     1.4 Purchase Price. As consideration for the sale of the Assets to the Purchaser:

          (a) at the Closing, the Purchaser shall pay to the Seller (by wire transfer pursuant to wire transfer instructions to be provided by the Seller at least two (2) business days prior to the Closing) a total of $244,000 (the “Initial Consideration”);

          (ii) the Liabilities specifically identified on Schedule 1.5(a)(ii);

     1.6 Third Party Consents. Notwithstanding the foregoing, nothing in this Agreement shall be construed as an attempt by the Seller to assign any Transferred Contract to the extent that such Transferred Contract is not assignable without the necessary consent, authorization or approval of the other party or parties thereto. From and after the date hereof (including after the Closing), the Purchaser and the Seller each agree to use good faith efforts, and to cooperate with each other, to obtain any such consent, authorization or approval necessary to transfer any Transferred Contract. Additionally, the Seller shall take or cause to be taken such actions in its name or otherwise as the Seller may reasonably determine so as to provide the Purchaser with the benefits of the Transferred Contracts and to effect collection of money or

other consideration that becomes due and payable under such Transferred Contracts. The Seller shall not be required to pay any compensation or other consideration, or incur any expenses, in connection therewith. Following the Closing, pending or in the absence of any such consent, authorization or approval, the Purchaser and the Seller shall cooperate with each other in any reasonable and lawful arrangements to provide to the Purchaser the benefits of use of any Transferred Contract that is not assignable to the Purchaser. At such time that any such consent, authorization or approval has been obtained, the Seller shall provide the Purchaser with a copy thereof, and thereafter, the Transferred Contract associated with such consent or approval shall be assigned or transferred to the Purchaser automatically without any other conveyance or other action by the parties.

     1.7 Sales Taxes. The Purchaser shall bear and pay, and shall reimburse the Seller and the Seller’s affiliates for, any sales taxes, use taxes, transfer taxes, documentary charges, recording fees, or similar taxes, charges, fees, or expenses that may become payable in connection with the sale of the Assets to the Purchaser or in connection with any of the other Transactions.

     1.8 Allocation. Prior to, and as a condition of, the Closing, the Purchaser and the Seller shall agree to a schedule which shall set forth the allocation of the Purchase Price among the classes of the Assets (for example, tangible assets, intangible assets, goodwill, Contracts) (the “High Level Allocation”). Within sixty (60) days following the Closing Date, the parties shall use their good faith, commercially reasonable efforts to agree to an allocation of the Purchase Price among the various assets within each of the classes of the Assets (the “Detailed Allocation”). If and to the extent the Purchaser and the Seller agree to a Detailed Allocation, (a) such Detailed Allocation shall be binding on the parties, (b) the parties shall prepare and timely file all applicable federal and state income and sales Tax forms in a manner consistent with such Detailed Allocation, and (c) except as otherwise required pursuant to the Code, neither party shall take a position inconsistent with the Detailed Allocation on any Tax Return, or otherwise. If the parties are unable to reach a timely agreement regarding the Detailed Allocation, each party shall be entitled to adopt its own position regarding the allocation of the Purchase Price among the various assets within each of the classes of Assets, provided that in such case any detailed allocation must in any event be consistent with the High Level Allocation, and except as otherwise required pursuant to the Code, neither of the parties shall take a position inconsistent with the High Level Allocation on any Tax Return, or otherwise.

For purposes of this Agreement, “Closing Date” shall mean the time and date as of which the Closing actually takes place.

          (b) At the Closing:

          (a) Within forty-five (45) days after the end of each twelve (12) month period ending on the first, second and third annual anniversaries of the Closing Date, the Purchaser shall provide to the Seller a written report setting forth in reasonable detail the total amount of Qualifying Sales, if any, for such twelve (12) month period and the amount of any Royalty Payment due to the Seller for such twelve (12) month period with respect to such Qualifying Sales. Each such report shall be accompanied by payment in the amount of any Royalty Payment due to the Seller for the twelve (12) month period to which the report relates.

