ESCROW AGREEMENT ("Escrow Agreement") dated as of July 3, 2008 by and among AMERICAN SCIENTIFIC RESOURCES, INC., a Nevada corporation ("Company") and The Tripod Group, LLC,  a Wisconsin limited liability company ("Purchaser"), and Robert C. Laskowski ("Escrow Agent").

WHEREAS, the Company is the beneficial and record owner of 18,000,000 shares of the Company's common stock (the “Escrow Shares”) to be held in escrow under this Escrow Agreement in order to be made available for conversion by Purchaser under the Company's Series A 8% Convertible Redeemable Debenture due March 18, 2010 (the “Initial Debenture”) and the Company's Series A 8% Convertible Redeemable Debenture due July 3, 2010 in the principal amount of $15,000 (the “New Debenture” and together with the Initial Debenture, the “Debentures”);

WHEREAS, in order to induce the Purchaser to purchase the New Debenture and in order to comply with the terms of the Initial Debenture, the Company has agreed to execute this Escrow Agreement and to deliver the Escrow Shares as security for its performance under the Debentures and the Securities Sale Agreement between Purchaser and the Company dated as of March 18, 2008 (the “Sale Agreement”); and

WHEREAS, in the event that Purchaser exercises its rights of conversion under the  Debentures, the Escrow Shares shall be made available for such purpose under this Escrow Agreement.

1.           Appointment of Escrow Agent.  Escrow Agent is hereby appointed as escrow agent and the Escrow Agent hereby accepts such appointment.  The Escrow Agent shall act in accordance with the instructions set forth in this Escrow Agreement and any further instructions given to it by written instrument signed by Company and Purchaser.

2.           Escrow Shares Delivery and Application

(a)           On the date hereof the Company shall deposit in an account which the Escrow Agent maintains at a registered brokerage firm ("Brokerage Firm") issued in the name of Escrow Agent the Escrow Shares, which shall not contain any restrictive legend of any nature.

(b)           The Escrow Agent shall act solely as a stakeholder with respect to the Escrow Shares.  Accordingly, the Escrow Agent shall not have the power to vote the Escrow Shares, nor shall the Escrow Agent have any beneficial interest in the Escrow Shares.

(c)           Each notice of conversion of the Debenture (a “Notice of Conversion”) shall be simultaneously sent to the Company, as required by the terms of such Debenture and/or the Sale Agreement, and to the Escrow Agent.  In the event there are any errors or discrepancies in the Notice of Conversion, the Company and the Purchaser will cooperate fully in resolving such errors.  Upon Escrow Agent’s receipt of a copy of a Notice of Conversion and, provided that Escrow Agent has not received a notice from the Company indicating any errors or discrepancies in the Notice of Conversion, and, provided that Escrow Agent has not received a notice from the Company indicating any errors or discrepancies in the Notice of Conversion (in which event the Escrow Agent will promptly notify Purchaser of such notice and will use reasonable efforts assist the Company and Purchaser in resolving the issue), (i) the number of Escrow Shares set forth in the Notice of Conversion shall become the property of the Purchaser, and (ii) the Escrow Agent shall permit the Brokerage Firm to journal such shares over to the Purchaser's account at the Brokerage Firm or to such other account as the Purchaser shall direct. Until such Notice of Conversion is received, Purchaser shall have absolutely no right, title or interest in any of the Escrow Shares unless there is a Default or Event of Default (as defined in the Debentures).

(d)Purchaser shall have the right under this Escrow Agreement to send Notices of Conversion for either Debenture, and in any order selected by the Purchaser in its sole and absolute discretion, subject to the terms of the Debentures.

3.           Default

(a)           If Purchaser sends the Escrow Agent a Notice of Default under either Debenture, or if, for any reason, the Company is unable, fails or refuses to deliver common stock to Purchaser as required under the Debentures, the Escrow Agent shall then release all the Escrow Shares to the Purchaser.

(b)           Escrow Agent is specifically authorized to rely upon the validity and effectiveness of any Notice of Default, received by the Escrow Agent.

(c)           Upon payment in full by the Company of either Debenture, or upon conversion of both the Debentures into Conversion Shares (as such term is defined in the Debentures), any remaining Escrow Shares shall be delivered by the Escrow Agent to the Company, and upon such delivery, none of the parties to this Escrow Agreement shall have any further obligations to the others.  In the event that the Escrow Shares are delivered to the Purchaser upon an Event of Default, the Escrow Agent shall have no further obligations under this Escrow Agreement.

4.           Indemnification.  The Purchaser and the Company agree, jointly and severally, to indemnify, defend and hold harmless the Escrow Agent from and against any and all costs (including, without limitation, legal fees and expenses), liabilities, claims and losses arising out of or in connection with this Escrow Agreement or any action or failure to act by the Escrow Agent under this Escrow Agreement, except as provided in paragraph 5 below.

