Explanatory Note

This Amendment No. 4 (this “Amendment”) amends and supplements the Schedule 13D filed by the Reporting Persons (as defined in the Schedule 13D) with the Securities and Exchange Commission (“SEC”) on October 26, 2009, as amended by Amendment No. 1 to the Schedule 13D (“Amendment No. 1”) filed by the Reporting Persons with the SEC on December 23, 2010, Amendment No. 2 to the Schedule 13D (“Amendment No. 2”), filed by the Reporting Persons with the SEC on January 21, 2011, and Amendment No. 3 to the Schedule 13D (“Amendment No. 3”) filed by the Reporting Persons with the SEC on March 16, 2011 (such Schedule 13D, as amended by Amendment No. 1, Amendment No. 2 and Amendment No. 3, the “Schedule 13D”).  The Schedule 13D, as amended by this Amendment, relates to the ordinary shares, 50 pence par value per share (the “Ordinary Shares”), of Amarin Corporation plc (the “Issuer”), each Ordinary Share represented by one American Depositary Share (each, an “ADS” and, collectively, the “ADSs”).  Except as specifically provided herein, this Amendment does not modify or amend any of the information previously reported in the Schedule 13D.  Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to such terms in the Schedule 13D.


Item 4.                      Purpose of Transaction
 
Item 4 of the Schedule 13D is hereby amended by deleting it in its entirety and substituting the following in lieu thereof:

The Reporting Persons acquired the securities reported herein for investment in the ordinary course of business because of their belief that the Issuer represents an attractive investment based on the Issuer’s business prospects and strategy.  The Reporting Persons reserve the right to acquire, or cause to be acquired, additional securities of the Issuer, to dispose of, or cause to be disposed, such securities at any time or to formulate other purposes, plans or proposals regarding the Issuer or any of its securities, to the extent deemed advisable in light of general investment and trading policies of the Reporting Persons, market conditions or other factors.  Except as set forth herein, the Report Persons do not have any plan or proposal that would relate to, or result in, any of the matters set forth under subsections (a) through (j) of Item 4 of Schedule 13D.

Pursuant to the Securities Purchase Agreement, (i) the Issuer issued and sold to the Abingworth Funds, and the Abingworth Funds purchased from the Issuer, at the Closing, 17,000,000 Ordinary Shares, each Ordinary Share represented by one ADS, and Warrants to purchase up to an aggregate of 8,500,000 Ordinary Shares and (ii) the Issuer issued and sold to the Other Purchasers, and the Other Purchasers purchased from the Issuer, at the Closing, 53,399,996 Ordinary Shares, each Ordinary Share represented by one ADS, and Warrants to purchase up to an aggregate of 26,699,996 Ordinary Shares (the transactions specified in clauses (i) and (ii) above are referred to herein collectively as the “Private Placement”).  Each Abingworth Fund was prohibited from exercising the Warrants purchased by it, to the extent that after giving effect to such exercise, such Abingworth Fund (together with its affiliates) would beneficially own in excess of 9.99% of the Ordinary Shares outstanding immediately after giving effect to such exercise; provided that such Abingworth Fund may increase or decrease such percentage to any other percentage (or waive the applicability of the ownership “blocker” provision) upon written notice to the Issuer; provided, further, that any such increase (or waiver) would not be effective until the sixty-first (61st) day after such notice is delivered to the Issuer.  On April 28, 2011, Abingworth notified the Issuer that it desired to waive the applicability of the blocker provision described above with respect to all of the Warrants held by each of the Abingworth Funds, as permitted under the Warrants.  The waiver will become effective 61 days from the date of such notice, and, thus, all of the Warrants will become exercisable beginning on June 28, 2011.

The Securities Purchase Agreement contains a right of first refusal in favor of each Purchaser to purchase up to such Purchaser’s Pro Rata Percentage (as defined in the Securities Purchase Agreement) of any offering (an “Equity Offering”) by the Issuer of Ordinary Shares or any other class or series of its capital stock, or any other securities convertible or exercisable into or exchangeable for Ordinary Shares or any other class or series of capital stock, subject to certain exceptions as set forth in the Securities Purchase Agreement.  To the extent any Other Purchaser elects not to exercise its right of first refusal to purchase its full Pro Rata Percentage of any Equity Offering, the Abingworth Funds shall have the first right of refusal to subscribe for and purchase any securities not subscribed for by any such Other Purchaser.   The right of first refusal shall terminate with respect to a Purchaser (counting such Purchaser and its affiliates purchasing Ordinary Shares under the Securities Purchase Agreement as one Purchaser) at such time as such Purchaser (together with its affiliates) ceases to collectively own at least fifty percent (50%) of the Ordinary Shares purchased by such Purchaser and its affiliates at the Closing.

