For example, if there are two issuances of Junior Securities, one in the amount of $75,000,000 and a later one in the amount of $50,000,000, the Qualifying Date will be the date of the first issuance, which will also be the Achievement Date for the $75,000,000 level in EXHIBIT C, and the Preliminary Available Amount will be determined according to Table Four of EXHIBIT C until the date of the second issuance; the date of the second issuance will be the Achievement Date for the $125,000,000 level EXHIBIT C, and the Preliminary Available Amount will thereafter be determined according to Table Two of EXHIBIT F.

Any voluntary reduction in the Available Amount prior to any scheduled reduction in the Available Amount shall not affect the Available Amount after such scheduled reduction date unless such voluntarily reduced Available Amount is less than the amount scheduled to be the Available Amount after such scheduled reduction date, in which case the Available Amount after such scheduled reduction date shall be no greater than such voluntarily reduced Available Amount. Reference is made to SECTION 2.8 of the Amended and Restated Revolving Credit Agreement for restrictions on the Company's right to increase the Available Amount under certain circumstances. (c) NO REINSTATEMENT. No reduction in or termination of Commitments pursuant to this Section may be reinstated without the written approval of the Agent and all Banks. 2.4 SEVERAL OBLIGATIONS. The failure of any Bank to participate in any Letter of Credit shall not relieve any other Bank of its obligation to participate in any Letter of Credit (the face amount of which shall be reduced dollar for dollar by the amount of the share of the Bank that failed to participate in such Letter of Credit) on such date, but neither the Agent nor any Bank shall be responsible for the failure of any other Bank to participate in any Letter of Credit. 2.5 FEES. In consideration of the Commitments, the Company shall pay to the Agent for the account of each Bank in accordance with its Commitment Percentage commitment fees (the "COMMITMENT FEES") for the period from the date of the execution of this Agreement to and including the earlier of the date the Commitments are terminated or the Termination Date at a rate per annum equal to 1/2% of the Unused Commitment. The Company shall be entitled to credit on the Commitment Fees any amount paid pursuant to SECTION 2.3 of the Amended and Restated Revolving Credit Agreement. The Commitment Fees shall be computed for each day and shall be based on the Unused Commitment for such day. Accrued Commitment Fees shall be payable in arrears on the date of the initial Letter of Credit, within three days after demand therefor on or about the Quarterly Dates, and within three days after demand therefor on or about the Termination Date. All past due Commitment Fees shall bear interest at the Post-Default Rate. Upon receipt, the Agent shall disburse the Commitment Fees to the Banks in accordance with their Commitment Percentages. Section 3. PREPAYMENTS. 3.1 (a) COMMITMENT AMOUNT. The Company shall from time to time on demand by the Agent prepay the Facility B Loans or reduce -38- Letter of Credit Liabilities in such amounts as shall be necessary (A) so that at all times the aggregate outstanding principal amount of all Facility B Loans and all Letter of Credit Liabilities hereunder shall not be in excess of the aggregate of the Available Amount or (B) to comply with SECTION 9.9. Any such payment shall be allocated between Facility B Loans, Letter of Credit Liabilities (and if to Letter of Credit Liabilities, first, to Reimbursement Obligations) and other obligations as the Company may elect. (b) AVAILABLE AMOUNT. The Company shall from time to time on demand by the Agent and on the Termination Date prepay the Facility B Loans or reduce Letter of Credit Liabilities in such amounts as shall be necessary so that at all times the aggregate outstanding principal amount of all Facility B Loans and all Letter of Credit Liabilities of the Company hereunder shall be less than or equal to the Available Amount. Any such payment shall be allocated between Facility B Loans, Letter of Credit Liabilities (and if to Letter of Credit Liabilities, first, to Reimbursement Obligations) and then to other obligations as the Company may elect. Section 4. PAYMENTS OF PRINCIPAL AND INTEREST. 4.1 REPAYMENT OF REIMBURSEMENT OBLIGATIONS. The Company will pay to the Agent for the account of each Bank the amount of each Reimbursement Obligation forthwith upon its incurrence. The amount of any Reimbursement Obligation may, if the applicable conditions precedent specified in SECTION 7 of the Amended and Restated Revolving Credit Agreement have been satisfied, be paid with the proceeds of Facility B Loans. 4.2 INTEREST. Subject to SECTION 12.8, the Company will pay to the Agent for the account of each Bank interest on the unpaid principal amount of each Reimbursement Obligation owed to such Bank for the period commencing on the date such Reimbursement Obligation arises to but excluding the date such Reimbursement Obligation shall be paid in full, at the Post-Default Rate. Accrued interest shall be due and payable from time to time on demand of the Agent or the Required Banks (through the Agent). Section 5. PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS, ETC. 5.1 PAYMENTS. (a) Except to the extent otherwise provided herein, all payments of principal of or interest on the Reimbursement Obligations and other amounts to be made by the Company hereunder shall be made in dollars, in immediately available funds, to the Agent at its Principal Office (or in the case of a successor Agent, at the principal office of such successor Agent in the United States), not later than 11:00 a.m. on the date on which such payment shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day). -39- (b) The Company shall, at the time of making each payment hereunder, specify to the Agent the Reimbursement Obligations or other amounts payable by the Company hereunder to which such payment is to be applied (and in the event that it fails so to specify, such payment shall be applied as the Agent may designate to the amounts then due and payable); PROVIDED that if no Reimbursement Obligations are then due and payable or an Event of Default has occurred and is continuing, the Agent may apply such payment to the Obligations in such order as it may elect in its sole discretion, but subject to the other terms and conditions of this Agreement, including SECTION 5.2). Each payment received by the Agent hereunder for the account of a Bank shall be paid promptly to such Bank, in immediately available funds for the account of such Bank's Applicable Lending Office. (c) If the due date of any payment hereunder falls on a day which is not a Business Day, the due date for such payment shall be extended to the next succeeding Business Day and interest shall be payable for any principal so extended for the period of such extension. 