Notwithstanding anything to the contrary in this Section 2.1(n), nothing set forth in Section 2.2(n) as an “Excluded Asset” shall be a Purchased Asset. Notwithstanding the foregoing, if after the date hereof a party identifies, becomes aware of, or enters into a Contract that would qualify as a Purchased Asset (and is not expressly listed as an Excluded Asset on a Schedule hereto), and is not expressly listed as a Purchased Contract on a Schedule hereto, then (a) such party will promptly notify the other party of such Contract, (ii) Seller will promptly provide Purchaser with a complete and accurate copy of such Contract (including all amendments, waivers and similar matters) and all information Purchaser may reasonably request regarding such Contract (including details of any associated Liabilities), and (iii) Purchaser may elect to unilaterally amend Schedule 1.1(c) to add such Contract as a Purchased Contract by giving Seller written notice of such amendment (notwithstanding anything to the contrary in Section 12.4).

16 2.3 Assumption of Liabilities. On the terms and subject to the conditions set forth in this Agreement, at the Closing Purchaser shall (or shall cause its designated Affiliate or Affiliates to) assume, effective as of the Closing, all of the following Liabilities of Seller and the Selling Subsidiaries (collectively, the “Assumed Liabilities”): (a) all Liabilities of Seller and the Selling Subsidiaries under the Purchased Contracts (i) that arise out of or relate to events, circumstances, conditions, or actions that first occur during the period from and after the Closing Date or (ii) for services to be rendered by the Business with respect to Deferred Revenue; and (b) all liabilities and obligations relating to (i) employee compensation or other arrangements with respect to any Transferred Employee arising on or after the Closing, and (ii) employee benefits, including, without limitation, all entitlements, vacation, and years of service, whether accrued as of the Closing Date or arising out of or related to the period from and after the Closing Date (all such Liabilities to the extent relating to a period on or before the Closing, the “Transferred Employee Liabilities”), provided, however, with respect to the Transferred Employee Liabilities related to paid time off, solely to the extent such liabilities in the aggregate are less than or equal to Four Hundred Fifty Thousand Dollars ($450,000); and to the extent the Transferred Employee Liabilities related to paid time off in the aggregate exceed such amount, such excess will be an Excluded Liability. 2.4 Excluded Liabilities. Notwithstanding any other provision of this Agreement (or any agreement or instrument contemplated hereby) to the contrary, Purchaser (and its designated Affiliates, as applicable) is assuming only the Assumed Liabilities and is not assuming the Excluded Liabilities or any other Liability, Legal Proceeding against or obligation of Seller or the Subsidiaries or any other Person of whatever nature, whether presently in existence or arising hereafter, and Purchaser (and its Affiliates) will not assume and will not be responsible to pay, perform or discharge any Liabilities of Seller, any of the Subsidiaries, or the Business or relating to the Purchased Assets of any kind or nature whatsoever (including the Excluded Liabilities) other than the Assumed Liabilities. Purchaser (and its Affiliates) will not assume or be liable for any Excluded Liabilities. Seller shall, and shall cause the Subsidiaries to, timely perform, satisfy and discharge in accordance with their respective terms all Excluded Liabilities. “Excluded Liabilities” shall mean all Liabilities of Seller and the Subsidiaries arising out of, relating to or otherwise in respect of the Business or the Purchased Assets on or before the Closing Date and all other Liabilities of Seller and the Subsidiaries other than the Assumed Liabilities, including the following Liabilities: (a) all Liabilities in respect of any products sold and/or services performed by Seller or the Subsidiaries on or before the Closing Date, other than Liabilities expressly included in Section 2.3(a); (b) all Current Liabilities, except to the extent specifically set forth in Section 2.3; (c) all Environmental Costs and Liabilities, to the extent arising out of or otherwise related to the ownership or operation by Seller or the Subsidiaries of the Real Property Lease (or any condition thereon) or the Business, in each case, on or prior to the Closing Date;

(b) From time to time following the Closing, Seller and Purchaser shall, and shall cause their respective Affiliates to, execute, acknowledge and deliver all such further conveyances, notices, assumptions, releases and acquittances and such other instruments, and shall take such further actions, as may be necessary or appropriate to assure fully to Purchaser, its designated Affiliates and their respective successors or assigns, all of the properties, rights, titles, interests, estates, remedies, powers and privileges intended to be conveyed to Purchaser or its designated Affiliates under this Agreement and the Seller Documents and to assure fully to Seller and its Affiliates and their successors and assigns, the assumption of the liabilities and obligations intended to be assumed by Purchaser or its designated Affiliates under this Agreement and the Seller Documents, and to otherwise make effective the transactions contemplated hereby and thereby. (c) Nothing in this Agreement nor the consummation of the transactions contemplated hereby shall be construed as an attempt or agreement to assign any Purchased Asset, including any Contract, Permit, certificate, approval, authorization or other right, which by its terms or by Law is nonassignable without the consent of a third party or a Governmental Body or is cancelable by a third party in the event of an assignment (or such assignment would be in breach of, or result in a default under, such Contract) (“Nonassignable Assets”) unless and until such consent shall have been obtained. Seller shall, and shall cause its Affiliates to, use its best efforts to cooperate with Purchaser and its designated Affiliates at their request in endeavoring to obtain such consents promptly. To the extent permitted by applicable Law, in the event consents to the

