    Re: Registration Statement and Conversion Price

Dear Alan:

    This letter will confirm our agreement that:

    1.  Network Commerce Inc. ("NWKC") has agreed to file, within 5 days of the
date hereof, a Section 462(b) Registration Statement for the purpose of
increasing the number of shares of NWKC common stock previously registered by
NWKC on November 22, 2000, on Form S-3 for public resale by Capital Ventures
International ("CVI") by 20%, from 11,250,000 shares to 13,500,000 shares. Of
the 13,500,000 shares so registered, 12,000,000 shares represent the number of
shares issuable to CVI upon conversion of the $20 million principal amount of
Convertible Notes, and all accrued interest thereon from the date of issuance
through November 22, 2000, purchased by CVI from NWKC pursuant to the Securities
Purchase Agreement dated September 28, 2000.

    2.  NWKC shall have no further obligation pursuant to Section 2(c) of the
Registration Rights Agreement to register additional shares of its common stock
for resale by CVI above the 13,500,000 shares referenced in Paragraph 1 above,
unless an adjustment to the Conversion Price of the Notes shall occur pursuant
to Article VII of the Notes, and shall not be liable to CVI for penalties under
Section 2(c) of the Registration Rights Agreement resulting solely from its
failure to register 100% of the Registrable Securities (as such term is defined
in the Registration Rights Agreement); provided, however, that all other
obligations, set froth in the Securities Purchase Agreement, the Registration
Rights Agreement, the Notes and the Warrants, of NWKC with respect to the
Registration Statement shall remain in full force and effect.

    3.  The Conversion Price of the $20,000,000 principal amount of Convertible
Notes purchased by CVI from NWKC pursuant to the Securities Purchase Agreement
is reduced from $7.50 to $1.682, subject to further adjustment as provided in
the Notes.
