      of Shares Issuable upon Exercise.
      From and after the Issue Date through and including the Expiration Date,

      1.2.
	
      Full
      Exercise.
      This Warrant may be exercised in full by the Holder hereof by delivery of
      an original or facsimile copy of the form of subscription attached as
      Exhibit A hereto (the “Subscription Form") duly executed by such
      Holder and surrender of the original Warrant within four (4) days of

      Warrant Agent (as provided hereinafter), accompanied by payment, in cash,
      wire transfer or by certified or official bank check payable to the order

      Fair Market Value of a share of Common Stock as of a particular date (the
      "Determination Date") shall mean:

      respectively, reported for the last business day immediately preceding the
      Determination Date;

	 	 	 	
      (b)
	
      If
      the Company's Common Stock is not traded on an exchange or on the NASDAQ
      National Market System, the NASDAQ SmallCap Market or the American Stock

      day immediately preceding the Determination
Date;

	 	 	 	
      (c)
	
      Except

      then standing of the American Arbitration Association, before a single

      (d)
	
      If
      the Determination Date is the date of a liquidation, dissolution or
      winding up, or any event deemed to be a liquidation, dissolution or
      winding up pursuant to the Company's charter, then all amounts to be
      payable per share to holders of the Common Stock pursuant to the charter
      in the event of such liquidation, dissolution or winding up, plus all
      other amounts to be payable per share in respect of the Common Stock in
      liquidation under the charter, assuming for the purposes of this clause
      (d) that all of the shares of Common Stock then issuable upon
      exercise of all of the Warrants are outstanding at the Determination
      Date.

	 	 	
      1.5.
	
      Company
      Acknowledgment.
      The Company will, at the time of the exercise of the Warrant, upon the
      request of the Holder hereof acknowledge in writing its continuing
      obligation to afford to such Holder any rights to which such Holder shall
      continue to be entitled after such exercise in accordance with the
      provisions of this Warrant. If the Holder shall fail to make any such
      request, such failure shall not affect the continuing obligation of the
      Company to afford to such Holder any such
rights.

	 	 	
      1.6.
	
      Trustee
      for Warrant Holders.
      In the event that a bank or trust company shall have been appointed as
      trustee for the Holder of the Warrants pursuant to Subsection 3.2,
      such bank or trust company shall have all the powers and duties of a
      warrant agent (as hereinafter described) and shall accept, in its own name
      for the account of the Company or such successor person as may be entitled
      thereto, all amounts otherwise payable to the Company or such successor,
      as the case may be, on exercise of this Warrant pursuant to this
      Section 1. 

	 	 	
      1.7
	
      Delivery
      of Stock Certificates, etc. on Exercise.
      The Company agrees that the shares of Common Stock purchased upon exercise
      of this Warrant shall be deemed to be issued to the Holder hereof as the
      record owner of such shares as of the close of business on the date on
      which this Warrant shall have been surrendered and payment made for such
      shares as aforesaid. As soon as practicable after the exercise of this
      Warrant in full or in part, and in any event within four (4)
      business
      days thereafter, the Company at its expense (including the payment by it
      of any applicable issue taxes) will cause to be issued in the name of and
      delivered to the Holder hereof, or as such Holder (upon payment by such
      Holder of any applicable transfer taxes) may direct in compliance with
      applicable securities laws, a certificate or certificates for the number
      of duly and validly issued, fully paid and nonassessable shares of Common
      Stock (or Other Securities) to which such Holder shall be entitled on such
      exercise, plus, in lieu of any fractional share to which such Holder would
      otherwise be entitled, cash equal to such fraction multiplied by the then
      Fair Market Value of one full share of Common Stock, together with any
      other stock or other securities and property (including cash, where
      applicable) to which such Holder is entitled upon such exercise pursuant
      to Section 1 or otherwise. 

180

	 	
      2.
	
      Cashless
      Exercise.

