which is equal to (x) 1,000 divided by (y) the then
         applicable Conversion Rate and (c) either (x) the sum of (I) the
         Companies' consolidated cash on hand reflected in the balance sheet of
         the Borrower and its consolidated Subsidiaries as of such date plus
         (II) the amount available to be borrowed under the Revolving Facility
         as of such date is at least equal to the aggregate "Redemption Price"
         (and the Borrower shall maintain a sufficient amount of such liquidity
         during the period up to and including the redemption date to finance
         its reasonably anticipated liability in respect of such Redemption
         Price on such redemption date) (as defined in the 4% Indenture) for all
         such 4% Notes as of such date, or (y) the Borrower shall have arranged
         financing to pay the Redemption Price on terms and conditions
         satisfactory to the Administrative Agent.

         9.17 Changes Relating to Subordinated Notes. The Borrower may not agree

indenture or agreement in connection therewith) if the effect of such change or
amendment is to: (a) increase the interest rate on the Subordinated Notes; (b)
change the dates upon which payments of principal or interest are due on the
Subordinated Notes other than to extend such dates; (c) change any default or
event of default or covenant other than to delete or make less restrictive any
default or covenant provision therein, or add any covenant with respect to the
Subordinated Notes; (d) change the redemption or prepayment provisions of such
the Subordinated Notes other than to extend the dates therefor or to reduce the
premiums payable in connection therewith; (e) grant any security, collateral or
guaranty to secure payment of the Subordinated Notes; or (f) change or amend any
other term if such change or amendment would materially increase the obligations
of the obligor or confer additional material rights to the holder of the
Subordinated Notes in a manner adverse to the Borrower, the Administrative
Agent, or any Lender.

performed, the Borrower covenants and agrees with the Administrative Agent and

         Voting Stock (or similar voting interests) of such Subsidiaries
         sufficient to constitute control of such Subsidiary, or (ii) such
         Subsidiaries incur Debt to any Person other than Permitted Debt.

         11.9 Change of Control of the Borrower. The individuals who, as of the
date of this Agreement, constitute the members of the Borrower's board of
directors (for purposes of this SECTION 11.9, the "INCUMBENT BOARD") do not

board, shall thereafter be deemed to be a member of the incumbent board.

         11.10 Other Funded Debt. In respect of any Debt (other than the
Obligation, Debt arising under the Existing Credit Agreement and Debt arising
under the Subordinated Notes) individually or collectively of at least
$10,000,000 (a) any default or other event or condition occurs or exists (other
than a mandatory prepayment as a result of disposition of assets if permitted by
the Loan Documents) beyond the applicable grace or cure period (and solely with
respect to the Debt set forth in ITEMS 2 and 4 of SCHEDULE 9.1, such default or
other event or condition continues for twenty (20) Business Days beyond such
grace or cure period) the effect of which is to cause or to permit any holder of
that Funded Debt to cause, whether or not it elects to cause, any of that Funded
Debt to become due before its stated maturity or regularly scheduled payment
dates, or (b) any of that Debt is declared to be due and payable or required to
be prepaid by any Company before its stated maturity (and solely with respect to

                                       51
<PAGE>   59

Business Days after such guaranty is called). Notwithstanding the foregoing
sentence, it shall not be a Default if (y) either (i) the validity or amount of
such accelerated Debt is being contested in good faith by lawful proceedings
diligently conducted, or (ii) a nonappealable judgment has been entered against
any Company with respect to such Debt, and such judgment is satisfied within
ninety (90) days after it is entered, and (z) a reserve or other provision
required by GAAP has been made.

         11.11 SEC Reporting Requirements. The Borrower fails to comply with any
applicable reporting requirements of the 1934 Act, for which the failure to
report would constitute a Material Adverse Event.

         11.12 Validity and Enforceability. Once executed, this Agreement
(including, but not limited to, the Subsidiary Guaranty), any Note, the
Intercreditor Agreement, or any Security Document ceases to be in full force and

validity or enforceability is contested in writing by any Company party to it or
any Company party to it denies in writing that it has any further liability or
obligations under it except in accordance with that document's express
provisions or as the appropriate parties under SECTION 14.8 below may otherwise
agree in writing.

         11.13 Material Agreements. The occurrence of a default under any other
Material Agreement (other than any Material Agreement described in SECTION
11.15) which results in the acceleration of payment of any amounts payable by
any Company in excess of $10,000,000. Notwithstanding the foregoing sentence, it
shall not be a default if (y) either (i) the validity or amount of such
accelerated payment is being contested in good faith by lawful proceedings
diligently conducted, or (ii) a nonappealable judgment has been entered against
any Company with respect to Material Agreement Debt, and such judgment is
satisfied within ninety (90) days after it is entered, and (z) a reserve or
other provision required by GAAP has been made.

         11.14 Material Adverse Event. The occurrence of any Material Adverse
Event, and the situation giving rise thereto is not corrected to the
satisfaction of the Administrative Agent and the Lenders within twenty (20) days
after notice thereof from the Administrative Agent to the Borrower.

                  (a) a "Reportable Event" or "Reportable Events," or a failure
         to make a required installment or other payment (within the meaning of
         Section 412(n)(1)

                                       52

         of the Code), shall have occurred with respect to any Employee Plan or

         PBGC or to an Employee Plan; or

                  (b) the Borrower or any ERISA Affiliate has provided to any
         affected party a sixty (60) day notice of intent to terminate an

         result of such termination will exceed $1,000,000.00; or

                  (c) a trustee shall be appointed by a United States district
         court to administer any such Employee Plan; or

                  (d) the PBGC shall institute proceedings (including giving

         not have reasonable grounds for contesting such withdrawal liability or
         is not contesting such withdrawal liability in a timely and appropriate
         manner and (iii) the amount of such withdrawal liability specified in
         such notice, when aggregated with all other amounts required to be paid
         to Multiemployer Plans in connection with withdrawal liabilities
         (determined as of the date or dates of such notification), exceeds
         $1,000,000.00; or

                  (f) the Borrower or any ERISA Affiliate shall have been
         notified by the sponsor of a Multiemployer Plan that such Multiemployer
         Plan is in reorganization or is being terminated, within the meaning of
         Title IV of ERISA, if solely as a result of such reorganization or

         ERISA Affiliates to all Multiemployer Plans that are then in
         reorganization or have been or are being terminated have been or will
         be increased over the amounts required to be contributed to such
         Multiemployer Plans for their most recently completed plan years by an
         amount exceeding $1,000,000.00.

SECTION 12: RIGHTS AND REMEDIES.

         12.1 Remedies Upon Default.

                  (a) Debtor Relief. If a Default exists under SECTION 11.3, the
         commitment to extend credit under this Agreement automatically
         terminates, and the entire unpaid balance of the Obligation
         automatically becomes due and payable without any action of any kind
         whatsoever.

                  (b) Other Defaults. If any Default exists, subject to the
         terms of SECTION 13.5(b), the Administrative Agent may (with the
         consent of, and must, upon the request of, the Required Lenders), do
         any one or more of the following: (i) if the maturity of the Obligation
         has not already been accelerated under SECTION 12.1(a), declare the
         entire unpaid balance of all or any part of the Obligation immediately
         due and payable, whereupon it is due and payable; (ii) terminate the
         commitments of Lenders to

                                       53
<PAGE>   61

         extend credit under this Agreement; (iii) reduce any claim to judgment;
         and (iv) exercise any and all other legal or equitable Rights afforded
         by the Loan Documents, by applicable Laws, or in equity.

                  (c) Offset. If a Default exists, to the extent permitted by
         applicable Law, each Lender may exercise the Rights of offset and
         banker's lien against each and every account (excluding Settlement
         Aggregation Accounts) and other property, or any interest therein,
         which any Company may now or hereafter have with, or which is now or
         hereafter in the possession of, that Lender to the extent of the full
         amount of the Obligation owed to that Lender.

