ARTICLE VI

SPECIAL COVENANTS AND AGREEMENTS

SECTION 6.1    Maintenance of Existence. The Company shall maintain its organizational existence, will not dissolve or otherwise dispose of all or substantially all of its assets and will not consolidate with or merge with or into another entity; provided, however, that the Company may consolidate with or merge with or into, or sell or otherwise transfer all or substantially all of its assets (and thereafter dissolve) to, another entity, organized under the laws of the United States, one of the states thereof or the District of Columbia, if the surviving, resulting or transferee entity, as the case may be (if other than the Company), prior to or simultaneously with such consolidation, merger, sale or transfer, assumes, by delivery to the Trustee of an instrument in writing satisfactory in form and substance to the Trustee, all of the obligations of the Company hereunder, including under the Note, and provided that both immediately prior to such dissolution, disposal, consolidation or merger and after giving effect thereto, no Event of Default under this Agreement (or event which, with the giving of notice or passage of time, or both, would constitute an Event of Default under this Agreement) shall have occurred and be continuing.

If a consolidation, merger or sale or other transfer is made as permitted by this Section 6.1, the provisions of this Section 6.1 shall continue in full force and effect and no further consolidation, merger or sale or other transfer shall be made except in compliance with the provisions of this Section 6.1.

SECTION 6.2    Arbitrage Covenant. The Issuer and the Company agree to comply with the terms and provisions of the Tax Certificate and covenant that the proceeds of the sale of the Bonds, the earnings thereon, and any other moneys on deposit in any fund or account maintained in respect of the Bonds (whether such moneys were derived from the proceeds of the sale of the Bonds or from other sources) will not be used in a manner which would cause the Bonds to be treated as "arbitrage bonds" within the meaning of Section 148 of the Code. The Company further covenants that: (a) all actions with respect to the Bonds required by

Section 148(f) of the Code shall be taken; (b) it shall make the determinations required by paragraph (b) of Section 7.2 of the Indenture and promptly notify the Trustee, in writing, of the same, together with supporting calculations; and (c) it shall within twenty-five (25) days after (i) the calendar date which corresponds to the final maturity of the respective series of Bonds and each anniversary thereof falling on or after the date of initial authentication and delivery thereof up to and including the final maturity of such series of the Bonds, unless the final payment, whether upon redemption in whole or at maturity, of such Bonds shall have occurred prior to such anniversary, and (ii) such final payment, file with the Trustee, a statement signed by the chief financial officer of the Company (or person performing similar functions) to the effect that the Company is then in compliance with its covenants contained in clauses (a) and (b) of this sentence, together with supporting calculations; provided, however, that if the Company shall furnish an opinion of Bond Counsel to the Trustee to the effect that no further action by the Company is required for such compliance with respect to the Bonds, the Company shall not thereafter be required to deliver any such statements or calculations.

SECTION 6.3    Bonds are Limited Obligations. The Bonds shall be limited obligations of the Issuer, payable solely out of the Revenues.

THE BONDS ARE NOT A GENERAL OBLIGATION OF THE ISSUER AND ARE NOT AN INDEBTEDNESS OF THE STATE OR ANY POLITICAL SUBDIVISION THEREOF.  NEITHER THE FAITH AND CREDIT OF THE ISSUER NOR THE FAITH AND CREDIT OR THE TAXING POWER OF THE STATE OR ANY POLITICAL SUBDIVISION THEREOF IS PLEDGED TO THE PAYMENT OF THE PRINCIPAL OF THE BONDS, OR PREMIUM, IF ANY, OR THE INTEREST THEREON OR OTHER COSTS INCIDENTAL THERETO.  THE ISSUER HAS NO TAXING POWER.

