EXPLANATORY NOTE

We are reporting a change of corporate name from "Used Kar Parts, Inc." and a 111 for 1 stock split and other matters related to our acquisition of Xenomics, a California corporation on July 2, 2004. The stock split will be effective under Florida law on July 26, 2004. All references to number of our shares in this report have been adjusted as if the split had already occurred, unless otherwise indicated.

Item 1. Changes in Control of the Registrant.

We completed the acquisition of Xenomics, an unaffiliated California corporation on July 2, 2004 by issuing 2,258,001 shares of our common stock to Xenomics' five shareholders in exchange for all outstanding shares of Xenomics stock (the "Exchange"). The Exchange was made according to the terms of a Securities Exchange Agreement dated May 18, 2004 ("Exchange Agreement"), which we filed as an exhibit to a Form 8-K dated May 18, 2004.

We also completed a private placement of 2,645,210 shares of our common stock for aggregate proceeds of $2,512,949.50. The sale was made to 17 accredited investors ("Investors") directly by us without any general solicitation or broker. We filed a Form D with the Securities and Exchange Commission ("SEC") and the offering is claimed to be exempt from registration pursuant to Rule 506 of Regulation D under the Securities Act of 1933, as amended.

As part of the Acquisition, we:

o redeemed 1,971,734 pre-split shares (the equivalent of 218,862,474 post-split shares) from Panetta Partners Ltd., a principal shareholder, for $500,000 or $0.0023 per share.

o amended our articles of incorporation to change our corporate name to "Xenomics, Inc." and to split our stock outstanding prior to the redemption 111 for 1 (effective July 26, 2004).

o entered into employment agreements with two of the former Xenomics shareholders and a consulting agreement with one of the former Xenomics shareholders.

o entered into a Voting Agreement with the Investors, the former Xenomics shareholders and certain principal shareholders.

o entered into a Technology Acquisition Agreement with the former Xenomics shareholders under which we granted an option to the former Xenomics holders to acquire Xenomics technology if we fail to apply at least 50% of all financing we raise to the development of Xenomics technology during the period ending July 1, 2006 in exchange for all of our shares and share equivalents held by the former Xenomics holders at the time such option is exercised.

2

Each of the above agreements is filed with this report and the above summary is qualified by reference to the complete documents.

As a result of the above transactions, we have 15,588,737 shares outstanding.

We appointed L. David Tomei, Samuil Umansky, Gary Jacobs and Donald Picker to be directors according to the terms of the Voting Agreement and Mr. Tomei was appointed Chairman of the Board. Samuil Umansky was appointed President and Chief Scientific Officer and Christoph Bruening remains Secretary and Treasurer.

Exhibit 99.1 to this report (which will be filed by amendment) is a descriptive memorandum that contains additional information about Xenomics and our company.

Item 2. Acquisition or Disposition of Assets.

See Item 1. above for a description of the material terms of the Exchange Agreement under which Xenomics became our wholly owned subsidiary.

The terms of the Exchange Agreement, including the relative number of our shares to be issued to the holders of Xenomics stockholders was determined by arms length negotiation between our management and Xenomics. We intend to continue utilizing the assets of Xenomics in their efforts to develop diagnostic tests utilizing transrenal nucleic acids for prenatal diagnosis, cancer detection and transplantation compatibility.

Item 5. Other Events and Required FD Disclosure.

We adopted a 2004 Stock Option Plan which is filed as an Exhibit to this report. We issued options to acquire 3,750,000 shares of our common stock to officers and consultants for $1.25 per share.

Item 7. Financial Statements, Pro Forma Financial Information and Exhibits.

(a) Financial statements that may be required by this item are not included in this report and will, if applicable, be filed by amendment within 60 days of the date of the filing of this report.

THIS SHAREHOLDER ESCROW AGREEMENT is made effective as of the 24th day of June, 2004, by and among Used Kar Parts, Inc., a Florida corporation ("Purchaser"), Sommer & Schneider LLP, as escrow agent (the "Escrow Agent"), and the several former shareholders of Xenomics, a California corporation ("Xenomics") identified on Schedule A attached hereto ("Shareholders").

W I T N E S S E T H:

WHEREAS, pursuant a Securities Exchange Agreement (the "Exchange Agreement") dated effective as of the date hereof, among Purchaser, Xenomics and the Shareholders, Purchaser has acquired or will acquire all of the outstanding capital stock of Xenomics (the "Xenomics Acquisition").

WHEREAS, in connection with the Xenomics Acquisition, the Shareholders, collectively, will receive 2,258,001 shares of Purchaser's common stock, par value $0.001 per share (the "Purchaser Shares") in exchange for their shares of Xenomics;

WHEREAS, the Exchange Agreement provides that on the Closing Date (as defined in the Exchange Agreement), 300,000 Purchaser Shares issued to the Shareholders in exchange for their Xenomics shares (the "Escrowed Shares") shall be deposited in escrow, together with stock powers endorsed in blank (the "Escrow Deposit"), to be held and disposed of by the Escrow Agent as provided herein; and

WHEREAS, Purchaser and the Shareholders wish to appoint the Escrow Agent to serve as the escrow agent hereunder, and the Escrow Agent is willing to do so upon the terms and conditions hereinafter set forth.

NOW THEREFORE, it is agreed:

Section 1 APPOINTMENT OF ESCROW AGENT; CREATION OF ESCROW DEPOSIT

1.1 Appointment of Escrow Agent. Purchaser and the Shareholders hereby appoint the Escrow Agent, and the Escrow Agent hereby agrees to act, as depository and administrator of the Escrow Deposit, upon the terms and conditions set forth below.

1.2 Creation of Escrow Deposit. Promptly following the execution and delivery of this Agreement, Purchaser, pursuant to the Exchange Agreement, shall deliver to the Escrow Agent, for deposit into the Escrow Deposit, the Escrowed Shares and each Shareholder will deliver 5 duly executed guarantied stock powers for the transfer of Escrowed Shares to the Purchaser.

Section 2 DISPOSITION OF ESCROW DEPOSIT

2.1 Term of Escrow Deposit.

(a) The Escrowed Shares held in the Escrow Deposit shall be held by the Escrow Agent on the terms and subject to the conditions set forth herein and in the Exchange Agreement (but the Escrow Agent shall have no responsibility with respect to the Exchange Agreement other than to perform as provided in this Agreement) to satisfy the indemnification obligations of Xenomics and the Shareholders pursuant to the Exchange Agreement.

(b) The Escrowed Shares held in the Escrow Deposit shall be held by the Escrow Agent on the terms and subject to the conditions set forth herein and in the Exchange Agreement until the first anniversary of the Closing Date or, if earlier, the date of the expiration in their entirety of the representations and warranties of Purchaser pursuant to Article 2 of the Exchange Agreement (either date referred to hereinafter as the "Expiration Date"). On the Expiration Date, the Escrow Agent shall release the remaining Escrow Deposit to Shareholders on a pro rata basis as required by Section 4.2 of the Exchange Agreement, subject in all cases to the terms and conditions set forth in Sections 2.7 and 2.8.

(c) "Escrowed Shares" shall mean the shares of Purchaser's common stock delivered to the Escrow Agent under this Section 2 together with all shares or other securities, if any, received by the Escrow Agent as a dividend or distribution paid or made on or in respect of said shares of Purchaser's common stock or on or in respect of any other shares or securities so received by the Escrow Agent.

2.2 Purchaser Indemnity Claims. Upon the occurrence of an event which Purchaser asserts constitutes an event for which Shareholders would be required to indemnify or make any payment to the Purchaser pursuant to the Exchange Agreement (a "Purchaser Indemnity Claim"), the Purchaser shall furnish notice of such event (the "Indemnity Notice") to the Shareholders and the Escrow Agent promptly (and in any event on or prior to the Expiration Date), setting forth the Purchaser's then good-faith estimate of the reasonably foreseeable maximum amount of the Purchaser Indemnity Claim. Upon final determination of the amount of the Purchaser Indemnity Claim, the Purchaser shall furnish an additional notice (the "Determination Notice") to the Shareholders and the Escrow Agent promptly, setting forth the final amount of the Purchaser Indemnity Claim and proof of such amount by documentary evidence.

2.3 Purchaser Indemnity Claims Not Disputed by Shareholders. Upon delivery of the Indemnification Notice, Escrow Agent shall retain for transfer to the Purchaser, pro rata from each of the Shareholders that number of Escrowed Shares derived by dividing the amount of the Purchaser Indemnity Claim set forth in the Indemnity Notice by $1.25 or such other amount adequately reflecting any stock split, stock exchange, or stock dividend paid or made on or in respect of the Escrowed Shares after the Closing Date. If, within thirty (30) days after receipt of the Indemnity Notice or Determination Notice, the record holders of a majority of the Escrowed Shares (the "Majority Shareholders") do not give the notice provided for in Section 2.4, Escrow Holder shall transfer to Purchaser that number of Escrowed Shares derived by dividing the final amount of the

2

Purchaser Indemnity Claim set forth in the Determination Notice by $1.25 or such other amount adequately reflecting any stock split, stock exchange, or stock dividend paid or made on or in respect of the Escrowed Shares after the Closing Date.

2.4 Purchaser Indemnity Claims Disputed by Shareholders in Whole. If Majority Shareholders dispute either the Purchaser Indemnity Claim described in the Indemnity Notice or the final amount set forth in the Determination Notice, the Majority Shareholders shall, within thirty (30) days after receipt of the Indemnity Notice or Determination Notice, as the case may be, notify the Escrow Agent and the Purchaser of such dispute, setting forth the basis therefor in reasonable detail, based on its then good-faith belief. In the event Majority Shareholders dispute the entire Purchaser Indemnity Claim, the Escrow Agent shall not transfer any Escrowed Shares to Purchaser until the Escrow Agent receives a written agreement signed by the Majority Shareholders and Purchaser stating the amount to which the Purchaser is entitled in connection with such Purchaser Indemnity Claim, or a copy of a court order or judgment together with an opinion of counsel reasonably acceptable to the Escrow Agent to the effect that such order or judgment is a final order or judgment of a court of competent jurisdiction binding on Purchaser and the Shareholders from which no appeal may be taken or for which the time to appeal has expired (a "Final Judgment"), at which time the Escrow Agent shall transfer to the Purchaser the amount of Escrowed Shares derived by dividing the amount set forth in such agreement or Final Judgment by $1.25 or such other amount adequately reflecting any stock split, stock exchange, or stock dividend paid or made on or in respect of the Escrowed Shares after the Closing Date .

2.5 Purchaser Indemnity Claims Disputed by Majority Shareholders in Part. In the event the Majority Shareholders dispute part of, but not all of, a Purchaser Indemnity Claim, the Escrow Agent shall transfer to the Purchaser, that number of Escrowed Shares attributable to that portion of the Purchaser Indemnity Claim which is not disputed by the Majority Shareholders up to the entire amount of the Escrowed Shares. The Escrow Agent shall not transfer any Escrowed Shares with respect to the balance of such Purchaser Indemnity Claim except in accordance with the procedures set forth in Section 2.4.

