From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and premium as aforesaid, interest on such principal amount shall cease to accrue.

Notice of each exercise of such right by any Purchaser, specifying the date on which such repurchase will occur, will be given to the Company within 90 days after such Change of Control and at least 30 days but not more than 60 days before such repurchase date. In the case of each repurchase of Notes pursuant to this Section 7.4, the foregoing purchase price for the Notes to be repurchased shall be due and payable on the date fixed for such repurchase, together with all accrued and unpaid interest on such Notes. From and after such date, unless the Company shall fail to pay such repurchase price when so due and payable, together with interest as aforesaid, interest on such Notes shall cease to accrue.

As used herein, "QIB" means a "qualified institutional buyer" as defined in Rule 144A under the Securities Act. (b) Each Purchaser agrees that it will not solicit offers for, offer, or sell the Notes by any form of general solicitation or general advertising (as those terms are used in Regulation D 33 under the Securities Act) or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act. (c) Notwithstanding the foregoing provisions of this Article XI, TCW may transfer Notes to its investors as required by the terms of its agreements with and obligations to its investors in the event of any distribution of its assets to investors that are withdrawing from their investment relationships with TCW. ARTICLE XII. COLLATERAL AGENT. Section XII.1. Appointment and Authority. Each Purchaser hereby appoints ------------------------- Tamco as collateral agent (herein, together with its successors and assigns in such capacity, "Collateral Agent") under the Transaction Documents, to exercise such powers under the Transaction Documents as are delegated to Collateral Agent by the terms thereof, together with all such powers as are reasonably incidental thereto, including taking, holding and disposing of the Collateral. Tamco hereby accepts such appointment. Collateral Agent shall act for and on behalf of the Purchasers in connection with all Collateral and all Security Documents, including serving as mortgagee under each Mortgage and exercising rights and remedies provided thereunder. Each Mortgage, as well as the Bank Subordination Agreement, contemplates that Collateral Agent may release Collateral in accordance with the terms thereof and Collateral Agent is hereby authorized to do so as required thereunder or hereunder or if Collateral Agent has otherwise received the prior consent of Majority Purchasers, it being understood that no Purchaser itself need be a party to any such release. In its administration of this Agreement and the other Transaction Documents, Collateral Agent will exercise the same care that a commercial bank would exercise in the administration or handling of transactions for its own account. The relationship of Collateral Agent to the Purchasers is only that of one investor acting to hold collateral on behalf of itself and others as a convenience to all, and nothing in the Transaction Documents shall be construed to constitute Collateral Agent a trustee or other fiduciary for any holder of any of the Notes or of any participation therein nor to impose on Collateral Agent any duties and obligations other than those expressly provided for in the Transaction Documents. With respect to any matters not expressly provided for in the Transaction Documents and any matters which the Transaction Documents place within the discretion of Collateral Agent, Collateral Agent shall not be required to exercise any discretion or take any action, and it may request instructions from the Purchasers with respect to any such matter, in which case it shall be required to act or to refrain from acting (and shall be fully protected and free from liability to all Purchasers in so acting or refraining from acting) upon the instructions of Majority Purchasers, provided, however, that Collateral Agent shall not be required to take any action which exposes it to a risk of personal liability that it considers unreasonable or which is contrary to the Transaction Documents or to applicable law. Each Purchaser hereby authorizes Collateral Agent to execute an Intercreditor Agreement with the Agent Bank and Mariner and First Amendment to Intercreditor Agreement with the Agent Bank and MAG. Section XII.2. Exculpation, Collateral Agent's Reliance, Etc. Neither --------------------------------------------- Collateral Agent nor any of its directors, officers, agents, attorneys, or employees shall be liable for any action 34 taken or omitted to be taken by any of them under or in connection with the Transaction Documents, INCLUDING THEIR NEGLIGENCE OF ANY KIND, except that each shall be liable for its own gross negligence or willful misconduct. Without limiting the generality of the foregoing, Collateral Agent (a) may treat the registered holder of any Note as the holder thereof until Collateral Agent receives written notice of the assignment or transfer thereof in accordance with this Agreement; (b) may consult with legal counsel (including counsel for the Company), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Purchaser and shall not be responsible to any Purchaser for any statements, warranties or representations made in or in connection with the Transaction Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of the Transaction Documents on the part of the Company or any Subsidiary of the Company or to inspect the property (including the books and records) of the Company or any Subsidiary of the Company or to forward notices to the Purchasers on behalf of the Company or any of its Subsidiaries; (e) shall not be responsible to any Purchaser for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of any Transaction Document or any instrument or document furnished in connection therewith; (f) may rely upon the representations