              -----------------------------------------------------------

Dear Purchasers:

         Pursuant to that certain Securities Purchase Agreement by and among
CDKNet.com, Inc. (the "Company"), Bushido Capital Master Fund, L.P., Gamma
Opportunities Capital Partners, LP Class A and Gamma Opportunities Capital
Partners, LP Class C (collectively, the "Purchasers"), dated December 28, 2005
(the "Purchase Agreement"), and the related Transaction Documents (as defined in
the Purchase Agreement), the Purchasers were issued certain of the Company's 6%
Senior Secured Debentures ("Debentures") and Common Stock Purchase Warrants
("Warrants"). Pursuant to the Registration Rights Agreement, as amended, the
Purchasers received registration rights on the shares underlying the Debentures
and Warrants, including a specified Filing Date and Effectiveness Date (as
defined in the Registration Rights Agreement) for the registration statement. In
connection with the Third Additional Issuance Agreement, dated March 31, 2006,
between the Company and Cargo Holdings LLC, and other developments of the
Company, the Company and the Purchasers are entering into this letter agreement,
dated the date hereof (the "Letter Agreement"). Capitalized terms used and not
otherwise defined herein that are defined in the Purchase Agreement shall have
the meanings given such terms in the Purchase Agreement.

         For good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the Purchasers hereby agree to the following
extension, waiver and amendment in connection with the Transaction Documents:

         (a)  Extension and Waiver. Pursuant to the Registration Rights
              Agreement, as amended, the Company agreed to a Filing Date of
              March 28, 2006 and an Effectiveness Date of June 11, 2006. The
              Purchasers hereby agree (i) to extend the Filing Date to October
              15, 2006 and the Effectiveness Date to December 14, 2006 in the
              Registration Rights Agreement and (ii) to waive any past or
              present default or liquidated damages, as set forth in the
              Debentures and the Registration Rights Agreement, arising from the
              failure by the Company to comply with the Filing Date of March 28,
              2006.

         (b)  Amendment. The Purchasers hereby agree to amend the definition of
              "Exempt Issuance" set forth in Section 1.1 of the Purchase
              Agreement to add the following clause (f) immediately following
              the word "securities" in the last sentence:


                                        1


              "OR (F) THE ISSUANCE OF WARRANTS TO EMERGING MARKETS
              CONSULTING LLC PURSUANT TO A CONSULTING AGREEMENT, PROVIDED
              THAT THE EXERCISE PRICE OF SUCH WARRANTS EQUALS OR EXCEEDS
              $0.85 PER SHARE AND SUCH ISSUANCE OF WARRANTS SHALL NOT EXCEED
              180,000 IN ANY 3 CALENDAR MONTH PERIOD".

         The Company hereby agrees to reimburse the Purchasers for all expenses,
including attorneys' fees, in connection with the preparation and execution of
this Letter Agreement and the preparation of the Third Additional Issuance
Agreement.