2.6 Notice to Withhold on the Expiration Date. On or prior to the Expiration Date, the Purchaser shall furnish notice (the "Withholding Notice") to the Escrow Agent and Shareholders of the number of Escrowed Shares to be retained on account of Purchaser Indemnity Claims for which an Indemnity Notice, but no Determination Notice has been provided pursuant to Section 2.2, or for which an Indemnity Notice and a Determination Notice has been provided pursuant to Section 2.2, but either notice has been disputed by the Majority Shareholder in full or in part pursuant to Section 2.4 (the "Withholding Shares"). The Withholding Notice shall contain the information specified in Section 2.2 to the extent it requires supplementation or change based on the Purchaser's knowledge on the notice date. Upon the receipt by the Escrow Agent of the Withholding Notice, the Escrow Agent shall retain the Withholding Shares. In the event the Purchaser does not timely provide the Withholding Notice, any remaining Escrowed Shares shall be distributed by the Escrow Agent to Shareholders in accordance with, and to the extent provided in, Section 2.7.

2.7 Distribution of the Escrow Deposit. As soon as practicable following the Expiration Date, any Escrowed Shares as shall remain in the Escrow Deposit after deduction of Escrowed Shares pursuant to the provisions of

3

Sections 2.3 and 2.5 hereof, and after deduction of Withholding Shares, if any, shall be released from the provisions of this Agreement and distributed promptly by the Escrow Agent to the Shareholders, pro rata.

2.8 Retention of Withholding Shares After Expiration Date. Upon receipt of the Withholding Notice, the Escrow Agent shall continue to hold after the Expiration Date, the Withholding Shares until such time as the Escrow Agent receives a written agreement signed by the Majority Shareholders and Purchaser stating the number of Withholding Shares, if any, to which the Purchaser is entitled in connection with any outstanding Purchaser Indemnity Claims identified in the Withholding Notice, or a copy of a Final Judgment with respect to such Purchaser Indemnity Claims. As soon as practicable following the receipt of such agreement or Final Judgment, Escrow Agent shall transfer to the Purchaser the number of Payoff Shares specified in such agreement or Final Judgment and, unless there are any additional unresolved Purchaser Indemnity Claims outstanding that were identified in the Withholding Notice, shall distribute to the Shareholders any remaining Escrow Deposit.

2.9 Reservation of the Shareholders' Rights. The rights of the Purchaser to receive disbursements from the Escrow Account in respect of Purchaser Indemnity Claims shall be without prejudice to any other rights the Purchaser may have, under the Exchange Agreement or otherwise, to seek indemnity for Purchaser Indemnity Claims.

2.10 Reporting. The parties hereto shall, for federal income tax purposes and, to the extent permitted by applicable law, state and local tax purposes, report consistent with the Shareholders as the owners of the Escrowed Shares and the Shareholders shall furnish any required tax forms consistent with the foregoing.

2.11 Voting and Dispositive Authority. The Shareholders shall retain full voting authority with respect to the Escrowed Shares. The Shareholders shall not dispose of the Escrowed Shares until the time such shares have been returned to them by Escrow Agent in accordance with this Agreement.

The Escrow Agent shall be entitled to consult with counsel of its choosing (including internal counsel) and shall not be liable for any act suffered or omitted by it in good faith in accordance with the advice of such counsel.

3.4 Disputes. In the event that the Escrow Agent shall be uncertain as to its duties or rights hereunder, or shall receive instructions from any party hereto with respect to the Escrow Deposit which, in its opinion, are in conflict with any of the provisions of this Agreement, it shall be entitled to refrain from taking any action until such time as there has been a final determination of the rights of Purchaser and the Shareholders with respect to the Escrow Deposit (or relevant portion thereof). For purposes of this Section 3.4, there shall be deemed to have been a final determination of the rights of Purchaser and the Shareholders with respect to the Escrowed Shares (or relevant portion thereof) at such time as Escrow Agent shall receive (i) an executed counterpart of an agreement between the Majority Shareholders and Purchaser or (ii) a copy of a Final Judgment which provides for the disposition of the Escrow Deposit (or relevant portion thereof).

3.5 Resignation. The Escrow Agent may resign at any time and be discharged of the duties imposed hereunder (but without prejudice for any liability in the case of its bad faith, gross negligence or willful misconduct hereunder) by giving notice to the Majority Shareholders and Purchaser at least sixty (60) business days prior to the date specified for such resignation to take effect, in which case, upon the effective date of such resignation:

(a) any property then held by the Escrow Agent hereunder shall be delivered by it to such person as may be designated in writing by Purchaser and the Majority Shareholders, whereupon the Escrow Agent's obligations hereunder shall cease and terminate;

(b) if no such person has been designated by such date, all obligations of the Escrow Agent hereunder shall, nevertheless, cease and terminate, subject to clause (c) below; and

(c) the Escrow Agent's sole responsibility thereafter shall be to keep all property then held by it (and to make the investments as hereinbefore provided) and to deliver the same to the successor escrow agent designated in writing by Purchaser and the Majority Shareholders or, if no such successor escrow agent shall have been so designated, in accordance with the directions of a Final Judgment, and the provisions of Section 3.7 and Section 3.8 shall remain in effect.

3.6 Removal of Escrow Agent. Purchaser and the Majority Shareholders may, upon at least thirty (30) business days prior written notice to the Escrow Agent, dismiss the Escrow Agent hereunder and appoint a successor. In such event, the Escrow Agent shall promptly account for and deliver to the successor escrow agent named in such notice the balance of the Escrow Deposit, including all investments thereof and accrued income thereon, on the date of such accounting and delivery. Upon acceptance thereof and of such accounting by such successor escrow agent, and upon reimbursement to the Escrow Agent of all expenses due to it hereunder through the date of such accounting and delivery, the Escrow Agent shall be released and discharged from all of its duties and

5

obligations hereunder, but without prejudice to any liability of the Escrow Agent for its bad faith, gross negligence or willful misconduct hereunder.

3.7 Indemnification. Each of Purchaser and the Shareholders shall jointly indemnify and hold the Escrow Agent harmless against any loss, liability, claim, damage, injury, demand or expense, including reasonable legal fees, arising out of or in connection with the performance of the Escrow Agent's obligations hereunder, including the costs and expenses incurred in connection with the collection of its fees and including the costs and expenses of defending itself against any claim or liability arising out of or in connection with the performance of its duties hereunder, except for any loss, liability, claim, damage, injury, demand or expense resulting from the Escrow Agent's bad faith, gross negligence or willful misconduct; provided, however, that promptly after the receipt by the Escrow Agent of notice of any claim or the commencement of any suit, action or proceeding, the Escrow Agent shall, if a claim of indemnification in respect thereof is to be made against any of the other parties hereto, notify such other parties thereof in writing; and provided, further, that the indemnifying party or parties shall be entitled, jointly or severally and at their own expense, to participate in or assume the defense of any such action, suit or proceeding. The right of the Escrow Agent (or any successor escrow agent appointed hereunder) to indemnification under this
Section 3.7 shall survive the termination of this Agreement.

3.8 Sommer & Schneider LLP.

(a) Each party acknowledges that Sommer & Schneider LLP has acted as legal counsel to and representative of Purchaser and its affiliates in the past and is presently doing so (including, without limitation, in connection with the Exchange Agreement and other related transactions), and agrees that such counsel and representation do not and will not constitute a grounds for disqualifying Sommer & Schneider LLP from acting as Escrow Agent hereunder, and that Sommer & Schneider LLP may continue to so act as legal counsel to and representative to Purchaser and its affiliates in the future in connection with those and all other matters.

(b) Notwithstanding anything to contrary contained herein, it is expressly understood by the parties hereto that the Escrow Agent, in that capacity, at any time that it is required or permitted to seek legal counsel under this Agreement, may seek such legal counsel from Sommer & Schneider LLP, and that the Purchaser and the Shareholders will be jointly liable to Sommer & Schneider LLP for any services performed and billed to the Escrow Agent by Sommer & Schneider LLP at its customary hourly rates and all of Sommer & Schneider LLP's disbursements in connection with the provision of such services.

Exhibit 2.5
PURCHASER ESCROW AGREEMENT

(Contingent Shares)

THIS ESCROW AGREEMENT is made effective as of the 24th day of June, 2004, by and among Used Kar Parts, Inc., a Florida corporation ("Purchaser"), Sommer & Schneider LLP, as escrow agent (the "Escrow Agent"), and the several former shareholders of Xenomics, a California corporation ("Xenomics") identified on Schedule A attached hereto ("Shareholders").

W I T N E S S E T H:

WHEREAS, pursuant a Securities Exchange Agreement (the "Exchange Agreement") dated as of the date hereof, among Purchaser, Xenomics and the Shareholders, Purchaser has acquired or will acquire all of the outstanding capital stock of Xenomics (the "Xenomics Acquisition").

WHEREAS, in connection with the Xenomics Acquisition, the Shareholders collectively will receive 2,258,001 shares of Purchaser's common stock, par value $0.001 per share (the "Purchaser Shares") in exchange for their shares of Xenomics;

WHEREAS, the Exchange Agreement provides that on the Closing Date (as defined in the Exchange Agreement), 350,000 additional Purchaser Shares are being issued (the "Contingent Shares") and deposited in escrow, together with stock powers endorsed in blank (the "Escrow Deposit"), to be held and disposed of by the Escrow Agent as provided herein; and

WHEREAS, Purchaser and the Shareholders wish to appoint the Escrow Agent to serve as the escrow agent hereunder, and the Escrow Agent is willing to do so upon the terms and conditions hereinafter set forth.

NOW THEREFORE, it is agreed:

Section 1
APPOINTMENT OF ESCROW AGENT; CREATION OF ESCROW DEPOSIT

1.1 Appointment of Escrow Agent. Purchaser and the Shareholders hereby appoint the Escrow Agent, and the Escrow Agent hereby agrees to act, as depository and administrator of the Escrow Deposit, upon the terms and conditions set forth below.

1.2 Creation of Escrow Deposit. Promptly following the execution and delivery of this Agreement, Purchaser, pursuant to the Exchange Agreement, shall deliver to the Escrow Agent, for deposit into the Escrow Deposit, the Contingent Shares and Purchaser will deliver 5 duly executed guarantied stock powers, for the transfer of Contingent Shares to each Shareholder.


Section 2
DISPOSITION OF ESCROW DEPOSIT

2.1 Term of Escrow Deposit.

(a) The Contingent Shares held in the Escrow Deposit shall be held by the Escrow Agent on the terms and subject to the conditions set forth herein and in the Exchange Agreement (but the Escrow Agent shall have no responsibility with respect to the Exchange Agreement other than to perform as provided in this Agreement) to satisfy the indemnification obligations of Purchaser pursuant to the Exchange Agreement.

(b) The Contingent Shares held in the Escrow Deposit shall be held by the Escrow Agent on the terms and subject to the conditions set forth herein and in the Exchange Agreement until the first anniversary of the Closing Date or, if earlier, the date of the expiration in their entirety of the representations and warranties of Purchaser pursuant to Article 2 of the Exchange Agreement (either date referred to hereinafter as the "Expiration Date"). On the Expiration Date, the Escrow Agent shall release the remaining Escrow Deposit to Purchaser, for cancellation of the Contingent Shares as required by Section 4.2 of the Exchange Agreement, subject in all cases to the terms and conditions set forth in Sections 2.7 and 2.8.

