 WHEREAS on October 17, 2007, AT&T Corp. filed a complaint against Vonage Holdings Corp. and Vonage America, Inc. in the United States District Court for the Western District of Wisconsin, Civil Action No. 07-C-0585-C,
alleging infringement of United States Patent No. 6,487,200 B1 (the “AT&T Action”); 
 WHEREAS SBC Internet Services, Inc. and
AT&T Corp. are affiliates of one another and controlled by AT&T Inc., and Vonage America, Inc. is an affiliate of and controlled by Vonage Holdings Corp.; and 
 WHEREAS AT&T Corp. and Vonage Holdings, Corp. (each a “Party”) each desires to settle the two actions for themselves and their affiliates, without admitting any infringement, and on the following
terms: 
 In consideration of the terms and conditions of this Agreement and other good and valuable consideration, the receipt and sufficiency of which are
acknowledged, the parties identified on the Cover Sheet of this Agreement agree as follows: 
  

	1.	DEFINITIONS 

 For the purposes of this Agreement, certain terms have
been defined below and elsewhere in this Agreement to encompass meanings that may differ from, or be in addition to, the normal connotation of the defined word. 
 1.1. “Affiliate” shall mean with respect to a Party, any entity which, directly or indirectly, Controls, is controlled by or is under common Control with such Party. 
 1.2. “AT&T Action” shall have the meaning provided in the second “whereas” clause above. 
 1.3.
“AT&T Litigation Patent” shall mean U.S. Patent No. 6,487,200 B1, and all continuations, continuations-in-part, divisionals, reissues, reexaminations, foreign counterparts, and any patent applications claiming the priority
thereof. 
 1.4. “AT&T Patents” shall mean patents owned by AT&T or one of its Affiliates that issue prior to the end of the Term.

 1.5. “Controls” (including the terms “controlled” and “controlled by”) shall mean either directly or indirectly:
(a) holds more than fifty percent (50%) of the outstanding voting securities of the entity; or (b) if the entity has no outstanding voting securities, has the right to more than fifty percent (50%) of the profits of the entity,
or has the right in the event of dissolution to more than fifty percent (50%) of the assets of the entity; or (c) has the contractual power to designate more than fifty percent (50%) of the directors of a corporation or, in the case
of unincorporated entities, of individuals exercising similar functions; or (d) possesses the power to direct or cause the direction of the management and policies of a legally recognizable entity, whether through the ownership of voting
shares, by contract or otherwise. 
 1.6. “Credit Amount” shall have the meaning provided in Section 4.7. 
 1.7. “Existing AT&T Services” shall mean products, services, features and functions offered or to be offered by AT&T and its Affiliates within eighteen
(18) months after the Effective Date as demonstrable by AT&T with documentary evidence existing as of the Effective Date. 
 1.8. “Existing
Business” shall mean one million dollars ($1,000,000). 
 1.9. “Existing Vonage Services” shall mean products, services, features and
functions offered or to be offered by Vonage and its Affiliates under the Vonage brand within eighteen (18) months after the Effective Date as demonstrable by Vonage with documentary evidence existing as of the Effective Date. Existing Vonage
Services also includes the provision to Vonage customers of: (i) dual-mode VoIP/wireless portable telephone handsets by lease, sale or otherwise; and (ii) features and functions of fixed-mobile convergence equipment owned and operated
by Vonage, solely to the extent required to enable Vonage customers to use dual-mode VoIP/wireless portable telephone handsets to connect to Vonage’s VoIP network. Existing Vonage Services includes the use by Vonage’s customers of wireless
equipment owned by the customer or Vonage, but only to the extent required to enable Vonage’s customers to connect to Vonage’s VoIP network. For example, Vonage’s customers may use cordless telephones, WiFi telephones, wireless access
points, and the Vonage V-Phone only to access Vonage’s VoIP network. Existing Vonage Services do not include any other rights in or to any other Wireless Service or the use thereof. 
  

 1 

 1.10. “Vonage Supplier” shall mean any Vonage supplier of products or services of Existing Vonage Services for
which Vonage has indemnification or warranty/representation obligations pursuant to Section 2.3(a). 
 1.11. “New Business” shall mean, with
respect to a given calendar year, the dollar amount determined by subtracting the Existing Business from combined payments made by Vonage and its Affiliates to AT&T and its Affiliates in that calendar year for the purchase of products and
services furnished by AT&T and its Affiliates in that calendar year under and pursuant to the terms of the AT&T Network Connections Service Agreement to be executed within 180 days of the signing of this Agreement. Such Vonage payments shall
be calculated net of all discounts, and credits and associated taxes and/or surcharges. Should the result of this subtraction be less than zero, then the New Business for the year in question shall be zero. 
 1.12. “Term” shall mean the time period commencing on the Effective Date and ending on the fifth anniversary of the Effective Date. 
 1.13. “Vonage Action” shall have the meaning provided in the first “whereas” clause above. 
 1.14. “Vonage Litigation Patents” shall mean U.S. Pat. Nos. 4,782,485, 5,015,136 and 5,444,707, and all continuations, continuations-in-part, divisionals,

 1.15. “Vonage Patents” shall mean
patents owned by Vonage or one of its Affiliates that issue prior to the end of the Term. 
 1.16. “Wireless Service” shall mean any communication
service based in whole or in part on wireless communication methods, including but not limited to communications using GSM, UMTS, CDMA, cellular, WiFi, WiMax, wireless LANs, wireless packet networks, personal area networks, or personal
communications networks. For the avoidance of doubt with respect to Section 1.9, the term “Wireless Service” does not include any features or functions of fixed-mobile convergence equipment owned and operated by Vonage solely to the
extent required to connect Vonage’s VoIP network to a Wireless Service to enable Vonage customers to connect to Vonage’s VoIP network using dual-mode VoIP/wireless portable telephone handsets provided by Vonage. 
  

