September 7, 2001

Dear Shareholder,

     This is truly an exciting time for Bid.Com International Inc.

     Enclosed with this letter you will find a Notice and Management Information
Circular relating to a Special Meeting of our Shareholders to be held on
Wednesday, October 10, 2001. The purpose of this Meeting is to inform you of an
acquisition which we believe will have a dramatic impact on our Company, and to
seek your approval of this exciting opportunity.

     ADB Systemer ASA, based in Norway, is a leading provider of asset
management and procurement solutions to the Oil and Gas and Public sectors.
Recognized by the Gartner Group as one of the Tier One enterprise asset
management companies in the world, ADB has combined a strong suite of software
products with industry expertise in a manner which has allowed them to earn
business from an impressive list of clients, including BP, AMEC, and
Halliburton.

     In combination with our suite of products, in particular our Dynamic Buyer
sourcing solution, we believe the joint product offering will be a compelling
one for companies in North America and Europe, in particular for Oil and Gas and
Public sector clients. By focusing on these two sectors, we believe the combined
entity will be able to leverage ADB's industry expertise most effectively, while
adding a value-added dimension for the benefit of existing clients.

     This Meeting also presents us the opportunity to address two other issues
which have become pressing in recent times -- our corporate name and our share
price. It is generally acknowledged that with the overall decline of the so-
called "dot-coms" our name has gradually become a liability, particularly in
light of our reduced reliance on pure auction or "bid" activities. Although
dynamic pricing will continue to be a key part of our core technology offering
we now believe that the time is right to change our corporate identity in
concert with the acquisition of ADB. The attached circular proposes a change of
name to ADB Systems International Inc., in order to take advantage of existing
goodwill and to expedite the re-branding process.

     Since the acquisition involves the issuance of shares, we are also
proposing a share consolidation, with the intention of improving our share price
and reducing our public float to more manageable levels.

     We truly believe that this acquisition offers a "one plus one equals three"
opportunity, with substantial sales, technology and infrastructure benefits. We
are looking forward to seeing you on October 10.

Yours truly,

Jeffrey Lymburner
