---

such delay or failure.

25.0 SEVERABILITY

25.1 If any section, or clause thereof, in this Agreement is held to be unenforceable, then the meaning of such section or
clause will be construed so as to render it enforceable, to the extent feasible; and if no such interpretation would save such section or clause, it will be severed from this Agreement and the remainder will remain in full force and effect. However,
in the event such section or clause is considered an essential element of this Agreement by either Avaya or Distributor, the parties shall promptly negotiate a replacement therefore.

26.0 ASSIGNMENT

26.1 Distributor acknowledges that Avaya has appointed it as a Distributor in reliance upon the qualifications, business
reputation and financial soundness of itself and its controlling persons and management. Distributor shall not assign any right or interest under this Agreement without the prior written consent of Avaya. Any assignment or delegation by Distributor
without such consent shall be void and ineffective.

26.2 Avaya shall have the right to assign this Agreement
and to assign its rights and delegate its obligations and liabilities under this Agreement, either in whole or in part (an Assignment), to any entity that is, or that was immediately preceding such Assignment, a current subsidiary,

28.0 CHOICE OF LAW; EXCLUSIVE JURISDICTION; WAIVER OF JURY TRAIL.

28.1 This Agreement shall be governed by and construed in accordance with the laws of the State of New York, USA,
excluding its choice of law principles.

28.2 Any suit or other action arising out of this Agreement, whether
commenced in conformity with or contrary to this Agreement, shall only be brought in the federal or state courts of the State of New York, with the sole exception that any party may commence a suit in any jurisdiction to enforce an arbitration award
or judgment obtained pursuant to Section 18. In the event of any suit in the federal or state courts of the State of New York, (a) the parties hereby consent to personal jurisdiction therefore and waive any defense based on a lack of
personal jurisdiction, improper venue, or the inconvenience of the forum, (b) the parties agree that delivery of any process in the manner provided for in this Section 28.2 shall constitute lawful and valid service of process, and
(c) THE PARTIES HEREBY WAIVE TRIAL BY JURY.

conducted at Avayas offices at 211 Mt. Airy Road, Basking Ridge, New Jersey unless otherwise agreed by the parties. Any ruling by the arbitrator shall be final and binding on the parties and may be entered in any court of competent
jurisdiction. The arbitrator shall have no authority to modify or expand this Agreement or any of the provisions of this Agreement. The arbitrator is specifically authorized to render partial or summary judgment. Subject to the provisions of
Section 29.3, each party will bear its own attorneys fees associated with the arbitration, and each party shall bear an equal share of all fees, costs and expenses of the arbitrator. The arbitration proceeding and all testimony, filings,
documents, and other information produced or given in connection with the arbitration shall be treated as Confidential Information, except as may be necessary to enter any arbitration ruling in a court of competent jurisdiction or as otherwise may
be required by law.

29.2 Nothing in the Agreement shall preclude either party from specific performance or
other equitable relief, including but not limited to temporary restraining orders and preliminary injunctions, from any court of competent jurisdiction, in order to protect its rights or prevent harm pending the obtaining of an arbitration ruling,
nor shall anything herein prevent Avaya from seeking monetary damages from any court of competent jurisdiction for monies owed to it hereunder. Without limiting the foregoing



---

provisions of this Section, Distributor acknowledges that remedies at law including by means of an arbitration for a breach or threatened breach of any of the covenants contained in Sections 4.2,
14.1, and 17.0, will be inadequate and in the event of a breach or threatened breach of any such covenants, Avaya shall be entitled to an injunction specifically enforcing Distributors compliance with such covenants.

29.3 The prevailing party in any dispute relating to this Agreement resulting in a final judgment by any court or
arbitration panel, including but not limited to actions to collect money owed to Avaya by Distributor, shall be entitled to the payment of all attorneys fees and costs incurred (including all fees, costs and expenses of an arbitration).
