                            (2004-2005 AND 2005-2007)

      THIS ADDENDUM #1 TO LICENSING AND DISTRIBUTION AGREEMENTS(this "Addendum")

Development Agreement (Manufacturing Rights)(2005-2007), dated as of March 29,

particularly described in each of the Agreements.

      B.    Riverdeep currently distributes some or all of the Products into the
Channel through certain agreements with COKeM and has requested Distributor's
consent to maintain such agreements in effect through the expiration of their
terms, or earlier termination. Distributor is willing to agree to such
arrangements upon the terms and subject to the conditions set forth herein.

      NOW, THEREFORE, in consideration of the mutual covenants and agreements

2.    COKeM AGREEMENTS; SELL-OFF AND INVENTORY PURCHASE.

      2.1   Riverdeep hereby represents and warrants to Distributor that (i)
attached hereto as Exhibit A is a true and correct schedule of all of the
agreements between Riverdeep and COKeM in effect as of the date hereof other
than the agreement with COKeM set forth on Exhibit C of Agreement One (such
agreements being collectively referred to as the "COKeM Agreements), true,
correct, and complete copies of which have heretofore been provided to
Distributor; (ii) there are no extensions, supplements, amendments or other
modifications ("Modifications") to any of the COKeM Agreements; and, (iii)
notwithstanding the provisions of each of the COKeM Agreements, COKeM currently
has no ability to manufacture any of the COKeM Products.

      2.2   From and after the date hereof until the expiration or sooner
termination of all of the COKeM Agreements, Riverdeep shall (i) perform all of
Riverdeep's obligations under the COKeM Agreements (except to the extent
Distributor is responsible therefor hereunder) and shall not enter into or
otherwise agree to any Modifications thereto without Distributor's prior written
consent, to be granted or denied in Distributor's sole discretion; (ii) not
waive any of COKeM's obligations, grant any additional rights, or give any
consents or approvals to COKeM, under any of the COKeM Agreements without
Distributor's prior written consent, to be granted or denied in Distributor's
sole discretion; and, (iii) provide, supply, and fulfill all COKeM Products to
COKeM solely in accordance with the terms of this Addendum.

      2.3   Riverdeep hereby appoints Distributor its exclusive inventory
manager to manage, fulfill, and process all purchase orders for COKeM Products
that Riverdeep receives from COKeM from and after April 13, 2004, until the
expiration or sooner termination of all of the COKeM Agreements. To that end, in
respect of the COKeM Agreements, Distributor shall fill purchase orders received
by Riverdeep from COKeM; assist in inventory management; subject to the
reimbursement herein, arrange for the manufacture of all finished goods of COKeM
Products so ordered; and process and ship such units to such locations directed
by Riverdeep. Unless otherwise agreed to between the parties, Riverdeep shall
remain the point of contact with COKeM. In addition, Riverdeep shall remain
directly responsible and solely liable (i) for collecting all amounts due under
the COKeM Agreements and shall remain entitled to collect all amounts in
connection therewith, and (ii) for all amounts due under, and for all
liabilities associated with, the COKeM Products or COKeM Agreements. Riverdeep
shall cooperate with Distributor in order to enable Distributor to carry out its
obligations hereunder.

      2.4   No later than 30 days after each month, Riverdeep shall reimburse
Distributor, or Distributor in its sole discretion may deduct from amounts
otherwise payable by Distributor to Riverdeep, all direct costs, fees, charges,
and expenses incurred or owed by Distributor to manufacture, process, fulfill,
handle, and ship all COKeM Products during such period in accordance with
Riverdeep's obligations under the COKeM Agreements (including, without
limitation, cost of goods, shipping, handling, and insurance to the extent
applicable). In addition, Riverdeep shall pay Distributor, or Distributor in its
sole discretion may deduct from amounts otherwise payable by Distributor to
Riverdeep, each month, concurrently with the foregoing amounts, a nonrefundable,
irrevocable management fee equal to 30% of the aggregate amount of such monthly
direct costs.

      2.5   Distributor acknowledges that (i) Distributor's exclusivity under
the Agreements to the accounts serviced by COKeM under the COKeM Agreements
shall be limited to such extent; and (ii) Riverdeep shall not be deemed to be in
breach of that representation and warranty stated at 7.1(iv) of the Agreements
by reason of COKeM's rights under the COKeM Agreements so long as Riverdeep
complies with the terms of this Addendum. However, immediately upon the
expiration of the terms of the COKeM Agreements, or upon their earlier
termination for whatever reason, the exclusivity granted to Encore with respect
to those retail accounts serviced by COKeM under the COKeM Agreements shall
immediately revert back to Encore as was originally contemplated under the
Agreements, and that certain representation and warranty stated at 7.1(iv) of
the Agreements shall apply to Riverdeep without exception.

      2.6   Subject to the terms and conditions of this Addendum, Distributor
hereby agrees to purchase from Riverdeep the COKeM Inventory; provided however,
that in no event shall Distributor be obligated to purchase more than ten weeks
of inventory of any SKU of any Product of such COKeM Inventory; and provided
further, that Riverdeep shall have ceased accepting purchase orders from COKeM
as of December 31, 2004. The purchase price for the COKeM Inventory shall be
that amount that COKeM originally paid Riverdeep for such inventory and shall be
payable within 60 days after each month in which any such inventory is sold by
Distributor.

