and to take such other actions as may be required to effect the following:

                  (a) The Existing Patents listed on Schedule 2.3A hereto shall
         be owned exclusively by GENUITY;

                  (b) The Existing Patents listed on Schedule 2.3B hereto shall

         3.4. Other Intellectual Property.

Other Intellectual Property, ownership by any party hereto of any and all right,
title and interest in and to Other Intellectual Property shall be determined in
accordance with applicable law and/or any agreements into which such party has
entered with its employees, subcontractors, agents or other third parties

         (b) In certain circumstances, it may be possible to obtain Other
Intellectual Property in and to Jointly-Owned Non-Statutory Intellectual
Property. Notwithstanding joint ownership of Jointly-Owned Non-Statutory
Intellectual Property, the right to seek any Other Statutory Intellectual
Property on the Jointly-Owned Intellectual Property, and the ownership in and to
any right, title and interest of any such Other Intellectual Property that may
result, shall be determined in accordance with the following:

         (i)      for any and all Other Intellectual Property in and to works of
                  authorship and mask works that are Jointly-Owned Non-Statutory
                  Intellectual Property, the party or parties that employ at
                  least one author of such work (or in the case of a
                  work-for-hire, one contributor to such work) immediately after
                  the Effective Date shall have the right to seek such Other
                  Intellectual Property in and to such works and shall
                  exclusively own, as between the parties, all right, title and
                  interest in and to any Other Intellectual Property that result

                                       4
<PAGE>

         (ii)     in the event of multiple authors and/or contributors, as the
                  case may be, at least one of which authors and/or contributors
                  is employed immediately after the Effective Date by each of
                  the parties hereto, all right, title and interest in and to
                  such Other Intellectual Property that results therefrom shall
                  be jointly owned by both parties, without the obligation of
                  either party to account to the other therefor; and

         (iii)    in the event that the author(s) or contributor(s), as the case
                  may be, is not employed by any of the parties hereto, all
                  right, title and interest in and to such Other Intellectual
                  Property that results therefrom shall be jointly owned by
                  GENUITY and GTE, with neither party having a duty to account
                  to the other for the exploitation thereof.

         3.5. Preparation, Prosecution and Enforcement of Intellectual Property
Rights. Except as provided below for jointly-owned Intellectual Property Rights,
the owner of the Intellectual Property Rights, at its expense, shall control the
preparation, filing and prosecution of any patent applications directed to such
Intellectual Property Rights and to the maintenance and enforcement of any
patents that result therefrom, and the other party hereto shall cooperate with
the owner in such efforts at the owner's reasonable request and expense. For
purposes of Intellectual Property Rights which are jointly owned, GTE shall
control the preparation, filing and prosecution of such Intellectual Property
Rights and the cost thereof shall be borne equally by GTE and GENUITY; provided,
however, that (i) GTE will consult with GENUITY regarding the choice of foreign
jurisdictions in which to protect such Intellectual Property Rights; (ii) GTE
will provide copies of all documents filed with or received from the relevant
patent or other government offices in connection with the prosecution of such
Intellectual Property Rights; and (iii) the choice of prosecution counsel shall
be reasonably satisfactory to GENUITY. If GTE refuses to file a patent
application for protection of any such jointly owned Intellectual Property
Rights after GENUITY has requested that GTE do so, GENUITY may do so, with
counsel reasonably satisfactory to GTE, and the cost thereof shall be borne
equally by GTE and GENUITY.

         3.6. Limitations and Obligations of Ownership.

         (a) Each party shall have the right, but not the obligation, to obtain,
maintain and enforce any Intellectual Property Rights solely owned by such party
in such manner as such party deems appropriate in its sole discretion.

