	1.		Any subsequent net adjustment, by audit or otherwise, that increase prior quarter Nortel royalty reports will not retroactively count towards any quarterly billing threshold target.
	2.		Any subsequent net adjustments, by audit or otherwise, that decrease prior quarter Nortel royalty reports that would have placed Nortel in a lower purchase credit level but for such reporting error (i.e. the difference defined as the “Unearned Credit”) will result in the cancellation of such Unearned Credit (if not already applied to the relevant Airvana invoice) or a cash refund to Airvana in the amount of the Unearned Credit (if already applied on a relevant Airvana invoice)
	3.		For purposes of calculating the billing threshold in any calendar quarter, ▇▇▇▇▇▇▇▇ shall mean amounts invoiced in respect to such calendar quarter based upon Nortel royalty reports and Nortel Orders for maintenance and other services, excluding any credits earned in accordance with this Amendment No. 10 and such invoice shall include prices of all Products sold or licensed by Nortel less any specially negotiated discounts not accounted for in such invoice.

	3.		For purposes of calculating the billing threshold in any calendar quarter, ▇▇▇▇▇▇▇▇ shall mean amounts invoiced in respect to such calendar quarter based upon Nortel royalty reports and Nortel Orders for maintenance and other services, excluding any credits earned in accordance with this Amendment No. 10 and such invoice shall include prices of all Products sold or licensed by Nortel less any specially negotiated discounts not accounted for in such invoice.

8.

Unless otherwise prohibited by a customer confidentiality agreement, the parties agree to review reasonable information relating to Nortel’s customer installed base, including information relating to DOMs, EMS licenses, RNCs and associated cards, and any other Product based on available Nortel information. Thereafter, if not otherwise prohibited by customer confidentiality agreements, such information relating to Nortel’s installed

customer base shall be updated upon Airvana’s request but no more frequently than once per calendar quarter using similar methodologies and relevant Nortel information.

9.

The parties agree to good faiths efforts to evaluate improved licensing and reporting mechanisms and to use reasonable efforts to implement a mutually agreed to solution.

10.

[**]: Airvana agrees to review in good faith [**] opportunities requested by Nortel. Additional discounts, if any, shall be as mutually agreed in writing by the parties on a case by case basis.

11.

12.

Nortel will accept Products for deployment in customer networks (“Product Acceptance”), based on either of the two following circumstances applying to the Products:

a.) Nortel’s declaring Channel Ready the product bundle that includes the applicable Airvana Products based on Airvana’s compliance to the feature requirement specifications and Nortel confirms in writing to Airvana such Product Acceptance; or
b.) Upon the parties entering into a written agreement (i) identifying non-conformities to the feature requirement specifications; (ii) detailing a technical solution to the non-conformities to be implemented by Airvana or Nortel’s acceptance of a commercial resolution, and (iii) Nortel’s subsequent declaration that the product bundle that includes the applicable non-conforming Airvana Products is Channel Ready.

For greater certainty Nortel will not declare Channel Ready products that include an Airvana Product in the absence of Product Acceptance of such Product. For the purposes of this section Channel Ready shall mean, the determination by Nortel of the acceptability of an applicable bundle of products for deployment.

13.

For greater certainty, the pricing set forth in Appendix A(5) is only applicable to transactions occurring after the Effective Date and such pricing does not supersede any special pricing previously agreed between the parties.

14.

Section 9.2 (f) Case Severity Definition and Closure Policy (Production Hardware and Software), is deleted in its entirety and replaced by the following new Section 9.2(f).

9.2

(f) Case Severity Definition and Closure Policy (Production Hardware and Software): For production Hardware and Software, the classifications using the following definitions as the guideline follow:

Critical (E1): Actual outage of equipment which, depending on product, could mean failure to process calls, loss of service to end customers, or similar. Immediate and continuous effort is required until the service level has been restored to pre-incident operation. As these are business imperative faults, they may require considerable re-deployment of resource by both Nortel and the customer, and management awareness is required by both sides in order to progress. Upon resolution of an E1 issue, the E1 is closed and an E3 is opened to follow up (see below explanation.)

E2: Potential outage of equipment, such as loss of resilience, imminent failure of cards, fatal errors, etc. Immediate and continuous effort is required until the service level has been restored to pre-incident operation. As these are business imperative faults, they may require considerable re-deployment of resource by both Nortel and the customer, and management awareness is required by both sides in order to progress. Upon resolution of an E2 issue, the E2 is closed and an E4 is opened to follow up (see below explanation.)

E1/E2 CRITERIA

[**].

