To Brokers, Dealers, Commercial Banks,
   Trust Companies and Other Nominees:

   Enclosed for your consideration is an Offer to Purchase (the "Offer to
Purchase") and a form of Letter of Transmittal (the "Letter of Transmittal"),
relating to the offer by Internet Capital Group, Inc. ("Purchaser"), a Delaware
corporation, to purchase for cash, upon the terms and subject to the conditions
set forth in the Offer to Purchase and Letter of Transmittal, up to
$200,000,000 aggregate principal amount of outstanding 51/2% Convertible
Subordinated Notes due 2004 of Purchaser (the "Notes") at a price not greater
than $250 nor less than $200, per $1,000 principal amount, plus accrued and
unpaid interest thereon to, but not including, the date of purchase, at a price
determined by the "Modified Dutch Auction" procedure described below.

   The maximum aggregate principal amount listed above for the Notes is
referred to as the "Offer Amount" for the Notes. The Offer Amount is less than
36% of the aggregate outstanding principal amount of the Notes.

   Under the "Modified Dutch Auction" procedure, Purchaser will accept Notes
validly tendered (and not withdrawn) in the Offer in the order of the lowest to
the highest tender prices specified or deemed to have been specified by
tendering holders within the price range for the Notes subject to the Offer,
and will select the single lowest price so specified (the "Purchase Price")
that will enable Purchaser to purchase the Offer Amount (or, if less than the
Offer Amount are validly tendered (and not withdrawn), all Notes so tendered).
Purchaser will pay the same Purchase Price for all Notes validly tendered at or
below the Purchase Price (and not withdrawn).

   In the event that the amount of Notes validly tendered (and not withdrawn)
on or prior to the Expiration Date (as defined below) at or below the Purchase
Price exceeds the Offer Amount then Purchaser will accept for payment of such
Notes that are validly tendered (and not withdrawn) at or below the Purchase
Price on a pro rata basis from among such tendered Notes. In all cases,
Purchaser will make appropriate adjustments to avoid purchases of Notes in a
principal amount (or principal amount at maturity, as applicable) other than an
integral multiple of $1,000.

   Capitalized terms used and not defined herein shall have the meanings
ascribed to them in the Offer to Purchase.
