                    CONVERTIBLE SUBORDINATED PROMISSORY NOTE

$1,375,500                                                         March 2, 2000

          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 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. Principal and accrued interest will be due and
payable in lawful money of the United States in full on the three year
anniversary of the date of this Note (the "Maturity Date"), unless this Note
shall have been previously converted pursuant to Section 2 below, in which case
all outstanding principal under this Note and all accrued 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.

          The following is a statement of the rights of the holder of this Note
and the conditions to which this Note is subject, and to which the holder
hereof, by the acceptance of this Note, agrees:

          1.  Definitions.  As used in this Note, the following terms, unless
              -----------
the context otherwise requires, have the following meanings:
<PAGE>

          1.1  "Company" includes any corporation or other entity which succeeds
to or assume the obligations of the Company under this Note.

          1.2  "Conversion Stock" shall mean shares of Common Stock of the
Company of the same class of common stock that is registered by the Company
pursuant to an Initial Public Offering.

          1.3  "Conversion Price" shall mean the price per share that is the
exact middle of the price range stated in the Company's final amended
registration statement on Form S-1, Form SB-1 or a similar successor form
pertaining to an Initial Public Offering that closes on before the Maturity
Date.  No conversion shall occur and there is therefore no Conversion Price with
respect to an Initial Public Offering that closes after the Maturity Date.

          1.4  "Noteholder," "holder," or similar terms, when the context refers
to a holder of this Note, shall mean any person who shall at the time be the
registered holder of this Note.

          1.5  "Initial Public Offering" shall mean the closing of a sale of
Common Stock pursuant to a registration statement on Form S-1, Form SB-1 or SB-2
(or any similar or successor form) under the Securities Act of 1933, as amended,
for an underwritten initial public offering.

          1.6  "Subordination Agreement" shall mean the Subordination Agreement
attached hereto as Annex A and incorporated by reference herein.
                   -------

     2.  Conversion.
         ----------

         2.1  Mandatory Conversion.  This Note and all of the outstanding
              --------------------
principal and accrued and unpaid interest on and under this Note shall be
converted into Conversion Stock at the Conversion Price immediately prior to the
first closing of an Initial Public Offering before the Maturity Date.  For
informational purposes, the Company shall provide the Noteholder with written
notice (at the most recent address for the Noteholder provided to the Company by
the Noteholder in writing) (i) within seven days after it files with the
Securities and Exchange Commission any registration statement on Form S-1, Form
SB-1 or Form SB-2 (or any similar or successor form) for an Initial Public
Offering, and (ii) reasonably promptly following the closing of an Initial
Public Offering. Conversion as described in this Section 2.1 shall occur only
upon the closing of an Initial Public Offering, provided that (i) upon the
closing of an Initial Public Offering, the conversion shall be deemed to have
occurred immediately prior to the first closing of such Initial Public Offering,
and (ii) as a condition precedent or condition subsequent to conversion (the
election between which type of condition shall be the Company's sole election in
the Company's sole discretion), the Noteholder must surrender this Note for
conversion at the principal office of the Company. Incident to any conversion,
the Conversion Stock will have those rights and privileges, and be subject to
those restrictions, of the shares of Common Stock as set forth in the Company's
Certificate of Incorporation, and the Noteholder will receive the rights and be
subject to the obligations applicable to the purchasers of Common Stock,
provided that the sale restriction specified in Section 2.5 below shall apply to
the Conversion Stock.  This
<PAGE>

Note shall not be convertible and shall not be converted into Conversion Stock
if there is not an Initial Public Offering on or before the Maturity Date.

          2.2  No Fractional Shares.  No fractional shares will be issued on
               --------------------
conversion of this Note.  If on any conversion of this Note a fraction of a
share results, the Company will pay the cash value of that fractional share,
calculated on the basis of the applicable Conversion Price.

          2.3  Reservation of Stock.  Prior to any conversion of this Note
               --------------------
pursuant to Section 2.1 above, the Company will take such corporate action and
obtain such government consents and approvals as may, in the reasonable opinion
of its counsel, be necessary to authorize the issuance of a sufficient number of
shares of Conversion Stock into which this Note is to convert pursuant to
Section 2.1 above.

          2.4  Fully Paid Shares; Certificates.  All shares of Conversion Stock
               -------------------------------
issued upon the conversion of this Note shall be validly issued, fully paid and
non-assessable.  The certificates representing the shares of Conversion Stock
issued upon conversion hereof shall be delivered to the holder against surrender
of this Note.  The holder, by accepting this Note, undertakes and agrees to
accept such shares of Conversion Stock in full satisfaction of the outstanding
principal and accrued interest thereon in accordance with the terms of this
Note.  Anything to the contrary in this Note notwithstanding, the Company's
obligation to issue shares of Conversion Stock to any holder of this Note is
expressly conditioned upon compliance of such issuance with applicable federal
and state securities laws without registration or other qualification
thereunder.

