This license shall terminate upon breach of this provision, notwithstanding the cure provisions of 4.2 below.

The parties further agree that this Agreement does not cut off Licensor’s rights to enjoin, control or extract royalties with respect to methods, systems, products, services and/or components of any Third Party.

SECTION 3: CONSIDERATION

3.1 Payment. In consideration of the license, release and covenant granted by Licensor, Licensee agrees to pay to Licensor the license fee(s) in the amount(s) as set forth in Schedule A. The first installment of the annual license fees or the lump sum license fee, whichever the case may be as set forth in Schedule A, shall be paid by Licensee to Licensor no later than five (5) business days after the Effective Date by wire transfer to the following account:

Bank: _________________

In case of the annual licensing fee arrangement as set forth in Schedule A, Licensee agrees to pay to Licensor the annual license fee for each twelve (12)-month period by wire transfer to the above account no later than five (5) business days after the written annual report is made available to Licensor for a given twelve (12)-month period as provided in Section 3.2.

In case of annual licensing fee arrangement as set forth in Schedule A, Licensee agrees to make written annual reports to Licensor within thirty (30) days after the first days of each twelve (12)-month period during the term of the Agreement as set forth in Section 4.1 and as of such dates, stating in each report the number, description, and the aggregate revenues of each Licensed Product sold, delivered, or otherwise disposed of during the preceding twelve (12) months and on which annual licensing fee is payable as provided in Schedule A.

SECTION 5: ASSIGNMENT AND TRANSFER

5.1 No Assignment or Transfer. Licensee agrees that it may not assign or transfer (by contract, merger, succession, sale of business, change of control, operation of law or otherwise) its rights under this Agreement without the prior written consent of Licensor and any attempt to assign without such permission will be void.

6.8 Bankruptcy. Each party irrevocably waives all arguments and defenses arising under 11 U.S.C. 365(c)(1) or successor provisions to the effect that applicable law excuses the party, other than the debtor, from accepting performance from or rendering performance to an entity other than the debtor or debtor in possession as a basis for opposing assumption of the Agreements by the other party in a case under Chapter 11 of the Bankruptcy Code to the extent that consent is required under 11 U.S.C. § 365(c)(1) or any successor statute.

6.9 Severability. If any provision of this Agreement is held to be illegal or unenforceable, such provision shall be limited or eliminated to the minimum extent necessary so that the remainder of this Agreement will continue in full force and effect and be enforceable.

6.10 Entire Agreement. The parties acknowledge, accept, warrant and represent that (i) this is an enforceable agreement; (ii) this Agreement embodies the entire and only understanding of each of them with respect to the subject matter of the Agreement, and merges, supersedes and cancels all previous representations, warranties, assurances, conditions, definitions, understandings or any other statement, express, implied, or arising by operation of law, whether oral or written, whether by omission or commission between and among them with respect to the subject matter of the Agreement; (iii) no oral explanation or oral information by either party hereto shall alter the meaning or interpretation of this Agreement; (iv) the language of this Agreement has been approved by counsel for each of them, and shall be construed as a whole according to its fair meaning, and (v) none of them (nor their respective counsel) shall be deemed to be the draftsman of this Agreement in any action which may hereafter arise with respect to the Agreement.

6.11 Modification; Waiver. No modification or amendment to this Agreement, nor any waiver of any rights, will be effective unless assented to in writing by the party to be charged, and the waiver of any breach or default will not constitute a waiver of any other right hereunder or any subsequent breach or default.

6.12 Construction; Language. Any rule of construction to the effect that ambiguities are to be resolved against the drafting party will not be applied in the construction or interpretation of this Agreement. As used in this Agreement, the words “include” and “including” and variations thereof, will not be deemed to be terms of limitation, but rather will be deemed to be followed by the words “without limitation.” The headings in this Agreement will not be referred to in connection with the construction or interpretation of this Agreement. This Agreement is in the English language only, which language shall be controlling in all respects, and all notices under this Agreement shall be in the English language.

6.13 Patent Marking. Licensee agrees to mark all Licensed Products in a manner consistent with the relevant statutes for giving appropriate patent notice. Where marking is to be performed but Licensed Products cannot be marked, the patent notice shall be placed on associated tags, labels, packaging, or accompanying documentation, either electronic or paper, as appropriate.

6.14 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 executed by facsimile signatures or other electronic means and such signatures shall be deemed to bind each party as if they were original signatures.

EXHIBIT A

BT plc Policy for Licensing Certain Patents Relating to SIP Trunking

BT plc (“BT”) has adopted a policy that governs licenses, releases and/or covenants not to sue with respect to the certain issued patents and pending patent applications owned by BT plc that relate to SIP trunking.

BT’s settlement policy is as follows:

  1. BT is willing to offer any prospective Licensee the opportunity to enter into a variety of settlements with respect to: (i) the actual BT Patents asserted as being infringed “Asserted BT Patents”); (ii) with respect to the Asserted BT Patents and certain other patents owned by BT; and (iii) with respect to the Asserted BT Patents and all other patents owned by BT with respect to which it is entitled to grant such rights. A prospective Licensee’s choice of scope (i.e., whether such Licensee wants to enter into a 1(i), 1(ii) or 1(iii) settlement) will impact the pricing of any such proposed settlement and 1(ii) and 1(iii) settlements will result in progressive increases in pricing from 1(i) (or patent in suit only) settlements.
  1. Each potential Licensee with respect to any of the BT Patents is categorized (based on a variety of factors) including, for example: (i) BT’s understanding of the acts of infringement; (ii) the implicated revenues; (iii) the timing of any such license; (iv) which BT Patents are covered by the proposed settlement; and (v) the terms and conditions contained in the proposed license agreement.
  1. BT reserves the right to adjust terms and/or accept alternate consideration based a variety of factors including, without limitation: (i) when the settlement occurs; (ii) the time, expense and other resources devoted to the negotiation of a license; (iii) whether the license is limited to the SIP Patents asserted as being infringed in the litigation or if the proposed settlement includes rights to other BT Patents; and (iv) the financial circumstances, acts of infringement, or other factors related to any potential settling Licensee.
  1. Any settlement with respect to the BT Patents is subject to the terms of BT’s form settlement agreement (which is provided to each Licensee) and is required to include an express exclusion of any coverage for any third parties (including without limitation any third party suppliers and/or service providers of the technology and systems covered by any of the applicable the BT Patents).