5.2 PRO RATA TREATMENT. Except to the extent otherwise provided herein, (a) each issuance of a Letter of Credit and each termination or reduction of the Commitments of the Banks under SECTION 2.3 shall be made PRO RATA according to the Banks' respective Commitments; (b) each payment by the Company of principal of or interest on any Reimbursement Obligation shall be made to the Agent for the account of the Banks PRO RATA in accordance with the respective unpaid principal amounts of such Reimbursement Obligation held by the Banks; and (c) the Banks (other than the Agent) shall purchase from the Agent participations in the Letters of Credit in accordance with their respective Commitment Percentages. 5.3 COMPUTATIONS. Interest based on the Alternate Base Rate (to the extent determined by reference to the Prime Rate), and fees hereunder, will be computed on the basis of 365 (or 366) days and actual days elapsed (including the first day but excluding the last day) occurring in the period for which payable. All other interest shall be computed on the basis of a year of 360 days and actual days elapsed (including the first day but excluding the last day) occurring in the period for which payable, unless the effect of so computing shall be to cause the rate of interest to exceed the Highest Lawful Rate (in which event interest shall be calculated on the basis of the actual number of days elapsed in a year composed of 365 or 366 days, as the case may be). 5.4 MINIMUM AND MAXIMUM AMOUNTS. Each Letter of Credit shall be in a face amount at least equal to $100,000. 5.5 CERTAIN ACTIONS, NOTICES, ETC. Notices to the Agent of any termination or reduction of Commitments, prepayments under -40- SECTION 3.1 and requests for the issuance of Letters of Credit shall be irrevocable and shall be effective only if received by the Agent not later than 11:00 a.m. on the number of Business Days prior to the date of the relevant issuance, termination, reduction, and/or prepayment specified below: Number of Business Days Prior NOTICE Termination or reduction of Commitments 10 Issuance of Letters of Credit 5 Prepayments 1 Each such notice of termination or reduction shall specify the amount of the Commitments to be terminated or reduced. Each such notice of prepayment shall specify the amount to be prepaid (subject to SECTION 3.1) and the date of prepayment (which shall be a Business Day). The Agent shall promptly notify the Banks of the contents of each such notice or Application. Notice of any prepayment having been given, the principal amount specified in such notice, together with interest thereon to the date of prepayment, shall be due and payable on such prepayment date. 5.6 NON-RECEIPT OF FUNDS BY THE AGENT. Unless the Agent shall have been notified by a Bank prior to noon on the date on which such Bank is to make payment to the Agent of any amount to be paid by such Bank to reimburse the Agent for a drawing under any Letter of Credit or by the Company prior to the date on which the Company is to make a payment to the Agent for the account of one or more of the Banks, as the case may be (such Bank or the Company being herein called the "PAYOR" and such payment being herein called the "REQUIRED PAYMENT"), which notice shall be effective upon receipt, that the Payor does not intend to make the Required Payment to the Agent, the Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available to the intended recipient on the date that such Required Payment is to be made. If the Payor is the Company and the Company has not in fact made the Required Payment to the Agent on or before such date, the recipient of such payment (or, if the recipient is the beneficiary of a Letter of Credit, the Company, and, if the Company fails to pay the amount thereof to the Agent on demand, then the Banks, to the extent not already paid, ratably in proportion to their respective Commitment Percentages) shall, on demand, pay to the Agent the amount made available by the Agent, together with interest thereon from the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate per annum equal to the Fed Funds Rate for the first three days -41- after demand and thereafter at the Fed Funds Rate plus 2%. If the Payor is a Bank and such Bank has not in fact made the Required Payment to the Agent on or before such date, then such Bank shall pay to the Agent the amount made available by the Agent on behalf of such Bank, together with interest thereon from the date such amount was so made available by the Agent until the Agent recovers such amount at a rate per annum equal to the Fed Funds Rate for the first three days and thereafter at the Fed Funds Rate plus 2%. 5.7 SHARING OF PAYMENTS, ETC. If a Bank or any participant of a Bank shall obtain payment of any obligation to it under this Agreement, through the exercise of any right of set-off, banker's lien, counterclaim or similar right, or otherwise, then such Bank or participant shall promptly purchase from the other Banks participa- tions in the Reimbursement Obligations or other obligations held by the other Banks in such amounts, and make such other adjustments from time to time as shall be equitable to the end that all the Banks and participants shall share the benefit of such payment (net of any expenses which may be incurred by such Bank or its participant in obtaining or preserving such benefit) PRO RATA in accordance with the unpaid principal and interest on such obligations then due to each of them. To such end all the Banks and their participants shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. The Company agrees, to the fullest extent it may effectively do so under applicable law, that any Bank so purchasing a participation in the Reimbursement Obligations or other obligations held by other Banks may exercise all rights of set-off, bankers' lien, counterclaims or similar rights with respect to such participation as fully as if such Bank were a direct holder of Reimbursement Obligations or other obligations in the amount of such participation. Nothing contained herein shall require any Bank to exercise any such right or shall affect the right of any Bank to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of the Company. 