(a) On or before May 16, 2008, QRSciences shall deposit the amount of $50,000 (the “Deposit”) with Laura Anthony, Esquire of Legal & Compliance, LLC (the “Seller Escrow Agent”) pursuant to the escrow terms between QRSciences, Seller and the Seller Escrow Agent provided herein.

(b) The Deposit shall be released by the Seller Escrow Agent to Seller in the event the Agreement is terminated by Seller pursuant to Section 9.1(c).

(c) The Deposit shall be released by the Seller Escrow Agent to QRSciences in the event the Agreement is terminated for any reason other than by Seller pursuant to Section 9.1(c); provided, however, if this Agreement is terminated for any reason whatsoever other than by QR Sciences pursuant to Section 9.1(b) or (d) at any time after DVOP files the Schedule 14(f)-1 as provided in Section 5.1, the Deposit shall be released by the Seller Escrow Agent to Seller.

(d) On or prior to the Closing Date, QRSciences shall have deposited the amount of $600,000 into the escrow account maintained by Steven James Davis, a Professional Corporation (the “QRSciences Escrow Agent”). On or prior to the Closing Date, the Seller Escrow Agent shall have delivered to the QRSciences Escrow Agent each of the Seller deliverables described in Section 2.2(a), who shall simultaneously deliver the amount of $600,000 to the Seller Escrow Agent.

(e) The Seller Escrow Agent and QR Sciences Escrow Agent (each, the “Escrow Agent”) shall perform his or her obligations hereunder subject to the following provisions.

(i) Scope of Duties. The duties of the Escrow Agent shall be entirely administrative in nature, and the Escrow Agent shall have no fiduciary obligation to any party hereto. The Escrow Agent shall be obligated to act only in accordance with written instructions received by him or her as provided herein, except that the Escrow Agent shall comply with any final and unappealable order, judgment or decree of any court of competent jurisdiction received by him. No implied duties or obligations of any kind shall be read into this Agreement.

(ii) Limitation on Liability. In performing his/her duties hereunder, the Escrow Agent shall not incur any liability to anyone for any damages, losses or expenses except for damages, losses or expenses resulting directly from the willful default, gross negligence or fraud of the Escrow Agent. In no event will the Escrow Agent be liable for any special, consequential or punitive damages.

(iii) Reliance on Counsel, etc. The Escrow Agent shall not in any case incur liability with respect to any action taken or omitted in good faith upon advice of counsel, or any action taken or omitted in reliance upon any written notice, release or other document provided to the Escrow Agent as to the genuineness of the signatures thereon, the authority of the signatories, its due execution, the validity and effectiveness of its provisions, or the truth and accuracy of the information contained therein.

(iv) Indemnification of Escrow Agent; Expenses. The Escrow Agent shall not be responsible for initiating any action, claim or proceeding hereunder. QRSciences and the Seller shall jointly and severally indemnify the Escrow Agent (and his/her heirs and legal representatives) and hold him/her and them harmless from and against, any and all losses, damages, liability and expenses, including attorneys fees, incurred by the Escrow Agent in connection with the performance of his/her duties hereunder, including but not limited to attorneys’ fees and other costs and expenses of defending against any claim of liability (except liability arising out of the Escrow Agent’s fraud, willful default or gross negligence) arising out of this Agreement. The Escrow Agent shall not be obligated to take any legal or other action hereunder which might, in his/her judgment, involve or cause him/her to incur any expense or liability unless s/he shall have been furnished with acceptable indemnification.

(v) Disputes. In the event of any dispute between the parties, or if any conflicting demand shall be made upon the Escrow Agent, the Escrow Agent shall not be required to determine the same or take any action thereon.

Confidential 2

documents without liability to anyone, until such dispute shall have been settled or resolved; or (b) file a suit in interpleader for the purpose of having the respective rights of the parties adjudicated, said suit to be filed in the California Superior Court if filed by the QR Sciences Escrow Agent and the Florida Court if filed by the Seller Escrow Agent.

(vi) Resignation. The Escrow Agent may resign at any time by delivering notice to the parties hereto. If the parties fail to advise the Escrow Agent within ten business days as to the appointment of a successor, the Escrow Agent may, at his/her sole option, (a) retain the escrowed funds and DVOP Shares and closing documents in his/her possession, without liability to anyone, until such appointment shall have been made; or (b) file a suit in interpleader in the California or Florida Court, as appropriate, for the purpose of having a successor appointed. The Escrow Agent may, upon initiation of such suit, deposit the escrowed funds and DVOP Shares and closing documents with the court and, upon giving notice thereof to the parties, the Escrow Agent shall be fully released and discharged from all further obligations hereunder.

(vii) Waiver. The parties are aware that the Seller Escrow Agent represents Seller and Anthony and the QRSciences Escrow Agent represents QRSciences. The parties agree that each Escrow Agent may carry on such representation in connection with this Agreement and, after the Closing, may represent the parties in connection with this Agreement and in other related or unrelated matters. The parties acknowledge that the Escrow Agent is serving at their joint request, and each waives any objection thereto.

Confidential 15

agreements made by Anthony or Seller, (iii) any misrepresentation made by Anthony or Seller, in each case as made herein or in the Exhibits annexed hereto or in any closing certificate, schedule or any ancillary certificates or other documents or instruments furnished by Anthony pursuant hereto or in connection with the Acquisition, (iv) any untimely filing of, or inaccuracy in, any DVOP SEC Document, and (v) the operations and liabilities of DVOP and/or any of its subsidiaries, whether known or unknown, arising out of any action, omission and/or period of time preceding the Closing Date, including but not limited to any taxes or creditor claims levied with respect to same.