	2.	LICENSES AND COVENANTS 

 2.1. License under the AT&T
Litigation Patent. For the Term of the Agreement, conditioned upon Vonage making all payments due pursuant to Section 4.1, AT&T, on behalf of itself and its Affiliates, hereby grants to Vonage and its Affiliates a personal,
royalty-bearing, non-exclusive license under the AT&T Litigation Patent to make, have made, sell, offer for sale, use and import any product or service. 
 2.2. License under the AT&T Patents for the Existing Vonage Business. For the Term of the Agreement, conditioned upon Vonage making all payments due pursuant to Section 4.1, AT&T, on behalf of itself and its Affiliates,
hereby grants Vonage and its Affiliates a personal, royalty-bearing, non-exclusive license under the AT&T Patents: 
  

	 	(a)	to make and use services and products in order to offer Existing Vonage Services under the Vonage or Vonage Affiliate brand to Vonage customers; 

  

	 	(b)	to sell any products made under Section 2.2(a) to Vonage customers under the Vonage or Vonage Affiliate brand, including dual mode VoIP/wireless portable telephone handsets,
for Existing Vonage Services; and 

  

	 	(c)	to sell Existing Vonage Services under the Vonage or Vonage Affiliate brand based on Vonage’s licensed use of services and products under Section 2.2(a).

 Notwithstanding Section 2.2(b) concerning sale of dual mode VoIP/wireless portable telephone handsets, no rights or licenses under
AT&T’s or its Affiliates’ intellectual property are provided to Vonage or its customers to own or operate a wireless network to provide any Wireless Service in conjunction with a dual-mode VoIP/wireless portable telephone handset.

 2.3. Vonage Suppliers. 
  

	 	(a)	 The parties agree that the primary purpose of the license granted to Vonage is to enable Vonage to continue to offer and provide during the Term Vonage Existing
Services without claims of infringement of the AT&T Patents against itself, or against Vonage Suppliers to the extent Vonage: (i) indemnifies them for patent infringement for providing Vonage Existing Services; or (ii) provides
warranties or representations relating to patent infringement to them for providing Vonage Existing Services. In the event AT&T receives written notice from Vonage that Vonage has received an indemnity demand or breach claim related to an
infringement warranty or representation from a Vonage Supplier as a result of a claim by AT&T that such Vonage 

  

 2 

	 	 
Supplier infringed any of the AT&T Litigation Patent or AT&T Patents (which indemnity demand or breach claim Vonage, in its reasonable judgment,
either does not dispute or fails to prevail in a formal dispute (via arbitration or judicial forum) regarding the validity of the indemnity demand or breach claim), AT&T agrees not to seek a license or pursue a lawsuit for relief and/or damages
against such Vonage Supplier, but only to the extent of Vonage’s obligation to the Vonage Supplier with respect to only those products and services provided by such Vonage Supplier to Vonage for use in or support of Vonage’s Existing
Services. AT&T agrees to provide such Vonage Supplier notice of such exclusion for purposes of enabling Vonage to be released from its indemnity obligation or from liability for breach of a representation or warranty. For avoidance of doubt,
nothing herein grants a license to any Vonage Supplier or prevents AT&T from offering licenses to or pursuing infringement claims against Vonage Suppliers with respect to products and services for which Vonage has no indemnification obligation
or liability for breach of a representation or warranty relating to patent infringement. Vonage shall not agree to indemnify or provide any warranty or representation relating to patent infringement to any Vonage Supplier for the sole purpose of
enabling the Vonage Supplier to avoid any infringement claims asserted by AT&T for which the Vonage Supplier otherwise would have been liable prior to the suit being filed by AT&T. For avoidance of doubt, any products or services provided by
Vonage Suppliers that are not used in Existing Vonage Services are not licensed under this Agreement or subject to the terms of this Section 2.3(a). 

 On a confidential basis, in response to a confidential written request from AT&T, who in good faith is considering approaching another company about taking a license to AT&T’s intellectual property,
identifying one or more companies, Vonage shall indicate within thirty days of such request whether any such companies are indemnitees of Vonage, and the parties agree to reasonably cooperate with one another to further clarify or refine the
information requested. Such written requests from AT&T shall be made no more than once per calendar quarter and shall include the subject matter of any potential action and Vonage’s response shall identify the products and services provided
by the potential indemnitee and the volume thereof sufficient to describe the extent of any indemnity owed to such potential indemnitee(s), subject to any existing confidentiality agreements that then may be in place between Vonage and the potential
indemnitee. 
  

	 	(b)	The foregoing license shall extend to and be for the benefit of customers of Vonage to use Existing Vonage Services sold or otherwise provided under Section 2.2(c) with:
(i) products made by Vonage pursuant to Section 2.2(a); or (ii) VoIP products made for Vonage by a Vonage Supplier pursuant to Section 2.3(a). The license granted in Section 2.2 does not otherwise extend to or provide any
right, license or other benefit for any third party other than such Vonage customers to use Existing Vonage Services. 

  

	 	(c)	AT&T is free to assert infringement claims under the AT&T Patents against all third parties except: (i) any supplier of Vonage to the extent it is an Vonage Supplier
providing products or services to Vonage pursuant to Section 2.3(a); or (ii) any customer using Existing Vonage Services with a product or service provided by or for Vonage pursuant to Section 2.2(a) or Section 2.3(b).

 2.4. License under the Vonage Litigation Patents. 
  

	 	(a)	For the Term of the Agreement, Vonage and its Affiliates hereby grant to AT&T and its Affiliates a personal, royalty-free, fully paid-up, irrevocable, non-exclusive license
under the Vonage Litigation Patents to make, have made, sell, offer for sale, use and import any product or service. 

  

	 	(b)	 Notwithstanding Section 2.4(a), nothing contained in this Agreement shall be construed as granting any kind of license rights to, or covenants not to assert
patent infringement claims against, Nortel Networks, Inc. (“Nortel”) under the Vonage Litigation Patents. However, to the extent that AT&T or any of its Affiliates agreed to indemnify Nortel for products and services provided for use
in or support of the AT&T Existing Services, Vonage agrees not to seek a license or pursue a lawsuit for relief and/or damages against Nortel, but only to the extent of AT&T’s or its Affiliate’s obligation to Nortel with respect to
only 

  

 3 

	 	 
those products and services provided by Nortel for use in or support of AT&T’s Existing Services. Vonage agrees to provide Nortel notice of such
exclusion for purposes of enabling AT&T and its Affiliates to be released from their indemnity obligations. AT&T shall not agree to indemnify or provide any warranty or representation relating to patent infringement to Nortel for the
sole purpose of enabling Nortel to avoid any infringement claims asserted by Vonage for which Nortel otherwise would have been liable prior to the suit being filed by Vonage. 