19 assignment thereof cannot be obtained, such Nonassignable Assets shall be held, as of and from the Closing Date, by Seller or the applicable Affiliate of Seller in trust for Purchaser or its designated Affiliates and the covenants and obligations thereunder shall be performed by Purchaser in Seller’s or such Affiliate’s name and all benefits and obligations existing thereunder shall be for Purchaser or its designated Affiliates’ account. Seller shall take or cause to be taken at Seller’s expense such actions in its name or otherwise as Purchaser or its designated Affiliates may reasonably request so as to provide Purchaser and its designated Affiliates with the benefits of the Nonassignable Assets and to effect collection of money or other consideration that becomes due and payable under the Nonassignable Assets, and Seller or the applicable Affiliate of Seller shall promptly pay over to Purchaser and its designated Affiliates all money or other consideration received by it in respect of all Nonassignable Assets. As of and from the Closing Date, Seller on behalf of itself and its Affiliates authorizes Purchaser, to the extent permitted by applicable Law and the terms of the Nonassignable Assets, at Purchaser’s expense, to perform all the obligations and receive all the benefits of Seller or its Affiliates under the Nonassignable Assets and appoints Purchaser its attorney-in-fact to act in its name on its behalf or in the name of the applicable Affiliate of Seller and on such Xxxxxxxxx’s behalf with respect thereto. Seller will, and will cause its Affiliates to, reasonably cooperate with any reasonable requests by Purchaser and its designated Affiliates to effect the foregoing provisions, including by entering into such further agreements and instruments with Purchaser and its designated Affiliates (such as subcontracting, sub- licensing, sub-leasing and similar arrangements) as may be necessary or desirable in connection therewith. 2.6 Bulk-Sales Laws. The parties hereby waive compliance with the requirements and provisions of any “bulk-transfer” Laws of any jurisdiction that may otherwise be applicable with respect to the sale of any or all of the Purchased Assets to Purchaser; provided, however, that the Seller agrees (i) to pay and discharge when due or to contest or litigate all claims of creditors which are asserted against Purchaser or the Purchased Assets by reason of such noncompliance, (ii) to indemnify, defend and hold harmless Purchaser from and against any and all such claims in the manner provided in Article XI and (iii) to take promptly all necessary action to remove any Lien which is placed on the Purchased Assets by reason of such noncompliance. Any “bulk-transfer” Law that addresses Taxes shall be governed by Article XI and not by this Section 2.6. 2.7 Purchase Price Allocation. Not later than ninety days after the Closing Date, Purchaser shall prepare and deliver to Seller a copy of Form 8594 and any required exhibits thereto (the “Asset Acquisition Statement”) allocating the Total Consideration among the Purchased Assets in accordance with Section 1060 of the Code (and applicable regulations) and Schedule 2.7. Purchaser shall prepare and deliver to Seller from time-to-time revised copies of the Asset Acquisition Statement in accordance with Schedule 2.7 (the “Revised Statements”) so as to report any matters on the Asset Acquisition Statement that need updating (including purchase price adjustments, if any), provided that the value attributed to the elements transferred in the context of the local transfer agreement set out in Section 9.1(v) shall not be lower than the price set out therein. The Asset Acquisition Statement or any Revised Statement, as the case may be, shall be deemed final unless Seller notifies Purchaser in writing that Seller objects to one or more items reflected in such statement withing thirty (30) days after delivery of the same to Seller. In the event of any such objection, Purchaser and Seller shall negotiate in good faith to resolve the dispute. The Total Consideration paid by Purchaser for the Purchased Assets shall be allocated in accordance with the Asset Acquisition Statement or, if applicable, the last Revised Statements,

20 provided by Purchaser to Seller, and all income Tax Returns and reports filed by Purchaser and Seller shall be prepared consistently with such allocation. Seller shall be kept reasonably apprised of the draft allocations and Purchaser shall reasonably cooperate with Seller with respect to such allocations so as to minimize Taxes payable by Seller to the extent legally permissible, it being understood and agreed that it shall be reasonable for Purchaser to refuse to make any allocation requested by Seller to the extent that such allocation would in any way be detrimental to Purchaser, financially or otherwise. 2.8 Right to Control Payment. Purchaser shall have the right, but not the obligation, to make any payment due from Seller or the Subsidiaries with respect to any Excluded Liabilities which are not paid by Seller or the Subsidiaries within ten Business Days following written request for payment from Purchaser; provided, however, that if Seller or the Subsidiaries advise Purchaser in writing during such ten Business Day period that a good faith payment dispute exists or Seller or the Subsidiaries have valid defenses to non-payment with respect to such Excluded Liability, then Purchaser shall not have the right to pay such Excluded Liability. Seller and the Subsidiaries agree to reimburse Purchaser promptly and in any event within ten Business Days following written notice of such payment by Purchaser for the amount of any payment made by Purchaser pursuant to this Section 2.8. Upon Purchaser’s request, Seller and the Subsidiaries will promptly affirm in writing to the relevant counterparty that any Excluded Liability is the sole responsibility of Seller or the relevant Subsidiary and that Purchaser did not assume such Excluded Liability in this transaction or otherwise. 2.9 Proration of Certain Expenses. Subject to Section 11.2 with respect to Taxes, all rents and other payments (including utilities and any prepaid amounts) due under the Real Property Lease and any other leases constituting part of the Purchased Assets shall be prorated between Seller and the Selling Subsidiaries, on the one hand, and Purchaser and its designated Affiliates, on the other hand, as of the Closing Date. Seller shall be responsible for all rents (including any percentage rent, additional rent and any accrued tax and operating expense reimbursements and escalations), charges and other payments of any kind accruing during any period under the Real Property Lease or any such other leases up to and including the Closing Date. Purchaser or its designated Affiliates shall be responsible for all such rents, charges and other payments accruing during any period under the Real Property Lease or any such other leases after the Closing Date. Purchaser or its designated Affiliates shall pay the full amount of any invoices received by it and shall submit a request for reimbursement to Seller for Seller’s share of such expenses and Seller shall pay the full amount of any invoices received by it and Purchaser or its designated Affiliates shall reimburse Seller for Purchaser’s share of such expenses. Each such reimbursements shall be paid no later than 15 days after the responsible party’s receipt of notice requesting such reimbursement with reasonable and appropriate evidence of the basis for such request (including reasonable documentation showing payment by the requesting party). 2.10 Receivables; Misallocation. (a) Each party shall provide reasonable assistance to the other in the collection of accounts receivable. If Seller or any of the Subsidiaries shall receive payment in respect of accounts receivable that are included in the Purchased Assets, then Seller shall promptly forward such payment to Purchaser. If Purchaser shall receive payment in respect of accounts receivable

