       THE FOREGOING NOTWITHSTANDING, THE WARRANTIES AND REPRESENTATIONS OF
       SECTION 2.7 OF THE MERGER AGREEMENT SHALL CONTINUE IN ACCORDANCE WITH THE

                  ARTICLE 5 - CONFIDENTIALITY AND PROTECTION OF
                    INTELLECTUAL PROPERTY LICENSED HEREUNDER

5.1    CONFIDENTIALITY. Each Party agrees that, except as required by applicable
law (provided timely notice thereof has been given to the other Party to prevent
or limit disclosure or to seek appropriate protective orders) or as expressly
set forth herein, Licensed Intellectual Property, Business Statutory
Intellectual Property and Proprietary Business Information of the other Party
shall not be divulged or otherwise made available to any Person, other than to
the recipient Party and its Affiliates and Persons performing services for the
recipient Party or its Affiliates, provided such Persons have agreed in writing
not to further disclose or use such Licensed Intellectual Property, Business
Statutory Intellectual Property and Business Information. The foregoing
obligations shall not apply to that portion of Licensed Intellectual Property,
Business Statutory Intellectual Property and Proprietary Business Information
that (i) becomes generally available and known to the public, without
restriction on use or disclosure, (ii) is rightfully received from a third
Person without restrictions on use or disclosure, (iii) is independently
developed by or for the Party without reference to or use of the other Party's
Licensed Intellectual Property, Business Statutory Intellectual Property or
Proprietary Business Information, or (iv) is the subject of prior written
approval of the other Party.

5.2    NOTICES OF INFRINGEMENT. Each Party shall promptly notify the other Party
in writing if it receives any notice of, or becomes aware of, any actual
infringement, misappropriation or misuse by any Person of the Business Statutory
Intellectual Property (notice only to Company) or Licensed Intellectual Property
(notice only to Verizon Companies).

5.3    ASSISTANCE. At a licensor's request and expense, the licensee(s) shall
take all reasonable steps and shall provide such materials, cooperation and
assistance as may be reasonably required to assist such licensor in maintaining
and enforcing Intellectual Property owned by such licensor and licensed
hereunder.

5.4    LICENSOR'S RIGHT TO ENFORCE. Each licensor shall have the right (but not
the obligation) to take action at its own expense against actual or suspected
infringers of the Intellectual Property it owns in which it has granted rights
to the licensee(s). No licensee shall have the right to, or may take actions to
enforce the Intellectual Property licensed to it hereunder without licensor's
consent.

               ARTICLE 6 -- RIGHTS AND OBLIGATIONS WITH RESPECT TO
                       JOINTLY-OWNED INTELLECTUAL PROPERTY

6.1    CONFIDENTIALITY. Each Party and its Affiliates shall treat and maintain
the Jointly-Owned Intellectual Property in accordance with the same
confidentiality and non-disclosure policies as it treats the rest of its
Intellectual Property of a similar nature, but in no event will any Party use
less than reasonable care in protecting the confidentiality thereof.

6.2    STATUTORY PROTECTION. Either Party may seek statutory protection for any
of the Jointly-Owned Intellectual Property within a period of six (6) months
after the Closing Date, provided such Party notifies the other Party or Parties,
and Company shall have the first option, at its expense, to assume prosecution
responsibility for obtaining and maintaining statutory protection for such
Jointly-Owned Intellectual Property. If Company elects not to exercise such
option, then it shall notify the Verizon Companies of such election, and the
Verizon Companies may, at their expense, assume such responsibilities. The Party
that assumes such responsibility ("Prosecuting Party") shall keep the other
Parties fully informed concerning prosecution or maintenance of such
Jointly-Owned Intellectual Property by providing copies of all communications
with the appropriate registration authorities and by giving such Parties an
opportunity to comment on such communications. Each Party shall provide
reasonable cooperation to assist the Prosecuting Party's efforts, at the
Prosecuting Party's expense, to obtain and maintain statutory protection for the
Jointly-Owned Intellectual Property, including providing information and causing
the execution of any assignments and other instruments or documents as are
reasonably necessary or appropriate to carry out the intent of this Section.

6.3    OWNERSHIP OF STATUTORY INTELLECTUAL PROPERTY FOR JOINTLY-OWNED
INTELLECTUAL PROPERTY. If any Party seeks statutory protection for Jointly-Owned
Intellectual Property by filing a patent or copyright application within a
period of six (6) months after the Closing Date, then (i) such Jointly-Owned
Intellectual Property shall be deemed Business Statutory Intellectual Property
and shall be subject to all provisions governing Business Statutory Intellectual
Property herein (including sole ownership of such Business Statutory
Intellectual Property by the Company, subject to the license granted by the
Company to the Verizon Companies in Section 2.1(a)), and (ii) Company shall be
listed in all applications or registrations as the sole owner of such Business
Statutory Intellectual Property. Verizon Companies and their Affiliates shall
continue to have an undivided joint ownership interest in the Jointly-Owned
Intellectual Property (as set forth in Section 2.1(c) hereof), provided that the
use of such Jointly-Owned Intellectual Property shall be subject to the
restrictions, if any, imposed by the license for Business Statutory Intellectual
Property granted to Verizon Companies and their Affiliates pursuant to Section
2.1(a) hereof.

