 Many corporations routinely require their business partners to agree to similar provisions (such as unlimited liability and complete transfer of intellectual property). In fact, this project has explicitly been asked by corporate users of our products to agree to these exact types of clauses in the past.
 
-Therefore, we recognize that agreeing to such clauses is a standard practice in business-to-business transactions and should **pose no obstacle** for corporate users wishing to contribute to this project.
+**This CCLA was created specifically in response to those experiences.** During funding negotiations, corporate partners presented us with agreements containing the very terms listed above. When we expressed concerns about unlimited liability and IP transfer, we were told these were "standard business practices" and non-negotiable.

+**As stated in our Code of Conduct, we believe corporate participants should treat open source maintainers as equal business partners.** This means not demanding contractual terms from maintainers that the corporation's own legal department would refuse to accept if presented by a counterparty.

+If your organization cannot accept the terms in this CCLA (such as unlimited liability or complete IP transfer), then it would be inconsistent to demand that the project maintainer accept those same terms in a Maintenance Support Agreement. Organizations seeking an Authorized Exemption are expected to negotiate under terms they themselves would be willing to accept.
