      business and is in good standing in each jurisdiction in which the
      character of properties occupied, owned or held under lease by such

      would not have a material adverse effect on the business, operations,
      assets, liabilities or condition (financial or otherwise) of MYTURN, taken
      as a whole.

      1.3b  VALID ISSUANCE OF WARRANTS AND COMMON STOCK. The Warrants, when

1.4   REPRESENTATIONS AND WARRANTIES OF GEOWORKS.

      GEOWORKS hereby represents and warrants to MYTURN as of the date of this
Agreement as follows:

      1.4a  AUTHORITY. GEOWORKS has all requisite legal and corporate power to
      enter into this Agreement and to perform its obligations under the terms
      of, or contemplated by, this Agreement.

      1.4b  AUTHORIZATION. All corporate action on the part of GEOWORKS
      necessary for the purchase of the Warrant and the performance of GEOWORKS'
      obligations hereunder has been taken. This Agreement, when executed and
      delivered by GEOWORKS, will constitute a valid and legally binding
      obligation of GEOWORKS, enforceable in accordance with its terms, except
      to the extent that enforceability may be limited by applicable bankruptcy,
      reorganization, insolvency, moratorium or other laws affecting the
      enforcement of creditors' rights generally and by general principles of
      equity.

      1.4c  PURCHASE OF WARRANT AND WARRANT SHARES ENTIRELY FOR OWN ACCOUNT. The
      Warrant and the Warrant Shares will be acquired for investment for
      GEOWORKS' own account, not as a nominee or agent, and not with a view to
      the resale or distribution of any part thereof, and GEOWORKS has no

<PAGE>   6

      present intention of selling, granting any participation in, or otherwise
      distributing the same, although it is free to formulate such an intention
      in the future after the expiration of any applicable holding period under
      the federal and state securities laws and regulations promulgated thereto.
      Any future disposition of the Warrant or the Warrant Shares will occur in
      compliance with all applicable federal and state securities laws and
      regulations.

      1.4d  INVESTMENT EXPERIENCE. GEOWORKS is an "accredited investor" as
      defined in Rule 501(a) under the Securities Act of 1933, as amended (the
      "Securities Act"). GEOWORKS is or will become prior to the Effective Date,
      aware of MYTURN's business affairs and financial condition and has been
      provided access to and has acquired sufficient information about MYTURN,
      including a review of the Compu-DAWN Commission Reports, to reach an
      informed and knowledgeable decision to acquire the Warrant. GEOWORKS has
      such business and financial experience as is required to give it the
      capacity to protect its own interests in connection with the purchase of
      the Warrant, and GEOWORKS acknowledges there is presently no public market
      for the Warrant. GEOWORKS is not a "broker" or a "dealer" as defined in
      the Exchange Act.

      1.4e  RESTRICTED AND UNRESTRICTED SECURITIES. GEOWORKS understands that
      the Warrant and the Warrant Shares are characterized as "restricted
      securities" under applicable U.S. federal and state securities laws,
      inasmuch as they are being, or will be, acquired from Compu-DAWN in a
      transaction not involving a public offering and that, pursuant to these
      laws and applicable regulations, GEOWORKS must hold the Warrant, and, upon
      the execution thereof, the Warrant Shares indefinitely unless they are
      registered with the Commission and qualified by state authorities, or an
      exemption from such registration and qualification requirements is
      available. GEOWORKS understands that the Shares, if, when, and as issued,
      are not intended to be restricted securities and, as such, its
      representations and warranties set forth above are not applicable to the
      Shares.

      1.4f  LEGENDS. GEOWORKS understands that the Warrant, the Warrant Shares,
      and the Deficient Shares and the Deficient Penalty Shares (as those terms
      are defined in Section 3.6, below) will bear a legend substantially
      similar to the following:

      THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933 OR ANY APPLICABLE STATE LAW, AND NO
      INTEREST THEREIN MAY BE SOLD, DISTRIBUTED, ASSIGNED, OFFERED, PLEDGED OR
      OTHERWISE TRANSFERRED UNLESS (a) THERE IS AN EFFECTIVE REGISTRATION
      STATEMENT UNDER SUCH ACT COVERING ANY SUCH TRANSACTION INVOLVING THESE
      SECURITIES OR (b) THE COMPANY RECEIVES AN OPINION OF LEGAL COUNSEL,
      ACCEPTABLE TO THE COMPANY, FOR THE HOLDER OF THESE SECURITIES STATING THAT
      SUCH TRANSACTION IS EXEMPT FROM REGISTRATION, OR THE COMPANY OTHERWISE
      SATISFIES ITSELF THAT SUCH TRANSACTION IS EXEMPT FROM REGISTRATION.

1.5   COVENANT OF MYTURN.

      1.5a  LISTING OF COMPU-DAWN'S SECURITIES ON THE NASDAQ STOCK MARKET
      SMALLCAP. Upon the Warrant Shares becoming publicly tradable pursuant to
      the registration requirements of applicable U.S. securities laws or
      exemptions therefrom, Compu-DAWN, or its successor, shall take all
      rea-

<PAGE>   7

      sonable action to list the Warrant Shares, the Shares, the Deficient
      Shares, and the Deficient Penalty Shares on The Nasdaq Stock Market
      SmallCap.

      Distributors of MYTURN, all such sublicenses to be in writing and subject
      to the terms, conditions and limitations of this Agreement. MYTURN and its
      sublicensees will distribute the Licensed Technology and Derivative Works
      to End-Users only under the terms of an End User license substantially in
      the forms provided as Exhibit D.

      3.4b  GEOWORKS shall grant to MYTURN the right to distribute the software
      development tools and documentation included within the Licensed
      Technology, upon mutual agreement as to commercial terms and conditions of
      the proposed distribution arrangement.

3.5   RESERVED RIGHTS.

      3.5a  MYTURN may not distribute, or authorize its Distributors to
      distribute, Licensed Technology or Derivative Works in any form that is
      not Embedded; provided, however, that MYTURN may distribute software

      3.5b  MYTURN's rights hereunder shall be subject to rights granted by
      GEOWORKS to Licensees of GEOWORKS.

      3.5c  GEOWORKS reserves to itself and its licensees the exclusive right to
      manufacture and distribute the Licensed Technology in all devices other
      than MYTURN PC Devices.

3.6   EXCLUSIVITY.

      3.6a  Subject to Section 3.5 (Reserved Rights) and Section 3.6(b)
      (Conditions of Exclusivity), and provided that MYTURN is in full
      compliance with all payment obligations, provisions, terms, and conditions
      in this Agreement, the rights granted to MYTURN in Sections 3.1
      (Reproduction) and 3.3 (Distribution) shall be conditionally granted to
      MYTURN, and not to any PC device competitors of MYTURN, during the term of
      this Agreement.

      3.6b  Conditions of Exclusivity. The rights granted to MYTURN in Sections
      3.1 (Reproduction) and 3.3 (Distribution) are conditional. If MYTURN
      timely makes all payments in accordance with their terms, including
      GEOWORKS' deferral of remedies terms, and complies with all other terms
      and conditions in this Agreement, meets all the performance requirements
      set forth hereinbelow, and timely makes all the royalty payments set forth
      in Exhibit C, MYTURN shall obtain conditional rights, subject to meeting
      said performance requirements continuously and making said royalty
      payments. With respect to royalty payments due based on units shipped
      under the performance requirements set forth below, and only such royalty
      payments, MYTURN may also maintain conditional rights by paying to
      GEOWORKS, no later than the last day of each applicable period, a cash
      amount equal to the number of units (cash equivalent) by which it is short
      of the performance requirements set forth below, multiplied by the minimum
      royalty for North American, International, and School units as set forth
      in Exhibit C. Royalties are due, payable and fully earned by GEOWORKS upon
      shipment by MYTURN.

      3.6c  Performance Requirements:

            # # #

3.7   REMEDIES.

      3.7a  MYTURN agrees to perform all obligations herein, comply with all
      terms and conditions herein, timely pay all money due GEOWORKS as
      indicated herein, and timely pay all per unit royalties for the Licensed
      Technology as indicated herein. If MYTURN defaults in respect of its
      performance of any or all of its requirements set forth in this Agreement,
      then, without the requirement of notice, GEOWORKS will be entitled to
      exercise any and all of its legal and equitable remedies, including those
      outlined in this Section 3.7.

      3.7b  In addition to all other remedies herein arising from any breach of
      any provision in this Agreement (including the Recitals), in the event
      MYTURN fails to meet any of the payment obligations, terms, or conditions
      of this Agreement, or fails to meet the shipment and/or payment
      performance requirements in this Agreement, and said failure remains
      uncured for a net total cure period of sixty (60) calendar days, then,
      without the requirement of notice, the conditional exclusive li-

<PAGE>   10

      cense to the Licensed Technology granted herein shall immediately become
      non-exclusive.

            Separately, and in addition the licenses granted herein becoming
      non-exclusive, if MYTURN fails to pay in full the Initial License Fee --
      Cash due GEOWORKS on or before March 30, 2000 (or the subsequent due dates
      set forth immediately below), or within two days of the date on which
      Compu-DAWN, or any of its affiliates or subsidiaries, shall have received
      any funds or financing from any source in excess of $3,000,000 prior to
      March 28, 2000, then, in order to continue the use of the Licensed
      Technology, MYTURN shall be obligated to deliver to GEOWORKS as separate
      consideration for its agreement to defer (i) collection action, (ii)
      termination of MYTURN's rights to the Licensed Technology and the
      Enhancements, and (iii) acquisition of all Derivative Works on an
      exclusive basis, the following:

            (i)   80,000 of the Shares on March 31, 2000, or such earlier,
                  analogous date if Compu-DAWN, or any of its affiliates or
                  subsidiaries, shall have failed to pay the Initial License Fee
                  -- Cash in full within two days of its receipt of any funds or
                  financing from any source in excess of $3,000,000 prior to
                  March 28, 2000;

            (ii)  an additional 80,000 of the Shares, if the Initial License Fee
                  -- Cash is still unpaid on April 29, 2000, which additional
                  Shares shall be delivered on April 30, 2000, or such earlier,
                  appropriate date if Compu-DAWN, or any of its affiliates or
                  subsidiaries, shall have failed to pay the Initial License Fee
                  -- Cash in full within two days of its receipt of any funds or
                  financing from any source in excess of $3,000,000 prior to
                  March 28, 2000;

            (iii) an additional 80,000 of the Shares, if the Initial License Fee
                  -- Cash is still unpaid on May 29, 2000, which additional
                  Shares shall be delivered on May 30, 2000, or such earlier,
                  appropriate date if Compu-DAWN, or any of its affiliates or
                  subsidiaries, shall have failed to pay the Initial License Fee
                  -- Cash in full within two days of its receipt of any funds or

                  March 28, 2000; and

            (iv)  an additional 80,000 of the Shares, if the Initial License Fee
                  -- Cash is still unpaid on June 29, 2000, which additional
                  Shares shall be delivered on June 30, 2000, or such earlier,
                  appropriate date if Compu-DAWN, or any of its affiliates or
                  subsidiaries, shall have failed to pay the Initial License Fee
                  -- Cash in full within two days of its receipt of any funds or
                  financing from any source in excess of $3,000,000 prior to
                  March 28, 2000.

