         ACCORDINGLY, for adequate and sufficient consideration, ACS, other

than 50% of any class of Voting Stock (or similar ownership interests) of any

of such currency for such purposes. If, after the issuance of an LC in an

         Issuer, Administrative Agent, or any other Person. From the date that
         the applicable LC Issuer pays a draft under a LC until the date of
         demand for reimbursement is made, the Dollar Equivalent of unpaid
         reimbursement obligations shall accrue interest at the Base Rate, which
         accrued interest shall be payable on demand; and, thereafter until the
         related reimbursement obligation of Borrowers is paid or funded by
         proceeds of a Borrowing, the Dollar

         amount of any draft presented for honor under any LC issued by such LC
         Issuer (but failure to give any such notice shall not affect Borrowers'
         obligations under this Agreement). The applicable LC Issuer shall pay
         the Dollar Equivalent of the requested amount upon presentment of a
         draft for honor unless such presentment on its face does not comply

         that exists under any other agreement and (ii) the obligations under
         any other agreement that have or have not been performed by the
         beneficiary or any other Person (and the applicable LC Issuer shall not
         be liable for any obligation of any Person thereunder). Borrowers'
         reimbursement obligations to the LC Issuers, Administrative Agent, and
         Lenders, and each Lender's obligations to the LC Issuers and

         sufficiency, accuracy, or genuineness of documents or endorsements
         which appear appropriate on their face (even if they are in any respect
         invalid, unenforceable, insufficient, inaccurate, fraudulent, or
         forged), (ii) any dispute by any Company with or any Company's claims,
         setoffs, defenses, counterclaims, or other Rights against any LC
         Issuer, Administrative Agent, any Lender, or any other Person, or (iii)
         the occurrence of any Potential Default or Default. However, nothing in
         this SECTION 2.2 constitutes a waiver of the Rights of any Borrower or
         any Lender to assert any claim or defense based upon the gross
         negligence or willful misconduct of any LC Issuer. To the extent any
         Lender has funded its ratable share of any draft under an LC, then
         Administrative Agent shall promptly distribute reimbursement payments
         received from Borrowers to such Lender according to its ratable share.
         In the event any payment by Borrowers received by Administrative Agent
         with respect to any LC and distributed to Lenders on account of their
         participations therein is thereafter set aside, avoided, or recovered
         from Administrative Agent in connection with any receivership,
         liquidation, or bankruptcy proceeding, each Lender which received such
         distribution shall, upon demand by Administrative Agent, contribute
         such Lender's ratable portion of the Dollar Equivalent of the amount
         set aside, avoided, or recovered, together with interest at the rate
         required to be paid by Administrative Agent upon the amount required to
         be repaid by it.

                  (e) Obligation of Lenders. If Borrowers fail to reimburse any
         LC Issuer as provided in SECTION 2.2(c) within one (1) Business Day of
         the demand therefor by such LC Issuer and funds cannot be advanced
         under the Revolver Facility to satisfy the reimbursement obligations,
         then such LC Issuer shall promptly notify Administrative Agent of such
         fact and Administrative Agent shall promptly notify each Lender of
         Borrowers' failure, of the date and the Dollar Equivalent of the amount
         of the draft paid, and of such Lender's Commitment Percentage thereof.
         Each Lender shall promptly and unconditionally fund its participation
         interest in such unreimbursed draft by making available to
         Administrative Agent (for the benefit of the relevant LC Issuer) in
         Dollars in immediately available funds such Lender's Commitment
         Percentage of the Dollar Equivalent of the unreimbursed draft. Funds
         are due and payable to Administrative Agent on or before 1:00 p.m.,
         Dallas, Texas time on the Business Day when Administrative Agent gives
         notice to each Lender of Borrowers' reimbursement failure (if given
         prior to 10:00 a.m., Dallas, Texas time) or on the next succeeding
         Business Day (if notice was given after 10:00 a.m., Dallas, Texas
         time). All amounts payable by any Lender shall accrue interest at the
         Federal Funds Rate from the day the applicable draft is paid by the
         relevant LC Issuer to (but not including) the date the amount is paid
         by the Lender to Administrative Agent.

<PAGE>

                  (f) Duties of LC Issuers. Each LC Issuer agrees with each
         Lender that it will exercise and give the same care and attention to
         each LC that it issues as it gives to its other letters of credit. No
         LC Issuer shall have any liability to any Lender with respect to such
         LCs (other than liability arising from the gross negligence or willful
         misconduct of such LC Issuer). Each Lender and each Borrower agree
         that, in paying any draw under any LC, no LC Issuer shall have any
         responsibility to obtain any document (other than any documents
         required by the respective LC) or to ascertain or inquire as to any
         document's validity, enforceability, sufficiency, accuracy, or
         genuineness or the authority of any Person delivering any such
         document. LC Issuers, Administrative Agent, Lenders, and their
         respective Representatives shall not be liable to any other Lender or
         any Company for any LC's use or for any beneficiary's acts or
         omissions. Any action, inaction, error, delay, or omission taken or
         suffered by any LC Issuer, Administrative Agent, or any of their
         Representatives under or in connection with any LC, applicable drafts
         or documents, or the transmission, dispatch, or delivery of any related
         message or advice, if in good faith and in conformity with such Laws as
         any LC Issuer, Administrative Agent, or any of their Representatives
         may deem applicable and in accordance with the standards of care
         specified in the Uniform Customs and Practice for Documentary Credits
         issued by the International Chamber of Commerce, as in effect on the
         date of issue of such LC, shall be binding upon the Companies and
         Lenders and shall not place any LC Issuer, Administrative Agent, or any
         of their Representatives under any resulting liability to any Company
         or any Lender. No less than once each month, each LC Issuer shall give
         a summary report of the issued and outstanding LCs of such LC Issuer to
         Administrative Agent, in form and substance satisfactory to
         Administrative Agent, and Administrative Agent shall distribute such
         summary reports to Lenders promptly upon receipt thereof.

                  (g) Cash Collateral. On the Termination Date, or on any date
         that the LC Exposure exceeds the then-effective commitment under the LC
         Subfacility, or upon any demand by any LC Issuer upon the occurrence
         and during the continuance of a Default, Borrowers shall provide to
         Administrative Agent, for the benefit of LC Issuers and Lenders, (i)
         cash collateral in Dollars in an amount equal to 100% of the Dollar
         Equivalent of the LC Exposure existing on such date, such cash and all
         interest thereon shall constitute cash collateral for all LCs, and (ii)
         such additional cash collateral as any LC Issuer or Administrative
         Agent may from time to time require, so that the cash collateral amount
         shall at all times equal or exceed 100% of the Dollar Equivalent of the
         LC Exposure. Any cash collateral deposited under this CLAUSE (g), and
         all interest earned thereon, shall be held by Administrative Agent and
         invested and reinvested at the expense and the written direction of
         Borrowers in U.S. Treasury Bills with maturities of no more than ninety
         (90) days from the date of investment and all interest paid thereon
         shall remain property of Borrowers. Without limiting the Rights of
         Administrative Agent and any LC Issuer, if any draft under any LC is
         presented for payment and Borrowers do not reimburse the applicable LC
         Issuer within the time period required by this SECTION 2.2, after
         notice from the applicable LC Issuer of such failure, Administrative
         Agent may apply any cash collateral held by Administrative Agent to the
         reimbursement obligation. Any costs related to liquidation or breakage
         prior to maturity of any investment shall be borne by Borrowers.

                  (h) INDEMNIFICATION. EACH BORROWER SHALL PROTECT, INDEMNIFY,
         PAY, AND SAVE EACH LC ISSUER, ADMINISTRATIVE AGENT, AND EACH LENDER
         HARMLESS FROM AND AGAINST THE DOLLAR EQUIVALENT OF ANY AND ALL CLAIMS,
         DEMANDS, LIABILITIES, DAMAGES, OR LOSSES OF, OR OWED TO THIRD PARTIES
         (INCLUDING ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF ANY LC
         ISSUER, ADMINISTRATIVE AGENT, LENDERS, OR THEIR RESPECTIVE
         REPRESENTATIVES), AND ANY AND ALL RELATED COSTS, CHARGES, AND EXPENSES
         (INCLUDING REASONABLE ATTORNEYS' FEES), WHICH ANY LC ISSUER,
         ADMINISTRATIVE AGENT, OR ANY LENDER MAY INCUR OR BE SUBJECT TO AS A
         CONSEQUENCE, DIRECT OR INDIRECT, OF (I) THE ISSUANCE OF ANY LC, (II)
         ANY DISPUTE


                                       19                  ACS CREDIT AGREEMENT
<PAGE>

         ABOUT A LC, OR (III) THE FAILURE OF ANY LC ISSUER TO HONOR A DRAFT
         UNDER SUCH LC AS A RESULT OF ANY ACT OR OMISSION (WHETHER RIGHT OR
         WRONG) OF ANY PRESENT OR FUTURE GOVERNMENTAL AUTHORITY. HOWEVER, NO
         PERSON IS ENTITLED TO INDEMNITY HEREUNDER FOR ITS OWN GROSS NEGLIGENCE
         OR WILLFUL MISCONDUCT. THE FOREGOING INDEMNITY PROVISIONS SHALL SURVIVE
         THE SATISFACTION AND PAYMENT OF THE OBLIGATION AND TERMINATION OF THIS
         AGREEMENT.

                  (i) LC Agreements. Although referenced in any LC, terms of any
         particular agreement or other obligation to the beneficiary are not
         incorporated into this Agreement in any manner. The fees and other
         amounts payable with respect to each LC are as provided in this
         Agreement, drafts under any LC shall be deemed part of the Obligation,
         and in the event of any conflict between the terms of this Agreement
         and any LC Agreement, the terms of this Agreement shall be controlling.

                  (j) Currency Fluctuation. If as a result of fluctuations in
         currency exchange rates (which shall be calculated by Administrative
         Agent no less often than monthly), the aggregate of the Commitment
         Usage exceeds the amount of the Revolver Commitment, the Borrowers
         shall within 5 Business Days prepay outstanding Principal Debt in an
         amount equal to such excess or, if such excess is greater than the
         amount of all outstanding Principal Debt, shall within 5 Business Days
         prepay all outstanding Principal Debt and deliver to Administrative
         Agent cash collateral in an amount equal to the remaining excess after
         giving effect to such prepayment.

                  (k) Existing Letters of Credit. All Existing Letters of Credit
         shall be deemed to have been issued pursuant to this Agreement, and
         after the Closing Date shall be subject to and governed by the terms
         and conditions of this Agreement; provided that Borrowers shall not be
         required to pay the fees required by SECTION 5.5(b) with respect to the
         issuance of such Existing Letters of Credit, but shall be obligated to
         pay such fees with respect to any extensions of such Existing Letters
         of Credit.

         2.3 SWING LINE SUBFACILITY.

                  (a) For the convenience of the parties and as an integral part
         of the transactions contemplated by the Loan Documents, Swing Line
         Lender, solely for its own account, agrees to make any requested
         Borrowing of $100,000 or a greater integral multiple thereof, subject
         to those terms and conditions applicable to Borrowings set forth in
         SECTIONS 7.2(c) through (e), directly to Borrowers as a Swing Line
         Borrowing without requiring any other Lender to fund its Pro Rata Part
         thereof unless and until SECTION 2.3(b) is applicable; provided that:
         (i) each Swing Line Borrowing must occur on a Business Day and no later
         than the Business Day immediately preceding the Termination Date; (ii)
         the aggregate Swing Line Principal Debt outstanding on any date of
         determination shall not exceed the Swing Line Commitment; (iii) on any
         date of determination, the Revolver Commitment Usage shall never exceed
         the Revolver Commitment; (iv) the Principal Debt outstanding on any
         date of determination shall not exceed the Revolver Commitment then in
         effect; (v) at the time of such Swing Line Borrowing, no Default or
         Potential Default shall have occurred and be continuing; (vi) each
         Swing Line Borrowing shall bear interest at a rate per annum equal to
         the Base Rate; provided that at any time after Lenders are deemed to
         have purchased, pursuant to SECTION 2.3(b), a participation in any
         Swing Line Borrowing, such Borrowing shall bear interest at the Default
         Rate; and (vii) no additional Swing Line Borrowing shall be made at any
         time after any Lender has refused, notwithstanding the requirements of
         SECTION 2.3(b), to purchase a participation in any Swing Line Borrowing
         as provided in such Section, and until such purchase shall occur or
         until the Swing Line Borrowing has been repaid. Each Swing Line
         Borrowing shall be available and may be prepaid on same day telephonic
         notice from any Borrower to Swing Line Lender, so long as such notice
         is received by Swing Line


                                       20                  ACS CREDIT AGREEMENT
<PAGE>

         Lender prior to 2:00 p.m., Dallas, Texas time. Accrued interest on
         Swing Line Borrowings shall be due and payable on the 10th Business Day
         of each of January, April, July, and October and on the Termination
         Date.

                  (b) Borrowers shall be jointly and severally liable for all
         Swing Line Borrowings. Borrowings under the Swing Line Subfacility
         shall be due no later than five Business Days after such Swing Line
         Borrowing is made. If Borrowers fail to repay any Swing Line Borrowing
         as provided herein, then Borrowers shall be deemed to have requested
         and Administrative Agent is hereby irrevocably authorized to fund such
         amount as a Base Rate Borrowing to the extent of availability under the
         Revolver Facility. If funds cannot be or are not advanced under the
         Revolver Facility to satisfy the obligations under the Swing Line
         Subfacility, Administrative Agent shall timely notify each Lender of
         such failure and of the date and amount not paid. No later than the
         close of business on the date such notice is given (if such notice was
         given prior to 12:00 noon, Dallas, Texas time on any Business Day, or,
         if made at any other time, on the next Business Day following the date
         of such notice), each Lender shall be deemed to have irrevocably and
         unconditionally purchased and received from Swing Line Lender an
         undivided interest and participation in such Swing Line Borrowing to
         the extent of such Lender's Pro Rata Part thereof, and each Lender
         shall make available to Swing Line Lender in immediately available
         funds such Lender's Pro Rata Part of the unpaid amount of such Swing
         Line Borrowing. All such amounts payable by any Lender shall include
         interest thereon from the date on which such payment is payable by such
         Lender to, but not including, the date such amount is paid by such
         Lender to Administrative Agent, at the Federal Funds Rate. If such
         Lender does not promptly pay such amount upon Administrative Agent's
         demand therefor, and until such time as such Lender makes the required
         payment, Swing Line Lender shall be deemed to continue to have
         outstanding a Swing Line Borrowing in the amount of such unpaid
         obligation. Each payment by Borrowers of all or any part of any Swing
         Line Borrowing shall be paid to Administrative Agent for the ratable
         benefit of Swing Line Lender and those Lenders who have funded their
         participations in such Swing Line Principal Debt under this SECTION
         2.3(b); provided that, with respect to any such participation, all
         interest accruing on the Swing Line Principal Debt to which such
         participation relates prior to the date of funding such participation
         shall be payable solely to Swing Line Lender for its own account. In
         the event that any payment received by the Swing Line Lender is
         required to be returned, each Lender will return to the Swing Line
         Lender any portion thereof previously distributed by the Swing Line
         Lender to it.