(c) "Contingent Shares" shall mean the shares of Purchaser's common stock delivered to the Escrow Agent under this Section 2 together with all shares or other securities or property, if any, received by the Escrow Agent as a dividend or distribution paid or made on or in respect of said shares of Purchaser's common stock or on or in respect of any other shares or securities so received by the Escrow Agent.

2.2 Xenomics Indemnity Claims. Upon the occurrence of an event which the record holders of a majority of the Purchaser Shares among the Shareholders (the "Majority Shareholders") assert constitutes an event for which Purchaser would be required to indemnify or make any payment to Xenomics or the Shareholders pursuant to the Exchange Agreement (a "Xenomics Indemnity Claim"), the Majority Shareholders shall furnish notice of such event (the "Indemnity Notice") to the Purchaser and the Escrow Agent promptly (and in any event on or prior to the Expiration Date), setting forth the Majority Shareholders' then good-faith estimate of the reasonably foreseeable maximum amount of the Xenomics Indemnity Claim. Upon final determination of the amount of the Xenomics Indemnity Claim, the Majority Shareholders shall furnish an additional notice (the "Determination Notice") to the Purchaser and the Escrow Agent promptly, setting forth the final amount of the Xenomics Indemnity Claim and proof of such amount by documentary evidence.

2.3 Xenomics Indemnity Claims Not Disputed by Purchaser. Upon delivery of the Indemnification Notice, Escrow Agent shall retain for transfer to the Shareholders, pro rata from the Purchaser that number of Contingent Shares derived by dividing the amount of the Xenomics Indemnity Claim set forth in the Indemnity notice by $1.25 or such other amount adequately reflecting any stock split, stock exchange, or stock dividend paid or made on or in respect of the Contingent Shares after the Closing Date. If, within thirty (30) days after receipt of the Indemnity Notice or Determination Notice, Purchaser does not give

2

the notice provided for in Section 2.4, the Escrow Agent shall transfer to the Shareholders, pro rata, that number of Contingent Shares derived by dividing the final amount of the Xenomics Indemnity Claim set forth in the Determination Notice by $1.25 or such other amount adequately reflecting any stock split, stock exchange, or stock dividend paid or made on or in respect of the Contingent Shares after the Closing Date.

2.4 Xenomics Indemnity Claims Disputed by Purchaser in Whole. If Purchaser disputes either the Xenomics Indemnity Claim described in the Indemnity Notice or the final amount set forth in the Determination Notice, Purchaser shall, within thirty (30) days after receipt of the Indemnity Notice or the Determination Notice, as the case may be, notify the Escrow Agent and the Majority Shareholders of such dispute, setting forth the basis therefor in reasonable detail, based on its then good-faith belief. In the event Purchaser disputes the entire Xenomics Indemnity Claim, the Escrow Agent shall not transfer any Contingent Shares to Shareholders with respect thereto until the Escrow Agent receives a written agreement signed by the Majority Shareholders and Purchaser stating the amount to which the Shareholders are entitled in connection with such Xenomics Indemnity Claim, or a copy of a court order or judgment together with an opinion of counsel reasonably acceptable to the Escrow Agent to the effect that such order or judgment is a final order or judgment of a court of competent jurisdiction binding on Purchaser and the Shareholders from which no appeal may be taken or for which the time to appeal has expired (a "Final Judgment"), at which time the Escrow Agent shall transfer to the Shareholders the amount of Contingent Shares derived by dividing the amount set forth in such agreement or Final Judgment by $1.25 or such other amount adequately reflecting any stock split, stock exchange, or stock dividend paid or made on or in respect of the Contingent Shares after the Closing Date.

2.5 Xenomics Indemnity Claims Disputed by Purchaser in Part. In the event Purchaser disputes part of, but not all of, a Xenomics Indemnity Claim, the Escrow Agent shall transfer to the Shareholders, that number of Contingent Shares attributable to that portion of the Xenomics Indemnity Claim which is not disputed by Purchaser up to the entire amount of the Contingent Shares. The Escrow Agent shall not transfer any Contingent Shares with respect to the balance of such Xenomics Indemnity Claim except in accordance with the procedures set forth in Section 2.4.

2.6 Notice to Withhold on the Expiration Date. On or prior to the Expiration Date, the Majority Shareholders shall furnish notice (the "Withholding Notice") to the Escrow Agent and Purchaser of the number of Contingent Shares, if any, to be retained on account of Xenomics Indemnity Claims for which an Indemnity Notice but no Determination Notice has been provided pursuant to Section 2.2, or for which an Indemnity Notice and a Determination Notice has been provided pursuant to Section 2.2, but either notice has been disputed by the Purchaser in full or in part pursuant to Section
2.4 (the "Withholding Shares"). The Withholding Notice shall contain the information specified in Section 2.2 to the extent it requires supplementation or change based on the Majority Shareholders' knowledge on the notice date. Upon the receipt by the Escrow Agent of the Withholding Notice, the Escrow Agent shall retain the Withholding Shares. In the event the Majority Shareholders do not timely provide the Withholding Notice, the remaining Contingent Shares shall be distributed by the Escrow Agent to Purchaser in accordance with, and to the extent provided in, Section 2.7.

3

2.7 Distribution of the Escrow Deposit. As soon as practicable following the Expiration Date, any Contingent Shares as shall remain in the Escrow Deposit after deduction of Contingent Shares pursuant to the provisions of Sections 2.3 and 2.5 hereof, and after deduction of Withholding Shares, if any, shall be released from the provisions of this Agreement and distributed promptly by the Escrow Agent to Purchaser.

2.8 Retention of Escrow Deposit After Expiration Date. Upon receipt of the Withholding Notice, the Escrow Agent shall continue to hold after the Expiration Date, the Withholding Shares until such time as the Escrow Agent receives a written agreement signed by the Majority Shareholders and Purchaser stating the number of Contingent Shares, if any, to which the Shareholders are entitled in connection with any outstanding Xenomics Indemnity Claims identified in the Withholding Notice, or a copy of a Final Judgment with respect to such Xenomics Indemnity Claims. As soon as practicable following receipt of such agreement or Final Judgment, the Escrow Agent shall transfer to the Shareholders, with respect to such Xenomics Indemnity Claim, the number of Contingent Shares specified in such agreement or Final Judgment and, unless there are any additional unresolved Xenomics Indemnity Claims that were identified in the Withholding Notice, shall distribute to Purchaser, any remaining Contingent Shares.

2.9 Reservation of the Shareholders' Rights. The rights of the Shareholders to receive disbursements from the Escrow Account in respect of Xenomics Indemnity Claims shall be without prejudice to any other rights the Shareholders may have, under the Exchange Agreement or otherwise, to seek indemnity for Xenomics Indemnity Claims.

2.10 Reporting. The parties hereto shall, for federal income tax purposes and, to the extent permitted by applicable law, state and local tax purposes, report consistent with the Shareholders as the owners of the Contingent Shares and the Shareholders shall furnish any required tax forms consistent with the foregoing.

2.11 Voting and Dispositive Authority. Shareholders shall have no voting and dispositive authority with respect to the Contingent Shares unless and until such Contingent Shares are transferred to Shareholders in accordance with the terms of this Agreement. This paragraph shall be construed as a proxy in favor of the Purchaser acting by vote of a majority of its board of directors to vote (or execute written consents with respect thereto) in favor of proposals recommended by management. This proxy shall be deemed complied with on interest and shall terminate with respect to Contingent Shares upon release.

Section 3 ESCROW AGENT

3.1 Duties. The duties and obligations of the Escrow Agent shall be determined solely by the express provisions of this Agreement and shall be limited to the performance of such duties and obligations as are specifically set forth in this Agreement, as it may be amended from time to time with the Escrow Agent's written consent.

4

3.2 Reliance. In the performance of its duties hereunder, the Escrow Agent shall be entitled to rely upon any document or instrument reasonably believed by it to be genuine and signed by Purchaser or the Shareholders. The Escrow Agent may assume that any person purporting to give any notice in accordance with the provisions hereof has been duly authorized to do so.

3.3 Liability. The Escrow Agent shall not be liable for any error of judgment, or any action taken or omitted to be taken hereunder in good faith, except in the case of its bad faith, gross negligence or willful misconduct. The Escrow Agent shall be entitled to consult with counsel of its choosing (including internal counsel) and shall not be liable for any act suffered or omitted by it in good faith in accordance with the advice of such counsel.

3.4 Disputes. In the event that the Escrow Agent shall be uncertain as to its duties or rights hereunder, or shall receive instructions from any party hereto with respect to the Contingent Shares which, in its opinion, are in conflict with any of the provisions of this Agreement, it shall be entitled to refrain from taking any action until such time as there has been a final determination of the rights of Purchaser and the Shareholders with respect to the Contingent Shares (or relevant portion thereof). For purposes of this
Section 4.4, there shall be deemed to have been a final determination of the rights of Purchaser and the Shareholders with respect to the Contingent Shares (or relevant portion thereof) at such time as Escrow Agent shall receive (i) an executed counterpart of an agreement between the Majority Shareholders and Purchaser or (ii) a copy of a Final Judgment which provides for the disposition of the Contingent Shares (or relevant portion thereof).

3.5 Resignation. The Escrow Agent may resign at any time and be discharged of the duties imposed hereunder (but without prejudice for any liability in the case of its bad faith, gross negligence or willful misconduct hereunder) by giving notice to the Majority Shareholders and Purchaser at least sixty (60) business days prior to the date specified for such resignation to take effect, in which case, upon the effective date of such resignation:

(a) any property then held by the Escrow Agent hereunder shall be delivered by it to such person as may be designated in writing by Purchaser and the Majority Shareholders, whereupon the Escrow Agent's obligations hereunder shall cease and terminate;

(b) if no such person has been designated by such date, all obligations of the Escrow Agent hereunder shall, nevertheless, cease and terminate, subject to clause (c) below; and

(c) the Escrow Agent's sole responsibility thereafter shall be to keep all property then held by it (and to make the investments as hereinbefore provided) and to deliver the same to the successor escrow agent designated in writing by Purchaser and the Majority Shareholders or, if no such successor escrow agent shall have been so designated, in accordance with the directions of a Final Judgment, and the provisions of Section 4.7 and Section 4.8 shall remain in effect.

3.6 Removal of Escrow Agent. Purchaser and the Majority Shareholders may, upon at least thirty (30) business days prior written notice to the Escrow

5

Agent, dismiss the Escrow Agent hereunder and appoint a successor. In such event, the Escrow Agent shall promptly account for and deliver to the successor escrow agent named in such notice the balance of the Escrow Deposit, including all investments thereof and accrued income thereon, on the date of such accounting and delivery. Upon acceptance thereof and of such accounting by such successor escrow agent, and upon reimbursement to the Escrow Agent of all expenses due to it hereunder through the date of such accounting and delivery, the Escrow Agent shall be released and discharged from all of its duties and obligations hereunder, but without prejudice to any liability of the Escrow Agent for its bad faith, gross negligence or willful misconduct hereunder.

