The UK Facility thus encompasses the BG/LC Subfacility and the Overdraft Subfacility. The Lenders under the UK Facility are willing to extend the requested credit on the terms and conditions of this agreement. ACCORDINGLY, for adequate and sufficient consideration, Borrowers, Lenders, and Agents agree as follows: SECTION 1 DEFINITIONS AND TERMS. - --------- --------------------- 1.1 DEFINITIONS. As used in the Loan Documents: ----------- "ADMINISTRATIVE AGENT" means, at any time, NationsBank of Texas, N.A. (or its successor appointed under SECTION 16), acting as administrative, US- collateral, managing, and syndication agent for Lenders under the Loan Documents. Credit Agreement ---------------- "AFFILIATE" of a Person means any other individual or entity who directly or indirectly controls, is controlled by, or is under common control with that Person. For purposes of this definition (a) "control," "controlled by," and "under common control with" mean possession, directly or indirectly, of power to direct or cause the direction of management or policies (whether through ownership of voting securities or other interests, by contract, or otherwise), and (b) the Companies are "Affiliates" of each other. "AGENTS" mean, at any time, Administrative Agent and UK-Collateral Agent. "ALTERNATIVE CURRENCY" means either Pound Sterling or Deutsche Marks (or any other freely convertible currency designated as such by the Administrative Agent). "APPLICABLE MARGIN" means, for any day, the margin of interest over the Base Rate or the Euro Rate, as the case may be, that is applicable when the Base Rate or Euro Rate, as applicable, is determined under this agreement. The Applicable Margin is subject to adjustment (upwards or downwards, as appropriate) based on the ratio of the Companies' Funded Debt to EBITDA as provided in the following table: ================================================================= Applicable Applicable Ratio of Funded Debt to Margin for Margin for EBITDA Base-Rate Euro-Rate Borrowings Borrowings ================================================================= 4.25 to 1.00 or more 1.00% 3.00% - ----------------------------------------------------------------- Less than 4.25 to 1.00, but 3.75 to 0.75% 2.75% 1.00 or more - ----------------------------------------------------------------- Less than 3.75 to 1.00, but 2.75 to 0.50% 2.50% 1.00 or more - ----------------------------------------------------------------- Less than 2.75 to 1.00, but 2.00 to 0.25% 2.25% 1.00 or more - ----------------------------------------------------------------- Less than 2.00 to 1.00 0.00% 2.00% ================================================================= For purposes of the definition of APPLICABLE MARGIN, EBITDA is calculated for the Companies' most recently-completed-four-fiscal quarters, and Funded Debt is determined as of the last day of that four-fiscal-quarter period. The calculation of EBITDA for any period before the date of this agreement shall be made on the basis of the combined Financials, before the date of this agreement, of US Borrower and of UK Borrowers and their Subsidiaries to the extent acquired by US Borrower in the Electrotech Acquisition. From the date of this agreement through the date that Administrative Agent receives the Current Financials and Compliance Certificate for the year ending December 31, 1996, the Applicable Margin is deemed to be 2.50% for Euro-Rate Borrowings and 0.50% for Base-Rate Borrowings. After Administrative Agent's receipt of the Current Financials and Compliance Certificate for the year ending December 31, 1996, the Applicable Margin in effect at any time (whether in the middle of an Interest Period or otherwise) is based upon the ratio of the Companies' Funded Debt to EBITDA as determined from the Current Financials and related Compliance Certificate then most recently received by Administrative Agent, effective as of the date received by Administrative Agent. If US Borrower fails to timely furnish to Administrative Agent any Financials and related Compliance Certificate as required by this agreement, then the maximum Applicable Margin applies from the date those Financials and related Compliance Certificate are required to be delivered and remain in effect until US Borrower furnishes them to Administrative Agent.

SECTION US FACILITY. - -------- ----------- COMMITMENT.

