On July 1, 2013, a Certificate of Conversion was filed with the State of Delaware to convert Baker Bros. Advisors, LLC from a limited liability company into a limited partnership named Baker Bros. Advisors LP (the “Adviser”). Baker Bros. Advisors (GP) LLC (the “Adviser GP”) is the sole general partner of the Adviser.

 

Pursuant to the amended and restated management agreements, as amended, among the Adviser, Baker Brothers Life Sciences, L.P. (“Life Sciences”), 14159, L.P. (“14159”), and 667, L.P. (“667”, and together with Life Sciences and 14159, the “Funds”), and their respective general partners, the Adviser has complete and unlimited discretion and authority with respect to the Funds’ investments and voting power over investments.

(a) The Reporting Persons are:

1.The Adviser
2.The Adviser GP
3.Felix J. Baker
4.Julian C. Baker

 

(b) The business address of each of the Reporting Persons is:

(c) The Adviser is an entity engaged in investment activities, and the Adviser GP is in the business of acting as its general partner and, through the Adviser, investment activities. The principal business of each of Julian C. Baker and Felix J. Baker is to serve as a managing member of the Adviser GP.

 

(d) and (e) During the past five years, none of the Reporting Persons nor any of the Funds has been (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

 

(f) The Adviser GP is a limited liability company organized under the laws of the State of Delaware. The Adviser is a limited partnership organized under the laws of the State of Delaware. The citizenship of each of Julian C. Baker and Felix J. Baker is the United States of America.

 

 
 

 

Item 5.Interest in Securities of the Issuer.

 

(a) and (b) Items 7 through 11 and 13 of each of the cover pages of this Amendment No. 5 are incorporated herein by reference.

 

The Adviser GP, Felix J. Baker and Julian C. Baker as principals of the Adviser GP, and the Adviser may be deemed to be beneficial owners of securities of the Issuer directly held by the Funds, and may be deemed to have the power to vote or direct the vote of and the power to dispose or direct the disposition of such securities.

 

The Reporting Persons disclaim beneficial ownership of the securities held by each of the Funds, and this Amendment No. 5 shall not be deemed an admission that the Reporting Persons are the beneficial owners of such securities for purposes of Section 13(d) or for any other purpose.

 

(c) On May 23, 2013 Dr. Kelvin Neu, a Managing Director of the Adviser, in connection with his service on the Board of Directors of the Issuer (the “Board”), was granted 8,400 Restricted Stock Units (“Restricted Stock Units”) payable solely in Common Shares which vest in substantially equal installment over three years beginning on May 29, 2014. Additionally on May 23, 2013 Dr. Neu, in connection with his service on the Board, was granted 11,600 options to purchase common stock of the Issuer (“Stock Options”) at $4.13 per share vesting in 12 equal monthly installment beginning on the date of grant and expiring 10 years from the date of grant. Dr. Neu may from time to time in the future receive additional securities of the Issuer as compensation for his service on the Issuer’s board of directors, consistent with other non-employee directors of the Issuer.

 

Dr. Neu serves on the Issuer’s Board as a representative of the Funds. Pursuant to the policies of the Adviser, Dr. Neu does not have any right to receive any profits from any securities as compensation for serving as Director of the Issuer and therefore has no pecuniary interest in the Restricted Stock Units or Stock Options. The Funds are entitled to the pecuniary interest in the Restricted Stock Units and Stock Options as each holds an indirect pecuniary interest. Dr. Neu currently retains voting and investment power over the shares of Restricted Stock Units and Stock Options.

 

Except as otherwise disclosed in this or any previously filed Schedule 13D, none of the Reporting Persons or their affiliates has effected any transaction in the securities of the Issuer in the past sixty days.