                  (c) Notwithstanding anything to the contrary in this
         Agreement, each Lender's obligation to fund the Borrowings and to
         purchase and fund participating interests pursuant to SECTION 2.3(b)
         shall be absolute and unconditional and shall not be affected by any
         circumstance, including, without limitation, (i) any setoff,
         counterclaim, recoupment, defense, or other Right which such Lender or
         any Borrower may have against the Swing Line Lender, any Borrower, or
         any other Person for any reason whatsoever; (ii) the occurrence or
         continuance of a Potential Default or a Default or the failure to
         satisfy any of the conditions specified in SECTION 7; (iii) any adverse
         change in the condition (financial or otherwise) of any Company; (iv)
         any breach of this Agreement by any Borrower, any Guarantor, or any
         Lender; or (v) any other circumstance, happening, or event whatsoever,
         whether or not similar to any of the foregoing.

         2.4 INCREASE IN REVOLVER COMMITMENT. So long as no Default or Potential
Default exists or arises as a result therefrom, Borrowers may from time to time
request any one or more Lenders to increase their respective Committed Sums or
request other financial institutions first approved by Administrative Agent
(such approval not to be unreasonably withheld or delayed) to agree to a
Committed Sum (in an aggregate amount of not less than $25,000,000 or such
lesser amount as may be available under the Maximum Revolver Commitment), so
that the Revolver Commitment may be increased to no more than the Maximum
Revolver Commitment. Any such increase of the Revolver


                                       21                  ACS CREDIT AGREEMENT
<PAGE>

Commitment must be effected by an amendment that is executed in accordance with
SECTION 13.10 by Borrowers, Administrative Agent, and the one or more Lenders
who have agreed to increase their Committed Sums or by new Lenders who have
agreed to new Committed Sums. No Lender is obligated to increase its Committed
Sum under any circumstances, and no Lender's Committed Sum may be increased
except by its execution of an amendment to this Agreement in accordance with
SECTION 13.10. Each new Lender providing such additional Committed Sum shall be
a "Lender" hereunder, entitled to the rights and benefits, and subject to the
duties, of a Lender under the Loan Documents. In such case, each Lender's
Commitment Percentage shall be recalculated to reflect the new proportionate
share of the revised Revolver Commitment and the Lender responsible for the
additional Committed Sum (the "PURCHASING LENDER") shall, immediately upon
receiving notice from Administrative Agent, pay to each Lender an amount equal
to its Pro Rata Part of the Principal Debt outstanding as of such date. All such
payments with respect to the Principal Debt shall reduce the outstanding
Principal Debt owed to each Lender receiving such payments and shall represent
advances under the Revolver Facility to Borrowers by the purchasing Lender; all
such payments with respect to funded participations under the Swing Line
Subfacility or LC Subfacility (as the case may be) shall reduce the applicable
participation of each Lender receiving such payment and shall represent the
purchase by the purchasing Lender of a participation under the Swing Line
Subfacility or the LC Subfacility (as the case may be). The purchasing Lender
shall be entitled to share ratably in interest accruing on the balances
purchased, at the rates provided herein for such balances, from and after the
date of purchase. All new Borrowings under the Revolver Facility occurring after
an increase of the Revolver Commitment shall be funded in accordance with the
Lender's revised Commitment Percentages.

         2.5 TERMINATIONS OR REDUCTIONS OF COMMITMENTS.

                  (a) Voluntary Commitment Reduction. Without premium or
         penalty, and upon giving not less than five Business Days prior written
         and irrevocable notice to Administrative Agent, Borrowers may terminate
         in whole or in part the unused portion of the Revolver Commitment, the
         Swing Line Commitment, or the commitment under the LC Subfacility;
         provided that: (i) each partial termination of the Revolver Commitment
         shall be in an amount of not less than $25,000,000 or a greater
         integral multiple of $5,000,000; each partial termination of the Swing
         Line Commitment or the commitment under the LC Subfacility shall be in
         an amount of not less than $5,000,000 or a greater integral multiple of
         $1,000,000; and (ii) on any date of determination, the amount of the
         Revolver Commitment may not be reduced below the Revolver Commitment
         Usage, the Swing Line Commitment may not be reduced below the Swing
         Line Principal Debt, and the commitment under the LC Subfacility may
         not be reduced below the LC Exposure unless the mandatory prepayment
         required by SECTION 3.3(b) (if any) is made contemporaneously with such
         reduction. At the time of any commitment termination under this SECTION
         2.5, Borrowers shall pay to Administrative Agent, for the account of
         each Lender, any amounts that may then be due under SECTION 3.3(b), all
         accrued and unpaid fees then due and payable under this Agreement, the
         interest attributable to the amount of that reduction, and any related
         Consequential Loss. Any part of the Revolver Commitment, the Swing Line
         Commitment, or the commitment under the LC Subfacility that is
         terminated may not be reinstated.

                  (b) Additional Reductions. The Swing Line Commitment and the
         commitment under the LC Subfacility shall each be reduced from time to
         time on the date of any voluntary reduction of the Revolver Commitment
         by the amount, if any, by which each such Subfacility exceeds the
         Revolver Commitment after giving effect to such reduction of the
         Revolver Commitment.


                                       22                  ACS CREDIT AGREEMENT
<PAGE>

                  (c) Ratable Allocation of Revolver Commitment Reductions. Each
         reduction of the Revolver Commitment under this SECTION 2.5 shall be
         allocated among the Lenders in accordance with their respective
         Commitment Percentages.

         2.6 BORROWING PROCEDURE. The following procedures apply to all
Borrowings (other than Swing Line Borrowings and Borrowings pursuant to SECTIONS
2.2(c) or 2.3(b)):

                  (a) Borrowing Request. Any Borrower may request a Borrowing by
         making or delivering a Borrowing Notice to Administrative Agent
         requesting that Lenders fund a Borrowing on a certain date (the
         "BORROWING DATE"), which Borrowing Notice (i) shall be irrevocable and
         binding on Borrowers, (ii) must specify the Borrower or Borrowers which
         are to receive all or any portion of such Borrowing and the amount of
         such Borrowing to be advanced to such Borrower or Borrowers, (iii)
         shall specify the Borrowing Date, amount, Type, and (for a Borrowing
         comprised of Eurodollar Rate Borrowings) Interest Period, (iv) must be
         signed by the requesting Borrower and concurred to by each other
         Borrower, and (v) must be received by Administrative Agent no later
         than 12:00 p.m. Dallas, Texas time on the third Business Day preceding
         the Borrowing Date for any Eurodollar Rate Borrowing or 12:00 p.m.,
         Dallas, Texas time on the Business Day preceding the Borrowing Date for
         any Base Rate Borrowing. Administrative Agent shall timely notify each
         Lender with respect to each Borrowing Notice.

                  (b) Funding. Each Lender shall remit its Commitment Percentage
         of each requested Borrowing to Administrative Agent's principal office
         in Dallas, Texas, in funds which are or will be available for immediate
         use by Administrative Agent by 1:00 p.m. Dallas, Texas time on the
         applicable Borrowing Date. Subject to receipt of such funds,
         Administrative Agent shall (unless to its actual knowledge any of the
         conditions precedent therefor have not been satisfied by Borrowers or
         waived by the requisite Lenders under SECTION 13.10) make such funds
         available to Borrowers on the Borrowing Date by causing such funds to
         be deposited to the account designated to Administrative Agent by
         Borrowers.

                  (c) Funding Assumed. Absent contrary written notice from a
         Lender by 1:00 p.m. Dallas, Texas time on the applicable Borrowing
         Date, Administrative Agent may assume that each Lender has made its
         Commitment Percentage of the requested Borrowing available to
         Administrative Agent on the applicable Borrowing Date, and
         Administrative Agent may, in reliance upon such assumption (but shall
         not be required to), make available to Borrowers a corresponding
         amount. If a Lender fails to make its Commitment Percentage of any
         requested Borrowing available to Administrative Agent on the applicable
         Borrowing Date, 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
         Administrative Agent recovers the amount from that Lender, at an annual
         interest rate equal to the Federal Funds Rate, or (ii) if that Lender
         fails to pay its amount upon demand, then from Borrowers and, to the
         extent of availability under the Swing Line Subfacility, Borrowers
         shall be deemed to have requested and Swing Line Lender is hereby
         irrevocably authorized to fund any amounts due from Borrowers pursuant
         to this SECTION 2.6(c) as a Swing Line Borrowing. No Lender is
         responsible for the failure of any other Lender to make its Commitment
         Percentage of any Borrowing available as required by SECTION 2.6(b);
         however, failure of any Lender to make its Commitment Percentage of any
         Borrowing so available does not excuse any other Lender from making its
         Commitment Percentage of any Borrowing so available.

SECTION 3 TERMS OF PAYMENT.

         3.1 LOAN ACCOUNTS, NOTES, AND PAYMENTS.

                  (a) Loan Accounts; Noteless Transaction. Borrowers shall be
         jointly and severally liable for the Principal Debt, which Principal
         Debt owed to each Lender shall be evidenced by one or more Loan
         Accounts or records maintained by such Lender in the ordinary course of
         business. The Loan Accounts or records maintained by Administrative
         Agent (including, without limitation, the Register) and each Lender
         shall be prima facie evidence absent manifest error of the amount of
         the Borrowings made by Borrowers from each Lender under this Agreement
         and the interest and principal payments thereon. Any failure to so
         record or any error in doing so shall not, however, limit or otherwise
         affect the obligation of Borrowers under the Loan Documents to pay any
         amount owing with respect to the Obligation.

                  (b) Notes. Upon the request of any Lender, made through
         Administrative Agent, the Principal Debt owed to such Lender may be
         evidenced by one or more of the following Notes (as the case may be):
         (i) a Revolver Note and (ii) a Swing Line Note (with respect to the
         Swing Line Lender only). In the event Notes are requested by any Lender
         and upon the addition of or release of any Borrower (as contemplated by
         SECTIONS 6.1 and 6.2), the then-existing Borrowers (after giving effect
         to any such addition or release) shall promptly prepare, execute, and
         deliver to each requesting Lender Notes payable to the order of such
         Lender.

                  (c) Payment. Other than the LC fees payable directly to LC
         Issuers pursuant to SECTION 5.5(b), all payments of principal,
         interest, and other amounts to be made by Borrowers under this
         Agreement and the other Loan Documents shall be made to Administrative
         Agent at its principal office in Dallas, Texas in Dollars and in funds
         which are or will be available for immediate use by Administrative
         Agent by 12:00 noon Dallas, Texas time on the day due, without setoff,
         deduction, or counterclaim. Payments made after 12:00 noon, Dallas,
         Texas, time shall be deemed made on the Business Day next following.
         Administrative Agent shall pay to each Lender any payment of principal,
         interest, or other amount to which such Lender is entitled hereunder on
         the same day Administrative Agent shall have received the same from
         Borrowers; provided such payment is received by Administrative Agent
         prior to 12:00 noon, Dallas, Texas time, and otherwise before 12:00
         noon Dallas, Texas time on the Business Day next following.

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

         3.2 INTEREST AND PRINCIPAL PAYMENTS.

                  (a) Interest. Accrued interest on each Eurodollar Rate
         Borrowing is due and payable on the last day of its respective Interest
         Period, on the date of any prepayment set forth in SECTION 3.3, and on
         the Termination Date; provided that, if any Interest Period is greater
         than three months, then accrued interest is also due and payable on the
         three month anniversary of the date on which such Interest Period
         commences and on each three month anniversary thereafter, as well as on
         the last day of such Interest Period. Accrued interest on each Base
         Rate Borrowing


                                       24                  ACS CREDIT AGREEMENT
<PAGE>

         shall be due and payable on the 10th Business Day of each of January,
         April, July, and October and on the Termination Date.

                  (b) Principal Debt. The Principal Debt is due and payable on
         the Termination Date.

         3.3 PREPAYMENTS.

                  (a) Optional Prepayments. Except as set forth herein, after
         giving Administrative Agent advance written notice of the intent to
         prepay, Borrowers may voluntarily prepay all or any part of the
         Principal Debt or the Swing Line Principal Debt, from time to time and
         at any time, in whole or in part, without premium or penalty; provided
         that: (i) such notice must be received by Administrative Agent by 12:00
         noon, Dallas, Texas time, one Business Day preceding the date of
         prepayment of any Borrowing except with respect to the Swing Line
         Principal Debt for which same Business Day notice is sufficient; (ii)
         each such partial prepayment must be in a minimum amount of at least
         $1,000,000 or a greater integral multiple of $1,000,000 thereof or such
         lesser amount as may be outstanding under the Revolver Facility (or
         with respect to prepayments of the Swing Line Principal Debt, $100,000
         or a greater integral multiple thereof or such lesser amount as may be
         outstanding under the Swing Line Subfacility); (iii) any Eurodollar
         Rate Borrowing may only be prepaid at the end of an applicable Interest
         Period (unless Borrowers pay the amount of any Consequential Loss); and
         (iv) Borrowers shall pay any related Consequential Loss within ten (10)
         days after demand therefor. Conversions under SECTION 3.11 are not
         prepayments. Each notice of prepayment shall specify the prepayment
         date, the applicable loan hereunder of Principal Debt being prepaid,
         and the Type of Borrowing(s) and amount(s) of such Borrowing(s) to be
         prepaid and shall constitute a binding obligation of Borrowers to make
         a prepayment on the date stated therein, together with (unless such
         prepayment is made with respect to a Base Rate Borrowing or Swing Line
         Borrowing) accrued and unpaid interest to the date of such payment on
         the aggregate principal amount prepaid. Unless a Default or Potential
         Default has occurred and is continuing (or would arise as a result
         thereof), any payment or prepayment of the Principal Debt may be
         reborrowed by Borrowers, subject to the terms and conditions of the
         Loan Documents.

                  (b) Revolver Facility Mandatory Payments/Reductions. On any
         date of determination (i) if the Revolver Commitment Usage exceeds the
         Revolver Commitment then in effect, or the Swing Line Principal Debt
         exceeds the Swing Line Commitment then in effect, then Borrowers shall
         make a mandatory prepayment of the Principal Debt or the Swing Line
         Principal Debt, as the case may be, in at least the amount of such
         excess, together with (x) all accrued and unpaid interest on the
         principal amount so prepaid and (y) any Consequential Loss arising as a
         result thereof; provided that, on any such reduction date, if no Swing
         Line Principal Debt or Principal Debt is then outstanding, but the LC
         Exposure exceeds the Revolver Commitment, then Borrowers shall provide
         to Administrative Agent, for the benefit of Lenders, cash collateral in
         Dollars in an amount at least equal to 100% of such excess.