21 that are included in the Excluded Assets, then Purchaser shall promptly forward such payment to Seller. (b) If after the Closing (i) Purchaser or any of its Subsidiaries holds any Excluded Assets or Excluded Liabilities or (ii) Seller or any Subsidiary holds any Purchased Assets or Assumed Liabilities, Purchaser and Seller will, and will cause the applicable Subsidiary to, promptly execute such documents as may be reasonably necessary to cause the transfer of and thereafter transfer (or cause to be transferred) such assets or assume (or cause to be assumed) such Liabilities to or from (as the case may be) the other party for no additional consideration. Prior to any such transfer, the Person receiving or possessing any such asset will hold it in trust for the benefit of such other party. If, following the Closing, Seller or the Subsidiaries receive any payments in respect of the Purchased Assets, such Seller will, and will cause such Subsidiary, shall promptly remit such payments to Purchaser or other entity designated by Purchaser. If, following the Closing, Purchaser receives any payments in respect of the Excluded Assets, Purchaser shall promptly remit such payments to Seller or any other Person designated by Seller. 2.11 Withholding. Notwithstanding any other provision in this Agreement, Purchaser and its designated Affiliates and any other applicable withholding agent shall be entitled to deduct and withhold from the payments to be made pursuant to this Agreement any Taxes required to be deducted and withheld with respect to the making of such payments under applicable Law; provided that (a) the Person making any payment shall use commercially reasonable efforts to notify the Person entitled to receive such payment at least two business days before any such payment is made of any deduction or withholding requirement applicable to such payment of which the withholding Person becomes aware and (b) the parties shall use commercially reasonable efforts to cooperate prior to the payment date to reduce or eliminate any such deduction and withholding to the extent permitted by applicable Law. To the extent that amounts are so withheld and deducted, such amounts will be remitted to the applicable Taxing Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to such Person in respect of which such deduction or withholding was made. ARTICLE III CONSIDERATION 3.1 Consideration. The aggregate consideration for the Purchased Assets shall be (a) an amount in cash equal to Thirty-Four Million Dollars ($34,000,000.00) (the “Purchase Price”), and (b) the assumption of the Assumed Liabilities (together with the Purchase Price, the “Total Consideration”). 3.2 Payment of Purchase Price. (a) On the Closing Date, Purchaser shall pay to Seller an amount equal to Thirty Million Dollars ($30,000,000.00) (the “Initial Closing Payment”), which shall be paid by wire transfer of immediately available funds into the accounts designated by Seller in writing not fewer than three Business Days prior to the Closing Date. Notwithstanding the foregoing, Seller directs Purchaser to pay the applicable portion of the Initial Closing Payment to the applicable account or

22 accounts required under the EdgeCo Payoff Letter in order to release all Liens on the Purchased Assets under the EdgeCo Credit Agreement. (b) No more than twelve (12) months following the Closing Date, Purchaser shall pay to Seller an amount equal to Four Million Dollars ($4,000,000.00) (the “Guaranteed Closing Payment”), which shall be paid by wire transfer of immediately available funds into the accounts designated by Seller pursuant to Section 3.2(a), unless Seller has given written instruction to Purchaser designating different accounts no fewer than three Business Days prior to the date the Guaranteed Closing Payment is due hereunder. (c) Notwithstanding the foregoing, if either (i) the aggregate Deferred Revenue exceeds Six Million Dollars ($6,000,000.00), or (ii) the Transferred Employee Liabilities relating to paid time off exceed Four Hundred Fifty Thousand Dollars ($450,000.00) in the aggregate, then, in each case, the Guaranteed Closing Payment will be reduced dollar-for-dollar by any such excess amounts.

Seller shall use (and shall cause each of the Subsidiaries to use) its commercially reasonable efforts to obtain at the earliest practicable date all consents, waivers, approvals and notices are required to consummate, or in connection with, the transactions contemplated by this Agreement, including the consents, waivers, approvals and notices referred to in Section 5.3(b) hereof. All such consents, waivers, approvals and notices shall be in writing and in form and substance satisfactory to Purchaser, and executed counterparts of such consents, waivers and approvals shall be delivered to Purchaser promptly after receipt thereof, and copies of such notices shall be delivered to Purchaser promptly after the making thereof. Notwithstanding anything to the contrary in this Agreement, neither Purchaser nor any of its Affiliates shall be required to pay any amounts in connection with obtaining any consent, waiver or approval and Seller and the Selling Subsidiaries will not amend, waive or otherwise modify the terms of any Purchased Contract without Purchaser’s prior written consent. 7.4 Further Assurances.

(a) The Seller Parties acknowledge that they have become, and following the date of this Agreement will continue to be, familiar with Confidential Information included in the Purchased Assets. Therefore, during the period beginning on the Closing Date and ending on the third anniversary of the Closing Date, the Seller Parties shall not (and shall not take any steps to, or prepare to), and shall cause their Affiliates not to, directly or indirectly, in any capacity, engage in, (i) develop, own, manage, control or exert any influence upon, acquire, lease, consult with, render or provide advice to, operate, affiliate with, participate in, permit its name to be used in connection with, receive any economic benefit from or in any other manner engage in any other similar activity or have any financial interest in, or otherwise provide any services to or for the benefit of, the Business or any other line of business that directly or indirectly, in whole or in part, competes with the Business (the “Restricted Business”) anywhere in the world (the “Restricted Area”); provided, however, that the sale of any hardware product (but not any software product) by the Seller or any Subsidiary which enables the Business or a software product (owned and sold or licensed by an unrelated third party (and not Seller or a Subsidiary)) that is competitive to products competitive with the Business shall not be considered a Restricted Business, (ii) manage or provide management or consulting services to, or participate in the management or control of,

