Bonds may be sold by the authority from time to time in series, and if sold in more than one series may all be authorized in one initial resolution of the board of directors with the pledges therefor made in such initial resolution although some of the details applicable to each series may be specified in the respective resolutions under which the different series are issued; provided, however, that no bonds of the authority that are authorized under Act 98-245 shall be sold or counsel hired prior to February 1, 1999. Each series of the bonds may be sold at public or private sale, as determined by the authority, at such price or prices as the authority shall determine, and, if sold at public sale either on sealed bids or at public auction, on a basis determined by the authority to enable it to effect the sale of the bonds being sold at the lowest effective borrowing cost to the authority; provided, that if in the event of public sale of the bonds no bid acceptable to the authority is received it may reject all bids. Notice of each public sale or summary notice of sale or both shall be given by publication in either a financial journal or a financial newspaper published in the City of New York, New York, and also by publication in a newspaper published in the state which is customarily published not less than five days during each calendar week, each of which notices must be published at least one time not less than 10 days prior to the date fixed for the sale. The board of directors may fix the terms and conditions under which each such sale may be held; provided, that such terms and conditions shall not conflict with any of the requirements of this article. Approval by the Governor of the terms and conditions under which any of the bonds may be issued shall be requisite to their validity, which approval signed by the Governor shall be entered on the minutes of the respective meetings of the board of directors at which the series of the bonds proposed to be issued are authorized or sold.