5.8 OTHER EXPENSES. The Company agrees to pay the Agent, for the account of the Agent, the usual and customary charges of TCB for each extension, amendment and wire advice of and drawing under the Letters of Credit. Section 6. YIELD PROTECTION AND ILLEGALITY. 6.1 ADDITIONAL COSTS IN RESPECT OF LETTERS OF CREDIT. If as a result of any Regulatory Change there shall be imposed, modified or deemed applicable any tax, reserve, special deposit or similar requirement against or with respect to or measured by reference to Letters of Credit issued or to be issued hereunder and the result shall be to increase the cost to the Agent or any Bank of issuing or maintaining or participating in any Letter of Credit or reduce -42- any amount receivable by the Agent or any Bank hereunder in respect of any Letter of Credit or participation therein, then such Bank shall notify the Company through the Agent, and upon demand therefor by such Bank through the Agent, the Company (subject to SECTION 12.8) shall pay to the Agent or such Bank, from time to time as specified by the Agent or such Bank, such additional amounts as shall be sufficient to compensate the Agent or such Bank for such increased costs or reductions in amount. Before making such demand pursuant to this SECTION 6.1, the Agent or such Bank will designate a different available Applicable Lending Office for the Letter of Credit or participation or take such other action as the Company may request, if such designation or action will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of the Agent or such Bank, be disadvantageous to the Agent or such Bank. A statement as to such increased costs or reductions in amount incurred by the Agent or such Bank, submitted by the Agent or such Bank to the Company, shall cover amounts accruing under this section with respect to a period beginning not earlier than 120 days from the date thereof and be conclusive as to the amount thereof, absent manifest error. In the event any Bank shall seek compensation pursuant to this SECTION 6.1, the Company may give notice to such Bank (with copies to the Agent) that it wishes to seek one or more Eligible Assignees (which may be one or more of the Banks) to assume the Commitment of such Bank and to purchase and assume its outstanding Letter of Credit Liabilities. Each Bank requesting compensation pursuant to this SECTION 6.1 agrees to sell its Commitment and interest in this Agreement and in the Obligations and in the Amended and Restated Revolving Credit Agreement pursuant to SECTION 12.6 (without recourse, representation or warranty except as provided in SECTION 12.6) to any such Eligible Assignee for an amount equal to the sum of the outstanding unpaid principal of and accrued interest on such Obligations plus all other fees and amounts (including any compensation claimed by such Bank under this SECTION 6.1) owing to such Bank hereunder and under the Amended and Restated Revolving Credit Agreement calculated, in each case, to the date such Commitment, Obligations and interests are purchased, whereupon such Bank shall have no further Commitment or other obligation to the Company hereunder or under the Amended and Restated Revolving Credit Agreement. 6.2 CAPITAL ADEQUACY. If any Bank shall have determined that the adoption after the date hereof or effectiveness after the date hereof (regardless of whether previously announced) of any applicable Legal Requirement or treaty regarding capital adequacy, or any change after the date hereof in any existing or future Legal Requirement or treaty regarding capital adequacy, or any change in the interpretation or administration thereof after the date hereof by any Governmental Authority or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Applicable Lending Office) with any request or directive -43- after the date hereof regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority or comparable agency has or would have the effect of reducing the rate of return on the capital of such Bank (or any holding company of which such Bank is a part) as a consequence of its obligations hereunder and under or in respect of the Letters of Credit to a level below that which such Bank or holding company could have achieved but for such adoption, change or compliance by an amount deemed by such Bank to be material, then from time to time, upon demand by such Bank (with a copy to the Agent), the Company (subject to SECTION 12.8) shall pay to such Bank such additional amount or amounts as will compensate such Bank or holding company for such reduction. The certificate of any Bank setting forth such amount or amounts as shall be necessary to compensate it and the basis therefor shall cover amounts accruing under this SECTION 6.2 with respect to a period beginning not earlier than 120 days from the date thereof and shall be conclusive and binding, absent manifest error. The Company shall pay the amount shown as due on any such certificate upon delivery of such certificate. In preparing such certificate, a Bank may employ such assumptions and allocations of costs and expenses as it shall in good faith deem reasonable and may use any reasonable averaging and attribution method. In the event any Bank shall seek compensation pursuant to this SECTION 6.2, the Company may give notice to such Bank (with copies to the Agent) that it wishes to seek one or more Eligible Assignees (which may be one or more of the Banks) to assume the Commitment of such Bank and to purchase and assume its outstanding Letter of Credit Liabilities. Each Bank requesting compensation pursuant to this SECTION 6.2 agrees to sell its Commitment and interest in this Agreement and in the Obligations and in the Amended and Restated Revolving Credit Agreement pursuant to SECTION 12.6 (without recourse, representation or warranty except as provided in SECTION 12.6) to any such Eligible Assignee for an amount equal to the sum of the outstanding unpaid principal of and accrued interest on such Obligations plus all other fees and amounts (including any compensation claimed by such Bank under this SECTION 6.2) owing to such Bank hereunder and under the Amended and Restated Revolving Credit Agreement calculated, in each case, to the date such Commitment, Obligations, and interests are purchased, whereupon such Bank shall have no further Commitment or other obligation to the Company hereunder or under the Amended and Restated Revolving Credit Agreement.