52 or exert any influence upon, any Person involved in the development, research, ownership or operation of any Restricted Business within the Restricted Area, or (iii) own a direct or indirect interest (financial or otherwise) in, or lend or contribute money to, or otherwise provide financial support for, any Person that engages in a Restricted Business within the Restricted Area. Notwithstanding the foregoing, this clause (a) shall not apply to any activities performed by the Seller Parties or their Affiliates for the purpose of carrying out their obligations under the Transition Services Agreement. (b) During the period beginning on the Closing Date and ending on the second anniversary of the Closing Date, Seller and the Seller Parties shall not, and Seller shall cause its directors, officers, employees and Affiliates not to: (i) cause, solicit, induce or encourage any employee of Purchaser or its Affiliates (including the Transferred Employees) to leave their employment with Purchaser or any Affiliate of Purchaser; (ii) hire, employ or otherwise engage any such employee, unless such employee has (x) had his or her employment terminated by Purchaser or any Affiliate of Purchaser and such terminated employee has not been employed by Purchaser or an Affiliate of Purchaser for at least ninety (90) days or (y) not been employed by Purchaser or any Affiliate of Purchaser for one year prior to such hiring, employment, or other engagement; or (iii) take any action that could reasonably be expected to cause, induce or encourage any material actual or prospective client, customer, supplier or licensor of the Business (including any existing or former customer of Seller or the Selling Subsidiaries and any Person that becomes a client or customer of the Business after the Closing) or any other Person who has a material business relationship with the Business, to terminate, decrease or modify any such actual or prospective relationship. (c) (b) During the period beginning on the Closing Date and ending on the second anniversary of the Closing Date, Purchaser shall not, and Purchaser shall cause its directors, officers, employees and Affiliates not to: (i) cause, solicit, induce or encourage any DZS Employees to leave their employment with Seller or any Subsidiary, or (ii) hire, employ or otherwise engage any DZS Employee, unless such DZS Employee has (x) had their employment terminated by Seller or a Subsidiary and such terminated employee has not been employed by Seller or a Subsidiary for at least ninety (90) days or (y) not been employed by Seller or a Subsidiary for one year prior to such hiring, employment, or other engagement. (d) From and after the date hereof, neither party shall, and each shall cause its Affiliates and their respective officers, and directors not to, directly or indirectly, disclose, reveal, divulge or communicate to any Person other than authorized officers, directors and employees of the other party or use or otherwise exploit for its own benefit or for the benefit of anyone other than such party, any Confidential Information (as defined below). Neither party, nor their respective officers, directors and Affiliates, shall have any obligation to keep confidential any Confidential Information if and to the extent disclosure thereof is specifically required by law; provided, however, that in the event disclosure is required by applicable Law, such party shall, to the extent reasonably possible, provide the other party with prompt notice of such requirement prior to making any disclosure so that such party may seek an appropriate protective order. For purposes of this Section 7.5(d), “Confidential Information” means any information with respect to the business, including methods of operation, customers, customer lists, products, prices, fees, costs, Technology, inventions, Trade Secrets, know-how, Software, marketing methods, plans, personnel, suppliers, competitors, markets or other specialized information or proprietary matters

53 of either party. Confidential Information does not include, and there shall be no obligation hereunder with respect to, information that (i) is generally available to the public on the date of this Agreement or (ii) becomes generally available to the public other than as a result of a disclosure not otherwise permissible thereunder. For the avoidance of doubt, all Confidential Information that primarily relates to the Business (other than Confidential Information that primarily relates to any Excluded Assets) constitutes part of the Purchased Assets and from and after the Closing will belong to Purchaser to the extent it relates to the Business. To the extent Confidential Information relates to both the Business and other businesses of Seller or the Subsidiaries, then each party will own and have the full right to use and exploit such Confidential Information. (e) The covenants and undertakings contained in this Section 7.5 relate to matters which are of a special, unique and extraordinary character and a violation of any of the terms of this Section 7.5 will cause irreparable injury, the amount of which will be impossible to estimate or determine and which cannot be adequately compensated. Accordingly, the remedy at law for any breach of this Section 7.5 will be inadequate. Therefore, the non-breaching will be entitled to an injunction, restraining order or other equitable relief from any court of competent jurisdiction in the event of any breach of this Section 7.5 without the necessity of proving actual damages or posting any bond whatsoever. The rights and remedies provided by this Section 7.5 are cumulative and in addition to any other rights and remedies which the non-breaching party may have hereunder or at law or in equity. (f) The parties recognize that the covenants in this Section 7.5, and the territorial, time and other limitations with respect thereto, are reasonable and properly required for the adequate protection of the parties and the acquisition of the Purchased Assets by Purchaser, including the Confidential Information, and agree and acknowledge that such limitations are reasonable with respect to each party’s activities, business and public purpose. Each party acknowledges and represents that: (i) sufficient consideration has been given by each party to the other as it relates to the covenants set forth in this Section 7.5; (ii) the restrictions and agreements in this Section 7.5 are reasonable in all respects and necessary for the protection of Purchaser and its Affiliates, the Confidential Information included in the Purchased Assets and the goodwill primarily associated with the Business, and that in each case, without such protection, Purchaser’s competitive advantage would be materially adversely affected; and (iii) the agreements in this Section 7.5 are an essential inducement to Purchaser to enter into this Agreement and they are in addition to, rather than in lieu of, any similar or related covenants to which any Seller Party is party or by which it is bound. (g) The parties hereto agree that, if any court of competent jurisdiction in a final nonappealable judgment determines that a relevant feature of this Section 7.5 is unreasonable, arbitrary or against public policy, then a relevant feature which is determined by such court to be reasonable, not arbitrary and not against public policy may be enforced against the applicable party. 7.6 Preservation of Records. Each party agrees that it shall preserve and keep the records held by it or their Affiliates relating to the Business for a period of six years from the Closing Date and shall make such records and personnel available to the other as may be reasonably required by the other party in connection with, among other things, any insurance

