Explanatory Note

This Amendment No. 6 is being filed for the purpose of re-filing Exhibit 5.1, Exhibit 8.2 (included in Exhibit 5.1) and Exhibit 23.2 (included in Exhibit 5.1). No changes or additions are being made hereby to the Prospectus constituting Part I of the Registration Statement (not included herein) or to Part II of the Registration Statement.

PART II

Information not required in prospectus

Item 13. Other expenses of issuance and distribution.

The following table sets forth the fees and expenses, other than underwriting discounts and commissions, payable in connection with the registration of the ordinary shares hereunder. All amounts are estimates except the SEC registration fee.

Item 14. Indemnification of directors and officers.

To the fullest extent permitted by Irish law, our amended and restated articles of association (which we will adopt substantially in the form attached as Exhibit 3.2 to the registration statement prior to the closing of this offering) confer an indemnity on our directors and officers. However, this indemnity is limited by the Irish Companies Acts, which prescribe that an advance commitment to indemnify only permits a company to pay the costs or discharge the liability of a director or corporate secretary where judgment is given in favor of the director or corporate secretary in any civil or criminal action in respect of such costs or liability, or where an Irish court grants relief because the director or corporate secretary acted honestly and reasonably and ought fairly to be excused. Any provision whereby an Irish company seeks to commit in advance to indemnify its directors or corporate secretary over and above the limitations imposed by the Irish Companies Acts will be void under Irish law, whether contained in its articles of association or any contract between the company and the director or corporate secretary. This restriction does not apply to our executives who are not directors, the corporate secretary or other persons who would be considered “officers” within the meaning of that term under the Irish Companies Acts.

Our amended and restated articles of association also contain indemnification and expense advancement provisions for persons who are not directors or our corporate secretary.

We are permitted under our amended and restated articles of association and the Irish Companies Acts to take out directors’ and officers’ liability insurance, as well as other types of insurance, for our directors, officers, employees and agents.

Additionally, our wholly-owned subsidiary, Globoforce, Inc., is incorporated under the laws of the Commonwealth of Massachusetts. All of our directors are also directors of Globoforce, Inc. Sections 8.51 and 8.56 of the Massachusetts Business Corporation Act provide that a Massachusetts corporation may

II-1

indemnify any persons who are parties to any proceeding by reason of the fact that such person was a director or officer of such corporation. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such proceeding, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was illegal. Where an officer or director is wholly successful on the merits or otherwise in the defense of any proceeding referred to above, the corporation must indemnify him or her against reasonable expenses which such officer or director has incurred in connection with the proceeding.

Our wholly-owned subsidiary, Globoforce, Inc., will enter into agreements to indemnify each of our directors and executive officers to the maximum extent allowed under Massachusetts law. These agreements will, among other things, indemnify these individuals for certain expenses (including attorneys’ fees), judgments, fines and settlement amounts reasonably incurred by such person in any action or proceeding, including any action by or in our right, on account of any services undertaken by such person on behalf of the Company or that person’s status as one of our directors or executive officers.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 15. Recent sales of unregistered securities.

In the three years preceding the filing of this registration statement, the registrant has issued the following securities that were not registered under the Securities Act. The following share numbers reflect the 5-for-1 split of our ordinary shares and redeemable convertible preferred shares effected on March 3, 2014:

Grants and exercises of options

Since January 1, 2010, we have granted share options to purchase 823,215 ordinary shares with exercise prices ranging from €0.83 to €4.77 per share, or $1.17 to $6.18 per share based on the exchange rate on the date of grant, to employees, directors and consultants pursuant to our share option plans. All of these options were issued in consideration of services rendered to us, with exercise prices equal to the estimated fair value of our ordinary shares on the date of grant. No cash or additional consideration was received by us in consideration of our issuance of these options.

Since January 1, 2010, we have sold 378,045 ordinary shares to employees upon the exercise of share options. We received cash consideration in the aggregate amount of $35,281 for 92,000 of these ordinary shares. The remaining 286,045 ordinary share were issued pursuant to net exercise arrangements of 508,000 share options that had an average exercise price of $0.29 per share, and we received cash consideration in the aggregate amount of $4,615 and retained 221,955 shares to cover employees’ aggregate exercise price and minimum tax withholding obligation, which was then paid by us on the employees’ behalf in the aggregate amount of $3.2 million.

Since January 1, 2010, we sold 87,500 preferred shares to a warrant holder for cash consideration in the aggregate amount of $133,350 upon the exercise of a preferred stock warrant.

The issuance of the options, ordinary shares and preferred shares referenced above were exempt either pursuant to Rule 701, as a transaction pursuant to a compensatory benefit plan, or pursuant to Section 4(a)(2), as a transaction by an issuer not involving a public offering.

(b) Consolidated Financial Statements Schedules:

Item 17. Undertakings.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, or the Act, may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The Registrant hereby undertakes that:
