SECTION 2. FUNDING LOANS, PAYMENTS, RECOVERIES AND COLLECTIONS

2.1 Funding Loans. Subject to the terms, conditions and procedures of this Agreement and each other Loan Document and to the satisfaction of all conditions precedent to the making and funding of any loan as set forth in any Loan Document, Bank shall make the proceeds of any such loan available to Borrower on the disbursement date agreed upon by Bank and Borrower by depositing such proceeds into an account maintained by Borrower with Bank or as otherwise agreed to in writing by Borrower and Bank.

2.2 Revolving Loans. Subject to the terms and conditions of the Loan Documents and to the satisfaction of all conditions precedent to the making and funding of any loan as set forth in any Loan Document, the

Bank agrees to make Revolving Loans to Borrower at any time and from time to time from the effective date hereof until (but not including) the Revolving Credit Maturity Date. The proceeds of Revolving Loans shall be used solely to refinance certain indebtedness to Tejas Energy NS, LLC existing at the time of initial funding hereunder and thereafter for working capital needs of Borrower.

Borrower may request a Revolving Loan pursuant to terms of the Revolving Credit Note and (a) such request for advance once communicated to Bank, shall not be revocable by Borrower; and (b) each request for advance, once communicated to Bank, shall constitute a representation, warranty and certification by Borrower as of the date thereof that, (i) the making of such Revolving Loan will not cause the aggregate outstanding principal amount of all Revolving Loans to exceed the Revolving Credit Maximum Amount; (ii) no Default or Event of Default shall have occurred and be in existence, and none will exist or arise upon the making of such Revolving Loan; and (iii) the representations and warranties contained in the Loan Documents are true and correct in all material respects and shall be true and correct in all material respects as of the making of such Revolving Loan.

Bank may elect (but without any obligation to do so) to make a Revolving Loan upon the telephonic or facsimile request of Borrower, provided that Borrower has first executed and delivered to Bank a telephone notice authorization in form and content satisfactory to Bank. If any such Revolving Loan based upon a telephonic or facsimile request is made by Borrower, Bank may require Borrower to confirm said telephonic or facsimile request in writing by delivering to Bank, on or before 12:00 noon (Dallas, Texas time) on the next business day following the disbursement date of such Revolving Loan, a duly executed written request for advance, and all other provisions of this Section 2.2 shall be applicable with respect to such Revolving Loan.

Notwithstanding anything contained in this Agreement to the contrary, the aggregate principal amount of all Revolving Loans shall not exceed the Revolving Credit Maximum Amount. If said limitations are exceeded at anytime, Borrower shall immediately, without demand by Bank, pay to Bank an amount not less than such excess, or, if Bank, in its sole discretion, shall so agree, Borrower shall provide Bank cash collateral in an amount not less than such excess, and Borrower hereby pledges and grants to Bank a security interest in such cash collateral so provided to Bank. Unless otherwise expressly provided in a Loan Document, all sums payable by Borrower to Bank under or pursuant to any Loan Document, whether principal, interest, or otherwise, shall be paid, when due, directly to Bank at any office of Bank located in the State of Texas in immediately available United States funds, and without setoff, deduction or counterclaim. Upon the occurrence during the continuance of any Event of Default pursuant to Section 6.1(a) or the acceleration of the Revolving Loans, Bank may, in its discretion, charge any and all deposit or other accounts (including, without limitation, any account evidenced by a certificate of deposit or time deposit) of Borrower maintained with Bank for all or any part of any Indebtedness then due and payable; provided, however, that such authorization shall not affect Borrower's obligations to pay all Indebtedness, when due, whether or not any such account balances maintained by Borrower with Bank are insufficient to pay any amounts then due.

Borrower shall pay to Bank a commitment fee on the undrawn portion of the Revolving Credit Note in an amount equal to the product of the Applicable Margin (as defined in the Revolving Credit Note) multiplied by (b) the difference between (i) the maximum face amount of the Revolving Credit Note and (ii) the average daily aggregate principal balance of all Revolving Loans outstanding during each of CHC's fiscal quarters. Such fee shall be computed and shall be payable quarterly in arrears as of the end of each of CHC's fiscal quarters. Bank shall invoice Borrower for such fees, which invoice shall be due and payable within fifteen (15) days after receipt.

