Exhibit 10.1

PROMISSORY NOTE

$30,000,000		May 21, 2010

     FOR VALUE RECEIVED, each of ATS Medical, Inc., a Minnesota corporation (“ATS”), and its subsidiaries signatory hereto (collectively “Borrower”), jointly and severally promises to pay to the order of Medtronic, Inc., a Minnesota corporation (“Lender”), at its office located at 710 Medtronic Parkway, Minneapolis, Minnesota, or at such other place as may be designated from time to time by the holder hereof, in lawful money of the United States of America, the principal sum of Thirty Million Dollars ($30,000,000), or such lesser amount as may be advanced to Borrower hereunder, together with interest on the unpaid principal balance hereof from the date hereof until this Promissory Note (this “Note”) is fully paid, at an annual rate of interest that shall at all times be equal to the Interest Rate (as defined below), calculated on the basis of actual number of days elapsed in a 365 day year. As used herein, “Interest Rate” shall mean the annual rate of interest equal to 10%. Notwithstanding anything to the contrary contained in this Note, if during any period for which interest is computed hereunder, the amount of interest computed on the basis provided for in this Note, together with all fees, charges and other payments which are treated as interest under applicable law, as provided for herein or in any other document executed in connection herewith, would exceed the amount of such interest computed on the basis of the Highest Lawful Rate (as defined below), Borrower shall not be obligated to pay, and Lender shall not be entitled to charge, collect, receive, reserve or take interest in excess of the Highest Lawful Rate, and during any such period the interest payable hereunder shall be computed on the basis of the Highest Lawful Rate. As used herein, “Highest Lawful Rate” means the maximum non-usurious rate of interest, as in effect from time to time, which may be charged, contracted for, reserved, received or collected by Lender in connection with this Note under applicable law.

Advances

Following the date of this Note until the termination of the Merger Agreement (as defined below), the Borrower may request an advance under this Note (each, an “Advance”), provided, that the aggregate unpaid principal amount of all outstanding loans hereunder shall not exceed $30,000,000 (the “Commitment”) at any time. Upon five (5) Business Days written notification from Lender to Borrower that the principal amount outstanding hereunder exceeds the Commitment, the Borrower shall pay to the Lender, in cash, the amount of such excess. Each time the Borrower desires to obtain an Advance (which shall not be more often than one time per month), such request shall be (a) in writing, (b) signed by the Chief Financial Officer of the Borrower, (c) faxed to the Lender at (763)  ###-###-####, Attention: Treasury Department, and (d) e-mailed to Lender at ***@***, and must be given so as to be received by the Lender not later than 11:00 a.m., Minneapolis time, on the date which is three (3) Business Days before the date of the requested Advance. Each request for an Advance shall specify (i) the borrowing date (which shall be a Business Day), (ii) the amount of such Advance (which shall be in increments of $1,000,000), and (iii) the wire transfer instructions for the Advance. Any request for an Advance shall be deemed to be a representation by the Borrower that no event has occurred and is continuing, or will result from such Advance, which constitutes

an Event of Default or any event which, with the giving of notice to the Borrower or lapse of time, or both, would constitute an Event of Default (“Default”). If the foregoing and following conditions precedent have been satisfied:

     (a) no Event of Default or Default exists or would result from such Advance;

     (b) before and immediately after giving effect to such Advance, all of the representations and warranties of the Borrower in this Note (to the extent, if at all, such representations and warranties have been modified by disclosures made in writing to, and approved in writing by, the Lender) shall be true and correct in all material respects as though made on the date of such Advance (other than representations and warranties that relate to a specific date, which shall have been true and correct in all material respects as of such date);

     (c) the Borrower has not made any material misrepresentation or omission in disclosures to the Lender in connection with the Merger Agreement;

     (d) the Borrower has not experienced any Material Adverse Effect (as defined in the Merger Agreement); and

