 Supplier shall be responsible for Supplier’s own labor relations with any labor organization either representing or seeking to represent Supplier’s employees
and shall negotiate and seek to adjust all disputes between Supplier and Supplier’s employees or any union representing Supplier’s employees. Except as otherwise provided in this clause, and subject to the terms of this Agreement, Supplier

Company. 
  
 10.14 Mediation 
  
 If a dispute arises out of or relates to this Agreement, or its breach, and the parties have
not been successful in resolving such dispute through negotiation, the parties agree to attempt to resolve the dispute through mediation by submitting the dispute to a sole mediator selected by the parties or, at any time at the option of a party,
to mediation by the American Arbitration Association (“AAA”). If not thus resolved, it shall be referred to a sole arbitrator selected by the parties within thirty days of the mediation or, in the absence of such selection, to final and
binding arbitration by a sole arbitrator under the AAA Arbitration Rules (“Rules”) in effect on the date of this Agreement. The mediation and arbitration, including arguments and briefs, shall be in the English language in New York City,
New York, United States of America. The arbitrator may not limit, expand or otherwise modify the terms of this Agreement or award exemplary or punitive damages or attorney’s fees. The arbitrator shall apply the substantive (not the conflicts)
law of the state specified in the choice of law provision set forth elsewhere in this Agreement. The award shall be in United States dollars. Judgment upon the award rendered in the arbitration may be entered in any court having jurisdiction
thereof. Each party shall bear its own expenses (including attorney’s fees) and an equal share of the expenses of the mediator and arbitrator and the fees of the AAA. The parties, their representatives, other participants and the mediator and
arbitrator shall hold the existence, content and result of the mediation and arbitration in confidence. Nothing in this clause shall be construed to preclude any party from seeking injunctive relief in order to protect its rights pending mediation
or arbitration. A request by a party to a court for such injunctive relief shall not be deemed a waiver of the obligation to mediate or arbitrate. 
  
 10.15 Non-Exclusive Market Rights 
  
 It is expressly understood and agreed that this Agreement neither grants to Supplier an exclusive right or privilege to sell to Company any or all material or services of
the type described in this Agreement which Company may require, nor requires the purchase of any material or services from Supplier by Company. It is, therefore, understood that Company may contract with other manufacturers and suppliers for the
procurement of comparable material or services. In addition, 
  

 - 51 - 

 Company shall at its sole discretion, decide the extent to which Company will market, advertise, promote, support, or
otherwise assist in further offerings of the material or services. Supplier agrees that purchases by Company under this Agreement shall neither restrict the right of Company to cease purchasing nor require Company to continue any level of such
purchases.

 All material shall be provided free from all claims, liens and charges whatsoever. Company
reserves the right to require, before making payment, proof that all parties furnishing labor and material have been paid.

 Supplier agrees to submit to Company all advertising, sales promotion, press releases, and other publicity matters relating to the material furnished or the services performed by Supplier under this Agreement wherein
Company’s names or marks are mentioned or language from which the connection of said names or marks therewith may be inferred or implied; and Supplier further agrees not to publish or use such advertising, sales promotion, press releases, or
publicity matters without Company’s prior written approval. This does not reduce or modify Supplier’s obligations under the clause IDENTIFICATION. 
  
 10.18 Releases Void 
  
 Neither party shall require (i) waivers or releases of any personal rights or (ii) execution of documents which conflict with the terms of this Agreement, from employees, representatives or customers of the other in

site of the Services so that Supplier will not interfere with Company’s operations. Storage space will not necessarily be provided adjacent to the site of the Services. Therefore, Supplier shall be expected to select, uncrate, remove and
transport Hardware and Software from the storage areas provided. Company is not responsible for the safekeeping of Supplier’s property on Company’s premises. Supplier shall not stop, delay or interfere with Company’s work schedule
without the prior approval of Company’s

protect Company’s stock, equipment and other property from damage due to Supplier’s performance of the Services. 
  
