Notwithstanding anything contained herein to the contrary, the Company shall not be obligated to indemnify or hold harmless the Issuer or the Trustee, or their respective members, officers, officials, directors, trustees or employees, for their gross negligence or willful misconduct.

Section 7.01. Events of Default. Each of the following shall be an Event of Default:

(a)          The Company shall fail to pay the amounts required to be paid under Section 4.01 or 4.02 on the dates specified therein;

(b)          Failure by the Company to observe and perform any covenant, condition or agreement on its part to be observed or performed, other than as referred to in Section 7.01(a), (other than certain representations, warranties and covenants regarding various matters relating to the tax status of the Bonds) for a period of 60 days after written notice specifying such failure and requesting that it be remedied shall have been given to the Company by the Issuer or the Trustee, unless the Issuer and the Trustee shall agree in writing to an extension of such time prior to its expiration; provided, however, if the failure stated in the notice cannot be corrected within the applicable period, it shall not constitute an Event of Default if corrective action is instituted by the Company within the applicable period and is being diligently pursued until the default is corrected;

(c)          The dissolution or liquidation of the Company or the voluntary initiation by the Company of any proceeding under any federal or state law relating to bankruptcy, insolvency, arrangement, reorganization, readjustment of debt or any other form of debtor relief, or the initiation against the Company of any such proceeding which shall remain undismissed for 60 days, or failure by the Company to promptly have discharged any execution, garnishment or attachment of such consequence as would materially impair the ability of the Company to carry on its operations, or assignment by the Company for the benefit of creditors, or the entry by the Company into an agreement of composition with creditors or the failure generally by the Company to pay its debts as they become due; or

(d)          The occurrence of an Event of Default as defined in the Indenture.

Any declaration of default under subparagraph (c) and the exercise of remedies upon any such declaration will be subject to any applicable limitations of federal bankruptcy law affecting or precluding that declaration or exercise during the pendency of or immediately following any bankruptcy, liquidation or reorganization proceedings.

Section 7.02. Remedies on Default. Whenever an Event of Default shall have happened and be existing, any one or more of the following remedial steps may be taken:

(a)          if acceleration of the principal amount of the Bonds has been declared pursuant to Section 7.03 of the Indenture, the Issuer or the Trustee shall declare all Installment Payments to be immediately due and payable, whereupon the same shall become immediately due and payable; or

(b)          the Issuer or the Trustee may pursue all remedies now or hereafter existing at law or in equity to collect all amounts then due and thereafter to become due under this Agreement or to enforce the performance and observance of any other obligation or agreement of the Company under those instruments.

Notwithstanding the foregoing, the Trustee shall not be obligated to take any step that in its reasonable opinion will or might cause it to expend time or money or otherwise incur liability unless and until a satisfactory indemnity bond has been furnished to the Trustee at no cost or expense to it. Any amounts collected pursuant to action taken under this Section (except for amounts payable directly to the Issuer or the Trustee pursuant to Section 3.05, 4.02, 5.02 or 7.04) shall be paid into the Bond Fund and applied in accordance with the provisions of the Indenture or, if the Outstanding Bonds have been paid and discharged in accordance with the provisions of the Indenture, shall be paid as provided in Section 9.01 of the Indenture for transfers of remaining amounts in the Bond Fund.

The provisions of this Section are subject to the further limitation that the rescission by the Trustee of its declaration that all of the Bonds are immediately due and payable also shall constitute an annulment of any corresponding declaration made pursuant to paragraph (a) of this Section and a waiver and rescission of the consequences of that declaration and of the Event of Default with respect to which that declaration has been made, provided that no such waiver or rescission shall extend to or affect any subsequent or other default or impair any right consequent thereon.

Section 7.03. 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 remedy shall be cumulative and shall be in addition to every other remedy given under this Agreement, now or hereafter existing at law, in equity or by statute. No delay or omission to exercise any right or power accruing upon any default shall impair that right or power or shall be construed to be a waiver thereof, but any such right and 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 any notice required by law or for which express provision is made herein.

Section 7.04. Agreement to Pay Fees and Expenses. If an Event of Default should occur and the Issuer or the Trustee should incur expenses, including attorneys’ fees, in connection with the enforcement of this Agreement or the collection of sums due hereunder, the Company shall reimburse the Issuer and the Trustee, as applicable, for the reasonable expenses so incurred upon demand.

Section 7.05. No Waiver. No failure by the Issuer or the Trustee to insist upon the performance by the Company of any provision hereof shall constitute a waiver of their right to performance and no express waiver shall be deemed to apply to any other existing or subsequent right to remedy the failure by the Company to observe or comply with any provision hereof.

Section 7.06. Notice of Default. The Company shall notify the Trustee immediately and in writing if it becomes aware of the occurrence of any Event of Default hereunder or of any fact, condition or event which, with the giving of notice or passage of time or both, would become an Event of Default.
