PROPOSAL NO. 3
ADOPTION OF NEW ARTICLES OF ASSOCIATION

Background

The purpose of Proposal 3 is to ensure that the Company is governed by articles of association which better reflects up-to-date market standard provisions for an Irish public limited company with its shares listed on Nasdaq.

For the purposes of this section, the Company’s existing articles of association are referred to as the “Existing Articles” and the articles of association proposed to be adopted at the Meeting are referred to as the “New Articles”.

The following description of the differences between the Existing Articles and the New Articles is only a summary of certain matters and does not constitute a conclusive description of the differences between the provisions of the Existing Articles and the New Articles. This summary is qualified in its entirety by reference to the complete text of the New Articles, which is attached to this circular as Appendix A. We strongly urge you to read Appendix A in its entirety before casting your vote.

Shareholders should note in particular the following differences between certain of the provisions of the Existing Articles and the New Articles:

Finally, it should also be noted that the adoption of the New Articles will also have the effect of restarting the Board’s five-year allotment authority in respect of the entire authorised but unissued share capital in the Company.

PROPOSAL NO. 4
REVERSE SHARE SPLIT

Background

The purpose of Proposal 4 is to give the Board authority, upon its determination and at its sole discretion, to implement the Reverse Share Split. The Board is seeking approval for the Reverse Share Split with the primary purpose of increasing the per share market price of the shares in the Company in order to continue to meet the price criteria for continued listing on Nasdaq, namely the requirement pursuant to Nasdaq Listing Rule 5550(a)(2) to maintain a minimum bid price of $1.00 per share (the “Bid Price Rule”).

A deficiency by the Company in complying with the Bid Price Rule could lead to a determination from Nasdaq that the Company’s shares are subject to delisting; in the event the Company’s shares are delisted from Nasdaq, the only established trading market for the Company’s shares would be eliminated and the Company would be forced to list its shares on the OTC Markets or another quotation medium, depending on its ability to meet the specific listing requirements of those quotation systems.

Even if the Company continues to maintain compliance with the Bid Price Rule, the Board may still determine to implement the Reverse Share Split if it considers that it would be in the interests of the Company to do so. In addition to helping maintain compliance with the Bid Price Rule, the Board is of the belief that, if the Reverse Share Split is implemented, the expected increase in the market price per share could encourage investor interest and improve the marketability of the Company’s shares to a broader range of investors, and thus enhance the Company’s liquidity. However, there can be no assurance that, if the Reverse Share Split is implemented, (i) the market price per share of the Company’s shares after the Reverse Share Split will rise in proportion to the reduction in the number of the Company’s shares outstanding resulting from the Reverse Share Split, (ii) the market price per post-Reverse Share Split share will remain in excess of the $1.00 minimum bid price for a sustained period of time, or (iii) the Reverse Share Split will result in a per share price that would attract a broader range of investors.

Details of the Proposed Reverse Share Split

The Board proposes to consolidate the Company’s issued share capital as follows:

Each shareholder’s proportionate ownership in the Company will remain unchanged, except for adjustments that may result from the treatment of fractional entitlements to shares. No shares shall be issued with respect to fractional entitlements to shares arising from the Reverse Share Split. Upon approval of the Reverse Share Split, all fractional entitlements to shares will be combined, aggregated and then sold in the market. The net sale proceeds from these aggregated shares will be retained for the benefit of the Company.

Effect on Outstanding Derivative Securities

The Reverse Share Split will require that proportionate adjustments be made to the per share exercise or conversion (as applicable) price and the number of shares issuable upon the vesting, exercise or conversion (as applicable) of the Company’s outstanding derivative securities issued or reserved for future issuance by the Company (pursuant to the terms of such derivative securities), in accordance with the approved share split ratio. The adjustment to such derivative securities (pursuant to the terms of such derivative securities), as required by the Reverse Share Split and in accordance with the approved share split ratio, would result in approximately the same aggregate price being required to be paid under such derivative securities upon exercise or conversion (as applicable) thereof, and approximately the same value of shares being delivered upon such exercise or conversion (as applicable), immediately following the Reverse Share Split as was the case immediately preceding the Reverse Share Split.

Vote Required

As an ordinary resolution, Resolution No. 4 requires votes in favour representing a simple majority of the votes cast (in person or by proxy) at the Extraordinary General Meeting in order to be passed.

Recommendation of the Board

The Board recommends a vote FOR the approval of Resolution No. 4.

PROPOSAL NO. 5
AMENDMENT OF MEMORANDUM OF ASSOCIATION

Background

The purpose of Proposal 5 is to ensure that the objects of the Company accurately reflect changes to the share capital arising from the Reverse Share Split if implemented by the Board.

Vote Required

As a special resolution, Resolution No. 5 requires votes in favour representing not less than 75% of the votes cast (in person or by proxy) at the Extraordinary General Meeting in order to be passed.

Recommendation of the Board

The Board recommends a vote FOR the approval of Resolution No. 5.

PROPOSAL NO. 6
ADOPTION OF NEW ARTICLES OF ASSOCIATION

Background

The purpose of Proposal 6 is to ensure that the Company is governed by articles of association which gives effect to the Reverse Share Split if implemented by the Board.
