Upon written request from Array or Comdial, ePHONE shall provide to Array and Comdial either: (i) a reasonable number of samples of the Products to which the Mark is affixed, or (ii) a reasonable written description of the Services that ePHONE provides under the Mark and the manner in which the Mark is used in connection with such Services, so that Array and Comdial may monitor the quality of such Products or Services and otherwise protect and maintain Array's rights in the Mark.

The licenses granted herein are exclusive as between Array and unrelated third parties. Nonetheless, Array shall retain all rights in and to the Intellectual Property, including the right to license or assign the Intellectual Property, in whole or in part, to Comdial, to any majority owned subsidiary of Comdial, or to any successor to Comdial's business, provided that such license or assignment shall have no detrimental effect on ePHONE's rights and obligations hereunder. Notwithstanding the foregoing or anything to the contrary contained herein, neither Array nor Comdial, nor any successor or affiliate thereof, shall be entitled to use the Mark in connection with products or services that are marketed in direct competition with the Products and Services. 5 ARTICLE 4 ROYALTIES Section 4.1 Royalty Payments. In partial consideration for the licenses to Intellectual Property granted herein and for the transactions contemplated under the Strategic Alliance Agreement, ePHONE shall pay Array, or such other entity as Array may designate, a royalty equal to two percent (2%) (the "Royalty Rate") of ePHONE's Consolidated Gross Sales, as hereinafter defined. (a) The royalty amounts set forth herein shall accrue upon the recognition by ePHONE of revenues for transactions that would be included in Consolidated Gross Sales and shall be paid by ePHONE on a calendar quarterly basis. For each of the first three (3) quarters of each calendar year, such quarterly royalty amount shall be calculated at the Royalty Rate applied to Consolidated Gross Sales during such quarter, and shall be paid not later than forty-five (45) days after the end of such quarter. For the fourth quarter of each calendar year, such quarterly royalty amount shall be an amount equal to the Royalty Rate applied to Consolidated Gross Sales for the calendar year, less the quarterly royalty payment amounts made for the prior three (3) quarters of that year, and shall be paid not later than ninety (90) days after the end of such calendar year. (b) For purposes of determining the royalty to be paid by ePHONE, the term "Consolidated Gross Sales" shall mean all sales resulting from ePHONE's business activities, as reflected in ePHONE's Business Plan. (c) Each royalty payment hereunder shall be accompanied by a written report describing the calculation of such payment. Furthermore, ePHONE agrees to maintain complete and accurate records sufficient to substantiate the calculation of payments made hereunder. Array or its designee may, from time to time, inspect such records to verify the accuracy of payments made hereunder; provided, however, that ePHONE shall receive at least thirty (30) days written notice of such inspections and such inspections shall take place at ePHONE's offices during ePHONE's regular business hours. Array or its designee shall bear all costs of such inspections, unless an inspection reveals a discrepancy of more than three percent (3%) in ePHONE's favor between the royalty actually paid and the royalty that should have been paid, based on ePHONE's Consolidated Gross Sales, in which case ePHONE shall bear all costs of the inspection that revealed the discrepancy. (d) Notwithstanding the foregoing, ePHONE shall pay to Array or its designee the following minimum royalty amounts: (i) During the first year of the term of this Agreement, ePHONE shall pay a minimum annual royalty amount of $180,000 (the "First Year Minimum Royalty"). In the event Consolidated Gross Sales for the first year are less than $9,000,000, ePHONE shall pay such additional royalty amounts as shall be necessary to cause the total royalty amount paid for such year to be at least equal to the First Year Minimum Royalty. Such amounts shall be paid not later than the due date for the first quarterly royalty payment due after the close of the first year. 6 (ii) For each calendar quarter after the first year of the term of this Agreement, ePHONE shall pay a minimum quarterly royalty amount of $125,000 (the "Quarterly Minimum Royalty"). In the event Consolidated Gross Sales during any quarter are less than $6,250,000, ePHONE shall pay such additional royalty amounts as shall be necessary to cause the total royalty amount paid for such quarter to be at least equal to the Quarterly Minimum Royalty. In the event any calendar quarter shall be less than three (3) months, the Quarterly Minimum Royalty for such quarter shall be prorated on a daily or other appropriate basis. Section 4.2 Non-Payment of Royalty Amounts. In the event ePHONE is unable, after exhausting all of its consolidated cash and cash equivalent assets, to pay Array or its designee the full amount of any royalty payment at the time the payment is due, the following provisions shall be applicable. (a) ePHONE shall give Array or its designee notice of ePHONE's inability to pay any portion of any royalty payment, which notice shall be accompanied by a written statement by ePHONE's principal lenders and credit facilities confirming ePHONE's inability to make such payment and the fact that ePHONE has exhausted all of its consolidated cash and cash equivalent assets. (b) The total unpaid amount of any royalty payment (the "Delinquent Payment") shall accrue interest at the annual rate of ten percent (10%) during the first year after the Delinquent Payment was due. For each three (3) month period thereafter, for so long as any portion of the Delinquent Payment remains unpaid, the interest rate applicable to the Delinquent Payment will increase by one (1) percentage point for each such three (3) month period. (c) In its sole discretion, Array or its designee may elect to accept ePHONE stock in lieu of the Delinquent Payment and accrued interest thereon. If Array or its designee exercises this option, Array or its designee shall be entitled to receive an amount of ePHONE stock equivalent in value to