3	OWNERSHIP OF INTELLECTUAL PROPERTY
3.1	Ownership of Deliverables.  Subject to the terms of the applicable Work
Statement and the restrictions set forth below, Telcordia grants to CTC
a perpetual, royalty free personal, nontransferable, nonexclusive
license to use and copy the Deliverables for CTC's internal business
purposes. This license will include a license to use any Telcordia
newly-created Invention (as defined below), Work of Authorship (as
defined below) or other intellectual property to the extent necessary
for CTC to meet the purposes set forth in this Agreement or in an
applicable Work Statement.  This license will further include the right
to provide copies of the Deliverable to consultants, contractors or
suppliers who are hired to carry out recommendations within the
Deliverable as long as such consultant, contractor or supplier is
subject to an agreement with CTC requiring confidentiality of the
Deliverable, and which limits the use of the Deliverable by the
consultant, contractor or supplier solely to providing services to CTC
and which confidentiality terms are no less protective than those
contained in this Agreement. CTC shall include Telcordia's copyright
notice on all copies of Deliverables. Except as otherwise provided in a
Work Statement, a Professional Services Attachment or another written
agreement between the Parties, the Services and any Deliverables are
not "work for hire." Nothing contained herein shall be deemed to
prohibit CTC for using the Deliverables, Inventions, Works of
Authorship or other intellectual property to provide integrated
telecommunications services to its customers.
3.2	Ownership of Newly-Created Intellectual Property. Any patentable or
unpatentable discoveries, ideas, including methods, techniques, know-
how, concepts, or products ("Invention"); or any works fixed in any
medium of expression, including copyright and mask work rights ("Works
of Authorship"); or any other intellectual property created by
Telcordia during the course of the Services, shall be the sole and
exclusive property of Telcordia.  Any Inventions, Works of Authorship
or other intellectual property created jointly by Telcordia and CTC
during the course of the Services shall be the joint property of
Telcordia and CTC, each Party having full licensing rights with no
obligation of accounting to the other Party. Any Inventions, Works of
Authorship or other intellectual property created jointly by Telcordia
and CTC during the course of the Services shall be the joint property
of Telcordia and CTC, each Party having full licensing rights with no
obligation of accounting to the other Party, including with respect to
any patents or patent applications related thereto that are filed in
any country based on such subject matter (together "Joint Patents").
Any and all Joint Patents shall be jointly assigned to Telcordia and
CTC, each without any obligation to account to the other.  Telcordia
and CTC shall each have the sole right to determine what patents, if
any, will be obtained on its employees' or consultants' inventions.
With respect to Joint Patents, Telcordia and CTC will agree in writing,
on a case by case basis, which Party will file patent applications, if
any.  Telcordia and CTC shall each bear its own patent filing expenses.
Telcordia and CTC shall each have the right to independently license
its patent rights and technical information resulting from the Joint
Patents, including jointly owned technical information, without
accounting to the other Party.  Inventions are jointly made when
employees or consultants of  both Telcordia and CTC contribute to the
Joint Patents.

3.3	No Rights By Implication.  No direct or indirect ownership interest or
license rights in Inventions or Works of Authorship are created by
implication. Except as specifically set forth in Sections 2 and 3.1, no
direct or indirect ownership interest or license rights in any software
or patents are granted by either Party in this Agreement. Except as
specifically set forth in Sections 2 and 3.1, any grant of an ownership
interest or license rights in a patent or software must be negotiated
in a separate agreement.
3.4	Similar Work for Other Customers.  Telcordia may perform the same or
similar Services for others, including providing the same or similar
conclusions and recommendations, provided that CTC Confidential
Information is not used or disclosed.
3.5	Option for CTC Ownership.  In the event that CTC desires ownership of a
Deliverable related to a Professional Services  Attachment, the Parties
agree that they will discuss in good faith appropriate terms and
conditions for such ownership prior to the execution of the affected
Professional Services Attachment, including, but not limited to, CTC
ownership of the copyright in the Deliverable, CTC ownership of newly
created intellectual property in the Deliverable, retention by
Telcordia of pre-existing intellectual property, licenses back to
Telcordia of the intellectual property, and appropriate assignment
provisions to effect such ownership rights.  All such CTC ownership
provisions shall be clearly set forth in the Professional Services
Attachment.  CTC understands that any ownership rights in a
Professional Services Deliverable will affect the price for such
Deliverable and the Services associated therewith. Telcordia agrees
that any price adjustment for Services or Deliverable shall be
reasonable taking into account the circumstances.
