RECITALS:

WHEREAS, the Company proposes to authorize the sale and issuance of Secured Promissory Notes in the form attached hereto as Exhibit A (each a “Note” and collectively the “Notes”); and

WHEREAS, the Holders desire to purchase, severally and not jointly, the Notes and the Company desires to issue and sell such Notes to the Holders, on the terms and conditions set forth herein; and

WHEREAS, in connection with the sale and issuance of the Notes, the Company also proposes to issue to the Holders thereof warrants to purchase shares of the Company’s Common Stock, par value $0.01 per share (each a “Warrant” and collectively the “Warrants”).

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual promises hereinafter set forth, the parties hereto agree as follows:

The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by the Company’s most recently filed periodic report under the Exchange Act (such date, the “Evaluation Date”) and concluded that such controls were ineffective as of the Evaluation Date. The Company presented in its most recently filed periodic report under the Exchange Act such conclusion of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no changes in the Company’s internal control over financial reporting (as such term is defined in the Exchange Act) that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting, and no significant deficiencies or material weakness in internal controls over financial reporting, other than as disclosed in the Company’s SEC Filings, have been identified.

The Company is not in violation of any applicable statute, law or regulation relating to the environment or occupational health and safety, and no expenditures are or are reasonably anticipated to be required in order to comply with any such existing statute, law or regulation. During the period that the Company has owned or leased its properties and facilities, (i) there have been no disposals, releases or threatened releases of Hazardous Materials (as defined below) by the Company on, from or under such properties or facilities, and (ii) other than normal office products and cleaning supplies, it has not used, generated, manufactured or stored on, under or about such properties or facilities or transported to or from such properties or facilities any Hazardous Materials. For purposes of this Section, the terms “disposal,” “release” and “threatened release” shall have the definitions assigned thereto by the Comprehensive Environmental Response, Compensation and Liability Act of 1980, 42 U.S.C. Section 9601, et seq. as amended (“CERCLA”). For the purposes of this Section, “Hazardous Materials” shall mean any hazardous or toxic substance, material or waste, which is regulated under, or defined as a “hazardous substance,” “pollutant,” “contaminant,” “toxic chemical,” “hazardous material,” “toxic substance” or

“hazardous chemical” under (1) CERCLA; (2) the Emergency Planning and Community Right-to-Know Act, 42 U.S.C. Section 11001, et seq.; (3) the Hazardous Materials Transportation Act, 49 U.S.C. Section 1801, et seq.; (4) the Toxic Substance Control Act, 15 U.S.C. Section 2601, et seq.; (5) the Occupational Safety and Health Act of 1970, 29 U.S.C. Section 651, et seq.; (6) regulations promulgated under any of the above statutes; or (7) any applicable state or local statute, ordinance, rule or regulation that has a scope or purpose similar to those statutes identified above.

The Collateral has been kept in reasonable condition and repair in the ordinary course of business, and is reasonably fit and suitable for the purposes for which they it is being used and, to the extent applicable, is believed by the Company to conform in all material respects with applicable ordinances, regulations and laws.

The Company possesses from the appropriate regulatory agency, commission, board, government body and authority, whether state, local, federal or foreign, all licenses, permits, certifications, authorizations, approvals, franchises and rights which (i) are necessary for it to engage in the business currently conducted by it, and (ii) if not possessed by the Company, would have a Material Adverse Effect. A list of all material licenses, permits, approvals and similar rights currently in effect is set forth on Schedule 5.19.

The Company has in full force and effect fire and casualty insurance policies and insurance against other hazards, risks, and liabilities to persons and property to the extent and in the manner customary for similarly situated companies in similar businesses, and such insurance policies have been issued by financially sound, duly licensed and reputable insurers.

No material labor dispute exists or, to the knowledge of the Company, is imminent with respect to any of the employees of the Company which could reasonably be expected to result in a Material Adverse Effect.

Other than the declaration of effectiveness by the Commission of any Registration Statement required to be filed pursuant to this Agreement, no consent, approval, authorization or order of any court, governmental agency or body or arbitrator having jurisdiction over the Company, or any of its affiliates, the NASD, the OTC Bulletin Board or the Company’s shareholders is required for execution of the Transaction Agreements, including, without limitation the issuance and sale of the Notes, Warrants and Warrant Shares and the performance of the Company’s obligations under the Transaction Agreements. The Company has obtained all required waivers of preemption rights in connection with the issuance of the Notes and Warrants.

Subject in part to the accuracy of the Holders’ representations and warranties in Section 6, the offer, sale, and issuance of the Notes and Warrants in compliance with the terms of this Agreement

constitute transactions exempt from the registration requirements of Section 5 of the Securities Act and all applicable state securities laws. Neither the Company nor any agent on its behalf has solicited or will solicit any offers to sell or has offered to sell or will offer to sell all or any part of the Notes or Warrants to any person or persons so as to bring the sale of such Notes and Warrants by the Company within the registration provisions of the Securities Act or any applicable state securities laws.

With the exception of ▇▇▇▇▇-▇▇▇▇▇▇ Capital Group LLC, the Company has not engaged any brokers, finders, or agents. The Holders have not incurred, and will not incur, directly or indirectly, as a result of any action taken by the Company, any liability for brokerage or finders’ fees or agents’ commissions or any similar charges in connection with the Transaction Agreements.

The Company’s Common Stock is registered pursuant to Section 12(b) or 12(g) of the Exchange Act and quoted on the OTC Bulletin Board under the symbol “MCVI.OB.” The Company has taken no action designed to, or which to its knowledge is likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act nor has the Company received any notification that the Commission is contemplating terminating such registration, nor has the Company received any oral or written notice that its Common Stock will cease to be quoted on the OTC Bulletin Board. The Company is not aware of any event or circumstance that will or may cause the Company Common Stock to cease to be quoted on the OTC Bulletin Board.

The Company represents that the foregoing representations and warranties are true and correct as of the date hereof, and, unless the Company otherwise notifies the Holders in writing prior to the Effective Date, shall be true and correct as of the Effective Date.

The Company has made available to the Holders all the information that the Holders have requested in connection with their decisions as to whether to purchase the Notes and Warrants pursuant to this Agreement. Neither the Transaction Agreements nor any other exhibits, schedules, documents or certificates delivered in connection with the Transaction Agreements, which shall include the Company’s SEC Filings, when taken as a whole, contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained herein or therein not misleading in light of the circumstances under which they were made.

Each Holder, severally and not jointly, hereby represents and warrants to the Company as of the date hereof and as of each Closing Date with respect to each purchase of Notes by such Holder as follows (such representations and warranties do not lessen or obviate the representations and warranties of the Company set forth in this Agreement):

Holder is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization with full right, corporate or partnership power and authority to enter into and to consummate the transactions contemplated by the Transaction Agreements and otherwise to carry out its obligations hereunder and thereunder. The execution, delivery and performance by Holder of the transactions contemplated by the Transaction Agreements have been duly authorized by all necessary corporate or similar action on the part of such Holder. Each Transaction Agreement to which it is a party has been duly executed by Holder, and when delivered by Holder in accordance with the terms hereof, will constitute the valid and legally binding obligation of the Holder, enforceable against it in accordance with its terms, except (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law.

(a) Information about the Company. The Holder has had access to and has been furnished with information relating to the business, operations and financial condition of the Company as well as this Agreement and the transactions contemplated hereby, and has had an adequate opportunity to ask such questions of, and receive answers from, the Company or an agent or representative of the Company, regarding the Company and its business to the extent deemed necessary by the Holder in order to form a decision concerning an investment in the Company.

