9.5  [**] PRODUCTS. The parties to this Agreement wish to record their intention
to work together and cooperate in good faith [**] with the GOA product line.

9.6  TECHNICAL SUPPORT. Technical Support for the Products purchased by GOA
under this Agreement will be managed via a three-tier Technical Support
infrastructure and process as follows:

     LEVEL I TECHNICAL SUPPORT

     GOA will provide Level I Technical Support to their direct and indirect
     customers for all operating systems and environments supported by SWD's
     products. Level I Support is defined as calls* originating from GOA's
     customers, resellers or distributors regarding the Products, GOA Service,
     Wireless Service Providers, and GOA Products including, but not limited to,
     pre and post-sale inquiries concerning the basic operation of the hardware
     and software, functionality, interoperability and capabilities of those
     products and services. For calls regarding the Products, GOA will make
     every attempt to answer customer questions and resolve issues using
     available tools, documentation, test equipment and other materials used to
     support the Products. If the customer question I issue regarding the
     products cannot be resolved by GOA Level I support personnel to the
     customers' satisfaction, the issue will be forwarded to GOA Level II
     Technical Support for further investigation and resolution.

     *Calls include phone calls, e-mail, web-based inquiries, faxes and letters.

     LEVEL II TECHNICAL SUPPORT

     Level II Technical Support will be provided by GOA support staff directly
     to GOA Level I Support personnel to assist in the resolution of open
     customer issues that have not been resolved to the satisfaction of GOA
     customers during a Level I Support call. GOA Level II issues that are
     unresolved may be escalated to SWD Technical Support through designated GOA
     Level II support personnel. SWD will be available to handle GOA escalation
     requests during normal hours of operation (Weekdays 6:00 AM to 5.00 PM
     PST). SWD Technical Support will work directly with GOA Level II support
     staff to resolve issues and answer questions; this may require GOA support
     staff to gather additional information and provide system information or
     test results back to SWD support staff to aid in the definition and
     resolution of the problem. It will be GOA support staff's responsibility to
     communicate directly with the end-user customer.

     LEVEL III TECHNICAL SUPPORT (ESCALATION)

     Level III Technical Support will be provided by SWD support and system
     engineering staff to resolve issues that cannot be satisfactorily resolved
     by Level I and Level II Support personnel.

      operation and compatibility of the Products. It will be the duty of the

      will join TSANET to assist in resolving multivendor issues.

otherwise disposing of or dealing with any products or services whatsoever, now
or in the future.

11.1  DISCLAIMER. EXCEPT FOR THE EXPRESS WARRANTY SET FORTH IN SECTION 10.1,

EXPRESSED OR IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE WITH RESPECT
TO ANY PRODUCT.

11.2  LIMITATION OF LIABILITY. EXCEPT FOR CLAIMS RELATING TO SECTION 13.2,
NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY CONSEQUENTIAL (INCLUDING,
WITHOUT LIMITATION, LOST PROFITS AND BUSINESS INTERRUPTION), INCIDENTAL,
INDIRECT, SPECIAL, ECONOMIC, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO
THE TRANSACTIONS CONTEMPLATED UNDER THIS AGREEMENT, WHETHER FOR BREACH OR
REPUDIATION OF CONTRACT, BREACH OF WARRANTY, NEGLIGENCE OR OTHERWISE, EVEN IF
THE OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, EXCEPT FOR
AN INTELLECTUAL PROPERTY INDEMNITY OBLIGATION WHICH IS COVERED BY SECTION 12.1,
OR A BREACH OF WARRANTY CLAIM WHICH IS COVERED BY SECTION 10.1, THE LIABILITY OF
SWD AND ITS AFFILIATES UNDER OR FOR BREACH OF THIS AGREEMENT AND/OR THE SALE OF
PRODUCT IS LIMITED TO THE PURCHASE PRICE OF SUCH PRODUCT.


12.   INTELLECTUAL PROPERTY INDEMNITY

12.1  INDEMNITY. Except as specifically provided in section 12.2 below, SWD
shall, at all times during the currency of this Agreement and thereafter,
defend, indemnify and hold harmless GOA, its shareholders, officers, employees,
agents, affiliates and customers, from and against any damages, liabilities,
costs and expenses (including reasonable attorneys' fees) arising out of any
claim, suit or proceeding brought by a third party asserting that the Products,
or any part thereof, infringes or misappropriates any third party US patent,
trade secret, copyright, trademark or other proprietary right (collectively,
"Intellectual Property Rights"). In the event that such a claim is made, or in
SWD's opinion is likely to be made, or the use of the Products is enjoined or,

                                      -13-
   14
in SWD's opinion is likely to become the subject of an injunction preventing its
re-sale or use as contemplated herein, SWD will, at SWD's expense and sole
election either: (a) procure for GOA and its customers the right to use such
Products; (b) modify such Product so that it becomes non-infringing while giving
equivalent functionality and performance such that its use is not enjoined; or
(c) if neither of the foregoing options is reasonably available, refund to GOA
all amounts paid for the infringing Products, depreciated on a straight-line
basis over a three (3) year period. THE FOREGOING STATES THE SOLE AND EXCLUSIVE
LIABILITY OF SWD AND ITS AFFILIATES FOR INFRINGEMENT AND IS IN LIEU OF ANY AND
ALL WARRANTIES, EXPRESS OR IMPLIED OR STATUTORY, IN REGARD THERETO.

