Ladies and Gentlemen:

Sunshine Heart, Inc., a Delaware corporation (the “Company”), proposes to sell to the several Underwriters named in Schedule I hereto (the “Underwriters”) an aggregate of 2,500,000 shares (the “Firm Shares”) of Common Stock, $0.0001 par value per share (the “Common Stock”), of the Company. The Company has also granted to the several Underwriters an option to purchase up to 375,000 additional shares of Common Stock on the terms and for the purposes set forth in Section 3 hereof (the “Option Shares”). The Firm Shares and any Option Shares purchased pursuant to this Underwriting Agreement are herein collectively called the “Securities.”

The Company hereby confirms its agreement with respect to the sale of the Securities to the several Underwriters, for whom you are acting as representative (the “Representative”).

1. Registration Statement and Prospectus.

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a shelf registration statement on Form S-3 (File No. 333-187273) under the Securities Act of 1933, as amended (the “Act”), and the rules and regulations (the “Rules and Regulations”) of the Commission thereunder, including the base prospectus relating to the registration of certain securities described therein, and such amendments to such registration statement (including any post-effective amendments) as may have been required to the date of this Agreement. Such registration statement, at any given time, including the amendments thereto (including any post-effective amendments) to the date of this Agreement, the exhibits and any schedules thereto to the date of this Agreement and the documents and information otherwise deemed to be a part thereof or included therein by Rule 430B of the Rules and Regulations or otherwise pursuant to the Rules and Regulations to the date of this Agreement, is herein referred to as the “Registration Statement.” The base prospectus contained in the Registration Statement, as of the date it was declared effective, or in the form it was most recently filed with the Commission on or prior to the date of this Agreement, is referred to as the “Base Prospectus.” If the Company has filed or files an abbreviated registration statement to register additional securities pursuant to Rule 462(b) of the Rules and Regulations (the “462(b) Registration Statement”), then any reference herein to the term Registration Statement shall also be deemed to include such 462(b) Registration Statement.

The Company will prepare and file a final prospectus supplement to the Base Prospectus relating to the Securities with the Commission pursuant to Rules 424(b) and 430B of the Rules and Regulations in the form heretofore delivered to the Underwriters. The Base Prospectus, as supplemented by such final prospectus supplement, in the form

(1) Plus an option to purchase up to 375,000 additional shares to cover over-allotments.

in which it is first filed with the Commission pursuant to Rule 424(b) under the Act, is referred to herein as the “Final Prospectus.” The Final Prospectus, or any preliminary prospectus supplement or prospectus filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations, including the Base Prospectus, is hereafter called a “Prospectus.”

For purposes of this Agreement, all references to the Registration Statement or any Prospectus shall be deemed to refer to and include the documents incorporated by reference therein or otherwise deemed by the Rules and Regulations to be a part thereof. For purposes of this Agreement, all references to amendments or supplements to the Registration Statement, the Time of Sale Information or any Prospectus shall be deemed to refer to and to include the filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that is or is deemed to be incorporated by reference therein or otherwise deemed by the Rules and Regulations to be a part thereof. For purposes of this Agreement, all references to the Registration Statement or any Prospectus, or any amendment or supplement thereto, shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“XXXXX”). All references in this Agreement to financial statements and schedules and other information that is “described,” “contained,” “included” or “stated” in the Registration Statement or any Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements, pro forma financial information and schedules and other information that is incorporated by reference in or otherwise deemed by the Rules and Regulations to be a part of or included in the Registration Statement or any Prospectus, as the case may be.

(viii) Except as contemplated in the Time of Sale Disclosure Package and in the Final Prospectus, subsequent to the respective dates as of which information is given in the Time of Sale Disclosure Package, neither the Company nor its Subsidiary has incurred any material liabilities or obligations, other than those incurred in the ordinary course of business, direct or contingent, or entered into any material transactions, or declared or paid any dividends or made any distribution of any kind with respect to its capital stock; and there has not been any change in the capital stock (other than a change in the number of outstanding shares of Common Stock due to the issuance of shares upon the exercise of outstanding options or warrants), or any material change in the short-term or long-term debt, or any issuance of options, warrants, convertible securities or other rights to purchase the capital stock other than pursuant to the Company’s Amended and Restated 2002 Stock Plan or 2011 Equity Incentive Plan, of the Company or its Subsidiary, or any material adverse change in the business, prospects (to the extent disclosed in the Final Prospectus), management, properties, operations, condition (financial or otherwise), or results of operations of the Company and its Subsidiary, taken as a whole (“Material Adverse Change”) or any development which would reasonably be expected to result in any Material Adverse Change.

time to time, except as described in or contemplated by the Registration Statement (excluding the exhibits thereto), the Time of Sale Disclosure Package and the Final Prospectus.

(xxxviii) The Company has no reason to believe that any third-party statistical and market-related data included in the Registration Statement, the Time of Sale Disclosure Package and the Final Prospectus are not based on or derived from sources that are reliable and accurate in all material respects.

