                amended (“Act”), nor under the securities laws of any state and,

                any
                reason to anticipate any change in his circumstances, financial or
                otherwise, or particular occasion or event which would necessitate
                or
                require his sale or distribution of the Units. No one other than
                the
                undersigned has any beneficial interest in said
                securities;

f.
            The
                undersigned recognizes that the total amount of funds tendered to
                purchase
                the Units is placed at the risk of the business and may be completely
                lost. The undersigned understands that there can be no assurance
                of
                profitable operations and the purchase of Units as an investment
                involves
                risks;





g.
            The
                undersigned realizes that the Units cannot readily be sold, that
                it may
                not be possible to sell or dispose of the Units and therefore the
                Units
                must not be purchased unless the undersigned has liquid assets sufficient
                to assure that such purchase will cause no undue financial difficulties
                and the undersigned can provide for current needs and possible personal
                contingencies;





h.
            The
                undersigned understands that there are substantial restrictions on
                the
                transferability of the Units, and the securities underlying the Units,
                and
                that any certificate or other document evidencing the Units, and
                the
                securities underlying the Units, will have substantially the following
                restrictive legend thereon:





“*The
                securities represented by this certificate have been acquired for
                investment and have not been registered under the Securities Act
                of 1933,
                as amended ("Act") or the securities laws of any state. Such securities
                may not be sold, pledged, hypothecated or otherwise transferred at
                any
                time except upon registration or upon delivery to the Company of
                an
                opinion of counsel satisfactory to the Company that such registration
                is
                not required or evidence satisfactory to the Company that any such
                transfer will not violate the Act or the securities laws of any
                state.”*





i.
            The
                undersigned has not become aware of the offering of Units by any
                form of
                general solicitation or advertising, including, but not limited to
                advertisements, articles, notices or other communications published
                in any
                newspaper, magazine or other similar media or broadcast over television
                or
                radio or any seminar or meeting where those individuals that have
                attended
                have been invited by any such or similar means of general solicitation
                or
                advertising; and





j.
            The
                undersigned is a bona fide resident of the state set forth as his
                ྿residence address࿀ in Subscription Agreement, and that (i) if a
                corporation, partnership, trust, or other form of business organization,
                it has its principal office within such state; (ii) if an individual,
                he
                has his principal residence in such state; and (iii) if a corporation,
                partnership, trust, or other form of business organization which
                was
                organized for the specific purpose of acquiring the Units in the
                Company,
                all of its beneficial owners are residents of such
                state.

**SCHEDULE
      B**


**REGISTRATION
      RIGHTS AGREEMENT**








***THIS
      REGISTRATION RIGHTS AGREEMENT*** (this
“Agreement”) is by and between Kahuna Network Security, Inc., a Nevada
      Corporation (“Company”) (formerly known as Computer Automation Systems, Inc.),
      and the party executing this document on page 5 (the “Holder”), dated as of the
      date set forth on page 5.




**W
      I T N E S S E T H:**





***WHEREAS*** ,
      the
      Holder has purchased the number of shares of Company common stock (“Common
      Stock”) set forth on page 5 of this Agreement (the “Common Stock”),
      and





***WHEREAS*** ,
      the
      Company desires to grant to the Holder certain registration rights in respect
      of
      the resale of the Common Stock.





***NOW,
      THEREFORE*** ,
      in
      consideration of the premises and the mutual covenants contained herein, and
      other good and valuable consideration, the receipt and sufficiency of which
      is
      hereby acknowledged, the parties hereto agree as follows:





**ARTICLE
      ONE**


**Registration
      Rights Agreement**





SECTION
      1.1 Registration Rights Available. The Company agrees to provide Holder with
      respect to the resale of the Common Stock, and any other securities issued
      or
      issuable at any time or from time to time in respect of such securities upon
      a
      stock split, stock dividend, recapitalization or other similar event involving
      the Company (collectively, the “Securities”): (a) one demand secondary offering
      by means of registration pursuant to the Securities Act of 1933, as amended
      (“Securities Act”), subject to the provisions of this Agreement, and (b)
      unlimited rights to register the resale under the Securities Acton a “piggyback”
basis in resale of the Company securities, subject to the provisions of this
      Agreement. The demand registration right and piggyback registration rights
      are
      referred to herein as the “Registration Rights”).





