         3.2 RESTRICTION ON 3COM LICENSING OF GALAHAD PATENTS. 3Com agrees
that it will not license any of the Galahad Patents to any Third Party for
use in lightweight handheld mobile computing devices or operating systems for
such devices; provided, however, that 3Com retains the right to license the
Galahad Patents to Third Parties for such use for defensive purposes (i.e.,
to resolve a claim of patent infringement brought against 3Com by a Third
Party).

         3.3 RESTRICTION ON PALM'S "HAVE MADE" RIGHTS TO GALAHAD PATENTS. The
license granted in Section 3.1 to have Palm Products made by a Third Party
shall (i) only apply when the portion of the "have made" Palm Product covered
by the Galahad Patents has been designed or created by Palm and/or one of
Palm's subcontractors (not such Third Party) who is not a direct competitor
of 3Com in the field of the Palm Product being designed or created and (ii)
shall not apply to (A) any methods used, or (B) any Palm Products or portions
thereof that have been manufactured or marketed, by a Third Party prior to
Palm furnishing the designs or creations to such Third Party.

         3.4 COMBINATION EXCLUSION. Except as expressly provided herein, no
license or immunity is granted under this Agreement by 3Com, either directly
or by implication, estoppel or otherwise to any third parties acquiring Palm
Products from Palm for the combination of such Palm Products with other items
or for the use of such combination. Notwithstanding the previous sentence,

                                     -6-
<PAGE>

3Com grants to the direct and indirect customers of Palm, an immunity from
suit under the Galahad Patents for the combination of any such Palm Products
with other Palm Products and their use in such combination where the Palm
Products have no other substantial noninfringing use aside from the
combination with other Palm Products sold or otherwise transferred by Palm
directly or indirectly to such customer.

         3.5 PALM'S SUBLICENSE RIGHTS WITH RESPECT TO GALAHAD PATENTS.

                  (a) Palm may grant sublicenses to its Subsidiaries under
the license grant set forth in Section 3.1 within the scope of Palm's license
hereunder (with no right to grant further sublicenses other than, in the case
of a sublicensed Subsidiary, to another Subsidiary of Palm and as described
in Section 3.5(c) below).

                  (b) Any sublicense under Section 3.5(a) may be made
effective retroactively, but not prior to the sublicensee's becoming a
Subsidiary of Palm.

                  (c) Any Palm Product for which a software license is
granted by Palm (or any sublicensed Subsidiary) to its distributors,
resellers, OEM customers, VAR customers, VAD customers, systems integrators
and other channels of distribution and to its end user customers (including,
but not limited to, the Palm operating system) shall be considered to be
covered under the license grant set forth in Section 3.1 within the scope of
Palm's license hereunder, but only to the extent that the Palm Product
incorporates the technology covered by the claims of the Galahad Patents.

                  (d) Palm shall have no rights to grant sublicenses to the
Galahad Patents, except as expressly provided in Section 3.5 (a), (b) and (c)
above.

         3.6 DURATION.

                  (a) All licenses granted herein with respect to each Patent
shall expire upon the expiration of the term of such Patent.

                  (b) All sublicenses granted pursuant to this Agreement to a
particular Subsidiary of Palm shall terminate the date that the Subsidiary
ceases to be a Subsidiary of Palm.

         3.7 ACQUISITION OF PALM OR TRANSFER OF A BUSINESS OR SUBSIDIARY
RELATED TO GALAHAD PATENTS.

                  (a) If Palm, after the Separation Date, transfers all or
substantially all of its business or assets, or all or substantially all of
the business or assets to which the Galahad Patents relate, then regardless
of whether such transfer is part of (i) an asset sale to any Third Party, or
(ii) a sale of shares or securities in Palm or a Subsidiary to a Third Party
(in each case, any such Third Party shall be referred to herein as a
"Transferee"), then upon written request by Palm and the Transferee to 3Com
within sixty (60) days following the transfer, 3Com shall grant a
royalty-free

                                     -7-
<PAGE>

license to the Transferee with respect to the Galahad Patents under the same
terms of the license granted to Palm under this Agreement subject to the
following:

                                (i) the effective date of such license shall
be the effective date of transfer; and

                                (ii) the products and services of the
Transferee that are subject to such license shall be limited to the specific
Palm Products in the transferred business that are (A) commercially released
as of the date of transfer or which, prior to the transfer, (B) were planned
for release within three (3) months from the date of transfer and actually
are commercially released within three (3) months from the date of transfer
and (C) for new versions of such specific Palm Products covered by clauses
(A) and (B) above that have merely minor differences from such Palm Products
with no additional features; and

                                (iii) the Galahad Patents that are subject to
such license shall be limited to the Galahad Patents that are entitled to a
First Effective Filing Date before the date of such transfer; and

                                (iv) the Transferee shall have no right to
grant sublicenses (except as set forth in Section 3.5(c) above); and

                                (v) this Section 3.7 shall be excluded from
such license in any event and therefore 3Com shall have no obligation to
grant a license to a subsequent transferee;

                  (b) provided, that 3Com shall have no obligation to grant
such license unless the Transferee grants to 3Com a royalty-free license
under a comparable license grant as the license granted to Palm under this
Agreement, subject to the following:

                                (i) the effective date of such license shall
be the effective date of the transfer; and

                                (ii) the products and services of 3Com that
are subject to such license shall be all the 3Com Products; and

                                (iii) the Patents of the Transferee that are
subject to such license shall be the Patents owned or controlled by the
Transferee claiming inventions in the wireless field that are entitled to a
First Effective Filing Date on or before the date of such transfer and
applications for such patents (including without limitation any
continuations, continuations-in-part, divisions and substitutions); and

                  (c) provided, further, that in the event that 3Com and the
Transferee are engaged in litigation, arbitration or other formal dispute
resolution proceedings covering Patent infringement (pending in any court,
tribunal, or administrative agency or before any appointed or agreed upon
arbitrator in any jurisdiction worldwide), then 3Com shall have no obligation
to grant such license to the Transferee under this Section 3.7.

         3.8 COPIES OF PATENT APPLICATIONS AND INVENTION DISCLOSURES. 3Com
agrees, at its own expense from time to time upon Palm's request, to provide
to Palm copies of (i) the Assigned Patents and (ii) the Galahad Patents.

         3.9 THIRD PARTY PATENTS. 3Com confirms that it has granted, and
hereby grants (and agrees to cause its appropriate Subsidiaries to grant) to
Palm, under the Third Party Patents, a nonexclusive, worldwide sublicense to
make (including the right to practice methods, processes and procedures),
have made, use, lease, sell, offer for sale and import any products and
services subject to any and all terms and conditions set forth in the
applicable agreement between 3Com and the Third Party Patent owner, but only
to the extent and for the period of time 3Com has the legal right to grant
such a sublicense. 3Com shall respond to reasonable inquires from Palm
regarding any Third Party Patents.

         3.10 3COM COVENANT NOT TO SUE.

                  (a) 3Com irrevocably grants, on behalf of itself and its
Subsidiaries, at no charge, an immunity from suit to Palm and its
Subsidiaries, and its or their direct or indirect customers and Third Party
manufacturers (subject to the restrictions set forth in the next sentence)
for infringement of any 3Com Patent by any Current Palm Product. The
foregoing covenant with respect to Third Party manufacturers (i) shall apply
only when the portion of the "have made" Current Palm Product covered by the
3Com Patents has been designed or created by Palm and/or one of Palm's
subcontractors (not the Third Party manufacturer) who is not a direct
competitor of 3Com in the field of the Current Palm Product being designed or
created and (ii) shall not apply to (A) any methods used, or (B) any products
or portions thereof that have been manufactured or marketed, by any Third
Party prior to Palm furnishing the designs or creations to such Third Party.
No immunity is granted under the foregoing covenant by 3Com, either directly
or by implication, estoppel or otherwise to any Third Parties acquiring
Current Palm Products from Palm for the combination of such Current Palm
Products with other items or for the use of such combination; provided,
however, that the foregoing covenant shall apply to the direct and indirect
customers of Palm for the combination of any such acquired Current Palm
Products with other Palm Products and their use in such combination where the
acquired Current Palm Products have no other substantial noninfringing use
aside from the combination with other Palm Products sold or otherwise
transferred by Palm directly or indirectly to such customer.