BUSINESS CRITICAL: Although this issue is defined as being non-emergency, it must be handled with the highest priority. Business Critical issues receive focused management and resource attention. These issues are treated as critical by agreement between the customer and Nortel at a management level, and include loss of revenue, or other special cases such as the requirement to route calls via other operators, although no actual outage occurs

MAJOR: Service affecting Issues. This category includes any software errors or hardware troubles which effect service or possibly affects the customer’s ability to collect revenue but cannot be classified as either Emergency or Critical.

E3: Root cause analysis or preventative work, following from an E1 fault.

MINOR: Non-service affecting condition. This category includes hardware and software difficulties that are not E1/E2/Critical and primarily relate to minor hardware faults or errors in documentation, which do not lead to mis-operation of equipment.

E4: Root cause analysis or preventative work, following from an E2 fault.

15.

Section 9.2 (g) Escalation Procedure, is hereby deleted in its entirety and replace by a new section 9.2 (g) below:

9.2 (g) Escalation Procedure: During the work day at Airvana, resources shall ordinarily be available to answer a call; however, there could be times when a support call could go to voice mail. The call back time target if a call goes to voice mail is [**]. Failure of Airvana Technical Support to respond within [**] of a voicemail message will be escalated to the following Airvana managers, in order of escalation:

1.) ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, Support Manager Technical Support
           Phone: [**]
           Mobile: [**]

2.) ▇▇▇▇ ▇▇▇▇▇▇▇▇, Director of Technical Services
           Phone: [**]
           Mobile: [**]

3.) ▇▇▇▇ ▇▇▇▇▇▇▇, VP of Sales and Technical Services
          Phone: [**]
          Mobile: [**]

4.) ▇▇▇▇▇ ▇▇▇▇▇▇, President and CEO
          Phone: [**]

          Mobile: [**]

16.

Section 9.2(h) Target time to resolve within receipt of initial fault report, is hereby deleted in its entirety and replace a new Sections 9.2 (h) below:

9.2 (h) Issue resolution:

i.) For customers covered under a maintenance and support plan, AIRVANA shall use reasonable commercial efforts to repair Product that fails to materially comply to the specifications. The parties will meet within 30 days and mutually agree on a resolution plan in connection with such Product repair. Failure to agree on a resolution plan will be considered a failure to materially support Nortel’s support requirements under Appendix C Section 10B(a)

ii.) Target time to resolve within receipt of initial fault report: AIRVANA shall use Reasonable Efforts to provide resolution in accordance with the table below:

Table Customer Care Case Responsiveness Requirements

Emergency Cases		Percentage				Service Restored (outage start to system recovery)
E1			[**]	%		in [**]
E1			[**]	%		in [**]
E2			[**]	%		in [**]

Software Cases		Percentage		RCA Identified		Resolved
E3		[**]%		< [**]		< [**]
BC		[**]%		< [**]		< [**]
MJ		[**]%		< [**]		< [**]
MN		[**]%				< [**] to identify fix plan for future release

Non Software Cases		Percentage				Resolved
E3, BC, MJ, MN		[**]%		n/a		< [**]

Notes:

	•		Software cases are those which require a software fix
	•		Minor software fixes are normally to be addressed in future releases only. Target release is the next release and is to be based on fix complexity and release capacity
	•		All measurements are in calendar days
	•		All measurements include resolution time shared between Nortel TAS, Nortel ER, VO and Airvana
	•		Targets listed above wrt Airvana response targets are as clarified below in 15.5.3.2 item 6.
	•		Time is measured from the actual instance of a customer occurrence
	•		For fixes delivered in the current release, EVDO corrective content is normally delivered as a patch load on a monthly schedule. To determine resolved dates of software corrective content, Airvana will provide details of when the software solution is submitted in a patch stream.  The requirement is that solution has been coded and unit tested by Airvana.  The build number for the specific software solution will need to be updated in [**] to determine resolution date. The actual closure of the case will be done after customer has validated the solution. Airvana will continue to track when the fix solution was identified (Solution Defined Date) prior to coding/testing since coding/testing dates will be driven by monthly patch load schedules and/or customer priority
	•		For fixes to be delivered in a future release stream, Airvana will provide a committed release stream for the fix in [**] to determine resolution date.  The fix must be coded and fully validated by CuR of the future release.  The case will be updated with the fix/build_id when it becomes available. The case will remain open pending delivery of the release and actual closure of the case will be done after the customer has validated the solution.

17.

In all other respects the Agreement, as amended, remains unchanged.

IN WITNESS WHEREOF, the parties have caused this Amendment No. 10 to be signed by their duly authorized representatives as of the Effective Date, although actually signed by the parties on the dates set forth below their respective signatures.