3.7 Indemnification. Each of Purchaser and the Shareholders shall jointly indemnify and hold the Escrow Agent harmless against any loss, liability, claim, damage, injury, demand or expense, including reasonable legal fees, arising out of or in connection with the performance of the Escrow Agent's obligations hereunder, including the costs and expenses incurred in connection with the collection of its fees and including the costs and expenses of defending itself against any claim or liability arising out of or in connection with the performance of its duties hereunder, except for any loss, liability, claim, damage, injury, demand or expense resulting from the Escrow Agent's bad faith, gross negligence or willful misconduct; provided, however, that promptly after the receipt by the Escrow Agent of notice of any claim or the commencement of any suit, action or proceeding, the Escrow Agent shall, if a claim of indemnification in respect thereof is to be made against any of the other parties hereto, notify such other parties thereof in writing; and provided, further, that the indemnifying party or parties shall be entitled, jointly or severally and at their own expense, to participate in or assume the defense of any such action, suit or proceeding. The right of the Escrow Agent (or any successor escrow agent appointed hereunder) to indemnification under this
Section 4.7 shall survive the termination of this Agreement.

3.8 Sommer & Schneider LLP.

(a) Each party acknowledges that Sommer & Schneider LLP has acted as legal counsel to and representative of Purchaser and its affiliates in the past and is presently doing so (including, without limitation, in connection with the Exchange Agreement and other related transactions), and agrees that such counsel and representation do not and will not constitute a grounds for disqualifying Sommer & Schneider LLP from acting as Escrow Agent hereunder, and that Sommer & Schneider LLP may continue to so act as legal counsel to and representative to Purchaser and its affiliates in the future in connection with those and all other matters.

(b) Notwithstanding anything to contrary contained herein, it is expressly understood by the parties hereto that the Escrow Agent, in that capacity, at any time that it is required or permitted to seek legal counsel under this Agreement, may seek such legal counsel from Sommer & Schneider LLP, and that the Purchaser and the Shareholders will be jointly liable to Sommer & Schneider LLP for any services performed and billed to the Escrow Agent by Sommer & Schneider LLP at its customary hourly rates and all of Sommer & Schneider LLP's disbursements in connection with the provision of such services.

REPURCHASE AGREEMENT

This Agreement is entered into as of June 24, 2004 by and between Used Kar Parts, Inc., a Florida corporation (the "Company"), and Panetta Partners Ltd., a Colorado limited partnership ("Shareholder").

RECITALS

A. Prior to the date of this Agreement, the Shareholder purchased from the Company 2,000,000 shares of common stock, $.001 par value per share, of the Company (the "Old Common Stock") of which Shareholder owns 1,980,012 shares as of the date hereof.

B. The Company is entering into Purchase Agreements of even date herewith pursuant to which several investors (the "Investors") are purchasing from the Company an aggregate of up to 2,750,000 shares of the Company's common stock (after giving effect to a 111 for 1 stock split, the "New Common Stock") to provide funds for an acquisition of Xenomics, a California corporation.

C. The Investors are willing to purchase shares of New Common Stock and the shareholders of Xenomics are willing to exchange shares of Xenomics for shares of New Common Stock if Shareholder significantly reduces its proportion of ownership in the Company.

AGREEMENTS

In consideration of the foregoing and the other provisions set forth herein, the parties hereby agree as follows:

1. PURCHASE

(a) Subject to the representation and warranties of Shareholder BELOW, the Company hereby agrees to purchase 1,971,734 shares of Old Common Stock (the "Purchased Shares") from the Shareholder for the aggregated price of $500,000 out of the proceeds of the sale of New Common Stock (the "Purchase Price").

(b) The closing of the purchase shall occur simultaneously with the closing of the purchase of New Common Stock by the Investors by delivery of the sum of $500,000 to Purchaser.

(c) This Agreement shall serve as a written instruction of the Shareholder to the company to record the transfer of the Purchased Shares to the Company and, at the Company's option, the cancellation of the Purchased Shares.

1

2. REPRESENTATIONS OF THE SHAREHOLDER

The Shareholder represents and warrants to the Company as of the date of this Agreement and as of the date of the Closing as follows:

(a) Ownership of Stock. Shareholder is the lawful owner of the Purchased Shares free and clear of all preemptive or similar rights, liens, encumbrances, restrictions and claims of every kind. Shareholder has full legal right, power and authority to enter into this Agreement and to sell, assign, transfer and convey the Purchased Shares so owned by such Shareholder pursuant to this Agreement and the delivery to the Company of the Purchased Shares by such Shareholder pursuant to the provisions of this Agreement will transfer to Purchaser valid title thereto, free and clear of all liens, encumbrances, restrictions and claims of every kind.

(b) Authority to Execute and Perform Agreement; No Breach. Shareholder has the full legal right and power and all authority and approval required to enter into, execute and deliver this Agreement, and to sell, assign, transfer and convey the Purchased Shares and to perform fully its obligations hereunder. This Agreement has been duly executed and delivered by such Shareholder and, assuming due execution and delivery by, and enforceability against, the Company, constitutes the valid and binding obligation of Shareholder enforceable in accordance with its terms, subject to the qualifications that enforcement of the rights and remedies created hereby is subject to (i) bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting the rights and remedies of creditors, and (ii) general principles of equity (regardless of whether such enforcement is considered in a proceeding in equity or at law). No approval or consent of, or filing with, any governmental or regulatory body, and no approval or consent of, or filing with, any other person is required to be obtained by Shareholder or in connection with the execution and delivery by Shareholder of this Agreement and consummation and performance by them of the transactions contemplated hereby, other than as set forth on Schedule 1.2. The execution, delivery and performance of this Agreement by Shareholder and the consummation of the transactions contemplated hereby in accordance with the terms and conditions hereof by Shareholder will not:

(i) knowingly violate, conflict with or result in the breach of any of the material terms of, or constitute (or with notice or lapse of time or both would constitute) a material default under, any contract, lease, agreement or other instrument or obligation to which Shareholder is a party or by or to which any of the properties and assets of Shareholder may be bound or subject;

(ii) violate any order, judgment, injunction, award or decree of any court, arbitrator, governmental or regulatory body, by which either Shareholder or the securities, assets, properties or business of Shareholder is bound; or

(iii) knowingly violate any statute, law or regulation.

(c) Restrictive Agreements. Shareholder is not subject to, or a party to, mortgage, lien, lease, license, permit, agreement, contract, instrument, law, rule, ordinance, regulation, order, judgment or decree, or any other

2

restriction of any kind or character, which would prevent consummation of the transactions contemplated by this Agreement, compliance by Shareholder with the terms, conditions and provisions of which would restrict the ability of the Company to acquire any property or conduct its business as conducted or proposed to be conducted.

(d) Broker's or Finder's Fees. No agent, broker, person or firm acting on behalf of the Shareholders is, or will be, entitled to any commission or broker's or finder's fees from any of the parties hereto, or from any person controlling, controlled by or under common control with any of the parties hereto, in connection with any of the transactions contemplated by this Agreement.

XENOMICS, INC.

COMMON STOCK WARRANT

THIS CERTIFIES that, for value received, ____________________________ and its permitted transferees hereunder (the "Holder"), is entitled to subscribe for and purchase from XENOMICS, INC., a Florida corporation (the "Company"), up to ________ fully paid and nonassessable shares (the "Warrant Shares") of common stock, $.0001 par value, of the Company (the "Common Stock") at $1.25 per share (the "Warrant Price") subject to adjustment as provided in Section 2 hereof, at any time or from time to time during the period (the "Exercise Period") commencing on the date hereof and ending on June ___, 2009.

SECTION 1. Exercise of Warrant.

(a) General. This Warrant may be exercised by the Holder as to the whole or any lesser number of the Warrant Shares covered hereby, upon surrender of this Warrant to the Company at its principal executive office together with the Notice of Exercise attached hereto as Exhibit A, duly completed and executed by the Holder, and payment to the Company of the aggregate Exercise Price for the Warrant Shares to be purchased in the form of (i) a check made payable to the Company, (ii) wire transfer according to the Company's instructions or (iii) any combination of (i) and (ii). The exercise of this Warrant shall be deemed to have been effected on the day on which the Holder surrenders this Warrant to the Company and satisfies all of the requirements of this Section 1. Upon such exercise, the Holder will be deemed a shareholder of record of those Warrant Shares for which the warrant has been exercised with all rights of a shareholder (including, without limitation, all voting rights with respect to such Warrant Shares and all rights to receive any dividends with respect to such Warrant Shares). If this Warrant is to be exercised in respect of less than all of the Warrant Shares covered hereby, the Holder shall be entitled to receive a new warrant covering the number of Warrant Shares in respect of which this Warrant shall not have been exercised and for which it remains subject to exercise. Such new warrant shall be in all other respects identical to this Warrant. This Warrant is one of an authorized issue of Warrants to purchase an aggregate of 20,000 share of Common Stock which are of like tenor.

(b) Net Issue Exercise. In lieu of exercising this Warrant via cash payment, the Holder may elect to receive shares equal to the value of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with a Notice of Exercise duly executed and completed indicating payment pursuant to this Section 1(b), in

1

which event the Company shall issue to the Holder a number of shares of Common Stock of the Company computed using the following formula:

X = Y (A - B)

A

Where         X       =    the number of Warrant Shares to be issued to the
                           Holder.

              Y       =    the number of Warrant Shares purchasable under this
                           Warrant or, if only a portion of the Warrant is being
                           exercised, the portion of the Warrant being cancelled
                           (at the date of such calculation).

              A       =    the Fair Market Value (as defined below) of one
                           Warrant Share (at the date of such calculation).

              B       =    the Exercise Price (as adjusted to the date of such
                           calculation).

If the above calculation results in a negative number, then no shares of Common Stock shall be issued or issuable upon conversion of this Warrant.

(c) Fair Market Value. For purposes of this Section 1, the Fair Market Value of one Warrant Share shall be determined by the Company's Board of Directors in good faith; provided, however, that where there exists a public market for the Common Stock at the time of such exercise, the fair market value per Warrant Share shall be the average of the closing bid and asked prices of the Common Stock quoted in the Over-The-Counter Market Summary or the last reported sale price of the Common Stock or the closing price quoted on the Nasdaq National Market or on any exchange on which the Common Stock is listed, whichever is applicable, as published in The Wall Street Journal for the five trading days prior to the date of determination of Fair Market Value.

SECTION 2. Adjustment of Warrant Price.

(a) Except as set forth in Section 2 (b) below, if, at any time during the Exercise Period, the number of outstanding shares of Common Stock is (i) increased by a stock dividend payable in shares of Common Stock or by a subdivision or split of shares of such class of Common Stock, or (ii) decreased by a combination or reverse split of shares of Common Stock, then, following the record date fixed for the determination of holders of Common Stock entitled to receive the benefits of such stock dividend, subdivision, split-up, reverse split-up or combination, the Warrant Price shall be proportionately reduced, in the case of an increase in shares of Common Stock outstanding, or proportionately increased, in the case of a decrease in shares of Common Stock outstanding, in both cases by the ratio which the total number of shares of Common Stock to be outstanding immediately after such event bears to the total number of shares of Common Stock outstanding immediately prior to such event.

(b) This Warrant is issued befor the effective date of a recapitalization of the Company's outstanding stock which will split each

2

outstanding share of common stock, $.001 par value per share, into 111 share of Common Stock, $.0001 par value per share (the "Recapitalization) and represents the right to purchase the number of Warrant Share at the Exercise Price as stated above following such recapitalization. Accordingly, no adjustment will be made under Section 2 (a) above for the Recapitalization.