The provisions of Chapter 346 of the Texas Finance Code are specifically declared by the parties not to be applicable to any of the Loan Documents or the transactions contemplated thereby.

2.3 Maximum Interest Rate. At no time shall any Applicable Interest Rate or default rate in respect of any Indebtedness hereunder, exceed the Maximum Legal Rate. In the event that any interest is charged or otherwise received by Bank in excess of the Maximum Legal Rate, Borrower hereby acknowledges and agrees that any such excess interest shall be the result of an accidental and bona fide error, and any such excess shall be deemed to have been payment of principal, and not of interest, and shall be applied to the Indebtedness pursuant to the Revolving Credit Note.

2.4 Receipt of Payments by Bank. Any payment by Borrower of any of the Indebtedness made by mail will be deemed tendered and received by Bank only upon actual receipt thereof by Bank at the address designated for such payment, whether or not Bank has authorized payment by mail or in any other manner, and such payment shall not be deemed to have been made in a timely manner unless actually received by Bank on or before the date due for such payment, time being of the essence. Borrower expressly assumes all risks of loss or liability resulting from non-delivery or delay of delivery of any item of payment transmitted by mail or in any other manner. Acceptance by Bank of any payment in an amount less than the amount then due shall be deemed an acceptance on account only, and any failure to pay the entire amount then due shall constitute and continue to be an Event of Default. Prior to the acceleration of the Indebtedness, Borrower shall have the right to direct the application of any and all payments made to Bank hereunder to the Indebtedness evidenced by the Revolving Credit Note evidencing the Indebtedness. Borrower waives the right to direct the application of any and all payments received by Bank hereunder at any time or times after the acceleration of the Indebtedness. Borrower further agrees that after the occurrence of the acceleration of the Revolving Credit Note, if Borrower has failed to direct such application, to the extent permitted by law, Bank shall have the continuing exclusive right to apply and to reapply any and all payments received by Bank at any time or times, whether as voluntary payments, proceeds from any Collateral, offsets, or otherwise, against the Indebtedness in such order and in such manner as Bank may, in its sole discretion, deem advisable, notwithstanding any entry by Bank upon any of its books and records.

3.1 Authority. Each Loan Party and, if applicable, each of its partners and members who is not a natural Person is duly organized or formed, validly existing and (where appropriate) in good standing under the laws of the jurisdiction of its organization and is duly qualified and authorized to do business in each other jurisdiction in which the character of its assets or the nature of its business makes such qualification necessary.

3.2 Due Authorization. Each Loan Party has all requisite power and authority to execute, deliver and perform its obligations under each Loan Document to which it is a party or is otherwise bound, all of which have been duly authorized by all necessary action, and are not in contravention of law or the terms of any Loan Party's organizational or other governing documents.

3.3 Title to Property. Each Loan Party has good title to all property and assets purported to be owned by it, including those assets identified on the financial statements most recently delivered to Bank.

3.4 Encumbrances. There are no security interests or other Liens or encumbrances on, and no financing statements on file with respect to, any of the property or assets of any Loan Party, except for Permitted Encumbrances.

3.5 Subsidiaries. Borrower has no Subsidiaries except those specifically disclosed in Section 1.1, Defined Terms.

3.6 Taxes. Each Loan Party has filed, on or before their respective due dates, all federal, state, local and foreign tax returns which are required to be filed, or has obtained extensions for filing such tax returns, and is not delinquent in filing such returns in accordance with such extensions, and has paid all taxes which have become due pursuant to those returns or pursuant to any assessments received by any such party, as the case may be, to the extent such taxes are not delinquent, except to the extent such tax payments are being actively and diligently contested in good faith by appropriate proceedings, and if requested by Bank, have been bonded or reserved in an amount and manner satisfactory to Bank.

3.7 No-Defaults. There exists no default (or event which, with the giving of notice or passage of time, or both, would result in a default) under the provisions of any instrument or agreement evidencing, governing, securing or otherwise relating to any Debt of any Loan Party or pertaining to any of the Permitted Encumbrances.