(b) Holder Bears Economic Risk. Holder has substantial experience in evaluating and investing in highly speculative securities and as such is capable of evaluating the merits and risks of its investment in the Company. Holder understands that the Company has no present intention of registering the Notes, Warrants or any of the Warrant Shares, excepts as provided in Section 8 of this Agreement. Holder also understands that there is no assurance that any exemption from registration under the Securities Act will be available and that, even if available, such exemption may not allow Holder to transfer all or any portion of the Notes, Warrants or the Warrant Shares under the circumstances, in the amounts or at the times Holder might propose.

(c) Acquisition for Own Account. Holder is acquiring the Notes and Warrants, and will acquire the Warrant Shares, for Holder’s own account for investment only, and not with a view towards their public distribution.

(d) Holder Can Protect Its Interest. Holder represents that by reason of its, or of its management’s, business or financial experience, Holder has the capacity to protect its own interests in connection with the transactions contemplated in this Agreement and the Security Documents. Further, Holder is aware of no publication of any advertisement in connection with the transactions contemplated in the Agreement.

(e) Accredited Holder. Holder represents that it is an accredited Holder within the meaning of Regulation D of the Securities Act.

(f) Residence. Each Holder is a bona fide resident of, or entity duly formed pursuant to the laws of, and is domiciled in, the state or country set forth in his, her or its address as provided below.

Holder represents that the foregoing representations and warranties are true and correct as of the date hereof, and, unless Holder otherwise notifies the Company in writing prior to the Effective Date, shall be true and correct as of the Effective Date.

Holders’ obligations under this Agreement are subject to the satisfaction, at or prior to the respective Closing, of the following conditions:

(a) Representations and Warranties True; Performance of Obligations. The representations and warranties made by the Company in Section 5 shall be true and correct in all material respects as of the Effective Date, and the Company shall have performed all obligations and conditions herein required to be performed or observed by it on or prior to such Closing.

(b) Consents, Permits, and Waivers. The Company shall have obtained any and all consents, permits and waivers necessary or appropriate for consummation of the transactions contemplated by the Transaction Agreements (except for such as may be properly obtained subsequent to the Closing).

(c) Corporate Documents. The Company shall have delivered to Holders or their counsel copies of all corporate documents of the Company as Holders shall reasonably request.

(d) Proceedings and Documents. All corporate and other proceedings in connection with the transactions contemplated at the Closing hereby and all documents and instruments incident to such transactions shall be reasonably satisfactory in substance and form to the Holders and their counsel, and the Holders and their counsel shall have received all such counterpart originals or certified or other copies of such documents as they may reasonably request.

(e) Payment of Fees. All fees required to be paid at the Closing under Section 9.1 shall have been paid.

(f) Compliance Certificate. The Company will have delivered to counsel for each Holder a certificate, executed on the Company’s behalf by the Company’s Chief Executive Officer, in substantially the form attached as Exhibit D, certifying the satisfaction of the closing conditions listed in this Section 7.1.

(g) Legal Opinion. The Holders will have received from the Company’s legal counsel a legal opinion, dated as of the Effective Date, in substantially the form attached as Exhibit E.

(h) Secretary’s Certificate. The Company will have delivered to counsel for each Holder a certificate, executed on the Company’s behalf by the Company’s Secretary, in substantially the form attached as Exhibit F.

The Company’s obligations under this Agreement are subject to the satisfaction, on or prior to the respective Closing, of the following conditions:

(a) Representations and Warranties True; Performance of Obligations. The representations and warranties made by Holders in Section 6 shall be true and correct in all material respects as of the Effective Date, and the Holders shall have performed and complied with all agreements and conditions herein required to be performed or complied with by Holders.

The Company agrees to prepare and file with the Commission, no later than fifteen (15) days following the date on which the Company’s Annual Report on Form 10-KSB is due for the fiscal year ending April 30, 2007 (the “Filing Date”), a registration statement on Form SB-2, Form S-3 or such other form of registration statement as may be required by the Securities Act or as may be deemed appropriate by the Company (the “Registration Statement”) to enable the resale of the Warrant Shares underlying the Closing Warrants (the “Registrable Securities”) by the Holders from time to time on the OTC Bulletin Board or in privately-negotiated transactions. The term “Registrable Securities” does not include the Warrant Shares underlying the Initial Interest Warrants or any Quarterly Interest Warrants issued to the Holders.

The Company will keep each Holder advised in writing as to the status of the Registration Statement as set forth herein. At the Company’s expense, the Company will:

(a) use commercially reasonable efforts to cause the Registration Statement to be declared effective by the Commission within forty-five (45) days of the Filing Date (in the case of no review of the Registration Statement by the Commission) or ninety (90) days of the Filing Date (in the case of a review of the Registration Statement by the Commission) (as applicable, the “Required Effective Date”);

(b) promptly and without delay prepare and file with the Commission, and concurrently provide copies to the Holder, such amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Registration Statement current, effective and free from any material misstatement or omission to state a material fact for a period not exceeding, with respect to each Holder’s Registrable Securities, the earlier of the (i) second anniversary of the effective date of the Registration Statement, (ii) the date on which the Holder may sell all Registrable Securities then held by the Holder without restriction by the volume limitations of Rule 144(e) of the Securities Act, or (iii) such time as all Registrable Securities have been sold pursuant to a Registration Statement;

(c) furnish such number of prospectuses and other documents incident to such prospectus, including any prospectus amendment or prospectus supplement, as a Holder from time to time may reasonably request;

(d) use commercially reasonable efforts to register and qualify the Registrable Securities under such other securities or blue sky laws of such jurisdictions as will be reasonably requested by the Holders; provided, that the Company will not be required, in connection with any such registration and qualification or as a condition to any such registration and qualification, to qualify to do business or to file a general consent to service of process in any such states or jurisdictions;

(e) notify each Holder of Registrable Securities covered by such Registration Statement at any time when a prospectus relating to such Registration Statement is required to be delivered under the Securities Act of the occurrence of any event as a result of which the prospectus included in such Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing;

(f) notify each Holder, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding for that purpose and promptly use its best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued;

(g) at the request of any such Holder, furnish: (i) at the sole expense of the Company, an opinion dated as of the effective date of the Registration Statement the counsel representing the Company for the purposes of such registration, addressed to the underwriters, if any, and to the Holder or Holders making such request, covering such matters as such underwriters and Holder or Holders may reasonably request; and (ii) letters dated as of the effective date of the Registration Statement and as of the closing date, from the independent certified public accountants of the Company, addressed to the underwriters, if any, and to the Holder or Holders making such request, covering such matters as such underwriters and Holder or Holders may reasonably request;

(h) if requested by the Holders, cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing the Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free, to the extent permitted by this Agreement, of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holders may request; and

(i) at any time after the Registrable Securities are covered by an effective Registration Statement, the Company may deliver to the Holders of such Registrable Securities a certificate (the “Suspension Certificate”) approved by the Chief Executive Officer of the Company and signed by an officer of the Company stating that the effectiveness of and sales of Registrable Securities under the Registration Statement would:

(A) materially interfere with any transaction that would require the Company to prepare financial statements under the Securities Act that the Company would otherwise not be required to prepare in order to comply with its obligations under the Exchange Act, or

(B) require public disclosure of any transaction of the type discussed in Section 8.2(i)(A) prior to the time such disclosure might otherwise be required;

Beginning five (5) Business Days after the receipt of a Suspension Certificate by Holders of Registrable Securities, the Company may, in its discretion, require such Holders of Registrable Securities to refrain from selling or otherwise transferring or disposing of any Registrable Securities or other Company securities then held by such Holders for a specified period of time that is customary under the circumstances (not to exceed 30 days during any 12-month period). The Company may impose stop transfer instructions to enforce any required agreement of the Holders under this Section 8.2(i).

