 EXHIBIT 10.22 
  

			
	 

	  	STANDARD PURCHASE AND LICENSE TERMS

 NOTICE: The terms and conditions contained herein apply to the purchase and license of Sonus hardware and
software products described on Attachment A (“Products”). Any terms and conditions on Buyer’s purchase order (“Order”), which are in addition to, or conflict or are inconsistent with these terms are superceded by the terms
contained herein. 
 1. All shipments are F.O.B. Sonus’ facility. Except as otherwise requested, Sonus will select the carrier. Packaging is in
accordance with standard industry practices. Buyer bears costs of transportation, shipping, and insurance, as well as all applicable taxes. Risk of loss and title (except for software) passes to Buyer upon delivery to the carrier. Sonus will use
reasonable efforts to ship Products on the scheduled shipment date, but is not liable for failures to meet such date. Sonus may allocate shipment of Products among purchasers and may make partial shipments. Buyer may, one time, reschedule the
delivery of Products, by written request, up to thirty (30) days prior to scheduled ship date, within the same calendar quarter at no charge. Reschedule requests received less than thirty (30) days prior to ship date are at Sonus’
sole discretion. Buyer may cancel any shipment without charge with at least sixty (60) days’ written notice prior to the originally-scheduled ship date. 
 2. Shipments to non-US destinations must comply with applicable export and import regulations. Buyer is solely responsible for securing import license(s), local customs clearance and paying all duties, taxes and other charges. Buyer will
indemnify and hold Sonus harmless from and against claims, losses, costs, or liability, due to Buyer’s breach hereof. Sonus’ reasonable delay or refusal of shipping due to export or import issues does not constitute default. 
 3. Subject to credit approval, and except for the first shipment under this Agreement described on Attachment A (the “Initial Shipment”), which shall be
invoiced as set forth below, Sonus will invoice Buyer upon shipment. Buyer will pay all invoices in US dollars within 30 days of invoice date. Payment for the Initial Shipment will be due 30 days following acceptance (as defined below), or by
June 15, 2005, whichever is earlier. Sonus may withhold shipments until past-due payments are made, and may require subsequent orders to be paid for in advance. Late payments are subject to a charge of 1.5% per month, or the maximum
allowed by law, for each month, or partial month, payment is late as well as collection costs, including reasonable collection and attorney’s fees. Unless otherwise directed by Sonus, all such invoices will be payable by wire transfer, to the
following account, in United States dollars: Silicon Valley Bank 3003 Tasman Drive, Santa Clara, CA 95054 Account: 3300080864 Routing: 121140399 Account Name: Sonus Networks, Inc, or by check, via overnight courier to: Dennis Bilodeau / Accounts
Receivable, Sonus Networks Inc., 250 Apollo Dr., Chelmsford, MA 01824. Prices do not include and Buyer shall be responsible for all taxes of any kind due in respect of the transactions contemplated by this Agreement, except taxes on Sonus’ net
income. 
 Products shipped as part of the Initial Shipment are for use in a test environment only. For the Initial Shipment, Buyer will have 60 days from
the date of shipment (the “Test Period”) to accept or reject the Products. The parties may mutually agree in writing to extend the Test Period by an additional 30 days. If Buyer wishes to reject the Products, it must do so in writing
(including a description of the reasons for the rejection), and rejection, regardless of the reasons for the rejection, will result in the cancellation of the purchase order covering the Products. If Buyer does reject the Products, it must return
the Products, at Customer’s expense, in the same condition as they were delivered (reasonable wear and tear excepted) within 15 days. Failure to reject the Products in writing within the Test Period will be deemed acceptance of the Products.
Following acceptance (whether by written notice or expiration of the Test Period), Sonus will issue an invoice to Buyer for the Products. [***]. Following acceptance of the Initial Shipment, Buyer will purchase maintenance support as described on
Attachment C. The standard payment terms described above (i.e., net 30) will apply to all subsequent orders after the Initial Shipment. 
 4. Sonus will
provide reasonable notice of discontinuance or modification of any ordered Product and may modify its price list at any time without notice. Products are subject to changes, including electrical or mechanical design refinements as deemed
appropriate, or as required by law or safety concerns, without obligation to modify or change Product previously delivered or to supply Products in accordance with earlier specifications. 
 5. Subject to Buyer’s compliance with the terms of this agreement (including payment of all applicable fees), Sonus grants Buyer a nonexclusive, nontransferable
license to use the software Product object code solely for its internal business purposes with the hardware with which it is was first supplied. Buyer may not permit use of the software by another party (including but not limited to network, remote
computing services or timesharing use) without the prior written consent of Sonus; provided, however, that Buyer may use the software portion of the Products to provide voice, fax, data, video and other communications management services to those
clients of Buyer that obtain such services from Buyer under the provisions of a separate communications services agreement as part of Buyer’s business. Sonus (and its’ licensors) retain all rights, title and interest, including all
intellectual property rights, in the Products, including the software Products. Buyer may reproduce 1 copy of the software Products solely for back-up purposes. Buyer may not copy, translate, modify or adapt the software Products or incorporate
them, in whole or any part, in any other product, create derivative works based on the Products, or license others to reproduce any copies of the software Products, and may not decompile, disassemble or reverse engineer the software Products, or any
component thereof. Buyer will ensure that all proprietary notices affixed to or displayed on the software Products will not be removed or modified. Upon termination of this license by Sonus for any reason, Buyer will immediately cease use of the
software and related documentation and return all copies to Sonus.