3.8 Enforceability of Agreement and Loan Documents. Each Loan Document has been duly executed and delivered by duly authorized officer(s) or other representative(s) of each Loan Party and constitutes the valid and binding obligation of each Loan Party, enforceable in accordance with its terms, except to the extent that enforcement thereof may be limited by applicable bankruptcy, reorganization, insolvency, moratorium or similar laws affecting the enforcement of creditors' rights generally at the time in effect.

3.9 Non-contravention. The execution, delivery and performance by each Loan Party of the Loan Documents to which such Loan Party is a party or otherwise bound, are not in contravention of the terms of any indenture or other material agreement or undertaking to which any such Loan Party is a party or by which it is bound, except to the extent that such terms have been waived or that failure to comply with any such terms would not have a Material Adverse Effect.

3.10 Actions, Suits, Litigation or Proceedings. There are no actions, suits, litigation or proceedings, at law or in equity, and no proceedings before any arbitrator or by or before any Governmental Authority, pending, or, to the best knowledge of Borrower, threatened against or affecting any Loan Party, which, if adversely determined, could materially impair the right of any Loan Party to carry on its business substantially as now conducted or could have a Material Adverse Effect. No Loan Party is under investigation by, or is operating under any restrictions imposed by, any Governmental Authority.

3.11 Compliance with Laws. Each Loan Party has complied with all Governmental Requirements, including, without limitation, Environmental Laws, to the extent that failure to so comply could have a Material Adverse Effect.

3.12 Consents, Approvals and Filings, Etc. Except as have been previously obtained or as otherwise expressly provided in this Agreement, no authorization, consent, approval, license, qualification or formal exemption from, or any filing, declaration or registration with, any Governmental Authority and no material authorization, consent or approval from any other Person, is required in connection with the execution, delivery and performance by any Loan Party of any Loan Document to which it is a party. All such authorizations, consents, approvals, licenses, qualifications, exemptions, filings, declarations and registrations which have previously been obtained or made, as the case may be, are in full force and effect and are not the subject of any attack, or to the knowledge of Borrower, any threatened attack, in any material respect, by appeal, direct proceeding or otherwise

3.13 Environmental Representations. No Loan Party has used Hazardous Materials on, in, under or otherwise affecting any real or personal property now or at any time owned, occupied or operated by such Person or upon which such Person has a place of business which, in any manner, violates any Environmental Law, to the extent any such violation could result in a Material Adverse Effect, and to the best of Borrower's knowledge, no prior or current owner, occupant or operator of any of such property does or has used any Hazardous Materials on or affecting such property in any manner which violates any Environmental Law to the extent that any such violation could result in a Material Adverse Effect. No Loan Party has received any notice of any violation of any Environmental Law, and to the best knowledge of the Borrower, there have been no actions commenced or threatened by any Person against any such property or against any Loan Party for non-compliance with any Environmental Law which, in either case, could result in a Material Adverse Effect.

3.14 Accuracy of Information. All financial statements previously furnished to Bank have been prepared in accordance with GAAP and fairly present the consolidated financial condition of CHC and its consolidated Subsidiaries as such financial statements purport to present, and the results of their respective operations as of the dates and for the periods covered thereby; and since the date(s) of said financial statements, there has been no material adverse change in the consolidated financial condition of CHC and its consolidated Subsidiaries. Each Loan Party is solvent, able to pay its debts as they mature, has capital sufficient to carry on its business and has assets the fair market value of which exceed its liabilities, and no Loan Party will be rendered insolvent, under-capitalized or unable to pay debts generally as they become due by the execution or performance of any Loan Document to which it is a party or by which it is otherwise bound.

3.15 Contracts, Agreements and Leases. To Borrower's knowledge, no Loan Party is in default (beyond any applicable period of grace or cure) in complying with any provision of any material contract, agreement, indenture, lease or instrument to which it is a party or by which it or any of its properties or assets are bound, where such default would have a Material Adverse Effect. To Borrower's knowledge, each such contract, commitment, undertaking, agreement, indenture and instrument is in full force and effect and is valid and legally binding in all material respects.

3.16 ERISA. Except as shown on Schedule 3.16, no Loan Party maintains or contributes to any employee benefit plan subject to Title IV of ERISA. Furthermore, no Loan Party has incurred any accumulated funding deficiency within the meaning of ERISA or incurred any liability to the PBGC in connection with any employee benefit plan established or maintained by such Loan Party, and no reportable event or prohibited transaction, as defined in ERISA, has occurred with respect to such plans.

