(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.

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.

(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- 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). ARTICLE 4 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- 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- (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 CONFIDENTIALITY -14- The terms of the Master Confidential Disclosure Agreement between the parties shall apply to any Confidential Information (as defined therein) which is the subject matter of this Agreement. ARTICLE 6 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.

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.
