(a) The share of the company shall not exceed ninety percent (90%) of the total principal amount of any such loan, and such participation shall be payable with interest at the same times, but not necessarily at the same interest rate, as the share of the lender, and both shares shall be equally and ratably secured by a valid mortgage on, or security interest in, real or personal property or by any other security satisfactory to the company to secure payment of the loan; however, the company’s share of any such loan may equal one hundred percent (100%) of the total principal amount of the business loan if the lender participating in the making or purchasing of such business loan by servicing the loan, purchased one hundred percent (100%) of the total amount of the bonds issued by the company in connection with or allocable to such business loan;

(b) The total principal amount of the company’s share shall not exceed ninety percent (90%) of the value of the property securing the business loan, unless the amount in excess of ninety percent (90%) is:

(ii) Insured or guaranteed by a federal agency or by a private insurer qualified to write such insurance in the state, insuring a percentage of any claim for loss at least equal to that percentage of the value by which the business loan exceeds ninety percent (90%) thereof;

(c) The value of the property securing the business loan is certified by the participating lender, on the basis of such appraisals, bids, purchase orders and engineers’ certificates as the company may require; provided that the value of items purchased and constructed from the proceeds of the business loan shall not be deemed, for purposes of this section, to exceed the contract price in respect of purchase or construction;

(d) The company shall not disburse funds under a commitment to participate in a business loan for the construction or substantial improvement of property until the construction or improvement has been completed, unless a lender furnishes an irrevocable letter of credit or a qualified corporate surety furnishes payment and performance bonds, in either event satisfactory to the company and in an aggregate amount equal to the cost of such construction or improvement;

(e) No other indebtedness may be secured by a mortgage on, or security interest in, property securing a business loan made or purchased pursuant to this section without the prior express written authorization of the company; and
