    FOR
      VALUE
      RECEIVED, the undersigned, Atlas Technology Group (US), Inc., a Delaware
      corporation, (hereinafter
      referred to as the “Maker”),
      a
      wholly owned subsidiary of Atlas Technology Group, Inc. (f/k/a Tribeworks,
      Inc.), a Delaware corporation (the “Company”),
      promises to pay to the order of West Coast Opportunity Fund, LLC, a Delaware
      limited liability company (“Holder”),
      at
      2151 Alessandro Drive, Suite 100, Ventura, CA 93001, the
      principal amount of Two Million, Five Hundred Thousand and NO/100 DOLLARS
      ($2,500,000.00) (the “Principal”)
      when
      due, upon the Maturity Date (as defined below), acceleration or otherwise (in
      each case in accordance with the terms hereof) together with interest
      (“Interest”)
      at a
      rate equal to five percent (5%) per annum (based on a 365-day year and charged
      on the basis of actual days elapsed, the “Interest
      Rate”)
      from
      the date set out above as the Issuance Date (the “Issuance
      Date”)
      until
      the same becomes due and payable, whether upon the Maturity Date, acceleration
      or otherwise (in each case in accordance with the terms hereof). This Note
      may
      not be sold, assigned, transferred or otherwise conveyed by the Holder. Certain
      capitalized terms used herein are defined in Section 16. 

     

    This
      Amended and Restated Senior Secured Non-Convertible Promissory Note amends,
      restates and supersedes in its entirety the Senior Secured Non-Convertible
      Promissory Note dated July 11, 2007 of Maker in favor of Holder (the
“Prior
      Note”)
      and is
      not a novation of the Prior Note. Upon execution hereof, Holder shall be deemed
      to have advanced hereunder the sum of Two Million, Five Hundred Thousand Dollars
      ($2,500,000) plus such additional amounts owing under the Prior Note, which
      amount is equal to the outstanding principal amount under the Prior Note. All
      references in the Security Agreement, the Securities Purchase Agreement, the
      Guaranty, the Lock-Up Agreements and other related documents, as all are defined
      in the Securities Purchase Agreement, are hereby amended to be a reference
      to
      this Amended and Restated Secured Promissory Note.

     

    1. Payments
      of Principal.
      On the
      Maturity Date, the Maker shall pay to the Holder the unpaid Principal of this
      Promissory Note (this “Note”),
      together with accrued and unpaid Interest. The “Maturity
      Date”
shall
      be December 31, 2008, or (a) such earlier date as may be accelerated by the
      Maker in accordance with the terms hereof, or (b) such later date as may be
      extended at the option of the Holder in the event that, and for so long as,
      an
      Event of Default (as defined below) shall have occurred and be continuing or
      any
      event shall have occurred and be continuing which with the passage of time
      and
      the failure to cure would result in an Event of Default.

    2. Interest;
      Interest Rate.
      Interest on this Note shall commence accruing on the Issuance Date and shall
      be
      payable in arrears for each Payment Period on the first day of the succeeding
      Payment Period during the period beginning on the Issuance Date and ending
      on,
      and including, the Maturity Date (each, an “Interest
      Date”).
      Interest shall be payable on each Interest Date to the Holder. Interest accrues
      at the Interest Rate on all outstanding unpaid Principal owed under this Note
      and all accrued Interest is payable on each Interest Date. Upon the occurrence
      and during the continuance of an Event of Default, the Interest Rate shall
      be
      increased to seven and one-half percent (7.5%) (the “Default
      Rate”).
      In
      the event that such Event of Default is subsequently cured, the adjustment
      referred to in the preceding sentence shall cease to be effective as of the
      date
      of such cure; provided that the Interest as calculated and unpaid at such
      increased rate during the continuance of such Event of Default shall continue
      to
      apply to the extent relating to the days after the occurrence of such Event
      of
      Default through and including the date of cure of such Event of
      Default.

     

    3. Acceleration
      of Payment by the Maker.
      The
      Maker may, from time to time, prepay all or any portion of the Principal or
      Interest of this Note to the Holder without premium or penalty, provided that
      the Maker provide the Holder with ten (10) days notice prior to such
      prepayment.

      Upon Events of Default.

      indemnity;

      days;

     

    vii. any
      Event

      unenforceability of the Security Documents against the Maker or any of its
      Subsidiaries for any reason.

