This Amendment No. 3 (this “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO filed by Mystic River Merger Sub Inc., a Delaware corporation (“Purchaser”), and Ultragenyx Pharmaceutical Inc., a Delaware corporation (“Parent”), with the U.S. Securities and Exchange Commission on October 10, 2017 (together with any subsequent amendments and supplements thereto, the “Schedule TO”). The Schedule TO relates to the offer by Purchaser to purchase all outstanding shares of common stock, $0.0001 par value per share (“Shares”), of Dimension Therapeutics, Inc., a Delaware corporation (“Dimension”), at a price of $6.00 per Share, net to the holder in cash, without interest upon the terms and subject to the conditions described in the Offer to Purchase dated October 10, 2017 (together with any amendments or supplements thereto, the “Offer to Purchase”) and in the accompanying Letter of Transmittal (together with any amendments or supplements thereto, the “Letter of Transmittal,” and with the Offer to Purchase, the “Offer”), which are annexed to and filed with this Schedule TO as Exhibits (a)(1)(A) and (a)(1)(B), respectively. Purchaser is a wholly-owned subsidiary of Parent. This Amendment is being filed on behalf of Parent and Purchaser. Unless otherwise indicated, references to sections in this Schedule TO are references to sections of the Offer to Purchase.

Amendments to the Offer to Purchase

Items 1 through 11.

The information set forth in the Offer to Purchase under “The Tender Offer—Section 15—Certain Legal Matters; Regulatory Approvals” and Items 1 through 11 of the Schedule TO, to the extent such Items incorporate by reference the information contained in the Offer to Purchase, are hereby amended and supplemented by replacing in its entirety the paragraph entitled “Legal Proceedings Related to the Tender Offer” which begins on page 51 of the Offer to Purchase with the following three paragraphs:

“Legal Proceedings Related to the Tender Offer

On October 11, 2017, a purported stockholder of Dimension filed a putative class action lawsuit against Dimension, its directors, Parent and Purchaser in the United States District Court for the District of Massachusetts, captioned Louis Scarantino v. Dimension Therapeutics, Inc. et al., Case No. 1:17-cv-11964 (the “Scarantino Complaint”). Among other things, the Scarantino Complaint alleges that Dimension, and its directors in their capacity as controlling persons, violated federal securities laws by failing to disclose material information in the Schedule 14D-9. In addition, the Scarantino Complaint alleges that Parent acted as a controlling person of Dimension within the meaning and in violation of Section 20(a) of the Exchange Act to influence and control the dissemination of the allegedly defective Schedule 14D-9. The Scarantino Complaint seeks, among other things, an order enjoining consummation of the Transactions, rescission of the Transactions if they have already been consummated or rescissory damages, an order directing the directors of Dimension to file a solicitation statement that does not contain any untrue statement of material fact and that states all material facts required in order to make the statements contained therein not misleading, a declaration that the defendants violated Sections 14(e), 14(d), 20(a) and Rule 14d-9 of the Exchange Act, and an award of plaintiffs’ costs, including reasonable allowance for attorneys’ fees and experts’ fees.

On October 15, 2017, another purported stockholder of Dimension filed a putative class action lawsuit against Dimension and its directors in the United States District Court for the District of Massachusetts, captioned Michael Rubin v. Dimension Therapeutics, Inc. et al., Case No. 1:17-cv-11992 (the “Rubin Complaint”). Among other things, the Rubin Complaint alleges that Dimension, and its directors in their capacity as controlling persons, violated federal securities laws by failing to disclose material information in the Schedule 14D-9. The Rubin Complaint seeks, among other things, an order enjoining consummation of the Transactions, rescission of the Transactions if they have already been consummated or rescissory damages, and an award of plaintiffs’ costs, including reasonable allowance for attorneys’ fees and experts’ fees. Neither Parent nor Purchaser are named as a defendant in the Rubin Complaint.

Dimension believes that both the Scarantino Complaint and the Rubin Complaint are without merit and that no further disclosure is required to supplement the Schedule 14D-9 under applicable laws.”