            If any of the Shares, upon their issuance, shall not be registered
      with the Commission and unrestricted, and freely-tradable, then
      Compu-DAWN, or any successor entity, if applicable (the "Deficient
      Shares"), shall immediately issue and addition quantity of shares of its
      common stock equivalent to 10% of the number of such Deficient Shares (the
      "Deficient Penalty Shares"). In addition, all of the registration rights
      granted to GEOWORKS in respect of the Warrant Shares

<PAGE>   11

      shall also attach to the Deficient Shares and to the Deficient Penalty
      Shares.

            Notwithstanding the issuance of the Shares (and, if applicable, the
      Deficient Shares and the Deficient Penalty Shares), and separately, and in
      addition to all other remedies available to GEOWORKS, if, as of July 1,
      2000, or such earlier, appropriate date if Compu-DAWN, or any of its
      affiliates or subsidiaries, shall have failed to pay the Initial License
      Fee -- Cash in full within two days of its receipt of any funds or
      financing from any source in excess of $3,000,000 prior to March 28, 2000,
      MYTURN has failed to pay the Initial License Fee -- Cash in full,
      including interest due to GEOWORKS, then, in addition to continuing to
      remain liable to GEOWORKS for all said money, and without requirement of
      notice, all of MYTURN's rights in and to the Licensed Technology shall
      cease immediately and the Enhancements and all Derivative Works shall
      immediately become the sole property of GEOWORKS.

            Not later than January 10, 2000, and on the 10th day of each month
      thereafter, MYTURN shall deliver the source code for the Enhancements and
      all Derivative Works then extant on a CD-ROM to an escrow agent reasonably
      acceptable to Compu-DAWN and GEOWORKS for safekeeping. The terms of such
      escrow shall provide, among other items, that the escrow agent shall
      deliver such CD-ROMs to GEOWORKS at the time it is entitled thereto
      pursuant to the terms hereof, or shall deliver such CD-ROMs to MYTURN at
      the time it is entitled thereto pursuant to the terms hereof. In no event
      shall GEOWORKS be entitled to utilize such source code information except
      as permitted in accordance with the terms and conditions of this Agreement
      and pursuant to the transactions contemplated hereby.

4.    MANUFACTURERS AND OEMS. Each Manufacturer of MYTURN and each OEM of MYTURN
that is granted sublicense rights under Section 3 (GRANT OF LICENSES) must agree
in writing:

      4.1a  to accept that no ownership rights to the Licensed Technology or to
      Derivative Works are transferred to the Manufacturer or OEM;

      4.1b  to include on all copies of the Licensed Technology and Derivative
      Works, and on all related packaging, manuals and promotional materials,
      all proprietary, copyright, trade secret and other notices in accordance
      with Section 8.1 (Acknowledgment of GEOWORKS) hereof;

      4.1c  not to decompile or reverse engineer the Licensed Technology or
      Derivative Works;

      4.1d  to keep records showing the number of copies of the Licensed
      Technology and Derivative Works manufactured, and the number of copies
      distributed;

      4.1e  to furnish to MYTURN, within 30 days from the end of each calendar
      quarter, a signed statement showing the number of copies so made and the
      number of copies so distributed, and to allow MYTURN or GEOWORKS to have
      such statements examined and audited by an independent auditor to the
      extent necessary to verify such statements, subject to the audit
      conditions set forth in Section 7.7 (Audits); and

<PAGE>   12

      4.1f  to be bound by the provisions of this agreement, and to permit
      GEOWORKS to enforce such provisions against such Manufacturers, provided
      that the appointment of Manufacturers and OEMs by MYTURN shall not in any
      respect create any relationship between GEOWORKS and such persons.

5.    INTELLECTUAL PROPERTY RIGHTS.

5.1   THE LICENSED TECHNOLOGY. GEOWORKS and its licensors are and shall remain
      the sole owners of all Intellectual Property Rights in and to the Licensed
      Technology.

5.2   THE MYTURN PC DEVICES. MYTURN is and shall remain the owner of all
      Intellectual Property Rights in and to the MYTURN PC Devices (excluding
      the Licensed Technology, and excluding any Derivative Works owned by
      GEOWORKS as set forth below).

5.3   DERIVATIVE WORKS.

      5.3a  GEOWORKS shall own the Intellectual Property Rights in and to any
      Derivative Works made by GEOWORKS during the course of this Agreement.
      Derivative Works made by GEOWORKS pursuant to this Agreement at the
      request of MYTURN shall automatically be included within the licenses
      granted in Section 3 (GRANT OF LICENSES) of this Agreement. Other
      Derivative Works made by GEOWORKS during the term of this Agreement shall
      be treated as set forth in Section 6 (UPDATED AND NEW LICENSED
      TECHNOLOGY).

      5.3b  MYTURN shall conditionally own the Intellectual Property Rights in
      and to any Derivative Works made by MYTURN during the course of this
      Agreement or made for MYTURN by third parties other than GEOWORKS
      (hereafter referred to as "made by or for MYTURN").

      5.3c  MYTURN's Intellectual Property Rights in Derivative Works shall not
      extend to the underlying Licensed Technology or underlying Derivative
      Works owned by GEOWORKS, as set forth above, but only to the modifications
      thereto made by or for MYTURN.

      5.3d  GEOWORKS may independently develop and own the Intellectual Property
      Rights to Derivative Works that are functionally equivalent to those made
      by or for MYTURN, provided that it does so without copying the source code
      to any MYTURN-owned Derivative Works. For this purpose, the Parties
      understand that MYTURN may provide GEOWORKS with access to the source code
      to the MYTURN-owned Derivative Works, so that GEOWORKS may assist MYTURN
      in its development activities. The Parties agree that GEOWORKS'
      development of equivalent GEOWORKS-owned Derivative Works shall be
      considered "independent" despite such access.

      5.3e  Where the contributions of GEOWORKS and MYTURN to the creation of a
      Derivative Work are so interlinked that it is not possible to determine
      separate ownership, then each of the Parties shall have an undivided
      one-half ownership interest in any Intellectual Property Rights therein;
      provided however, that such jointly-owned Intellectual Property Rights
      shall not extend to the underlying Licensed Technology or underlying
      Derivative Works owned by either Party, as set forth above, but only to
      the modifications thereto made jointly.

<PAGE>   13

      5.3f  Each Party shall take all actions and execute all documents that are
      necessary to assign to the other its one-half ownership interest in any
      jointly-owned Intellectual Property Rights. Neither Party shall be
      required to obtain the consent of, or account to, the other Party for the
      exploitation of the rights covered by any such jointly-owned Intellectual
      Property Rights, except that neither Party shall have the authority to
      grant an exclusive license under any such rights without the prior written
      consent of the other Party.

      5.3g  For purposes of this Section 5.3 (DERIVATIVE WORKS), a Party shall
      be considered to have "made" or made a "contribution" to a Derivative Work
      by substantially participating in the design and coding of the software.
      MYTURN accepts that no jointly owned Intellectual Property Rights is
      created merely because MYTURN supplies to GEOWORKS a specification of
      features which GEOWORKS then creates.

6.    UPDATED AND NEW LICENSED TECHNOLOGY. Upon mutual agreement as to terms and
conditions, GEOWORKS may create updates and upgrades to the Licensed Technology
during the term of this Agreement. Further, the licenses granted in Section 3
(GRANT OF LICENSES) shall, at MYTURN's election, extend to all updates and
revisions to the Licensed Technology that GEOWORKS generally releases to all of
its OEM customers, if and when such updates are released by GEOWORKS.

7.    PAYMENTS.

7.1   INITIAL LICENSE FEE. MYTURN agrees to pay GEOWORKS the non-refundable
      Initial License Fee -- Cash of $541,083.56, of which $35,000 shall be paid
      upon execution of this Agreement and the balance shall be paid not later
      than the dates set forth in this Agreement, with interest accruing on the
      unpaid Initial License Fee -- Cash at the rate of 10% per annum.

      The Initial License Fee -- Cash, including interest accrued thereon, shall
      be payable in full by MYTURN to GEOWORKS not later than two days after
      Compu-DAWN, or any of its affiliates or subsidiaries, receives any funds
      or financing from any source in excess of $3,000,000 prior to March 28,
      2000. If Compu-DAWN, or any of its affiliates or subsidiaries, shall not
      have received any funds or financing from any source in excess of
      $3,000,000 prior to March 28, 2000, the Initial License Fee -- Cash, and
      interest accrued thereon, shall be payable in full not later than March
      30, 2000, subject to the deferrals by GEOWORKS of the exercise of its
      remedies in accordance with the terms of Section 3.7b, above, the Initial
      License Fee -- Cash, and interest accrued thereon, shall be payable in
      full not later than March 30, 2000.

      Compu-DAWN shall grant to GEOWORKS the Warrant for the purchase of 250,000
      shares of Compu-DAWN's Common Stock at the market price on the day this
      Agreement is executed.

      set forth in Exhibit C. Royalty payments are due and payable within thirty
      (30) days after the calendar quarter in which any MYTURN PC Device Product
      Shipment occurs.

