|(a) The offer and sale of securities by an issuer or its selling agent to a non-Texas resident not present in Texas when the offer is made is exempt from the securities registration provisions of the Securities Act. (The Securities Act provides exemptions from the securities registration requirements which might be available to some issuers or selling agents offering or selling to non-Texas residents present in the state.) (b) An issuer or selling agent who makes an offer or sale from Texas, by any means, including use of the mail or telephone, is a dealer and must comply with the dealer registration requirements of the Securities Act. (The Securities Act provides exemptions from the dealer registration requirements which might be available to some issuers or selling agents.) An offer is not deemed to be made from Texas merely because offering material is prepared in Texas, if such material is still in the possession of the issuer or its selling agent
when it leaves the state. A sale is not deemed to be made in Texas merely because a purchaser sends his purchase money to Texas, or because clerical functions connected with the closing of a sale are performed in Texas.