	 	 	 	
      (a)
	
      If
      a Registration Statement (as defined in the Subscription Agreement)
      (“Registration Statement”) is effective and the Holder may sell its shares
      of Common Stock upon exercise hereof pursuant to the Registration
      Statement, this Warrant may be exercisable in whole or in part for cash
      only as set forth in Section 1 above. If no such Registration Statement is
      available
      during the time that such Registration Statement is required to be
      effective pursuant to the terms of the Subscription Agreement, then
      payment upon exercise may be made at the option of the Holder either in
      (i) cash, wire transfer or by certified or official bank check
      payable to the order of the Company equal to the applicable aggregate
      Purchase Price, (ii) by delivery of Common Stock issuable upon exercise of
      the Warrants in accordance with Section (b) below or
      (iii) by a combination of any of the foregoing methods, for the
      number of Common Stock specified in such form (as such exercise number
      shall be adjusted to reflect any adjustment in the total number of shares
      of Common Stock issuable to the holder per the terms of this Warrant) and
      the holder shall thereupon be entitled to receive the number of duly
      authorized, validly issued, fully-paid and non-assessable shares of Common
      Stock (or Other Securities) determined as provided
  herein.

	 	 	 	
      (b)
	
      If
      the Fair Market Value of one share of Common Stock is greater than the
      Purchase Price (at the date of calculation as set forth below), in lieu of
      exercising this Warrant for cash, the holder may elect to receive shares
      equal to the value (as determined below) of this Warrant (or the portion
      thereof being cancelled) by surrender of this Warrant at the principal
      office of the Company together with the properly endorsed Subscription
      Form in which event the Company shall issue to the holder a number of
      shares of Common Stock computed using the following
    formula:

	 	 	 	 	
      X=Y
      (A-B)

	 	 	 	 	
      A

	 	 	 	 	
      Where X=
      the number of shares of Common Stock to be issued to the
      holder

	 	 	 	 	 
	 	 	 	 	
      Y =
      the number of shares of Common Stock purchasable under the Warrant or, if
      only a portion of the Warrant is being exercised, the portion of the
      Warrant being exercised (at the date of such
  calculation)

	 	 	 	 	 
	 	 	 	 	
      A =
      the Fair Market Value of one share of the Company’s Common Stock (at the
      date of such calculation)

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

	 	 	 	
      (c)
	
      The
      Holder may employ the cashless exercise feature described in Section (b)
      above only during the pendency of a Non-Registration Event as described in
      Section 11 of the Subscription Agreement.

For
purposes of Rule 144 promulgated under the 1933 Act, it is intended, understood
and acknowledged that the Warrant Shares issued in a cashless exercise
transaction shall be deemed to have been acquired by the Holder, and the holding
period for the Warrant Shares shall be deemed to have commenced, on the date
this Warrant was originally issued pursuant to the Subscription
Agreement.

181

	 	
      3.
	
      Adjustment
      for Reorganization, Consolidation, Merger,
etc.

	 	 	
      3.1.
	
      Reorganization,
      Consolidation, Merger, etc.
      In case at any time or from time to time, the Company shall
      (a) effect a reorganization, (b) consolidate with or merge into
      any other person or (c) transfer all or substantially all of its
      properties or assets to any other person under any plan or arrangement
      contemplating the dissolution of the Company, then, in each such case, as
      a condition to the consummation of such a transaction, proper and adequate
      provision shall be made by the Company whereby the Holder of this Warrant,
      on the exercise hereof as provided in Section 1, at any time after
      the consummation of such reorganization, consolidation or merger or the
      effective date of such dissolution, as the case may be, shall receive, in
      lieu of the Common Stock (or Other Securities) issuable on such exercise
      prior to such consummation or such effective date, the stock and other
      securities and property (including cash) to which such Holder would have
      been entitled upon such consummation or in connection with such
      dissolution, as the case may be, if such Holder had so exercised this
      Warrant, immediately prior thereto, all subject to further adjustment
      thereafter as provided in Section 4.

	 	 	
      3.2.
	