and warranties of each of the Company and each Subsidiary of the Company and the Purchasers in exercising its powers hereunder; and (g) shall incur no liability under or in respect of the Transaction Documents by acting upon any notice, consent, certificate or other instrument or writing (including any telecopy, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper Person or Persons. Section XII.3. Credit Decisions. Each Purchaser acknowledges that it has, ---------------- independently and without reliance upon any other Purchaser or Collateral Agent, made its own analysis of the Company and the transactions contemplated hereby and its own independent decision to enter into this Agreement and the other Transaction Documents. Each Purchaser also acknowledges that it will, independently and without reliance upon any other Purchaser or Collateral Agent 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 Transaction Documents. Section XII.4. Indemnification. Each Purchaser agrees to indemnify --------------- Collateral Agent (to the extent not reimbursed by the Company within ten (10) days after demand) from and against such Purchaser's Percentage Share of any and all liabilities, obligations, claims, losses, damages, penalties, fines, actions, judgments, suits, settlements, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this Section collectively called "liabilities and costs") which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against Collateral Agent growing out of, resulting from or in any other way associated with any of the Collateral, the Transaction Documents and the transactions and events (including the enforcement thereof) at any time associated therewith or contemplated therein (including any violation or noncompliance with any Environmental laws by any Person or any liabilities or duties of any Person with respect to Hazardous Materials found in or released into the environment). 35 The foregoing indemnification shall apply whether or not such liabilities and costs are in any way or to any extent owed, in whole or in part, under any claim or theory of strict liability, or are caused, in whole or in part, by any negligent act or omission of any kind by Collateral Agent, provided only that no Purchaser shall be obligated under this Section to indemnify Collateral Agent for that portion, if any, of any liabilities and costs which is proximately caused by Collateral Agent's own individual gross negligence or willful misconduct, as determined in a final judgment. Cumulative of the foregoing, each Purchaser agrees to reimburse Collateral Agent promptly upon demand for such Purchaser's Percentage Share of any costs and expenses to be paid to Collateral Agent by the Company under Section 8.1(i) to the extent that Collateral Agent is not timely reimbursed for such expenses by the Company as provided in such section. As used in this Section the term "Collateral Agent" shall refer not only to the Person designated as such in Section 12.1 but also to each director, officer, agent, attorney, employee, representative and Affiliate of such Person. Section XII.5. Rights as Purchaser. In its capacity as a Purchaser, ------------------- Collateral Agent and each Affiliate of Collateral Agent shall have the same rights and obligations as any Purchaser and may exercise such rights as though it were not Collateral Agent or an Affiliate of Collateral Agent. Collateral Agent and its Affiliates may generally engage in any kind of business with the Company or any Subsidiary or Affiliate of the Company, all as if it were not Collateral Agent hereunder and without any duty to account therefor to any Purchaser. Section XII.6. Sharing of Set-Offs, Collections, and Payments. ---------------------------------------------- (a) Each Purchaser agrees that if it shall, whether through the exercise of rights under Security Documents or rights of banker's lien, set off, or counterclaim against the Company or otherwise, obtain payment of a portion of the aggregate Obligations owed to it which, taking into account all distributions made by Collateral Agent under this Agreement, causes such Purchaser to have received more than it would have received had such payment been made pro rata to each Purchaser in accordance with the following subsection (b), then (i) it shall be deemed to have simultaneously purchased and shall be obligated to purchase interests in the Obligations as necessary to cause all Purchasers to share all payments as if such payments had been made pro rata to each Purchaser in accordance with the following subsection (b), and (ii) such other adjustments shall be made from time to time as shall be equitable to ensure that Collateral Agent and all Purchasers share all payments of Obligations as if such payments had been made pro rata to each Purchaser in accordance with the following subsection (b); provided, however, that nothing herein contained shall in any way affect the right of any Purchaser to obtain payment (whether by exercise of rights of banker's lien, set-off or counterclaim or otherwise) of Liabilities other than the Obligations. The Company expressly consents to the foregoing arrangements and agrees that any holder of any such interest or other participation in the Obligations, whether or not acquired pursuant to the foregoing arrangements, may to the fullest extent permitted by law exercise any and all rights of banker's lien, set-off, or counterclaim as fully as if such holder were a holder of the Obligations in the amount of such interest or other participation. If all or any part 36 of any funds transferred pursuant to this Section is thereafter recovered from the seller under this Section which received the same, the purchase provided for in this Section shall be deemed to have been rescinded to the extent of such recovery, together with interest, if any, if interest is required pursuant to an order of a Governmental Authority to be paid on account of the possession of such funds prior to such