(xl) Neither the Company nor its Subsidiary is, and after giving effect to the offering and sale of the Securities neither the Company nor its Subsidiary will be, a “holding company” or a “subsidiary company” of a “holding company” or an “affiliate” of a “holding company” or of a “subsidiary company,” as such terms are defined in the Public Utility Holding Company Act of 1935, as amended.

(xliv) Neither the Company nor its Subsidiary nor any of their respective directors, officers or, to the knowledge of the Company, any of their affiliates or controlling persons has taken, directly or indirectly, any action designed, or which has constituted or might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(xlv) From the time of filing of the Registration Statement with the Commission (or, if earlier, the first date on which the Company engaged directly or through any person authorized to act on its behalf in any oral or written communication with potential investors undertaken in reliance on Section 5(d) of the Act (any “Testing-the-Waters Communication”)) through the date hereof, the

(b) Any certificate signed by any officer of the Company and delivered to you or to counsel for the Underwriters shall be deemed a representation and warranty by the Company to each Underwriter as to the matters covered thereby.

3. Purchase, Sale and Delivery of Securities.

(a) On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to issue and sell 2,500,000 Firm Shares to the several Underwriters, and each Underwriter agrees, severally and not jointly, to purchase from the Company the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I hereto. The purchase price for each Firm Share shall be $4.9534 per share. In making this Agreement, each Underwriter is contracting severally and not jointly; except as provided in paragraph (c) of this Section 3 and in Section 8 hereof, the agreement of each Underwriter is to purchase only the respective number of Firm Shares specified in Schedule I.

The Firm Shares will be delivered by the Company to you for the accounts of the several Underwriters against payment of the purchase price therefor by wire transfer of same day funds payable to the order of the Company at the offices of Canaccord Genuity Inc., 99 Xxxx Xxxxxx, 00xx Xxxxx, Xxxxxx, Xxxxxxxxxxxxx, or such other location as may be mutually acceptable, at 9:00 a.m., Eastern time, on the third (or if the Securities are priced, as contemplated by Rule 15c6-1(c) under the Exchange Act, after 4:30 p.m., Eastern time, the fourth) full business day following the date hereof, or at such other time and date as you and the Company determine pursuant to Rule 15c6-1(a) under the Exchange Act, such time and date of delivery being herein referred to as the “First Closing Date.” The Firm Shares will be credited through full fast transfer to the accounts at The Depository Trust Company as designated by the Representative.

(b) On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company hereby grants to the several Underwriters an option to purchase all or any portion of the Option Shares at the same purchase price as the Firm Shares, for use solely in covering any over-allotments made by the Underwriters in the sale and distribution of the Firm Shares. The option granted hereunder may be exercised in whole or in part at any time (but not more than once) within 30 days after the effective date of this Agreement upon notice (confirmed in writing) by the Representative to the Company setting forth the aggregate number of Option Shares as to which the several Underwriters are exercising the option, the names and denominations in which the Option Shares are to be registered and the date and time, as determined by you, when the Option Shares are to be delivered, such time and date being herein referred to as the “Second Closing” and “Second Closing Date” (each of the First Closing Date and the Second Closing Date, a “Closing Date”), respectively; provided, however, that the Second Closing Date shall not be earlier than the First Closing Date nor earlier than the second business day after the date on which the option shall have been exercised, unless the Representative has exercised the option to purchase all or a portion of the Option Shares within one business day after the date of this Agreement, in which case the Company may,

at its option, close the Second Closing on the First Closing Date. The number of Option Shares to be purchased by each Underwriter shall be the same percentage of the total number of Option Shares to be purchased by the several Underwriters as the number of Firm Shares to be purchased by such Underwriter is of the total number of Firm Shares to be purchased by the several Underwriters, as adjusted by the Representative in such manner as the Representative deems advisable to avoid fractional shares. No Option Shares shall be sold and delivered unless the Firm Shares previously have been, or simultaneously are, sold and delivered.

The Option Shares will be delivered by the Company to you for the accounts of the several Underwriters against payment of the purchase price therefor by wire transfer of same day funds payable to the order of the Company at the offices of Canaccord Genuity Inc., 99 Xxxx Xxxxxx, 00xx Xxxxx, Xxxxxx, Xxxxxxxxxxxxx, or such other location as may be mutually acceptable at 9:00 a.m., Eastern time, on the Second Closing Date. The delivery of the Option Shares will be credited through full fast transfer to the accounts at The Depository Trust Company as designated by the Representative.

(c) It is understood that you, individually and not as Representative of the several Underwriters, may (but shall not be obligated to) make payment to the Company on behalf of any Underwriter for the Securities to be purchased by such Underwriter. Any such payment by you shall not relieve any such Underwriter of any of its obligations hereunder. Nothing herein contained shall constitute any of the Underwriters an unincorporated association or partner with the Company.

