                AT&T UNMODIFIED BINARY PRODUCT or AT&T DERIVED BINARY PRODUCT or
                put them into human readable form.

4.3.    LICENSEE shall require each LICENSEE DISTRIBUTOR to enter into a written
        agreement with its supplier of AT&T UNMODIFIED BINARY PRODUCTS or AT&T
        DERIVED BINARY PRODUCTS (LICENSEE or another LICENSEE DISTRIBUTOR)
        before any AT&T UNMODIFIED BINARY PRODUCT or AT&T DERIVED BINARY PRODUCT
        is furnished to such LICENSEE DISTRIBUTOR. Such agreement shall include
        provisions which are substantially equivalent to the relevant substance
        of Sections 4.2., 4.8., 4.10., and 4.11. of this Agreement. For a
        LICENSEE DISTRIBUTOR who is also to be an AUTHORIZED COPIER, such
        agreement shall also include provisions consistent with and containing
        the relevant substance of Sections 4.5., 4.7. and 4.9. of this
        Agreement; provided, however, that only LICENSEE, and AUTHORIZED COPIERS
        which have been so authorized by LICENSEE directly, may designate other
        LICENSEE DISTRIBUTORS as AUTHORIZED COPIERS.

4.4.    LICENSEE DISTRIBUTORS who are not also AUTHORIZED COPIERS may not make
        copies of AT&T UNMODIFIED BINARY PRODUCTS or AT&T DERIVED BINARY
        PRODUCTS, but may furnish to end user customers and other LICENSEE
        DISTRIBUTORS copies of AT&T UNMODIFIED BINARY PRODUCTS or AT&T DERIVED
        BINARY PRODUCTS furnished to such LICENSEE DISTRIBUTOR by LICENSEE or
        other LICENSEE DISTRIBUTORS. In such cases the product name appearing on
        such copies shall not be deleted or altered by such an LICENSEE
        DISTRIBUTOR.

4.5.    Consistent with Sections 4.9. and 4.10., a LICENSEE DISTRIBUTOR who is
        also an AUTHORIZED COPIER may make copies of AT&T UNMODIFIED BINARY
        PRODUCTS or AT&T DERIVED BINARY PRODUCTS and furnish such copies to end
        user customers and other LICENSEE DISTRIBUTORS with the other products,
        it any, and in the packaging of that LICENSEE DISTRIBUTOR'S choosing.

4.6.    LICENSEE shall use its reasonable efforts to enforce the agreements with
        LICENSEE DISTRIBUTORS and the end user customers of LICENSEE and
        LICENSEE DISTRIBUTORS.

4.7.    If an LICENSEE DISTRIBUTOR fails to fulfill one or more of its
        obligations required under this Agreement, AT&T may, upon its election
        and in addition to any other remedies that it may have, at any time
        notify LICENSEE in writing of such failure and request that LICENSEE
        terminate that LICENSEE DISTRIBUTOR'S rights granted through this
        Agreement by not less than three months' written notice to such LICENSEE
        DISTRIBUTOR specifying any such failure, unless within the period of
        such notice all failures specified therein shall have been remedied.
        Upon such termination LICENSEE shall determine a suitable time, not to
        exceed 120 days, for such LICENSEE DISTRIBUTOR to discontinue use of and
        return, or destroy and certify the destruction of, all copies of AT&T
        UNMODIFIED BINARY PRODUCTS or AT&T DERIVED BINARY PRODUCTS then in its
        possession for which Binary Distribution Fees (as defined in the
        applicable Supplement) have not been paid.

4.8.    LICENSEE agrees that when a SUBSIDIARY'S or an LICENSEE DISTRIBUTOR'S
        relationship to LICENSEE changes so that it is no longer a SUBSIDIARY of
        LICENSEE or an LICENSEE DISTRIBUTOR, (i) all rights of such former
        SUBSIDIARY or LICENSEE DISTRIBUTOR under this Agreement shall
        immediately cease, (ii) ail rights of all LICENSEE DISTRIBUTORS and all
        LICENSEE AUTHORIZED COPIERS whose rights derive from that former
        SUBSIDIARY or LICENSEE DISTRIBUTOR shall immediately cease, and (iii)
        such former SUBSIDIARY or LICENSEE DISTRIBUTOR shall return to LICENSEE,
        or destroy and certify the destruction of, all copies of AT&T UNMODIFIED
        BINARY PRODUCTS or AT&T DERIVED BINARY PRODUCTS then in its possession
        for which Binary Distribution Fees have not been paid. However, such
        former SUBSIDIARY or LICENSEE DISTRIBUTOR may continue to use, or
        LICENSEE may collect from such former SUBSIDIARY or LICENSEE DISTRIBUTOR
        and distribute, copies of AT&T UNMODIFIED BINARY PRODUCTS or AT&T
        DERIVED BINARY PRODUCTS for which Binary Distribution Fees have been
        paid on the same basis that an end user customer may use copies of AT&T
        UNMODIFIED BINARY PRODUCTS or AT&T DERIVED BINARY PRODUCTS pursuant to
        Section 4.2.