SECTION 3. Adjustment of Warrant Shares. Upon each adjustment of the Warrant Price as provided in Section 2, the Holder shall thereafter be entitled to subscribe for and purchase, at the Warrant Price resulting from such adjustment, the number of Warrant Shares equal to the product of (i) the number of Warrant Shares existing prior to such adjustment and (ii) the quotient obtained by dividing (A) the Warrant Price existing prior to such adjustment by (B) the new Warrant Price resulting from such adjustment. No fractional shares of capital stock of the Company shall be issued as a result of any such adjustment, and any fractional shares resulting from the computations pursuant to this paragraph shall be eliminated without consideration.

SECTION 4. No Shareholder Rights. This Warrant shall not entitle the holder hereof to any voting rights or other rights as a shareholder of the Company.

SECTION 5. Covenant of the Company. The Company covenants and agrees that the Company shall at all times have authorized and reserved or shall authorize and reserve, free from preemptive rights, a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant.

SECTION 6. Investment Representations and Warranties. The Holder hereby represents and warrants to the Company as follows:

(a) The Holder is acquiring the Warrant, and it will acquire the Common Stock issuable upon exercise thereof, for its own account, for investment and not with a view to the distribution thereof, nor with any present intention of distributing the same. The Holder understands that the Warrant and Common Stock issuable upon exercise thereof, will not be registered under the Act or registered or qualified under any state securities or "blue-sky" laws, by reason of their issuance in a transaction exempt from the registration and/or qualification requirements thereof, and that they must be held indefinitely unless a subsequent disposition thereof is registered under the Act or registered or qualified under any applicable state securities or "blue-sky" laws or is exempt from registration and/or qualification.

(b) The Holder understands that the exemption from registration afforded by Rule 144 (the provisions of which are known to the Holder) promulgated under the Act depends on the satisfaction of various conditions and that, if applicable, Rule 144 may only afford the basis for sales under certain circumstances only in limited amounts.

(c) The Holder has no need for liquidity in its investment in the Company, and is able to bear the economic risk of such investment for an indefinite period and to afford a complete loss thereof.

(d) The Holder is an "accredited purchaser" as such term is defined in Rule 501 (the provisions of which are known to the Holder) promulgated under the Act.

3

SECTION 7. Restrictions on Transfer. The Holder of this Warrant by acceptance hereof agrees that the transfer of this Warrant and the shares of Common Stock issuable upon exercise of this Warrant are subject to the following provisions:

(a) General. Subject to the requirements of the Act or any applicable state securities laws, the Holder may sell, assign, transfer or otherwise dispose of all or any portion of the Warrants or the Warrant Shares acquired upon any exercise hereof at any time and from time to time. Upon the sale, assignment, transfer or other disposition of all or any portion of the Warrants, Holder shall deliver to the Company a written notice of such in the form attached hereto as Exhibit B, duly executed by Holder, which includes the identity and address of any purchaser, assignor or transferee.

(b) Restrictive Legend. Each certificate for Warrant Shares held by the Holder and each certificate for any such securities issued to subsequent transferees of any such certificate shall be stamped or otherwise imprinted with legends in substantially the following form:

"THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT") OR ANY RELEVANT STATE SECURITIES LAWS. THESE SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAWS".

(c) Indemnification. Holder acknowledges that he, she or it understands the meaning and legal consequences of the representations, warranties and acknowledgments he, she or it has made in Section 7 and elsewhere in this Warrant and he, she or it understands that the Company is relying upon the truth and accuracy thereof. Accordingly, the Holder hereby agrees to indemnify and hold harmless the Company, its officers, agents and representatives, from and against any and all loss, damage or liability due to or arising out of a breach of any representation or warranty of Holder contained in this Warrant.

SECTION 8. Amendment. The terms and provisions of this Warrant may not be modified or amended, except with the written consent of the Company and the Holder.

SECTION 9. Reorganizations, Etc. In case, at any time during the Exercise Period, of any capital reorganization, of any reclassification of the stock of the Company (other than a change in par value or from par value to no par value or from no par value to par value or as a result of a stock dividend or subdivision, split-up or combination of shares), or the consolidation or merger of the Company with or into another corporation (other than a consolidation or merger in which the Company is the continuing operation and which does not result in any change or reclassification in the Warrant Shares) or of the sale of all or substantially all the properties and assets of the Company as an entirety to any other corporation, the Company, at its sole discretion, shall have the right and option to (A) provide 10 days prior written notice of such event to the Holder and this Warrant shall terminate and be of no further force and effect on and after the effective date of such capital reorganization or reclassification or the consummation of such consolidation, sale or merger; or (B) provide that this Warrant shall, after such reorganization,

4

reclassification, consolidation, merger or sale, be exercisable for the kind and number of shares of stock or other securities or property of the Company or of the corporation resulting from such consolidation or surviving such merger or to which such properties and assets shall have been sold to which such holder would have been entitled if he, she or it had held the Warrant Shares issuable upon the exercise hereof immediately prior to such reorganization, reclassification, consolidation, merger or sale.

SECTION 10. Lost, Stolen, Mutilated or Destroyed Warrant. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to indemnity or otherwise as it may in its discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as the Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.

SECTION 11. Notices. All notices, advices and communications to be given or otherwise made to any party to this Agreement shall be deemed to be sufficient if contained in a written instrument delivered in person or by telecopier or duly sent by first class registered or certified mail, return receipt requested, postage prepaid, or by overnight courier, or by electronic mail, with a copy thereof to be sent by mail (as aforesaid) within 24 hours of such electronic mail, addressed to such party at the address set forth below or at such other address as may hereafter be designated in writing by the addressee to the addresser listing all parties:

5

determinations and take such other actions with respect to the Plan or any Option as the Board may deem advisable to the extent consistent with the Plan and applicable law.

4. SHARES SUBJECT TO PLAN.

4.1 Maximum Number of Shares Issuable. Subject to adjustment as provided in Section 4.2, the maximum aggregate number of shares of Stock that may be issued under the Plan shall be Five Million (5,000,000) and shall consist of authorized but unissued or reacquired shares of Stock or any combination thereof. If an outstanding Option for any reason expires or is terminated or canceled or if shares of Stock are acquired upon the exercise of an Option subject to a Company repurchase option and are repurchased by the Company at the Optionee's exercise price, the shares of Stock allocable to the unexercised portion of such Option or such repurchased shares of Stock shall again be available for issuance under the Plan.

4.2 Adjustments for Changes in Capital Structure. In the event of any stock dividend, stock split, reverse stock split, recapitalization, combination, reclassification or similar change in the capital structure of the Company, appropriate adjustments shall be made in the number and class of shares subject to the Plan and to any outstanding Options and in the exercise price per share of any outstanding Options. If a majority of the shares which are of the same class as the shares that are subject to outstanding Options are exchanged for, converted into, or otherwise become (whether or not pursuant to an Ownership Change Event, as defined in Section 8.1) shares of another corporation (the "New Shares"), the Board may unilaterally amend the outstanding Options to provide that such Options are exercisable for New Shares. In the event of any such amendment, the number of shares subject to, and the exercise price per share of, the outstanding Options shall be adjusted in a fair and equitable manner as determined by the Board, in its discretion. Notwithstanding the foregoing, any fractional share resulting from an adjustment pursuant to this Section 4.2 shall be rounded down to the nearest whole number, and in no event may the exercise price of any Option be decreased to an amount less than the par value, if any, of the stock subject to the Option. The adjustments determined by the Board pursuant to this Section 4.2 shall be final, binding and conclusive.

5. ELIGIBILITY AND OPTION LIMITATIONS.

5.1 Persons Eligible for Options. Options may be granted only to Employees, Consultants, and Directors. For purposes of the foregoing sentence, "Employees," "Consultants" and "Directors" shall include prospective Employees, prospective Consultants and prospective Directors to whom Options are granted in connection with written offers of employment or other service relationships with the Participating Company Group. Eligible persons may be granted more than one
(1) Option.

5.2 Option Grant Restrictions. Any person who is not an Employee on the effective date of the grant of an Option to such person may be granted only a Nonstatutory Stock Option. An Incentive Stock Option granted to a prospective Employee upon the condition that such person become an Employee shall be deemed granted effective on the date such person commences Service as an employee with a Participating Company, with an exercise price determined as of such date in accordance with Section 6.1.

6

5.3 Fair Market Value Limitation. To the extent that options designated as Incentive Stock Options (granted under all stock option plans of the Participating Company Group, including the Plan) become exercisable by an Optionee for the first time during any calendar year for stock having a Fair Market Value greater than One Hundred Thousand Dollars ($100,000), the portions of such options which exceed such amount shall be treated as Nonstatutory Stock Options. For purposes of this Section 5.3, options designated as Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of stock shall be determined as of the time the option with respect to such stock is granted. If the Code is amended to provide for a different limitation from that set forth in this Section 5.3, such different limitation shall be deemed incorporated herein effective as of the date and with respect to such Options as required or permitted by such amendment to the Code. If an Option is treated as an Incentive Stock Option in part and as a Nonstatutory Stock Option in part by reason of the limitation set forth in this
Section 5.3, the Optionee may designate which portion of such Option the Optionee is exercising. In the absence of such designation, the Optionee shall be deemed to have exercised the Incentive Stock Option portion of the Option first. Separate certificates representing each such portion shall be issued upon the exercise of the Option.

6. TERMS AND CONDITIONS OF OPTIONS.

Options shall be evidenced by Option Agreements, and each Option Agreement shall be either an Option Agreement-Incentive Stock Option or an Option Agreement-Nonstatutory Stock Option. Each Option Agreement shall specify the number of shares of Stock covered thereby, in such form as the Board shall from time to time establish. No Option or purported Option shall be a valid and binding obligation of the Company unless evidenced by a fully executed Option Agreement that is either an Option Agreement-Incentive Stock Option or an Option Agreement-Nonstatutory Stock Option. Option Agreements may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions:

6.1 Exercise Price. The exercise price for each Option shall be established in the discretion of the Board; provided, however, that (a) the exercise price per share for an Incentive Stock Option shall be not less than the Fair Market Value of a share of Stock on the effective date of grant of the Option, (b) the exercise price per share for a Nonstatutory Stock Option shall be not less than eighty-five percent (85%) of the Fair Market Value of a share of Stock on the effective date of grant of the Option, and (c) no Incentive Stock Option granted to a Ten Percent Owner Optionee shall have an exercise price per share less than one hundred ten percent (110%) of the Fair Market Value of a share of Stock on the effective date of grant of the Option. Notwithstanding the foregoing, an Option (whether an Incentive Stock Option or a Nonstatutory Stock Option) may be granted with an exercise price lower than the minimum exercise price set forth above if such Option is granted pursuant to an assumption or substitution for another option in a manner qualifying under the provisions of Section 424(a) of the Code.

6.2 Exercise Period. Options shall be exercisable at such time or times, or upon such event or events, and subject to such terms, conditions, performance criteria, and restrictions as shall be determined by the Board and set forth in the Option Agreement evidencing such Option; provided, however,

7

that (a) no Option shall be exercisable after the expiration of ten (10) years after the effective date of grant of such Option, (b) no Incentive Stock Option granted to a Ten Percent Owner Optionee shall be exercisable after the expiration of five (5) years after the effective date of grant of such Option, and (c) no Option granted to a prospective Employee, prospective Consultant or prospective Director may become exercisable prior to the date on which such person commences Service with a Participating Company. A prospective Director having the contractual right to notice of and be present at Board meetings during such time as he is not a Director shall be deemed to have commenced Service on the day such rights are granted. In addition, excluding any Option granted to an officer, Director or Consultant, no Option shall become exercisable at a rate less than twenty percent (20%) per year over a period of five (5) years from the effective date of grant of such Option, subject to the Optionee's continued Service. Subject to the foregoing, unless otherwise specified by the Board in the grant of an Option, any Option granted hereunder shall have a term of ten (10) years from the effective date of grant of the Option.