         12.2 Company Waivers. To the extent permitted by Law, each Obligor
waives presentment and demand for payment, protest, notice of intention to
accelerate, notice of acceleration, and notice of protest and nonpayment, and
agrees that its liability with respect to all or any part of the Obligation is
not affected by any renewal or extension in the time of payment of all or any
part of the Obligation, by any indulgence, or by any release or change in any
security for the payment of all or any part of the Obligation.

         12.3 Performance by the Administrative Agent. If any Company's
covenant, duty, or agreement is not performed in accordance with the terms of
the Loan Documents, Administrative Agent may, while a Default exists, at its
option (but subject to the approval of the Required Lenders), perform or attempt
to perform that covenant, duty, or agreement on behalf of that Company (and any
amount expended by the Administrative Agent in its performance or attempted
performance is payable by the Obligors, jointly and severally, to the
Administrative Agent on demand, becomes part of the Obligation, and bears
interest at the Default Rate from the date of the Administrative Agent's
expenditure until paid). However, the Administrative Agent does not assume and
shall never have, except by its express written consent, any liability or
responsibility for the performance of any Company's covenants, duties, or
agreements.

         12.4 Not in Control. Nothing in any Loan Documents gives or may be
deemed to give to any Credit Party the Right to exercise control over any
Company's Real Property, other assets, affairs, or management or to preclude or
interfere with any Company's compliance with any Law or require any act or
omission by any Company that may be harmful to Persons or property. Any
"Material Adverse Event" or other materiality or substantiality qualifier of any
representation, warranty, covenant, agreement, or other provision of any Loan
Document is included for credit documentation purposes only and does not imply
or be deemed to mean that any Credit Party acquiesces in any non-compliance by
any Company with any Law, document, or otherwise or does not expect the
Companies to promptly, diligently, and continuously carry out all appropriate
removal, remediation, compliance, closure, or other activities required or
appropriate in accordance with all Environmental Laws. The Credit Parties'
powers are limited to the Rights provided in the Loan Documents. All of those
Rights exist solely, and may be exercised in any manner calculated by the
Administrative Agent or the Lenders in their respective good faith business
judgment, to preserve and protect collateral, Lender Liens and to assure payment
and performance of the Obligation.

         12.5 Course of Dealing. The acceptance by any Credit Party of any
partial payment on Obligation is not a waiver of any Default then existing. No
waiver by the Administrative Agent,

                                       54
<PAGE>   62

Required Lenders, or any other Credit Party of any Default is a waiver of any
other then-existing or subsequent Default. No delay or omission by the
Administrative Agent, the Required Lenders, or any other Credit Party in
exercising any Right under the Loan Documents impairs that Right or is a waiver
thereof or any acquiescence therein, nor will any single or partial exercise of
any Right preclude other or further exercise thereof or the exercise of any
other Right under the Loan Documents or otherwise.

         12.6 Cumulative Rights. All Rights available to any Credit Party under
the Loan Documents are cumulative of and in addition to all other Rights granted
to any Credit Party at law or in equity, whether or not the Obligation is due
and payable and whether or not any Credit Party has instituted any suit for
collection, foreclosure, or other action in connection with the Loan Documents.

         12.7 Application of Proceeds. Any and all proceeds ever received by any
Credit Party from the exercise of any Rights pertaining to the Obligation shall
be applied to the Obligation according to SECTION 3, except to the extent
otherwise provided in the Intercreditor Agreement.

         12.8 Certain Proceedings. The Borrower shall promptly execute and
deliver, or cause the execution and delivery of, all applications, certificates,
instruments, registration statements, and all other documents and papers
reasonably requested by any Credit Party in connection with the obtaining of any
consent, approval, registration (other than securities Law registrations),
qualification, permit, license, or authorization of any Tribunal or other Person
necessary or appropriate for the effective exercise of any Rights under the Loan
Documents. Because the Borrower agrees that any Credit Party's remedies at Law
for failure of the Borrower to comply with the provisions of this section would
be inadequate and that failure would not be adequately compensable in damages,
the Borrower agrees that the covenants of this section may be specifically
enforced.

         12.9 Expenditures by Lenders. Any sums spent by any Credit Party in the
exercise of any Right under any Loan Document is payable by the Companies to the
Administrative Agent within five (5) Business Days after demand, becomes part of
the Obligation, and bears interest at the Default Rate from the date spent until
the date repaid.

         12.10 Diminution in Value of Collateral. Neither the Administrative
Agent nor any Lender has any liability or responsibility whatsoever for any
diminution in or loss of value of any collateral now or in the future securing
payment or performance of any of the Obligation (other than diminution in or
loss of value caused by their or its own gross negligence or willful
misconduct).

         12.11 Expenses; Indemnification.

                  (a) The Borrower agrees to pay on demand all costs and
         expenses of Administrative Agent and the Arranger in connection with
         the syndication, preparation, execution, delivery, administration,
         modification, and amendment of this Agreement, the other Loan
         Documents, and the other documents to be delivered hereunder,
         including, without limitation, the reasonable fees and expenses of
         counsel for the Administrative Agent and the Arranger (including the
         cost of internal counsel) with respect thereto and

                                       55
<PAGE>   63

         with respect to advising Administrative Agent as to its Rights and
         responsibilities under the Loan Documents. The Borrower further agrees
         to pay on demand all costs and expenses of the Credit Parties, if any
         (including, without limitation, reasonable attorneys' fees and expenses
         and the cost of internal counsel), in connection with the enforcement
         (whether through negotiations, legal proceedings, or otherwise) of the
         Loan Documents and the other documents to be delivered hereunder.

                  (b) The Borrower agrees to indemnify and hold harmless the
         Credit Parties and each of their respective Affiliates and their
         respective officers, directors, employees, agents, and advisors (each,
         an "INDEMNIFIED PARTY") from and against any and all claims, damages,
         losses, liabilities, costs, and expenses (including, without
         limitation, reasonable attorneys' fees) that may be incurred by or
         asserted or awarded against any Indemnified Party, in each case arising
         out of or in connection with or by reason of (including, without
         limitation, in connection with any investigation, litigation, or
         proceeding or preparation of defense in connection therewith) the Loan
         Documents, any of the transactions contemplated herein or the actual or
         proposed use of the proceeds of the Obligation (INCLUDING ANY OF THE
         FOREGOING ARISING FROM THE NEGLIGENCE OF THE INDEMNIFIED PARTY), except
         to the extent such claim, damage, loss, liability, cost, or expense is
         found in a final, non-appealable judgment by a court of competent
         jurisdiction to have resulted from such Indemnified Party's gross
         negligence or willful misconduct. In the case of an investigation,
         litigation, or other proceeding to which the indemnity in this SECTION
         12.11 applies, such indemnity shall be effective whether or not such
         investigation, litigation, or proceeding is brought by any Company, its
         directors, shareholders, or creditors or an Indemnified Party or any
         other Person or any Indemnified Party is otherwise a party thereto and
         whether or not the transactions contemplated hereby are consummated.
         The Borrower agrees not to assert any claim against the Credit Parties
         or any of their respective Affiliates or any of their respective
         directors, officers, employees, attorneys, agents, and advisers, on any
         theory of liability, for special, indirect, consequential, or punitive
         damages arising out of or otherwise relating to the Loan Documents, any
         of the transactions contemplated herein or the actual or proposed use
         of the proceeds of any Borrowing.