4.9.    Notices

        4.9.1.   Any notice provided by AT&T to LICENSEE in a timely manner,
                 acknowledging a contribution of a third party appearing in an
                 AT&T SOFTWARE PRODUCT, shall be included in corresponding
                 portions of AT&T UNMODIFIED BINARY PRODUCTS or AT&T DERIVED .
                 BINARY PRODUCTS made by LICENSEE or LICENSEE AUTHORIZED
                 COPIERS. Instructions regarding such notices may appear in the
                 Exhibits for certain AT&T SOFTWARE PRODUCTS.

        4.9.2.   Each portion of an AT&T UNMODIFIED BINARY PRODUCT or AT&T
                 DERIVED BINARY PRODUCT shall include an appropriate copyright
                 notice. Such copyright notice shall be the copyright notice or
                 notices appearing in or on the corresponding portions of the
                 AT&T SOFTWARE PRODUCT on which such AT&T UNMODIFIED BINARY
                 PRODUCT or AT&T DERIVED BINARY PRODUCT is based (except that
                 LICENSEE may remove all copyright notices of parties other than
                 AT&T from AT&T DERIVED BINARY PRODUCTS); in addition, if
                 copyrightable changes are made in developing such AT&T DERIVED
                 BINARY PRODUCT, LICENSEE, may include a copyright notice
                 identifying the owner of such changes. Nothing in this
                 Agreement will constitute an approval by AT&T for LICENSEE to
                 use AT&T's logos.

        packaging without AT&T's prior written permission. LICENSEE shall not
        use or imitate the trade dress of AT&T's products without the prior

5.      LICENSEE DESIGNATED SITES

        DESIGNATED SITES for specific AT&T SOURCE SOFTWARE. AT&T reserves the
        right to approve or disapprove of LICENSEE's proposed changes; however,
        AT&T may not withhold its approval of changes involving LICENSEE owned
        or operated facilities, and will not otherwise unreasonably withhold its
        approval. AT&T will prepare an amendment to the Supplement for that AT&T
        SOURCE SOFTWARE to cover such approved changes. Changes covered by such
        an amendment shall become effective after execution of such amendment by
        LICENSEE and by AT&T and, in the case of each additional DESIGNATED
        SITE, receipt by AT&T of the appropriate fee; replacement DESIGNATED
        SITES do not require the payment of additional fees.

5.2.    On AT&T's request, but not more frequently than annually, LICENSEE shall
        furnish to AT&T a statement, certified by an authorized representative
        of LICENSEE, listing the location of all DESIGNATED SITES hereunder and

        full compliance with the provisions of this Agreement.

6.      LICENSEE CONTRACTORS

        and allow use of AT&T SOURCE SOFTWARE by its contractors at the

        written agreements between LICENSEE and such contractors in accordance
        with Section 6.5.

6.2.    Any claim, demand, or right of action arising on behalf of a contractor
        from the furnishing to it or use by it of AT&T SOFTWARE PRODUCTS shall
        be solely against LICENSEE.

6.3.    When a contractor's work for LICENSEE is completed, all copies of AT&T
        SOURCE SOFTWARE furnished to such contractor or made by such contractor
        and all copies of any DERIVATIVE WORKS made by such contractor based on
        AT&T SOURCE SOFTWARE shall be returned to LICENSEE or destroyed,
        including any copies stored in any computer memory or storage medium.

