other local governments in the region as well as school boards and other

- Q. How does the program work?
A. The program has two mechanisms the "Rider Clause" and the "Joint Solicitation".
- The Rider Clause - This is a clause in a jurisdiction's solicitation
asking bidders if they will be willing to sell to other jurisdictions
in the region, that participate in the COG Cooperative Purchasing Program,
under the same terms and conditions as those stipulated in the issuing
jurisdiction's solicitation, for the same price as being bid to the issuing
jurisdiction. There is no obligation on behalf of the vendor to sell to
those other jurisdictions and there is no obligation on behalf of the
other jurisdictions to buy from the vendor. It is a way to allow for jurisdictions
to quickly purchase commodities and services, knowing that a competitive
solicitation process has been completed. Download copy of COG
