The Assignor acknowledges in favour of a third party that a certificate in writing signed by the Assignee or any person appointed in accordance with Clause 7.5 that any instrument or act falls within the authority conferred by this Agreement shall be conclusive evidence that such is the case. 7.4 This power of attorney is irrevocable as long as the Assignor's obligations under this agreement remain undischarged. 7.5 Without prejudice to Clause 7.2, the attorney may, in any way it thinks fit and in the name and on behalf of the Assignor: (a) take any action that this Agreement requires the Assignor to take; (b) exercise any rights which this Agreement gives to the Assignor; and (c) appoint and remove one or more substitute attorneys with full power as the Assignor's attorney on terms that the attorney thinks fit. 7.6 The Assignor must ratify and confirm everything that the attorney and any substitute attorney does or arranges using the powers granted under this clause. 7.7 The Assignor shall without delay communicate and deliver up to the Assignee all available information and materials relating to all Inventions, Patents and Improvements. 7.8 The Assignor shall give notice in writing to the Assignee promptly on becoming aware of any infringement or suspected infringement of any Patent. 7.9 The Assignor shall not do or allow to be done anything which would or might prejudice the rights of the Assignee under this Agreement. 8.

RE-ASSIGNMENT 9.1 Notwithstanding anything to the contrary under this Agreement, it is agreed that if, at any time prior to the execution of the Warrant, the Assignee: (i) ceases to do business; (ii) becomes unable to pay its debts as they fall due; (iii) becomes or is deemed insolvent; (iv) has a receiver, liquidator, manager, administrator or similar officer appointed in respect of the whole or any part of its assets or business (or is the subject of a filing with any court for the appointment of any such officer); (v) makes any composition or arrangement with its creditors; or (vi) any equivalent or similar action or proceeding is taken or suffered in any jurisdiction, and the same is not dismissed or discharged within 30 days, the Assignor may demand, by a written notice to the Assignee, to revoke the assignment and transfer of the Patents and Inventions taken in accordance with this Agreement, as follows: (a) the Assignee shall vest, transfer and assign back to the Assignor all the rights, titles and interests in and to the Patents and Inventions, that were assigned or transferred to it in accordance with this Agreement; (b) the Assignor shall return to the Assignee any and all payments it has received in accordance with this Agreement, plus interest at a rate of 5% per annum, compounded daily, from the date it has received such payment until the date such payment is returned in accordance with this Clause; and (c) the Assignor shall return to the Assignee the warrant it has received under Clause 4.3. 6 9.2 the Parties shall, at the Assignor expense, perform all further acts and things, and sign, execute and deliver of all further deeds, declarations and documents, as may be required for such re-assignment. 10. VARIATION An amendment or a variation of this Agreement shall be valid only if it is made in writing and signed by all Parties. 11. REMEDIES 11.1 The failure to exercise or delay in exercising a right or remedy provided by this Agreement or by law does not constitute a waiver of the right or remedy or a waiver of other rights or remedies. No single or partial exercise of a right or remedy provided by this Agreement or by law prevents further exercise of the right or remedy or the exercise of another right or remedy. 11.2 Each Party's rights and remedies contained in this Agreement are cumulative and not exclusive of rights or remedies provided by law. 12. SEVERABILITY If, at any time, any provision of this Agreement is or becomes illegal, invalid or unenforceable in any respect under any law of any jurisdiction, neither the legality, validity or enforceability of the remaining provisions nor the legality, validity or enforceability of such provision in any other respect or under the law of any other jurisdiction will in any way be affected or impaired. 13. ENTIRE AGREEMENT This Agreement constitutes the entire agreement and understanding between the Parties and supersedes all other agreements both oral and in writing between them in respect to its subject matter. 14. ASSIGNMENT Otherwise as expressly provided herein, a Party shall not be entitled to assign any of its rights and obligations under this Agreement without the prior written approval of the other Parties. 15. NO PARTNERSHIP OR AGENCY Nothing in this Agreement is intended to, or shall be deemed to, constitute a partnership or joint venture of any kind between any of the Parties, not constitute any Party the agent of another party for any purpose, nor constitute an employer-employee relationship between the Parties. 16.