Credit Agreement ---------------- 19 .No such Borrowing is permitted that would cause the US-Facility- Commitment Usage (whether direct or participated) owed to any Lender under the US Facility to exceed that Lender's US-Facility Commitment. The foregoing limitations are conditions to Borrowings under the US Facility, the exceeding of which results in mandatory prepayments becoming due under SECTION 4.2(C). However, any such excess is part of the US Obligation for all purposes, including, without limitation, US Borrower's obligations to pay same in accordance with the Loan Documents. BORROWING PROCEDURE. The following procedures apply to Borrowings ------------------- under the US Facility: BORROWING REQUEST. US Borrower may request a Borrowing under the ----------------- US Facility by making or delivering a Borrowing Request to Administrative Agent, which is irrevocable and binding on US Borrower, which must state the Type, amount, and Interest Period for the Borrowing, and which must be received by Administrative Agent no later than (i) 10:00 a.m. on the third Business Day before the Borrowing Date for any Euro-Rate Borrowing, or (ii) 11:00 a.m. on the Borrowing Date for any Base-Rate Borrowing. Administrative Agent shall promptly on the day received notify each Lender under the US Facility about the contents of the Borrowing Request. FUNDING. Each Lender under the US Facility shall remit its ------- Commitment Percentage under the US Facility of each requested Borrowing under the US Facility to Administrative Agent's principal office in Dallas, Texas, in funds that are available for immediate use by Administrative Agent by 2:00 p.m. on the applicable Borrowing Date. Subject to receipt of those funds, Administrative Agent shall (unless to its actual knowledge any of the applicable conditions precedent have not been satisfied by US Borrower or waived by the requisite Lenders) make those funds available to US Borrower by (at US Borrower's option according to the related Borrowing Request) (i) wiring the funds to or for the account of US Borrower at the direction of US Borrower or (ii) depositing the funds in US Borrower's account with Administrative Agent. FUNDING ASSUMED. Absent contrary written notice from a Lender --------------- under the US Facility, Administrative Agent may assume that each such Lender has made its Commitment Percentage under the US Facility of the requested Borrowing available to Administrative Agent on the applicable Borrowing Date, and Administrative Agent may, in reliance upon that assumption (but shall not be required to), make available to US Borrower a corresponding amount. If any such Lender fails to make its Commitment Percentage under the US Facility of any requested Borrowing available to Administrative Agent on the applicable Borrowing Date, then 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 Fed-Funds Rate, or (ii) if that Lender fails to pay its amount upon demand, then from US Borrower together with interest at the rate applicable to that Borrowing. No Lender under the US Facility is responsible for the failure of any other Lender under the US Facility to make its Commitment Percentage of the US Facility of any Borrowing available as required by SECTION 2.2(B); however, failure of any Lender under the US Facility to make its Commitment Percentage of the US Facility of any Borrowing so available does not excuse any other Lender under the US Facility from making its Commitment Percentage of the US Facility of any Borrowing so available. Credit Agreement ---------------- 20 LC SUBFACILITY. -------------- (a) CONDITIONS. Subject to the provisions of the Loan Documents, the ---------- Issuer for the LC Subfacility agrees, if requested by US Borrower, to issue LCs upon US Borrower's delivering a LC Request and a LC Agreement, both of which must be received by that Issuer no later than the second Business Day before the Business Day on which the requested LC is to be issued, subject to the following conditions: . LCs may only be issued on or after the Closing Date for the US Facility and must expire on or before three Business Days before the Termination Date. . Each LC must be in the face amount of at least $100,000. . No such LC may be issued that would cause the LC Exposure to exceed the amount of the LC Subfacility. . No such LC may be issued that would cause the US-Facility Commitment Usage to exceed the lesser of either the total US- Facility Commitments or the Borrowing Base for the US Facility. . No such LC may be issued that would cause the US-Facility- Commitment Usage (whether direct or participated) owed to that Issuer under the US Facility to exceed that Issuer's US-Facility Commitment. The foregoing limitations are conditions to LCs under the LC Subfacility, the exceeding of which results in mandatory prepayments becoming due under SECTION 4.2(c). However, any such excess is part of the US Obligation for all purposes, including, without limitation, US Borrower's obligations to pay same in accordance with the Loan Documents. (b) PARTICIPATION. Immediately upon that Issuer's issuance of a LC, ------------- that Issuer shall be deemed to have sold and transferred to each other Lender under the US Facility, and each other such Lender shall be deemed irrevocably and unconditionally to have purchased and received from that Issuer, without recourse or warranty, an undivided interest and participation to the extent of such Lender's Commitment Percentage under the US Facility in the LC and all applicable Rights of that Issuer in the LC (other than Rights to receive certain fees provided in SECTION 5.4 to be for that Issuer's sole account). The Issuer shall as soon as practicable advise Administrative Agent who shall as soon as practicable advise the Lenders under the US Facility of any such issuance and their relative participations. (c) REIMBURSEMENT OBLIGATION. To induce that Issuer to issue and ------------------------ maintain LCs, and to induce the Lenders under the US Facility to participate in issued LCs, US Borrower agrees to pay or reimburse that Issuer (i) on the first Business Day after the Issuer notifies Administrative Agent and US Borrower that it has made payment under a LC, the amount paid by the Issuer and (ii) within five Business Days after demand, the amount of any additional costs, expenses, and fees that Issuer customarily charges for amending LC Agreements, for honoring drafts under letters of credit, and for taking similar action in connection with letters of credit. If US Borrower has not reimbursed the Issuer for any drafts paid by the date on which reimbursement is required under this section, then Administrative Agent is irrevocably authorized to fund US Borrower's reimbursement obligations as a Base-Rate Borrowing under the US Facility if proceeds are available under the US Facility and if the conditions in this agreement for such a US Borrowing Credit Agreement ---------------- 21 (other than any notice requirements or minimum funding amounts) have, to Administrative Agent's knowledge, been satisfied. The proceeds of that Borrowing shall be advanced directly to the Issuer to pay US Borrower's unpaid reimbursement obligations. If funds cannot be advanced under the US Facility, then US Borrower's reimbursement obligation shall constitute a demand obligation. US Borrower's obligations under this section are absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim, or defense to payment that US Borrower may have at any time against the Issuer or any other Person. From the date that the Issuer pays a draft under a LC until US Borrower either reimburses or is obligated to reimburse the Issuer for that draft under this section, the amount of that draft bears interest payable to the Issuer at the rate then applicable to Base-Rate Borrowings. From the due date of the respective amounts due under this section, to the date paid (including any payment from proceeds of a Base-Rate Borrowing), unpaid reimbursement amounts accrue interest that is payable on demand at the Default Rate. (d) GENERAL. The Issuer under the LC Subfacility shall promptly ------- notify Administrative Agent and US Borrower of the date and amount of any draft presented for honor under any LC (but failure to give notice will not affect US Borrower's obligations under this agreement). The Issuer shall pay the requested amount upon presentment of a draft unless presentment on its face does not comply with the terms of the applicable LC. When making payment, the Issuer may disregard (i) any default or potential default that exists under any other agreement and (ii) obligations under any other agreement that have or have not been performed by the beneficiary or any other Person (and the Issuer is not liable for any of those obligations). US Borrower's reimbursement obligations to the Issuer, and the Lenders under the US Facility, and each such Lender's obligations to the Issuer, under this section are absolute and unconditional irrespective of, and the Issuer is not responsible for (i) the validity, enforceability, sufficiency, accuracy, or genuineness of documents or endorsements (even if they are in any respect invalid, unenforceable, insufficient, inaccurate, fraudulent, or forged) except as otherwise provided in CLAUSE (f) below, (ii) any dispute by any Company with or any Company's claims, setoffs, defenses, counterclaims, or other Rights against the Issuer, any Lender, or any other Person, or (iii) the occurrence of any Potential Default or Event of Default. The Issuer shall promptly pay to Administrative Agent reimbursement payments received from US Borrower for Administrative Agent to promptly distribute to all Lenders under the US Facility according to their respective Commitment Percentages under the US Facility. (e) LENDERS' OBLIGATIONS. If US Borrower fails to reimburse the -------------------- Issuer as provided in SECTION 2.3(c) by the date on which reimbursement is due under that section, and funds cannot be advanced under the US Facility to satisfy the reimbursement obligations, then Administrative Agent shall promptly notify each Lender under the US Facility of that failure, of the date and amount paid, and of each such Lender's Commitment Percentage under the US Facility of the unreimbursed amount. Each such Lender shall promptly and unconditionally make available to Administrative Agent in immediately available funds its Commitment Percentage under the US Facility of the unpaid reimbursement obligation. Funds are due and payable to Administrative Agent before the close of business on the Business Day when Administrative Agent gives notice to each such Lender of US Borrower's reimbursement failure (if notice is given before 1:00 p.m.) or on the next succeeding Business Day (if notice is given after 1:00 p.m.). All amounts payable by any such Lender accrue interest after the due date at the Fed- Funds Rate from the day the applicable draft or draw is paid by Administrative Agent to (but not including) the date the amount is paid by that Lender to Administrative Agent. Upon receipt of those funds, Administrative Agent shall make them available to the Issuer. Credit Agreement ---------------- 22 (f) ISSUER'S DUTIES. The Issuer under the LC Subfacility agrees with --------------- US Borrower and each Lender under the US Facility 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. Each such Lender and US Borrower agree that, in paying any draft under any LC, the Issuer has no responsibility to obtain any document (other than any documents expressly 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 it. Neither the Issuer nor its Representatives will be liable to any such 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 the Issuer or any of its Representatives 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 applicable Governmental Requirements and in accordance with the standards of care specified in the Uniform Customs and Practices for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500 (as amended or modified), is binding upon the Companies and Lenders and, except as provided in SECTION 2.3(e), does not place that Issuer or any of its Representatives under any resulting liability to any Company or any Lender. Administrative Agent is not liable to any Company or any Lender for any action taken or omitted, in the absence of gross negligence or willful misconduct, by that Issuer or its Representative in connection with any LC. (g) CASH COLLATERAL. On the Termination Date and if requested by the --------------- Lenders under the US Facility while an Event of Default exists, US Borrower shall provide Administrative Agent, for the benefit of Lenders under the US Facility, cash collateral in an amount to equal the then-existing LC Exposure (with interest on that cash collateral accruing to the benefit of US Borrower). (h) INDEMNIFICATION. US BORROWER SHALL PROTECT, INDEMNIFY, PAY, AND --------------- SAVE ADMINISTRATIVE AGENT, THE ISSUER UNDER THE LC SUBFACILITY, AND EACH OTHER LENDER UNDER THE US FACILITY, AND THEIR RESPECTIVE REPRESENTATIVES HARMLESS FROM AND AGAINST ANY AND ALL CLAIMS, DEMANDS, LIABILITIES, DAMAGES, COSTS, CHARGES, AND EXPENSES (INCLUDING REASONABLE ATTORNEYS' FEES) WHICH ANY OF THEM MAY INCUR OR BE SUBJECT TO AS A CONSEQUENCE OF THE ISSUANCE OF ANY LC, ANY DISPUTE ABOUT IT, OR THE FAILURE OF ANY ISSUING LENDER TO HONOR A DRAW REQUEST UNDER ANY 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 UNDER THE FOREGOING FOR ITS OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. (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 each LC are part of the US Obligation, only the events specified in this agreement as an Event of Default shall constitute a default under any LC Agreement, and the terms of this agreement control any conflict between the terms of this agreement and any LC Agreement. 2.4 REQUESTS. Each Borrowing Request under the US Facility and LC Request -------- constitutes a representation and warranty by US Borrower that as of the Borrowing Date or the date of issuance of the requested LC, as the case may be, all of the applicable conditions precedent in SECTION 7.1 have been satisfied. Credit Agreement ---------------- 23 2.5 TERMINATION. US Borrower may -- upon giving at least five Business ----------- Days prior written and irrevocable notice to Administrative Agent -- terminate all or part of the US Facility. US Borrower may not, however, terminate all of the US Facility without Administrative Agent's prior written consent unless the UK Facility is concurrently terminated in accordance with SECTION 3.6. Each partial termination must be in an amount of not less than $1,000,000 or a greater integral multiple of $1,000,000 and must be ratable in accordance with the Commitment Percentage of each Lender under the US Facility. At the time of any termination, US Borrower shall pay to Administrative Agent, for the account of each Lender under the US Facility, as applicable, any amounts that may then be due under SECTION 4.2(c)(i), all accrued and unpaid fees under this agreement, the interest attributable to the amount of that termination, and any related Funding Loss. Any part of the US-Facility Commitments that are terminated may not be reinstated. SECTION 3 UK FACILITY. - --------- ----------- 3.1 COMMITMENT. Subject to the provisions in the Loan Documents, each ---------- Lender under the UK Facility severally but not jointly agrees to lend to UK Borrowers that Lender's UK-Revolving-Commitment Percentage of requested or required Borrowings under the UK Facility (other than under the Overdraft Subfacility) which UK Borrowers may borrow, repay, and reborrow under this agreement subject to the following conditions: . Each Borrowing under the UK Facility may only occur on a Business Day on or after the Closing Date for the UK Facility and before the Termination Date. . Each such Borrowing shall be due and payable on the last day of the relevant Interest Period. . Each such Borrowing may be denominated in Dollars or -- subject to SECTION 3.2(D) -- an Alternative Currency and shall be a minimum amount of $2,000,000 (or the equivalent in that Alternative Currency and a round amount in that Alternative Currency as is acceptable to Administrative Agent) or a greater integral multiple of $1,000,000 (or the equivalent in that Alternative Currency and a round amount in that Alternative Currency as is acceptable to Administrative Agent). . No such Borrowing is permitted that would cause the UK-Facility- Commitment Usage (calculated at the then-Dollar Equivalent of that amount) to exceed the lesser of either the total UK-Facility Commitments or the Borrowing Base for the UK Facility. . No such Borrowing is permitted that would cause the UK-Facility- Commitment Usage (calculated at the then-Dollar Equivalent of that amount) (whether direct or participated) owed to any Lender under the UK Facility to exceed that Lender's UK-Facility Commitment. The foregoing limitations are conditions to Borrowings under the UK Facility, the exceeding of which results in mandatory prepayments becoming due under SECTION 4.2(c). However, any such excess is part of the UK Obligation for all purposes, including, without limitation, UK Borrowers' joint and several obligations to pay same in accordance with the Loan Documents. 3.2 BORROWING PROCEDURE. The following procedures apply to Borrowings ------------------- under the UK Facility other than Borrowings under the Overdraft Subfacility: Credit Agreement ---------------- 24 (a) BORROWING REQUEST. UK Borrowers may request a Borrowing under ----------------- the UK Facility by making or delivering a Borrowing Request to Administrative Agent, which is irrevocable and binding on UK Borrowers, which must state which UK Borrower is to receive that Borrowing and state the currency (Dollars, Pound Sterling, Deutsche Marks or other Alternative Currency), amount, and Interest Period for each Borrowing under the UK Facility, and which must be received by Administrative Agent no later than 10:00 a.m. on the third Business Day before the Borrowing Date. Administrative Agent shall promptly on the day received notify each Lender under the UK Facility about the contents of the Borrowing Request. (b) FUNDING. Each Lender under the UK Facility shall remit its UK- ------- Revolving-Commitment Percentage of each requested Borrowing under the UK Facility to Administrative Agent's principal office in Dallas, Texas (or, at Administrative Agent's discretion and only in respect of the UK Facility, to an account of Administrative Agent with a bank in the United Kingdom that Administrative Agent may from time to time designate by written notice to UK Borrowers and the Lenders under the UK Facility), in funds that are available for immediate use by Administrative Agent by 2:00 p.m. (London time) on the applicable Borrowing Date in the currency requested. Subject to receipt of those funds, Administrative Agent shall (unless to its actual knowledge any of the applicable conditions precedent have not been satisfied by UK Borrowers or waived by the requisite Lenders under the UK Facility) make those funds available to the designated UK Borrower by wiring the funds to or for the account of the designated UK Borrower at the direction of the designated UK Borrower. (c) FUNDING ASSUMED. Absent contrary written notice from a Lender --------------- under the UK Facility, Administrative Agent may assume that each such Lender has made its UK-Revolving-Commitment Percentage of the requested Borrowing available to Administrative Agent on the applicable Borrowing Date, and Administrative Agent may, in reliance upon that assumption (but shall not be required to), make available to the designated UK Borrower a corresponding amount. If any such Lender fails to make its UK-Revolving- Commitment Percentage of any requested Borrowing available to Administrative Agent on the applicable Borrowing Date, then 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 Fed-Funds Rate, or (ii) if that Lender fails to pay its amount upon demand, then from UK Borrowers (on a joint and several basis) together with interest at the rate applicable to that Borrowing. No Lender under the UK Facility is responsible for the failure of any other Lender under the UK Facility to make its UK-Revolving- Commitment Percentage of any Borrowing available as required by SECTION 3.2(b); however, failure of any such Lender to make its UK-Revolving- Commitment Percentage of any Borrowing so available does not excuse any other Lender under the UK Facility from making its UK-Revolving-Commitment Percentage of any Borrowing so available. (d) CONDITIONS FOR ALTERNATIVE CURRENCIES. A Borrowing under the UK ------------------------------------- Facility (other than under the Overdraft Subfacility) may not be denominated in an Alternative Currency unless Administrative Agent has confirmed to UK Borrowers that such Alternative Currency is available for such Borrowings. If no later than 10:00 a.m. on the second Business Day before the Borrowing Date for a Borrowing in an Alternative Currency a Lender under the UK Facility notifies Administrative Agent that: (i) the Lender cannot fund its share of that Borrowing in the proposed Alternative Currency; or Credit Agreement ---------------- 25 (ii) an authorization of a Governmental Authority is required in respect of that Alternative Currency to permit its use by the Lender to make its share of that Borrowing available; or (iii) the use of that Alternative Currency is restricted or prohibited, then Administrative Agent shall notify UK Borrowers and each Lender under the UK Facility by 1:00 p.m. on the same day and that Borrowing shall not be made, and UK Borrowers are jointly and severally liable for any resulting Funding Loss. If no such notice is so given, then the Borrowing shall be made as requested subject to the other terms and conditions of the Loan Documents. 3.3 OVERDRAFT SUBFACILITY. Subject to the terms of this agreement and --------------------- only if no Event of Default or Potential Default exists, the Overdraft Subfacility is available for utilization by either UK Borrower until the earlier of either the Termination Date or any earlier date on which Overdraft Lender terminates the Overdraft Subfacility by notice to UK Borrowers and Administrative Agent. The Overdraft Subfacility shall be made available on such terms as shall be agreed between Overdraft Lender and UK Borrowers from time to time that are not inconsistent with the other terms of this agreement so long as: . Each UK Borrower shall complete such mandate and other like documents in respect of the Overdraft Subfacility as Overdraft Lender may reasonably require and that are not inconsistent with the other terms of this agreement. . None of the Overdraft Subfacility may be utilized that would cause the UK-Facility-Commitment Usage (calculated at then-Dollar Equivalent of that amount) to exceed the lesser of either the total UK-Facility Commitments or the Borrowing Base for the UK Facility. . None of the Overdraft Subfacility may be used that would cause the UK- Facility-Commitment Usage (calculated at then-Dollar Equivalent of that amount) for Overdraft Lender to exceed its UK-Facility Commitment. . None of the Overdraft Subfacility may be utilized that would cause the limitations in the definition of the Overdraft Subfacility to be exceeded. The foregoing limitations are conditions to overdrafts and other accommodations under the Overdraft Subfacility, the exceeding of which results in mandatory prepayments becoming due under SECTION 4.2(c). However, any such excess is part of the UK Obligation for all purposes, including, without limitation, UK Borrowers' joint and several obligations to pay same in accordance with the Loan Documents. For the avoidance of doubt, Overdraft Lender may, without liability, return cheques unpaid if the payment of those cheques would result in a breach of the foregoing limitations. Subject to the foregoing conditions, Overdraft Lender agrees to make the Overdraft Subfacility available on a revolving basis to UK Borrowers to be utilized on any business day in London by way of overdraft on usual banking terms (including that amounts outstanding by way of overdraft are repayable on demand and are subject to agreement between Overdraft Lender and UK Borrowers), whether by way of BACS facilities and such other facilities or financial accommodation as each case on such terms (not inconsistent with the other terms of this agreement) as Overdraft Lender and UK Borrowers may from time to time agree. Credit Agreement ---------------- 26 3.4 BG/LC SUBFACILITY. ----------------- (a) CONDITIONS. Subject to the provisions of the Loan Documents, the ---------- Issuer for the BG/LC Subfacility agrees, if requested by UK Borrowers, to issue BGs (if it may lawfully do so) or LCs upon UK Borrowers delivering a BG/LC Request and, if applicable, a LC Agreement, both of which must be received by Administrative Agent and that Issuer no later than the second Business Day before the Business Day on which the requested BG or LC is to be issued, subject to the following conditions: . BGs and LCs may only be issued on or after the Closing Date for the UK Facility and must expire on or before three Business Days before the Termination Date. . There may be no more than 20 outstanding BGs and LCs, collectively, at any time. . Each LC and BG must state on its face its expiry date and the maximum amount available and otherwise be in form and substance acceptable to the Issuer and Administrative Agent. . No such BG or LC may be issued that would cause the BG/LC Exposure (calculated at then-Dollar Equivalent of that amount) to exceed the amount of the BG/LC Subfacility. . No such BG or LC may be issued that would cause the UK-Facility- Commitment Usage (calculated at then-Dollar Equivalent of that amount) to exceed the lesser of either the total UK-Facility Commitments or the Borrowing Base for the UK Facility. . No such BG or LC may be issued that would cause the UK-Facility- Commitment Usage (calculated at then-Dollar Equivalent of that amount) (whether direct or participated) owed to that Issuer under the UK Facility to exceed that Issuer's UK-Facility Commitment. The foregoing limitations are conditions to BGs and LCs under the BG/LC Subfacility, the exceeding of which results in mandatory prepayments becoming due under SECTION 4.2(c). However, any such excess is part of the UK Obligation for all purposes, including, without limitation, UK Borrowers' joint and several obligations to pay same in accordance with the Loan Documents. The Issuer shall as soon as practicable advise Administrative Agent who shall as soon as practicable advise the Lenders under the UK Facility of any such issuance. (b) REIMBURSEMENT OBLIGATION. To induce that Issuer to issue and ------------------------ maintain BGs or LCs, UK Borrowers jointly and severally agree to pay or reimburse the Issuer (i) on the first Business Day after the Issuer notifies Administrative Agent and UK Borrowers that it has made payment under a BG or LC, the amount paid by that Issuer and (ii) within five Business Days after demand, the amount of any additional costs, expenses, and fees that Issuer customarily charges for amending LC Agreements, for honoring drafts under bank guarantees or letters of credit, and for taking similar action in connection with bank guarantees or letters of credit. If UK Borrowers have not reimbursed the Issuer for any drafts paid by the date on which reimbursement is required under this section, then Administrative Agent is irrevocably authorized to fund the UK Borrowers' reimbursement obligations as a Borrowing under the UK Facility if proceeds are available under the UK Facility and if the conditions in this agreement for such a Borrowing under the UK Facility (other than any notice requirements or minimum funding amounts) have, to Administrative Agent's knowledge, been satisfied. The proceeds of that Borrowing shall be advanced directly to the Issuer to pay UK Borrowers' unpaid reimbursement obligations. If funds cannot be advanced under the UK Facility, then UK Borrowers' Credit Agreement ---------------- 27 reimbursement obligation shall constitute a demand obligation. UK Borrowers' obligations under this section are absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim, or defense to payment that either UK Borrower may have at any time against the Issuer or any other Person. From the date that the Issuer pays a draft under a BG or LC until the UK Borrowers either reimburse or are obligated to reimburse the Issuer for that draft under this section, the amount of that draft bears interest payable to the Issuer at an annual interest rate equal to the sum of the Issuer's cost of funds, plus the Applicable Margin for Euro-Rate Borrowings, plus the applicable Mandatory- Liquid-Assets Costs. From the due date of the respective amounts due under this section, to the date paid (including any payment from proceeds of a Borrowing), unpaid reimbursement amounts accrue interest that is payable on demand at the Default Rate. (c) GENERAL. The Issuer under the BG/LC Subfacility shall promptly ------- notify Administrative Agent and UK Borrowers of the date and amount of any draft presented for honor under any BG or LC (but failure to give notice will not affect UK Borrowers' obligations under this agreement). The Issuer shall pay the requested amount upon presentment of a draft unless presentment on its face does not comply with the terms of the applicable BG or LC. When making payment, that Issuer may disregard (i) any default or potential default that exists under any other agreement and (ii) obligations under any other agreement that have or have not been performed by the beneficiary or any other Person (and that Issuer is not liable for any of those obligations). UK Borrowers' reimbursement obligations to the Issuer and the Lenders under the UK Facility, and each such Lender's obligations to the Issuer, under this section are absolute and unconditional irrespective of, and the Issuer is not responsible for (i) the validity, enforceability, sufficiency, accuracy, or genuineness of documents or endorsements (even if they are in any respect invalid, unenforceable, insufficient, inaccurate, fraudulent, or forged) except as otherwise provided in CLAUSE (e) below, (ii) any dispute by any Company with or any Company's claims, setoffs, defenses, counterclaims, or other Rights against the Issuer, any Lender, or any other Person, or (iii) the occurrence of any Potential Default or Event of Default. The Issuer shall promptly pay to Administrative Agent reimbursement payments received from either UK Borrower for Administrative Agent to promptly distribute to all Lenders under the UK Facility according to their respective UK-Revolving- Commitment Percentages. (d) LENDERS' OBLIGATIONS. If UK Borrowers fail to reimburse the -------------------- Issuer as provided in SECTION 3.4(b) by the date on which reimbursement is due under that section, and funds cannot be advanced under the UK Facility to satisfy the reimbursement obligations, then Administrative Agent shall promptly notify each Lender under the UK Facility of that failure, of the date and amount paid, and of each such Lender's UK-Revolving-Commitment Percentage of the unreimbursed amount. Each Lender under the UK Facility shall promptly and unconditionally make available to Administrative Agent in immediately available funds its UK-Revolving-Commitment Percentage of the unpaid reimbursement obligation, whereupon, subject to receipt of those funds, Administrative Agent shall make them available to the Issuer. Funds are due and payable to Administrative Agent by the close of business (Dallas time) three Business Days after notification for amounts payable in Dollars, Deutsche Marks, or other Alternative Currency (other than Pound Sterling) and one Business Day after notification for amounts payable in Pound Sterling. All amounts payable by any Lender under the UK Facility accrue interest after the due date at the Fed-Funds Rate from the day the applicable draft or draw is paid by Administrative Agent to (but not including) the date the amount is paid by that Lender to Administrative Agent. Upon receipt of those funds, Administrative Agent shall make them available to the Issuer. Credit Agreement ---------------- 28 (e) ISSUER'S DUTIES. The Issuer under the BG/LC Subfacility agrees --------------- with each Lender and each UK Borrower under the UK Facility that it will exercise and give the same care and attention to each BG or LC that it issues as it gives to its other bank guarantees and letters of credit. Each such Lender and UK Borrowers agree that, in paying any draft under any BG or LC, the Issuer has no responsibility to obtain any document (other than any documents expressly required by the respective BG or LC) or to ascertain or inquire as to any document's validity, enforceability, sufficiency, accuracy, or genuineness or the authority of any Person delivering it. Neither the Issuer nor its Representatives will be liable to any such Lender or any Company for any BG's or LC's use or for any beneficiary's acts or omissions. Any action, inaction, error, delay, or omission taken or suffered by the Issuer or any of its Representatives in connection with any BG or 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 applicable Governmental Requirements and in accordance with the standards of care specified in the Uniform Customs and Practices for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500 (as amended or modified), is binding upon the Companies and Lenders and, except as provided in SECTION 3.4(d), does not place the Issuer or any of its Representatives under any resulting liability to any Company or any Lender. Administrative Agent is not liable to any Company or any Lender for any action taken or omitted, in the absence of gross negligence or willful misconduct, by the Issuer or its Representative in connection with any BG or LC. (f) CASH COLLATERAL. On the Termination Date and if requested by the --------------- Lenders under the UK Facility while an Event of Default exists, UK Borrowers shall provide Administrative Agent, for the benefit of Lenders under the UK Facility, cash collateral in an amount to equal the then- existing BG/LC Exposure (with interest on that cash collateral accruing to the benefit of UK Borrowers). (g) INDEMNIFICATION. UK BORROWERS SHALL JOINTLY AND SEVERALLY --------------- PROTECT, INDEMNIFY, PAY, AND SAVE ADMINISTRATIVE AGENT, THE ISSUER UNDER THE BG/LC SUBFACILITY, AND EACH OTHER LENDER UNDER THE UK FACILITY, AND THEIR RESPECTIVE REPRESENTATIVES HARMLESS FROM AND AGAINST ANY AND ALL CLAIMS, DEMANDS, LIABILITIES, DAMAGES, COSTS, CHARGES, AND EXPENSES (INCLUDING REASONABLE ATTORNEYS' FEES) WHICH ANY OF THEM MAY INCUR OR BE SUBJECT TO AS A CONSEQUENCE OF THE ISSUANCE OF ANY BG OR LC, ANY DISPUTE ABOUT IT, OR THE FAILURE OF THE ISSUER TO HONOR A DRAW REQUEST UNDER ANY BG OR 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 UNDER THE FOREGOING FOR ITS OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. (h) 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 BG and LC are as provided in this agreement, drafts under each BG and LC are part of the UK Obligation, only the events specified in this agreement as an Event of Default shall constitute a default in respect of any BG and LC, and the terms of this agreement control any conflict between the terms of this agreement and any LC Agreement. 3.5 REQUESTS. Each Borrowing Request under the UK Facility, borrowing or -------- other accommodation under the Overdraft Subfacility, and BG/LC Request constitutes a joint and several representation and warranty by UK Borrowers that as of the Borrowing Date, the date of issuance of the Credit Agreement ---------------- 29 requested BG or LC, or the date of the borrowing or accommodation, as the case may be, that all of the applicable conditions precedent in SECTION 7.2 have been satisfied. 3.6 TERMINATION. UK Borrowers may -- upon giving at least five Business ----------- Days prior written and irrevocable notice to Administrative Agent -- terminate all or part of the UK Facility. UK Borrowers may not terminate all of the UK Facility without Administrative Agent's prior written consent unless the US Facility is concurrently terminated in accordance with SECTION 2.5. Each partial termination must (a) be in an amount of not less than the Dollar Equivalent of $1,000,000 or a greater integral multiple of the Dollar Equivalent of $1,000,000, (b) be ratable in accordance with each Lender's UK-Revolving- Commitment Percentages, and (c) be accompanied by a concurrent partial termination of the Overdraft Subfacility in the same ratio as the partial termination of the overall UK Facility. At the time of any termination, UK Borrower shall pay to Administrative Agent, for the account of each Lender under the UK Facility, as applicable, any amounts that may then be due under SECTION 4.2(c)(ii), all accrued and unpaid fees under this agreement, the interest attributable to the amount of that termination, and any related Funding Loss. Any part of the UK-Facility Commitments that are terminated may not be reinstated. 3.7 JOINT AND SEVERAL. UK Borrowers are jointly and severally liable for ----------------- the UK Obligation. The failure of either UK Borrower to perform its obligations under any of the Loan Documents shall not affect the obligations of the other UK Borrower, and the effectiveness of the Loan Documents shall not be revoked or impaired as to either UK Borrower by any contingency affecting the other UK Borrower, by the revocation or release of any obligation thereunder of either UK Borrower, by any time or any indulgence granted to either UK Borrower, or by any variation or amendment to the terms of any of the Loan Documents. SECTION 4 PAYMENT TERMS. - --------- ------------- 4.1 NOTES AND PAYMENTS. ------------------ (a) NOTES. The Principal Debt of the US Facility and interest on it ----- are evidenced by the US-Facility Notes, one payable to each Lender under the US Facility. The Principal Debt of the UK Facility (other than under the Overdraft Subfacility) and interest on it are evidenced by the UK- Facility Notes, one payable to each Lender under the UK Facility. (b) PAYMENT. UK Borrowers must make each payment and prepayment ------- under the Overdraft Subfacility directly to Overdraft Lender in funds available for immediate use by Overdraft Lender by 1:00 p.m. (London time) on the day due. Each Borrower must make each payment and prepayment it owes under the Loan Documents to Administrative Agent's principal office in Dallas, Texas (or, at Administrative Agent's discretion and only in respect of the UK Facility, to an account of Administrative Agent with a bank in the United Kingdom that Administrative Agent may from time to time designate by written notice to UK Borrowers and the Lenders under the UK Facility) in funds available for immediate use by Administrative Agent by 1:00 p.m. on the day due. Subject to SECTION 4.8, any funds not received by the applicable deadline on any day in the preceding two sentences shall continue to accrue interest as if they were received on the next Business Day. Administrative Agent shall promptly pay to each Lender the part of any payment or prepayment to which that Lender is entitled under this agreement on the same day Administrative Agent receives the funds from any Borrower. (c) PAYMENT ASSUMED. Unless Administrative Agent has received notice --------------- from a Borrower before the date on which any payment or prepayment is due under this agreement that Credit Agreement ---------------- 30 US Borrower will not make that payment or prepayment in full, then Administrative Agent may assume that US Borrower to have made the full payment or prepayment due and may (in reliance upon that assumption and without any obligation to) cause to be distributed to each relevant Lender on that date the amount then due to each relevant Lender in respect of that payment or prepayment. If and to the extent US Borrower does not make the full payment or prepayment due to Administrative Agent, each relevant Lender receiving any portion of it shall repay to Administrative Agent on demand the amount distributed to that Lender by Administrative Agent together with interest for each day from the date that Lender received payment from Administrative Agent until the date that Lender repays Administrative Agent (unless such repayment is made on the same day as such distribution), at an interest rate equal to the Fed-Funds Rate. 4.2 INTEREST AND PRINCIPAL PAYMENTS. ------------------------------- (a) INTEREST PAYMENTS. Accrued interest on each Euro-Rate Borrowing ----------------- is due and payable on the last day of its respective Interest Period. If any Interest Period for a Euro-Rate Borrowing is greater than three months, then accrued interest is also due and payable on the date three months after the commencement of the Interest Period. Accrued interest on each Base-Rate Borrowing is due and payable on the last day of each March, June, September, and December -- commencing on the first of those dates that follows the applicable Closing Date -- and on the Termination Date. Accrued interest on the Overdraft Subfacility is payable on demand. (b) PRINCIPAL PAYMENTS. The Principal Debt of Borrowings under the ------------------ Overdraft Subfacility are due and payable as provided in SECTION 3.3. Each Euro-Rate Borrowing under the UK Facility is due and payable on the earlier of either the Termination Date or the last day of its applicable Interest Period. All Principal Debt is due and payable on the Termination Date. (c) PREPAYMENTS. ----------- (i) Upon demand, US Borrower shall make a mandatory prepayment of Principal Debt of the US Facility at least in the amount of any Borrowing-Base Deficiency that may ever exist under the US Facility for whatever reason, including, without limitation, because of a downward fluctuation of the Borrowing Base for the US Facility or any partial reduction of the US-Facility Commitments. (ii) Upon demand, UK Borrowers shall jointly and severally make a mandatory prepayment of any combination of Principal Debt of the UK Facility or the Overdraft Exposure at least in the amount of any Borrowing-Base Deficiency that may ever exist under the UK Facility for whatever reason, including, without limitation, because of a downward fluctuation of the Borrowing Base for the UK Facility or any partial reduction of the UK-Facility Commitments. (iii) If Administrative Agent ever determines that, as a result of fluctuations in exchange rates, the Dollar Equivalent of the UK- Facility-Commitment Usage ever exceeds the total UK-Facility Commitments, then, upon demand, UK Borrowers shall jointly and severally make a mandatory prepayment of any combination of the Principal Debt of the UK Facility or the Overdraft Exposure at least in the amount of that excess. Any Lender under the UK Facility may request that Administrative Agent determine, in which event Administrative Agent shall promptly determine, the Dollar Equivalent of the UK-Facility-Commitment Usage for purposes of this CLAUSE (iii). Credit Agreement ---------------- 31 (iv) Any Borrower may at any time prepay, without penalty and in whole or in part, any of the Principal Debt for which it is obligated under the Loan Documents in amounts not less than either (i) the amount of any Euro-Rate Borrowing or (ii) otherwise the lesser of either (A) the Dollar Equivalent of $1,000,000 or greater integral multiples of the Dollar Equivalent of $1,000,000, or (B) the total unpaid balance of the Principal Debt of the US Facility or the UK Facility, as the case may be. (v) Upon demand (A) US Borrower shall pay any Funding Loss resulting from any prepayment of whatever nature of any of the Principal Debt of the US Facility, and (B) UK Borrowers shall jointly and severally pay any Funding Loss resulting from any prepayment of whatever nature of any of the Principal Debt of the UK Facility. (vi) Conversions under SECTION 4.10 are not prepayments. (d) REQUIRED CURRENCY. UK Borrowers shall make all principal, ----------------- interest, and other payments and prepayments for which they are obligated in the currency in which that obligation was originally denominated (the "REQUIRED CURRENCY"). However, the failure by UK Borrowers to make any payment or prepayment in any Required Currency (other than Dollars) on the date due solely because the Required Currency has ceased to be freely transferable and convertible into Dollars in the relevant interbank market shall not constitute an Event of Default if UK Borrowers pay (i) on that due date, the Dollar Equivalent (as calculated by Administrative Agent in good faith) of the amount of the Required Currency due on that date and (b) within ten days after demand through Administrative Agent by any Lender under the UK Facility, the amount that will (in the reasonable determination of that Lender) reimburse that Lender for any loss or expense caused by the failure of UK Borrowers to make that payment or prepayment in the Required Currency on the date due. That Lender shall submit a statement as to any such loss or expense (including calculations in reasonable detail) to Administrative Agent and UK Borrowers, which shall, in the absence of manifest error, be conclusive and binding on UK Borrowers. 4.3 INTEREST OPTIONS. Except that the Euro Rate may not be selected in ---------------- respect of the US Facility when an Event of Default or Potential Default exists and except as otherwise provided in this agreement, Borrowings bear interest at an annual rate equal to the lesser of either the Maximum Rate, or in respect of Borrowings under the: (a) US Facility, the sum of the Base Rate for the US Facility plus the Applicable Margin or the sum of the Euro Rate plus the Applicable Margin (in each case as designated or deemed designated by US Borrower for a Borrowing under the US Facility); (b) UK Facility, the sum (i) of the Euro Rate, plus (ii) the Applicable Margin, plus (iii) in respect of Borrowings in Pound Sterling, any Mandatory-Liquid-Assets Costs; and (c) Overdraft Subfacility, the sum of the Base Rate for the Overdraft Subfacility, plus the Applicable Margin. Each change in the applicable Base Rates and the Maximum Rate is effective, without notice to any Borrower or any other Person, upon the effective date of change. 4.4 RATE QUOTATIONS. Any Borrower may call Administrative Agent before --------------- delivering a Borrowing Request to receive an indication of the interest rates then in effect, but the indicated rates do Credit Agreement ---------------- 32 not bind Administrative Agent or any Lenders or affect the interest rate that is actually in effect when that Borrower makes a Borrowing Request or on the Borrowing Date. 4.5 DEFAULT RATE. If permitted by applicable Governmental Requirements, ------------ all past-due Principal Debt, past-due payment and reimbursement obligations in connection with BGs or LCs, and past-due interest accruing on any of the foregoing bears interest from the date due (stated or by acceleration) at the Default Rate until paid, regardless whether payment is made before or after entry of a judgment. 4.6 INTEREST RECAPTURE. If the designated interest rate applicable to any ------------------ Borrowing exceeds the Maximum Rate, the interest rate on that Borrowing is limited to the Maximum Rate, but any subsequent reductions in the designated rate shall not reduce the interest rate thereon below the Maximum Rate until the total amount of accrued interest equals the amount of interest that would have accrued if that designated rate had always been in effect. If at maturity (stated or by acceleration), or at final payment of any Note, the total interest paid or accrued is less than the interest that would have accrued if the designated rates had always been in effect, then, at that time and to the extent permitted by applicable Governmental Requirements, the Borrower or Borrowers obligated on that Note shall pay an amount equal to the difference between (a) the lesser of the amount of interest that would have accrued if the designated rates had always been in effect and the amount of interest that would have accrued if the Maximum Rate had always been in effect, and (b) the amount of interest actually paid or accrued on that Note. 4.7 INTEREST CALCULATIONS. Interest on the Overdraft Exposure and on --------------------- Borrowings denominated in Pound Sterling shall be calculated on the basis of actual number of days (including the first day but excluding the last day) elapsed over a 365- or 366-day year (as the case may be). All other interest shall be calculated on the basis of actual number of days elapsed (including the first day but excluding the last day) elapsed but computed as if each calendar year consisted of 360 days (unless the calculation would result in an interest rate greater than the Maximum Rate, in which event it will be computed on the basis of a year of 365 or 366 days, as the case may be). All interest rate determinations and calculations by Overdraft Lender in respect of the Overdraft Subfacility and otherwise by Administrative Agent are conclusive and binding absent manifest error. 4.8 MAXIMUM RATE. Regardless of any provision contained in any Loan ------------ Document, no Lender is entitled to contract for, charge, take, reserve, receive, or apply, as interest on all or any part of the US Obligation or UK Obligation, any amount in excess of the Maximum Rate, and, if any Lender ever does so, then any excess shall be treated as a partial prepayment of principal and any remaining excess shall be refunded to the appropriate Borrower or Borrowers. In determining if the interest paid or payable exceeds the Maximum Rate, Borrowers, Administrative Agent, and Lenders shall, to the maximum extent lawful, (a) treat all Borrowings under the US Facility as but a single extension of credit and all Borrowings under the UK Facility as but a single extension of credit (and Lenders, Administrative Agent, and Borrowers agree that is the case and that provision in this agreement for multiple Borrowings is for convenience only), (b) characterize any nonprincipal payment as an expense, fee, or premium rather than as interest, (c) exclude voluntary prepayments and their effects, and (d) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of this agreement. However, if the applicable Principal Debt is paid in full before the end of their full contemplated term, and if the interest received for its actual period of existence exceeds the Maximum Amount, each applicable Lender shall refund any excess (and may not, to the extent lawful, be subject to any penalties provided by any applicable laws for contracting for, charging, taking, reserving, or receiving interest in excess of the Maximum Amount). If Texas laws are applicable for purposes of determining the "Maximum Rate" or the "Maximum Amount," then those terms mean the "indicated rate ceiling" from time to time in effect under Article 5069- 1.04, Title 79, Revised Civil Statutes of Texas. Borrowers agree that Chapter 15, Credit Agreement ---------------- 33 Subtitle 79, Revised Civil Statutes of Texas, 1925 (which regulates certain revolving credit loan accounts and revolving triparty accounts), does not apply to the Loan Documents. 4.9 INTEREST PERIODS. When Borrower requests any Euro-Rate Borrowing, it ---------------- may elect the applicable Interest Period, subject to SECTION 17.1 and the following conditions: (a) The initial Interest Period for a Euro-Rate Borrowing commences on the applicable Borrowing Date or conversion date, and each subsequent Interest Period applicable to any Borrowing commences on the day when the next preceding applicable Interest Period expires; (b) if any Interest Period for a Euro-Rate Borrowing begins on a day for which no numerically corresponding Business Day in the calendar month at the end of the Interest Period exists, then the Interest Period ends on the last Business Day of that calendar month; (c) if a Borrower is required to pay any portion of a Euro-Rate Borrowing before the end of its Interest Period in order to comply with the payment provisions of the Loan Documents, then it shall also pay any related Funding Loss; and (d) no more than five Interest Periods may be in effect at one time for either the US Facility or the UK Facility. 4.10 CONVERSIONS. Subject to the applicable dollar limits of SECTION 2.1 ----------- and provided that US Borrower may not convert to or select a new Interest Period for a Euro-Rate Borrowing at any time when an Event of Default or Potential Default exists, US Borrower may (a) convert a Euro-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 Euro-Rate Borrowing, and (c) elect a new Interest Period for a Euro-Rate Borrowing. That election may be made by delivery to Administrative Agent a Conversion Notice by no later than 10:00 a.m. on the second Business Day before the conversion date or the last day of the Interest Period, as the case may be (for conversion to a Euro-Rate Borrowing or election of a new Interest Period), and no later than 11:00 a.m. on the last day of the Interest Period (for conversion to a Base-Rate Borrowing). Absent timely delivery of a Conversion Notice or if an Event of Default or Potential Default exists, then, each Euro-Rate Borrowing under the US Facility shall be deemed converted to a Base-Rate Borrowing effective when the applicable Interest Period expires. 4.11 ORDER OF APPLICATION. -------------------- (a) NO EVENT OF DEFAULT. Except as otherwise provided by any Loan ------------------- Document, if no Event of Default or Potential Default exists, then any payment or prepayment by (i) US Borrower shall be applied to the US Obligation in the order and manner as US Borrower shall direct and (ii) either UK Borrower shall be applied to the UK Obligation in the order and manner as that UK Borrower shall direct. (b) EVENT OF DEFAULT. If an Event of Default or Potential Default ---------------- exists or if the appropriate Borrower fails to give direction, then, except as provided in the last sentence of this paragraph, any payment (including proceeds from the exercise of any Rights) in respect of the US Obligation shall be applied to the US Obligation or in respect of the UK Obligation shall be applied to the UK Obligation, in each case, in the following order: (i) To all fees and expenses for which either applicable Agent or any applicable Lender has not been paid or reimbursed in accordance with the Loan Documents (and if that payment is less than all applicable unpaid or unreimbursed fees and expenses, then the payment shall be paid against applicable unpaid and unreimbursed fees and expenses in the order of incurrence or due date); (ii) to accrued interest on the applicable Principal Debt; (iii) to any applicable LC or BG/LC, as the case may be, reimbursement obligations that are due and payable and that remain unfunded by a Borrowing; (iv) to the remaining applicable Principal Debt in the order as Required Lenders may elect (but Required Lenders agree to apply proceeds in an order that will minimize any Funding Loss); (v) to the remaining US Obligation or UK Obligation, as the case may be, in the order and Credit Agreement ---------------- 34 manner Required Lenders deem appropriate; and (vi) as a deposit with Administrative Agent, for the benefit of Lenders, as security for and payment of any subsequent LC or BG/LC, as the case may be, reimbursement obligations. Notwithstanding the foregoing, upon any Event of Default, Overdraft Lender is entitled and instructed to first setoff against any of the Overdraft Balances all amounts outstanding under the Overdraft Subfacility (including without limitation, the Overdraft Differential) before the foregoing provisions become applicable; Overdraft Lender is entitled to retain for its own account the amount of that setoff up to but not in excess of the Overdraft Differential and shall otherwise share that setoff with Lenders under SECTION 4.12(b). (c) SEPARATE OBLIGATIONS. Nothing in CLAUSE (b) above requires or -------------------- permits any payment or prepayment of the US Obligation to be applied to any portion of the UK Obligation or any payment or prepayment of the UK Obligation to be applied to any portion of the US Obligation. (d) DISTRIBUTION TO LENDERS. Subject to the last sentence of CLAUSE ----------------------- (b) above, each payment or prepayment made under this SECTION 4 shall be distributed to each Lender in accordance with (i) before the Termination Date, its Commitment Percentage under the US Facility or its UK-Revolving- Commitment Percentage, as applicable, of that payment or prepayment, and (ii) on and after the Termination Date, its Default Percentage under the US Facility or the UK Facility, as applicable, of that payment or prepayment. 4.12 SHARING OF PAYMENTS. ------------------- (a) If any Lender under the US Facility obtains any payment or prepayment with respect to the US Obligation (whether voluntary, involuntary, or otherwise, including, without limitation, as a result of exercising its Rights under SECTION 4.13) that exceeds the part of that payment or prepayment that it is then entitled to receive under the Loan Documents, then that Lender shall purchase from the other Lenders under the US Facility participations that will cause the purchasing Lender to share the excess payment or prepayment ratably with each such other Lender in accordance with the Loan Documents. (b) If any Lender under the UK Facility obtains any payment or prepayment with respect to the UK Obligation (whether voluntary, involuntary, or otherwise, including, without limitation, as a result of exercising its Rights under the last sentence of SECTION 4.11(b) or SECTION 4.13) that exceeds the part of that payment or prepayment that it is then entitled to receive under the Loan Documents, then that Lender shall purchase from the other Lenders under the UK Facility participations that will cause the purchasing Lender to share the excess payment or prepayment ratably with each such other Lender in accordance with the Loan Documents. (c) If all or any portion of any excess payment or prepayment is subsequently recovered from a purchasing Lender under CLAUSE (a) or (b) above, then the purchase shall be rescinded and the purchase price restored to the extent of the recovery. (d) Each Borrower agrees that any Lender purchasing a participation from another Lender under this section may, to the fullest extent lawful, exercise all of its Rights of payment (including the Right of offset) with respect to that participation as fully as if that Lender were the direct creditor of that Borrower in the amount of that participation. 4.13 OFFSET. If an Event of Default has occurred and is then continuing ------ unwaived, each Lender is entitled to exercise (for the benefit of all Lenders in accordance with SECTION 4.12) the Rights of offset Credit Agreement ---------------- 35 and banker's Lien against each and every account and other property, or any interest therein, that any Company may now or hereafter have with, or which is now or hereafter in the possession of, that Lender to the extent of the full amount of the US Obligation or UK Obligation, as the case may be, owed (directly or participated) to it. 4.14 BOOKING BORROWINGS. To the extent permitted by applicable ------------------ Governmental Requirements, any Lender may make, carry, or transfer its share of Borrowings at, to, or for the account of any of its branch offices or the office or branch of any of its Affiliates, so long as no additional costs are incurred by any Borrower as a result thereof. However, no Affiliate or branch is entitled to receive any greater payment under SECTION 4.16 than the transferor Lender would otherwise have been entitled to receive with respect to those Borrowings, and a transfer may not be made if, as a direct result of it, SECTION 4.15, 4.17, 4.19(a), or 4.19(b) would apply to any of the US Obligations or UK Obligations, as the case may be. If any of the conditions of SECTIONS 4.16, 4.17, 4.19(a), or 4.19(b) ever apply to a Lender, that Lender shall, to the extent possible, carry or transfer its UK Borrowings at, to, or for the account of any of its branch offices or the office or branch of any of its Affiliates so long as the transfer is consistent with the other provisions of this section, does not create any burden or adverse circumstance for that Lender that would not otherwise exist, and eliminates or ameliorates the conditions of SECTIONS 4.16 or 4.17 as applicable. 4.15 BASIS UNAVAILABLE OR INADEQUATE FOR EURO RATE. If, on or before any --------------------------------------------- date when a Euro Rate is to be determined for a Borrowing, Administrative Agent reasonably determines that the basis for determining the applicable rate is not available or any Lender reasonably determines that the resulting rate does not accurately reflect the cost to that Lender of making or converting Borrowings at that rate for the applicable Interest Period, then Administrative Agent shall promptly notify Borrowers and Lenders of that determination (which is conclusive and binding on Borrowers absent manifest error) and the applicable Borrowing shall bear interest (a) in respect of the US Facility, at the sum of the Base Rate for the US Facility plus the Applicable Margin, and (b) in respect of each Lender under the UK Facility (other than under the Overdraft Subfacility) at the sum of the cost to that Lender of funding its participation in the UK Facility plus the Applicable Margin for Euro-Rate Borrowings plus any applicable Mandatory-Liquid-Assets Cost. Until Administrative Agent notifies US Borrower that those circumstances no longer exist, the commitments of the Lenders under the US Facility to make, or to convert to, Euro-Rate Borrowings, as the case may be, are suspended. 4.16 ADDITIONAL COSTS. ---------------- (a) RESERVES. With respect to any Euro-Rate Borrowing (i) if any -------- change in any present Governmental Requirement, any change in the interpretation or application of any present Governmental Requirement, or any future Governmental Requirement imposes, modifies, or deems applicable (or if compliance by any Lender with any requirement of any Governmental Authority results in) any requirement that any reserves (including, without limitation, any marginal, emergency, supplemental, or special reserves) be maintained (other than any reserve included in the Reserve Requirement), and if (ii) those reserves reduce any sums receivable by that Lender under this agreement or increase the costs incurred by that Lender in advancing or maintaining any portion of any Euro-Rate Borrowing, then (iii) that Lender (through Administrative Agent) shall deliver to the applicable Borrower or Borrowers a certificate setting forth in reasonable detail the calculation of the amount necessary to compensate it for its reduction or increase (which certificate is conclusive and binding absent manifest error), and (iv) that Borrower or those Borrowers shall pay that amount to that Lender within five days after demand. The provisions of and undertakings and indemnification in this CLAUSE (a) survive the satisfaction and payment of the US Obligation and UK Obligation and termination of this agreement. This CLAUSE (a) is Credit Agreement ---------------- 36 to be applied to avoid duplication and otherwise without prejudice to any Mandatory-Liquid-Assets Costs payable by any Borrower under this agreement. (b) CAPITAL ADEQUACY. With respect to any Borrowing, LC, or BG, if ---------------- any change in any present Governmental Requirement, any change in the interpretation or application of any present Governmental Requirement, or any future Governmental Requirement regarding capital adequacy, or if compliance by any Lender with any request, directive, or requirement imposed in the future by any Governmental Authority regarding capital adequacy, or if any change in its written policies or in the risk category of this transaction, in any of the foregoing events or circumstances, reduces the rate of return on its capital as a consequence of its obligations under this agreement to a level below that which it otherwise could have achieved (taking into consideration its policies with respect to capital adequacy) by an amount deemed by it to be material (and it may, in determining the amount, utilize reasonable assumptions and allocations of costs and expenses and use any reasonable averaging or attribution method), then (unless the effect is already reflected in the rate of interest then applicable under this agreement) Administrative Agent or that Lender (through Administrative Agent) shall deliver to the applicable Borrower or Borrowers a certificate setting forth in reasonable detail (but the Lender shall not be obligated to disclose confidential information) the calculation of the amount necessary to compensate it (which certificate is conclusive and binding absent manifest error), and that Borrower or those Borrowers shall pay that amount to Administrative Agent or that Lender within five days after demand. The provisions of and undertakings and indemnification in this CLAUSE (b) shall survive the satisfaction and payment of the Obligation and termination of this agreement. 4.17 CHANGE IN LAWS. If any Governmental Requirement makes it unlawful for -------------- any Lender to make or maintain any Borrowings, then that Lender shall promptly notify Borrowers and Administrative Agent, and: (a) as to undisbursed funds, the requested Borrowing shall be made as another Type of Borrowing if lawful or otherwise shall not be made; (b) as to any outstanding Base-Rate Borrowing (i) if not prohibited by applicable Governmental Requirements, then that Base-Rate Borrowing shall be converted to a Euro-Rate Borrowing as of three Business Days after the date of notice, or (ii) if that conversion will not resolve the unlawfulness, then applicable Borrower or Borrowers shall promptly prepay that Base-Rate Borrowing without penalty; and (c) as to any outstanding Euro-Rate Borrowing (i) if maintaining a Euro-Rate Borrowing until the last day of the applicable Interest Period is unlawful, then that Borrowing shall be converted to a Base-Rate Borrowing as of the date of notice, or (ii) if not prohibited by applicable Governmental Requirements, that Euro-Rate Borrowing, if under the US Facility, shall be converted to a Base-Rate Borrowing as of the last day of the applicable Interest Period, or (iii) if any conversion will not resolve the unlawfulness, or in any case under the UK Facility, then the applicable Borrower or Borrowers shall promptly prepay that Euro-Rate Borrowing without penalty but with related Funding Loss. 4.18 FUNDING LOSS. US BORROWER IN RESPECT OF THE US OBLIGATION AND UK ------------ BORROWERS JOINTLY AND SEVERALLY IN RESPECT OF THE UK OBLIGATION SHALL INDEMNIFY EACH LENDER AGAINST, AND PAY TO IT UPON DEMAND, ANY FUNDING LOSS OF THAT LENDER. WHEN ANY LENDER DEMANDS THAT A BORROWER PAY ANY FUNDING LOSS, THAT LENDER SHALL DELIVER TO THAT BORROWER AND ADMINISTRATIVE AGENT A CERTIFICATE SETTING FORTH IN REASONABLE Credit Agreement ---------------- 37 DETAIL THE BASIS FOR IMPOSING FUNDING LOSS AND THE CALCULATION OF THE AMOUNT, WHICH CALCULATION IS CONCLUSIVE AND BINDING ABSENT MANIFEST ERROR. THE PROVISIONS OF AND UNDERTAKINGS AND INDEMNIFICATION IN THIS SECTION SURVIVE THE SATISFACTION AND PAYMENT OF THE US OBLIGATION AND UK OBLIGATION AND TERMINATION OF THIS AGREEMENT. 4.19 TAXES, GROSSING UP PROVISIONS, AND VALUE ADDED TAX. -------------------------------------------------- (a) US FACILITY. ----------- (i) If any Taxes shall ever become payable by Administrative Agent or any Lender or shall be ruled (by a Governmental Authority) payable by Administrative Agent or any Lender in respect of the US Facility, such Taxes shall, if lawful, be paid by (or if such Taxes have already been paid, shall be reimbursed by) US Borrower, together with interest and penalties, if any, except for Taxes payable on or measured by the overall net income of any such Lender or Administrative Agent and except for interest and penalties incurred as a result of the gross negligence or wilful misconduct of Administrative Agent or any Lender. Administrative Agent or such Lender (through Administrative Agent) shall notify US Borrower and deliver to US Borrower a certificate setting forth in reasonable detail the calculation of the amount of such Taxes, which certificate shall be conclusive and binding (absent manifest error), and US Borrower shall promptly pay such amount (including any additional Taxes applicable to the additional sums paid under this SECTION 4.19(a)(i), such that Administrative Agent or such Lender receives an amount equal to the sum it would have received had no such Taxes been payable by Administrative Agent or any Lender with respect to the US Facility) to Administrative Agent for its account or the account of such Lender, as the case may be. However, if Administrative Agent or any Lender, as the case may be, determines that it has received, realized, utilized, and retained a Tax benefit by reason of any deduction or withholding in respect of which US Borrower has made an increased payment or paid a compensating sum under this SECTION 4.19(a), then Administrative Agent or that Lender shall (if Administrative Agent or that Lender has received all amounts which are then due and payable by US Borrower under any of the provisions of this agreement or any other Loan Document) pay to US Borrower such amount, if any, as Administrative Agent or that Lender reasonably determines will leave Administrative Agent or that Lender in no worse position than it would have been in if the deduction or withholding had not been required. Nothing herein contained shall interfere with the right of Administrative Agent or any Lender, as the case may be, to arrange its Tax affairs in whatever manner it thinks fit. (ii) To the extent lawful and applicable, each Lender under the US Facility shall execute and deliver to US Borrower and Administrative Agent from time to time two duly completed copies of U.S. Internal Revenue Service Form 4224, Form 1001, Form W-8, or other appropriate Internal Revenue Service form that entitles it to a complete exemption from U.S. federal withholding Tax on all interest or fee payments in respect of the US Facility under the Loan Documents. (b) UK FACILITY. All sums payable to Administrative Agent and each ----------- Lender in respect of the UK Facility shall be paid in full without any set- off or counterclaim whatsoever and free and clear of all deductions or withholdings for or on account of any Tax whatsoever save only as may be required by law. If any deduction or withholding for or on account of any Tax is required by law in respect of any payment due to Administrative Agent or any Lender, as the case may be, pursuant to or in connection with the UK Facilities, then UK Borrowers shall jointly and severally: Credit Agreement ---------------- 38 (i) ensure or procure that the deduction or withholding is made and that it does not exceed the minimal legal requirement therefor; (ii) pay, or procure the payment of, the full amount deducted or withheld to the relevant Taxation authority in accordance with the applicable law; (iii) increase the payment in respect of which the deduction or withholding for or on account of Tax is required so that the net amount received and retained (free from any liability in respect of such deduction or withholding) by Administrative Agent or any Lender after the deduction or withholding (and after taking account of any further deduction or withholding which is required to be made as a consequence of the increase) shall be equal to the amount which Administrative Agent or that Lender would have been entitled to receive in the absence of any requirement to make a deduction or withhold; and (iv) use reasonable endeavors promptly to deliver or procure the delivery to Administrative Agent or that Lender appropriate receipts evidencing the deductions or withholding which has been made in accordance with this SECTION 4.19(b). If Administrative Agent is obliged to make any deduction or withholding from any payment to any Lender (an "AGENCY PAYMENT") which represents an amount or amounts received by the Administrative Agent from either UK Borrower pursuant to the UK Facilities, then UK Borrowers shall jointly and severally pay directly to the relevant Lender such sum (a "COMPENSATING SUM") as will, after taking into account any deduction or withholding which UK Borrowers are obliged to make from the compensating sum, enable that Lender to receive and retain (free from any liability in respect of such deduction or withholding), on the due date for payment of the agency payment, an amount equal to the agency payment which that Lender would have received in the absence of any obligation to make a deduction or withholding. However, if Administrative Agent or any Lender, as the case may be, determines that it has received, realized, utilized, and retained a Tax benefit by reason of any deduction or withholding in respect of which a UK Borrower has made an increased payment or paid a compensating sum under this SECTION 4.19(b), then Administrative Agent or that Lender shall (if Administrative Agent or that Lender has received all amounts which are then due and payable by UK Borrowers under any of the provisions of this agreement or any other Loan Document) pay to UK Borrowers such amount, if any, as Administrative Agent or that Lender reasonably determines will leave Administrative Agent or that Lender in no worse position than it would have been in if the deduction or withholding had not been required. Nothing herein contained shall interfere with the right of Administrative Agent or any Lender, as the case may be, to arrange its Tax affairs in whatever manner it thinks fit. A Borrower shall only be required to make any payment or increased payment pursuant to this SECTION 4.19(b) where it relates to a payment of interest (other than, for the avoidance of doubt, interest at the Default Rate) to the extent that the obligation to make a deduction or withholding (in respect of which such a payment or increased payment is made) arises as a result of: (A) the Lender not being a Bank as that term is defined in Section 840A of the Income and Corporation Taxes Act 1988 and at the time the interest was paid the Person beneficially entitled to the interest was within the charge to corporation Tax in the United Kingdom as respects the interest, other than where that Lender has ceased to be a Bank, as so Credit Agreement ---------------- 39 defined, or has ceased to be within the charge to corporation Tax in the United Kingdom as a consequence of a Change in Law occurring after the date of this agreement; or (B) the Lender not being resident for Tax purposes in any jurisdiction with which the United Kingdom (or any other jurisdiction where any of UK Borrowers are resident for Tax purposes) has, on the date of this agreement, a Double Tax Treaty that allows for payments of interest to be paid to that jurisdiction from the United Kingdom (or such other jurisdictions where either UK Borrowers is resident for Tax purposes) free of any deduction or withholding, other than where such Lender has ceased to so resident as a consequence of a Change in Law occurring after the date of this agreement. Each Lender will (at no additional cost to it) make and file all such Tax returns and statements as Administrative Agent or UK Borrowers may reasonably notify and request to be made or filed in connection with or for the purpose of avoiding any such deduction or withholding under this SECTION 4.19(b). Nothing herein shall interfere with the right of Administrative Agent or any Lender to arrange its Tax affairs in whatever manner it thinks fit. (c) GROSSING-UP OF INDEMNITY PAYMENTS FOR UK FACILITY. If ------------------------------------------------- Administrative Agent or any Lender under the UK Facility, as the case may be, makes a payment or suffers a loss in respect of which it is entitled to be indemnified, reimbursed, or otherwise kept harmless pursuant to any provision of this agreement and Administrative Agent or that Lender, as the case may be, considers that: (i) the Loss or payment is not or is unlikely to be wholly deductible in computing the profits of Administrative Agent or that Lender for the purposes of Tax whilst the payment to be made by way of indemnity or reimbursement (for the purpose of this SECTION 4.19(c), the "PAYMENT") will or is likely to give rise to a Tax liability for such Administrative Agent or Lender; or (ii) the payment is likely to give rise to a Tax liability for Administrative Agent or that Lender in any accounting period of Administrative Agent or that Lender earlier than the accounting period in which the Loss or payment is or is likely to be deductible; then, at the time of making the payment UK Borrowers shall jointly and severally pay such an amount (the "ADDITIONAL PAYMENT") as will, after taking into account any Tax liability likely to be suffered or incurred by Administrative Agent or that Lender in respect of the payment or additional payment, leave Administrative Agent or that Lender in the same after-Tax position as it would have been in had the payment not given rise to any such Tax liability and the loss or payment had not been so deductible. However, if: (A) at the time of the payment, Administrative Agent or that Lender considers that no additional payment is necessary but subsequently considers that an additional payment is necessary so to indemnify Administrative Agent or that Lender the additional payment shall be paid by UK Borrowers to Administrative Agent or that Lender following a demand by Administrative Agent or that Lender; or (B) if it subsequently proves that any payment by UK Borrowers to either Administrative Agent or any Lender, as the case may be, under this SECTION 4.19(c) by way of an additional payment or payment by Administrative Agent or any Lender, as the case may be, to UK Borrowers was calculated on an incorrect basis, such adjustment shall be made between Credit Agreement ---------------- 40 Administrative Agent or that Lender and UK Borrowers as Administrative Agent or that Lender considers necessary to restore the after-Tax position of Administrative Agent or that Lender to that which it would have been if no adjustment had been necessary. (d) VALUE ADDED TAX. All payments made by UK Borrowers under this --------------- agreement are calculated without regard to Value Added Tax. If any payment by either UK Borrower constitutes the whole or any part of the consideration for a taxable or deemed taxable supply (whether that supply is taxable pursuant to the exercise of an option or otherwise) by any of the Lenders, the amount of that payment shall be increased by an amount equal to the amount of Value Added Tax which is chargeable in respect of the taxable supply in question. SECTION 5 FEES. - -------------- 5.1 TREATMENT OF FEES.

