There shall be four alternate members of the Planning Board who shall be appointed by the appointing authority and shall meet the qualifications of Class IV members of the Planning Board. The alternates shall be designated at the time of their appointment as "Alternate No. 1;" "Alternate No. 2;" "Alternate No. 3;" and "Alternate No. 4." The terms of the alternate members shall be for two years except that the terms of the alternate members shall be such that the term of not more than two alternate members shall expire in any one year; provided, however, that in no instance shall the terms of the alternate members first appointed exceed two years. A vacancy occurring otherwise than by expiration of term shall be filed by the Planning Board for the unexpired tern only.

No alternate members shall be permitted to act on any matter on which he has either directly or indirectly any personal or financial interest. An alternate member may, after public hearing if the alternate member requests one, be removed by the Governing Body for cause. Alternate members may participate in discussions of the proceedings but may not vote except in the absence or disqualification of a regular member of any class. A vote shall not be delayed in order that a regular member may vote instead of an alternate member. In the event that a choice must be made as to which alternate member is to vote, Alternate No. 1 shall vote first, followed by Alternate No. 2, then followed by Alternate No. 3, and then followed by Alternate No. 4