7.3   NOT FOR RESALE UNITS. MYTURN will not incur any royalty payments (except
      for reimbursement to GEOWORKS for third-party technologies as identified
      in Exhibit C) for a limited number of promotional, "not for

<PAGE>   14

      resale" units of MYTURN PC Devices, not to exceed 20 units, provided free
      of charge to End Users or to MYTURN Distributors, or for units used by
      MYTURN solely for demonstration purposes and/or for customer support;
      provided, however, that a royalty payment will become due if and when
      MYTURN receives a payment or other compensation for any such units or uses
      such units for internal use other than as set forth in this Section.

7.4   CURRENCY. All payments under this Agreement are to be made in U.S.
      Dollars.

7.5   RECORDS. MYTURN shall maintain complete and accurate records of all MYTURN
      PC Device Product Shipments and records identifying the amount of
      royalties and other payments due hereunder.

7.6   REPORTS. No later than thirty (30) days after the end of each calendar
      quarter, MYTURN shall send to GEOWORKS a report detailing for such
      quarter:

      7.6a  The number of units of MYTURN PC Device Product Shipment, including
      a breakdown as applicable by MYTURN PC Device and Product, version and
      country; and

      7.6b  A detailed account of all royalty and other amounts due and the
      basis for calculation.

7.7   AUDITS. During the term of this Agreement and for twelve (12) months after
      the expiration or any termination of this Agreement, an independent
      third-party representative of GEOWORKS, reasonably acceptable to MYTURN,
      upon reasonable notice and during MYTURN's normal business hours, shall
      have the right to conduct an audit of the relevant portions of MYTURN's
      books of account to verify compliance with this Agreement. MYTURN shall
      immediately pay any overdue payments revealed by such audit(s), together
      with interest thereon at the rate of 1.5% per month (or the maximum
      permitted by applicable law, if less) from the due date until paid. Except
      as set forth below, such audit(s) may be conducted no more than once in
      any six-month period. GEOWORKS shall bear the costs of the audit;
      provided, however, if the audit reveals overdue payments in excess of five
      percent (5%) of the total royalty payable for any six-month period, MYTURN
      shall pay the costs of such audit and for each such audit GEOWORKS shall
      have the right to conduct another audit during the same six-month period.
      All information obtained by GEOWORKS' independent third party
      representative during any such audit shall be treated as Confidential
      Information as defined in Section 14 (Nondisclosure and Restricted Use).

7.8   INTEREST. MYTURN shall pay GEOWORKS interest at the rate of 1.5% per
      month, or the maximum rate allowed by law, whichever is less, on any
      payments that are overdue by more than thirty (30) days, which interest
      shall be applied from the date said sum was originally first due until the
      date the entire payment and applicable interest is due.

8.    ADVERTISING, TRADEMARK USAGE/PROTECTION AND PUBLICITY.

8.1   TRADEMARK, COPYRIGHT, AND PROPRIETARY MARKINGS. MYTURN acknowledges that
      GEOWORKS is the sole owner and sole worldwide licensor of GEOS and the
      Applications. MYTURN will not lay claim, or make or advertise any claim to
      ownership or licensing capacity to GEOS or the Applications in

<PAGE>   15

      any publication or communication. Any time MYTURN uses the GEOS name or
      mark it will be identified with the registered trademark and copyright
      marks, and with credit and reference to GEOWORKS as sole owner and
      licensor appearing on the same page in typeface and font no smaller than
      10 point. Any press release or presentation referring to or pertaining to
      GEOWORKS or GEOS in any way shall be sent to the office of General Counsel
      of GEOWORKS for review and prior written approval in advance of any
      distribution, use, or release. MYTURN agrees not to alter or remove any of
      GEOWORKS' proprietary notices on copies of Licensed Technology without
      GEOWORKS' prior written permission.

8.2   ACKNOWLEDGMENTS. Each Party shall be entitled to use the other Party's
      name and the name of its products in promotional literature and marketing
      materials, upon receipt of prior approval from the other Party, such
      approval not to be unreasonably withheld or delayed. Such approval may be
      given only by the office of General Counsel of GEOWORKS. Each Party shall
      promptly review (within five (5) business days) all such requests made
      under this Subsection.

8.3   PUBLIC RELATIONS. Upon first commercial launch of a MYTURN PC Device, and
      at other reasonable times upon mutual agreement of the Parties, each Party
      will create and issue a mutually agreeable press release, printed on its
      own letterhead, announcing the Parties' relationship as established by
      this Agreement.

9.    GEOWORKS' INDEMNITIES.

9.1   INDEMNITY. GEOWORKS will indemnify, defend, and hold harmless MYTURN
      against, and pay any resulting awards and settlements arising from, any
      claim, demand, suit or action to the extent it alleges that the Licensed
      Technology as supplied by GEOWORKS infringes upon any United States patent
      issued as of the Effective Date of this Agreement, (or, with respect to
      updates, as of the date that any update is supplied to MYTURN by
      GEOWORKS), or any copyright or trade secret of any third party, provided
      that (1) MYTURN promptly informs GEOWORKS in writing of any such claim,
      demand, action or suit, (2) GEOWORKS is given control over the defense
      thereof and MYTURN cooperates in the defense, at GEOWORKS' expense, and
      (3) MYTURN will not agree to the settlement of any such claim, demand,
      action or suit prior to a final judgment thereon without the prior written
      consent of GEOWORKS, which consent will not be unreasonably withheld.
      MYTURN shall have the right to select its own counsel to participate in
      any such defense, at MYTURN's expense. GEOWORKS' indemnity obligations do
      not apply to (1) modifications to the Licensed Technology specified by
      MYTURN, (2) modifications made to the Licensed Technology by anyone other
      than GEOWORKS, (3) use of a superseded version of the GEOWORKS Licensed
      Technology after release of an update by GEOWORKS in accordance with
      Section 6 hereof, (4) use of a superseded infringing version of the
      Licensed Technology by MYTURN after release of a non-infringing version by
      GEOWORKS in accordance with Section 9.2 hereof (GEOWORKS' Options), and
      (5) any use or combination of the Licensed Technology with any technology,
      software or hardware not supplied by GEOWORKS, if such alleged
      infringement would be avoided by use of the Licensed Technology alone or
      with other technology, software or hardware.

9.2   RESPONSE TO INFRINGEMENT CLAIM. If a claim, demand, suit or action
      alleging infringement is brought, or if GEOWORKS reasonably believes one
      may be brought (based upon the opinion of independent counsel), GE-

<PAGE>   16

      OWORKS shall have the option at its expense to (1) modify the Licensed
      Technology to avoid the allegation of infringement, (2) obtain for MYTURN
      a license to continue reproducing and distributing the Licensed
      Technology, or (3) if neither (1) nor (2) is reasonably practicable in
      GEOWORKS' discretion, terminate this Agreement as to the affected Licensed
      Technology, as to a portion thereof, or as to a specific MYTURN Product or
      Products, upon written notice.

9.3   LIMITATIONS. This Section 9 (GEOWORKS' INDEMNITIES) sets forth GEOWORKS'
      entire liability to MYTURN for any actual or alleged infringement or
      misappropriation of any third party's intellectual property rights arising
      out of the Licensed Technology. In no event shall GEOWORKS' aggregate
      liability to defend and indemnify under Section 9 (GEOWORKS' INDEMNITIES)
      exceed an amount equal to the lesser of (a) the total of all amounts that
      have been paid by MYTURN to GEOWORKS under this Agreement, plus the fair
      market value of any equity of MYTURN granted to GEOWORKS pursuant to this
      Agreement, or (b) two times the total of all amounts that have been paid
      by MYTURN to GEOWORKS under this Agreement, not including the value of
      such equity. The foregoing amounts and value shall be determined as of the
      date that the infringement claim is finally settled or, if there is no
      settlement, as of the date that a final decision is made by a court or
      arbitrator in the infringement action.

10.   MYTURN'S INDEMNITIES.

10.1  INDEMNITY. MYTURN and its Affiliates will defend GEOWORKS against, and pay
      any resulting awards and settlements arising from any claim, demand, suit
      or action to the extent it alleges that a MYTURN PC Device or any
      modification to the Licensed Technology made by or for MYTURN infringes
      upon any United States patent issued as of the Effective Date of this
      Agreement, or any copyright or trade secret of any third party provided
      that (1) GEOWORKS promptly informs MYTURN in writing of any such claim,
      demand, action or suit, (2) MYTURN is given control over the defense
      thereof and GEOWORKS cooperates in the defense at MYTURN's expense, and
      (3) GEOWORKS will not agree to the settlement of any such claim, demand,
      action or suit prior to a final judgment thereon without the written
      consent of MYTURN, which consent will not be unreasonably withheld.
      GEOWORKS shall have the right to select its own counsel to participate in
      any such defense at GEOWORKS' expense. MYTURN's indemnity obligations do
      not apply to (1) modifications to a MYTURN PC Device specified by
      GEOWORKS, and (2) any use or combination of a MYTURN PC Device with any
      technology, software or hardware not supplied by MYTURN, if such alleged
      infringement would be avoided by use of such MYTURN PC Device alone or
      with other technology, software or hardware.

10.2  LIMITATIONS. This Section 10 (MYTURN'S INDEMNITIES) sets forth MYTURN's
      entire liability to GEOWORKS for any actual or alleged infringement or
      misappropriation of any third party's intellectual property rights arising
      out of a MYTURN PC Device. In no event shall MYTURN's aggregate liability
      to defend and indemnify under Section 10 (MYTURN'S INDEMNITIES) exceed an
      amount equal to the lesser of (a) the total of all amounts to be paid by
      MYTURN to GEOWORKS under this Agreement, plus the fair market value of any
      equity of MYTURN granted to GEOWORKS pursuant to this Agreement, or (b)
      two times the total of all amounts to be paid by MYTURN to GEOWORKS under
      this Agreement, not including the value of such equity. The foregoing
      amounts and value shall be determined as of the date that the infringement
      claim is finally settled or, if there is no settlement,

<PAGE>   17

      as of the date that a final decision is made by a court or arbitrator in
      the infringement action.

11.   COMBINATION CLAIMS. Any infringement claim arising solely out of the use
      or combination of the Licensed Technology with any MYTURN technology or
      product shall be defended cooperatively by both Parties, and the cost of
      such defense and any settlements or liabilities shall be shared equitably
      by the Parties. If the Parties cannot agree as to the equitable
      arrangement, then the settlements or liabilities shall be shared pursuant
      to the determination by the arbitrator (or court, if the claim was filed
      in a court by a third party) of each Party's percentage of fault.