Section 11. THE AGENT. 11.1 APPOINTMENT, POWERS AND IMMUNITIES. Each Bank hereby irrevocably appoints and authorizes the Agent to act as its Agent under the Credit Documents and under the Letters of Credit with such powers as are specifically delegated to the Agent by the terms thereof, together with such other powers as are reasonably incidental thereto, including the execution and delivery of the First Amendment to Deed of Trust (as that term is defined in the Amended and Restated Revolving Credit Agreement). The Agent (which term as used in this SECTION 11 shall include reference to its Affiliates and its own and its Affiliates' officers, directors, employees and agents) shall (a) have no duties or responsibilities except those expressly set forth in the Letters of Credit and the Credit Documents, and shall not by reason of any Credit Document be a trustee or fiduciary for any Bank; (b) not be responsible to any Bank for any recitals, statements, representations or warranties contained in any Credit Document, or in any certificate or other document referred to or provided for in, or received by any of them under, any Credit Document, or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of any Credit Document or any other document referred to or provided for therein or any property covered thereby or for any failure by the Company or any other Person to perform any of its obligations thereunder; (c) not be required to initiate or conduct any litigation or collection proceedings hereunder or under any Credit Document except to the extent requested by the Required Banks (and SECTION 11.7 shall apply), and (d) not be responsible for any action taken or omitted to be taken by it under any Credit Document -72- or any other document or instrument referred to or provided for therein or in connection therewith, including pursuant to its own negligence, except for its own gross negligence or willful misconduct. The Agent may employ agents and attorneys-in-fact and shall not be responsible for the negligence or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. Without in any way limiting any of the foregoing, each Bank acknowledges that the Agent shall have no greater responsibility in the operation of the Letters of Credit than is specified in the Uniform Customs and Practice of Documentary Credits (1993 Revision, International Chamber of Commerce Publication No. 500). 11.2 RELIANCE BY AGENT. The Agent shall be entitled to rely upon any certification, notice or other communication (including any thereof by telephone, telex, telegram or cable) believed by it to be genuine and correct and to have been signed or sent by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel (which may be counsel for the Company), independent accountants and other experts selected by the Agent. As to any matters not expressly provided for by any Credit Document, the Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and thereunder in accordance with instructions of the Required Banks, and any action taken or failure to act pursuant thereto shall be binding on all of the Banks. 11.3 DEFAULTS. The Agent shall not be deemed to have knowledge of the occurrence of a Default (other than the non-payment of principal of or interest on Reimbursement Obligations) unless it has received notice from a Bank or the Company specifying such Default and stating that such notice is a "Notice of Default". In the event that the Agent receives such a notice of the occurrence of a Default, the Agent shall give prompt notice thereof to the Banks (and shall give each Bank prompt notice of each such non-payment). The Agent shall (subject to SECTIONS 11.7 and 12.5) take such action with respect to such Default as shall be directed by all Banks or the Required Banks, as appropriate, and within its rights under the Credit Documents and at law or in equity; PROVIDED that, unless and until the Agent shall have received such directions, the Agent may (but shall not be obligated to) take such action, or refrain from taking such action, permitted hereby with respect to such Default as it shall deem advisable in the best interests of the Banks and within its rights under the Credit Documents, at law or in equity. 11.4 RIGHTS AS A BANK. With respect to their Commitments, the Letters of Credit and the Reimbursement Obligations, TCB and NationsBank in their capacities as Banks hereunder shall have the same rights and powers hereunder as any other Bank and may exercise the same as though they were not acting as the Agent or the Co-Agents, and the term "Bank" or "Banks" shall, unless the context otherwise indicates, include the Agent and the Co-Agents in their -73- individual capacity. The Agent and the Co-Agents may (without having to account therefor to any Bank) accept deposits from, lend money to and generally engage in any kind of banking, trust, letter of credit, agency or other business with the Company (and any of its Affiliates) as if they were not acting as the Agent and the Co-Agents, and the Agent and the Co-Agents may accept fees and other consideration from the Company and its Affiliates (in addition to the fees heretofore agreed to between the Company and the Agent or the Co-Agents) for services in connection with this Agreement or otherwise without having to account for the same to the Banks. 11.5 INDEMNIFICATION. THE BANKS AGREE TO INDEMNIFY THE AGENT (TO THE EXTENT NOT REIMBURSED UNDER SECTION 12.3 OR 12.4, BUT WITHOUT LIMITING THE OBLIGATIONS OF THE COMPANY UNDER SAID SECTIONS 12.3 AND 12.4), RATABLY IN ACCORDANCE WITH THEIR RESPECTIVE COMMITMENTS, FOR ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS OF ANY KIND AND NATURE WHATSOEVER (INCLUDING THE CONSEQUENCES OF THE NEGLIGENCE OF THE AGENT) WHICH MAY BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE AGENT IN ANY WAY RELATING TO OR ARISING OUT OF ANY CREDIT DOCUMENT (AS DEFINED HEREIN) OR ANY OTHER DOCUMENTS CONTEMPLATED BY OR REFERRED TO THEREIN OR THE TRANSACTIONS CONTEM- PLATED THEREBY (INCLUDING THE COSTS AND EXPENSES WHICH THE COMPANY IS OBLIGATED TO PAY UNDER SECTIONS 12.3 AND 12.4 BUT EXCLUDING, UNLESS A DEFAULT HAS OCCURRED AND IS CONTINUING, NORMAL ADMINISTRATIVE COSTS AND EXPENSES INCIDENT TO THE PERFORMANCE OF ITS AGENCY DUTIES HEREUNDER) OR THE ENFORCEMENT OF ANY OF THE TERMS HEREOF OR THEREOF OR OF ANY SUCH OTHER DOCUMENTS, INCLUDING THE NEGLIGENCE OF THE AGENT; PROVIDED THAT NO BANK SHALL BE LIABLE FOR ANY OF THE FOREGOING TO THE EXTENT THEY ARISE FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PARTY TO BE INDEMNIFIED. THE OBLIGATIONS OF THE BANKS UNDER THIS SECTION 11.5 SHALL SURVIVE THE TERMINATION OF THIS AGREEMENT. 