SECTION
      1.2 Demand Registration. With respect to Holder's right to one demand
      registration pursuant to Section 1.1 (a), the parties agree as
      follows:





(a)  Beginning
      on the earlier of (i) May 1, 2004, or (ii) 30 days following the closing of
      a
      private placement of equity or debt securities providing the Company with gross
      proceeds equal to $250,000 minimum, and up to a maximum of $500,000. Holder
      shall be entitled to exercise the demand registration right.





(b)  Holder
      shall provide written notice to the Company indicating his intention to exercise
      the demand registration right at any time prior to January 31, 2006. The Company
      shall promptly, and in any event within 90 days of receiving notice from the
      Holders, use its best efforts to file with the Securities and Exchange
      Commission (the “Commission”) and cause to become effective, a registration
      statement on appropriate form relating to the offer and sale of the Common
      Stock
      by Holder. The Company agrees to provide Holder with notice of the filing of
      such registration and of the filing of any amendments or supplements
      thereto.





(c)  The
      Company agrees to maintain such registration statement in effect for the maximum
      period allowable under the regulations promulgated by the Commission then in
      effect.





(d)  In
      any
      offering pursuant to this Section that becomes effective in which the Holder
      participates, the Company shall use its best efforts to keep available to the
      Holder a prospectus meeting the requirements of Section 10(a)(3) of the
      Securities Act and shall file all amendments and supplements under the
      Securities Act required for that purpose. In any offering pursuant to this
      Section the Company will, as soon as practicable, use its best efforts to effect
      such registration and use its best efforts to effect such qualification and
      compliance as may be so requested and as would permit or facilitate the
      distribution of such Securities, including, without limitation, registration
      under the Securities Act, appropriate qualifications under applicable blue-sky
      or other state securities laws, appropriate compliance with any other
      governmental requirements and listing on a national securities exchange on
      which
      the Common Stock is then listed or inter-dealer quotation system.





SECTION
      1.3 Piggyback Registration. With respect to Holder’s right to piggyback on a
      firm commitment underwriting or a self-underwritten offering of the Company
      securities pursuant to Section 1.1, the parties agree as follows:





(a)  Pursuant
      to Section 1.1, the Company will (i) promptly give to the Holder notice of
      any
      registration relating to a public offering of the Company securities other
      a
      registration on Form S-4 or Form S-8 (each as promulgated under the Securities
      Act) or their then equivalents relating to equity securities to be issued solely
      in connection with any acquisition of any entity or business or equity
      securities issuable in connection with the stock option or other employee
      benefit plans; and (ii) include in such registration (and related qualification
      under blue sky laws or other compliance, unless such expense or terms of such
      qualification is unreasonable in comparison to the number of securities to
      be
      registered in such jurisdiction, as determined in the sole discretion of the
      Company), and in the underwriting involved therein, all the Securities of the
      Holder, with or without written request.





(b)  The
      right
      of Holder to registration pursuant to Section 1.1 shall be conditioned upon
      Holder’s participation in such underwriting, and the inclusion of the Securities
      in the underwriting shall be limited to the extent provided herein. The Holder
      and all other holders proposing to distribute their securities through such
      underwriting shall (together with the Company and the other holders distributing
      their securities through such underwriting) enter into an underwriting agreement
      in customary form with the managing underwriter selected for such underwriting
      by the Company. Notwithstanding any other provision of this Agreement, if the
      managing underwriter determines that marketing factors require a limitation
      of
      the number of shares to be underwritten, the managing underwriter may limit
      some
      or all of the Securities that may be included in the registration and
      underwriting as follows: the number of Securities that may be included in the
      registration and underwriting by the Holder shall be determined by multiplying
      the number of shares of Securities of all selling shareholders of the Company
      which the managing underwriter is willing to include in such registration and
      underwriting, times a fraction, the numerator of which is the number of
      Securities requested to be included in such registration and underwriting by
      the
      Holder, and the denominator of which is the total number of Securities which
      all
      selling shareholders of the Company have requested to have included in such
      registration and underwriting. To facilitate the allocation of shares in
      accordance with the above provisions, the Company may round the number of shares
      allocable to any such person to the nearest 100 shares. If the Holder
      disapproves of the terms of any such underwriting, it may elect to withdraw
      therefrom by written notice to the Company and the managing underwriter,
      delivered not less than seven days before the effective date. Any securities
      excluded or withdrawn from such underwriting shall be withdrawn from such
      registration, and shall not be transferred in a public distribution prior to
      120
      days after the effective date of the registration statement relating thereto,
      or
      such other shorter period of time as the underwriters may require.





