except as hereinafter provided, a sale or transfer of tangible personal property as an incident to the rendering of service for or by any governmental body, or for or by any corporation, society, association, foundation or institution organized and operated exclusively for charitable, religious or educational purposes or any not-for-profit corporation, society, association, foundation, institution or organization which has no compensated officers or employees and which is organized and operated primarily for the recreation of persons 55 years of age or older that has an active exemption identification number issued by the Department.

a sale or transfer of tangible personal property which is produced by the seller thereof on special order in such a way as to have made the applicable tax the Service Occupation Tax or the Service Use Tax, rather than the Retailers' Occupation Tax or the Use Tax, for an interstate carrier by rail which receives the physical possession of such property in Illinois, and which transports such property, or shares with another common carrier in the transportation of such property, out of Illinois on a standard uniform bill of lading showing the seller of the property as the shipper or consignor of such property to a destination outside Illinois, for use outside Illinois;

The purchase of such tangible personal property by the serviceman shall be subject to tax under the Retailers' Occupation Tax Act and the Use Tax Act. However, if a primary serviceman who has made the election described in this paragraph subcontracts service work to a secondary serviceman who has also made the election described in this paragraph, the primary serviceman does not incur a Use Tax liability if the secondary serviceman:

For purposes of calculating the serviceman's tax base, the selling price shall not be less than the cost price to the serviceman of the tangible personal property transferred to the service customer.
"Serviceman maintaining a place of business in this State", or any like term, means and includes any serviceman:
having or maintaining within this State, directly or by a subsidiary, an office, distribution house, sales house, warehouse or other place of business, or any agent or other representative operating within this State under the authority of the serviceman or its subsidiary, irrespective of whether such place of business or agent or other representative is located here permanently or temporarily, or whether such serviceman or subsidiary is licensed to do business in this State;
