The Escrow Agent shall be fully authorized and protected in acting on such joint instructions or court order, decree or judgment without further question and shall release to the Buyer a number of Escrow Shares set forth in such joint written instructions or, with respect to a court order, decree or judgment, in the Buyer’s Section 3.2 Certificate, from (and only to the extent of) the amounts held in the Escrow Account, and such distribution shall be made on or before the third Business Day following the date on which such joint instructions or the Buyer’s Section 3.2 Certificate, as applicable, are received by the Escrow Agent (and only to the extent of the Escrow Shares held in the Escrow Account).  “Buyer’s Section 3.2 Certificate” shall mean Buyer’s written notice to Escrow Agent and the Members’ Representative delivered promptly following final and non-appealable determination of the court order, decree or judgment, setting forth Buyer’s good faith calculation of the number of Escrow Shares having a value equal to the dollar amount (based upon the average closing price of a share of JAMDAT common stock for the fifteen (15) trading days immediately prior to such Claim date as reported by the NASDAQ National Market) of the Claim as determined in the final order, decree or judgment.

4.4                                 Escrow Shares Rights.  During the period the Escrow Shares remain in the Indemnification Escrow Fund, JAMDAT shall have all of the voting rights related to the Escrow Shares.  Any dividends or other income payable on the Escrow Shares during such period shall accumulate in escrow, be invested in Eligible Investments and be held in the Indemnification Escrow Fund for ultimate distribution with the underlying Escrow Shares.

4.5                                 Right of Substitution.  At the expense of Buyer and JAMDAT (including without limitation, reimbursement and indemnification of the Members for any amount or liability to the Escrow Agent incurred by them under Section 10 or Section 11 of this Agreement), Buyer shall have the right (“Substitution Right”) exercisable by notice given in or with Buyer’s Section 4.1 Certificate, Buyer’s Section 4.2 Certificate or Buyer’s Section 4.3 Certificate, respectively, with respect to the Escrow Shares (as adjusted for any Capital Change occurring with respect to such shares prior to release of such shares) specified therein and otherwise required to be delivered to the Members by the Escrow Agent pursuant to Section 4.1, Section 4.2 or Section 4.3, respectively, in accordance with such certificate, (i) to issue new shares of the Common Stock of JAMDAT (“Substitute JAMDAT Stock”) in the number of such Escrow Shares (as so adjusted) otherwise so required to be delivered, (ii) to require the Escrow Agent to deliver to JAMDAT the Escrow Shares otherwise so required to be delivered to the Members by the Escrow Agent, and (iii) concurrently with and against receipt by JAMDAT from the Escrow Agent of such Escrow Shares otherwise so required to be delivered to the Members by the Escrow Agent, either (A) deliver all certificates for the Substitute JAMDAT Stock directly to the Members or (B) deliver all certificates for the Substitute JAMDAT Stock to the Escrow Agent for delivery to the Members by the Escrow Agent; provided, however, a condition precedent to exercise of the Substitution Right by JAMDAT shall be the delivery by Buyer to the Members, concurrently with delivery of the certificates for the Substitute JAMDAT Stock, of an opinion of Sheppard, Mullin, Richter & Hampton LLP (or of other counsel to Buyer, which other counsel shall be reasonably acceptable to the Members) to the effect that the Substitute