     

    x. any
      default in excess of $100,000 occurs and is continuing under any Indebtedness

    (b) Redemption
      Rights.
      Promptly after the occurrence of an Event of Default with respect to this Note
      or the Other Note, the Maker shall deliver written notice thereof via facsimile
      and overnight courier (an “Event
      of Default Notice”)
      to the
      Holder. At any time after the earlier of the Holder’s receipt of an Event of
      Default Notice and the Holder becoming aware of an Event of Default, the Holder
      may require the Maker to redeem all or any portion of the Note (as “Event
      of Default Redemption”)
      by
      delivering written notice thereof (the “Event
      of Default Redemption Notice”)
      to the
      Maker, which Event of Default Redemption Notice shall indicate the portion
      of
      the Note the Holder is electing to redeem; provided that upon the occurrence
      of
      any default described in Section 4(a)(vi) and 4(a)(viii), the Note shall
      automatically, and without any action on behalf of the Holders, be redeemed
      by
      the Maker. Each portion of the Note subject to redemption by the Maker pursuant
      to this Section 4(b) shall be redeemed by the Maker at a price equal to 100%
      of
      the outstanding Principal amount and accrued and unpaid Interest with respect
      to
      such portion of the Note subject to redemption (the “Event
      of Default Redemption Price”).
      Redemptions required by this Section 4(b) shall be made in accordance with
      the
      provisions of Section 7.

    5. Rights
      Upon Fundamental Transaction and Change of Control.
      

     

    (a) Assumption.
      The
      Maker shall not enter into or be party to a Fundamental Transaction unless
      the
      Successor Entity assumes in writing all of the obligations of the Maker under
      this Note and the other Transaction Documents (as that term is defined in the
      Securities Purchase Agreement) in accordance with the provisions of this Section
      5 pursuant to written agreements in form and substance reasonably satisfactory
      to the Holder and approved by the Holder prior to such Fundamental Transaction.
      Upon the occurrence of any Fundamental Transaction, the Successor Entity shall
      succeed to, and be substituted for (so that from and after the date of such
      Fundamental Transaction, the provisions of this Note referring to the “Maker”
shall refer instead to the Successor Entity), and may exercise every right
      and
      power of the Maker and shall assume all of the obligations of the Maker under
      this Note with the same effect as if such Successor Entity had been named as
      the
      Maker herein. The provisions of this Section 5 shall apply similarly and equally
      to successive Fundamental Transactions and shall be applied without regard
      to
      any limitations on the redemption of this Note.

     

    (b)
      Change
      of Control Redemption Rights.
      No
      later than ten (10) days prior to the consummation of a Change of Control,
      but
      not prior to the public announcement of such Change of Control, the Maker shall
      deliver written notice thereof via facsimile and overnight courier to the Holder
      (a “Change
      of Control Notice”).
      At
      any time during the period beginning after the Holder’s receipt of a Change of
      Control Notice and ending on the date of the consummation of such Change of
      Control (or, in the event a Change of Control Notice is not delivered at least
      ten (10) days prior to a Change of Control, at any time on or after the date
      which is ten (10) days prior to a Change of Control and ending ten (10) days
      after the consummation of such Change of Control), the Holder may require the
      Company to redeem all or any portion of the Note by delivering written notice
      thereof (“Change
      of Control Redemption Notice”)
      to the
      Maker, which Change of Control Redemption Notice shall indicate the portion
      of
      the Note the Holder is electing to redeem. The portion of this Note subject
      to
      redemption pursuant to this Section 4 shall be redeemed by the Maker at a price
      equal to the sum of the Principal amount being redeemed together with accrued
      and unpaid Interest with respect to such amount (the “Change
      of Control Redemption Price”).
      Redemptions required by this Section 4 shall be made in accordance with the
      provisions of Section 7 and shall have priority to payments to stockholders
      in
      connection with a Change of Control.

     

    6. Non-Circumvention.
      The
      Company and Maker hereby covenant and agree that neither the Company nor the
      Maker will, by amendment of its Certificate of Incorporation, Bylaws or through
      any reorganization, transfer of assets, consolidation, merger, scheme of
      arrangement, dissolution, issue or sale of securities, or any other voluntary
      action, avoid or seek to avoid the observance or performance of any of the
      terms
      of this Note, and will at all times in good faith carry out all of the
      provisions of this Note and use commercially reasonable efforts to protect
      the
      rights of the Holder of this Note.

