This Amendment No. 1 ("Amendment No. 1") amends and supplements the statement on Schedule 13D filed with the Securities and Exchange Commission (the "SEC") on July 7, 2014 (the "Original Schedule 13D" and together with this Amendment No. 1, the "Schedule 13D") with respect to the shares ("Shares") of common stock, par value $0.001 per share, of Supernus Pharmaceuticals, Inc., a Delaware corporation (the "Issuer"). Capitalized terms used herein and not otherwise defined in this Amendment No. 1 have the meanings set forth in the Schedule 13D. This Amendment No. 1 amends Items 3, 4, 5 and 7 as set forth below.

Item 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

 

Item 3 of the Schedule 13D is hereby amended and restated as follows:

 

The 3,165,177 Shares (including the Convertible Notes) reported herein by the Reporting Person were acquired at an aggregate purchase price of approximately $22,838,544. Such Shares (and the Convertible Notes) were acquired with the working capital of the Fund and margin account borrowings made in the ordinary course of business. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the account, which may exist from time to time. Since other securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the Shares or Convertible Notes reported herein.

 

Item 4. PURPOSE OF TRANSACTION.

 

Item 4 of the Schedule 13D is hereby amended and supplemented by the addition of the following:

 

On September 9, 2014, the Reporting Person sent a letter to the Issuer’s Board of Directors. A copy of the letter is attached as Exhibit B to this Amendment No. 1 and is incorporated by reference herein.

 

Item 5. INTEREST IN SECURITIES OF THE COMPANY.

 

Items 5(a), (b) and (c) of the Schedule 13D are hereby amended and restated in their entirety as follows:

 

(a) See rows (11) and (13) of the cover page to this Schedule 13D for the aggregate number of Shares and the percentage of the Shares beneficially owned by the Reporting Person.  The percentage reported in this Amendment No. 1 is calculated based upon the 44,942,039 Shares reported to be outstanding as of July 31, 2014, as reported in the Issuer's Quarterly Report on Form 10-Q filed with the SEC on August 12, 2014, and assumes conversion of the Convertible Notes.
   
(b) See rows (7) through (10) of the cover page to this Amendment No. 1 for the number of Shares as to which each Reporting Person has the sole or shared power to vote or direct the vote and sole or shared power to dispose or to direct the disposition.
   
(c) Information concerning transactions in the Shares effected by the Reporting Person during the past sixty days is set forth in Exhibit A hereto and is incorporated herein by reference.