     (e) to the extent requested by Lender, all necessary filings have been made in each applicable jurisdiction and all other actions, including without limitation, delivery of stock certificates to Lender, have occurred to perfect Lender’s security interest in the Collateral (as defined in the Security Agreement),

then Lender shall make the amount of the requested Advance available to the Borrower at the account specified in the advance request, in immediately available funds not later than 5:00 p.m., Minneapolis time, on the requested borrowing date. The Borrower shall be obligated to repay all Advances made by Lender that the Lender reasonably determines were requested on behalf of the Borrower notwithstanding the fact that the person requesting the same was not in fact authorized to do so. The Lender shall enter in its records the amount of each Advance hereunder, and the payments made hereon, and such records shall be deemed conclusive evidence of the subject matter thereof, absent manifest error. This Note is a multiple advance facility, but it is not a revolving facility, and therefore the Borrower may not borrow, repay and reborrow amounts hereunder.

Payment of Interest and Principal

     Interest shall be payable monthly, in arrears, on the first day of each month following funding of this Note. The entire unpaid principal balance of this Note, together with all accrued and unpaid interest thereon, shall be due and payable in full twenty-four months following the termination for any reason of the Merger Agreement (defined below) (“Expiration Date”). Upon final payment of this Note (whether upon the Expiration Date or upon prepayment in full), Borrower shall pay, in addition to the then outstanding principal and accrued but unpaid interest, a final payment equal to six percent (6%) of the original principal balance of this Note.

     For purposes of this Note, “Merger Agreement” shall mean that certain Agreement and Plan of Merger dated April 28, 2010 among Pilgrim Merger Corporation, Lender and ATS.

Prepayment

     The principal balance of this Note may be prepaid in whole or in part from time to time on any interest payment date, without penalty or premium, if Borrower gives Lender at least three (3) Business Days prior notice to Lender.

Manner of Payments

     Payments and prepayments of principal of, and interest on, this Note and all fees, expenses and other obligations under this Note, the Security Agreements (as defined below), and any other documents executed in connection herewith, excluding the Merger Agreement and the documents executed in connection therewith, (collectively, the “Loan Documents”) shall be made without set-off or counterclaim in immediately available funds not later than 2:00 p.m., Minneapolis time, on the dates due wired to the following account of the Lender pursuant to the following instructions:

Wells Fargo Bank
San Francisco CA
SWIFT code is WFBIUS6S
ABA: 121000248
Acct. Name: Medtronic Inc
Acct #0000033443

Funds received on any day after such time shall be deemed to have been received on the next Business Day (as defined below). Whenever any payment to be made hereunder or under any other Loan Document shall be stated to be due on a day which is not a Business Day (as defined below), such payment shall be made on the next succeeding business day and such extension of time shall be included in the computation of any interest or fees. As used herein, “Business Day” means a day of the year (other than a Saturday, Sunday, legal holiday or other day on which banking institutions in Minnesota are authorized or required by law to close) in which Lender is open for the purpose of conducting commercial business.

Application of Payments

     Any payment hereunder shall be applied first to the payment of outstanding reasonable costs and expenses payable pursuant to this Note, second to accrued interest and then to the reduction of principal.

Use of Proceeds

     The proceeds of any Advance shall be used solely (i) to redeem the approximately $22,400,000 (principal amount plus interest) owed on the Borrower’s 6% Convertible Senior Notes due in 2025, (ii) to repay the approximately $3,100,000 (principal amount plus interest, prepayment fees and final payment fees) outstanding on the term loan from Silicon Valley Bank,

(iii) prior to the termination of the Merger Agreement, to finance working capital, and/or (iv) after the termination of the Merger Agreement, for general corporate purposes in the ordinary course of business consistent with past practice. The Borrower shall not use the proceeds of any Advance under this Note to pay dividends or make other distributions with respect to its capital stock to its shareholders.

Security

     This Note is secured by a Security Agreement (“Security Agreement”) and a Pledge Agreement (“Pledge Agreement”) each dated the date hereof between Lender and Borrower.

Representations and Warranties

     To induce the Lender to accept this Note and to advance the proceeds hereof to the Borrower, the Borrower represents and warrants to Lender as follows:

     (a) Power. Each Borrower has all requisite power and authority to carry on its businesses as now conducted, to enter into the Loan Documents to which it is a party and to perform its obligations under the Loan Documents to which it is a party.