                  (c) No Credit Party or any Affiliate, officer, director,
         employee, attorney, or agent of any Credit Party shall be liable for
         any error of judgment or act done in good faith, or be otherwise liable
         or responsible under any circumstances whatsoever (INCLUDING SUCH
         PERSON'S NEGLIGENCE), except for such Person's gross negligence or
         willful misconduct. No Credit Party or any Affiliate, officer,
         director, employee, attorney, or agent of any Credit Party shall have
         any liability with respect to, and each Company hereby waives,
         releases, and agrees not to sue any of them upon, any claim for any
         special, indirect, incidental, or consequential damage suffered or
         incurred by any Company or any of its Affiliates in connection with,
         arising out of, or in any way related to this Agreement or any of the
         other Loan Documents, or any of the transactions contemplated by this
         Agreement or any of the other Loan Documents. Each Company hereby
         waives, releases, and agrees not to sue any Credit Party or any
         Affiliate, officer, director, employee, attorney, or agent of any
         Credit Party for exemplary or punitive damages in respect of any claim
         in connection with, arising out of, or in any way related

                                       56

         to this Agreement or any of the other Loan Documents, or any of the
         transactions contemplated by this Agreement or any of the other Loan
         Documents.

                  (d) Without prejudice to the survival of any other agreement
         of the Borrower hereunder, the agreements and obligations of the
         Borrower contained in this SECTION 12.11 shall survive the payment in
         full of the Obligation and all other amounts payable under this
         Agreement.

SECTION 13: THE ADMINISTRATIVE AGENT AND LENDERS.

         13.1 Administrative Agent.

                  (a) Appointment. Each Lender appoints the Administrative Agent
         (including, without limitation, each successor to the Administrative
         Agent in accordance with this SECTION 13) as its nominee and agent to
         act in its name and on its behalf (and the Administrative Agent and
         each such successor accepts that appointment): (i) to act as its
         nominee and on its behalf in and under all Loan Documents; (ii) to
         arrange the means whereby its funds are to be made available to the
         Borrower under the Loan Documents; (iii) to take any action that it
         properly requests under the Loan Documents (subject to the concurrence
         of other Lenders as may be required under the Loan Documents); (iv) to
         receive all documents and items to be furnished to it under the Loan
         Documents; (v) to promptly distribute to it all material information,
         requests, documents, and items received from the Borrower under the
         Loan Documents; (vi) to promptly distribute to it its ratable part of
         each payment or prepayment (whether voluntary, as proceeds of
         collateral upon or after foreclosure, as proceeds of insurance thereon,
         or otherwise) in accordance with the terms of the Loan Documents; and
         (vii) to deliver to the appropriate Persons requests, demands,
         approvals, and consents received from it. However, the Administrative
         Agent is not required to take any action that exposes the
         Administrative Agent to personal liability or that is contrary to any
         Loan Document or applicable Law.

                  (b) Successor. The Administrative Agent may assign all of its
         Rights and obligations as the Administrative Agent under the Loan
         Documents to any of its Affiliates, which Affiliate shall then be the
         successor the Administrative Agent under the Loan Documents. The
         Administrative Agent may also voluntarily resign and shall resign upon
         the request of Required Lenders for cause (i.e., the Administrative
         Agent is continuing to fail to perform its responsibilities under the
         Loan Documents). If the initial, or any successor to, the
         Administrative Agent ever ceases to be a party to this Agreement or if
         either of the initial, or any successor to, the Administrative Agent
         ever resigns (whether voluntarily or at the request of the Required
         Lenders), then Required Lenders shall appoint a successor to the
         Administrative Agent from among Lenders (other than the resigning the
         Administrative Agent). If the Required Lenders fail to appoint a
         successor to such the Administrative Agent within thirty (30) days
         after the resigning the Administrative Agent has given notice of
         resignation or Required Lenders have removed the resigning
         Administrative Agent, then the resigning Administrative Agent may, on
         behalf of the Lenders, appoint a successor Administrative Agent, that
         (i) must be a commercial bank having a combined capital and surplus of
         at least $1,000,000,000 (as shown on its most recently published
         statement of condition), and (ii)

                                       57
<PAGE>   65

         must be consented to by the Borrower, which consent shall not be
         unreasonably delayed or withheld. Upon its acceptance of appointment as
         successor Administrative Agent, the successor Administrative Agent
         succeeds to and becomes vested with all of the Rights of the prior
         Administrative Agent, and the prior Administrative Agent is discharged
         from its duties and obligations as Administrative Agent under the Loan
         Documents, and each Lender shall execute the documents that any Lender,
         the resigning or removed Administrative Agent, or the successor
         Administrative Agent reasonably request to reflect the change. After
         the Administrative Agent's resignation or removal as Administrative
         Agent under the Loan Documents, the provisions of this Agreement inure
         to its benefit as to any actions taken or not taken by it while it was
         Administrative Agent under the Loan Documents.

                  (c) Rights as Lender. The Administrative Agent, in its
         capacity as a Lender, has the same Rights under the Loan Documents as
         any other Lender and may exercise those Rights as if it were not acting
         as Administrative Agent. The term "Lender", unless the context
         otherwise indicates, includes each Administrative Agent. Administrative
         Agent's resignation or removal does not impair or otherwise affect any
         Rights that it has or may have in its capacity as an individual Lender.
         Each Lender and the Borrower agree that the Administrative Agent is not
         a fiduciary for the Lenders or for the Borrower, but Administrative
         Agent is simply acting in the capacity described in this Agreement to
         alleviate administrative burdens for the Borrower and the Lenders, that
         the Administrative Agent has any duties or responsibilities to Lenders
         or the Borrower except those expressly set forth in the Loan Documents,
         and that the Administrative Agent in its capacity as a Lender has the
         same Rights as any other Lender.

                  (d) Other Activities. Any Credit Party may now or in the
         future be engaged in one or more loan, letter of credit, leasing, or
         other financing transactions with the Borrower, act as trustee or
         depositary for the Borrower, or otherwise be engaged in other
         transactions with the Borrower (collectively, the "OTHER ACTIVITIES")
         not the subject of the Loan Documents. Without limiting the Rights of
         Lenders specifically set forth in the Loan Documents, neither the
         Administrative Agent nor any Lender is responsible to account to the
         other Lenders for those other activities, and no Lender shall have any
         interest in any other Lender's activities, any present or future
         guaranties by or for the account of the Borrower that are not
         contemplated by or included in the Loan Documents, any present or
         future offset exercised by the Administrative Agent or any Lender in
         respect of those other activities, any present or future property taken
         as security for any of those other activities, or any property now or
         hereafter in the Administrative Agent's or any other Lender's
         possession or control that may be or become security for the
         obligations of the Borrower arising under the Loan Documents by reason
         of the general description of indebtedness secured or of property
         contained in any other agreements, documents, or instruments related to
         any of those other activities (but, if any payments in respect of those
         guaranties or that property or the proceeds thereof is applied by the
         Administrative Agent or any Lender to reduce the Obligation, then each
         Lender is entitled to share ratably in the application as provided in
         the Loan Documents).

         13.2 Expenses. Each Lender shall pay its Pro Rata Part of any
reasonable expenses (including, without limitation, court costs, reasonable
attorneys' fees and other costs of

                                       58
<PAGE>   66

collection) incurred by the Administrative Agent (while acting in such capacity)
in connection with any of the Loan Documents if the Administrative Agent is not
reimbursed from other sources within thirty (30) days after incurrence. Each
Lender is entitled to receive its Pro Rata Part of any reimbursement that it
makes to the Administrative Agent if the Administrative Agent is subsequently
reimbursed from other sources.

         13.3 Proportionate Absorption of Losses. Except as otherwise provided
in the Loan Documents, nothing in the Loan Documents gives any Lender any
advantage over any other Lender insofar as the Obligation is concerned or
relieves any Lender from ratably absorbing any losses sustained with respect to
the Obligation (except to the extent unilateral actions or inactions by any
Lender result in the Borrower or any other obligor on the Obligation having any
credit, allowance, set off, defense, or counterclaim solely with respect to all
or any part of that Lender's Pro Rata Part of the Obligation).