6.4.    A contractor may not acquire any ownership interest in any DERIVATIVE
        WORK of AT&T SOURCE SOFTWARE.

6.5.    LICENSEE and each of its contractors shall enter into a written
        agreement before or at the time LICENSEE permits access to or allows use
        of AT&T SOURCE SOFTWARE by that contractor, or LICENSEE furnishes AT&T
        SOURCE SOFTWARE to that contractor, in which that contractor shall agree
        to the same responsibilities and obligations as to confidentiality and
        other restrictions pertaining to the use of AT&T SOURCE SOFTWARE as
        those undertaken by LICENSEE under this Agreement. Such written
        agreement shall also be consistent with the requirements of this
        Section. Copies of such agreements shall be provided to AT&T on request;
        however, portions of such agreements not required by this Section may be
        deleted from such copies.

        Subject to the provisions found in the Exhibit of the Supplement for the
        particular AT&T SOFTWARE PRODUCT, AT&T shall furnish to LICENSEE one
        copy of such AT&T SOFTWARE PRODUCT in the form identified in the Exhibit
        of the Supplement, and in accordance with the schedule in the Exhibit of
        the Supplement, for such products.

8.      ACCEPTANCE BY LICENSEE

8.1.    LICENSEE shall have 60 days from receipt of a version of an AT&T
        SOFTWARE PRODUCT, supported and tested by AT&T, to ensure that said
        product conforms with the specifications set forth in the Exhibit of the
        Supplement attached hereto.

8.2.    If an AT&T SOFTWARE PRODUCT does not conform with the specifications
        specified in Section 8.1., LICENSEE may promptly notify AT&T in writing
        of such non-conformance in reasonable detail. AT&T shall have 45 days
        after receipt of such notice, or such longer time as the parties may
        agree, to correct such non-conformance. AT&T shall use reasonable
        efforts to correct any reproducible non-conformance and to resubmit a
        corrected AT&T SOFTWARE PRODUCT within the initial 45 days following
        receipt of the initial notice from LICENSEE. LICENSEE shall have 30 days
        after re-submission of such corrected AT&T SOFTWARE PRODUCT to again
        evaluate it against the applicable specifications. In the event that
        such resubmitted product still exhibits nonconformance, LICENSEE may
        again notify AT&T in writing of such remaining non-conformance within 30
        days after the receipt of the corrected AT&T SOFTWARE PRODUCT. In the
        event that (i) within 30 days after receipt of the second notice
        specified above AT&T has not corrected any remaining non-conformance
        that is reproducible and resubmitted a corrected version of such AT&T
        SOFTWARE PRODUCT to LICENSEE, or (ii) such resubmitted product still
        exhibits reproducible non-conformance, LICENSEE may immediately
        terminate the applicable Supplement upon written notice to AT&T, AT&T
        shall refund all fees paid by LICENSEE for such AT&T SOFTWARE PRODUCT,
        and LICENSEE shall certify the destruction of all copies of such AT&T
        SOFTWARE PRODUCT in accordance with Section 13.2. of this Agreement.

9.      EXPORT BY LICENSEE

9.1.    LICENSEE agrees that it will comply with any and all applicable laws
        governing export of AT&T SOFTWARE PRODUCTS. LICENSEE agrees that it will
        obtain any and all necessary export licenses for any export. For
        purposes of this Section 9., "export by LICENSEE" includes any
        disclosure of an AT&T SOFTWARE PRODUCT to a foreign national where such
        disclosure is considered an export by the applicable export control
        authority. LICENSEE's obligations to AT&T in this Section 9.1. are
        subject to AT&T providing LICENSEE with the usual published technical
        specifications and Export Commodity Control Numbers, as appropriate, to
        enable LICENSEE to make its own licensing determinations or applications
        for such products.

        such Supplement, LICENSEE shall pay to AT&T the fee required by such
        additional Supplement for the DESIGNATED SITES or the AT&T SOFTWARE
        PRODUCT listed in such additional Supplement.

10.3.   LICENSEE shall be responsible for the payment of all taxes, including
        any sales or use tax (and any related interest or penalty), however
        designated, imposed as a result of the licensing of AT&T SOFTWARE
        PRODUCTS and development activities hereunder, except (i) any taxes

        activities contemplated by this Agreement; and (ii) taxes based on
        AT&T's net income or franchise taxes imposed by any governmental entity.
        Subject to the foregoing, fees specified in Supplements to this
        Agreement and in Exhibits attached to such Supplements do not include
        taxes. If AT&T is required to collect a tax to be paid by LICENSEE,
        LICENSEE shall reimburse AT&T for that tax paid by AT&T within 60 days
        of demand unless LICENSEE disputes the obligation to pay such tax.

        and locations of LICENSEE AUTHORIZED COPIERS.