12.   WARRANTIES.

12.1  DISCLAIMER OF EXPRESS WARRANTIES. Subject to Section 9 (GEOWORKS'
      INDEMNITIES), all Licensed Technology, Third Party Technology,
      Confidential Information and other products or technologies provided by

      LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
      PARTICULAR PURPOSE, ARE HEREBY EXCLUDED.

12.3  LIMITED WARRANTY FOR THIRD PARTY TECHNOLOGY. WITH RESPECT TO ANY THIRD
      PARTY TECHNOLOGY, GEOWORKS WILL PASS THROUGH TO MYTURN ANY WARRANTY THAT

      COURSE OF DEALING, USAGE OR TRADE PRACTICE, REGARDING ANY HARDWARE,
      SOFTWARE, CONTENT OR SERVICES PURCHASED OR LICENSED BY MYTURN FROM THIRD
      PARTIES, EVEN IF SUCH ITEMS WERE SELECTED OR RECOMMENDED FOR MYTURN BY
      GEOWORKS. ALL WARRANTIES, IF ANY, ARE PROVIDED SOLELY BY THE THIRD PARTY
      PROVIDERS.

13.   TERM OF AGREEMENT AND TERMINATION.

13.1  TERM. This Agreement shall begin on the Effective Date. The initial term
      of the Agreement will expire on December 31, 2004, and may be extended by
      mutual agreement if MYTURN has met the Conditions of Exclusivity set forth
      in Section 3.5 (3.5(b)) (Conditions of Exclusivity). Thereafter, the

      provided that MYTURN meets performance requirements to be determined by
      mutual agreement.

13.2  TERMINATION FOR BREACH (LIMITED CURE PERIOD). Each Party shall have the

<PAGE>   18

13.3  BANKRUPTCY. Each Party shall have the right to terminate this Agreement
      immediately upon written notice in the event that the other Party becomes
      insolvent, files for any form of bankruptcy, makes any assignment for the
      benefit of creditors, or ceases to conduct business (other than in
      connection with an assignment permitted under Section 16.1 (Assignment)).
      Each Party acknowledges that if it is a debtor-in-possession or if a
      trustee in bankruptcy in a case under the United States Bankruptcy Code
      rejects this Agreement or any agreement supplementary hereto, the other
      Party may elect to retain its rights under this Agreement and/or any
      supplementary agreement as provided in Section 365(n) of the Bankruptcy
      Code. Upon written request of the other Party to the bankrupt Party or the
      Bankruptcy Trustee, the bankrupt Party or such Bankruptcy Trustee shall
      not interfere with the rights of the other Party as provided in this
      Agreement and any supplementary agreement.

13.4  TERMINATION FOR MYTURN BREACH (LIMITED CURE PERIOD). If the Agreement is
      terminated due to breach by MYTURN, all the following shall occur and
      apply: (1) MYTURN shall immediately discontinue the manufacture and
      distribution of MYTURN PC Devices and all use, copying, embedding and
      production of any additional copies of the Licensed Technology, and will
      cause any third parties who obtained from it the right to manufacture
      units of MYTURN PC Devices to do likewise; (2) any such termination or
      expiration shall not affect any End User's rights to use MYTURN PC Device
      units and shall further not affect the right of any non-affiliated third
      party who purchased units of MYTURN PC Devices from MYTURN to sell such
      units to its customers; (3) immediately upon termination, MYTURN shall
      return all copies of the Licensed Technology, including without limitation
      all master diskettes and tapes, and user manuals. MYTURN may retain only
      such copies of the Licensed Technology as it may reasonably require for
      its internal use in providing continued first level customer support to
      its End-User customers; (4) each Party shall destroy or return to the
      other all Confidential Information provided by the other Party, except
      that each Party may retain one copy for archival purposes only, as a
      record of the confidential disclosures made to it under this Agreement;
      (5) within thirty (30) days of such termination or expiration MYTURN shall
      pay to GEOWORKS any and all sums due under this Agreement; and (6) within
      thirty (30) days of such termination or expiration, MYTURN shall confirm
      in writing to GEOWORKS that all of the foregoing have occurred or been
      completed.

14.   NONDISCLOSURE AND RESTRICTED USE.

14.1  CONFIDENTIAL INFORMATION. In the course of performing this Agreement, each
      Party (the "Disclosing Party") may disclose to the other Party ("the
      Receiving Party") trade secrets and confidential and proprietary
      information of the Disclosing Party, clearly marked or, in the case of
      verbal communications, clearly confirmed in writing as "CONFIDENTIAL" or
      any other similar legend ("Confidential Information"). Such Confidential
      Information includes without limitation the terms and conditions of this
      Agreement, technical and/or internal specifications of the Disclosing
      Party's products, non-public marketing plans, future products and other
      non-public business information, the trade secrets and technology embodied
      in the Licensed Technology, the trade secrets and technology embodied in
      any MYTURN Product, each Party's sales data, customer lists and other
      non-public information. All Confidential Information shall remain the sole
      property of the Disclosing Party and the Receiving Party shall have no
      interest in or right to such Confi-

<PAGE>   19

      dential Information except as expressly set forth in this Agreement. Both
      Parties agree that all Confidential Information of the other Party shall
      be held in strict confidence, will not be disseminated or disclosed to any
      third party and will not be used by the Receiving Party for any purpose
      other than performing its rights under this Agreement without the express
      written consent of the Disclosing Party for three (3) years from the date
      of disclosure (five (5) years for technical information). Both Parties
      agree to use at least the degree of diligence to protect the other Party's
      Confidential Information as a reasonably prudent technology company would
      normally use to protect any of its own trade secrets and other
      confidential information. The provisions of this Section shall not apply
      to any information or materials:

      14.1a which are in the public domain at the time of disclosure to the
      Receiving Party or which thereafter enter the public domain through no
      action or inaction by the Receiving Party or its employees; or

      14.1b which the Receiving Party can establish and document were in the
      possession of, or known by, the Receiving Party prior to its receipt from
      the Disclosing Party; or

      14.1c which are rightfully disclosed to the Receiving Party by another
      person not in violation of the proprietary or other rights of the
      Disclosing Party, or any other person or entity; or

      14.1d which are shown by written record to have been independently
      developed by the Receiving Party, provided that the persons developing the
      same have not had access to the Confidential Information furnished to the
      Receiving Party by the Disclosing Party hereunder; or

      14.1e which are required to be disclosed pursuant to law, provided,
      however, that a minimum of ten (10) days written notice shall be provided
      by the Party intending to disclose in order to permit the other Party to
      take such action as it deems appropriate to prevent or limit such
      disclosure.

14.2  RESTRICTED USE. Without prejudice to the generality of the foregoing, each
      Party agrees not to use any of the Confidential Information or Licensed
      Technology of the other Party for any use or purposes except those
      expressly specified herein.

14.3  LICENSED TECHNOLOGY SOURCE CODE RESTRICTIONS.

      14.3a MYTURN acknowledges that GEOWORKS considers the Licensed Technology
      source code to be Confidential Information and to contain proprietary and
      trade secret information of GEOWORKS. MYTURN agrees not to provide,
      disclose, reproduce in any form, or give access to such source code to any
      third party or employee other than the Authorized Personnel. MYTURN agrees
      that Authorized Personnel shall be informed of and abide by the terms and
      conditions of this Agreement.

      14.3b MYTURN shall hold the source code in strict confidence. MYTURN shall
      investigate all unauthorized attempts to gain access to the source code of
      which it becomes aware, and immediately notify GEOWORKS concerning any
      breach of source code confidentiality, whether or not such breach was
      inadvertent.

<PAGE>   20

      14.3c The source code shall be placed on secure computer systems located
      at MYTURN's principal place of business. MYTURN shall implement sufficient
      security procedures to limit access to the source code to Authorized
      Personnel. The secure computer systems area or room shall be available for
      inspection by GEOWORKS.

      14.3d MYTURN agrees to take all reasonable precautions and to implement
      procedures to minimize the risk of theft or unauthorized copying of the
      source code, and to take appropriate action by instruction, agreement, or
      otherwise with the Authorized Personnel.

15.   LIMITATION OF LIABILITY. REGARDLESS OF WHETHER ANY REMEDY SET FORTH HEREIN
      FAILS OF ITS ESSENTIAL PURPOSE, NEITHER PARTY TO THIS AGREEMENT SHALL BE
      LIABLE TO THE OTHER PARTY FOR INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES
      OR THE LOSS OF ANTICIPATED PROFITS ARISING FROM ANY PERFORMANCE OR BREACH
      OF THIS AGREEMENT BY SUCH PARTY EVEN IF NOTICE IS GIVEN OF THE POSSIBILITY
      OF SUCH DAMAGES.

16.   GENERAL.

16.1  ASSIGNMENT. This Agreement may be not be assigned in whole or in part by

      control of which subsidiary shall be not less than 80% in favor of
      Compu-DAWN, without the prior written consent of GEOWORKS, which may
      withhold or delay consent in its sole, reasonable discretion. GEOWORKS may
      assign this Agreement in its sole discretion without any consent from
      MYTURN.

16.2  GOVERNING LAW. This Agreement will be governed and interpreted in
      accordance with the laws of the state of California, except for that body
      of law pertaining to conflicts of law, but excluding the Convention on
      Contracts for the International Sale of Goods. All disputes arising in
      connection with this Agreement shall, unless amicably settled by the
      parties, be finally settled by arbitration under the commercial
      arbitration rules of the American Arbitration Association by a panel of
      three (3) arbitrators appointed in accordance with such Rules. The place
      of arbitration shall be, unless otherwise agreed between the parties, the
      county in which the respondent resides and the city in which the
      respondent has its principal place of business. Judgment upon the award
      rendered may be entered in any Court having jurisdiction or application
      may be made to such Court for a judicial acceptance of the award and an
      order of enforcement, as the case may be. Notwithstanding the foregoing,
      either party may request injunctions, seizure orders, writs of attachment,
      and other extraordinary remedies from any court having jurisdiction in the
      case of an actual or threatened infringement of such party's patents,
      copyrights, trademarks, trade secrets or other intellectual property
      rights by the other party. The filing of a proceeding for such
      extraordinary remedies shall not constitute a waiver by the filing party
      of the right to compel arbitration of all demands for other remedies.