                  (c) Mandatory Prepayments of Interest/Consequential Loss. All
         prepayments under SECTION 3.3 shall be made, together with accrued
         interest to the date of such prepayment on the principal amount
         prepaid, together with any Consequential Loss arising as a result
         thereof.

         3.4 INTEREST OPTIONS. Except that the Eurodollar Rate may not be
selected when a Default or Potential Default exists and except as otherwise
provided in this Agreement, Borrowings bear interest at a rate per annum equal
to the lesser of (a) as to the respective Type of Borrowing (as designated by
Borrowers in accordance with this Agreement), the Adjusted Eurodollar Rate plus
the Applicable Margin for Eurodollar Rate Borrowings or the Base Rate, and (b)
the Maximum Rate. Each change in the Base Rate or the Maximum Rate, subject to
the terms of this Agreement, will become effective, without notice to any
Borrower or any other Person, upon the effective date of such change.


                                       25                  ACS CREDIT AGREEMENT
<PAGE>

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

         3.6 DEFAULT RATE. At the option of Required Lenders and to the extent
permitted by Law all past-due amounts of the Obligation shall bear interest from
maturity (whether stated or by acceleration) at the Default Rate until paid,
regardless whether such payment is made before or after entry of a judgment;
provided that, the Default Rate shall automatically apply to the extent
specified in and on the terms of SECTIONS 2.2(c), 2.3(a), and 11.3.

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

         3.8 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 in the case
of an Eurodollar Rate Borrowing (unless the calculation would result in an
interest rate greater than the Maximum Rate, in which event interest will be
calculated on the basis of a year of 365 or 366 days, as the case may be) and
365 or 366 days, as the case may be, in the case of a Base Rate Borrowing. All
interest rate determinations and calculations by Administrative Agent are
conclusive and binding absent manifest error.

         3.9 MAXIMUM RATE. Regardless of any provision contained in any Loan
Document, neither Administrative Agent nor any Lender shall ever be 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
Lenders ever do so, then such excess shall be deemed a partial prepayment of
principal and treated hereunder as such and any remaining excess shall be
refunded to Borrowers. In determining if the interest paid or payable exceeds
the Maximum Rate, Borrowers and Lenders shall, to the maximum extent permitted
under applicable Law, (a) treat all Borrowings as but a single extension of
credit (and Lenders and Borrowers agree that such is the case and that provision
herein for multiple Borrowings is for convenience only), (b) characterize any
nonprincipal payment as an expense, fee, or premium rather than as interest, (c)
exclude voluntary prepayments and the effects thereof, and (d) amortize,
prorate, allocate, and spread the total amount of interest throughout the entire
contemplated term of the Obligation. However, if the Obligation is paid and
performed in full prior to the end of the full contemplated term thereof, and if
the interest received for the actual period of existence thereof exceeds the
Maximum Amount, Lenders shall refund such excess, and, in such event, Lenders
shall not, to the extent permitted by Law, be subject to any penalties provided
by any Laws for contracting for, charging, taking, reserving, or receiving
interest in excess of the Maximum Amount. 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, as amended. Each


                                       26                  ACS CREDIT AGREEMENT
<PAGE>

Borrower agrees that Chapter 346 of the Texas Finance Code, as amended (which
regulates certain revolving credit loan accounts and revolving tri-party
accounts), does not apply to the Obligation.

         3.10 INTEREST PERIODS. When Borrowers request any Eurodollar Rate
Borrowing, Borrowers may elect the interest period (each an "INTEREST PERIOD")
applicable thereto, which shall be, at Borrowers' option and subject to
availability, one, two, three, or six months; provided, however, that: (a) the
initial Interest Period for a Eurodollar Rate Borrowing shall commence on the
date of such Borrowing (including the date of any conversion thereto), and each
Interest Period occurring thereafter in respect of such Borrowing shall commence
on the day on which the next preceding Interest Period applicable thereto
expires; (b) if any Interest Period for a Eurodollar Rate Borrowing begins on a
day for which there is no numerically corresponding Business Day in the calendar
month at the end of such Interest Period, such Interest Period shall end on the
next Business Day immediately following what otherwise would have been such
numerically corresponding day in the calendar month at the end of such Interest
Period (unless such date would be in a different calendar month from what would
have been the month at the end of such Interest Period, or unless there is no
numerically corresponding day in the calendar month at the end of the Interest
Period; whereupon, such Interest Period shall end on the last Business Day in
the calendar month at the end of such Interest Period); and (c) no Interest
Period may be chosen with respect to any portion of the Principal Debt which
would extend beyond the scheduled repayment date (including any dates on which
mandatory prepayments are required to be made) for such portion of the Principal
Debt.

         3.11 CONVERSIONS. Borrowers may (a) convert a Eurodollar Rate 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 Eurodollar Rate Borrowing, and
(c) elect a new Interest Period (in the case of a Eurodollar Rate Borrowing), by
giving a Conversion Notice of such intent to Administrative Agent no later than
12:00 p.m. Dallas, Texas time on the third Business Day prior to the date of
conversion or the last day of the Interest Period, as the case may be (in the
case of a conversion to a Eurodollar Rate Borrowing or an election of a new
Interest Period), and no later than 12:00 p.m. Dallas, Texas time one Business
Day prior to the last day of the Interest Period (in the case of a conversion to
a Base Rate Borrowing); provided that, the principal amount converted to, or
continued as, a Eurodollar Rate Borrowing shall be in an amount not less than
$5,000,000 or a greater integral multiple of $1,000,000 (or such lesser amount
as may be outstanding). Administrative Agent shall timely notify each Lender
with respect to each Conversion Notice. Absent Borrowers' Conversion Notice or
election of a new Interest Period, a Eurodollar Rate Borrowing shall be deemed
converted to a Base Rate Borrowing effective as of the expiration of the
Interest Period applicable thereto. No Eurodollar Rate Borrowing may be either
made or continued as a Eurodollar Rate Borrowing, and no Base Rate Borrowing may
be converted to a Eurodollar Rate Borrowing, if the interest rate for such
Eurodollar Rate Borrowing would exceed the Maximum Rate. The right to convert
from a Base Rate Borrowing to a Eurodollar Rate Borrowing, or to continue as a
Eurodollar Rate Borrowing shall not be available during the occurrence of a
Default or Potential Default.

         3.12 ORDER OF APPLICATION.

                  (a) No Default. If no Default or Potential Default exists and
         if no order of application is otherwise specified in the Loan
         Documents, payments and prepayments of the Obligation shall be applied
         first to fees, second to accrued interest then due and payable on the
         Principal Debt, and then to the remaining Obligation in the order and
         manner as Borrowers may direct.

                  (b) Default. If a Default or Potential Default exists (or if
         Borrowers fail to give directions as permitted under SECTION 3.12(a)),
         any payment or prepayment (including proceeds from the exercise of any
         Rights) shall be applied to the Obligation in the following order: (i)
         to the ratable payment of all fees, expenses, and indemnities for which
         Agents or Lenders have not been paid or reimbursed in accordance with
         the Loan Documents (as used in this


                                       27                  ACS CREDIT AGREEMENT
<PAGE>

         SECTION 3.12(b)(i), a "ratable payment" for any Lender or any Agent
         shall be, on any date of determination, that proportion which the
         portion of the total fees, expenses, and indemnities owed to such
         Lender or such Agent bears to the total aggregate fees and indemnities
         owed to all Lenders and Agents on such date of determination); (ii) to
         the ratable payment of accrued and unpaid interest on the Principal
         Debt (as used in this SECTION 3.12(b)(ii), "ratable payment" means, for
         any Lender, on any date of determination, that proportion which the
         accrued and unpaid interest on the Principal Debt owed to such Lender
         bears to the total accrued and unpaid interest on the Principal Debt
         owed to all Lenders); (iii) to the ratable payment of the Swing Line
         Principal Debt which is due and payable and which remains unfunded by
         any Borrowing; provided that, such payments shall be allocated ratably
         among the Swing Line Lender and the Lenders which have funded their
         participations in the Swing Line Principal Debt (as used in this
         SECTION 3.12(b)(iii), "ratable payment" and "ratably" means for Swing
         Line Lender and any Lender, on any date of determination, that
         proportion which the Swing Line Principal Debt owed (whether directly
         or by participations) to Swing Line Lender or such Lender (as
         applicable) bears to the Swing Line Principal Debt owed to the Swing
         Line Lender and all Lenders); (iv) to the ratable payment of any
         reimbursement obligation with respect to any LC issued pursuant to the
         Agreement which is due and payable and which remains unfunded by any
         Borrowing; provided that, such payments shall be allocated ratably
         among the applicable LC Issuer and the Lenders which have funded their
         participations in such LC (as used in this SECTION 3.12(b)(iv),
         "ratable payment" and "ratably" means for any LC Issuer and any Lender,
         on any date of determination, that proportion which the reimbursement
         obligation under such LC owed (whether directly or by participations)
         to such LC Issuer or Lender (as applicable) bears to the reimbursement
         obligation under such LC owed to the applicable LC Issuer and all
         Lenders); (v) to the ratable payment of the remaining Principal Debt
         (as used in this SECTION 3.12(b)(v), "ratable payment" means for any
         Lender, on any date of determination, that proportion which the
         Principal Debt owed to such Lender bears to the Principal Debt owed to
         all Lenders); (vi) to provide cash collateral in an amount equal to
         100% of the LC Exposure then existing in accordance with SECTION
         2.2(g); and (vii) to the payment of the remaining Obligation in the
         order and manner Required Lenders deem appropriate.

Subject to the provisions of SECTION 12 and provided that Administrative Agent
shall not in any event be bound to inquire into or to determine the validity,
scope, or priority of any interest or entitlement of any Lender and may suspend
all payments or seek appropriate relief (including, without limitation,
instructions from Required Lenders or an action in the nature of interpleader)
in the event of any doubt or dispute as to any apportionment or distribution
contemplated hereby, Administrative Agent shall promptly distribute such amounts
to each Lender in accordance with the Agreement and the related Loan Documents.

         3.13 SHARING OF PAYMENTS, ETC. If any Lender shall obtain 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 3.14) which is in excess of its share of any such payment in
accordance with the relevant Rights of the Lenders under the Loan Documents,
then such Lender shall purchase from the other Lenders such participations as
shall be necessary to cause such purchasing Lender to share the excess payment
with each other Lender in accordance with the relevant Rights under the Loan
Documents. If all or any portion of such excess payment is subsequently
recovered from such purchasing Lender, then the purchase shall be rescinded and
the purchase price restored to the extent of such recovery. Borrowers agree that
any Lender purchasing a participation from another Lender pursuant to this
SECTION 3.13 may, to the fullest extent permitted by Law, exercise all of its
Rights of payment (including the Right of offset) with respect to such
participation as fully as if such Lender were the direct creditor of each
Borrower in the amount of such participation.


                                       28                  ACS CREDIT AGREEMENT
<PAGE>

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

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

SECTION 4 CHANGE IN CIRCUMSTANCES.

         4.1 INCREASED COST AND REDUCED RETURN.

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

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

                           (ii) shall impose, modify, or deem applicable any
                  reserve, special deposit, assessment, or similar requirement
                  (other than the Reserve Requirement utilized in the
                  determination of the Adjusted Eurodollar Rate) relating to any
                  extensions of credit or other assets of, or any deposits with
                  or other liabilities or commitments of, such Lender (or its
                  Applicable Lending Office), including the commitment of such
                  Lender hereunder; or

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

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

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

                  (c) Changes in Applicable Lending Office. Compensation
         Statement. Each Lender shall promptly (and in any event with eighteen
         (18) months) notify Borrowers and Administrative Agent of any event of
         which it has knowledge, occurring after the date hereof, which will
         entitle such Lender to compensation pursuant to this Section and will
         designate a different Applicable Lending Office if such designation
         will avoid the need for, or reduce the amount of, such compensation and
         will not, in the judgment of such Lender, be otherwise disadvantageous
         to it. Any Lender claiming compensation under this Section shall
         furnish to Borrowers and Administrative Agent a statement setting forth
         the additional amount or amounts to be paid to it hereunder which shall
         be conclusive in the absence of manifest error. In determining such
         amount, such Lender may use any reasonable averaging and attribution
         methods. In no event will Borrowers be obligated to compensate any
         Lender pursuant to this SECTION 4.1 for any amounts described herein
         that accrued more than eighteen (18) months prior to the date the
         notice described above is given by the party requesting such
         compensation, but the foregoing shall in no way limit the right of such
         Lender to request compensation for amounts accrued during such eighteen
         (18) month period or any future period.

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

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

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

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

         4.3 ILLEGALITY. Notwithstanding any other provision of the Loan
Documents, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to make, maintain, or fund Eurodollar Rate Borrowings
hereunder, then such Lender shall promptly notify Borrowers thereof and


                                       30                  ACS CREDIT AGREEMENT
<PAGE>

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

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

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

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

If such Lender gives notice to Borrowers (with a copy to Administrative Agent)
that the circumstances specified in SECTIONS 4.1, 4.2, or 4.3 hereof that gave
rise to the conversion of such Lender's Eurodollar Rate Borrowings pursuant to
this SECTION 4.4 no longer exist (which such Lender agrees to do promptly upon
such circumstances ceasing to exist) at a time when Eurodollar Rate Borrowings
made by other Lenders are outstanding, such Lender's Base Rate Borrowings shall
be automatically converted, on the first day(s) of the next succeeding Interest
Period(s) for such outstanding Eurodollar Rate Borrowings, to the extent
necessary so that, after giving effect thereto, all Eurodollar Rate Borrowings
held by the Lenders and by such Lender are held pro rata (as to principal
amounts, Types, and Interest Periods) in accordance with their respective
Committed Sums.

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

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

                  (b) any failure by Borrowers for any reason (including,
         without limitation, the failure of any condition precedent specified in
         SECTION 7.2 to be satisfied) to borrow, convert, continue, or prepay a
         Eurodollar Rate Borrowing on the date for such borrowing, conversion,
         continuation, or prepayment specified in the relevant Borrowing Notice,
         prepayment, continuation, or conversion under this Agreement.

