| 3. | Upon and subject to the Closing, the number of Private Placement Warrants set forth opposite each Holder’s name in Column III of Exhibit A hereto (the “$12.00 Warrants”) shall become subject to potential forfeiture, and each Holder hereby agrees not to exercise such $12.00 Warrants, unless and until a $12.00 Triggering Event (as defined below) occurs within the Earnout Period, with such $12.00 Warrants no longer being subject to forfeiture upon the occurrence of a $12.00 Triggering Event pursuant to the terms of this Letter Agreement. Prior to the occurrence of a $12.00 Triggering Event, each Holder shall not Transfer any of the $12.00 Warrants. Certificates or book entries representing the $12.00 Warrants shall bear a legend referencing that they are subject to transfer restrictions and forfeiture and are unable to be exercised in certain circumstances pursuant to the provisions of this Letter Agreement, and any warrant agent for the $12.00 Warrants will be given appropriate stop transfer orders (and related no exercise orders) with respect to the $12.00 Warrants until the occurrence of a $12.00 Triggering Event; provided, however, that upon a $12.00 Triggering Event in accordance with the terms herein, DCRB shall immediately cause the removal of such legend and direct such warrant agent that such stop transfer and no exercise orders are no longer applicable. In the event no $12.00 Triggering Event occurs during the five (5) year period commencing on the one (1) year anniversary of the Closing (the “Earnout Period”), the $12.00 Warrants shall immediately be forfeited to DCRB for no consideration and immediately cancelled. For purposes of this Letter Agreement, “$12.00 Triggering Event” means the occurrence of a date on which the last reported sales price of one share of DCRB Class A Common Stock quoted on the NASDAQ Capital Market (or the exchange on which the shares of DCRB Class A Common Stock are then listed) is greater than or equal to $12.00 (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any twenty (20) Trading Days within any thirty (30) consecutive Trading Day period within the Earnout Period; provided, that, if, during the Earnout Period, there is a Change of Control pursuant to which the holders of DCRB Class A Common Stock have the right to receive consideration implying a value of DCRB Class A Common Stock (as determined in good faith by the DCRB Board) of (i) less than $12.00 (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like), then the $12.00 Warrants shall immediately be forfeited to DCRB for no consideration and immediately cancelled; or (ii) greater than or equal to $12.00 (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like), then the $12.00 Triggering Event shall be deemed to have occurred. |
