(B) The resolution under which the bonds are authorized to be issued or any security agreement, including an indenture or trust indenture to be entered into in connection therewith, may contain any agreements and provisions customarily contained in instruments securing bonds, including, without limiting, provisions respecting the fixing and collection of obligations, the creation and maintenance of special funds, and the rights and remedies available, in the event of default, to the bondholders or to the trustee under such security agreement as the authority considers advisable. In making such agreements the authority does not have the power to obligate itself except with respect to program funds and cannot incur a pecuniary liability or a charge upon the general credit of the authority or of the State or against the taxing powers of the State. The resolution of the authority authorizing any bonds and any security agreement securing bonds may provide that, in the event of default in payment of the principal of or the interest on such bonds or in the performance of any agreement contained in such proceedings or security agreement, the payment and performance may be enforced by mandamus or by the appointment of a receiver in equity with power to charge and collect any obligations and to apply any revenues pledged in accordance with such proceedings or the provisions of the security agreement. Any security agreement may provide also that, in the event of default in payment or the violation of any agreement contained in the security agreement, it may be foreclosed by proceedings at law or in equity, and may provide that any trustee under the security agreement or the holder of any of the bonds secured thereby may become the purchaser at any foreclosure sale, if he is the highest bidder. No breach of any such agreement may impose any pecuniary liability upon the State or the authority or any charge upon the general credit of the authority or of the State or against the taxing power of the State. Subject to the approval of the State Treasurer, the trustee under any security agreement, or any depository specified by the security agreement, may be such person or corporation as the authority may designate, notwithstanding that he may be a nonresident of South Carolina or incorporated under the laws of the United States or any of the states. Monies in the funds and accounts held by the trustee shall be invested or deposited by the trustee.