 10.20 Severability 
  
 If any of the provisions of this Agreement shall be invalid or unenforceable, such invalidity or unenforceability shall not invalidate or render unenforceable this entire Agreement, but rather this entire Agreement
shall be construed as if not containing the particular invalid or unenforceable provision or provisions, and the rights and obligations of the parties shall be construed and enforced accordingly. 
  
 10.21 Supplier’s Employees 
  
 The term Supplier employee means anyone performing the Work or furnished by Supplier under
this Agreement, including but not limited to the Supplier’s employees, consultants, representatives, agents, subcontractors, and subcontractors’ subcontractors at all tiers. It is agreed that all persons provided by Supplier to perform the
Work are not employees or agents of Company, and Company shall not exercise any direct control or supervision over Supplier employees but Company’s Representative will be available for consultation. 
  
 Supplier shall be responsible for its own labor relations with any trade or union, which
represents its employees and shall be responsible for negotiating and adjusting all disputes. Supplier shall be the sole entity responsible for receiving complaints from Supplier employees regarding their assignments and for notifying Supplier
employees of the termination or change of their assignments. Company has the right at any time (prior to and after assignment to Company’s Work) and for any reason to reject or to have Supplier remove Supplier’s employees from the Work
under this Agreement upon notice to Supplier. Upon such notice, Supplier shall, at Company’s request, replace the Supplier employee(s). In the event of any staffing change, Company shall not be charged for the time required to train the
replacement. The amount of non-compensatory training time, if any, shall be mutually determined by Supplier and Company’s Representative. 
  
 Supplier further agrees that any of Supplier’s employees who is or becomes a `leased employee’ (as defined in Section 414(n) of the Internal Revenue Code) of
Company during the term of this Agreement, shall not be covered by, and shall be excluded from participation in, any employee benefit plan maintained by Company. Supplier shall indemnify and save Company harmless from and against any losses,
damages, claims, demands, suits, and liabilities that arise out of, or results from, any failure by Supplier to perform its obligations under this clause. Supplier shall also indemnify and save Company harmless from any entitlement, assertion, or
claim, which any of Supplier’s employees might have or might make relative to rights or privileges in any Company employee benefit plan and which arises, in whole or in part, out of Work rendered under this Agreement.

 10.22 Utilization of Minority and Women-owned Business Enterprises 
  
 It is Company’s policy that minority and women-owned business enterprises (MWBEs) as
defined in Exhibit D shall have the maximum practicable opportunity to participate in the performance of contracts. Supplier agrees to use its good faith efforts to award subcontracts and/or utilize MWBEs to carry out this policy to the fullest
extent consistent with the efficient performance of this Agreement and without compromise of quality and reliability expectations. 
  
 In addition to these general conditions for MWBE support, Supplier agrees to (a) use its good faith efforts to utilize MWBEs in support of this Agreement and strive to
increase the percentage of total expenditures from MWBEs to fulfill Company’s purchases each successive year of this Agreement; (b) support Company’s state and regional goals for MWBE and service-disabled veterans (SDVs) spending in
California and other states/regions as may be defined in the future; and (c) work with Company to develop opportunities for the utilization of MWBEs for first tier procurement by Company. 
  
 10.23 Waiver 
  
 An effective waiver under this Agreement must be in writing and signed by the party waiving its right. A waiver by either party of any instance of the other party’s
noncompliance with any obligation or responsibility under this Agreement will not be deemed a waiver of subsequent or other prior instances of non-compliance.

 Exhibit E 
 Escrow Agreement 
  
 Agreement made this 21
day of December, 2000, among Fort Knox Escrow Services, Inc. (hereinafter referred to as “Agent”), Avici Systems, Inc., a Delaware corporation, (hereinafter referred to hereafter as “Supplier”), and AT&T Corp., a New York
corporation (hereinafter referred to as “Company”), and with respect to which the parties agree as follows: 
  
 Background 
  
 1. Company has issued and Supplier has accepted Contract Number #20001130.2.C, for the License of Supplier’s Software, and associated Services from Supplier; and 
  
 2. Company’s ability to use Supplier’s Software without Software Source
Material would be seriously jeopardized upon the occurrence of certain events; and 
  
 3. Contract Number #20001130.2.C for the License contains a section entitled “Source Programs and Technical Documentation” in which Supplier agrees to enter into an Escrow Agreement to assure the availability to Company of
Software Source Material. 
  