SECTION
      1.3 Registration Procedure. With respect to the Registration Right, the
      following provisions shall apply:





(a)  Holder
      shall be obligated to furnish to the Company such information regarding the
      Securities and the proposed manner of distribution of the Securities as the
      Company and the underwriters (if any) may request in writing and as shall be
      required in connection with any registration, qualification or compliance
      referred to herein and shall otherwise cooperate with the Company and the
      underwriters (if any) in connection with such registration, qualification or
      compliance.





(b)  With
      a
      view to making available the benefits of certain rules and regulations of the
      Commission which may at any time permit the sale of the Restricted Securities
      (used herein as defined in Rule 144 under the Securities Act) to the public
      without registration, the Company agrees to use its best lawful efforts
      to:





(i)  Make
      and
      keep public information available, as those terms are understood and defined
      in
      Rule 144 under the Securities Act, at all times during which the Company is
      subject to the reporting requirements of the Securities Exchange Act of 1934,
      as
      amended (the “Exchange Act”);





(ii)  File
      with
      the Commission in a timely manner all reports and other documents required
      of
      the Company under the Securities Act and the Exchange Act (at all times during
      which the Company is subject to such reporting requirements); and





(iii)  So
      long
      as Holder owns any Restricted Securities, to furnish to Holder forthwith upon
      request a written statement by the Company as to its compliance with the
      reporting requirements of said Rule 144 and with regard to the Securities Act
      and the Exchange Act (at all times during which the Company is subject to such
      reporting requirements), a copy of the most recent annual or quarterly report
      of
      the Company, and such other reports and documents of the Company and other
      information in the possession of or reasonably obtainable by the Company as
      Holder may reasonably request in availing themselves of any rule or regulation
      of the Commission allowing Holder to sell any such securities without
      registration.





(c)  The
      Company agrees that it will furnish to Holder such number of prospectuses,
      offering circulars or other documents incident to any registration,
      qualification or compliance referred to herein as provided or, if not otherwise
      provided, as the Holder from time to time may reasonably request.





(d)  Except
      for the legal fees of Holder and any sales commissions that may be paid by
      Holder, all expenses of any registrations permitted pursuant to this Agreement
      and of all other offerings by the Company (including, but not limited to, the
      expenses of any qualifications under the blue-sky or other state securities
      laws
      and compliance with governmental requirements of preparing and filing any
      post-effective amendments required for the lawful distribution of the Securities
      to the public in connection with such registration, of supplying prospectuses,
      offering circulars or other documents) will be paid by the Company.





(e)  The
      Registration Right of this Agreement, subject to the terms and conditions
      hereof, shall be available to any subsequent holder of the Securities owned
      by
      Holder. Each subsequent holder entitled to the Registration Right under this
      Agreement shall be bound by the terms and subject to the obligations of this
      Agreement as though it were an original signatory hereto.





**ARTICLE
      TWO**


**Indemnification**





SECTION
      2.1 Indemnification by the Company. In the event of any registration of the
      Securities of the Company under the Securities Act, the Company agrees to
      indemnify and hold harmless Holder and each other person who participates as
      an
      underwriter in the offering or sale of such securities against any and all
      claims, demands, losses, costs, expenses, obligations, liabilities, joint or
      several, damages, recoveries and deficiencies, including interest, penalties
      and
      attorneys’ fees (collectively, “Claims”), to which Holder may become subject
      under the Securities Act or otherwise, insofar as such Claims (or actions or
      proceedings, whether commenced or threatened, in respect thereof) arise out
      of
      or are based on any untrue statement or alleged untrue statement of any material
      fact contained in any registration statement under which Holder’s Securities
      were registered under the Securities Act, any preliminary prospectus, final
      prospectus or summary prospectus contained therein, or any amendment or
      supplement thereto, or any omission or alleged omission to state therein a
      material fact required to be stated therein or necessary to make the statements
      therein not misleading, and the Company will reimburse Holder and each such
      underwriter for any legal or any other expenses reasonably incurred by them
      in
      connection with investigating or defending any such Claim (or action or
      proceeding in respect thereof); provided that the Company shall not be liable
      in
      any such case to the extent that any such Claim (or action or proceeding in
      respect thereof) or expense arises out of or is based on an untrue statement
      or
      alleged untrue statement or omission or alleged omission made in such
      registration statement, any such preliminary prospectus, final prospectus,
      summary prospectus, amendment or supplement in reliance on and in conformity
      with written information furnished to the Company through an instrument duly
      executed by Holder specifically stating that it is for use in the preparation
      thereof. Such indemnity shall remain in full force and effect regardless of
      any
      investigation made by or on behalf of Holder or any such underwriter and shall
      survive the transfer of the Securities by Holder.