Each Holder agrees that, upon receipt of a notice from the Company of the occurrence of any

event of the kind described in Section 8.2(e) or Section 8.2(f), such Holder will forthwith discontinue disposition of such Registrable Securities under the Registration Statement until such Holder’s receipt of the copies of the supplemented Prospectus and/or amended Registration Statement or until it is advised in writing (the “Advice”) by the Company that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement. The Company will use commercially reasonable efforts to ensure that the use of the Prospectus may be resumed as promptly as it practicable.

The Company acknowledges and agrees that the Holders will suffer material damages if the Registration Statement is not declared effective by the Commission by the Required Effective Date and maintained in the manner and within the time periods contemplated by Section 8.2 hereof, and it would not be feasible to ascertain the extent of such damages with precision. Accordingly, if the Registration Statement is not declared effective by the Commission on or prior to the Required Effective Date (the “Non-Registration Event”), then, for so long as the Non-Registration Event shall continue, the Company shall pay to each Holder as liquidated damages for each month during the pendency of such Non-Registration Event an amount equal to one (1%) percent per month (pro rated for any portion thereof) of the aggregate value of the Warrant Shares underlying the Holder’s Closing Warrants then held by such Holder (which shall be measured at $4.00 per share); provided, however, that no amount in liquidated damages shall be paid to any Holder pursuant to this Section 8.4 for the Company’s failure to register the Warrant Shares if such failure is as a result of an interpretation by the Commission that Securities Act Rule 415 prohibits such registration. Payments to be made pursuant to this Section 8.4 shall be due and payable to the Holders in immediately available funds within ten (10) business days after receipt of written demand from a Holder.

The Company will be responsible for all expenses incurred by it in connection with the preparation and filing of the Registration Statement, regardless of whether any Registrable Securities are sold pursuant to such Registration Statement. All selling expenses incurred by any Holder in connection with the Registration Statement or the Registrable Securities, including broker or similar commissions, will be borne by such Holder.

(a) Indemnification by Company. The Company will indemnify each Holder, and each Holder’s officers, directors, members, governors, employees, partners, legal counsel, and accountants, and each person controlling such Holder within the meaning of Section 15 of the Securities Act with respect to any registration, qualification, or compliance effected pursuant to this Section 8, and each underwriter, if any, and each person who controls, within the meaning of Section 15 of the Securities Act, any underwriter, against all expenses, claims, losses, damages, and liabilities (or actions, proceedings, or settlements in respect of such expenses, claims, losses, damages, and liabilities) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular, or other document (including any related registration statement, notification, or similar document) incident to any such registration, qualification, or compliance, or based on any omission (or alleged omission) to state in such document a material fact required to be stated in such document or necessary to make the statements in such document not misleading, or any violation by the Company of the Securities Act and any applicable state securities laws or any rule or regulation under the Securities Act or state securities laws applicable to the Company and relating to action or inaction

required of the Company in connection with any such registration, qualification, or compliance, and will reimburse each such Holder, and each of such Holder’s officers, directors, partners, legal counsel, and accountants, and each person controlling such Holder, and each such underwriter, and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating and defending or settling any such claim, loss, damage, liability, or action; provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability, or expense arises out of or is based on any untrue statement or omission based upon written information furnished to the Company by such Holder or underwriter and stated to be specifically for use in such document. The Parties expressly agree and acknowledge that the indemnity agreement contained in this Section 8.6(a) will not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the Company’s consent (which consent will not be unreasonably withheld, delayed or conditioned).

(b) Indemnification by Holder. Each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration, qualification, or compliance is being effected, indemnify the Company, and each of the Company’s directors, officers, legal counsel, and accountants, and each underwriter, if any, of the Company’s securities covered by such a registration statement, and each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, and each other such Holder, and each of their respective officers, directors, and partners, and each person controlling such Holder or other Company stockholder, against all claims, losses, damages, and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular, or other document, or any omission (or alleged omission) to state in such document a material fact required to be stated in such document or necessary to make the statements in such document not misleading, and will reimburse the Company, and such Holders, and directors, officers, legal counsel, and accountants, and underwriters, and control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability, or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular, or other document in reliance upon and in conformity with written information furnished to the Company by such Holder and stated to be specifically for use in such document; provided that such Holder’s obligations under this Section 8.6(b) will not apply to amounts paid in settlement of any such claims, losses, damages, or liabilities (or actions in respect of such claims, losses, damages, or liabilities) if such settlement is effected without such Holder’s consent (which consent will not be unreasonably withheld, delayed or conditioned); and provided further that in no event will any indemnity under this Section 8.6(b) exceed the net proceeds. For purposes of this Section 8.6(b) and Section 8.6(d), the term “net proceeds,” with respect to any particular Holder, means the proceeds from the offering received by such Holder after deducting underwriters’ commissions, discounts, and expenses attributable to the Registrable Securities sold by such Holder.

(c) Indemnification Procedures. Each party entitled to indemnification under this Section 8.6 (the “Indemnified Party”) will give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and will permit the Indemnifying Party to assume the defense of such claim or any litigation resulting from such claim; provided that counsel for the Indemnifying Party who will conduct the defense of such claim or any litigation resulting from such claim, will be approved by the Indemnified Party (whose approval will not be unreasonably withheld), and the Indemnified Party may participate in such defense at such Indemnified Party’s expense. Notwithstanding the foregoing, any Indemnified Party’s failure to give notice as provided in this Section 8.6(c) will not relieve the Indemnifying Party of the Indemnifying Party’s obligations under this Section 8.6 to the extent such failure is not prejudicial. No Indemnifying Party, in the defense of any such claim or litigation, will,

except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term of such judgment or such settlement the claimant’s or plaintiff’s release of such Indemnified Party from all liability in respect to such claim or litigation. Each Indemnified Party will furnish such information regarding such Indemnified Party or the claim in question as an Indemnifying Party may reasonably request in writing and as will be reasonably required in connection with defense of such claim and litigation resulting from such claim.

(d) Indemnification Unavailability. If the indemnification provided for in this Section 8.6 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage, or expense referred to in this Section 8.6, then the Indemnifying Party, instead of indemnifying such Indemnified Party under Section 8.6(a) or Section 8.6(b), will contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party, on the one hand, and of the Indemnified Party, on the other hand, in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations; provided, however, that in no event will any contribution by a Holder under this Section 8.6(d) exceed the net proceeds (as defined in Section 8.6(b)). The relative fault of the Indemnifying Party and of the Indemnified Party will be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the Parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission.

Each Holder will furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing and as will be reasonably required in connection with any registration, qualification, or compliance referred to in this Section 8.

With a view to making available the benefits of certain Commission rules and regulations that may permit the sale of the Warrant Shares underlying the Initial Interest Warrant and the Quarterly Interest Warrant, if exercised (the “Restricted Securities”), to the public without registration, the Company agrees to:

(a) file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and

(b) so long as a Holder owns any Restricted Securities, furnish to the Holder, promptly upon the Holder’s written request, a written statement by the Company as to the Company’s compliance with the reporting requirements of Rule 144 and the Exchange Act.

The Company shall pay to the Whitebox Entities all reasonable expenses, including the fees of its legal counsel, incurred by the Whitebox Entities and their advisor, Whitebox Advisors, LLC, in

connection with entry into this Agreement and the other Transaction Agreements including but not limited to any and all fees and expenses related to due diligence or other matters relating to or arising out of any of the foregoing.

This Agreement shall be governed by the laws of the State of Minnesota without regard to the conflicts of law principles of any jurisdiction. With respect to any disputes arising out of or related to this Agreement or to any other Transaction Agreement, the parties consent to the exclusive jurisdiction of, and venue in, the state courts in Hennepin County, Minnesota (or, in the event of exclusive federal jurisdiction, the federal courts of the District of Minnesota).