6.3 Payment of Exercise Price.

(a) Forms of Consideration Authorized. Except as otherwise provided below, payment of the exercise price for the number of shares of Stock being purchased pursuant to any Option shall be made (i) in cash, by check or cash equivalent, (ii) by tender to the Company, or attestation to the ownership, of shares of Stock owned by the Optionee having a Fair Market Value (as determined by the Company without regard to any restrictions on transferability applicable to such stock by reason of federal or state securities laws or agreements with an underwriter for the Company) not less than the exercise price, (iii) by the assignment of the proceeds of a sale or loan with respect to some or all of the shares being acquired upon the exercise of the Option (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System) (a "Cashless Exercise"), (iv) by the Optionee's promissory note in a form approved by the Company, (v) by such other consideration as may be approved by the Board from time to time to the extent permitted by applicable law, or (vi) by any combination thereof. The Board may at any time or from time to time, by adoption of or by amendment to the standard forms of Option Agreement described in Section 7, or by other means, grant Options which do not permit all of the foregoing forms of consideration to be used in payment of the exercise price or which otherwise restrict one or more forms of consideration, except that consideration described in subparagraph (ii) or (iv) may only be permitted if set forth in the Option Agreement at the time of the grant.

(b) Limitations on Forms of Consideration.

(i) Tender of Stock. Notwithstanding the foregoing, an Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock to the extent such tender or attestation would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company's stock. Unless otherwise provided by the Board at the time of the Option grant, an Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Optionee for more than six (6) months or were not acquired, directly or indirectly, from the Company.

8

(ii) Cashless Exercise. The Company reserves, at any and all times, the right, in the Company's sole and absolute discretion, to establish, decline to approve or terminate any program or procedures for the exercise of Options by means of a Cashless Exercise.

(iii) Payment by Promissory Note. No promissory note shall be permitted if the exercise of an Option using a promissory note would be a violation of any law. Without limiting the generality of the foregoing, no promissory note shall be accepted from any person that is an Insider or if such extension of credit could be a violation of applicable law. Any permitted promissory note shall be on such terms as the Board shall determine at the time the Option is granted. The Board shall have the authority to permit or require the Optionee to secure any promissory note used to exercise an Option with the shares of Stock acquired upon the exercise of the Option or with other collateral acceptable to the Company. Unless otherwise provided by the Board, if the Company at any time is subject to the regulations promulgated by the Board of Governors of the Federal Reserve System or any other governmental entity affecting the extension of credit in connection with the Company's securities, any promissory note shall comply with such applicable regulations, and the Optionee shall pay the unpaid principal and accrued interest, if any, to the extent necessary to comply with such applicable regulations.

6.4 Tax Withholding. The Company shall have the right, but not the obligation, to deduct from the shares of Stock issuable upon the exercise of an Option, or to accept from the Optionee the tender of, a number of whole shares of Stock having a Fair Market Value, as determined by the Company, equal to all or any part of the federal, state, local and foreign taxes, if any, required by law to be withheld by the Participating Company Group with respect to such Option or the shares acquired upon the exercise thereof. Alternatively or in addition, in its discretion, the Company shall have the right to require the Optionee, through payroll withholding, cash payment or otherwise, including by means of a Cashless Exercise, to make adequate provision for any such tax withholding obligations of the Participating Company Group arising in connection with the Option or the shares acquired upon the exercise thereof. The Company shall have no obligation to deliver shares of Stock or to release shares of Stock from an escrow established pursuant to the Option Agreement until the Participating Company Group's tax withholding obligations have been satisfied by the Optionee.

6.5 Repurchase Rights. Shares issued under the Plan may be subject to a right of first refusal, one or more repurchase options, or other conditions and restrictions imposed by the Company's Articles of Incorporation, Bylaws, or as the Board otherwise determines in its discretion at the time the Option is granted. The Company shall have the right to assign at any time any repurchase right it may have, whether or not such right is then exercisable, to one or more persons as the Company may select. Upon request by the Company, each Optionee shall execute any agreement evidencing such transfer restrictions prior to the receipt of shares of Stock hereunder and shall promptly present to the Company any and all certificates representing shares of Stock acquired hereunder for the placement on such certificates of appropriate legends evidencing any such transfer restrictions.

9

6.6 Effect of Termination of Service.

(a) Option Exercisability. Subject to earlier termination of the Option as otherwise provided herein, an Option shall be exercisable after an Optionee's termination of Service as follows:

(i) Disability. If the Optionee's Service with the Participating Company Group is terminated because of the Disability of the Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee's Service terminated, may be exercised by the Optionee (or the Optionee's guardian or legal representative) at any time prior to the expiration of six (6) months (or such longer period of time as determined by the Board, in its discretion) after the date on which the Optionee's Service terminated, but in any event no later than the date of expiration of the Option's term as set forth in the Option Agreement evidencing such Option (the "Option Expiration Date").

(ii) Death. If the Optionee's Service with the Participating Company Group is terminated because of the death of the Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee's Service terminated, may be exercised by the Optionee's legal representative or other person who acquired the right to exercise the Option by reason of the Optionee's death at any time prior to the expiration of six (6) months (or such longer period of time as determined by the Board, in its discretion) after the date on which the Optionee's Service terminated, but in any event no later than the Option Expiration Date. The Optionee's Service shall be deemed to have terminated on account of death if the Optionee dies within thirty (30) days (or such longer period of time as determined by the Board, in its discretion) after the Optionee's termination of Service.

(iii) Other Termination of Service. If the Optionee's Service with the Participating Company Group terminates for any reason, except Disability or death, the Option, to the extent unexercised and exercisable by the Optionee on the date on which the Optionee's Service terminated, may be exercised by the Optionee within thirty (30) days (or such longer period of time as determined by the Board, in its discretion) after the date on which the Optionee's Service terminated, but in any event no later than the Option Expiration Date.

(b) Extension if Exercise Prevented by Law. Notwithstanding the foregoing, if the exercise of an Option within the applicable time periods set forth in Section 6.6(a) is prevented by the provisions of Section 11 below, the Option shall remain exercisable until thirty (30) days (or such longer period of time as determined by the Board, in its discretion) after the date the Optionee is notified by the Company that the Option is exercisable, but in any event no later than the Option Expiration Date.

(c) Extension if Optionee Subject to Section 16(b). Notwithstanding the foregoing, if a sale within the applicable time periods set forth in Section 6.6(a) of shares acquired upon the exercise of the Option would subject the Optionee to suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which a sale of such shares by the Optionee would no longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day after the Optionee's termination of Service, or (iii) the Option Expiration Date.

10

7. STANDARD FORM OF OPTION AGREEMENT.

7.1 General. Unless otherwise provided by the Board at the time the Option is granted, an Option shall comply with and be subject to the terms and conditions set forth in the form of Option Agreement-Incentive Stock Option or Option Agreement-Nonstatutory Stock Option adopted by the Board concurrently with its adoption of the Plan and as amended from time to time.

7.2 Authority to Vary Terms. The Board shall have the authority from time to time to vary the terms of any of the two standard forms of Option Agreement described in this Section 7 either in connection with the grant or amendment of an individual Option or in connection with the authorization of a new standard form or forms; provided, however, that the terms and conditions of any such new, revised or amended two standard form or forms of Option Agreement are not inconsistent with the terms of the Plan.

8. CHANGE IN CONTROL.

8.1 Definitions.

(a) An "Ownership Change Event" shall be deemed to have occurred if any of the following occurs with respect to the Company: (i) the direct or indirect sale or exchange in a single or series of related transactions by the stockholders of the Company of more than fifty percent (50%) of the voting stock of the Company; (ii) a merger or consolidation in which the Company is a party; (iii) the sale, exchange, or transfer of all or substantially all of the assets of the Company; or (iv) a liquidation or dissolution of the Company.

(b) A "Change in Control" shall mean an Ownership Change Event or a series of related Ownership Change Events occurring on or after July 1, 2004 (collectively, a "Transaction") wherein the stockholders of the Company immediately before the Transaction do not retain immediately after the Transaction, in substantially the same proportions as their ownership of shares of the Company's voting stock immediately before the Transaction, direct or indirect beneficial ownership of more than fifty percent (50%) of the total combined voting power of the outstanding voting stock of the Company or the corporation or corporations to which the assets of the Company were transferred (the "Transferee Corporation(s)"), as the case may be. For purposes of the preceding sentence, indirect beneficial ownership shall include, without limitation, an interest resulting from ownership of the voting stock of one or more corporations which, as a result of the Transaction, own the Company or the Transferee Corporation(s), as the case may be, either directly or through one or more subsidiary corporations. The Board shall have the right to determine whether multiple sales or exchanges of the voting stock of the Company or multiple Ownership Change Events are related, and its determination made in good faith shall be final, binding and conclusive.

8.2 Effect of Change in Control on Options. In the event of a Change in Control, the surviving, continuing, successor, or purchasing corporation or parent corporation thereof, as the case may be (the "Acquiring Corporation"), may either assume the Company's rights and obligations under outstanding Options or substitute for outstanding Options substantially

11

equivalent options for the Acquiring Corporation's stock. For purposes of this
Section 8.2, an Option shall be deemed assumed if, following the Change in Control, the Option confers the right to purchase in accordance with its terms and conditions, for each share of Stock subject to the Option immediately prior to the Change in Control, the consideration (whether stock, cash or other securities or property) to which a holder of a share of Stock on the effective date of the Change in Control was entitled. In the event the Acquiring Corporation elects not to assume or substitute for outstanding Options in connection with a Change in Control, any unexercisable or unvested portions of outstanding Options held by Optionees whose Service has not terminated prior to such date shall become immediately exercisable and vested in full (and any unvested share repurchase option shall lapse) as of the date ten (10) days prior to the date of the Change in Control. The accelerated exercise or vesting of any Option that was permissible solely by reason of this Section 8.2 shall be conditioned upon the consummation of the Change in Control. Any Options which are neither assumed or substituted for by the Acquiring Corporation in connection with the Change in Control nor exercised as of the date of the Change in Control shall terminate and cease to be outstanding effective as of the date of the Change in Control. Notwithstanding the foregoing, shares acquired upon exercise of an Option prior to the Change in Control and any consideration received pursuant to the Change in Control with respect to such shares shall continue to be subject to all applicable provisions of the Option Agreement evidencing such Option except as otherwise provided in such Option Agreement. Furthermore, notwithstanding the foregoing, if the corporation the stock of which is subject to the outstanding Options immediately prior to an Ownership Change Event described in Section 8.1(a)(i) constituting a Change in Control is the surviving or continuing corporation and immediately after such Ownership Change Event less than fifty percent (50%) of the total combined voting power of its voting stock is held by another corporation or by other corporations that are members of an affiliated group within the meaning of Section 1504(a) of the Code without regard to the provisions of Section 1504(b) of the Code, the outstanding Options shall not terminate unless the Board otherwise provides in its discretion.

