The corporation may make rules and regulations governing the qualifications of bidders entering into such a contract where the cost of such a contract exceeds ten thousand dollars. The bidding may be restricted to those who shall have qualified prior to the receipt of bids according to standards fixed by the corporation; provided, however, that notice or notices for the submission of qualifications shall be published in a newspaper with a general circulation in the region at least once, not less than ten days prior to the date fixed for the filing of qualifications.3. It shall be a misdemeanor for a director of the corporation or an officer, agent, executive or other employee retained, employed or appointed by the corporation to be in any manner or way interested, directly or indirectly, as principal, surety or otherwise in a contract, the expense or consideration whereof is payable out of funds of the corporation.N.Y.
