Exhibit 10.39

FIRST AMENDMENT TO SUBLEASE

      THIS AMENDMENT is entered into effective as of the 14th day of March, 2003
(the “Effective Date”), between At Road, Inc., (hereinafter “Sublessor”) and
Athena Semiconductor, Inc., (hereinafter called “Sublessee”).

WITNESSETH:

      WHEREAS, the parties have previously entered into a written Sublease (the
“Sublease”), dated February 21, 2002, for sublease of a portion of the premises
located at 47358 Fremont Blvd., Fremont, CA 94538 (hereinafter the “Premises”);
and

      WHEREAS, the parties wish to amend the terms of the Sublease, pursuant to
the terms hereof, such amendment(s) to become effective as of the Effective
Date.

      NOW THEREFORE, in consideration of the mutual benefits to be conferred
hereunder and of the mutual promises and conditions herein contained, the
receipt, adequacy, and sufficiency of which are hereby acknowledged, the parties
agree as follows:

        1.     The above and foregoing premises are incorporated by reference.  
        2.     The Term of the Sublease (as such term set forth in Section 5 of
the Sublease and is used throughout the Sublease) shall be extended for a period
of one (1) year from the date that such Term would have otherwise expired, so
that such Term (as amended hereby) shall end on March 14, 2004, unless otherwise
sooner terminated in accordance with the provisions of the Subleases.          
3.     Section 6.1 of the Sublease shall be revised such that minimum rent (as
such minimum rent is referenced in the Sublease) shall be an amount equal to
Three Thousand Dollars ($3,000) per month (the “Revised Minimum Rent”). Such
Revised Minimum Rent shall be due and payable by Sublessee in advance on the
first day of each month beginning after the Effective Date of this Amendment and
extending through the Term (as amended by Section 2 of this Amendment), to such
address and pursuant to such other terms as may be found in the Sublease.    
      4.     Section 6.2 of the Sublease shall be revised such that Sublessee
shall be liable for additional rent during each month of the Term (beginning on
the Effective Date of this Amendment) in the amount of twenty percent (20%) of
the Operating Costs (as such term is defined in Section 6.2 of the Sublease),
which is estimated to be the sum of Six Hundred Dollars ($600) per month.    
      5.     The parties’ respective obligations with respect to the Amendment
are specifically conditioned upon obtaining the written consent from Prologis
Limited Partnership, lessor of the Premises, below. In the event the parties
fail to obtain such written consent, this Amendment shall be deemed null and
void, and of no force and effect.

and authority to bind the parties hereto and to commit each financially. This
Amendment shall not be deemed “accepted” until it is executed by a

CONSENT BY LANDLORD TO SUBLEASE

      The undersigned, as Landlord under that certain Lease dated August 3, 2000
and amended on March 8, 2001 with At Road, Inc., a Delaware corporation
(“Sublandlord”) for certain premises at
47358 - 47370 Fremont Boulevard in Fremont, CA (the “Prime Lease”), hereby
consents to the entering into of the foregoing First Amendment to Sublease dated
March 13, 2003 (“Sublease”) between Sublandlord, as sublessor, and Athena
Semiconductor, Inc., a Delaware corporation, as subtenant (“Subtenant”), upon
the express understandings and conditions that:

  a. Landlord neither approves nor disapproves the terms, conditions and
agreements contained in the Sublease (all of which shall be subordinate and
subject at all times to the terms, covenants and conditions of the Prime Lease)
and assumes no liability or obligation of any kind whatsoever on account of
anything contained in the Sublease;

  b. By executing this consent, Landlord shall not be deemed to have waived any
rights under the Prime Lease nor shall Landlord be deemed to have waived
Sublandlord’s obligations to obtain any required consents under the Prime Lease
(other than consent to the Sublease itself);

  c. Notwithstanding anything in the Sublease to the contrary, Sublandlord shall
be and continue to remain liable for the payment of rent and the full and prompt
performance of all of the obligations of Tenant under and as set forth in the
Prime Lease. Per paragraph 12 of the Master Lease, Sublandlord shall also be
bound and obligated to the terms and conditions set forth in regard to
Tenant-Made alterations and Trade Fixtures. In regard to the tenant improvements
noted on Exhibit B, Landlord reserves the right to have Sublandlord remove these
alterations at the expiration of the lease term.

  d. Nothing contained in the Sublease shall be taken or construed to in any way
modify, alter, waive or affect any of the terms, covenants or conditions
contained in the Prime Lease, or be deemed to grant Subtenant any privity of
contract with Landlord, or require Landlord to accept any payments from
Subtenant on behalf of Sublandlord;

  e. The Sublease shall be deemed and agreed to be a sublease only and not an
assignment and there shall be no further subletting or assignment of all or any
portion of the premises demised under the Prime Lease (including the premises
demised by the foregoing Sublease) except in accordance with the terms and
conditions of the Prime Lease; and

  f. If Landlord terminates the Prime Lease as a result of a default by
Sublandlord thereunder, the Sublease shall automatically terminate concurrently,
therewith unless Landlord elects in writing to keep the Sublease in full force
and effect in which case the Sublease shall become and be deemed to be a direct
indenture of lease between Landlord and Subtenant.