 2.5. License under the Vonage Patents for the Existing AT&T Business. For the Term of the Agreement, Vonage hereby grants AT&T and its Affiliates a
personal, royalty-free, fully-paid up, irrevocable, non-exclusive license under the Vonage Patents: 
  

	 	(a)	to make have made and use services and products in order to offer Existing AT&T Services under the AT&T or AT&T Affiliate brand to AT&T customers;

  

	 	(b)	to sell any products made under Section 2.5(a) to AT&T customers under the AT&T or AT&T Affiliate brand for Existing AT&T Services; and

  

	 	(c)	to sell Existing AT&T Services under the AT&T or AT&T Affiliate brand based on the licensed use of services and products under Section 2.5(a).

 2.6. No Other Rights. Except as expressly set forth in Section 2 of this Agreement, no other rights or licenses under the
intellectual property rights of a Party, including the right to sublicense, are granted or implied. Nothing contained herein shall be construed as conferring by implication, estoppel or otherwise any right or license in favor of a Party in any
patents or other intellectual property rights of the other Party, other than the AT&T Litigation Patent, Vonage Litigation Patents, AT&T Patents and Vonage Patents, as the case may be. 
 2.7. Unauthorized Activities. All rights and licenses provided in this Agreement are subject to the Agreement’s terms and conditions. Without limiting any of
a Party’s rights under this Agreement or at law or in equity, or otherwise expanding the scope of the rights and licenses provided hereunder, if the other Party fails to perform any of its obligations under this Agreement, or exceeds the scope
of the licenses granted to it herein, then the activities, products and services of such other Party shall not be considered licensed or otherwise authorized under this Agreement. 
  

	3.	RELEASES AND SUIT DISMISSAL 

 3.1. Dismissal by AT&T.

  

	 	(a)	AT&T shall dismiss without prejudice the AT&T Action. Concurrent with the execution of this Agreement, through their counsel, the Parties shall execute, and within three
(3) business days thereafter file in the AT&T Action, a Stipulation and Request for Order of Dismissal without prejudice with respect to AT&T’s claims against Vonage in the form attached hereto as Schedule A. Each Party shall bear
its own fees and costs incurred in connection with the AT&T Action. 

  

	 	(b)	AT&T retains the right after termination of this Agreement to re-file the AT&T Action in any proper forum and venue, including in the court in the Western District of
Wisconsin in which it is currently pending (“original forum and venue”), and may reassert in the re-filed action any and all claims arising from activity that is not licensed under this Agreement as a result of such termination, subject to
the rights acquired by Vonage by payments made pursuant to Sec. 4.1. Vonage shall not object to the re-filing of the AT&T Action in any proper forum and venue, and shall not raise any counterclaims or defenses based in any way on this Agreement
with respect to issues of patent validity, enforceability, infringement or the passage of time between the original filing date of the AT&T Action and the re-filing of the action. Vonage is free to assert any and all defenses and counterclaims
relating to issues of patent validity, enforceability and infringement that are not based on this Agreement and Vonage shall have the right to raise any defense or counterclaim based on this Agreement licensing or otherwise authorizing Vonage’s
allegedly infringing activities. In the event that termination occurs prior to the end of the five year term of this Agreement, with respect to any activities that occurred prior to the Effective Date, AT&T may reassert in the re-filed action
any and all claims arising from activity that is not released under this Agreement pursuant to Section 3.3, unless AT&T collects all amounts owing under Section 8.6 “Liquidated Damages” and Section 8.7 “Accelerated
Payment”. 

  

 4 

 3.2. Dismissal by Vonage. Vonage shall dismiss with prejudice the Vonage Action. Concurrent with the execution of
this Agreement, through their counsel, the Parties shall execute, and within three (3) business days thereafter file in the AT&T Action, a Stipulation and Request for Order of Dismissal with prejudice with respect to Vonage’s claims
against AT&T and AT&T’s claims against Vonage in the form attached hereto as Schedule B. Each Party shall bear its own fees and costs incurred in connection with the Vonage Action. 
 3.3. Release by AT&T. Conditioned upon Vonage making all payments due pursuant to Section 4.1, AT&T, on behalf of itself and its Affiliates, owners,
predecessors, successors in interest, divisions, assigns, officers, agents, directors, officers, employees, representatives, attorneys, and all persons acting by, through, under, or in concert with any of them (“AT&T Releasing
Parties”), shall fully release Vonage and its Affiliates, and discharge Vonage and its Affiliates, owners, predecessors, successors in interest, divisions, assigns, officers, agents, directors, officers, employees, representatives and
attorneys, from any and all claims and causes of action, whether known or unknown, arising prior to the Effective Date that the AT&T Releasing Parties have or may have relating to the infringement, contributory infringement or inducement of
infringement of the AT&T Litigation Patent. This release shall include all claims identified in the pleadings of the AT&T Action and all claims relating to the AT&T Litigation Patent that could have been brought in the AT&T Action.
This release shall include a full release of any obligation of Vonage to make any payment pursuant to ¶ 4 of the Agreement dated May 25, 2005 in the Vonage Action between Digital Packet Licensing, Inc. and AT&T Corp. 
 3.4. Release by Vonage. Vonage, on behalf of itself and its Affiliates, owners, predecessors, successors in interest, divisions, assigns, officers, agents,
directors, officers, employees, representatives, attorneys, and all persons acting by, through, under, or in concert with any of them (“Vonage Releasing Parties”), hereby fully releases AT&T and its Affiliates, and discharges AT&T
and its Affiliates, owners, predecessors, successors in interest, divisions, assigns, officers, agents, directors, officers, employees, representatives and attorneys, from any and all claims and causes of action, whether known or unknown, arising
prior to the Effective Date that the Vonage Releasing Parties have or may have relating to the infringement, contributory infringement or inducement of infringement of the Vonage Litigation Patents. This release includes all claims identified in the
pleadings of the Vonage Action and all claims relating to the Vonage Litigation Patents that could have been brought in the Vonage Action. This release shall include a full release of any obligation of AT&T to make any additional payments
pursuant to ¶ 3 of the Agreement dated May 25, 2005 in the Vonage Action between Digital Packet Licensing, Inc. and AT&T Corp. 
  

	4.	PAYMENTS 

 4.1. Payments to AT&T. As partial consideration for the foregoing dismissal, release and licenses to Vonage, Vonage shall pay AT&T six hundred and fifty-thousand dollars ($650,000) in each month during the Term. The first
such payment shall be made by Vonage prior to December 31, 2007 for January of 2008, and payments for each month thereafter shall be made no later than the 10th of the preceding month. 
 As additional consideration for the foregoing dismissal, release and licenses to Vonage, no later
than the end of January 2008, Vonage shall pay to AT&T an amount equal to one million nine hundred fifty thousand dollars ($1,950,000) as prepayment of the last three months of payments due under this Agreement. Beginning in April 2008, the
parties agree to revisit and discuss in good faith options that may be available to provide AT&T with additional assurances regarding the payments to be made by Vonage pursuant to the terms of this Agreement, it being understood that the parties
may ultimately decide that mutually acceptable additional assurances do not exist. 
 4.2. Method of Payment. 
  

