Problems with content of Art Center promotions

A non-profit art center (similar to those found in almost all medium to large markets) who's mission is community development and artists' development, has a facility with studios that artists pay membership to use. Additionally, art classes are given on premises by the studio artists and some community artists associated with the center. There is also an event space rented out for things such as weddings, meetings, and parties.

This question concerns the art center's promotions, such as newspaper ads, brochures, website, facebook and twitter.

Is there a conflict with the center's non-profit status if, in any of these promotions, an announcement is made concerning:
1) An artist's recent award received from a different organization
2) An artist's exhibition at a different organization
3) An event held at a different organization
4) A suggestion to attend an event held at a different organization