9. PROVISION OF INFORMATION.

At least annually, copies of the Company's balance sheet and income statement for the just completed fiscal year shall be made available to each Optionee and purchaser of shares of Stock upon the exercise of an Option. The Company shall not be required to provide such information to key employees whose duties in connection with the Company assure them access to equivalent information.

10. NONTRANSFERABILITY OF OPTIONS.

Except as otherwise specifically set forth in an Optionee's Option Agreement, no Option shall be assignable or transferable by the Optionee, except by will or by the laws of descent and distribution.

11. COMPLIANCE WITH SECURITIES LAW.

The grant of Options and the issuance of shares of Stock upon exercise of Options shall be subject to compliance with all applicable requirements of federal, state and foreign law with respect to such securities. Options may not be exercised if the issuance of shares of Stock upon exercise would constitute a

12

violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, no Option may be exercised unless (a) a registration statement under the Securities Act shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option or (b) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company's legal counsel to be necessary to the lawful issuance and sale of any shares hereunder shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of any Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company.

12. INDEMNIFICATION.

In addition to such other rights of indemnification as they may have as members of the Board or officers or employees of the Participating Company Group, members of the Board and any officers or employees of the Participating Company Group to whom authority to act for the Board or the Company is delegated shall be indemnified by the Company against all reasonable expenses, including attorneys' fees, actually and necessarily incurred in connection with the defense of any action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or any right granted hereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by independent legal counsel selected by the Company) or paid by them in satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct in duties; provided, however, that within sixty (60) days after the institution of such action, suit or proceeding, such person shall offer to the Company, in writing, the opportunity at its own expense to handle and defend the same.

13. TERMINATION OR AMENDMENT OF PLAN.

The Board may terminate or amend the Plan at any time. However, subject to changes in applicable law, regulations or rules that would permit otherwise, without the approval of the Company's stockholders, there shall be (a) no increase in the maximum aggregate number of shares of Stock that may be issued under the Plan (except by operation of the provisions of Section 4.2), (b) no change in the class of persons eligible to receive Incentive Stock Options, and
(c) no other amendment of the Plan that would require approval of the Company's stockholders under any applicable law, regulation or rule. In any event, no termination or amendment of the Plan may adversely affect any then outstanding Option or any unexercised portion thereof, without the consent of the Optionee, unless such termination or amendment is required to enable an Option designated as an Incentive Stock Option to qualify as an Incentive Stock Option or is necessary to comply with any applicable law, regulation or rule.

13

14. STOCKHOLDER APPROVAL.

The Plan or any increase in the maximum aggregate number of shares of Stock issuable thereunder as provided in Section 4.1 (the "Authorized Shares") shall be approved by the stockholders of the Company within twelve (12) months of the date of adoption thereof by the Board. Options granted prior to stockholder approval of the Plan or in excess of the Authorized Shares previously approved by the stockholders shall become exercisable no earlier than the date of stockholder approval of the Plan or such increase in the Authorized Shares, as the case may be.

3.2 Non-Solicitation. The Executive further agrees that as long as the Agreement remains in effect and, in the event of (a) Voluntary Termination, or (b) termination by Company for Cause, Misconduct or as a result of a Non-Renewal Notice given by the Company or Executive for a period of one

3.3 Remedies.

4. Termination.

4.1 By Company. The Company, acting by duly adopted resolutions of the Board, may, in its discretion and at its option, terminate the Executive's employment with or without Cause or Misconduct, and without prejudice to any other right or remedy to which the Company or Executive may be entitled at law or in equity or under this Agreement. In the event the Company desires to terminate the Executive's employment without Cause or Misconduct, the duly adopted resolutions of the Board must include the consent of at least one director appointed to the Board by the former shareholders of Xenomics, and the Company shall give the Executive not less than sixty (60) days advance written notice of such termination. Termination of Executive's employment hereunder shall be deemed to be "for Cause" in the event that Executive violates his duties under any provisions of this Agreement after there has been delivered to Executive a written demand for performance from the Company which describes the basis for the Company's belief that Executive has not substantially performed his duties. Termination of Executive's employment hereunder shall be deemed to be "for Misconduct", if Executive is found to be in material breach of the provisions of Sections 2 or 3 of this Agreement, is guilty of any felony or an act of fraud or embezzlement, is guilty of willful misconduct or gross neglect, misappropriation, concealment or conversion of any money or property of the Company, or reckless conduct which endangers the safety of other persons or property during the course of employment or while on premises leased or owned by the Company.

4.2 Involuntary Termination. "Involuntary Termination" shall mean (i) the assignment to Executive of any duties or the significant reduction of Executive's duties, either of which is materially inconsistent with Executive's position with the Company and responsibilities in effect immediately prior to such assignment, or the removal of Executive from such position and responsibilities; (ii) a material reduction by the Company in the compensation of Executive, without the Executive's written consent, as in effect immediately prior to such reduction; (iii) a material reduction by the Company in the kind or level of benefits to which Executive is entitled immediately prior to such reduction with the result that Executive's overall benefits package is significantly reduced; (iv) the relocation of Executive to a facility or a location outside the United States on a permanent basis; (v) any termination of Executive by the Company which is not effected for Misconduct, Cause or as a result of a Non-Renewal Notice given by the Company or Executive, or any purported termination for Misconduct or Cause for which the grounds relied upon are determined by a court of competent jurisdiction not to be valid, unless Executive, following such purported termination, receives all compensation, including vesting of all unvested stock options and restricted stock within five business days of such determination, or (vi) the termination by Executive for Company's violation of any material provision of this agreement, unless the grounds relied upon are determined by a court of competent jurisdiction not to be valid.

6

4.3 By Executive's Death or Disability. This Agreement shall also be terminated upon the Executive's death and/or a finding of permanent physical or mental disability, such disability expected to result in death or to be of a continuous duration of no less than three (3) months, and the Executive is unable to perform his usual and essential duties for the Company.

4.4 Voluntary Termination. Executive may voluntarily terminate the Employment Term upon sixty (60) days' prior written notice for any reason; provided, however, that no further payments shall be due under this Agreement in that event except that Executive shall be entitled to any benefits due under any compensation or benefit plan provided by the Company for executives or otherwise outside of this Agreement.

4.5 Compensation on Termination.

(a) Cause or Misconduct. In the event the Company terminates Executive for Cause or Misconduct, Executive shall not be entitled to any compensation other than Base Salary accrued through the date of termination. Such termination shall also immediately cease the vesting of all outstanding unvested options and restricted stock held on the date of termination and all such unvested options shall thereupon expire.

(b) Voluntary Termination. In the event Executive resigns from the Company voluntarily, Executive shall not be entitled to any compensation other than Base Salary accrued through the effective date of his resignation.

(c) Involuntary Termination. In the event Executive is terminated by the Company due to an Involuntary Termination prior to the expiration of the Employment Term, the Company shall pay to Executive (i) the balance of Executive's Base Salary in accordance with the schedule such payments had been made during the six months preceding such termination for the remainder of the Employment Term; and (ii) twenty five percent (25%) of such balance, representing an estimate of all bonuses which would have been paid during such period, payable 60 days after such termination. In addition, the Company shall be obligated, for a period of twenty-four (24) months after any Involuntary Termination, to continue to make available to Executive and to pay for all health, dental, vision, life, dependent life, long-term disability, accidental death and dismemberment and other similar insurance plans existing on the date of Executive's termination, or to provide comparable coverage. The Company shall "gross-up" Executive for any income required to be imputed by virtue of providing the benefits set forth in the preceding sentence, such that the net economic result to Executive will be as if such benefits were provided on a tax-free basis.

(d) Death or Disability. In the event of termination by reason of Executive's death and/or permanent disability, Executive or his executors, legal representatives or administrators, as applicable, shall be entitled to an amount equal to Executive's Base Salary accrued through the date of termination, plus a pro rata share of any annual bonus to which Executive would otherwise be entitled for the year during which death or permanent disability occurs.

2. Confidential Information. Executive recognizes and acknowledges that by reason of Executive's employment by and service to the Company before, during and, if applicable, after the Employment Term, Executive will have access to certain confidential and proprietary information relating to the Company's business, which may include, but is not limited to, trade secrets, trade "know-how," product development techniques and plans, formulas, customer lists and addresses, financing services, funding programs, cost and pricing information, marketing and sales techniques, strategy and programs, computer programs and software and financial information (collectively referred to herein as "Confidential Information"). Executive acknowledges that such Confidential Information is a valuable and unique asset of the Company and Executive covenants that he will not, unless expressly authorized in writing by the Company, at any time during the course of Executive's employment use any Confidential Information or divulge or disclose any Confidential Information to any person, firm or corporation except in connection with the performance of Executive's duties for and on behalf of the Company and in a manner consistent with the Company's policies regarding Confidential Information. Executive also covenants that at any time after the termination of such employment, directly or indirectly, he will not use any Confidential Information or divulge or disclose any Confidential Information to any person, firm or corporation, unless such information is in the public domain through no fault of Executive or except when required to do so by a court of law, by any governmental agency having supervisory authority over the business of the Company or by any administrative or legislative body (including a committee thereof) with apparent jurisdiction to order Executive to divulge, disclose or make accessible such information. All written Confidential Information (including, without limitation, in any computer or other electronic format) which comes into Executive's possession during the course of Executive's employment shall remain the property of the Company. Unless expressly authorized in writing by the Company, Executive shall not remove any written Confidential Information from the Company's premises, except in connection with the performance of Executive's duties for and on behalf of the Company and in a manner consistent with the Company's policies regarding Confidential Information. Upon termination of Executive's employment, the Executive agrees to immediately return to the Company all written Confidential Information (including, without limitation, in any computer or other electronic format) in Executive's possession. As a condition of Executive's continued

4

employment with the Company and in order to protect the Company's interest in such proprietary information, the Company shall require Executive's execution of a Confidentiality Agreement and Inventions Agreement in the form attached hereto as Exhibit "A", and incorporated herein by this reference.

3. Non-Competition; Non-Solicitation.

3.1 Non-Compete. The Executive hereby covenants and agrees that during the term of this Agreement and, in the event of (a) Voluntary Termination (as defined below), or (b) termination by Company for Cause (as defined below) or Misconduct (as defined below), or (c) the expiration of the Employment Term as a result of Executive giving Company a Non-Renewal Notice for a period of one year following the end of the Employment Term, the Executive will not, without the prior written consent of the Company, directly or indirectly, on his own behalf or in the service or on behalf of others, whether or not for compensation, engage in any business activity, or have any interest in any person, firm, corporation or business, through a subsidiary or parent entity or other entity (whether as a shareholder, agent, joint venturer, security holder, trustee, partner, consultant, creditor lending credit or money for the purpose of establishing or operating any such business, partner or otherwise) with any Competing Business in the Covered Area. For the purpose of this Section 3.1, (i) "Competing Business" means any medical or health care company, any contract manufacturer, any research laboratory or other company or entity (whether or not organized for profit) that has, or is seeking to develop, one or more products or therapies that is related to genetic testing through the use of urine specimens and (ii) "Covered Area" means all geographical areas of the United States, Italy and other foreign jurisdictions where Company then has offices and/or sells its products directly or indirectly through distributors and/or other sales agents.