      2.7   Notwithstanding anything to the contrary in the Agreements, and
without limiting any other credits, offsets, or reimbursements available to
Distributor under the Agreements:

            2.7.1 Riverdeep shall not be entitled to earn Royalties under the
      Agreements (i) on COKeM Products for which Distributor acts as inventory
      manager pursuant to Section 2.2 above, or (ii) on the COKeM Inventory.
      Distributor shall maintain and provide to Riverdeep such sales information
      and other data necessary to confirm sales of the COKeM Inventory by
      Distributor and the royalty treatment of such inventory as provided
      herein.

            2.7.2 Distributor shall be entitled to a credit on a monthly basis
      against the Guaranteed Royalties under Agreement One (or, if the entire
      Guaranteed Royalty under Agreement One has been paid, then the Guaranteed
      Royalties under Agreement Two) in an amount equal to that which Riverdeep
      would have earned in Royalties under Agreement One (without regard to
      Section 2.3.1 above) if each of the following categories of Products had
      been distributed by Distributor in accordance with the terms of Agreement
      One: (i) those COKeM Products sold by COKeM from and after the date upon
      which the COKeM Termination Event (as defined below) occurs, and (ii) the
      COKeM Inventory sold by Distributor. Riverdeep shall provide such sales
      data to Distributor to enable Distributor to calculate the amount of such
      credit.

            2.7.3 In addition, Distributor shall be entitled to a credit on a
      monthly basis against the Guaranteed Royalties under Agreement One (or, if
      the entire Guaranteed Royalty under Agreement One has been paid, then the
      Guaranteed Royalties under Agreement Two) in an amount equal to (i) the
      amount by which the purchase price paid by Distributor for the COKeM
      Inventory under Section 2.2 above, exceeds (ii) the wholesale price for
      which Distributor is able to sell the COKeM Inventory.

3.    MODIFICATIONS TO THE AGREEMENTS.

      3.1   The first sentence of Section 4.2.1 of Agreement One is hereby
amended in its entirety to read as follows:

            "Distributor shall pay a guaranteed, irrevocable, non-refundable
            payment (recouped against royalties as hereinafter provided) for the
            Sales Year (as the same may be increased in accordance with this
            Section 4.2.1 below, the "Guaranteed Royalty") in the amount of
            $9,000,000. In the event that Riverdeep is able to obtain for Encore
            during the first Sales Year (i) all of the rights granted to COKeM
            under all of the COKeM Agreements, and (ii) a mutual termination and
            release, in form and substance satisfactory to Distributor in its
            sole discretion, pursuant to which COKeM shall have relinquished all
            its rights under the COKeM Agreements to distribute the Products
            into the Channel and shall have released all claims related to the
            distribution of Products in the Channel by Distributor or otherwise
            arising under the COKeM Agreements (the satisfaction of the
            aforementioned conditions being referred to herein as the "COKeM
            Termination Event"), the Guaranteed Royalty shall be increased by
            $2,000,000, such amount to be pro-rated based on the remaining
            portion of the Sales Year. (Thus, for example, if the COKeM
            Termination Event occurs at the end of 6 months after the
            Commencement Date, then the Guaranteed Royalty shall be increased by
            $1,000,000.)"

      3.2   Section 9.1 of Agreement Two is hereby amended in its entirety to
read as follows:

            "This Agreement shall commence on the Commencement Date and shall
            continue in effect for a period of five (5) years from the
            Commencement Date (as the same may be extended hereunder, the
            "Term"). The Term shall be extended for any extended recoupment
            periods under Section 4 hereof. Each of the first, second, third,
            fourth, and fifth Sales Year is conditioned on the payment of the
            applicable Guaranteed Royalty for the preceding Sales Year."

      3.3   Section 4.2.1(ii) of Agreement Two is hereby amended in its entirety
to read as follows:

            "In respect of each of the second, third, fourth, and fifth Sales
            Years, the Guaranteed Royalty shall be 80% of the actual Royalties
            earned by Riverdeep from sales of the Products during the preceding
            Sales Year; provided however, that such Guaranteed Royalty shall be
            prorated in respect of any portion of a Sales Year hereunder;
            provided further, that no Guaranteed Royalty shall be payable under
            any circumstances for any period of time that the Term is extended
            solely in order to accommodate any extended recoupment periods under
            Section 4.2.2. For clarity, any adjustments or credits that could
            accrue in any Sales Year under Agreement Two prior to this Addendum
            shall accrue in the same manner and be applied to the same extent
            during the third, fourth, and fifth Sales Years created by this
            Addendum."

                                       4

      3.4   All references in each Agreement to the term "Agreement" shall
hereafter mean such Agreement as the same has been amended in accordance with
the terms hereof.

4.    REAFFIRMATION OF REPRESENTATIONS AND WARRANTIES. Both parties reaffirm the
representations and warranties set forth in the Agreements, as amended by the
terms hereof.

5.    CONFLICT. In the event of any conflict between the terms of the Agreements
and the terms of this Addendum, the terms of this Addendum shall prevail.
Otherwise, except as specifically set forth in this Addendum, all the terms and
conditions of the Agreements are hereby ratified and affirmed.

to the subject matter hereof and supersedes all prior understandings, writings,
proposals, representations, or communications, oral or written, of either party
relating to the subject matter of this Addendum. This Addendum may be executed

construed as conferring any rights or benefits to or upon any party not a party
to this Agreement, including, without limitation, COKeM.