UK Borrowers shall jointly and severally pay to Administrative Agent unused commitment fees, for the ratable account of the Lenders under the UK Facility in accordance with their respective Commitment Percentages of it, each installment of which is calculated for the calendar quarter (or portion of a calendar quarter commencing on the Closing Date for the UK Facility or ending on the Termination Date) preceding and including the date it is due, and is equal to the product of (i) 0.50% of the amount by which the daily average total UK-Facility Commitments exceed the sum of the daily average UK-Facility-Commitment Usage times (ii) a Credit Agreement ---------------- 41 fraction with the number of days in the applicable quarter or portion of it as the numerator and 360 as the denominator. 5.4 BG AND LC FEES. -------------- (a) As an inducement for the issuance and extension of each LC under the LC Subfacility and payable on the date of issuance or extension, US Borrower shall pay to the Issuer under the LC Subfacility, (i) a fronting fee equal to an annual percentage of 0.25% of the face amount of the LC for its tenor, for the Issuer's sole account, and (ii) an issuance or extension fee equal to an annual percentage of the face amount of the LC for its tenor, which percentage is the Applicable Margin in effect for Euro-Rate Borrowings on the date of issuance or extension, to be shared with the Lenders under the US Facility ratably in accordance with their respective Commitment Percentages under the US Facility. (b) As an inducement for the issuance and extension of each BG and LC under the BG/LC Subfacility and payable on the date of issuance or extension, UK Borrowers shall jointly and severally pay to the Issuer under the BG/LC Subfacility (i) a fronting fee equal to an annual percentage of 0.25% of the face amount of the BG or LC for its tenor, for the Issuer's sole account, and (ii) an issuance or extension fee equal to an annual percentage of the face amount of the BG or LC for its tenor, which percentage is the Applicable Margin in effect for Euro-Rate Borrowings on the date of issuance or extension, to be shared with the Lenders under the UK Facility ratably in accordance with the respective UK-Revolving- Commitment Percentages.