         4.6 TAXES.

                  (a) General. Any and all payments by Borrowers to or for the
         account of any LC Issuer, Lender, or Administrative Agent 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,

                                       31                  ACS CREDIT AGREEMENT

<PAGE>

         in the case of each LC Issuer, Lender, and Administrative Agent, Taxes
         imposed on its income and franchise Taxes imposed on it by the
         jurisdiction under the laws of which such LC Issuer, Lender (or its
         Applicable Lending Office), or Administrative Agent (as the case may
         be) is organized, or any political subdivision thereof. If Borrowers
         shall be required by law to deduct any Taxes from or in respect of any
         sum payable under any Loan Document to any LC Issuer, Lender, or
         Administrative Agent, (i) the sum payable shall be increased as
         necessary so that after making all required deductions (including
         deductions applicable to additional sums payable under this SECTION
         4.6) such LC Issuer, Lender, or Administrative Agent receives an amount
         equal to the sum it would have received had no such deductions been
         made, (ii) Borrowers shall make such deductions, (iii) Borrowers shall
         pay the full amount deducted to the relevant taxation authority or
         other authority in accordance with applicable law, and (iv) Borrowers
         shall furnish to Administrative Agent, at its address listed in
         SCHEDULE 2.1, the original or a certified copy of a receipt evidencing
         payment thereof.

                  (b) Stamp and Documentary Taxes. In addition, Borrowers
         (jointly and severally) agree 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 any
         Loan Document or from the execution or delivery of, or otherwise with
         respect to, any Loan Document (hereinafter referred to as "OTHER
         TAXES").

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

                  (d) Withholding Tax Forms. Each Lender organized under the
         Laws of a jurisdiction outside the United States, on or prior to the
         Closing Date 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 Borrowers or Administrative Agent (but only so
         long as such Lender remains lawfully able to do so), shall provide
         Borrowers and Administrative Agent with (i) two duly completed copies
         of Internal Revenue Service Form W-BEN, W-8ECI, W-8IMY, W-9, or other
         applicable form, as the case may be, certifying in each case 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, or certifying that such Lender is
         entitled to an exemption from or a reduced rate of tax on payment
         pursuant to the "portfolio interest" exception under section 871(h) or
         881(c) of the Code, (ii) if applicable, a statement indicating that
         such Holder is entitled to the "portfolio interest" exception under
         Section 871(h) or 881(c)(3) of the Code, and (iii) any other
         governmental forms or certificates which are necessary or required
         under an applicable tax treaty or otherwise by Law to reduce or
         eliminate withholding tax, which has been reasonably requested by
         Borrowers or Administrative Agent. If an event (including without
         limitation any change in treaty, Law, or regulation) occurs after the
         date hereof which renders all such forms inapplicable or which would
         prevent any Lender from duly completing and delivering any such form
         with respect to it and such Lender advises Borrowers and Administrative
         Agent that it is not capable of receiving payments without any
         deduction or withholding of United States federal income tax, such
         Lender shall not be required to deliver such forms.


                                       32                  ACS CREDIT AGREEMENT
<PAGE>


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

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

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

                  (h) Survival. Without prejudice to the survival of any other
         agreement of Borrowers hereunder, the agreements and obligations of
         Borrowers contained in this SECTION 4.6 shall survive for eighteen (18)
         months after termination of the Revolver Commitment and the payment in
         full of the Obligation.

         4.7 REMOVAL OF LENDERS. If (a) a Lender or a Participant requests
compensation pursuant to SECTIONS 4.1 or 4.6 and the Required Lenders are not
also doing the same, or (b) the obligation of a Lender to make Eurodollar Rate
Borrowings or to continue, or to convert Borrowings into Eurodollar Rate
Borrowings shall be suspended pursuant to SECTION 4.1 or SECTION 4.3, but the
obligation of the Required Lenders shall not have been suspended under such
Sections, Borrowers may either (i) demand that such Lender or Participant (the
"AFFECTED LENDER"), and upon such demand the Affected Lender shall promptly,
assign its Revolver Commitment and all of its Principal Debt to an Eligible
Assignee subject to and in accordance with the provisions of SECTION 13.12(b)
for a purchase price equal to the aggregate principal balance of Principal Debt
then owing to the Affected Lender (together with any participation held by the
Affected Lender in any Swing Line Principal Debt pursuant to SECTION 2.3(b) or
in any LC and related reimbursement obligations under the LC Subfacility
pursuant to SECTION 2.2(b)) plus any accrued but unpaid interest thereon,
accrued but unpaid fees owing to the Affected Lender, and any amounts owing the
Affected Lender under SECTION 4, or (ii) pay to the Affected Lender the
aggregate principal balance of Principal Debt (together with any participation
held by the Affected Lender in any Swing Line Loan pursuant to SECTION 2.3(b) or
in any LC and related reimbursement obligations under the LC Subfacility
pursuant to SECTION 2.2(b)) then owing to the Affected Lender plus any accrued
but unpaid interest thereon, accrued but unpaid fees owing to the Affected
Lender, and any amounts owing the Affected Lender under SECTION 4, whereupon the
Affected Lender shall no longer be a party hereto or have any rights or
obligations hereunder or under any of the other Loan Documents, subject to the
survival of certain provisions as set forth in SECTION 13.13. Each of
Administrative Agent and the Affected Lender shall reasonably cooperate in
effectuating the replacement of an Affected Lender under this Section, but at no
time shall Administrative Agent, the Affected Lender, or any other Lender be
obligated in any way whatsoever to initiate any such replacement or to assist in
finding an Eligible Assignee. The exercise by Borrowers of the rights under this
Section shall be at Borrowers' sole cost and expenses and at no cost or expense
to Administrative Agent, the Affected Lender, or any of the other Lenders and
shall not be available if any Default or Potential Default has occurred and is
continuing. The


                                       33                  ACS CREDIT AGREEMENT

<PAGE>

terms of this Section shall not in any way limit Borrowers' obligation to pay to
any Affected Lender compensation owing to such Affected Lender pursuant to
SECTION 4.

SECTION 5 FEES.

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

         5.2 FEES OF ADMINISTRATIVE AGENT AND ARRANGER. Borrowers shall pay to
Administrative Agent and Arranger, as the case may be, solely for their
respective accounts, the fees described in that certain separate letter
agreement dated as of August 7, 2002, between ACS, Administrative Agent, and
Arranger.

         5.3 FACILITY FEE. Borrowers shall pay to the Administrative Agent for
the account of each Lender, in accordance with its Commitment Percentage, a
facility fee (the "FACILITY FEE") equal to the Applicable Margin for Facility
Fee (applied on a per diem basis) times the actual daily amount of the Revolver
Commitment, regardless of usage (or if the Revolver Commitment has been
terminated, such Lender's Pro Rata Part calculated on the Principal Debt). The
Facility Fee shall accrue at all times from the Closing Date until the date the
Principal Debt has been paid in full and the Revolver Commitment has been
terminated and shall be due and payable on the 10th Business Day of each
January, April, July, and October, commencing with the first such date to occur
after the Closing Date, and ending on the date both the Principal Debt has been
paid in full and the Revolver Commitment has been terminated for the amount
accrued during the previous fiscal quarterly period. The Facility Fee shall be
calculated for the amount accrued during the previous fiscal quarterly period,
in accordance with SECTION 5.1(f), and if there is any change in the Applicable
Margin during any quarter, the actual daily amount shall be computed and
multiplied by the Applicable Margin for Facility Fees (on a per diem basis)
separately for each period during such quarter that such Applicable Margin was
in effect. The Facility Fee shall accrue at all times, including at any time
during which one or more of the conditions in SECTION 7.2 is not met.

         5.4 UTILIZATION FEE. Borrowers shall pay to the Administrative Agent
for the account of each Lender, in accordance with its Commitment Percentage, a
utilization fee (the "UTILIZATION FEE") equal to the Applicable Margin for
Utilization Fee (applied on a per diem basis) times the actual daily aggregate
Revolver Commitment Usage; provided that (i) on and after March __, 2003, but
prior to the Termination Date, the Utilization Fee shall be payable only in
respect of each day that such aggregate Revolver Commitment Usage exceeds 50% of
the Revolver Commitment then in effect, and (ii) on and after the Termination
Date, the Utilization Fee shall be payable only in respect of each day that such
aggregate Revolver Commitment Usage exceeds 50% of the Revolver Commitment that
was in existence on the Business Day immediately prior to the termination of the
Revolver Commitment. The Utilization Fee shall be due and payable on the 10th
Business Day of each January, April, July and October, commencing with the first
such date to occur after the Closing Date, and ending on the date both the
Principal Debt has been paid in full and the Revolver Commitment has been
terminated for the amount accrued during the previous fiscal quarterly period.
The Utilization Fee shall be calculated for the amount accrued during the
previous fiscal quarterly period in accordance with SECTION 5.1(f), and if there
is any change in the Applicable Margin during any quarter, the actual daily
amount shall be computed and multiplied by the Applicable Margin for Utilization
Fee (on a per diem basis) separately for each period during such quarter


                                       34                  ACS CREDIT AGREEMENT
<PAGE>

that such Applicable Margin was in effect. The Utilization Fee shall accrue at
all times, including at any time during which one or more of the conditions in
SECTION 7.2 is not met.

         5.5 LC FEES. As an inducement for the issuance (including, without
limitation, any extension) of each LC, Borrowers (jointly and severally) agree
to pay:

                  (a) To Administrative Agent, for the account of each Lender,
         according to each Lender's Commitment Percentage on the day the fee is
         payable, a LC issuance fee payable for the amount accrued during the
         previous fiscal quarterly period, on the 10th Business Day of each
         January, April, July, and October, and on the expiry date of the LC for
         the amount accrued during the previous fiscal quarterly period. The
         issuance fee for each LC or any extension thereof shall be in an amount
         equal to the product of (a) the Applicable Margin for Eurodollar Rate
         Borrowings in effect on the date of payment of such fee (calculated on
         a per annum basis) multiplied by (b) the average Dollar Equivalent of
         the stated amount of such LC during the period of determination.

                  (b) To the applicable LC Issuer, solely for its individual
         account, and in addition to such LC Issuer's ratable portion of the LC
         issuance fees payable pursuant to SECTION 5.5(a), a fronting fee of
         0.125% of the Dollar Equivalent of the face amount of such LC (or
         extensions thereof) payable on the date of issuance of any LC by such
         LC Issuer (or any extension thereof). In addition, Borrowers shall pay
         to the applicable LC Issuer, solely for its individual account,
         standard administrative charges for LC amendments.

SECTION 6. SECURITY; GUARANTIES.

         6.1 BORROWERS, GUARANTIES, AND FOREIGN STOCK PLEDGES. Borrowers agree
that, at all times (subject to the grace periods set forth in the last sentence
of this SECTION 6.1), the sum of: (a) the EBITDA of ACS, plus (b) the EBITDA of
all then-existing Domestic Subsidiary Obligors, plus (c) the EBITDA of all
Pledged Foreign Subsidiaries, plus (d) at the option of Borrowers as reflected
on the most recent certificate demonstrating compliance with the Coverage
Requirement, the EBITDA of any Included Foreign Subsidiaries, shall equal or
exceed 65% of the consolidated EBITDA of the Companies (such requirement
referred to herein as the "COVERAGE REQUIREMENT"). ACS shall, within the time
periods required below, add a Domestic Subsidiary Obligor as a Guarantor or
Borrower or deliver a Foreign Stock Pledge from a Domestic Subsidiary in order
to satisfy the Coverage Requirement by complying with the conditions precedent
set forth in SECTION 7.3. For purposes of the Coverage Requirement calculation,
EBITDA shall be calculated (i) for the applicable Company on an unconsolidated
basis without giving effect to the EBITDA of any Subsidiaries of such Company
and (ii) based on the most recently ended Rolling Period for which Financial
Statements have been delivered. If any Compliance Certificate delivered pursuant
to SECTION 9.3 or any other certificate requested by Administrative Agent with
respect to compliance with this SECTION 6.1 indicates that the Coverage
Requirement is not satisfied, then Borrowers shall have up to (y) 20 days from
the date of delivery of such Compliance Certificate or other certificate to add
additional Borrowers or Guarantors or (z) 45 days to deliver additional Foreign
Stock Pledges, such that after giving effect to such additional Borrowers,
Guarantors, and Foreign Stock Pledges, the Coverage Requirement is satisfied.

         6.2 RELEASE OF BORROWERS, GUARANTIES, AND COLLATERAL. Upon delivery of
a proforma Compliance Certificate demonstrating and certifying to Administrative
Agent that no Default or Potential Default exists or will exist immediately
after (i) subtracting the EBITDA of any Borrower or Guarantor that is to be
released, or any Pledged Foreign Subsidiary whose Stock is to be released, from
the calculation of the Coverage Requirement and (ii) adding the EBITDA of any
additional Borrowers or Guarantors being provided concurrently therewith, plus
the EBITDA of any Foreign Subsidiaries whose Stock is pledged (and, at the
option of the Borrowers, any Included Foreign Subsidiaries) concurrently


                                       35                  ACS CREDIT AGREEMENT
<PAGE>

therewith, Administrative Agent shall (and is hereby irrevocably authorized by
Lenders to) execute a release of such Borrower from its obligations as a
Borrower under the Loan Documents, including its obligation to pay the
Obligation, such Guarantor from its Guaranty, and/or the Liens granted to
Administrative Agent for the benefit of Lenders in the Stock of such Foreign
Subsidiary (along with the termination of the related Foreign Stock Pledge)
substantially in the forms of EXHIBITS G-1, G-2, and/or G-3, as applicable;
provided that nothing herein shall permit Administrative Agent to release ACS as
a Borrower without the consent of all Lenders; and provided further that
Administrative Agent shall not be required to execute any such document other
than such a release of such Borrowers, Liens, and Guaranties in substantially
the forms attached hereto as EXHIBITS G-1, G-2, and/or G-3, as applicable.

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

SECTION 7 CONDITIONS PRECEDENT.

         7.1 CONDITIONS PRECEDENT TO CLOSING. This Agreement shall not become
effective, and Lenders shall not be obligated to make their initial extension of
credit, unless Administrative Agent has received all of the agreements,
documents, instruments, and other items described on SCHEDULE 7.1.
Notwithstanding anything to the contrary contained herein, the Agreement shall
be deemed effective upon the making of the initial extension of credit
hereunder.