         (b) To the extent any party hereto has any right, title or interest in
or to any Intellectual Property Right that is to be owned jointly or exclusively
by the other party in accordance with the terms of this Section 0, such first
party shall assign, and hereby assigns, to such other party such portion or all
of the first party's right, title and interest in and to such Intellectual
Property Right as required hereunder. The first party shall execute and procure
such documents and take such other actions as may be reasonably requested from
time to time by the other party to obtain for its own benefit such Intellectual
Property Rights or otherwise to transfer or confirm its Intellectual Property
Rights.

         (c) For any and all jointly owned Intellectual Property Rights, subject
to the obligations of Confidentiality set forth in Section 0 hereof:

                  (i) Each party shall have an undivided joint interest with the
         other party in and to all such jointly owned Intellectual Property
         Rights.

                  (ii) Each party shall have the right to license or sublicense
         jointly owned Intellectual Property Rights without any duty to account
         to the other party.

                  (iii) Each party shall have the right to exercise or otherwise
         exploit jointly owned Intellectual Property Rights (including, without
         limitation, the right to make, use, offer for sale, sell, and make
         versions, adaptations and derivatives works), by any manner and means
         now known or hereafter devised, in perpetuity, without any duty to
         account to the other party.

                  (iv) Each party shall obtain waivers of any and all claims
         against the other party that any employee, subcontractor or agent of
         such party may now or hereafter have in any jurisdiction under "moral
         rights" or rights of "droit moral" encompassed by any jointly owned
         Intellectual Property Rights, and to the extent that such rights may
         not be waived, each such party shall secure covenants and stipulations
         of those individuals not to assert such rights against any of the other
         parties hereto or their respective successors, assigns, licensees and
         sublicensees.

                  (v) If either party becomes aware of any infringement, misuse
         or misappropriation of any jointly owned Intellectual Property Right,
         or any attempt to invalidate any jointly owned Intellectual Property
         Right, such party shall promptly notify the other party, and the
         parties shall thereafter confer in good faith regarding the steps, if
         any, that should be taken to remedy any such infringement, misuse or
         misappropriation or any such invalidity attempt. Either party shall
         have the right, at its sole discretion and expense, to enforce any
         jointly owned Intellectual Property Right against a third party. The
         other party shall reasonably cooperate in any such proceeding;
         provided, however, that the party bringing such proceeding shall
         reimburse the other party for such other party's costs and reasonable
         expenses, including reasonable attorneys fees, incurred in connection
         with such cooperation; and provided, further, that the duty of
         cooperation shall not interfere or diminish in any way with the right
         of such other party to grant licenses hereunder, including licenses to
         the accused infringer, and otherwise exploit all of such other party's
         rights in the jointly owned Intellectual Property Right.

         otherwise provide to the other party or its Affiliates any
         Jointly-Owned Non-Statutory Intellectual Property.

8. Confidential Information.

         8.1. Restrictions. The Confidential Information of the disclosing party
may be used by the receiving party only for the performance of its obligations
and the exercise of its rights hereunder and may only be disclosed to those
employees, subcontractors or agents of the receiving party who have a need to
know in order so to perform or exercise. Except and to the extent set forth in
Section 0, the receiving party may not disclose Confidential Information of the
disclosing party to any other person, entity or the public without the prior
written consent of the disclosing party; provided, however, that such
Confidential Information may be disclosed by the receiving party without the
necessity of prior written consent to the receiving party's employees,
subcontractors or consultants who require access to such Confidential
Information to perform the receiving party's obligations or to exercise its
rights hereunder; provided, however, such persons have entered into written
agreements which contain obligations of nondisclosure and nonuse no less
restrictive than set forth in this Section 0, which agreements shall be
enforceable by the disclosing party.