4	FEES AND PAYMENTS
4.1	Fees.  CTC shall timely pay the fees for the Licensed Software and any
Maintenance and Services as specified in any Work Statement.
4.2	Expenses. Except as otherwise set forth in this Agreement and to the
extent set forth in the applicable Work Statement, CTC shall also

expenses actually incurred in connection with the Services, including,
but not limited to, travel, lodging, meals and telephone costs.
Telcordia shall obtain CTC's prior written approval for any single
expense (other than for travel, lodging and meals) over $2500.00.
Telcordia shall submit copies of receipts for all amounts greater than
or equal to twenty five dollars ($25).
4.3	Billing. Telcordia shall submit a single monthly invoice to CTC for
Services and reimbursement of expenses. CTC shall pay billed amounts
within thirty (30) days of the date of the bill. Any payment not
received by the expiration of this thirty (30) day period, shall
constitute an overdue payment ("Overdue Payment").
4.4	Payments. Payments to Telcordia shall be in United States dollars and
may be either:
a)	wire transferred to:
	First Union National Bank
550 Broad Street

b) 	mailed to Telcordia Technologies, Inc.  P.O. Box 18192, Newark, New
Jersey 07191.

4.5	Overdue Payments.  Overdue Payments are subject to a late payment
charge, calculated and compounded monthly, and calculated at an annual
rate of one percent (1%) over the lowest prime rate available in New
York City, as published in The Wall Street Journal on the first Monday
(or the next bank business day) following the payment due date.   If
the amount of the late payment charge exceeds the maximum permitted by
law, the charge will be reduced to that maximum amount.
4.6	Taxes. CTC shall pay or reimburse Telcordia for all sales or use taxes,
duties, or levies imposed by any authority, government or government
agency (other than those levied on Telcordia's net income imposed in
the United States) in connection with this Agreement.  If Telcordia is
required to collect a tax to be paid by CTC, CTC shall pay this tax
within three (3) business days of demand.  If CTC fails to pay these
taxes, duties or levies, CTC shall pay all reasonable expenses actually
incurred by Telcordia, including reasonable attorney's fees, to collect
such taxes, duties or levies.
4.7 	Records and Audit.   From time to time, but not more than once
annually, Telcordia may request that CTC provide a certification to the
effect that actual use of the Licensed Software and fees paid are in
compliance in all material respects with the terms of this Agreement.
In addition, Telcordia may once each calendar year, upon reasonable
written notice, perform an audit during normal business hours of the
appropriate records of CTC relative to this Agreement to verify that
the actual use of the Licensed Software, Deliverables and fees paid are
in compliance in all material respects with the terms of this
Agreement.   Such audit shall be at Telcordia's expense. In the event
such audit reveals in Telcordia's reasonable judgement that CTC is not
in compliance in all material respects with the terms of this
Agreement, CTC shall reimburse Telcordia for the cost of the audit, and
immediately remedy such non-compliance.
5	CONFIDENTIAL INFORMATION
5.1		Confidentiality.
a)	CTC shall hold the Licensed Software, (including the methods and
concepts utilized in the Licensed Software) and Deliverables in
confidence for the benefit of Telcordia as confidential information.
Both Parties undertake not to copy, divulge, distribute, reveal,
communicate, transcribe by any means or form and not to make known
directly or indirectly to any Third Party, through their personnel, the
information furnished by either one of the Parties or the information
to which they have had access by virtue of this Agreement, including,
but not limited to, the Licensed Software, Documentation, Services and
Deliverables provided under this Agreement, except with the written
authorization of the Party issuing the information , which
authorization shall not be unreasonably withheld or delayed.  In
addition, neither Party   shall not disclose to Third Parties the
methodology, procedures, handbooks and Confidential Information
obtained from the other Party pursuant to this Agreement, including,
but not limited to, the Inventions and Works of Authorship, unless a
prior written authorization has been issued by Telcordia, which
authorization shall not be unreasonably withheld or delayed.