                  (b) The foregoing covenant shall continue with respect to
each 3Com Patent for the term of such 3Com Patent.

                  (c) If Palm, after the Separation Date, transfers all or
substantially all of its business or assets, or transfers a Subsidiary or
business unit, then regardless of whether such transfer is part of (i) an
asset sale to any Third Party, or (ii) a sale of shares or securities in Palm
or a Subsidiary to a Third Party (in each case, any such Third Party shall be
referred to herein as a "Transferee"), then upon written request by Palm and
the Transferee to 3Com within sixty (60) days following the transfer, 3Com
shall grant an immunity from suit to the Transferee under the same terms as
the covenant set forth in Section 3.10 (a) and (b) above subject to the
following:

                                     -9-
<PAGE>

                                (i) the effective date of such covenant shall
be the effective date of transfer; and

                                (ii) the products and services of the
Transferee that are subject to such covenant shall be limited to the specific
Current Palm Products in the transferred business that are (A) commercially
released as of the date of transfer or which, prior to the transfer, (B) were
planned for release within three (3) months from the date of transfer and
actually are commercially released within three (3) months from the date of
transfer and (C) for new versions of such specific Current Palm Products
covered by Clauses (i) or (ii) above that have merely minor differences from
such Current Palm Products with no additional features; and

                                (iii) the 3Com Patents that are subject to
such covenant shall be limited to the 3Com Patents that are entitled to a
First Effective Filing Date before the date of such transfer and, in the
event that the transfer is a transfer of a Subsidiary or business unit and
not all or substantially all of Palm's business or assets, then the 3Com
Patents that are subject to such covenant shall be limited to the 3Com
Patents in the field of use of the transferred Subsidiary or business ; and

                                (iv) this Section 3.10(c) shall be excluded
from such covenant in any event and therefore 3Com shall have no obligation
to grant a covenant not to sue to any subsequent transferee;

                                (v) provided, however, that 3Com shall have
no obligation to grant such covenant unless the Transferee grants to 3Com and
its customers and suppliers a covenant not to sue at no charge on the
following terms:

                                             (1) the effective date of such
covenant shall be the effective date of the transfer; and

                                             (2) the products and services of
3Com that are subject to such covenant shall be the 3Com Products; and

                                             (3) the Patents of the
Transferee that are subject to such covenant shall be all the Patents owned
or controlled by the Transferee that are entitled to a First Effective Filing
Date before the date of such transfer and applications for such Patents
(including without limitation any continuations, continuations-in-part,
divisions and substitutions); and

                                (vi) provided, further, that in the event
that 3Com and any such Transferee are engaged in litigation, arbitration or
other formal dispute resolution proceedings covering Patent infringement
(pending in any court, tribunal, or administrative agency or before any
appointed or agreed upon arbitrator in any jurisdiction worldwide), then 3Com
shall have no obligation to grant such covenant under this Section 3.10(c).

         3.11 PALM COVENANT NOT TO SUE

                                     -10-
<PAGE>

                  (a) Palm irrevocably grants, on behalf of itself and its
Subsidiaries, at no charge, an immunity from suit to 3Com and its
Subsidiaries, and its or their direct or indirect customers and manufacturers
(subject to the restrictions set forth in the next sentence) for infringement
of any Palm Patent by any Current 3Com Product. The foregoing covenant with
respect to Third Party manufacturers (i) shall apply only when the portion of
the "have made" Current 3Com Product covered by the Palm Patents has been
designed or created by 3Com and/or one of 3Com's subcontractors (not the
Third Party manufacturer) who is not a direct competitor of Palm in the field
of the Current 3Com Product being designed or created and (ii) shall not
apply to (A) any methods used, or (B) any products or portions thereof that
have been manufactured or marketed by any Third Party prior to 3Com
furnishing the designs or creations to such Third Party. No immunity is
granted under the foregoing covenant by Palm, either directly or by
implication, estoppel or otherwise to any Third Parties acquiring Current
3Com Products from 3Com for the combination of such Current 3Com Products
with other items or for the use of such combination; provided, however, that
the foregoing covenant shall apply to the direct and indirect customers of
3Com for the combination of any such acquired Current 3Com Products with
other 3Com Products and their use in such combination where the acquired
Current 3Com Products have no other substantial noninfringing use aside from
the combination with other 3Com Products sold or otherwise transferred by
3Com directly or indirectly to such customer.