     (b) Authorization and Validity. The execution, delivery and performance by each Borrower of the Loan Documents to which such Borrower is a party have been duly authorized by all necessary company action by such Borrower, and the Loan Documents constitute the legal, valid and binding obligations of the Borrower thereto, enforceable against such Borrower in accordance with their respective terms, subject to limitations as to enforceability which might result from bankruptcy, insolvency, moratorium and other similar laws affecting creditors’ rights generally and subject to limitations on the availability of equitable remedies.

     (c) No Conflict; No Default. The execution, delivery and performance by each of the Borrower of the Loan Documents to which such Borrower is a party, including such Borrower’s receipt and use of the proceeds of the borrowing evidenced by this Note, will not (a) violate any provision of any law, statute, rule or regulation or any order, writ, judgment, injunction, decree, determination or award of any court, governmental agency or arbitrator presently in effect having applicability to such Borrower, (b) violate or contravene any provisions of such Borrower’s organizational or governing documents, or (c) result in a breach of or constitute a default under any indenture, loan or credit agreement or any other agreement, lease or instrument to which such Borrower is a party or by which such Borrower or any of its properties may be bound or result in the creation of any lien, security interest or other encumbrance (collectively, “Liens”) on any of its assets, other than Liens in favor of Lender and other than Permitted Liens (as defined in the Security Agreement). None of the Borrower is in default under or in violation of any such law, statute, rule or regulation, order, writ, judgment, injunction, decree, determination or award or any such indenture, loan or credit agreement or other agreement, lease or instrument in any material respect which would be expected to have a material adverse effect.

     (d) Financial Statements and Condition. The financial statements of the Borrower, as heretofore furnished to Lender by the Borrower, fairly present in all material respects the financial condition of each Borrower as of the dates specified therein and the results of its operations and changes in financial position for the periods ended as of the dates specified therein.

     (e) Subsidiaries. Other than as set forth on Schedule 1 hereto, no Borrower has any subsidiary. All amounts paid, payable to or advanced by Borrower directly to or for the benefit of any subsidiary that has not executed and delivered to Lender such joinders, guaranties, security agreements, other documents and other items as Lender requires have been used solely for legitimate general operating expenses of the applicable subsidiary.

     (f) Completeness of Disclosures. No representation or warranty by any Borrower contained herein or in any other Loan Document, or in any certificate or other document furnished heretofore or concurrently with the signing of this Note or any other Loan Document by any Borrower to the Lender in connection with the transactions contemplated hereunder or under any other Loan Document, when taken together as a whole and in light of the circumstances in which such representation or warranty was made, contains any untrue statement of a material fact or omits to state a material fact which would prevent or materially inhibit any Borrower from performing this Note or any other Loan Document according to its terms.

     (g) Survival of Representations. All of the representations and warranties set forth in the immediately preceding sections are true as of the date of this Note and the date of each Advance by Lender hereunder and shall survive execution and delivery of this Note until all the obligations under the Loan Documents shall have been satisfied in full.

Each of the foregoing representations and warranties shall be deemed to be repeated and reaffirmed on and as of the date any Advance is made hereunder by Lender.

No Waiver

     No failure on the part of Lender to exercise and no delay in exercising any power or right hereunder or under this Note or any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any power or right preclude any other or further exercise thereof or the exercise of any other power or right. The remedies herein and in any other instrument, document or agreement delivered or to be delivered to Lender hereunder or in connection herewith are cumulative and not exclusive of any remedies provided by law. No notice to or demand on Borrower not required hereunder or under any other Loan Document shall in any event entitle Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the right of Lender or the holder of this Note to any other or further action in any circumstances without notice or demand. No amendment, modification or waiver of any provision of this Note or any other Loan Document or consent to any departure by Borrower therefrom shall be effective unless the same shall be in writing and signed by Lender, and then such amendment, modifications, waiver or consent shall be effective only in the specific instances and for the specific purpose for which given.

