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

Lock Up Agreement

In connection with the initial public offering of the Issuer, KKR Biosimilar entered into a lock-up agreement and agreed with the underwriters, subject to certain exceptions, not to dispose of or hedge any shares of Common Stock or securities convertible into or exchangeable for shares of Common Stock during the period from the date of the lock-up agreement continuing through the date 180 days after November 6, 2014, except with the prior written consent of J.P. Morgan Securities LLC and Credit Suisse Securities (USA) LLC.

The foregoing description of the lock-up agreement is qualified in its entirety by reference to the form of the lock-up agreement, which is filed as Exhibit B to this Schedule 13D and incorporated by reference herein.

Investor Rights Agreement

Under Third Amended and Restated Investor Rights Agreement, following the closing of the initial public offering of the Issuer, KKR Biosimilar has the right to require the Issuer to register its shares under the Securities Act of 1933, as amended, so that those shares may be publicly resold, or to include their shares in any registration statement the Issuer files, in each case as described below.

Demand Registration Rights

Based on the number of shares outstanding as of June 30, 2014, after the consummation of the Issuer’s initial public offering, the holders of approximately 21.3 million shares of the Issuer’s Common Stock (including KKR Biosimilar) or their transferees, will be entitled to certain demand registration rights. Beginning 180 days following November 6, 2014, the holders of at least 50% of these shares can, on not more than four occasions, request that the Issuer register all or a portion of their shares which they had received upon conversion of the convertible preferred stock held prior to the Issuer’s initial public offering. Such request for registration must cover a number of shares with an anticipated aggregate offering price, net of underwriting discounts and commissions, of at least $5.0 million. Additionally, the Issuer will not be required to effect a demand registration during the period beginning 60 days prior to the filing and 180 days following the effectiveness of an Issuer-initiated registration statement relating to a public offering of its securities, provided that the Issuer has complied with certain notice requirements to the holders of these shares.

Form S-3 Registration Rights

Such holders will also be entitled to certain Form S-3 registration rights whereby they can make a written request that the Issuer register shares which they had received upon conversion of the convertible preferred stock held prior to the Issuer’s initial public offering on Form S-3 if the Issuer is eligible to file a registration statement on Form S-3 and if the aggregate price to the public of the shares offered is at least $1.0 million. These stockholders may make an unlimited number of requests for registration on Form S-3, but in no event will the Issuer be required to file more than two registrations on Form S-3 in any 12-month period. However, the Issuer will not be required to effect a registration on Form S-3 during the period beginning 60 days prior to the filing and 180 days following the effectiveness of an Issuer-initiated registration statement relating to a public offering of its securities, provided that the Issuer has complied with certain notice requirements to the holders of these shares.

Piggyback Registration Rights

In the event that the Issuer determines to register any of its securities under the Securities Act of 1933, as amended, (subject to certain exceptions), either for its own account or for the account of other security holders, the holders of approximately 21.3 million shares of Common Stock (including KKR Biosimilar) or their transferees, will be entitled to certain “piggyback” registration rights allowing the holders to include their shares which they had received upon conversion of the convertible preferred stock held prior to the Issuer’s initial public offering in such registration, subject to certain marketing and other limitations. As a result, whenever the Issuer proposes to file a registration statement under the Securities Act of 1933, as amended, other than with respect to a registration related to employee benefit plans, the offer and sale of debt securities or corporate reorganizations or certain other transactions, the holders of these shares are entitled to notice of the registration and have the right, subject to limitations that the underwriters may impose on the number of shares included in the registration, to include such shares in the registration.

Expenses of Registration

The Issuer will pay the registration expenses of the holders of the shares registered pursuant to the demand, piggyback and Form S-3 registration rights described above.

14

Expiration of Registration Rights

The demand, piggyback and Form S-3 registration rights described above will expire, with respect to any particular stockholder, upon the earlier of five years after the consummation of the initial public offering or when that stockholder can sell all of its shares under Rule 144 of the Securities Act of 1933, as amended.

The foregoing description of the Third Amended and Restated Investor Rights Agreement is qualified in its entirety by reference to the Third Amended and Restated Investor Rights Agreement, which is filed as Exhibit C to this Schedule 13D and incorporated by reference herein.