         7.2 CONDITIONS PRECEDENT TO EACH BORROWING. Lenders will not be
obligated to fund (as opposed to continue or convert) any Borrowing, and no LC
Issuer will be obligated to issue any LC, as the case may be, unless on the date
of such Borrowing or issuance (and after giving effect thereto), as the case may
be: (a) Administrative Agent (and LC Issuer, if applicable) shall have timely
received therefor a Borrowing Notice or a LC Request (together with the
applicable LC Agreement), as the case may be; (b) Administrative Agent and the
applicable LC Issuer shall have received, as applicable, the LC fees provided
for in SECTION 5.5 hereof; (c) all of the representations and warranties of any
Company set forth in the Loan Documents are true and correct in all material
respects (except to the extent that (i) the representations and warranties speak
to a specific date or (ii) the facts on which such representations and
warranties are based have been changed by transactions expressly contemplated or
permitted by the Loan Documents); (d) no Default or Potential Default shall have
occurred and be continuing; and (e) the funding of such Borrowings and issuance
of such LC, as the case may be, is permitted by Law. Each Borrowing Notice and
LC Request delivered to Administrative Agent (or LC Issuers, as applicable)
shall constitute the representation and warranty by Borrowers to Administrative
Agent (or LC Issuers, as applicable) that, as of the Borrowing Date or the date
of issuance of the requested LC, as the case may be, the statements above are
true and correct in all respects. Each condition precedent in this Agreement is
material to the transactions contemplated in this Agreement, and time is of the
essence in respect of each thereof. Subject to the prior written approval of
Required Lenders (or as otherwise set forth in SECTIONS 2.2(c) or 2.3(b)),
Lenders may fund any Borrowing, and LC Issuers may issue any LC, without all
conditions being satisfied, but, to the extent permitted by Law, the same shall
not be deemed to be a waiver of the requirement that each such condition
precedent be satisfied as a prerequisite for any subsequent funding or issuance,
unless Required Lenders specifically waive each such item in writing.

         7.3 CONDITIONS PRECEDENT TO ADDITIONAL BORROWERS, GUARANTORS, OR
FOREIGN STOCK PLEDGES. No Person shall become a Borrower or Guarantor, and no
Pledgor shall deliver a Foreign Stock Pledge until such Person shall have
satisfied the conditions and delivered, or caused to be delivered, to
Administrative Agent, all documents and certificates set forth on SCHEDULE 7.3.
All documentation



                                       36                  ACS CREDIT AGREEMENT
<PAGE>

delivered and satisfaction of conditions pursuant to the requirements of SECTION
7.3 must be reasonably satisfactory to Administrative Agent; provided, however
that upon the delivery to Administrative Agent of all documents and certificates
set forth on SCHEDULE 7.3 with respect to each such Person, the Borrowers shall
be deemed to have complied with SECTION 6.2; and provided further that Borrowers
agree to promptly address any reasonable requests made by Administrative Agent
or Required Lenders concerning any such documents and certificates.

SECTION 8 REPRESENTATIONS AND WARRANTIES. Each Company represents and warrants
to Administrative Agent and Lenders as follows:

         8.1 PURPOSE OF CREDIT FACILITY. Borrowers will use (or will advance
such proceeds to their Subsidiaries to so use) all proceeds of Borrowings for
one or more of the following: (a) to repay the Debt existing under the Existing
Credit Agreements and pay the related costs and expenses; (b) to finance
Acquisitions; (c) for working capital of the Companies; and (d) for general
corporate purposes; provided that, on the Closing Date the proceeds of
Borrowings will not be used to back-stop commercial paper. No Company is engaged
principally, or as one of its important activities, in the business of extending
credit for the purpose of purchasing or carrying any "margin stock" within the
meaning of Regulation U. No part of the proceeds of any Borrowing will be used,
directly or indirectly, for a purpose which violates any Law, including, without
limitation, the provisions of Regulation T, U, or X (as enacted by the Board of
Governors of the Federal Reserve System, as amended).

         8.2 EXISTENCE, GOOD STANDING, AUTHORITY, AND AUTHORIZATIONS. Each
Company is duly organized, validly existing, and in good standing under the Laws
of its jurisdiction of organization. Except where not a Material Adverse Event,
each Company is duly qualified to transact business and is in good standing in
each jurisdiction where the nature and extent of its business and properties
require the same. Except where not a Material Adverse Event, each Company
possesses all the Authorizations necessary or required in the conduct of its
respective business(es), and the same are valid, binding, enforceable, and
subsisting without any defaults thereunder or enforceable adverse limitations
thereon and are not subject to any proceedings or claims opposing the issuance,
development, or use thereof or contesting the validity thereof. No Authorization
which has not been obtained is required by reason of or in connection with the
execution and performance of the Loan Documents by the Loan Parties.

         8.3 SUBSIDIARIES; CAPITAL STOCK. All of the outstanding shares of Stock
of each Company are duly authorized, validly issued, fully paid, and
nonassessable and are owned free and clear of any Liens, restrictions, claims,
or Rights of another Person, other than Permitted Liens, and none of such shares
owned by any Company which is subject to a Foreign Stock Pledge is subject to
any restriction on transfer thereof except for restrictions imposed by
applicable securities Laws and general corporate Laws.

         8.4 AUTHORIZATION AND CONTRAVENTION. The execution and delivery by each
Loan Party of each Loan Document to which it is a party and the performance by
such Loan Party of its obligations thereunder (a) are within the organizational
power of such Loan Party; (b) will have been duly authorized by all necessary
organizational action on the part of such Loan Party when such Loan Document is
executed and delivered, (c) require no action by or in respect of, or filing
with, any Governmental Authority, which action or filing has not been taken or
made on or prior to the Closing Date (or if later, the date of execution and
delivery of such Loan Document), (d) will not violate any provision of the
Constituent Documents of such Loan Party, (e) except where not a Material
Adverse Event, will not violate any provision of Law applicable to it, (f)
except where not a Material Adverse Event, will not violate any Material
Agreements to which it is a party, and (g) will not result in the creation or
imposition of any Lien on any asset of any Loan Party, other than Permitted
Liens.

         8.5 BINDING EFFECT. Upon execution and delivery by all parties thereto,
each Loan Document will constitute a legal, valid, and binding obligation of
each Loan Party party thereto,



                                       37                  ACS CREDIT AGREEMENT
<PAGE>

enforceable against each such Loan Party in accordance with its terms, except as
enforceability may be limited by applicable Debtor Relief Laws and general
principles of equity.

         8.6 FINANCIAL STATEMENTS. The Current Financials were prepared in
accordance with GAAP and present fairly, in all material respects, the
consolidated financial condition, results of operations, and cash flows of the
Companies as of, and for the portion of the fiscal year ending on, the date or
dates thereof (subject only to normal year-end audit adjustments for interim
statements). There were no material liabilities, direct or indirect, fixed or
contingent, of the Companies as of the date or dates of the Current Financials
which are required under GAAP to be reflected therein or in the notes thereto,
and are not so reflected. Except for transactions directly related to,
specifically contemplated by, or expressly permitted by, the Loan Documents, and
except where not a Material Adverse Event, (a) there have been no changes in the
consolidated financial condition of the Companies from that shown in the Current
Financials after the date of such Current Financials, and (b) no Company has
incurred any liability (including, without limitation, any liability under any
Environmental Law), direct or indirect, fixed or contingent, after such date.

         8.7 LITIGATION, CLAIMS, INVESTIGATIONS. Except as disclosed on SCHEDULE
8.7 and where not a Material Adverse Event, no Company is subject to, or aware
of the threat of, any Litigation which is reasonably likely to be determined
adversely to any Company. Except where not a Material Adverse Event, there are
no formal complaints, suits, claims, investigations, or proceedings initiated at
or by any Governmental Authority pending or (to the knowledge of ACS) threatened
by or against any Company, nor any judgments, decrees, or orders of any
Governmental Authority outstanding against any Loan Party or any Subsidiary
thereof.

         8.8 TAXES. All Tax returns of each Company required to be filed have
been filed (or extensions have been granted) prior to delinquency, except for
any such returns for which the failure to so file is not a Material Adverse
Event, and all Taxes imposed upon each Company which are due and payable have
been paid prior to delinquency, other than Taxes for which the criteria for
Permitted Liens (as specified in SECTION 9.13(b)(VI)) have been satisfied or for
which nonpayment thereof is not a Material Adverse Event.

         8.9 ENVIRONMENTAL MATTERS. No Company (a) knows of any environmental
condition or circumstance, such as the presence or Release of any Hazardous
Substance, on any property presently or previously owned by any Company that is
a Material Adverse Event, (b) knows of any violation by any Company of any
Environmental Law, except for such violations that are not a Material Adverse
Event, or (c) knows that any Company is under any obligation to remedy any
violation of any Environmental Law, except for such obligations that are not a
Material Adverse Event; provided, however, that except where not a Material
Adverse Event, each Company (x) to the best of its knowledge, has in full force
and effect all Environmental Permits, licenses, and approvals required to
conduct its operations and is operating in substantial compliance thereunder,
and (y) has taken prudent steps to determine that its properties and operations
are not in violation of any Environmental Law.

         8.10 EMPLOYEE BENEFIT PLANS. (a) No Employee Plan has incurred an
"accumulated funding deficiency" (as defined in Section 302 of ERISA and Section
412 of the Code) which is a Material Adverse Event, (b) no Company or ERISA
Affiliate thereof has incurred liability to the PBGC or with respect to an
Employee Plan, which liability is currently due and remains unpaid under Title
IV of ERISA and which is a Material Adverse Event, (c) each Employee Plan
subject to ERISA and the Code complies in all respects, both in form and
operation, with ERISA and the Code, except for such non-compliance that is not a
Material Adverse Event, (d) no ERISA Event has occurred or is reasonably
expected to occur with respect to any Employee Plan or Multiemployer Plan which
is a Material Adverse Event, (e) the present value of all accrued benefits under
each Employee Plan (based on actuarial assumptions used for funding purposes in
the most recent actuarial valuation prepared by the Employee Plan's actuary with


                                       38                  ACS CREDIT AGREEMENT
<PAGE>

respect to such Employee Plan) did not, as of the last annual actuarial
valuation date for such Employee Plan, exceed the then-current value of the
assets of such Employee Plan except for such an excess that is not a Material
Adverse Event, and (f) the present value of accrued benefits under each Employee
Plan (based on PBGC actuarial assumptions used for plan termination), does not
exceed the value of the assets of such Employee Plan by more than $25,000,000.

         8.11 PROPERTIES; LIENS. Except where not a Material Adverse Event, each
Company has good and marketable title to all its property reflected on the
Current Financials, except as otherwise permitted by the Loan Documents. Except
for Permitted Liens, there is no Lien on any property of any Company.

         8.12 GOVERNMENT REGULATIONS. No Company is subject to regulation under
the Investment Company Act of 1940, as amended, the Public Utility Holding
Company Act of 1935, as amended, or any other Law (other than Regulations T, U,
and X of the Board of Governors of the Federal Reserve System) which regulates
the incurrence of Debt.

         8.13 INTELLECTUAL PROPERTY. Except where not a Material Adverse Event,
each Company owns or has sufficient and legally enforceable Rights to use all
material licenses, patents, patent applications, copyrights, service marks,
trademarks, trademark applications, and trade names necessary to continue to
conduct its businesses as heretofore conducted by it, now conducted by it, and
now proposed to be conducted by it. Each Company is conducting its business
without infringement or claim of infringement of any license, patent, copyright,
service mark, trademark, trade name, trade secret, or other intellectual
property right of others, other than any such infringements or claims which, if
successfully asserted against or determined adversely to any Company, is not a
Material Adverse Event. No infringement or claim of infringement by others of
any material license, patent, copyright, service mark, trademark, trade name,
trade secret, or other intellectual property of any Company exists, except where
such Company is actively prosecuting to cease such infringement or such
infringement (if it continued unabated) is not a Material Adverse Event.

         8.14 COMPLIANCE WITH LAWS. No Company is in violation of any Laws
(including, without limitation, Environmental Laws) other than such violations
which are not a Material Adverse Event. No Company has received notice alleging
any noncompliance with any Laws, except for such noncompliance which no longer
exists, or which is not a Material Adverse Event.

         8.15 REGULATION U. "Margin Stock" (as defined in Regulation U)
constitutes less than 25% of those assets of the Companies, which are subject to
any limitation on sale, pledge, or other restrictions hereunder.

         8.16 FULL DISCLOSURE. No representation or warranty of any Loan Party
contained in this Agreement (including any Schedule furnished in connection
herewith) contains any untrue statement of a material fact. No other document,
certificate, or written statement furnished to Administrative Agent or any
Lender by or on behalf of any Loan Party for use in connection with the
transactions contemplated in this Agreement, taken as a whole with other
documents, certificates, or written statements furnished contemporaneously
therewith, contains any untrue statement of fact or omits to state a material
fact (known to such Loan Party in the case of any documents not furnished by it)
necessary in order to make the statements contained therein not misleading in
light of the circumstances under which the same were made.

         8.17 NO DEFAULT. No Default or Potential Default exists or will arise
as a result of the execution of the Loan Documents or of any Borrowing
hereunder.

         8.18 CONTINGENT "EARN-OUT" PAYMENTS. SCHEDULE 8.18 (as supplemented and
modified in writing from time to time to reflect any changes to such Schedule as
a result of transactions permitted by


                                       39                  ACS CREDIT AGREEMENT
<PAGE>

the Loan Documents) describes all material contractual agreements entered into
by any Company to make contingent ("earn-out") payments based on the financial
performance of any Company or its Subsidiaries. For purposes of this SECTION
8.18, such transactions are "material" if they require any Company to pay over
the course of such transactions, more than $25,000,000 with respect to any
individual transaction.

SECTION 9 COVENANTS. Each Loan Party covenants and agrees (and agrees to cause
its Subsidiaries and, with respect to SECTION 9.10, its ERISA Affiliates) to
perform, observe, and comply with each of the following covenants applicable to
such Person, from the Closing Date and so long thereafter as Lenders are
committed to fund Borrowings and any LC Issuer is committed to issue LCs under
this Agreement and thereafter until the payment in full of the Principal Debt

         9.4 INSPECTIONS. Upon reasonable notice, the Companies shall allow
Administrative Agent or any Lender (or their respective Representatives) to
inspect any of their properties, to review reports, files, and other records and
to make and take away copies thereof, to conduct tests or investigations, and to

creditors, directors, officers, employees, other representatives, and
independent accountants of the Companies, from time to time, during reasonable
business hours.

         9.5 TAXES. Except where not a Material Adverse Event, each Company

against which reserves or other provision required by GAAP has been made).
Notwithstanding anything to the contrary contained in this Agreement or any
other agreement or instrument executed in connection with the payment of any of
the Obligation, the amount of the Obligation for which any Borrower (other than
ACS) is liable shall be limited to an aggregate amount equal to the largest
amount that would not render such Borrower's obligations hereunder subject to

<PAGE>

failure to so maintain its existence, good standing, or authority to transact
business is a Material Adverse Event; (b) maintain all licenses, permits, and
franchises necessary for its business where the failure to so maintain is a
Material Adverse Event; and (c) keep all of its assets which are useful in and
necessary to its business in good working order and condition (ordinary wear and
tear excepted) and make all necessary repairs thereto and replacements thereof
except where the failure to so maintain is a Material Adverse Event.