Credit Agreement ---------------- 59 (b) OTHER EVENTS OF DEFAULT.

If, for the purpose of obtaining judgment in any ----------------- court, it is necessary to convert an amount due under any Loan Document from a currency (the "ORIGINAL CURRENCY") into another currency (the "OTHER CURRENCY"), then the rate of exchange used shall be that at which Administrative Agent (in accordance with normal banking procedures) could purchase the Original Currency with the Other Currency at its principal office in Dallas, Texas, two Business Days before the day on which final judgment is given. (a) Any Borrower's obligation for any amount due in the Original Currency from it to either Agent or to any Lender under any Loan Document shall (notwithstanding any judgment in any Other Currency) be discharged only if and to the extent that -- on the Business Day following the day on which that Agent or that Lender receives any amount adjudged to be so due in the Other Currency -- that Agent or Lender is able (in accordance with normal banking procedures) to purchase the same amount of the Original Currency with the Other Currency as the amount that Administrative Agent could have purchased two Business Days before the day on which the final judgment referred to above is given. (b) If the amount of the Original Currency so purchased under CLAUSE (A) above by that Agent or that Lender is less than the amount of the Original Currency that Administrative Agent could have so purchased, then that Borrower shall (as a separate obligation and notwithstanding any such judgment) remit the deficiency to that Agent or that Lender.

Credit Agreement ---------------- 60 15.4 PERFORMANCE BY ADMINISTRATIVE AGENT. If any Company's covenant, duty, ----------------------------------- or agreement is not performed in accordance with the terms of the Loan Documents, Administrative Agent may, while an Event of Default exists, at its option (but subject to the approval of Required Lenders), perform or attempt to perform that covenant, duty, or agreement on behalf of that Company (and any amount expended by Administrative Agent in its performance or attempted performance is payable by the Companies, jointly and severally, to Administrative Agent on demand, becomes part of the US Obligation and the UK Obligation, and bears interest at the Default Rate from the date of Administrative Agent's expenditure until paid). However, Administrative Agent does not assume and shall never have, except by its express written consent, any liability or responsibility for the performance of any Company's covenants, duties, or agreements. 15.5 NOT IN CONTROL. Nothing in any Loan Documents gives or may be deemed -------------- to give to either Agent or any Lender the Right to exercise control over any Company's Real Property, other assets, affairs, or management or to preclude or interfere with any Company's compliance with any Governmental Requirement or require any act or omission by any Company that may be harmful to Persons or property. Any "Material-Adverse Event" or other materiality or substantiality qualifier of any representation, warranty, covenant, agreement, or other provision of any Loan Document is included for credit documentation purposes only and does not imply or be deemed to mean that either Agent or any Lender acquiesces in any non-compliance by any Company with any Governmental Requirement, document, or otherwise or does not expect the Companies to promptly, diligently, and continuously carry out all appropriate removal, remediation, compliance, closure, or other activities required or appropriate in accordance with all Environmental Laws. Agents' and Lenders' power is limited to the Rights provided in the Loan Documents. All of those Rights exist solely (and may be exercised in manner calculated by Agents or Lenders in their respective good faith business judgment) to preserve and protect the Collateral and to assure payment and performance of the US Obligation and the UK Obligation. 15.6 COURSE OF DEALING. The acceptance by Agents or Lenders of any partial ----------------- payment on the US Obligation or the UK Obligation is not a waiver of any Event of Default then existing. No waiver by either Agent, Required Lenders, or Lenders of any Event of Default is a waiver of any other then-existing or subsequent Event of Default. No delay or omission by either Agent, Required Lenders, or Lenders in exercising any Right under the Loan Documents impairs that Right or is a waiver thereof or any acquiescence therein, nor will any single or partial exercise of any Right preclude other or further exercise thereof or the exercise of any other Right under the Loan Documents or otherwise. 15.7 CUMULATIVE RIGHTS. All Rights available to Agents, Required Lenders, ----------------- and Lenders under the Loan Documents are cumulative of and in addition to all other Rights granted to Agents, Required Lenders, and Lenders at law or in equity, whether or not the US Obligation or the UK Obligation are due and payable and whether or not Agents, Required Lenders, or Lenders have instituted any suit for collection, foreclosure, or other action in connection with the Loan Documents. 15.8 APPLICATION OF PROCEEDS. Any and all proceeds ever received by Agents ----------------------- or Lenders from the exercise of any Rights pertaining to the US Obligation or the UK Obligation shall be applied to the US Obligation or the UK Obligation according to SECTION 4. 15.9 CERTAIN PROCEEDINGS.