 Definitions 
  
 Any provision of this Agreement, which is in capital letters, shall have the meaning set
forth in the Definitions Appendix attached to this Agreement, whether or not such provision is differently defined elsewhere. 
  
 Deposit in Escrow 
  
 1.Supplier shall deliver to Agent within thirty (30) business days from the date of this Agreement a complete package of the media conveying Software
Source Material. Upon delivery in escrow, the right to beneficial use of the Software Source Material shall vest in Company, subject solely to the conditional right to immediate possession thereof as set forth in this Agreement. Agent
shall not be responsible for the accuracy or completeness of the Software Source Material except to determine that the package contains the material listed in the letter transmitting the Software Source Material to Agent. 

 
 2. Supplier shall not during the duration of this Agreement sell, pledge,
assign or otherwise transfer, dispose of or encumber its interest in the Software Source Material conveyed to Agent or the media conveying it without the prior written consent of Company. Nothing herein shall impair the right of Supplier to
use or sell any trade secret or other proprietary information, which is the same as, or is a copy of the information embodied in the Software Source Material held by Agent. In the event of a merger, or the acquisition of all or substantially
all of Suppliers assets, title to the Software Source material as deposited with Agent may be transferred to the surviving entity, and this Escrow Agreement assigned accordingly, upon notice to Agent and Company. 
  

 - 71 - 

 Deposit of Changes 
  
 [CONFIDENTIAL TREATMENT REQUESTED] /*/. Under no circumstances shall the Agent return to Supplier any Software Source
Material or delete from the Software Source Material any part thereof. Agent shall not be responsible for the accuracy, completeness or timeliness of Changes submitted to it except to determine that the package consists of the
items listed in the letter transmitting the Changes to Agent. 
  
 Confirmation of Receipt 
  
 Agent shall deliver
to Supplier and Company written confirmation of receipt of any Software Source Material or Changes received pursuant to the Deposit in Escrow and Deposit of Changes clauses within three (3) business days from
receipt thereof. The confirmation shall consist of a listing of the items of Software Source Material or Changes, as the case may be, delivered together with a list of items of Software Source Material affected by the
Changes. 
  
 Review of Software Source Material and
Changes 
  
 1. If requested in writing
by Company, Supplier shall deliver to Company a complete fully documented copy of any Software Source Material to be placed in escrow. Supplier shall, in the presence of Company’s technical representative, compile the Software Source
Material and test the resulting object code to verify that the delivered Software Source Material is sufficient and complete for the purpose of this Agreement. If such tests confirm that the Software Source Material is sufficient
and complete, the verification shall be reduced to writing and signed by Company and Supplier. The sole purpose of such review is to preliminarily verify that the Software Source Material contains sufficient technical information for the
purpose stated in this Agreement. No copies or notes thereof shall be made or taken by any of the reviewing personnel. 
  
 2. Supplier also agrees to submit Changes to the same review and approval procedure used for the Software Source Material prior to
submission of the Changes to Agent. 
  
 3. If as a result
of the evaluation set forth in Paragraphs 1 and 2 of this clause any portion of the Software Source Material is found to be incomplete or inadequate to enable Company to use the same for the purposes stated in this Agreement, Supplier agrees
to promptly furnish to Company any and all technical information required to correct such deficiency in the Software Source Material and to make such Software Source Material complete. 
  
 4. Upon completion of the verification described in Paragraphs 1 and 2 of
this clause, Company shall, in the presence of a representative of Supplier deposit the verified Software Source Material in a sealed container and give it to Agent. Company agrees not to break the seal on the container unless and until the
contingencies set forth in the Causes for Release from Escrow clause are met. 
  