     THIS CERTIFIES THAT, for value received, Medtronic, Inc., a Minnesota corporation or its permitted assigns (the “Holder”) is entitled to subscribe for and purchase up to                      fully paid and nonassessable shares (the “Shares”) of common stock, par value $0.01 per share (the “Common Stock”), of ATS Medical, Inc., a Minnesota corporation (the “Company”), at $2.61 per share (such price and such other price as shall result, from time to time, from the adjustments specified in Section 4 hereof is herein referred to as the “Warrant Price”), upon the terms and subject to the conditions hereinafter set forth. This warrant is being issued on this ___ day of                     , 20___ (the “Date of Grant”).

     This warrant is being issued in connection with that certain Promissory Note dated as of                     , 2010 (the “Note”), issued by the Company and certain of its subsidiaries in favor of the Holder. Capitalized terms used and not defined herein shall have the meanings set forth in the Note.

     1. Term. The right represented by this warrant is exercisable, in whole or in part, at any time and from time to time beginning on the Date of Grant (the “Initial Exercise Date”) and ending on the seven-year anniversary of the Date of Grant.

     2. Method of Exercise; Payment; Issuance of New Warrant. Subject to Section 1 hereof, the purchase right represented by this warrant may be exercised by the Holder hereof, in whole or in part and from time to time, at the election of the Holder hereof, as applicable, after the Initial Exercise Date. At the time the Holder elects to exercise this warrant, the Holder shall (i) surrender this warrant (with the notice of exercise substantially in the form attached hereto as Exhibit A-1 duly completed and executed) at the principal office of the Company and by the payment to the Company, by certified or bank check, or by wire transfer to an account designated by the Company (a “Wire Transfer”) of an amount equal to the then applicable Warrant Price multiplied by the number of Shares then being purchased; or (ii) exercise the “net issuance” right provided for in Section 9 hereof. In the event of any exercise of the rights represented by this warrant pursuant to this Section 2, certificates for the shares of stock so

purchased shall be delivered to the Holder hereof as soon as practicable and in any event within three (3) business days after such exercise and, unless this warrant has been fully exercised or expired, a new warrant representing the portion of the Shares, if any, with respect to which this warrant shall not then have been exercised shall also be issued to the Holder hereof as soon as practicable and in any event within such thirty-day period; provided, however, if requested by the Holder of this warrant, the Company shall use reasonable efforts to cause its transfer agent to deliver the certificate representing Shares issued upon exercise of this warrant to a broker or other person (as directed by the Holder exercising this warrant) within the time period required to settle any trade made by the Holder after exercise of this warrant.

The person or persons in whose name(s) any certificate(s) representing shares of Common Stock shall be issuable upon exercise of this warrant shall be deemed to have become the holder(s) of record of, and shall be treated for all purposes as the record holder(s) of, the shares represented thereby (and such shares shall be deemed to have been issued) immediately prior to the close of business on the date or dates upon which this warrant is exercised.

     3. Stock Fully Paid; Reservation of Shares. All Shares that may be issued upon the exercise of the rights represented by this warrant will, upon issuance pursuant to the terms and conditions herein, be fully paid and nonassessable, and free from all preemptive rights and taxes, liens and charges with respect to the issue thereof. During the period within which the rights represented by this warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of the purchase rights evidenced by this warrant, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented by this warrant. If at any time during the term of this warrant the number of authorized but unissued shares of Common Stock shall not be sufficient to permit exercise of this warrant, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes.

     4. Adjustment of Warrant Price and Number of Shares. The number of shares of Common Stock purchasable upon the exercise of this warrant and the Warrant Price shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