12.4.   AT&T shall have the right, for three years after the events they
        reflect, through its accredited third party auditing representatives, to
        make an examination and audit, during normal business hours, not more
        frequently than annually, upon reasonable prior notice to LICENSEE, of

       pursuant to this Section and Section 11. by LICENSEE for itself and
       LICENSEE AUTHORIZED COPIERS and such other records and accounts as may
       under recognized accounting practices contain information bearing upon
       the amounts payable to AT&T under this Agreement. Upon reasonable cause,
       AT&T may request that LICENSEE conduct an audit of an LICENSEE AUTHORIZED
       COPIER and permit AT&T's accredited third party auditing representative
       to review the results. Prompt adjustment shall be made by the proper
       party to compensate for any errors or omissions disclosed by such
       examination or audit. Neither such right to examine and audit, nor the
       right to receive such adjustment, shall be affected by any statement to
       the contrary appearing on checks or otherwise, unless such statement
       appears in a letter signed by the party having such right and delivered
       to the other party expressly waiving such right. The failure of AT&T to
       request an audit prior to the expiration of LICENSEE's obligation to
       retain records shall not constitute a waiver of any cause of action which
       arises out of this Agreement. AT&T agrees that, prior to conducting such
       an audit, its auditing representative will sign a suitable
       confidentiality agreement with LICENSEE and it will disclose to AT&T only
       that information which is necessary for AT&T to understand the findings
       of the audit, which information will in no event include the names and
       locations of LICENSEE customers. AT&T shall pay the fees and expenses of
       the auditor unless the auditor's report shows noncompliance in an
       aggregate amount exceeding 10% of the amount properly due, in which case
       LICENSEE shall pay the fees and expenses of the auditor for that audit.
       An audit conducted under this Section 12.4. shall not in any way affect
       LICENSEE's obligation to comply with its financial obligations under this
       Agreement.

13.    TERM AND TERMINATION

13.1.  The term of this Agreement begins on the EFFECTIVE DATE and continues
       until terminated pursuant to this Section 13.

13.2.  LICENSEE may terminate its rights under this Agreement with respect to a
       AT&T SOFTWARE PRODUCT by certifying in writing that LICENSEE has
       discontinued use of and returned or destroyed all copies of AT&T
       SOFTWARE PRODUCT.

13.3.  If one party materially breaches one or more of its obligations under
       this Agreement, the other party may at any time, upon its election and
       in addition to any other remedies that it may have, initiate termination
       of all the rights granted by it hereunder, by not less than two months'
       written notice to the breaching party specifying such breach in
       reasonable detail. If the breaching party is unable to cure such breach
       within such two month period, or after a reasonable additional period if
       the breach is of a type which by its nature cannot reasonably be cured
       within two months, the nonbreaching party may, by further written
       notice, terminate this Agreement 30 days from the date of such further
       notice, unless within such additional 30 day period such breach has been
       cured. Notwithstanding the foregoing, if the breaching party is in
       material default of its confidentiality or use obligations under Section
       16., the non-breaching party may, upon its election and in addition to
       any other remedies that it may have, immediately terminate all rights
       granted by it hereunder. If the breaching party is LICENSEE, upon any
       such termination, LICENSEE shall immediately discontinue use of and
       return, or destroy and certify the destruction of, all copies of the
       AT&T SOFTWARE PRODUCTS, except as Section 13.4. provides.

13.4.  If termination occurs under Section 13.3. after LICENSEE has furnished
       copies of AT&T UNMODIFIED BINARY PRODUCT or AT&T DERIVED BINARY PRODUCT
       to an end user, under a license granted hereunder, the LICENSEE may
       retain sufficient copies of the AT&T SOURCE SOFTWARE for the sole
       purpose of fulfilling contractual obligations to provide ongoing support
       to that end user. At such time as the LICENSEE has no contractual
       obligations to any end users for ongoing support, the LICENSEE shall
       immediately stop using, and shall return or certify the destruction of,
       all copies of the AT&T SOURCE SOFTWARE, AT&T UNMODIFIED BINARY PRODUCTS,
       AND AT&T DERIVED BINARY PRODUCTS.

