Here's an interactive PDF form document containing a stripped-down arbitration clause, entitled "Arbitration provisions rider," version Adrian (I'm basing the version names on those of hurricanes). Feel free to use this document as follows:

• open the PDF document in Adobe Acrobat Reader (version 7.0 and up);
• check the boxes, fill in the blanks, etc., for the provisions you want, in collaboration with your legal counsel;
• print out the form document (the commentary in the right-hand margin, denoted by icons symbolizing yellow sticky notes and red keys, can be seen on the screen but won't print);
• attach the printout to, and incorporate it by reference in, your contract.  (The form document should not be relied on as a substitute for legal advice, of course; ask your lawyer if it's right for you.)