         13.4 Delegation of Duties; Reliance. The Lenders may perform any of
their duties or exercise any of their Rights under the Loan Documents by or
through the Administrative Agent, and The Lenders and the Administrative Agent
may perform any of their duties or exercise any of their Rights under the Loan
Documents by or through their respective Representatives. The Administrative
Agent, The Lenders, and their respective Representatives (a) are entitled to
rely upon (and shall be protected in relying upon) any written or oral statement
believed by them to be genuine and correct and to have been signed or made by
the proper Person and, with respect to legal matters, upon opinion of counsel
selected by the Administrative Agent or that Lender (but nothing in this CLAUSE
(a) permits the Administrative Agent to rely on (i) oral statements if a writing
is required by this Agreement or (ii) any other writing if a specific writing is
required by this Agreement), (b) are entitled to deem and treat each Lender as
the owner and holder of its portion of the Obligation for all purposes until,
written notice of the assignment or transfer is given to and received by the
Administrative Agent (and any request, authorization, consent, or approval of
any Lender is conclusive and binding on each subsequent holder, assignee, or
transferee of or Participant in that Lender's portion of the Obligation until
that notice is given and received), (c) are not deemed to have notice of the
occurrence of a Default unless a responsible officer of the Administrative
Agent, who handles matters associated with the Loan Documents and transactions
thereunder, has actual knowledge or the Administrative Agent has been notified
by a Lender or the Borrower, and (d) are entitled to consult with legal counsel
(including counsel for the Borrower), independent accountants, and other experts
selected by the Administrative Agent and are not liable for any action taken or
not taken in good faith by it in accordance with the advice of counsel,
accountants, or experts. Each Agent may execute any of its duties under this
Agreement and the other Loan Documents by or through agents or attorneys-in-fact
and shall be entitled to advice of counsel concerning all matters pertaining to
such duties. No Agent shall be responsible for the negligence or misconduct of
any agents or attorneys in-fact selected by it with reasonable care.

         13.5 Limitation of Administrative Agent's Liability.

                  (a) Exculpation. Neither the Administrative Agent nor any of
         its respective Affiliates or Representatives will be liable for any
         action taken or omitted to be taken by it or them under the Loan
         Documents in good faith and believed by them to be within the
         discretion or power conferred upon them by the Loan Documents or be
         responsible for

                                       59
<PAGE>   67

         the consequences of any error of judgment (except for fraud, gross
         negligence, or willful misconduct), and neither the Administrative
         Agent nor any of its Affiliates or Representatives has a fiduciary
         relationship with any Lender by virtue of the Loan Documents (but
         nothing in this Agreement negates the obligation of the Administrative
         Agent to account for funds received by them for the account of any
         Lender).

                  (b) Indemnity. Unless indemnified to its satisfaction against
         loss, cost, liability, and expense, the Administrative Agent is not
         compelled to do any act under the Loan Documents or to take any action
         toward the execution or enforcement of the powers thereby created or to
         prosecute or defend any suit in respect of the Loan Documents. If the
         Administrative Agent requests instructions from the Lenders, or the
         Required Lenders, as the case may be, with respect to any act or action
         in connection with any Loan Document, the Administrative Agent is
         entitled to refrain (without incurring any liability to any Person by
         so refraining) from that act or action unless and until it has received
         instructions. In no event, however, may the Administrative Agent or any
         of its Representatives be required to take any action that it or they
         determine could incur for it or them criminal or onerous civil
         liability. Without limiting the generality of the foregoing, no Lender
         has any right of action against the Administrative Agent as a result of
         the Administrative Agent's acting or refraining from acting under this
         Agreement in accordance with instructions of the Required Lenders.

                  (c) Reliance. The Administrative Agent is not responsible to
         any Lender or any Participant for, and each Lender represents and
         warrants that it has not relied upon the Administrative Agent in
         respect of, (i) the creditworthiness of any Company and the risks
         involved to that Lender, (ii) the effectiveness, enforceability,
         genuineness, validity, or the due execution of any Loan Document
         (except by the Administrative Agent), (iii) any representation,
         warranty, document, certificate, report, or statement made therein
         (except by the Administrative Agent) or furnished thereunder or in
         connection therewith, (iv) the adequacy of any collateral now or
         hereafter securing the Obligation or the existence, priority, or
         perfection of any Lien now or hereafter granted or purported to be
         granted on the collateral under any Loan Document, or (v) observation
         of or compliance with any of the terms, covenants, or conditions of any
         Loan Document on the part of any Company. EACH LENDER AGREES TO
         INDEMNIFY THE ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES AND HOLD
         THEM HARMLESS FROM AND AGAINST (BUT LIMITED TO SUCH LENDER'S PRO RATA
         PART OF) ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES,
         PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, REASONABLE EXPENSES, AND
         REASONABLE DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER THAT MAY BE
         IMPOSED ON, ASSERTED AGAINST, OR INCURRED BY THEM IN ANY WAY RELATING
         TO OR ARISING OUT OF THE LOAN DOCUMENTS OR ANY ACTION TAKEN OR OMITTED
         BY THEM UNDER THE LOAN DOCUMENTS IF THE ADMINISTRATIVE AGENT OR ITS
         REPRESENTATIVES ARE NOT REIMBURSED FOR SUCH AMOUNTS BY ANY COMPANY.
         ALTHOUGH THE ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES HAVE THE
         RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR THEIR OWN ORDINARY
         NEGLIGENCE.

         13.6 Default. While a Default exists, the Lenders agree to promptly
confer in order that the Required Lenders or the Lenders, as the case may be,
may agree upon a course of action for the enforcement of the Rights of the
Lenders. The Administrative Agent is entitled to act or

                                       60
<PAGE>   68

refrain from taking any action (without incurring any liability to any Person
for so acting or refraining) unless and until it has received instructions from
the requisite Lenders. In actions with respect to any Company's property, the
Administrative Agent is acting for the ratable benefit of each Lender.

         13.7 Collateral Matters.

                  (a) Each Lender authorizes and directs the Administrative
         Agent to enter into the Intercreditor Agreement relating to the
         Security Documents for the Lender Liens and agrees that any action
         taken by the Administrative Agent concerning any collateral in
         accordance with any Loan Document, the Administrative Agent's exercise
         of powers concerning the collateral in any Loan Document, and that all
         other reasonably incidental powers are authorized and binding upon all
         the Lenders.

                  (b) The Administrative Agent is authorized on behalf of all
         Lenders, without the necessity of any notice to or further consent from
         any Lender, from time to time before a Default or Potential Default, to
         take any action with respect to any collateral or Loan Documents
         related to collateral that may be necessary to perfect and maintain
         perfected the Lender Liens upon collateral.

                  (c) The Administrative Agent has no obligation whatsoever to
         any Lender or to any other Person to assure that collateral exists or
         is owned by any Company or is cared for, protected, or insured or has
         been encumbered or that the Lender Liens have been properly or
         sufficiently or lawfully created, perfected, protected, or enforced or
         are entitled to any particular priority.

                  (d) The Administrative Agent shall exercise the same care and
         prudent judgment with respect to collateral and the Loan Documents as
         it normally and customarily exercises in respect of similar collateral
         and security documents.