b)	In addition, both Parties consider as confidential all the information
received from the other Party relative to this Agreement which is
marked as confidential or proprietary, and undertake to implement the
measures that they usually apply for the protection of the secrecy of
their own documents and information, but in no event measures which are
less than reasonable care in protecting such confidential information.
c)	In particular, both Parties shall inform the members of their staff who
have access to:  (i) the Licensed Software; (ii) the information
related to the Licensed Software; and (iii) the documents and
information furnished by the other Party, of the prohibition to divulge
or make any of the above known to Third Parties, whether totally or
partially, in any manner whatsoever.  By the mere fact of executing
this Agreement, each Party commits to inform their personnel having
access to the above of the obligation contained in this Section 5.
d)	No information of the disclosing Party will be considered confidential
to the extent the information:
i)	is in the public domain  through no fault of the recipient either
before or after disclosure; or
ii)	is in the possession of the recipient prior to the disclosure, or
thereafter is independently developed by recipient's employees or
consultants who have had no prior access to the information; or
iii)	is rightfully received from a Third Party without breach of any
obligation of confidence.
5.2	Disclosure of Confidential Information.
 	Each Party agrees to protect the confidentiality of the Licensed
Software and Deliverables, including taking adequate actions to
instruct its employees, consultants and contractors who will have
access to the Licensed Software and Deliverables, and to obtain their
compliance with the obligations set forth in this Agreement.  CTC
agrees that, prior to receipt of any Telcordia Licensed Software,
Deliverables or other confidential information, each of  its employees,
contractors and consultants will have signed an agreement with CTC
which provides at least a substantially similar level of protection to
the Telcordia information as the level of protection required under
this Agreement, but no less than a reasonable level of protection. The
confidentiality obligations of CTC and its employees, contractors and
consultants. The confidentiality obligations of each Party and its
employees, contractors and consultants survive the termination or
expiration of the corresponding Work Statement or Professional Services
Attachment or expiration of  this Agreement for a period of two (2)
years, except with respect to Licensed Software and the associated
Documentation as to which there shall be no limitation on the survival
of such obligations.
5.3	No Copies of Licensed Software.  Except as otherwise set forth in this
Agreement or the applicable Work Statement, no copies may be made of
the Licensed Software without Telcordia's prior written permission.
However, CTC may make a reasonable number of archival or backup copies
of the Licensed Software and Documentation for use within the scope of
the permitted use of the Licensed Software.  CTC shall also reproduce
all Telcordia proprietary legends when making such copies.
5.4	Title. Title to the Licensed Software, including all modifications made
to the Licensed Software, shall remain with Telcordia and thereby are
not transferred to CTC.
5.5	Notification Obligation.  If the receiving Party has actual or
constructive notice of any unauthorized use or disclosure of the
Confidential Information of the disclosing Party, the receiving Party
shall promptly and fully notify the disclosing Party of all facts known
to it concerning such unauthorized use or disclosure.
5.6	Misuse of Confidential Information. Either Party's failure to fulfill
the obligations and conditions with respect to any use, disclosure,
publication, release, or dissemination to any third person of the other
Party's confidential information or breach of any restrictions or
obligations of any licenses granted by the other Party, constitutes a
material breach of this Agreement.  In that event the aggrieved Party
may, at its option and in addition to any other remedies that it may
have, terminate this Agreement, its obligations and any rights or
licenses granted, upon ten (10) days written notice to the other Party.
In addition to any other remedies it may have, the aggrieved Party has
the right to demand the immediate return of all copies of Confidential
Information provided to the other Party under this Agreement.  The
Parties acknowledge and agree that any breach of this Section 5 will
cause immediate and irreparable injury to the non-breaching Party, and
that monetary damages shall be inadequate to compensate for such
breach.  In the event of such breach, the injured Party shall be
entitled to injunctive relief, in addition to any and all other
remedies as may be available at law or in equity.
5.7	Required Disclosure The receiving Party will promptly inform the
disclosing Party of any requirement or request by any Third Party that
Confidential Information be disclosed pursuant to legislation, legal
directive, public regulation, court decision, governmental order or
similar legal requirement or in connection with the pursuit or defense
of a claim in order to afford the disclosing Party an opportunity to
limit or restrict such disclosure or to obtain its agreement prior to
further action.
6	TELECOMMUNICATIONS ACT
6.1	CTC acknowledges and agrees that Telcordia has informed and explained
to CTC the provisions of the Telecommunications Act of 1996 of the
United States of America ("the Act"), under which a competent authority
of that country may instruct Telcordia to terminate a Work Statement.