16.3  INDEPENDENT CONTRACTORS. Each Party will be deemed to have the status of
      an independent contractor towards the other Party, and nothing in this
      Agreement will be deemed to place the Parties in the relationship of
      employer-employee, principal-agent, partners or joint venturers.

<PAGE>   21

16.4  WAIVER. The failure of either Party to enforce any provision of this
      Agreement shall not be deemed a waiver of that or any other provision of
      this Agreement.

16.5  FORCE MAJEURE. Neither Party will be deemed in default of this Agreement
      to the extent that performance of its obligations is delayed or prevented
      by reason of any act of God, fire, natural disaster, accident, act of
      government, or any other cause beyond the control of such Party ("Force
      Majeure"), provided that such Party gives the other Party written notice
      thereof promptly and uses its good faith efforts to cure the breach. In
      the event of such a Force Majeure, the time for performance or cure will
      be extended for a period equal to the duration of the Force Majeure but
      not in excess of six (6) months.

16.6  NOTICES. Notices to either Party shall be in writing and shall be deemed
      delivered when served in person, one business day after being transmitted
      by fax, or two business days after being dispatched by an internationally
      recognized express courier service, and delivered to the addresses set
      forth at the beginning of this Agreement. A Party may change its address
      for purposes of receiving notices by giving notice of the change to the
      other Party.

16.7  SURVIVAL. The rights and obligations under Sections 5 (Intellectual
      Property Rights), 7 (PAYMENTS), 9 (GEOWORKS' INDEMNITIES), 10 (MYTURN'S
      INDEMNITIES), 11 (COMBINATION CLAIMS), 12.1 (Disclaimer of Express
      Warranties), 12.2 (Disclaimer Of Implied Warranties), 14 (NONDISCLOSURE
      AND RESTRICTED USE), 15 (LIMITATION OF LIABILITY), and 16 (GENERAL) shall
      survive the expiration and any termination of this Agreement.

16.8  EXPORT. MYTURN agrees that MYTURN will not knowingly export or reexport
      the Licensed Technology, directly or indirectly, to any country to the
      extent export to such country at the time of export requires an export
      license or other governmental approval, without first obtaining such
      license or approval.

VOID AFTER 5:00 P.M., JACKSONVILLE, FLORIDA TIME, ON DECEMBER 21, 2004

NEITHER THIS WARRANT NOR THE WARRANT STOCK (AS HEREINAFTER DEFINED) HAVE BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). THIS
WARRANT AND THE WARRANT STOCK MAY BE TRANSFERRED ONLY IN COMPLIANCE WITH THE
ACT. THIS LEGEND SHALL BE ENDORSED UPON ANY WARRANT ISSUED IN EXCHANGE FOR THIS
WARRANT.

                                COMPU-DAWN, INC.

             (INCORPORATED UNDER THE LAWS OF THE STATE OF DELAWARE)

                                                               December 22, 1999

      FOR VALUE RECEIVED, COMPU-DAWN, INC., a Delaware corporation (the
"Company"), hereby certifies that Geoworks, Inc. (the "Holder") is entitled,
subject to the provisions of this Warrant, to purchase from the Company up to
250,000 Common Shares of the Company at a price of Four Dollars and Fifty Cents
($4.50) per share (the "Exercise Price") during the period commencing on the
date hereof and expiring at 5:00 P.M., Jacksonville, Florida time, on December
21, 2004 (the "Exercise Period").

      The number of Common Shares to be received upon the exercise of this
Warrant may be adjusted from time to time as hereinafter set forth. The Common
Shares deliverable upon such exercise, and as adjusted from time to time, are
hereinafter sometimes referred to as "Warrant Stock".

      The Holder agrees with the Company that this Warrant is issued, and all
the rights hereunder shall be held subject to, all of the conditions,
limitations and provisions set forth herein.

      1.    EXERCISE OF WARRANT.

            1.1   Method of Exercise. This Warrant may be exercised by its
presentation and surrender to the Company at its principal office, by 5:00 P.M.,
Jacksonville, Florida time, during the Exercise Period, with the Warrant
Exercise Form attached hereto duly executed and, at the discretion of the
Holder, either (a) accompanied by payment (either in cash or by certified or
official bank check, payable to the order of the Company) of the Exercise Price
for the number of shares specified in such Warrant Exercise Form with
"Alternative No. 1" initialed on such Warrant Exercise Form by the Holder, or
(b) effectuated by a net issue exercise as provided in Section 1.2 hereof. If
this Warrant should be exercised in part only, the Company shall, upon surrender
of this Warrant for cancellation, execute and deliver a new Warrant evidencing
the rights of the Holder thereof to purchase the balance of the shares
purchasable hereunder.

            1.2   Net Issue Exercise.

<PAGE>   33

      9.1

            (a)   IN LIEU OF EXERCISING THIS WARRANT PURSUANT TO SECTION 1.1(A)
            ABOVE, THE HOLDER MAY ELECT TO RECEIVE A NUMBER OF COMMON SHARES
            EQUAL TO THE VALUE (AS DETERMINED BELOW) OF THIS WARRANT (OR THE
            PORTION THEREOF BEING CANCELED), TO THE EXTENT EXERCISABLE, BY
            SURRENDER OF THIS WARRANT AT THE PRINCIPAL OFFICE OF THE COMPANY IN
            THE SAME MANNER AS PROVIDED IN SECTION 1.1, TOGETHER WITH THE
            WARRANT EXERCISE FORM IN WHICH "ALTERNATIVE NO. 2" IS INITIALED BY
            THE HOLDER. IN SUCH EVENT, THE COMPANY SHALL ISSUE TO THE HOLDER A
            NUMBER OF COMMON SHARES COMPUTED USING THE FOLLOWING FORMULA:

        X = Y (A-B)
            -------
               A

Where    X     =      the number of Common Shares to be issued to the Holder

         Y     =      the number of Common Shares subject to this Warrant (or
                      the portion thereof being canceled)

         A     =      the fair market value of one share of the Company's common
                      stock.

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

      9.2

            (b)   FOR PURPOSES OF THIS SECTION 1.2, THE FAIR MARKET VALUE OF THE
            COMPANY'S COMMON STOCK SHALL MEAN:

9.2(a)

                  (i)   The average of the closing bid and asked prices of the
Company's common stock quoted in the over-the-counter market summary or the
closing price quoted on any exchange on which such common stock is listed,
whichever is applicable, as published in the Western Edition of The Wall Street
Journal for the ten trading days prior to the date of determination of fair
market value; or

9.2(b)

                  (ii)  If the Company's common stock is not traded
over-the-counter or on an exchange, the fair market value of such common stock
per share shall mean the price per share as determined reasonably and in good
faith by the Company's board of directors. Receipt and formal acknowledgment by
a duly authorized representative of the holder of the Common Shares issued upon
exercise of this Warrant by the Holder shall be conclusively deemed to be an
acknowledgment and acceptance of any such fair market value determination by the
Company's board of directors as the final and binding determination of such
value for purposes of this Warrant.

      2.    RESERVATION OF SHARES. The Company will at all times reserve for
issuance and delivery upon exercise of this Warrant all Common Shares or other
shares of capital stock of the Company (and other securities and property) from
time to time receivable upon exercise of this Warrant.

      3.    FRACTIONAL SHARES. The Company shall not be required to issue
certificates representing fractions of Common Shares, nor shall it be required
to issue scrip or pay cash in lieu of fractional interests, it being

<PAGE>   34

the intent of the Company and the Holder that all fractional interests shall be
eliminated.

      4.    EXCHANGE OR ASSIGNMENT OF WARRANT. This Warrant is exchangeable,
without expense, at the option of the Holder, upon presentation and surrender
hereof to the Company for other Warrants of different denominations, entitling
the Holder to purchase in the aggregate the same number of Common Shares
purchasable hereunder. Subject to the provisions of this Warrant and the receipt
by the Company of any required representations and agreements, upon surrender of
this Warrant to the Company with the Warrant Assignment Form annexed hereto duly
executed and funds sufficient to pay any transfer tax, the Company shall,
without additional charge, execute and deliver a new Warrant in the name of the
assignee named in such instrument of assignment and this Warrant shall promptly
be canceled.

      5.    RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
entitled to any rights of a shareholder of the Company, either at law or in
equity, and the rights of the Holder are limited to those expressed in this
Warrant.

      6.    ANTI-DILUTION PROVISIONS.

            6.1   ADJUSTMENTS FOR STOCK DIVIDENDS; COMBINATIONS, ETC. (a) In
case the Company shall do any of the following (an "Event"):

                  (i)   declare a dividend or other distribution on its Common
Shares payable in Common Shares of the Company,

                  (ii)  subdivide the outstanding Common Shares pursuant to a
stock split or otherwise,

                  (iii) combine the outstanding Common Shares into a smaller
number of shares pursuant to a reverse split or otherwise, or

                  (iv)  reclassify or otherwise change its Common Shares,

then the Exercise Price in effect at the time of the record date for such
dividend or other distribution or of the effective date of such subdivision,
combination, reclassification or other change shall be changed to a price
determined by dividing (a) the product of the number of Common Shares
outstanding immediately prior to such Event, multiplied by the Exercise Price in
effect immediately prior to such Event by (b) the number of Common Shares
outstanding immediately after such Event. Each such adjustment of the Exercise
Price shall be calculated to the nearest cent. No such adjustment shall be made
in an amount less than one cent ($.01), but any such amount shall be carried
forward and shall be given effect in connection with the next subsequent
adjustment. Such adjustment shall be made successively whenever any Event listed
above shall occur.

                  (b) Whenever the Exercise Price is adjusted as set forth in
Section 6.1 (whether or not the Company then or thereafter elects to issue
additional Warrants in substitution for an adjustment in the number of shares of
Warrant Stock), the number of shares of Warrant Stock specified in each Warrant
which the Holder may purchase shall be adjusted, to the nearest full share, by
multiplying such number of shares of Warrant Stock immediately prior to such
adjustment by a fraction, of which the numerator shall be the Exercise Price
immediately prior to such adjustment and the denominator shall be the Exercise
Price immediately thereafter.