Because Borrowers agree that Credit Agreement ---------------- 61 Administrative Agent's and Required Lenders' remedies at law for failure of Borrowers to comply with the provisions of this section would be inadequate and that failure would not be adequately compensable in damages, Borrowers agree that the covenants of this section may be specifically enforced. 15.10 EXPENDITURES BY LENDERS. Any sums spent by either Agent or any Lender ----------------------- in the exercise of any Right under any Loan Document is payable by the Companies to Administrative Agent within five Business Days after demand, becomes part of the US Obligation and the UK Obligation, and bears interest at the Default Rate from the date spent until the date repaid. 15.11 DIMINUTION IN VALUE OF COLLATERAL. Neither Agent nor any Lender has --------------------------------- any liability or responsibility whatsoever for any diminution in or loss of value of any collateral now or in the future securing payment or performance of any of the US Obligation or the UK Obligation (other than diminution in or loss of value caused by its own gross negligence or willful misconduct). 15.12 UK BORROWERS' OBLIGATIONS. Nothing in this SECTION 15 shall be ------------------------- construed to make the UK Borrowers obligated in any way with respect to any of the US Obligation or its enforcement. SECTION 16 AGENTS AND LENDERS. - ---------- ------------------ 16.1 AGENTS. ------ (a) ADMINISTRATIVE AGENT. Except as provided in CLAUSE (B) below, -------------------- each Lender appoints Administrative Agent (including, without limitation, each successor Administrative Agent in accordance with this SECTION 16) as its nominee and agent to act in its name and on its behalf (and Administrative Agent and each such successor accepts that appointment): (i) To act as its nominee and on its behalf in and under all Loan Documents; (ii) to arrange the means whereby Borrowings are to be made available to Borrowers (except under the Overdraft Subfacility) under the Loan Documents; (iii) to take any action that it properly requests under the Loan Documents (subject to the concurrence of other Lenders as may be required under the Loan Documents); (iv) to receive all documents and items to be furnished to it under the Loan Documents; (v) to be the secured party, mortgagee, beneficiary, recipient, and similar party in respect of any collateral for the benefit of Lenders except when the UK-Collateral Agent is serving in that function; (vi) to promptly distribute to it all material information, requests, documents, and items received from any Borrower under the Loan Documents; (vii) to promptly distribute to it its ratable part of each payment or prepayment (whether voluntary, as proceeds of collateral upon or after foreclosure, as proceeds of insurance thereon, or otherwise) in accordance with the terms of the Loan Documents; and (viii) to deliver to the appropriate Persons requests, demands, approvals, and consents received from it. However, Administrative Agent may not be required to take any action that exposes it to personal liability or that is contrary to any Loan Document or applicable Governmental Requirements. (b) UK-COLLATERAL AGENT. Each Lender under the UK Facility appoints ------------------- that UK-Collateral Agent (including, without limitation, each successor UK- Collateral Agent in accordance with this SECTION 16) as its nominee and agent to act in its name and on its behalf (and that UK-Collateral Agent and each such successor accepts that appointment): (i) To be the secured party, mortgagee, beneficiary, recipient, and similar party in respect of any collateral as may be appropriate in connection with the UK Facility for the benefit of the Lenders under the UK Facility; (ii) to take any action that it properly requests under the Loan Documents (subject to the concurrence of other Lenders under the UK Facility as may be required under the Loan Documents); (iii) to promptly distribute to it all material information, requests, documents, and Credit Agreement ---------------- 62 items received from any Borrower under the Loan Documents; (iv) to promptly distribute to it its ratable part of each payment or prepayment (whether voluntary, as proceeds of collateral upon or after foreclosure, as proceeds of insurance thereon, or otherwise) in accordance with the terms of the Loan Documents; and (v) to deliver to the appropriate Persons requests, demands, approvals, and consents received from it. However, UK-Collateral Agent may not be required to take any action that exposes it to personal liability or that is contrary to any Loan Document or applicable Governmental Requirements. (c) SUCCESSOR. Either Agent may assign all of its Rights and --------- obligations as an Agent under the Loan Documents to any of its Affiliates, which Affiliate shall then be the successor to that Agent under the Loan Documents. Either Agent may also voluntarily resign and shall resign upon the request of Required Lenders for cause (i.e., its continuing to fail to perform its responsibilities as an Agent under the Loan Documents). If any such successor ever ceases to be a party to this agreement or if the initial or any such successor ever resigns (whether voluntarily or at the request of Required Lenders), then Required Lenders shall appoint the successor from among Lenders (other than the resigning Agent). If Required Lenders fail to appoint a successor within 30 days after the resigning Agent has given notice of resignation or Required Lenders have removed the resigning Agent, then the resigning Agent may, on behalf of Lenders, appoint a successor, which must be a commercial bank having a combined capital and surplus of at least the Dollar Equivalent of $1,000,000,000 (as shown on its most recently published statement of condition). Upon its acceptance of appointment as successor, the successor succeeds to and becomes vested with all of the Rights of the former Agent, and the former Agent is discharged from its duties and obligations as an Agent under the Loan Documents, and each Lender shall execute the documents that any Lender, the resigning or removed Agent, or the successor Agent reasonably request to reflect the change. After any Agent's resignation or removal as an Agent under the Loan Documents, the provisions of this section inure to its benefit as to any actions taken or not taken by it while it was an Agent under the Loan Documents. (d) RIGHTS AS LENDER. Each Agent, in its capacity as a Lender, has ---------------- the same Rights under the Loan Documents as any other Lender and may exercise those Rights as if it were not acting as an Agent. The term "Lender", unless the context otherwise indicates, includes each Agent. An Agent's resignation or removal does not impair or otherwise affect any Rights that it has or may have in its capacity as an individual Lender. Each Lender and each Borrower agree that neither Agent is a fiduciary for Lenders or Borrowers but is simply acting in the capacity described in this agreement to alleviate administrative burdens for Borrowers and Lenders, that neither Agent has any duties or responsibilities to Lenders or Borrowers except those expressly set forth in the Loan Documents, and that each Agent in its capacity as a Lender has the same Rights as any other Lender. (e) OTHER ACTIVITIES. Subject to SECTIONS 10.2, 11.2, and 12.2, each ---------------- Agent or any Lender may now or in the future be engaged in one or more loan, letter of credit, leasing, or other financing transactions with any Borrower, act as trustee or depositary for any Borrower, or otherwise be engaged in other transactions with any Borrower (collectively, the "OTHER ACTIVITIES") not the subject of the Loan Documents. Without limiting the Rights of Lenders specifically set forth in the Loan Documents, neither Agent nor any Lender is responsible to account to the other Agent or Lenders for those other activities, and no Lender shall have any interest in any other Lender's activities, any present or future guaranties by or for the account of any Borrower that are not contemplated by or included in the Loan Documents, any present or future offset exercised by either Agent or any Lender in respect of those other activities, any present or future property taken as security for any of those other activities, or any property now or hereafter in either Credit Agreement ---------------- 63 Agent's or any Lender's possession or control that may be or become security for the obligations of any Borrower arising under the Loan Documents by reason of the general description of indebtedness secured or of property contained in any other agreements, documents, or instruments related to any of those other activities (but, if any payments in respect of those guaranties or that property or the proceeds thereof is applied by that Agent or Lender to reduce the US Obligation or the UK Obligation, then each Lender is entitled to share ratably in the application to the extent so provided in the Loan Documents). 16.2 EXPENSES.

Each Lender is entitled to receive, according to its Commitment Percentage of the US Facility and the UK Facility combined, part of any reimbursement that it makes to either Agent or Issuer if they are subsequently reimbursed from other sources. 16.3 PROPORTIONATE ABSORPTION OF LOSSES. Except as otherwise provided in ---------------------------------- the Loan Documents nothing in the Loan Documents (a) gives any Lender under the US Facility any advantage over any other Lender under the US Facility insofar as the US Obligation is concerned or relieves any such Lender from ratably absorbing any losses sustained with respect to the US Obligation (except to the extent unilateral actions or inactions by any Lender result in US Borrower or any other obligor on the US Obligation having any credit, allowance, set off, defense, or counterclaim solely with respect to all or any part of that Lender's part of the US Obligation), determined according to that Lender's Commitment Percentage of the US Facility, or (b) gives any Lender under the UK Facility any advantage over any other Lender under the UK Facility insofar as the UK Obligation is concerned or relieves any such Lender from ratably absorbing any losses sustained with respect to the UK Obligation (except to the extent unilateral actions or inactions by any Lender result in UK Borrowers or any other obligor on the UK Obligation having any credit, allowance, set off, defense, or counterclaim solely with respect to all or any part of that Lender's part of the UK Obligation), determined according to that Lender's Commitment Percentage of the UK Facility. 16.4 DELEGATION OF DUTIES; RELIANCE. Lenders may perform any of their ------------------------------ duties or exercise any of their Rights under the Loan Documents by or through the appropriate Agent, and Lenders and Agents may perform any of their duties or exercise any of their Rights under the Loan Documents by or through their respective Affiliates and Representatives. Each Agent and each Lender (and each of their respective Representatives) (a) is entitled to rely upon (and shall be protected in relying upon) any written or oral statement believed by it or them to be genuine and correct and to have been signed or made by the proper Person and, with respect to legal matters, upon opinion of counsel it has selected, (b) is entitled to deem and treat each Lender as the owner and holder of its portion of the US Obligation or the UK Obligation, as the case may be, for all purposes until, written notice of the assignment or transfer is given to and received by it (and any request, authorization, consent, or approval of any Lender is conclusive and binding on each subsequent holder, assignee, or transferee of or Participant in that Lender's portion of the US Obligation or the UK Obligation, as the case may be, until that notice is given and received), (c) is not deemed to have notice of the occurrence of an Event of Default unless a responsible officer of that Agent or that Lender, as the case may be, who handles matters associated with the Loan Documents and transactions thereunder, has actual knowledge or has been notified by either Agent, a Lender, or a Borrower, and (d) is entitled to consult with legal counsel (including counsel for any Borrower), independent accountants, and other experts it has selected and is not liable for any action taken or not taken in good faith by it in accordance with the advice of counsel, accountants, or experts.

(b) INDEMNITY. Unless indemnified to its satisfaction against loss, --------- cost, liability, and expense, neither Agent may 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 an Agent requests instructions from Lenders, or Required Lenders, as the case may be, with respect to any act or action in connection with any Loan Document, that Agent is entitled to refrain (without incurring any liability to any Person by so refraining) from that act or action unless and until it has received instructions. In no event, however, may an Agent or any of its Representatives be required to take any action that it or they determine could incur for it or them criminal or onerous civil liability. Without limiting the generality of the foregoing, no Lender has any right of action against either Agent as a result of an Agent's acting or refraining from acting under this agreement in accordance with instructions of Required Lenders. (c) RELIANCE. Neither Agent is responsible to any Lender or any -------- Participant for, and each Lender represents and warrants that it has not relied upon either Agent in respect of, (i) the creditworthiness of any Company and the risks involved to that Lender, (ii) the effectiveness, enforceability, genuineness, validity, or the due execution of any Loan Document, (iii) any representation, warranty, document, certificate, report, or statement made therein or furnished thereunder or in connection therewith, (iv) the adequacy of any collateral now or hereafter securing the Obligation or the existence, priority, or perfection of any Lien now or hereafter granted or purported to be granted on the collateral under any Loan Document, or (v) observation of or compliance with any of the terms, covenants, or conditions of any Loan Document on the part of any Company. EACH LENDER AGREES TO INDEMNIFY EACH AGENT AND ITS REPRESENTATIVES AND HOLD THEM HARMLESS FROM AND AGAINST (BUT LIMITED TO SUCH LENDER'S COMMITMENT PERCENTAGE OF THE US FACILITY AND THE UK FACILITY COMBINED) ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, REASONABLE EXPENSES, AND REASONABLE DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER THAT MAY BE IMPOSED ON, ASSERTED AGAINST, OR INCURRED BY THEM IN ANY WAY RELATING TO OR ARISING OUT OF THE LOAN DOCUMENTS OR ANY ACTION TAKEN OR OMITTED BY THEM UNDER THE LOAN DOCUMENTS IF AGENT AND ITS REPRESENTATIVES ARE NOT REIMBURSED FOR SUCH AMOUNTS BY ANY COMPANY. ALTHOUGH EACH AGENT AND ITS REPRESENTATIVES HAVE THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR THEIR OWN ORDINARY NEGLIGENCE, NEITHER AGENT NOR ITS REPRESENTATIVES DO NOT HAVE THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR THEIR OWN FRAUD, GROSS NEGLIGENCE, OR WILLFUL MISCONDUCT. Only as between Lenders (and not Borrowers or any other Persons), their respective US-Facility Commitments and UK-Facility Commitments are, for purposes of the calculations and determinations required to be made under his agreement and in particular for he purposes of the indemnity under this CLAUSE (C), deemed to have survived any termination or cancellation under Section 15. Credit Agreement ---------------- 65 16.6 EVENT OF DEFAULT. While an Event of Default exists, 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. Each Agent is entitled to act or refrain from taking any action (without incurring any liability to any Person for so acting or refraining) unless and until it has received instructions from Required Lenders. In actions with respect to any Company's property, each Agent is acting for the ratable benefit of each Lender. 16.7 COLLATERAL MATTERS. ------------------ (a) Each Lender authorizes and directs each Agent to enter into the Loan Documents for the Lender Liens and agrees that any action taken by an Agent concerning any collateral (with the consent or at the request of Required Lenders) in accordance with any Loan Document, that Agent's exercise (with the consent or at the request of Required Lenders) of powers concerning the collateral in any Loan Document, and that all other reasonably incidental powers are authorized and binding upon all Lenders. (b) Each Agent is authorized on behalf of all Lenders, without the necessity of any notice to or further consent from any Lender, from time to time before an Event of Default or Potential Default, to take any action with respect to any collateral or Loan Documents related to collateral that may be necessary to perfect and maintain perfected the Lender Liens upon the collateral. (c) Except to use the same standard of care that it ordinarily uses for collateral for its sole benefit, neither Agent has any obligation whatsoever to any Lender or to any other Person to assure that the Collateral exists or is owned by any Company or is cared for, protected, or insured or has been encumbered or that the Lender Liens have been properly or sufficiently or lawfully created, perfected, protected, or enforced or are entitled to any particular priority. (d) Each Agent shall exercise the same care and prudent judgment with respect to the collateral and the Loan Documents as it normally and customarily exercises in respect of similar collateral and security documents. (e) Lenders irrevocably authorize each Agent, at its option and in its discretion, to release any Lender Lien upon any collateral (i) in accordance with SECTION 6.5, (ii) constituting property being disposed of as permitted under any Loan Document, (iii) constituting property in which no Company owned any interest at the time the Lender Lien was granted or at any time after that, (iv) constituting property leased to any Company under a lease that has expired or been terminated in a transaction permitted under the Loan Documents or is about to expire and that has not been, and is not intended by that Company to be, renewed, (v) consisting of an instrument evidencing Debt pledged to that Agent (for the benefit of Lenders), if the underlying Debt has been paid in full, or (vi) if approved, authorized, or ratified in writing by Lenders. Upon request by either Agent at any time, Lenders shall confirm in writing Administrative Agent's authority to release particular types or items of collateral under this CLAUSE (E). 16.8 LIMITATION OF LIABILITY. No Lender or any Participant will incur any ----------------------- liability to any other Lender or Participant except for acts or omissions in bad faith, and neither of the Agents nor any Lender or Participant will incur any liability to any other Person for any act or omission of any other Lender or any Participant. Credit Agreement ---------------- 66 16.9 RELATIONSHIP OF LENDERS. The Loan Documents do not create a ----------------------- partnership or joint venture between Agents and Lenders or any of them. 16.10 BENEFITS OF AGREEMENT. None of the provisions of this section inure --------------------- to the benefit of any Company or any other Person except Agents and Lenders. Therefore, no Company or any other Person is responsible or liable for, entitled to rely upon, or entitled to raise as a defense -- in any manner whatsoever -- the failure of Agents or any Lender to comply with these provisions. SECTION 17 MISCELLANEOUS. - ------------------------ 17.1 NONBUSINESS DAYS. Any payment or action that is due under any Loan ---------------- Document on a non-Business Day may be delayed until the next-succeeding Business Day (but interest shall continue to accrue on any applicable payment until payment is in fact made) unless the payment concerns a Euro-Rate Borrowing, in which case if the next-succeeding Business Day is in the next calendar month, then such payment shall be made on the next-preceding Business Day. 17.2 COMMUNICATIONS. Unless otherwise specifically provided, whenever any -------------- Loan Document requires or permits any consent, approval, notice, request, or demand from one party to another, com munication must be in writing (which may be by telex or fax) to be effective and shall be deemed to have been given (a) if by telex, when transmitted to the appropriate telex number and the appropriate answer back is received, (b) if by fax, when transmitted to the appropriate fax number (and all communications sent by fax must be confirmed promptly thereafter by telephone; but any requirement in this parenthetical shall not affect the date when the fax shall be deemed to have been delivered), (c) if by mail, on the fifth Business Day after it is enclosed in an envelope and properly addressed, stamped, sealed, and deposited in the appropriate official postal service, or (d) if by any other means, when actually delivered.

All covenants, agreements, undertakings, representations, -------- and warranties made in any of the Loan Documents survive all closings under the Loan Documents and, except as otherwise indicated, are not affected by any investigation made by any party. 17.6 GOVERNING LAW. Unless otherwise stated in any Loan Document, the laws ------------- of the State of Texas and of the United States of America govern the Rights and duties of the parties to the Loan Documents and the validity, construction, enforcement, and interpretation of the Loan Documents. 17.7 INVALID PROVISIONS. Any provision in any Loan Document held to be ------------------ illegal, invalid, or unenforceable is fully severable; the appropriate Loan Document shall be construed and enforced as if that provision had never been included; and the remaining provisions shall remain in full force and effect and shall not be affected by the severed provision. Agents, Lenders, and each Company party to the affected Credit Agreement ---------------- 67 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. 17.8 CERTAIN REINSTATEMENT. If any payment or prepayment under any Loan --------------------- Document is ever rescinded or must be restored or returned for any reason, then all Rights and obligations under the Loan Documents in respect of that payment or prepayment are automatically reinstated as though the payment or prepayment had not been made when due. 17.9 AMENDMENTS, WAIVERS, CONSENTS, SUPPLEMENTS, AND CONFLICTS. --------------------------------------------------------- (a) REQUIRED LENDERS. Unless otherwise specifically provided (i) the ---------------- provisions of this agreement may be amended and waivers and consents under it may be given in writing executed by those Borrowers that are then party to this agreement, Administrative Agent, and Required Lenders and supplemented only by documents delivered or to be delivered in accordance with the express terms of this agreement, and (ii) the other Loan Documents may only be amended or waived and consents under them may be given if in writing executed by the parties to that Loan Document that is also executed or approved by Required Lenders. (b) AGENTS, ISSUERS, AND OVERDRAFT LENDER. Any amendment, waiver, or ------------------------------------- consent that increases either Agent's, either Issuer's, or Overdraft Lender's obligations beyond its commitments under any Loan Document or increases, reduces, or waives the late payment or non-payment of any fees payable solely to it under SECTION 5.4 or 5.5 must be in writing executed by it, Administrative Agent, and US Borrower in respect of the US Facility or UK Borrowers in respect of the UK Facility. (c) BGS AND LCS. Any LC may be renewed, extended, amended, replaced, ----------- or canceled consistent with the terms of this agreement by writing executed by the Issuer and the obligated Borrower if that writing is first approved in writing by Administrative Agent.

(e) WAIVERS.