      Dissolution.
      In the event of any dissolution of the Company following the transfer of
      all or substantially all of its properties or assets, the Company, prior
      to such dissolution, shall at its expense deliver or cause to be delivered
      the stock and other securities and property (including cash, where
      applicable) receivable by the Holder of the Warrants after the effective
      date of such dissolution pursuant to this Section 3 to a bank or
      trust company (a "Trustee") having its principal office in New York,
      NY, as trustee for the Holder of the Warrants.

	 	 	
      3.3.
	
      Continuation
      of Terms.
      Upon any reorganization, consolidation, merger or transfer (and any
      dissolution following any transfer) referred to in this Section 3,
      this Warrant shall continue in full force and effect and the terms hereof
      shall be applicable to the Other Securities and property receivable on the
      exercise of this Warrant after the consummation of such reorganization,
      consolidation or merger or the effective date of dissolution following any
      such transfer, as the case may be, and shall be binding upon the issuer of
      any Other Securities, including, in the case of any such transfer, the
      person acquiring all or substantially all of the properties or assets of
      the Company, whether or not such person shall have expressly assumed the
      terms of this Warrant as provided in Section 4. In the event this
      Warrant does not continue in full force and effect after the consummation
      of the transaction described in this Section 3, then only in such
      event will the Company's securities and property (including cash, where
      applicable) receivable by the Holder of the Warrants be delivered to the
      Trustee as contemplated by
Section 3.2.

182

	 	 	
      3.4
	
      Share
      Issuance.
      Until the Expiration Date, if the Company shall issue any Common Stock
      except for the Excepted Issuances (as defined in the Subscription
      Agreement), prior to the complete exercise of this Warrant for a
      consideration less than the Purchase Price that would be in effect at the
      time of such issue, then, and thereafter successively upon each such
      issue, the Purchase Price shall be reduced to such other lower issue
      price. For purposes of this adjustment, the issuance of any security or
      debt instrument of the Company carrying the right to convert such security
      or debt instrument into Common Stock or of any warrant, right or option to
      purchase Common Stock shall result in an adjustment to the Purchase Price
      upon the issuance of the above-described security, debt instrument,
      warrant, right, or option and again at any time upon any subsequent
      issuances of shares of Common Stock upon exercise of such conversion or
      purchase rights if such issuance is at a price lower than the Purchase
      Price in effect upon such issuance. The reduction of the Purchase Price
      described in this Section 3.4 is in addition to the other rights of the
      Holder described in the Subscription
Agreement.

	 	
      4.
	
      Extraordinary
      Events Regarding Common Stock.
      In the event that the Company shall (a) issue additional shares of
      the Common Stock as a dividend or other distribution on outstanding Common
      Stock, (b) subdivide its outstanding shares of Common Stock, or
      (c) combine its outstanding shares of the Common Stock into a smaller
      number of shares of the Common Stock, then, in each such event, the
      Purchase Price shall, simultaneously with the happening of such event, be
      adjusted by multiplying the then Purchase Price by a fraction, the
      numerator of which shall be the number of shares of Common Stock
      outstanding immediately prior to such event and the denominator of which
      shall be the number of shares of Common Stock outstanding immediately
      after such event, and the product so obtained shall thereafter be the
      Purchase Price then in effect. The Purchase Price, as so adjusted, shall
      be readjusted in the same manner upon the happening of any successive
      event or events described herein in this Section 4. The number of
      shares of Common Stock that the Holder of this Warrant shall thereafter,
      on the exercise hereof as provided in Section 1, be entitled to
      receive shall be adjusted to a number determined by multiplying the number
      of shares of Common Stock that would otherwise (but for the provisions of
      this Section 4) be issuable on such exercise by a fraction of which
      (a) the numerator is the Purchase Price that would otherwise (but for
      the provisions of this Section 4) be in effect, and (b) the
      denominator is the Purchase Price in effect on the date of such
      exercise.

	 	
      5.
	