<PAGE>   35

            6.2   ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION OR MERGER. In
case of any reorganization of the Company (or any other corporation, the
securities of which are at the time receivable on the exercise of this Warrant)
after the date hereof or in case after such date the Company (or any such other
corporation) shall consolidate with or merge with or into another corporation or
entity, then, and in each such case, the Holder of this Warrant upon the
exercise thereof as provided in Section l at any time after the consummation of
such reorganization, consolidation or merger, shall be entitled to receive, in
lieu of the securities and property receivable upon the exercise of this Warrant
prior to such consummation, the securities or property to which such Holder
would have been entitled upon such consummation if such Holder had exercised
this Warrant immediately prior thereto, all subject to further adjustment as
provided in Section 6.l; in each such case, the terms of this Warrant shall be
applicable to the securities or property receivable upon the exercise of this
Warrant after such consummation.

      7.    INVESTMENT REPRESENTATIONS.

            In connection with the acquisition of the Warrants by the Holder
from the Company, and the issuance of such Warrants by the Company to the
Holder, the Holder does hereby represent and warrant to the Company as follows:

            (a)   ACQUISITION FOR ACCOUNT. The Holder represents and warrants
                  that the Warrants acquired by it are being acquired for its
                  own account, for investment purposes and not with a view to
                  any distribution within the meaning of the Securities Act of
                  1933, as amended (the "Securities Act"). The Holder will not
                  sell, assign, mortgage, pledge, hypothecate, transfer or
                  otherwise dispose of any of the Warrants unless (i) a
                  registration statement under the Securities Act with respect
                  thereto is in effect and the prospectus included therein meets
                  the requirements of Section 10 of the Securities Act, or (ii)
                  the Company has received a written opinion of its counsel
                  that, after an investigation of the relevant facts, such
                  counsel is of the opinion that such proposed sale, assignment,
                  mortgage, pledge, hypothecation, transfer or disposition does
                  not require registration under the Securities Act or any state
                  securities law.

            (b)   NO REGISTRATION. The Holder understands that the issuance of
                  the Warrants is not being registered under the Securities Act
                  and the Warrants must be held indefinitely unless they are
                  subsequently registered thereunder or an exemption from such
                  registration is available.

            (c)   INVESTOR STATUS. The Holder represents and warrants further
                  that (i) it is either an "accredited investor," as such term
                  is defined in Rule 501(a) promulgated under the Securities
                  Act, or, either alone or with its purchaser representative,
                  has such knowledge and experience in financial and business
                  matters that it is capable of evaluating the merits and risks
                  of the acquisition of the Warrants; (ii) it is able to bear
                  the economic risks of an investment in the Warrants,
                  including, without limitation, the risk of the loss of part or
                  all of its investment and the inability to sell or transfer
                  the Warrants for an indefinite period

<PAGE>   36

                  of time; (iii) it has adequate financial means of providing
                  for current needs and contingencies and has no need for
                  liquidity in its investment in the Warrants; and (iv) it does
                  not have an overall commitment to investments which are not
                  readily marketable that is excessive in proportion to net
                  worth and an investment in the Warrants will not cause such
                  overall commitment to become excessive.

            (d)   REVIEW OF MATERIAL. The Holder has reviewed the Company's
                  reports, statements and information filed by the Company with
                  the Securities and Exchange Commission since January 1, 1999
                  and has been afforded the opportunity to obtain such
                  information regarding the Company as it has reasonably
                  requested to evaluate the merits and risks of the Holder's
                  investment in the Warrants. No oral or written representations
                  have been made or oral information furnished to the Holder or
                  its advisers in connection with the investment in the
                  Warrants.

      8.    RESTRICTIONS ON EXERCISE.

            8.1   INVESTMENT INTENT. Unless, prior to the exercise of the
Warrant, the issuance of the Warrant Stock has been registered with the
Securities and Exchange Commission pursuant to the Act, the notice of exercise
shall be accompanied by a representation of the Holder to the Company to the
effect that such shares are being acquired for investment and not with a view to
the distribution thereof, and such other representations and documentation as
may be required by the Company, unless in the opinion of counsel to the Company
such representations or other documentation are not necessary to comply with
such Act.

            8.2   LISTING; QUALIFICATION. The Company shall not be obligated to
deliver any shares of Warrant Stock until they have been listed on each
securities exchange or other self-regulatory body on which the Company's Common
Shares may then be listed or until there has been qualification under or
compliance with such federal or state laws, rules or regulations as the Company
may deem applicable. The Company shall use reasonable efforts to obtain such
listing, qualification and compliance.

      9.    RESTRICTIONS ON TRANSFER.

            9.1   TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933. Neither
this Warrant nor any Warrant Stock may be sold, assigned, transferred or
otherwise disposed of except as follows: (1) to a person who, in the opinion of
counsel satisfactory to the Company, is a person to whom this Warrant or the
Warrant Stock may legally be transferred without registration and without the
delivery of a current prospectus under the Act with respect thereto and then
only against receipt of an agreement of such person to comply with the
provisions of this Section 9 with respect to any resale, assignment, transfer or
other disposition of such securities; or (2) to any person upon delivery of a
prospectus then meeting the requirements of the Act relating to such securities
and the offering thereof for such sale, assignment, transfer or disposition.

            9.2   LEGEND. Subject to the terms hereof, upon exercise of this
Warrant and the issuance of the Warrant Stock, all certificates representing
such Warrant Stock shall bear on the face or reverse thereof substantially the
following legend:

<PAGE>   37

      "The Common Shares represented by this certificate have not been
      registered under the Securities Act of 1933, as amended, and may not be
      sold, offered for sale, assigned, transferred or otherwise disposed of
      unless registered pursuant to the provisions of that Act or such
      disposition is otherwise in compliance with an available exemption from
      such registration."

      10.   LOST, STOLEN OR DESTROYED WARRANTS. In the event that the Holder
notifies the Company that this Warrant has been lost, stolen or destroyed and
either (a) provides a letter, in form satisfactory to the Company, to the effect
that it will indemnify the Company from any loss incurred by it in connection
therewith, and/or (b) provides an indemnity bond in such amount as is reasonably
required by the Company, the Company having the option of electing either (a) or
(b) or both, the Company may, in its sole discretion, accept such letter and/or
indemnity bond in lieu of the surrender of this Warrant as required by Section 1
hereof.

      11.   APPLICABLE LAW. This Warrant is issued under, and shall for all
purposes be governed by and construed in accordance with, the laws of the State
of Delaware, excluding choice of law principles thereof.

            [Rest of page intentionally left blank. Signature page follows]

its behalf, in its corporate name, by its duly authorized officer, all as of the

                                   APPENDIX 2
                               REGISTRATION RIGHTS

      (a)   MYTURN Obligations.

      i.    Registration.

            A.    If at any time after the date hereof Compu-DAWN, Inc. d/b/a
                  MyTurn.com ("MYTURN") shall file with the Securities and
                  Exchange Commission (the "SEC") a registration statement (a
                  "Piggy-back Registration Statement") under the Securities Act
                  relating to an offering for its own account or the account of
                  others under the Securities Act of any of its equity
                  securities (other than on Form S-4 or Form S-8 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 stock option
                  or other employee benefit plans), MYTURN shall send to
                  GEOWORKS written notice of such determination and, if within
                  fifteen (15) days after the date of such notice, GEOWORKS
                  shall so request in writing, MYTURN shall include in such
                  Piggy-Back Registration Statement all or any part of the
                  common shares underlying the Warrants (the "Registrable
                  Securities") GEOWORKS requests to be registered, except that
                  if, in connection with any underwritten public offering, the
                  managing underwriter(s) thereof shall impose a limitation on
                  the number of Registrable Securities which may be included in
                  the Piggy-Back Registration Statement (the "Underwriter
                  Cutback") because, in such underwriter(s)' judgment, marketing
                  or other factors dictate such limitation is necessary to
                  facilitate public distribution, then MYTURN shall be obligated
                  to include in such Piggy-Back Registration Statement only such
                  limited portion of the as the underwriter shall permit
                  (limited to zero if necessary), provided however that in the
                  event of an Underwriter Cutback, MYTURN shall include the
                  Registrable Securities in such Piggyback Registration
                  Statement prior to including therein any securities issued by
                  MYTURN in a private placement in connection with that certain
                  Asset Purchase Agreement dated July 30, 1999, as amended

<PAGE>   41

                  on September 24, 1999, September 26, 1999, November 23, 1999
                  and December 22, 1999 between MYTURN, GPC Acquisition Corp.,
                  GlobalPC, Inc., Mark Bradlee and Brian Dougherty.

            B.    The provisions of Section (a)(i)(A) notwithstanding, if MYTURN
                  has not previously filed one or more Piggy-back Registration
                  Statements covering the resale of all of the Registrable
                  Securities then, if MYTURN receives a request from GEOWORKS,
                  MYTURN shall on no more than two (2) occasions in each
                  calendar year, commencing on May 15, 2000, prepare and file
                  with the SEC a registration statement (a "Mandatory
                  Registration Statement" and singly and collectively with any
                  Piggyback Registration Statement(s) sometimes referred to as
                  the "Registration Statement") covering the resale of the
                  Registrable Securities. MYTURN may register the resale of any
                  other of its securities on any such Mandatory Registration
                  Statement. MYTURN shall use reasonable best efforts to cause
                  the Mandatory Registration Statement to become effective as
                  soon as is practicable after the filing thereof, but in no
                  event later than the one hundredth and twentieth (120th) day
                  following the date of the filing thereof, provided however,
                  that in no event shall MYTURN be required to file a Mandatory
                  Registration Statement if it is undertaking an underwritten
                  public offering which has not closed, and in such case, the
                  date that MYTURN is required to file the Mandatory
                  Registration Statement hereunder shall be extended until the
                  thirtieth (30th) day after the underwritten offering is closed
                  and the distribution of the securities in such underwritten
                  public offering is complete.