Under the terms of the Securities Purchase Agreement, the Issuer agreed to (i) prepare and file (as soon as reasonably practicable, but in no event later than sixty (60) days after the Closing (the “Filing Deadline Date”)) with the Securities and Exchange Commission (the “SEC”) a registration statement to register the resale of the Ordinary Shares issued in the Private Placement (including the Ordinary Shares issuable upon exercise of the Warrants issued in the Private Placement) and (ii) use its commercially reasonable efforts to cause the Registration Statement to be declared effective by the SEC no later than 90 days (120 days in the event the registration statement is reviewed by the SEC) after the earlier of (i) the initial filing of the registration statement or (ii) the Filing Deadline Date.  The Issuer will be liable for certain penalties set forth in the Securities Purchase Agreement for the failure to meet such filing and effective date deadlines.  The Purchasers also received certain “piggy-back” registration rights covering the Ordinary Shares issued in the Private Placement (including the Ordinary Shares issuable upon exercise of the Warrants sold in the Private Placement).

In connection with the transactions contemplated by the Securities Purchase Agreement, the Abingworth Funds entered into a Management Rights Agreement with the Issuer and certain of the Other Purchasers, whereby (i) the Abingworth Funds will have the right to nominate one designee for election to the Issuer’s Board of Directors (“Board”) for so long as the Abingworth Funds (together with their respective affiliates) beneficially own at least five percent (5%) of the issued and outstanding Ordinary Shares of the Issuer, (ii) each Lead Investor (as defined in the Management Rights Agreement) will individually have the right to nominate one designee for election to the Board so long as such Lead Investor beneficially owns the number of Ordinary Shares equal to at least fifty percent (50%) of the number of Ordinary Shares it purchased in the Private Placement, (iii) the Lead Investors will have the right to collectively nominate two (2) other individuals to the Board so long as the Lead Investors, collectively as a group, beneficially own in the aggregate at least twenty-five percent (25%) of the issued and outstanding Ordinary Shares of the Issuer and (iv) the parties to the Management Rights Agreement agreed to vote their Ordinary Shares in favor of the director designees specified in the foregoing clauses (i), (ii) and (iii).

By virtue of the terms of the Management Rights Agreement, the Reporting Persons and the Other Purchasers party to the Management Rights Agreement may be deemed to constitute a “group” within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended.  The Reporting Persons and the Other Purchasers party to the Management Rights Agreement are not acting as a “group”, and the Reporting Persons disclaim beneficial ownership of, and any pecuniary interest in, all of the Ordinary Shares beneficially owned by the Other Purchasers party to the Management Rights Agreement.

The foregoing descriptions of the Securities Purchase Agreement, the Warrants and the Management Rights Agreement do not purport to be complete and are qualified in their entirety by the terms of such document which are incorporated herein by reference in response to this Item 4 and which, (i) in the case of the Securities Purchase Agreement and the Form of Warrant, have been filed as exhibits to the Issuer’s Annual Report on Form 20-F for the fiscal year ended December 31, 2008, filed with the SEC on October 22, 2009, and (ii) in the case of the Management Rights Agreement, has been filed as an exhibit to this Schedule 13D.

As described in Item 3 of this Schedule 13D, Mr. Anderson, as the Abingworth Funds’ designee to the Board, was awarded an aggregate of 120,000 Options on the Grant Date in consideration of his services as a director of the Issuer.  The Options were issued under the Plan and have an exercise price of $1.03 per share, provided that such per-share exercise price shall not be less than the par value of an Ordinary Share at any time (currently, 50 pence).  The Options initially were scheduled to vest in four equal increments of twenty-five percent (25%) per year beginning on the one-year anniversary of the Grant Date (or February 10, 2011), such that 30,000 Options would vest on each of the first, second, third and fourth anniversaries of the Grant Date.  However, in light of the Issuer’s announcement of favorable data from its MARINE trial for AMR101, the Board unanimously approved the acceleration of the vesting schedule relating to certain options (including the Options) granted by the Issuer, so that all of the vesting dates described above have been accelerated by a period of six months.