                  (b) The foregoing covenant shall continue with respect to
each Palm Patent, for the term of such Palm Patent.

                  (c) If 3Com, after the Separation Date, transfers all or
substantially all of its business or assets, or transfers a Subsidiary or
business unit, then regardless of whether such transfer is part of (i) an
asset sale to any Third Party, or (ii) a sale of shares or securities in 3Com
or a Subsidiary to a Third Party (in each case, any such Third Party shall be
referred to herein as a "Transferee"), then upon written request by 3Com and
the Transferee to Palm within sixty(60) days following the transfer, Palm
shall grant an immunity from suit to the Transferee under the same terms as
the covenant set forth in Section 3.11(a) and (b) above subject to the
following:

                                (i) the effective date of such covenant shall
be the effective date of transfer; and

                                (ii) the products and services of the
Transferee that are subject to such covenant shall be limited to the specific
Current 3Com Products in the transferred business that are (A) commercially
released as of the date of transfer or which, prior to the transfer, (B) were
planned for release within three (3) months from the date of transfer and
actually are commercially released within three (3) months from the date of
transfer and (C) for new versions of such specific Current 3Com Products
covered by clauses (i) or (ii) above, that have merely minor differences from
such Current 3Com Products with no additional features; and

                                (iii) the Palm Patents that are subject to
such covenant shall be limited to the Palm Patents that are entitled to a
First Effective Filing Date before the date of such transfer and, in the
event that the transfer is a transfer of a Subsidiary or business unit and
not all or substantially

                                     -11-
<PAGE>

all of 3Com's business or assets, then the Palm Patents that are subject to
such covenant shall be limited to the Palm Patents in the field of use of the
transferred Subsidiary or business; and

                                (iv) this Section 3.11(c) shall be excluded
from such covenant in any event and therefore, Palm shall have no obligation
to grant a covenant not to sue to any subsequent transferee;

                                (v) provided, however, that Palm shall have
no such obligation to grant such covenant unless the Transferee grants to
Palm and its customers and suppliers a covenant not to sue at no charge on
the following terms:

                                             (1) the effective date of such
covenant shall be the effective date of the transfer; and

                                             (2) the products and services of
Palm that are subject to such covenant shall be the Palm Products; and

                                             (3) the Patents of the
Transferee that are subject to such covenant shall be all the Patents owned
or controlled by the Transferee that are entitled to a First Effective Filing
Date before the date of such transfer and applications for such Patents
including without limitation any continuations, continuations-in-part,
divisions and substitutions; and

                                (vi) provided, further, that in the event
that Palm and any such Transferee are engaged in litigation, arbitration or
other formal dispute resolution proceedings covering Patent infringement
(pending in any court, tribunal, or administrative agency or before any
appointed or agreed upon arbitrator in any jurisdiction worldwide), then Palm
shall have no obligation to grant such covenant under this Section 3.11(c).

