     This Separation and General Release Agreement (the "Agreement") is entered into between PAUL R. HAMELIN, with an address at 2998 South Lake Leelanau Road, Lake Leelanau, Michigan 49653 ("Executive") and SAVIENT PHARMACEUTICALS, INC., a Delaware corporation with an address at One Tower Center, 14th Floor, East Brunswick, New Jersey 08816 (the “Company”). The Company, together with its past, present and future parent entities, subsidiaries, affiliated entities, related companies and divisions and each of the respective past, present and future officers, directors, employees, shareholders, members, partners, trustees, employee benefit plans (and such plans' fiduciaries, agents, administrators and insurers), attorneys, and agents (individually and in their official capacities), as well as any predecessors, future successors or assigns or estates of any of the foregoing, is collectively referred to in this Agreement as the "Released Parties."

     A. The Company and Executive entered into an employment agreement, effective as of May 23, 2006 (the "Original Employment Agreement"). The Original Employment Agreement was amended by separate amendments to employment agreement by and between the Company and Executive, effective as of February 15, 2008 and December 19, 2008 (the "Employment Agreement Amendment", or individually the “First Employment Agreement Amendment” and “Second Employment Agreement Amendment”, respectively). The Original Employment Agreement, as amended by the Employment Agreement Amendment, shall be referred to in this Agreement as the "Employment Agreement." Capitalized terms used in this Agreement and not otherwise defined in this Agreement shall have the meanings ascribed to them in the Employment Agreement. This Agreement is first presented to Executive on April 1, 2011.

     B. The Board of Directors of the Company (the "Board") and Executive have mutually agreed and determined that Executive shall separate from his position as the Company's President and from his employment with the Company, effective May 30, 2011.

     C. Notwithstanding the mutual agreement between the Company and Executive regarding his separation from his employment with the Company, the Company has agreed to treat the Executive's separation from employment, for purposes of advance notice of termination and Severance Benefits, as an involuntary termination by the Company without Cause pursuant to Section 7.4 of the Employment Agreement; provided, however, as a condition to Executive's receipt of the payments and benefits set forth in Sections 7.4(b)(1)-(3) of the Employment Agreement and Section 2 hereof, Executive is required to (i) execute, deliver (within the time frames provided), and not revoke this Agreement, and (ii) complete, to the satisfaction of the Company, the transition of Executive’s duties and responsibilities and assistance as specified in Section 1(B).

     D. Accordingly, pursuant to a Notice of Termination dated April 1, 2011 (the "Notice Date"), the Company invoked Section 7.4 of the Employment Agreement and terminated Executive's employment with the Company without Cause, effective May 30, 2011.

     E. The Executive has requested, after conferring with his legal counsel, that the severance payments described herein not be subject to the "six month delay" applicable to "specified employees" as described in Section 409A of the Internal Revenue Code of 1986, as amended (the "Code"), and accordingly that such severance payments to be paid to the Executive hereunder should commence as described herein and without the imposition of an "additional tax" under such Section 409A.

     F. Each of the parties hereto believes it to be in their respective best interests to enter into an agreement to set forth the terms of their respective rights and obligations relating to the Executive's separation from the Company.