11.6 NON-RELIANCE ON THE AGENT AND OTHER BANKS. Each Bank agrees that it has received current financial information with respect to the Company and that it has, independently and without reliance on the Agent, the Co-Agents or any other Bank and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Company and decision to enter into this Agreement and that it will, independently and without reliance upon the Agent, the Co-Agents or any other Bank, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under the Credit Documents. The Agent and the Co-Agents shall not be required to keep themselves informed as to the performance or observance by the Company of any Credit Document or any other document referred to or provided for therein or to inspect the property or books of the Company or any other Person. Except for notices, reports and other documents and information expressly required to be furnished to the Banks by the Agent and the Co-Agents under the Credit Documents, the Agent and the Co- -74- Agents shall not have any duty or responsibility to provide any Bank with any credit or other information concerning the affairs, financial condition or business of the Company (or any of its Affiliates) which may come into the possession of the Agent or either Co-Agent. 11.7 FAILURE TO ACT. Except for action expressly required of the Agent under the Credit Documents, the Agent shall in all cases be fully justified in failing or refusing to act hereunder and thereunder unless it shall receive further assurances to its satisfaction by the Banks of their indemnification obligations under SECTION 11.5 against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. 11.8 RESIGNATION OR REMOVAL OF THE AGENT. Subject to the appointment and acceptance of a successor Agent as provided below, the Agent may resign at any time by giving notice thereof to the Banks and the Company, and the Agent may be removed at any time with or without cause by the Required Banks. Upon any such resignation or removal, the Required Banks shall have the right to appoint a successor Agent. If no successor Agent shall have been so appointed by the Required Banks and shall have accepted such appointment within 30 days after the retiring Agent's giving of notice of resignation or the Required Banks' removal of the retiring Agent, then the retiring Agent may, on behalf of the Banks, appoint a successor Agent. Any successor Agent shall be a bank which has an office in the United States and a combined capital and surplus of at least $250,000,000 and with its deposits insured by the FDIC. Upon the acceptance of any appointment as the Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. Such successor Agent shall promptly specify its Principal Office referred to in SECTIONS 3.1 and 5.1 by notice to the Company. After any retiring Agent's resignation or removal hereunder as the Agent, the provisions of this SECTION 11 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Agent. Section 12. MISCELLANEOUS. 12.1 WAIVER. No waiver of any Default shall be a waiver of any other Default. No failure on the part of the Agent or any Bank to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege under any Credit Document shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege thereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The remedies provided in the -75- Credit Documents are cumulative and not exclusive of any remedies provided by law or in equity. 12.2 NOTICES. All notices and other communications provided for herein (including any modifications of, or waivers or consents under, this Agreement) shall be given or made by telex, telegraph, telecopy (confirmed by mail), cable or other writing and telexed, telecopied, telegraphed, cabled, mailed or delivered to the intended recipient at the "Address for Notices" specified below its name on the signature pages hereof; or, as to any party, at such other address as shall be designated by such party in a notice to the Company and the Agent given in accordance with this Section. Except as otherwise provided in this Agreement, all such communications shall be deemed to have been duly given when transmitted by telex or telecopier, delivered to the telegraph or cable office or personally delivered or, in the case of a mailed notice, upon receipt, in each case given or addressed as aforesaid. 12.3 EXPENSES, ETC. Whether or not any Letter of Credit is ever issued, the Company shall pay or reimburse on demand each of the Banks, the Agent and the Co-Agents for paying: (a) the reasonable fees and expenses of Liddell, Sapp, Zivley, Hill & LaBoon, L.L.P., special counsel to the Agent, in connection with (1) the preparation, execution and delivery of the Credit Documents (including the exhibits and schedules hereto), the issuance of the Letters of Credit hereunder and (2) any modification, supplement or waiver of any of the terms of any Credit Document; (b) all reasonable out-of-pocket costs and expenses of the Banks, the Agent and the Co-Agents (including costs of preparing an Independent Engineering Report and reasonable counsels' fees) in connection with any Event of Default under or the enforcement of any Credit Document; (c) all transfer, stamp, documentary or other similar taxes, assessments or charges levied by any governmental or revenue authority in respect of any Credit Document or any other document referred to therein; and (d) reasonable expenses of due diligence and syndication, and mutually agreed advertising and marketing costs. 