4.2              Adjustment for Other Dividends and Distributions.  In case the Company shall make or issue, or shall fix a record date for the determination of eligible holders entitled to receive, a dividend or other distribution payable with respect to the Warrant Stock that is payable in (a) securities of the Company (other than issuances with respect to which adjustment is made under Section 4.1), or (b) assets (other than cash dividends paid or payable solely out of retained earnings), then, and in each such case, the Holder, upon exercise of this Warrant at any time after the consummation, effective date or record date of such event, shall receive, in addition to the shares of Warrant Stock issuable upon such exercise prior to such date, the securities or such other assets of the Company to which the Holder would have been entitled upon such date if the Holder had exercised this Warrant immediately prior thereto (all subject to further adjustment as provided in this Warrant).

4.3              Adjustment for Reorganization, Consolidation, Merger.  In case of any reorganization of the Company (or of any other corporation or entity, the stock or other securities of which are at the time receivable on the exercise of this Warrant), after the date of this Warrant, or in case, after such date, the Company (or any such corporation or entity) shall consolidate with or merge into another corporation or entity or convey all or substantially all of its assets to another corporation or entity, then, and in each such case, the Holder, upon the exercise of this Warrant (as provided in Section 2), at any time after the consummation of such reorganization, consolidation, merger or conveyance, shall be entitled to receive, in lieu of the stock or other securities and property receivable upon the exercise of this Warrant prior to such consummation, the stock or other securities or property to which the Holder would have been entitled upon the consummation of such reorganization, consolidation, merger or conveyance if the Holder had exercised this Warrant immediately prior thereto, all subject to further adjustment as provided in this Warrant, and the successor or purchasing corporation or entity in such reorganization, consolidation, merger or conveyance (if other than the Company) shall duly execute and deliver to the Holder a supplement hereto acknowledging such corporation's or entity's obligations under this Warrant; and in each such case, the terms of this Warrant shall be applicable to the shares of stock or other securities or property receivable upon the exercise of this Warrant after the consummation of such reorganization, consolidation, merger or conveyance.

4.4              [Intentionally Deleted]

4.5              Notice of Certain Events and Adjustments.  The Company shall give thirty days prior written notice of the record date fixed for any Acquisition, Asset Transfer or event  referred to in Section 4.2 or 4.3.  The Company shall promptly give written notice of each adjustment or readjustment of the Warrant Price or the number of shares of Warrant Stock or other securities issuable upon exercise of this Warrant.  The notice shall describe the adjustment or readjustment and show in reasonable detail the facts on which the adjustment or readjustment is based.

4.6              No Change Necessary.  The form of this Warrant need not be changed because of any adjustment in the Warrant Price or in the number of shares of Warrant Stock issuable upon its exercise.

5.                  No Rights or Liabilities as Stockholder.  This Warrant does not by itself entitle the Holder to any voting rights or other rights as a stockholder of the Company.  In the absence of affirmative action by the Holder to purchase Warrant Stock by exercise of this Warrant, no provisions of this Warrant, and no enumeration herein of the rights or privileges of the Holder, shall cause the Holder to be a stockholder of the Company for any purpose.

6.                  Attorneys' Fees.  The Company shall pay the reasonable attorneys' fees, costs and disbursements of the Holder in enforcing any terms of this Warrant, whether or not any action at law or in equity is brought.

7.                  Transfer.  This Warrant may be transferred or assigned by the Holder hereof in whole or in part, if, on the Company's reasonable request, the Holder provides an opinion of counsel reasonably satisfactory to the Company that such transfer does not require registration under the Act and the applicable state securities law, except that this Warrant may be transferred by a Holder which is a partnership or limited liability company to a partner, former partner, member, former member or other affiliate of such partnership or limited liability company, as the case may be, if (a) the transferee agrees in writing to be subject to the terms of this Warrant and (b) the Holder delivers notice of such transfer to the Company.  The rights and obligations of the Company and the Holder under this Warrant shall be binding upon and inure to the benefit of their respective permitted successors, assigns, heirs, administrators and transferees.

8.                  Loss or Mutilation.  Upon receipt by the Company of evidence reasonably satisfactory to it of the ownership and the loss, theft, destruction or mutilation of this Warrant, and of indemnity reasonably satisfactory to it, and (in the case of mutilation) upon surrender and cancellation of this Warrant, the Company will execute and deliver in lieu thereof a new Warrant of like tenor.