         9.8 INSURANCE. The Companies shall, at their cost and expense, maintain
with financially sound, responsible, and reputable insurance companies or
associations insurance covering its properties and business against such risks,
in such amounts, and with no greater risk retention as are customarily
maintained, insured, or retained by companies of established repute engaged in
the same or similar business as such Company. Upon the request of Administrative
Agent, ACS will furnish to Lenders information presented in reasonable detail as

insolvency, bankruptcy, or lack of corporate or partnership power of any other
obligor at any time liable for any of the Obligation, whether now existing or
occurring in the future; (c) the unenforceability of any of the Obligation
against any other obligor or any security securing same because it exceeds the
amount permitted by Law, the act of creating it is ultra vires, the officers
creating it exceeded their authority or violated their fiduciary duties in
connection with it, or otherwise; or (d) any payment of the Obligation to
Administrative Agent or any Lender is held to constitute a preference under any
Debtor Relief Law or for any other reason Administrative Agent or any Lender is
required to refund that payment or make payment to someone else (and in each
such instance each Guaranty will be reinstated in an amount equal to that
payment).

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

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

         11.5 NOT IN CONTROL. Nothing in any Loan Document shall, or shall be
deemed to (a) give any Agent or any Lender the Right to exercise control over
the assets (including real property), affairs, or management of any Company, (b)
preclude or interfere with compliance by any Company with any Law, or (c)
require any act or omission by any Company that may be harmful to Persons or
property. The Agents and the Lenders have no fiduciary relationship with or
fiduciary duty to any Company arising out of or in connection with the Loan
Documents, and the relationship between the Agents and the Lenders, on the one
hand, and Companies, on the other hand, in connection with the Loan Documents is
solely that of debtor and creditor. The power of the Agents and Lenders under
the Loan Documents is limited to the Rights provided in the Loan Documents,
which Rights exist solely to assure payment and performance of the Obligation
and may be exercised in a manner calculated by the Agents and Lenders in their
respective good faith business judgment.

         11.6 COURSE OF DEALING. The acceptance by Administrative Agent or
Lenders at any time and from time to time of partial payment on the Obligation
shall not be deemed to be a waiver of any Default then existing. No waiver by
Administrative Agent, Required Lenders, or Lenders of any Default shall be


                                       48                  ACS CREDIT AGREEMENT
<PAGE>

deemed to be a waiver of any other then-existing or subsequent Default. No delay
or omission by Administrative Agent, Required Lenders, or Lenders in exercising
any Right under the Loan Documents shall impair such Right or be construed as a
waiver thereof or any acquiescence therein, nor shall any single or partial
exercise of any such Right preclude other or further exercise thereof, or the
exercise of any other Right under the Loan Documents or otherwise.

         11.7 CUMULATIVE RIGHTS. All Rights available to Administrative Agent
and Lenders under the Loan Documents are cumulative of and in addition to all
other Rights granted to Administrative Agent and Lenders at Law or in equity,
whether or not the Obligation is due and payable and whether or not
Administrative Agent or Lenders have instituted any suit for collection,
foreclosure, or other action in connection with the Loan Documents.

         11.8 APPLICATION OF PROCEEDS. Any and all proceeds ever received by
Administrative Agent or Lenders from the exercise of any Rights pertaining to
the Obligation shall be applied to the Obligation in the order and manner set
forth in SECTION 3.12.

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

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

         11.11 INDEMNIFICATION. EACH BORROWER AND EACH OTHER LOAN PARTY (BY
EXECUTION OF SUPPLEMENTAL AGREEMENTS TO THE LOAN DOCUMENTS, A GUARANTY, OR
COLLATERAL DOCUMENTS) AGREES, JOINTLY AND SEVERALLY, TO INDEMNIFY AND HOLD
HARMLESS EACH AGENT, ARRANGER, LC ISSUER, AND EACH LENDER AND EACH OF THEIR
RESPECTIVE AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES,
AGENTS, ATTORNEYS, AND ADVISORS (EACH, AN "INDEMNIFIED PARTY") FROM AND AGAINST
ANY AND ALL CLAIMS, DAMAGES, LOSSES, LIABILITIES (INCLUDING, WITHOUT LIMITATION,
ANY ENVIRONMENTAL 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 BORROWINGS (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 11.11
APPLIES, SUCH INDEMNITY SHALL BE EFFECTIVE WHETHER OR NOT SUCH INVESTIGATION,
LITIGATION OR PROCEEDING IS BROUGHT BY ANY BORROWER, ITS DIRECTORS,
SHAREHOLDERS, OR CREDITORS, OR AN INDEMNIFIED PARTY OR ANY OTHER PERSON OR ANY
INDEMNIFIED PARTY IS OTHERWISE A PARTY THERETO AND WHETHER OR NOT THE
TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED. EACH BORROWER AND EACH OTHER
LOAN PARTY (BY EXECUTION OF SUPPLEMENTAL AGREEMENTS TO THE LOAN DOCUMENTS, A
GUARANTY, OR COLLATERAL DOCUMENTS) AGREES NOT TO ASSERT ANY CLAIM AGAINST ANY
INDEMNIFIED PARTY ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT,
CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR OTHERWISE RELATING TO THE
LOAN DOCUMENTS, ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR THE ACTUAL OR
PROPOSED USE OF THE PROCEEDS OF THE BORROWINGS. WITHOUT PREJUDICE TO THE
SURVIVAL OF ANY OTHER AGREEMENT OF THE COMPANIES HEREUNDER, THE AGREEMENTS AND
OBLIGATIONS OF THE LOAN PARTIES CONTAINED IN THIS SECTION 11.11 SHALL SURVIVE
THE PAYMENT IN FULL OF THE BORROWINGS AND ALL OTHER AMOUNTS PAYABLE UNDER THE
LOAN DOCUMENTS AND THE TERMINATION OF THE REVOLVER COMMITMENT.

SECTION 12 AGREEMENT AMONG LENDERS.

         12.1 ADMINISTRATIVE AGENT; LC ISSUERS.

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

                  (b) Actions of LC Issuers. Each LC Issuer shall act on behalf
         of the Lenders with respect to any LC issued by it and the documents
         associated therewith, and the LC Issuer shall have all of the benefits
         and immunities (i) provided to the Administrative Agent in this SECTION
         12 with respect to any acts taken or omissions suffered by such LC
         Issuer in connection with LCs


                                       50                  ACS CREDIT AGREEMENT
<PAGE>

         issued by it or proposed to be issued by it and the LC Agreements
         pertaining to such LCs as fully as if the term "Administrative Agent"
         as used in this SECTION 12 included the LC Issuer with respect to such
         acts or omissions, and (ii) as additionally provided herein with
         respect to the LC Issuer.

                  (c) Resignation of Administrative Agent. Successor
         Administrative Agents. Administrative Agent may resign at any time as
         Administrative Agent under the Loan Documents by giving written notice
         thereof to Lenders and may be removed as Administrative Agent under the
         Loan Documents at any time with cause by Required Lenders; provided
         that any such resignation by Wells Fargo shall also constitute its
         resignation as the Swing Line Lender and a LC Issuer. Should the
         initial or any successor Administrative Agent ever cease to be a party
         hereto or should the initial or any successor Administrative Agent ever
         resign or be removed as Administrative Agent, then Required Lenders
         shall elect the successor Administrative Agent from among the Lenders
         (other than the resigning Administrative Agent), with the consent of
         ACS (not unreasonably withheld), provided no Default or Potential
         Default has occurred and is continuing. If no successor Administrative
         Agent shall have been so appointed by Required Lenders and consented to
         by ACS as provided hereinabove, within 30 days after the retiring
         Administrative Agent's giving of notice of resignation or Required
         Lenders' removal of the retiring Administrative Agent, then the
         retiring Administrative Agent may, on behalf of Lenders, with the
         consent of ACS (not unreasonably withheld), provided no Default or
         Potential Default has occurred and is continuing, appoint a successor
         Administrative Agent, which shall be a commercial bank having a
         combined capital and surplus of at least $1,000,000,000. Upon the
         acceptance of any appointment as Administrative Agent under the Loan
         Documents by a successor Administrative Agent, such successor
         Administrative Agent shall thereupon succeed to and become vested with
         all the Rights of the retiring Administrative Agent and Swing Line
         Lender, and the respective terms "Administrative Agent" and "Swing Line
         Lender" shall mean such successor administrative agent and swing line
         lender, and the retiring Administrative Agent and Swing Line Lender
         shall be discharged from its duties and obligations of Administrative
         Agent under the Loan Documents, and each Lender shall execute such
         documents as any Lender may reasonably request to reflect such change
         in and under the Loan Documents. After any retiring Administrative
         Agent's resignation or removal as Administrative Agent under the Loan
         Documents, the provisions of this SECTION 12 shall inure to its benefit
         as to any actions taken or omitted to be taken by it while it was
         Administrative Agent under the Loan Documents.

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

                  (e) Other Activities of Administrative Agent. Administrative
         Agent and its Affiliates may now or hereafter be engaged in one or more
         loan, letter of credit, leasing, or other financing transactions with
         any Company, act as trustee or depositary for any Company, or otherwise
         be engaged in other transactions with any Company (collectively, the
         "OTHER ACTIVITIES") not the subject of the Loan Documents. Without
         limiting the Rights of Lenders specifically set forth in the Loan
         Documents, Administrative Agent and its Affiliates shall not be


                                       51                  ACS CREDIT AGREEMENT
<PAGE>

         responsible to account to Lenders for such other activities, and no
         Lender shall have any interest in any other activities, any present or
         future guaranties by or for the account of any Company which are not
         contemplated or included in the Loan Documents, any present or future
         offset exercised by Administrative Agent and its Affiliates in respect
         of such other activities, any present or future property taken as
         security for any such other activities, or any property now or
         hereafter in the possession or control of Administrative Agent or its
         Affiliates which may be or become security for the obligations of Loan
         Parties 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 such other
         activities; provided that, if any payments in respect of such
         guaranties or such property or the proceeds thereof shall be applied to
         reduction of the Obligation arising under the Loan Documents, then each
         Lender shall be entitled to share in such application on a Pro Rata
         basis.

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

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

         12.4 DELEGATION OF DUTIES; RELIANCE. Administrative Agent may perform
any of its duties or exercise any of its Rights under the Loan Documents by or
through its Representatives. Administrative Agent and its Representatives shall
(a) be entitled to rely upon (and shall be protected in relying upon) any
writing, resolution, notice, consent, certificate, affidavit, letter, cablegram,
telecopy, telegram, telex or teletype message, statement, order, or other
documents or conversation believed by it or them to be genuine and correct and
to have been signed or made by the proper Person and, with respect to legal
matters, upon opinions of counsel selected by Administrative Agent, (b) be
entitled to deem and treat each Lender as the owner and holder of the Obligation
owed to such Lender for all purposes until, subject to SECTION 13.12, written
notice of the assignment or transfer thereof shall have been given to and
received by Administrative Agent (and any request, authorization, consent, or
approval of any Lender shall be conclusive and binding on each subsequent
holder, assignee, or transferee of the Obligation owed to such Lender or portion
thereof until such notice is given and received), (c) not be deemed to have
notice of the occurrence of a Default or Potential Default unless a responsible
officer of Administrative Agent, who handles matters associated with the Loan
Documents and transactions thereunder, has received written notice from a Lender
or Borrowers and stating that such notice is a "Notice of Default," and (d) be
entitled to consult with legal counsel (including counsel for any Company),
independent accountants, and other experts selected by Administrative Agent and
shall not be liable for any action taken or omitted to be taken in good faith by
it in accordance with the advice of such counsel, accountants or experts.

         12.5 LIMITATION OF LIABILITY.

                  (a) General. None of the Agents or any of their respective
         Representatives shall be liable for any action taken or omitted to be
         taken by it or them under the Loan Documents in good faith and
         reasonably believed by it or them to be within the discretion or power
         conferred upon it


                                       52                  ACS CREDIT AGREEMENT
<PAGE>

         or them by the Loan Documents or be responsible for the consequences of
         any error of judgment, except for fraud, gross negligence, or willful
         misconduct; and none of the Agents or any of their respective
         Representatives has a fiduciary relationship with any Lender by virtue
         of the Loan Documents (provided that, nothing herein shall negate the
         obligation of Administrative Agent to account for funds received by it
         for the account of any Lender).

                  (b) Non-Discretionary Actions; Indemnification. Unless
         indemnified to its satisfaction against loss, cost, liability, and
         expense, neither Administrative Agent nor any other Agent shall be
         compelled to do any act under the Loan 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
         Administrative Agent requests instructions from Lenders or Required
         Lenders, as the case may be, with respect to any act or action
         (including, but not limited to, any failure to act) in connection with
         any Loan Document, Administrative Agent shall be entitled (but shall
         not be required) to refrain (without incurring any liability to any
         Person by so refraining) from such act or action unless and until it
         has received such instructions. Except where action of Required Lenders
         or all Lenders is required in the Loan Documents, Administrative Agent
         may act hereunder in its own discretion without requesting
         instructions. In no event, however, shall Administrative Agent or any
         of its respective Representatives be required to take any action which
         it or they determine could incur for it or them criminal or onerous
         civil liability. Without limiting the generality of the foregoing, no
         Lender shall have any right of action against Administrative Agent as a
         result of Administrative Agent's acting or refraining from acting
         hereunder in accordance with the instructions of Required Lenders (or
         all Lenders if required in the Loan Documents).

                  (c) Independent Credit Decision. Neither Administrative Agent
         nor any other Agent or LC Issuer shall be responsible in any manner to
         any Lender or any Participant for, and each Lender represents and
         warrants that it has not relied upon Administrative Agent, any other
         Agent, or any LC Issuer in respect of, (i) the creditworthiness of any
         Loan Party and the risks involved to such Lender, (ii) the
         effectiveness, enforceability, genuineness, validity, or the due
         execution of any Loan Document, (iii) any representation, warranty,
         document, certificate, report, or statement made therein or furnished
         thereunder or in connection therewith, (iv) the existence, priority, or
         perfection of any Lien hereafter granted or purported to be granted
         under any Loan Document, or (v) observation of or compliance with any
         of the terms, covenants, or conditions of any Loan Document on the part
         of any Loan Party. Each Lender agrees to indemnify Administrative Agent
         and each LC Issuer and their respective Representatives and hold them
         harmless from and against (but limited to such Lender's Pro Rata Part
         of) any and all liabilities, obligations, losses, damages, penalties,
         actions, judgments, suits, costs, reasonable expenses, and reasonable
         disbursements of any kind or nature whatsoever which may be imposed on,
         asserted against, or incurred by them in any way relating to or arising
         out of the Loan Documents or any action taken or omitted by them under
         the Loan Documents (INCLUDING ANY OF THE FOREGOING ARISING FROM THE
         NEGLIGENCE OF ADMINISTRATIVE AGENT, ANY LC ISSUER, OR THEIR
         REPRESENTATIVES), to the extent Administrative Agent, LC Issuer, and
         their respective Representatives are not reimbursed for such amounts by
         any Loan Party (provided that, Administrative Agent, any LC Issuer, and
         their respective Representatives shall not have the right to be
         indemnified hereunder for its or their own fraud, gross negligence, or
         willful misconduct).