3.17 No Investment Company. No Loan Party is an "investment company" within the meaning of the Investment Company Act of 1940, as amended, nor is any Loan Party "controlled" by an "investment company" within the meaning of the Investment Company Act of 1940, as amended.

3.18 No Margin Stock. No Loan Party is engaged principally, or as one of its important activities, directly or indirectly, in the business of extending credit for the purpose of purchasing or carrying margin stock, and none of the proceeds of any of the Loans will be used, directly or indirectly, to purchase or carry any margin stock or made available by any Loan Party in any manner to any other Person to enable or assist such Person in purchasing or carrying margin stock, or otherwise used or made available for any other purpose which might violate the provisions of Regulations T, U, or X of the Board of Governors of the Federal Reserve System. Terms for which meanings are provided in Regulation U of said Board of

Governors or any regulations substituted therefor, as are from time to time in effect, are used in this Section with such meanings, and these representations and warranties shall be immediately effective.

k. Any Guarantor shall default on any payment obligation when due under the Guaranty executed by such Guarantor; any Guaranty is for any reason (other than satisfaction in full of all Indebtedness and the termination of the commitment of Bank hereunder) partially (including with respect to future advances) or wholly revoked or invalidated, or otherwise ceases to be in full force and effect in any material respect, or any Guarantor or any other Person contests in any manner the validity or enforceability thereof or denies that it has any further liability or obligation thereunder.

6.2 Remedies Upon Event of Default. Upon the occurrence and at any time during the existence or continuance of any Event of Default, but without impairing or otherwise limiting the Bank's right to demand payment of all or any portion of the Indebtedness which is payable on demand, at Bank's option, Bank may give notice to Borrower declaring all or any portion of the Indebtedness remaining unpaid and outstanding, whether under the notes evidencing the Indebtedness or otherwise, to be due and payable in full without presentation, demand, protest, notice of dishonor, notice of intent to accelerate, notice of acceleration or other notice of any kind, all of which are hereby expressly waived to the extent permitted by law, whereupon all such Indebtedness shall immediately become due and payable. The foregoing rights and remedies are in addition to any other rights, remedies and privileges Bank may otherwise have or which may be available to it, whether under this Agreement, any other Loan Document, by law, or otherwise.

6.3 Waiver of Defaults. No Default or Event of Default shall be waived by Bank except in a written instrument specifying the scope and terms of such waiver and signed by an authorized officer of Bank, and such waiver and shall be effective only for the specific time(s) and purpose(s) given. No single or partial exercise of any right, power or privilege hereunder, or any delay in the exercise thereof, shall preclude other or further exercise of Bank's rights. No waiver of any Default or Event of Default shall extend to any other or further Default or Event of Default. No forbearance on the part of Bank in enforcing any of Bank's rights or remedies under any Loan Document shall constitute a waiver of any of its rights or remedies. Borrower expressly agrees that this Section may not be waived or modified by Bank by course of performance, estoppel or otherwise.

6.4 Setoff. In addition to any other rights or remedies of Bank under any Loan Document, by law or otherwise, upon the occurrence and during the continuance or existence of any Event of Default, Bank may, at any time and from time to time, without notice to Borrower (any requirements for such notice being expressly waived by Borrower), setoff and apply against any or all of the Indebtedness (whether or not then due), any or all deposits (general or special, time or demand, provisional or final) at any time held by Borrower and other indebtedness at any time owing by Bank to or for the credit or for the account of Borrower, and any property of Borrower, from time to time in possession or control of Bank, irrespective of whether or not Bank shall have made any demand hereunder or for payment of the Indebtedness and although such obligations may be contingent or unmatured, and regardless of whether any Collateral then held by Bank is adequate to cover the Indebtedness. The rights of Bank under this Section are in addition to any other rights and remedies (including, without limitation, other rights of setoff) which Bank may otherwise have. Borrower hereby grants Bank a Lien on and security interest in all such deposits, indebtedness and other property as additional collateral for the payment and performance of the Indebtedness.

6.5 Waiver of Certain Laws. To the extent permitted by applicable law, Borrower hereby agrees to waive, and does hereby absolutely and irrevocably waive and relinquish, the benefit and advantage of any valuation, stay, appraisement, extension or redemption laws now existing or which may hereafter exist, which, but for this provision, might be applicable to any sale made under the judgment, order or decree of any court, on any claim for interest on the Notes, or to any security interest or other Lien contemplated by or granted under or in connection with this Agreement or the Indebtedness.

6.6 Receiver. To the extent permitted by law, Bank, in any action or suit to foreclose upon any of the Collateral, shall be entitled, without notice or consent, and completely without regard to the adequacy of any security for the Indebtedness, to the appointment of a receiver of the business and premises in question, and of the rents and profits derived therefrom. This appointment shall be in addition to any

other rights, relief or remedies afforded Bank. Such receiver, in addition to any other rights to which he shall be entitled, shall be authorized to sell, foreclose or complete foreclosure on Collateral for the benefit of Bank, pursuant to provisions of applicable law.

6.7 Application of Proceeds of Collateral. Notwithstanding anything to the contrary set forth in any Loan Document, after an Event of Default, the proceeds of any of the Collateral, together with any offsets, voluntary payments, and any other sums received or collected in respect of the Indebtedness, may be applied in such order and manner as determined by Bank in its sole and absolute discretion.

SECTION 7. MISCELLANEOUS

7.1 Governing Law. Each Loan Document shall be deemed to have been delivered in and shall be governed by and construed and enforced in accordance with the laws of the State of Texas.

7.2 Costs and Expenses. Borrower shall pay Bank, on demand, all costs and expenses, including, without limitation, reasonable attorneys' fees and legal expenses (whether inside or outside counsel is used), incurred by Bank in perfecting, revising, protecting or enforcing any of its rights or remedies against any Loan Party or any Collateral, or otherwise incurred by Bank in connection with any Default or Event of Default or the enforcement of the Loan Documents or the Indebtedness. Following Bank's demand upon Borrower for the payment of any such costs and expenses, and until the same are paid in full, the unpaid amount of such costs and expenses shall constitute Indebtedness and shall bear interest at the default rate provided in the Revolving Credit Note.

7.3 Successors and Assigns; Participation; Confidentiality. This Agreement shall be binding upon and shall inure to the benefit of Borrower and Bank and their respective successors and assigns. The foregoing shall not authorize any assignment or transfer by Borrower of any of its respective rights, duties or obligations hereunder, such assignments or transfers being expressly prohibited. Bank, however, may freely assign, whether by assignment, participation or otherwise, its rights and obligations hereunder. Bank shall hold all non-public information obtained pursuant to the requirements of this Agreement in accordance with their customary procedures for handling confidential information of this nature and in accordance with safe and sound banking practices and in any event may make disclosure to any of their examiners, Affiliates, outside auditors, counsel and other professional advisors in connection with this Agreement or as reasonably required by any bona fide proposed or actual transferee, participant or assignee or as required or requested by any Governmental Authority or representative thereof or pursuant to legal process; provided, however, that (a) unless specifically prohibited by applicable law or court order, Bank shall notify CHC of any request by any Governmental Authority or representative thereof (other than any such request in connection with an examination of the financial condition of Bank by such Governmental Authority) for disclosure of any such non-public information prior to disclosure of such information; (b) prior to any such disclosure pursuant to this Section 7.3, Bank shall require any such bona fide transferee, participant and assignee receiving a disclosure of non-public information (i) to agree in writing to be bound by this Section 7.3 and (ii) to require such Person to require any other Person to whom such Person discloses such non-public information to be similarly bound by this Section 7.3; and (c) except as may be required by an order of a court of competent jurisdiction and to the extent set forth therein, Bank shall not be obligated or required to return any materials furnished by any Borrower or any other Loan Party.

7.4 Reliance on and Survival of Various Provisions. All terms, covenants, agreements, representations and warranties of any Loan Party made in any Loan Document, or in any certificate, report, financial statement or other document furnished by or on behalf of any Loan Party in connection with any Loan Document, shall be deemed to have been relied upon by Bank, notwithstanding any investigation heretofore or hereafter made by Bank or on Bank's behalf, and those covenants and agreements of Borrower set forth in Sections 4.8 and 4.11 hereof (together with any other indemnities of Borrower contained elsewhere in any Loan Document) shall survive the termination of this Agreement and the repayment in full of the Indebtedness.