The representations, warranties, covenants and agreements made herein shall survive the closing of the transactions contemplated hereby. All statements as to factual matters contained in any certificate or other instrument delivered by or on behalf of the Company pursuant hereto in connection with the transactions contemplated hereby shall be deemed to be representations and warranties by the Company hereunder solely as of the date of such certificate or instrument.

This Agreement, and any and all rights, duties, and obligations under this Agreement, will not be assigned, transferred, delegated, or sublicensed by any party without the other party’s prior written consent. Any attempt by any party without such prior written consent to assign, transfer, delegate, or sublicense any rights, duties, or obligations that arise under this Agreement will be void. Subject to the foregoing and except as otherwise provided in this Agreement, the provisions of this Agreement will inure to the benefit of, and be binding upon, the parties’ respective successors, assigns, heirs, executors, and administrators.

The Transaction Agreements and all the other documents delivered pursuant hereto constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof and thereof, and no party shall be liable or bound to any other in any manner by any representations, warranties, covenants and agreements except as specifically set forth herein and therein.

In case any provision of this Agreement shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

This Agreement may be amended or modified only upon the written consent of the Company and the Holders holding a majority-in-interest of the Principal Amount of the Notes.

It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under any of the Transaction Agreements shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring. It is further agreed that any waiver, permit, consent or approval of any kind or character on any Holder’s part of any breach, default or noncompliance under any of the Transaction Agreements or any waiver on such party’s part of any provisions or conditions of any of the Transaction Agreements must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies under the Transaction Agreements or as otherwise afforded to any party shall be cumulative and not alternative.

All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (i) upon personal delivery to the party to be notified; (ii) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient, if not, then on the next business day; (iii) three (3) business days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (iv) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent to the Company at its address on the first page hereof and to the Holders at their respective addresses set forth on the signature page hereof or at such other address as the Company or an Holder may designate by ten (10) days advance written notice to the other parties hereto.

The titles of the sections and subsections of this Agreement are for convenience of reference only and are not to be considered in construing this Agreement. This Agreement may be delivered via facsimile and may be executed in any number of counterparts, each of which shall be an original, but all of which together shall constitute one instrument.

Each Holder acknowledges that it is not relying upon any representation or warranty of any person, firm, or corporation, other than the Company, in making its investment or decision to invest in the Company. Each Holder agrees that none of the other Holders or the respective controlling persons, officers, directors, partners, agents, or employees of any other Holder shall be liable for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the transactions contemplated hereby.

IN WITNESS WHEREOF, the undersigned have hereunto affixed their signatures.

SECURED PROMISSORY NOTE

$			April 20, 2007
			*2007 Secured Notes Series*

FOR VALUE RECEIVED, the undersigned, MedicalCV, Inc., a Minnesota corporation (the “Borrower”), with its principal executive office at ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, hereby promises to pay to the order of (the “Holder”), or its assigns, the principal sum of $ , or such greater or lesser amount as shall then equal the outstanding principal amount hereof (the “Principal Amount”), together with interest from the date of this Secured Promissory Note (this “Note”) on the outstanding principal balance at an annual rate equal to 11% per annum. All payments of principal and interest shall be made in immediately available funds in lawful money of the United States.

This Note is one of multiple notes in the 2007 Secured Notes Series (collectively, the “Notes”) referred to in that certain Secured Note Purchase Agreement dated April 20, 2007 by and among the Company, the Holder and certain other holders (the “Note Purchase Agreement”). The Notes are secured by a first priority security interest in and to the Company’s assets, as set forth in that certain Security Agreement April 20, 2007 by and among the Company, the Holder and certain other holders (the “Security Agreement”). Capitalized terms not otherwise defined in this Note have the meanings placed on them in the Note Purchase Agreement and/or the Security Agreement.

1. Payment of Principal and Interest

(a) The entire unpaid principal balance, together with any accrued but unpaid interest and other unpaid charges or fees hereunder, shall be due and payable on the date that is thirty-six (36) months following the Effective Date of the Note Purchase Agreement (the “Maturity Date”).

(b) During the initial twelve (12) month period following the Effective Date, interest on the Note will accrue and be added to the Principal Amount of the Note. Within thirty (30) days following the end of such 12-month period, the Company shall issue to the Holder a five-year Warrant, in substantially the form attached to the Note Purchase Agreement as Exhibit B2, which shall entitle the Holder to purchase such number of shares of the Company’s Common Stock that is equal to the quotient obtained by dividing (i) 60% of the accrued interest for the initial 12-month period by (ii) $4.00.

(c) Following the initial 12-month period, the Company will have the right to (i) pay the accrued interest on the Note quarterly in arrears or (ii) allow the interest for such quarter continue to accrue and be added to the Principal Amount of the Note. Any payment of accrued interest must be made to the Holder on or before the 15th day following the end of such quarter. If the Company elects to have the quarterly interest added to the Principal Amount of the Note, then the Company shall issue to the Holder, within thirty (30) days following the end of such quarter, a five-year Warrant, in substantially the

form attached to the Note Purchase Agreement as Exhibit B2, entitling the Holder to purchase such number of shares of the Company’s Common Stock that is equal to the quotient obtained by dividing (i) 60% of the accrued interest for the quarter by (ii) $4.00.

(d) The Borrower shall have the right to prepay this Note, in part or in whole, at any time during the term of this Note, subject to a premium payment (the “Premium Payment”) payable to the Holder as follows:

(i) 8% of the Principal Amount if prepayment is made within the first 12-month period following the Effective Date;

(ii) 6% of the Principal Amount if prepayment is made within the second 12-month period following the Effective Date; and

(iii) 3% of the Principal Amount if prepayment is made within the third 12-month period following the Effective Date.

The Prepayment Premium shall be paid to the Holder in immediately available funds simultaneously with the Prepayment. If the Borrower elects to prepay less than the whole Principal Amount then outstanding, then the Prepayment Premium shall apply only to such portion of the Principal Amount that is being prepaid at that time. The Prepayment Premium shall not apply if the prepayment of the Note is a result of a change of control of the Company.

(e) Notwithstanding anything herein to the contrary, if any payment of Principal Amount or interest (or, pursuant to Section 1(b) or (c) above, a Warrant issuance) becomes due on a Saturday, a Sunday or a day on which banks in the State of Minnesota are authorized or required by law to close, the due date thereof shall be extended to the immediately succeeding day which is not a Saturday, a Sunday or a day on which the banks in the State of Minnesota are closed, and any applicable interest thereon shall accrue during the period of such extension at the rate provided for herein.

(f) If the Principal Amount of the Note is prepaid in full prior to the Maturity Date, the Company agrees to issue to the Holder, at the time of the Prepayment, the Warrant that would otherwise have been issuable pursuant to Section 1(b) or 1(c) for such period, as applicable, calculated on a pro rata basis for that period.

2. Warrant Rights. The Holder shall be entitled to receive Warrants to purchase shares of the Borrower’s common stock, as set forth in the Note Purchase Agreement and in Sections 1(b) and 1(c) of this Note (without duplication).

3. Rights of Holder. Upon an Event of Default, the rights and remedies of the Holder are as set forth in the Note Purchase Agreement and the Security Agreement, which, among other things, provide that the with respect to any action taken in connection with the Note Purchase Agreement or the Security Agreement, the Holders of the 2007 Secured Note Series shall act in accordance with and under the directions of the Holders holding a majority-in-interest of the outstanding Principal Amount of the Notes, or a designee appointed by such Holders.

4. Security. This Note and the payment of all principal, interest and other sums hereunder is secured by a security interest in the Collateral, pursuant to the Note Purchase Agreement and the Security Agreement.

5. Amendments. Changes in or additions to this Note may be made, or compliance with any term, covenant, agreement, condition or provision set forth herein may be omitted or waived (either generally or in a particular instance and either retroactively or prospectively), only in writing.