SECTION
      2.2 Indemnification by Holder. The Company may require, as a condition to
      including the Securities in any registration statement filed pursuant to this
      Agreement, that the Company shall have received an undertaking satisfactory
      to
      it from Holder, to indemnify and hold harmless (in the same manner and to the
      same extent as set forth in Section 2.1) the Company, each director of the
      Company, each officer of the Company and each other person, if any, who controls
      the Company, within the meaning of the Securities Act, with respect to any
      statement or alleged statement in or omission or alleged omission from such
      registration statement, any preliminary prospectus contained therein, or any
      amendment or supplement thereto, if such statement or alleged statement or
      omission or alleged omission was made in reliance on and in conformity with
      written information furnished to the Company through an instrument duly executed
      by Holder specifically stating that it is for use in the preparation of such
      registration statement, preliminary prospectus, final prospectus, summary
      prospectus, amendment or supplement. Notwithstanding the foregoing, the maximum
      liability hereunder which any holder shall be required to suffer shall be
      limited to the net proceeds to such Holder from the Securities sold by such
      Holder in the offering. Such indemnity shall remain in full force and effect,
      regardless of any investigation made by or on behalf of the Company or any
      such
      director, officer or controlling person and shall survive the transfer of the
      Securities by Holder.





SECTION
      2.3 Notices of Claims, etc. Promptly after receipt by an indemnified party
      of
      notice of the commencement of any action or proceeding involving a Claim
      referred to in this Article Two, such indemnified party will, if a claim in
      respect thereof is to be made against an indemnifying party, give written notice
      to the latter of the commencement of such action, provided that the failure
      of
      any indemnified party to give notice as provided herein shall not relieve the
      indemnifying party of its obligations under this Article Two, except to the
      extent that the indemnifying party is actually prejudiced by such failure to
      give notice. In case any such action is brought against an indemnifying party,
      unless in such indemnified party’s reasonable judgment a conflict of interest
      between such indemnified and indemnifying parties may exist in respect of such
      Claim, the indemnifying party shall be entitled to participate in and to assume
      the defense thereof, jointly with any other indemnifying party similarly
      notified to the extent that it may wish, with counsel reasonably satisfactory
      to
      such indemnified party, and after notice from the indemnifying party to such
      indemnified party of its election so to assume the defense thereof, the
      indemnifying party shall not be liable to such indemnified party for any legal
      or other expenses subsequently incurred by the latter in connection with the
      defense thereof other than reasonable costs of investigation. No indemnifying
      party shall, without the consent of the indemnified party, consent to entry
      of
      any judgment or enter into any settlement that does not include as an
      unconditional term thereof the giving by the claimant or plaintiff to such
      indemnified party of a release from all liability in respect of such
      Claim.





SECTION
      2.4 Indemnification Payments. The indemnification required by this Article
      shall
      be made by periodic payments of the amount thereof during the course of the
      investigation or defense, as and when bills are received or expense, loss,
      damage or liability is incurred.





**ARTICLE
      THREE**


**Miscellaneous**





SECTION
      3.1 Consent to Amendments. Except as otherwise expressly provided herein, the
      provisions of this Agreement may be amended or waived only by the written

      of
      the respective successors and assigns of the parties hereto, but only if so
      expressed in writing.


SECTION
      3.4 Severability. Whenever possible, each provision of this Agreement will
      be
      interpreted in such a manner as to be effective and valid under applicable
      law,
      but if any provision of this Agreement is held to be prohibited by or invalid
      under applicable law, such provision will be ineffective only to the extent
      of
      such prohibition or invalidity, without invalidating the remainder of this
      Agreement.





SECTION
      3.5 Delays or Omissions. No failure to exercise or delay in the exercise of
      any
      right, power or remedy accruing to Holder on any breach or default of the
      Company under this Agreement shall impair any such right, power or remedy nor
      shall it be construed to be a waiver of any such breach or default.





SECTION
      3.6 Remedies Cumulative. All remedies under this Agreement, or by law or
      otherwise afforded to any party hereto shall be cumulative and not
      alterative.