          (a) Reclassification or Merger. In case of any reclassification or change of securities of the class issuable upon exercise of this warrant (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), or in case of any merger of the Company with or into another corporation (other than a merger with another corporation in which the Company is the acquiring and the surviving corporation and which does not result in any reclassification or change of outstanding securities issuable upon exercise of this warrant), the Company, or such successor or purchasing corporation, as the case may be, shall (i) in the case of a merger described above, execute and deliver to the Holder a new warrant (in form and substance reasonably satisfactory to the Holder), so that the Holder shall have the right to receive, upon exercise of this warrant, at a total purchase price equal to that payable upon the exercise of the unexercised portion of this warrant, and in lieu of the shares of Common Stock theretofore issuable upon exercise of this warrant, the kind and amount of shares of stock, other securities, money and property receivable upon such

merger or sale by a Holder of the number of shares of Common Stock then purchasable under this warrant and (ii) in the case of a reclassification or change in the securities issuable upon exercise of this warrant described above, the Holder shall have the right to receive, upon exercise of this warrant, at a total purchase price equal to that payable upon the exercise of the unexercised portion of this warrant, and (A) in lieu of the shares of Common Stock theretofore issuable upon exercise of this warrant, the number of shares of Common Stock then purchasable under this warrant upon such reclassification or other change in the securities issuable upon exercise of this warrant or (B) in lieu of cash theretofore issuable upon exercise of this warrant, the amount of cash then issuable under this warrant upon such reclassification or other change in the securities issuable upon exercise of this warrant. Any new warrant shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 4. The provisions of this Section 4(a) shall similarly apply to successive reclassifications, changes, mergers and sales.

          (b) Subdivision or Combination of Shares. If the Company at any time while this warrant remains outstanding and unexpired shall subdivide or combine its outstanding shares of Common Stock, the Warrant Price shall be proportionately decreased and the number of Shares issuable hereunder shall be proportionately increased in the case of a subdivision and the Warrant Price shall be proportionately increased and the number of Shares issuable hereunder shall be proportionately decreased in the case of a combination.

          (c) Stock Dividends and Other Distributions. If the Company at any time while this warrant is outstanding and unexpired shall (i) pay a dividend with respect to Common Stock payable in Common Stock, then the Warrant Price shall be adjusted, from and after the date of determination of shareholders entitled to receive such dividend or distribution, to that price determined by multiplying the Warrant Price in effect immediately prior to such date of determination by a fraction (A) the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such dividend or distribution; or (ii) make any other distribution with respect to Common Stock (except any distribution specifically provided for in Sections 4(a) and 4(b)), then, in each such case, provision shall be made by the Company such that the Holder of this warrant shall receive upon exercise of this warrant a proportionate share of any such dividend or distribution as though it were the holder of the Common Stock as of the record date fixed for the determination of the shareholders of the Company entitled to receive such dividend or distribution.

          (d) Adjustment of Number of Shares. Upon each adjustment in the Warrant Price, the number of shares of Common Stock purchasable hereunder shall be adjusted, rounded up to the nearest whole share, to the product obtained by multiplying the number of Shares purchasable immediately prior to such adjustment in the Warrant Price by a fraction, the numerator of which shall be the Warrant Price immediately prior to such adjustment and the denominator of which shall be the Warrant Price immediately thereafter.

     5. Notice of Adjustments. Whenever the Warrant Price or the number of Shares purchasable hereunder shall be adjusted pursuant to Section 4 hereof, the Company shall make a

certificate signed by its acting chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the Warrant Price and the number of Shares purchasable hereunder after giving effect to such adjustment, and shall cause copies of such certificate to be mailed to the Holder of this warrant.

     6. Fractional Shares. No fractional shares of Common Stock will be issued in connection with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefor based on the product resulting from multiplying the then fair market value of the Common Stock (as determined pursuant to Section 9(c) below) on the date of exercise by such fraction.

