8.

pursuant to Section 262 of the DGCL; provided, that if any such holder shall have failed to perfect or shall have effectively withdrawn or lost such holder’s right to appraisal and payment under the DGCL, such holder’s shares of Company Common Stock shall be deemed to have been converted as of the Effective Time into the right to receive the Merger Consideration (less any amounts entitled to be deducted or withheld pursuant to Section 2.11), and such shares shall not be deemed to be Dissenting Shares.