 - 72 - 

 5. If Company assumes responsibility for the Software Source Material in accordance with the
Causes for Release from Escrow clause of this Agreement, [CONFIDENTIAL TREATMENT REQUESTED] /*/, Supplier may, at the Company’s sole discretion, as of a date mutually agreed upon by Company and Supplier, reassume such responsibilities if
Supplier has fully remedied any such Causes for Release from Escrow to the Company’s satisfaction.. In such case Supplier shall, as of the mutually agreed date, recommence such [CONFIDENTIAL TREATMENT REQUESTED] /*/. Upon such resumption by
Supplier, Company shall remove the Software Source Material from the custody of its technical employees, replace the media containing the Software Source Material in a sealed container then returned to Agent, and shall [CONFIDENTIAL
TREATMENT REQUESTED] /*/. Any Use by Supplier outside [CONFIDENTIAL TREATMENT REQUESTED] /*/. 
  
 Protection of Software Source Material 
  
 Software Source Material may be furnished under this Agreement with restrictions if it is in human- readable form and clearly marked as proprietary. Company, for [CONFIDENTIAL TREATMENT REQUESTED] /*/after the
expiration or termination of Contract Number GA 20001130.2.C, shall hold the Software Source Material in confidence, shall use the Software Source Material only as provided in the License, and shall not disclose the Software
Source Material to any third party without prior written approval of the Supplier. Company’s use of Software Source Material shall include the disclosure to and use by any of its Affiliates (as defined in Contract Number GA
20001130.2.C), provided they are under a duty to treat the Software Source Material AS provided in this clause. 
  
 Company shall not be liable for the inadvertent or accidental disclosure of Software Source Material, if the disclosure occurs despite the exercise of the same
degree of care as Company normally takes to preserve its own such proprietary information of like character. 
  
 These restrictions on the use or disclosure of Software Source Material shall not apply to Software Source Material: 
  
 i. independently developed by or for company or lawfully received from another source free of restriction by that source and without breach
of this Agreement; or 
  
 ii. which is or becomes generally available to the
public without breach of the Agreement by Company; or 
  
 iii. which at the time
of disclosure was known to Company free of restriction by another; or 
  
 iv.
which was fixed in media not marked as proprietary when furnished to Company. 
  
 The Software Source Material shall remain the property of Supplier and shall be returned upon Company’s determination that it no longer has a need for the Software Source Material or as 
  

 - 73 - 

 provided in the Review of Software Source Material and Changes clause. Company may, however, retain one
copy of all written materials returned to provide an archive record of the disclosure, and not to be used for operational purposes. 
  
 Causes for Release from Escrow 
  
 Upon the giving of Notice to Agent by Company that one or more of the following conditions exists, Agent shall proceed in accordance with the
Procedures clause: 
  
 [CONFIDENTIAL TREATMENT REQUESTED] /*/

  

 - 74 - 

 Procedures 
  
 Within three (3) business days following receipt of the Notice, Agent shall serve a copy of the Notice on Supplier and shall confirm such
delivery in writing to Company. 
  
 1. If Agent does not receive
(i) a written statement from Company withdrawing the Notice or (ii) a Counternotice from Supplier within fifteen (15) business days of the service of Notice on Supplier, Agent shall forthwith deliver the Software Source
Material to Company. 
  
 2. If Agent receives from Company
within the fifteen (15) business day period a written statement withdrawing the Notice, Agent shall notify Supplier of such withdrawal and this Agreement shall continue in full force and effect as if no Notice had been communicated to
Agent. 
  
 3. If Supplier disputes the existence of all the
conditions upon which the Notice is based, Supplier shall within the fifteen (15) business day period give to Agent a Counternotice. If the Counternotice is received by Agent before the close of business on the last business day
of such period, Agent shall, within three (3) business days of receipt of the Counternotice, serve the Counternotice on Company and withhold delivery of the Software Source Material pending receipt of either (i) a certified copy
of the award of the Arbitrator pursuant to the Mediation and Arbitration clause of this Agreement or (ii) other instructions signed jointly by Supplier and Company. 
  
 4. Notwithstanding any other provisions of this Agreement, Agent shall promptly deliver the Software Source Material
to the party designated in writing signed jointly by Supplier and Company. If no such writing is received and this Agreement terminates other than by reason of delivery of the Software Source Material to Company, Agent shall deliver the
Software Source Material to Supplier. 
  