	 	(a)	All payments required hereunder shall be paid to AT&T by electronic bank transfer to the following account: 

  

					
		 	Bank:	  	JP Morgan Chase

 Attn: Dave Haug 
 Tel: (512) 372-5173 
 Fax: (512) 241-6994 
 AT&T may change the foregoing payment account and address upon written notice to Vonage. 
 4.3. Overdue Payments.
If Vonage fails or refuses to make any payment hereunder on or before the date on which such payment is due, Vonage shall pay AT&T, at such time such payment is actually made, a fee equal to one and a half percent (1.5%) of the amount of
such payment for each month, or fraction of a month, that such payment is overdue, but in no event shall the amount of such fee exceed the maximum permitted by law. 
 4.4. Currency. All payments to be made under this Agreement shall be made in United States dollars, in immediately available funds and not in stock, bankruptcy claims or any other medium. For the avoidance of
doubt, allowance of a bankruptcy claim shall not be deemed a payment. Any conversion to United States dollars for a payment required under this Agreement shall be at the prevailing rate for bank cable transfers as quoted for the day such payment is
due under this Agreement or, if paid earlier, the day actually paid, by leading United States banks in New York City dealing in the foreign exchange market. 
 4.5. Taxes. Vonage shall bear all taxes, duties, levies and other similar charges (and any related interest and penalties), however designated (hereinafter, “governmental charges”), imposed as a result of the existence or
operation of this Agreement, including any tax which Vonage is required to withhold or deduct from payments to AT&T, except (a) any tax imposed upon AT&T in a jurisdiction outside the United States if and only to the extent such tax is
allowable as a credit against the United States income taxes of AT&T, and (b) any net income tax imposed upon AT&T by the United States or any governmental entity within the United States proper (the fifty (50) states and the
District of Columbia). In order for the exception contained in (a) to apply, Vonage must reduce such tax to the extent possible giving effect to the applicable Income Tax Convention between the United States and Vonage’s country of
incorporation, and furnish AT&T with such evidence as may be required by United States taxing authorities to establish that such tax has been paid so that AT&T may claim the credit. If Vonage is required to bear any governmental charges
pursuant to this paragraph, then Vonage shall pay any additional taxes, charges and amounts as are necessary to ensure that the net amounts received by AT&T after all such governmental charges are made are equal to the amounts which AT&T is
otherwise entitled under this Agreement as if such governmental charges did not exist. 
 4.6. Other Costs. Each Party will be responsible for the
costs it incurs in carrying out its obligations under this Agreement. 
 4.7. Business Credit. Vonage shall have a personal and non-transferable
(notwithstanding Section 9.10) option to reduce the payment(s) that becomes due during the months following the third year of the Term pursuant to Section 4.1 through the application of a “Credit Amount” earned by Vonage as a
result of New Business. Although, by definition, New Business is limited to services and products purchased under and pursuant to the terms of the AT&T Network Connections Service Agreement to be executed within 180 days of the signing of this
Settlement Agreement, Vonage and AT&T may agree to include other service agreements as New Business (“Additional Business”) but AT&T is not obligated to consider Additional Business or to include Additional Business on the same
formula as the Credit Amount defined herein. A Credit Amount reduces the required payment on a dollar for dollar basis. The Credit Amount shall be calculated as follows: For each calendar year, the Credit Amount shall be 10% of the New Business.

 The following examples illustrate how the Credit Amounts will be calculated and applied. 
  

	 	(a)	If New Business from Vonage and its Affiliates in the calendar year 2008 totals $1,000,000, the Credit Amount would be $100,000 (10% of $1,000,000). This Credit Amount would be
applied to reduce the outstanding monthly payments beginning in the first month following the third year of the Term o. The $650,000 payment due in January 2011 would be reduced from $650,000 to $550,000. 

  

	 	(b)	Then, if the New Business from Vonage and its Affiliates in calendar year 2009 totals $2,000,000, the Credit Amount for that year would be $200,000 (10% of $2,000,000). This Credit
Amount would be applied to reduce the outstanding monthly payments beginning in January 2011. The $550,000 payment due in January 2011 (resulting from the reduction applied in Section 4.7(a)) would be reduced from $550,000 to $350,000.

 For Vonage to exercise this option, it shall provide to AT&T within ninety (90) days of the close of each calendar year during the
Term sufficient documentation to establish the amount of New Business made in that calendar year. Vonage agrees to allow AT&T, pursuant to non-use and 

  

 6 

 
non-disclosure obligations between the Parties, to share with its Affiliates any such New Business documentation that Vonage elects to provide to AT&T,
and permit AT&T and its Affiliates to use any such information for the purpose of addressing matters regarding the Credit Amount. Within ninety (90) days of receipt of such documentation, AT&T will provide Vonage with a written
statement specifying the Credit Amount associated with that calendar year, the payment month of the Term to which the Credit Amount will be applied, and the revised amount due under Section 4.1 for that month. 
 No payments are owed by AT&T or its Affiliates to Vonage or its Affiliates under this Agreement. This Agreement does not reflect an obligation on the part of Vonage
or its Affiliates to continue doing business with AT&T or its Affiliates or to increase such business. Vonage acknowledges that discontinuation of such business will not relieve Vonage of the obligation to make the payments set forth in
Section 4.1, provided however that such payments may be reduced by any Credit Amount earned but unapplied at the time of such discontinuation. This Agreement does not obligate AT&T or its Affiliates to provide products or services to Vonage
or its Affiliates. 
 4.8 Payment Obligations. Vonage’s obligation to pay all amounts hereunder shall be absolute and unconditional and shall not
be affected by any circumstance whatsoever, including: (a) any set-off (except by the Credit Amount pursuant to Section 4.7), counterclaim, recoupment, defense or other right which Vonage may have against AT&T; (b) any insolvency,
bankruptcy, reorganization or similar proceedings by or against Vonage or AT&T; or (c) any other circumstances, whether or not unforeseen or similar to any of the foregoing. 
  