54 claims by, legal proceedings against or governmental investigations of the applicable party or any of its Affiliates or in order to enable Seller or Purchaser to comply with their respective obligations under this Agreement and each other agreement, document or instrument contemplated hereby or thereby. In the event any Seller Party or Purchaser wishes to destroy (or permit to be destroyed) such records after that time, such party shall first give ninety days prior written notice to the other and such other party shall have the right at its option and expense, upon prior written notice given to such party within that ninety-day period, to take possession of the records within 180 days after the date of such notice. 7.7 Publicity. (a) None of the parties or their Affiliates shall issue any press release or public announcement concerning this Agreement or the transactions contemplated hereby without obtaining the prior written approval of the other party hereto, which approval will not be unreasonably withheld or delayed, unless, in the sole judgment of Purchaser or Seller, as applicable, disclosure is otherwise required by applicable Law (including in connection with enforcing the parties’ rights under this Agreement or the other documents contemplated by this Agreement) or by the applicable rules of any stock exchange on which Purchaser lists securities, provided that, to the extent required by applicable Law or by the applicable rules of any stock exchange on which Purchaser lists securities, the party intending to make such release shall use its commercially reasonable efforts consistent with such applicable Law to consult with the other party with respect to the timing and content thereof, and, unless required by applicable Law or by the applicable rules of any stock exchange on which a Party or its Affiliates lists securities, will not reference the other party or its Affiliates by name without such party’s consent (not to be unreasonably withheld, conditioned or delayed). (b) Each of the parties agrees that the terms of this Agreement shall not be disclosed or otherwise made available to the public and that copies of this Agreement shall not be publicly filed or otherwise made available to the public, except where such disclosure, availability or filing is required by applicable Law. 7.8 Notification of Certain Matters. Seller shall give notice to Purchaser and Purchaser shall give notice to Seller, as promptly as reasonably practicable upon becoming aware of (a) any fact, change, condition, circumstance, event, occurrence or non-occurrence that has caused or is reasonably likely to cause any representation or warranty in this Agreement made by it to be untrue or inaccurate in any respect at any time after the date hereof and prior to the Closing, (b) any material failure on its part to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder or (c) the institution of or the threat of institution of any Legal Proceeding against Seller or any of the Selling Subsidiaries related to this Agreement or the transactions contemplated hereby; provided that the delivery of any notice pursuant to this Section 7.8 shall not modify or otherwise qualify any representations, warranties or covenants made by any party herein or limit or otherwise affect the remedies available hereunder to the party receiving such notice, or the representations or warranties of, or the conditions to the obligations of, the parties hereto. 7.9 Spanish Tax Certificate. As soon as possible after the execution of this Agreement and, in any case, prior to Closing, the parties to this Agreement shall (or shall procure that their

55 respective Selling Subsidiaries shall) jointly request a tax certificate from the Spanish Tax authorities (at a state, regional and local level) in accordance with article 175.2 of the Spanish General Tax Law (Ley General Tributaria) regarding the existence of any pending Tax debts, sanctions or obligations in respect of the business carried out by DZS Spain. In particular, DZS Spain shall deliver to the Purchaser the necessary authorizations for the Purchaser to request the tax certificates. Seller shall deliver to Purchaser a certificate from the Spanish Social Security and the Spanish Tax Authorities (in this case, a general one, different from the one described above) confirming the absence of any pending debts, sanctions or obligations in respect of DZS Spain. If, in respect to any application for the above certificates, any Governmental Body asserts that Seller or the relevant Selling Subsidiary is liable for any Tax, Seller shall promptly pay, or shall cause to be paid, any and all such amounts and shall provide evidence to the Purchaser that such liabilities have been paid in full or otherwise satisfied (and all such Liabilities are Excluded Liabilities). 7.10 Wind-Down Trademark License. Seller hereby grants to Purchaser a worldwide, irrevocable, sublicenseable, transferable, and royalty-free license to use, for the twelve (12) month period following the Closing Date, the Seller Licensed Marks solely in a form and manner, and with standards of quality, substantially consistent with the use of the Seller Licensed Marks by the Business as of the Closing Date. Notwithstanding the foregoing, Purchaser shall have the right to use the Seller Licensed Marks at all times after the Closing (a) as required by applicable law and as may be required to perform any contractual obligations; (b) on internal business and legal documents and items; and (c) in a neutral, non-trademark manner to describe the history of the Business and otherwise as permitted by “fair use” principles. 7.11 Background IP License. Seller, on behalf of itself and its Affiliates, hereby grants to Purchaser a worldwide, fully paid-up, royalty-free, irrevocable, non-terminable, perpetual, non- exclusive license under and to all Intellectual Property (other than Marks) owned or controlled by Seller or its Affiliates that was used in the operation of the Business (collectively, the “Licensed Seller IP”) for any and all uses in connection with the operation of the Business and any natural evolutions thereof (including to make, have made, use, sell, offer to sell, and import any product or service, to reproduce, make derivative works of, distribute, display and perform any work, and to use such Licensed Seller IP), with the right to sublicense (including through multiple tiers). Licensed Seller IP shall not include (a) Licensed Software (as defined in the Xtreme License Agreement) and (b) except as necessary to operate the Business, (i) Xtreme NFV, (ii) device firmware outside of the CloudCheck agent and related service assurance functions, and (iii) SDN management and control applications which are required to support the Seller’s transport, access and connectivity products.

From time to time, Seller may request evidence reasonably demonstrating that Purchase has such funds (such as a snapshot of a bank account statement), and Purchaser will provide such evidence within one Business Day of being so requested.

56 7.13 Registration of Transferred Patents and Marks. Seller shall, and shall cause its appliable Affiliates to, reasonably cooperate with Purchaser in correcting any IP Defects in the Transferred Patents and registered and applied for Marks included in the Purchased Intellectual Property, in each case, other than the Patents or Marks set forth on Schedule 7.13 (the “Title Update IP”). To the extent that an IP Defect exists as of the Closing Date with respect to any Title Update IP, then Seller shall reimburse Purchaser for the costs incurred by Purchaser during the period beginning on the Closing Date and ending on the date which is twelve (12) months following the Closing Date to correct any such IP Defect (including any late fees) (the “Title Update Fees”).

Each such offer of employment shall be at the same salary or hourly wage rate and position in effect immediately prior to the Closing Date. Such individuals who accept such offer (whether on or after the Closing Date) or who receive such notice of assignment are hereinafter referred to as the “Transferred Employees.” Subject to applicable Laws, on and after the date of hire by Purchaser (or its Affiliate), Purchaser (or its Affiliate) shall have the right to dismiss any or all Transferred Employees at any time, with or without cause, and to change the terms and conditions of their employment (including compensation and employee benefits provided to them). 8.2 Standard Procedure.