(a) Upon obtaining knowledge of any Claim by a third party which has given rise to, or is expected to give rise to, a claim for indemnification hereunder, the Indemnified Party shall give written notice (“Notice of Claim”) of such claim or demand to the Indemnifying Party, specifying in reasonable detail such information as the Indemnified Party may have with respect to such indemnification claim (including copies of any summons, complaint or other pleading which may have been served on it and any written claim, demand, invoice, billing or other document evidencing or asserting the same). No failure or delay by the Indemnified Party in the performance of the foregoing shall reduce or otherwise affect the obligation of the Indemnifying Party to indemnify and hold the Indemnified Party harmless, except to the extent that such failure or delay shall have actually adversely affected the Indemnifying Party’s ability to defend against, settle or satisfy any Claims for which the Indemnified Party entitled to indemnification hereunder.

(b) If the claim or demand set forth in the Notice of Claim given by an Indemnified Party pursuant to Section 8.1 hereof is a claim or demand asserted by a third party, the Indemnifying Party shall have fifteen (15) days after the date on which Notice of Claim is given to notify Indemnified Party in writing of their election to defend such third party claim or demand on behalf of the Indemnified Party. If the Indemnifying Party elects to defend such third party claim or demand, Indemnified Party shall make available to the Indemnifying Party and its agents and representatives all records and other materials that are reasonably required in the defense of such third party claim or demand and shall otherwise cooperate with, and assist the Indemnifying Party in the defense of, such third party claim or demand, and so long as the Indemnifying Party is defending such third party claim in good faith, the Indemnified Party shall not pay, settle or compromise such third party claim or demand. If the Indemnifying Party elects to defend such third party claim or demand, the Indemnified Party shall have the right to participate in the defense of such third party claim or demand, at such Indemnified Party’s own expense. In the event, however, that such Indemnified Party reasonably determines that representation by counsel to the Indemnifying Party of both the Indemnifying Party and such Indemnified Party could reasonably be expected to present counsel with a conflict of interest, then the Indemnified Party may employ separate counsel to represent or defend it in any such action or proceeding and the Indemnifying Party will pay the fees and expenses of such counsel. If the Indemnifying Party does not elect to defend such third party claim or demand or do not defend such third party claim or demand in good faith, the Indemnified Party shall have the right, in addition to any other right or remedy it may have hereunder, at the Indemnifying Party’s expense, to defend such third party claim or demand; provided, however, that (i) such Indemnified Party shall not have any obligation to participate in the defense of, or

Confidential 16

defend, any such third party claim or demand; (ii) such Indemnified Party’s defense of or its participation in the defense of any such third party claim or demand shall not in any way diminish or lessen the obligations of the Indemnifying Party under the agreements of indemnification set forth in this Article VII; and (iii) such Indemnified Party may not settle any claim without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed.

(c) The Indemnifying Party and the other Indemnified Parties, if any, shall cooperate fully in all aspects of any investigation, defense, pre-trial activities, trial, compromise, settlement or discharge of any claim in respect of which indemnity is sought pursuant to this Article VIII, including, but not limited to, by providing the other party with reasonable access to employees and officers (including as witnesses) and other information.

Section 8.3 Indemnification Procedures for Non-Third Party Claims. In the event any Indemnified Party should have an indemnification claim against the Indemnifying Party under this Agreement that does not involve a claim by a third party, the Indemnified Party shall promptly deliver notice of such claim to the Indemnifying Party in writing and in reasonable detail. The failure by any Indemnified Party to so notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability that it may have to such Indemnified Party, except to the extent that Indemnifying Party has been actually prejudiced by such failure. If the Indemnifying Party does not notify the Indemnified Party within fifteen (15) Business Days following its receipt of such notice that the Indemnifying Party disputes such claim, such claim specified by the Indemnifying Party in such notice shall be conclusively deemed a liability of the Indemnifying Party under this Article VIII and the Indemnifying Party shall pay the amount of such liability to the Indemnified Party on demand, or in the case of any notice in which the amount of the claim is estimated, on such later date when the amount of such claim is finally determined. If the Indemnifying Party disputes its liability with respect to such claim in a timely manner, QRSciences and the Indemnified Party shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved pursuant to Section 10.11.

Section 8.4 Limitations on Indemnification. Except with respect to claims for indemnification relating to or arising out of a breach of the representations, warranties or covenants made by Seller contained in Sections 1.2(a), 3.3, 3.4 or 3.7 which may be asserted at any time, no claim for indemnification under this Article VIII shall be asserted by, and no liability for such indemnify shall be enforced against, the Indemnifying Party following a date twelve months from the date of Closing. No claim for indemnification under this Article VIII shall be asserted by, and no liability for such indemnify shall be enforced against, the Indemnifying Party to the extent the Indemnified Party has theretofore received indemnification or otherwise been compensated for such Claim. In the event that an Indemnified Party shall later collect any such amounts recovered under insurance policies with respect to any Claim for which it has previously received payments under this Article VIII from the Indemnifying Party, such Indemnified Party shall promptly repay to the Indemnifying Party such amount recovered.