	5.	PUBLICITY 

 5.1. No Use of Marks. Neither Party nor its
Affiliates shall, in any manner, reference the other Party, its trade names, trademarks, service marks or any other indicia of origin, or indicate that its products or services are in any way sponsored, approved or endorsed by the other Party.

 5.2. Public Disclosures. Neither Party shall make any public disclosures inconsistent with the rights and obligations created hereunder. Either
Party may require the other Party to promptly supply a copy of any public disclosure which the other Party made related to this Agreement. Both Parties shall be entitled to issue a press release relating to the subject matter of this Agreement, the
contents of which shall be subject to prior approval of both Parties, which shall not be unreasonably withheld. Nothing in this Section prevents either Party from making public disclosures without prior approval of the other Party to the extent
required, on the advice of counsel, by federal and state laws. 
  

	6.	CONFIDENTIALITY 

 6.1. Except for the information contained in the
press release permitted under Section 5.2, the Parties agree that they shall not disclose the contents of this Agreement, or information or records disclosing in any way the content of their negotiations, to anyone unless such disclosure is:
(i) lawfully required by any governmental agency; (ii) otherwise required to be disclosed by law including legally required financial reporting; or (iii) necessary in any legal proceeding in order to enforce any provision of this
Agreement; or (iv) to their auditors, accountants, tax and financial advisors, and/or legal counsel only to the extent required for professional advice from those sources, or to the actual or prospective purchasers of all or a portion of the
assets of AT&T or Vonage, for the purposes of due diligence, but only after the Party seeking to make the disclosure secures a written commitment from such persons to maintain the confidentiality of the terms of this Agreement to the extent
possible considering the purpose for which the terms of the Agreement are needed by the auditors, accountants, tax and financial advisors, legal counsel and purchasers. 
 6.2. Section 6.1 does not apply where a Party, on the advice of counsel, must comply with applicable law or other demand under lawful process, including a discovery request in a civil litigation or from a
governmental agency or official, if the Party first notifies all other Parties of the required disclosure in writing within five (5) business days of the receipt of any subpoena, court order, or administrative order requiring disclosure of
information subject to the nondisclosure provisions of Section 6.1, and cooperates with the other Parties, at the other Parties’ expense, in seeking reasonable protective arrangements with the third party requiring disclosure under
applicable law or other demand under lawful process. In no event shall a Party’s cooperation hereunder require the Party to take any action which, on the advice of that Party’s counsel, could result in the imposition of any sanctions or
other penalties against the Party. 
 6.3. Survival. Notwithstanding the expiration or termination of this Agreement, all of the confidentiality
obligations pursuant to this Agreement shall survive expiration or termination with respect to any information received prior to such expiration or termination.

that execution, delivery and performance of this Agreement does not and will not violate any provision of any order, writ, judgment or decree of any court or governmental authority to which any of the Parties is bound.

implied, or assumes any responsibilities whatever with respect to use, sale, or other disposition by the other Party or the other Party’s customers of products incorporating or made by use of: (i) inventions licensed under

	8.	TERM AND TERMINATION 

 8.1. Term. This Agreement shall be
effective during the Term unless sooner terminated in accordance with this Agreement. 
 8.2. Early Termination - Either Party. Either Party may
terminate this Agreement: 
  

	 	(a)	in accordance with any terms of this Agreement which expressly provide for such Party to terminate this Agreement; or 

  

	 	(b)	upon thirty (30) days prior written notice, if the other Party has breached its material obligations under this Agreement and such breach remains uncured during such thirty
(30) day period. 

 8.3. Early Termination by AT&T. AT&T may terminate this Agreement or any of the license rights granted
to Vonage herein immediately: (a) if Vonage brings a suit against AT&T or any of its Affiliates in relation to patents owned or controlled by Vonage or its Affiliates or the AT&T patents licensed hereunder unless such suit is in
response to a lawsuit brought by AT&T or its Affiliates against Vonage or its Affiliates; (b) if Vonage is liquidated, dissolved, or adjudged to be in a state of receivership; (c) if Vonage makes a general assignment or general
arrangement to or for the benefit of its creditors, or to a receiver or trustee in bankruptcy; (d) upon the filing by or against Vonage of a petition for bankruptcy, except as set forth in the exception below; (e) upon the appointment of a
trustee, examiner or receiver to take possession of substantially all of Vonage’s assets or of Vonage’s interests in this Agreement; (f) upon the enforcement by a secured party, attachment, execution, foreclosure or other judicial or
non-judicial seizure of Vonage or substantially all of Vonage’s right, title, and interests under this Agreement; or (g) upon Vonage’s dissolution or ceasing to do business. 
 Exception to AT&T’s early termination ability under section 8.3: If Vonage files a voluntary bankruptcy proceeding solely to restructure its capital structure
based on a business plan shared with AT&T reasonably prior to the filing (and which does not involve the transfer of the Agreement or Vonage’s interests and license rights thereunder to any third party), AT&T shall forebear from
terminating this Agreement under section 8.3 for a period of one hundred eighty (180) days. Thereafter, AT&T may, in its sole discretion based upon the progress of the bankruptcy proceeding, continue to forebear from termination under
section 8.3. 
 8.4. Effect of Termination. Upon termination of this Agreement: 
  

	 	(a)	By AT&T pursuant to Section 8.2 or 8.3, all rights and obligations of the Parties (including the licenses granted to Vonage under Article 2) except the rights granted to
AT&T and obligations due to AT&T, including those under Article 2, Section 3.1(b), Section 8.6, and Section 8.7, shall terminate, except that the rights and obligations of the Parties under this Agreement which expressly or by
their nature would continue beyond the termination of this Agreement shall remain in effect and survive termination of this Agreement, including the Sections pertaining to “CONFIDENTIALITY”, “PUBLICITY”, and “RISK
ALLOCATION”; 

  

	 	(b)	by Vonage pursuant to Section 8.2, all rights and obligations of the Parties (including the licenses granted to AT&T under Article 2) except the rights granted to Vonage
and obligations due to Vonage, including those under Article 2 and Section 4.7, shall terminate, except that the rights and obligations of the Parties under this Agreement which expressly or by their nature would continue beyond the termination
of this Agreement shall remain in effect and survive termination of this Agreement shall remain in effect and survive termination of this Agreement, including Vonage’s obligation to make payments under Article 4 and the Sections pertaining to
“CONFIDENTIALITY”, “PUBLICITY”, and “RISK ALLOCATION”; and 

  

	 	(c)	notwithstanding such specific termination rights, each Party reserves all of its other legal rights and equitable remedies, including the right to sue for breach of contract in any
proper forum and venue. 