software is acquired under the terms of a Department of Defense or civilian agency contract, the software is “commercial item” as that term is defined at 48 C.F.R. 2.101 (Oct. 1995), consisting of “commercial computer software”
and “commercial computer software documentation” as such terms are used in 48 C.F.R. 12.212 of the Federal Acquisition Regulations and its successors and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995) of the DoD FAR Supplement and its
successors. All U.S. Government end users acquire the software with only those rights set forth herein. Manufacturer is Sonus Networks, Inc., 5 Carlisle Rd, Westford, MA 01886, USA. Unpublished - rights reserved under US copyright laws. 

7. LIMITED WARRANTY Product hardware and media are warranted to be free from defects in material and workmanship and will conform substantially to Sonus’
published user documentation, as of the date of Product shipment, during the applicable Warranty Period (WP). The WP is 12 months from delivery for hardware, 90 days for software, and 30 days for media. Sonus warrants the Products, including
software, as follows: (a) dates advance normally and date rollovers do not produce erroneous data and/or processing; (b) Products and/or software calculate and manipulate date data correctly and reliably over the range of dates the
application is expected to handle; (c) Products and/or software explicitly display and store the century values (four digits) eliminating ambiguity and potential errors; and (d) for any date not explicitly displayed within the Products
and/or software, the correct century is unambiguous for all manipulations involving that element and is displayed using at least two-digits for the year. For any defect in which Sonus is unaware, Sonus is not liable hereunder if Buyer fails to
provide notice of an alleged defect during the WP and within thirty (30) days of its discovery. After receiving such notice, Sonus’ Technical Assistance Center will notify Buyer of its designation of one of its standard problem resolution
methods. Sonus’ sole liability, and Buyer’s sole and exclusive remedy, for defects is limited to the express remedies set forth herein, which shall include repair or replacement of the defective Product. SONUS MAKES NO OTHER WARRANTIES,
EXPRESS, IMPLIED OR STATUTORY, IN CONNECTION WITH THIS AGREEMENT. ALL OTHER WARRANTIES AS TO THE QUALITY, CONDITION, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NONINFRINGEMENT ARE EXPRESSLY DISCLAIMED. Sonus will repair or, at its option,
replace defective hardware not covered under warranty at its standard charges. Buyer may purchase maintenance support services under a separate, written agreement. Software is not warranted to be error free. 
 8. SONUS IS NOT LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES OR LOST PROFITS, FORESEEABLE OR UNFORESEEABLE, OF ANY KIND
(INCLUDING, WITHOUT LIMITATION, LOSS OF GOODWILL, LOST OR DAMAGED DATA OR SOFTWARE, LOSS OF USE OF PRODUCTS, OR DOWNTIME), WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), PRODUCT LIABILITY OR OTHERWISE, ARISING FROM THE SALE AND
DELIVERY OF PRODUCTS OR SERVICES OR ANY OTHER ACT, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. EXCEPT AS OTHERWISE PROVIDED UNDER SECTION 9, SONUS’ MAXIMUM LIABILITY FOR DIRECT DAMAGES, WHETHER BASED ON WARRANTY, CONTRACT, TORT
(INCLUDING NEGLIGENCE), PRODUCT LIABILITY OR OTHERWISE, WILL NOT EXCEED THE PRICE PAID FOR THE AFFECTED PRODUCT. THE FOREGOING LIMITATIONS SHALL APPLY NOTWITHSTANDING THE FAILURE OF ANY EXCLUSIVE REMEDIES. NO LIMITATION AS TO DAMAGES FOR PERSONAL
INJURY IS HEREBY INTENDED. 
 9. Sonus will indemnify and hold Buyer harmless from and against valid claims and any resulting damages, costs or liabilities
awarded by a court of final jurisdiction that the Products infringe any United States patent, copyright, trade secret or trademark of a third party. Sonus’ indemnification obligation is subject to Buyer’s compliance with the following
procedures: (a) Buyer will promptly notify Sonus in writing of any claim or the commencement of any suit, action, proceeding or threat that Buyer believes will result in losses for which it will be entitled to indemnification; (b) Buyer
will tender to Sonus (and its insurer) full authority to defend or settle any such claim; and (c) Buyer shall cooperate in the defense of such claim. Sonus has no obligation to indemnify Buyer in connection with any settlement made without
Sonus’ written consent. Sonus will defend Buyer against any such claim brought against Buyer in the United States by counsel retained at Sonus’ own expense. This section 9 shall not apply to infringement or misappropriation claims arising
from (1) designs, specifications or modifications originated or requested by Buyer, (2) the combination of any Product with other equipment, software or products not supplied by Sonus if such infringement or misappropriation would not have
occurred but for such combination, or (3) Buyer’s failure to install an update provided at no additional charge, where same would have avoided such claim. Buyer will indemnify and hold Sonus harmless from and against claims that are the
subject of clauses (1)-(3). In the event that the use or sale of the Products is enjoined, or, in Sonus’ judgment, may be enjoined, Sonus will either: (i) procure for Buyer the right to continue to use the Product, or (ii) replace or
modify the infringing or misappropriating Product so that it becomes non-infringing with functional equivalent product. In the event that the foregoing alternatives cannot be reasonably accomplished by Sonus, Sonus shall direct Buyer to return the
Product to Sonus and upon receipt of the Product(s), Sonus shall reimburse Buyer for the price originally paid by Buyer as depreciated by an equal annual amount over the lifetime of the Product assuming five year straight line depreciation. Upon
Sonus’ fulfillment of the alternatives set out in this Section 9, Sonus shall be relieved of any further obligation or liability to Buyer as a result of any such infringement or misappropriation. THIS SECTION 9 STATES SONUS’ ENTIRE
LIABILITY TO BUYER AND BUYER’S SOLE REMEDY FOR ANY INFRINGEMENT CLAIMS CONCERNING THE PRODUCTS OR RELATED SERVICES. 
 10. Either party may terminate
this agreement with thirty (30) days notice if the other party materially breaches this agreement unless such breach is cured within said thirty (30) day period; provided that either party may immediately terminate this agreement upon
notice if the other party breaches Section 5.