                             ADDITIONAL OBLIGATIONS

         4.1 ADDITIONAL OBLIGATIONS WITH REGARD TO ASSIGNED PATENTS.

                  (a) The parties will cooperate to effect a smooth transfer
of the responsibility for prosecution, maintenance and enforcement of the
Assigned Patents from 3Com to Palm. Until such transfer has been effected,
3Com agrees to continue the prosecution and maintenance of, and ongoing
litigation (if any) with respect to, the Assigned Patents (including payment
of maintenance fees), and to maintain its files and records relating to the
Assigned Patents using the same standard of care and diligence that it uses
with respect to 3Com's Patents. Palm will reimburse 3Com for all actual and
reasonable expenses (excluding the value of the time of 3Com employees) to
continue to prosecute and maintain the Assigned Patents after the Separation
Date until the transfer of

                                      -12-
<PAGE>

responsibility for the Assigned Patents has been completed and to continue
any such ongoing litigation. The parties shall agree on a case by case basis
on compensation, if any, of 3Com for the value of time of 3Com's employees as
reasonably required in connection with any such litigation. 3Com will provide
Palm with the originals or copies of its files relating to the Assigned
Patents upon such transfer or at such earlier time as the parties may agree.

                  (b) 3Com shall provide continuing reasonable support to
Palm with respect to the Assigned Patents, including by way of example the
following:

                                (i) executing all documents prepared by Palm
necessary for prosecution, maintenance, and litigation of the Assigned
Patents,

                                (ii) making available to Palm or its counsel,
inventors and other persons employed by 3Com for interviews and/or testimony
to assist in good faith in further prosecution, maintenance or litigation of
the Assigned Patents, including the signing of documents related thereto,

                                (iii) forwarding copies of all correspondence
sent and received concerning the Assigned Patents within a reasonable period
of time after receipt by 3Com, and

                                (iv) making all relevant documents in the
possession or control of 3Com and corresponding to the Assigned Patents, or
any licenses thereunder, available to Palm or its counsel.

Any actual and reasonable out-of-pocket expenses associated with any such
assistance shall be borne by Palm, expressly excluding the value of the time
of such 3Com employees; provided, however, that in the case of assistance
with litigation, the parties shall agree on a case by case basis on
compensation, if any, of 3Com for the value of the time of 3Com's employees
as reasonably required in connection with such litigation.

         4.2 ADDITIONAL OBLIGATIONS WITH REGARD TO GALAHAD PATENTS. Palm
shall provide continuing reasonable support to 3Com with respect to the
Galahad Patents, including by way of example the following:

                  (a) executing all documents prepared by 3Com necessary for
prosecution, maintenance, and litigation of the Galahad Patents,

                  (b) making available to 3Com or its counsel, inventors and
other persons employed by Palm for interviews and/or testimony to assist in
good faith in further prosecution, maintenance or litigation of the Galahad
Patents, including the signing of documents related thereto,

                  (c) forwarding copies of all correspondence sent and
received concerning the Galahad Patents within a reasonable period of time
after receipt by Palm, and

                                     -13-

<PAGE>

                  (d) making all relevant documents in the possession or control
of Palm and corresponding to the Galahad Patents, or any licenses thereunder,
available to 3Com or its counsel.

         Any actual and reasonable out-of-pocket expenses associated with such
assistance shall be borne by 3Com, expressly excluding the value of the time of
such Palm personnel; provided, however, that in the case of assistance with
litigation, the parties shall agree on a case by case basis on compensation, if
any, of Palm for the value of the time of Palm's employees as reasonably
required in connection with such litigation.

         4.3  STANDARDS BODIES. For a period of five (5) years from the
Separation Date, the parties agree to cooperate reasonably and in good faith
with each other with respect to the licensing of each party's Patents in the
context of Bluetooth related standards bodies, to the extent consistent with
each party's own business objectives.

         4.4  ASSIGNMENT OF PATENTS. 3Com shall not assign or grant any
rights under any of the Galahad Patents unless such assignment or grant is
made subject to the licenses granted in this Agreement.

         4.5  RECORDATION OF LICENSES.

                  (a) For any country, now or in the future, that requires the
express consent of all inventors or their assignees to the grant of licenses or
rights under Patents issued in such countries for joint inventions:

                               (i) each party shall give such consent, or
shall obtain such consent from its employees, its Subsidiaries or employees
of any of its Subsidiaries, as required to make full and effective any such
licenses and rights respecting any joint invention granted to a grantee
hereunder by such party; and

                               (ii) each party shall take steps that are
reasonable under the circumstances to obtain from Third Parties whatever
other consents are necessary to make full and effective such licenses and
rights respecting any joint invention purported to be granted by it
hereunder. If, in spite of such reasonable steps, such party is unable to
obtain the requisite consents from such Third Parties, the resulting
inability of such party to make full and effective its purported grant of
such licenses and rights shall not be considered to be a breach of this
Agreement.

