                         SECOND AMENDMENT TO CONVERTIBLE
                          SUBORDINATED PROMISSORY NOTE

     This Second Amendment is entered into as of January 18, 2002, by and
between Ross J. Pollack ("Payee") and DoveBid, Inc., a Delaware corporation (the
"Company"). This Amendment amends the terms and conditions of that certain
Convertible Subordinated Promissory Note issued by the Company to Payee on March
2, 2000 in the principal amount of $1,375,000 (the "Note").

     Whereas, Payee and the Company desire to amend the Note on the terms and
conditions set forth below in order to correct a typographical error;

     Now, therefore, in consideration of the foregoing and for other good and
valuable consideration (receipt and sufficiency of which is mutually
acknowledged), the parties agree as follows:

     1.   The first paragraph of the Note is hereby amended to read as follows.

     "DoveBid, Inc., a Delaware corporation (the "Company"), with offices at
     1241 East Hillsdale Blvd., Foster City, CA 94404, for value received,
     promises to pay to the order of Ross J. Pollack ("Payee") at such address
     as Payee may designate, One Million Three Hundred and Seventy Five Thousand
     Dollars and No Cents ($1,375,000), plus simple interest thereon calculated
     from the date hereof until paid at an annual rate of 6.45%, which is equal
     to the minimum rate established pursuant to Section 1274(d) of the Internal
     Revenue Code of 1986, as amended, as of the date hereof, compounded
     annually; provided that if this Note shall not have converted into
     Conversion Stock (as defined below) by March 2, 2002, then on and after
     such date accrued interest with respect to principal then outstanding under
     this Note for each three month period after March 2, 2002 shall be payable
     at the end of each such three month period thereafter. Principal and
     accrued interest will be due and payable in lawful money of the United
     States in full on March 2, 2005 (the "Maturity Date"), unless this Note or
     any portion thereof shall have been previously paid by the Company or
     converted pursuant to Section 2 below, in which case the portion of the
     outstanding principal under this Note that was converted and all accrued
     but unpaid interest thereon shall be satisfied in full by virtue of such
     conversion and the issuance and delivery of fully paid and non-assessable
     shares of Conversion Stock to the holder of this Note as set forth in
     Section 2 below. Payments by the Company shall be applied first to any and
     all accrued interest through the payment date and second to the principal
     remaining due hereunder."

     2.   Effect of Amendment. This Amendment will be effective as of the date
first set forth above, upon execution of this Amendment by the Company and
Payee. This Amendment

may be executed in any number of counterparts, each of which shall be deemed an
original and all of which, taken together, will constitute one and the same
Amendment. Except as expressly provided above, the terms and conditions of the
Note remain in full force and effect, unmodified, as of the date hereof.

     In Witness Whereof, Payee and the Company have executed this Amendment to
Convertible Subordinated Promissory Note, in the case of the Company by a person
duly authorized to do so.