                  (e) The Lenders irrevocably authorize the Administrative
         Agent, at its option and in its discretion, to release any Lender Lien
         upon any collateral (i) constituting property being disposed of as
         permitted under any Loan Document, (ii) constituting property in which
         no Company owned any interest at the time the Lender Lien was granted
         or at any time after that, (iii) constituting property leased to any
         Company under a lease that has expired or been terminated in a
         transaction permitted under the Loan Documents or is about to expire
         and that has not been, and is not intended by that Company to be,
         renewed, (iv) consisting of an instrument evidencing Debt pledged to
         Lender Liens, if the underlying Debt has been paid in full, or (v) if
         approved, authorized, or ratified in writing by the Required Lenders.
         Upon request by the Administrative Agent at any time, Lenders shall
         confirm in writing the Administrative Agent's authority to release
         particular types or items of collateral under this CLAUSE (E).

         13.8 Limitation of Liability. No Credit Party or any Participant will
incur any liability to any other Credit Party or Participant except for acts or
omissions in bad faith, and no Credit Party or Participant will incur any
liability to any other Person for any act or omission of any other Credit Party
or any Participant.

                                       61
<PAGE>   69

         13.9 Relationship of Lenders. The Loan Documents do not create a
partnership or joint venture among the Credit Parties.

         13.10 Benefits of Agreement. None of the provisions of this section
inure to the benefit of any Company or any other Person except the Credit
Parties. Therefore, no Company or any other Person is responsible or liable for,
entitled to rely upon, or entitled to raise as a defense, in any manner
whatsoever, the failure of any Credit Party to comply with these provisions.

         13.11 Other Agents. The Agents (other than the Administrative Agent)
shall have no duties or liabilities under this Agreement and shall be entitled
to the benefits of this SECTION 13 (and SECTIONS 8.11 and 12.11) to the same
extent as the Administrative Agent.

SECTION 14: MISCELLANEOUS.

         14.1 Non-Business Days. Any payment or action that is due under any
Loan Document on a non-Business Day may be delayed until the next-succeeding
Business Day (but interest shall continue to accrue on any applicable payment
until payment is in fact made) unless the payment concerns a LIBOR Borrowing, in
which case if the next-succeeding Business Day is in the next calendar month,
then such payment shall be made on the next-preceding Business Day.

         14.2 Communications. Unless otherwise specifically provided, whenever
any Loan Document requires or permits any consent, approval, notice, request, or
demand from one party to another, communication must be in writing (which may be
by telex or fax) to be effective and shall be deemed to have been given (a) if
by telex, when transmitted to the appropriate telex number and the appropriate
answer back is received, (b) if by fax, when transmitted to the appropriate fax
number (and all communications sent by fax must be confirmed promptly thereafter
by telephone; but any requirement in this parenthetical shall not affect the
date when the fax shall be deemed to have been delivered), (c) if by mail, on
the third Business Day after it is enclosed in an envelope and properly
addressed, stamped, sealed, and deposited in the appropriate official postal
service, or (d) if by any other means, when actually delivered. Until changed by
notice pursuant to this Agreement, the address (and fax number) for the Borrower
and the Administrative Agent are stated beside their respective signatures to
this Agreement and for each Lender is stated beside its name on SCHEDULE 1.

         14.3 Form and Number of Documents. The form, substance, and number of
counterparts of each writing to be furnished under this Agreement must be
satisfactory to the Administrative Agent and its counsel.

         14.4 Exceptions to Covenants. No Company may take or fail to take any
action that is permitted as an exception to any of the covenants contained in
any Loan Document if that action or omission would result in the breach of any
other covenant contained in any Loan Document.

         14.5 Survival. All covenants, agreements, undertakings,
representations, and warranties made in any of the Loan Documents survive all
closings under the Loan Documents and, except as otherwise indicated, are not
affected by any investigation made by any party.

                                       62
<PAGE>   70

         14.6 Governing Law. This Agreement and the rights and obligations of
the parties under this Agreement shall be governed by, and construed and
interpreted in accordance with, the law of the State of New York.

         14.7 Invalid Provisions. Any provision in any Loan Document held to be
illegal, invalid, or unenforceable is fully severable; the appropriate Loan
Document shall be construed and enforced as if that provision had never been
included; and the remaining provisions shall remain in full force and effect and
shall not be affected by the severed provision. The Administrative Agent, the
Lenders, and each Company party to the affected Loan Document agree to
negotiate, in good faith, the terms of a replacement provision as similar to the
severed provision as may be possible and be legal, valid, and enforceable.

         14.8 Amendments, Consents, Conflicts, and Waivers.

                  (a) Required Lenders. Unless otherwise specifically provided
         (i) the provisions of this Agreement may be amended, modified, or
         waived, and a Subsidiary Guaranty, the Intercreditor Agreement, or
         Security Document, may be amended, or fully or partially released -
         only by an instrument in writing executed by the Borrower, the
         Administrative Agent, and the Required Lenders and supplemented only by
         documents delivered or to be delivered in accordance with the express
         terms of this Agreement, and (ii) the other Loan Documents may only be
         the subject of an amendment, modification, or waiver that has been
         approved by the Required Lenders and the Borrower.

                  (b) All Lenders. Except as specifically otherwise provided in
         this SECTION 14.8, any amendment to or consent or waiver under this
         Agreement or any Loan Document that purports to accomplish any of the
         following must be by an instrument in writing executed by the Borrower
         and the Administrative Agent and executed (or approved, as the case may
         be) by each Lender affected thereby: (i) extends the due date or
         decreases the amount of any scheduled payment or amortization of the
         Obligation beyond the date specified in the Loan Documents; (ii)
         decreases any rate or amount of interest, fees, or other sums payable
         to the Administrative Agent or the Lenders under this Agreement (except
         such reductions as are contemplated by this Agreement); (iii) changes
         the definition of "COMMITMENT," "REQUIRED LENDERS" or "PRO RATA PART";
         (iv) increases or extends the date of expiry of any one or more
         Lenders' Commitment; (v) waives compliance with, amends, or fully or
         partially releases, except as expressly provided in SECTION 5.1, any
         Subsidiary Guaranty or Security Document; or (vi) changes this CLAUSE
         (b) or any other matter specifically requiring the consent of all
         Lenders under this Agreement.

                  (c) Fees to the Administrative Agent. Any amendment or consent
         or waiver with respect to fees payable solely to the Administrative
         Agent under a separate letter agreement must be executed in writing
         only by the Administrative Agent and the Borrower.

                  (d) Conflicts. Any conflict or ambiguity between the terms and
         provisions of this Agreement and terms and provisions in any other Loan
         Document is controlled by the terms and provisions of this Agreement.

                                       63
<PAGE>   71

                  (e) Waivers. No course of dealing or any failure or delay by
         the Administrative Agent, any Lender, or any of their respective
         Representatives with respect to exercising any Right of the
         Administrative Agent or any Lender under this Agreement operates as a
         waiver thereof. A waiver must be in writing and signed by the
         Administrative Agent and the Lenders (or the Required Lenders, if
         permitted under this Agreement) to be effective, and a waiver will be
         effective only in the specific instance and for the specific purpose
         for which it is given.

         14.9 Multiple Counterparts. Any Loan Document may be executed in a
number of identical counterparts (including, at the Administrative Agent's
discretion, counterparts or signature pages executed and transmitted by fax)
with the same effect as if all signatories had signed the same document. All
counterparts must be construed together to constitute one and the same
instrument.

         14.10 Parties.

                  (a) Parties Bound. Each Loan Document binds and inures to the
         parties to it, any intended beneficiary of it, and each of their
         respective successors and permitted assigns. No Company may assign or
         transfer any Rights or obligations under any Loan Document without
         first obtaining all the Lenders' consent, and any purported assignment
         or transfer without the Lenders' consent is void. No Lender may
         transfer, pledge, assign, sell any participation in, or otherwise
         encumber its portion of the Obligation except as permitted by CLAUSES
         (b) or (c) below.

