8.       ASSIGNMENT AND SUBLICENSES

         8.1 Assignment Agreements. By the Patent Assignment, the Copyright and
Technology Assignment and the Trademark and Service Mark Assignment, on the
Closing, Holdco, on behalf of itself and each of its Subsidiaries, shall assign
to the Company any and all rights, title and interest in, to and under any
Existing TWIC Broadband Group Patents, TWIC Broadband Group Content, TWIC
Broadband Group Trademarks, TWIC Broadband Group Software and TWIC Broadband
Group Proprietary Information.

         8.2 Assignment of TWIC Broadband IP Licenses. Holdco, on behalf of
itself and each of its Subsidiaries, does hereby assign, convey, transfer and
deliver to the

                                       7
<PAGE>

Company effectively immediately following the Closing, all of Holdco's and
each of its Subsidiaries' entire right, title and interest, to, in and under all
TWIC Broadband IP Licenses, in accordance with the terms of such licenses and
only to the extent Holdco has the right to do so (subject to its obligations in
Section 16.3.1), together with any and all rights and licenses granted to the
Company pursuant to this Agreement. Immediately after the assignment to the
Company set forth in this Section 8.2, Holdco and the other TWIC Non-Broadband
Members shall no longer retain any rights or licenses granted to the Company
pursuant to this Agreement.

         8.3 Failure of Assignment. In the event that a particular TWIC
Broadband IP License cannot be assigned by Holdco to the Company after
assistance has been fully rendered in accordance with the obligations set forth
in Section 16.3.1, then, with respect to such a TWIC Broadband IP License that
is

                  8.3.1 an Outbound TWIC Non-Broadband IP License, Holdco hereby
irrevocably appoints the Company as Holdco's exclusive agent for administering
such Outbound TWIC Broadband IP License and hereby irrevocably assigns to the
Company any and all right, title and interest in and to all royalties and other
payments to be paid to Holdco pursuant to such Outbound TWIC Broadband IP
License. Holdco shall, on behalf of itself and each of its Subsidiaries, at any
time without charge to the Company, sign all papers, take all rightful oaths,
and do all acts which the Company believes to be necessary, desirable or
convenient to effect such appointment and assignment, including sending such
letters as the Company may request directing licensees under such Outbound TWIC
Non-Broadband IP Licenses to make payments to the Company.

                  8.3.2 an Inbound TWIC Broadband IP License, Holdco shall, to
the fullest extent permitted by such Inbound TWIC Broadband IP License, exercise
its rights for the maximum benefit and protection of the Company, and Holdco, to
the fullest extent permitted without jeopardizing Holdco's license rights under
such Inbound TWIC Broadband IP License, hereby irrevocably appoints the Company
as an agent for Holdco under such Inbound TWIC Broadband IP License with full
authority to act on behalf of Holdco to ensure that the TWIC Broadband Group
enjoys the maximum benefit and protection of such Inbound TWIC Broadband IP
License. Holdco shall, on behalf of itself and each of its Subsidiaries, at any
time without charge to the Company, sign all papers, take all rightful oaths,
and do all acts which the Company believes to be necessary, desirable or
convenient to effect such appointment, including sending such letters as the
Company may request advising licensors of such appointment.

         8.4 Order of Precedence. In the event of any inconsistency between the
terms and conditions of this Agreement and those of the Patent Assignment, the
Copyright and Technology Assignment, or the Trademark and the Service Mark
Assignment, the order of priority shall be first the Patent Assignment, the
Copyright and Technology Assignment, or the Trademark and Service Mark
Assignment, as applicable, and second this Agreement.

9.       ASSIGNMENT

                                       8
<PAGE>

         9.1 Neither Party shall assign its rights or obligations under this
Agreement without the prior written consent of the other Party, unless such
assignment is to a Person who is or becomes an Affiliate of such Party. This
Agreement shall be binding upon and inure to the benefit of and be enforceable
by the successors, legal representatives and permitted assigns of each of the
Parties.

         9.2 Subject to the terms and conditions of this Agreement and the
Ancillary Agreements, as applicable, the Company shall have the right to assign,
transfer, convey, license or use in any manner, any intellectual property,
including Software, Proprietary Information, Patents, Content and Trademarks,
owned by the Company, whether as a result of allocations, assignments or
transfers set forth in or contemplated by this Agreement, the Ancillary
Agreements or otherwise.

10.      INFRINGEMENT

                  The Company and Holdco agree to reasonably cooperate with each
other in the protection and enforcement of the intellectual property licensed to
the other Party pursuant to this Agreement. Licensor may, in its sole
discretion, commence or prosecute and effect the disposition of any claims or
suits relative to the infringement, misappropriation and/or unlawful use of the
licensed intellectual property in its own name and may, with Licensee's
permission, such permission not to be unreasonably withheld or delayed, join
Licensee as a party in the prosecution of such claims or suits. Licensee agrees
to reasonably cooperate with Licensor in connection with any such claims or
suits and undertakes to furnish reasonable assistance to Licensor in the conduct
of all proceedings in regard thereto. Both Parties shall promptly notify the
other party in writing of any infringement, misappropriation or illegal uses by
others of the licensed intellectual property.

