     This Amendment is entered into as of August 7, 2000 by and among DoveBid,
Inc., a Delaware Corporation (the "Company"), and the "Investors" who are
parties to that certain Series C Preferred Stock Purchase Agreement, dated as of

11,235,955 additional shares of Series C Preferred Stock (the "Additional

     Whereas, the Company has requested that the Investors amend the Agreement,
as well as the agreements entered into by the parties thereto in connection with
the Agreement, in order to extend the closing period and to increase the number
of shares purchasable thereunder, so that additional shares of Series C
Preferred Stock may be sold pursuant to the Agreement and related agreements;

the Company and Investors who are to purchase a majority of the Shares at the
First Additional Closing and, such date, as it may be so extended, referred to
as the "Termination Date"), the stock certificates and other documents to have
been delivered at the First Additional Closing shall be returned to the Company,

             GLOBALCENTER Master Service Agreement No. OWP 00001
================================================================================

        This Master Services Agreement (this "Agreement") is entered into as
the 20th day of April 1998 ("Effective Date") by and between the entity
indicated on the Services Order Form attached hereto, with an office at the
address listed on the Services Order Form, ("Client"), and GlobalCenter, Inc.,
a corporation with offices at___________________________________________________
________________________________________________________________________________
("GlobalCenter"), and describes the terms and conditions pursuant to which
GlobalCenter shall license to Client certain Software and provide certain
Services (as defined below).

        In consideration of the mutual promises and upon the terms and
conditions set forth below, the parties agree as follows:

1.      NATURE OF AGREEMENT.  This is an Agreement for the provision by
GlobalCenter of Internet connectivity services (the "Bandwidth"), the lease of
equipment to provide such services (the "Hardware"), the availability of space
to store and operate such Hardware ("Space") and the licensing of software to
provide such Services (the "Software"), together comprising an Internet
connectivity and collocation package to be provided by GlobalCenter under this
Agreement (together, the "Services").

2.      SERVICE ORDERS

2.1.    Orders.  Client may issue one or more service orders describing the
Bandwidth, Space, Hardware, and Software that Client desires ("Service
Order"). Each Service Order will set forth the prices, initial term of
Services and other information in the form set forth in the Service Order
Form. No Service Order shall be effective until accepted by GlobalCenter. All
Service Orders will be subject to the terms and conditions of this Agreement,
and the terms of this Agreement shall supersede any terms and conditions which
may appear on Client's order form, or purchase order.

2.2.    Cancellation.  In the event that Client cancels or terminates a
Service Order at any time for any reason whatsoever other than expiration of
a Service Order or a Service Interruption (as defined below), Client agrees to
pay GlobalCenter as a cancellation fee all Monthly Recurring Charges specified
in the Service Order for the balance of the term therefor, which shall become
due and owing as of the effective date of cancellation or termination.

2.3.    IP Addresses.  GlobalCenter may assign on a temporary basis a
reasonable number of Internet Protocol Addresses ("IP Addresses") from the
address space assigned to the GlobalCenter by InterNIC. Client acknowledges
that the IP Addresses are the sole property of GlobalCenter, are assigned to
Client as part of the Service, and are not "portable," as such term is used by
InterNIC. GlobalCenter reserves the right to change the IP Address assignments
at any time; however, GlobalCenter shall use reasonable efforts to avoid any
disruption to Client resulting from such renumbering requirement. GlobalCenter
will give Client reasonable notice of any such renumbering. Client agrees that
it will have no right to IP Addresses upon termination of this Agreement, and
that any renumbering required of Client after termination shall be the sole
responsibility of Client.

3.      SOFTWARE LICENSE AND RIGHTS

3.1.    License.  During the term of the applicable Service Order,
GlobalCenter grants Client a non-transferable, nonexclusive license to use the
Software in object code form only, solely on the Hardware in conjunction with
the Services.

3.2.    Proprietary Rights.  This Agreement transfers to Client neither title
nor any proprietary or intellectual property rights to the Software, Hardware,
documentation, or any copyrights, patents, or trademarks, embodied or used in
connection therewith, except for the rights expressly granted herein.

3.3.    License Restrictions.  Client agrees that it will not itself, or
through any parent, subsidiary, affiliate, agent or other third party.