The covenants in this Agreement that either expressly or by their nature are to be performed in whole or in part after the Closing will survive the Closing in accordance with their terms. Notwithstanding anything in this Agreement to the contrary, nothing in this Agreement will, or will be construed to, prevent a claim for fraud.

61 10.2 Indemnification. (a) Subject to Sections 10.1, 10.4 and 10.5 hereof, Seller hereby agrees to indemnify, defend and hold Purchaser and its Affiliates and their respective directors, officers, employees, equity holders, members, partners, agents, attorneys, representatives, successors and assigns (collectively, the “Purchaser Indemnified Parties”) harmless from and against, and pay to the applicable Purchaser Indemnified Parties the amount of, any and all losses, Liabilities, claims, obligations, deficiencies, demands, judgments, damages (including incidental and consequential damages), interest, fines, penalties, claims, suits, actions, causes of action, assessments, awards, costs and expenses (including costs of investigation and defense and attorneys’ and other professionals’ fees), or any diminution in value, whether or not involving a third party claim (individually, a “Loss” and, collectively, “Losses”), arising out of, based upon, attributable to or resulting from: (i) the failure of any of the representations or warranties made by Seller in this Agreement or in any Seller Document to be true and correct in all respects at and as of the date hereof and at and as of the Closing Date; (ii) the breach of any covenant or other agreement on the part of Seller or its Affiliates under this Agreement or in any Seller Document; (iii) (A) the termination of employment by Seller or its Affiliates of any Employee prior to the Closing Date, (B) any Liability relating to, arising under or in connection with any Employee Benefit Plan, including any liability under COBRA, whether arising prior to, on or after the Closing Date and (C) any Liability under WARN, or in each case similar laws or regulations applicable to any Employees (including Transferred Employees) who are terminated; (iv) any Excluded Asset or any Excluded Liability or Retained Employee; and (v) any and all obligations and Liabilities of the Seller for Taxes (or the non- payment thereof) arising out of, based upon, attributable to or resulting from the Business (including the Employees or the Purchased Assets) during any period of time prior to the Closing, including, without limitation, any and all amounts shown as owed by Seller or a Selling Subsidiary pursuant to the Spanish tax certificate obtained in accordance with Section 7.9. (b) Subject to Section 10.1 and 10.4, Purchaser hereby agrees to indemnify, defend and hold Seller and its Affiliates and their respective equity holders, directors, officers, employees, members, partners, agents, attorneys, representatives, successors and permitted assigns (collectively, the “Seller Indemnified Parties”) harmless from and against, and pay to the applicable Seller Indemnified Parties the amount of, any and all Losses, arising out of, based upon, attributable to or resulting from: (i) the failure of any of the representations or warranties made by Purchaser in this Agreement or in any Purchaser Document to be true and correct in all respects at the date hereof and as of the Closing Date;

62 (ii) the breach of any covenant or other agreement on the part of Purchaser under this Agreement or any Purchaser Document; and (iii) any Assumed Liability. (c) The right to indemnification or any other remedy based on representations, warranties, covenants and agreements in this Agreement, any Seller Document or Purchaser Document shall not be affected by any investigation conducted with at any time, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant or agreement. The waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any such covenant or agreements, will not affect the right to indemnification or any other remedy based on such representations, warranties, covenants and agreements. 10.3 Indemnification Procedures. (a) A claim for indemnification for any matter not involving a third-party claim may be asserted by notice to the party from whom indemnification is sought; provided, however, that failure to so notify the indemnifying party shall not preclude the indemnified party from any indemnification which it may claim in accordance with this Article X. (b) In the event that any Legal Proceedings shall be instituted or that any claim or demand shall be asserted by any third party in respect of which indemnification may be sought under Section 10.2 hereof (regardless of the limitations set forth in Section 10.4) (“Third Party Claim”), the indemnified party shall promptly cause written notice of the assertion of any Third Party Claim of which it has knowledge which is covered by this indemnity to be forwarded to the indemnifying party. The failure of the indemnified party to give reasonably prompt notice of any Third Party Claim shall not release, waive or otherwise affect the indemnifying party’s obligations with respect thereto except to the extent that the indemnifying party can demonstrate actual loss and prejudice as a result of such failure. Subject to the provisions of this Section 10.3, the indemnifying party shall have the right, at its sole expense, to be represented by counsel of its choice, which must be reasonably satisfactory to the indemnified party, and to defend against, negotiate, settle or otherwise deal with any Third Party Claim which relates to any Losses indemnified against by it hereunder; provided that the indemnifying party shall have acknowledged in writing to the indemnified party its unqualified obligation to indemnify the indemnified party as provided hereunder. If the indemnifying party elects to defend against, negotiate, settle or otherwise deal with any Third Party Claim which relates to any Losses indemnified against by it hereunder, it shall within five days of the indemnified party’s written notice of the assertion of such Third Party Claim (or sooner, if the nature of the Third Party Claim so requires) notify the indemnified party of its intent to do so; provided that the indemnifying party must conduct its defense of the Third Party Claim actively and diligently thereafter in order to preserve its rights in this regard. The foregoing right of the indemnifying party to assume the defense of any such claim or legal proceeding shall not apply to any claim or legal proceeding that would reasonably be expected to either have a material and adverse impact on the business or reputation of the indemnified party or any Affiliate thereof or result in Losses in excess of the amount that the indemnifying party would be obligated to indemnify the indemnified party for

