All other provisions of this Agreement shall be effective and binding upon the parties hereto upon the execution of this Agreement by the parties hereto.3. Escrow Arrangements3.1 Notwithstanding the terms of Schedule 9 to the Deed Poll, the parties agree that if the Effective Time occurs: (A) Loudeye shall continue to retain the Loudeye Shares issued by it prior to the date hereof that are currently being held by Loudeye as Escrow Shares (in the amounts set forth in column 3 of Schedule 1 hereto), and such Loudeye Shares shall continue to constitute Escrow Shares and shall be held subject to the terms and conditions of Schedule 9 to the Deed Poll; and (B) Each of the Obligors irrevocably directs Loudeye to (and consents and agrees to) Loudeye retaining from each Obligor’s aggregate entitlement to Cash Payments and Accelerated Consideration Shares pursuant to the Acquisition Amendment, the amount of cash set forth opposite such Obligor’s name in column 4 of Schedule 1 hereto (the “ACCELERATED CONSIDERATION ESCROW CASH”) and the number of Accelerated Consideration Shares set forth opposite such Obligor’s name in column 5 of Schedule 1 hereto (the “ACCELERATED CONSIDERATION ESCROW SHARES”). The Accelerated Consideration Escrow Cash and Accelerated Consideration Escrow Shares retained by Loudeye pursuant to this Clause 3.1(B) shall be treated as Escrow Cash and Escrow Shares, respectively, for purposes of Schedule 9 to the Deed Poll, shall be held subject to the terms and conditions of Schedule 9 to the Deed Poll and shall be deemed to satisfy all retentions which Loudeye would otherwise be permitted to make pursuant to Schedule 9 to the Deed Poll in respect of 3 the Cash Payments and the Accelerated Consideration Shares; provided that Loudeye shall itself hold back the Accelerated Consideration Escrow Cash in lieu of depositing such amounts in an Escrow Account. For the avoidance of doubt, Loudeye shall only be entitled to retain 50% of the Accelerated Consideration Escrow Cash upon payment of the First Cash Payment with the remaining 50% being retained upon payment of the Second Cash Payment.(C) Mike Large agrees that: (a) either (i) he shall deposit with Loudeye (and agrees that Loudeye may retain) the number of Loudeye Shares opposite his name in column 6 of Schedule 1 hereto as Escrow Shares (subject to the terms and conditions of Schedule 9 to the Deed Poll) as and when he exercises options held by him with respect to the Large Escrow Shares (as defined below); or (ii) he shall leave unexercised sufficient number of options as represents that number of Loudeye Shares opposite his name in column 6 of Schedule 1, (such shares, the “LARGE ESCROW SHARES”) (and the obligations in this clause shall be in substitution for his obligations under paragraphs 2.1 and 2.2 of Schedule 9 of the Deed Poll); and (b) if at any time when he still holds options to purchase Loudeye Shares he would, if such options had been exercised at that time, have become obliged pursuant to the terms of the Deed Poll to waive his right to such Loudeye Shares which would fall to be issued upon exercise of such options, Loudeye shall be entitled to cancel his options to purchase the Loudeye Shares which he would otherwise have waived the right to receive.(D) The following amendments shall be made to Schedule 9 to the Deed Poll: (a) in paragraph 6.1, the definition of “B” shall be amended to read “a fraction, the numerator of which is the aggregate amount of the relevant Obligor’s Escrow Cash, and the denominator of which is the aggregate amount of Escrow Cash of all Obligors”; (b) in paragraph 6.2, the definition of “B” shall be amended to read “a fraction, the numerator of which is the aggregate number of the relevant Obligor’s Escrow Shares (and/or options over Large Escrow Shares as the case may be), and the denominator of which is the aggregate amount of Escrow Shares of all Obligors ( and including where applicable options to acquire Large Escrow Shares)”; (c) in paragraph 6.6, the words “percentage proportions set out in paragraph 2.1” shall be replaced with the words “manner described in the foregoing provisions of this paragraph 6”.3.2 Notwithstanding the terms of Schedule 9 to the Deed Poll, the parties agree that if the Effective Time does not occur on or prior to the Cut-off Time, then with effect from the Cut-off Time: (A) Loudeye shall continue to retain