3.4.1.  copy the Software except as expressly allowed under this Agreement. In
the event Client makes any copies of the Software, Client shall reproduce all
proprietary notices of GlobalCenter on any such copies;

3.4.2.  reverse engineer; decompile, disassemble, or otherwise attempt to
derive source code from the Software;

3.4.3.  sell, lease, license or sublicense the Software or the documentation;

3.4.4.  write or develop any derivative software or any other software program
based upon the Software or any Confidential Information (as described below);
or

3.4.5.  use the Software to provide processing services to third parties, or
otherwise use the Software on a service bureau basis.

4.      HARDWARE TERMS AND CONDITIONS

4.1.    Installation.  GlobalCenter will use commercially reasonable efforts
to install the Hardware as the Hardware is shipped to GlobalCenter. At
Client's request, GlobalCenter will work with the Client on an installation
plan to define installation time frame and requirements.

4.2.    Purchase and Title of Hardware.  If so indicated on the Service Order,
Client shall purchase the Hardware and deliver, at Client's expense, the
Hardware to the Space. Client agrees that the Hardware shall reside at the
Space during the term of this Agreement.

4.3.    Lease of Hardware.  If so indicated on the Service Order, Client shall
lease the Hardware, and GlobalCenter shall obtain and deliver to the Space the

                                                                               1
<PAGE>

             GLOBALCENTER Master Service Agreement No. OWP 00001
================================================================================

Hardware.  In the event Client leases the Hardware, the following terms and
conditions shall apply. The Hardware is and shall remain the property of
GlobalCenter. Client shall not have taken, or attempt to take, any right,
title or interest therein or permit any third party to take any interest
therein. Client will not transfer, sell, assign, sublicense, pledge, or
otherwise dispose of, encumber or suffer a lien or encumbrance upon or against
the Hardware or any interest in the Hardware. Client will use the Hardware
only at the Space. Client will not move the Hardware from that facility
without GlobalCenter's prior written permission. Client shall be responsible
for any damage to the Hardware. Client will use the Hardware only for the
purpose of exercising its rights under this Agreement.

4.4.    Rent to Own.  If so indicated on the Service Order, Client shall lease
the Hardware on a "rent to own" plan. In such event, all of the terms and
conditions in Section 4.3 shall apply, and the following terms and conditions
shall also apply. At the end of the term of the Service Order, providing
Client is not in breach of this Agreement, Client shall have the option to
purchase the Hardware. The purchase price shall be as indicated on the Service
Order. Upon payment by Client of the purchase price, title in the Hardware
shall pass to Client at the Space. Unless the Service Order is extended by
mutual agreement, Client shall immediately delete, or shall allow GlobalCenter
to delete, all copies of the Software, associated documentation, or any other
materials of GlobalCenter resident on the Hardware.

5.      SPACE

5.1.    License to Occupy.  GlobalCenter grants to Client a non-exclusive
license to occupy the Space. Client acknowledges that it has been granted only
a license to occupy the Space and that it has not been granted any real
property interests in the Space. In the event, however, that this arrangement
shall be construed by the owner of the building in which the Space is situated
to be such a grant and if the landlord of the building asserts such a grant to
be a violation of the lease under which GlobalCenter occupies its premises,
GlobalCenter agrees to cooperate with Client in obtaining the approvals Client
may need to obtain from the landlord.

5.2.    Material and Changes.  Client shall not make any construction changes
or material alterations to the interior or exterior portions of the Space,
including any cabling or power supplies for the Hardware, without obtaining
GlobalCenter's prior written approval for Client to have the work performed.
Alternatively, Client may request GlobalCenter to perform the work.
GlobalCenter reserves the right to perform and manage any construction or
alterations within the Space areas at rates to be negotiated between the
Parties hereto. Client agrees not to erect any signs or devices to the
exterior portion of the Space without submitting the request to GlobalCenter
and obtaining GlobalCenter's advance written approval.

5.3.    Damage.  Client agrees to reimburse GlobalCenter for all reasonable
repair or restoration costs associated with damage or destruction caused by
Client's personnel, Client's agents, Client's suppliers/contractors, or
Client's visitors during the term or as a consequence of Client's removal of
the Hardware or property installed in the Space.

