                Technology, or any party thereof. No attempt hereafter will be
                made by Owner, or with Owner's authorization, to encumber,

        binding and that a judgment may be entered on such arbitration award in
        any court of competent jurisdiction. The parties agree that no damages
        may be sought or awarded in any such arbitration other than specifically

        whatsoever shall Owner have any right to injunctive relief or to enjoin,
        restrain or otherwise interfere with the production, distribution or
        other exploitation of any production produced hereunder, or to
        terminate, cancel or rescind this Agreement or the grant of any rights
        hereunder, for any reason whatsoever, including, without limitation, any
        claimed failure or breach on Datalink.net's part.

7.      Indemnification. Owner agrees to defend, indemnify and otherwise hold
        Datalink.net and its employees, officers, directors, agents,
        representatives, successors, licensees and assigns free and harmless

        reasonable attorneys' fees and costs whether or not litigation is
        commenced) arising out of or resulting from any breach or alleged breach

        representations and warranties of Owner.

8.      Assignment. Datalink.net may not assign or transfer this Agreement and

        without the prior consent of Owner (which consent shall not be
        unreasonably withheld), and this Agreement shall inure to the benefit of



                                                                               2
<PAGE>   3

        Datalink.net's successors and assigns and shall be binding upon Owner's
        successors and assigns. This Agreement is personal to Owner and may not
        be assigned or transferred.

9.      Successors and Assigns. It is agreed that each and every covenant,
        agreement, term and condition herein contained will extend to and be
        binding upon the respective successors, heirs, administrators, executors
        and assigns of the parties hereto.

10.     Invalidity of Provisions. If any term or provision of this Option or the
        application thereof to any person or circumstance shall, to any extent,
        be invalid or unenforceable, the remainder of this Option, or the
        application of such term or provision to persons or circumstances other
        than those as to which it is held invalid or unenforceable, shall not be
        affected thereby.

11.     Interpretation. This Option shall be governed by and interpreted in
        accordance with the laws of the State of California.

12.     Limitation of Liability. The liability of Owner hereunder shall be
        limited to the interest now held by Owner in the Technology (pursuant to
        the Purchase Agreement). This Option has been agreed to by Owner and
        Datalink.net with the expectation that the Purchase Agreement, the
        Technology license and the Note will run their natural course without
        defaults. Except as expressly provided in the next sentence,
        Datalink.net's rights hereunder shall be to pursue Owner's interest in
        the Technology and Datalink.net shall have no recourse personally
        against Owner to enforce this Option. Notwithstanding the foregoing,
        however, Owner warrants to Datalink.net that Owner will take no action
        without the written consent of Datalink.net which would result in
        further encumbering Owner's interest in the Technology.

13.     Counterparts. This Option may be executed in one or more counterparts,
        all of which are to be considered one and the same agreement, and shall
        become effective when one or more counterparts have been signed by all
        of the parties hereto and delivered to the other party.

14.     Miscellaneous. Owner agrees to execute, acknowledge and deliver to
        Datalink.net, in a form approved by Datalink.net, any additional
        documents or instruments which Datalink.net may deem necessary to fully
        effectuate and carry out the intent and purposes of this Agreement. The
        parties may enter into a more formal contract incorporating the terms
        set forth in this Agreement