4. Covenants. The Company covenants and agrees with the several Underwriters as follows:

(a) If the Company has elected to rely upon Rule 462(b) of the Rules and Regulations to increase the size of the offering registered under the Act and the Rule 462(b) Registration Statement has not yet been filed and become effective, the Company will prepare and file the Rule 462(b) Registration Statement with the Commission within the time period required by, and otherwise in accordance with the provisions of, Rule 462(b) and the Act; prior to the First Closing, the Company will prepare and file with the Commission, promptly upon your reasonable request, any amendments or supplements to the Registration Statement or Prospectus that, based on the advice of counsel, are necessary or advisable in connection with the distribution of the Securities by the Underwriters; and the Company will furnish the Representative and counsel for the Underwriters a copy of any proposed amendment or supplement to the Registration Statement or Prospectus and will not file any amendment or supplement to the Registration Statement or Prospectus to which you shall reasonably object by notice to the Company after having been furnished a copy a reasonable time prior to the filing.

(b) The Company will advise you, promptly after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, or any post-effective amendment thereto or preventing or suspending the use of the Time of Sale Disclosure Package, any Prospectus or any Issuer Free Writing Prospectus, of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceeding for any such purpose; and after receipt of notice, the Company will use its reasonable best efforts to prevent the issuance of any stop order or to obtain its lifting if such a stop order should be issued. Additionally, the Company agrees that it shall comply with the provisions of Rules 424(b), 430A and 430B, as applicable, under the Act and will use its reasonable efforts to confirm that any filings made by the Company under Rule 424(b), Rule 433 or Rule 462 were received in a timely manner by the Commission.

(c) (i) Within the time during which a prospectus (assuming the absence of Rule 172) relating to the Securities is required to be delivered under the Act by any Underwriter or dealer in connection with sales by an Underwriter or dealer (the “Prospectus Delivery Period”), the Company will use reasonable best efforts to comply with all requirements imposed upon it by the Act, as now and hereafter amended, and by the Rules and Regulations, as from time to time in force, so far as necessary to permit the continuance of sales of or dealings in the Securities as contemplated by the provisions hereof, the Time of Sale Disclosure Package and the Final Prospectus. If during such period any event occurs as a result of which the Final Prospectus (or if the Final Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances then existing, not misleading, or if during such period it is necessary to amend the Registration Statement or supplement the Final Prospectus (or if the Final Prospectus is not yet available to prospective investors, the Time of Sale Disclosure Package) to comply with the Act, the Company will

promptly notify you and will amend the Registration Statement or supplement the Final Prospectus (or, if the Final Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) (at the expense of the Company) so as to correct such statement or omission or effect such compliance.

(ii) If at any time following issuance of an Issuer Free Writing Prospectus there occurred, or through the Prospectus Delivery Period occurs, an event or development as a result of which such Issuer Free Writing Prospectus conflicted or during such time would conflict with the information contained in the Registration Statement or any Prospectus relating to the Securities or included or during such time would include an untrue statement of a material fact or omitted or during such time would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company has promptly notified or promptly will notify the Representative and has promptly amended or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(d) The Company shall take or cause to be taken all necessary action to qualify the Securities for sale under the securities laws of such jurisdictions as you reasonably designate or and to continue such qualifications in effect so long as required for the distribution of the Securities, except that the Company shall not be required in connection therewith to qualify as a foreign corporation or to execute a general consent to service of process in any state.

(e) The Company will furnish, at its own expense, to the Underwriters and counsel for the Underwriters copies of the Registration Statement (three of which will be signed and will include all consents and exhibits filed therewith), and to the Underwriters and any dealer each Prospectus, the Time of Sale Disclosure Package, any Issuer Free Writing Prospectus and all amendments and supplements to such documents, in each case as soon as available and in such quantities as you may from time to time reasonably request.

(f) The Company will make generally available to its security holders as soon as practicable, but in no event later than 15 months after the end of the Company’s current fiscal quarter, an earnings statement (which need not be audited) covering a 12-month period that shall satisfy the provisions of Section 11(a) of the Act and Rule 158 of the Rules and Regulations. The parties agree that such obligation may be satisfied by filings with the Commission made on XXXXX.

