1. A software license entitles you to use the software in one of two ways:
   • Option 1: by a single individual on one or more computers
   • Option 2: by multiple users on a single computer (but not simultaneously by more than one user)
2. Licenses may be transferred from one user to another within the company or licensed organization. Users may switch their method of using the software license (options A and B) above without notifying Sawtooth Software.
3. Users should register their software via an online registration form that appears when you launch the software. (A phone registration option is also available, for those without an internet connection.) If you postpone registration, you will be prompted to register the software each time you start the software. Periodically, audits will be performed and a report will be sent to customers regarding their license registration activity.
4. Academic Lab users are not required to register their software. Academic ("lab") licenses are described at: http://www.sawtoothsoftware.com/education/academiclicense.shtml.
5. Only registered users may receive technical support. When you request technical support, Sawtooth Software will verify your serial number.
6. Software is sold at the list price, less any volume discounts. Software may be returned for a full refund within 60 days of software purchase.
7. A volume discount is applied to any new or upgrade purchase after a specified level of expenditure within the past 3 years with us or our European representative, SKIM. After an expenditure of $10K, subsequent purchases receive a 10% discount, after an expenditure of $25K the discount is 25%, and after an expenditure of $50K the discount is 50%.
8. Upgrade fees will be uniform (typically about 40% of the new license fee), regardless of the prior version you own. Older “Category” style licenses may retain "Category" scope only for system size upgrades (not version upgrades).
9. For existing users who do not wish to upgrade, we will continue to support their old licenses (our track record has been to support older versions in terms of bug fixes for around 3 years and to offer technical support for often 10 years).
