(1) At any time and from time to time, holders of Series A Preferred Stock can convert such shares into shares of common stock of Clarion Technologies, Inc. by multiplying the number of shares to be converted by $1,000 and dividing that result by the conversion price then in effect, initially $1.75. The conversion price is subject to adjustment as a result of subdivisions or combinations of common stock, reorganizations, reclassifications, consolidations, mergers, sales of all or substantially all of Clarion Technologies, Inc.'s assets, or if Clarion Technologies, Inc., in certain circumstances, issues common stock at below fair market value prices. The holder of the Series A Preferred Stock may also convert accrued and unpaid dividends on such shares into a number of shares of common stock of Clarion Technologies, Inc. computed by dividing the amount of accrued and unpaid dividends by the conversion price then in effect.
(2) The Series A Preferred Stock is subject to mandatory redemption on June 30, 2007 and does not have an expiration date.