(g) The Company, whether or not the transactions contemplated hereunder are consummated or this Agreement is terminated, will pay or cause to be paid (i) all expenses (including transfer taxes allocated to the respective transferees of the Securities) incurred in connection with the delivery to the Underwriters of the Securities, (ii) all expenses and fees (including, without limitation, fees and expenses of the Company’s accountants and legal counsel) in connection with the preparation, printing, filing, delivery, and shipping of the Registration Statement (including the financial statements therein and all amendments, schedules, and exhibits thereto), the Securities, each Preliminary Prospectus, the Time of Sale Disclosure Package, the Final Prospectus, any Issuer Free Writing Prospectus and any amendment thereof or supplement thereto, and the printing, delivery, and shipping of this Agreement and other underwriting documents, including Blue Sky Memoranda (covering the states and other applicable jurisdictions), (iii) all filing fees and fees and disbursements of the Underwriters’ counsel incurred in connection with the qualification of the Securities for offering and sale by the Underwriters or by dealers under the securities or blue sky laws of the states and other jurisdictions which you shall designate, (iv) the fees and expenses of any transfer agent or registrar, (v) the filing fees and fees and disbursements of Underwriters’ counsel incident to any required review and approval by FINRA of the terms of the sale of the Securities, (vi) listing fees, if any, (vii) the cost and expenses of the Company relating to investor presentations or any “roadshow” undertaken in connection with marketing of the Securities, (viii) all other costs and expenses of the Underwriter incident to the performance of its obligations hereunder not otherwise specifically provided for herein, including the fees and expenses of the Underwriter’s legal counsel, provided, however that such costs and expenses provided for in this subsection (viii) (which, for the avoidance of doubt, shall include all fees and disbursements of Underwriters’ counsel other than those incurred in connection with the FINRA filing referred to in subsection (v), which fees and disbursements shall be reimbursed in full notwithstanding the cap set forth in this subsection (viii)) shall not exceed $80,000, and (ix) all other costs and expenses of the Company incident to the performance of its obligations hereunder that are not otherwise specifically provided for herein. If this Agreement is terminated by the Representative pursuant to Section 9 hereof or if the sale of the Securities provided for herein is not consummated by reason of any failure, refusal or inability on the part of the Company to perform any agreement on its or their part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be

fulfilled by the Company is not fulfilled, the Company will reimburse the several Underwriters for all reasonable out-of-pocket accountable disbursements (including but not limited to fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges) incurred by the Underwriters in connection with their investigation, preparing to market and marketing the Securities or in contemplation of performing their obligations hereunder. The Company shall not in any event be liable to any of the Underwriters for loss of anticipated profits from the transactions covered by this Agreement.

(h) The Company will apply the net proceeds from the sale of the Securities to be sold by it hereunder for the purposes set forth in the Time of Sale Disclosure Package and in the Final Prospectus and will file such reports with the Commission with respect to the sale of the Securities and the application of the proceeds therefrom as may be required in accordance with Rule 463 of the Rules and Regulations.

(i) The Company will not, without the prior written consent of Canaccord Genuity Inc., from the date of execution of this Agreement and continuing to and including the date 90 days after the date of the Final Prospectus (the “Lock-Up Period”), (i) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (including, for the avoidance of doubt, any sales of shares of Common Stock pursuant to the Common Stock Purchase Agreement, dated as of January 15, 2013, by and between the Company and Aspire Capital Fund, LLC) or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, except (A) to the Underwriters pursuant to this Agreement or (B) in the ordinary course of business pursuant to the Company’s Amended and Restated 2002 Stock Plan or 2011 Equity Incentive Plan. Except as required under any agreement existing on the date of this Agreement, the Company agrees not to accelerate the vesting of any option or warrant or the lapse of any repurchase right prior to the expiration of the Lock-Up Period. Notwithstanding the foregoing, the Company shall be permitted during the Lock-Up Period to file a post-effective amendment to its registration statement on Form S-1 (File No. 333-186259) for the purpose of reflecting in the prospectus contained in such registration statement facts or events representing a fundamental change in the information set forth in such registration statement as required by the undertaking set forth in Item 17(a)(1)(ii) of Part II of such registration statement.

(j) The Company has caused to be delivered to you prior to the date of this Agreement the Lock-Up Agreements from each of the Company’s directors and officers. If any additional persons shall become directors or officers of the Company prior to the end of the Lock-Up Period, the Company shall cause each such person, prior to or contemporaneously with their appointment or election as a director or officer of the Company, to execute and deliver to you a Lock-Up Agreement. The Company will issue stop-transfer instructions to the transfer agent for the Common Stock with respect to any transaction or contemplated transaction that would constitute a breach of or default under the Lock-Up Agreements.

(k) The Company agrees to announce the Underwriters’ intention to release any director or officer of the Company from any of the restrictions imposed by any Lock-Up Agreement, by issuing, through a major news service, a press release in form and substance satisfactory to you promptly following the Company’s receipt of any notification from you in which such intention is indicated, but in any case not later than the close of the third business day prior to the date on which such release or waiver is to become effective; provided, however, that nothing shall prevent you, on behalf of the Underwriters, from announcing the same through a major news service, irrespective of whether the Company has made the required announcement; provided further, that no such announcement shall be made of any release or waiver granted solely to permit a transfer of securities that is not for consideration and where the transferee has agreed in writing to be bound by the terms of a Lock-Up Agreement, in the form set forth as Exhibit A hereto.

(l) The Company has not taken and will not take any action designed to or which might reasonably be expected to cause or result in, or which has constituted, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(m) During the Prospectus Delivery Period, the Company will file on a timely basis with the Commission such periodic and special reports as required by the Rules and Regulations.