6. Waiver. The failure of the Holder to insist, in any one or more instances, on performance of any of the terms, covenants and conditions hereof shall not be construed as a waiver or relinquishment of any rights granted hereunder or of the future performance of any such terms, covenants or conditions, but the obligation of the Borrower with respect thereto shall continue to be in full force and effect.

7. Benefits; Assignment. The rights and benefits of the Holder hereunder shall inure to the benefit of its successors and assigns, and Borrower acknowledges that Holder may pledge this Note to its Holders. The Borrower may not assign any rights or obligations hereunder without the prior written consent of the Holder, and any such attempted assignment shall be null and void and of no force or effect.

8. Notices. All notices, requests and demands to or upon the parties hereto shall be deemed to have been given or made when deposited in the mail, certified or registered, postage prepaid, addressed to the address of the party set forth in the Note Purchase Agreement or such other address as any party may request by notice given as aforesaid.

9. Collection. The Borrower agrees to pay any costs and expenses (including reasonable attorneys’ fees and disbursements) incurred by the Holder in the collection of any and all amounts due under this Note that are not paid when due and in the enforcement of the Holder’s rights under this Note.

10. Governing Law. This Note 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, without giving effect to the principles of conflict of laws thereof.

11. Severability. The holding of any provision of this Note to be invalid or unenforceable by a court of competent jurisdiction shall not affect any other provision hereof and all other provisions hereof shall remain in full force and effect.

IN WITNESS WHEREOF, this Secured Promissory Note has been executed and delivered on the date first above written by the undersigned Borrower.

(based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time); (b) if the OTC Bulletin Board is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the OTC Bulletin Board; (c) if the Common Stock is not then quoted for trading on the OTC Bulletin Board and if prices for the Common Stock are then reported in the “Pink Sheets” published by Pink Sheets, LLC (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported; or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the investors who are signatories to the Transaction Documents and reasonably acceptable to the Company.

Section 2. Exercise.

a) Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company of a duly executed facsimile or “.pdf” copy of the Notice of Exercise Form annexed hereto (or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of such Holder appearing on the books of the Company); and, within 3 Trading Days of the date said Notice of Exercise is delivered to the Company, the Company shall have received payment of the aggregate Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn on a United States bank, unless this Warrant is being exercised pursuant to the cashless exercise

provision set forth in Section 2(c) below. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within 3 Trading Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. In the event of any dispute or discrepancy, the records of the Company shall be controlling and determinative in the absence of manifest error. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

b) Exercise Price. The exercise price per share of the Common Stock under this Warrant shall be $4.00, subject to adjustment hereunder (the “Exercise Price”).

c) Cashless Exercise. If a Notice of Exercise Form is delivered at a time when (i) a registration statement permitting the Holder to resell the Warrant Shares is required to be effective but is not then effective, or (ii) the prospectus forming a part thereof is not then available to the Holder for the resale of the Warrant Shares, then this Warrant may also be exercised at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a certificate for the number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) = the VWAP on the Trading Day immediately preceding the date of such election;

(B) = the Exercise Price of this Warrant, as adjusted; and

(X) = the number of Warrant Shares issuable upon exercise of this Warrant in accordance with the terms of this Warrant by means of a cash exercise rather than a cashless exercise.

d) Mechanics of Exercise.

i. Authorization of Warrant Shares. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

ii. Delivery of Certificates Upon Exercise. Certificates for shares purchased hereunder shall be transmitted by the transfer agent of the Company to the Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company through its Deposit Withdrawal Agent Commission (“DWAC”) system if the Company is a participant in such system, and otherwise by physical delivery to the address specified by the Holder in the Notice of Exercise within 3 Trading Days from the delivery to the Company of the Notice of Exercise Form, surrender of this Warrant (if required) and payment of the aggregate Exercise Price as set forth above (“Warrant Share Delivery Date”). This Warrant shall be deemed to have been exercised on the date (a) the Exercise Price is received by the Company or (b) notification to the Company that this Warrant is being exercised pursuant to a cashless exercise provision set forth in Section 2(c) above. The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised by payment to the Company of the Exercise Price (or by cashless exercise, if permitted) and all taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of such shares, have been paid.

iii. Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver to Holder a new Warrant evidencing the rights of Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

iv. Rescission Rights. If the Company fails to cause its transfer agent to transmit to the Holder a certificate or certificates representing the Warrant Shares pursuant to this Section 2(d) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.

v. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which Holder would otherwise be entitled to purchase upon such exercise, the Company shall at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

vi. Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event certificates for Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached

hereto duly executed by the Holder; and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto.

vii. Closing of Books. The Company will not close its shareholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

Section 3. Certain Adjustments.

a) Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (A) pays a stock dividend or otherwise make a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant, any other warrant or any option), (B) subdivides outstanding shares of Common Stock into a larger number of shares, (C) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (D) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

b) Adjustment for Issuance of Shares of Common Stock Below Exercise Price. From the date hereof until 12 months after the Closing Date (the “Adjustment Period”), the Exercise Price shall be subject to adjustment from time to time as provided in this Section 3(b).

i. If during the Adjustment Period, the Company issues or sells, or in accordance with this Section 3(b) is deemed to have issued or sold, any shares of Common Stock (excluding Excluded Securities) for a consideration per share (the “New Securities Issuance Price”) less than a price (the “Applicable Price”) equal to the Exercise Price in effect immediately prior to such time, then immediately after such issue or sale, the Exercise Price then in effect shall be reduced to an amount equal to the New Securities Issuance Price.

ii. For purposes of determining the adjusted Exercise Price under Section 3(b) hereof, the following will be applicable:

conversion, exchange or exercise of any Convertible Securities issuable upon exercise of such Option is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 3(b)(ii)(A), the “lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exchange or exercise of any Convertible Securities issuable upon exercise of such Option” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon granting or sale of the Option, upon exercise of the Option and upon conversion, exchange or exercise of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Exercise Price shall be made upon the actual issuance of such Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Stock upon conversion, exchange or exercise of such Convertible Securities. “Convertible Securities” means any evidence of indebtedness, shares or securities, in each case convertible into or exchangable for Common Stock. “Options” means rights, options or warrants to subscribe for, purchase or otherwise acquire shares of Common Stock or Convertible Securities.

(B) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon such conversion, exchange or exercise thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 3(b)(ii)(B), the “lowest price per share for which one share of Common Stock is issuable upon such conversion, exchange or exercise” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the issuance or sale of the Convertible Security and upon the conversion, exchange or exercise of such Convertible Security. No further adjustment of the Exercise Price shall be made upon the actual issuance of such Common Stock upon conversion, exchange or exercise of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Exercise Price had been or are to be made pursuant to other provisions of this Section 3(b)(ii), no further adjustment of the Exercise Price shall be made by reason of such issue or sale.

Securities provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 3(b)(ii)(C), if the terms of any Option or Convertible Security that was outstanding as of the Closing Date are changed in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such change. No adjustment shall be made if such adjustment would result in an increase of the Exercise Price then in effect. Notwithstanding the foregoing, no adjustment shall be made to the Exercise Price of this Warrant due to anti-dilution adjustments made to securities outstanding as of the Closing Date as a result of the issuance of Securities pursuant to the Transaction Documents.

