Item 6.	Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

	*Board of Directors* Michele Ollier and Francesco De Rubertis (the “Index Directors”) were elected as directors of the Issuer pursuant to an investor rights agreement that the Issuer entered into with certain holders of its securities, including the Reporting Persons. The rights to be appointed to the Issuer’s board of directors pursuant to the investor rights agreement terminated upon the closing of this offering and there is no further contractual obligations regarding the election of the Issuer’s directors. Each Index Director will continue to hold office until his successor has been elected and qualified or until the earlier of his resignation or removal. *Lock-Up Agreement* The Index Funds, certain other stockholders and each director and officer of the Issuer agreed with Jefferies LLC (the “Underwriter”), pursuant to a lock-up agreement (each, a “Lock-Up Agreement”), for the period beginning on the date of such Lock-Up Agreement and continuing through the close of trading on the date that is 180 days after June 30, 2014, subject to certain exceptions, not to offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of or announce the intention to otherwise dispose of, or enter into any swap, hedge or similar agreement or arrangement that transfers, in whole or in part, the economic risk of ownership of, directly or indirectly, engage in any short selling of any common stock or securities convertible into or exchangeable or exercisable for any common stock, whether currently owned or subsequently acquired, without the prior written consent of the Underwriter, for a period of 180 days from the date of effectiveness of the offering. *Investors’ Rights Agreement* The Index Funds and certain other stockholders (collectively, the “Holders”) of the Issuer have entered into an Investors’ Rights Agreement, dated August 29, 2007, as amended on December 20, 2013 (the “Investors’ Rights Agreement”), with the Issuer. With the closing of the IPO, holders of a total of 8,220,870 shares of our common stock as of March 31, 2014, including for this purpose 351,595 shares of common stock issued upon the conversion of the Notes and accrued interest thereon immediately prior to the closing of the IPO have the right to require the Issuer to register these shares (“Registrable Shares”) under the Securities Act under specified circumstances and will have incidental registration rights as described below. After registration pursuant to these rights, these shares will become freely tradable without restriction under the Securities Act. . Demand Registration Rights At any time after 180 days after the closing of this offering, the holders of a majority of the Registrable

Shares may request that we register all or a portion of their common stock for sale under the Securities Act so long as the total amount of Registrable Shares registered has an anticipated aggregate offering price of less than $10.0 million. The Issuer will effect the registration as requested, unless in the good faith judgment of the Issuer’s Board of Directors, such registration would be seriously detrimental to the Issuer and its stockholders and should be delayed. The Issuer is not obligated to file a registration statement pursuant to these demand provisions on more than two occasions. In addition, when the Issuer is eligible for the use of Form S-3, or any successor form, holders of a majority of the shares having demand registration rights may make up to two requests within any 12-month period that the Issuer register all or a portion of their common stock for sale under the Securities Act on Form S-3, or any successor form.

Piggyback Registration Rights

In addition, if at any time the Issuer registers any shares of its common stock, the holders of all shares having registration rights are entitled to at least 30 days notice of the registration and to include all or a portion of their common stock in the registration. With respect to the IPO, the registration rights have been validly waived.

In the event that any registration in which the holders of Registrable Shares participate pursuant to the registration rights agreement is an underwritten public offering, the number of Registrable Shares to be included may, in specified circumstances, be limited due to market conditions.

Expenses of Registration

The Issuer will pay all registration expenses (other than underwriting discounts and selling commissions) and the reasonable fees and expenses of a single special counsel for the selling stockholders, related to any demand or piggyback registration.

Indemnification

The registration rights agreement contains customary cross-indemnification provisions, pursuant to which the Issuer is obligated to indemnify the selling stockholders in the event of material misstatements or omissions in the registration statement attributable to the Issuer, and the selling stockholders are obligated to indemnify the Issuer for material misstatements or omissions in the registration statement attributable to them. The demand and piggyback registration rights described above will expire three years after our initial public offering or, with respect to any particular stockholder, when that stockholder can sell all of its shares under Rule 144 of the Securities Act.

Termination

Shares of Common Stock cease to be Registrable Securities under the Investors’ Rights Agreement, and a stockholder party’s ability to initiate a registration or exercise its piggyback registration rights terminates, upon the earlier of:

· The fifth anniversary of the closing of the IPO; and

· with respect to any Holder, the earlier of such time that the Holder is able to sell all of its Registrable Securities pursuant to Rule 144(k) under the Securities Act.