7.5 Complete Agreement; Conflicts. This Agreement, the other Loan Documents, and any commitment letter previously issued by Bank with respect thereto (provided that in the event of any inconsistency or conflict between this Agreement and the other Loan Documents, on one hand, and such commitment letter, on the other hand, this Agreement and the Loan Documents shall control), contain the entire agreement of the parties thereto and supersede all prior agreements and understandings related to the subject matter hereof, and none of the parties shall be bound by anything not expressed in writing. In the event that, and to the extent that, any of the terms, conditions or provisions of any of the other Loan Documents are inconsistent with or in conflict with any of the terms, conditions or provisions of this Agreement, the applicable terms, conditions and provisions of this Agreement shall govern and control. Any amendments or modifications hereto shall be in writing signed by all parties.

7.6 Taxes and Fees. Unless otherwise prohibited by applicable law, should any tax (other than a tax based upon the net income of Bank) or recording or filing fee become payable in respect of any Loan Document, any of the Collateral, any of the Indebtedness or any amendment, modification or supplement hereof or thereof, Borrower agrees to pay such taxes (or reimburse Bank therefor upon demand for reimbursement), together with any interest or penalties thereon, and agrees to hold Bank harmless with respect thereto.

7.7 Notices. All notices and other communications provided for in any Loan Document (unless otherwise expressly stipulated therein) or contemplated thereby, given thereunder or required by law to be given, shall be in writing (unless expressly provided to the contrary). If personally delivered, such notices shall be effective when delivered, and in the case of mailing or delivery by overnight courier, such notices shall be effective when placed in an envelope and deposited at a post office or official depository under the exclusive care and custody of the United States Postal Service or delivered to an overnight courier, postage prepaid, in each case addressed to the parties as set forth on the signature page of this Agreement, or to such other address as a party shall have designated to the other in writing in accordance with this Section. In the case of mailing, the mailing shall be by certified or first class mail. The giving of at least five (5) days' notice before Bank shall take any action described in any notice shall conclusively be deemed reasonable for all purposes; provided, that this shall not be deemed to require Bank to give such five (5) days' notice, or any notice, if not specifically required to do so in this Agreement.

7.8 Further Action. Borrower, from time to time, upon written request of Bank, will promptly make, execute, acknowledge and deliver, or cause to be made, executed, acknowledged and delivered, all such further and additional instruments, and promptly take all such further action as may be reasonably required to carry out the intent and purpose of the Loan Documents, and to provide for the Loans thereunder and payment of the Notes, according to the intent and purpose therein expressed.

7.9 Indulgence. No delay or failure of Bank in exercising any right, power or privilege hereunder or under any of the Loan Documents shall affect such right, power or privilege, nor shall any single or partial exercise thereof preclude any further exercise thereof, nor the exercise of any other right, power or privilege available to Bank. The rights and remedies of Bank hereunder are cumulative and are not exclusive of any rights or remedies of Bank.

7.10 Headings and Construction of Terms. The headings of the various sub-Sections hereof are for convenience of reference only and shall in no way modify or affect any of the terms or provisions hereof. Where the context herein requires, the singular number shall include the plural, and any gender shall include any other gender.

7.11 Independence of Covenants. Each covenant hereunder shall be given independent effect so that if a particular action or condition is not permitted by any such covenant, the fact that it would be permitted by an exception to, or would be otherwise within the limitations of, another covenant shall not avoid the occurrence of any Default or Event of Default.

7.12 Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same agreement.

7.13 WAIVER OF JURY TRIAL. BANK AND BORROWER EACH ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. EACH OF THEM, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT, WITH COUNSEL OF THEIR CHOICE, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT EITHER OF THEM MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF ANY LOAN DOCUMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THE LOAN DOCUMENTS OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTION OF EITHER OF THEM. THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR RELINQUISHED BY BANK OR BORROWER, EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY EACH OF THEM.

[THE REMAINDER OF THE PAGE IS INTENTIONALLY LEFT BLANK.]