          (b) The Purchaser shall maintain accurate and complete books and records of all information necessary for the computation of Qualifying Sales and any Royalty Payment

payable hereunder for a period of not less than eighteen (18) months after the end of the twelve (12) month period to which they relate.

          (c) Upon reasonable prior written notice to the Purchaser, the Seller shall have the right at any time (but no more often than twice in any twelve (12) month period and in any event not later than eighteen (18) months after the end of the twelve (12) month period to which the proposed audit relates) to have an audit performed of the books of account and other records of the Purchaser during normal business hours for the sole purpose of verifying the calculation of Qualifying Sales and Royalty Payments to be made hereunder. The fees and expenses of any such audit shall be borne by the Seller, except in the event that the audit reveals an underpayment of more than five percent (5%) of the actual amount determined to be due, whereupon such fees and expenses shall be borne by the Purchaser. To the extent that such audit indicates that there has been an underpayment of Royalty Payments, the Purchaser shall, within thirty (30) days of the delivery of the results of such audit, provide for payment of the amounts which were underpaid, unless a bona fide dispute exists as to the results of such audit, together with interest thereon at the “prime rate” of interest prevailing from time to time after the original due date for such unpaid amount. The “prime rate” shall mean, on a particular date, a rate per annum equal to the rate of interest published in The Wall Street Journal as the “prime rate”, as in effect on such day, with any change in the prime rate resulting from a change in said prime rate to be effective as of the date of the relevant change in said prime rate. In the event that The Wall Street Journal should cease or temporarily interrupt publication, then the “prime rate” shall mean the daily average prime rate published in another business newspaper, or business section of a newspaper, of national standing chosen by the Purchaser and the Seller. If The Wall Street Journal resumes publication, the substitute index will immediately be replaced by the prime rate published in The Wall Street Journal.

          (d) Notwithstanding anything contained in this Agreement to the contrary, the Seller acknowledges and agrees that the Purchaser’s obligation to pay Royalty Payments shall terminate on the occurrence of an event and to the extent specified in Section 10 of the Noncompetition Agreement.

The withholding and deduction of any such sum shall operate for all purposes as a complete discharge (to the extent of such sum) of the obligation to pay the amount from which such sum was withheld and deducted.

     9.5 Provisions Regarding Indemnity.

          (a) The indemnified party (or parties) shall promptly notify the indemnifying party (or parties) of any third-party claim, demand, action or proceeding for which indemnification will or may be sought under Sections 9.2 or 9.3 (a “Third Party Claim”), but in no event later than ten (10) business days after receiving notice of such Third Party Claim; provided, however, that the failure to so notify the indemnifying party will not relieve the indemnifying party from liability hereunder in respect of such claim except to the extent the indemnifying party is prejudiced as a result of such failure, including where failure results in losses to the indemnifying party or the forfeiture of substantive rights or defenses that would otherwise be available in the defense of such claim. Such notice shall specify facts reasonably known to the indemnified party (or parties) giving rise to such indemnity rights. The indemnifying party will have the right, at its expense, to assume the defense thereof using counsel reasonably acceptable to the indemnified party. If the indemnifying party elects not to assume the defense or fails to notify the indemnified party within ten (10) business days after delivery of the indemnified party’s notice of such Third Party Claim, that it will assume the defense, then the indemnified party may employ counsel reasonably satisfactory to the indemnifying party to represent or defend it against any such Third Party Claim and the indemnifying party will pay the reasonable fees and disbursements of such counsel; provided, however, that the indemnifying party shall not, in connection with any legal proceeding or any separate but substantially similar legal proceedings arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm of attorneys at any time for all indemnified persons, except to the extent that local counsel, in addition to its regular counsel, is required in order to effectively defend against such legal proceeding. If the indemnifying party does assume the defense of such Third Party Claim, the indemnifying party shall have no obligation in respect of the indemnified party’s expenses; provided, that the indemnified party shall have the right to participate in, at its own expense, but not control, the defense of any such

Third Party Claim. In connection with any Third Party Claim, the Parties shall cooperate with each other in good faith in such manner to preserve in full (to the extent possible) the confidentiality of all business records and the attorney-client work-product and any other potentially applicable privileges and to render each other assistance as they may reasonably require. No Third Party Claim shall be settled (i) without the prior written consent of the indemnifying party and (ii) without the prior written consent of the indemnified party unless such settlement provides for no relief other than the payment of monetary damages for which the relevant indemnified parties will be indemnified in full.

