                shall not at any time acquire any rights in the Trademarks by
                virtue of any use it may make of the Trademarks. SDTI shall not
                during the term of this Agreement, or thereafter, attack the
                title or any rights of VeriSign in and to the Trademarks or
                attack the validity of the Trademarks. SDTI shall not register
                in any country any name or mark resembling or confusingly
                similar to any of the Trademarks.

           (c)  QUALITY STANDARDS. SDTI shall use the Trademarks in accordance
                with VeriSign's trademark usage guidelines specified in Exhibit
                G, as amended by VeriSign from time to time and agreed to by
                SDTI in writing. Upon VeriSign's request, SDTI shall furnish to
                VeriSign free of cost a reasonable number of each printed item
                of advertising, packaging, or other promotional material bearing
                the Trademarks so that VeriSign may monitor SDTI's compliance
                with the trademark usage guidelines set forth in Exhibit G, as
                amended by VeriSign from time to time. If any of VeriSign's
                Trademarks are to be used in conjunction with SDTI's or another
                party's trademarks, on or in relation to the Product or
                Developed Technology, then VeriSign's Trademarks shall be
                presented legibly, but nevertheless separated from the other, so
                that each appears to be a trademark in its own right, distinct
                from the other mark.

           Corrections to the Developed Technology. VeriSign shall provide all
           assistance necessary for SDTI fully to test and evaluate the
           Developed Technology and each Deliverable to determine whether it
           substantially conforms to the Specifications, including the
           Acceptance Criteria.

     6.4   SCHEDULE CHANGES. In the event VeriSign determines that a particular
           Milestone will likely be missed, it promptly shall give notice to
           SDTI setting forth in reasonable detail the reason for the
           anticipated delay, any corrective measures VeriSign intends to
           undertake and the estimated revised Milestone.


     7.1   SUPPORT AND INFORMATION. SDTI will provide any engineering support,
           technical training and other resources, including SDTI Pre-Existing
           Technology, reasonably requested by VeriSign to assist VeriSign with
           a Statement of Work ("RESOURCES"). SDTI shall not be obligated to
           provide specific Resources or specific levels of any Resource unless
           agreed in writing by SDTI.

     7.2   DEVELOPMENT EQUIPMENT. SDTI shall provide to VeriSign the Development
           Equipment listed in Exhibit A. The Development Equipment shall be
           shipped to VeriSign freight prepaid.

     7.3   SDTI UPDATES. SDTI may, in its sole discretion, update the SDTI Pre-
           Existing Technology, if any, provided to VeriSign if a new release
           becomes available during the Development Period, subject to
           VeriSign's written agreement to any modification to the
           Specifications necessitated by such new release.

     7.4   CHANGES. If, at any time, SDTI desires to modify the Specifications
           or the Statement of Work, SDTISDTI shall present a written request to
           VeriSign describing such modifications using VeriSign's standard
           Project Change Request Form (each such request is a "CHANGE ORDER"),
           which VeriSign may approve in its sole discretion. VeriSign will
           promptly review each such Change Order and determine, in VeriSign's
           reasonable discretion, whether such Change Order can be accomplished
           by VeriSign, and whether the performance of such Change Order will
           increase the costs and/or delay the original schedule for creating
           the Deliverables. If the parties agree to the Change Order (including
           without limitation any such increased costs and/or delays estimated
           by VeriSign), the Change Order will be deemed to amend and become
           part of the Statement of Work and VeriSign will perform the
           Consulting Services in accordance with such amended Statement of

           for so long as VeriSign's CA services and products are superior or
           competitive (at a minimum, in terms of pricing, performance and
           features) with similar products available in the market, as
           determined by SDTI in its sole discretion, SDTI will purchase and use
           VeriSign's CA products and services for its internal use only.

     7.6   To the extent SDTI personnel are provided or take action at
           VeriSign's site pursuant to this Agreement, such personnel shall be
           provided solely at SDTI's cost, and upon VeriSign's reasonable
           request, SDTI shall provide evidence of satisfaction of all state and
           federal employment laws and worker compensation requirements in
           connection with such personnel. Such personnel shall, at VeriSign's
           reasonable request, execute confidentiality agreements containing
           terms and conditions substantially similar to those in Section 10,
           and shall agree to 

           abide by all reasonable VeriSign visitor regulations. SDTI
           understands that VeriSign operates a secure facility and that there
           are portions of such facility that SDTI's personnel will not be
           permitted to enter unless entry to such facility is necessary in
           order to allow SDTI to exercise its rights hereunder. In the event
           that VeriSign determines that any SDTI personnel has breached a
           VeriSign visitor regulation, SDTI shall, upon receipt of notice from
           VeriSign, immediately cause such person to be removed from VeriSign's
           facility and provide a replacement.


           Unless otherwise stated in the Statement of Work, SDTI shall advise
           VeriSign in writing within forty five (45) days of receipt of the
           completed Developed Technology for testing or evaluation whether SDTI
           accepts or rejects such Developed Technology in accordance with the
           Acceptance Criteria. In the event that SDTI does not respond in
           writing within such forty five (45) day period, then the Developed
           Technology shall be deemed accepted. If SDTI rejects the Developed
           Technology, then SDTI shall provide to VeriSign a written statement
           of the reasons for such rejection. Upon rejection, VeriSign shall
           prepare an Error Correction within twenty (20) business days and
           resubmit such Developed Technology to SDTI for evaluation pursuant to
           this Section. In the event the Developed Technology still fails to
           conform to the Acceptance Criteria after two (2) attempts to correct
           and resubmit the Developed Technology, the matter shall be escalated
           to the respective management of the parties for resolution. If the
           parties cannot reach an agreement in good faith after such executive
           escalation, either party may pursue whatever remedies it may have
           under this Agreement, at law or in equity.

     9.1   LICENSE FEE. SDTI shall make the nonrefundable license payments to
           VeriSign in accordance with Exhibit E attached hereto. Additional

     9.3   PAYMENT TERMS. SDTI will make all initial payments to VeriSign when
           specified in Exhibit E. SDTI will make all ongoing payments to
           VeriSign due under Exhibit E within thirty (30) days after receipt of
           VeriSign's invoice, unless otherwise set forth in a SOW. Payments
           made under this Agreement after their due date will incur interest at
           a rate equal to 1.5% per month or the highest rate permitted by
           applicable law, whichever is lower.

     9.4   TAXES. All amounts payable under this Agreement are exclusive of all
           sales, use, value-added, withholding, and other taxes and duties.

           on no less than 30 days' prior written notice and no more than once
           annually, VeriSign may request that an independent certified public
           accountant audit the applicable records during regular business hours
           at SDTI's offices to verify statements rendered hereunder. VeriSign
           shall bear the expenses of any such audit; provided that if such
           audit reveals that royalties paid by SDTI for any period are less

           than 95% of what should have been paid by SDTI, on VeriSign's
           request, SDTI shall pay the costs of such audit in addition to
           royalties then due and owing to VeriSign.


     10.1  CONFIDENTIAL INFORMATION. VeriSign and SDTI agree and acknowledge
           that in order to further the performance of this Agreement, they will
           be required to disclose to each other certain confidential
           information which will be identified as such in writing or, if
           disclosed orally, will be reduced to writing within thirty (30) days
           thereafter ("Confidential Information"). The Developed Technology
           will be regarded as Confidential Information whether or not it is
           identified in writing as "Confidential."

     10.2  PROTECTION OF CONFIDENTIAL INFORMATION. The receiving party agrees to
           protect the confidentiality of the disclosing party's Confidential

           with respect to its own similar proprietary information, including
           without limitation agreeing:

           (a)  Not to disclose or otherwise permit any other person or entity
           access to, in any manner, the Confidential Information or any part
           thereof in any form whatsoever, except that such disclosure or access
           shall be permitted to an employee, agent or contractor of the
           receiving party requiring access to the Confidential Information in
           the course of his or her engagement in connection with this Agreement
           and who has signed and agreement obligating the employee, agent or
           contractor to maintain the confidentiality of the confidential
           information of third parties in the receiving party's possession;

           (b)  To notify the disclosing party promptly and in writing of the
           circumstances surrounding any suspected possession, use or knowledge
           of the Confidential Information or any part thereof at any location
           or by any person or entity other than those authorized by this
           Agreement; and

           (c)  Not to use the Confidential Information for any purpose other
           than as explicitly set forth herein.

           party with respect to information or data, whether or not identical
           or similar to that contained in the Confidential Information, if such
           information or data: (a) was rightfully possessed by the receiving
           party before its received from the disclosing party; (b) is
           independently developed by the receiving part without reference to
           the disclosing party's information or data; (c) is subsequently
           furnished to the receiving party by a third party not under any
           obligation of confidentiality with respect to such information or
           data, and without restrictions on use or disclosure; (d) is or
           becomes available to the general public otherwise than through any

           dissemination of any Confidential Information provided hereunder may
           diminish substantially the value of such materials and may
           irreparably harm the disclosing party, if a receiving party breaches
           the provisions of this Section 10, the disclosing party shall,
           without limiting its other rights or remedies, be entitled to
           equitable relief, including but not limited to injunctive relief.

           Confidential Information of the other but only to the extent and
           insofar as reasonably required in connection with the performance of
           such party's obligations under this Agreement; provided that 

           all such Contractors shall be required by the applicable party to
           execute a written agreement: (a) sufficient to secure compliance by
           the Contractors with such party's obligations of confidentiality
           concerning Confidential Information set forth in Section 10; and (b)

           omissions of SDTI in connection with their activities under this
           Agreement. As a condition to such defense and indemnification,