     7. Compliance with Act; Disposition of Warrant or Shares of Common Stock.

          (a) Compliance with Act. The Holder of this warrant, by acceptance hereof, agrees that this warrant, and the shares of Common Stock to be issued upon exercise hereof are being acquired for investment and that such Holder will not offer, sell or otherwise dispose of this warrant, or any shares of Common Stock except under circumstances which will not result in a violation of the Securities Act of 1933, as amended (the “Securities Act”), or any applicable state securities laws. Upon exercise of this warrant, unless the Shares being acquired are registered under the Securities Act and any applicable state securities laws or an exemption from such registration is available, the Holder hereof shall confirm in writing that the shares of Common Stock so purchased are being acquired for investment and not with a view toward distribution or resale in violation of the Securities Act and shall confirm such other matters related thereto as may be reasonably requested by the Company. This warrant and all shares of Common Stock issued upon exercise of this warrant (unless registered under the Securities Act and any applicable state securities laws) shall be stamped or imprinted with a legend in substantially the following form:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. THE SECURITIES REPRESENTED HEREBY MAY NOT BE TRANSFERRED UNLESS (I) SUCH SECURITIES HAVE BEEN REGISTERED FOR SALE PURSUANT TO THE SECURITIES ACT OR (II) THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO IT THAT SUCH TRANSFER MAY LAWFULLY BE MADE WITHOUT REGISTRATION UNDER THE SECURITIES ACT OR QUALIFICATION UNDER APPLICABLE STATE SECURITIES LAWS.

Said legend shall be removed by the Company, upon the request of a Holder, at such time as the restrictions on the transfer of the applicable security have terminated.

          (b) Disposition of Warrant or Shares. This warrant and any shares of Common Stock acquired pursuant to the exercise or conversion of this warrant may be transferred only pursuant to a registration statement filed under the Securities Act or an exemption from such

registration. Subject to such restrictions, the Company shall transfer this warrant from time to time upon the books to be maintained by the Company for that purpose, upon surrender thereof for transfer properly endorsed or accompanied by appropriate instructions for transfer and such other documents as may be reasonably required by the Company, including, if required by the Company, an opinion of counsel to the effect that such transfer is exempt from the registration requirements of the Securities Act to establish that such transfer is being made in accordance with the terms hereof, and a new warrant shall be issued to the transferee and the surrendered warrant shall be canceled by the Company. Each certificate representing this warrant or the shares of Common Stock thus transferred (except a transfer pursuant to Rule 144 or 144A) shall bear a legend as to the applicable restrictions on transferability in order to ensure compliance with such laws, unless such legend is not required in order to ensure compliance with such laws. The Company may issue stop transfer instructions to its transfer agent in connection with such restrictions.

          (c) Applicability of Restrictions. Neither any restrictions of any legend described in this warrant nor the requirements of Section 7(b) above shall apply to any transfer of, or grant of a security interest in, this warrant (or the Common Stock obtainable upon exercise hereof) or any part hereof (i) to a partner of the Holder if the Holder is a partnership or to a member of the Holder if the Holder is a limited liability company, (ii) to a partnership of which the Holder is a partner or to a limited liability company of which the Holder is a member, or (iii) to any affiliate of the Holder if the Holder is a corporation; provided, however, in any such transfer, if applicable, the transferee shall on the Company’s request agree in writing to be bound by the terms of this warrant as if an original Holder hereof.

     8. Rights as Shareholders; Information. No Holder of this warrant, as such, shall be entitled to vote or receive dividends or be deemed the holder of Common Stock issuable upon the exercise hereof for any purpose, nor shall anything contained herein be construed to confer upon the Holder of this warrant, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until this warrant shall have been exercised and the Shares purchasable upon the exercise hereof shall have become deliverable, as provided herein.

     9. Right to Convert Warrant into Stock: Net Issuance.

          (a) Right to Convert. In addition to and without limiting the rights of the Holder under the terms of this warrant, the Holder shall have the right to convert this warrant or any portion thereof (the “Conversion Right”) into shares of Common Stock as provided in this Section 9 at any time or from time to time during the term of this warrant. Upon exercise of the Conversion Right with respect to a particular number of shares subject to this warrant (the “Converted Warrant Shares”), the Company shall deliver to the Holder (without payment by the Holder of any exercise price or any cash or other consideration) that number of shares of fully paid and nonassessable Common Stock as is determined according to the following formula:

     X = (B — A) divided by Y

Where: X = the number of shares of Common Stock that shall be issued to Holder
Y = the fair market value of one share of Common Stock
A = the aggregate Warrant Price of the specified number of Converted Warrant Shares immediately prior to the exercise of the Conversion Right (i.e., the number of Converted Warrant Shares multiplied by the Warrant Price)
B = the aggregate fair market value of the specified number of Converted Warrant Shares (i.e., the number of Converted Warrant Shares multiplied by the fair market value of one Converted Warrant Share)

If shares of Common Stock are issuable pursuant to this Section 9, no fractional shares shall be issuable upon exercise of the Conversion Right, and, if the number of shares to be issued determined in accordance with the foregoing formula is other than a whole number, the Company shall pay to the Holder an amount in cash equal to the fair market value of the resulting fractional share on the Conversion Date (as hereinafter defined).