13.5.   In the event of termination of rights under Sections 13.2. or 13.3.,
        each party shall refund any amounts paid to it under this Agreement
        which amounts were overpaid by the other, but no other amounts properly
        paid under this Agreement shall be refunded.

13.6.   A waiver of a breach of any term of this Agreement shall not be
        construed as a waiver of any later breach of that term or as a waiver of
        the term itself. A party's performance after the other party's breach
        shall not be construed as a waiver of that breach.

13.7.   The following shall survive termination of this Agreement for any
        reason: Sections 4.8., 6.4., 9., 10.3., 12., 13., 14., 16., 17.1.,
        17.3., 17.10., 17.11., and any other Sections or Exhibits to the extent
        necessary to achieve the survival of any Sections specified in this
        Section 13.7.; no other Sections of this Agreement shall survive
        termination. In addition, all financial obligations which had 'accrued
        but which were unpaid as of the effective date of termination shall
        survive termination, and all financial obligations which would have
        accrued after the effective date of termination shall terminate.

14.     AT&T WARRANTY AND INDEMNIFICATION

14.1.   SUBJECT TO SECTION 14.1.1., AT&T AND OTHER DEVELOPERS MAKE NO OTHER
        REPRESENTATIONS OR WARRANTIES, EXPRESSLY OR IMPLIEDLY. BY WAY OF EXAMPLE
        BUT NOT OF LIMITATION, AT&T AND OTHER DEVELOPERS MAKE NO REPRESENTATIONS
        OR WARRANTIES OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE.

        14.1.1. AT&T represents that it has the sufficient right, title, and
                interest in the AT&T SOFTWARE PRODUCTS in the unmodified form
                provided to LICENSEE hereunder to enter into this Agreement.
                AT&T agrees to defend, at its expense, any suit against
                LICENSEE, based upon a claim that AT&T does not have sufficient
                right, title, and interest in the AT&T SOFTWARE PRODUCTS to make
                this Agreement, or that the AT&T SOFTWARE PRODUCT infringes, a
                United States trademark or copyright (insofar as such
                infringement relates to the DOCUMENTATION for or the code of the
                AT&T SOFTWARE PRODUCT), and to pay any settlement, or any
                damages finally awarded after appeal (including costs and
                attorney fees, if any, awarded as part of the final judgment) in
                any such suit.

        14.1.2. AT&Ts obligations under Section 14.1.1. shall not be effective
                unless (i) AT&T is notified in writing of any notice of claim or
                of threatened or actual suit and (ii) AT&T is given full control
                of the defense and/or settlement, together with full cooperation
                by LICENSEE at AT&T's expense, including the provision of all
                relevant information available to LICENSEE, with respect to such
                defense and/or settlement of the same.

        14.1.3. Following written notification of a claim of a threatened or
                actual suit, AT&T may at its own expense and in addition to
                AT&T's obligations in Section 14.1.1. (i) procure for LICENSEE
                the right to continue to market, use, and have others use the
                alleged infringing AT&T SOFTWARE PRODUCT; or (ii) make it
                non-infringing; or (iii) if a permanent injunction should issue
                terminate the applicable Supplement for such AT&T SOFTWARE
                PRODUCT and refund all the fees (subject to five year straight
                line depreciation) received from LICENSEE for such AT&T SOFTWARE
                PRODUCT. If AT&T elects to replace or modify such AT&T SOFTWARE
                PRODUCT, such replacement shall meet substantially the
                specifications as provided or referenced in the applicable
                Exhibit of the Supplement for such AT&T SOFTWARE PRODUCT.

        14.1.4. AT&T shall have no liability for any claim alleging patent
                infringement whatsoever, or for copyright infringement based on
                LICENSEE's, an LICENSEE DISTRIBUTOR'S, or an end user's (i)
                continued use after notification of infringement of other than
                the then

                current release of the AT&T SOFTWARE PRODUCT received from AT&T
                if such claim would have been avoided by use of the then current
                release so long as that release was made available to LICENSEE,
                LICENSEE DISTRIBUTORS, and end users without additional charge,
                (ii) combination of an AT&T SOFTWARE PRODUCT with a product not
                delivered by AT&T hereunder, or (iii) the development of a
                DERIVATIVE WORK, if such claim would have been avoided by the
                exclusive use of the AT&T SOFTWARE PRODUCT in the form delivered
                by AT&T to LICENSEE hereunder.

