                              PRELIMINARY STATEMENT

          Reference is made to (a) the Revolving Loan Credit Agreement dated as

from time to time, the "REVOLVING LOAN CREDIT AGREEMENT"), among the Grantor,
Gallarus Media Holdings, Inc., a Delaware corporation ("HOLDINGS"), the lenders
from time to time party thereto (the "REVOLVING LENDERS") and Credit Suisse, as
administrative agent, (b) the Term Loan Credit Agreement dated as of November
30, 2005 (as amended, restated, supplemented or otherwise modified from time to
time, the "TERM LOAN CREDIT AGREEMENT" and, together with the Revolving Loan
Credit Agreement, the "CREDIT AGREEMENTS"), among the Grantor, Holdings, the
lenders from time to time party thereto (the "TERM LENDERS" and, together with
the Revolving Lenders, the "LENDERS") and Credit Suisse, as administrative
agent, and (c) the Guarantee, Collateral and Intercreditor Agreement dated as of
November 30, 2005 (as amended, restated, supplemented or otherwise modified from
time to time, the "GUARANTEE, COLLATERAL AND INTERCREDITOR AGREEMENT"), among
the Grantor, Holdings, the subsidiaries party thereto and Credit Suisse, in its
separate capacities as collateral agent (in such capacity, the "COLLATERAL
AGENT") for the Secured Parties (as defined in the Guarantee, Collateral and
Intercreditor Agreement), and as administrative agent under each of the Credit
Agreements.

          The Revolving Lenders and the Issuing Bank have agreed to extend
credit to the Grantor subject to the terms and conditions set forth in the
Revolving Loan Credit Agreement, and the Term Lenders have agreed to make term
loans to the Grantor subject to the terms and conditions set forth in the Term
Loan Credit Agreement. The obligations of the Lenders and the Issuing Bank to
extend such credit are conditioned upon, among other things, the execution and
delivery of this Agreement.

          Accordingly, in consideration of the premises and mutual covenants
herein contained and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Grantor hereby agrees as
follows:

          SECTION 1. DEFINED TERMS. All capitalized terms used but not otherwise
defined herein have the meanings given to them in the Revolving Loan Credit
Agreement, the Term Loan Credit Agreement or the Guarantee, Collateral and
Intercreditor Agreement, as applicable.

          SECTION 2. GRANT OF SECURITY INTEREST IN TRADEMARK COLLATERAL. The
Grantor hereby grants to the Collateral Agent (and its successors and assigns),
for the ratable benefit of the Secured Parties, a continuing security interest

                                                                               2

in all of the Grantor's right, title and interest in, to and under the
following, whether presently existing or hereafter created or acquired
(collectively, the "TRADEMARK COLLATERAL"):

          (a) all of its Trademarks and Trademark Licenses to which it is a
     party, including, without limitation, those referred to on Schedule I
     hereto;

          (b) all reissues, continuations or extensions of the foregoing;

          (c) all products and proceeds of the foregoing, including, without
     limitation, any claim by the Grantor against third parties for past,
     present or future infringement or dilution of any Trademark or any
     Trademark licensed under any Trademark License.

     Notwithstanding the foregoing, the Trademark Collateral shall not include
any rights in any Trademarks or Trademark Licenses or other interests of the
Grantor that would be rendered invalid or unenforceable under applicable law by
the grant of a security interest, for so long as such reason for invalidity or
unenforceability under applicable law exists.

          SECTION 3. GUARANTEE AND COLLATERAL AGREEMENT. The security interests
granted pursuant to this Agreement are granted in conjunction with the security
interests granted to the Collateral Agent (and its successors and assigns), for
the ratable benefit of the Secured Parties, pursuant to the Guarantee,
Collateral and Intercreditor Agreement. The Grantor hereby acknowledges and
affirms that the rights and remedies of the Collateral Agent with respect to the
security interest in the Trademark Collateral made and granted hereby are more
fully set forth in the Guarantee, Collateral and Intercreditor Agreement, the
terms and provisions of which are incorporated by reference herein as if fully
set forth herein, and in the event of any conflict between the terms and/or
conditions of this Agreement and the terms of the Guarantee, Collateral and
Intercreditor Agreement, the terms and/or conditions of the Guarantee,
Collateral and Intercreditor Agreement shall control.

          SECTION 4. COUNTERPARTS. This Agreement may be executed in any number
of counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
instrument.
