“ “Master Agreement” shall mean that certain Amended and Restated Master Agreement dated • July 2003 between Elan Corporation, plc., Elan Pharma International Limited, Elan International Services Limited, Elan, Monksland Holdings B.V. and Amarin.”

3.2. by the deletion of Section 3.01(c)(ii) in its entirety and the substitution therefor of the following:

“(ii) thereafter, subject to Clauses 5, 7 and 8 of the Master Agreement, at quarterly intervals (the first being three calendar months after the Purchase Closing), successive payments of Two Million Five Hundred Thousand Dollars ($2,500,000.00) until such time as the entire Total Divestiture Amount has been paid.”

3.3. by the insertion into Section 3.01 of the following new Section 3.01(dd):