         12.6 DEFAULT; COLLATERAL.

                  (a) Upon the occurrence and continuance of a Default, Lenders
         agree to promptly confer in order that Required Lenders or Lenders, as
         the case may be, may agree upon a course of action for the enforcement
         of the Rights of Lenders; and Administrative Agent shall be entitled to
         refrain from taking any action (without incurring any liability to any
         Person for so refraining)


                                       53                  ACS CREDIT AGREEMENT
<PAGE>

         unless and until Administrative Agent shall have received instructions
         from Required Lenders. All Rights of action under the Loan Documents
         and all Rights to the Collateral, if any, hereunder may be enforced by
         Administrative Agent and any suit or proceeding instituted by
         Administrative Agent in furtherance of such enforcement shall be
         brought in its name as Administrative Agent without the necessity of
         joining as plaintiffs or defendants any other Lender, and the recovery
         of any judgment shall be for the benefit of Lenders subject to the
         expenses of Administrative Agent. In actions with respect to any
         property of the Loan Parties, Administrative Agent is acting for the
         ratable benefit of each Lender. Any and all agreements to subordinate
         (whether made heretofore or hereafter) other indebtedness or
         obligations of the Loan Parties to the Obligation shall be construed as
         being for the ratable benefit of each Lender.

                  (b) In case of the pendency of any receivership, insolvency,
         liquidation, bankruptcy, reorganization, arrangement, adjustment,
         composition, or other judicial proceeding relative to any Loan Party,
         Administrative Agent (irrespective of whether any Principal Debt or LC
         Exposure shall then be due and payable as herein expressed or by
         declaration or otherwise and irrespective of whether the Administrative
         Agent shall have made any demand on any Borrower) shall be entitled and
         empowered, by intervention in such proceeding or otherwise

                           (i) to file and prove a claim for the whole amount of
                  the principal and interest owing and unpaid in respect of the
                  Principal Debt and interest due thereon, LC Exposure, and all
                  other Obligation that is owing and unpaid and to file such
                  other documents as may be necessary or advisable in order to
                  have the claims of the Lenders and Administrative Agent
                  (including any claim for the reasonable compensation,
                  expenses, disbursements, and advances of the Lenders and
                  Administrative Agent and their respective agents and counsel
                  and all other amounts due the Lenders and the Administrative
                  Agent under SECTIONS 5 and 11.10) allowed in such judicial
                  proceeding; and

                           (ii) to collect and receive any monies or other
                  property payable or deliverable on any such claims and to
                  distribute the same;

         and any custodian, receiver, assignee, trustee, liquidator,
         sequestrator, or other similar official in any such judicial proceeding
         is hereby authorized by each Lender to make such payments to
         Administrative Agent and, in the event that Administrative Agent shall
         consent to the making of such payments directly to the Lenders, to pay
         to Administrative Agent any amount due for the reasonable compensation,
         expenses, disbursements, and advances of Administrative Agent and its
         agents and counsel, and any other amounts due the Administrative Agent
         under SECTIONS 5 and 11.10.

         Nothing contained herein shall be deemed to authorize Administrative
         Agent to authorize or consent to or accept or adopt on behalf of any
         Lender any plan of reorganization, arrangement, adjustment, or
         composition affecting the Obligation or the Rights of any Lender or to
         authorize Administrative Agent to vote in respect of the claim of any
         Lender in any such proceeding.

                  (c) Each Lender authorizes and directs Administrative Agent to
         enter into the Foreign Stock Pledges for the benefit of the Lenders.
         Except to the extent unanimity is required hereunder, each Lender
         agrees that any action taken by the Required Lenders in accordance with
         the provisions of the Loan Documents, and the exercise by the Required
         Lenders of the powers set forth herein or therein, together with such
         other powers as are reasonably incidental thereto, shall be authorized
         and binding upon all of the Lenders.

<PAGE>


                  (d) Administrative Agent is hereby authorized on behalf of all
         of the Lenders, without the necessity of any notice to or further
         consent from any Lender, from time to time to take any action with
         respect to any Collateral or Foreign Stock Pledges which may be
         necessary to perfect and maintain perfected the Liens upon the
         Collateral granted pursuant to the Foreign Stock Pledges.

                  (e) Administrative Agent shall have no obligation whatsoever
         to any Lender or to any other Person to assure that the Collateral
         exists or is owned by any Loan Party or is cared for, protected, or
         insured or has been encumbered or that the Liens granted to
         Administrative Agent herein or pursuant hereto have been properly or
         sufficiently or lawfully created, perfected, protected, or enforced, or
         are entitled to any particular priority, or to exercise at all or in
         any particular manner or under any duty of care, disclosure, or
         fidelity, or to continue exercising, any of the Rights granted or
         available to Administrative Agent in this SECTION 12.6 or in any
         Foreign Stock Pledge; it being understood and agreed that in respect of
         the Collateral, or any act, omission, or event related thereto,
         Administrative Agent may act in any manner it may deem appropriate, in
         its sole discretion, given Administrative Agent's own interest in the
         Collateral as one of the Lenders and that Administrative Agent shall
         have no duty or liability whatsoever to any Lender, other than to act
         without gross negligence or willful misconduct.

                  (f) Lenders hereby irrevocably authorize Administrative Agent,
         at its option and in its discretion, to release any Lien granted to or
         held by Administrative Agent upon any Collateral: (i) upon termination
         of the Revolver Commitment and payment and satisfaction of the
         Obligation; (ii) upon the sale, transfer, or disposition of Collateral
         which is expressly permitted pursuant to the Loan Documents; (iii) as
         contemplated in SECTION 6.2; or (iv) if approved, authorized, or
         ratified in writing by all necessary Lenders. Upon request by
         Administrative Agent at any time, Lenders will confirm in writing
         Administrative Agent's authority to release particular types or items
         of Collateral pursuant to this SECTION 12.6.

                  (g) In furtherance of the authorizations set forth in this
         SECTION 12.6, each Lender hereby irrevocably appoints Administrative
         Agent its attorney-in-fact, with full power of substitution, for and on
         behalf of and in the name of each such Lender, (i) to enter into
         Foreign Stock Pledges (including, without limitation, any appointments
         of substitute trustees under any Foreign Stock Pledge), (ii) to take
         action with respect to the Collateral and Foreign Stock Pledges to
         perfect, maintain, and preserve Lenders' Liens, and (iii) to execute
         instruments of release or to take other action necessary to release
         Liens upon any Collateral to the extent authorized in PARAGRAPH (f)
         hereof. This power of attorney shall be liberally, not restrictively,
         construed so as to give the greatest latitude to Administrative Agent's
         power, as attorney, relative to the Collateral matters described in
         this SECTION 12.6. The powers and authorities herein conferred on
         Administrative Agent may be exercised by Administrative Agent through
         any Person who, at the time of the execution of a particular
         instrument, is an officer of Administrative Agent. The power of
         attorney conferred by this SECTION 12.6(g) is granted for valuable
         consideration and is coupled with an interest and is irrevocable so
         long as the Obligation, or any part thereof, shall remain unpaid or
         Lenders are obligated to make any Borrowings under the Loan Documents.

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

<PAGE>


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

         12.9 BENEFITS OF AGREEMENT. None of the provisions of this SECTION 12
shall inure to the benefit of any Company or any other Person other than
Lenders; consequently, no Company or any other Person shall be entitled to rely
upon, or to raise as a defense, in any manner whatsoever, the failure of any
Agent or any Lender to comply with such provisions.

         12.10 AGENTS. None of the Lenders identified in this Agreement as a
"Co-Syndication Agent," "Co-Documentation Agent," or "Senior Managing Agent"
shall have any Rights, powers, obligations, liabilities, responsibilities, or
duties under the Loan Documents other than those applicable to all Lenders as
such. Without limiting the foregoing, none of the Lenders so identified as a
"Co-Syndication Agent," "Co-Documentation Agent," or "Senior Managing Agent"
shall have or be deemed to have any fiduciary relationship with any Lender. Any
Lender that is a "Co-Syndication Agent," "Co-Documentation Agent," or "Senior
Managing Agent," may voluntarily relinquish its title by giving written notice
thereof to Administrative Agent and Borrowers. Upon such relinquishments, a
successor "Co-Syndication Agent," "Co-Documentation Agent," or "Senior Managing
Agent" may be appointed upon the mutual agreement of Borrowers and
Administrative Agent.

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

         SECTION 13 MISCELLANEOUS.

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

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

         13.3 COMMUNICATIONS; FACSIMILE COPIES.

                  (a) General. Unless otherwise expressly provided herein, all
         notices and other communications provided for hereunder shall be in
         writing (including by facsimile transmission). All such written notices
         shall be mailed, faxed or delivered to the applicable address,
         facsimile number or (subject to CLAUSE (c) below) electronic mail
         address, and all notices and other communications expressly permitted
         hereunder to be given by telephone shall be made to the applicable
         telephone number, as follows:

                           (i) if to Administrative Agent, to the address,
                  facsimile number, electronic mail address or telephone number
                  specified for Administrative Agent on SCHEDULE 2.1 or to such
                  other address, facsimile number, electronic mail address, or
                  telephone number as shall be designated by such party in a
                  notice to the other parties;


                                       56                  ACS CREDIT AGREEMENT
<PAGE>

                           (ii) if to Borrowers or any other Loan Party, the
                  address set forth by such Person's signature on the signature
                  page of this Agreement or the Guaranty or Foreign Stock Pledge
                  (as applicable) to which such other Loan Party is a party or
                  to such other address, facsimile number, electronic mail
                  address, or telephone number as shall be designated by such
                  party in a notice to Administrative Agent; and

                           (iii) if to any other Lender, to the address,
                  facsimile number, electronic mail address, or telephone number
                  specified in its Administrative Questionnaire or to such other
                  address, facsimile number, electronic mail address or
                  telephone number as shall be designated by such party in a
                  notice to the other parties.

         All such notices and other communications shall be deemed to be given
         or made upon the earlier to occur of (i) actual receipt by the relevant
         party hereto and (ii) (A) if delivered by hand or by courier, when
         signed for by or on behalf of the relevant party hereto; (B) if
         delivered by mail, four Business Days after deposit in the mails,
         postage prepaid; (C) if delivered by facsimile, when sent and receipt
         has been confirmed by telephone; and (D) if delivered by electronic
         mail (which form of delivery is subject to the provisions of CLAUSE (c)
         below), when delivered; provided, however, that notices and other
         communications to Administrative Agent, any LC Issuer, and the Swing
         Line Lender pursuant to SECTION 2 shall not be effective until actually
         received by such Person. In no event shall a voicemail message be
         effective as a notice, communication or confirmation hereunder.

                  (b) Effectiveness of Facsimile Documents and Signatures. Loan
         Documents may be transmitted and/or signed by facsimile. The
         effectiveness of any such documents and signatures shall, subject to
         applicable Law, have the same force and effect as manually-signed
         originals and shall be binding on all Loan Parties, Administrative
         Agent, and the Lenders. Administrative Agent may also require that any
         such documents and signatures be confirmed by a manually-signed
         original thereof; provided, however, that the failure to request or
         deliver the same shall not limit the effectiveness of any facsimile
         document or signature.

                  (c) Limited Use of Electronic Mail. Electronic mail and
         Internet and intranet websites may be used only to distribute routine
         communications, such as financial statements and other information as
         provided in SECTION 9.3, and to distribute Loan Documents for execution
         by the parties thereto, and may not be used for any other purpose.

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

         13.5 SURVIVAL. All covenants, agreements, undertakings,
representations, and warranties made in any of the Loan Documents shall survive
all closings under the Loan Documents and, except as otherwise indicated, shall
not be affected by any investigation made by any party. All rights of, and
provisions relating to, reimbursement and indemnification of Administrative
Agent, any Agent, or any Lender (and any other provision of the Loan Documents
that expressly provides for such survival) shall survive termination of this
Agreement and payment in full of the Obligation.

         13.6 GOVERNING LAW. THE LOAN DOCUMENTS HAVE BEEN ENTERED INTO PURSUANT
TO SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW AND THE SUBSTANTIVE
LAWS OF THE STATE OF NEW YORK (EXCEPT TO THE EXTENT THE LAWS OF ANOTHER
JURISDICTION GOVERN THE CREATION, PERFECTION, VALIDITY, OR ENFORCEMENT OF LIENS
UNDER THE FOREIGN STOCK PLEDGES OR TO THE EXTENT THE LAW OF ANOTHER JURISDICTION
IS EXPRESSLY ELECTED IN A LOAN DOCUMENT), AND THE APPLICABLE FEDERAL LAWS OF THE
UNITED STATES OF AMERICA


                                       57                  ACS CREDIT AGREEMENT
<PAGE>

SHALL GOVERN THE VALIDITY, CONSTRUCTION, ENFORCEMENT AND INTERPRETATION OF THE
LOAN DOCUMENTS WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

         13.7 INVALID PROVISIONS. If any provision in any Loan Document is held
to be illegal, invalid, or unenforceable, such provision shall be fully
severable; the appropriate Loan Document shall be construed and enforced as if
such provision had never comprised a part thereof; and the remaining provisions
thereof shall remain in full force and effect and shall not be affected by such
provision or by its severance therefrom. Administrative Agent, Lenders, and each
Loan Party party to such 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.

         13.8 ENTIRETY. THE RIGHTS AND OBLIGATIONS OF EACH LOAN PARTY, LENDERS,
AND AGENTS SHALL BE DETERMINED SOLELY FROM WRITTEN AGREEMENTS, DOCUMENTS, AND
INSTRUMENTS, AND ANY PRIOR ORAL AGREEMENTS BETWEEN SUCH PARTIES ARE SUPERSEDED
BY AND MERGED INTO SUCH WRITINGS. THIS AGREEMENT (AS AMENDED IN WRITING FROM
TIME TO TIME) AND THE OTHER WRITTEN LOAN DOCUMENTS EXECUTED BY ANY LOAN PARTY,
ANY LENDER, AND/OR ANY AGENT, (TOGETHER WITH ALL COMMITMENT LETTERS AND FEE
LETTERS AS THEY RELATE TO THE PAYMENT OF FEES AFTER THE CLOSING DATE) REPRESENT
THE FINAL AGREEMENT BETWEEN THE LOAN PARTIES, LENDERS, AND AGENTS, AND MAY NOT
BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS BY SUCH PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN SUCH
PARTIES.