      Certificate
      as to Adjustments.
      In each case of any adjustment or readjustment in the shares of Common
      Stock (or Other Securities) issuable on the exercise of the Warrants, the
      Company at its expense will promptly cause its Chief Financial Officer or
      other appropriate designee to compute such adjustment or readjustment in
      accordance with the terms of the Warrant and prepare a certificate setting
      forth such adjustment or readjustment and showing in detail the facts upon
      which such adjustment or readjustment is based, including a statement of
      (a) the consideration received or receivable by the Company for any
      additional shares of Common Stock (or Other Securities) issued or sold or
      deemed to have been issued or sold, (b) the number of shares of
      Common Stock (or Other Securities) outstanding or deemed to be
      outstanding, and (c) the Purchase Price and the number of shares of
      Common Stock to be received upon exercise of this Warrant, in effect
      immediately prior to such adjustment or readjustment and as adjusted or
      readjusted as provided in this Warrant. The Company will forthwith mail a
      copy of each such certificate to the Holder of the Warrant and any Warrant
      Agent of the Company (appointed pursuant to Section 11
      hereof).

183

	 	
      6.
	
      Reservation
      of Stock, etc. Issuable on Exercise of Warrant; Financial
      Statements.
      The Company will at all times reserve and keep available, solely for
      issuance and delivery on the exercise of the Warrants, all shares of
      Common Stock (or Other Securities) from time to time issuable on the
      exercise of the Warrant. This Warrant entitles the Holder hereof to
      receive copies of all financial and other information distributed or
      required to be distributed to the holders of the Company's Common Stock.
      

	 	
      7.
	
      Assignment;
      Exchange of Warrant.
      Subject to compliance with applicable securities laws, this Warrant, and
      the rights evidenced hereby, may be transferred by any registered holder
      hereof (a "Transferor"). On the surrender for exchange of this Warrant,
      with the Transferor's endorsement in the form of Exhibit B attached
      hereto (the “Transferor Endorsement Form") and together with an opinion of
      counsel reasonably satisfactory to the Company that the transfer of this
      Warrant will be in compliance with applicable securities laws, the Company
      (at its expense, twice only, but with payment by the Transferor of any
      applicable transfer taxes), will issue and deliver to or on the order of
      the Transferor thereof a new Warrant or Warrants of like tenor, in the
      name of the Transferor and/or the transferee(s) specified in such
      Transferor Endorsement Form (each a "Transferee"), calling in the
      aggregate on the face or faces thereof for the number of shares of Common
      Stock called for on the face or faces of the Warrant so surrendered by the
      Transferor. No such transfers shall result in a public distribution of the
      Warrant.

	 	
      8.
	
      Replacement
      of Warrant.
      On receipt of evidence reasonably satisfactory to the Company of the loss,
      theft, destruction or mutilation of this Warrant and, in the case of any
      such loss, theft or destruction of this Warrant, on delivery of an
      indemnity agreement or security reasonably satisfactory in form and amount
      to the Company or, in the case of any such mutilation, on surrender and
      cancellation of this Warrant, the Company (at its expense, twice only),
      will execute and deliver, in lieu thereof, a new Warrant of like
      tenor.

	 	
      9.
	
      Registration
      Rights.
      The Holder of this Warrant has been granted certain registration rights by
      the Company. These registration rights are set forth in the Subscription
      Agreement. The terms of the Subscription Agreement are incorporated herein
      by this reference.

	 	
      10.
	
      Maximum
      Exercise.
      The Holder shall not be entitled to exercise this Warrant on an exercise
      date nor may the Company exercise its right to give a Call Notice (as
      defined in Section 11) in connection with that number of Common Stock
      which would be in excess of the sum of (i) the number of shares of
      Common Stock beneficially owned by the Holder and its affiliates on an
      exercise date or Call Date, and (ii) the number of Common Stock
      issuable upon the exercise of this Warrant with respect to which the
      determination of this limitation is being made on an exercise date or Call
      Date, which would result in beneficial ownership by the Holder and its
      affiliates of more than 4.99% of the outstanding Common Stock on such
      date. For the purposes of the immediately preceding sentence, beneficial
      ownership shall be determined in accordance with
      Section 13(d) of the Securities Exchange Act of 1934, as
      amended, and Regulation 13d-3 thereunder. Subject to the foregoing, the
      Holder shall not be limited to aggregate exercises which would result in
      the issuance of more than 4.99%. The
      Holder may waive the conversion limitation described in this Section 10,
      in whole or in part and increase the amount that may be beneficially
      owned, upon and effective after 61 days prior written notice to the
      Company.
      The Holder may allocate which of the equity of the Company deemed
      beneficially owned by the Subscriber shall be included in the 4.99% amount
      described above and which shall be allocated to the excess above

      with and governed by the following:

	 	 	
      (a)
	
      The

      provision of Section 14 of this Warrant.