         8.2. Compliance with Governmental, Judicial Requirements. If a
receiving party receives a request to disclose any Confidential Information of
the disclosing party (whether pursuant to a valid and effective subpoena, an
order issued by a court or other governmental authority of competent
jurisdiction or otherwise) on advice of legal counsel that disclosure is
required under applicable law, the receiving party agrees that, prior to
disclosing any Confidential Information of the disclosing party, it shall (i)
notify the disclosing party of the existence and terms of such request or
advice, (ii) cooperate with the disclosing party in taking legally available
steps to resist or narrow any such request or to otherwise eliminate the need
for such disclosure at the disclosing party's sole expense, if requested to do
so by the disclosing party, and (iii) if disclosure is required, it shall be the

         8.3. Continuing Obligation. The obligation of nondisclosure and nonuse
with respect to Confidential Information of the disclosing party shall survive
and continue for a period of five (5) years after the Effective Date; provided,
however, that the obligations of non-disclosure and non-use shall continue in
perpetuity for software in any form.

9. Dispute Resolution.

         9.1. General. Any controversy or claim arising out of or relating to
this Agreement, or the breach thereof, shall be settled first, by good faith
efforts of the parties to reach mutual agreement as set forth below.

         9.2. Initial Resolution. A party that wishes to initiate the dispute
resolution process shall send written notice to the other party with a summary
of the controversy and a request to initiate these dispute resolution
procedures. Each party shall appoint a knowledgeable, responsible representative
from the company who has the authority to settle the dispute, to meet and
negotiate in good faith to resolve the dispute. The discussions shall be left to
the discretion of the representatives, who may utilize other alternative dispute
resolution procedures such as mediation to assist in the negotiations.
Discussions and correspondence among the representatives for purposes of these
negotiations shall be treated as Confidential Information developed for purposes
of settlement, shall be exempt from discovery and production, and shall not be
admissible in the arbitration described above or in any lawsuit pursuant to Rule
408 of the Federal Rules of Evidence. Documents identified in or provided with
such communications, which are not prepared for purposes of the negotiations,
are not so exempted and may, if otherwise admissible, be admitted in evidence in
the arbitration or lawsuit. The parties agree to pursue resolution under this
subsection for a minimum of sixty (60) days before initiating an action in the
appropriate jurisdiction; provided, however, that each party reserves the right
to pursue and defend its rights in court after the said sixty (60) day period.

         9.3. Injunctive Relief. The foregoing notwithstanding, each party shall
have the right to seek injunctive relief in an applicable court of law or equity
pending resolution of the dispute in accordance with the foregoing.

        Notice shall be deemed to have been given or made when actually

         10.2. Compliance. GTE and GENUITY shall each comply with the provisions
of all applicable federal, state, and local laws, ordinances, regulations and
codes (including, without limitation, procurement of required permits or
certificates) in fulfillment of their obligations under this Agreement. All
Intellectual Property Rights Held by either party are subject to U.S. export and
foreign transactions control regulations. Each party undertakes that it shall
neither export, nor cause nor permit to be exported, without the other party's
prior written consent and without compliance with applicable law and regulation,
any such Intellectual Property Rights of the other party out of the United
States of America, nor shall such rights be made available by such party,
directly or indirectly, for use in any project associated with the design,

facilities to produce nuclear explosives, (ii) missiles, or (iii) chemical or

and regulations relating to the exportation of technical information, as they
currently exist and as they may be amended from time to time.

         10.3. Assignment, Subcontracting. Neither this Agreement nor any rights
or obligations hereunder shall be assignable by either of the parties without

assign this Agreement to any Affiliate or to any purchaser of any of such party
or of such party's business to which such license relates upon the sale of all
or substantially all of the assets of such business or upon a merger, stock swap
or other means by which a third party acquires that part of such party's
business to which such license relates. Any attempted or purported assignment in
violation of the foregoing shall be void. Subject to the foregoing, this
Agreement shall be binding upon and inure to the benefit of the successors and
permitted assigns of each party hereto.

         10.4. Waiver of Terms and Conditions. Failure to enforce any of the
terms or conditions of this Agreement shall not constitute a waiver of any such
terms or conditions, or of any other terms or conditions.

