This Amendment No. 1 (this “Amendment”), dated as of January 22, 2007, to the Rule 10b5-1 Sales Plan dated December 8, 2006 (the “Plan”) between RFE VI SBIC, L.P. (“Seller”) and Jefferies & Company, Inc. (“Broker”), acting as agent for Seller.

A.            The Plan was entered into between Seller and Broker for the purpose of establishing a trading plan with respect to the Common Stock of Sun Healthcare Group, Inc.

The parties hereto confirm and agree that, effective immediately, the term Pro Rata Limit in the Plan is hereby amended and restated to read in its entirety as follows:  “For all purposes of the Plan, the term “Pro Rata Limit” shall be defined as follows: “For purposes hereof, the “Pro Rata Limit” of Client shall be equal to a number of shares of Stock equal to (x) the number of Outstanding Shares multiplied by (y) Client’s Pro Rata Percentage.  For purposes hereof, “Client’s Pro Rata Percentage” shall be equal to 1.4763%.”

Except as amended hereby, the Plan shall remain in full force and effect in accordance with its terms.  This Amendment may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.  This Amendment shall be governed by and construed in accordance with the internal laws of the State of New York and may be modified or amended only by a writing signed by the parties hereto.

IN WITNESS WHEREOF, the undersigned have signed this Sales Plan as of the date first written above.