	 	 	
      (b)
	
      The
      Company's right to exercise the Warrant Call shall commence twenty (20)
      trading days after the actual effective date of a Registration Statement
      described in Section 11.1(iv) of the Subscription Agreement and end thirty
      trading days prior to the Expiration Date.

	 	 	
      (c)
	
      The
      number of shares of Common Stock to be issued upon exercise of the Warrant
      which are subject to a Call Notice must be registered in a Registration
      Statement effective from thirty (30) trading days prior to the Call Date
      and through the date such Common Stock is actually delivered to the
      Warrant Holder (“Delivery Date”).

	 	 	
      (d)
	
      A
      Call Notice may be given not sooner than ten (10) trading days after the
      prior Call Date.

	 	 	
      (e)
	
      One-half
      of the Warrant Shares represented by this Warrant may be called during the
      two calendar months following the two consecutive calendar months during
      which the Company has sold and delivered one hundred (100) “AXP 1000”
      units. All the Warrant Shares represented by this may be called during the

      (f)
	
      The
      Common Stock must be listed on the Principal Market for the Lookback
      Period and through the Delivery Date.

	 	 	
      (g)
	
      The
      Company shall not have received a notice from the Principal Market during
      the sixty trading days prior to the Call Date that the Company or its
      Common Stock does not meet the requirements for continued quotation,
      listing or trading on the Principal Market.

	 	 	
      (h)
	
      The
      Company and the Common Stock shall meet the requirements for continued
      quotation, listing or trading on the Principal Market for the Lookback
      Period and through the Delivery Date.

	 	 	
      (i)
	
      Unless
      otherwise agreed to by the Holder of this Warrant, a Call Notice must be
      given to all Warrant Holders who receive Warrants similar to this Warrant
      (in terms of exercise price and other principal terms) issued on or about
      the same Issue Date as this Warrant, in proportion to the amounts of
      Common Stock which may be purchased by the respective Warrant Holders in
      accordance with the respective Warrants held by
each.

	 	 	
      (j)
	
      The
      Warrant Holder shall exercise his Warrant rights and purchase the Called
      Warrant Shares and pay for same within ten trading days after the Call
      Date. If the Warrant Holder fails to timely pay the amount required by the
      Warrant Call, the Company’s sole remedy shall be to cancel a corresponding
      amount of this Warrant.

185

	 	 	
      (k)
	
      The
      Company may not exercise the right to Call this Warrant after the
      occurrence of a default by the Company of a material term of this Warrant
      or the Transaction Documents (as defined in the Subscription Agreement) or
      the Notes referred to in the Subscription
Agreement.

STANDSTILL AGREEMENT

This
AGREEMENT (the "Agreement") is made as of the ___ day of April, 2005, by the
signatories
hereto (each a "Holder"), in connection with his ownership of equity of Energy
& Engine Technology Corporation, a Nevada corporation (the
"Company").

NOW,
THEREFORE, for good and valuable consideration, the sufficiency and receipt of
which consideration are hereby acknowledged, Holder agrees as
follows:

	 	
      1.
	
      Background.

	 	 	
      a.
      
	
      Holder
      is the beneficial owner of the amount of shares of the Common Stock,
      $0.001 par value, of the Company (“Common Stock”) designated on the
      signature page hereto.

	 	 	
      b.
	