                                       12
<PAGE>

         10.5. Severability. Where any provision of this Agreement is declared
invalid, illegal, void or unenforceable, or any changes or modifications are
required by regulatory or judicial action, and any such invalid, illegal, void
or unenforceable provision, or such change or modification, substantially
affects any material obligation of a party hereto, the remaining provisions of
this Agreement shall remain in effect and the parties shall mutually agree upon
a course of action with respect to such invalid provision or such change or
modification to the end that the purposes of this Agreement are carried out.

         10.6. Governing Law. This Agreement, and the rights and obligations
contained in it, shall be governed by and construed in accordance with the laws
of the State of New York, without regard to any conflicts of law principles that
would require the application of the laws of any other jurisdiction.

         10.7. No Unreasonable Delay or Withholding. Where agreement, approval,
acceptance, consent or similar action by GENUITY or GTE is required, such action
shall not be unreasonably delayed or withheld.

         10.8. Force Majeure. If performance of any obligations by either party
under this Agreement is prevented, restricted or interfered with by reason of
acts of God, wars, revolution, civil commotion, acts of public enemy, embargo,
acts of government in its sovereign capacity, labor difficulties, including,
without limitation, strikes, slowdowns, picketing or boycotts, communication
line failures, power failures, or any other circumstances beyond the reasonable
control and not involving any fault or negligence of the party affected, the
party affected, upon giving prompt notice to the other party, shall be excused
from such performance on a day-to-day basis during the continuance of such
prevention, restriction or interference (and the other party shall likewise be
excused, on a day-to-day basis during the same period, from performance of its
obligations which are dependent upon or affected by such nonperformance);
provided, however, that the party so affected shall use its best reasonable
efforts to avoid or remove such causes of nonperformance and both parties shall
proceed immediately with the performance of their obligations under this
Agreement whenever such causes are removed or cease.

         10.9. Entire Agreement. This Agreement represents the entire
understanding between the parties with the respect to its provisions and cancels
and supercedes all prior agreements or understandings, whether written or oral,
with respect to the subject matter. This Agreement may only be modified or
amended by an instrument in writing signed by duly authorized representatives of
the parties. This Agreement shall be deemed to include all Schedules attached
hereto.

The Scope of this Agreement as listed in Section reads as follows:

GTE will provide, through its Network Operations Center ("NOC"), network
monitoring of network enabling devices and processes twenty four (24) hours a
day, seven (7) days a week, three hundred sixty-five (365) days a year to
detect, escalate, restore, and follow-up on anomalies occurring in the network.
In addition, GTE will provide technical support to GNI for problems that cannot
be resolved on-site; these support services include network element event
problem resolution, network element reliability analysis and network traffic
management.

The following definitions are provided to further define the scope and explain
the intended meanings to be associated with terms used.

The network enabling devices to be monitored include the hardware and software
products that allow voice, data, or video access to the public communications
network and/or a private communications network and includes, but is not limited
to, the monitoring of switches, routers, fiber, video, lightwave multiplexing
equipment, digital cross connections, servers and hubs.

Detection is the identification, via informational indicators, of changing
conditions in the above mentioned devices.

Escalation is the referral of problems within a hierarchy to facilitate
resolution.

Restore is to eliminate conditions that are detrimental to normal operating
conditions.

Follow-up is verifying that steps were taken in the proper manner concerning a
detrimental condition and that such condition has not recurred.

An anomaly is an irregularity in the network.

Technical support is expertise that can be offered either on site or by
telephone to assist others in performing their duties.

Network element event problem resolution.  Once a problem is identified, it goes
through the necessary steps to be restored.

Network element reliability analysis.  Analysis of information data pertaining
to the operation or condition of a network element.

Network traffic management.  Management of the flow of traffic between network
elements or switches to prevent degradation of service.  In the event
<PAGE>

circumstances exist that may potentially cause a degradation of service, the NOC
will, at its sole discretion, reroute traffic in the network.