(n) During the Prospectus Delivery Period, the Company and its Subsidiary will comply with all applicable provisions of the Xxxxxxxx-Xxxxx Act.

(o) The Company represents and agrees that, unless it obtains the prior written consent of Canaccord Genuity Inc., and each Underwriter severally represents and agrees that, unless it obtains the prior written consent of the Company and Canaccord Genuity Inc., neither it nor its Subsidiary has made and will not make any offer relating to the Securities that would constitute an “issuer free writing prospectus,” as defined in Rule 433 under the Act, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405 under the Act, required to be filed with the Commission; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the free writing prospectuses included in Schedule II. Any such free writing prospectus consented to by the Company and Canaccord Genuity Inc. is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 164 and Rule 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping. The Company represents that it has satisfied and agrees that it will satisfy the conditions in Rule 433 to avoid a requirement to file with the Commission any electronic roadshow.

(p) The Company will promptly notify the Representative if the Company ceases to be an Emerging Growth Company at any time prior to the later of (i) completion of the distribution of the Securities within the meaning of the Act and (ii) completion of the Lock-Up Period referred to in Section 4(i) hereof. Furthermore, if at any time following the distribution of any Written Testing-the-Waters Communication with respect to Emerging Growth Company status of the Company there occurred or occurs an event or development as a result of which such Written Testing-the-Waters Communication included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at that subsequent time, not misleading, the Company will promptly notify the Representative and will promptly amend or supplement, at its own expense, such Written Testing-the-Waters Communication to eliminate or correct such untrue statement or omission.

5. Conditions of Underwriters’ Obligations. The obligations of the several Underwriters hereunder are subject to the accuracy, as of the date hereof and at each of the First Closing Date and the Second Closing Date (as if made at such Closing Date), of and compliance with all representations, warranties and agreements of the Company and its Subsidiary contained herein, to the performance by the Company of its obligations hereunder and to the following additional conditions:

(a) No stop order suspending the effectiveness of the Registration Statement or any part thereof or any amendment thereof, nor suspending or preventing the use of the Time of Sale Disclosure Package, the Final Prospectus or any Issuer Free Writing Prospectus shall have been issued; no proceedings for the issuance of such an order shall have been initiated or, to the Company’s knowledge, threatened; and any request of the Commission for additional information (to be included or incorporated by reference in the Registration Statement, the Time of Sale Disclosure Package, the Final Prospectus, any Issuer Free Writing Prospectus or otherwise) shall have been complied with to your satisfaction.

(b) If the Company has elected to rely upon Rule 430B of the Rules and Regulations, the information concerning the public offering price of the Securities and price-related information, and such other information omitted from any Prospectus in reliance on Rule 430B of the Rules and Regulations, shall have been filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations in the manner and within the prescribed time period (without reliance on Rule 424(b)(8) of the Rules and Regulations), and the Company will provide evidence satisfactory to the Representative of such timely filing (or a post-effective amendment providing such information shall have been filed and declared effective in accordance with the requirements of Rules 430B and 424(b) of the Rules and Regulations).

(c) If a Rule 462(b) Registration Statement is required, such Registration Statement shall have been transmitted to the Commission for filing and become effective within the prescribed time period and, prior to the First

Closing Date, the Company shall have provided evidence of such filing and effectiveness in accordance with Rule 462(b) of the Rules and Regulations.

(d) No Underwriter shall have advised the Company that (i) the Registration Statement or any amendment thereof or supplement thereto contains an untrue statement of a material fact which, in your opinion, is material or omits to state a material fact which, in your opinion based on the advice of your counsel, is required to be stated therein or necessary to make the statements therein not misleading, or (ii) the Time of Sale Disclosure Package or the Final Prospectus, or any amendment thereof or supplement thereto, or any Issuer Free Writing Prospectus contains an untrue statement of fact which, in your reasonable opinion based on the advice of counsel, is material, or omits to state a fact which, based on the advice of your counsel, is material and is required to be stated therein, or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading.

(e) Except as contemplated in the Time of Sale Disclosure Package and in the Final Prospectus, subsequent to the respective dates as of which information is given in the Time of Sale Disclosure Package, neither the Company nor its Subsidiary shall have incurred any material liabilities or obligations, other than those incurred in the ordinary course of business, direct or contingent, or entered into any material transactions, or declared or paid any dividends or made any distribution of any kind with respect to its capital stock; and there shall not have been any change in the capital stock (other than a change in the number of shares of Common Stock outstanding due to the issuance of shares upon the exercise of outstanding options or warrants), or any material change in the short-term or long-term debt of the Company or its Subsidiary, or any issuance of options, warrants, convertible securities or other rights to purchase the capital stock of the Company or its Subsidiary, or any Material Adverse Change or any development which would reasonably be expected to result in a Material Adverse Change (whether or not arising in the ordinary course of business), the effect of which, in any such case described above, in your judgment, makes it impractical or inadvisable to offer or deliver the Securities on the terms and in the manner contemplated in the Time of Sale Disclosure Package and in the Final Prospectus.