                  (b) Participations. Any Lender may (subject to the provisions
         of this section, in accordance with applicable Law, in the ordinary
         course of its business, and at any time) sell to one or more Persons
         (each a "PARTICIPANT") participating interests in its portion of the
         Obligation. The selling Lender remains a "Lender" under the Loan
         Documents, the Participant does not become a "Lender" under the Loan
         Documents, and the selling Lender's obligations under the Loan
         Documents remain unchanged. The selling Lender remains solely
         responsible for the performance of its obligations and remains the
         holder of its Term Loan for all purposes under the Loan Documents. The
         Borrower and the Administrative Agent shall continue to deal solely and
         directly with the selling Lender in connection with that Lender's
         Rights and obligations under the Loan Documents, and each Lender must
         retain the sole right and responsibility to enforce due obligations of
         the Companies. Participants have no Rights under the Loan Documents
         except as provided below. Subject to the following, each Lender may
         obtain (on behalf of its Participants) the benefits of SECTION 3 with
         respect to all participations in its part of the Obligation outstanding
         from time to time so long as the Borrower is not obligated to pay any
         amount in excess of the amount that would be due to that Lender under
         SECTION 3 calculated as though no participations have been made. No
         Lender may sell any participating interest under which the Participant
         has any Rights to approve any amendment, modification, or waiver of any
         Loan Document except as to matters in SECTION 14.8(b)(i) and (ii).

                  (c) Assignments. Each Lender may make assignments to the
         Federal Reserve Bank. Each Lender may also assign to one or more
         assignees (each an "ASSIGNEE") all or

                                       64
<PAGE>   72

         any part of its Rights and obligations under the Loan Documents so long
         as (i) the assignor Lender and the Assignee execute and deliver to the
         Administrative Agent and the Borrower for their consent and acceptance
         (that may not be unreasonably withheld in any instance and is not
         required if the Assignee is an Affiliate of the assigning Lender) an
         assignment and assumption agreement in substantially the form of
         EXHIBIT F (an "ASSIGNMENT") and pay to the Administrative Agent a
         processing fee of $2,500, (ii) except in the case of assignments to a
         Lender on an affiliate of a Lender, the assignment must be for a
         minimum total amount of $5,000,000 and, if the assigning Lender retains
         any amount, it must be a minimum total amount of $5,000,000, (iii) the
         conditions for that assignment set forth in the applicable Assignment
         are satisfied and (iv) notice is given to Syndication Agent; provided,
         however, that so long as a Default has occurred and is continuing (A)
         the Borrower's consent shall not be required for an assignment to any
         Eligible Assignee, and (B) the minimum amounts described in subsection
         (iii) above shall not be required; provided, further, that in the case
         of any assignment by the Syndication Agent, neither the Borrower's
         consent nor the Administrative Agent's consent shall be required. The
         Effective Date in each Assignment must (unless a shorter period is
         agreeable to the Borrower and the Administrative Agent) be at least
         five (5) Business Days after it is executed and delivered by the
         assignor Lender and the Assignee to the Administrative Agent and the
         Borrower for acceptance. Once that Assignment is accepted by the
         Administrative Agent and the Borrower, and subject to all of the
         following occurring, then, on and after the Effective Date stated in it
         (i) the Assignee automatically becomes a party to this Agreement and,
         to the extent provided in that Assignment, has the Rights and
         obligations of a Lender under the Loan Documents, (ii) the assignor
         Lender, to the extent provided in that Assignment, is released from its
         obligations under this Agreement and its reimbursement obligations
         under this Agreement and, in the case of an Assignment covering all of
         the remaining portion of the assignor Lender's Rights and obligations
         under the Loan Documents, that Lender ceases to be a party to the Loan
         Documents, (iii) the Borrower shall execute and deliver to the assignor
         Lender and the Assignee the appropriate Notes, if requested, in
         accordance with this Agreement following the transfer, and (iv) upon
         delivery of the Notes, if any, under CLAUSE (III) preceding, the
         assignor Lender shall return to the Borrower all Notes, if any,
         previously delivered to that Lender under this Agreement.
         Notwithstanding the foregoing, no Assignee may be recognized as a party
         to the Loan Documents (and the assigning Lender shall continue to be
         treated for all purposes as the party to the Loan Documents) with
         respect to the Rights and obligations assigned to that Assignee until
         the actions described in CLAUSES (III) and (IV) have occurred and until
         the Assignment to such Assignee is registered on the books of the
         Borrower as to both principal and any stated interest. The Obligation
         is registered on the books of the Borrower as to both principal and any
         stated interest, and transfers of (as opposed to participations in)
         principal and interest of the Obligation may only be made in accordance
         with this SECTION 14.10.

         For purposes of this section, "ELIGIBLE ASSIGNEE" shall mean: (i) a
commercial bank or savings and loan association and having total assets in
excess of $100,000,000; (ii) a finance company, insurance company or other
financial institution, lender or fund (whether a corporation, partnership or
other entity) which is engaged in making, purchasing or otherwise investing in
commercial loans in the ordinary course of its business, and having total assets
in excess of at least $100,000,000; or (iii) any Lender or any Affiliate of any
Lender; provided,

                                       65
<PAGE>   73

however, that neither the Borrower nor any Affiliate of the Borrower shall
qualify as an Eligible Assignee.

         14.11 Submission To Jurisdiction; Waivers. Each of the Borrower and
each Subsidiary Guarantor hereby irrevocably and unconditionally:

                  (a) submits for itself and its property in any legal action or
         proceeding relating to this Agreement and the other Loan Documents to
         which it is a party, or for recognition and enforcement of any judgment
         in respect thereof, to the non-exclusive general jurisdiction of the
         courts of the State of New York, the courts of the United States for
         the Southern District of New York, and appellate courts from any
         thereof;

                  (b) consents that any such action or proceeding may be brought
         in such courts and waives any objection that it may now or hereafter
         have to the venue of any such action or proceeding in any such court or
         that such action or proceeding was brought in an inconvenient court and
         agrees not to plead or claim the same;

                  (c) agrees that service of process in any such action or
         proceeding may be effected by mailing a copy thereof by registered or
         certified mail (or any substantially similar form of mail), postage
         prepaid, to the Borrower, as the case may be at its address set forth
         on Schedule 1 or at such other address of which the Administrative
         Agent shall have been notified pursuant thereto; and

                  (d) agrees that nothing herein shall affect the right to
         effect service of process in any other manner permitted by law or shall
         limit the right to sue in any other jurisdiction.

                  The scope of each of the foregoing waivers 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, without limitation,
contract claims, tort claims, breach of duty claims, and all other common law
and statutory claims. THE BORROWER AND EACH SUBSIDIARY GUARANTOR ACKNOWLEDGES
THAT THESE WAIVERS ARE A MATERIAL INDUCEMENT TO THE ADMINISTRATIVE AGENT'S AND
EACH LENDER'S AGREEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT THE
ADMINISTRATIVE AGENT AND EACH LENDER HAVE ALREADY RELIED ON THESE WAIVERS IN
ENTERING INTO THIS AGREEMENT, AND THAT THE ADMINISTRATIVE AGENT AND EACH LENDER
WILL CONTINUE TO RELY ON EACH OF THESE WAIVERS IN RELATED FUTURE DEALINGS. THE
BORROWER AND EACH SUBSIDIARY GUARANTOR FURTHER WARRANTS AND REPRESENTS THAT IT
HAS REVIEWED THESE WAIVERS WITH ITS LEGAL COUNSEL, AND THAT IT KNOWINGLY AND
VOLUNTARILY AGREES TO EACH WAIVER FOLLOWING CONSULTATION WITH LEGAL COUNSEL. The
waivers in this section are irrevocable, meaning that they may not be modified
either orally or in writing, and these waivers apply to any future renewals,
extensions, amendments, modifications, or replacements in respect of the
applicable Loan Document. In connection with any Litigation, this Agreement may
be filed as a written consent to a trial by the court.

