(c) No further Ownership Rights in Units and PDN Common Stock. All PDN Shares issued upon the delivery of the Transfer Documents in accordance with the terms hereof (and any cash paid pursuant to subsection (c) or (e) of this Section 2.2) shall be deemed to have been issued in full satisfaction of all rights pertaining to the Units so contributed and exchanged. If, after the Closing, Transfer Documents with respect to valid Units are presented to PDN for any reason, such Units shall be deemed contributed and exchanged to PDN in accordance with the provisions of this Agreement, effective as of the Closing and the Members, in exchange therefor, shall receive such number of PDN Shares as may be calculated pursuant to Section 2.1, together, without interest, with cash in lieu of fractional PDN Shares as described in Section 2.2(e).

To the extent that amounts are so withheld by PDN such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Units in respect of which such deduction and withholding was made.