          (b) Method of Exercise. The Conversion Right may be exercised by the Holder by the surrender of this warrant at the principal office of the Company together with a written statement (which may be in the form of Exhibit A-1) specifying that the Holder thereby intends to exercise the Conversion Right and indicating the number of shares subject to this warrant which are being surrendered (referred to in Section 9(a) hereof as the Converted Warrant Shares) in exercise of the Conversion Right. Such conversion shall be effective upon receipt by the Company of this warrant together with the aforesaid written statement, or on such later date as is specified therein (the “Conversion Date”). Certificates for the shares issuable upon exercise of the Conversion Right and, if applicable, a new warrant evidencing the balance of the shares remaining subject to this warrant, shall be issued as of the Conversion Date and shall be delivered to the Holder within thirty (30) days following the Conversion Date.

          (c) Determination of Fair Market Value. For purposes of this Section 9, “fair market value” of a share of Common Stock as of a particular date (the “Determination Date”) shall mean: (i) if traded on a securities exchange, the fair market value of the Common Stock shall be deemed to be the average of the closing prices of the Common Stock on such exchange over the five trading days immediately prior to the Determination Date as reported by Bloomberg Financial Markets (or a comparable reporting service of national reputation selected by the Company and reasonably acceptable to the Holder if Bloomberg Financial Markets is not then reporting sales prices of such security) (collectively, “Bloomberg”); (ii) if traded on a market that is not a securities exchange, the fair market value of the Common Stock shall be deemed to be the average of the closing bid prices of the Common Stock over the five trading days immediately prior to the Determination Date as reported by Bloomberg; and (iii) if there is no public market for the Common Stock, then fair market value shall be determined by the Board of Directors of the Company in good faith.

          (d) Automatic Exercise: If this Warrant would terminate or expire but for the application of this Section 9(d), then if the fair market value of one share of Common Stock exceeds the Warrant Price this Warrant shall be deemed automatically converted pursuant to this Section 9 immediately prior to such termination or expiration.

     10. Representations and Warranties. The Company represents and warrants to the Holder of this warrant as follows:

          (a) This warrant has been duly authorized and executed by the Company and is a valid and binding obligation of the Company enforceable in accordance with its terms, subject to laws of general application relating to bankruptcy, insolvency and the relief of debtors and the rules of law or principles at equity governing specific performance, injunctive relief and other equitable remedies.

          (b) The Shares have been duly authorized and reserved for issuance by the Company and, when issued in accordance with the terms hereof, will be validly issued, fully paid and nonassessable and free from preemptive rights.

          (c) The execution and delivery of this warrant are not, and the issuance of the Shares upon exercise of this warrant in accordance with the terms hereof will not be, inconsistent with the Company’s articles of incorporation or bylaws, do not and will not contravene any law, governmental rule or regulation, judgment or order applicable to the Company, and do not and will not conflict with or contravene any provision of, or constitute a default under, any indenture, mortgage, contract or other instrument of which the Company is a party or by which it is bound or require the consent or approval of, the giving of notice to, the registration or filing with or the taking of any action in respect of or by, any federal, state or local government authority or agency or other person, except for the filing of notices pursuant to federal and state securities laws, which filings will be effected by the time required thereby.

     11. Registration Rights.

          (a) If requested by the Holder (the “Demand Registration Right”), the Company shall prepare and, as soon as practicable but in no event later than 30 calendar days after receiving such a request from the Holder (the “Filing Deadline”), file with the Commission a Registration Statement on Form S-3 (the “Registration Statement”) covering the resale of all of the shares of Common Stock issuable upon exercise of any Warrants issued to the Holder under the Note on or before the date of such demand (the “Registrable Securities”). The Holder shall have only one Demand Registration Right, and such Demand Registration Right shall apply to all Registrable Securities issuable to Holder on or before the date of the demand upon the exercise of the Warrants issued by the Company to the Holder in connection with the transactions contemplated by the Note.