          2.5  Restriction on Sale.  Upon and following any conversion pursuant
               -------------------
to this Section 2, no holder of any Conversion Stock shall effect any sale or
distribution of any of the Conversion Stock (which shall include any and all
voting securities received by such holder as or in connection with a stock
dividend, stock split or other recapitalization or similar distribution on or in
respect of the Conversion Stock) or any of the Company's other equity
securities, or of any securities convertible into or exchangeable for such
securities, during the period beginning on the closing of the Initial Public
Offering and ending 180 days after such closing.  [Ross Note only:  Furthermore,
the Payee agrees that he shall not effect sales or distributions of the
Conversion Stock (which shall include any and all voting securities received by
such holder as or in connection with a stock dividend, stock split or other
recapitalization or similar distribution on or in respect of such Conversion
Stock) or the Company's other equity securities, or of any securities
convertible into or exchangeable for such securities, which sales or other
distributions would constitute: (a) more than 0% of the Conversion Stock or such
other securities prior to the six month anniversary of the issuance of the
Conversion Stock; (b) more than 25% of the Conversion Stock or such other
securities on or following the six month anniversary of the issuance of the
Conversion Stock but prior to the twelve month anniversary of the issuance of
the Conversion Stock; (c) more than 50% of the Conversion Stock or such other
securities on or following the twelve month anniversary of the issuance of the
Conversion Stock but prior to the 24 month anniversary of the issuance of the
Conversion Stock; and (d) more than 75% of the Conversion Stock or such other
securities on or following the 24 month anniversary of the issuance of the
Conversion Stock but prior to the 36 month anniversary of the issuance of the
Conversion Stock. On or following the 36 month anniversary of the issuance of
the Conversion Stock, such
<PAGE>

restrictions shall no longer apply.] The certificate(s) representing the shares
of Conversion Stock issued upon the conversion of this Note shall be legended to
reflect such restrictions on sale.

          2.6  No Rights or Liabilities as Shareholder.  This Note does not by
               ---------------------------------------
itself entitle the Noteholder to any voting rights or other rights as a
shareholder of the Company.  In the absence of conversion of this Note, no
provisions of this Note, and no enumeration herein of the rights or privileges
of the holder shall cause such holder to be a shareholder of the Company for any
purpose by virtue hereof.

          2.7  No Other Conversion.  The conversion described in this Section 2
               -------------------
shall constitute the sole methods by which this Note will convert.

     3.   Subordination.  This Note and the indebtedness evidence by this
          -------------
Note are subordinated to the prior payment in full of all or substantially all
other indebtedness of the Company pursuant to the terms of a Subordination
Agreement in the form attached hereto as Annex A and incorporated herein by
                                         -------
reference.

     4.   Prepayment.  This Note may be prepaid, in its entirety (including
          ----------
the principal sum and interest accrued to the date of payment) without penalty
or premium at any time after September 1, 2000; provided that prepayment cannot
take place after the Company has filed with the Securities and Exchange
Commission a registration statement on Form S-1, Form SB-1 or Form SB-2 (or any
similar or successor form) for an Initial Public Offering and for so long as any
such registration statement remains pending.

     5.   Usury Savings Clause.  The Company and the Noteholder intend to
          --------------------
comply at all times with applicable usury laws.  If at any time such laws would
render usurious any amounts due under this Note under applicable law, then it is
the Company's and the Noteholder's express intention that the Company not be
required to pay interest on this Note at a rate in excess of the maximum lawful
rate, that the provisions of this Section 5 shall control over all other
provisions of this Note which may be in apparent conflict hereunder, that such
excess amount shall be immediately credited to the principal balance of this
Note (or, if this Note has been fully paid, refunded by the Noteholder to the
Company), and the provisions hereof shall immediately be reformed and the
amounts thereafter decreased, so as to comply with the then applicable usury
law, but so as to permit the recovery of the fullest amount otherwise due under
this Note.

     6.   General Provisions.

              5. Usury Savings Clause. The Company and the Noteholder intend to
                 --------------------
comply at all times with applicable usury laws. If at any time such laws would
render usurious any amounts due under this Note under applicable law, then it is
the Company's and the Noteholder's express intention that the Company not be
required to pay interest on this Note at a rate in excess of the maximum lawful
rate, that the provisions of this Section 5 shall control over all other
provisions of this Note which may be in apparent conflict hereunder, that such
excess amount shall be immediately credited to the principal balance of this
Note (or, if this Note has been fully paid, refunded by the Noteholder to the
Company), and the provisions hereof shall immediately be reformed and the
amounts thereafter decreased, so as to comply with the then applicable usury
law, but so as to permit the recovery of the fullest amount otherwise due under
this Note.
