S.D. Codified Laws § 1-16A-52.2
In furtherance of the powers granted in § 1-16A-52.1, the authority may acquire or enter into commitments to acquire any federally guaranteed security and to pledge or otherwise use any such federally guaranteed security in such manner as the authority deems in its best interest to secure or otherwise provide a source of repayment of any of its bonds issued to finance or refinance health or educational facilities or to enter into any appropriate agreement with any participating health or educational institution whereby the authority may make a loan to any such participating health or educational institution for the purpose of acquiring or entering into commitments to acquire any federally guaranteed security. Any agreement entered into pursuant to this section may contain such provisions which are deemed necessary or desirable by the authority for the security or protection of the authority or the holders of such bonds. However, the authority, prior to making any such acquisition, commitment or loan, shall first determine, and shall first enter into an agreement with any such participating health or educational institution or any other appropriate institution or corporation to require that the proceeds derived from the acquisition of any such federally guaranteed security will be used, directly or indirectly, for the purpose of financing or refinancing a health or educational facility.