         14.12 Confidentiality Obligations. All nonpublic information furnished
by any Company to the Administrative Agent or the Lenders pursuant to this
Agreement (that is

                                       66
<PAGE>   74

designated by such Company to the Administrative Agent and the Lenders as
nonpublic information) will be treated as confidential, but nothing herein
contained shall limit or impair the Administrative Agent's or any Lender's
Rights (and the Administrative Agent or such Lender shall be entitled) (a) to
disclose the same to any Tribunal, if required to do so, or to any prospective
or actual Assignee or Participant (provided that such prospective or actual
Assignee or Participant agrees to comply with this SECTION 14.12), or to the
respective affiliates, directors, officers, employees, attorneys, and agents of
the Administrative Agent or such Lender or any prospective or actual Assignee or
Participant, (b) to use such information to the extent pertinent to an
evaluation of the Obligation, (c) to enforce compliance for the terms and
conditions of the Loan Documents, or (d) to take any action which the
Administrative Agent or such Lender deems necessary to protect its interests if
a Default has occurred and is continuing.

         14.13 Entirety. THE LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT
BETWEEN THE BORROWER, THE LENDERS, AND THE ADMINISTRATIVE AGENT AND 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.

         14.14 WAIVERS OF JURY TRIAL. THE BORROWER, EACH SUBSIDIARY GUARANTOR,
THE AGENTS AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY
JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER
LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

         14.15 Intercreditor Agreement. Each of the Lenders hereby consents to
the execution of the Intercreditor Agreement and the appointment of Wells Fargo
Bank Texas, National Association to act as "Collateral Agent" in accordance with
the terms thereof for the Lenders and the lenders under the Existing Credit
Agreement.

SECTION 15: SUBSIDIARY GUARANTY.

         15.1 The Guaranty. In order to induce the Credit Parties to enter into
this Agreement and to extend credit hereunder and in recognition of the direct
benefits to be received by Subsidiary Guarantors from the proceeds of the Term
Loans made to the Borrower hereunder, each Subsidiary Guarantor hereby,
unconditionally and irrevocably, guarantees as primary obligor and not merely as
surety the full and prompt payment when due, whether upon maturity, by
acceleration or otherwise, of any and all of the Obligation. If any or all of
the Obligation becomes due and payable, each Subsidiary Guarantor
unconditionally, jointly and severally, promises to pay such Obligation to the
Credit Parties, or order, on demand, together with any and all expenses which
may be incurred by each Credit Party in collecting any of the Obligation. The
word "OBLIGATION" is used in this SECTION 15 in its most comprehensive sense and
includes any and all advances, debts, obligations (including obligations which,
but for any automatic stay under the Debtor Laws, would become due, and
including interest accruing after the maturity of the Term Loans and interest
accruing after the filing of any petition in bankruptcy, or the commencement of
any insolvency, reorganization or like proceeding, relating to the Borrower,
whether or not a claim for post-filing or post-petition interest is allowed in
such proceeding), and obligations of the Borrower arising in connection with
this Agreement or any other Loan

                                       67
<PAGE>   75
Document, in each case, heretofore, now, or hereafter made, incurred, or
created, whether voluntarily or involuntarily, absolute or contingent,
liquidated or unliquidated, determined or undetermined, whether or not such
indebtedness is from time to time reduced, or extinguished and thereafter
increased or incurred, whether the Borrower may be liable individually or
jointly with others, whether or not recovery upon such indebtedness may be or
hereafter become barred by any statute of limitations, and whether or not such
indebtedness may be or hereafter become otherwise unenforceable.

         15.2 Bankruptcy. Additionally, each Subsidiary Guarantor, jointly and
severally, unconditionally and irrevocably guarantees the payment of any and all
indebtedness of the Borrower to the Credit Parties whether or not due or payable
by the Borrower upon the occurrence in respect of the Borrower of any of the
events specified in SECTION 11.3, and unconditionally promises to pay such
indebtedness to the Credit Parties, or order, on demand, in lawful money of the
United States.

         15.3 Nature of Liability. The liability of each Subsidiary Guarantor
hereunder is exclusive and independent of any security for or other guaranty of
the indebtedness of the Borrower whether executed by such Subsidiary Guarantor,
any other guarantor, or by any other party, and the liability of such Subsidiary
Guarantor hereunder shall not be affected or impaired by (a) any direction as to
application of payment by the Borrower, or by any other party, or (b) any other
continuing or other guaranty, undertaking, or maximum liability of a guarantor
or of any other party as to the indebtedness of the Borrower, or (c) any payment
on or in reduction of any such other guaranty or undertaking, or (d) any
dissolution, termination, or increase, decrease, or change in personnel by the
Borrower, or (e) any payment made to any Credit Party on the indebtedness which
such Credit Party repays The Borrower pursuant to court order in any bankruptcy,
reorganization, arrangement, moratorium, or other debtor relief proceeding, and
each Subsidiary Guarantor waives any right to the deferral or modification of
its obligations hereunder by reason of any such proceeding. This Subsidiary
Guaranty is intended to be an irrevocable, absolute, continuing guaranty of
payment and is not a guaranty of collection. This Subsidiary Guaranty may not be
revoked by any Subsidiary Guarantor; provided, however, if, according to
applicable law, it shall ever be determined or held that a guarantor under a
continuing guaranty such as this Subsidiary Guaranty shall have the absolute
right, notwithstanding the express agreement of such a guarantor otherwise, to
revoke such guaranty as to any Obligation which has then not yet arisen, then
any Subsidiary Guarantor may deliver to the Administrative Agent written notice
that such Subsidiary Guarantor will not be liable hereunder for any of the
Obligation created, incurred, or arising after the giving of such notice, and
such notice will be effective as to such Subsidiary Guarantor from and after
(but not before) such times as said written notice is actually delivered to and
received by and receipted for in writing by the Administrative Agent; provided
that such notice shall not in anywise affect, impair, or limit the liability and
responsibility of any other person or entity with respect to any of the
Obligation theretofore existing or thereafter existing, arising, renewed,
extended, or modified; provided, further, that such notice shall not affect,
impair, or release the liability and responsibility of such Subsidiary Guarantor
with respect to any of the Obligation created, incurred, or arising prior to the
receipt of such notice by the Administrative Agent as aforesaid, or in respect
of any renewals, extensions, or modifications of such Obligation, or in respect
of interest or costs of collection thereafter incurred on or with respect to
such Obligation, or with respect to attorneys' fees thereafter becoming payable
hereunder with respect to such Obligation,

                                       68
<PAGE>   76
and shall continue to be effective with respect to any Obligation arising or
created after any attempted revocation by any Subsidiary Guarantor.

         15.4 Independent Obligation. The obligations of each Subsidiary
Guarantor hereunder are independent of the obligations of any other guarantor or
the Borrower, and a separate action or actions may be brought and prosecuted
against each Subsidiary Guarantor whether or not action is brought against any
other guarantor or the Borrower and whether or not any other guarantor or The
Borrower be joined in any such action or actions. Each Subsidiary Guarantor
waives, to the fullest extent permitted by law, the benefit of any statute of
limitations affecting its liability hereunder or the enforcement thereof. Any
payment by the Borrower or other circumstance which operates to toll any statute
of limitations as to the Borrower shall operate to toll the statute of
limitations as to each Subsidiary Guarantor.