12.4 INDEMNIFICATION. THE COMPANY SHALL INDEMNIFY THE AGENT (INCLUDING THE AGENT WHEN ACTING AS ISSUER OF THE LETTERS OF CREDIT), THE CO-AGENTS, THE BANKS, AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, AGENTS AND COUNSEL FROM, AND HOLD EACH OF THEM HARMLESS AGAINST, ANY AND ALL LOSSES, LIABILITIES, COSTS, EXPENSES, CLAIMS OR DAMAGES TO WHICH ANY OF THEM MAY BECOME SUBJECT, REGARDLESS OF AND INCLUDING LOSSES ARISING FROM THE NEGLIGENCE OF THE AGENT OR THE CO-AGENTS OR THE BANKS OR ANY OTHER INDEMNITEE, (A) IN CONNECTION WITH THE EXECUTION AND DELIVERY OR TRANSFER OF OR PAYMENT OR FAILURE TO PAY UNDER ANY LETTER OF CREDIT, INCLUDING, WITHOUT LIMITATION, ANY CLAIMS, DAMAGES, LOSSES, LIABILITIES, COSTS OR EXPENSES WHICH THE AGENT, SUCH CO-AGENT OR SUCH BANK, AS THE CASE MAY BE, MAY INCUR (WHETHER INCURRED AS A RESULT OF ITS OWN NEGLIGENCE OR OTHERWISE) BY REASON -76- OF OR IN CONNECTION WITH THE FAILURE OF ANY OTHER BANK (WHETHER AS A RESULT OF ITS OWN NEGLIGENCE OR OTHERWISE) TO FULFILL OR COMPLY WITH ITS OBLIGATIONS TO THE AGENT OR SUCH BANK, AS THE CASE MAY BE, HEREUNDER (BUT NOTHING HEREIN CONTAINED SHALL AFFECT THE RIGHTS THE COMPANY MAY HAVE AGAINST SUCH DEFAULTING BANK); AND (B) INSOFAR AS SUCH LOSSES, LIABILITIES, COSTS, EXPENSES, CLAIMS OR DAMAGES ARISE OUT OF OR RESULT FROM ANY (A) ACTUAL OR PROPOSED USE BY THE COMPANY OF THE PROCEEDS OF ANY EXTENSION OF CREDIT BY THE AGENT OR ANY BANK HEREUNDER; (B) BREACH BY THE COMPANY OF ANY CREDIT DOCUMENT (AS DEFINED HEREIN); (C) VIOLATION BY THE COMPANY OR ANY OF ITS SUBSIDIARIES OF ANY LEGAL REQUIREMENT INCLUDING APPLICABLE ENVIRONMENTAL LAWS; (D) ANY BANK'S OR THE AGENT'S OR ANY CO-AGENT'S BEING DEEMED AN OWNER OR OPERATOR OF ANY ASSETS OF THE COMPANY OR ITS SUBSIDIARIES BY A COURT OR OTHER REGULATORY OR ADMINISTRATIVE AGENCY OR TRIBUNAL IN CIRCUMSTANCES IN WHICH NEITHER THE AGENT, EITHER CO-AGENT NOR ANY OF THE BANKS IS GENERALLY OPERATING OR GENERALLY EXERCISING CONTROL OVER SUCH ASSETS, TO THE EXTENT SUCH LOSSES, LIABILITIES, CLAIMS OR DAMAGES ARISE OUT OF OR RESULT FROM ANY LEGAL REQUIREMENT INCLUDING APPLICABLE ENVIRONMENTAL LAWS PERTAINING TO THE CONDITION OF SUCH ASSETS, (E) ENVIRONMENTAL CLAIM OR (F) INVESTIGATION, LITIGATION OR OTHER PROCEEDING (INCLUDING ANY THREATENED INVESTIGATION OR PROCEEDING) RELATING TO ANY OF THE FOREGOING, and the Company shall reimburse the Agent, Co-Agent, each Bank, and each Affiliate thereof and their respective directors, officers, employees, agents and counsel, upon demand, for any expenses (including legal fees) incurred in connection with any such investigation or proceeding; but excluding any such losses, liabilities, claims, damages, costs or expenses incurred by a Person or any Affiliate thereof or their respective directors, officers, employees, agents or counsel by reason of the gross negligence or willful misconduct of such Person, Affiliate, director, officer, employee, agent or counsel. The obligation of the Company to provide indemnification under this SECTION 12.4 for fees and expenses of counsel shall be limited to the fees and expenses of one counsel in each jurisdiction representing all of the Persons entitled to such indemnification, except to the extent that, in the reasonable judgment of any such indemnified Person, the existence of actual or potential conflicts of interest make representation of all of such indemnified Persons by the same counsel inappropriate; in such a case, the Person exercising such judgment shall be indemnified for the reasonable fees and expenses of its separate counsel to the extent provided in this SECTION 12.4 without giving effect to the first clause of this sentence. Nothing in this SECTION 12.4 is intended to limit the obligations of the Company under any other provision of this Agreement. 12.5 AMENDMENTS, ETC. No amendment or waiver of any provision of any Credit Document, nor any consent to any departure by the Company therefrom, shall in any event be effective unless the same shall be agreed or consented to by the Required Banks and the Company, and each such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; -77- PROVIDED that no amendment, waiver or consent shall, unless in writing and signed by each Bank affected thereby, (a) increase the Commitment of any of the Banks or subject the Banks to any additional obligations; (b) reduce the principal of, or interest on, any Reimbursement Obligation, fee or other sum to be paid under any Credit Document; (c) postpone any scheduled date fixed for any payment of principal of, or interest on, any Reimbursement Obligation, fee or other sum to be paid under any Credit Document; (d) change the percentage of any of the Commitments, or of the aggregate unpaid principal amount of the Reimbursement Obligations, or the number of Banks which shall be required for the Banks or any of them to take any action under this Agreement; (e) change any provision contained in SECTIONS 2.3, 5.2, 5.7, 6, 12.3 or 12.4 or this SECTION 12.5, or in the definition of "Required Ratios". Anything in this SECTION 12.5 to the contrary, no amendment, waiver or consent shall be made with respect to SECTION 11 without the consent of the Agent and the Co-Agents. 12.6 SUCCESSORS AND ASSIGNS. (a) This Agreement shall be binding upon and inure to the benefit of the Company, the Agent, the Co-Agents and the Banks and their respective successors and assigns. The Company may not assign or transfer any of its rights or obligations hereunder without the prior written consent of all of the Banks. (b) Each Bank may sell participations to any Person in all or part of its Reimbursement Obligation, or all or part of its Commitment, in which event, without limiting the foregoing, the provisions of SECTION 6 shall inure to the benefit of each purchaser of a participation and the PRO RATA treatment of payments, as described in SECTION 5.2, shall be determined as if such Bank had not sold such participation. In the event any Bank shall sell any participation, (1) the Company, the Agent, the Co-Agent and the other Banks shall continue to deal solely and directly with such selling Bank in connection with such selling Bank's rights and obligations under the Credit Documents (including the Applications held by such selling Bank); (2) such Bank shall retain the sole right and responsibility to enforce the Reimbursement Obligations, including the right to approve any amendment, modification or waiver of any provision of this Agreement other than amendments, modifications or waivers with respect to (A) any fees payable hereunder to the Banks, and (B) the amount of principal or the rate of interest payable on, or the dates fixed for the scheduled repayment of principal of, the Reimbursement Obligations and other sums to be paid to the Banks hereunder, and (3) the Company agrees, to the fullest extent it may effectively do so under applicable law, that any participant of a Bank may exercise all rights of set-off, bankers' lien, counterclaim or similar rights with respect to such participation as fully as if such participant were a direct holder of Reimbursement Obligations if such Bank has previously given notice