N.C. Gen. Stat. § 122A-9
In the discretion of the Agency any obligations issued under the provisions of this Chapter may be secured by a trust agreement by and between the Agency and a corporate trustee, which may be any trust company or bank having the powers of a trust company within or without the State. Such trust agreement or the resolution providing for the issuance of such obligations may pledge or assign all or any part of the revenues or assets of the Agency, including, without limitation, mortgage loans, mortgage loan commitments, contracts, agreements and other security or investment obligations, the fees or charges made or received by the Agency, the moneys received in payment of loans and interest thereon and any other moneys received or to be received by the Agency. Such trust agreement or resolution may contain such provisions for protecting and enforcing the rights and remedies of the holders of any such obligations as may be reasonable and proper and not in violation of law, including covenants setting forth the duties of the Agency in relation to the purposes to which obligation proceeds may be applied, the disposition or pledging of the revenues or assets of the Agency, the terms and conditions for the issuance of additional obligations, and the custody, safeguarding and application of all moneys. It shall be lawful for any bank or trust company incorporated under the laws of the State which may act as depositary of the proceeds of obligations, revenues or other money hereunder to furnish such indemnifying bonds or to pledge such securities as may be required by the Agency. Any such trust agreement or resolution may set forth the rights and remedies of the holders of any obligations and of the trustee, and may restrict the individual right of action by any such holders. In addition to the foregoing, any such trust agreement or resolution may contain such other provisions as the Agency may deem reasonable and proper for the security of the holders of any obligations. All expenses incurred in carrying out the provisions of such trust agreement or resolution may be paid from the revenues or assets pledged or assigned to the payment of the principal of and the interest on obligations or from any other funds available to the Agency.