recovery. (b) If Collateral Agent collects or receives money on account of the Collateral, Collateral Agent shall distribute all money so collected or received as follows: (i) first, for the payment of all amounts owing to Collateral Agent under Section 8.1(i) or Section 13.5 of this Agreement or any similar provisions of other Transaction Documents; and (ii) then to each Purchaser in accordance with such Purchaser's Percentage Share. Section XII.7. Investments. Whenever Collateral Agent in good faith ----------- determines that it is uncertain about how to distribute to Purchasers any funds which it has received, or whenever Collateral Agent in good faith determines that there is any dispute among Purchasers about how such funds should be distributed, Collateral Agent may choose to defer distribution of the funds which are the subject of such uncertainty or dispute. If Collateral Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if Collateral Agent is otherwise required to invest funds pending distribution to Purchasers, Collateral Agent shall invest such funds pending distribution in one or more separate accounts not commingled with other assets of the Collateral Agent; all interest on any such investment shall be distributed upon the distribution of such investment and in the same proportion and to the same Persons as such investment. All moneys received by Collateral Agent for distribution to Purchasers (other than to a Person who is Collateral Agent in its separate capacity as a Purchaser) shall be held by Collateral Agent pending such distribution solely as Collateral Agent for such Purchasers, and Collateral Agent shall have no equitable title to any portion thereof. Section XII.8. Benefit of Article XII. The provisions of this Article are ---------------------- intended solely for the benefit of Purchasers and Collateral Agent, and neither the Company nor any Subsidiary of the Company shall be entitled to rely on any such provision or assert any such provision in a claim or defense against any Purchaser or Collateral Agent. Purchasers and Collateral Agent may waive or amend such provisions as they desire without any notice to or consent of the Company or any Subsidiary of the Company. Section XII.9. Resignation. Collateral Agent may resign at any time by ----------- giving written notice thereof to the Purchasers and the Company. Each such notice shall set forth the date of such resignation. Upon any such resignation the Majority Purchasers shall designate a successor Collateral Agent. A successor must be appointed for any retiring Collateral Agent, and such Collateral Agent's resignation shall become effective when such successor accepts such appointment. If, within thirty days after the date of the retiring Collateral Agent's resignation, no successor Collateral Agent has been appointed and has accepted such appointment, then the retiring Collateral Agent may appoint a successor Collateral Agent. Upon the acceptance of any 37 appointment as Collateral Agent hereunder by a successor Collateral Agent, the retiring Collateral Agent shall be discharged from its duties and obligations under this Agreement and the other Transaction Documents. After any retiring Collateral Agent's resignation hereunder the provisions of this Article XII and Section 13.5 shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was Collateral Agent under the Transaction Documents. The Company hereby agrees to pay all fees, if any, as may be charged by any successor Collateral Agent that is a national or state bank or trust company which such Person may reasonably charge for its services as Collateral Agent, and to enter into or consent to such documents and instruments as such successor Collateral Agent may request in connection with its service and appointment as Collateral Agent. ARTICLE XIII. MISCELLANEOUS. Section XIII.1. Place of Payment. Subject to Section 13.2, payments of ---------------- principal, premium and repurchase price, if any, and interest becoming due and payable on the Notes shall be made in Dallas, Dallas County, Texas at the principal office of Bank of America, N.A., in such jurisdiction (presently 901 Main Street, Dallas, Texas 75202). The Company may at any time, by notice to each holder of a Note, change the place of payment of the Notes so long as such place of payment shall be either the principal office of the Company in Tarrant or Dallas Counties, Texas, or the principal office of a bank or trust company in either of such jurisdictions. Section XIII.2. Home Office Payment. So long as any Purchaser originally ------------------- party hereto, or any nominee of such Purchaser, shall be the holder of any Note, and notwithstanding anything contained in Section 13.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, premium or repurchase price, if any, and interest by the method and at the address specified for such purpose below such Purchaser's name in Schedule A, or by such other method or at such other address as such Purchaser shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to Section 13.1. Prior to any sale or other dispo sition of any Note held by such Purchaser or such Purchaser's nominee, such Purchaser will, at such Purchaser's election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to Section 11.2. The Company will afford the benefits of this Section to any Institutional Investor that is the direct or indirect transferee of any Note purchased by such Purchaser under this Agreement and that has made the same agreement relating to such Note as such Purchaser has made in this Section. Section XIII.3. Waivers and Amendments; Acknowledgments. --------------------------------------- 38 (a) Waivers and Amendments. No failure or delay (whether by course of ---------------------- conduct or otherwise) by Purchasers or Collateral Agent in exercising any right, power or remedy which any of them may have under any of the Transaction Documents shall operate as a waiver thereof or of any other right, power or