Something I’ve been doing for awhile is to capitalize IF and THEN in a complex sentence, and to use colons and semi-colons to set them off. For example:
IF: A Product includes computer software, including for example software embedded in hardware; THEN: Reseller may not copy, disassemble, decompile, or reverse engineer the software, nor assist or knowingly permit others to do so, without Provider’s express prior written approval.
(Bold-faced emphasis added.)
