Re Conflict of Interest
Some Hackerspaces' have examples of Conflict of Interest clauses, or mentions of Interested Parties or Persons.
"Conflict of Interest
- Any member of the board who has a financial, personal, or official interest in, or conflict (or appearance of a conflict) with any matter pending before the Board, of such nature that it prevents or may prevent that member from acting on the matter in an impartial manner, will offer to the Board to voluntarily excuse him/herself and will vacate his seat and refrain from discussion and voting on said item."
http://wiki.lvl1.org/Bylaws#Conflict_of_Interest
"7.3. Restriction on Interested Persons as Directors
No more than 49 percent of the persons serving on the board may be "interested persons." An interested person is (a) any person compensated by the corporation for services rendered to it within the previous 12 months, whether as a full-time or part-time employee, independent contractor, or otherwise, excluding any reasonable compensation paid to a director as director; and (b) any brother, sister, ancestor, descendant, spouse, brother-in-law, sister-in-law, son-in-law, daughter-in-law, mother-in-law, or father-in-law of such person. However, any violation of this paragraph shall not affect the validity or enforceability of transactions entered into by the corporation."