         13.9 JURISDICTION; VENUE; SERVICE OF PROCESS; JURY TRIAL. EACH PARTY
HERETO (INCLUDING EACH BORROWER AND EACH OTHER LOAN PARTY BY EXECUTION OF
SUPPLEMENTAL AGREEMENTS TO THE LOAN DOCUMENTS, A GUARANTY, OR A FOREIGN STOCK
PLEDGE), IN EACH CASE FOR ITSELF, ITS SUCCESSORS AND ASSIGNS, HEREBY (A)
IRREVOCABLY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE STATE (PURSUANT TO
SECTION 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW) AND FEDERAL COURTS
LOCATED IN THE BOROUGH OF MANHATTAN IN THE STATE OF NEW YORK, AND AGREES AND
CONSENTS THAT SERVICE OF PROCESS MAY BE MADE UPON IT IN ANY LEGAL PROCEEDING
ARISING OUT OF OR IN CONNECTION WITH THE LOAN DOCUMENTS AND THE OBLIGATION BY
SERVICE OF PROCESS AS PROVIDED BY NEW YORK LAW, (B) IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER
HAVE TO THE LAYING OF VENUE OF ANY LITIGATION ARISING OUT OF OR IN CONNECTION
WITH THE LOAN DOCUMENTS AND THE OBLIGATION BROUGHT IN ANY SUCH COURT, (C)
IRREVOCABLY WAIVES ANY CLAIMS THAT ANY LITIGATION BROUGHT IN ANY SUCH COURT HAS
BEEN BROUGHT IN AN INCONVENIENT FORUM, (D) AGREES TO DESIGNATE AND MAINTAIN AN
AGENT FOR SERVICE OF PROCESS IN NEW YORK IN CONNECTION WITH ANY SUCH LITIGATION
AND TO DELIVER TO ADMINISTRATIVE AGENT EVIDENCE THEREOF, IF REQUESTED; PROVIDED,
HOWEVER, THAT THIS CLAUSE (D) IS LIMITED TO THE LOAN PARTIES, (E) IRREVOCABLY
CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN
ANY SUCH LITIGATION BY THE MAILING OF COPIES THEREOF BY CERTIFIED MAIL, RETURN
RECEIPT REQUESTED, POSTAGE PREPAID, AT ITS ADDRESS SET FORTH HEREIN, (F)
IRREVOCABLY AGREES THAT ANY LEGAL PROCEEDING AGAINST ANY PARTY HERETO ARISING
OUT OF OR IN CONNECTION WITH THE LOAN DOCUMENTS OR THE OBLIGATION MAY BE BROUGHT
IN ONE OF THE AFOREMENTIONED COURTS, AND (G) IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY LAW, ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR
CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY LOAN DOCUMENT OR THE
TRANSACTIONS CONTEMPLATED THEREBY. 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 Loan Parties and each other party to
the Loan Documents acknowledge that this waiver is a material inducement to the
agreement of each party hereto to enter into


                                       58                  ACS CREDIT AGREEMENT
<PAGE>

a business relationship, that each has already relied on this waiver in entering
into the Loan Documents, and each will continue to rely on each of such waivers
in related future dealings. The Loan Parties and each other party to the Loan
Documents warrant and represent that they have reviewed these waivers with their
legal counsel, and that they knowingly and voluntarily agree to each such waiver
following consultation with legal counsel. THE WAIVERS IN THIS SECTION 13.9 ARE
IRREVOCABLE, MEANING THAT THEY MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING,
AND THESE WAIVERS SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, SUPPLEMENTS, AND
REPLACEMENTS TO OR OF THIS OR ANY OTHER LOAN DOCUMENT. In the event of
Litigation, this Agreement may be filed as a written consent to a trial by the
court.

         13.10 AMENDMENTS, CONSENTS, CONFLICTS, AND WAIVERS.

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

                  (b) Any amendment to or consent or waiver under any Loan
         Document which purports to accomplish any of the following must be by
         an instrument in writing executed by Borrowers and executed (or
         approved, as the case may be) by each Lender affected thereby, and, in
         the case of any matter affecting Administrative Agent, by
         Administrative Agent: (i) postpones or delays any date fixed by the
         Loan Documents for any payment or mandatory prepayment of all or any
         part of the Obligation payable to such Lender or Administrative Agent;
         (ii) reduces the interest rate or decreases the amount of any payment
         of principal, interest, fees, or other sums payable to Administrative

         "REQUIRED LENDERS", "PRO RATA", OR "PRO RATA PART"; (iv) changes the
         order of application of any payment or prepayment set forth in SECTIONS

         Administrative Agent; (v) except as otherwise permitted by any Loan

         Commitment; or (vii) changes this CLAUSE (b) or any other matter

         pursuant to SECTION 2.4 or otherwise or to add any new Lender pursuant
         to SECTION 2.4 or otherwise shall be executed by Borrowers and the
         particular existing or new Lender.

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

                  (e) No course of dealing nor any failure or delay by
         Administrative Agent, any Lender, or any of their respective
         Representatives with respect to exercising any Right of Administrative
         Agent or any Lender hereunder shall operate as a waiver thereof. A
         waiver must be in writing and signed by Administrative Agent and
         Required Lenders (or by all Lenders, if


                                       59                  ACS CREDIT AGREEMENT
<PAGE>

         required hereunder) to be effective, and such waiver will be effective
         only in the specific instance and for the specific purpose for which it
         is given.

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

         13.12 SUCCESSORS AND ASSIGNS; ASSIGNMENTS AND PARTICIPATIONS.

                  (a) This Agreement shall be binding upon, and inure to the
         benefit of the parties hereto and their respective successors and
         assigns, except that (i) no Borrower may, directly or indirectly,
         assign or transfer, or attempt to assign or transfer, any of its
         Rights, duties, or obligations under any Loan Documents without the
         express written consent of all Lenders, and (ii) except as permitted
         under this Section, no Lender may transfer, pledge, assign, sell any
         participation in, or otherwise encumber its portion of the Obligation.

                  (b) Each Lender may assign to one or more Eligible Assignees
         all or a portion of its Rights and obligations under the Loan Documents
         (including, without limitation, all or a portion of its Borrowings and
         its Notes -- to the extent any Principal Debt owed to such assigning
         Lender is evidenced by a Note or Notes); provided, however, that:

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

                           (ii) except in the case of an assignment to another
                  Lender or an Affiliate of Lender, or in the case of an
                  assignment of all of a Lender's Rights and obligations under
                  the Loan Documents, any such partial assignment under the
                  Revolver Facility shall not be less than $5,000,000 (unless
                  Administrative Agent and, unless a Default or Potential
                  Default has occurred and is continuing, ACS consents thereto
                  (in their sole discretion) in writing which may be evidenced
                  by their acceptance and execution of the related Assignment
                  and Acceptance Agreement), provided that, no partial
                  assignment (including any assignment among Lenders) may result
                  in any Lender holding less than $5,000,000.

                           (iii) each such assignment by a Lender shall be of a
                  proportionate part of all of the assigning Lender's Rights and
                  obligations under this Agreement and the Notes (to the extent
                  any Principal Debt owed to such assigning Lender is evidenced
                  by a Note or Notes);

                           (iv) the parties to such assignment shall execute and
                  deliver to Administrative Agent for its acceptance an
                  Assignment and Acceptance Agreement in the form of EXHIBIT E
                  hereto ("ASSIGNMENT AND ACCEPTANCE"), together with any Notes
                  (to the extent any Principal Debt owed to such assigning
                  Lender is evidenced by a Note or Notes) subject to such
                  assignment and a processing fee of $3,500 (which fee shall be
                  payable by the parties to such Assignment and Acceptance and
                  is not part of the Obligation), including, without limitation,
                  any assignment between Lenders; and

                           (v) so long as any Lender is an Agent under this
                  Agreement, such Lender (or an Affiliate of such Lender) shall
                  retain an economic interest in the Loan Documents, will not
                  assign all of its Rights, duties, or obligations under the
                  Loan Documents, except to an Affiliate of such Lender, and
                  will not enter into any Assignment and Acceptance that would
                  have the effect of such Lender assigning all of its Rights,
                  duties, or obligations under the Loan Documents to any Person
                  other than an Affiliate of such Lender unless such Agent has
                  relinquished such title in accordance with SECTION 12.1 (with
                  respect to Administrative Agent) or SECTION 12.10 (with
                  respect to the other Agents).

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

                  (c) Administrative Agent shall maintain at its address
         referred to in SECTION 13.3 a copy of each Assignment and Acceptance
         delivered to and accepted by it and a register for the recordation of
         the names and addresses of the Lenders and the Commitment Percentage
         of, Committed Sum of, and Principal Debt owing to, each Lender from
         time to time (the "REGISTER"). The entries in the Register shall be
         conclusive and binding for all purposes, absent manifest error, and
         Borrowers, Administrative Agent, and the Lenders may treat each Person
         whose name is recorded in the Register as a Lender hereunder for all
         purposes of the Loan Documents. The Register shall be available for
         inspection by Borrowers, or any Lender at any reasonable time and from
         time to time upon reasonable prior notice. Upon the consummation of any
         assignment in accordance with this SECTION 13.12, SCHEDULE 2.1 shall
         automatically be deemed amended (to the extent required) by
         Administrative Agent to reflect the name, address, and, where
         appropriate, respective Committed Sum of the assignor and assignee.

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

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


                                       61                  ACS CREDIT AGREEMENT
<PAGE>

         any filing or reporting requirements relating to such participation and
         shall hold Borrowers and Administrative Agent and their respective
         successors, permitted assigns, officers, directors, employees, agents,
         and representatives harmless against the same. Participants shall have
         no Rights under the Loan Documents, other than certain voting Rights as
         provided below. Subject to the following, each Lender shall be entitled
         to obtain (on behalf of its Participants) the benefits of SECTION 4
         with respect to all participations in its part of the Obligation
         outstanding from time to time, so long as Borrowers shall not be
         obligated to pay any amount in excess of the amount that would be due
         to such Lender under SECTION 4 calculated as though no participations
         have been made. No Lender shall sell any participating interest under
         which the Participant shall have any Rights to approve any amendment,
         modification, or waiver of any Loan Document, except to the extent such
         amendment, modification, or waiver extends the due date for payment of
         any amount in respect of principal (other than mandatory prepayments,
         if any), interest, or fees due under the Loan Documents, reduces the
         interest rate or the amount of principal or fees applicable to the
         Obligation (except such reductions as are contemplated by the Loan
         Documents), or releases all or any substantial portion of the
         Guaranties or all or any substantial portion of the Collateral for the
         Obligation under the Loan Documents (except such releases of Guaranties
         or Collateral as are contemplated in SECTION 6.2 or otherwise permitted
         by the Loan Documents); provided that, in those cases where a
         Participant is entitled to the benefits of SECTION 4 or a Lender grants
         Rights to its Participants to approve amendments to or waivers of the
         Loan Documents respecting the matters previously described in this
         sentence, such Lender must include a voting mechanism in the relevant
         participation agreement or agreements, as the case may be, whereby a
         majority of such Lender's portion of the Obligation (whether held by
         such Lender or Participant) shall control the vote for all of such
         Lender's portion of the Obligation. Except in the case of the sale of a
         participating interest to another Lender, the relevant participation
         agreement shall not permit the Participant to transfer, pledge, assign,
         sell participations in, or otherwise encumber its portion of the
         Obligation, unless the consent of the transferring Lender (which
         consent will not be unreasonably withheld) has been obtained.

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

         13.13 DISCHARGE ONLY UPON PAYMENT IN FULL; REINSTATEMENT IN CERTAIN
CIRCUMSTANCES. The obligations of each Loan Party under the Loan Documents shall
remain in full force and effect until termination of the Revolver Commitment,
payment in full of the Principal Debt and of all interest, fees, and other
amounts of the Obligation then due and owing, and expiration of all LCs, except
that SECTIONS 4, 11, and 13, and any other provisions under the Loan Documents
expressly intended to survive by the terms hereof or by the terms of the
applicable Loan Documents, shall survive such termination. Upon the termination
of the Revolver Commitment, payment in full of the Principal Debt and of all
interest, fees, and other amounts of the Obligation then due and owing, and the
expiration of all LCs, all Liens granted by the Loan Parties which secure the
Obligation shall automatically be released and shall terminate without any
further action of any Person, and Administrative Agent shall promptly thereafter
return to ACS all stock certificates and other investment property which
evidences Collateral that it possesses. If at any time any payment of the
principal of or interest on any Note or any other amount payable by Borrowers
under any Loan Document is rescinded or must be otherwise restored or returned
upon the insolvency, bankruptcy, or reorganization of any Borrower or otherwise,
the obligations of each

Loan Party under the Loan Documents with respect to such payment shall be
reinstated as though such payment had been due but not made at such time.

         13.14 CONFIDENTIALITY. Each of Administrative Agent and Lenders agrees
to maintain the confidentiality of the Information (as defined below), except
that Information may be disclosed (a) to its and its Affiliates' directors,
officers, employees, and agents, including accountants, legal counsel, and other
advisors (it being understood that the Persons to whom such disclosure is made
will be informed of the confidential nature of such Information and instructed
to keep such Information confidential); (b) to the extent requested by any
regulatory authority; (c) to the extent required by applicable Laws or
regulations or by any subpoena or similar legal process; (d) to any other party
to this Agreement; (e) in connection with the exercise of any Rights hereunder
or any suit, action, or proceeding relating to this Agreement or the enforcement
of rights hereunder; (f) subject to an agreement containing provisions
substantially the same as those of this Section, to (i) any Eligible Assignee of
or Participant in, or any prospective Eligible Assignee of or Participant in,
any of its Rights or obligations under this Agreement or (ii) any direct or
indirect contractual counterparty or prospective counterparty (or such
contractual counterparty's or prospective counterparty's professional advisor)
to any financial hedge or credit derivative transaction relating to obligations
of the Loan Parties or to any securitization of the Obligation; (g) with the
consent of Borrowers; (h) to the extent such Information (i) becomes publicly
available other than as a result of a breach of this Section or (ii) becomes
available to Administrative Agent or any Lender on a nonconfidential basis from
a source other than any Loan Party. In addition, Administrative Agent and the
Lenders may disclose the existence of this Agreement and information about this
Agreement to market data collectors, similar service providers to the lending
industry, and service providers to Administrative Agent and the Lenders in
connection with the administration and management of this Agreement, the other
Loan Documents, the Commitment, and the Borrowing. For the purposes of this
Section, "INFORMATION" means all information received from any Company relating
to any Company or its business, properties, assets, prospects, financial
condition, or operations, other than any such information that is publicly
available to Administrative Agent or any Lender prior to disclosure by any Loan
Party. Any Person required to maintain the confidentiality of Information as
provided in this Section shall be considered to have complied with its
obligation to do so if such Person has exercised the same degree of care to
maintain the confidentiality of such Information as such Person would accord to
its own confidential information.