5.           Concerning the Escrow Agent.  To induce the Escrow Agent to act hereunder, it is further agreed by the undersigned that:

(a)           This Escrow Agreement expressly sets forth all the duties of the Escrow Agent with respect to any and all matters pertinent hereto.  No implied duties or obligations shall, on the part of the Escrow Agent, be read into this Escrow Agreement.  The Escrow Agent shall not be bound by the provisions of any agreement among the other parties hereto except this Escrow Agreement.

(b)           The Escrow Agent shall not be liable for any action or failure to act in its capacity as Escrow Agent hereunder unless such action or failure to act shall constitute willful misconduct on the part of the Escrow Agent, in which case there shall be no indemnification obligations.

(c)The Escrow Agent shall be entitled to rely upon any order, judgment, certification, demand, notice, instrument or other writing delivered to it hereunder without being required to determine the authenticity or the correctness of any fact stated therein or the propriety or validity of the service thereof.  The Escrow Agent may act in reliance upon any instrument or signature believed by it to be genuine and may assume, unless he has actual knowledge to the contrary, that any person purporting to give notice or receipt or advice or make any statement or execute any document in connection with the provisions hereof has been duly authorized to do so.

(d)           The Escrow Agent may act pursuant to the advice of counsel with respect to any matter relating to this Escrow Agreement and shall not be liable for any action taken or omitted in accordance with such advice, except as provided in paragraph 5(b) above.

(e)           The Escrow Agent does not have and shall not have any interest whatsoever in the Escrow Shares or any other property deposited hereunder but is serving as escrow holder only and having only possession thereof with no rights as a shareholder of the Company, and is not charged with any duty or responsibility to determine the validity or enforceability of any such documents.  Furthermore, the Escrow Agent shall have no right to vote the Escrow Shares or have any other pecuniary rights in the Escrow Shares or have control of, direct or indirect, or role in the Company’s corporate governance or otherwise.  The Escrow Agent may not assert any lien on the Escrow Shares for payment of any fee due the Escrow Agent.

(f)           The Escrow Agent (and any successor Escrow Agent) may at any time resign as such by delivering the Escrow Shares to any successor Escrow Agent, jointly designated by the other parties hereto in writing, or to any court of competent jurisdiction, whereupon the Escrow Agent shall be discharged of and from any and all further obligations arising in connection with this Escrow Agreement thereafter.  The resignation of the Escrow Agent will take effect on the earlier of (a) the appointment of a successor (including a court of competent jurisdiction) or (b) the day which is 30 days after the date of delivery of its written notice of resignation to the other parties hereto.  If at that time the Escrow Agent has not received a designation of a successor Escrow Agent, the Escrow Agent's sole responsibility after that time shall be to safekeep the Escrow Shares and not make delivery or disposition thereof until receipt of a designation of successor Escrow Agent or a joint written disposition instruction by the other parties hereto or a final order of a court of competent jurisdiction.

(g)           In the event of any disagreement among the parties hereto resulting in adverse claims or demands being made in connection with the Escrow Shares, or in the event that the Escrow Agent otherwise determines that the Escrow Shares should be retained, then the Escrow Agent may retain the Escrow Shares until the Escrow Agent shall have received (i) a final nonappealable order of a court of competent jurisdiction directing delivery of the Escrow Shares or (ii) a written agreement executed by the other parties hereto directing delivery of the Escrow Shares, in which case the Escrow Agent shall promptly deliver the Escrow Shares in accordance with such order or agreement.  Any court order referred to in (i) above shall be accompanied by a legal opinion by counsel for the presenting party reasonably satisfactory to the Escrow Agent to the effect that said court order is final and nonappealable.  The Escrow Agent shall act on such court order and legal opinion without further question.

(h)           This Escrow Agreement shall be binding upon and inure solely to the benefit of the parties hereto and their respective successors (including successors by way of merger) and assigns, heirs, administrators and representatives, and shall not be enforceable by or inure to the benefit of any third party except as provided in paragraph (g) with respect to a resignation by the Escrow Agent.

(i)           This Escrow Agreement may be modified by a writing signed by all the parties hereto, and no waiver hereunder shall be effective unless in a writing signed by the party to be charged.

6.           Consent to Jurisdiction.  Company, Purchaser and the Escrow Agent hereby irrevocably consent to the jurisdiction of any federal or state court, in Northern California, in any action or proceeding arising out of or relating to this Escrow Agreement.  Company hereby irrevocably waives, to the fullest extent possible, the defense of an inconvenient forum to the maintenance of such action or proceeding.  Service of process may be effectuated by certified mail, return receipt requested, or by Federal Express with evidence of delivery to the parties at the addresses set forth in Section 9 below.

COMPANY, ESCROW AGENT AND PURCHASER HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY AND ALL RIGHTS TO A TRIAL BY JURY IN ANY ACTION, SUIT OR COUNTERCLAIM, ARISING IN CONNECTION WITH, OUT OF OR OTHERWISE RELATING TO THIS ESCROW AGREEMENT.  COMPANY SHALL NOT RAISE ANY COUNTERCLAIM IN ANY PROCEEDING BROUGHT BY PURCHASER TO ENFORCE THE PROVISIONS OF THIS ESCROW AGREEMENT.