    7. Holder’s
      Redemptions.

     

    (a) Mechanics.
      The
      Maker shall deliver the applicable Event of Default Redemption Price to the
      Holder within five Business Days after the Maker’s receipt of the Required
      Holders’ Event of Default Redemption Notice. If the Holder has submitted a
      Change of Control Redemption Notice in accordance with Section 5(b), the Maker
      shall deliver the applicable Change of Control Redemption Price to the Holder
      concurrently with the consummation of such Change of Control if such notice
      is
      received prior to the consummation of such Change of Control and within ten
      (10)
      Business Days after the Maker’s receipt of such notice otherwise. In the event
      of a redemption of less than all of the Principal of this Note, the Maker shall
      promptly cause to be issued and delivered to the Holder a new Note (in
      accordance with Section 9(b)) representing the outstanding Principal which
      has
      not been redeemed.

     

    (b) Redemption
      by Holders.
      Any
      Event of Default Redemption Notice for redemption or repayment as a result
      of an
      event or occurrence substantially similar to the events or occurrences described
      in Section 4(b) or Section 8 is to be delivered to the Maker by the Holders.
      

     

    8. Covenants.

     

    (a) Security
      Agreement.
      The
      Maker and the Holder shall enter into the Security Agreement, securing this
      Note
      with a first lien security interest in all assets now owned or after acquired
      by
      the Maker for the benefit of the Holder.

     

    (b) Rank.
      The
      indebtedness created by this Note shall be senior to all other Indebtedness
      of
      the Maker and its Subsidiaries.

     

    (c) Incurrence
      of Indebtedness.
      So long
      as this Note is outstanding, the Company and the Maker shall not, and neither
      the Company nor the Maker shall permit any of its Subsidiaries to, directly
      or
      indirectly, incur or guarantee, assume or suffer to exist any Indebtedness,
      other than (i) the Indebtedness evidenced by this Note and the other Note and
      (ii) Permitted Indebtedness that is either unsecured or secured by Permitted
      Liens.

     

    (d) Existence
      of Liens.
      So long
      as this Note is outstanding, the Company and the Maker shall not, and neither
      the Company nor the Maker shall permit any of its Subsidiaries to, directly
      or
      indirectly, allow or suffer to exist any mortgage, lien, pledge, charge,
      security interest or other encumbrance upon or in any property or assets
      (including accounts and contract rights) owned by the Company, the Maker or
      any
      of its Subsidiaries (collectively, “Liens”)
      superior in interest to that of the Holder.

     

    (e) Restricted
      Payments.
      The
      Company and the Maker shall not, and the Company and the Maker shall not permit
      any of its Subsidiaries to, directly or indirectly:

     

    (i) declare
      or pay any dividend or make any other payment or distribution on account of
      the
      Company’s Equity Interests (including, without limitation, any payment in
      connection with any merger or consolidation involving the Company) or to the
      direct or indirect holders of the Company’s Equity Interests in their capacity
      as such, provided, however, that the Subsidiaries may pay dividends to the
      Company and its Subsidiaries;

     

    (ii) purchase,
      redeem or otherwise acquire or retire for value (including, without limitation,

    (iii) make
      any
      payment on or with respect to, accelerate the maturity of, or purchase, redeem,
      defease or otherwise acquire or retire for value any Indebtedness of the Company
      or the Maker, except a payment of interest, principal or other amounts due
      at
      the stated maturity thereof.

     

    (f) Asset
      Sales.
      The
      Company shall not, and neither the Company nor the Maker shall permit any of
      its
      Subsidiaries to, directly or indirectly, consummate any Asset Sale provided,
      however, that the Maker and its Subsidiaries may consummate sales of assets
      or
      Equity Interests to the Maker or its subsidiaries with Holder’s consent, which
      will not be unreasonably withheld or delayed, other than any Asset Sale which
      transfers an asset or an Equity interest to a non-United States Subsidiary,
      which shall not be permitted.

     

    (g) Use
      of
      Proceeds.
      The
      Maker will use amounts received from Holder pursuant to this Note for general
      corporate purposes.
