FORM OF PRIVATE PLACEMENT PURCHASE AGREEMENT

                     (the “Undersigned”), for itself and on behalf of the
beneficial owners listed on Exhibit A hereto (the “Accounts”) for whom the
Undersigned holds contractual and investment authority (each Account, as well as
the Undersigned if it is acquiring Purchased Notes (as defined below) hereunder,
a “Purchaser”), enters into this Private Placement Purchase Agreement (the
“Agreement”) with (a) Corsicanto II Designated Activity Company, a designated
activity company incorporated under the laws of Ireland (the “Company”) and the
wholly owned subsidiary of Amarin Corporation plc, a public limited company
incorporated under the laws of England and Wales (the “Guarantor”) and (b) the
Guarantor, on January 20, 2017 whereby the Purchaser will purchase (the
“Purchase”) the Company’s 3.50% Convertible Senior Notes due 2047, which are
guaranteed by the Guarantor (the “Notes”), that will be issued pursuant to the
provisions of an Indenture to be dated as of the Closing Date (as defined
herein) (the “Indenture”) in the form of Exhibit B hereto by and between the
Company and Wilmington Trust, National Association, as trustee (the “Trustee”).

On and subject to the terms and conditions set forth in this Agreement, the
parties hereto agree as follows:

Article I: Purchase of Notes

Subject to the terms set forth in this Agreement, at the Closing (as defined
herein), the Undersigned hereby agrees to cause the Purchasers to purchase from
the Company, and the Company hereby agrees to issue and sell to the Purchasers,
the principal amount of the Notes set forth in Exhibit A for the cash purchase
price specified in Exhibit A.

The closing of the Purchase (the “Closing”) shall occur on a date (the “Closing
Date”) which the parties intend to be January 25, 2017. At the Closing, (a) each
Purchaser shall deliver or cause to be delivered to the Company the Purchase
Price specified on Exhibit A hereto and (b) upon receipt of the Purchase
Price, the Company shall issue to each Purchaser the principal amount of Notes
specified on Exhibit A hereto (collectively, the “Purchased Notes”) (or, if
there are no Accounts, the Undersigned, as the sole Purchaser, shall deliver to
the Company the Purchase Price and upon receipt of the Purchase Price, the
Company shall deliver to the Undersigned the Purchased Notes); provided,
however, that the parties acknowledge that the delivery of the Purchased Notes
to the Purchaser may be delayed due to procedures and mechanics within the
system of the Depository Trust Company, Euroclear/CREST, the Irish Stock
Exchange plc or the NASDAQ Global Market (“NASDAQ”), or other events beyond the
Company’s control and that such delay will not be a default under this Agreement
so long as (i) the Company is using its reasonable best efforts to effect the
issuance of one or more global notes representing the Purchased Notes, (ii) such
delay is no longer than five business days, and (iii) interest shall accrue on
such Purchased Notes from January 25, 2017. Contemporaneously with or after the
Closing, the Company may issue Notes to one or more other investors, subject to
the terms of the Indenture. Lazard Frères & Co. LLC (“Lazard”) shall provide
instructions to the Undersigned for settlement of the Purchase. The delivery of
the Purchased Notes will be effected via DWAC. The Company’s wiring instructions
for delivery of the principal amount of Purchased Notes and DWAC settlement
instructions will be provided by Lazard post-pricing.

Article II: Covenants, Representations and Warranties of the Purchasers

The Undersigned hereby covenants as follows, and makes the following
representations and warranties on its own behalf and, where specified below, on
behalf of each Account, each of which is and shall be true and correct on the
date hereof and at the Closing, to the Company, the Guarantor and Lazard, and
all such covenants, representations and warranties shall survive the Closing.

--------------------------------------------------------------------------------

Section 2.1 Power and Authorization. Each of the Undersigned and each Purchaser
is duly organized, validly existing and in good standing under the laws of its
jurisdiction of formation, and the Undersigned has the power, authority and
capacity to execute and deliver this Agreement, to perform its obligations
hereunder, and to consummate the Purchase contemplated hereby, in each case on
behalf of itself and each Account. If the Undersigned is executing this
Agreement on behalf of Accounts, (a) the Undersigned has all requisite
discretionary and contractual authority to enter into this Agreement on behalf
of, and bind, each Account, and (b) Exhibit A hereto is a true, correct and
complete list of (i) the name of each Account and (ii) the principal amount of
Purchased Notes to be issued to such Account.

Section 2.2 Valid and Enforceable Agreement; No Violations. This Agreement has
been duly executed and delivered by the Undersigned and constitutes a valid and
legally binding obligation of the Undersigned and each Purchaser, enforceable
against the Undersigned and each such Purchaser in accordance with its terms,
except that such enforcement may be subject to (a) bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium or other similar laws affecting
or relating to enforcement of creditors’ rights generally, and (b) general
principles of equity, whether such enforceability is considered in a proceeding
at law or in equity (the “Enforceability Exceptions”). This Agreement and
consummation of the Purchase will not violate, conflict with or result in a
breach of or default under (i) the Undersigned’s or such Purchaser’s
organizational documents, (ii) any agreement or instrument to which the
Undersigned or such Purchaser is a party or by which the Undersigned or such
Purchaser or any of their respective assets are bound, or (iii) any laws,
regulations or governmental or judicial decrees, injunctions or orders
applicable to the Undersigned or such Purchaser.