            C.    If an offering in connection with which GEOWORKS is entitled
                  to registration under this Section 5(a)(i) is an underwritten
                  offering, then GEOWORKS shall, unless otherwise agreed by
                  MYTURN, offer and sell such Registrable Securities in an
                  underwritten offering using the same underwriter or
                  underwriters and on the same terms and conditions as other
                  like securities included in such underwritten offering.

      ii.   Amendments and Supplements; Maintain Effectiveness. MYTURN shall
            prepare and file with the SEC such amendments (including
            post-effective amendments) and supplements to the Registration
            Statement and the prospectus used in connection with the
            Registration Statement as may be necessary to keep the Registration
            Statement effective at all times for a period of six (6) months
            following the effective date thereof (the "Registration Period"),
            except during any Disclosure Delay Period (as defined in Section
            (a)(iii), and, during such period, comply with the provisions of the
            Securities Act with respect to the disposition of all Registrable
            Securities covered by the Registration Statement until such time as
            all of such Registrable Securities have been disposed of in
            accordance with the intended methods of disposition by GEOWORKS as
            set forth in the Registration Statement.

      iii.  Disclosure Delay Period. If, at any time prior to the expiration of
            the Registration Period, in the good faith reasonable judgment of
            MYTURN's Board of Directors, the disposition of Registrable
            Securities would require the premature disclosure of material

<PAGE>   42

            non-public information which may reasonably be expected to have an
            adverse effect on MYTURN, then MYTURN shall not be required to
            maintain the effectiveness of or amend or supplement the
            Registration Statement for a period (a "Disclosure Delay Period")
            expiring upon the earlier to occur of (A) the date on which such
            material information is disclosed to the public or ceases to be
            material or (B) subject to Section (a)(iv) hereof, up to sixty (60)
            calendar days after the date on which MYTURN provides a notice to
            GEOWORKS under Section (a)(iv) hereof stating that the failure to
            disclose such non-public information causes the prospectus included
            in the Registration Statement, as then in effect, to include an
            untrue statement of a material fact or to omit to state a material
            fact required to be stated therein or necessary to make the
            statements therein not misleading.

      iv.   Notice of Disclosure Delay Period. MYTURN will give prompt written
            notice, to each GEOWORKS of each Disclosure Delay Period. Each
            GEOWORKS agrees that, upon receipt of such notice prior to such
            GEOWORKS disposition of all such Registrable Securities will
            forthwith discontinue disposition of such Registrable Securities
            pursuant to the Registration Statement, and will not deliver any
            prospectus forming a part thereof in connection with any sale of
            such Registrable Securities until the expiration of such Disclosure
            Delay Period. Notwithstanding anything in this Appendix to the
            contrary, there shall not be more than an aggregate of One Hundred
            Twenty (120) calendar days in any twelve (12) month period during
            which MYTURN is in a Disclosure Delay Period.

      v.    Copies of Filings and Correspondence. MYTURN shall furnish to
            GEOWORKS (A) promptly after the same is prepared and publicly
            distributed, filed with the SEC, or received by MYTURN, one copy of
            the Registration Statement and any amendment thereto, each
            preliminary prospectus and prospectus and each amendment or
            supplement thereto, and each item of correspondence from the SEC or
            the staff of the SEC which comments upon or requests information
            relating to GEOWORKS and/or the Registrable Securities (including,
            without limitation, the resale and plan of distribution hereof), in
            each case relating to such Registration Statement (other than any
            portion, if any, thereof which contains information for which MYTURN
            has sought confidential treatment), (B) on the date of effectiveness
            of the Registration Statement or any amendment thereto, a notice
            stating that the Registration Statement or amendment has been
            declared effective, and (C) such number of copies of a prospectus,
            including a preliminary prospectus, and all amendments and
            supplements thereto and such other documents as GEOWORKS may
            reasonably request in order to facilitate the disposition of the
            Common Shares by GEOWORKS.

      vi.   Blue Sky. MYTURN shall use its best efforts to (A) register and
            qualify the Registrable Securities covered by the Registration
            Statement under such other securities or "blue sky" laws of such
            jurisdictions in the United States as GEOWORKS of a majority of the
            Registrable Securities reasonably request, (B) prepare and file in
            those jurisdictions such amendments (including post-effective
            amendments) and supplements to such registrations and qualifications
            as may be necessary to maintain the effectiveness thereof during the
            Registration Pe-

<PAGE>   43

            riod, (C) take such other actions as may be necessary to maintain
            such registrations and qualifications in effect at all times during
            the Registration Period, and (D) take all other actions reasonably
            necessary or advisable to qualify the Registrable Securities for
            sale in such jurisdictions; provided, however, that MYTURN shall not
            be required in connection therewith or as a condition thereto to (A)
            qualify to do business in any jurisdiction where it would not
            otherwise be required to qualify but for this Section (a)(vi), (B)
            subject itself to general taxation in any such jurisdiction, (C)
            file a general consent to service of process in any such
            jurisdiction, (D) provide any undertakings that cause MYTURN undue
            expense or burden, or (E) make any change in its charter or bylaws,
            which in each case the Board of Directors of MYTURN determines to be
            contrary to the best interests of MYTURN and its stockholders.

      vii.  Events Affecting Prospectus. As promptly as practicable after
            becoming aware of such event, MYTURN shall notify GEOWORKS of the
            happening of any event, of which MYTURN has knowledge, as a result
            of which the prospectus included in the Registration Statement, as
            then in effect, includes an untrue statement of a material fact or
            omission to state a material fact required to be stated therein or
            necessary to make the statements therein not misleading, and if such
            Registration Statement is supplemented or amended to correct such
            untrue statement or omission, to deliver such number as such
            GEOWORKS may reasonably request.

      viii. Notification of Amendment or Supplement. MYTURN shall, as promptly
            as practical after becoming aware of such event described in Section
            (a)(vii), notify GEOWORKS of the issuance of such order and the
            resolution thereof (and if such Registration Statement is
            supplemented or amended, deliver such number of copies of such
            supplement or amendment to such GEOWORKS as they may reasonably
            request).

      ix.   Review by GEOWORKS' Counsel. MYTURN shall permit a single firm of
            counsel designated by GEOWORKS holding a majority of the Registrable
            Securities to review the Registration Statement and all amendments
            and supplements thereto a reasonable period of time prior to their
            filing with the SEC.

      x.    GEOWORKS' Due Diligence; Confidentiality of MYTURN Information.
            MYTURN shall make available for inspection by (A) GEOWORKS, (B) one
            firm of attorneys and one firm of accountants or other agents
            retained by GEOWORKS (collectively, the "Inspectors") all pertinent
            financial and other records, and pertinent corporate documents and
            properties of MYTURN (collectively, the "Records"), as shall be
            reasonably deemed necessary by each Inspector to enable each
            Inspector to exercise its due diligence responsibility, and cause
            MYTURN's officers, directors and employees to supply all information
            which GEOWORKS holding a majority of the Registrable Securities may
            reasonably request for purposes of such due diligence; provided,
            however, that each Inspector shall hold in confidence and shall not
            make any disclosure (except to GEOWORKS) of any record or other
            information which MYTURN determines in good faith to be
            confidential, and of which determination the Inspector so notified,
            unless (A) the disclosure of such records is necessary to avoid or
            correct a misstatement or omission in any Registration Statement,
            (B) the release of such records is ordered pursuant to a subpoena or
            other order from a court or government body of competent
            jurisdiction, or (C) the information in

<PAGE>   44

            such records has been made generally available to the public other
            than by disclosure in violation of this or any other agreement.
            MYTURN shall not be required to disclose any confidential
            information in such records to any Inspector until and unless such
            Inspector shall have entered into a confidentiality agreements with
            MYTURN with respect thereto, substantially in the form of this
            Section (a)(x). GEOWORKS agrees that it shall, upon learning that
            disclosure of such records is sought in or by a court or
            governmental body of competent jurisdiction or through other means,
            give prompt notice to MYTURN and allow MYTURN, at its expense, to
            undertake appropriate action to prevent disclosure of, or to obtain
            a protective order for, the records deemed confidential. Nothing
            herein shall be deemed to limit GEOWORKS=s ability to sell Common
            Shares in a manner which is otherwise consistent with applicable
            laws and regulations.

      xi.   Confidentiality of GEOWORKS's Information. MYTURN shall hold in
            confidence and not make any disclosure of information concerning any
            GEOWORKS provided to MYTURN unless (A) disclosure of such
            information is necessary to comply with federal or state securities
            laws, (B) the disclosure of such information is necessary to avoid
            or correct a misstatement or omission in any Registration Statement,
            (C) the release of such information is ordered pursuant to a
            subpoena or other order from a court or governmental body of
            competent jurisdiction, (D) such information has been made generally
            available to the public other than by disclosure in violation of
            this or any other agreement, or (E) GEOWORKS consents to the form
            and content of any such disclosure. MYTURN agrees that it shall,
            upon learning that disclosure of such information concerning
            GEOWORKS is sought in or by a court or governmental body of
            competent jurisdiction or through other means, give prompt notice to
            GEOWORKS prior to making such disclosure, and allow GEOWORKS, at its
            expense, to undertake appropriate action to prevent disclosure of,
            or to obtain a protective order for, such information.

      xii.  Compliance with Laws. MYTURN shall comply with all applicable laws
            related to a Registration Statement and offering and sale of
            securities and all applicable rules and regulations of governmental
            authorities in connection therewith (including, without limitation,
            the Securities Act and the Securities Exchange Act of 1934, as
            amended, and the rules and regulations promulgated by the SEC.)

      (b)   Obligations of GEOWORKS. In connection with a registration of the
Registable Securities GEOWORKS shall have the following obligations:

      i.    GEOWORKS's Information. It shall be a condition precedent to the
            obligations of MYTURN to complete the registration pursuant to this
            Appendix that GEOWORKS shall furnish to MYTURN such information
            regarding itself, the Registrable Securities and the intended method
            of disposition of the as shall be required to effect the
            registration of such Registrable Securities and shall execute such
            documents in connection with such registration as MYTURN may
            reasonably request. At least five (5) business days prior to the
            first anticipated filing date of the Registration Statement, MYTURN
            shall notify GEOWORKS of the information MYTURN requires from
            GEOWORKS.