SECTION 6.4    Tax-Exempt Status of Bonds. The Issuer and the Company mutually covenant and agree that neither of them shall take or authorize or permit any action to be taken, and have not taken or authorized or permitted any action to be taken, which results in interest paid on the Bonds being included in gross income for purposes of federal income taxes. Without limiting the generality of the foregoing, the Company further covenants, represents and agrees as follows:

(a)Substantially all of the net proceeds of the sale of the Prior Bonds have been used to undertake the acquisition of air or water pollution control facilities or sewerage or solid waste disposal facilities within the meaning of Section 103(b)(4) of the 1954 Code. All of the proceeds of the Prior Bonds and the 1998 Bonds have been expended.

(b)The weighted average maturity of the Series 2019 Bonds does not exceed 120% of the reasonably expected economic life of the Project financed with the proceeds of the Prior Bonds.

(c)The principal amount of the Series 2019 Bonds shall not exceed the outstanding principal amount of the 1998 Bonds.

(d)The Series 2019 Bonds are not and will not be "federally guaranteed" (as defined in Section 149(b) of the Code).

(e)None of the proceeds of the Series 2019 Bonds will be used, and none of the proceeds of the Prior Bonds or the 1998 Bonds were used, to provide any airplane, skybox or other private luxury box, or health club facility, any facility primarily used for gambling, or any store the principal business of which is the sale of alcoholic beverages for consumption off premises.

(f)The information furnished by the Company and used by the Issuer in preparing its Tax Certificate dated the issue date of the Series 2019 Bonds is accurate and complete as of the date of the issuance of the Series 2019 Bonds.

(g)None of the proceeds of the Series 2019 Bonds will be used to finance Costs of Issuance of the Series 2019 Bonds.

(h)The Company will take no action that would cause any funds constituting gross proceeds of the Series 2019 Bonds to be used in a manner as to constitute a prohibited payment under the applicable regulations pertaining to, or in any other fashion as would constitute failure of compliance with, Section 148 of the Code and the applicable regulations thereunder.

The Company will not knowingly take any action, or knowingly omit to take any action, which action or omission will adversely affect the excludability from gross income of the holders thereof for federal income tax purposes of interest on the Bonds (other than holders who are substantial users of the Project or related persons within the meaning of section 147(a) of the Code) and, in the event of such action or omission (whether taken with knowledge or not), will promptly, upon receiving knowledge thereof, take all lawful actions, based on advice of Bond Counsel and at the Company's expense, as may rescind or otherwise negate such action or omission.

The Company further covenants and agrees that it will not use or permit the use by any person of any of the funds provided by the Issuer hereunder or any other of its funds, directly or indirectly, or direct the Trustee to invest any funds held by it under the Indenture or this Agreement, in such manner as would, or enter into, or allow any "related person" (as defined in Section 103(b)(13) of the 1954 Code) to enter into, any arrangement, formal or informal, that would, or take or omit to take any other action that would, cause any Bond to be an "arbitrage bond" within the meaning of Section 148(a) of the Code or result in the loss of the excludability from gross income for federal income tax purposes of the interest paid on the Bonds to the extent afforded under Section 103 of the 1954 Code. The Company acknowledges Section 7.2 of the Indenture and agrees to perform all duties imposed upon it by such Section including but not limited to its obligations under the Tax Certificate.

The covenants and agreements contained in this Section 6.4 shall survive any termination of this Agreement.

SECTION 6.5    Compliance with Law. The Company shall, throughout the term of this Agreement and at no expense to the Issuer, promptly comply or exercise all of its rights, powers, elections and options under the Plant Agreements to cause compliance with all laws, ordinances, orders, rules, regulations and requirements of duly constituted public authorities that are applicable to the Project or to the repair and alteration thereof, or to the use or manner of use of the Project and which, if there is non-compliance, would materially adversely affect or impair the obligations of the Company under this Agreement or the ability of the Company to discharge such obligations. Notwithstanding the foregoing, the Company shall have the right to contest the legality of any such law, ordinance, order, rule, regulation or requirement as applied to the Project; provided that, in the opinion of counsel to the Company, such contest shall not in any way materially adversely affect or impair the obligations of the Company under this Agreement or the ability of the Company to discharge such obligations.