12.2  EXCLUSIONS. SWD shall have no liability or obligation to GOA or its
customers with respect to any patent, trade secret, copyright, trademark or
other proprietary right infringement claim to the extent based upon: (a) use of
the Products in an application or environment or on a platform or with devices
for which the Product was not designed or contemplated to the extent that such
use caused the infringement; (b) modifications, alterations, combinations or
enhancements of the Product not created by SWD or with SWD's consent, solely to
the extent that such modification, alteration, combination or enhancement caused
the infringement; (c) any patent, copyright or trade secret which GOA or any of
its Affiliates owns or has elusive interest; (d) any GOA defined feature that
SWD incorporates into a Product at GOA's request or (e) failure of GOA or its
customer to install any corrections or enhancements made available by SWD at no
charge that maintain equivalent or better functionality and performance, solely
to the extent that such correction or enhancement would have avoided the
infringement claim, SWD's obligations hereunder do not apply to any alleged
infringement occurring after GOA has received written notice of such alleged
infringement.


13.   LICENSE GRANT

13.1  LICENSE GRANT.

      (a)   The Products and their software and related documentation may bear
            certain tradenames, trademarks, trade devices, logos, codes or other
            symbols of SWD (the "INDICIA"). GOA will be allowed to use, and is
            encouraged to use, the Indicia in GOA's publicity related to the
            Products, provided that: (i) all uses of Indicia by GOA shall be
            subject to pro-publication or pre-use review and approval by SWD,
            and (ii) if, in SWD's judgment and prior to any use thereof by GOA,
            any use of Indicia by GOA is deemed detrimental to the Indicia or
            SWD's reputation, or is deemed otherwise undesirable, SWD may
            withdraw such permission without liability as a result thereof. Such
            use will inure to the benefit of SWD and will not vest in GOA any
            rights in or to the Indicia.

      (b)   GOA will not conduct business under any of the Indicia or
            derivatives or variations thereof, and GOA will not directly or
            indirectly hold itself out as having any relations to SWD or its
            Affiliates other than as set forth herein. Indicia may be used by
            GOA only to advertise and promote the Products themselves, and may
            not be used to identify GOA. Indicia will not be used in GOA's
            advertising, promotion, or catalogues in a manner that implies SWD's
            endorsement of products, software (including related documentation),
            or services

                                      -14-
   15
            not purchased from SWD. GOA will not remove or alter any Indicia
            applied to the Products or software (including related
            documentation) without the prior written approval of SWD.

contain or be accompanied by Software in executable code form (the "Software")
and, except as otherwise expressly provided herein, all references to "Products"
in this Agreement shall be deemed to include the accompanying Software, provided
that nothing herein shall be construed as the sale of any Software to GOA.
Pursuant to a separate license agreement provided by SWD to GOA and attached as
an Appendix hereto, SWD will grant to GOA a non-exclusive license to use, in
object form only, and sublicense to its end-user customers, the Software solely
in the Products for the duration of the useful life of such Products and subject
to the terms and conditions of this Agreement. GOA shall not, without the prior
written consent of SWD: (a) alter, modify, translate or adapt any Software or

sublicense or otherwise transfer the Software in whole or in pan, except as
permitted herein; (d) use the Software except as specifically contemplated in
this Agreement; or (e) disclose the Software to any third party. The entire

remove any copyright notices or other legends from the Software or any
accompanying documentation.


14.   OWNERSHIP OF INTELLECTUAL PROPERTY

14.1  OWNERSHIP BY SWD. Except for licenses otherwise expressly granted under
this Agreement, the sale of Products hereunder does not convey to GOA any
Intellectual Property Rights in the Products and GOA acknowledges SWD's
exclusive rights thereto. Neither the sale of Products or any provision of this
Agreement will be construed to grant to GOA, either expressly, by implication or
by way of estoppel, any license under any other Intellectual Property Rights of
SVM covering or relating to any other product or invention of SWD, or any
combination of the Product with any other product of SWD.


15.   FORCE MAJEURE

15.1  FORCE MAJEURE. Neither party shall be liable in any respect for its

intervention of any government authority, strikes, walkouts or other labor
disturbances, an industry-wide lack of components or materials or a shortage or
lack of components or materials from a single source supplier to SWD that has
claimed an event of force majeure, or delay in transportation beyond the
reasonable control of the party experiencing same (each a "Force Majeure"),
except that lack of funds or credit shall not constitute a Force Majeure. The
party so affected shall, upon giving prompt written notice to the other party of
the delay and the cause- therefor, be excused from performance to the extent of
the Force Majeure; provided however, that the party so affected shall use
reasonable efforts to avoid or remove such causes of non-performance and shall
continue performance hereunder with the utmost dispatch whenever such causes are
removed.
