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

Director Nomination Agreement

In connection with the Issuers initial public offering, the Record Holders have entered into a Director Nomination Agreement with the Issuer (the Director Nomination Agreement) that provides the Record Holders the right to designate nominees for election to the Issuers Board of Directors so long as Reporting Persons beneficially own 5% or more of the total number of shares that it owns as of the completion of the Issuers initial public offering (the Original Perceptive Shares).

The Director Nomination Agreement provides the Record Holders the right to designate: (i) a number of directors equal to 66% of the total directors (rounded up to the nearest whole number) for so long as the Reporting Persons beneficially own 75% or more of the Original Perceptive Shares; (ii) a number of directors equal to 55% of the total directors (rounded up to the nearest whole number) for so long as the Reporting Persons beneficially own at least 50% and less than 75% of the Original Perceptive Shares; (iii) a number of directors equal to 40% of the total directors (rounded up to the nearest whole number) for so long as the Reporting Persons beneficially own at least 25% and less than 50% of the Original Perceptive Shares; (iv) a number of directors equal to 25% of the total directors (rounded up to the nearest whole number) for so long as the Reporting Persons beneficially own at least 10% and less than 25% of the Original Perceptive Shares, and (v) one director for so long as the Reporting Persons beneficially own at least 5% of the Original Perceptive Shares. In each case, the nominees designated by the Record Holders must comply with applicable law and Nasdaq listing rules. In addition, the Record Holders shall be entitled to nominate the Chairman of the board of directors so long as the Reporting Persons own more than 5% of the Original Perceptive Shares. The Director Nomination Agreement will terminate at such time as Reporting Persons own less than 5% of the Original Perceptive Shares.

The foregoing summary of the Director Nomination Agreement does not purport to be complete and is qualified in its entirety by reference to the Director Nomination Agreement which is filed as Exhibit 2 hereto and incorporated by reference herein.

Shareholders Agreement

The Record Holders are party to a Shareholders Agreement with the Issuer. The Shareholders Agreement grants the parties thereto certain registration rights in respect of the registrable securities held by them, which securities include (a) the Ordinary Shares issued or issuable by holders of shares of the Issuers convertible preferred shares; (b) any Ordinary Shares issued or issuable upon conversion or exercise of any other of the Issuers other securities; (c) any Ordinary Shares issued or issuable as a dividend or other distribution with respect to, in exchange for or in replacement of the securities referenced in (a); and (d) with respect solely to the piggyback registration rights described below, the issued Ordinary Shares. The registration of Ordinary Shares pursuant to the exercise of these registration rights would enable the holders thereof to sell such shares without restriction under the Securities Act of 1933, as amended (the Securities Act), when the applicable registration statement is declared effective. Under the Shareholders Agreement, the Issuer will pay all expenses relating to such registrations, including the fees of one special counsel for the participating holders, and the holders will pay all underwriting discounts and commissions relating to the sale of their shares. The Shareholders Agreement also includes customary indemnification and procedural terms.

These registration rights will expire, with respect to any holder of registrable securities, at such time at which such shareholder can sell all of the Ordinary Shares held by it pursuant to Rule 144 of the Securities Act in any ninety-day period.

Demand registration rights

At any time beginning six months after the closing of the Issuers initial public offering, the holders under the Shareholders Agreement of not less than 40% of the voting power of the registrable securities then outstanding may request that the Issuer prepare, file and maintain a registration statement on Form S-1 to register all or part of their registrable securities (subject to a limitation of the Issuer only being obligated to consummate no more than two registrations pursuant to this right). Once the Issuer is eligible to use a registration statement on Form S-3, the holders under the Shareholders Agreement of at least 30% of the registrable securities then outstanding may request that the Issuer prepare, file and maintain a registration statement on Form S-3 in any jurisdiction in which the Issuer has had an underwriting public offering, but only if the aggregate offering amount of the registrable securities requested to be registered would exceed $5 million.

Piggyback registration rights

In the event that the Issuer proposes to register any of its securities under the Securities Act, either for its own account or for the account of other security holders, the shareholders party to the Shareholders Agreement will be entitled to certain piggyback registration rights allowing them to include their registrable securities in such registration, subject to certain marketing and other limitations. As a result, whenever the Issuer propose to file a registration statement under the Securities Act other than with respect to a demand registration or a registration statement on Form S-4 or S-8, these holders will be entitled to notice of the registration and will have the right to include their registrable securities in the registration subject to certain limitations.

The foregoing summary of the Shareholders Agreement does not purport to be complete and is qualified in its entirety by reference to the Shareholders Agreement which is filed as Exhibit 3 hereto and incorporated by reference herein.

Lock-up Agreement