the Delinquent Payment, calculated at a twenty percent (20%) discount from the average of the closing prices of such stock on the five (5) trading days prior to the date on which Array or its designee elects to exercise this option. The equivalent value so determined may be paid to Array or its designee either in ePHONE common stock or in warrants for the purchase of ePHONE common stock, the terms of which are reasonably satisfactory to Array or its designee, and which provide for an exercise price of not more than one cent ($0.01) per share. ePHONE agrees to provide Array or its designee demand and piggy back registration rights for registration on an established stock exchange or on the Nasdaq national market for its shares, or for the warrants and the warrant shares to be issued upon exercise of the warrants, and to assist in the registration process. Array shall have at least two (2) demand registration rights for each year so long as any of such shares, or such warrants or warrant shares, remain unregistered. Within sixty (60) days after the Closing Date, as defined in the Strategic Alliance Agreement, the parties agree to negotiate in good faith to execute a registration rights agreement with terms and conditions that are consistent with the terms of this Agreement and that are customary and usual with respect to such agreements. 7 (d) Notwithstanding any of the provisions of this Agreement, in the event any royalty payment or portion thereof remains unpaid for one (1) year, or Array or its designee accept warrants for such payment and the warrants are not registered within such year, then ePHONE's license to the Intellectual Property shall no longer be exclusive and Array shall be entitled to license the Intellectual Property to third parties other than ePHONE. ARTICLE 5 OWNERSHIP AND PROTECTION OF INTELLECTUAL PROPERTY Section 5.1 Ownership. Nothing in this Agreement or in ePHONE's use of the Intellectual Property shall grant ePHONE any rights in or to the Intellectual Property other than the rights expressly licensed hereunder. ePHONE acknowledges Array's rights in the Intellectual Property. ePHONE shall not commit, or cause any third party to commit, any act challenging, contesting, or in any way impairing or attempting to impair Array's rights in and to the Intellectual Property. Section 5.2 Infringement by Third Parties. If ePHONE learns of any activity by a third party that might constitute infringement of Array's rights in any of the Intellectual Property, or if any third party asserts that ePHONE's use of the Intellectual Property constitutes unauthorized use or infringement, ePHONE shall so notify Array. Any action or litigation resulting from any claim of infringement arising hereunder shall be handled by Array or Comdial. ePHONE shall make all reasonable efforts to assist Array or Comdial with any such action or litigation, including providing such evidence and expert assistance as ePHONE may have within its control. Section 5.3 Rights in Improvements, Developments, Enhancements, Modifications, and Inventions. (a) CTVoice Release 2A. Within thirty (30) days following the Effective Date, ePHONE shall deliver to Array the source code for the product CTVoice Release 2A, which product shall have the same functionality and all of the capabilities of the product Array Series 3000. Array, or such other entity as Array may designate, shall own all rights in such source code, including without limitation all intellectual property rights. The source code shall be included within the definition of Intellectual Property for purposes of this Agreement, and it shall be licensed to ePHONE pursuant to the terms and conditions hereunder. 8 (i) Until the first anniversary of the Effective Date, ePHONE shall provide to Array or its designee any improvements, developments, enhancements, modifications, or inventions that resolve any functional problems or other technological difficulties with the CTVoice Release 2A product ("Bug Fixes"). ePHONE shall own all rights in the Bug Fixes, including without limitation all intellectual property rights. Nonetheless, by providing Array or its designee with the Bug Fixes, ePHONE shall be deemed to have granted Array or its designee, and such parties' successors and affiliates, a nonexclusive, irrevocable, royalty free license to the Bug Fixes. (ii) After the first anniversary of the Effective Date, ePHONE and Array or its designee agree to negotiate in good faith regarding the terms and conditions under which any Bug Fixes developed, invented, or created by employees or agents of ePHONE after the first anniversary of the Effective Date may be licensed to Array or its designee. ePHONE shall charge Array or its designee rates at least as low as the lowest rates charged to third parties not affiliated with ePHONE for such licenses. (b) Improvements, Developments, Enhancements, Modifications, and Inventions other than CTVoice Release 2A. (i) If any of the employees or agents of ePHONE improves, develops, enhances, modifies, or invents technology, works, or other intangible property, related to or arising from the Intellectual Property licensed hereunder, ePHONE shall own all rights in such technology, works, or other intangible property, including without limitation all intellectual property rights. (ii) If any of the employees or agents of Array or Comdial improves, develops, enhances, modifies, or invents technology, works, or other intangible property, related to or arising from the Intellectual Property licensed hereunder, Array or Comdial, as appropriate, shall own all rights in such technology, works, or other intangible property, including without limitation all intellectual property rights. (iii) The parties agree to negotiate in good faith regarding the terms and conditions under which any improvements, developments, enhancements, modifications, or inventions encompassed by this Section 5.3(b) may be licensed to the other parties. The parties shall charge rates at least as low as the lowest rates charged by the parties to unaffiliated third parties for such licenses. 9 ARTICLE 6 WARRANTIES, DISCLAIMERS, INDEMNIFICATION, AND LIMITATION OF LIABILITY Section 6.1 Warranties. ePHONE represents and warrants that it shall use the Intellectual Property only in accordance with the terms and conditions of this Agreement.