          (b) As soon as reasonably practicable after becoming aware of a direct claim for indemnification under Section 9.2 or 9.3 other than a Third Party Claim (a “Direct Claim”), the indemnified party (or parties) agrees to give a Claim Notice to the indemnifying party (or parties) providing indemnification under this Section 9, as applicable, of such Direct Claim; provided, however, that the failure to so notify the indemnifying party will not relieve the indemnifying party from liability hereunder in respect of such claim except to the extent the indemnifying party is prejudiced as a result of such failure. If the indemnified party is the Purchaser or the Company and is seeking to enforce such claim pursuant to the Escrow Agreement, the indemnifying party shall deliver a copy of the Claim Notice to the Escrow Agent.

               (i) Within twenty (20) days after receipt by the indemnifying party of a Claim Notice, the indemnifying party may deliver to the indemnified party a written response (the “Response Notice”) in which the indemnifying party: (A) agrees that the full Claimed Amount (the “Full Amount”) is owed to the indemnified party (in which case the Response Notice shall be accompanied by a payment by the indemnifying party to the indemnified party of the Claimed Amount, by check or by wire transfer; provided, that if the indemnified party is the Purchaser or the Company and is seeking to enforce such claim pursuant to the Escrow Agreement, the indemnifying party shall also deliver a copy of the Response Notice to the Escrow Agent and instruct the Escrow Agent to disburse the Full Amount to the indemnified party); (B) agrees that part, but not all, of the Claimed Amount (the “Agreed Amount”) is owed to the indemnified party (in which case the Response Notice shall be accompanied by a payment by the indemnifying party to the indemnified party of the Agreed Amount, by check or by wire transfer; provided, that if the indemnified party is the Purchaser or the Company and is seeking to enforce such claim pursuant to the Escrow Agreement, the indemnifying party shall also deliver a copy of the Response Notice to the Escrow Agent and instruct the Escrow Agent to disburse the Agreed Amount to the indemnified party); or (C) indicates that no part of the Claimed Amount is owed to the indemnified party. Any part of the Claimed Amount that is not agreed to be released to the indemnified party pursuant to the Response Notice shall be the “Contested Amount.” If the Response Notice is not received by the indemnified party within such 20-day period, then the indemnifying party shall be conclusively deemed to have agreed that the Full Amount is owed to the indemnified party.

               (ii) If the indemnifying party delivers a Response Notice indicating that there is a Contested Amount, the indemnifying party and the indemnified party shall attempt in good faith to resolve the dispute related to the Contested Amount. If the indemnified party and the indemnifying party resolve such dispute, such resolution shall be binding on the indemnifying party and the indemnified party, and if the indemnified party is the Purchaser or

the Company, a settlement agreement shall be signed by the indemnified party and the indemnifying party and sent to the Escrow Agent.

To the extent that the Company offers voice-over IP terminals (“soft phones”) to its M6 customers generally, the Company agrees to provide to the Seller (and to repair or replace the same when applicable) such soft phones, including all necessary software licenses and software upgrades (minor and major) also made available to M6 customers generally, as the Seller may request from time to time, at a cost equal to the Company’s documented out-of-pocket third party costs incurred in providing such soft phones and software licenses. The Company grants to the Seller, at no charge to the Seller, a license and right to use the Seller M6 Products provided hereunder with all such M6 soft phones. If the Company discontinues supporting M6 Products, they will replace, and provide the Seller with, other products sold by the Company that have similar functionalities. This Section 10.6 will terminate on the third anniversary of the Closing Date.
