Debt description																								On January 1st of each year during the term of the Plan (the "Calculation Date"), the aggregate number of shares of Common Stock that are available for issuance shall automatically be increased by such number of shares as is equal to the number of shares sufficient to cause the Share Limit (as defined in the Plan) to equal twenty percent (20%) of the issued and outstanding Common Stock of the Company at such time, provided, however, that if on any Calculation Date the number of shares equal twenty percent (20%) of our total issued and outstanding Common Stock is less than the number of shares of Common Stock available for issuance under the Plan, no change will be made to the aggregate number of shares of Common Stock issuable under the Plan for that year (such that the aggregate number of shares of Common Stock available for issuance under the Plan will never decrease).