the Loudeye Shares issued by it prior to the date hereof that are currently being held by Loudeye as Escrow Shares (in the amounts set forth in column 3 of Schedule 1 hereto), and such Loudeye Shares shall continue to constitute Escrow Shares and shall be held subject to the terms and conditions of Schedule 9 to the Deed Poll; provided that if Loudeye receives written instructions from the Obligors that the amounts of such Escrow Shares being held in escrow are to be reallocated amongst the Obligors (subject to such instructions providing that the aggregate number of Loudeye 4 Shares to be held in escrow by Loudeye shall remain unchanged), then the parties shall take such actions as may be necessary (including the release by Loudeye of the applicable number of Escrow Shares to certain Obligors and the delivery to Loudeye of the applicable number of additional Loudeye Shares by other Obligors) to adjust the amounts of Loudeye Shares that are currently being held by Loudeye as Escrow Shares such that Loudeye retains from each Obligor the number of Loudeye Shares specified in such notice, and such Loudeye Shares shall continue to constitute Escrow Shares and shall be held subject to the terms and conditions of Schedule 9 to the Deed Poll; and (B) Loudeye shall continue to withhold an aggregate of 15% of any payments of cash or Loudeye Shares made pursuant to the Offer Document (including pursuant to any promissory note) that may be made in the future (the “Future Escrow Withholding Amount”) which amount shall be withheld from the payments to be made to the Obligors based on each Obligor’s Relevant Percentage; provided that if Loudeye receives written instructions from the Obligors that any Future Escrow Withholding Amount should be withheld from the Obligors in different proportions, Loudeye shall follow (and be entitled to rely on) such instructions (it being understood that any such instructions shall allocate the entire applicable Future Escrow Withholding Amount(s) to be withheld amongst the Obligors). (C) The following amendments shall be made to Schedule 9 to the Deed Poll: (a) in paragraph 6.1, the definition of “B” shall be amended to read “a fraction, the numerator of which is the aggregate amount of the relevant Obligor’s Escrow Cash, and the denominator of which is the aggregate amount of Escrow Cash of all Obligors”; (b) in paragraph 6.2, the definition of “B” shall be amended to read “a fraction, the numerator of which is the aggregate number of the relevant Obligor’s Escrow Shares (and/or Mike Large’s options over Loudeye Shares that Mike Large is obligated to deposit in escrow as the case may be), and the denominator of which is the aggregate amount of Escrow Shares of all Obligors (and including where applicable Mike Large’s options to acquire Loudeye Shares that Mike Large is obligated to deposit in escrow)”; (c) in paragraph 6.6, the words “percentage proportions set out in paragraph 2.1” shall be replaced with the words “manner described in the foregoing provisions of this paragraph 6”. This Clause 3.2 shall not become effective if the Effective Time occurs on or prior to the Cut-Off Time.3.3 For the avoidance of doubt, in the event of any discrepancy between the applicable terms of this Clause 3 and: (A) the terms of the Offer Document; (B) the terms of the Deed Poll; or (C) the terms of any Promissory Note, 5 the terms of this Clause 3 shall prevail in all respects irrespective of whether the Offer, Deed Poll or Promissory Notes contain any terms to the effect that the terms of such document are the whole agreement between the parties.4. Orderly Sales Provisions4.1 The parties agree that Schedule 13 of the Deed Poll (subject to the exempt disposals set out in paragraph 7 of Schedule 13) shall continue to apply to all Transfers of Loudeye Shares by the Obligors, except that if the Effective Time occurs, the table in paragraph 3 of Schedule 13 of the Deed Poll shall be replaced with the following table:

4.2 The parties agree that the definition of “AVERAGE DAILY TRADING PRICE” for the purposes of Schedule 13 of the Deed Poll shall be replaced with the following definition: “AVERAGE DAILY TRADING PRICE” means the average trading price of Loudeye Shares on NASDAQ for the Trading Day immediately prior to the Proposed Sale Date (determined by averaging the high and low price of the Loudeye Shares on such Trading Day).5.