63 under this Agreement. If the indemnifying party elects not to defend against, negotiate, settle or otherwise deal with any Third Party Claim which relates to any Losses indemnified against by it hereunder, fails to notify the indemnified party of its election as herein provided or contests its obligation to indemnify the indemnified party for such Losses under this Agreement, the indemnified party may defend against, negotiate, settle or otherwise deal with such Third Party Claim. If the indemnified party defends any Third Party Claim, then the indemnifying party shall reimburse the indemnified party for the expenses of defending such Third Party Claim upon submission of periodic bills. If the indemnifying party shall assume the defense of any Third Party Claim, the indemnified party may participate, at his or its own expense, in the defense of such Third Party Claim; provided, however, that such indemnified party shall be entitled to participate in any such defense with separate counsel at the expense of the indemnifying party if (i) so requested by the indemnifying party to participate, (ii) in the reasonable opinion of counsel to the indemnified party a conflict or potential conflict exists between the indemnified party and the indemnifying party that would make such separate representation advisable, or (iii) the claim would result in non-monetary relief that, if granted, could materially and adversely affect the indemnified party or its Affiliates; and provided, further, that the indemnifying party shall not be required to pay for more than one such counsel (plus any appropriate local counsel) for all indemnified parties in connection with any Third Party Claim. Each party hereto agrees to provide reasonable access to each other party to such documents and information as may reasonably by requested in connection with the defense, negotiation or settlement of any such Third Party Claim. The party controlling the defense of a Third Party Claim shall keep the other party reasonably apprised of the status of such action, suit or proceeding and the defense thereof and shall consider in good faith recommendations made by the other party with respect thereto. Notwithstanding anything in this Section 10.3 to the contrary, neither the indemnifying party nor the indemnified party shall, without the written consent of the other party, settle or compromise any Third Party Claim or permit a default or consent to entry of any judgment unless the claimant (or claimants) and such party provide to such other party an unqualified release from all Liability in respect of the Third Party Claim. If the indemnifying party makes any payment on any Third Party Claim, the indemnifying party shall be subrogated, to the extent of such payment, to all rights and remedies of the indemnified party to any insurance benefits or other claims of the indemnified party with respect to such Third Party Claim. (c) After any final decision, judgment or award shall have been rendered by a Governmental Body of competent jurisdiction and the expiration of the time in which to appeal therefrom, or a settlement shall have been consummated, or the indemnified party and the indemnifying party shall have arrived at a mutually binding agreement, in each case with respect to an Third Party Claim hereunder, the indemnified party shall forward to the indemnifying party notice of any sums due and owing by the indemnifying party pursuant to this Agreement with respect to such matter and the indemnifying party shall pay all of such remaining sums so due and owing to the indemnified party. 10.4 Limitations on Indemnification for Breaches of Representations and Warranties. (a) An indemnifying party shall not have any liability under Section 10.2(a)(i) or Section 10.2(b)(i) except to the extent that the aggregate amount of Losses incurred by the indemnified parties and indemnifiable thereunder based upon, attributable to or resulting from the failure of any of the representations or warranties to be true and correct exceeds $250,000 (the

64 “Deductible”) and, in such event, the indemnifying party shall be required to pay the entire amount of all such Losses (i.e., from the first dollar of such Losses including the Deductible); provided that the Deductible limitation shall not apply to Losses related to the failure to be true and correct of any of the representations and warranties set forth in Sections 5.1 (organization and good standing), 5.2 (authorization of agreement), 5.4 (title to purchased assets; sufficiency), 5.6 (taxes), 5.11 (employee benefits), 5.15 (environmental matters) and 5.18 (financial advisors) and 6.1 (organization), 6.2 (authorization of agreement) and 6.7 (financial advisors). (b) Neither Seller nor Purchaser shall be required to indemnify any Person under Section 10.2(a)(i) or 10.2(b)(i) for an aggregate amount of Losses exceeding $4,000,000 in connection with Losses related to the failure to be true and correct of any of the representations or warranties of Seller or Purchaser, respectively; provided, that (i) Seller shall not be required to indemnify any Person under Section 10.2(a)(i) for an aggregate amount of Losses exceeding the Purchase Price in connection with Losses related to the failure to be true and correct of any of the representations or warranties contained in Sections 5.1 (organization and good standing), 5.2 (authorization of agreement), 5.4 (title to purchased assets; sufficiency), 5.6 (taxes), 5.11 (employee benefits), 5.15 (environmental matters) and 5.18 (financial advisors) and 6.1 (organization), 6.2 (authorization of agreement) and 6.7 (financial advisors) and (ii) Seller shall not be required to indemnify any Person under Section 10.2(a)(i) for an aggregate amount of Losses exceeding $8,000,000 in connection with Losses related to the failure to be true and correct of the representations or warranties of Seller contained in Section 5.9 (intellectual property). (c) For purposes of determining the failure of any representations or warranties to be true and correct, the breach of any covenants or agreements, and calculating Losses hereunder any materiality or Material Adverse Effect qualifications in the representations, warranties, covenants and agreements shall be disregarded. 10.5 Tax Treatment of Indemnity Payments. Seller and Purchaser agree to treat any indemnity payment made pursuant to this Article X as an adjustment to the Purchase Price for all Tax purposes, to the extent permitted by applicable Law. If, notwithstanding the treatment required by the preceding sentence, any indemnification payment under Article X (including this Section 10.5) is determined to be taxable to the party receiving such payment by any Taxing Authority, the paying party shall also indemnify the party receiving such payment for any Taxes incurred by reason of the receipt of such payment and any Losses incurred by the party receiving such payment in connection with such Taxes (or any asserted deficiency, claim, demand, action, suit, proceeding, judgment or assessment, including the defense or settlement thereof, relating to such Taxes). ARTICLE XI TAXES 11.1 Transfer Taxes. Seller and Purchaser shall each pay one-half (1/2) of any and all sales, use, stamp, documentary, filing, recording, transfer, real estate transfer, stock transfer, gross receipts, registration, duty, value added, securities transactions or similar fees or taxes or governmental charges (together with any interest or penalty, addition to tax or additional amount imposed) as levied by any Taxing Authority in connection with the transactions contemplated by