(f) On each Closing Date, there shall have been furnished to you, as Representative of the several Underwriters, (i) the opinion of Xxxxxxxx Xxxxxx Xxxxxxxx and Xxxx LLP, dated such Closing Date and addressed to you, in form and substance satisfactory to the Underwriters, (ii) the opinion of Xxxxxxx Winter & Xxxxxxxx, dated such Closing Date and addressed to you, in form and substance satisfactory to the Underwriters, and (iii) the opinion of Xxxxx, Brown, Koehn, Shors & Xxxxxxx, P.C., dated such Closing Date and addressed to you, in form and substance satisfactory to the Underwriters.

(h) On each Closing Date you, as Representative of the several Underwriters, shall have received a letter of Ernst & Young LLP, dated such date and addressed to you, confirming that it is an independent public accounting firm within the meaning of the Act and is in compliance with the applicable requirements relating to the qualifications of accountants under Rule 2-01 of Regulation S-X of the Commission, and stating, as of the date of such letter (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Time of Sale Disclosure Package, as of a date not prior to the date hereof or more than five days prior to the date of such letter), the conclusions and findings of said firm with respect to the financial information and other matters covered by its letter delivered to you concurrently with the execution of this Agreement, and the effect of the letter so to be delivered on such Closing Date shall be to confirm the conclusions and findings set forth in such prior letter.

(i) On each Closing Date, there shall have been furnished to you, as Representative of the several Underwriters, a certificate, dated such Closing Date and addressed to you, signed by the chief executive officer and by the chief financial officer of the Company, to the effect that:

(i) The representations and warranties of the Company in this Agreement are true and correct as if made at and as of such Closing Date, and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied under this Agreement at or prior to such Closing Date; and

(ii) No stop order or other order suspending the effectiveness of the Registration Statement or any part thereof or any amendment thereof or the qualification of the Securities for offering or sale, nor suspending or preventing the use of the Time of Sale Disclosure Package, the Final Prospectus or any Issuer Free Writing Prospectus, has been issued, and, to their knowledge, no proceeding for that purpose has been instituted or is contemplated by the Commission or any state or regulatory body.

The Company will furnish you with such conformed copies of such opinions, certificates, letters and other documents as you shall reasonably request.

6. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter from and against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise (including in settlement of any litigation if such settlement is effected with the written consent of the Company), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including the information deemed to be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to Rules 430A and 430B of the Rules and Regulations, the Time of Sale Disclosure Package or any Prospectus, or any amendment or supplement thereto (including any documents filed under the Exchange Act and deemed to be incorporated by reference into the Registration Statement or such Prospectus), any written Testing-the-Waters Communication, or any Issuer Free Writing Prospectus, or in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Common Stock (“Marketing Materials”), including any roadshow or investor presentations made to investors by the Company (whether in person or electronically), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of the Time of Sale Disclosure Package or any Prospectus, any Testing-the-Waters Communication or any Issuer Free Writing Prospectus, in light of the circumstances under which they were made) not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by it in connection with investigating or defending against such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Time of Sale Disclosure Package or any Prospectus, or any amendment or supplement thereto, any written Testing-the-Waters Communication, any Issuer Free Writing Prospectus or in any Marketing Materials, in reliance upon and in conformity with written information furnished to the Company by you, or by any Underwriter through you, specifically for use in the preparation thereof; it being understood and agreed that the only information furnished by an Underwriter consists of the information described as such in Section 6(f).

(b) Each Underwriter will, severally and not jointly, indemnify and hold harmless the Company from and against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Time of Sale Disclosure Package or any Prospectus, or any amendment or supplement thereto, any written Testing-the-Waters Communication, or any Issuer Free Writing Prospectus or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Time of Sale Disclosure Package or any Prospectus, or any amendment or supplement thereto, any written Testing-the-Waters Communication, or any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by you, or by such Underwriter through you, specifically for use in the preparation thereof (it being understood and agreed that the only information furnished by an Underwriter consists of the information described as such in Section 6(f)), and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending against any such loss, claim, damage, liability or action as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party except to the extent such indemnifying party has been materially prejudiced by such failure (through the forfeiture of substantive rights or defenses). In case any such action shall be brought against any indemnified party, and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of the indemnifying party’s election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that if, in the sole judgment of the Representative, it is advisable for the Underwriters to be represented as a group by separate counsel, the Representative shall have the right to employ a single counsel (in addition to local counsel) to represent the Representative and all Underwriters who may be subject to liability arising from any claim in respect of which indemnity may be sought by the Underwriters under subsection (a) of this Section 6, in which event the reasonable fees and expenses of such separate counsel shall be borne by the indemnifying party or parties and reimbursed to the Underwriters as incurred. An indemnifying party shall not be obligated under any settlement agreement relating to any action under this Section 6 to which it has not agreed in writing. In addition, no indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld or delayed), effect any settlement of any pending or threatened proceeding unless such settlement includes an unconditional release of such indemnified party for all liability on claims that are the subject matter of such proceeding and does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) If the indemnification provided for in this Section 6 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Final

Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this subsection (d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this subsection (d). The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company under this Section 6 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section 6 shall be in addition to any liability that the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company (including any person who, with his consent, is named in the Registration Statement as about to become a director of the Company), to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the Act.