 5. Right to
unrestricted possession, subject to the terms of this Escrow Agreement of the Software Source Material shall vest in Company upon Agent’s delivery thereof to Company and Company may use the Software Source Material without payment
of any nature to Supplier. 
  
 Mediation and Arbitration 
  
 If a dispute arises out of or relates to this Agreement, or its breach, and the parties have
not been successful in resolving such dispute through negotiation, the parties agree to attempt to resolve the dispute through mediation by submitting the dispute to a sole mediator selected by the parties or, at any time at the option of a party,
to mediation by the American Arbitration Association (“AAA”). If not thus resolved, it shall be referred to a sole arbitrator selected by the parties within thirty days of the mediation or, in the absence of such selection, to final and
binding arbitration by a sole arbitrator under the AAA Arbitration Rules (“Rules”) in effect on the date of this Agreement. The mediation and arbitration, including arguments and briefs, shall be in the English language in New York City,
New York, United States of America. The arbitrator may not limit, expand or otherwise modify the terms of this Agreement or award exemplary or punitive damages or attorney’s fees. The arbitrator shall apply the substantive (not the conflicts)

  

 - 75 - 

 law of the state specified in the choice of law provision set forth elsewhere in this Agreement. The award shall be in
United States dollars. Judgment upon the award rendered in the arbitration may be entered in any court having jurisdiction thereof. Each party shall bear its own expenses (including attorney’s fees) and an equal share of the expenses of the
mediator and arbitrator and the fees of the AAA. The parties, their representatives, other participants and the mediator and arbitrator shall hold the existence, content and result of the mediation and arbitration in confidence. Nothing in this
clause shall be construed to preclude any party from seeking injunctive relief in order to protect its rights pending mediation or arbitration. A request by a party to a court for such injunctive relief shall not be deemed a waiver of the obligation
to mediate or arbitrate. 
  

 - 76 - 

 Agent Charges 
  
 All fees and expenses, including reasonable attorneys’ fees, charged by Agent for its activities under this Agreement shall be borne solely by
Supplier. If Supplier fails to pay such charges, Agent shall promptly so notify Company. Company shall either (i) authorize Agent to terminate this Agreement and return the Software Source Material to Supplier or (ii) give Notice to
Agent to deliver to Company the Software Source Material. 
  
 Duration

  
 This Agreement shall continue in effect so long as
Contract number GA 20001130.2.C in effect, or any software licensed by Company is being used by Company or its customers, and Company is contractually bound to provide warranty support and maintenance to said customer(s). Provided, however that this
Agreement shall not have been earlier terminated either (i) by delivery of the Software Source Material as provided in this Agreement or (ii) by Company authorizing the Agent to return the Software Source Material to the Supplier.

  
 Agents Rights and Responsibilities 
  
 1. Agent shall not be under any duty to give the Software Source
Material held under this Agreement any greater degree of care than it gives its own similar property. 
  
 2. With respect to Company, Agent may act in reliance upon any written instrument signed by a member of Company’s Supplier Management Division.

  
 3. With respect to Supplier, Agent may act in reliance upon
any written instrument signed by an officer of Supplier. Any writing to Agent by an officer of Supplier shall be accompanied by a Certificate of Incumbency by the Secretary or Assistant Secretary of Supplier, which shall state that the person
signing the writing is an officer of Supplier as of that date. 
  
 4. Agent may act upon advice of counsel in reference to any matter connected with this Agreement and shall not be liable for any mistake of fact or error of judgment, or for any acts or omissions of any kind, unless caused by its willful
misconduct or gross negligence. 
  
 5. This Agreement sets forth
the exclusive duties of Agent with respect to any and all matters pertinent to such duties. 
  
 6. Agent shall not be obligated to advise any party as to its rights and obligations under this Agreement. 
  
 7. Agent does not have and will not have any interest in the Software Source Material or any part thereof held under this Agreement other than as
escrow holder having possession of the Software Source Material.