A waiver must be in writing and signed by the parties otherwise indicated in this SECTION 17.9 to be effective and will be effective only in the specific instance and for the specific purpose for which it is given. (f) CONFLICTS. Any conflict or ambiguity between the terms and --------- provisions of this agreement and terms and provisions in any other Loan Document is controlled by the terms and provisions of this agreement. 17.10 MULTIPLE COUNTERPARTS. Any Loan Document may be executed in a number --------------------- of identical counterparts (including, at Administrative Agent's discretion, counterparts or signature pages executed and transmitted by fax) with the same effect as if all signatories had signed the same document. All counterparts must be construed together to constitute one and the same instrument. 17.11 PARTIES. ------- (a) PARTIES BOUND. Each Loan Document binds and inures to the ------------- parties to it, any intended beneficiary of it, and each of their respective successors and permitted assigns. No Company may assign or transfer any Rights or obligations under any Loan Document without first obtaining all Lenders' consent, and any purported assignment or transfer without Lenders' consent is void. No Lender may transfer, pledge, assign, sell any participation in, or otherwise encumber its portion of the US Obligation or the UK Obligation except as permitted by CLAUSES (b) or (c) below. (b) PARTICIPATIONS. Any Lender may (subject to the provisions of -------------- this section, in accordance with applicable Governmental Requirement, in the ordinary course of its business, and at any time) sell to one or more Persons (each a "PARTICIPANT") participating interests in its portion of the US Obligation or the UK Obligation. The selling Lender remains a "Lender" under the Loan Documents, the Participant does not become a "Lender" under the Loan Documents, and the selling Lender's obligations under the Loan Documents remain unchanged. The selling Lender remains solely responsible for the performance of its obligations and remains the holder of its share of the Principal Debt for all purposes under the Loan Documents. Borrowers and Agents shall continue to deal solely and directly with the selling Lender in connection with that Lender's Rights and obligations under the Loan Documents, and each Lender must retain the sole right and responsibility to enforce due obligations of the Companies. Participants have no Rights under the Loan Documents except as provided below. Subject to the following, each Lender may obtain (on behalf of its Participants) the benefits of SECTION 4 with respect to all participations in its part of the US Obligation or the UK Obligation outstanding from time to time so long as no Borrower is obligated to pay any amount in excess of the amount that would be due to that Lender under SECTION 4 calculated as though no participations have been made. No Lender may sell any participating interest under which the Participant has any Rights to approve any amendment, modification, or waiver of any Loan Document except as to matters in SECTION 17.9(D)(i) and (ii). (c) ASSIGNMENTS. Each Lender may make assignments to the Federal ----------- Reserve Bank. Each Lender may also assign to one or more assignees (each an "ASSIGNEE") all or any part of its Rights and obligations under the Loan Documents so long as (i) the assignor Lender and Assignee execute and deliver to Administrative Agent and US Borrower in respect of the US Obligation or UK Borrowers in respect of the UK Obligation for their consent and acceptance (that may not be unreasonably withheld in any instance and is not required if the Assignee is an Affiliate of the assigning Lender) an assignment and assumption agreement in substantially the form of EXHIBIT F (an "ASSIGNMENT") and pay to Administrative Agent a processing fee of $3,500, (ii) the Credit Agreement ---------------- 69 assignment must be for a minimum total amount of the Dollar Equivalent of $5,000,000 (or less amount if acceptable to Administrative Agent) and, if the assigning Lender retains any commitment in the facility in which the Assignment was made, it must be a minimum commitment of the Dollar Equivalent of $5,000,000 (or less amount if acceptable to Administrative Agent), and (iii) the conditions for that assignment set forth in the applicable Assignment are satisfied. The Effective Date in each Assignment must (unless a shorter period is agreeable to US Borrower in respect of the US Obligation or UK Borrowers in respect of the UK Obligation and Administrative Agent) be at least five Business Days after it is executed and delivered by the assignor Lender and the Assignee to Administrative Agent and US Borrower in respect of the US Obligation or UK Borrowers in respect of the UK Obligation for acceptance. Once that Assignment is accepted by Administrative Agent and US Borrower in respect of the US Obligation or UK Borrowers in respect of the UK Obligation, and subject to all of the following occurring, then, on and after the Effective Date stated in it (i) the Assignee automatically becomes a party to this agreement and, to the extent provided in that Assignment, has the Rights and obligations of a Lender under the Loan Documents, (ii) the assignor Lender, to the extent provided in that Assignment, is released from its obligations to fund Borrowings under this agreement for the facility the subject of the assignment and its reimbursement obligations under this agreement for that facility and, in the case of an Assignment covering all of the remaining portion of the assignor Lender's Rights and obligations under the Loan Documents, that Lender ceases to be a party to the Loan Documents, (iii) the appropriate Borrower shall execute and deliver to the assignor Lender and the Assignee the appropriate Notes in accordance with this agreement following the transfer, (iv) upon delivery of the Notes under CLAUSE (III) preceding, the assignor Lender shall return to the appropriate Borrower all Notes previously delivered to that Lender under this agreement for that facility, and (v) SCHEDULE 1 is automatically deemed to be amended to reflect the name, address, telecopy number, UK- Facility Commitment, and US-Facility Commitment of the Assignee and the remaining UK-Facility Commitment and US-Facility Commitment (if any) of the assignor Lender, and Administrative Agent shall prepare and circulate to Borrowers and Lenders an amended SCHEDULE 1 reflecting those changes. Notwithstanding the foregoing, no Assignee may be recognized as a party to the Loan Documents (and the assigning Lender shall continue to be treated for all purposes as the party to the Loan Documents) with respect to the Rights and obligations assigned to that Assignee until the actions described in CLAUSES (III) and (IV) have occurred. The US Obligation is registered on the books of US Borrower as to both principal and any stated interest, and transfers of (as opposed to participations in) principal and interest of the US Obligation may only be made in accordance with this SECTION 17.11. The UK Obligation is registered on the books of UK Borrowers as to both principal and any stated interest, and transfers of (as opposed to participations in) principal and interest of the UK Obligation may only be made in accordance with this SECTION 17.11. 17.12 VENUE, SERVICE OF PROCESS, AND JURY TRIAL. BORROWERS, IN EACH CASE ----------------------------------------- FOR THEMSELVES AND THEIR RESPECTIVE SUCCESSORS AND ASSIGNS, IRREVOCABLY (A) SUBMIT TO THE NONEXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS IN TEXAS, (B) WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE GOVERNMENTAL REQUIREMENTS, ANY OBJECTION THAT IT MAY NOW OR IN THE FUTURE HAVE TO THE LAYING OF VENUE OF ANY LITIGATION ARISING OUT OF OR IN CONNECTION WITH ANY LOAN DOCUMENT AND THE US OBLIGATION OR THE UK OBLIGATION BROUGHT IN THE DISTRICT COURTS OF DALLAS COUNTY, TEXAS, OR IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF TEXAS, DALLAS DIVISION, (C) WAIVE ANY CLAIMS THAT ANY LITIGATION BROUGHT IN ANY OF THE FOREGOING COURTS HAS BEEN BROUGHT IN AN INCONVENIENT FORUM, (D) CONSENT TO THE SERVICE OF PROCESS OF ANY OF THOSE COURTS IN ANY LITIGATION BY THE MAILING OF COPIES OF THAT PROCESS BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED, POSTAGE PREPAID, BY HAND DELIVERY, OR BY DELIVERY BY A NATIONALLY-RECOGNIZED COURIER SERVICE, AND Credit Agreement ---------------- 70 SERVICE SHALL BE DEEMED COMPLETE UPON DELIVERY OF THE LEGAL PROCESS AT ITS ADDRESS FOR PURPOSES OF THIS AGREEMENT, (E) AGREE THAT ANY LEGAL PROCEEDING AGAINST ANY PARTY TO ANY LOAN DOCUMENT ARISING OUT OF OR IN CONNECTION WITH THE LOAN DOCUMENTS OR THE US OBLIGATION OR THE UK OBLIGATION MAY BE BROUGHT IN ONE OF THE FOREGOING COURTS, AND (F) WAIVE TO THE FULLEST EXTENT PERMITTED BY APPLICABLE GOVERNMENTAL REQUIREMENTS, ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY LOAN DOCUMENT. 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. BORROWERS ACKNOWLEDGE THAT THESE WAIVERS ARE A MATERIAL INDUCEMENT TO ADMINISTRATIVE AGENT'S AND EACH LENDER'S AGREEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT ADMINISTRATIVE AGENT AND EACH LENDER HAS ALREADY RELIED ON THESE WAIVERS IN ENTERING INTO THIS AGREEMENT, AND THAT ADMINISTRATIVE AGENT AND EACH LENDER WILL CONTINUE TO RELY ON EACH OF THESE WAIVERS IN RELATED FUTURE DEALINGS. BORROWERS FURTHER WARRANT AND REPRESENT THAT THEY HAVE REVIEWED THESE WAIVERS WITH THEIR LEGAL COUNSEL, AND THAT THEY KNOWINGLY AND VOLUNTARILY AGREE TO EACH WAIVER FOLLOWING CONSULTATION WITH LEGAL COUNSEL. The waivers in this section are irrevocable, meaning that they may not be modified either orally or in writing, and these waivers apply to any future renewals, extensions, amendments, modifications, or replacements in respect of the applicable Loan Document. In connection with any Litigation, this agreement may be filed as a written consent to a trial by the court. 17.13 INFORMATION REGARDING BORROWERS. Borrowers hereby acknowledge and ------------------------------- agree that Lenders may discuss the financial condition and other information regarding any Borrowers' business affairs with each other, any Assignee, any Participant, or any prospective Assignee or Participant. 17.14 ENTIRETY. THE LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN -------- BORROWERS, LENDERS, AND ADMINISTRATIVE AGENT AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

Plasma & Materials Technologies, Inc., Electrotech Limited, Electrotech Equipments Limited, Lenders, Lloyds Bank Plc, as "UK-Collateral Agent" for the Lenders, and Secured Party have executed the Credit Agreement (as renewed, extended, amended, or restated, the "CREDIT AGREEMENT") dated as of November 15, 1996, and certain other Loan Documents. The execution and delivery of this agreement is a requirement to Secured Party's and Lenders' execution of the Credit Agreement and other Loan Documents, is integral to the transactions contemplated by the Loan Documents, and is a condition precedent to Lenders' obligations to extend credit under the Credit Agreement. ACCORDINGLY, for adequate and sufficient consideration, Debtor agrees with Secured Party for the benefit of Lenders as follows: 1. DEFINITIONS. Terms defined in the Credit Agreement or the UCC have ----------- the same meanings when used -- unless otherwise defined --in this agreement. If the definition given a term in the Credit Agreement conflicts with the definition given that term in the UCC, then the Credit Agreement definition controls to the extent lawful. If the definition given a term in Chapter 9 of the UCC conflicts with the definition given that term in any other chapter of the UCC, then the Chapter 9 definition controls. Furthermore, as used in this agreement: "ACCOUNTS" means all of Debtor's accounts, instruments, receivables, accounts receivable, chattel paper, documents, and book debts arising from its sale or lease of goods or rendition of services, including, without limitation, all (a) amounts due to it from a factor, (b) returned, reclaimed, refused, or repossessed goods, and (c) books and records pertaining to, and security and guaranties for, any of the foregoing.