of such participation to the Company. -78- (c) Each Bank may assign to one or more Banks or Eligible Assignees all or a portion of its interests, rights and obligations under this Agreement (including all or a portion of its Commitment and the same portion of the related Reimbursement Obligations at the time owing to it); PROVIDED (1) other than in the case of an assignment to a Person at least 50% owned by the assignor Bank, or by a common parent of both, or to another Bank, the Agent and the Company must give their respective prior written consent, which consent will not be unreasonably withheld; (2) the aggregate amount of the Commitment and/or Reimbursement Obligations of the assigning Bank subject to each such assignment (determined as of the date the Assignment Agreement with respect to such assignment is delivered to the Agent) shall in no event be less than $750,000 (or $75,000 in the case of an assignment between Banks) (except for certain exceptions approved by the Company and the Agent) and shall be in an amount that is an integral multiple of $75,000; (3) the assigning Bank shall contemporaneously assign to such assignee Bank or Eligible Assignee an equal percentage of the assigning Bank's Facility B Commitment and Facility A Commitment (as that term is defined in the Amended and Restated Revolving Credit Agreement) and all of the assigning Bank's other rights and obligations under the Amended and Restated Revolving Credit Agreement; and (4) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance and recording in its records, an Assignment Agreement with blanks appropriately completed, together with the Applications subject to such assignment and a processing and recordation fee of $2,000 (for which the Company shall have no liability except in the case of assignments required by the Company pursuant to SECTION 6.1 or 6.2, in which case such fee shall be paid by the Company). Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment Agreement, (A) the assignee thereunder shall be a party hereto and, to the extent provided in such Assignment Agreement, have the rights and obligations of a Bank hereunder, and (B) the Bank making such assignment shall, to the extent provided in such assignment, be released from its obligations under this Agreement (and, in the case of an Assignment Agreement covering all or the remaining portion of an assigning Bank's rights and obligations under this Agreement, such Bank shall cease to be a party hereto). (d) By executing and delivering an Assignment Agreement, the Bank assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (1) other than the representation and warranty that it is the legal and beneficial owner of the interest being assigned thereby, such assignor Bank makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with any Credit Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of any Credit Document; (2) such assignor Bank makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Company or the -79- performance or observance by the Company of any of its obligations under any Credit Document; (3) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements of the Company previously delivered in accordance herewith and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment Agreement; (4) such assignee will, independently and without reliance upon the Agent, such assignor Bank or any other Bank and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Credit Documents; (5) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers under the Credit Documents as are delegated to the Agent by the terms hereof, together with such powers as are reasonably incidental thereto, and (6) such assignee agrees that it will perform in accordance with their terms all obligations that by the terms of the Credit Documents are required to be performed by it as a Bank. (e) The Agent shall maintain at its office a copy of each Assignment Agreement delivered to it and a record of the names and addresses of the Banks and the Commitment of, and principal amount of the Reimbursement Obligations owing to, each Bank from time to time. The entries in such record shall be conclusive, in the absence of manifest error, and the Company, the Agent and the Banks may treat each Person the name of which is recorded therein as a Bank hereunder for all purposes of the Credit Documents. Such records shall be available for inspection by the Company or any Bank at any reasonable time and from time to time upon reasonable prior notice. (f) Upon its receipt of an Assignment Agreement executed by an assigning Bank and the assignee thereunder together with the Application subject to such assignment, the written consent to such assignment and the fee payable in respect thereto, the Agent shall, if such Assignment Agreement has been completed with blanks appropriately filled, (1) accept such Assignment Agreement; (2) record the information contained therein in its records, and (3) give prompt notice thereof to the Company. (g) Any Bank may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section, disclose to the assignee or participant or proposed assignee or participant, any information relating to the Company furnished to such Bank by or on behalf of the Company. (h) Any assignment by a Bank pursuant to this SECTION 12.6 shall not result in any single Bank holding in excess of 25% of the Aggregate Commitment at any one time. -80- (i) Notwithstanding any other provision of this SECTION 12.6, TCB and its Affiliates may not assign their rights hereunder unless, after giving effect to such assignment, TCB and its Affiliates would have an aggregate Commitment Percentage of at least 10%. (j) Notwithstanding anything herein to the contrary, each Bank may pledge and assign all or any portion of its rights and interests under the Credit Documents to any Federal Reserve Bank. 12.7 SURVIVAL; TERM; REINSTATEMENT. In addition to the other provisions of this Agreement expressly stated to survive the termination of this Agreement, the obligations of the Company under SECTIONS 6, 12.3 and 12.4 and the last sentence of this SECTION 12.7 and the obligations of the Banks under SECTION 12.8 shall survive the termination of this Agreement. The term of this Agreement shall be until (a) the full and final payment of all Reimbursement Obligations, (b) the expiry of all Letters of Credit, (c) the termination of all Commitments and (d) the payment of all amounts due under the Credit Documents. The Company agrees that if at any time all or any part of any payment previously applied by any Bank to any Reimbursement Obligation or other sum hereunder is or must be returned by or recovered from such Bank for any reason (including the order of any bankruptcy court), the Credit Documents shall automatically be reinstated to the same effect as if the prior application had not been made, and the Company hereby agrees to indemnify such Bank against, and to save and hold such Bank harmless from, any required return by or recovery from such Bank of any such payment because of its being deemed preferential under applicable Legal Requirements, or for any other reason. 