d) 
      The Board of Directors of U.S. Auto Parts Network, Inc. has appointed Barry
      Phelps as a Class III director, effective September 20, 2007.  He will
      serve until reelection at the Annual Stockholders' Meeting in June
      2009.
Information
      regarding committees of the registrant's Board of Directors that Mr. Phelps will
      serve on had not been determined at the time of filing this Current Report
      on
      Form 8-K.  Once determined, the committee assignment(s) will be
      disclosed by the registrant in a Current Report on Form 8-K.
There
      are
      no relationships or related transactions to be disclosed under Item 404(a)
      of
      Regulation S-K regarding certain relationships and related transactions between
      the registrant and Mr. Phelps.
There
      are
      no arrangements or understandings pursuant to which Mr. Phelps was selected
      as a
      director.  Beginning January 2007, each non-employee director, which
      now includes Mr. Phelps, will be paid a fee of $25,000 per year for his or
      her
      service as a director. Members of the audit committee, the compensation
      committee, and the nominating and corporate governance committee will each
      receive an additional $7,500, $5,000 and $2,500, respectively, per year for
      his
      or her service on such committee. The chairpersons of the audit committee,
      the
      compensation committee, and the nominating and corporate governance committee
      will receive $15,000, $7,500 and $5,000, respectively, per year for his or
      her
      service on such committee. Any non-employee director will be granted an option
      to purchase 45,000 shares of the registrant's common stock on the date of his or
      her initial election to the board of directors. In addition, on the date of
      each
      annual stockholders meeting, each person who has served as a non-employee member
      of the board of directors for at least six months before the date of the
      stockholder meeting will be granted a stock option to purchase 20,000 shares
      of
      common stock. These options will have an exercise price per share equal to
      the
      fair market value of the registrant's common stock on the date of grant and will
      vest over a three year period, subject to the director's continuing service on
      the board of directors. The term of each option granted to a non-employee
      director shall be ten years. These options will be granted under the
      registrant's 2007 Omnibus Incentive Plan.