3.2 Non-Solicitation. The Executive further agrees that as long as the Agreement remains in effect and, in the event of (a) Voluntary Termination, or (b) termination by Company for Cause, Misconduct or as a result of a Non-Renewal Notice given by the Company or Executive for a period of one
(1) year from its termination, the Executive will not divert any business of the Company and/or its affiliates or any customers or suppliers of the Company and/or the Company's and/or its affiliates' business to any other person, entity or competitor, or induce or attempt to induce, directly or indirectly, any person to leave his or her employment with the Company and/or its affiliates.

3.3 Remedies. The Executive acknowledges and agrees that his obligations provided herein are necessary and reasonable in order to protect the Company and its affiliates and their respective business and the Executive expressly agrees that monetary damages would be inadequate to compensate the Company and/or its affiliates for any breach by the Executive of his covenants and agreements set forth herein. Accordingly, the Executive agrees and acknowledges that any such violation or threatened violation of this Section 3 will cause irreparable injury to the Company and that, in addition to any other remedies that may be available, in law, in equity or otherwise, the Company and

5

its affiliates shall be entitled to obtain injunctive relief against the threatened breach of this Section 3 or the continuation of any such breach by the Executive without the necessity of proving actual damages.

4. Termination.

The Company, acting by duly adopted resolutions of the Board, may, in its discretion and at its option, terminate the Executive's employment with or without Cause or Misconduct, and without prejudice to any other right or remedy to which the Company or Executive may be entitled at law or in equity or under this Agreement. In the event the Company desires to terminate the Executive's employment without Cause or Misconduct, the duly adopted resolutions of the Board must include the consent of at least one director appointed to the Board by the former shareholders of Xenomics, and the Company shall give the Executive not less than sixty (60) days advance written notice of such termination. Termination of Executive's employment hereunder shall be deemed to be "for Cause" in the event that Executive violates his duties under any provisions of this Agreement after there has been delivered to Executive a written demand for performance from the Company which describes the basis for the Company's belief that Executive has not substantially performed his duties. Termination of Executive's employment hereunder shall be deemed to be "for Misconduct", if Executive is found to be in material breach of the provisions of Sections 2 or 3 of this Agreement, is guilty of any felony or an act of fraud or embezzlement, is guilty of willful misconduct or gross neglect, misappropriation, concealment or conversion of any money or property of the Company, or reckless conduct which endangers the safety of other persons or property during the course of employment or while on premises leased or owned by the Company.

4.2 Involuntary Termination. "Involuntary Termination" shall mean (i) the assignment to Executive of any duties or the significant reduction of Executive's duties, either of which is materially inconsistent with Executive's position with the Company and responsibilities in effect immediately prior to such assignment, or the removal of Executive from such position and responsibilities; (ii) a material reduction by the Company in the compensation of Executive, without the Executive's written consent, as in effect immediately prior to such reduction; (iii) a material reduction by the Company in the kind or level of benefits to which Executive is entitled immediately prior to such reduction with the result that Executive's overall benefits package is significantly reduced; (iv) the relocation of Executive to a facility or a location outside the United States on a permanent basis; (v) any termination of Executive by the Company which is not effected for Misconduct, Cause or as a result of a Non Renewal Notice given by the Company or Executive, or any purported termination for Misconduct or Cause for which the grounds relied upon are determined by a court of competent jurisdiction not to be valid, unless Executive, following such purported termination, receives all compensation, including vesting of all unvested stock options and restricted stock within five business days of such determination, or (vi) the termination by Executive for Company's or Holding's violation of any material provision of this agreement, unless the grounds relied upon are determined by a court of competent jurisdiction not to be valid.

4.3 By Executive's Death or Disability. This Agreement shall also be terminated upon the Executive's death and/or a finding of permanent

6

physical or mental disability, such disability expected to result in death or to be of a continuous duration of no less than three (3) months, and the Executive is unable to perform his usual and essential duties for the Company.

4.4 Voluntary Termination. Executive may voluntarily terminate the Employment Term upon sixty (60) days' prior written notice for any reason; provided, however, that no further payments shall be due under this Agreement in that event except that Executive shall be entitled to any benefits due under any compensation or benefit plan provided by the Company for executives or otherwise outside of this Agreement.

4.5 Compensation on Termination.

(a) Cause or Misconduct. In the event the Company terminates Executive for Cause or Misconduct, Executive shall not be entitled to any compensation other than Base Salary accrued through the date of termination. Such termination shall also immediately cease the vesting of all outstanding unvested options and restricted stock held on the date of termination and all such unvested options shall thereupon expire.

The term of this Agreement shall commence as of June 24, 2004 (the "Effective Date") and shall continue for 36 months, unless earlier terminated in accordance with Section 4 hereof. The term shall be automatically renewed for successive one (1) year periods until the Consultant or the Company delivers to the other party a written notice of their intent not to renew the "Consulting Term," (a "Non-Renewal Notice") such written notice to be delivered at least sixty (60) days prior to the expiration of the then-effective "Consulting Term" as that term is defined below. The period commencing as of the Effective Date and ending 36 months thereafter or such later date (the "Expiration Date") to which the term of this Agreement shall have been extended by mutual written agreement is referred to herein as the "Consulting Term."

1.7 No Other Compensation. Except as expressly provided in Sections 1.4 through 1.6, and under Section 4 below, Consultant shall not be entitled to any other compensation or benefits for services to the Company in any capacity and for services as an officer, director, employee and consultant for Company's subsidiaries, affiliates and joint ventures.

2. Confidential Information. Consultant recognizes and acknowledges that by reason of Consultant's engagement by and service to the Company before, during and, if applicable, after the Consulting Term, Consultant will have access to certain confidential and proprietary information relating to the Company's business, which may include, but is not limited to, trade secrets, trade "know-how," product development techniques and plans, formulas, customer lists and addresses, financing services, funding programs, cost and pricing information, marketing and sales techniques, strategy and programs, computer programs and software and financial information (collectively referred to herein as "Confidential Information").

Consultant also covenants that at any time after the termination of such engagement, directly or indirectly, he will not use any Confidential Information or divulge or disclose any Confidential Information to any person, firm or corporation, unless such information is in the public domain through no fault of Consultant or except when required to do so by a court of law, by any governmental agency having supervisory authority over the business of the Company or by any administrative or legislative body (including a committee thereof) with apparent jurisdiction to order Consultant to divulge, disclose or make accessible such information. All written Confidential Information (including, without limitation, in any computer or other electronic format) which comes into Consultant's possession during the course of Consultant's engagement shall remain the property of the Company. Unless expressly authorized in writing by the Company, Consultant shall not remove any written Confidential Information from the Company's premises, except in connection with the performance of Consultant's duties for and on behalf of the Company and in a manner consistent with the Company's policies regarding Confidential Information. Upon termination of Consultant's engagement, the Consultant agrees to immediately return to the Company all written Confidential Information (including, without limitation, in any computer or other electronic format) in Consultant's possession. As a condition of Consultant's continued engagement with the Company and in order to protect the Company's interest in such proprietary information, the Company shall require Consultant's execution of a Confidentiality Agreement and Inventions Agreement in the form attached hereto as Exhibit "A", and incorporated herein by this reference.

4.2 Involuntary Termination. "Involuntary Termination" shall mean (i) a material reduction by the Company in the compensation of Consultant, without the Consultant's written consent, as in effect immediately prior to such reduction; (ii) any termination of Consultant by the Company which is not effected for Misconduct, Cause or as a result of the expiration of the Term as a result of a Non-Renewal Notice, or any purported termination for Misconduct or Cause for which the grounds relied upon are determined by a court of competent jurisdiction not to be valid, unless Consultant, following such purported termination, receives all compensation, including vesting of all unvested stock options and restricted stock within five business days of such determination, or
(iii) the termination by Consultant for Company's or Holding's violation of any material provision of this agreement, unless the grounds relied upon are determined by a court of competent jurisdiction not to be valid.

4.3 By Consultant's Death or Disability. This Agreement shall also be terminated upon the Consultant's death and/or a finding of permanent physical or mental disability, such disability expected to result in death or to be of a continuous duration of no less than three (3) months, and the Consultant is unable to perform his usual and essential duties for the Company.

4.4 Voluntary Termination. Consultant may voluntarily terminate the Engagement Term upon sixty (60) days' prior written notice for any reason; provided, however, that no further payments shall be due under this Agreement in that event except that Consultant shall be entitled to any benefits due under any compensation or benefit plan provided by the Company for Consultants or otherwise outside of this Agreement.

1. Agreement to Vote.

1.1 Voting of Shares.During the term of this Voting Agreement, the Original Shareholders and the Investors agree to vote all of the shares of


the Company's common stock now or hereafter owned by them, whether beneficially or otherwise (collectively, hereinafter referred to as the "Voting Shares"), at any regular or special meeting of shareholders of the Company, or, in lieu of any such meeting, to give their written consent, or to vote their respective Voting Shares in any other manner permitted by applicable law in the election or removal of directors of the Company as provided in this Voting Agreement.

1.2 Designation of Xenomics Directors. The Original Shareholders and the Investors hereby agree that, as long the Xenomics Shareholders own the aggregate of 752,667 shares of the Company's capital stock, a majority-in-interest of the Xenomics Shareholders shall have the right (a) (i) if the number of directors then constituting the entire Company's Board of Directors (the "Board") is more than 7, to designate one-third (1/3), of the members of the Board (each, a "Xenomics Director," and, collectively, the "Xenomics Directors"), it being understood that, in the event the number of directors constituting the Board is not dividable by the number three (3), that Xenomics shall have the right to designate the number of Xenomics Directors that equals one-third (1/3) of the next lower number that is dividable by three (3),
(ii) if the number of directors constituting the entire board is between 5 and 7, to designate 2 Xenomics Directors, and (iii) if the number of directors constituting the entire board is less than 5, one (1) Xenomics Director and 1 non-voting Board observer, who shall have equal rights to receive notices of and attend meetings of the Board ("Xenomics Observer"); (b) to remove any Xenomics Director or Xenomics Observer with or without cause and to designate one new Xenomics Director in any removed Xenomics Director's place, and one new Xenomics Observer in any removed Xenomics Observer's place; and (c) to appoint a replacement in the event a Xenomics Director or Observer resigns. The members of the Board, as of the effective date of this Agreement, are: L.

1.3 Additional Board Observer. For so long as Gabe Cerrone (a) is not a member of the Board, and (b) holds shares of the Company's voting stock, he shall have the right to be a non-voting observer, who shall have the same right as a Board member to receive notices of and attend Board meetings.

1.4 Vote for Xenomics Director. The Original Shareholders and the Investors hereby agree to vote that number of Voting Shares as to which they have beneficial ownership sufficient to appoint, elect, remove, or replace, as the case may be, any Xenomics Director to or from the Board as may be directed by a majority-in-interest of the Xenomics Shareholders in accordance with
Section 2.2 above.

2. Grant of Proxy. Should the provisions of this Voting Agreement be construed to constitute the granting of proxies, such proxies shall be deemed coupled with an interest and, to the extend permitted by law, are irrevocable for the term of this Voting Agreement.

(c) The selection and approval of a treasurer of the Company, and its chief financial and chief accounting officers shall be made by the Board by an affirmative vote of not less than the majority of the entire Board.

4. Specific Enforcement.