9.                  Reservation of Warrant Stock.  If at any time the number of authorized but unissued shares of the Warrant Stock shall not be sufficient to effect the exercise of this Warrant, the Company shall take all such corporate action as may be necessary to increase its authorized but unissued shares of the Warrant Stock to such number of shares of the Warrant Stock as shall be sufficient for such purpose.  The parties acknowledge that the Company currently does not have any shares of the Warrant Stock available for issuance and the Company hereby agrees to use its best efforts to take action to call a stockholder meeting and increase its authorized but unissued Warrant Stock as soon as practicable. 

10.              Governing Law.  This Warrant shall be governed by and construed and interpreted in accordance with the laws of the State of Washington, without giving effect to its conflicts of law principles.  All disputes between the parties hereto arising out of or in connection with this Warrant or the Warrant Stock, whether sounding in contract, tort, equity or otherwise, shall be resolved only by state and federal courts located in Spokane, Washington, and the courts to which an appeal therefrom may be taken.  All parties hereto waive any objections to the location of the above-referenced courts, including but not limited to any objection based on lack of jurisdiction, improper venue or forum non conveniens.  Notwithstanding the foregoing, any party obtaining an order or judgment in any of the above-referenced courts may bring an action in a court in another jurisdiction in order to enforce such order or judgment.

14.              Severability.  If one or more provisions of this Warrant are held to be unenforceable under applicable law, such provision(s) shall be excluded from this Warrant and the balance of the Warrant shall be interpreted as if such provision(s) were so excluded and shall be enforceable in accordance with its terms.

15.              Terms Binding.  By acceptance of this Warrant, the Holder accepts and agrees to be bound by all the terms and conditions of this Warrant.

16.              Valid Issuance; Taxes.  All shares of Warrant Stock issued upon the exercise of this Warrant shall be validly issued, fully paid and non-assessable, and the Company shall pay all taxes and other governmental charges that may be imposed in respect of the issue or delivery thereof.  The Company shall not be required to pay any transfer tax or other similar charge imposed in connection with any transfer involved in the issuance of any certificate for shares of Warrant Stock in any name other than that of the Holder of this Warrant.

Appendix A

INVESTMENT REPRESENTATION

The undersigned, _____________________ (the "Holder"), intends to acquire shares of Common Stock (the "Common Stock") of Aura Systems, Inc. (the "Company") from the Company pursuant to the exercise or conversion of a Warrant to purchase Common Stock held by the Holder.  The Common Stock will be issued to the Holder in a transaction not involving a public offering and pursuant to an exemption from registration under the Securities Act of 1933, as amended (the "Securities Act"), and applicable state securities laws.  In connection with such purchase and in order to comply with the exemptions from registration relied upon by the Company, the Holder represents, warrants and agrees as follows:

(a)            The Holder is acquiring the Common Stock for its own account, to hold for investment, and the Holder shall not make any sale, transfer or other disposition of the Common Stock in violation of the Securities Act or the General Rules and Regulations promulgated thereunder by the Securities and Exchange Commission or in violation of any applicable state securities law.  The Holder is an "accredited investor" as such term is defined in Rule 501 of Regulation D promulgated under the Securities Act.

(b)            The Holder has been advised that the Common Stock has not been registered under the Securities Act or state securities laws on the ground that this transaction is exempt from registration, and that reliance by the Company on such exemptions is predicated in part on the Holder's representations set forth herein.

(c)            The Holder has been informed that under the Securities Act, the Common Stock must be held indefinitely unless it is subsequently registered under the Securities Act or unless an exemption from such registration (such as Rule 144) is available with respect to any proposed transfer or disposition by the Holder of the Common Stock.  The Holder further agrees that the Company may refuse to permit the Holder to sell, transfer or dispose of the Common Stock (except as permitted under Rule 144) unless there is in effect a registration statement under the Securities Act and any applicable state securities laws covering such transfer, or unless the Holder furnishes an opinion of counsel reasonably satisfactory to counsel for the Company to the effect that such registration is not required. 

The Holder also understands and agrees that there will be placed on the certificate(s) for the Common Stock or any substitutions therefor, a legend stating in substance:

"The shares represented by this certificate have not been registered under the Securities Act of 1933, as amended (the "Securities Act"), or any state securities laws.  These shares have been acquired for investment purposes and may not be sold or otherwise transferred in the absence of an effective registration statement for these shares under the Securities Act and applicable state securities laws or an opinion of counsel satisfactory to the Company that registration is not required and that an applicable exemption is available."