remedy, nor shall any single or partial exercise by Purchasers or Collateral Agent of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy. No waiver, consent, release, modification or amendment of or supplement to this Agreement or the other Transaction Documents shall be valid or effective against any party hereto unless the same is in writing and signed by (a) if such party is the Company, by the Company, (b) if such party is Collateral Agent, by Collateral Agent, and (c) if such party is a Purchaser, by Majority Purchasers or, in connection with any Collateral or Security Document, by Collateral Agent on behalf of Purchasers with the written consent of Majority Purchasers (which consent has already been given with respect to certain releases as provided in Section 12.1 and with respect to the termination of the Transaction Documents as provided in Section 13.10). Notwithstanding the foregoing or anything to the contrary herein, (i) no amendment or waiver of any of the provisions of Sections 1.1, 2.1, 2.2, 4.1, 4.2, 6.1, and 6.2 hereof, or any defined term (as it is used therein), will be effective as to any Purchaser unless consented to by such Purchaser, and (ii) no such amendment or waiver may, without the written consent of the holder of each Note at the time outstanding affected thereby, (1) subject to the provisions of Sections 10.1, 10.2, and 10.3 relating to acceleration or rescission, change the amount or time of any prepayment or payment of principal of, or reduce the rate or change the time of payment or method of computation of interest on the Notes, (2) change the percentage of the principal amount of the Notes the holders of which are required to consent to any such amendment or waiver, or (3) amend any of Sections 7.1, 7.2, 7.3, 7.4, 7.5, and this Section 13.3(a). Any amendment or waiver consented to as provided in this subsection applies equally to all Purchasers and is binding upon them and upon each future Purchaser and upon the Company without regard to whether such Note has been marked to indicate such amendment or waiver. (b) Solicitation. The Company will provide each Purchaser (irrespective ------------ of the amount of Notes then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such Purchaser to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the pro visions hereof or of the Transaction Documents. The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 13.3 to each Purchaser promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite Purchasers. (c) Payment. The Company will not directly or indirectly pay or cause to ------- be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security, to any Purchaser as consideration for or as an inducement to the entering into by any Purchaser or any waiver or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted, on the same terms, ratably to or for the benefit of each Purchaser then outstanding even if such Purchaser did not consent to such waiver or amendment. 39 (d) Acknowledgments and Admissions. The Company represents, warrants, ------------------------------ acknowledges and admits that (i) it has been advised by counsel in the negotiation, execution and delivery of the Transaction Documents to which it is a party, (ii) it has made an independent decision to enter into this Agreement and the other Transaction Documents to which it is a party, without reliance on any representation, warranty, covenant or undertaking by Purchasers or Collateral Agent whether written, oral or implicit, other than as expressly set out in this Agreement or in another Transaction Document delivered on or after the date hereof, (iii) there are no representations, warranties, covenants, undertakings or agreements by Purchasers or Collateral Agent as to the Transaction Documents except as expressly set out in this Agreement or in another Transaction Document delivered on or after the date hereof, (iv) neither Purchasers nor Collateral Agent owes any fiduciary duty to the Company with respect to any Transaction Document or the transactions contemplated thereby, (v) the relationship pursuant to the Transaction Documents between the Company, on one hand, and Purchasers and Collateral Agent, on the other hand, is and shall be solely that of debtor and creditor, respectively, (vi) no partnership or joint venture exists with respect to the Transaction Documents between the Company and any of the Purchasers or Collateral Agent, (vii) should an Event of Default or Default occur or exist each Purchaser and Collateral Agent will determine in its sole and absolute discretion and for its own reasons what remedies and actions it will or will not exercise or take at that time, (viii) without limiting any of the foregoing, the Company is not relying upon any representation or covenant by any Purchaser or Collateral Agent, or any representative thereof, and no such representation or covenant has been made, that Purchasers or Collateral Agent at the time of an Event of Default or Default, or at any other time, waive, negotiate, discuss, or take or refrain from taking any action permitted under the Transaction Documents with respect to any such Event of Default or Default or any other provision of the Transaction Documents, and (ix) each Purchaser has relied upon the truthfulness of the acknowledgments in this Section in deciding to execute and deliver this Agreement and to purchase the Notes. This written agreement and the other Transaction Documents represent the final agreement between the parties and may not be contradicted by evidence of prior, contemporaneous, or subsequent oral agreements of the parties. There are no unwritten oral agreements between the parties. Section XIII.4. Survival of Agreements; Cumulative Nature. All of the ----------------------------------------- various representations, warranties, covenants and agreements in the Transaction Documents shall survive the execution and delivery of this Agreement and the other Transaction Documents and the performance hereof