11.      NO WARRANTIES OR REPRESENTATIONS

                  ALL SOFTWARE, PROPRIETARY INFORMATION, PATENTS AND CONTENT
COVERED UNDER THIS AGREEMENT ARE FURNISHED "AS IS," WITHOUT ANY SUPPORT,
ASSISTANCE, MAINTENANCE OR WARRANTIES OF ANY KIND, WHATSOEVER.

                  EACH GROUP ASSUMES TOTAL RESPONSIBILITY AND RISK FOR ITS USE
OF ANY SOFTWARE, PATENTS, PROPRIETARY INFORMATION OR CONTENT COVERED BY THIS
AGREEMENT. NEITHER GROUP MAKES, AND EACH GROUP EXPRESSLY DISCLAIMS, ANY EXPRESS
OR IMPLIED WARRANTIES OF ANY KIND WHATSOEVER, INCLUDING, BUT NOT LIMITED TO,
IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE,
WARRANTIES OF TITLE OR NON-INFRINGEMENT, OR ANY WARRANTY THAT SUCH SOFTWARE,
PATENTS, PROPRIETARY INFORMATION OR CONTENT IS "ERROR FREE."

12.      GOVERNING LAW; IP CLAIMS

         12.1 Choice of Law. This Agreement shall be governed by, and construed
and enforced in accordance with, the laws of the State of New York without
regard to its principles of conflicts of law. Except as otherwise provided
herein, the Company and Holdco hereby irrevocably submit to the exclusive
jurisdiction of the United States District Court for the Southern District of
New York, or absent subject matter jurisdiction in that court, the state courts
of the State of New York located in New York County for all actions, suits or
proceedings arising in connection with this Agreement.

         12.2 Intellectual Property Rights. Notwithstanding any provision in
this Agreement, the TWIC Contribution Agreement or any Ancillary Agreement, in
no event shall any claims, disputes or controversies between the Parties which
potentially concern the validity, enforceability, infringement or
misappropriation of any intellectual property rights, including any rights
protectable under intellectual property law anywhere throughout the world such
as Patent, Copyright, trade secret and Trademark law, be subject to resolution
by arbitration.

         12.3 Equitable Remedies. The Parties recognize that money damages alone
may not be an adequate remedy for any breach or threatened breach of any
obligation hereunder involving intellectual property rights or either Party
exceeding the scope of its license and rights hereunder. The Parties therefore
agree that in addition to any other remedies available hereunder, by law or
otherwise, the non-breaching Party shall be entitled to seek injunctive relief
against any such continued action by the other Parties.

         12.4 Bankruptcy. This Agreement constitutes a license of "intellectual
property" within the meaning of Section 365(n) of the United States Bankruptcy
Code. If Section 365(n) of the United States Bankruptcy Code (or any successor
provision) is applicable, and the trustee or debtor-in-possession has rejected
this Agreement and if the Licensee has elected pursuant to Section 365(n) to
retain its rights hereunder, then upon written request of Licensee, to the
extent Licensee is otherwise entitled hereunder, the trustee or
debtor-in-possession shall provide to Licensee any intellectual property
(including embodiments thereof) held or controlled by the trustee or
debtor-in-possession.

13.      NOTICE

              Unless otherwise provided in this Agreement, all notices,
consents, approvals, waivers and the like made hereunder shall be in written
English addressed as provided below, shall reference this Agreement and shall be
sent by any of the following methods: (a) certified mail, postage-prepaid,
return-receipt requested, (b) a delivery service which requires proof of
delivery signed by the recipient or (c) properly-transmitted facsimile followed
by written confirmation in accordance with methods (a), (b) or first-class U.S.
mail. The date of notice shall be deemed to be the date it was received (in the
case of method (c) above, the date of notice shall be deemed to be the date that
the facsimile copy is received). A Party may change its address for notice by
written notice delivered in accordance with this Section 13.

<PAGE>

         16.2 No Enforcement Against Third-Party. Notwithstanding any provision
of this Agreement or the Ancillary Agreements, in no event shall any member of
any Group be required to enforce or otherwise assert against any Person any
intellectual property rights.

         16.3 Further Assurances. Each Party covenants to execute upon request
any further documents reasonably necessary to effect the express terms and
conditions of this Agreement, including such documents as are reasonably
necessary to vest title in intellectual property rights as provided in this
Agreement. All expenses incurred in connection with such actions shall be paid
in accordance with Section 15.