      Holder
      acknowledges that the Company has entered into or will enter into an
      agreement with each subscriber (“Subscription Agreement”) to the
      Company’s
      secured
      convertible promissory notes and warrants
      (the “Subscribers”), for the sale of an aggregate of up to $1,500,000 of
      secured
      convertible promissory notes and warrants to
      the Subscribers (the “Offering”). Holder understands that, as a condition
      to proceeding with the Offering, the Subscribers have required, and the
      Company has agreed to provide an agreement from the Holder to refrain from
      selling any securities of the Company for a period of twelve months from
      the Actual Effective Date, as defined in the Subscription Agreement (the
      "Restriction Period"). 

	 	
      2.
	
      Share
      Restriction.

	 	 	
      a.
	
      Holder
      hereby agrees that during the Restriction Period, the Holder will not sell
      or otherwise dispose of any shares of Common Stock or any options,
      warrants or other rights to purchase shares of Common Stock or any other
      security of the Company which Holder owns or has a right to acquire as of
      the date hereof or hereafter, other than in connection with an offer made
      to all shareholders of the Company or any merger, consolidation or similar
      transaction involving the Company. Holder further agrees that the Company
      is authorized to and the Company agrees to place "stop orders" on its
      books to prevent any transfer of shares of Common Stock or other
      securities of the Company held by Holder in violation of this
      Agreement.

	 	 	
      b.
	
      Any
      subsequent issuance to and/or acquisition of shares or the right to
      acquire shares by Holder will be subject to the provisions of this
      Agreement.

	 	 	
      c.
	
      The
      foregoing restrictions notwithstanding the Holder may sell during the
      Restriction Period, up to five percent (5%) of the amount of shares of
      Common Stock actually owned by Holder on the Initial Closing Date (as
      defined in the Subscription Agreement). In no event may more than one
      percent (1%) of the amount of shares of Common Stock actually owned by the
      Holder on the Initial Closing Date be sold during any thirty (30) day
      period.

190

	 	 	
      d.
      
	
      Notwithstanding
      the foregoing restrictions on transfer, the Holder may, at any time and
      from time to time during the Restriction Period, transfer the Common Stock
      (i) as bona fide gifts or transfers by will or intestacy, (ii) to any
      trust for the direct or indirect benefit of the undersigned or the
      immediate family of the Holder, provided that any such transfer shall not
      involve a disposition for value, (iii) to a partnership or LLC which is
      the general partner of a partnership or LLC of which the Holder is a
      general partner or manager, provided, that, in the case of any gift or
      transfer described in clauses (i), (ii) or (iii), each donee or transferee
      agrees in writing to be bound by the terms and conditions contained herein
      in the same manner as such terms and conditions apply to the undersigned.
      For purposes hereof, "immediate family" means any relationship by blood,
      marriage or adoption, not more remote than first
cousin.

	 	
      3.
	
      Miscellaneous.

	 	 	
      a.
	
      At
      any time, and from time to time, after the signing of this Agreement
      Holder will execute such additional instruments and take such action as
      may be reasonably requested by the Subscribers to carry out the intent and
      purposes of this Agreement.

	 	 	
      b.
	
      This
      Agreement shall be governed, construed and enforced in accordance with the
      laws of the State of New York
      without regard to conflicts of laws principles that would result in the
      application of the substantive laws of another jurisdiction, except to the
      extent that the securities laws of the state in which Holder resides and
      federal securities laws may apply. Any proceeding brought to enforce this
      Agreement may be brought exclusively in courts sitting in New York County,
      New York.

	 	 	
      c.
	
      This
      Agreement contains the entire agreement of the Holder with respect to the
      subject matter hereof.

	 	 	
      d.
	
      This
      Agreement shall be binding upon Holder, its legal representatives,
      successors and assigns.

	 	 	
      e.
	
      This
      Agreement may be signed and delivered by facsimile and such facsimile
      signed and delivered shall be enforceable.

	 	 	
      f.
	
      The
      Company agrees not to take any action or allow any act to be taken which
      would be inconsistent with this Agreement.

IN
WITNESS WHEREOF, and intending to be legally bound hereby, Holder has executed
this Agreement as of the day and year first above written.
