      otherwise (other than any event addressed by Sections 6.1(a) , 6.1(b) or 6.1(d) ),

      (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 6 with
      respect to the rights and interest thereafter of the Holder of this Warrant,

      the end that the provisions set forth in this Section 6 shall

      shares.




7.  Covenants
      of the Company .

      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

      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.

      case this Warrant shall be mutilated, lost, stolen or destroyed, the Company
      shall issue a new Warrant of like tenor and denomination and deliver the same
      (a) in exchange and substitution for and upon surrender and cancellation of
      any mutilated Warrant, or (b) in lieu of any Warrant lost, stolen or
      destroyed, upon receipt of evidence satisfactory to the Company of the loss,
      theft, or destruction of such Warrant (including, without limitation, a
      reasonably detailed affidavit with respect to the circumstances of any loss,
      theft or destruction), and of indemnity (or, in the case of the initial Holder
      or any other institutional holder, an indemnity agreement) satisfactory to
      the
      Company.

      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 rights granted hereunder contrary to the

      to receipt or exercise of the Warrant or acquiring, holding or disposing of
      the
      Common Stock, and the Holder represents that the Holder has had the opportunity
      to discuss such treatment with the Holder’s tax advisers.




14.  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 are and shall 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.

To:
            Sionix
                Corporation


2082
                Michelson Drive, Suite 304


Irvine,
                CA 92612





The
      undersigned, pursuant to the provisions set forth in the attached Warrant hereby
      irrevocably elects to purchase _____ shares of the Common Stock (the
“ Common
      Stock ”)
      covered by such Warrant and herewith makes payment of $_________, representing
      the [full/partial] purchase price for such shares at the price per share
      provided for in such Warrant.




The
      undersigned hereby agrees to take such other action and execute and deliver
      such
      other documents as Sionix Corporation may require, in connection with the issue
      of shares of Common Stock to the undersigned as aforesaid, in order to comply
      with the provisions of such Warrant.




The
      undersigned is aware that the Common Stock has not been registered under the
      Securities Act of 1933, as amended (the “ Act ”)
      or any
      state securities laws. The undersigned understands that the reliance by the
      Company on exemptions under the Act is predicated in part upon the truth and
      accuracy of the statements of the undersigned in this Subscription
      Form.




The
      undersigned represents and warrants that (1) it has been furnished with all
      information which it deems necessary to evaluate the merits and risks of the
      purchase of the Common Stock; (2) it has had the opportunity to ask questions
      concerning the Common Stock and the Company and all questions posed have been
      answered to its satisfaction; (3) it has been given the opportunity to obtain
      any additional information it deems necessary to verify the accuracy of any
      information obtained concerning the Common Stock and the Company; and (4) it
      has
      such knowledge and experience in financial and business matters that it is
      able
      to evaluate the merits and risks of purchasing the Common Stock and to make
      an
      informed investment decision relating thereto.




The
      undersigned hereby represents and warrants that it is purchasing the Common
      Stock for its own account and not with a view to the sale or distribution of
      all
      or any part of the Common Stock.




The
      undersigned understands that because the Common Stock has not been registered
      under the Act, it must continue to bear the economic risk of the investment
      for
      an indefinite time and the Common Stock cannot be sold unless the Common Stock
      is subsequently registered under applicable federal and state securities laws
      or
      an exemption from such registration is available.









The
      undersigned agrees that it shall in no event sell or distribute or otherwise
      dispose of all or any part of the Common Stock unless (1) there is an effective
      registration statement under the Act and applicable state securities laws
      covering any such transaction involving the Common Stock or (2) the Company
      receives an opinion of legal counsel to the undersigned (concurred in by legal
      counsel for the Company) stating that such transaction is exempt from
      registration or the Company otherwise satisfies itself that such transaction
      is
      exempt from registration.




The
      undersigned consents to the placing of a legend on its certificate for the
      Common Stock stating that the Common Stock has not been registered and setting
      forth the restriction on transfer contemplated hereby and to the placing of
      a
      stop transfer order on the books of the Company and with any transfer agents
      against the Common Stock until the Common Stock may be legally resold or
      distributed without restriction.




The
      undersigned has considered the federal and state income tax implications of
      the
      exercise of the Warrant and the purchase and subsequent sale of the Common
      Stock.