        14.1.5. AT&T shall have no obligation to LICENSEE for any claim made
                against LICENSEE which arises from the unauthorized use,
                license, or other disposition of an AT&T SOFTWARE PRODUCT
                outside the United States, and LICENSEE hereby releases and
                discharges AT&T from any and all claims resulting from such
                use.

14.2.   The obligations of this Section 14. shall survive termination of this
        Agreement.

15.     SUPPORT

        Except as may otherwise be expressly provided in this agreement or in
        another written agreement signed by both parties, AT&T is not obligated
        to provide support, assistance, information, or DOCUMENTATION for its
        SOFTWARE PRODUCTS to any person, including LICENSEE.

16.     CONFIDENTIALITY AND USE

16.1.   LICENSEE shall hold all parts of the AT&T SOURCE SOFTWARE subject to
        this Agreement in confidence for AT&T during the term of this Agreement,
        and if this Agreement is terminated for any reason, for a period
        extending five years beyond LICENSEE's return or certified destruction
        of AT&T SOURCE SOFTWARE. LICENSEE further agrees that it shall not make
        any disclosure of any or all of such all copies AT&T SOURCE SOFTWARE
        (including methods or concepts utilized therein) to anyone, except to
        employees and contractors of LICENSEE to whom such disclosure is
        necessary for the uses for which rights are granted hereunder. LICENSEE
        shall appropriately notify each employee and contractor to whom any such
        disclosure is made that such disclosure is made in confidence and shall
        be kept in confidence by such employees and contractor.

 16.2.  Notwithstanding anything to the contrary herein, neither party shall
        have the obligation to preserve the confidentiality of any information
        if such information:

        16.2.1. was previously known to the receiving party free of any
                obligation to keep it confidential as evidenced by
                documentation in such party's possession; or

        16.2.2. is or becomes publicly available by other than unauthorized
                disclosure by the receiving party; or

        16.2.3. is developed by or on behalf of the receiving party
                independent of this Agreement; or

        16.2.4. is received by the receiving party from a third party whose
                disclosure does not violate any confidentiality obligation with
                the disclosing party, or with that party; or

        16.2.5. is approved for release by written authorization by the
                disclosing party; or

        16.2.6. is lawfully required for use by a governmental agency or in a
                court proceeding, or must be disclosed by operation of law.

 16.3.  LICENSEE agrees that it will not use AT&T SOURCE SOFTWARE subject to
        this Agreement except as authorized herein and that it will not make,
        have made, or permit to be made any copies

      of such AT&T SOURCE SOFTWARE except for use at DESIGNATED SITES for such
      AT&T SOURCE SOFTWARE (including backup and archive copies necessary in
      connection with such use). Each such copy shall contain any copyright
      notice, proprietary notice, or notice giving credit to another developer,
      which appears on or in the AT&T SOURCE SOFTWARE being copied. Specific
      instructions regarding such notices may also appear in the Exhibits of
      the Supplement for certain AT&T SOURCE SOFTWARE.

17.   MISCELLANEOUS

      legends which may appear in an AT&T SOFTWARE PRODUCT.

17.2. Neither this Agreement nor any rights hereunder, in whole or in part,
      shall be assignable or otherwise transferable by either party, and any
      purported assignment or transfer shall be null and void. The foregoing
      shall not apply to assignments to SUBSIDIARIES of the parties to this
      Agreement, nor to assignments in connection with a party's transfer of
      all or a substantial portion of its assets, product lines, or
      businesses, or by reason of acquisition, merger, consolidation, or
      operation of law; however, the party assigning this Agreement under this
      sentence shall promptly communicate the assignment to the other party in
      a written notice.

      Unless otherwise provided in Supplements or Exhibits to this Agreement,
      no right is granted herein to either party to this Agreement to use any
      identifying mark (such as, but not limited to, trade names, trademarks,
      trade devices, service marks, or symbols, and abbreviations,
      contractions, or simulations thereof) owned by, or used to identify any
      product or service of, the other party. Except as is otherwise provided
      by law, the parties agree that they will not, without the prior written
      permission of the other party, (i) use any such identifying mark in
      advertising, publicity, packaging, labeling, or in any other manner to
      identify any of its products or services or (ii) represent, directly or
      indirectly, that any product or service of the other party is a product
      or service of such party or is made in accordance with or utilizes any
      information or DOCUMENTATION of the other party.