                  (b) Each party agrees, without demanding any further
consideration, to execute (and to cause its Subsidiaries to execute) all
documents reasonably requested by the other party to effect recordation of the
license relationship between the parties created by this Agreement.

                                    ARTICLE 5

parties shall apply to any Confidential Information (as defined therein) which
is the subject matter of this Agreement.

                                   TERMINATION

         6.1  VOLUNTARY TERMINATION. By written notice to 3Com, Palm may
voluntarily terminate all or a specified portion of the licenses and rights
granted to it hereunder by 3Com. Such notice shall specify the effective date
of such termination and shall clearly specify any affected Patent, Patent
application, Invention Disclosure, product or service.

         6.2 SURVIVAL. Any voluntary termination of licenses and rights of
Palm under Section 6.1 shall not affect Palm's licenses and rights with
respect to any licensed product made or service furnished prior to such
termination, and shall not affect the licenses and rights granted to 3Com
hereunder.

         6.3  NO OTHER TERMINATION. Each party acknowledges and agrees that
its remedy for breach by the other party of the licenses granted to it
hereunder or of any other provision hereof, shall be, subject to the
requirements of Article 7, to bring a claim to recover damages subject to the
limits set forth in this Agreement and to seek any other appropriate
equitable relief, other than termination of the licenses or covenants not to
sue granted by it in this Agreement.

                                    ARTICLE 7
                               DISPUTE RESOLUTION

         7.1  MEDIATION. If a dispute, controversy or claim ("Dispute")
arises between the parties relating to the interpretation or performance of
this Agreement, or the grounds for the termination hereof, appropriate senior
executives (e.g. director or V.P. level) of each party who shall have the
authority to resolve the matter shall meet to attempt in good faith to
negotiate a resolution of the Dispute prior to pursuing other available
remedies. The initial meeting between the appropriate senior executives shall
be referred to herein as the "Dispute Resolution Commencement Date."
Discussions and correspondence relating to trying to resolve such Dispute
shall be treated as confidential information developed for the purpose of
settlement and shall be exempt from discovery or production and shall not be
admissible. If the senior executives are unable to resolve the Dispute within
thirty (30) days from the Dispute Resolution Commencement Date, and either
party wishes to pursue its rights relating to such Dispute, then the Dispute
will be mediated by a mutually acceptable mediator appointed pursuant to the
mediation rules of JAMS/Endispute within thirty (30) days after written
notice by one party to the other demanding non-binding mediation. Neither
party may unreasonably withhold consent to the selection of a mediator or the
location of the mediation. Both parties will share the costs of the mediation
equally, except that each party shall bear its own costs

                                     -15-

and expenses, including attorney's fees, witness fees, travel expenses, and
preparation costs. The parties may also agree to replace mediation with some
other form of non-binding or binding ADR.

         7.2  ARBITRATION. Any Dispute which the parties cannot resolve
through mediation within ninety (90) days of the Dispute Resolution
Commencement Date, unless otherwise mutually agreed, shall be submitted to
final and binding arbitration under the then current Commercial Arbitration
Rules of the American Arbitration Association ("AAA"), by three (3)
arbitrators in Santa Clara County, California. Such arbitrators shall be
selected by the mutual agreement of the parties or, failing such agreement,
shall be selected according to the aforesaid AAA rules. The arbitrators will
be instructed to prepare and deliver a written, reasoned opinion stating
their decision within thirty (30) days of the completion of the arbitration.
The prevailing party in such arbitration shall be entitled to expenses,
including costs and reasonable attorneys' and other professional fees,
incurred in connection with the arbitration (but excluding any costs and fees
associated with prior negotiation or mediation). The decision of the
arbitrator shall be final and non-appealable and may be enforced in any court
of competent jurisdiction. The use of any ADR procedures will not be
construed under the doctrine of laches, waiver or estoppel to adversely
affect the rights of either party.