"FINANCING STATEMENT" means a financing statement executed by Debtor and Secured Party for filing in the jurisdictions listed in SCHEDULE 7.1 to the Credit Agreement, and in substantially the form of EXHIBIT C-3 to the Credit Agreement. "GENERAL INTANGIBLES" means any "general intangibles," as that term is defined in Chapter 9 of the UCC, and, in any event, includes, without limitation, each of the following: (a) All of Debtor's patents, patent applications, patent rights, service marks, trademarks, trade names, trade secrets, intellectual property, registrations, goodwill, copyrights, franchises, licenses, permits, proprietary information, customer lists, designs, and inventions; (b) all of Debtor's books, records, data, plans, manuals, computer software, and computer programs; (c) all of Debtor's contract rights, partnership interests and joint venture interests (but only to the extent not otherwise pledged to the Administrative Agent pursuant to a separate pledge or security agreement), deposit accounts, investment accounts, and certificates of deposit; (d) all rights of Debtor to payment under letters of credit and similar agreements; (e) all tax refunds and tax refund claims of Debtor; (f) all choices in action and causes of action of Debtor (whether arising in contract, tort, or otherwise and whether or not currently in litigation) and all judgments in favor of Debtor; (g) all rights and claims of Debtor under warranties and indemnities; and (h) all rights of Debtor under any insurance, surety, or similar contract or arrangement. "INSTRUMENT" means any "instrument," as that term is defined in Chapter 9 of the UCC. "INVENTORY" means all of Debtor's inventory, including, without limitation, all present and future (a) materials, goods and work-in-process, finished goods, and other tangible property held for sale or lease or being processed for sale or lease in its present or future business, whether to be furnished under contracts or used or consumed in Debtor's business, (b) documents (including documents of title) covering any of the foregoing, and (c) such property the sale or other disposition of which has given rise to accounts and which has not been returned to or repossessed or stopped in transit by Debtor. "INVESTMENT PROPERTY" means "investment property," as that term is defined in Section 9.115(a)(6) of the UCC. "OBLIGOR" means any Person obligated with respect to any of the Collateral, whether as a party to a contract, an account debtor, issuer of any securities, or otherwise. "PLEDGED SECURITIES" means 100% of all capital stock now or in the future issued by each present and future Domestic Subsidiary of Debtor and 65% of all present and future capital stock now or in the future issued by each present and future Foreign Company that is a direct Subsidiary of any Debtor. "SECURED OBLIGATION" means the "US Obligation," the "UK Obligation" (as each is defined in the Credit Agreement), and Debtor's guarantee of the UK Obligation, including, without limitation, all present and future indebtedness, liabilities, and obligations of Debtor arising under this agreement, and all present and future costs, attorneys' fees, and expenses reasonably incurred by Secured Party or any Lender to enforce Debtor's or any other obligor's payment of any of the US Obligation or the UK Obligation, including, without limitation (to the extent lawful), all present and future amounts that would become due but for the operation of (S)(S) 502 or 506 or any other provision of Title 11 of the United States Code and all present and future accrued and unpaid interest (including, without limitation, all post-petition interest if Debtor voluntarily or involuntarily becomes subject to Debtor Law). "SECURED PARTY" is defined in the preamble to this agreement and includes its successor appointed under SECTION 16 of the Credit Agreement and acting as Administrative Agent for Lenders under the Loan Documents. 2 "SECURITY INTEREST" means the security interests granted and the transfers, pledges, and assignments made under PARAGRAPH 2 below, which is a "Lender Lien," as defined in the Credit Agreement. "UCC" means the Uniform Commercial Code as adopted in Texas or any other applicable jurisdiction. 2. SECURITY INTEREST. To secure the prompt, unconditional, and complete ----------------- payment and performance of the Secured Obligation when due, Debtor grants to Secured Party a security interest in the Collateral pledges and collaterally transfers and assigns that Collateral to Secured Party, all upon and subject to the terms and conditions of this agreement. If the grant, pledge, or collateral transfer or assignment of any specific item of the Collateral is expressly prohibited by any contract, then the Security Interest nonetheless remains effective to the extent allowed by UCC (S) 9.318 or other applicable Governmental Requirements but is otherwise limited by that prohibition. 3. NO ASSUMPTION OR MODIFICATION. The Security Interest is given as ----------------------------- security only in order to secure the prompt, unconditional, and complete payment and performance of the Secured Obligation when due. Neither Secured Party nor any Lender assumes or may become liable for Debtor's liabilities, duties, or obligations under or in connection with the Collateral. Neither Secured Party's acceptance of this agreement nor its taking any action in carrying out this agreement, constitutes Secured Party's approval of the Collateral or Secured Party's assumption of any obligation under or in connection with the Collateral. This agreement does not affect or modify Debtor's obligations with respect to any Collateral. 4. COLLATERAL. The term "COLLATERAL" means the following items and types of ---------- property --wherever located and now or in the future acquired or existing: . All of Debtor's Accounts, Chattel Paper, Documents, Equipment, General Intangibles, Instruments, Investment Property, Inventory, and Pledged Securities; and . All cash and noncash proceeds of any other Collateral, including, without limitation, all cash, accounts, general intangibles, documents, instruments, chattel paper, goods, and any other property received upon the sale or disposition of any other Collateral and all insurance proceeds of any kind paid at any time in connection with any other Collateral. 5. FRAUDULENT CONVEYANCE. Notwithstanding any contrary provision, --------------------- Debtor agrees that, if -- but for the application of this paragraph -- any of the Secured Obligation or the Security Interest would constitute a preferential transfer under 11 U.S.C. (S) 547, a fraudulent conveyance under 11 U.S.C. (S) 548, or a fraudulent conveyance or transfer under any state fraudulent conveyance, fraudulent transfer, or similar Governmental Requirement in effect from time to time (each a "FRAUDULENT CONVEYANCE"), then the Secured Obligation and Security Interest remains enforceable to the maximum extent possible without causing any of the Secured Obligation or the Security Interest to be a fraudulent conveyance, and this agreement is automatically amended to carry out the intent of this paragraph. 6. REPRESENTATIONS AND WARRANTIES. Debtor represents and warrants to ------------------------------ Secured Party on behalf of Lenders that: (a) Borrowing Base. Any item of Collateral submitted or represented -------------- to Secured Party as being eligible under the Credit Agreement to be included in the Borrowing Base fully meets the requirements for eligibility provided in the Credit Agreement. 3 (b) Binding Obligation. This agreement creates a legal, valid, and ------------------ binding Lender Lien in and to the Collateral (subject to delivery to Secured Party of the stock certificates for the Pledged Securities) in favor of Secured Party and enforceable against Debtor. For Collateral in which the Security Interest may be perfected by the filing of Financing Statements, once those Financing Statements have been properly filed in the jurisdictions described on SCHEDULE 7.1 to the Credit Agreement, the Security Interest in that Collateral will be fully perfected. For the Pledged Securities, the taking by Secured Party of physical possession in Texas of Documents, Instruments, Chattel Paper, and the stock certificates representing the Pledged Securities will perfect the Security Interest in that Collateral. Once perfected, the Security Interest will constitute a first-priority Lender Lien on the Collateral, subject only to Permitted Liens. The creation of the Security Interest does not require the consent of any Person that has not been obtained. (c) Locations. The attached ANNEX 1 accurately describes (i) the --------- location of Debtor's principal place of business and chief executive office, (ii) if different from CLAUSE (I), the one or more locations of its books and records concerning its Accounts, (iii) the locations where any of its Inventory and Equipment (except when temporarily in the hands of a third-party contractor for processing and until sold in the ordinary course of business) is currently and will -- subject to PARAGRAPH 7(A) below -- in the future be maintained. Except as stated in CLAUSE (III) above, Debtor's Inventory is currently and will be in its possession. All Instruments and Chattel Paper have been delivered to Secured Party. (d) Accounts. Debtor's Accounts (i) arise from its sales or rendition -------- of services, (ii) are due to Debtor, and (iii) are not, if represented to be eligible for inclusion in the Borrowing Base, subject to any material setoff, counterclaim, defense, allowance, adjustment (other than discounts for prompt payment shown on the invoice), or material dispute, objection, or complaint by any Obligor. (e) Securities. All Pledged Securities are duly authorized, validly ---------- issued, fully paid, and non-assessable, and the transfer of them is not subject to any restrictions other than restrictions imposed by applicable Governmental Requirements. (f) Additional Collateral. The foregoing representations and --------------------- warranties will be true and correct in all respects with respect to any additional Collateral or additional specific descriptions of certain Collateral delivered to Secured Party in the future by Debtor. The failure of any of these representations or warranties to be accurate and complete does not impair the Security Interest in any Collateral. 7. COVENANTS. While any Lender is committed to lend or extend credit --------- under the Credit Agreement and until the Secured Obligation is fully paid and performed, Debtor covenants and agrees with Secured Party on behalf of Lenders that, without first obtaining Secured Party's written notice of Required Lenders' consent to the contrary: (a) Certain Relocations and Changes. Debtor shall give Secured Party ------------------------------- 30-days-written notice before any proposed (i) relocation of its principal place of business or chief executive office, (ii) change of its name, (iii) relocation of the place where its books and records concerning its Accounts are kept, and (iv) relocation of any Collateral (other than delivery of Inventory in the ordinary course of business to third-party contractors for processing and sales of Inventory in the ordinary course of business or as permitted by the Credit Agreement) to a location not described on the attached ANNEX 1. 4 (b) Estoppel and Other Agreements and Matters. Debtor shall: ----------------------------------------- (i) With respect to any of its Inventory that is Eligible Demonstration Systems and is in the possession of any customer of Debtor solely for demonstration purposes, deliver to Secured Party a bailee and estoppel agreement in substantially the form of EXHIBIT C-5 to the Credit Agreement providing that such customer or potential customer holds that Inventory as Secured Party's bailee, claims no ownership interest in that Inventory, will release that Inventory only to Debtor or Secured Party, and acknowledges that such Inventory is not and shall not become fixtures, and is not and shall not become subject to any Lien imposed by that customer, which agreement must otherwise be in form and substance reasonably acceptable to Secured Party and its special counsel; and (ii) Either (A) cause the landlord or lessor for each location where any of its Inventory is maintained to execute and deliver to Secured Party an estoppel and subordination agreement in substantially the form of EXHIBIT C-4 to the Credit Agreement or such other form as may be reasonably acceptable to Secured Party and its special counsel, or (B) deliver to Secured Party a legal opinion or other evidence (in each case that is reasonably satisfactory to Secured Party and it special counsel) that neither the applicable lease nor the Governmental Requirements of the jurisdiction in which that location is situated provide for contractual, common law, or statutory landlord's Liens that is senior to the Security Interest. (c) Other Notices and Actions. Debtor shall promptly notify Secured ------------------------- Party of (i) any change in any material fact or circumstance represented or warranted by Debtor with respect to any of the Collateral, and (ii) any claim, action, or proceeding challenging the Security Interest or affecting title to all or any material portion of the Collateral or the Security Interest (and, at Secured Party's request, Debtor shall appear in and defend any such action or proceeding at Debtor's expense). In case of any default or event of default by any other party under or in connection with any material portion (individually or collectively) of the Collateral, Debtor shall immediately use reasonable efforts to remedy the same or immediately demand that the same be remedied), (d) Record of Collateral. Debtor shall maintain at its chief executive -------------------- office a current record of where all of its Collateral is located and permit Secured Party or its representatives to inspect and make copies from those records pursuant to the Credit Agreement and furnish to Secured Party upon request, from time to time, such documents, lists, descriptions, certificates, and other information necessary or helpful to keep Secured Party informed with respect to the identity, location, status, condition, terms of, parties to, and value of the Collateral. (e) Collateral In Trust. While an Event of Default or Potential ------------------- Default exists, Debtor shall upon request of Secured Party (unless prevented by operation of applicable Governmental Requirements from making that request, in which event Debtor shall) (i) hold in trust (and not commingle with its other assets) for Secured Party all of its Collateral that is chattel paper, instruments, or documents of title at any time received by it, (ii) promptly deliver that Collateral to Secured Party unless Secured Party at its option gives Debtor written permission to retain any of it, and (iii) cause each chattel paper, instrument, or document of title so retained to be marked to state that it is assigned to Secured Party and each instrument to be endorsed to the order of Secured Party (but failure to be so marked or endorsed may not impair the Security Interest in any such Collateral). (f) Perform Obligation. Debtor shall perform all of its material ------------------ obligations under or in connection with all of its Collateral in accordance with customary business practices. 5 (g) Impairment of Collateral. Debtor shall not do or permit any act that is reasonably likely to adversely impair the value or usefulness any material portion of any Collateral. 8. REMEDIES UPON DEFAULT. While an Event of Default exists, Secured --------------------- Party is, subject to Credit Agreement, entitled to exercise any one or more of the following Rights. (a) Rights. Secured Party may exercise any and all Rights available ------ to a secured party under the UCC, in addition to any and all other Rights afforded by this agreement and the other Loan Documents, at law, in equity, or otherwise, including, without limitation (i) requiring Debtor to assemble Collateral and make it available to Secured Party at a place to be designated by Secured Party which is reasonably convenient to Debtor and Secured Party, (ii) applying by appropriate judicial proceedings for appointment of a receiver for Collateral, (iii) applying to the Secured Obligation any cash held by Secured Party under this agreement, (iv) reducing any claim to judgment, (v) exercising the Rights of offset or banker's Lien against the interest of Debtor in and to every account and other property of Debtor in Secured Party's possession to the extent of the full amount of the Secured Obligation, (vi) foreclosing the Security Interest and any other Liens Secured Party may have or otherwise realize upon any and all of the Rights Secured Party may have in and to Collateral, and (vii) bringing suit or other proceedings before any Governmental Authority either for specific performance of any covenant or condition contained in any of the Loan Documents or in aid of the exercise of any Right granted to Secured Party in any Loan Document. (b) Notice. If any Collateral threatens to decline speedily in value ------ or is of the type customarily sold on a recognized market, Secured Party may sell or otherwise dispose of that Collateral without notification, advertisement, or other notice of any kind. Otherwise, reasonable notice of the time and place of any public sale of the Collateral -- or reasonable notification of the time after which any private sale or other intended disposition of the Collateral is to be made -- shall be sent to Debtor and to any other Person entitled to notice under the UCC. Notice sent or given not less than ten calendar days prior to the taking of the action to which the notice relates is reasonable notice. It is not necessary that the Collateral be at the location of the sale. (c) Sales of Securities. In connection with the sale of any ------------------- Collateral that is securities, Secured Party is authorized, but not obligated, to limit prospective purchasers to the extent deemed necessary or desirable by Secured Party to render that sale exempt from the registration and similar requirements under applicable Governmental Requirements, and no sale so made in good faith by Secured Party may be deemed not to be "commercially reasonable" because so made. (d) Other Sales. Secured Party's sale of less than all Collateral ----------- does not exhaust Secured Party's Rights under this agreement and Secured Party is specifically empowered to make successive sales until all Collateral is sold. If the proceeds of a sale of less than all Collateral is less than the Secured Obligation, then this agreement and the Security Interest remain in full force and effect as to the unsold portion of the Collateral just as though no sale had been made. In the event any sale under this agreement is not completed or is, in Secured Party's opinion, defective, that sale does not exhaust Secured Party's Rights under this agreement, and Secured Party is entitled to cause a subsequent sale or sales to be made. All statements of fact or other recitals made in any bill of sale or assignment or other instrument evidencing any foreclosure sale under this agreement -- whether about nonpayment of the Secured Obligation, the occurrence of any Event of Default, Secured Party's having declared all of the Secured Obligation to be due and payable, notice of time, place, and terms of sale and the properties to be sold having been duly given, or any other act or thing having been duly done by Secured Party -- shall be taken as prima facie evidence of the truth of the facts so stated and recited. Secured Party may appoint or delegate any one or more Persons as agent to perform any act or acts necessary or incident to any sale 6 held by Secured Party, including the sending of notices and the conduct of sale, but such acts must be done in the name and on behalf of Secured Party. (e) Obligors. While an Event of Default exists, Secured Party may -------- notify or require each Obligor to make payment directly to Secured Party, and Secured Party may take control of the proceeds paid to Secured Party. Until Secured Party elects to exercise these Rights, Debtor is authorized to collect and enforce the Collateral and to retain and expend all payments made on Collateral. While Secured Party is entitled to and elects to exercise these Rights, Secured Party has the Right in its own name or in the name of Debtor to (i) compromise or extend time of payment with respect to Collateral for such amounts and upon such terms as Secured Party may reasonably determine, (ii) demand, collect, receive, receipt for, sue for, compound, and give acquittance for any and all amounts due or to become due with respect to Collateral, (iii) take control of cash and other proceeds of any Collateral, (iv) endorse Debtor's name on any notes, acceptances, checks, drafts, money orders, or other evidences of payment on Collateral that may come into Secured Party's possession, (v) sign Debtor's name on any invoice or bill of lading relating to any Collateral, on any drafts against Obligors or other Persons making payment with respect to Collateral, on assignments and verifications of accounts or other Collateral, and on notices to Obligors making payment with respect to Collateral, (vi) send requests for verification of obligations to any Obligor, and (vii) do all other acts and things reasonably necessary to carry out the intent of this agreement. If any Obligor fails to make payment on any Collateral when due while an Event of Default exists, Secured Party is authorized, in its sole discretion, either in its own name or in Debtor's name, to take such action as Secured Party reasonably shall deem appropriate for the collection of any amounts owed with respect to Collateral or upon which a delinquency exists. However, Secured Party is neither (x) liable for its failure to collect, or for its failure to exercise diligence in the collection of, any amounts owed with respect to Collateral (except for its own fraud, gross negligence, willful misconduct, or violation of any applicable Governmental Requirement), nor (y) under any duty whatever to anyone except Debtor and Lenders to account for funds that it shall actually receive under this agreement. A receipt given by Secured Party to any Obligor is a full and complete release, discharge, and acquittance to that Obligor, to the extent of any amount so paid to Secured Party. While an Event of Default exists, Secured Party may apply or set off amounts paid and the deposits against any liability of Debtor to Secured Party. Regarding the existence of any Event of Default for purposes of this agreement, Debtor agrees that the Obligors on any Collateral may rely upon written certification from Secured Party that an Event of Default exists. (f) Power-of-Attorney. Secured Party is deemed to be irrevocably ----------------- appointed as Debtor's agent and attorney-in-fact with all Right to enforce all of Debtor's Rights under or in connection with the Collateral effective and operable at all times while an Event of Default exists. All reasonable costs, expenses, and liabilities incurred and all payments made by Secured Party as Debtor's agent and attorney-in-fact (including, without limitation, reasonable attorney's fees and expenses) are considered a loan by Secured Party to Debtor that is repayable on demand, accrues interest at the Default Rate until paid, and is part of the Secured Obligation. (g) Application of Proceeds. While an Event of Default exists, ----------------------- Secured Party shall apply the proceeds of any sale or other disposition of Collateral in the following order: (i) Payment of all its reasonable expenses incurred in retaking, holding, and preparing any Collateral for disposition, in arranging for such disposition, and in actually disposing of the same (all of which are part of the Secured Obligation); (ii) repayment of amounts reasonably expended by Secured Party under PARAGRAPH 9 below; (iii) payment of the balance of the Secured Obligation in the order and manner specified in the Credit Agreement; and (iv) delivery either (A) to Debtor for its account or (B) as a court of competent jurisdiction may direct. 7 9. OTHER RIGHTS. ------------ (a) Performance. If Debtor fails to preserve the priority (subject to ----------- Permitted Liens) of the Security Interest in any Collateral or otherwise fails to perform any of its obligations under any Loan Document with respect to any Collateral, then Secured Party may, at its option, but without being required to do so, after five Business Days or earlier, if Secured Party in its reasonable judgment deems it necessary, prosecute or defend any suits in relation to the Collateral or take any other action that Debtor is required -- but has failed -- to take. Any amount that is reasonably expended or paid by Secured Party in connection with the foregoing (including, without limitation, court costs and reasonable attorneys' fees and expenses) bears interest at the Default Rate from the date spent or incurred until repaid and is payable (with that interest) by Debtor to Secured Party upon demand and is part of the Secured Obligation. (b) Collateral in Secured Party's Possession. If, while an Event of ---------------------------------------- Default exists, any Collateral comes into Secured Party's possession, Secured Party may use that Collateral for the purpose of preserving it or its value pursuant to the order of a court of appropriate jurisdiction or in accordance with any other Rights held by Secured Party in respect of that Collateral. Debtor covenants to promptly reimburse and pay to Secured Party, at Secured Party's request, the amount of all reasonable expenses, costs, Taxes, and other charges incurred by Secured Party in connection with its custody and preservation of that Collateral, all of which bear interest at the Default Rate from the date spent or incurred until repaid and are (with that interest) payable by Debtor to Secured Party upon demand and are part of the Secured Obligation. Except for Secured Party's own fraud, gross negligence, or willful misconduct (i) the risk of accidental loss or damage to, or diminution in value of, any Collateral is on Debtor, (ii) Secured Party has no liability for failure to obtain or maintain insurance or to determine whether any insurance in effect is adequate as to amount or risks insured, (iii) Secured Party has no duty to fix or preserve Rights against any Obligors in respect of any Collateral and is never liable for any failure to use diligence to collect any amount payable in respect of any Collateral (other than to account to Debtor and Lenders for what Secured Party may actually collect or receive). (c) Record Ownership of Securities. While an Event of Default exists, ------------------------------ Secured Party may have any Collateral that is securities and that is in the possession of Secured Party, or its nominee or nominees, registered in its name, or in the name of its nominee or nominees, as pledgee. (d) Voting of Securities. As long as no Event of Default exists, -------------------- Debtor may exercise all voting Rights pertaining to any Collateral that is securities. While an Event of Default exists, the Right to vote any Collateral that is securities is vested exclusively in Secured Party. Accordingly, Debtor irrevocably constitutes and appoints Secured Party as Debtor's proxy and attorney-in-fact -- effective only after notice to Debtor while an Event of Default exists but with full power of substitution -- to vote, and to act with respect to, any Collateral that is securities standing in the name of Debtor or with respect to which Debtor is entitled to vote and act. That proxy is coupled with an interest, is irrevocable, and continues until the Secured Obligation is fully paid and performed. (e) Certain Proceeds. The provisions of this CLAUSE (E) are applicable ---------------- only while an Event of Default exists. Notwithstanding any contrary provision, all dividends or distributions of property in respect of, and all proceeds of, any Collateral that is securities -- whether those dividends, distributions, or proceeds result from a subdivision, combination, or reclassification of the outstanding capital stock of any issuer or as a result of any merger, consolidation, acquisition, or other exchange of assets to which any issuer may be a party, or otherwise -- are part of the Collateral, shall, if received by Debtor, be held in trust for Secured Party's benefit, and shall immediately be delivered to Secured Party (accompanied by proper instruments of assignment or stock or bond powers executed by Debtor in accordance with Secured Party's instructions) to be held subject to the terms of this agreement. Any cash proceeds of any 8 Collateral that come into Secured Party's possession (including, without limitation, insurance proceeds) may, at Secured Party's option, be applied in whole or in part to the Secured Obligation (to the extent then due), be fully or partially released to or under the written instructions of Debtor for any general or specific purpose, or be fully or partially retained by Secured Party as additional Collateral. Any cash Collateral in Secured Party's possession may be invested by Secured Party in certificates of deposit issued by Secured Party, any Lender, or any other state or national bank having combined capital and surplus greater than $100,000,000 or in securities issued or guaranteed by the United States of America or any of its agencies. Secured Party is never obligated to make any investment and never has any liability to Debtor or any Lender for any loss that may result from any investment or non-investment. All interest and other amounts earned from any investment may be dealt with by Secured Party in the same manner as other cash Collateral. (f) INDEMNIFICATION. DEBTOR ASSUMES ALL LIABILITY FOR ALL COLLATERAL, --------------- FOR THE SECURITY INTEREST, AND FOR ANY USE, POSSESSION, MAINTENANCE, AND MANAGEMENT OF, ALL COLLATERAL (INCLUDING, WITHOUT LIMITATION, ANY TAXES ARISING AS A RESULT OF, OR IN CONNECTION WITH, THE TRANSACTIONS CONTEMPLATED IN THIS AGREEMENT) AND AGREES TO ASSUME LIABILITY FOR, AND TO INDEMNIFY AND HOLD SECURED PARTY, EACH LENDER, AND THEIR RESPECTIVE REPRESENTATIVES (THE "INDEMNIFIED ----------- PARTIES") HARMLESS FROM AND AGAINST, AND DEFEND EACH INDEMNIFIED PARTY AGAINST, - ------- ALL CLAIMS, CAUSES OF ACTION, OR LIABILITY, FOR INJURIES TO OR DEATHS OF PERSONS AND DAMAGE TO PROPERTY HOWSOEVER ARISING FROM OR INCIDENT TO SUCH USE, POSSESSION, MAINTENANCE, AND MANAGEMENT (WHETHER SUCH PERSONS BE AGENTS OR EMPLOYEES OF DEBTOR OR OF THIRD PARTIES, OR SUCH DAMAGE BE TO PROPERTY OF DEBTOR OR OF OTHERS) AND ALL CLAIMS, COSTS, PENALTIES, LIABILITIES, AND EXPENSES, INCLUDING, WITHOUT LIMITATION, COURT COSTS AND ATTORNEYS' FEES, HOWSOEVER ARISING OR INCURRED BECAUSE OF, INCIDENT TO, OR WITH RESPECT TO COLLATERAL OR ANY USE, POSSESSION, MAINTENANCE, OR MANAGEMENT OF IT. (THE "INDEMNIFIED ----------- LIABILITIES"). HOWEVER, NO INDEMNIFIED PARTY IS ENTITLED TO INDEMNITY UNDER THIS - ----------- PARAGRAPH FOR ITS OWN GROSS NEGLIGENCE, WILLFUL MISCONDUCT, OR FRAUD OR FOR ANY INDEMNIFIED LIABILITY ARISING FROM ITS ACTIONS AFTER SECURED PARTY HAS FORECLOSED THE SECURITY INTEREST OR ACCEPTED CONVEYANCE IN LIEU OF FORECLOSURE OR (EXCEPT FOR THE PLEDGED SECURITIES) TAKEN POSSESSION OF ANY COLLATERAL. The ------ provisions of this paragraph survive the payment and performance of the Secured Obligation and the release of the Security Interest. The foregoing indemnity shall be subject to the provisions of Section 9.12 of the Credit Agreement. (10) MISCELLANEOUS. ------------- (a) Term. This agreement terminates when no Lender has any commitment ---- to lend or extend credit under the Credit Agreement and the Secured Obligation is fully paid and performed. No Obligor on any Collateral is obligated to inquire about the termination of this agreement and is fully protected in making payments directly to Secured Party if SECTION 8(E) applies, which payments Secured Party shall pay to Debtor after termination of this agreement. (b) No Release. Neither the Security Interest, Debtor's obligations, ---------- nor Secured Party's or any Lenders' Rights under this agreement are released, diminished, impaired, or adversely affected by the occurrence of any one or more of the following events: (i) The taking or accepting of any other security or assurance for any Secured Obligation; (ii) any release, surrender, exchange, subordination, or loss of any security or assurance at any time existing in connection with any Secured Obligation; (iii) the modification of, amendment to, or waiver of compliance with any terms of any other Loan Document without the consent of Debtor except as required in that Loan Document; (iv) any present or future insolvency, bankruptcy, or lack of corporate or trust power of any party at any time liable for the payment 9 of any Secured Obligation; (v) except as specifically required by any other Loan Document, any renewal, extension, or rearrangement of the payment of any Secured Obligation (either with or without notice to or consent of Debtor) or any adjustment, indulgence, forbearance, or compromise that may be granted or given by Secured Party or any Lender to Debtor; (vi) any neglect, delay, omission, failure, or refusal of Secured Party or any Lender to take or prosecute any action in connection with any agreement, document, guaranty, or instrument evidencing, securing, or assuring the payment of any Secured Obligation; (vii) any failure of Secured Party or any Lender to notify Debtor of any renewal, extension, or assignment of any Secured Obligation, or the release of any security under any other document or instrument, or of any other action taken or refrained from being taken by Secured Party or any Lender against Debtor, or any new agreement between Secured Party, any Lender, and Debtor, it being understood that, except as expressly required by the Credit Agreement, neither Secured Party nor any Lender is required to give Debtor any notice of any kind under any circumstances whatsoever with respect to or in connection with the Secured Obligation, including, without limitation, notice of acceptance of this agreement or any Collateral ever delivered to or for the account of Secured Party under this agreement; (viii) the illegality, invalidity, or unenforceability of any Secured Obligation against any third party obligated with respect to it by reason of the fact that the Secured Obligation, or the interest paid or payable with respect to any of it, exceeds the amount permitted by applicable Governmental Requirements, the act of creating any of it is ultra vires, or the officers, partners, or trustees creating any of it acted in excess of their authority, or for any other reason; or (ix) if any payment by any party obligated with respect to any Secured Obligation is held to constitute a preference under applicable Laws or for any other reason Secured Party or any Lender is required to refund any payment on any Secured Obligation or pay the amount of it to someone else. (c) Waivers. To the maximum extent lawful, except to the extent ------- expressly otherwise provided in this agreement or in any other Loan Document, Debtor waives (i) any Right to require Secured Party or any Lender to proceed against any other Person, to exhaust Rights in Collateral, or to pursue any other Right that Secured Party or any Lender may have; (ii) with respect to the Secured Obligation, presentment and demand for payment, protest, notice of protest and nonpayment, notice of acceleration, and notice of intent to accelerate; and (iii) all Rights of marshaling in respect of any Collateral. (d) Financing Statement. Secured Party may at any time file this ------------------- agreement (or a carbon, photographic, or other reproduction of this agreement) as a financing statement, but the failure of Secured Party to do so does not impair the validity or enforceability of this agreement. (e) Information. Except as otherwise provided by applicable ----------- Governmental Requirements, Secured Party's charge for furnishing each statement of account or each list of Collateral is $10.00. (f) Loan Document. This agreement is a Loan Document and is subject ------------- to the applicable provisions of SECTIONS 1 and 17 of the Credit Agreement, all of which are incorporated in this agreement by reference the same as if set forth in this agreement verbatim. (g) Amendments, Etc. No amendment, waiver, or discharge to or under --------------- this agreement is valid unless it is in writing and is signed by the party against whom it is sought to be enforced and is otherwise in conformity with the requirements of SECTION 17.8 of the Credit Agreement. (h) ENTIRETY. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS TO WHICH -------- DEBTOR IS PARTY REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BY THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. 10 (i) Secured Party and Lenders. Secured Party is the administrative ------------------------- agent for each Lender under the Credit Agreement. The Security Interest and all Rights granted to Secured Party under or in connection with this agreement are for each Lender's ratable benefit. Secured Party may, without the joinder of any Lender, exercise any Rights in Secured Party's or Lenders' favor under or in connection with this agreement, including, without limitation, conducting any foreclosure sales and executing full or partial releases of, amendments or modifications to, or consents or waivers under this agreement. Secured Party's and each Lender's Rights and obligations vis-a-vis each other may be subject to one or more separate agreements between those parties. However, Debtor need not inquire about any such agreement and is not subject to any terms of it. Therefore, neither Debtor nor its successors or assigns is entitled to any benefits or provisions of any such separate agreement or is entitled to rely upon or raise as a defense any party's failure or refusal to comply with the provisions of it. (j) Parties. This agreement benefits Secured Party, Lenders, and ------- their respective successors and assigns and binds Debtor and its successors and assigns. Upon appointment of any successor Administrative Agent under the Credit Agreement, all of the Rights of Secured Party under this agreement automatically vests in that new Administrative Agent as successor Secured Party on behalf of Lenders without any further act, deed, conveyance, or other formality other than that appointment. The Rights of Secured Party and Lenders under this agreement may be transferred with any assignment of the Secured Obligation. The Credit Agreement contains provisions governing assignments of the Secured Obligation and of Rights and obligations under this agreement. REMAINDER OF PAGE INTENTIONALLY BLANK.

