BioDrain Medical, Inc.

MEDICAL ADVISORY BOARD WARRANT AGREEMENT

          This Advisory Board Warrant Agreement is made and entered as of the 7th day of December, 2006 (the Agreement Date”) by and between BioDrain Medical, Inc., a Minnesota corporation (“Company”) and Medical Advisory Board member Karen A. Ventura (the “Warrantee”) as consideration for Board membership.

1. Warrant Grant. The Company hereby grants to the Warrantee a warrant (the “Warrant”) to purchase 5,000 shares (“Warrant Shares”, with each being a “Warrant Share”) of its $0.01 par value common stock (“Share”), under the terms and conditions set forth below.

2. Nonstatutory Option. The Warrant is granted to purchase up to the number of shares of authorized but unissued common stock of the Company specified in Section 1 (the “Shares”). The Warrant will expire, and all rights to exercise it will terminate on the earliest of: (a) the date provided below in Sections 8 and 9, and (b) the Expiration Date.

3. Exercise Price. The exercise price of each Warrant Share of the Company as of any exercise date is $1.00 per Share.

4. Period of Exercise. The Warrant will expire at 5:00 p.m. on the fifth anniversary of the Agreement Date (“the Expiration Date”).

5. Vesting of Options. Warrantee will have the right to exercise the Warrant in accordance with the following schedule:

          (a) The Shares subject to Warrant will vest in 90 days from the Agreement Date.

6. Transferability. The Warrant is not transferable except by will or the laws of descent and distribution and may be exercised during the lifetime of the Warrantee only by the Warrantee, and if exercised following the Warrantee’s death, by the Warrantee’s legal representative upon presenting evidence of authority to act on behalf of the Warrantee’s estate acceptable to the Company.

7. Change in Control. If the Company enters into a binding agreement during the time that Warrantee is a Medical Advisory Board member of the Company that results in a change in control (as defined in the following sentence), then 100% of the Shares will vest. For purposes of this Warrant Agreement, “change in control” means that:

          (a) any individual, partnership, firm, corporation, association, trust, unincorporated organization or other entity or person, or any syndicate or group deemed to be a person under Section 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is or becomes the “beneficial owner” (as defined in Rule 13d-3 of the General Rules and Regulations under the Exchange Act), directly or indirectly, of securities of the Corporation representing fifty percent (50%) or more of the combined voting power of the Company’s then outstanding securities entitled to vote in the election of directors of the Company; or

          (b) there occurs a reorganization, merger, consolidation or other corporate transaction involving the Company (“Transaction”), in each case, with respect to which the stockholders of the Company immediately prior to such Transaction do not, immediately after the Transaction, own more than fifty

1

percent (50%) of the combined voting power of the Company or other corporation resulting from such Transaction; or

          (c) all or substantially all of the assets of the Company are sold, liquidated or distributed.

8. Warrant Lapse. The Warrant will lapse and becomes unexercisable in full on the earliest of the following events:

          (a) three (3) months following the Warrantee’s death, as provided below in Section 9;

          (b) the date otherwise provided below in Section 9, unless the Board of Directors otherwise extends such period before the applicable expiration date.

9. Medical Advisory Board Resignation. If Warrantee ceases to be a Medical Advisory Board member for any reason other than that described in this Section 9, Warrantee will have the right, subject to the other provisions of this Agreement, to exercise the Warrant for up to ninety (90) days following the date of termination, but only to the extent that on the date of termination the Warrantee’s right to exercise such Warrant had vested, and at the end of such period the Warrant will expire, and all rights to exercise it will terminate.

          (a) If Warrantee dies while a Medical Advisory Board member, or after ceasing to be a Medical Advisory Board member but during the period while he or she could have exercised an Warrant under the preceding sub-Sections, the Warrant granted to the Warrantee may be exercised, to the extent it has vested at the time of death at any time within ninety (90) days after the Warrantee’s death, by the executors or administrators of his or her estate or by any person or persons who acquire the Warrant by will or the laws of descent and distribution, but not beyond the otherwise applicable term of the Warrant.

10. Adjustment in Capitalization. If there is any change in the outstanding common stock of the Company by reason of a stock dividend or split, recapitalization, reclassification, or other similar capital change, the aggregate number of Warrant Shares subject to the Warrant will be appropriately adjusted by the Company, as directed by the Board of Directors of the Company whose determination is final and conclusive, except that fractional Shares will be rounded to the nearest whole Share. In any such case, the number and kind of Shares that are subject to the Warrant and the Warrant exercise price per Share will be proportionately adjusted without any change in the aggregate Warrant price to be paid upon exercise of the Warrant.

11. Amendment, Modification and Termination of Agreement. The Board of Directors of the Company may at any time terminate, and from time to time may amend or modify Agreement; provided, however, that no amendment, modification, or termination of this Agreement may in any manner adversely affect the Warrant without the consent of the Warrantee.

12. Lock up Period. The Warrantee understands that the Company at a future date may file a registration or offering statement (the “Registration Statement”) with the Securities and Exchange Commission to facilitate an initial public offering of its securities. The Warrantee agrees, for the benefit of the Company, that should such an initial public offering be made and should the managing underwriter of such offering require, the Warrantee will not, without the prior written consent of the Company and such underwriter, during the Lock Up Period as defined herein: (i) sell, transfer or otherwise dispose of, or agree to sell, transfer or otherwise dispose of any Shares beneficially held by the Warrantee during the Lock Up Period; (ii) sell, transfer or otherwise dispose of, or agree to sell, transfer or otherwise dispose of any options, rights or warrants to purchase any Shares beneficially held by the Warrantee during the Lock Up Period; or (iii) sell or grant, or agree to sell or grant, options, rights or warrants with respect to any Shares. The foregoing does not prohibit gifts to donees or transfers by will or the laws of descent to heirs or beneficiaries provided that such donees, heirs and beneficiaries are bound by the restrictions set forth herein. The term “Lock Up Period” means the lesser of (a) 180 days or (b) the period during which Company officers and directors are restricted by the managing underwriter from effecting any sales or transfers of the Company’s common stock. The Lock Up Period will commence on the effective of the Registration Statement.

The foregoing notwithstanding, the Company has no obligation to register the Warrant or any Shares.

          (2) Investment Intent. Unless the Company has determined that the following representation is unnecessary, each person exercising any portion of the Warrant will be required, as a condition to the issuance of Shares pursuant to exercise of the Warrant, to make a representation in writing (a) that he or she is acquiring the Shares for his or her own account for investment and not with a view to, or for sale in connection with, the distribution of any part thereof, (b) that before any transfer in connection with the resale of the Shares, he or she will obtain the written opinion of counsel for the Company, or other counsel acceptable to the Company, that the Shares may be transferred.