(D) Calculation of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a consideration of $0.01. If any Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the gross amount received by the Company therefor. If any Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except where such consideration consists of marketable securities, in which case the amount of consideration received by the Company will be the arithmetic average of the closing sale prices of such securities during the ten (10) consecutive trading days ending on the date of receipt of such securities. The fair value of any consideration other than cash or securities will be determined jointly by the Company and the holders of at least a majority in interest of the Warrants then outstanding.

the date of the Purchase Agreement, provided that such securities have not been amended since the date of the Purchase Agreement (other than on a non-discretionary basis pursuant to the pre-existing anti-dilution provisions thereof) to increase the number of such securities or to decrease the exercise, exchange or conversion price of any such securities, (c) securities issued pursuant to acquisitions or strategic transactions approved by a majority of the disinterested directors, provided any such issuance shall only be to a Person which is, itself or through its subsidiaries, an operating company in a business synergistic with the business of the Company and in which the Company receives benefits in addition to the investment of funds, but shall not include a transaction in which the Company is issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities, (d) shares of Common Stock or other securities issued in connection with any stock split, stock dividend or recapitalization of the Company (subject to Section 3(a) hereof), and (e) shares of Common Stock or other securities issued in connection with any registered primary public offering.

c) Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

d) Voluntary Adjustment By Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

e) Notice to Holders.

i. Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly mail to each Holder a notice setting forth the Exercise Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. The Holder is entitled to exercise this Warrant during the 20-day period commencing on the date of such notice to the effective date of the event triggering such notice.

Section 4. Transfer of Warrant.

a) Transferability. Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof, this Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. A Warrant, if properly assigned, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

b) New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice.

c) Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

d) Transfer Restrictions. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this Warrant shall not be registered pursuant to an effective registration statement under the Securities Act and under applicable state securities or blue sky laws, the Company may require, as a condition of allowing such transfer (i) that the Holder or transferee of this Warrant, as the case may be, furnish to the Company a written opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that such transfer may be made without registration under the Securities Act and under applicable state securities or blue sky laws, (ii) that the Holder or transferee execute and deliver to the Company an investment letter in form and substance acceptable to the Company and (iii) that the transferee be an “accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7), or (a)(8) promulgated under the Securities Act or a “qualified institutional buyer” as defined in Rule 144A(a) under the Securities Act.

Section 5. Miscellaneous.

a) No Rights as Shareholder Until Exercise. This Warrant does not entitle the Holder to any voting rights or other rights as a shareholder of the Company prior to the exercise hereof as set forth in Section 2(d)(ii).

b) Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

c) Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business Day.

d) Authorized Shares.

The Company covenants that during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or

of any requirements of the Trading Market upon which the Common Stock may be listed.

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its articles of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, 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 actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (a) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (b) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant, and (c) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be necessary to enable the Company to perform its obligations under this Warrant.

Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

e) Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance with the provisions of the Purchase Agreement.

f) Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, will have restrictions upon resale imposed by state and federal securities laws.

g) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice the Company’s or the Holder’s rights, powers or remedies, notwithstanding the fact that all rights hereunder terminate on the Termination Date. If the Company or a Holder willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder or Company (as the case may be), the breaching party shall pay to the other party such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by the non-breaching party in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

h) Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in accordance with the notice provisions of the Purchase Agreement.

i) Limitation of Liability. No provision hereof, in the absence of any affirmative action by Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of Holder for the purchase price of any Common Stock or as a shareholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

j) Remedies. Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to seek specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

k) Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of all Holders from time to time of this Warrant and shall be enforceable by any such Holder or holder of Warrant Shares.

l) Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

m) Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

n) Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. In the event of any dispute or discrepancy, the records of the Company shall be controlling and determinative in the absence of manifest error. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

vii. Closing of Books. The Company will not close its shareholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

Section 3. Certain Adjustments.

the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

(A) Issuance of Rights or Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exchange or exercise of any Convertible Securities issuable upon exercise of such Option is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 3(b)(ii)(A), the “lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exchange or exercise of any Convertible Securities issuable upon exercise of such Option” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon granting or sale of the Option, upon exercise of the Option and upon conversion, exchange or exercise of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Exercise Price shall be made upon the actual issuance of such Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Stock upon conversion, exchange or exercise of such Convertible Securities. “Convertible Securities” means any evidence of indebtedness, shares or securities, in each case convertible into or exchangable for Common Stock. “Options” means rights, options or

warrants to subscribe for, purchase or otherwise acquire shares of Common Stock or Convertible Securities.

(C) Change in Option Price or Conversion Rate. If the purchase or exercise price provided for in any Options, or the additional consideration, if any, payable upon the issue, conversion, exchange or exercise of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exchangeable or exercisable for Common Stock changes at any time, the Exercise Price in effect at the time of such change shall be adjusted to the Exercise Price which would have been in effect at such time had such Options or Convertible Securities provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 3(b)(ii)(C), if the terms of any Option or Convertible Security that was outstanding as of the Closing Date are changed in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such change. No adjustment shall be made if such adjustment would result in an increase of the Exercise Price then in effect. Notwithstanding the foregoing, no adjustment shall be made to the Exercise Price of this Warrant due to anti-dilution adjustments made to securities outstanding as of the date hereof as a result of the issuance of Securities pursuant to the Transaction Documents.

Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the gross amount received by the Company therefor. If any Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except where such consideration consists of marketable securities, in which case the amount of consideration received by the Company will be the arithmetic average of the closing sale prices of such securities during the ten (10) consecutive trading days ending on the date of receipt of such securities. The fair value of any consideration other than cash or securities will be determined jointly by the Company and the holders of at least a majority in interest of the Warrants then outstanding.

(E) Exceptions to Adjustment of Exercise Price. Notwithstanding the foregoing, no adjustment will be made under this Section 3(b) in respect of Excluded Securities. “Excluded Securities” means the issuance of (a) shares of Common Stock or options to employees, officers or directors of, or consultants to, the Company pursuant to any stock option agreement, stock option plan or equity incentive plan duly adopted by a majority of the non-employee members of the Board of Directors of the Company or a majority of the members of a committee of non-employee directors established for such purpose (for purposes of clarity, the issuance of shares of Common Stock upon exercise of options granted pursuant to a stock option agreement, stock option plan or equity incentive plan subsequent to the date hereof shall also be Excluded Securities), (b) securities upon the exercise or exchange of or conversion of (i) any Securities issued in connection with the Purchase Agreement; (ii) securities to a registered broker-dealer in connection with the transactions contemplated by the Purchase Agreement; and/or (iii) other securities or rights exercisable or exchangeable for or convertible into shares of Common Stock which are issued and outstanding on the date of the Purchase Agreement, provided that such securities have not been amended since the date of the Purchase Agreement (other than on a non-discretionary basis pursuant to the pre-existing anti-dilution provisions thereof) to increase the number of such securities or to decrease the exercise, exchange or conversion price of any such securities, (c) securities issued pursuant to acquisitions or strategic transactions approved by a majority of the disinterested directors, provided any such issuance shall only be to a Person which is, itself or through its subsidiaries, an operating company in a business synergistic with the business of the Company and in which the Company receives benefits in addition to the investment of funds, but shall not include a transaction in which the Company is issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities, (d) shares of Common Stock or other securities issued in connection with any stock split, stock dividend or recapitalization of the Company (subject to Section 3(a) hereof), and (e) shares of Common Stock or other securities issued in connection with any registered primary public offering.

e) Notice to Holders.

ii. Notice to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common Stock; (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock; (C) the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights; (D) the approval of any shareholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, of any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property; (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company; then, in each case, the Company shall cause to be mailed to the Holder at its last address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. The Holder is entitled to exercise this Warrant during the 20-day period commencing on the date of such notice to the effective date of the event triggering such notice.

SECURITY AGREEMENT AND FORM OF UCC FINANCING STATEMENT

THIS SECURITY AGREEMENT (this “Agreement”) is entered into effective as of April 20, 2007 by MedicalCV, Inc., a Minnesota corporation having its principal offices at ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (the “Debtor”), in favor of the parties listed on Exhibit 1 attached hereto (the “Secured Parties”).