entire agreement of the parties with respect to the transactions contemplated by this agreement and supersedes all prior and contemporaneous agreements, representations and understandings, whether written or oral. No modification or waiver of any
provision hereof is effective unless in writing and signed by each party. No failure or delay by either party in exercising any right or remedy hereunder will operate as a waiver of same. This agreement is binding upon and inures to the benefit of

 INSTALLATION SERVICES 
  

	A.	Sonus will provide the following services [***]: 

 1) Install the GSX
switch (a Buyer representative must provide assistance with rack mounting of the gear) 
 2) Configure the GSX switch to communicate with its NFS elements(s)

 3) Confirm connectivity to the IP or ATM, data/signaling, and management networks. 
 4) Ensure that all of the GSX modules pass their individual POST diagnostics. 
 5) If the Management “network” is
available at installation time, then Sonus personnel will connect the management interface cable(s) to the GSX9000 and validate that the system loads its operational SW code/configuration.

defective component to Sonus by Customer or Customer personnel (or by site personnel contracted for by Customer). Sonus will assume all costs associated with the shipment of the replacement component(s) and the return of the failed component(s).
Customer shall return the malfunctioning hardware product to Sonus within ten days of the receipt of the replacement product. If Customer does not return any failed component to Sonus in accordance with these procedures, Sonus reserves the right to
charge Customer for the full list price of such unreturned component set forth in the Sonus Price List. If Customer returns a failed component 
 and Sonus
reasonably determines that the part is not defective, then Sonus reserves the right to charge Customer the then-current No Problem Found fee set forth in the Sonus Price List. 
 Advance replacement requests received within the normal business hours of the geographical point of failure will be processed on the same business day. Sonus will make all reasonable commercial efforts to effect
delivery of the replacement hardware component into the designated sparing depot(s) by the specified timescale for those locations where international customs need not be cleared. Requests made after normal business hours will be processed on the
next business day for delivery timescales according to the specified service level.

 ATTACHMENT D 
 PURCHASE PROPOSAL 
 

 
 Sonus Purchase Proposal for 
 

 
 May 19, 2005 
 Executive Summary 
 Sonus is pleased to provide Neutral Tandem with a proposal to move forward with the deployment of the Sonus softswitch
solution for the expansion of the Neutral Tandem POP sites, allowing Neutral Tandem to benefit from the economical and operational efficiencies of the Sonus platform. In the future, Neutral Tandem will be able to offer new revenue-generating
services not available on the legacy circuit switch. Outlined below is a proposal that allows Neutral Tandem to get started in a single production site, deploy a minimum lab configuration with deferred payments, reduce annual maintenance, and
utilize Sonus resources to ensure a successful deployment. We are looking forward to a strong partnership in which Sonus can help Neutral Tandem make a smooth transition to a next generation platform.
