(3) Sufficient Shares Reserved.

The Company shall initially reserve at least 100% of the number of shares of Common Stock issuable to Holder as of the Closing Date. The Company shall take all actions necessary to give effect to the preceding sentence, including, without limitation, amending its Certificate of Incorporation to authorize additional shares of Common Stock, if necessary. (4) Conversion Procedures. (a) Conversion shall be effectuated by surrendering this Debenture to the Company (if such Conversion will convert all outstanding principal) together with the form of conversion notice attached hereto as Exhibit A (the "Notice of Conversion"), executed by the Holder of this Debenture evidencing such Holder's intention to convert this Debenture or a specified portion (as above provided) hereof, and accompanied, if required by the Company, by proper assignment hereof in blank. Interest accrued or accruing from the date of issuance to the date of conversion shall be paid in cash or shares of Common Stock as set forth above. No fraction of a share or scrip representing a fraction of a share will be issued on conversion, but the number of shares issuable shall be rounded up to the nearest whole share. The date on which Notice of Conversion is given (the "Conversion Date") shall be deemed to be the date on which the Holder faxes the Notice of Conversion duly executed to the Company. Facsimile delivery of the Notice of Conversion shall be accepted by the Company at facsimile number +44 (0) 1463 667 310, Attn.: Martin Thorp, Chief Financial Officer.

This Debenture is a direct obligation of the Company. (6) Debenture Secured by Subordinated Security Interest. Longview has and shall continue to have valid, enforceable and perfected second-priority lien upon and security interests in the Pledged Property (as defined in the Transaction Documents) heretofore granted. All payments due under this Note shall be subordinated and made junior, in all respects to the payment in full of all principal, all interest accrued thereon and all other amounts due on the secured indebtedness of the Company set forth in Schedule I of this Debenture. (7) Merger; Consolidation; Sale of Assets. If the Company merges or consolidates with another corporation or sells or transfers all or substantially all of its assets to another person and the holders of the Common Stock are entitled to receive stock, securities or property in respect of or in exchange for Common Stock, then as a condition of such merger, consolidation, sale or transfer, the Company and any such successor, purchaser or transferee agree that the Debenture may thereafter be converted on the terms and subject to the conditions set forth above into the kind and amount of stock, securities or property receivable upon such merger, consolidation, sale or transfer by a holder of the number of shares of Common Stock into which this Debenture might have been converted immediately before such merger, consolidation, sale or transfer, subject to adjustments which shall be as nearly equivalent as may be practicable. In the event of any proposed merger, consolidation or sale or transfer of all or substantially all of the assets of the Company (a "Sale"), the Holder hereof shall have the right to convert any or all of the Debenture by delivering a Notice of Conversion to the Company within ten (10) days of receipt of notice of such Sale from the Company, which notice the Company shall be required to give.

Upon the occurrence of an Event of Default, or at any time thereafter, and in each and every such case, unless such Event of Default shall have been waived in writing by the Holder (which waiver shall not be deemed to be a waiver of any subsequent default) at the option of the Holder and in the Holder's sole discretion, the Holder may consider this Debenture immediately due and payable, without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived, anything herein or in any note or other instruments contained to the contrary notwithstanding, and the Holder may immediately enforce any and all of the Holder's rights and remedies provided herein or any other rights or remedies afforded by law; provided, that any payment of this Debenture in connection with an Event of Default may, at the option of the Holder, be made in shares of Common Stock of the Company which number of shares shall be calculated based upon at the lesser of the closing sale price of the Common Stock on the date the Debenture becomes due and payable or $0.05. Such payment of shares shall be made within twenty (20) Trading Days of such demand. (10) No Rights as Stockholder. Nothing contained in this Debenture shall be construed as conferring upon the Holder the right to vote or to receive dividends or to consent or receive notice as a stockholder in respect of any meeting of stockholders or any rights whatsoever as a stockholder of the Company, unless and to the extent converted in accordance with the terms hereof. (11) Additional Conversion Restriction. In no event shall any holder be entitled to convert the outstanding principal amount and accrued interest of this Debenture for shares of Common Stock in excess of that number of shares of Common Stock that, upon giving effect to such conversion, would cause the aggregate number of shares of Common Stock beneficially owned by the holder and its "affiliates" (as defined in Rule 405 under the Securities Act) to exceed 4.99% of the outstanding shares of the Common Stock of the Company following such conversion. For purposes of this Section 14, the aggregate number of shares of Common Stock beneficially owned by the Holder and its affiliates shall include the number of shares of Common Stock issuable upon conversion of the Debenture with respect to which the determination is being made, but shall exclude the number of shares of Common Stock that would be issuable upon (i) conversion of any remaining, unconverted portion of this Debenture and (ii) exercise or conversion of the unexercised or unconverted portion of any other Securities (including, without limitation, any warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder and its affiliates. Except as set forth in the preceding sentence, for purposes of this Section 14, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended. For purposes of this Section 14, in determining the number of outstanding shares of Common Stock a Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company's most recent Form 10-QSB or Form 10-KSB, as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or its transfer agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request of any holder, the Company shall immediately confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to conversions of portions of the Debenture by such Holder since the date as of which such number of outstanding shares of Common Stock was reported. To the extent that the limitation contained in this Section 14 applies, the determination of whether the Debenture is convertible (in relation to other securities owned by a Holder) and of which portion of this Debenture is convertible shall be in the sole discretion of the Holder, and the submission of a Notice of Conversion shall be deemed to be the Holder's determination that the Debenture is convertible, in each case subject to such aggregate percentage limitation, and the Company shall have no obligation or right to verify or confirm the accuracy of such determination. Nothing contained herein shall be deemed to restrict the right of a holder to convert the Debenture at such time as such conversion will not violate the provisions of this Section 14. IN WITNESS WHEREOF, the Company has caused this instrument to be executed by its officer thereunto duly authorized as of the day and year first above written. IN VERITAS MEDICAL DIAGNOSTICS, INC.