Section 2.3 Qualified Institutional Buyer. Each Purchaser is a “qualified
institutional buyer” within the meaning of Rule 144A promulgated under the
Securities Act.

Section 2.4 No Affiliates. No Purchaser is, or has been at any time during the
consecutive three-month period preceding the date hereof, a director, officer or
“affiliate” within the meaning of Rule 144 promulgated under the Securities Act
(an “Affiliate”) of the Company or the Guarantor.

Section 2.5 Restricted Notes, American Depository Shares and Shares. Each
Purchaser (a) acknowledges that the issuance of the Purchased Notes pursuant to
the Purchase and the issuance of any American Depository Shares of the Guarantor
(the “Conversion ADSs”), each representing one ordinary share, 50 pence par
value per share, of the Guarantor (the “Conversion Shares”), upon conversion of
any of the Purchased Notes (the Conversion ADSs and the Conversion Shares,
together, the “Conversion Securities”) have not been registered or qualified
under the Securities Act or any state securities laws, and the Purchased Notes
and Conversion Securities are being offered and sold in reliance upon exemptions
provided in the Securities Act and state securities laws for transactions not
involving any public offering and, therefore, cannot be sold, transferred,
offered for sale, pledged, hypothecated or otherwise disposed of unless they are
subsequently registered and qualified under the Securities Act and applicable
state laws or unless an exemption from such registration and qualification is
available, and that evidence of the Purchased Notes and Conversion Securities
will bear a legend to such effect as specified in the Indenture, and (b) is
purchasing the Purchased Notes and Conversion Securities for investment purposes
only for the account of such Purchaser and not with any view toward a
distribution thereof or with any intention of selling, distributing or otherwise
disposing of the Purchased Notes or Conversion Securities in a manner that would
violate the registration requirements of the Securities Act. The Undersigned and
each Purchaser confirms to the Company and Lazard that it has such knowledge and
experience in business matters that the Undersigned and each such Purchaser is
capable of evaluating the merits and risks of an investment in the Purchased
Notes or the Conversion Securities and of making an informed investment decision
and understands that (x) this investment is suitable only for an investor which
is able to bear the economic consequences of losing its entire investment and
(y) the purchase of the Purchased Notes or the Conversion Securities by the
Undersigned and each Purchaser is a speculative investment which involves a high
degree of risk of loss of the entire investment.

--------------------------------------------------------------------------------

Section 2.6 No Illegal Transactions. Each of the Undersigned and each Purchaser
has not, directly or indirectly, and no person acting on behalf of or pursuant
to any understanding with it has, disclosed to a third party any information
regarding the Purchase nor engaged in any transactions in the securities of the
Company or the Guarantor (including, without limitation, any Short Sales (as
defined below) involving any of the Company’s or the Guarantor’s securities)
since the time that the Undersigned was first contacted by any of the Company,
the Guarantor, Lazard or any other person regarding the Purchase, this Agreement
or an investment in the Purchased Notes or the Company or the Guarantor. Each of
the Undersigned and such Purchaser covenants that neither it nor any person
acting on its behalf or pursuant to any understanding with it will disclose to a
third party any information regarding the Purchase or engage, directly or
indirectly, in any transactions in the securities of the Company or the
Guarantor (including Short Sales) prior to the time the transactions

Purchaser’s compliance with their respective obligations under the U.S. federal
securities laws and the Undersigned’s and such Purchaser’s respective internal

include any employees, subsidiaries, desks, groups or affiliates of the
Undersigned or such Purchaser that are effectively walled off by appropriate
“Fire Wall” information barriers approved by the Undersigned’s or the
Purchaser’s respective legal or compliance department (and thus such walled off
parties have not been privy to any information concerning the Purchase), and
(b) the foregoing representations and covenants of this Section 2.6 shall not
apply to any transaction by or on behalf of an Account, desk or group that was
effected without the advice or participation of, or such Account’s, desk’s or
group’s receipt of information regarding the Purchase provided by, the
Undersigned.

Section 2.7 Adequate Information; No Reliance. The Undersigned acknowledges and
agrees on behalf of itself and each Purchaser that (a) the Undersigned has been

Lazard, except for (i) the publicly available filings and submissions made by
the Guarantor with the SEC under the Exchange Act and (ii) the representations
and warranties made by the Company and the Guarantor in this Agreement.

Section 2.8 No Public Market. Each Purchaser understands that no public market
exists for the Purchased Notes, and that there is no assurance that a public
market will ever develop for the Purchased Notes.

Section 2.9 Subsequent Offers and Resales of the Purchased Notes in Ireland.
Each Purchaser agrees that:
