      This agreement ("Agreement") is made and entered into in between DynTek
Services, Inc., a Delaware corporation with offices at 18881 Von Karman Avenue,
Suite 250, Irvine, CA 92612 (hereinafter referred to as "DynTek") and Child
Support Technologies, Inc., a Mississippi corporation, having offices located at
210 East Capitol Street, Suite 2000, Jackson, Mississippi 39201 ("CST"), as of
March 1, 2004 (the "Effective Date").

      WHEREAS, DynTek owns the ProductivIT product; and

      WHEREAS, CST has been granted licenses to ProductivIT under separate
agreement styled ProductivIT Sale Agreement of even date herewith (the "Sale
Agreement"); and

      WHEREAS, the parties wish to memorialize the terms and conditions under
which CST will receive maintenance, support and ongoing portal access relating
to ProductivIT;

      NOW, THEREFORE, the parties agree as follows:

Terms and Conditions

1.    Definitions. The definitions herein shall apply to any defined term,
whenever it appears in this document, with or without quotation marks and/or
capitalization, unless such definition would result in absurdity or contradict
the intent of this document, in which case the term shall be defined by the
plain meaning of the words.

      a.    ProductivIT shall mean the ProductivITTM products.

      b.    Discontinued Products shall mean obsolete Products that DynTek no
            longer develops or supports. Discontinued Products shall not include
            previous versions of products that have been upgraded.

      c.    Third Party Clients shall mean those persons or organizations
            receiving services from CST or its affiliates not for resale and
            shall be interchangeable with Retail Customers.

      d.    Services shall mean the services to be provided by DynTek described
            in Section 2.

All capitalized terms used herein and not otherwise defined shall have the
meanings ascribed thereto in the Sale Agreement.

2.    Services and Pricing. For and in consideration of the license fee being
paid to DynTek by CST under the Sale Agreement, $ 150,000 is allocated for CST
to receive standard ProductiveIT maintenance and support for ProductiveIT
licenses issued under the Sale Agreement (the "Services"). Support and
maintenance includes, but is not limited to, ProductivIT localization for up to
four agents, ongoing portal access and support of future versions of Microsoft
Desktop Operating Systems. The fees being paid under the Sale Agreement are all
inclusive. No additional amounts will be charged for taxes applicable to the
Services, including, but not limited to federal, state or local taxes, or sales,
use,

<PAGE>
                                      -2-

excise, ad valorem or other taxes or duties. DynTek is solely responsible
for the payment of all such taxes when applicable and shall indemnify and hold
CST harmless from the same.

3.    Product Changes. DynTek shall have no obligation to support any
Discontinued Product for longer than one year from the date it becomes
discontinued.

4.    Relationship of Parties. The parties agree that this Agreement is between
merchants and has been negotiated at arms length. No agency, partnership or
joint venture is intended or created hereby except to the extent that CST is
acting as an independent merchant, receiving DynTek's Services in the normal
flow of commerce. Neither party shall have any authority to bind the other
except as specifically provided herein. Nothing in this Agreement shall be
construed to (i) give either party the power to direct and control the
day-to-day activities of the other, (ii) constitute the parties as partners,
joint venturers, co-owners or otherwise as participants in a joint or common
undertaking, or (iii) allow either party to create or assume any obligation on
behalf of the other party for any purpose whatsoever. All financial obligations
associated with a party's business are the sole responsibility of such party.
All sales and other agreements between CST and its customers are CST's exclusive
responsibility and shall have no effect on CST's obligations under this
Agreement. Each party shall be solely responsible for, and shall defend, upon
the other party's request and approval of counsel, indemnify and hold the other
party free and harmless from any and all claims, damages or lawsuits (including
such other party's reasonable attorneys' fees) arising out of the acts of a
party, its employees or its agents, which legal and other proceedings for which
indemnification is sought shall be conducted with counsel reasonably
satisfactory to the indemnified party.

5.    Proprietary Rights and Confidentiality

      a. Confidentiality. Each party agrees that at all times during and after
      the term of this Agreement it will not use in any way for its own account
      or the account of any third party, nor disclose to any third party any of
      the other party's' product sales and marketing information, customer lists
      and pricing information, or other confidential information of the other
      party, and shall take every reasonable precaution to protect the
      confidentiality of such information. CST shall not publish any technical
      description of ProductiivIT or beyond the description published by DynTek
      without the express, written consent of DynTek.

      b. Indemnification. DynTek will defend at its expense any action brought
      against CST and/or any employee, partner, customer, agent and/or affiliate
      of CST, including any parent corporation of CST, to the extent based upon
      the claim that a ProductivIT or the Services, or any part thereof,
      infringes any duly issued United States patent, copyright or other
      intellectual property right of a third party ("intellectual property
      right") and shall pay any settlements or judgments to the extent based
      thereon; provided DynTek shall have had sole control of the defense of any
      such action or settlement negotiations with respect thereto, and no
      settlement of any such action occurred without the consent of DynTek; and
      provided further that CST notifies DynTek promptly in writing of such
      claim, suit or proceeding and, at DynTek's expense (except the value of
      time of CST's employees), gives DynTek adequate information and otherwise
      cooperates with DynTek.

<PAGE>
                                      -3-

      If ProductivIT becomes or the Services become, or in the opinion of
      DynTek, may become, subject to any claim of infringement of any
      intellectual property right, DynTek may, at its option: (i) procure for
      CST the right to use ProductivIT or Services; (ii) replace or modify the
      ProductivIT or Services, or any part thereof to make it non-infringing; or
      (iii) remove ProductivIT or cease providing the Services, or part thereof,
      and refund the aggregate payments paid therefor to DynTek under the Sale
      Agreement less a reasonable sum for the benefits of CST's prior use of
      ProductivIT.

      c. Entire Liability. The foregoing provisions of this section state the
      entire liability and obligation of DynTek and the exclusive remedy of CST
      and its customers with respect to the alleged infringement of any
      intellectual property right by ProductivIT or the Services or any part
      thereof.

6.    Limitation of Liability. DynTek's liability arising out of this Agreement
(other than DynTek's liability and obligations under Section 5 hereof which
shall not be subject to the limitations of this Section 6), the termination
thereof, and/or provision of Services shall be limited to the amount paid by CST
for the licenses supported hereunder. In no event shall DynTek be liable for
cost of procurement of substitute goods by anyone. Except as set forth in
Section 5, in no event shall DynTek be liable to CST or any other entity for any
special, consequential, incidental or other damages, however caused, whether for
breach of contract or otherwise, and whether or not CST has been advised of the
possibility of such damage. This limitation shall apply notwithstanding any
failure of essential purpose of any limited remedy provided herein.

8.    Term and Termination.

      a. This Agreement shall be effective upon its Effective Date and shall
      continue for the duration of the licenses granted under the Sale
      Agreement.

      b. Termination for Cause. If either party defaults in the performance of
      any provision of this Agreement for Cause (other than a Payment Default
      which falls within the definition of Cause, which shall only have a ten
      (10) day cure period following notice), then the non-defaulting party may
      give notice to the defaulting party that if the default is not cured
      within thirty (30) days the Agreement will be terminated. If the
      non-defaulting party gives such notice and the default is not cured during
      the thirty (30) day period, the Agreement shall terminate immediately upon
      written notice by the non-defaulting party. For purposes of this
      Agreement, "Cause" is an event of default as defined in Section 8.c.(1)and
      (2) below.

      c. This Agreement may be terminated by the non-defaulting party if any of
      the following events of default occur: (1) if a party materially fails to
      perform or comply with this Agreement or any provision hereof (including
      but not limited to any failure to make a payment when due as provided in
      this Agreement); (2) if either party fails to strictly comply with the
      provisions of Section 5.a. (Confidentiality); (3) if a party becomes
      insolvent or admits in writing its inability to pay its debts as they
      mature, or makes an assignment for the benefit of creditors; (4) if a
      petition under any foreign, state, or United States bankruptcy act,
      receivership statute, or the like, as they now exist, or as they may be
      amended, is filed by a party; or (5) if such a petition is filed by any
      third party, or an application for a receiver is made by anyone and such
      petition or application is not dismissed within sixty (60) days.

<PAGE>
                                      -4-

      Termination by the non-defaulting party under subprovisions (3) through
      (5) above may be effected immediately upon occurrence of such events.

      d. Obligations on Termination. Within ten (10) days after termination of
      this Agreement by DynTek due to a default of CST, CST shall cease and
      desist all use of the Software and Documentation and shall return to
      DynTek all full or partial copies of the Software and Documentation in
      Licensee's possession or under its control.

      e. Portal Support. In event DynTek ceases to conduct business or is unable
      to provide ongoing access to the portal due to financial constraints or
      other factors, CST is hereby granted the perpetual right to receive, use
      and operate the portal server application and intellectual property rights
      as necessary for the limited purpose of operating the portal in support of
      the licenses purchased under the Sale Agreement.

      f. Return of Materials. Within thirty (30) days after the termination or
      expiration of this Agreement, CST shall return to all DynTek confidential
      information and other DynTek materials in its possession for shipment, as
      DynTek may direct, at DynTek's expense.

10.   Waiver of Certain Rights; Parties. This Agreement extends certain rights
not only to CST but also to affiliates of CST. Notwithstanding the above, DynTek
and its successors and assigns agree to look solely to CST and its assets for
the performance of CST's obligations hereunder and under the Sale Agreement,
including, but not limited to, the payment of the Purchase Price under the Sale
Agreement. Under no circumstances shall DynTek or its successors or assigns hold
or attempt to hold any officer, director, incorporator, shareholder (including,
but not necessarily limited to, Young Williams, P.C.) or employee liable or
responsible for the performance of CST's obligations hereunder or under the Sale
Agreement, under any legal or equitable theory of any nature, their recourse
being limited solely to CST and its assets.

11.   General Provisions

   a) Governing Law and Jurisdiction. Subject to the parties' agreement to
      arbitrate, any action or proceeding seeking to enforce any provision of,
      or based on any right arising out of, this Agreement shall be brought
      against any of the parties only within the courts of the State of
      Mississippi, County of Hinds, and each of the parties consents to the
      jurisdiction of such courts (and of the appropriate appellate courts) in
      any such action or proceeding and waives any objection to venue laid
      therein.

   b) Binding Arbitration.

      i)    Any controversy or claim arising out of or relating to this
            Agreement for the breach hereof which cannot be settled by the
            parties shall be settled by arbitration in accordance with the
            commercial arbitration rules of the American Arbitration Association
            ("AAA") as set forth herein.

      ii)   Each party may select one arbitrator. Selection shall be completed
            within ten (10) days of the receipt of a demand for arbitration. If
            either party fails to select an arbitrator within such ten- (10) day
            period, the one selected shall act as sole

<PAGE>
                                      -5-

            arbitrator. If two arbitrators have been selected, the two
            arbitrators selected shall select a third within fifteen (15) days
            after their selection. If they fail to do so, the AAA shall select
            the third arbitrator. The arbitrators shall set a date of hearing no
            later than sixty (60) days from the date all arbitrators have been
            selected. If the amount in controversy is less than $10,000.00, the
            parties shall mutually agree on one arbitrator to conduct the
            binding arbitration as mutually agreed by the parties outside of the
            AAA process. If the parties are unable to mutually agree upon one
            arbitrator or the alternative arbitration process within (10) days
            of the receipt of a demand for arbitration, the arbitration shall be
            conducted by the AAA as described above.

      iii)  The arbitration shall take place in Dallas, Texas.

      iv)   The award of any arbitration shall be final, conclusive and binding
            on the parties hereto.

      v)    The arbitrators may award any legal or equitable remedy. Judgment
            upon any arbitration award may be entered and enforced in any court
            of competent jurisdiction.

      vi)   Either party to arbitration hereunder may bring an action for
            injunctive relief against the other party if such action is
            necessary to preserve jurisdiction of the arbitrators or to maintain
            status quo pending the arbitrators' decision. Any such action called
            pursuant to this paragraph shall be discontinued upon assumption of
            jurisdiction by the arbitrators and their opportunity to consider
            the request for equitable relief pending final decision in the
            arbitration. c) Survival of Certain Terms. The provisions herein
            relating to the obligations to protect the other's trade secrets,
            copyrights, trademarks and proprietary and property rights and
            relating to enforcement of this Agreement, indemnity and warranties
            shall survive the termination or expiration of this Agreement for
            any reason. All other right and obligations of the parties shall
            cease upon termination or expiration of this Agreement.

   d) Entire Agreement. This Agreement, (including the Exhibits and Attachments
      which are attached hereto and referenced on the cover page, if any),
      constitutes the entire agreement of the parties with respect to the
      ProductivIT maintenance and support to be provided to CST and supercedes
      all prior agreements and understandings between them with respect to such
      matters. The Sale Agreement has been entered into regarding the license of
      ProductivIT. No modification of this Agreement, nor any waiver of any
      rights under this Agreement, shall be effective unless in writing and
      signed by both parties.

   e) Independent Review. Each party declares that, prior to the execution of
      this Agreement, they apprised themselves of sufficient relevant data,
      through their legal counsel or through other sources of their own
      selection, in order that they might intelligently exercise their own
      judgment in deciding whether to execute, and deciding on, the contents of
      this Agreement. They further declare that, except as set forth herein,
      their decision was not based on or influenced by any declarations or
      representations of the other party hereto, or of the agents or employees
      of such other party.

   g) Force Majeure. Nonperformance of either party shall be excused to the
      extent that performance is rendered impossible by strike, fire, flood,
      governmental acts or orders or restrictions, failure of suppliers, or any
      other reason where failure to

<PAGE>
                                      -7-

      perform is beyond the control and not caused by the negligence of the
      non-performing party.

   h) Non-assignability and Binding Effect. A mutually agreed consideration for
      DynTek entering into this Agreement is the reputation, business standing,
      and goodwill already honored and enjoyed by CST and its affiliates under
      its present ownership, and accordingly, CST agrees that it's rights and
      obligations under this Agreement may not be transferred or assigned
      directly or indirectly to anyone, by operation of law or otherwise, to
      anyone other than its current affiliates, without the prior written
      consent of DynTek. Subject to the foregoing sentence, this Agreement shall
      be binding upon and inure to the benefit of the parties hereto, their
      successors and assigns.

   i) Partial Invalidity. If any provision of this Agreement (other than Section
      9) is held to be invalid by a court of competent jurisdiction, then the
      remaining provisions shall nevertheless remain in full force and effect.
      The parties agree to negotiate in good faith any term held invalid (other
      than Section 9) and to be bound by the mutually agreed substitute
      provision. If Section 9 is held to be invalid by a court of competent
      jurisdiction, this entire Agreement shall be null and void; provided,
      however, DynTek and its successors and assigns still shall be deemed to
      have waived any and all rights to recover any damages from any person or
      entity other than CST, whether under quantum meruit, any other equitable
      theory or otherwise.

   j) Legal Expenses. The prevailing party in any legal action arising out of
      this Agreement shall be entitled, in addition to any other rights and
      remedies it may have, to reimbursement for its expenses, including court
      costs and reasonable attorney's fees.

   k) Counterparts. This Agreement may be executed in counterparts, each of
      which shall be deemed an original and which together shall constitute one
      instrument.

   l) Waiver. The failure of either party to exercise any right created hereby
      shall not be deemed a waiver of that right.

   m) Headings. The headings contained herein are not definitions, but rather
      are intended as topical finding aids and shall have no legal effect
      whatsoever.

IN WITNESS WHEREOF, the parties hereto have, through duly authorized officials,
executed this as of the Effective Date.