 8.5. Extension of Licenses. Except termination pursuant to Section 8.2 and 8.3, following termination of
this Agreement, either Party may request an extension or license of a patent licensed under this Agreement, and the other Party agrees to offer such extension or license at commercially 

  

 9 

 
reasonable terms substantially the same as those then being offered to similarly situated companies. 
 8.6. Liquidated Damages. In the event that Vonage violates the terms of this Agreement or otherwise defaults under this Agreement, including for non-payment
pursuant to Section 4.1, and such default provides a basis for termination by AT&T under Section 8.2, the parties acknowledge and agree that the amount of actual damages sustained by AT&T would be extremely difficult to ascertain.
Accordingly, as liquidated damages and not as a penalty, Vonage agrees to pay AT&T an amount that results from the multiplication of two hundred and twenty-six thousand, six hundred and sixty-six dollars ($226,666) by the number of months in the
Term for which Vonage did not pay $650,000 pursuant to Section 4.1, the number of months to be further reduced by three months provided Vonage has made the prepayment set forth in Section 4.1, and the Parties agree that such amount
constitutes a reasonable provision for liquidated damages and that such damages could not otherwise be calculated. 
 8.7. Accelerated Monthly
Payments. In the event this Agreement is terminated under Section 8.3, Vonage agrees to pay AT&T an amount that results from the multiplication of two hundred and twenty-six thousand, six hundred and sixty-six dollars ($226,666) by the
number of months in the Term for which Vonage did not pay $650,000 pursuant to Section 4.1, the number of months to be further reduced by three months provided Vonage has made the prepayment set forth in Section 4.1. 
  

	9.	GENERAL TERMS

obligations or to make any representations, warranties or commitments on behalf of the other Party, whether express or implied, or to bind the other Party in any respect whatsoever. Nothing in this Agreement shall be construed as forming any
partnership, joint venture, agency, employment, franchise, distributorship, dealership or other similar or special relationship between the Parties. 
 9.2.
Rules of Construction. As used in this Agreement, (a) 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; (b) 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; (c) the words “Party” and “Parties” refer, respectively, to a party or to both of the parties to this Agreement; (d) 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;
(e) 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; and (f) explicit references to a particular
Section hereof shall be deemed to include a reference to the subsections, if any, associated with the Section as well. This Agreement shall be fairly interpreted in accordance with its terms and without any strict construction in favor of or against
either Party. 
 9.3. Computation of Time. If a time period provided in this Agreement requires a certain action be performed within ten (10) or
less days, then intervening Saturdays, Sundays and legal holidays shall not be included in the computation of time. If a time period requires a certain action be performed within eleven (11) or more days, then intervening Saturdays, Sundays and

 9.5. Dispute Resolution. Any and all controversies or claims of any nature arising out of 

  

 10 

 
or relating to this Agreement or the breach, termination or validity thereof, whether based on contract, tort, statute, fraud, misrepresentation or any other
legal or equitable theory (the “Claim”) shall be resolved solely and exclusively by binding arbitration administered by the American Arbitration Association (“AAA”) pursuant to its Commercial Arbitration Rules then in effect. The
place of arbitration shall be New York City. Any action or preceding collateral to the arbitration, including with limitation to compel or stay arbitration, shall be filed in the federal or state courts located in New York County, New York, and the
Parties agree to the personal jurisdiction and venue of such courts for such purposes. The language of the arbitration shall be in English. The arbitration shall be conducted by one (1) neutral arbitrator. The Parties shall mutually agree to
the nomination of the arbitrator or any replacements thereof, within fifteen (15) days of the commencement of the arbitration or the occurrence of the vacancy as the case may be. If the Parties fail to agree to the arbitrator within the
permitted period, the arbitrator shall be appointed by the AAA using a list procedure. The arbitrator shall not have the power to act as amiable compositeur or ex aequo et bono, or to limit, expand or otherwise modify the terms of the
Agreement. The arbitrator shall not have the power to award punitive, exemplary or any damages other than actual compensatory damages requested by the prevailing Party. Each Party shall bear its own expenses (including without limitation
attorneys’ fees), but the fees of the arbitrator and AAA shall be borne equally by both Parties. Judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. 
 The arbitrator shall strictly limit document discovery to the production of documents directly relevant to the facts alleged in the Parties’ claims, counterclaims
and defenses and, if depositions are required, the arbitrator shall limit each Party to three (3) depositions of no longer than three (3) hours each. The arbitrator shall issue a protective order prohibiting the Parties and any other
participants to the arbitration from disclosing, and the Parties hereto agree not to disclose, to any third party any information relating to the arbitration proceedings or any information obtained via the arbitration, or related discovery,
including documents, evidence, testimony and the award, except as may be required by law or court order. All requests for injunctive relief shall be decided by the arbitrator, provided, however, that requests for temporary or preliminary injunctive
relief may be submitted to the court identified in Section 9.7 if the arbitrator has not yet been appointed. 
 9.6. Patent Issues.
Notwithstanding (i) anything in Section 9.5 to the contrary, and (ii) the Parties’ expectation that Claims, if any, will arise out of or relate to the terms of this Agreement, and will not concern the validity, scope,
enforceability or infringement of the patents licensed hereunder, any claims or counterclaims, including defenses thereto, which potentially concern the validity, scope, enforceability or infringement of any patent shall not be resolved by
arbitration and instead must be resolved before in the United States District Court for the Western District of Wisconsin. 
 9.7. Applicable Law and
Venue. This Agreement shall be governed by and construed in accordance with the laws of the State of New York without regard to its conflicts of law rules. Any judicial suit or action relating to any Claim or counterclaims, except with regard to
Claims covered under Section 9.6, shall be brought and prosecuted only in the U.S. District Court Southern District of New York when standing permits, and otherwise in New York City, New York, and each Party shall submit to and not challenge
venue and personal jurisdiction in such forum with respect to such Claims or counterclaims. 
 9.8. Equitable Remedies. The Parties recognize that
money damages may not be an adequate remedy for any breach or threatened breach of any obligation hereunder by Licensee involving intellectual property or Licensee exceeding the scope of its license. The Parties therefore agree that in addition to
any other remedies available under this Agreement, by law or otherwise, either Party shall be entitled to obtain injunctive relief against any such continued breach by the other Party of such obligations. 
 9.9. Third Party Beneficiaries. Except as provided in Sections 2.3, this Agreement is not intended to be for the benefit of any third party. Notwithstanding the
foregoing, this Agreement shall not be enforceable by any third party, and is not intended to confer on any third party any rights (including third-party beneficiary rights), remedies, obligations or liabilities under or by reason of this Agreement.
This Agreement shall not provide third parties with any remedy, claim, liability, reimbursement, cause of action or other right in excess of those existing without reference to the terms of this Agreement. No third party shall have any right,
independent of any right that exists irrespective of this Agreement, to bring any suit at law or equity for any matter governed by or subject to the provisions of this Agreement. 
 9.10. Change of Control. Except under those circumstances described under Sections 8.3(b) through 8.3(g), if, after the Effective Date, a person or entity acquires AT&T or Vonage and the 