65 this Agreement (collectively, “Transfer Taxes”), regardless of the Person liable for such Transfer Taxes under applicable Law. Seller Parties shall timely file or caused to be filed all necessary documents (including all Tax Returns) with respect to Transfer Taxes. Purchaser shall (i) remit its portion of such Transfer Taxes to the applicable Seller Party within ten (10) days of written request by Seller, which request will include reasonable documentary evidence of payment by such Seller Party of the applicable Transfer Taxes, and (ii) reasonably cooperate with Seller with respect to taking such actions so as to minimize or avoid any sales or use taxes to the extent legally permissible, it being understood and agreed that it shall be reasonable for Purchaser to refuse to take any action requested by Seller to the extent that such action would in any way be detrimental to Purchaser, financially or otherwise. 11.2 Prorations. The Seller Parties shall bear all property and ad valorem tax liability with respect to the Purchased Assets if the lien or assessment date arises prior to the Closing Date irrespective of the reporting and payment dates of such taxes. All other real property taxes, personal property taxes, or ad valorem obligations and similar recurring taxes and fees on the Purchased Assets for taxable periods beginning before, and ending after, the Closing Date, shall be prorated between Purchaser and Seller Parties as of the Closing Date. The Seller Parties shall be responsible for all such taxes and fees on the Purchased Assets accruing during any period up to and including the Closing Date. Purchaser shall be responsible for all such taxes and fees on the Purchased Assets accruing during any period after the Closing Date. With respect to Taxes described in this Section 11.2, the Seller Parties shall timely file all Tax Returns due before the Closing Date with respect to such Taxes and Purchaser shall prepare and timely file all Tax Returns due after the Closing Date with respect to such Taxes. If one party remits to the appropriate Taxing Authority payment for Taxes, which are subject to proration under this Section 11.2 and such payment includes the other party’s share of such Taxes, such other party shall promptly, upon the other party’s written request, (and in any case within ten (10) days of receipt of such request) reimburse the remitting party for its share of such Taxes. Any such request will include reasonable documentary evidence of payment by the applicable party of the applicable Taxes. 11.3 Cooperation on Tax Matters. Purchaser and Seller shall use commercially reasonable efforts to furnish or cause to be furnished to each other, as promptly as practicable, such information and assistance relating to the Purchased Assets and the Assumed Liabilities as is reasonably necessary for the preparation and filing of any Tax Return, claim for refund or other filings relating to Tax matters, for the preparation for any Tax audit, for the preparation for any Tax protest, for the prosecution or defense of any suit or other proceeding relating to Tax matters. Purchaser and Seller shall reasonably cooperate with each other with respect to taking such actions so as to minimize or avoid any Taxes to the extent legally permissible, it being understood and agreed that it shall be reasonable for either party to refuse to take any action requested by the other party to the extent that such action would in any way be detrimental to sch party, financially or otherwise. 11.4 Tax Clearance Certificates. At Purchaser’s request, Seller shall (or shall cause its Affiliate to) notify all of the Taxing Authorities for the jurisdictions set forth on Schedule 5.6(c) of the transactions contemplated by this Agreement in the form and manner required by such Taxing Authorities, if the failure to make such notifications or receive any available tax clearance certificate (“Tax Clearance Certificate”) could subject the Purchaser to any Taxes of Seller or its Affiliates. If, in respect to any application for Tax Clearance Certificates made pursuant to this

66 Section 11.4, any Governmental Body asserts that Seller is liable for any Tax, Seller shall promptly pay, or shall cause to be paid, any and all such amounts and shall provide evidence to the Purchaser that such liabilities have been paid in full or otherwise satisfied. 11.5 Deferred Revenue. The parties agree (a) that for U.S. federal and all applicable state and local income Tax purposes, any Assumed Liability that is attributable to deferred revenue shall not be treated as giving rise to taxable income of Buyer under Xxxxx X. Xxxxxx Corp., 326 F.2d 67 (8th Cir. 1964), or otherwise, and (b) not to take any position on any Tax Return that is inconsistent with the treatment described in clause (a) immediately foregoing. ARTICLE XII MISCELLANEOUS 12.1 Expenses. Except as otherwise provided in this Agreement, each of the Seller Parties and Purchaser shall bear their own expenses incurred in connection with the negotiation and execution of this Agreement and each other agreement, document and instrument contemplated by this Agreement and the consummation of the transactions contemplated hereby and thereby. 12.2 Specific Performance. Seller acknowledges and agrees that the breach of this Agreement would cause irreparable damage to Purchaser and that Purchaser will not have an adequate remedy at law. Therefore, the obligations of Seller under this Agreement, including Seller’s obligation to sell the Purchased Assets to Purchaser, shall be enforceable by a decree of specific performance issued by any court of competent jurisdiction, and appropriate injunctive relief may be applied for and granted in connection therewith. Such remedies shall, however, be cumulative and not exclusive and shall be in addition to any other remedies which any party may have under this Agreement or otherwise. 12.3 Submission to Jurisdiction; Consent to Service of Process. (a) The parties hereto hereby irrevocably submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (provided that if the Court of Chancery does not exercise jurisdiction over any matter, then any federal or state court located within the State of Delaware) over any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby and each party hereby irrevocably agrees that all claims in respect of such dispute or any suit, action proceeding related thereto may be heard and determined in such courts. The parties hereby irrevocably waive, to the fullest extent permitted by applicable law, any objection which they may now or hereafter have to the laying of venue of any such dispute brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. (b) Each of the parties hereto hereby consents to process being served by any party to this Agreement in any suit, action or proceeding by the delivery of a copy thereof in accordance with the provisions of Section 12.6.

67 12.4 Entire Agreement; Amendments and Waivers. This Agreement (including the schedules and exhibits hereto) represents the entire understanding and agreement between the parties hereto with respect to the subject matter hereof. This Agreement can be amended, supplemented or changed, and any provision hereof can be waived, only by written instrument making specific reference to this Agreement signed by the party against whom enforcement of any such amendment, supplement, modification or waiver is sought. No action taken pursuant to this Agreement, including without limitation, any investigation by or on behalf of any party, shall be deemed to constitute a waiver by the party taking such action of compliance with any representation, warranty, covenant or agreement contained herein. The waiver by any party hereto of a breach of any provision of this Agreement shall not operate or be construed as a further or continuing waiver of such breach or as a waiver of any other or subsequent breach. No failure on the part of any party to exercise, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such party preclude any other or further exercise thereof or the exercise of any other right, power or remedy. All remedies hereunder are cumulative and are not exclusive of any other remedies provided by law. 12.5 Governing Law; Waiver of Jury Trial. (a) This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware applicable to contracts made and performed in such State.
