Obligation of the Company to Complete the Project and to Pay Costs in Event Project Fund Insufficient. If the moneys in the Project Fund available for payment of the Cost of the Project are not sufficient to pay the Cost of the Project in full, the Company will complete or cause to be completed the Project and pay or cause to be paid all of that portion of the Cost of the Project in excess of the moneys available therefor in the Project Fund. The Issuer does not make any warranty, either express or implied, that the moneys which will be paid into the Project Fund will be sufficient to pay the Cost of the Project. If the Company shall pay any portion of the Cost of the Project pursuant to the provisions of this Section 3.7, it shall not be entitled to any reimbursement therefor from the Issuer, the Trustee or the holders of any of the Bonds, nor shall it be entitled to any diminution in or postponement of the Loan Payments required in Section 4.2 hereof to be paid by the Company.
If, upon the Completion Date for the Project, there shall be any surplus funds remaining in the Project Fund not reserved to pay for the Cost of the Project, such funds shall, (a) be deposited in the Bond Fund and used, at the earliest date permissible under the terms of the Indenture without the payment of a call premium or penalty, to pay principal on the Bonds through redemption or retirement; and (b) be invested as provided for in the Indenture until such time as such surplus funds are expended as provided for in this Section 3.7.