  

 11 

 
acquired Party continues to exist as a separate legal entity, this Agreement shall remain in effect and the acquired Party shall continue to retain the
benefits and obligations of the licenses, covenants and releases set forth herein, as the case may be, but only to the extent the assets of the acquired Party are being used for no more than the number of end user customers of the acquired Party
existing immediately prior to the acquisition date, adjusted annually thereafter at a per annum rate equivalent to the rolling 12 month average per annum growth rate existing immediately prior to the acquisition date, but in no event less than 0%
growth rate. Except under those circumstances described under Sections 8.3(b) through 8.3(g), if, after the Effective Date, a person or entity acquires AT&T or Vonage and the acquired Party does not continue to exist as a separate legal entity,
or a person or entity acquires the business activities of a Party covered under the licenses, covenants and releases set forth herein, this Agreement shall continue in full force and effect and the acquirer shall succeed to the rights and
obligations of the acquired Party or the Party previously owning the covered business, as the case may be, but only to the extent the acquired assets are being used for no more than the number of end user customers of the acquired Party or business,
respectively, existing immediately prior to the acquisition date, adjusted annually thereafter at a per annum rate equivalent to the rolling 12 month average per annum growth rate immediately prior to the acquisition date, but in no event less than
0% growth rate. 
 The foregoing change of control provisions are conditioned upon the Party involved in the acquisition notifying the other Party in writing
of such an acquisition event within sixty (60) days of it occurring and ensuring that the acquirer negotiates with the other Party in good faith within a period of twelve (12) months following the acquisition in order to provide payment
for and receive any licenses, covenants or releases under the patents owned and licensed by the other Party hereunder for those end user customers in excess of the number of end user customers not otherwise covered by a license pursuant to this
Agreement. 
 9.11. Force Majeure. Fire, flood, explosion, war, terrorism, strike, embargo, government requirement, civil or military authority, act
of God, or other similar causes beyond a Party’s control and without the fault or negligence of a Party shall neither excuse a breach of an obligation under this Agreement nor waive the non-breaching Party’s right to terminate this
Agreement for breach hereof. 
 9.12. Assertion of Unenforceability. In the event that any provision of this Agreement is deemed illegal or
unenforceable, this Agreement shall terminate unless both Parties are able to arrive at an accommodation that preserves for the Parties the benefits and obligations of the offending provision. Both Parties agree to use their reasonable efforts to
arrive at such an accommodation. 
 9.13. Assignment. Except under those circumstances described under Sections 9.10, the Parties hereto have entered
this Agreement in contemplation of personal performance by each Party and intend that the rights and licenses granted to a Party hereunder not extend to other entities without the other Party’s express written consent. Accordingly, neither this
Agreement nor any of a Party’s rights or obligations hereunder, except under those circumstances described under Section 9.10, shall be assigned, sublicensed, or transferred (in insolvency proceedings, by mergers, acquisitions or
otherwise) by the Party without such consent of the other Party. Any assignment or other transfer which is inconsistent with the foregoing shall be null and void ab initio. 
 9.14. Entire Agreement; No Modification or Waiver. This Agreement constitutes the entire agreement between the Parties concerning its subject matter and supersedes all prior written or oral negotiations,
correspondence, understandings and agreements between the Parties respecting such subject matter. This Agreement shall not be modified or rescinded, except by a writing signed by both Parties. No provision of this Agreement shall be deemed modified
by any action or omission or failure to object to any action which may be inconsistent with the terms of this Agreement. No waiver of a breach committed by a Party in one instance shall constitute a waiver or license to commit or continue breaches
in other or like instances. By way of example only and without limiting the foregoing, this Agreement may not be modified by any statement appearing on any check or similar transfer of money, or by any provision appearing in any preprinted form of
one Party unless expressly accepted by the other Party in a writing which expressly refers to such preprinted form and this Agreement. 
 9.15.
Counterparts. The Parties may execute two (2) copies of this Agreement, each of which shall constitute an original copy of this Agreement. A scanned, imaged, facsimile or photocopy of this Agreement as executed by the Parties shall be
deemed to be an original executed copy for all purposes.

dismissing without prejudice all claims and counterclaims in the Texas and Delaware Litigations in the forms set forth in Exhibits C and D, respectively. Vonage agrees to dismiss without prejudice Central Telephone Company of Texas from the Texas
Litigation. 
 2.2 The Parties agree that they shall bear their own costs, expenses and attorneys’ fees relating to the Texas and
Delaware Litigations, and to the negotiation of this Agreement. 
 ARTICLE 3 LICENSES 
 3.1 Vonage on behalf of itself and its Affiliates as of the Effective Date grants to Nortel and its Affiliates a worldwide, non-exclusive, paid-up,
transferable (but only as provided in Section 6.4) license under the Vonage Patents solely to develop, make, have made, use, market, offer for sale, sell, lease, distribute, import and export Nortel Products. Vonage grants Nortel the limited
right to grant sublicenses to its customers (hereinafter, “Licensed Customer”) to use, market, offer for sale, sell, lease, distribute, import and export the Nortel Products, but only when such products are sold or manufactured by or for
Nortel. Sublicenses to customers 

  