         15.5 Authorization. Each Subsidiary Guarantor authorizes the Credit
Parties without notice or demand (except as shall be required by applicable
statute and cannot be waived), and without affecting or impairing its liability
hereunder, from time to time to (a) renew, compromise, extend, increase,
accelerate, or otherwise change the time for payment of, or otherwise change the
terms of the indebtedness or any part thereof in accordance with this Subsidiary
Guaranty, including any increase or decrease of the rate of interest thereon,
(b) take and hold security from any guarantor or any other party for the payment
of this guaranty or the indebtedness and exchange, enforce, waive, and release
any such security, (c) apply such security and direct the order or manner of
sale thereof as the Credit Parties in their discretion may determine, and (d)
release or substitute any one or more endorsers, guarantors, the Borrower, or
other obligors.

         15.6 Reliance. It is not necessary for any Credit Party to inquire into
the capacity or powers of any Company or the officers, directors, partners, or
agents acting or purporting to act on its behalf, and any indebtedness made or
created in reliance upon the professed exercise of such powers shall be
guaranteed hereunder.

         15.7 Subordination. Any indebtedness of the Borrower now or hereafter
held by any Subsidiary Guarantor is hereby subordinated to the indebtedness of
the Borrower to the Credit Parties; and such indebtedness of the Borrower to any
Subsidiary Guarantor, if the Administrative Agent, after a Default has occurred
and is continuing, so requests, shall be collected, enforced, and received by
such Subsidiary Guarantor as trustee for the Credit Parties and be paid over to
the Credit Parties on account of the indebtedness of the Borrower to the Credit
Parties, but without affecting or impairing in any manner the liability of such
Subsidiary Guarantor under the other provisions of this Guaranty. Prior to the
transfer by any Subsidiary Guarantor of any note or negotiable instrument
evidencing any indebtedness of the Borrower to such Subsidiary Guarantor, such
Subsidiary Guarantor shall mark such note or negotiable instrument with a legend
that the same is subject to this subordination.

         15.8 Waivers; Consents.

                  (a) Each Subsidiary Guarantor waives any right (except as
         shall be required by applicable statute and cannot be waived) to
         require any Credit Party to (i) proceed against the Borrower, any other
         guarantor, or any other party, (ii) proceed against or

                                       69
<PAGE>   77

         exhaust any security held from the Borrower, any other guarantor, or
         any other party, or (iii) pursue any other remedy in any Credit Party's
         power whatsoever. Each Subsidiary Guarantor waives any defense based on
         or arising out of any defense of the Borrower, any other guarantor, or
         any other party other than payment in full of the indebtedness,
         including, without limitation, any defense based on or arising out of
         the disability of the Borrower, any other guarantor, or any other
         party, or the unenforceability of the indebtedness or any part thereof
         from any cause, or the cessation from any cause of the liability of the
         Borrower other than payment in full of the indebtedness. The Credit
         Parties may, at their election, foreclose on any security held by any
         Credit Party by one or more judicial or nonjudicial sales, whether or
         not every aspect of any such sale is commercially reasonable (to the
         extent such sale is permitted by applicable law), or exercise any other
         right or remedy the Administrative Agent and the Lenders may have
         against the Borrower or any other party, or any security, without
         affecting or impairing in any way the liability of any Subsidiary
         Guarantor hereunder except to the extent the indebtedness has been
         paid. Each Subsidiary Guarantor waives any defense arising out of any
         such election by the Credit Parties, even though such election operates
         to impair or extinguish any right of reimbursement or subrogation or
         other right or remedy of any Subsidiary Guarantor against the Borrower
         or any other party or any security.

                  (b) Each Subsidiary Guarantor waives all presentments, demands
         for performance, protests, and notices, including without limitation
         notices of nonperformance, notice of protest, notices of dishonor,
         notices of acceptance of this Guaranty, and notices of the existence,
         creation, or incurring of new or additional indebtedness. Each
         Subsidiary Guarantor assumes all responsibility for being and keeping
         itself informed of the Borrower's financial condition and assets, and
         of all other circumstances bearing upon the risk of nonpayment of the
         indebtedness and the nature, scope, and extent of the risks which each
         Subsidiary Guarantor assumes and incurs hereunder, and agrees that the
         Credit Parties shall have no duty to advise Subsidiary Guarantors of
         information known to them regarding such circumstances or risks.

                  (c) Any Credit Party may at any time and from time to time
         without the consent of, or notice to, any Subsidiary Guarantor, without
         incurring responsibility to such Subsidiary Guarantor, without
         impairing or releasing the obligations of such Subsidiary Guarantor
         hereunder, upon or without any terms or conditions and in whole or in
         part: (i) change the manner, place, or terms of payment of, and/or
         change or extend the time of payment of, renew, or alter, any of the
         Obligation, any security therefor, or any liability incurred directly
         or indirectly in respect thereof, and the guaranty herein made shall
         apply to the Obligation as so changed, extended, renewed, or altered;
         (ii) sell, exchange, release, surrender, realize upon, or otherwise
         deal with in any manner and in any order any property by whomsoever at
         any time pledged or mortgaged to secure, or howsoever securing, the
         Obligation or any liabilities (including any of those hereunder)
         incurred directly or indirectly in respect thereof or hereof, and/or
         any offset there against; (iii) exercise or refrain from exercising any
         rights against the Borrower, any other guarantor, or others or
         otherwise act or refrain from acting; (iv) settle or compromise any of
         the Obligation, any security therefor, or any liability (including any
         of those hereunder) incurred directly or indirectly in respect thereof

         due or not) of the Borrower to creditors of the Borrower (other than
         the Credit Parties); (v) apply any sums by whomsoever paid or howsoever
         realized to any liability or liabilities of the Borrower to the Credit
         Parties regardless of what liabilities of such Borrower remain unpaid;
         (vi) consent to or waive any breach of, or any act, omission or default
         under, any of the Loan Documents, or any of the instruments or
         agreements referred to therein, or otherwise amend, modify, or
         supplement any of the Loan Documents or any of such other instruments
         or agreements; and/or (vii) act or fail to act in any manner referred
         to in this Subsidiary Guaranty which may deprive such Subsidiary
         Guarantor of its right to subrogation against the Borrower to recover
         full indemnity for any payments made pursuant to this Subsidiary
         Guaranty.

         15.9 Limitation. It is the intention of Subsidiary Guarantors and the
Credit Parties that the amount of the Obligation guaranteed hereby shall be in,
but not in excess of, the maximum amount permitted by fraudulent conveyance,
fraudulent transfer, or other similar laws applicable to Subsidiary Guarantors.
Accordingly, anything herein or in any other Loan Document notwithstanding, the
maximum liability of each Subsidiary Guarantor hereunder and under the other
Loan Documents shall in no event exceed the amount which can be guaranteed by
such Subsidiary Guarantor under applicable federal and state laws relating to
the insolvency of debtors.

         15.10 Additional Guarantors. From time to time subsequent to the time
hereof, After-Acquired Subsidiaries may become parties hereto as additional
Subsidiary Guarantors by executing a counterpart to this Subsidiary Guaranty in
the form of EXHIBIT B. Upon delivery of any such counterpart to the
Administrative Agent, notice of which is hereby waived by each Subsidiary
Guarantor, each such After-Acquired Subsidiary shall be a Subsidiary Guarantor
and shall be a party hereto as if such After-Acquired Subsidiary were an
original signatory hereof. Each Subsidiary Guarantor expressly agrees that its
obligations arising hereunder shall not be affected or diminished by the
addition or release of any other Subsidiary Guarantor hereunder, or by any
election by the Administrative Agent not to cause any After-Acquired Subsidiary
to become a Subsidiary Guarantor hereunder. This Subsidiary Guaranty shall be
fully effective as to any Subsidiary Guarantor that is or becomes a party hereto
regardless of whether any such person becomes or fails to become or ceases to be
a Subsidiary Guarantor hereunder.