Telcordia shall use commercially reasonable efforts to contest such
instruction in the proper forum and maintain the Work Statement in full
force and effect.  CTC therefore recognizes that if Telcordia should
receive instructions to that effect, so long as Telcordia shall have
made the above-described efforts, Telcordia shall have the right to
immediately terminate the affected Work Statement without liability
upon sending a written notice to CTC.

7	ACCEPTANCE OF LICENSED SOFTWARE
7.1	Acceptance of Supported Software.  During the Acceptance Period, CTC
may perform the Acceptance Tests to determine whether the Supported
Software performs in conformance with the Acceptance Criteria. CTC
shall be deemed to have accepted the Supported Software ("Acceptance")
in any of the following instances: (i) the Supported Software  conforms
with the applicable Acceptance Criteria (as defined in the preceding
sentence); (ii) CTC expressly waives the Acceptance Tests in writing;
(iii) CTC uses the Supported Software in a commercial production
environment; or (iv) CTC fails to notify Telcordia in writing that the
Supported Software does not conform to the Acceptance Criteria .  The
occurrence of any of the events described in this Section 7.1 shall
constitute acceptance of Supported Software ("Acceptance").  The
Acceptance process described in this Section 7.1, shall not apply to
Maintenance Releases (as defined in Exhibit D) provided under Sections
9.1, 9.2, and 9.3 of this Agreement.
7.2	Execution of Acceptance Test.  At its option, Telcordia shall be
allowed to reasonably participate in the execution of the Acceptance
Tests for the Supported Software at no additional charge to CTC, solely
to facilitate the timely execution of the Acceptance Tests and the
Restoration or Resolution  (as defined in Exhibit D) of Severity 1 or
Severity 2 Defects (as defined in Exhibit D), if any.  If the
applicable Work Statement does not provide for such participation and
it is not requested by Telcordia, then at CTC's request, such
participation shall be provided at Telcordia's then-current standard
hourly rates, subject to availability, pursuant to the change process
defined in Section 13 of this Agreement.
7.3	Retest Procedure.  If during the Acceptance Period, CTC advises
Telcordia that the Supported Software does not perform in conformance
with the Acceptance Criteria, then Telcordia shall provide a
Restoration or Resolution (as defined in Exhibit D to the Agreement)
for those non-conformances that would be classified as Severity 1 or
Severity 2 Defects pursuant to Exhibit D to the Agreement. Unless
otherwise agreed in a Work Statement, such Restoration or Resolution
will be provided within a reasonable time period as determined by
Telcordia, and in no event shall this time period be greater than
thirty (30) calendar days following the date CTC identified such
Defects to Telcordia. Acceptance testing shall nevertheless continue by
working around such Defects to the extent technically and commercially
reasonable.  If Telcordia is unable to provide a Restoration or
Resolution for such Defects within the Acceptance Period, the
Acceptance Period shall be deemed extended a reasonable period of time
(which shall be a time period following Restoration or Resolution which
is no longer than the duration of the original Acceptance Period) to
allow CTC to re-perform the Acceptance Tests such additional testing
will begin immediately following Telcordia's provision of such
Restoration or Resolution.
7.4	Remedies.  If Telcordia is unable to provide a Restoration or
Resolution for such Severity 1 or Severity 2 Defects within the time
period set forth in Section 7.3 above, and CTC advises Telcordia that
the Supported Software does not perform in accordance with the
applicable Acceptance Criteria due to Severity 1 or 2 Defects, CTC
shall have the right to either: a) further extend the Acceptance Test
period until Telcordia has provided a Resolution or Restoration for
such Severity 1 or 2 Defects, not to exceed an additional thirty days,
during which time Telcordia will assign a senior engineer to be on-site
at CTC's testing location to assist with such efforts at no additional
charge to CTC; or b)  terminate the applicable Work Statement for the
Supported Software without further liability, other than as provided in
Section 5 of this Agreement,  provided that CTC gives Telcordia written
notice of such termination within 30 days following the original or
extended Acceptance Period, as applicable. Telcordia's sole obligation,
and CTC's sole and exclusive remedy against Telcordia due to the
inability of the Supported Software to perform in accordance with the
Acceptance Criteria shall be: i) a refund of the license fee for and
any fixed price fees for Services in connection with such Supported
Software, if any, which has been paid to Telcordia under the applicable
Work Statement; ii) reimbursement of CTC for any Third Party software
license fees paid by CTC for software licensed by CTC  only for use
with such Supported Software; and iii) reimbursement of CTC for the
then-current fair market value of any Third Party hardware purchased by
CTC only for use with such Supported Software, provided that CTC: a)
returns all full and partial copies of such  Supported Software to
Telcordia; b) assigns the licenses to such Third Party software to
Telcordia, if CTC is permitted to do so under its license agreement for
such software, or returns such Third Party software to the
corresponding vendor; and c) cooperates with Telcordia in reselling
such Third Party Software with the understanding that Telcordia's
reimbursement of CTC for such hardware shall be limited to the
difference between the amount of such resale and the fair market value,
including depreciation, of such hardware at that time.