12.8 LIMITATION OF INTEREST. The parties to this Agreement intend to strictly comply with all applicable laws, including applicable usury laws. Accordingly, the provisions of this Section shall govern and control over every other provision of any Credit Document which conflicts or is inconsistent with this Section, even if such provision declares that it controls. As used in this SECTION 12.8, the term "interest" includes the aggregate of all charges, fees, benefits or other compensation which constitute interest under applicable law; PROVIDED that, to the maximum extent permitted by applicable law, (a) any non-principal payment shall be characterized as an expense or as compensation for something other than the use, forbearance or detention of money, and not as interest and (b) all interest at any time contracted for, taken, reserved, retained, charged or received shall be amortized, prorated, allocated and spread, in equal parts during the full term of this Agreement and the Commitments. In no event shall the Company or any other Person be obligated to pay, or the Agent or any Bank have any right or privilege to reserve, receive or retain, (x) any interest in excess of the maximum amount of nonusurious interest permitted under the laws of the State of Texas or the applicable laws (if any) of the United States or of any other state -81- or (y) total interest in excess of the amount which the Agent or such Bank could lawfully have contracted for, taken, reserved, received, retained or charged had the interest been calculated for the full term of this Agreement at the Highest Lawful Rate. On each day, if any, that the interest rate (the "STATED RATE") called for under any Credit Document exceeds the Highest Lawful Rate, the rate at which interest shall accrue shall automatically be fixed by operation of this sentence at the Highest Lawful Rate for that day, and shall remain fixed at the Highest Lawful Rate for each day thereafter until the total amount of interest accrued equals the total amount of interest which would have accrued if there were no such ceiling rate as is imposed by this sentence. Thereafter, interest shall accrue at the Stated Rate unless and until the Stated Rate again exceeds the Highest Lawful Rate when the provisions of the immediately preceding sentence shall again automatically operate to limit the interest accrual rate. The daily interest rates to be used in calculating interest at the Highest Lawful Rate shall be determined by dividing the applicable Highest Lawful Rate per annum by the number of days in the calendar year for which such calculation is being made. None of the terms and provisions contained in any Credit Document which directly or indirectly relate to interest shall ever be construed without reference to this Section, or be construed to create a contract to pay for the use, forbearance or detention of money at an interest rate in excess of the Highest Lawful Rate. If the term of this Agreement is shortened by reason of acceleration of maturity as a result of any Default or by any other cause, or by reason of any required or permitted prepayment, and if for that (or any other) reason the Agent or any Bank at any time, including the stated maturity, is owed or receives (and/or has received) interest in excess of interest calculated at the Highest Lawful Rate, then and in any such event all of any such excess interest shall be canceled automatically as of the date of such acceleration, prepayment or other event which produces the excess, and, if such excess interest has been paid to the Agent or such Bank, it shall be credited PRO TANTO against the then-outstanding principal balance of the Company's obligations to the Agent or such Bank, effective as of the date or dates when the event occurs which causes it to be excess interest, until such excess is exhausted or all of such principal has been fully paid and satisfied, whichever occurs first, and any remaining balance of such excess shall be promptly refunded to its payor. 12.9 CAPTIONS. Captions and section headings appearing herein are included solely for convenience of reference and are not intended to affect the interpretation of any provision of this Agreement. 12.10 COUNTERPARTS. Each Credit Document may be executed in any number of counterparts, all of which taken together shall constitute one and the same agreement and any of the parties hereto may execute such Credit Document by signing any such counterpart. -82- 12.11 GOVERNING LAW. EXCEPT TO THE EXTENT OTHERWISE SPECIFIED THEREIN, EACH CREDIT DOCUMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF TEXAS AND THE UNITED STATES OF AMERICA. THE COMPANY HEREBY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF TEXAS AND OF ANY TEXAS STATE COURT SITTING IN HARRIS COUNTY, TEXAS FOR PURPOSES OF ALL LEGAL PROCEEDINGS ARISING OUT OF OR RELATING TO THE CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY. THE COMPANY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. 12.12 SEVERABILITY. Whenever possible, each provision of the Credit Documents shall be interpreted in such manner as to be effective and valid under applicable law. If any provision of any Credit Document shall be invalid, illegal or unenforceable in any respect under any applicable law, the validity, legality and enforceability of the remaining provisions of such Credit Document shall not be affected or impaired thereby. 12.13 CHAPTER 15 NOT APPLICABLE. Chapter 15 of the Texas Credit Code shall not apply to any Credit Document or to any Commitment or Letter of Credit or Application or Reimbursement Obligation, nor shall any Credit Document be governed by or be subject to the provisions of such Chapter 15 in any manner whatsoever. -83- IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed and delivered effective as of the day and year first above written.