SECTION 6.6    No Warranty. The Issuer makes no warranty, either express or implied, as to the Project, including, without limitation, title to the Project or the actual or designed capacity of the Project, as to the suitability or operation of the Project for the purposes specified in this Agreement, as to the condition of the Project or as to the suitability thereof for the Company's purposes or needs or as to compliance of the Project with applicable laws and regulations or as to the ability of the Company to discharge the Bonds. The Company covenants with the Issuer that it will make no claim against the Issuer for any deficiency which may at any time exist in the Project, nor will it assert against the Issuer any other claim for breach of warranty with respect to the Project. The obligations of the Company under this Section shall survive any assignment or termination of this Agreement.

SECTION 6.7    Continuing Disclosure. It is understood, acknowledged and agreed that the Issuer shall have no responsibility for compliance with the continuing disclosure requirements set forth in Rule 15c2-12 promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as in effect on the date of this Agreement, and shall have no liability to the Underwriter, the holders of the Bonds or any other person with respect to such disclosure matters. To the extent applicable to the Company, the Company agrees to comply fully with the continuing disclosure requirements of said Rule 15c2-12.

After any lease or sale of any element or unit of the Project, or any interest therein, such element or unit, or interest therein, shall no longer be deemed to be part of the Project for the purposes of this Agreement.

Upon any such lease or sale, the Company shall comply with the requirements of Section 6.4 hereof, the 1954 Code and the Code and the regulations promulgated thereunder (including, without limitation, the taking of remedial action with respect to the Bonds) as the same may then be applicable.

The provisions of Section 8.1 hereof are subject to the following limitations: If by reason of acts of God; strikes, lockouts or other industrial disturbances; acts of public enemies; orders or other acts of any kind of the government of the United States or of the State of Mississippi, or any other sovereign entity or body politic, or any department, agency, political subdivision, court or official

of any of them, or any civil or military authority; insurrections; riots; epidemics; landslides; lightning; earthquakes; volcanoes; fires; hurricanes; tornados; storms; floods; washouts; droughts; arrests; restraint of government and people; civil disturbances; explosions; breakage of, or accident to, machinery; partial or entire failure of utilities; or any cause or event not reasonably within the control of the Company, the Company is unable in whole or in part to carry out any one or more of its agreements or obligations contained herein, other than its obligations under Section 5.2 hereof to pay the Loan Payments and its obligations under Sections 5.7, 6.1, 6.4 and 9.1 hereof, the Company shall not be deemed in default by reason of not carrying out said agreement or agreements or performing said obligation or obligations during the continuance of such inability.

SECTION 8.3    Remedies on Default.

(a)Upon the occurrence and continuance of any Event of Default described in clauses (a), (c) or (d) of Section 8.1 hereof, and further upon the condition that, in accordance with the terms of the Indenture, the Bonds shall have become immediately due and payable pursuant to any provision of the Indenture, the Loan Payments required to be paid pursuant to Section 5.2 hereof shall, without further action, become and be immediately due and payable.

(c)Any amounts collected pursuant to action taken under this Section shall be applied in accordance with the Indenture.

(d)In case any proceeding taken by the Issuer or the Trustee on account of any Event of Default shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Issuer or the Trustee, then and in every such case the Issuer and the Trustee shall be restored to their former positions and rights hereunder, respectively, and all rights, remedies and powers of the Issuer and the Trustee shall continue as though no such proceeding had been taken.

SECTION 8.4    No Remedy Exclusive. No remedy conferred upon or reserved to the Issuer or the Trustee by this Agreement is intended to be exclusive of any other available remedy or remedies, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given under this Agreement or now or hereafter existing at law or in equity or by statute. No delay or omission to exercise any right or power accruing upon any Event of Default shall impair any such right or power or shall be construed to be a waiver thereof, but any such right or power may be exercised from time to time and as often as may be deemed expedient. In order to entitle the Issuer or the Trustee to exercise any remedy reserved to it in this Article, it shall not be necessary to give any notice other than such notice as may be required in this Article.