          (b) The Registration Statement prepared pursuant hereto shall register the Registrable Securities for resale, including the number of shares of Common Stock issuable upon exercise of the Warrants by the Holder from time to time in accordance with the methods of distribution elected by such Holder. The Company shall use its best efforts to have the Registration Statement declared effective by the Commission as soon as practicable, but not later than 90 calendar days after the Filing Deadline (the “Effectiveness Deadline”); provided, however, that if the Commission reviews the Registration Statement and requires the Company to make modifications thereto, then the Effectiveness Deadline shall be extended to 120 calendar days after the Filing Deadline. In the event that, before the Registration Statement is declared

effective, the offices of the Securities and Exchange Commission are closed due to acts of God, war or terror (or similar circumstances), the Effectiveness Deadline will be extended by a number of days equal to the days of any such closure.

     12. Modification and Waiver. This warrant and any provision hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the party against which enforcement of the same is sought.

     13. Notices. Any notice, request, communication or other document required or permitted to be given or delivered to the Holder hereof or the Company shall be delivered, or shall be sent by certified or registered mail, postage prepaid, to each such Holder at its address as shown on the books of the Company or to the Company at the address indicated therefore on the signature page of this warrant.

     14. Binding Effect on Successors. This warrant shall be binding upon any corporation succeeding the Company by merger, consolidation or acquisition of all or substantially all of the Company’s assets, and all of the obligations of the Company relating to the Common Stock issuable upon the exercise or conversion of this warrant shall survive the exercise, conversion and termination of this warrant and all of the covenants and agreements of the Company shall inure to the benefit of the successors and assigns of the Holder hereof.

     15. Lost Warrants or Stock Certificates. The Company covenants to the Holder hereof that, upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this warrant or any stock certificate and, in the case of any such loss, theft or destruction, upon receipt of an indemnity reasonably satisfactory to the Company, or in the case of any such mutilation upon surrender and cancellation of such warrant or stock certificate, the Company will make and deliver a new warrant or stock certificate, of like tenor, in lieu of the lost, stolen, destroyed or mutilated warrant or stock certificate.

     16. Descriptive Headings. The descriptive headings of the various sections of this warrant are inserted for convenience only and do not constitute a part of this warrant. The language in this warrant shall be construed as to its fair meaning without regard to which party drafted this warrant.

     17. Governing Law. This warrant shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the laws of the State of Minnesota.

     18. Remedies. In case any one or more of the covenants and agreements contained in this warrant shall have been breached, the Holder hereof (in the case of a breach by the Company), or the Company (in the case of a breach by the Holder), may proceed to protect and enforce their or its rights either by suit in equity and/or by action at law, including, but not limited to, an action for damages as a result of any such breach and/or an action for specific performance of any such covenant or agreement contained in this warrant.

     19. No Impairment of Rights. The Company will not, by amendment of its articles of incorporation or through any other means, avoid or seek to avoid the observance or performance

of any of the terms of this warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder of this warrant against impairment.

     20. Severability. The invalidity or unenforceability of any provision of this warrant in any jurisdiction shall not affect the validity or enforceability of such provision in any other jurisdiction, or affect any other provision of this warrant, which shall remain in full force and effect.

     21. Recovery of Litigation Costs. If any legal action or other proceeding is brought for the enforcement of this warrant, or because of an alleged dispute, breach, default, or misrepresentation in connection with any of the provisions of this warrant, the successful or prevailing party or parties shall be entitled to recover reasonable attorneys’ fees and other costs incurred in that action or proceeding, in addition to any other relief to which it or they may be entitled.

     22. Entire Agreement; Modification. This warrant constitutes the entire agreement between the parties pertaining to the subject matter contained in it and supersedes all prior and contemporaneous agreements, representations, and undertakings of the parties, whether oral or written, with respect to such subject matter.