Pursuant to an agreement among Mr. Anderson and Abingworth, Mr. Anderson is permitted to retain 16,800 of the Options (such 16,800 Options, the “Anderson Options”), and Mr. Anderson has voting and dispositive power over the Anderson Options.  Mr. Anderson is deemed to hold the remaining 103,200 Options for the benefit of the Abingworth Funds (collectively, the “Abingworth Options”).  Of the Abingworth Options, (i) 51,600 Options are held by Mr. Anderson for the benefit of ABV V and (ii) 51,600 Options are held by Mr. Anderson for the benefit of AGE.  Mr. Anderson must exercise, vote or dispose of all of the Abingworth Options solely pursuant to the direction of Abingworth, and to the extent that any of the Abingworth Options are vested, ABV V or ABE, as applicable, is entitled to the Ordinary Shares issuable upon exercise of those Abingworth Options.  Since the Options vest on an annual basis, vested Options will be allocated amongst Mr. Anderson, ABV V and ABE on a pro rata basis.  For example, with respect to the first tranche of 30,000 Options which already has vested, (x) 12,900 Options have been allocated to ABV V, (y) 12,900 Options have been allocated to AGE, and (z) 4,200 Options have been allocated to Mr. Anderson.

In addition, on December 10, 2010, certain of the Reporting Persons entered into pre-arranged stock trading plans (the “Initial Trading Plans” and each, an “Initial Trading Plan”) to sell Ordinary Shares of the Issuer.  Each Initial Trading Plan was designed to comply with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and provided for the sale, over a period of approximately one year, of up to (i) 3,750,000 Ordinary Shares held by ABV V, (ii) 3,750,000 Ordinary Shares held by AGE, and (iii) 1,000,000 Ordinary Shares held by ABE.  All sales of Ordinary Shares under the Initial Trading Plans were to be made in the broker’s discretion.  Copies of the Initial Trading Plans have been filed as Exhibits 5, 6 and 7 to this Schedule 13D.  As a result of the Lock-Up Agreement entered into in connection with the Offering described below, the Reporting Persons amended each of the Trading Plans to provide, among other things, for the suspension of each of the Trading Plans during the Lock-Up Period, and that any trades under the Trading Plans only could be effected during the period beginning on the first day following the expiration of the Lock-Up Period through and including December 10, 2011 (as so amended, the “Amended Trading Plans”).  Copies of the Amended Trading Plans have been filed as Exhibits 9, 10 and 11 to this Schedule 13D.  Abingworth subsequently terminated the Amended Trading Plans on February 25, 2011, and on March 9, 2011, ABV V, AGE and ABE each entered into a new pre-arranged stock trading plan (the “New Trading Plans” and each, a “New Trading Plan”) to sell Ordinary Shares of the Issuer.  As with the Initial Trading Plans, each New Trading Plan was designed to comply with Rule 10b5-1 under the Exchange Act, and all sales of Ordinary Shares under the New Trading Plans were to be made in the broker’s discretion.  The New Trading Plans provided for the sale, over a period of approximately one year, of up to (i) 3,750,000 Ordinary Shares held by ABV V, (ii) 3,750,000 Ordinary Shares held by AGE, and (iii) 1,000,000 Ordinary Shares held by ABE.  Under the New Trading Plans, on April 18, 2011, ABV V sold an aggregate of 1,843,016 Ordinary Shares, AGE sold an aggregate of 1,843,016 Ordinary Shares, and ABE sold an aggregate of 493,142 Ordinary Shares.  The Abingworth Funds terminated the Trading Plans as of April 18, 2011, following the trades described in the preceding sentence.  Copies of the New Trading Plans have been filed as Exhibits 12, 13 and 14 to this Schedule 13D.

As mentioned above, on January 6, 2011, the Issuer entered into an underwriting agreement (the “Underwriting Agreement”) with Jefferies & Company, Inc. and Leerink Swann LLC, acting as joint book-running managers and as representatives of the several underwriters named therein (collectively, the “Underwriters”), pursuant to which the underwriters agreed to purchase, and the Issuer agreed to sell, an aggregate of 12,000,000 ADSs at a price to the public of $7.60 per share ($7.296 per share, net of underwriting discounts and commissions) (the “Offering”).  Pursuant to the Underwriting Agreement, the Issuer also granted to the Underwriters a 30-day option to purchase up to an additional 1,800,000 ADSs to cover over-allotments, if any, at the same price, which the Underwriters exercised on January 6, 2011.  The Offering closed on January 11, 2011.  In connection with the Offering, the Abingworth Funds entered into a lock-up agreement (the “Lock-Up Agreement”) running in favor of the Underwriters with regard to future sales of the Issuer’s ADSs and Ordinary Shares and other securities exercisable or exchangeable for ADSs or Ordinary Shares for a period of 45 days after the date of the Prospectus Supplement (File No. 333-170505) dated January 6, 2011, filed pursuant to Rule 424(b)(5) under the Securities Act (the “Prospectus Supplement”), pursuant to which the Offering was made.  The description of the Lock-Up Agreement is qualified in its entirety by reference to the terms of the Lock-Up Agreement, a copy of which has been filed as Exhibit 8 to this Schedule 13D.