                      ARTICLE 7 - TERMINATION/CANCELLATION

7.1    NO WAIVER. No waiver of any breach of, or default under, this
Intellectual Property Agreement shall constitute a waiver of any other breach
of, or default under, this Intellectual Property Agreement, and no waiver shall
be effective unless made in writing and signed by an authorized representative
of the Party waiving the breach or default.

7.2    BANKRUPTCY. The Parties agree that the rights and licenses under any
Intellectual Property shall not be deemed to be executory contracts, but shall
be deemed licenses of "intellectual property", for purposes of Section 365(n) of
the Bankruptcy Act and any rights or terms granted under this Intellectual
Property Agreement pursuant thereto shall not be terminable, in whole or in
part, pursuant to this Section 7.2. If any Party voluntarily files for
bankruptcy or makes an assignment for the benefit of its creditors, or an
involuntary assignment or bankruptcy petition is made or filed against such
Party, any other Party may immediately terminate this Intellectual Property
Agreement and the licenses granted herein. In the event of a licensor's
bankruptcy, treatment of the grant of rights and licenses as executory contracts
and a subsequent rejection or disclaimer of this Agreement by a bankruptcy
trustee or by licensor as a debtor-in-possession, whether under the law of the
United States or in the event of a similar action under applicable law, licensee
may elect to retain its license rights, subject to and in accordance with the
provisions of the United States Code, Title 11, Section 365(n) or other
applicable law.

7.3    ACTIONS FOR BREACH. In the event of any breach of this Intellectual
Property Agreement by either Party, the other Party shall have the right to seek
specific performance of the obligations of the breaching Party under this
Agreement. If a licensee commits a material breach of this Intellectual Property
Agreement, the applicable licensor may seek damages if licensee fails to cure
such breach within thirty (30) days after receiving notice of such breach from
such licensor; provided, however, that such licensor shall not, under any
circumstances, terminate this Intellectual Property Agreement or prevent any
licensee from using the Intellectual Property to which it has been granted
rights hereunder.

7.4    EFFECT OF TERMINATION. Any termination pursuant to Section 7.2 by one
Party of this Intellectual Property Agreement or the licenses granted hereunder
shall have no effect on the title, rights and licenses conveyed to the other
Party, and the Parties agree that the title, rights and licenses of the
non-bankrupt Party shall survive and continue after any termination of this
Intellectual Property Agreement.

                         ARTICLE 8 - GENERAL PROVISIONS

8.1    MERGER AGREEMENT PROVISIONS. Except and to the extent expressly provided
herein, the provisions of Article X (General) of the Merger Agreement shall
apply to this Intellectual Property Agreement and such provisions are expressly
incorporated herein.

8.2    ASSIGNABILITY. No Party shall assign this Agreement or its rights and
obligations hereunder to any Person without the prior written consent of the
other Parties which consent will not be unreasonably withheld, unreasonably
delayed, or unreasonably conditioned; provided, however, that any Party, or any
Affiliate to whom rights have been sublicensed hereunder, may assign, in whole
or in part, its rights and obligations pursuant to this Agreement to (a) one or
more of its Affiliates, or (b) any subsequent purchaser of such Party or such
Affiliate or any material portion of its assets to which the licenses granted
hereunder apply (whether such sale is structured as a sale of stock, a sale of
assets, a merger or otherwise). Company shall have the right to use Business
Statutory Intellectual Property, Jointly-Owned Intellectual Property and

                                  Page 12 of 19
<Page>

Licensed Intellectual Property for purposes of creating a security interest in
favor of any of the lenders who are providing financing in connection with
Buyer's acquisition of the Stock pursuant to the Merger Agreement; provided,
however, that such security interest in Business Statutory Intellectual Property
and Jointly-Owned Intellectual Property shall not affect the rights and licenses
granted to Verizon Companies or their Affiliates and that such security interest
in Licensed Intellectual Property shall not expand the rights and licenses
granted pursuant to Section 2.1(b) hereof nor permit the separate sublicense or
other conveyance of such rights and licenses in Licensed Intellectual Property
to anyone other than permitted successors and assigns.

8.3    EXPORT CONTROL COMPLIANCE. From and after the Closing Date, each Party
shall comply with all applicable requirements of the Export Control Act, as it
may be amended from time to time, relating to the Intellectual Property conveyed
or licensed hereunder.

8.4    SURVIVAL. The provisions of Articles 1, 7 and 8 and Sections 2.1(c)-(g),
3.1, 4.1, 4.2, 5.1, 5.3, 6.1, 6.3 and 8.4 shall survive the termination of this
Intellectual Property Agreement.

8.5    SUCCESSORS AND ASSIGNS. This Intellectual Property Agreement shall also
be binding upon and inure to the benefit of each Party's respective heirs,
administrators, executors, successors, legal representatives and permitted
assigns.
