Item 1.01   Entry into a Material Definitive Agreement.
On April 11, 2013, Sunshine Heart, Inc. (the
"Company"
) entered into an Underwriting Agreement (the
"Underwriting Agreement"
) with Canaccord Genuity Inc. (the
"Underwriter"
), pursuant to which the Company agreed to issue and sell 2,500,000 shares of its common stock, $0.0001 par value per share, at a public offering price of $5.25 per share (the
"Offering"
).   Under the terms of the Underwriting Agreement, the Company granted the Underwriter a 30-day option to purchase up to an additional 375,000 shares of the Company's common stock solely to cover over-allotments, if any.  The Company expects to receive approximately $12.2 million in net proceeds from the Offering (excluding the over-allotment option), after underwriting discounts and estimated expenses.  The offering is scheduled to close on or about April 16, 2013, subject to customary closing conditions.
The Underwriting Agreement contains representations, warranties and covenants made by the Company that are customary for transactions of this type.  Under the terms of the Underwriting Agreement, the Company has agreed to indemnify the Underwriter against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the
"Securities Act"
).  In addition, pursuant to the terms of the Underwriting Agreement, the Company and its executive officers and directors have entered into agreements with the Underwriter providing that the Company and each of these persons may not, without the prior written approval of the Underwriter, subject to limited exceptions, offer, sell, transfer or otherwise dispose of the Company's securities for a period of 90 days following the Offering.
The Offering was made pursuant to the Company's Registration Statement on Form S-3 (Registration No. 333-187273), filed with the Securities and Exchange Commission (the
"SEC"
) on March 15, 2013 and declared effective by the SEC on April 5, 2013, and the related prospectus supplement dated April 11, 2013.
A copy of the Underwriting Agreement is filed as Exhibit 1.1 and is incorporated herein by reference.  The foregoing description of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to such exhibit.
The opinion of the Company's counsel regarding the legality of the shares issued pursuant to the Offering is also filed as Exhibit 5.1.
Item 8.01   Other Events.
On April 11, 2013, the Company issued a press release announcing the terms of the Offering.  A copy of the press release dated April 11, 2013 is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
