Source and Amount of Funds or Other Consideration.

The Reporting Persons previously reported their ownership interest in the Issuer on Schedule 13G, as last amended on February 13, 2019.

CUSIP No. 185575107

13D

Page 13 of 21 Pages

On February 24, 2019, the Issuer and certain parties entered into an Arrangement Agreement (the "Arrangement Agreement") pursuant to which the Issuer has agreed to sell to Ipsen S.A. ("Ipsen") and 11188291 Canada Inc., ("Canada"), a wholly-owned subsidiary of Ipsen, all of the issued and outstanding Common Stock of the Issuer for $25.00 per share plus the contingent value right of $6.00 per Common Stock with certain conditions (the "Arrangement"). In connection with Ipsen and Canada's entry into the Arrangement Agreement, certain shareholders each entered into a Support and Voting Agreement (the "Support and Voting Agreements") with Ipsen and Canada on February 24, 2019 to vote the Common Stock that they own in favor of the approval of the Arrangement and in favor of any other matter necessary for the consummation of the transactions contemplated by the Arrangement Agreement. The Support and Voting Agreements will automatically terminate upon certain events, including the termination of the Arrangement Agreement. The foregoing descriptions of the Arrangement Agreement and the Support and Voting Agreements are qualified in their entirety by reference to the full text of such agreements. The Arrangement Agreement and the Support and Voting Agreements are filed as Exhibits 99.2 and 99.3 of the Issuer's Form 6-K filed with the Securities and Exchange Commission ("SEC") on February 25, 2019 and are incorporated herein by reference.

NEA 15 holds 2,706,283 shares of the Issuer's Common Stock (the "NEA 15 Shares"), obtained in a series of private transactions. On March 4, 2019, NEA 15 entered into a Support and Voting Agreement (the "Agreement") with Ipsen and Canada whereby NEA 15 agrees to vote the NEA 15 Shares in favor of the Arrangement and in favor of any other matter necessary for the consummation of the transactions contemplated by the Arrangement Agreement.

The working capital of NEA 15 was the source of the funds for the purchase of the NEA 15 Shares. No part of the purchase price of the NEA 15 Shares was represented by funds or other consideration borrowed or otherwise obtained for the purpose of acquiring, holding, trading or voting the NEA 15 Shares.

Item 4.

Purpose of Transaction.

NEA 15 acquired the NEA 15 Shares for investment purposes. Depending on market conditions, its continuing evaluation of the business and prospects of the Issuer and other factors, NEA 15 and other Reporting Persons may dispose of or acquire additional shares of the Issuer.