In the event that any agreement contained herein shall be breached by either the Company or the Issuer and such breach shall thereafter be waived by the other party, such waiver shall be limited to the particular breach so waived and shall not be deemed to waive any other breach hereunder. In view of the assignment of the Issuer's rights in and under this Agreement to the Trustee under the Indenture, the Issuer shall have no power to waive any default hereunder by the Company without the consent of the Trustee. Any waiver of any "Event of Default" under the Indenture and a rescission and annulment of its consequences shall constitute a waiver of the corresponding Event of Default hereunder and a rescission and annulment of the consequences thereof.

misuse by third parties; (b) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Issuer or the Company; (c) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (d) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

Any of the foregoing may, by notice given hereunder, designate any further or different addresses to which subsequent notices, certificates or other communications shall be sent.

SECTION 10.2    Severability. If any provision of this Agreement shall be held or deemed to be or shall, in fact, be illegal, inoperative or unenforceable, the same shall not affect any other provision or provisions herein contained or render the same invalid, inoperative, or unenforceable to any extent whatever.

SECTION 10.3    Execution of Counterparts. This Agreement may be simultaneously executed in several counterparts, each of which shall be an original and all of which shall constitute but one and the same instrument.

SECTION 10.4    Amounts Remaining in Bond Fund. It is agreed by the parties hereto that after payment in full of (i) the Bonds (or the provision for payment thereof having been made in accordance with the provisions of the Indenture), (ii) the Administration Expenses of the Issuer, and (iii) all other amounts required to be paid under this Agreement and the Indenture, any amounts remaining in the Bond Fund shall belong to and be paid by the Trustee, upon written instruction, to the Company.

SECTION 10.5    Amendments, Changes and Modifications. Except as otherwise provided in this Agreement or the Indenture, subsequent to the initial issuance of Bonds and prior to payment in full of the Bonds (or provision for payment thereof having been made in accordance with the provisions of the Indenture), this Agreement may not be effectively amended, changed, modified, altered or terminated nor any provision waived without the written consent of the Trustee, which shall not be unreasonably withheld.

SECTION 10.6    Governing Law. This Agreement shall be governed exclusively by and construed in accordance with the applicable laws of the State of Mississippi.

SECTION 10.7    Authorized Company Representatives. An Authorized Company Representative shall act on behalf of the Company whenever the approval of the Company is required or the Company requests the Issuer to take some action, and the Issuer and the Trustee shall be authorized to act on any such approval or request and neither party hereto shall have any complaint against the other or against the Trustee as a result of any such action taken.

SECTION 10.8    Term of the Agreement. This Agreement shall be in full force and effect from the date hereof until the right, title and interest of the Trustee in and to the Trust Estate (as defined in the Indenture) shall have ceased, terminated and become void in accordance with Article IX of the Indenture and until all payments required under this Agreement shall have been made.

SECTION 10.9    No Personal Liability. No covenant or agreement contained in this Agreement shall be deemed to be the covenant or agreement of any official, officer, agent, or employee of the Issuer in his individual capacity, and no such person shall be subject to any personal liability or accountability by reason of the issuance thereof.

SECTION 10.10    Parties in Interest. This Agreement shall inure to the benefit of and shall be binding upon the Issuer, the Company, the Trustee and their respective successors and assigns, and no other person, firm or corporation shall have any right, remedy or claim under or by reason of this Agreement; provided, however, that any monetary obligation of the Issuer created by or arising out of this Agreement shall be payable solely out of the Revenues and shall not constitute, and no breach of this Agreement by the Issuer shall impose, a pecuniary liability upon the Issuer or a charge upon the Issuer's general credit.
