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.

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 reimburse Telcordia for all reasonable, documented, out-of-pocket 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 Newark, New Jersey 07102 ABA No. 031201467 For Account of Telcordia Technologies, Inc. Account No. 2018900066914 Attention: Account Officer Telcordia Technologies, Inc., or 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 accepted by CTC. 8.6	Right to Provide Information. CTC represents and warrants to Telcordia that, to the best of its knowledge and subject to Telcordia's compliance with any confidentiality requirements in this Agreement or any other written agreement between the Parties, it has the right to provide the information, specifications and data, including the information, specifications and data of any Third Party, that it has or will provide to Telcordia in order for Telcordia to complete the Services and Maintenance and to create the Deliverables identified hereunder. CTC further represents and warrants that, to the best of its knowledge and subject to Telcordia's compliance with any confidentiality requirements, possession and use of that information, specifications and data by Telcordia under the terms and conditions of this Agreement or any other written agreement between the Parties will not constitute an infringement upon any patent, copyright, trade secret, or other intellectual property right of any Third Party. 8.7 	Warranty of Non-Infringement Telcordia warrants that Supported Software licensed to CTC under a Work Statement does not infringe any United States patent or United States copyright of a Third Party and that a Deliverable under a Professional Services Attachment does not infringe any United States copyright of a Third Party. CTC's sole and exclusive remedy for any actual or alleged breach of this warranty shall be as provided in Section 11 of this Agreement. 8.8 	Disclaimer of Warranties a)	Except as expressly provided in Sections 8.1 through 8.5 and 8.7, Telcordia makes no representations and extends no warranties of any kind with respect to the Licensed Software, Services, Deliverables or Maintenance. By way of illustration and not limitation: i)	Telcordia assumes no responsibility or liability with respect to (i) the use or sufficiency of the Licensed Software, or (ii) any Services or Maintenance furnished with respect to it, and ii)		Telcordia does not warrant that the operation of the Licensed Software will be uninterrupted or error free. b)	The warranties set forth in this Section 8 hereof will not be applied in the event the Licensed Software is used by CTC contrary to its corresponding use specifications and technical requirements set forth in the user and technical handbooks, Documentation and any other documents, including Work Statements and Professional Services Attachments, delivered to CTC by Telcordia. c) 	UNLESS SPECIFICALLY DESCRIBED IN A WORK STATEMENT UNDER THIS AGREEMENT (AND SEPARATELY IDENTIFIED AS "YEAR 2000 SERVICES OR RESULTS"), TELCORDIA'S SERVICES AND THE DELIVERABLES WILL NOT INCLUDE ANY YEAR 2000 ANALYSES, ASSESSMENT, REMEDIATION, TESTING OR OTHER SERVICES OR DELIVERABLES RELATED TO THE YEAR 2000 COMPUTER PROBLEM NOR DOES TELCORDIA MAKE ANY REPRESENTATION OR WARRANTY THAT THE SERVICES OR DELIVERABLES, IF ANY, PROVIDED HEREUNDER WILL NECESSARILY RESULT IN YEAR 2000 COMPLIANCE, READINESS OR FUNCTIONALITY OF ANY OF CTC'S NETWORK, SYSTEMS, HARDWARE, SOFTWARE, MIDDLEWARE OR EMBEDDED SYSTEMS, THE ISSUE OF SUCH COMPLIANCE, READINESS OR FUNCTIONALITY BEING OUTSIDE THE SCOPE OF THIS AGREEMENT UNLESS SPECIFICALLY PROVIDED, AS NOTED ABOVE, IN AN ATTACHED WORK STATEMENT. d)	THE FOREGOING WARRANTIES ARE IN LIEU OF ALL OTHER WARRANTIES, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR ANY PARTICULAR PURPOSE, EVEN IF TELCORDIA HAS BEEN MADE AWARE OF SUCH PURPOSE, AND ANY WARRANTY AGAINST INFRINGEMENT OF PATENTS OR OTHER INTELLECTUAL PROPERTY RIGHTS.
