filings (including filings under Section 16(a) of the Exchange Act) reporting a reduction in beneficial ownership of shares shall be required or shall be voluntarily made during the Lock-Up Period
(a) such Stockholder Party shall provide the Company prior written notice informing them of such report or filing and (b) such report or filing shall disclose that such donee, trustee, distributee or transferee, as the case may be, agrees