5.4.    Insurance. Unless otherwise agreed, Client agrees to maintain, at
Client's expense, (i) Comprehensive General Liability Insurance in an amount
not less than One Million Dollars ($1,000,000) per occurrence for bodily injury
or property damage, (ii) Employer's Liability in an amount not less than Five
Hundred Thousand Dollars ($500,000) per occurrence, and (iii) Worker's
Compensation in an amount not less than that prescribed by statutory limits.
Prior to taking occupancy of the Collocation Space, Client shall furnish
GlobalCenter with certificates of insurance which evidence the minimum levels
of insurance set forth herein. Client shall also maintain insurance covering
Hardware or property owned or leased by Client against loss or physical
damage.

5.5     Regulations.  Client shall comply with and not violate all of
GlobalCenter's safety, health and operational rules and regulations, which may
be amended by GlobalCenter from time to time. Client's failure to comply with
GlobalCenter's rules and regulations shall constitute a material default under
this Agreement. GlobalCenter may, in its sole discretion, limit Client's
access to a reasonable number of authorized Client employees or designees.
Client shall not interfere with any other clients of GlobalCenter, or such
other clients' use of the space.

5.6.    Disclaimer.  GlobalCenter does not make any representation or warranty
whatsoever as to the fitness of the Space for Client's use. Client hereby
assumes any and all risks associated with Client, its agents or employees' use
of the Space and shall indemnify, defend and hold harmless GlobalCenter from
any and all claims, liabilities, judgments, causes of action, damages, costs,
and expenses (including reasonable attorneys' and experts' fees), caused by or
arising in connection with such use.

6.      SERVICE INTERRUPTIONS

6.1.    99% Uptime Guarantee.  In the event of Downtime (as defined below),
the monthly fee payable for the Services shall be reduced as follows:

        6.1.1.   If the total Downtime in the calendar month is more than
        seven and two-tenths (7.2) hours, but does not exceed fourteen and
        four-tenths (14.4) hours, the monthly fee for that month shall be
        reduced by one-third (33.3%);

        6.1.2.   If the total Downtime in the calender month is more than
        fourteen and four-tenths (14.4) hours, but does not exceed twenty-one
        and six tenths (21.6) horus, the monthly fee for that month shall be
        reduced by two-thirds (66.6%); and

                                                                               2
<PAGE>

        6.1.3.  If the total Downtime in the calendar month is more than twenty-
        one and six-tenths (21.6) hours, the monthly fee for that month shall be
        waived.

For the purposes of this Section, Downtime shall mean any interruption of one
(1) minute or more in the availability to users of any Web site residing on the
Hardware and made available through the Services, only if such interruption is
due to either (i) failure by GlobalCenter to manage a server anomaly so as to
avoid interruption in Web availability, or (ii) a disruption in the connection
between any such server and the Internet. For purposes of this Section, the
Internet is deemed to consist of services that commence where GlobalCenter
transmits a Client's content to GlobalCenter's  carrier(s) at the GlobalCenter
border router port(s). Such carriers provide GlobalCenter with private and
dedicated bandwidth. GlobalCenter undertakes no obligation for the circuit or

95th Percentile Rule
Every Frontier GlobalCenter direct purchase a guaranteed amount of bandwidth
per month on the Frontier GlobalCenter Internet Backbone.  Bandwidth
fluctuations do occur over time and there may be certain periods where your
Site will burst over the amount of bandwidth purchased.  Frontier Global clients
are billed for the guaranteed or committed bandwidth each month.  Bandwidth
above that completed amount is determined and billed via Frontier GlobalCenter's
SNMP bandwidth monitoring.  Frontier GlobalCenter will sample (samples equal
data point reflecting bandwidth utilization at that particular instance) your
average bandwidth utilization every 30 minutes and store those samples for a
period of one month.

At one end of the month, all data samples are sorted from highest to lowest and
the top 3% are discarded.  The highest remaining data sample will the be
referred to as the "95th Percentile" number.  This member will then used as the
basis in conducting the bandwidth rate for that particular month over the
guaranteed or committed bandwidth rate.