         7.3 COURT ACTION. Any Dispute regarding the following is not
required to be negotiated, mediated or arbitrated prior to seeking relief
from a court of competent jurisdiction: breach of any obligation of
confidentiality; infringement, misappropriation, or misuse of any
intellectual property right; any other claim where interim relief from the
court is sought to prevent serious and irreparable injury to one of the
parties or to others. However, the parties to the Dispute shall make a good
faith effort to negotiate and mediate such Dispute, according to the above
procedures, while such court action is pending.

         7.4  CONTINUITY OF SERVICE AND PERFORMANCE. Unless otherwise agreed
in writing, the parties will continue to provide service and honor all other
commitments under this Agreement during the course of dispute resolution
pursuant to the provisions of this Article 7 with respect to all matters not
subject to such dispute, controversy or claim.

                                    ARTICLE 8
                             LIMITATION OF LIABILITY

         IN NO EVENT SHALL EITHER PARTY OR ITS SUBSIDIARIES BE LIABLE TO THE
OTHER PARTY OR ITS SUBSIDIARIES FOR ANY SPECIAL, CONSEQUENTIAL, INDIRECT,
INCIDENTAL OR PUNITIVE DAMAGES OR LOST PROFITS, HOWEVER CAUSED AND ON ANY THEORY
OF LIABILITY (INCLUDING NEGLIGENCE) ARISING IN ANY WAY OUT OF THIS AGREEMENT,
WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES;
PROVIDED, HOWEVER, THAT THE FOREGOING LIMITATIONS SHALL NOT LIMIT DAMAGES FOR
INFRINGEMENT AVAILABLE TO EITHER PARTY UNDER APPLICABLE LAW IN THE EVENT OF
BREACH BY THE OTHER PARTY OF SECTIONS 3.1, 3.2, 3.3 OR 3.5(a) OR FOR
INFRINGEMENT OF ANY INTELLECTUAL PROPERTY RIGHTS NOT LICENSED OR COVENANTED
HEREIN AND

                                     -16-
<PAGE>

SHALL NOT LIMIT EACH PARTY'S OBLIGATIONS EXPRESSLY ASSUMED IN EXHIBIT J OF
THE MASTER SEPARATION AND DISTRIBUTION AGREEMENT; PROVIDED FURTHER THAT THE
EXCLUSION OF PUNITIVE DAMAGES SHALL APPLY IN ANY EVENT.

                                    ARTICLE 9
                            MISCELLANEOUS PROVISIONS

         9.1  DISCLAIMER. EACH PARTY ACKNOWLEDGES AND AGREES THAT ALL PATENTS
AND ANY OTHER INFORMATION OR MATERIALS LICENSED OR PROVIDED HEREUNDER ARE
LICENSED OR PROVIDED ON AN "AS IS" BASIS AND THAT NEITHER PARTY NOR ANY OF
ITS SUBSIDIARIES MAKES ANY REPRESENTATIONS OR EXTENDS ANY WARRANTIES
WHATSOEVER, EXPRESS, IMPLIED OR STATUTORY, WITH RESPECT THERETO INCLUDING
WITHOUT LIMITATION ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
PARTICULAR PURPOSE, TITLE, ENFORCEABILITY OR NON-INFRINGEMENT. Without
limiting the generality of the foregoing, neither party nor any of its
Subsidiaries makes any warranty or representation as to the validity and/or
scope of any Patent licensed by it to the other party hereunder or any
warranty or representation that any manufacture, use, importation, offer for
sale or sale of any product or service will be free from infringement of any
Patent or other intellectual property right of any Third Party.

         9.2  NO IMPLIED LICENSES. Nothing contained in this Agreement shall
be construed as conferring any rights by implication, estoppel or otherwise,
under any intellectual property right, other than the rights expressly
granted in this Agreement with respect to the Galahad Patents and Assigned
Patents. Neither party is required hereunder to furnish or disclose to the
other any technical or other information except as specifically provided
herein.