 2 

 
shall be deemed to exist solely by virtue of such customers use, marketing, offer for sale, sale, lease, distribution, importation and/or exportation of the
Nortel Products without need for any additional action or documentation of any kind. 
 3.2 Nortel on behalf of itself and its Affiliates as
of the Effective Date grants to Vonage and its Affiliates a worldwide, non-exclusive, paid-up, transferable (but only as provided in Section 6.4) license under the Nortel Patents solely to develop, make, have made, use, market, offer for sale,
sell, lease, distribute, import and export Vonage Products. Nortel grants Vonage the limited right to grant sublicenses to its customers (hereinafter, “Licensed Customer”) to use, market, offer for sale, sell, lease, distribute, import and
export the Vonage Products, but only when such products are sold or manufactured by or for Vonage. Sublicenses to customers shall be deemed to exist solely by virtue of such customers use, marketing, offer for sale, sale, lease, distribution,
importation and/or exportation of the Vonage Products without need for any additional action or documentation of any kind. 
 3.3 Vonage
covenants not to sue customers of Nortel or its Affiliates for patent infringement of the Vonage Patents by reason of a Nortel customer’s licensed use of the Nortel Products, and Vonage will not seek any damages or costs during the term of the
license in section 3.1 or prior to the Effective Date from Nortel customers for such use; provided, however, such covenants will become ineffective, null and void should Nortel bring a patent infringement suit against Vonage or against a Vonage
customer with respect to any patent, prior to Vonage bringing any such suit against Nortel. 
 3.4 Vonage releases Central Telephone Company
of Texas and its customers on the Effective Date from all claims, demands and rights of action which Vonage or its Affiliates may have on account of any act of infringement or alleged infringement of any of the Vonage Patents by Central Telephone
Company of Texas or its customers prior to the Effective Date. 
 3.5 Either Party may terminate the licenses granted in sections 3.1 and 3.2
if the other Party (a) brings a patent infringement suit against that Party with respect to patents not licensed hereunder or (b) brings a patent infringement suit against a Third Party under any patents which Third Party asserts a good
faith claim of indemnification against either of Vonage or Nortel or any of their Affiliates. In such an event, neither Party shall be able to seek and obtain damages for patent infringement for activities validity licensed under sections 3.1 and
3.2 during the licensed period from the Effective Date until the date of license termination under this Agreement. 
 3.6 If any of the
Vonage or Nortel Patents are assigned or transferred, or if the right to enforce the patent(s) is otherwise conveyed, to an entity not an Affiliate of such Party in a transaction that is not part of a Change of Control, the assignment, transfer or
other conveyance of rights shall not include the right to assert against the other Party, its Affiliates, or its customers any claims of infringement under any of the Vonage or Nortel Patents, as the case may be, that arose prior to the Effective
Date. With respect to any claims of infringement under any of the Vonage or Nortel Patents, as the case may be, arising after the Effective Date, such claims will be precluded to the extent released or licensed in the remainder of section 3 and the
parties hereby confirm that any assignment, transfer, or conveyance made under this section 3.6 is made 

  

 3 

 
subject to any licenses, sublicenses, covenants not to sue, and releases granted in sections 3.1, 3.2, 3.3, 3.4, and 3.7. 
 3.7 Nortel hereby covenants not to sue suppliers of products or services to Vonage (hereinafter, “Vonage Supplier”), during the term of any
Nortel Patent, for infringement of any Nortel Patent to the extent Vonage indemnifies them for patent infringement for providing products or services to Vonage. For the avoidance of doubt, nothing herein grants a license to any Vonage Supplier or
prevents Nortel from offering licenses to or pursuing infringement claims against Vonage Suppliers with respect to products and services provided to persons other than Vonage or for which Vonage has no indemnification obligation. Vonage shall not
agree to indemnify relating to patent infringement to any Vonage Supplier for the sole purpose of enabling the Vonage Supplier to avoid infringement claims asserted by Nortel for which the Vonage Supplier would otherwise have been liable prior to
this litigation. The covenants contained in this section 3.7 will become ineffective, null and void should Vonage bring a patent infringement suit against Nortel or against a Nortel customer with respect to any patent, prior to Nortel bringing any
such suit against Vonage. 
 ARTICLE 4 TERMINATION 
 4.1 Term. The term of this Agreement shall commence upon the Effective Date and, unless terminated as permitted pursuant to this Article 4, shall continue until the expiration of the last-to-expire of the
Vonage Patents and the Nortel Patents. 
 4.2 Material Breach. Either Party may terminate this Agreement upon a material breach by the
other Party; provided the other Party shall have thirty (30) days from the date of notice of breach to cure such breach. 
 4.3
Effect of Termination. In the event of termination of this Agreement, the licenses and covenants in Article 3 shall immediately terminate and be of no force and effect going forward. 
 ARTICLE 5 INDEMNIFICATION 
 5.1 Each Party (“Indemnifying Party”)
agrees to indemnify, defend and hold harmless the other Party, and its Affiliates and their respective employees, principals (partners, shareholders or other holders of an ownership interest, as the case may be), current or former directors,
officers, agents and assignors and their respective successors, heirs and assigns (collectively, the “Indemnified Party”) from and against any and all losses, damages, attorneys fees or costs arising from an indemnification claim brought
in good faith by a Licensed Customer of the Indemnified Party which results from any claims brought by an Indemnifying Party that any use of a product or service by the Licensed Customer infringes any of the Indemnifying Party’s patents
licensed under this Agreement (i.e., either one of the Nortel Patents or Vonage Patents, depending on the Party). Under no circumstances shall an Indemnifying Party have such an obligation to indemnify the other Party if the Party seeking
indemnification brought a patent infringement suit (after the Effective Date) against the Party from which 

  

 4 

 
indemnification is sought prior to the initiation of the suit resulting in the indemnification claim by the Licensed Customer. 
 5.2 In the event of a claim for which an Indemnified Party will seek indemnity or reimbursement under section 5.1, such Party shall notify the
Indemnifying Party in writing as soon as practicable, but in no event later than thirty (30) days after receipt of such claim from Licensed Customer, together with such further information as is necessary for the Indemnifying Party to evaluate
such claim to the extent that the Indemnified Party is in possession or has knowledge of such information. 
 ARTICLE 6 GENERAL

 6.1 Representations and Warranties.

enforceable, and (iii) it has not assigned or otherwise transferred to any other Third Party any rights to enforce any of the Nortel Patents.

intellectual property rights, except for the licenses expressly granted pursuant to this agreement. 
 6.2 Counterparts. This
Agreement may be executed in counterparts or duplicate originals, both of which shall be regarded as one and the same instrument, and which shall be the official and governing version in the interpretation of this Agreement. This Agreement may be

the existence of applicable sublicenses or covenants pursuant to section 3 and may share the provisions of this Agreement with potential acquirers or merger partners to the extent necessary for necessary due diligence related to contemplated
transactions.

Party making the Assignment to the other Party.

interpretation of this Agreement.

partnership or shall constitute either Party hereto acting as the agent of the other Party for any purpose or in any sense whatsoever.