Pursuant to the Secured Note Purchase Agreement dated of even date herewith by and among the Debtor and the Secured Parties (the “Note Purchase Agreement”), and for good and valuable consideration, Debtor hereby agrees for the benefit of the Secured Parties as follows:

1. SECURITY INTEREST AND COLLATERAL

Debtor hereby grants the Secured Parties a first priority security interest in all of the Debtor’s right, title, and interest in and to the property described below (collectively referred to as the “Security Interest”) as a security for the payment and performance of certain Secured Promissory Notes issued pursuant to the Note Purchase Agreement by Debtor in favor of the Secured Parties, respectively (the “Notes”), together with accrued but unpaid interest thereon, and costs of collection, including reasonable attorneys’ fees, and all other obligations of Debtor to Secured Parties of any nature whatsoever (all known collectively as the “Obligations”). The Security Interest shall attach to all assets of the Debtor of every kind and every description, whether now owned or hereafter acquired, and all proceeds thereof (the “Collateral”), which shall include without limitation the following:

General Intangibles: All general intangibles of the Debtor, whether now owned or hereafter acquired, including without limitation all present and future patents and patent applications in all jurisdictions and territories (foreign and domestic), together with all divisions, reissues, reexaminations, term extensions, and continuations associated therewith, copyrights, trademarks, service marks, trade names, trade secrets, know-how, processes, and all licenses or agreements of any kind or nature pursuant to which the Debtor possesses, uses, or has authority to possess or use any of the foregoing, customer or supplier lists and contracts, manuals, operating instructions, permits, franchises, the right to use the Debtor’s name and the goodwill of the Debtor’s business.

Inventory: All inventory of the Debtor, as that term is defined in the Uniform Commercial Code, whether now owned or hereafter acquired or in which the Debtor obtains rights, whether consisting of whole goods, spare parts or components, supplies or materials whether acquired, held or furnished for sale, for lease or under contracts or for manufacture or processing, and wherever located;

Equipment: All equipment of the Debtor, whether now owned or hereafter acquired, including all present and future machinery, vehicles, furniture, fixtures, office and recordkeeping equipment, parts, tools, supplies and all other goods (except inventory) used or bought for use by the Debtor for any business or enterprise and including specifically (without limitation) all accessions thereto, all substitutions and replacements thereof, and all like or similar property now owned or hereafter acquired by the Debtor, and all of which is owned by the Debtor; and

of taxes or other liabilities, or any other transaction or event, whether such right to payment is created, generated or earned by the Debtor or by some other person who subsequently transfers his, her or its interest to the Debtor, whether such right to payment is or is not already earned by performance, and howsoever such right to payment may be evidenced, together with all other rights and interests (including all liens and other security interests) which the Debtor may at any time have by law or agreement against any account debtor or other person obligated to make such payment or against any property of such account debtor or other persons including, but not limited to, all present and future accounts, contract rights, chattel paper, bonds, notes and other debt instruments, and rights to payment in the nature of general intangibles.

The Collateral shall include (i) all substitutes and replacements for and proceeds of any and all of the foregoing property, and in the case of all tangible Collateral, all accessions, accessories, attachments, parts, equipment and repairs now or hereafter attached or affixed to or use in connection with any such goods and (ii) all warehouse receipts, bills of lading and other documents of title now or hereafter covering such goods.

2. REPRESENTATIONS, WARRANTIES AND COVENANTS

Debtor represents, warrants, and covenants that:

(a) Existence and Authority. Debtor is a corporation, duly organized, validly existing and in good standing under the laws of the State of Minnesota, having full power and authority to make and deliver this Agreement. The correct name of the Debtor is set forth at the beginning of this Agreement. Debtor’s principal place of business and president are located at the address as set forth in the opening paragraph of this Agreement. The Debtor covenants with the Secured Parties that it will not change its name, principal executive office, its mailing address, its registered agent or its type or jurisdiction of organization without providing each Secured Party ten days prior written notice.

(b) Title; Maintenance. Debtor is and will be, the owner of the Collateral, free of all liens, encumbrances and security interests except for the security interests created hereby or any interest specifically consented to in writing by the Secured Parties. The Debtor will keep the Collateral in good order and repair.

(c) Financing Statements. The Debtor authorizes the Secured Parties to file all financing statements, documents or records, and any amendments thereto, in such form as the Secured Parties deem necessary to perfect their Security Interest.

(e) No Encumbrances. The debtor will not pledge, lien or in any way encumber the Collateral without the prior written consent of the Secured Parties.

(f) Negative Covenants. Debtor will not at any time without the Secured Parties’ prior written consent (i) other than in the ordinary course of its business, sell, lease or otherwise dispose of or transfer any of the Collateral, (ii) merge or consolidate with another entity or (iii) change its state of organization or location.

(g) Inspections. Debtor grants the Secured Parties an irrevocable license to enter Debtor’s business location during normal business hours upon giving reasonable notice to Debtor to (i) account for and inspect all Collateral, (ii) verify Debtor’s compliance with this Agreement and (iii) examine and copy Debtor’s books and records relating to the Collateral.

3. DEFAULT, REMEDIES AND ACTIONS OF SECURED PARTIES

(a) Defaults. Debtor shall be in default under this Agreement upon the happening of any of the Events of Default as defined in the Note Purchase Agreement.

(b) Remedies. In the event of a default (i) the Secured Parties shall have the right, at their option and without demand or notice, to declare all or any part of the Obligations immediately due and payable (to the extent that the Obligations are not already by their terms immediately due and payable without any action on the part of the Secured Parties); (ii) the Secured Parties may exercise, in addition to the rights and remedies granted hereby, all of the rights and remedies of a secured party under the Uniform Commercial Code as adopted in Minnesota or under any other applicable law (the “UCC”); (iii) the Secured Parties may exercise their rights to possess, transfer and dispose of the Collateral; (iv) the Secured Parties may request, and Debtor will agree, to segregate and keep the Collateral in trust for the Secured Parties in good order and repair and will immediately deliver the Collateral at a place specified by the Secured Parties together with all related documents; and (v) Debtor agrees to pay all costs and expenses incurred by the Secured Parties in the collection of any of the Obligations or the enforcement of any of the Secured Parties’ rights.

(c) Sale of Collateral. Upon any default, Debtor agrees that ten (10) or more calendar days prior written notice is commercially reasonable notice of any public or private sale or transfer of Collateral by the Secured Parties. Upon any default, Debtor irrevocably grants the Secured Parties a license to enter upon Debtor’s premises without notice or judicial order to take possession of the Collateral. The Secured Parties are hereby granted a license or other right to use, without charge, all of the Debtor’s property, including, without limitation, all of the Debtor’s labels, trademarks, copyrights, patents and advertising matter or any property of a similar nature, as it pertains to the Collateral, in completing production of advertising for sale and selling any Collateral, and Debtor’s rights under all licenses shall inure to the Secured Parties’ benefit until the Obligations are paid in full.

(d) Power of Attorney. Debtor grants the Secured Parties an irrevocable Power of Attorney to (i) execute or endorse on Debtor’s behalf any checks, financing statements, instruments, certificates of title and statements of origin pertaining to the Collateral; (ii) supply any omitted information and correct errors in any documents between the Secured Parties and Debtor; (iii) initiate and settle any insurance claims pertaining to the Collateral; and (iv) do anything to preserve and protect the Collateral and the Secured Parties’ rights and interests therein.

(e) Costs and Expenses. The Debtor will pay or reimburse the Secured Parties on demand for all out-of-pocket expenses (including in each case all filing, recording fees, taxes and all reasonable fees and expenses of counsel and of any experts and agents) incurred by the Secured Parties in connection with the creation, perfection, protection, satisfaction or foreclosure of the Collateral and the preparation, administration, continuance, amendment or enforcement of this Agreement, and all such costs and expenses shall be part of the Obligations secured by the Collateral.