         9.3  INFRINGEMENT SUITS. Neither party shall have any obligation
hereunder to institute any action or suit against Third Parties for
infringement of any Patent or to defend any action or suit brought by a Third
Party which challenges or concerns the validity of any Patent. Unless the
parties otherwise agree in writing, neither party shall have any right to
institute any action or suit against Third Parties for infringement of any
Patent owned by the other party.

         9.4  NO OTHER OBLIGATIONS. NEITHER PARTY ASSUMES ANY
RESPONSIBILITIES OR OBLIGATIONS WHATSOEVER, OTHER THAN THE RESPONSIBILITIES
AND OBLIGATIONS EXPRESSLY SET FORTH IN THIS AGREEMENT OR A SEPARATE WRITTEN
AGREEMENT BETWEEN THE PARTIES. Without limiting the generality of the
foregoing, neither party, nor any of its Subsidiaries is obligated to (i)
file any Patent application, or to secure any Patent or Patent rights, (ii)
to maintain any Patent in force, or (iii) provide any technical assistance,
except for the obligations expressly assumed in this Agreement.

Distribution Agreement and the other Ancillary Agreements (as defined in the

agreements and understandings with respect to the subject matter hereof and

this Agreement shall govern.

         9.6  GOVERNING LAW. This Agreement shall be construed in accordance
with and all Disputes hereunder shall be governed by the laws of the State of
California, excluding its conflict of law rules and the United Nations

by first class mail. All notices shall be deemed to have been given and
received on the earlier of actual delivery or three (3) days from the date of
postmark.

         9.9  NONASSIGNABILITY. Neither party may, directly or indirectly, in
whole or in part, whether by operation of law or otherwise, assign or
transfer this Agreement, without the other party's prior written consent, and
any attempted assignment, transfer or delegation without such prior written
consent shall be voidable at the sole option of such other party.
Notwithstanding the foregoing, each party (or its successive assignees or
transferees hereunder) may, without such consent, assign or transfer this
Agreement, to a Person that succeeds to all or substantially all of its
business or assets of such party as long as such Person agrees to accept all
of the terms set forth herein; provided, however, that the licenses and
covenants not to sue set forth in Article 3 may not be assigned or
transferred in any event (except in the case of a reincorporation of such
party in another state); and provided, further, that the prohibition on
assignment or transfer of the licenses and covenants not to sue set forth in
Article 3 shall not limit 3Com's or Palm's obligations in Sections 3.7,
3.10(c) and 3.11(c) to grant licenses and/or covenants not to sue to a
Transferee. Without limiting the foregoing, this Agreement will be binding
upon and inure to the benefit of the parties and their permitted successors
and assigns.

         9.10  SEVERABILITY. If any term or other provision of this Agreement
is determined by a court, administrative agency or arbitrator to be invalid,
illegal or incapable of being enforced by any rule of law or public policy,
all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner materially
adverse to either party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties
hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible in an acceptable
manner to the end that the transactions contemplated hereby are fulfilled to
the fullest extent possible.

         9.11  FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE. No
failure or delay on the part of either party hereto in the exercise of any
right hereunder shall impair such right or be construed to be a waiver of, or
acquiescence in, any breach of any representation, warranty or agreement
herein, nor shall any single or partial exercise of any such right preclude
other or further exercise thereof or of any other right. All rights and
remedies existing under this Agreement are cumulative to, and not exclusive
of, any rights or remedies otherwise available.

         9.12  AMENDMENT. No change or amendment will be made to this
Agreement except by an instrument in writing signed on behalf of each of the
parties to such agreement.

         9.13  COUNTERPARTS. This Agreement, including the Ancillary
Agreement and the Exhibits and Schedules hereto and thereto and the other
documents referred to herein or therein, may be executed in counterparts,
each of which shall be deemed to be an original but all of which shall
constitute one and the same agreement.
