otherwise specifically provided by law, the Certificate of Incorporation or
these Bylaws, at all meetings of the Board, a majority of the entire Board
shall constitute a quorum for the transaction of business and the act of a

COMMUNICATIONS EQUIPMENT. Any one or more members of the Board, or of any
committee designated by the Board, may participate in a meeting of the Board
or any such committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation in a meeting by such means
shall constitute presence in person at such meeting.

the Corporation shall reimburse each director or member of a committee for
any expenses incurred by him on account of his attendance at any meeting of
the Board or of any committee, or both. Nothing contained in this Section
shall be construed to preclude any director from serving the Corporation in
any other capacity.

between the Corporation and one or more of its directors or officers, or
between the Corporation and any other corporation, partnership, association,
or other organization in which one or more of its directors or officers are
directors or officers, or have a financial interest, shall be void or
voidable solely for this reason, or solely because the director or officer is
present at or participates in the meeting of the Board or committee thereof
which authorizes the contract or transaction, or solely because his or their
votes are counted for such purpose if (i) the material facts as to his or
their relation-

5


ship or interest and as to the contract or transaction are disclosed or are

relationship or interest and as to the contract or transaction are disclosed
or are known to the stockholders entitled to vote thereon, and the contract
or transaction is specifically approved by the stockholders; or (iii) the
contract or transaction is fair to the Corporation as of the time it is
authorized, approved, or ratified, by the Board, a committee thereof or the
stockholders. Common or interested directors may be counted in determining
the presence of a quorum at a meeting of the Board or of a committee which
authorizes the contract or transaction.