<PAGE>   45

      ii.   Cooperation. GEOWORKS agrees to cooperate with MYTURN as requested
            by MYTURN in connection with the preparation and filing of the
            Registration Statement hereunder, unless such GEOWORKS does not
            include any of his, hers or its Registrable Securities in the
            Registration Statement.

      iii.  Underwritten Offering. In the event GEOWORKS determines to engage
            the services of an underwriter, GEOWORKS agrees to enter into and
            perform its obligations under an underwriting agreement, in usual
            and customary form, including, without limitation, customary
            indemnification and contribution obligations, with the managing
            underwriter of such offering and take such other actions as are
            reasonably required in order to expedite or facilitate the
            disposition of the Registrable Securities.

      iv    No Disposition of Registable Securities. GEOWORKS agrees that, upon
            receipt of any notice from MYTURN of the happening of any event of
            the kind described in Sections (a)(vii) or (a)(viii), GEOWORKS will
            immediately discontinue disposition of Registrable Securities
            pursuant to the Registration Statement covering the resale of such
            Registrable Securities until GEOWORKS's receipt of the copies of the
            supplemented or amended prospectus contemplated by Sections (a)(vii)
            or (a)(viii) and, if so directed by MYTURN, GEOWORKS shall deliver
            to MYTURN or destroy (and deliver to MYTURN a certificate of
            destruction) all copies in possession, of the prospectus covering
            such Registrable Securities current at the time of receipt of such
            notice.

      v.    Method of Underwritten Distribution. Each GEOWORKS may not
            participate in any underwritten distribution of the Registrable
            Securities unless GEOWORKS (A) agrees to sell the Registrable
            Securities on the basis provided in any underwriting arrangements in
            usual and customary form entered into by MYTURN, (B) completes, in a
            manner reasonably acceptable to MYTURN, and executes all
            questionnaires, powers of attorney, indemnities, underwriting
            agreements and other documents reasonably required under the terms
            of such underwriting arrangements, and (C) agrees to pay its pro
            rata share of all underwriting discounts and commissions and any
            expenses in excess of those payable by MYTURN pursuant to this
            Appendix (c) below.

      (c)   Expenses of Registration. All reasonable expenses, other than
underwriting discounts and commissions, incurred in connection with
registrations, filings or qualifications, relating to (A) two (2) Piggyback
Registration Statements, and (B) two (2) Mandatory Registration Statements per
calendar year, pursuant to this Appendix, except that if a portion of the
Registrable Securities are not permitted to be included in two (2) Piggyback
Registration Statements by an underwriter as provided in Section (a)(i), then
relating to the least number of Piggyback Registration Statements which will
cover the resale of all the Registrable Securities, including all registration,
listing and qualifications fees, printers and accounting fees, the fees and
disbursements of counsel for MYTURN hereof, shall be borne by MYTURN.

      (d)   Indemnification. In the event any Registrable Securities are
included for resale in a Registration Statement under this Agreement:

<PAGE>   46

      i.    Compu-DAWN Indemnification. To the extent permitted by law,
            Compu-DAWN will indemnify, hold harmless and defend (A) GEOWORKS and
            (B) the directors, officers, partners, members, employees, agents
            and each person who controls GEOWORKS within the meaning of Section
            15 of the Securities Act or Section 20 of the Exchange Act, if any,
            (each, an "Indemnified Person"), against any joint or several
            losses, claims, damages, liabilities or expenses (collectively,
            together with actions, proceedings or inquiries by any regulatory or
            self-regulatory organization, whether commenced or threatened, in
            respect thereof, "Claims") to which any of them may become subject
            insofar as such Claims arise out of or are based upon: (A) any
            untrue statement or alleged untrue statement of a material fact in a
            Registration Statement or the omission or alleged omission to state
            therein a material fact required to be stated or necessary to make
            the statements therein not misleading, (B) any untrue statement or
            alleged untrue statement of a material fact contained in any
            preliminary prospectus if used prior to the effective date of such
            Registration Statement, or contained in the final prospectus (as
            amended or supplemented, if MYTURN files any amendment thereof or
            supplement thereto with the SEC) or the omission or alleged omission
            to state therein any material fact necessary to make the statements
            made therein, in light of the circumstances under which the
            statements therein were made, not misleading, or (C) any violation
            or alleged violation by MYTURN of the Securities Act, the Exchange
            Act, any other applicable securities law, including, without
            limitation, any state securities law, or any rule or regulation
            thereunder relating to the offer or sale of the Common Shares (the
            matters in the foregoing clauses (A) through (C) being,
            collectively, "Violations"). Subject to the restrictions set forth
            in Section (d)(iii) with respect to the number of legal counsel,
            MYTURN shall reimburse GEOWORKS and each other Indemnified Person,
            promptly as such expenses are incurred and are due and payable, for
            any reasonable legal fees or other reasonable expenses incurred by
            them in connection with investigating or defending any such Claim.
            Notwithstanding anything to the contrary contained herein, the
            indemnification agreement contained in this Section (d)(i): (A)
            shall not apply to a Claim arising out of or based upon a Violation
            which occurs in reliance upon and in conformity with information
            furnished in writing to MYTURN by such Indemnified Person expressly
            for use in the Registration Statement or any such amendment thereof
            or supplement thereto; (B) shall not apply to amounts paid in
            settlement of any Claim if such settlement is effected without the
            prior written consent of MYTURN; and (C) with respect to any
            preliminary prospectus, shall not inure to the benefit of any
            Indemnified Person if the untrue statement or omission of material
            fact contained in the preliminary prospectus was corrected on a
            timely basis in the prospectus, as then amended or supplemented, if
            such corrected prospectus was timely made available by MYTURN
            pursuant to Section (a)(v) hereof, and the Indemnified Person was
            promptly advised in writing not to use the incorrect prospectus
            prior to the use giving rise to a Violation and such Indemnified
            Person, notwithstanding such advice, used it. Such indemnity shall
            remain in full force and effect regardless of any investigation made
            by or on behalf of the Indemnified Person and shall survive the
            transfer of the Registrable Securities by GEOWORKS.

<PAGE>   47

      ii.   GEOWORKS Indemnification. In connection with any Registration
            Statement in which GEOWORKS is participating, GEOWORKS agrees to
            indemnify, hold harmless and defend, to the same extent and in the
            same manner set forth in Section (d)(i), MYTURN, each of its
            directors, each of its officers who signs the Registration
            Statement, its employees, agents and each person, if any, who
            controls MYTURN within the meaning of Section 15 of the Securities
            Act or Section 20 of the Exchange Act, and any other stockholder
            selling securities pursuant to the Registration Statement or any of
            its directors or officers or any person who controls such
            stockholder within the meaning of the Securities Act or the Exchange
            Act (collectively and together with an Indemnified Person, an
            "Indemnified Party"), against any Claim to which any of them may
            become subject, under the Securities Act, the Exchange Act or
            otherwise, insofar as such Claim arises out of or is based upon any
            Violation, in each case to the extent (and only to the extent) that
            such Violation occurs in reliance upon and in conformity with
            written information furnished to MYTURN by GEOWORKS expressly for
            use in connection with such Registration Statement, and subject to
            Section (d)(iii), GEOWORKS will reimburse any legal or other
            expenses (promptly as such expenses are incurred and are due and
            payable) reasonably incurred by them in connection with
            investigating or defending any such Claim; provided, however, that
            the indemnity agreement contained in this Section (d)(ii) shall not
            apply to amounts paid in settlement of any Claim if such settlement
            is effected without the prior written consent of GEOWORKS, which
            consent shall not be unreasonably withheld. Such indemnity shall
            remain in full force and effect regardless of any investigation made
            by or on behalf of such Indemnified Party and shall survive the
            transfer of the Registrable Securities by GEOWORKS.

      iii.  Procedure. Promptly after receipt by an Indemnified Person or
            Indemnified Party under this Section (d) of notice of the
            commencement of any action (including any governmental action), such
            Indemnified Person or Indemnified Party shall, if a Claim in respect
            thereof is to made against any indemnifying party under this Section
            (d), deliver to the indemnifying party a written notice of the
            commencement thereof, and the indemnifying party shall have the
            right to participate in, and, to the extent the indemnifying party
            so desires, to assume control of the defense thereof with counsel
            mutually satisfactory to the indemnifying party and the Indemnified
            Person or the Indemnified Party, as the case may be; provided,
            however, that such indemnifying party shall not be entitled to
            assume such defense and an Indemnified Person or Indemnified Party
            shall have the right to retain its own counsel with the reasonable
            fees and expenses to be paid by the indemnifying party, if, in the
            reasonable opinion of counsel retained by the indemnifying party,
            the representation by such counsel of the Indemnified Person or
            Indemnified Party and the indemnifying party would be inappropriate
            due to actual or potential conflicts of interest between such
            Indemnified Person or Indemnified Party and any other party
            represented by such counsel in such proceeding or the actual or
            potential defendants in, or targets of, any such action include both
            the Indemnified Person or the Indemnified Party and the indemnifying
            party and any such Indemnified Person or Indemnified Party
            reasonably determines that there may be legal defenses available to
            such Indemnified Person or Indemnified Party which are different
            from or in addition to those available to such indemnifying party.
            The indemni-

<PAGE>   48

            fying party shall pay for only one separate legal counsel for the
            Indemnified Persons or the Indemnified Parties, as applicable, and
            such legal counsel shall be selected by GEOWORKS, if GEOWORKS or any
            Indemnified Person is entitled to indemnification hereunder, or by
            MYTURN, if MYTURN or an Indemnified Party is entitled to
            indemnification hereunder, as applicable. The failure to deliver
            written notice to the indemnifying party within a reasonable time of
            the commencement of any such action shall not relieve such
            indemnifying party of any liability to the Indemnified Person or
            Indemnified Party under this Section (d), except to the extent that
            the indemnifying party is actually prejudiced in its ability to
            defend such action. The indemnification required by this Section (d)
            shall be made by periodic payments of the amount thereof during the
            course of the investigation or defense, as such expense, loss,
            damage or liability is incurred and is due and payable.

      (e)   Contribution. To the extent any indemnification by an indemnifying
party is prohibited or limited by law, the indemnifying party agrees to make the
maximum contribution with respect to any amounts for which it would otherwise be
liable under Section (d) to the fullest extent permitted by law; provided,
however, that no contribution shall be made under circumstances where the
indemnifying party would not have been liable for indemnification under the
fault standards set forth in Section (d).

      (f)   Exemption from Registration. The provisions of Section (a) through
(e) notwithstanding, MYTURN shall have no obligation to register the resale of
the Registrable Securities to the extent the Registrable Securities may be
resold without registration without violating Section 5 of the Securities Act of
1933, as amended (the "Securities Act") pursuant to Rule 144 promulgated
thereunder or any other exemption or exception from registration under the
Securities Act.
