authorities expressly conferred upon Directors by statute.




         11.    No contract or other transaction between the corporation and one
or more of its Directors or any other corporation, firm, association or entity
in which one or more of its Directors are Directors or Officers or are
financially interested, shall be either void or voidable because of such
relationship or interest or because such Director or Directors are present at
the meeting of the Board of Directors or a committee thereof which authorizes,
approves or ratifies such contract or transaction, if the contract or
transaction is fair and reasonable to the corporation and if either:

         (1)    The fact of such relationship or interest is disclosed to the
Board of Directors or committee which authorizes, approves or ratifies the
contract or transaction by a vote or consent sufficient for the purpose without
counting the votes or consents of such interested Directors; or

         (2)    The fact of such relationship or interest is disclosed to the
shareholders entitled to vote and they authorize, approve or ratify such
contract or transaction by vote or written consent. Common or interested
Directors may not be counted in determining the presence of a quorum at a

approves or ratifies such contract or transaction.