 17.4.Neither party shall be liable to the other for delays in performing
      under this Agreement if the delay is caused by shortage of labor,
      strike, lockout, default or failure of suppliers, riot, war, government
      action, law, or regulation, act of God, fire, flood, or other cause
      beyond the party's reasonable control.

        17.5. Each party to this Agreement may change an address relating to it
        by written notice to the other party.

17.9.   This Agreement shall not be construed to limit either parties right to
        obtain services or software programs from other sources, to prohibit or
        restrict either party from independently developing or acquiring
        competitive materials, or to restrict either party from making, having
        made, using, leasing, licensing, selling or otherwise disposing of any
        products or services whatsoever, nor is either party's right to deal

        hereby. The foregoing sentence shall not be construed as an implied
        license under any patent, copyright, or other intellectual property
        right of any party.

17.10.  This Agreement shall be governed by the rules and laws of the State of
        California. LICENSEE and AT&T agree to submit any dispute or controversy
        arising out of or relating to this Agreement to nonbinding mediation to
        be held in accordance with the Commercial Mediation Rules of the
        American Arbitration Association. This Section 17.10. will not apply to
        any issues of intellectual property. LICENSEE and AT&T agree that their
        participation in a mediation and the entire mediation proceeding,
        including but not limited to all statements, discussions, conduct,
        rulings, findings, or determinations in that mediation proceeding or
        relating to it, will be confidential, will constitute settlement
        negotiations under Rule 408 of the Federal Rules of Evidence, and will
        not be admissible in any proceeding or action of any kind, and that
        neither party will introduce or attempt to introduce the above in any
        other proceeding or action. The parties agree to perform whatever steps
        are necessary to ensure that each mediation proceeding complies with
        this Section 17.10.

17.11.  If any section or subsection of this Agreement or any Supplement or
        Exhibit is found by competent judicial authority to be invalid, illegal,
        or unenforceable in any respect, then that section or subsection in
        every other respect, and the remainder of this Agreement and its
        Supplements and Exhibits, shall continue in effect if the Agreement and
        its Supplements and Exhibits still express the intent of the parties as
        of the EFFECTIVE DATE. If that intent cannot be preserved, this
        Agreement and its Supplements and Exhibits shall be either re negotiated
        or terminated.

       2.1. When the KIT is sold as a separate product (Unbundled), LICENSEE
            must use a designation selected in accordance with the following:

            2.1.1.   The KIT designation contains "Advanced Server Version X for
                     (operating system] (where X designates the corresponding
                     release of AT&T's Advanced Server for UNIX Systems), or any
                     other designation mutually agreed to by both parties; and

            2.1.2.   When the initial screen pops up in the BINARY PRODUCT,
                     LICENSEE states prominently that its KIT "is", "is based
                     on" or "incorporates" AT&T's Advanced Server for UNIX
                     System. ("Compatible with", "derived from", or the like
                     wording does NOT satisfy this requirement); and

            2.1.3.   On the outside of the KIT packaging, LICENSEE states
                     prominently that its KIT "is", "is based on" or,

                     ("Compatible with", "derived from", or the like wording
                     does NOT satisfy this requirement); and

            2.1.4.   In all KIT documentation, collateral materials, press
                     releases and advertisements, on the same page and with
                     reference to the first use of LICENSEE'S KIT designation,
                     LICENSEE indicates in the text or by footnote that their
                     KIT "is", "is based on" or "incorporates", AT&T's Advanced
                     Server for UNIX Systems. ("Compatible with", "derived
                     from", or the like wording does NOT satisfy this
                     requirement).

       2.2. When the KIT is sold as part of another product, or will in no way
            be identified as a separate product from a larger integrated
            product (Bundled) LICENSEE must use a designation selected in
            accordance with the following:

            2.2.1.   When the initial screen pops up in the BINARY PRODUCT,
                     LICENSEE states prominently that its KIT "is", "is based
                     on" or "incorporates" AT&T's Advanced Server for UNIX
                     Systems. ("Compatible with", "derived from", or the like
                     wording does NOT satisfy this requirement); and

            2.2.2.   In all product documentation LICENSEE indicates in the text
                     or by footnote that their KIT "is", "is based on" or
                     "incorporates", AT&T's Advanced Server for UNIX Systems.
                     ("Compatible with", "derived from", or the like wording
                     does NOT satisfy this requirement).