7.5	Acceptance of Non-Supported Software. Unless otherwise stated in the
applicable Professional Services Work Statement or Professional
Services Attachment, all Non-Supported Software will be deemed accepted
by CTC upon delivery.
8	WARRANTY AND DISCLAIMER OF WARRANTIES
8.1	Warranty for Supported Software and Basic Maintenance Services.
Telcordia warrants that (i) the Supported Software, will conform to the
Documentation under normal use conditions during the twelve (12) month
period following Acceptance ("Warranty Period"); and (ii) if the
Supported Software fails to perform as a result of defective media
during the Warranty Period, Telcordia shall replace the media within
ten (10) business days from CTC's notification to Telcordia of such
defective media.  Telcordia shall correct the Supported Software's non-
conformance with the Documentation as set forth in (i) of the preceding
sentence in accordance with the Basic Warranty and Maintenance Service
procedures set forth in Exhibit D to this Agreement. The warranty
contained herein shall apply only to the Supported Software for which
CTC is current in its Maintenance payment obligations, and shall not
apply to any Supported Software that has been modified without prior
written authorization from Telcordia. As CTC's sole and exclusive
remedy for such non-conformity in the event that Telcordia is delayed
in correcting the Supported Software as described above, CTC shall be
entitled to credits that will be applied against the next Maintenance
invoice as described in the Maintenance Exhibit D. Except as otherwise
provided in the applicable Work Statement, prior to the expiration of
the Warranty Period, CTC may request continued Basic Warranty and
Maintenance Support Services for the Supported Software at Telcordia's
then current rates by contacting Telcordia's Technical Contact. CTC's
purchase of continued Basic Warranty and Maintenance Support Services
requires mutual execution of a separate Work Statement to this
Agreement.
8.2	Year 2000 Software Functionality Warranty. Telcordia warrants that the
Supported Software will record, store, process, recognize, calculate
and display calendar dates falling on or after January 1, 2000 in the
same manner, and with the same functionality, that it records, stores,
recognizes, calculates, and displays calendar dates falling on or
before December 31, 1999.  If a breach of the warranty set forth in
this Section 8.2 occurs, CTC's sole and exclusive remedy is that
Telcordia will provide a Restoration or Resolution for such Defect as
provided in Exhibit D to this Agreement during any period in which CTC
is entitled to receive Maintenance for such Supported Software.
8.3	Warranty for Non-Supported Software. Telcordia's warranty, if any, on
Non-Supported Software will be as set forth in the applicable
Professional Services Work Statement or Professional Services
Attachment.
8.4	Warranty for Services and Deliverables.  Telcordia warrants that the
Services and Deliverables provided under this Agreement will (1)
substantially  conform to the Services and/or Deliverables, as
applicable, as described in the applicable Work Statement(s), and (2)
be performed in a professionally diligent manner by qualified personnel
("Satisfactory Work").
8.5	Correction of Unsatisfactory Work. Telcordia will respond with
qualified personnel to correct any Service or Deliverable, as
applicable, which is not Satisfactory Work, and which has been reported
by CTC in writing within thirty (30) days of CTC's receipt of the
Deliverable from Telcordia or Telcordia's performance of the Service,
as applicable. If, within such thirty (30) day period, CTC does not
provide Telcordia with written notice that a Service or Deliverable is
not Satisfactory Work, such Deliverable and/or Service shall be deemed