and thereof, including the sale, purchase, and delivery of the Notes and the other Transaction Documents, and shall further survive until all of the Obligations are paid in full to Purchasers and Collateral Agent. All statements and agreements contained in any certificate or other instrument delivered by the Company to Purchasers or Collateral Agent under any Transaction Document shall be deemed representations and warranties by the Company or 40 agreements and covenants of the Company under this Agreement. The representations, warranties, and covenants made by the Company in the Transaction Documents, and the rights, powers, and privileges granted to Purchasers and Collateral Agent in the Transaction Documents, are cumulative, and, except for expressly specified waivers and consents, no Transaction Document shall be construed in the context of another to diminish, nullify, or otherwise reduce the benefit to Purchasers or Collateral Agent of any such representation, warranty, covenant, right, power or privilege. In particular and without limitation, no exception set out in this Agreement to any representation, warranty or covenant herein contained shall apply to any similar representation, warranty or covenant contained in any other Transaction Document, and each such similar representation, warranty or covenant shall be subject only to those exceptions which are expressly made applicable to it by the terms of the various Transaction Documents. Section XIII.5. Indemnity. The Company agrees to indemnify each Purchaser ---------- Entity, upon demand, from and against any and all liabilities, obligations, claims, losses, damages, penalties, fines, actions, judgments, suits, settlements, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this Section collectively called "liabilities and costs") which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against such Purchaser Entity growing out of, resulting from or in any other way associated with any of the Collateral, the Transaction Documents, or the transactions and events (including the enforcement or defense thereof) at any time associated therewith or contemplated therein (including any violation or noncompliance with any Environmental Laws by the Company or any liabilities or duties of the Company or of any Purchaser Entity with respect to Hazardous Materials found in or released into the environment). The foregoing indemnification shall apply whether or not such liabilities and costs are in any way or to any way or to any extent owed, in whole or in part, under any claim or theory of strict liability or are in any extent caused, in whole or in part, by any negligent act or omission of any kind by any Purchaser Entity, provided only that no Purchaser Entity shall be entitled under this Section to receive indemnification for that portion, if any, of any liabilities and costs which is proximately caused by its own individual gross negligence or willful misconduct, as determined in a final judgment, or by its own individual actions with respect to Collateral in its possession. As used in this Section the term "Purchaser Entity" refers to each Purchaser, to Collateral Agent, and to each director, officer, agent, trustee, manager, attorney, employee, representative and Affiliate of any such Person. Section XIII.6. Notices. All notices, requests, consents, demands and other ------- communications required or permitted under any Transaction Document shall be in writing, unless otherwise specifically provided in such Transaction Document, and shall be deemed sufficiently given or furnished if delivered by personal delivery, by telecopy, by delivery service 41 with proof of delivery, or by registered or certified United States mail, postage prepaid, to each party hereto at the address of such party specified on the signature pages hereto (unless changed by similar notice in writing given by the particular Person whose address is to be changed). Any such notice or communication shall be deemed to have been given (a) in the case of personal delivery or delivery service, as of the date of first attempted delivery during normal business hours at the address and in the manner provided herein, (b) in the case of telecopy, upon receipt, or (c) in the case of registered or certified United States mail, three days after deposit in the mail. Section XIII.7. Parties in Interest. All grants, covenants and agreements ------------------- contained in the Transaction Documents shall bind and inure to the benefit of the parties thereto and their respective successors and assigns; provided, however, that the Company may not assign or transfer any of its rights or delegate any of its duties or obligations under any Transaction Document without the prior consent of Purchasers as required under Section 13.3. Section XIII.8. Governing Law; Submission to Process. Except to the extent ------------------------------------ that the law of another jurisdiction is expressly elected in a transaction document, the Transaction Documents shall be construed and enforced in accordance with and governed by the laws of the State of Texas and of the United States of America (without regard to Texas principles of conflicts of law) with respect to all other matters. The Company hereby irrevocably submits itself to the non-exclusive jurisdiction of the state and federal courts sitting in the State of Texas and the County of Dallas, and the Company agrees and consents that service of process may be made upon it in any legal proceeding relating to the Transaction Documents or the Obligations by any means allowed under Texas or federal law. The Company irrevocably waives, to the fullest extent permitted by applicable law, any objection that it may now or hereafter have to the laying of the venue of any such proceeding brought in any such court and any claim that any such proceeding brought in any such court has been brought in an inconvenient forum. 