PAYMENT OF EXERCISE PRICE. Payment of the Exercise Price shall be made by check made payable to the order of the Company or by wire transfer of immediately available funds to a bank account designated by the Company [in available funds in U.S. Dollars]. 4. ADJUSTMENT FOR DIVIDENDS, DISTRIBUTIONS, SUBDIVISIONS, COMBINATIONS, MERGERS, CONSOLIDATIONS OR SALE OF ASSETS 4.1 Manner of Adjustment. (a) Stock Dividends, Distributions or Subdivisions. In the event the Company shall issue shares of Common Stock in a stock dividend, stock distribution or subdivision, the Exercise Price in effect immediately before such stock dividend, stock distribution or subdivision shall, concurrently with the effectiveness of such stock dividend, stock distribution or subdivision, be proportionately decreased and the number of shares of Common Stock purchasable by exercise of this Warrant shall be proportionately increased. (b) Combinations or Consolidations. In the event the outstanding shares of Common Stock shall be combined or consolidated, by reclassification or otherwise, into a lesser number of shares of Common Stock, the Exercise Price in effect immediately prior to such combination or consolidation shall, concurrently with the effectiveness of such combination or consolidation, be proportionately increased and the number of shares of Common Stock purchasable by exercise of this Warrant shall be proportionately decreased. (c) Adjustment for Reclassification, Exchange or Substitution. In the event that the class of securities issuable upon the exercise of this Warrant shall be changed into the same or a different number of shares of any class or classes of stock, whether by capital reorganization, reclassification or otherwise (other than any event addressed by Sections 4.1(a), 4.1(b) or 4.1(d)), then and in each such event the Holder shall have the right thereafter to exercise this Warrant for the kind and amount of shares of stock and other securities and property receivable upon such reorganization, reclassification, or other change, by holders of the number of shares of the class of securities into which such Warrant might have been exercisable for immediately prior to such reorganization, reclassification, or change, all subject to further adjustment as provided herein. (d) Adjustment for Merger, Consolidation or Sale of Assets. In the event that the Company shall merge or consolidate with or into another entity or sell all of its assets, this Warrant shall thereafter be exercisable for the kind and amount of shares of stock or other securities or property to which a holder of the number of shares of Common Stock of the Company deliverable upon exercise of this Warrant would have been entitled upon such consolidation, merger or sale; and, in such case, appropriate adjustment (as determined in good faith by the Company's Board of Directors) shall be made in the application of the provisions set forth in this Section 4 with respect to the rights and interest thereafter of the Holder of this Warrant, to the end that the provisions set forth in this Section 4 shall thereafter be applicable, as nearly as reasonably may be, in relation to any shares of stock or other property thereafter deliverable upon the exercise of this Warrant. 4.2 Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Exercise Price pursuant to this Section 4, the Company at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to the Holder a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. 11 4.3 Closing of Books. The Company shall at no time close its transfer books against the transfer of any shares of Common Stock issued or issuable upon the exercise of this Warrant in any manner which interferes with the timely and proper issuance of such shares. 5. COVENANTS OF THE COMPANY. During the period within which the rights represented by this Warrant may be exercised, the Company shall at all times have authorized and reserved for the purpose of issue upon exercise of the rights evidenced hereby, a sufficient number of shares of the class of securities issuable upon exercise of this Warrant to provide for the exercise of such rights. All securities which may be issued upon the exercise of the rights represented by this Warrant shall, upon issuance, be duly authorized, validly issued, fully paid and non-assessable and free from all taxes, liens and charges with respect to the issue thereof. Upon surrender for exercise, this Warrant shall be canceled and shall not be reissued; provided, however, that upon the partial exercise hereof a substitute Warrant of like tenor and date representing the rights to subscribe for and purchase any such unexercised portion hereof shall be issued. 6. NO RIGHTS AS SHAREHOLDER UNTIL EXERCISE. This Warrant shall not entitle the Holder to any voting rights or any other rights as a stockholder of the Company but upon presentation of this Warrant with the Exercise Notice duly executed and the tender of payment of the Exercise Price at the office of the Company pursuant to the provisions of this Warrant, the Holder shall forthwith be deemed a stockholder of the Company in respect of the securities for which the Holder has so subscribed and paid. 7. NO CHANGE NECESSARY. The form of this Warrant need not be changed because of any adjustment in the Exercise Price or in the number of shares issuable upon its exercise. A Warrant issued after any adjustment or any partial exercise or upon replacement may continue to express the same Exercise Price and the same number of shares (appropriately reduced in the case of partial exercise) as are stated on this Warrant as initially issued, and that Exercise Price and that number of shares shall be considered to have been so changed as of the close of business on the date of adjustment. 8.

TRANSFER RESTRICTIONS. This Warrant shall not be transferable by the Holder and shall be exercisable only by the Holder. Without the prior written consent of the Company, the Warrant shall not be assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process. Any attempted transfer, assignment, pledge, hypothecation or other disposition of the Warrant or of any 12 rights granted hereunder contrary to the provisions of this Section 10, or the levy of any attachment or similar process upon the Warrant or such rights, shall be null and void. 11. TAXES.

REMEDIES. Each party stipulates that the remedies at law in the event of any default or threatened default by the other party in the performance or compliance with any of the terms of this Warrant may not be adequate, and that such terms may be specifically enforced by a decree for that specific performance of any agreement contained herein or by an injunction against a violation of any of the terms hereof or otherwise. 13. GOVERNING LAW. This Warrant shall be construed and enforced in accordance with, and governed by, the laws of the State of Nevada without regard to its principles of conflicts of laws. 14.