                  16.3.1 Assistance with Assignment. Holdco shall, at any time
without charge to the Company, sign all papers, take all rightful oaths, and do
all acts which the Company believes are necessary, desirable or convenient to
assign, convey, transfer and deliver to the Company any licenses to be assigned
pursuant to Section 8.2, and to record such assignments with the appropriate
Governmental Authorities, including without limitation, using reasonable efforts
to seek consent of any party to any such license for the assignment of the same
to the Company. It is understood and agreed that Holdco shall not be required to
undertake extraordinary or unreasonable measures to obtain any necessary
consent, including making any expenditures or accepting any material changes in
the terms of any license agreement for which consent is sought.

         16.4 Rules of Construction. As used in this Agreement, (i) neutral
pronouns and any derivations thereof shall be deemed to include the feminine and
masculine and all terms used in the singular shall be deemed to include the
plural and vice versa, as the context may require; (ii) the words "hereof,"
"herein," "hereunder" and other words of similar import refer to this Agreement
as a whole, including all exhibits and schedules as the same may be amended or
supplemented from time to time, and not to any subdivision of this Agreement;
(iii) the word "including" or any variation thereof means "including, without
limitation" and shall not be construed to limit any general statement that it
follows to the specific or similar items or matters immediately following it;
(iv) descriptive headings and titles used in this Agreement are inserted for
convenience of reference only and do not constitute a part of and shall not be
utilized in interpreting this Agreement; (v) the words "Party" and "Parties"
refer, respectively, to each or both parties to this Agreement (vi) reference to
a work of authorship or information as being created or developed by a Party
means that the work of authorship or information is created or developed by
employees of that Party or by such other individuals, such as contractors, who
have a duty to assign ownership in such work of authorship or information to
such Party. This Agreement shall be fairly interpreted in accordance with its
terms and without any strict construction in favor of or against either Party.

         16.5 Amendments. This Agreement may not be amended, changed,
supplemented, waived or otherwise modified except by an instrument in writing
signed by the Parties.

         16.6 No Waiver. The failure of either Party to exercise any right,
power or remedy provided under this Agreement or otherwise available in respect
hereof at law or in

                                       13
<PAGE>

equity, or to insist upon compliance by the other Party with its obligations
hereunder, and any custom or practice of the Parties at variance with the terms
hereof, shall not constitute a waiver by such Party of its right to exercise any
such or other right, power or remedy or to demand such compliance.

         16.7 Third Party Beneficiaries. The provisions of this Agreement and
each Ancillary Agreement are solely for the benefit of the Parties and are not
intended to confer upon any Person except the Parties any rights or remedies
hereunder and there are no third party beneficiaries of this Agreement or any
Ancillary Agreement and neither this Agreement nor any Ancillary Agreement shall
provide any third person with any remedy, claim, liability, reimbursement, claim
of action or other right in excess of those existing without reference to this
Agreement or any Ancillary Agreement. No Party hereto shall have any right,
remedy or claim with respect to any provision of this Agreement or any Ancillary
Agreement to the extent such provision relates solely to the other Party hereto.
No Party shall be required to deliver any notice under this Agreement or under
any Ancillary Agreement to any other Party with respect to any matter in which
such other Party has no right, remedy or claim.

         16.8 Force Majeure. No Party shall be deemed in default of this
Agreement or any Ancillary Agreement during the period of extension referred to
in the next sentence to the extent that any delay or failure in the performance
of its obligations under this Agreement or any Ancillary Agreement results from
any cause beyond its reasonable control and without its fault or negligence,
such as acts of God, criminal or terrorist acts, acts of civil or military
authority, embargoes, epidemics, war, riots, insurrections, fires, explosions,
earthquakes, floods, unusually severe weather conditions, labor problems or
unavailability of parts, or, in the case of computer systems, any failure in
electrical or air conditioning equipment. In the event of any such excused
delay, the time for performance shall be extended for a period equal to the time
lost by reason of the delay, but in no event shall such period of extension
exceed 45 days.

         16.9 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute one instrument. Each counterpart may consist of a
number of copies each signed by less than all, but together signed by all, the
Parties.

         16.10 Severability. The provisions of this Agreement are severable, and
in the event that any one or more provisions, or any portion thereof, are deemed
illegal or unenforceable, the remaining provisions or portions thereof, as the
case may be, shall remain in full force and effect unless the deletion of such
provision or portion thereof shall cause this Agreement to become materially
adverse to either Party, in which event the Parties shall use commercially
reasonable efforts to arrive at an accommodation that best preserves for the
Parties the benefits and obligations of the offending provision or portion
thereof.

         16.11 Entire Agreement. This Agreement together with the Ancillary
Agreements set forth the entire agreement and understanding between the Parties
as to the subject matter hereof and thereof and merge all prior discussions
between them. Neither of the

                                       14
<PAGE>

Parties shall be bound by any warranties, understandings or representations with
respect to such subject matter other than as expressly provided herein, in prior
written agreements, or in a writing executed with or subsequent to the execution
of this Agreement by an authorized representative of the Party to be bound
thereby.