(f) The Underwriters severally confirm and the Company acknowledges that the statements with respect to the public offering of the Securities by the Underwriters set forth in the third paragraph, in the fourth sentence of the eleventh paragraph and in the list of the number of Firm Shares purchased by each Underwriter, in each case under the caption “Underwriting” in the Time of Sale Disclosure Package and in the Final Prospectus, are correct and constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Registration Statement, the Time of Sale Disclosure Package or any Prospectus, or any amendment or supplement thereto, any written Testing-the-Waters Communication, or any Issuer Free Writing Prospectus.

7. Representations and Agreements to Survive Delivery. All representations, warranties, and agreements of the Company herein or in certificates delivered pursuant hereto, and the agreements of the several Underwriters and the Company contained in Section 6 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling person thereof, or the Company or any of its officers, directors, or controlling persons, and shall survive delivery of, and payment for, the Securities to and by the Underwriters hereunder.

8. Substitution of Underwriters.

(a) If any Underwriter or Underwriters shall fail to take up and pay for the amount of Firm Shares agreed by such Underwriter or Underwriters to be purchased hereunder, upon tender of such Firm Shares in accordance with the terms hereof, and the amount of Firm Shares not purchased does not aggregate more than 10% of the total amount of Firm Shares set forth in Schedule I hereto, the remaining Underwriters shall be obligated to take up and pay for (in proportion to their respective underwriting obligations hereunder as set forth in Schedule I hereto except as may otherwise be determined by you) the Firm Shares that the withdrawing or defaulting Underwriters agreed but failed to purchase.

(b) If any Underwriter or Underwriters shall fail to take up and pay for the amount of Firm Shares agreed by such Underwriter or Underwriters to be purchased hereunder, upon tender of such Firm Shares in accordance with the terms hereof, and the amount of Firm Shares not purchased aggregates more than 10% of the total amount of Firm Shares set forth in Schedule I hereto, and arrangements satisfactory to you for the purchase of such Firm

Shares by other persons are not made within 36 hours thereafter, this Agreement shall terminate. In the event of any such termination the Company shall not be under any liability to any Underwriter (except to the extent provided in Section 6 hereof) nor shall any Underwriter (other than an Underwriter who shall have failed, otherwise than for some reason permitted under this Agreement, to purchase the amount of Firm Shares agreed by such Underwriter to be purchased hereunder) be under any liability to the Company (except to the extent provided in Section 6 hereof).

If Firm Shares to which a default relates are to be purchased by the non-defaulting Underwriters or by any other party or parties, the Representative and all Underwriters or the Company shall have the right to postpone the First Closing Date for not more than seven business days in order that the necessary changes in the Registration Statement, in the Time of Sale Disclosure Package, in the Final Prospectus or in any other documents, as well as any other arrangements, may be effected. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 8.

9. Termination.

(a) The obligations of the Underwriters hereunder shall be subject to termination at any time at or prior to the First Closing Date or, if the option referred to in Section 3(b) is exercised at or prior to the Second Closing Date, in the absolute discretion of the Representative, on behalf of the Underwriters, if (1) since the time of execution of this Agreement or the earlier respective dates as of which information is given in the Registration Statement, the Final Prospectus and the Permitted Free Writing Prospectuses, if any, there has been any change or any development involving a prospective change in the business, properties, management, financial condition or results of operations of the Company and the Subsidiary taken as a whole, the effect of which change or development is, in the sole judgment of the Representative, so material and adverse as to make it impractical or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Registration Statement, the Final Prospectus and the Permitted Free Writing Prospectuses, if any, (2) since the time of execution of this Agreement, there shall have occurred: (A) a suspension in trading in securities generally on NASDAQ or the New York Stock Exchange; (B) a suspension in trading in the Company’s securities on NASDAQ; (C) the fixing of minimum or maximum prices for trading, or the setting of maximum ranges for prices for securities, on NASDAQ or the New York Stock Exchange by order of the Commission or any other governmental authority having jurisdiction; (D) a general moratorium on commercial banking activities declared by either federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (E) an outbreak or material escalation of hostilities or acts of terrorism involving the United States or a declaration by the United States of a national emergency or war; or (F) any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (E) or (F), in the sole judgment of the Representative, makes it impractical or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Registration Statement, the Final Prospectus and the Permitted Free Writing Prospectuses, if any, or (3) since the time of execution of this Agreement, there shall have occurred any downgrading, or any notice or announcement shall have been given or made of: (Y) any intended or potential downgrading or (Z) any watch, review or possible change that does not indicate an affirmation or improvement in the rating accorded any securities of or guaranteed by the Company or its Subsidiary by any “nationally recognized statistical rating organization,” as that term is defined in Rule 436(g)(2) under the Act. Any such termination shall be without liability of any party to any other party except that the provisions of Sections 4(g) and 6 hereof shall at all times be effective and shall survive such termination.