42 Section XIII.9. Limitation on Interest. Purchasers, Collateral ---------------------- Agent, the Company and any other parties to the Transaction Documents intend to contract in strict compliance with applicable usury law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Transaction Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be charged by applicable law from time to time in effect. Neither the Company nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum amount that may be lawfully charged under applicable law from time to time in effect, and the provisions of this Section shall control over all other provisions of the Transaction Documents which may be in conflict or apparent conflict herewith. Purchasers and Collateral Agent expressly disavow any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of any Obligation is accelerated. If (a) the maturity of any Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) any Purchaser or any other holder of any or all of the Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted to be charged by applicable law then in effect, then all such sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, at such Purchaser's or such holder's option, promptly returned to the Company or the other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific circumstance, exceeds the maximum amount permitted under applicable law, Purchasers, Collateral Agent and the Company (and any other payors or payees thereof) shall to the greatest extent permitted under applicable law, (i) characterize any non-principal payment as an expense, fee or premium rather than as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Notes in accordance with the amounts outstanding from time to time thereunder and the maximum legal rate of interest from time to time in effect under applicable law in order to lawfully charge the maximum amount of interest permitted under applicable law. Section XIII.10. Termination; Limited Survival. In its sole and ----------------------------- absolute discretion the Company may at any time after all Obligations have been paid in full elect in a notice delivered to all Purchasers to terminate this Agreement and the other Transaction Documents. Upon receipt by Purchasers of such a notice, if no Obligations are then owing then this Agreement and all other Transaction Documents shall thereupon be terminated, the Liens thereunder released, and the parties thereto released from all prospective obligations thereunder. Notwithstanding the foregoing or anything herein to the contrary, any waivers or admissions made by the Company in any Transaction Document, and any other obligations which any Person may have to indemnify or compensate Collateral Agent, any Purchaser or any or their respective Affiliates or related Persons shall survive any termination of this Agreement or any other Transaction Document. At the request and expense of the Company, Purchasers and 43 Collateral Agent shall prepare and execute all necessary instruments to reflect and effect such termination of the Transaction Documents. Section XIII.11. Reproduction of Documents. This Agreement and all ------------------------- documents relating thereto, including, without limitation, (a) consents, waivers and modifications that may hereafter be executed, (b) documents received by Collateral Agent or any Purchaser at the Closing (except the Notes themselves), and (c) financial statements, certificates and other information previously or hereafter furnished to Collateral Agent or such Purchaser, may be reproduced by Collateral Agent or such Purchaser by any photographic, photostatic, microfilm, microcard, miniature photographic or other similar process and Collateral Agent or such Purchaser may destroy any original document so reproduced. The Company agrees and stipulates that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by Collateral Agent or such Purchaser in the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section shall not prohibit the Company or Collateral Agent or any Purchaser from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction. Section XIII.12. Confidentiality. For the purposes of this Section, --------------- "Confidential Information" means information delivered to any Purchaser by or on behalf of the Company or any Subsidiary of the Company in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by such Purchaser as being confidential infor mation of the Company or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any Person acting on such Purchaser's behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or any Subsidiary or (d) constitutes financial statements delivered to such Purchaser hereunder that are otherwise publicly available. Such Purchaser will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to (i) such Purchaser's directors, officers, employees, agents, attorneys, investors, and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by such Purchaser's Notes), (ii) such Purchaser's Affiliates, auditors, attorneys, and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section, (iii) any other Purchaser, (iv) any Institutional Investor to which such Purchaser may sell or offer to sell such Note or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section), (v) any Person from which such Purchaser may offer to purchase any security of the Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section), (vi) any federal or state regulatory authority having jurisdiction over such Purchaser, (vii) the National Association of Insurance Commissioners or any similar 44 organization, or any nationally recognized rating agency that requires access to information about such Purchaser's investment portfolio or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate (1) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (2) in response to any subpoena or other legal process, (3) in connection with any litigation to which such Purchaser is a party or (4) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under such Purchaser's Notes and this Agreement.