(f) Defense. The Debtor will at its own expense, and using its commercially reasonable efforts and sound business judgment, protect and defend the Collateral against all claims or demands of all persons other than the Secured Parties that would cause material harm to the Secured Parties.

(j) Waiver of Notice and Hearing. The Debtor hereby waives all rights to a judicial hearing of any kind prior to the exercise by the Secured Parties of their rights to possession of the

Collateral without judicial process or of their rights to replevin, attach or levy upon the Collateral without prior notice or hearing. In the event that a pre-judgment order for replevin is obtained, Debtor waives any requirement of the Secured Parties to post bond. DEBTOR HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

(k) Joint Action of the Secured Parties. With respect to any action taken in connection with this Agreement, the Secured Parties shall act in accordance with and under the directions of the Secured Parties holding a majority-in-interest of the outstanding Principal Amount of the Notes, or a designee appointed thereby. If the Secured Parties determine to act through a single Secured Party or other designee, the Secured Parties shall so inform the Debtor in writing. Action thereafter taken by such Secured Party or designee shall be deemed to be taken on behalf of all Secured Parties.

4. Miscellaneous.

(a) No Waiver; Cumulative Remedies. No failure delay on the part of the Secured Parties to exercise any right, power or remedy under this Agreement shall operate as a waiver thereof. In addition, no single or partial exercise of any right, power or remedy shall preclude any other or further exercise thereof or the exercise of any other right, power or remedy under this Agreement. The remedies provided for in this Agreement are cumulative and not exclusive of any remedies provided by law.

(b) Law Governing and Construction. The validity, construction and enforceability of this Agreement shall be governed by the laws of the State of Minnesota, without giving effect to conflict of laws principles thereof.

(c) Continuing Interest. This Agreement shall create a continuing security interest in the Collateral and shall remain in full force and effect until the satisfaction in full of all of the Obligations. At such time as Debtor shall completely satisfy all of the Obligations, this Agreement shall terminate and the Secured Parties shall execute and deliver to Debtor all instruments as may be necessary to re-vest in Debtor full title to the Collateral or evidence such termination.

(d) Severability. The provisions of this Agreement are severable. If any clause or provision is held invalid and unenforceable in whole or in part in any jurisdiction, then such invalidity or unenforceability shall affect only such clause or provision, or part thereof, in such jurisdiction, and shall not in any manner affect such clause or provision in any other jurisdiction, or any other clause or provision of this Agreement in any jurisdiction.

(e) Modifications. Any modifications or termination of this Agreement may be made only by a writing signed by all of the parties.

LEGAL OPINION

April 20, 2007

To: Holder under the Secured Note Purchase Agreement dated April 20, 2007

Ladies and Gentlemen:

We have acted as counsel to MedicalCV, Inc., a Minnesota corporation (the “Company”) in connection with a Secured Note Purchase Agreement (the “SNPA”) dated as of April 20, 2007 between the Company and an affiliate of Whitebox Advisors, LLC (“Whitebox”). This opinion letter is delivered to you at the Company’s request under Section 7.1(g) of the SNPA. All capitalized terms used, and not otherwise defined, in this opinion letter have the meanings given to them in the SNPA.

In connection with this opinion, we have reviewed drafts of the following documents (collectively, the “Transaction Agreements”), each of which is dated as of April 20, 2007, unless otherwise described:

1. the Secured Note Purchase Agreement;

2. the Secured Promissory Note;

3. the Security Agreement; and

4. the Closing Warrant.

For purposes of this opinion letter we have reviewed such documents and made such other investigation as we have deemed appropriate. As to certain matters of fact material to the opinions expressed in this letter, we have relied on the representations made in the Transaction Agreements and certificates of officers of the Company. We have not independently established the facts so relied on.

As used in this opinion letter, the term “Collateral” has the meaning given in the Security Agreement. References in this opinion letter to the “UCC” mean the Uniform Commercial Code as in effect in the State of Minnesota on the date hereof. As used in this opinion letter, the phrases “to our knowledge,” “known to us” or similar words mean the actual, conscious awareness on the date of this letter of ▇▇▇▇▇▇ and ▇▇▇▇▇▇, Professional Association, the lawyers in our firm who have been actively involved in the negotiation or preparation of the Transaction Agreements or this letter.

We assume with your permission and without investigation: (i) the due authorization, execution and delivery of the Transaction Agreements by all parties thereto other than the Company, (ii) the validity, binding effect and enforceability under applicable law of the Transaction Agreements against the parties thereto other than the Company, (iii) the authenticity of all documents submitted to us as originals, (iv) the genuineness of all signatures; (v) the legal capacity of natural persons, (vi) the conformity to originals of all documents submitted to us as copies and the authenticity of the originals of such copies, and (vii) that Whitebox has given value and the Company has rights in the Collateral, in each case within the meaning of Section 9 of the UCC, and (viii) that the description of the Collateral reasonably identifies what is described, within the meaning of Section 9 of the UCC.

Based upon the assumptions set forth above and the other limitations and qualifications set forth below, we are of the opinion that:

1. The Company is duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Minnesota.

2. The Company has corporate power and authority to conduct its business as described in the Company’s SEC Filings and to enter into and perform its obligations under the Transaction Agreements.

3. The Company is duly qualified to transact business and is in good standing in any jurisdiction in which it owns or leases substantial property or in which the conduct of its business requires such qualification, except where the failure to do so would not, individually or in the aggregate, have a material adverse effect on the properties, assets, operations, business or condition (financial or otherwise) of the Company.

4. To our knowledge, all of the outstanding shares of the Company’s capital stock have been duly authorized and validly issued, are fully paid and nonassessable and have been issued in compliance with the registration and qualification requirements of federal and state securities laws or were issued pursuant to an available exemption from the registration and qualification requirements of applicable federal and state securities laws.

5. Pursuant to a Securities Purchase Agreement dated October 13, 2006, Potomac Capital Partners LP, Potomac Capital International Ltd. and Pleiades Investment Partners-R LP were granted participation rights in future financings of the Company, which participation rights have been validly waived by said parties in connection with the transaction contemplated by the Transaction Agreements. Otherwise, to our knowledge, no stockholder of the Company or any other person has any preemptive right, right of first refusal or other similar right to subscribe for or purchase the Company’s securities arising (a) by operation of the Articles of Incorporation or Bylaws of the Company or the Minnesota Business Corporation Act or (b) otherwise.

6. The Transaction Agreements have been duly authorized, executed and delivered by, and are valid and binding agreements of, the Company, enforceable in accordance with their terms, except as rights to indemnification thereunder may be limited by applicable law and except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting creditors’ rights generally or by general equitable principles.

7. The Notes, Warrants and Warrant Shares have been duly authorized for issuance and sale pursuant to the Transaction Agreements and, when issued and delivered by the Company pursuant to payment of the consideration set forth in the Transaction Agreements, will be validly issued, fully paid and nonassessable.

8. The provisions of the Security Agreement are sufficient to create in favor of Whitebox the security interest, as described therein, in all right, title and interest of the Company in those items and types of Collateral described in the Security Agreement in which a security interest may be created under Section 9 of the UCC. The filing of a UCC-1 financing statement (within the meaning of Section 9-502(a) of the UCC) with the Office of the Secretary of the State of Minnesota is sufficient to perfect a security interest in the Collateral, to the extent that a security interest may be perfected by filing a financial statement under the UCC in such office.

9. No governmental approvals or filings are required for the execution and delivery of the Transaction Agreements on behalf of the Company, the payment of the Company’s obligations under the Transaction Agreements, or the creation by the Company of the security interests created by the Transaction Agreements, except for the filings necessary to perfect the liens granted under the Transaction Agreements.

10.