(b) If you elect to terminate this Agreement as provided in this Section, the Company shall be notified promptly by you by telephone, confirmed by letter.

10. Default by the Company. If the Company shall fail at the First Closing Date to sell and deliver the number of Securities which it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any Underwriter. No action taken pursuant to this Section shall relieve the Company so defaulting from liability, if any, in respect of such default.

11. Notices. Except as otherwise provided herein, all communications hereunder shall be in writing and, if to the Underwriters, shall be mailed or delivered to the Underwriters c/o Canaccord Genuity Inc., 00 Xxxx Xxxxxx, 00xx Xxxxx, Xxxxxx, Xxxxxxxxxxxxx 00000, with a copy to Xxxxx Day, 0000 Xxxxxxxxxxx Xxxx, Xxxx Xxxx, Xxxxxxxxxx 00000, Attention: Xxxxxxx Xxxxx, Esq.; if to the Company, shall be mailed or delivered to it at x/x Xxxxxxxx Xxxxx, Xxx., 00000

Ladies and Gentlemen:

Sunshine Heart, Inc., a Delaware corporation (the “Company”), intends to engage in a public offering (the “Offering”) of its common stock (the “Common Stock”). As an inducement to the underwriters (the “Underwriters”) to execute an underwriting agreement (the “Underwriting Agreement”) providing for the Offering, the undersigned hereby agrees that without, in each case, the prior written consent of Canaccord Genuity Inc. (“Canaccord”) during the period specified in the next succeeding paragraph (the “Lock-Up Period”), the undersigned will not, and will cause any member of the undersigned’s “immediate family” not to, (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, make any short sale or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into, exercisable or exchangeable for or that represent the right to receive Common Stock (including without limitation, Common Stock or any other shares of capital stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant) whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition (collectively, the “Undersigned’s Securities”), or exercise any right with respect to the registration of any of the Undersigned’s Securities, or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Undersigned’s Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Securities even if such securities would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Securities or with respect to any security that includes, relates to, or derives any significant part of its value from such Undersigned’s Securities. For purposes of this Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

The Lock-Up Period will commence on the date of this Agreement and continue and include the date 90 days after the date of the final prospectus used to sell Common Stock in the Offering pursuant to the Underwriting Agreement, to which you are or expect to become parties.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Securities (i) as a bona fide gift or gifts, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, (iii) by will or intestacy to the undersigned’s legal representative, heir or legatee, or (iv) if the undersigned is a partnership or corporation or similar entity, as a distribution to partners or stockholders of the undersigned; provided, in each case, that (x) such transfer shall not involve a disposition for value, (y) the transferee agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Agreement, and (z) no filing by any party under Section 16(a) of the Exchange Act, shall be required or shall be made voluntarily in connection with such transfer.

In addition, the foregoing restrictions shall not apply to (i) the exercise of stock options granted pursuant to the Company’s equity incentive plans; provided that it shall apply to any of the Undersigned’s Securities issued upon such exercise, or (ii) the establishment of any contract, instruction or plan (a “Plan”) that satisfies all of the requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act; provided that no sales of the Undersigned’s Securities shall be made pursuant to such a Plan prior to the expiration of the Lock-Up Period, and such a Plan may only be established if no public announcement of the establishment or existence thereof and no filing with the Securities and Exchange Commission or other regulatory authority in respect thereof or transactions thereunder or contemplated thereby, by the undersigned, the Company or any other person, shall be required, and no such announcement or filing is made voluntarily, by the undersigned, the Company or any other person, prior to the expiration of the Lock-Up Period.

If the undersigned is an officer or director of the Company, (i) Canaccord agrees that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of the Undersigned’s Securities, Canaccord will notify the Company of the impending release or waiver, and (ii) the Company (in accordance with the provisions of the Underwriting Agreement) will announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by Canaccord hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if both (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this Agreement that are applicable to the transferor to the extent and for the duration that such terms remain in effect at the time of the transfer.

In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to decline to make any transfer of shares of Common Stock if such transfer would constitute a violation or breach of this Agreement.

In addition, the undersigned agrees that, without the prior written consent of Canaccord, it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any Common Stock or any security convertible into or exercisable or exchangeable for Common Stock.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned understands that the undersigned shall be released from all obligations under this Agreement if (i) the Company notifies the Underwriters that it does not intend to proceed with the Offering, (ii) the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder, or (iii) the Offering is not completed by June 30, 2013.

The undersigned understands that the Underwriters are entering into the Underwriting Agreement and proceeding with the Offering in reliance upon this Agreement.

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