Central Expressway Dallas, Texas 75243 - ---------------------------------------------------------------------------------------------------------------------------------- GUARANTY -------- THIS GUARANTY is executed as of the date last stated below by each of the undersigned as a "Guarantor" (whether one or more, "GUARANTORS"), for the benefit of NATIONSBANK OF TEXAS, N.A., a national banking association (in its capacity as Administrative Agent for the Lenders now or in the future party to the Credit Agreement described below, "ADMINISTRATIVE AGENT"). Plasma & Materials Technologies, Inc. ("US BORROWER"), Electrotech Limited and Electrotech Equipments Limited (collectively, "UK BORROWERS"), Administrative Agent, Lloyds Bank Plc, as "UK-Collateral Agent," and certain Lenders have executed the Credit Agreement (as renewed, extended, amended, or restated, the "CREDIT AGREEMENT") dated as of November 15, 1996. US Borrower and UK Borrowers are collectively referred to in this guaranty as "BORROWERS." This guaranty is integral to the transactions contemplated by the Loan Documents and is a condition precedent to Lenders' obligations to extend or to continue to extend credit under the Credit Agreement. ACCORDINGLY, for adequate and sufficient consideration, each Guarantor jointly and severally guarantees to Administrative Agent and Lenders the prompt payment of the Guaranteed Debt (defined below) at -- and at all times after -- its maturity (by acceleration or otherwise) as follows: 1. DEFINITIONS. Terms defined in the Credit Agreement have the same ----------- meanings when used -- unless otherwise defined -- in this guaranty. As used in this guaranty: ADMINISTRATIVE AGENT is defined in the preamble to this guaranty and includes its successor appointed under SECTION 16 of the Credit Agreement and acting as administrative agent for Lenders under the Loan Documents. BORROWER means any of the Borrowers described in the recitals to this guaranty and includes, without limitation, a Borrower as a debtor-in-possession, and any receiver, trustee, liquidator, conservator, custodian, or similar party appointed for a Borrower or for all or substantially all of a Borrower's assets under any Debtor Law. CREDIT AGREEMENT is defined in the recitals to this guaranty. GUARANTEED DEBT means the US Obligation and the UK Obligation, as defined in the Credit Agreement, and all present and future costs, attorneys' fees, and expenses reasonably incurred by Administrative Agent or any Lender to enforce any Borrower's, any Guarantor's, or any other obligor's payment of any of the US Obligation and the UK Obligation, including, without limitation (to the extent lawful), all present and future amounts that would become due but for the operation of (S)(S) 502 or 506 or any other provision of Title 11 of the United States Code and all present and future accrued and unpaid interest (including, without limitation, all post-petition interest if any Borrower or any Subsidiary voluntarily or involuntarily becomes subject to any Debtor Law). GUARANTORS is defined in the preamble to this guaranty. SUBORDINATED DEBT means all present and future obligations of any Borrower to any Guarantor, whether those obligations are (a) direct, indirect, fixed, contingent, liquidated, unliquidated, joint, several, or joint and several, (b) due or to become due to any Guarantor, (c) held by or are to be held by any Guarantor, (d) created directly or acquired by assignment or otherwise, or (e) evidenced in writing. 2. GUARANTY. This is an absolute, irrevocable, and continuing guaranty, -------- and the circumstance that at any time or from time to time the Guaranteed Debt may be paid in full does not affect the obligation of any Guarantor with respect to the Guaranteed Debt incurred after that. This guaranty remains in effect until the Guaranteed Debt is fully paid and performed and all commitments to extend any credit under the Credit Agreement have terminated. No Guarantor may rescind or revoke its obligations with respect to the Guaranteed Debt. Notwithstanding any contrary provision in this guaranty, however, each Guarantor's maximum liability under this guaranty is limited, to the extent, if any, required so that its liability is not subject to avoidance under any Debtor Law. 3. CONSIDERATION. Each Guarantor represents and warrants that (a) the ------------- value of the consideration received and to be received by it is reasonably worth at least as much as its liability under this guaranty and (b) such liability may reasonably be expected to directly or indirectly benefit it. 4. CUMULATIVE RIGHTS. If any Guarantor becomes liable for any ----------------- indebtedness owing by any Borrower to Administrative Agent or any Lender, other than under this guaranty, that liability may not be in any manner impaired or affected by this guaranty. The Rights of Administrative Agent or Lenders under this guaranty are cumulative of any and all other Rights that Administrative Agent or Lenders may ever have against each Guarantor. The exercise by Administrative Agent or Lenders of any Right under this guaranty or otherwise does not preclude the concurrent or subsequent exercise of any other Right. 5. PAYMENT UPON DEMAND. If an Event of Default exists, each Guarantor ------------------- shall -- on demand and without further notice of dishonor and without any notice having been given to any Guarantor previous to that demand of either the acceptance by Administrative Agent or Lenders of this guaranty or the creation or incurrence of any Guaranteed Debt -- pay the amount of the Guaranteed Debt then due and payable to Administrative Agent and Lenders. It is not necessary for Administrative Agent or Lenders, in order to enforce that payment by any Guarantor, first or contemporaneously to institute suit or exhaust remedies against any Borrower or others liable on any Guaranteed Debt or to enforce Rights against any collateral securing any Guaranteed Debt. 6. SUBORDINATION. The Subordinated Debt is expressly subordinated to the ------------- full and final payment of the Guaranteed Debt. Each Guarantor agrees not to accept any payment of any Subordinated Debt from any Borrower if an Event of Default exists. If any Guarantor receives any payment of any Subordinated Debt in violation of the foregoing, that Guarantor shall hold that payment in trust for Administrative Agent and Lenders and promptly turn it over to Administrative Agent, in the form received (with any necessary endorsements), to be applied to the Guaranteed Debt. 7. SUBROGATION AND CONTRIBUTION. Until no Lender is obligated to lend or ---------------------------- issue BGs or LCs under the Credit Agreement and the Guaranteed Debt has been fully paid and performed (a) no Guarantor may assert, enforce, or otherwise exercise any Right of subrogation to any of the Rights or Liens of Administrative Agent or Lenders or any other beneficiary against Borrower or any other obligor on the Guaranteed Debt or any collateral or other security or any Right of recourse, reimbursement, subrogation, contribution, indemnification, or similar Right against Borrower or any other obligor on any Guaranteed Debt or any guarantor of it, (b) each Guarantor defers all of the foregoing Rights (whether they arise in equity, under contract, by statute, under common law, or otherwise), and (c) each Guarantor defers the benefit of, and any Right to participate in, any collateral or other security given to Administrative Agent or Lenders or any other beneficiary to secure payment of any Guaranteed Debt. 8. NO RELEASE. No Guarantor's obligations under this guaranty may be ---------- released, diminished, or affected by the occurrence of any one or more of the following events: (a) Any taking or accepting of any other security or assurance for any Guaranteed Debt; (b) any release, surrender, exchange, 2 subordination, impairment, or loss of any collateral securing any Guaranteed Debt; (c) any full or partial release of the liability of any other obligor on the US Obligation or the UK Obligation; (d) the modification of, or waiver of compliance with, any terms of any other Loan Document; (e) the insolvency, bankruptcy, or lack of corporate or partnership power of any other obligor at any time liable for any Guaranteed Debt, whether now existing or occurring in the future; (f) any renewal, extension, or rearrangement of any Guaranteed Debt or any adjustment, indulgence, forbearance, or compromise that may be granted or given by Administrative Agent or any Lender to any other obligor on the US Obligation or the UK Obligation; (g) any neglect, delay, omission, failure, or refusal of Administrative Agent or any Lender to take or prosecute any action in connection with the Guaranteed Debt; (h) any failure of Administrative Agent or any Lender to notify any Guarantor of any renewal, extension, or assignment of any Guaranteed Debt, or the release of any security or of any other action taken or refrained from being taken by Administrative Agent or any Lender against any Borrower or any new agreement between Administrative Agent, any Lender, and any Borrower, it being understood that neither Administrative Agent nor any Lender is required to give any Guarantor any notice of any kind under any circumstances whatsoever with respect to or in connection with any Guaranteed Debt, other than any notice required to be given to Guarantors by Law or elsewhere in this guaranty; (i) the unenforceability of any Guaranteed Debt against any other obligor 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 (j) any payment of the US Obligation or the UK Obligation to Administrative Agent or Lenders is held to constitute a preference under any Debtor Law or for any other reason Administrative Agent or any Lender is required to refund that payment or make payment to someone else (and in each such instance this guaranty will be reinstated in an amount equal to that payment). 9. WAIVERS. To the maximum extent lawful, each Guarantor waives all ------- Rights by which it might be entitled to require suit on an accrued right of action in respect of any Guaranteed Debt or require suit against any Borrower or others, whether arising under (S) 34.02 of the Texas Business and Commerce Code, as amended (regarding its Right to require Administrative Agent or Lenders to sue any Borrower on accrued right of action following its written notice to Administrative Agent or Lenders), (S) 17.001 of the Texas Civil Practice and Remedies Code, as amended (allowing suit against it without suit against a Borrower, but precluding entry of judgment against it before entry of judgment against that Borrower), Rule 31 of the Texas Rules of Civil Procedure, as amended (requiring Administrative Agent or Lenders to join a Borrower in any suit against it unless judgment has been previously entered against that Borrower), or otherwise. 10.

RELIANCE AND DUTY TO REMAIN INFORMED. Each Guarantor confirms that it ------------------------------------ has executed and delivered this guaranty after reviewing the terms and conditions of the Loan Documents and such other information as it has deemed appropriate in order to make its own credit analysis and decision to execute and deliver this guaranty. Each Guarantor confirms that it has made its own independent investigation with respect to Borrower's creditworthiness and is not executing and delivering this guaranty in reliance on any representation or warranty by Administrative Agent or any Lender as to that creditworthiness. Each Guarantor expressly assumes all responsibilities to remain informed of the financial condition of Borrowers and any circumstances affecting Borrowers' ability to perform under the Loan Documents to which it is a party or any collateral securing any Guaranteed Debt. 3 12. NO REDUCTION. The Guaranteed Debt may not be reduced, discharged, or ------------ released because or by reason of any existing or future offset, claim, or defense (except for the defense of complete and final payment of the Guaranteed Debt) of any Borrower or any other obligor against Administrative Agent or Lenders or against payment of the Guaranteed Debt, whether that offset, claim, or defense arises in connection with the Guaranteed Debt or otherwise. Those claims and defenses include, without limitation, failure of consideration, breach of warranty, fraud, bankruptcy, incapacity/infancy, statute of limitations, lender liability, accord and satisfaction, usury, forged signatures, mistake, impossibility, frustration of purpose, and unconscionability. 13. VENUE AND SERVICE OF PROCESS. EACH GUARANTOR (A) IRREVOCABLY SUBMITS ---------------------------- TO THE NONEXCLUSIVE JURISDICTION OF ANY TEXAS STATE OR FEDERAL COURT, (B) IRREVOCABLY WAIVES -- TO THE FULLEST EXTENT PERMITTED BY LAW -- ANY OBJECTION THAT IT MAY NOW OR IN THE FUTURE HAVE TO THE LAYING OF VENUE OF ANY LITIGATION BROUGHT IN CONNECTION WITH ANY LOAN DOCUMENT OR THE GUARANTEED DEBT BROUGHT IN DISTRICT COURTS OF DALLAS COUNTY, TEXAS, OR IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF TEXAS, DALLAS DIVISION, (C) IRREVOCABLY WAIVES ANY CLAIMS THAT ANY LITIGATION BROUGHT IN ANY OF THOSE COURTS HAS BEEN BROUGHT IN AN INCONVENIENT FORUM, (D) IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THOSE COURTS IN ANY LITIGATION BY THE MAILING OF COPIES OF THAT LEGAL PROCESS BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED, POSTAGE PREPAID, BY HAND- DELIVERY, OR BY DELIVERY BY A NATIONALLY RECOGNIZED COURIER SERVICE, AND SERVICE IS DEEMED COMPLETE UPON DELIVERY OF THE LEGAL PROCESS AT ITS ADDRESS AS PROVIDED IN THIS GUARANTY, AND (E) IRREVOCABLY AGREES THAT ANY LEGAL PROCEEDING AGAINST ANY PARTY TO ANY LOAN DOCUMENT ARISING OUT OF OR IN CONNECTION WITH THE LOAN DOCUMENTS OR THE GUARANTEED DEBT MAY BE BROUGHT IN ONE OF THOSE COURTS. The scope of each of these 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. These waivers are a material inducement to the agreement by Administrative Agent and each Lender to enter into the Loan Documents, and they have each relied -- and may continue to rely -- on these waivers in its dealings with Guarantors. Each Guarantor represents and warrants that it has reviewed these waivers with its legal counsel, and that it knowingly and voluntarily agrees to each waiver following consultation with legal counsel. These waivers are irrevocable, may not be modified either orally or in writing, and apply to any renewals, extensions, amendments, and replacements of any Loan Document. 14. LOAN DOCUMENT. This guaranty is a Loan Document and is subject to the ------------- applicable provisions of SECTIONS 1 and 17 of the Credit Agreement, all of which are incorporated into this guaranty by reference the same as if set forth in this guaranty verbatim. 15. COMMUNICATIONS. For purposes of SECTION 17.2 of the Credit Agreement, -------------- each Guarantor's address and telecopy number are the same as US Borrower's. 16. AMENDMENTS, ETC. No amendment, waiver, or discharge to or under this --------------- guaranty is valid unless it is in writing and is signed by the party against whom it is sought to be enforced and is otherwise in conformity with the requirements of SECTION 17.9 of the Credit Agreement. 17. ENTIRETY. THIS GUARANTY AND THE OTHER LOAN DOCUMENTS TO WHICH ANY -------- GUARANTOR IS A PARTY REPRESENT THE FINAL AGREEMENT BETWEEN THAT GUARANTOR, ADMINISTRATIVE AGENT, AND LENDERS WITH RESPECT TO THE SUBJECT MATTER OF THIS GUARANTY AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR 4 SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. 18. ADMINISTRATIVE AGENT AND LENDERS. Administrative Agent is the -------------------------------- Administrative Agent for each Lender under the Credit Agreement. All Rights granted to Administrative Agent under or in connection with this guaranty are for each Lender's ratable benefit. Administrative Agent may, without the joinder of any Lender, exercise any Rights in Administrative Agent's or Lenders' favor under or in connection with this guaranty. Administrative Agent's and each Lender's Rights and obligations vis-a-vis each other may be subject to one or more separate agreements between those parties. However, no Guarantor is required to inquire about any such agreement or is subject to any terms of it unless that Guarantor specifically joins it. Therefore, neither any Guarantor nor its successors or assigns is entitled to any benefits or provisions of any such separate agreement or is entitled to rely upon or raise as a defense any party's failure or refusal to comply with the provisions of it. 19. PARTIES. This guaranty benefits Administrative Agent, Lenders, and ------- their respective successors and assigns and binds each Guarantor and its successors and assigns. Upon appointment of any successor Administrative Agent under the Credit Agreement, all of the Rights of Administrative Agent under this guaranty automatically vests in that new Administrative Agent as successor Administrative Agent on behalf of Lenders without any further act, deed, conveyance, or other formality other than that appointment. The Rights of Administrative Agent and Lenders under this guaranty may be transferred with any assignment of the Guaranteed Debt. The Credit Agreement contains provisions governing assignments of the Guaranteed Debt and of Rights and obligations under this guaranty.
