ARTICLE 12. VALIDITY AND INFRINGEMENT

(a)  SHARP represents and warrants to UTSTARCOM and HUTS that the KNOW-HOW and
     INTELLECTUAL PROPERTY RIGHTS are the original work of SHARP in each and all
     aspects.

(b)  UTSTARCOM shall have no right to apply for registration of any intellectual
     property rights in the TERRITORY or any other country with regard to the
     KNOW-HOW and other technical information made available or furnished by
     SHARP hereunder, or to apply itself as the registered licensee or user of
     any of the INTELLECTUAL PROPERTY RIGHTS.
     UTSTARCOM shall cause HUTS and EASTCOM to abide by same obligation above
     of UTSTARCOM.

(c)  UTSTARCOM shall cause HUTS and EASTCOM to promptly notify UTSTARCOM and
     accordingly UTSTARCOM shall promptly notify SHARP in addition to its own
     awareness, of any and all infringements, imitations or illegal use of the
     INTELLECTUAL PROPERTY RIGHTS and of any statements or action made or done
     by any person, firm or corporation disputing or impairing SHARP's interest
     in and title to any of the INTELLECTUAL PROPERTY RIGHTS.

(d)  Whenever in the opinion of SHARP, any action is necessary or advisable to
     insure the protection or prevention against such infringements, imitations
     or illegal use of any INTELLECTUAL PROPERTY RIGHTS, (i) SHARP may take any
     action in the courts, administrative agencies or otherwise, and (ii) upon
     the request of SHARP and subject to and within the scope of SHARP's
     agreement to reimburse UTSTARCOM for any expenses to be incurred by
     UTSTARCOM, UTSTARCOM shall or shall cause HUTS to take whatever action is
     deemed necessary by SHARP to insure such protection or prevention.
     SHARP shall not be obligated to take any action against such infringements,
     imitations or illegal use and shall have no liability to UTSTARCOM, HUTS
     and EASTCOM for failure to do so. UTSTARCOM shall or shall cause HUTS to
     take no action with respect to any infringement, imitation or illegal use
     of any INTELLECTUAL PROPERTY RIGHTS unless requested by SHARP to do so.
     In any circumstances all the proceeds or recovery of any damages awarded
     in such action shall accrue to SHARP.

(e)  In the event, however, that UTSTARCOM (or HUTS or EASTCOM, as the case may
     be) is threatened or involved in any infringement or other like litigation
     in the TERRITORY, by reason of its exercise of rights acquired under this
     Agreement, SHARP will render to UTSTARCOM (or HUTS or EASTCOM, as the case
     may be) such assistance as SHARP, in its sole discretion, deems appropriate
     in defending such litigation or threatened litigation at the expense of
     UTSTARCOM. SHARP shall, in view of that the amounts of Royalties mentioned
     in Article 10 is a consideration only for the INTELLECTUAL PROPERTY RIGHTS,
     the KNOW-HOW and other technical information necessary for the assembly
     and manufacture of the PRODUCTS, not be held responsible by UTSTARCOM (or
     HUTS or EASTCOM, as the case may be) (i) for infringement of any patent,
     utility

     model right, design, copyright or other intellectual property rights of
     third parties, or damages or cost involved in any proceeding based on such
     infringements, (ii) for the validity of any INTELLECTUAL PROPERTY RIGHTS
     granted hereunder, or the inability of HUTS (or EASTCOM, as the case may
     be) to use such INTELLECTUAL PROPERTY RIGHTS or KNOW-HOW because of any
     patent, utility model right, design, copyright or other intellectual
     property rights of third parties or (iii) for any additional royalties or
     obligations incurred by UTSTARCOM (or HUTS or EASTCOM, as the case may be)
     because of any patent, utility model right, design, copyright or other
     intellectual property rights of third parties.

(f)  In the event that SHARP becomes or is made, whether by judicial
     declaration, settlement, agreement of the relevant parties or in any other
     manner, responsible for or liable to pay damages, costs, royalties or any
     other compensation or consideration or to perform any other obligation,
     whether in respect of past, present or future acts or circumstances (the
     "Obligation"), to a third party with respect to or arising out of an
     infringement or alleged infringement of any patent, utility model right,
     design, copyright or any other intellectual property right of the third
     party in the TERRITORY resulting from the assembly and manufacture by
     EASTCOM or sale or distribution by HUTS of the PRODUCTS hereunder,
     UTSTARCOM shall or shall cause HUTS and EASTCOM to indemnify and hold
     harmless SHARP in full, or in part as may be determined by SHARP in its
     sole discretion, with respect to the Obligation to be paid to or performed
     for the benefit of the third party. SHARP may, in its sole discretion,
     determine the manner in which such indemnification by UTSTARCOM (or HUTS or
     EASTCOM, as the case may be) shall be made. In exercising its discretion
     pursuant to this paragraph, SHARP shall give due consideration to the
     contribution of each party (including HUTS and EASTCOM, as the case may
     be), the particular circumstances of the Obligation and the profit and
     other benefits received by each party (including HUTS and EASTCOM, as the
     case may be) hereto in respect of the subject matter of this Agreement.

     and/or any other agreement concluded under or in connection with this
     Agreement by sending a written notice to the first party by registered air
     mall:

     i)   If either party hereto continues in default of any material obligation

          party requesting the party in default to remedy such default;

     ii)  If either party hereto is subjected to compulsory execution, public
          auction, coercive collection for its arrearage of taxes or public
          imposts, or suspension of business by public authorities, or
          appointment of any receiver or trustee of itself or any substantial

          against either party for bankruptcy, corporate arrangement or
          commencement of corporate reorganization, or if either party hereto
          files voluntarily against it an application or petition for
          bankruptcy, corporate arrangement or commencement of corporate
          reorganization or composition, or if either party hereto adopts a
          resolution for discontinuance of its business or for a substantial
          decrease of its capital or for dissolution or merger into another

          opinion of the other party would be detrimental to its interests; or

     iv)  If there is any other material cause justifying either party to
          terminate this Agreement, such as material and irreparable injury to
          goodwill or reputation by the other party, commission by other party
          of a fraud on or betrayal of confidence in or criminal act against the
          first party, disclosure or divulgence by the other party of the first

     may be) defaults in the due performance of its obligations hereunder or
     under any agreement made pursuant hereto or in respect hereto, or in the
     event that this Agreement is terminated pursuant to paragraph (a) of this
     Article, then the other party or the party despatching a notice of
